Description

Technical Field

[0001] This utility model relates to the field of coal conveying technology, and in particular to a material drop position adjustment device and a stacker-reclaimer. Background Technology

[0002] A stacker-reclaimer is a device that can deliver coal into and store it in a coal yard and also retrieve coal from the coal yard. Due to the variety of coal types and their different specific gravities during stacking and unloading, the changing drop point during the stacking and unloading process can cause the conveyor belt to deviate from its designated path, leading to increased friction between the conveyor belt and the frame or other components, and accelerating belt wear.

[0003] To change the material drop position, an adjustment device (publication number CN216735985U) has been developed. The seasoning plate is installed below the chute via a rotating shaft and lifting lugs. The base is welded to a platform outside the chute. The screw is rotatably connected to the rear plate of the seasoning plate via the base. Rotating the screw can drive the seasoning plate to move back and forth, adjusting the tilt angle of the seasoning plate. By changing the tilt angle of the seasoning plate, the drop point of the material on the belt can be adjusted, thereby achieving the purpose of adjusting belt misalignment.

[0004] Existing adjustment devices for changing the material feeding position have a material feeding plate and a screw connected by a connecting plate and a pin. Although the angle of the material feeding plate can be adjusted, the rotation angle of the baffle is limited because the pin needs to rotate in the mounting hole on the connecting plate and the screw itself is limited. Large angle adjustments are not possible, and high machining accuracy is required. In addition, the pin bears a large load or wears out over a long period of time, requiring regular maintenance or replacement, which increases maintenance costs. Utility Model Content

[0005] To address the technical problems of existing adjustment devices for changing the material dropping position, which have limited adjustment of the material plate angle, poor adaptability, and high processing accuracy requirements, this utility model provides a material dropping position adjustment device and a stacker-reclaimer.

[0006] The technical solution of this utility model is as follows:

[0007] This utility model provides a material discharge position adjustment device, including an adjustment plate rotatably disposed at the outlet of the guide chute, a slide groove fixedly provided on the rear plate surface of the adjustment plate, a slider slidably disposed in the slide groove, an adjustment rod movably connected to the slider via a universal joint assembly, and a fixed bracket threadedly connected to the adjustment rod. The fixed bracket is fixedly disposed at the outlet of the guide chute. Through the cooperation between the slider, the slide groove and the universal joint assembly, the overall adaptability is stronger, and it can adapt to the adjustment needs of different angles and positions. Moreover, the contact area between the slider and the slide groove is large, and friction can be reduced through lubrication, eliminating the need for frequent disassembly and maintenance. Compared with the method of connecting the adjustment plate and the adjustment rod through a rotating shaft, it has a lower wear rate and lower processing precision requirements.

[0008] Preferably, the slide is set vertically to serve as a guide and support, ensuring the stability and controllability of the adjustment plate when adjusting the angle.

[0009] Preferably, the outer wall of the adjusting rod is provided with external threads, the fixed bracket is provided with threaded holes, and a lock nut is threadedly connected to the adjusting rod. The threaded connection between the adjusting rod and the fixed bracket facilitates the adjustment of the position of the adjusting rod. The lock nut can lock the adjusting rod and prevent the adjusting rod from loosening due to the impact and vibration between the material and the adjusting plate during operation.

[0010] Preferably, a handle is fixed to the end of the adjusting rod, which makes it easier to rotate the adjusting rod.

[0011] Preferably, a protective plate is detachably connected to the front panel of the adjusting plate to protect the adjusting plate from direct contact or collision with the material. When the protective plate is damaged, it can be replaced, effectively reducing maintenance costs.

[0012] Preferably, the protective plate is fixedly provided with a flange on its periphery. The flange covers the adjustment plate around its perimeter, which not only provides comprehensive protection for the adjustment plate, but also helps to improve the installation firmness of the protective plate by utilizing the limiting effect between the flange and the adjustment plate.

[0013] Preferably, the universal joint assembly includes a ball head, a connecting rod, a fixed seat, and a pressure cap. The fixed seat is fixedly mounted on the slider, and the ball head is fixedly connected to the adjusting rod through the connecting rod. The fixed seat and the pressure cap are detachably connected. The ball head is set in the spherical space formed by the fixed seat and the pressure cap, which reduces damage, eliminates the need for frequent maintenance, and provides higher positioning accuracy.

