Description

Technical Field

[0001] This invention relates to the field of belt conveyor unloading technology, and particularly to an adjustable guide plate for the unloading port of a belt conveyor. Background Technology

[0002] Belt conveyors are mainly composed of a channel steel frame, a cloth-reinforced rubber belt, rollers, a discharge chute, a scraper cleaner, idlers, and a motor reducer. They are the most widely used raw material transportation equipment in the glass manufacturing industry, mainly responsible for the transfer of powdery or granular production raw materials. The stability and reliability of their operation are directly related to the continuous production efficiency of the glass production line.

[0003] In the actual operation of existing belt conveyor systems, when materials are discharged from the head of the conveyor, there is a common problem: the falling angle is fixed and cannot be adjusted according to the working conditions. Coupled with the large weight of the powder itself and the high speed of the raw material transport, it is difficult to accurately control the direction of material scattering. This not only leads to uneven material accumulation but also generates significant impact force. Continuous impact force directly acts on the chute walls in the discharge area or on one side of the belt in the next area below, causing a series of problems such as dust spillage, dust pollution, wear and tear on the chute walls leading to material leakage, and belt misalignment. These issues severely affect the service life and operational stability of the equipment. Furthermore, these defects are extremely difficult to rectify after installation, and traditional fixed guide vanes cannot adapt to changes in material conveying volume, resulting in poor equipment operational flexibility and high maintenance costs.

The adjustable guide plate structure comprises a guide plate base, an inner UPE liner, and connecting ear plates. The inner UPE liner is fixedly installed at the front end of the guide plate base. Four connecting ear plates are symmetrically fixedly installed at the rear end of the guide plate base. Four U-shaped fixing brackets are symmetrically fixedly installed at the rear end of the discharge hopper. A screw adjustment component is rotatably mounted on the connecting ear plates via a pin. The component consists of a connecting column, an adjusting screw, a fixing nut, and an adjusting nut. The adjusting screw is fixedly installed at the rear end of the connecting column. The fixing nut and the adjusting nut are both installed on the adjusting screw. The adjusting screw passes through the rear wall of the hopper and the U-shaped fixing frame. An upper connecting shield is fixedly installed on the upper rear end of the guide plate base plate and the upper side of the rear inner wall of the hopper. The upper connecting shield consists of an upper fixing plate, a lower fixing plate, and a rubber flexible plate. The upper fixing plate and the lower fixing plate are respectively fixedly installed at the upper and lower ends of the rubber flexible plate.

[0006] Preferably, four first straight slots are symmetrically opened on the rear side wall of the hopper.

[0007] Preferably, the openings of the four U-shaped fixing frames all face the hopper, and the U-shaped fixing frames are fixedly connected to the hopper by welding. Each of the four U-shaped fixing frames has a second straight groove on its rear side wall, and the second straight groove is coaxial with the first straight groove.

[0008] Preferably, the guide plate base plate and the inner UPE liner plate on the adjustable guide plate structure are fixedly connected by screws, and the guide plate base plate and the connecting ear plate are fixedly connected by welding. The connecting ear plate is provided with a first shaft hole.

[0009] Preferably, the front end of the connecting column on the lead screw adjusting component is provided with an ear plate groove, and two second shaft holes are symmetrically provided on the connecting column. The second shaft holes are connected to the ear plate groove. The connecting column is located in the hopper and is movably sleeved on the connecting ear plate through the ear plate groove. The second shaft hole is coaxial with the first shaft hole.

[0010] Preferably, the connecting post on the lead screw adjusting component is fixedly connected to the adjusting lead screw by welding, and the adjusting lead screw passes through the first straight slot and the second straight slot in sequence.

[0011] Preferably, the fixing nut on the lead screw adjusting component is close to the rear end of the hopper, and there are two adjusting nuts, which are respectively close to the front end and the rear end of the rear side wall of the U-shaped fixing frame.

[0012] Preferably, the pin is rotatably mounted in the first shaft hole and two second shaft holes.

