The executive body of the mining machine
(57) Abstract:Usage: the invention relates to mining equipment and can be used in machines for sinking mines, mainly in the tunneling combines selective action. Entity: Executive body includes disks with cones, connected with a planet carrier which is connected with the drive shaft. Each of the discs is mounted on the output shaft placed in the driver /in the case/, and associated gear reducer, worm wheel and worm, which is connected with the housing Executive body or connected with additional adjustable actuator attached to the housing Executive body. Gear ratio gear of each gear drive may be different, at least one of the gears drives are made with gear ratio than the gear ratio of the other two gears. Changing the number of revolutions of the worm with the help of an adjustable actuator is achieved by changing step of cutting rocks. Constructive decision of the Executive body allows you to change the direction of the Executive body, the scheme of destruction and the step of cutting that ensures the destruction of rocks in the most is echnique and can be used in machines for sinking mines, mainly in the tunneling combines selective action.Known Executive body for the destruction of rocks, including the gearbox is placed in the enclosure drove installed on the driver drives the cutting tool, and the worm worm pair, which is associated with each of the gears that transmit the rotation of the disks, and is rigidly secured on the lamp installed in the well.However, the design of the Executive body does not allow you to change the direction of the Executive body, the scheme of slaughtering and cutting step of cutting, as a worm, built-in reducer, mounted stationary relative to the borehole wall. To ensure the immobility of the worm and the Executive body in General requires spreading out the machine in side output.The task of the invention is the creation of the Executive body of the digging machine electoral actions that allow you to change the direction of the Executive body, the diagram of the destruction of the shaft and the step of cutting.The problem is solved in that in the Executive body, including the drive, drove, mounted on the shaft of the actuator, drives the cutting tool, each of which (ROM) connected to the last (worm worm pairs) rigidly or via the optional adjustable actuator connected to the housing Executive body, and at least one of the gears drives are made with gear ratio than the gear ratio of the other gears.This embodiment Executive body allows you to change the direction of the Executive body in space, destroying the rock in the best mode, changing the scheme of cutting rocks and the step of cutting depending on geological conditions and physico-mechanical properties of rocks.In Fig. 1 and 2 schematically presented to the Executive body (options); Fig. 3 section a-a in Fig. 1; Fig. 4 section b-B in Fig. 1.The Executive body of the mining machine includes a disk 1 placed on the drive rod 2, which is connected with the drive shaft 3.On disc 1 is placed a cutting tool, such as a freely mounted cone 4.Each of the disk 1 is mounted on the output shaft placed in the driver 2 (in his case), and associated gear 5-6-7 gear, worm wheel 8 with the worm 9, which is connected to the housing body (Fig. 1) or is connected with additional adjustable actuator 10, fixed to the body 11 of the Executive body (Fig. 2).Gear ratio gear 5-6-7 of cadm number, other than the gear ratio of the other two gears.The device operates as follows.When enabled, the actuator 3 is driven carrier 2, which rotates and worm wheel 8. The worm wheel 8 obkatyvalisj the worm 9 and through the reduction gear of each of the disks 1 (gear 7-6-5) transmit the rotation of the disk 1 with 4 cones that destroy the slaughter.Depending on the gear ratio of gears (gears 7-6-5) and worm pairs 9-8 per revolution took 2 is the rotation of the disc 1 with cones and surface treatment of the face with the selected spacing between lines of cut.Additional adjustable actuator 10 can change the number of revolutions of the worm 9 (Fig. 1). If there is no need to change the step of cutting, the worm remains stationary (Fig. 2).Thus, the proposed design of the decision of the Executive body of the mining machine allows you to change the direction of the Executive body, the diagram of the destruction of the shaft and the step of cutting that ensures the destruction of rocks in the best mode, and carry out production of various sections. The Executive body of the mining machine, comprising a housing, drive, drove, installed the driver, and the worm worm pairs, kinematically associated with each gear, wherein the worm worm pairs rigidly or via the optional adjustable actuator connected to the housing Executive body and at least one of the gears drives are made with gear ratio than the gear ratio of the other gears.
FIELD: open-cast mining.
SUBSTANCE: invention relates to continuous-operation self-propelled device designed for checking possibility of mining mineral materials and taking out interlayers whose properties, from point of view of their breaking and further transportation, are of vital importance at open cast mining. Proposed device has running gear, frame with drive unit and control panel and cutting drum arranged before running gear and equipped with cutting tools. Said drum is installed in supports of carrying frame for rotation around horizontal axis and is made for adjusting position in height by means of cylinder installed between frames and carrying frame. Crawler-type running gear is used. Cutting drum passes over entire width of device, and it is furnished with guide partitions and guard shield, is functionally connected with chute-like housing and is made for stepless change of speed of rotation, speed of feed and adjusting transverse tilting from one of two sides relative to working platform owing to vertical adjustment of position of one of hinge joints connection device frame and carrying frame which is made in form of forked rotary cantilever.
EFFECT: improved operating capabilities of device.
5 cl, 5 dwg
FIELD: mining machinery manufacturing, particularly machines which completely free the mineral from the seam.
SUBSTANCE: heading machine comprises executive tool including boom with body and cutting crown, as well as feeder with nose and rock raking device. Rock raking device is installed in lower boom part facing ground. Rock raking device is plate shaped as rectangular trapezoid. Minor trapezoid side is located at cutting edge, major one facing feeder nose. The plate is rigidly connected to shaft displaced towards minor trapezoid side. The shaft is installed in socket formed in lower boom part facing ground. The plate may rotate with respect to longitudinal shaft axis. Stops are formed on boom body from both sides of longitudinal boom body axis and spaced a distance providing plate rotation through α angle, wherein 30°≤α≤45°.
EFFECT: simplified structure and increased efficiency of machine loading near face.