[0014] This utility model provides a stacker-reclaimer, including a cantilever with a belt, a stacker-reclaimer mechanism and a hopper at the end of the cantilever, a guide chute at the bottom of the hopper, and a material drop position adjustment device at the outlet of the guide chute to adjust the material drop position. This solves the problem of material belt deviation caused by changes in the drop point during stacking and unloading due to different material specific gravities. It also reduces basic investment caused by equipment defects, reduces the operation time of personnel adjustment, improves operation efficiency, and makes the adjustment process more intuitive, reducing repetitive adjustments due to unsuitable adjustments.

[0015] As can be seen from the above technical solutions, the advantages of this utility model are:

[0016] 1. The rear plate of the adjusting plate is fixedly provided with a slide groove, and a slider is slidably provided in the slide groove. The adjusting rod is movably connected through the universal joint head assembly. Through the cooperation between the slider, the slide groove and the universal joint head assembly, the overall adaptability is stronger and can adapt to the adjustment needs of different angles and positions. The contact area between the slider and the slide groove is large, and friction can be reduced by lubrication. It does not require frequent disassembly and maintenance. Compared with the method of connecting the adjusting plate and the adjusting rod through the rotation of the shaft, it has a lower wear rate and lower processing precision requirements.

[0017] 2. A protective plate is detachably connected to the front panel of the adjusting plate to protect the adjusting plate and prevent it from directly contacting or colliding with materials. When the protective plate is damaged, it can be replaced, effectively reducing maintenance costs. The protective plate is fixedly provided with flanges on its periphery, which cover the adjusting plate and not only provide comprehensive protection for the adjusting plate, but also help improve the installation firmness of the protective plate by using the limiting effect between the flanges and the adjusting plate.

[0018] 3. The adjusting rod is connected to the universal ball joint assembly, slider and slide groove. The slider, as an intermediate medium, can reduce the direct contact between the ball end and the slide groove, thereby reducing frictional resistance and making the sliding smoother. The wear between the ball end and the slide groove is reduced, extending the service life. Due to the smooth sliding and low wear, precise adjustment can be achieved more easily.

[0025] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0026] Example 1

[0027] In a typical embodiment of this utility model, such as Figure 1 As shown, a material dropping position adjustment device is proposed, including: an adjustment plate 1, an adjustment rod 2, a fixed bracket 3, a slide 5, a universal joint head assembly 6, and a slider 7. The adjustment plate 1 is rotatably mounted at the outlet of the guide chute 10 via a connecting shaft 8, which is a hinge structure. The front plate surface of the adjustment plate 1 is used to contact the material to guide it, and the rear plate surface of the adjustment plate 1 is used to connect the adjustment rod 2. The adjustment rod 2 is installed at the outlet of the guide chute 10 via the fixed bracket 3, so that the adjustment plate 1 can be driven to rotate around the axis to change the angle of the adjustment plate 1.

[0028] The fixed bracket 3 is fixedly installed at the outlet of the guide trough 10 by welding, bolt connection or other means. The fixed bracket 3 is provided with threaded holes. The adjusting rod 2 is a screw structure. The outer wall of the adjusting rod 2 is provided with external threads. The adjusting rod 2 is connected to the threaded hole on the fixed bracket 3 by threaded connection. One end of the adjusting rod 2 is fixedly provided with a handle 4 to facilitate the rotation of the adjusting rod 2. The other end of the adjusting rod 2 is connected to the adjusting plate 1 through the universal joint head assembly 6, the slider 7 and the slide groove 5.

[0029] like Figure 1 , Figure 3 As shown (where, for ease of showing the position of the adjusting lever ball head), Figure 1 (The slider 7, fixed seat, and other structures are not shown in the figure). The rear plate surface of the adjusting plate 1 is fixedly provided with a sliding groove 5. The sliding groove 5 is set vertically, and the slider 7 is slidably set in the sliding groove 5. One end of the universal joint head assembly 6 is fixedly connected to the slider 7, and the other end is fixedly connected to the end of the adjusting rod 2. This allows the included angle between the adjusting rod 2 and the adjusting plate 1 to be changed as needed, reducing the limitation of the adjusting rod 2 on the angle adjustment of the adjusting plate 1 and effectively expanding the angle adjustment range of the adjusting plate 1.

[0030] In this embodiment, the universal joint assembly 6 is a universal ball joint structure, specifically as follows: Figure 3 As shown, the universal joint assembly 6 includes a ball head, a connecting rod, a fixed seat, and a pressure cap. The fixed seat is fixedly installed on the slider 7 by bolts. The ball head is fixedly connected to the adjusting rod 2 by the connecting rod. The fixed seat and the pressure cap are detachably connected. The ball head is set in the spherical space formed by the fixed seat and the pressure cap. Compared with directly sliding the end of the adjusting rod 2 in the groove 5, the slider 7, as an intermediate medium, can reduce the direct contact between the spherical end and the groove 5, thereby reducing frictional resistance and making the sliding smoother. The wear between the spherical end and the groove 5 is reduced, extending the service life. Due to the smooth sliding and low wear, precise adjustment can be achieved more easily. A self-lubricating pad is also provided between the fixed seat and the ball head to reduce the wear between the ball head and the fixed seat.

