The utility model relates to the technical field of coal mine conveying, and discloses a coal mine excavation conveying device which comprises two sets of baffles, a frame is placed on one side between the two sets of baffles, and a transverse frame is fixedly installed at the bottom of the frame. A bottom plate is fixedly installed at the bottoms of the two baffles, and supporting rods are fixedly installed at the four corners of the bottom plate. Servo motors are fixedly mounted on the two sides of the front wall of the frame. According to the coal conveying device, the frame, the conveying belt and the transverse frame are arranged, in the using process of the conveying device, the frame can be stably supported through the transverse frame and the bottom plate, meanwhile, the servo motor drives the transmission roller to rotate, the transmission roller drives the conveying belt to move, coal can be conveyed to the bottom plate, meanwhile, the conveying belt is obliquely designed, and one end of the conveying belt is located at the low position; when a worker uses the shovel for shoveling, the shovel does not need to be lifted to a higher height, and the coal shoveling burden of the worker is reduced.

The present application belongs to the technical field of coal mine electromechanical, and particularly relates to a coal mine electromechanical transport device. The coal shoveling assembly in the device is arranged at the front of the vehicle body, and is used for shoveling coal and conveying the coal to the inside of the vehicle body through the upper end of the vehicle body; the coal pressing assembly comprises a lower pressing piece, the lower pressing piece is movably arranged in the inside of the vehicle body along the front-rear direction of the vehicle body and is capable of moving up and down, and the lower pressing piece is capable of moving to a avoiding state and a working state; when the lower pressing piece is in the avoiding state, the lower pressing piece is located at the upper part of the rear side of the vehicle body, and the coal shoveling assembly is capable of conveying the coal to the inside of the vehicle body through the upper side of the front of the vehicle body; when the lower pressing piece is in the working state, the lower pressing piece is capable of moving along the front-rear direction of the vehicle body and moving up and down, so as to compact the coal in the inside of the vehicle body. Thus, the device realizes the improvement of the filling compactness of the coal on the transport equipment, thereby improving the effective payload of single transport, reducing the transport energy consumption and the dust, and improving the transport efficiency of the equipment.

The utility model relates to the technical field of self-moving machine tails of belt conveyors of underground coal mine crossheading equipment, in particular to a coal shoveling plate assembly capable of automatically clearing coal. The device mainly comprises a coal shoveling plate, an upper hydraulic cylinder, a side hydraulic cylinder, a left connecting plate, a right connecting plate, a left coal cleaning plate and a right coal cleaning plate. The coal cleaning device is arranged on a tail end frame of the self-moving tail of the belt conveyor, and the left coal cleaning plate and the right coal cleaning plate do reciprocating motion by taking the hydraulic cylinder as power so as to clean coal slime scraped from a tail roller by a coal scraping plate. The utility model provides a coal shoveling plate assembly capable of automatically cleaning coal, which can completely replace a traditional coal cleaning plate which relies on manual coal cleaning, can reduce the labor intensity of underground coal mine workers, saves the labor cost, and improves the use performance of a self-moving tail of a belt conveyor. The device is simple in structure and smooth in reciprocating motion.

This invention relates to an anti-slip device for scraper conveyors, belonging to the field of scraper conveyors. This invention solves the technical problem of existing scraper conveyors, which use chain-connected anti-slip methods, easily sliding downwards along the coal seam's inclination during the pushing process, resulting in slippage and reduced production efficiency. A sleeve is fixedly installed on the lower left side of a fixed plate. Anti-slip spikes are slidably installed inside the sleeve. One end of a spring is connected to the right end face of the anti-slip spike, and the other end is connected to the fixed plate. The spring is in a compressed state and exerts a leftward elastic force on the anti-slip spike. A positioning port is provided at the top of the sleeve, and a positioning groove is provided at the top of the anti-slip spike. A positioning pin simultaneously passes through the positioning port and the positioning groove to fix the anti-slip spike. The fixed plate of the anti-slip mechanism is installed on the outer wall of the coal shovel side of the middle trough of the scraper conveyor. The anti-slip spikes are always pressed against the working face by the spring force, preventing slippage during the pushing process. This invention is used for scraper conveyors.

The present application relates to a kind of auxiliary loading mechanism of rocker arm of suspended machine body coal mining machine and suspended machine body coal mining machine, the auxiliary loading mechanism includes the machine body of coal mining machine, coal shovel plate, center shaft and torsion spring, the center shaft is along front and back direction and is passed through the lower end of the machine body left and right direction towards the side of rocker arm and the upper end of corresponding side coal shovel plate, the hinge of machine body and coal shovel plate is realized, the front and back ends of center shaft are detachably fixed on the machine body, at least two torsion springs are set on a center shaft, the two ends of torsion spring are respectively resisted on the machine body and coal shovel plate;The suspended machine body coal mining machine includes auxiliary loading mechanism and support skid shoe, the rear end of coal shovel plate covers the part of the side of support skid shoe from the outside of left and right direction.The present application can keep the effective contact of coal shovel plate and floor, improve loading effect, when not need loading, also can make coal shovel plate separate from floor, to ensure that the discharge of machine body under floating material and the passability of coal mining machine.
