Description
Technical Field
[0001] This utility model relates to the field of mining conveying technology, specifically a self-cleaning heavy-duty plate feeder. Background Technology
[0002] In recent years, with the widespread application of conveying equipment in industries such as coal, metallurgy, mining, power, and building materials, key equipment for short-distance continuous or intermittent conveying of large-capacity, high-density, sharp and rough materials (such as ores, limestone, and coal lumps) has become increasingly important. It consists of heavy-duty chain plates, a drive unit, a head wheel assembly, a tail tensioning device, and a frame, possessing strong load-bearing capacity and impact resistance. In existing technologies, during material conveying, especially powdery or small granular materials, plate feeders easily leak into the pit or foundation below the equipment through gaps between chain plates or between the chain plates and side plates. Manual cleaning requires machine shutdown, workers entering the pit for cleaning, resulting in high labor intensity, harsh working conditions, safety hazards, and reduced production efficiency. Some project sites install a small belt conveyor below the heavy-duty plate feeder for receiving and transferring materials. However, these are usually two independent systems, presenting problems such as large equipment layout space, high civil engineering costs, high investment and maintenance costs, and complex collaborative operation. To address the aforementioned problems, this invention aims to provide an integrated self-cleaning heavy-duty plate feeder that is compact in structure, requires no manual cleaning, can automatically and continuously handle material leakage, and reduces civil engineering and equipment costs. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning heavy-duty plate feeder, comprising a frame, a tail tensioning device provided at the left end of the upper surface of the frame, a driven shaft provided on the tail tensioning device, and a drive shaft provided at the right end of the upper surface of the tail tensioning device, with a chain plate provided between the drive shaft and the driven shaft, a belt conveyor provided at the lower end of the frame, the belt conveyor being located directly below the chain plate, and a drive unit for rotating the drive shaft being provided on one side of the frame, a receiving chute provided on the frame, the belt conveyor and the chain plate having opposite conveying directions, the receiving chute being located between the lower surface of the chain plate and the upper surface of the belt conveyor, the receiving chute guiding the broken material falling from the chain plate to the upper surface of the belt conveyor, and an infeed chute provided on the upper surface of the frame.
[0005] Furthermore, the drive unit includes a drive motor and a reducer mounted on one side of the frame. The output shaft end of the drive motor is connected to the input shaft end of the reducer via a coupling, and the output shaft end of the reducer is connected to the end of the drive shaft via a coupling. The rotation of the drive motor can drive the reducer to rotate, the rotation of the reducer can drive the drive shaft to rotate, and the rotation of the drive shaft can drive the chain plate to rotate. The chain plate can transport the raw materials inside the feed chute.
[0006] Furthermore, the receiving chute includes two guide plates fixed on the frame. The two guide plates are located on the front and rear sides inside the frame and have an inverted V-shape structure. The receiving chute can guide the broken material falling from the chain plate to the upper surface of the belt conveyor.
[0007] Furthermore, the tail tensioning device includes two sliding supports, and the frame is provided with two sliding grooves corresponding to the sliding supports. The sliding grooves are U-shaped, and the sliding supports are slidably connected to the corresponding sliding grooves. A screw is fixed on one side of each sliding support. The screw passes through the sliding groove of the frame, and an adjusting nut is provided at the end of the screw located outside the sliding groove of the frame. The driven shaft is set between the two sliding supports through bearings at both ends. By rotating the adjusting nut, the screw is moved, and by the movement of the screw, the sliding supports slide left and right. The sliding supports drive the driven shaft to move, thereby adjusting the tension of the chain plate.
[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: By rotating the adjusting nut, the screw moves; by the screw moving, the sliding support slides left and right; by the sliding support, the driven shaft moves, thereby adjusting the tension of the chain plate. By rotating the drive motor, the reducer rotates; by the reducer rotating, the drive shaft rotates; by the drive shaft rotating, the chain plate rotates. The chain plate conveys the raw materials inside the feed chute. The receiving chute guides the broken material falling from the chain plate to the upper surface of the belt conveyor. The belt conveyor then transports and collects the fallen broken material. After the chain plate stops conveying, the belt conveyor stops after a delay, thus ensuring that all fallen broken material is collected. This self-cleaning heavy-duty plate feeder has a compact structure, greatly saving equipment installation space, reducing the depth and complexity of civil engineering such as pits, reducing initial investment, realizing automatic and continuous collection and transfer of leaked material, completely avoiding manual cleaning, and improving production safety and efficiency.