[0031] A guide groove is provided on the side wall of the slide 5 along its length direction, and a guide protrusion is fixed on the side wall of the slider 7. The slider 7 restricts its position relative to the slide 5 by cooperating with the guide protrusion and the guide groove, so as to prevent the slider 7 from coming out of the slide 5.

[0032] Through the cooperation between slider 7, slide groove 5 and universal joint head assembly 6, the overall adaptability is stronger, which can adapt to the adjustment needs of different angles and positions. The contact area between slider 7 and slide groove 5 is large, and friction can be reduced through lubrication. It does not require frequent disassembly and maintenance. Compared with the method of connecting adjustment plate 1 and adjustment rod 2 by rotating shaft, it has a lower wear rate and lower processing precision requirements.

[0033] The adjusting rod 2 is also threaded with a lock nut 9, which is used to lock the adjusting rod 2 to prevent it from loosening due to the impact and vibration between the material and the adjusting plate 1 during operation.

[0034] The adjusting plate 1 has several bolt holes. The front plate of the adjusting plate 1 is connected to the protective plate 11 by bolts. The protective plate 11 protects the adjusting plate 1 and prevents the adjusting plate 1 from directly contacting or colliding with the material. When the protective plate 11 is damaged, it can be replaced, which effectively reduces maintenance costs.

[0035] like Figure 2As shown, the protective plate 11 is fixedly provided with flanges on its periphery. The flanges form a space for installing the adjustment plate 1. In actual use, the protective plate 11 is fastened to the front plate surface of the adjustment plate 1, and the flanges around the protective plate 11 cover the adjustment plate 1 to provide comprehensive protection for the adjustment plate 1. At the same time, the limiting effect between the flanges and the adjustment plate 1 can be used to help improve the installation firmness of the protective plate 11.

[0036] The specific working principle is as follows: By rotating the adjusting rod 2 through the handle 4, the adjusting rod 2 moves axially, which in turn pushes the adjusting plate 1 to rotate around its connecting shaft 8, thereby changing the tilt angle of the adjusting plate 1. When the adjusting plate 1 is pushed by the adjusting rod 2, the adjusting rod 2 drives the slider 7 to move along the slide groove 5 through the universal joint head assembly 6. At the same time, the slider 7 pushes the adjusting plate 1 to move. Through the cooperation between the slider 7, the slide groove 5 and the universal joint head assembly 6, the adjusting plate 1 can adapt to the adjustment requirements of different angles and positions, effectively expanding the angle adjustment range of the adjusting plate 1. When the adjusting plate 1 is adjusted to the position, the locking nut 9 is tightened to lock the position of the adjusting rod 2.

[0037] Example 2

[0038] In another typical embodiment of this utility model, a stacker-reclaimer is provided, comprising: a cantilever with a belt, a stacker-reclaimer mechanism, a hopper, a guide chute 10, and a material drop position adjustment device. One end of the cantilever is fixedly connected to the main body of the stacker-reclaimer, and the other end of the cantilever extends outward. The belt on the cantilever is used for material conveying. The stacker-reclaimer mechanism is installed at the end of the cantilever (i.e., the end of the cantilever away from the main body). The stacker-reclaimer mechanism realizes the stacking and reclaiming of materials through rotation, lifting, and other actions. The stacker-reclaimer mechanism can be a bucket wheel type, scraper type, etc. The hopper is installed at the end of the cantilever and is connected to the cantilever and the stacker-reclaimer mechanism. The lower part of the hopper is located at... At the upper part of the cantilever belt, the upper opening of the funnel is connected to the stacking and reclaiming mechanism. The guide chute 10 is fixedly set below the funnel to concentrate the material falling from the funnel to the middle of the belt before reaching the belt speed, preventing the material from accumulating on one side of the belt and causing the belt to run off-center. The material dropping position adjustment device is installed at the outlet of the guide chute 10 to adjust the material dropping position, solving the problem of material dropping off the cantilever belt due to the change of the dropping point during the stacking and unloading process caused by the different specific gravity of the material. It also reduces the basic investment caused by the equipment itself, the operation time of personnel adjustment process, improves operation efficiency, and makes the adjustment process more intuitive, reducing the need for repeated adjustments due to unsuitable adjustments.
