Mountain harvester

 

The invention relates to mining machinery and can be used in the construction of mining machines. Object of the invention is the expansion of the scope of the mining combine with loader and increasing the agility of mountain harvester when working with an overhead crane. Mountain harvester contains movable in the vertical plane of the conveyor and an overhead crane. The connection of the bridge conveyor with conveyor performed using a ball device having installed on bridge tailpiece ball bearing, socket under a ball bearing and two procrasti connecting a ball bearing with a socket. Ball device is equipped with optional shaft mounted on bridge tailpiece for axial rotation and located perpendicular to the longitudinal axis of the bridge crane. Ball bearing is rigidly connected with the shaft, and a nest under a ball bearing mounted on a movable conveyor. 4 Il.

The invention relates to the field of mining engineering and can be used in the construction of mining machines. Famous mountain combines PCSM and Karaganda 7/15S( see Baser J. I., Crotalin C. I., Sokolov, Y. L. Tunneling machines. - M.: Nedra, 1974, with the world bearing is rigidly connected to the drive section. The disadvantage of this technical solution is limited maneuverability harvesters at work due to the fact that the ball joint has a limited angle of rotation in the vertical plane. When a significant change in position of the harvester relative to the loader, for example, when the steep rise of the combine, the ball bearing works at the break, while reducing the reliability of connection of the loader with the combine.

The closest technical solution adopted for the prototype is continuous miner PC-9R (cm Baser J. I., Crotalin C. I., Sokolov, Y. L. Tunneling machines. - M.: Nedra, 1974, S. 106, 107, 121, 158, 159), which ball joint is suspended from an overhead crane to the rear of the harvester to a stationary scraper conveyor. The lack of such connection material handler with harvester is also limited maneuverability of the harvester at work in addition, this connection cannot be used for moving in the vertical plane of the scraper conveyor harvester c is connected to the conveyor loader, at large angles of ascent scraper conveyor.

The present invention is the expansion of the scope of the mining combine with an overhead loader, Avesta mountain harvester, including movable in the vertical plane of the conveyor and an overhead loader, in which the connection of the bridge conveyor with conveyor performed using a ball device having installed on bridge tailpiece ball bearing, socket under a ball bearing and two procrasti connecting a ball bearing with a socket, a ball device is equipped with an additional shaft mounted on bridge tailpiece for axial rotation, perpendicular to the longitudinal axis of the bridge crane, with spherical bearing is rigidly connected with the shaft, and a nest under a ball bearing mounted on a movable conveyor.

Mapping declared mountain harvester prototype allows to make a conclusion about the absence in the latter of signs similar to a distinctive signs to declare mining combine.

- Ball device is equipped with optional shaft mounted on bridge tailpiece for axial rotation, perpendicular to the longitudinal axis of the bridge crane.

- Ball bearing is rigidly connected with the shaft, and a nest under a ball bearing mounted on a movable conveyor.

The set of features saleemullah prior art, therefore, the authors believe that the object is new and involves an inventive step in view of the fact that the combination of signs, namely: - ball device is equipped with optional shaft mounted on bridge tailpiece for axial rotation, perpendicular to the longitudinal axis of the bridge loader; - the ball bearing is rigidly connected with the shaft, and a nest under a ball bearing mounted on a movable conveyor, solves the problem of the invention to expand the scope of mining combine with an overhead crane, as well as improve the maneuverability and reliability mountain harvester when working with an overhead crane.

These characteristics are related to each other so that when the removal of one of them disappears produced by the invention of the technical result.

The invention also represents a step in the development of technology and is a progressive, because it allows one to extend the scope of the mining combine with loader and improve maneuverability mountain harvester when working with an overhead crane.

Mountain harvester, which claimed the invention may find wide application in the mining sector and other sectors ha when working mountain harvester is provided for those : - ball device is equipped with optional shaft mounted on bridge tailpiece for axial rotation, perpendicular to the longitudinal axis of the bridge crane.

This solution allows you to move the crane around the shaft by changing the position of the harvester or the lifting of the scraper conveyor, thereby to reduce the load on the towball and improve the reliability of this connection and maneuverability mountain harvester at work.

- ball bearing is rigidly connected with the shaft, and a nest under a ball bearing mounted on a movable conveyor.

This solution allows you to change the position of the bridge tailpiece height relative to the soil, and thereby enables loading to another vehicle, i.e., to expand the scope of the mining combine with bridge tailpiece for different schemes of loading rock mass in the development.

The essence of the invention is illustrated by drawings.

global device (section a-a).

Mountain harvester contains (Fig. 1-4) is movable in the vertical plane of the conveyor 1, the bridge crane 2, the connection of the bridge conveyor 2 to conveyor 1 is made via a ball device 3 having mounted on bridge tailpiece 2 ball bearing 4, socket 5 under a ball bearing 4 and two procrasti 6 connecting a ball bearing 4 with the socket 5. Ball device 3 is provided with an additional shaft 7, mounted on a bridge stacker 2 with the possibility of axial rotation and perpendicular to the longitudinal axis I-I of bridge material handler 2 ball bearing 4 is rigidly connected with the shaft 7, and the slot 5 of a ball bearing 4 is mounted on a movable conveyor 1.

The work of the mining harvester is as follows.

When working mountain harvester progresses bridge crane 2 is moved over the mountain harvester, drawing one end of the ball joint 4 on the conveyor 1 with the other end on the monorail, located in the development.

When maneuvering mountain combine the right or left of the mountain harvester rotates around the ball 4 ball device 3, without changing the position of the bridge material handler 2. By changing the position of the mining machine in the vertical placerita 3. When reaching a big turn corners greater than the angle of ball bearings 4 in a spherical device 3, the rotation is carried by the shaft 7, while not transmitting the bending load on a ball bearing 4, thereby increasing the reliability of connection of the mining combine and bridge material handler 2. For example, in mining combine with loading trolley produce lift conveyor 1 mountain harvester at a considerable angle, and the rotation of the bridge material handler 2 is due to the shaft 7, thus providing the necessary lifting of the bridge material handler 2 for mining combine in this technological scheme. Mountain harvester through supply towball additional shaft and connections of a bridge crane with a movable conveyor allows the use of different technological schemes of loading, while increasing the agility of mountain harvester in the development in his work, as well as to improve the reliability of connection of the mountain harvester with an overhead crane.
