Description

Technical Field

[0001] This utility model relates to the field of coal block sorting technology, specifically a large coal block sorting structure for coal block belt conveyor. Background Technology

[0002] Coal block belt conveyors are continuous conveying equipment, mainly composed of conveyor belts, drive units, idler rollers, tensioning devices, and frames. They achieve horizontal or inclined conveying of coal blocks through the cyclical movement of the circular conveyor belt. Large coal blocks are prone to clogging at belt conveyor transfer points, chutes, or crusher inlets, leading to equipment overload and shutdown. Statistics show that in unsorted coal flows, blockage accidents caused by large coal blocks account for more than 40% of belt system failures. Therefore, coal blocks need to be sorted during transportation to reduce the failure rate of the conveyor.

[0003] In the prior art, a coal block sorting device disclosed in patent publication number "CN221493310U" relates to the field of coal block sorting technology. It includes a sorting frame with a conveyor belt structure mounted on it. Three support frames are horizontally mounted on the sorting frame, and two power shafts are mounted on the three support frames via bearings. This coal block sorting device, through the support of several sorting rods by two power rods, allows the sorting rods to rotate counterclockwise on the power shafts under the drive of a motor. This process removes coal blocks from the coal conveyed on the conveyor belt structure, which are then discharged through a collection box. The remaining coal particles continue to be conveyed along the conveyor belt structure, thus achieving coal sorting. Furthermore, by utilizing the different spacing between the sorting rods on both sides of the power shaft, coal blocks of different sizes can be sorted, meeting the coal sorting requirements.

[0004] However, the existing technology still has significant shortcomings. Traditional sorting devices and belt conveyors are arranged separately, which means that coal blocks need to be transferred multiple times to complete the sorting operation. The sorting process relies heavily on fixed grid screens or manual picking, resulting in insufficient sorting accuracy. At the same time, qualified coal blocks after sorting need to be transported to the belt conveyor again by transfer equipment, while large coal blocks that do not meet the standards need to be collected manually and transported to independent crushing equipment for processing. The entire process suffers from obvious operational interruptions and low efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a large coal block sorting structure for coal block belt conveyor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a large coal block sorting structure for coal block belt conveying, including a conveyor, a feeding device on one side of the conveyor, the feeding device including a feeding frame, a feeding belt installed inside the feeding frame, a sorting mechanism on the top of the conveyor, the sorting mechanism including a sorting frame, a sorting channel arrayed through the bottom surface of the sorting frame, a baffle plate at the end of the sorting frame, a rotating rod installed on the front of the baffle plate, a crushing assembly installed on the other side of the conveyor, the crushing assembly including a crushing box, a crushing cylinder installed inside the crushing box, and a support platform on the bottom surface of the crushing cylinder.

[0007] As can be seen, in the above technical solution, the seamless connection between the feeding belt and the sorting frame ensures a continuous and stable supply of coal blocks. The inclined sorting frame uses gravity to allow the coal blocks to slide down naturally. Combined with the multi-group sorting channels, it realizes rapid grading and screening of coal blocks, ensuring sorting accuracy. Moreover, the structure is simple and the cost is low. Qualified coal blocks directly enter the conveyor system to complete the transfer. For coal blocks that do not meet the standards, they are automatically intercepted by the blocking device. After opening, the coal blocks can slide down to the crushing station for direct crushing.

[0008] Preferably, the sorting frame is bolted to the top part of the feeding frame, and the sorting frame is located near the top of the feeding belt.

[0009] As can be seen, in the above technical solution, the feeding frame and the sorting frame are fixed, making the feeding and sorting parts an integrated unit, and the seamless connection between the feeding belt and the sorting frame ensures a continuous and stable supply of coal blocks.

[0010] Preferably, the sorting channel corresponds to the top surface of the conveyor belt, and the sorted coal blocks fall through the sorting channel to the conveyor belt.

[0011] As can be seen, in the above technical solution, qualified coal blocks after sorting can fall directly from the sorting channel onto the conveyor below, and the qualified coal blocks can be transported directly.

[0012] Preferably, the front of the barrier plate is screwed with a connector, and the connector is fixed to the surface of the rotating rod, and a rotating component is installed at one end of the rotating rod.

[0013] As can be seen, in the above technical solution, the partition plate is connected to the rotating rod via a connector, and the rotating rod is driven to rotate by a rotating component.

