Background of invention

The present invention relates to the design of the hopper for cement for mining machines, which contains a stirrer, a hopper for cement and feed device for feeding cement from the lower end of the hopper for cement to the mixer.

Mining devices are used for cementation grouting bolts in the holes drilled for them and for pumping cement into the holes or various clastic rocks. The required cement is supplied from a special hopper for cement, which is located on top of the mining machine, the agitator below, by means of a separate feed device, such as a feed screw mounted on the bottom of the silo for cement in the mixer, the cement is mixed with water for making concrete for grouting. As the hopper for cement is at the top of the mining machine, it is relatively high, and the cement is loaded into the hopper is heavy and difficult without using a separate boot of the bucket. This requires a separate working platform, which is reached by a flight of stairs and which should be raised cement bags usually work in order to raise them to the edge of the hopper for cement and pour into it.

Brief description of the invention

The aim of the present invention is the I create designs hopper for cement, providing a more simple and easy loading and using the hopper than existing solutions.

Tank design for cement according to the invention differs in that the hopper for cement is a separate element, and the mining machine is provided with moving means for moving the hopper for cement between the position of use on top of the mining machine and a filling position different from a position of use.

The basic idea of the invention lies in the fact that the hopper for cement is a separate element cassette/box type, which moves to fill the position of use on top of the mining machine to another position different from a position of use and located to selectively lower than the position of use, i.e. to the position of the fill close to the ground level or even at ground level. In this case, the hopper for cement is high enough on top of the mining machine for feeding cement into the mixer, and, on the other hand, is easy and simple to fill empty hopper for cement or replace it with a full tank of cement. According to a variant embodiment of the invention the hopper for cement is a separate tape/box, which is delivered filled with cement, mining machine rises and moves the tool at the top of the mining machine, and when the hopper is empty, it goes down NR the V to the ground, and selected a new silo for cement, pre-filled with cement. According to the second variant embodiment of the invention, each hopper for cement is equipped with a special feed screw, a motor drive which is connected to the control system of the mining machine when selected a new bunker. According to another variant implementation of the feed screw is stationary mounted on the mining machine and the hopper for cement is a container filled with cement at the bottom of which there is a hole that can be opened and closed, and a hopper for cement raised position at the top of the feed screw, and open the hole for cement supply in the supply WinTV this description and the claims the position of use refers to the position in which the cement can be enjoyed from the hopper for cement in the mixer, and the position of the fill refers to the position in which the cement may be filed in the bin for cement, or hopper for cement can be detached from the transporting means and replaced by another silo for cement, cement filled.

Detailed description of some embodiments of the invention

1 schematically shows the mining machine 1, which in this case is a device for anchoring. It includes a bearing support 2, to which is attached with its first end of the arrow 3. On the second end of the boom 3 is mounted rotatable, the installation 4 anchoring, which contains drilling machine 5 on the breed, moving the traveling beam 5a, the feed device 6 bolts, moving the traveling beam 6a, shop 6b bolt and supply hose 7 for cementitious material. The hose 7 is installed on the coil 8 for hose where necessary length of hose may be filed in the hole for feeding cementitious material in the hole to introducing anchor bolt.

On the bearing support 2 is also mounted mixer 9 through which the cement filed from the hopper 10 for cement, mixed with water for producing the desired weight so that it may is be passed through the supply hose 7.

Typically, the agitator 9 is a device which is stationary mounted at a predetermined height and containing container, the agitator is driven by a separate motor stirrer. The container is also connected to the supply pump (not shown)which pumps up prepared cementitious material in the supply hose 7. The mixer of this type is known, the design and operation of mixers and related parts obvious to a person skilled in the art. As this is not relevant to the present invention, it is not described in more detail in this description.

To simplify facilitate the use of stirrers may be mounted mixer with the ability to move vertically a suitable driving tool, such as a hydraulic cylinder, so that during operation it can be lowered, even to ground level, and as it moves mining machines it can be raised high enough not to be damaged due to the irregularities of the earth or rock. In addition, the trajectory of the hopper for cement may be such that when lowering the hopper moves outward from the bearing support mining machine that makes work easier, and when lifting the hopper moves closer to the bearing support mining machine, whereby it is more compact side and, thus, facilitates movement of the mining machine.

The hopper 10 for cement fitted cap, which will be described later in connection with figure 2-4b, contains the input device, usually the feed screw 11, whereby the cement is moved from the hopper 10 for cement to the mixer 9, so that it will fall into the mixer 9. The feed screws 11, their design and operation are well known, and therefore they are not described herein in more detail, with the exception of signs that relate to the invention.

