Description

Technical Field

[0001] This utility model belongs to the field of fully mechanized mining face equipment, specifically relating to a push-pull connection device for a fully mechanized mining face support in a coal mine. Background Technology

[0002] A fully mechanized coal mining face, also known as a coal mining face, is a working face that uses coal mining machines, self-propelled hydraulic supports, flexible scraper conveyors, and other auxiliary equipment (such as communication and lighting devices) for production. The fully mechanized coal mining face support is one of the important pieces of equipment in a fully mechanized coal mining face. It is mainly used to support the roof of the coal seam, prevent the roof from collapsing, provide working space for the coal mining machine and other equipment, and ensure the safe operation of coal mining.

[0003] In the existing technology, when the mining face platform moves, the coal mine debris falling behind it needs to be collected. Usually, a push-pull collection device is connected to the fully mechanized mining face support. However, due to the relatively narrow space behind it and the inconvenience of cleaning, the push-pull collection device may experience positional displacement and difficulty in moving during the process.

[0004] Therefore, a push-pull connection device for a fully mechanized coal mining face support is proposed, which has a cleaning, feeding and collecting structure. After the device is displaced, it can automatically collect the coal mine gravel in front of the collection box, thus solving the problem that the narrow space behind the collection platform makes it inconvenient to move the push-pull device. Utility Model Content

[0005] To overcome the problem that the limited space behind the existing data acquisition platform makes it difficult to move the push-pull device.

[0006] The technical solution of this utility model is as follows: a push-pull connection device for a fully mechanized coal mining face support, including a base; a collection box is provided behind the base; a feeding component is provided on the collection box; a limiting groove is opened at the front end of the collection box; a partition is fixedly connected to the upper and lower ends of the inner wall of the limiting groove; a first electric cylinder is fixedly connected to the left and right ends of the partition; a first push block is fixedly connected to one end of the telescopic rod of the two first electric cylinders that are far apart from each other; a second push block is fixedly connected to the front end of the first push block; and the two second push blocks are attached to each other at their close ends.

[0007] Preferably, when it is necessary to collect coal in front of the push-pull collection device, the collection box is moved. After the fully mechanized mining face device stops moving, the two first electric cylinders are activated to drive the first push block and the second push block to push soil to both sides of the collection box, thereby pushing and gathering the coal crushed stone in front of the collection box. Then, the feeding component is used to push the coal crushed stone into the storage trough.

[0008] Preferably, a movable plate is provided at the lower end of the base; cylinders are fixedly connected to the left and right ends of the base; a fixing block is fixedly connected to the rear end of the telescopic rod of the cylinder; and a chain is fixedly connected to the rear end of the fixing block.

[0009] Preferably, the other ends of the two chains are fixedly connected to a collection box; the upper end of the collection box is provided with a storage trough.

[0010] Preferably, the feeding assembly includes a motor, a rotating arm, a feeding box, a second electric cylinder, and a third pusher; motors are fixed to the outer walls of the left and right ends of the collecting box; and rotating arms are fixed to one end of the output shafts of the two motors that are far apart from each other.

[0011] Preferably, a feed box is snap-fitted to one end of the two rotating arms that are close to each other; a second electric cylinder is fixedly connected to the rear end of the feed box; and a third pusher is fixedly connected to the output shaft of one end of the two second electric cylinders that are close to each other through the feed box.

[0012] Preferably, the lower end of the collection box is fixed with two lower support plates, which can support the lower end of the storage tank.

[0013] Preferably, the lower end of the collection box is flush with the lower end of the moving plate, and the lower end of the collection box pushes the coal mine crushed stone at the front end of the collection box.

[0014] The beneficial effects of this utility model are:

[0015] 1. By displacing the collection box, after the fully mechanized mining face device stops displacing, the two first electric cylinders are activated to drive the first push block and the second push block to push soil to both sides of the collection box, thereby pushing and gathering the coal mine crushed stone in front of the collection box. Then, the feeding component is used to push the coal mine crushed stone into the storage trough.

[0016] 2. The movable plate under the base can move the base and the collection box as a whole. After the base has moved, the cylinder is opened, and the fixed block on the cylinder pulls the collection box on the chain, so that the collection box is stretched towards the base. This solves the problem that the coal mine gravel in front of the collection box is inconvenient to clean, which makes it difficult to move.

[0017] 3. When the first and second push blocks push the coal and gravel in front of the collection box toward the left and right ends of the collection box, the coal is fed into the feeding box. Then the motor is turned on, and the output shaft of the motor drives the rotating arm to rotate downward. When the feeding box rotates to the top of the collection box, the second electric cylinder is turned on, and the extension rod of the second electric cylinder drives the third push block to push toward the storage trough, thereby pushing the coal and gravel in the feeding box into the storage trough for collection.