[0014] Preferably, the baffle plate is located at the inlet of the crushing chamber, and the baffle plate can rotate between the inlet of the crushing chamber and the end of the sorting frame.

[0015] As can be seen, in the above technical solution, the baffle plate can be rotated upwards and opened, so that there is no obstruction between the inlet of the crushing box and the end of the sorting frame, thereby allowing the blocked coal block to continue to slide along the inclined surface and enter the crushing box.

[0016] Preferably, the support platform is triangular, and the inclined surface of the support platform is used to accelerate the discharge speed of coal blocks, and the top of the support platform has rounded corners.

[0017] As can be seen, in the above technical solution, the support platform is triangular, and the coal blocks slide down quickly along the inclined direction of the support platform during discharge, realizing centralized and rapid recovery of the crushed coal blocks. The triangular support platform optimizes the coal flow distribution and greatly improves the unloading speed.

[0018] Preferably, the bottom of the support platform is equipped with a hydraulic cylinder, and the front and back of the crushing box are respectively provided with discharge ports.

[0019] As can be seen, in the above technical solution, the hydraulic cylinder can control the movement of the support platform to fall or rise, so that the support body can move to the discharge port to quickly complete the discharge of coal blocks, or move above it to wait for the coal blocks to accumulate to a specified weight before being discharged and recycled together.

[0020] Compared with the prior art, the beneficial effects of this utility model are: The integrated design of multi-component sorting devices and belt conveyors enables efficient and coordinated operation of coal block sorting, conveying, and crushing. The seamless connection between the feeding belt and the sorting frame ensures a continuous and stable supply of coal blocks. The inclined sorting frame utilizes gravity to allow coal blocks to slide naturally, and the multi-component sorting channels enable rapid grading and screening of coal blocks, ensuring sorting accuracy. The structure is simple and low-cost. Qualified coal blocks directly enter the conveyor system for transfer, greatly simplifying the process. The integrated design of the belt conveyor and sorting device not only saves equipment floor space but also forms a closed loop for coal flow processing, allowing sorted coal blocks to immediately enter the next process, avoiding the material accumulation and secondary transfer problems common in traditional systems. For substandard coal blocks, an automatic interception device is used. After opening, the coal blocks can slide to the crushing station. The crushed coal blocks are weighed and centrally discharged via a weighing platform, significantly reducing manual operation. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: Example 1: A large coal block sorting structure for belt conveyor: It includes a conveyor 1, and the sorting device of the conveyor 1 includes a feeding device 2, a sorting mechanism 3, and a crushing component 8. Multiple sorting devices are integrated with the belt conveyor 1. The number of sorting devices can be increased as needed, allowing multiple sorting devices to work simultaneously to sort coal blocks by size, greatly improving the efficiency of coal block sorting. The feeding device 2 includes a feeding frame 21, inside which a feeding belt 22 is installed. The top of the conveyor 1 is equipped with... A sorting mechanism 3 is provided, comprising a sorting frame 31. The sorting frame 31 is bolted to the top of the feeding frame 21 and is located near the top of the feeding belt 22. A sorting channel 32 is arrayed through the bottom surface of the sorting frame 31, and the sorting channel 32 corresponds to the top surface of the conveyor belt 1. The sorted coal blocks fall through the sorting channel 32 to the conveyor belt 1. The feeding belt 22 in the feeding device 2 can transfer the coal blocks to be sorted into the sorting frame 31. 22 includes a drive motor, enabling the belt to rotate on the shaft surface. The feeding belt 22 also includes a feeding baffle to prevent coal blocks from slipping during feeding. The sorting frame 31 is designed with an incline, allowing coal blocks to slide down the inclined surface after falling. During this process, appropriately sized coal blocks are discharged through the sorting channel 32 on the sorting frame 31 to the conveyor 1 below, directly transporting the appropriately sized coal blocks. This improves equipment efficiency and reduces manual intervention. The coal blocks are fed via the feeding belt 22... The coal is automatically transferred to the sorting frame 31 without any intermediate transfer links. The inclined design of the sorting frame 31, combined with the weight of the coal, allows for automatic grading of the coal using the gravity separation principle. Qualified coal blocks fall directly into the conveyor 1 below through the sorting channel 32, achieving simultaneous sorting and conveying operations without any manual intervention. Since large coal blocks are prone to getting stuck at the conveyor belt transfer point, chute, or crusher inlet, causing equipment overload and shutdown, large coal blocks need to be sorted before transportation to avoid direct conveyor belt transport.

