Fixed loading, a shock-absorbing spring is connected to the outside of the hydraulic rod, and the top of the shock-absorbing spring is connected to the fixed rod 204. The shock-absorbing spring is used to absorb and reduce the vibration and impact caused by uneven roads, so that the device is more stable during operation. The fixed rod 204 is connected to the wheel and supports the hydraulic rod and the shock-absorbing spring to stabilize the wheel and the entire device. At the same time, the hydraulic rod and the shock-absorbing spring reduce the impact of vibration and bumps on the trolley. The top of the traveling sports car 1 is fixedly connected to an equipment frame, and a coal collecting frame 201 is installed on the upper end of the equipment frame through a number of shock-absorbing devices 203. The coal collecting frame 201 is a rectangular opening frame. The coal collecting frame 201 is a structure for collecting and guiding coal. The inclined rectangular opening frame makes it easier to guide and concentrate coal during loading. The opening end of the coal collecting frame 201 is fixed A spray frame is fixedly connected to the spray frame, and a plurality of spray heads 202 are fixedly connected to the spray frame. The spray heads 202 are used to spray water mist to reduce dust generated when coal falls and improve the cleanliness and visibility of the underground working environment. Roller frames 4 are arranged on the front and rear sides of the fixed frame 3 for installing belt rollers. A second hydraulic rod is connected to the top of the fixed card 7, and the top of the second hydraulic rod is fixedly connected to the coal collecting frame 201. A shock-absorbing spring is fixedly connected to the outside, and the top of the shock-absorbing spring is fixedly connected to the coal collecting frame 201. A plurality of Φ12mm holes are evenly distributed on the coal collecting frame 201 for installing oblique coal collecting plates to provide controllable damping force to further reduce the vibration and bumps of the coal collecting frame 201. A crossbeam is fixedly connected to the middle of the left and right sides of the equipment frame for installing the coal collecting plates. The inclined coal collecting plate on the coal frame 201 is used to guide and collect the coal, making it easier to be collected in the coal collecting frame 201. At the same time, the length of the inclined coal collecting plate is set long, so that the internal space of the coal collecting plate is reduced. When the coal falls, most of it falls on the shock absorbing device 203 above and below the inclined coal collecting plate for buffering. The bottom end of the closed end of the coal collecting frame 201 is connected to a flat support hub 5 for installing a flexible belt, a combination of a hydraulic rod, a spring and a fixed rod 204, as well as the inclined setting of the coal collecting frame 201 and the design of the inclined coal collecting plate make the device more stable during operation, reduce the scattering of coal and damage to the device, and the setting of the sprinkler head 202 can effectively reduce the dust generated when the coal falls, improve the cleanliness of the working environment, and when the trolley passes through an uneven underground road,The hydraulic rod, the shock absorbing spring and the fixed rod 204, the fixed rod 204 rotates to bring out the connected hydraulic rod, and at the same time, the wheels of each trolley form an independent whole, so as to avoid the coal spilling due to the uneven road surface, reduce the impact of vibration and bumps, and maintain the stability of the trolley. The coal collecting frame 201 collects the coal and reduces the dust through the sprinkler head 202, and at the same time, the oblique coal collecting plate guides the coal into the coal collecting frame 201, and at the same time, a flexible belt is installed on the flat support hub 5 to collect the coal, and at the same time, the reserved coal roller frame 4 is installed with a belt support hub to support the belt.

[0025] The shock absorbing device 203 includes a sliding block 2201, a hydraulic push rod 2202, a connecting rod 2203, and a fixed frame 3. The connecting rod 2203 is used to fix the two fixed frames 3, integrate the shock absorbing device 203 into the structure of the fixed frame 3, and ensure that the shock absorbing device 203 can work effectively. A connecting rod 2203 is fixedly connected in the middle of the two fixed frames 3. A pair of sliding blocks 2201 are slidably connected on the connecting rod 2203. The sliding blocks 2201 are used to connect the hydraulic push rod 2202 and the connecting rod 2203, and at the same time provide additional shock absorbing function through the fixedly connected springs. Their sliding connection can adapt to vibrations and impacts under different conditions. Springs are fixedly arranged between the sliding blocks 2201. The top of the sliding block 2201 is hinged with a hydraulic push rod 2202, and the hydraulic push rod 2202 plays a stabilizing and shock-absorbing role.

The other end of the hydraulic push rod 2202 is hinged to the coal collecting frame 201, and a spring is fixedly connected to the hydraulic push rod 2202. A connecting block is connected between the coal collecting frame 201 and the hydraulic push rod 2202. The connecting block is arranged in a trapezoidal shape, and the connecting block is arranged parallel to the working surface of the sliding block 2201. A spring is fixedly connected to the hydraulic push rod 2202, and the other end of the spring is fixedly connected to the sliding block 2201. When the coal falls, the oblique coal collecting plate on the coal collecting frame 201 is impacted first, and the coal collecting frame 201 is impacted at the same time. Then the hydraulic push rod 2202 rotates, and the sliding block 2201 slides on the connecting rod 2203. At the same time, the spring between them reduces the impact vibration and provides shock absorption. At the same time, since the device is installed between the fixed frame 3, the fixed frame 3 plays a limiting role, so that the sliding block 2201 will not slide beyond the range of the connecting rod 2203.
