[0019] The forward section and the return section of the coal conveyor belt both pass through the belt window; The belt pressing assembly 3 is fixed between the two square hollow boxes 1-1 of the support frame and is used to press the return section 9 of the coal conveyor belt; The belt pressing assembly includes two side plates 3-1 arranged front and back, the two ends of the two side plates are respectively fixed on the square hollow box body on the corresponding side, four belt pressing rollers 3-2 are connected between the two side plates, and the four belt pressing rollers are distributed on the front and back sides in a group of two, four fixed shafts are fixed between the two side plates, and each fixed shaft is rotatably connected to a belt pressing roller, and a scraper plate 3-3 is fixed between the two groups of belt pressing rollers, and the scraper top of the scraper plate contacts the bottom surface of the return section of the coal conveyor belt; During operation, the return section of the coal conveyor belt passes through the belt pressing assembly, so that it limits the return section of the coal conveyor belt to prevent the return section of the coal conveyor belt from falling and making it difficult to scrape the material; The sticky coal on the return section of the coal conveyor belt can be effectively scraped off by the scraper plate; The receiving cone bucket 10 is fixed between the two square hollow boxes of the support frame and is used to receive the coal scraped off the return section of the coal conveyor belt; After the scraper scrapes off the sticky coal on the return section of the coal conveyor belt, it will fall into the receiving cone bucket for receiving the sticky coal; The material turning assembly 5 is fixed between the two square hollow boxes of the support frame and is used to convey and turn the coal received by the cone bucket to the process section 8 of the coal conveyor belt; The material turning assembly includes two driving rings 5-2 and four transmission shafts 5-10, each of the square hollow boxes has a driving ring, the driving ring is connected to the fixed ring plate through a connecting bearing 5-8, the outer wall of the driving ring has an outer gear ring 5-3, the inner wall has an inner gear ring 5-7, the four transmission shafts are distributed in parallel in a square shape, each of the transmission shafts is connected to the end wall of the square hollow box on the corresponding side through a bearing, sprockets 5-1 are fixed on both sides of each transmission shaft, and passive gears 5-9 are fixed at both ends of each transmission shaft, the passive gears are meshed with the inner gear rings of the driving rings on the corresponding sides, the sprockets on the same side of the four transmission shafts are driven by chains 5-6, so that the chains form a square rotating form, the two chains are directly opposite, and the outer chain plates corresponding to the two chains are fixed with fixed bucket rods 5-5, and the two fixed bucket rods are respectively fixed on both sides of the receiving hopper; After the sticky coal is received in the receiving cone bucket, the sticky coal will fall along the receiving cone bucket into the receiving hopper at the bottom of the square outlet. The turning component is constantly rotating. After the receiving hopper that receives the sticky coal moves to the top of the coal conveyor belt process section, the sticky coal inside will fall out. The fallen coal will fall back onto the coal conveyor belt process section along the guide plate, thus realizing the recovery of the sticky coal. The driving assembly 6 is fixed in the square hollow box at the front end / rear end of the supporting frame and is used to drive the turning assembly to rotate.

[0020] The driving assembly includes a driving motor 6-2, the output shaft of the driving motor is fixed to the driving shaft 6-3, the driving shaft is connected to the end faces of the two square hollow boxes through bearings, and two driving gears 6-1 are fixed on the driving shaft, and each of the driving gears is meshed with the outer gear ring of the driving ring on the corresponding side.

A driving gear is fixed on the driving shaft, and the driving gear is meshed with the outer gear ring on the driving ring, so that it drives the driving ring to rotate, and then drives the turning assembly to move.

[0022] The coal conveyor belt cleaning device described above has a receiving hopper of a parallelogram hopper body 5-4-2 structure, the height of the front and rear back plates 5-4-1 is greater than the height of the two side plates, and the side plates form an angle of 45° with the bottom surface.

[0023] By setting the receiving hopper so that the angle between the side plate and the bottom surface is 45 degrees, that is, P is 45 degrees, when the receiving hopper rotates to the vertical section of the chain under the drive of the chain, the side surface when it rotates to the bottom is tilted upward and forms an angle of 45 degrees with the horizontal plane, which can prevent the sticky coal in the receiving hopper from falling out.

[0024] The height of the two back plates is set to be greater than the height of the two side plates, the bottom of the receiving cone hopper is a square outlet, the height of the bottom of the square outlet is greater than the height of the top of the two side plates of the receiving hopper, and less than the height of the top of the two back plates of the receiving hopper; By setting this height, the bottom of the square outlet is located between the two back plates of the receiving hopper, preventing the sticky coal from falling out from between the square outlet and the back plate when it is discharged through the square outlet, thus ensuring the coal receiving effect; The receiving hopper is a parallelogram hopper structure, and the length of the horizontal plane on the top of its back plate is the distance between the centers of two adjacent outer chain plates of the chain; Such a distance setting allows the two adjacent receiving hoppers to maintain contact, so that when coal falls from the square outlet, it will not fall into the gap between the two receiving hoppers, ensuring the reception of the falling coal; In the coal conveyor belt cleaning device, two guide plates 7 are fixed between the two square hollow boxes. The two guide plates are symmetrically arranged and have closed lower ends.

[0025] Because the receiving hopper will move with the chain after receiving the coal, the opening of the receiving hopper will gradually face downward when transitioning from the vertical section of the chain to the horizontal section at the top of the chain. At this time, if a guide plate is not set, it is impossible to ensure that all the sticky coal will fall onto the process section of the coal conveyor belt. By setting the guide plate, the coal falling out of the receiving hopper will fall onto the guide plate, and under the guidance of the guide plate, all of it will fall to the process section of the coal conveyor belt.

[0026] In the coal conveyor belt cleaning device, the width of the belt passing window is smaller than the width of the two side plates of the belt pressing assembly, so that the two side plates of the belt pressing assembly can be smoothly fixed on the end wall of the square hollow box body.

[0027] Working principle: When in use, start the drive motor, the reduction motor of the drive motor, the drive motor drives the drive shaft to rotate, a drive gear is fixed on the drive shaft, the drive gear is meshed with the outer gear ring on the drive ring, so that it drives the drive ring to rotate, the inner gear ring of the drive ring is meshed with each passive gear, so that it drives the passive gear to rotate, so that the four transmission shafts rotate, each transmission shaft is fixed with a sprocket on both sides, the sprockets on the same side of the four transmission shafts are driven by chains, so that the chains form a square rotation form, the two chains are directly opposite, and the outer chain plates corresponding to the two chains are fixed with fixed bucket rods 5-5, two The fixed bucket rods are respectively fixed on both sides of the receiving hopper 5-4, so that the receiving hopper can move under the transmission of the chain. When the coal is stuck in the return section of the coal conveyor belt, it will be scraped off by the scraper plate, and the scraped coal will fall into the receiving cone bucket, and will be discharged through its square opening and fall into the receiving hopper at the bottom. The receiving hopper moves under the transmission of the chain, from the horizontal section to the vertical section, and then from the vertical section to the upper horizontal section. During the movement to the upper horizontal section, the opening of the receiving hopper will gradually face downward, and the coal inside it will fall out and fall onto the guide plate, and under the guidance of the guide plate, it will fall to the process section of the coal conveyor belt, thereby realizing the recovery of sticky coal.