[0025] A baffle plate 4 is provided at the end of the sorting frame 31. A crushing assembly 8 is installed on the other side of the conveyor 1. The crushing assembly 8 includes a crushing box 81. The baffle plate 4 is located at the inlet of the crushing box 81 and can rotate between the inlet of the crushing box 81 and the end of the sorting frame 31. Some coal blocks that are not sorted or unqualified are blocked by the baffle plate 4. After the blocked coal blocks reach a fixed length, the baffle plate 4 can be rotated open, allowing the coal blocks to slide down into the crushing box 81 along the inclined direction. A crushing cylinder 82 is installed inside the crushing box 81. A support platform 83 is provided on the bottom surface of the crushing cylinder 82. The support platform 83 is triangular, and the inclined surface of the support platform 83 is used to accelerate the discharge speed of the coal blocks. The top of the support platform 83 has rounded corners, and a hydraulic cylinder 84 is provided at the bottom of the support platform 83. Discharge ports 85 are opened on the front and back of the crushing box 81, respectively. The two crushing cylinders 82 rotate simultaneously to crush the coal blocks that have passed through the crushing frame 31. The coal blocks are crushed by a motor-driven crushing cylinder 82 to crush unsorted coal blocks to meet size requirements. The crushed coal blocks are piled on a triangular support platform 83, allowing the crushed coal blocks to accumulate on both sides. A weight sensor can be installed on the support platform to monitor the weight of the crushed coal blocks. When the set weight value is reached, a buzzer will remind the staff to prepare a recycling container and place it in the designated position in advance. At this time, the support platform 83 descends to the discharge port 85, and the hydraulic cylinder 84 controls the movement of the support platform 83 to fall or rise. The coal blocks slide down quickly along the tilt direction of the support platform 83, achieving centralized and rapid recycling of the crushed coal blocks. The weight sensor enables quantitative recycling, avoiding overloading or empty loading. The triangular support platform 83 optimizes the coal flow distribution, greatly improving the unloading speed. The entire process is automated, reducing labor costs and operational risks.

[0026] A rotating rod 5 is installed on the front of the baffle plate 4. A connector 6 is screwed to the front of the baffle plate 4 and the connector 6 is fixed to the surface of the rotating rod 5. A rotating part 7 is installed at one end of the rotating rod 5. The baffle plate 4 is opened and closed by rotating the rotating rod 5. When the intercepted coal blocks reach the set amount, it automatically flips and guides the unsorted coal blocks to the crushing box 81. This process utilizes the weight of the coal blocks to slide down without additional power. To ensure the correct opening time, a vision camera can be added at the sorting frame 31 to visually detect the length of the intercepted coal blocks. When the specified length is reached, the rotating rod 5 can be controlled to open the baffle plate 4. The rotating rod 5 is mainly connected and fixed to the rotating plate through the connector 6. When the rotating part 7 is equivalent to a rotary motor, it can drive the rotating rod 5 and the connected baffle plate 4 to rotate together, opening the inlet end of the crushing box 81. Working Principle: A multi-group sorting device is integrated with a belt conveyor 1, greatly improving the efficiency of coal block sorting. The feeding belt 22 in the feeding device 2 transfers the coal blocks to be sorted into the sorting frame 31. The sorting frame 31 is designed with an incline; after falling, the coal blocks slide down the inclined surface. During this process, the qualified coal blocks are discharged through the sorting channel 32 on the sorting frame 31 to the conveyor 1 below, directly transporting the qualified coal blocks. This improves the equipment's efficiency and reduces manual intervention. Some missed coal blocks and unqualified coal blocks are blocked by the baffle plate 4. The blocked coal blocks reach a fixed length... After the initial tilt, the baffle plate 4 can be rotated open, allowing the coal blocks to slide down into the crushing box 81 along the tilt direction. The unsorted coal blocks are crushed to meet the size requirements. The crushed coal blocks accumulate on the support platform 83. Since the support platform 83 is triangular, the crushed coal blocks can accumulate on both sides. The support platform can be equipped with a weight sensor to monitor the weight of the crushed coal blocks. When the set weight value is reached, it can remind the staff to prepare the recycling container and place it in the designated position in advance. At this time, the support platform 83 descends to the position of the discharge port 85, and the coal blocks slide down quickly along the tilt direction of the support platform 83, realizing centralized and rapid recycling of the crushed coal blocks.
