[0092] To achieve the above-mentioned technical effects, such as Figure 1 As shown, the chain structure 53 includes:

[0093] A first double-row conveyor roller chain 28 is installed above the first side plate 1, the second side plate 2, and the side plate connecting plate 3 of the frame 50. The first double-row conveyor roller chain 28 can withstand greater loads, transmit greater power, and improve conveying capacity.

[0113] To achieve the above-mentioned technical effects, such as Figure 1As shown, several metal adjusting feet 30 are fixedly connected to the first side plate 1 and the second side plate 2. These metal adjusting feet 30 provide a solid support foundation for the entire equipment, ensuring its stability. By adjusting the height of the metal adjusting feet 30, the equipment can be kept in a horizontal position to adapt to complex terrain and facilitate easy movement and installation. The metal adjusting feet 30 can also reduce wear and tear between the equipment and the ground during operation, extending the equipment's service life.

Through one end of the lower connecting rod 47 of the transmission sprocket system 7, the second motor end sprocket 32 ​​and the first double sprocket 36 of the chain structure 53 rotate coaxially, thereby driving the chain link. The first double-row conveyor roller chain 28 of the chain structure 53 operates. It first passes through the fourth end redirecting sprocket 41 of the redirecting device 52, then runs along the third end redirecting sprocket 40 of the redirecting device 52, passing through the second tensioning pulley 34, the second motor end sprocket 32, and the first tensioning pulley 33 of the chain structure 53, returning to the first motor end sprocket 11 of the chain structure, forming a closed loop. Through the connection of the other end of the lower connecting rod 47 of the transmission sprocket system 7 and the other end of the upper connecting rod 17 of the guide device 51, the second double-row conveyor roller chain 39 of the chain structure 53 moves in the same direction and at the same speed as the first double-row conveyor roller chain 28, reducing energy loss during power transmission and improving power transmission efficiency. The fixed connection method avoids relative swaying between the motor and reducer 26 and the first motor end sprocket 11, ensuring the accuracy and stability of the chain conveying, enabling materials to be conveyed at a predetermined speed and position, reducing noise and wear caused by vibration, and extending the service life of the equipment.