Figa and 2b depict views from the rear of the mining machine of figure 1, with the hopper 10 for cement is in a position of use and position filling, respectively.

The hopper 10 includes a cover 10a, which closes the inlet of the cement when the cement is not fed into the hopper. The cover can be mounted relative to the hopper and moving the tool so that it opens automatically when the hopper 10 for cement down. On the other hand, in some situations, for example, when the mining machine is serviced, for a cover you should be able to stay above the hopper 10, whereby the hopper can be used as a working platform and steps, until serviced the engine behind the hopper for cement and other equipment. In addition, when necessary, may be provided with a separate lifting equipment or other mechanism to cover 10a.

On fig.2b shown a hopper for cement is, lowered by the lifting levers 12 and a lifting cylinder 13, the moving means sufficiently down next to the mining machine so that makes it easier filling of the hopper. The hopper 10 for cement may be omitted for a location on earth or rock below. When necessary, the hopper 10 can be detached from the lifting arms 12, using a simple recording from the latch or the like. Alternatively, fasteners at the ends or edges of the hopper for cement can be made with the possibility of a disconnection from the lifting arms when the lift arms 12 are lowered enough down until the hopper 10 is located on the ground or rock. The hopper can then be left at the place, and can be picked up another bin for cement by moving the mining machine in the longitudinal direction to reach a new silo for cement, and lifting the lifting levers at this point for fixing to supports the new silo for cement.

Figa and 3b are schematic views from the side of a variant embodiment of the invention in section along the line A-A. In this embodiment, the feed screw 11 is mounted stationary on the bottom of the hopper 10 for cement, and when applied the method of replacing the hopper for cement, each bin contains individual feed screw. Engine 11a rotating the mode of the conveying screw is for example, a hydraulic motor, which is connected by hoses to a control system of the mining machine to be controlled by its control devices.

Figa and 4b depict side views of a second variant implementation in section along the line B-B. In this case, the hopper 10 for cement is just a box filled with cement, and the feed screw 11 is rigidly mounted on top of the mining machine 1. In this case, the lower end of the hopper 10 for cement contains, for example, the closing flaps 10b, which are fixed in the locking position the locking means 10c, when the hopper for cement fill. The lower part of the hopper 10 for cement also preferably tapers conically downward, and the edge which is located above the feed screw 11 and partly shown in the drawings, extends respectively. Therefore, when the hopper for cement will raise into place, it will be located close their edges, inside edges 11b of the feed screw 11. In this situation, depending on the design, by pulling or turning the locking means 10c in the direction from under the edges of the closing flaps 10b, the closing flaps 10b rotates downward with respect to the walls of the hopper for cement, and the cement will be able to fall on the feed screw 11.

Figure 5 shows a variant embodiment of the invention, in which the position of the filling hopper for cement location is behind the mining machine, not next to it. In this embodiment, the moving means 15 includes a bolt 15, which is mounted rotatably around a vertical axis relative to the mining machine so that the hopper 10 for cement can be rotated back mining machines from a position of use, and by turning the bolt down, it can be lowered to the position is filled. Accordingly, when rotating the boom up hopper 10 for cement can be lifted up from the filling position and then rotated to its position of use. One end of the boom is attached to the hopper for cement in any known way, most preferably so that the hopper remains in the same position relative to the boom 15 and thus rotates approximately 90 degrees between a position of use and position of the fill.

Figure 6 shows another variant embodiment of the invention, which contains the guide rails 16 on top of the mining machine for movement of the hopper 10 for cement in the longitudinal direction of the mining machine from the use position to the rear section of the mining machines and, respectively, from the rear section to a position of use. In this embodiment, the rear end of the mining machine is also lifting device 17, whereby the hopper may be moved with reuleaux the back of the mining machine and down to the filling position, and, accordingly, from the position of the filling on the rails 16.

In the above description with reference to the drawings the present invention is described only as an example and is in no way limited to them. The appearance of the hopper 10 for cement may vary depending on mining machines and other used equipment. The location and design of the feeding screw 11 can be anything that is suitable for hoppers for cement. Form of lifting levers 12 can be changed and, when necessary, the levers may be made of multiple concatenated pieces. Instead of lifting levers is also possible to use different arrows or similar to move the hopper 10 for cement. Instead of lifting cylinder 13 it is possible to use a conventional hydraulic motors and the like for turning the lifting levers. Instead of conveying screw it is possible to use the funds supply of some other type, such as feeding devices based on compressed air. The position of the filling does not need to be located below the position of use. If the hopper for cement can be raised from the position of the filling fork lift or some such device, and accordingly a new silo for cement may be placed in the filling position, the filling position and the position can use the set, for example, at the same height or position of the filling may be even higher than the position of use.
