Description

Technical Field

[0001] This utility model relates to the field of spiral material conveyors, and more particularly to a spiral belt conveyor that prevents material spillage. Background Technology

[0002] In the field of material conveying, spiral conveyor equipment faces multi-dimensional technical challenges: traditional chain spiral conveyors are prone to leakage of materials with a particle size of less than 3mm due to the gap between the chain links, and single-motor drive can only transmit in one direction. When reverse material transmission is required, it cannot meet the flexible reversal requirements of the production line. The adjustable gap design of chain conveyors is costly and complex to maintain. Traditional belt spiral conveyors lack anti-spillage structures, and the fixed baffles of belt conveyors are difficult to solve the problem of spillage caused by belt misalignment. During spiral motion, materials are easily spilled from the edge of the belt due to centrifugal force and inertia, especially at track bends where the spillage rate is as high as 20%. At the same time, the belt is prone to wrinkles due to the stretching effect of the spiral track when it is taut for a long time, resulting in a decrease in conveying efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a spiral belt conveyor that prevents material spillage, in order to solve the problems mentioned in the background art.

[0005] As a preferred embodiment of this utility model, a plurality of guide rollers are distributed on the spiral track, an auxiliary wheel is provided on one side of the guide rollers, the auxiliary wheels are provided on the outer side of the spiral guide rail, and a T-shaped groove is provided on the inner side of the spiral track.

[0006] As a preferred embodiment of this utility model, the anti-spillage protection structure includes an outward protective plate, which is arranged along the outer side of the spiral track, and a turning protective plate is provided at the bottom end of the spiral track near the inner side of the spiral track.

[0007] In a preferred embodiment of this utility model, the belt conveyor mechanism includes a motor, which is mounted on a base plate. The output end of the motor has a transmission rod, and the transmission rod has a transmission wheel. A transmission wheel has a second transmission wheel on one side of the transmission wheel, and a transmission rod has a second transmission wheel. A transmission belt is fitted onto the transmission wheel and the transmission wheel.

A support frame is mounted on the base plate. A steering roller is movably mounted in the middle of the support frame, and a tensioning roller is movably mounted at the top of the support frame. A conveyor belt is installed inside the spiral track. The conveyor belt loops around the first transmission roller, the spiral track, the second transmission roller, the tensioning roller, and the steering roller to form a cyclic transmission path. One side of the conveyor belt is in contact with an auxiliary wheel.

[0008] As a preferred embodiment of this utility model, one side of the conveyor belt is provided with a T-shaped toughness belt, which cooperates with the T-shaped groove.

[0012] 2. By replacing the chain with belt drive, seamless and stable transmission of small particles is achieved, reducing the leakage rate from 10% to ≤2%.

It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0022] This utility model provides a technical solution: a spiral belt conveyor that prevents material spillage, such as... Figure 1 , Figure 2 As shown, it includes a base plate 1, a support column 101 on the base plate 1, several support plates 102 on the support column 101, a spiral track 103 spirally surrounding the support column 101, several support plates 102 connected to the bottom of the spiral track 103, a spillage protection structure 3 on the spiral track 103, and a belt conveyor mechanism 4 inside the spiral track 103.

[0023] like Figure 1 , Figure 2 , Figure 4 As shown, a number of guide rollers 2 are distributed on the spiral track 103. An auxiliary wheel 201 is provided on one side of the guide roller 2. The auxiliary wheels 201 are located on the outer side of the spiral track 103. A T-shaped groove 202 is provided on the inner side of the spiral track 103.

[0024] like Figure 2As shown, the anti-spillage protection structure 3 includes an outward protective plate 301, which is set along the outer side of the spiral track 103, and a turning protective plate 302 is provided at the bottom end of the spiral track 103 near the inner side of the spiral track 103.

[0025] like Figure 3 , Figure 5 , Figure 6 As shown, the belt conveyor mechanism 4 includes a motor 401 mounted on a base plate 1. A transmission rod 402 is located at the output end of the motor 401. A transmission wheel 403 is mounted on the transmission rod 402. A transmission wheel 405 is located on one side of the transmission wheel 403. A transmission rod 406 is mounted on the transmission wheel 405. A transmission belt 404 is fitted onto the transmission wheel 403 and the transmission wheel 405. A transmission roller 407 is connected to the other end of the transmission rod 406. The transmission roller 407 is movably mounted at the bottom end of a spiral track 103. A motor 408 is located on one side of the top end of the spiral track 103. The output end of 8 is provided with a transmission rod 3 409, and the other end of the transmission rod 3 409 is connected to a transmission roller 2 410. The transmission roller 2 410 is movably set at the top of the spiral track 103. The base plate 1 is provided with a support frame 411. The middle of the support frame 411 is movably set with a steering roller 412. The top of the support frame 411 is movably set with a tensioning wheel 413. The spiral track 103 is provided with a conveyor belt 414. The conveyor belt 414 forms a circulating transmission path by passing through the transmission roller 1 407, the spiral track 103, the transmission roller 2 410, the tensioning wheel 413, and the steering roller 412. One side of the conveyor belt 414 is in contact with the auxiliary wheel 201.

[0026] like Figure 4 As shown, one side of the conveyor belt 414 is provided with a T-shaped flexible belt 415, which cooperates with the T-shaped groove 202.

[0028] In practice, the user transports the equipment to the working position using the traction device 501. After adjusting the moving wheels 502 to stabilize the equipment, the material conveying operation can begin. When conveying materials downwards, motor 401 is the main drive, and its output shaft drives transmission rod 402 to rotate, driving transmission wheel 403 to drive transmission wheel 405 via transmission belt 404. Through transmission rod 406, transmission roller 407 becomes the active roller, driving the conveyor belt 414 to run downwards along the spiral track 104. At the same time, motor 408 drives transmission roller 410 as a driven roller via transmission rod 409 to provide auxiliary pulling force. At this time, guide roller 201 supports the inner side of the belt, auxiliary wheel 202 fits against the outer T-shaped toughness strip 415 of the belt and forms a guiding constraint through the T-shaped groove 202. Outward protective plate 301 prevents materials from being thrown out due to centrifugal force, and turning protective plate 302 prevents materials from being thrown inwards at the bottom of the track due to turning. When conveying materials upward, motor 2 408 is the main drive, which drives transmission roller 2 410 to move the belt upward through transmission rod 3 409. Motor 1 401 assists in driving transmission roller 1 407 to increase belt tension. Tensioner 413 adjusts belt tension, steering roller 412 changes belt return direction, outward protective plate 301 counteracts material lateral slippage force, and turning protective plate 302 assists in guiding material smoothly into the rising section. Guide roller 201 and auxiliary wheel 202 ensure stable belt operation, so that material is smoothly conveyed from the bottom to the top with the belt.