[0013] Preferably, the upper fixing plate on the upper connecting shield is fixedly installed on the upper side of the inner wall of the rear side of the hopper by screws, and the height of the upper fixing plate is higher than that of the adjustable guide plate structure. The lower fixing plate is fixedly installed on the upper side of the rear end of the guide plate base plate by screws.

[0014] Compared with the prior art, the present invention has the following beneficial effects: (1) By setting an adjustable guide plate structure consisting of a guide plate base plate, an inner UPE plate and a connecting ear plate in the hopper, and setting four U-shaped fixing frames at the rear end of the hopper, and setting four screw adjustment components consisting of connecting columns, adjusting screws, fixing nuts and adjusting nuts on the adjustable guide plate structure and the four U-shaped fixing frames, the tilt angle and front and rear position of the adjustable guide plate structure can be flexibly adjusted, the falling direction and scattering trajectory of the material can be accurately controlled, and the material can be adapted to the transfer needs of materials with different conveying volumes and different particle sizes. This effectively alleviates the unilateral impact of the material on the hopper wall and the belt below, avoids uneven material accumulation and belt deviation, reduces the wear rate of the hopper wall, extends the service life of the equipment, reduces on-site dust pollution, improves the working environment of the operators, and eliminates the need for large-scale modification of the hopper in the later stage. The guiding conditions can be quickly adjusted by simply turning the adjusting nuts and fixing nuts and moving the screw adjustment components, which greatly improves the operational flexibility of the equipment and reduces the maintenance cost in the later stage.

[0015] (2) By setting an upper connecting shielding component consisting of an upper fixed plate, a lower fixed plate and a rubber soft plate on the hopper and adjustable guide plate structure, the upper connecting shielding component can block the upper gap between the adjustable guide plate structure and the rear side wall of the hopper, preventing the material from passing through the gap, ensuring that the adjustable guide plate structure has a good guiding effect, and preventing the material from getting stuck in the gap, causing the adjustment mechanism to jam or the equipment parts to be damaged, thus ensuring the continuous and stable operation of the belt conveyor feeding system; at the same time, the rubber soft plate has good flexibility and deformation ability, and can adapt to the angle and position adjustment of the adjustable guide plate structure, always maintaining the sealing state of the gap, without affecting the normal adjustment function of the adjustable guide plate structure.

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, an adjustable guide plate for the discharge port of a belt conveyor includes an adjustable guide plate structure 1. The adjustable guide plate structure 1 is located inside the discharge hopper 3 and close to the rear side wall of the discharge hopper 3. The adjustable guide plate structure 1 consists of a guide plate base plate 8, an inner UPE liner plate 9, and connecting ear plates 10. The inner UPE liner plate 9 is fixedly installed at the front end of the guide plate base plate 8. There are four connecting ear plates 10, which are symmetrically fixedly installed at the rear end of the guide plate base plate 8. Four U-shaped fixing brackets 4 are symmetrically fixedly installed at the rear end of the discharge hopper 3. A screw adjusting component 2 is rotatably installed on the connecting ear plate 10 through a pin shaft 18. The screw adjusting component 2 is connected by a connecting column 1. 2. The device consists of an adjusting screw 15, a fixing nut 16, and an adjusting nut 17. The adjusting screw 15 is fixedly installed at the rear end of the connecting column 12. The fixing nut 16 and the adjusting nut 17 are both installed on the adjusting screw 15. The adjusting screw 15 passes through the rear side wall of the hopper 3 and the U-shaped fixing frame 4. An upper connecting shield 5 is fixedly installed on the upper rear side of the guide plate base plate 8 and the upper side of the rear inner wall of the hopper 3. The upper connecting shield 5 consists of an upper fixing plate 19, a lower fixing plate 20, and a rubber flexible plate 21. The upper fixing plate 19 and the lower fixing plate 20 are respectively fixedly installed at the upper and lower ends of the rubber flexible plate 21.

[0020] Furthermore, four first straight slots 6 are symmetrically opened on the rear side wall of the hopper 3. The openings of the four U-shaped fixing brackets 4 all face the hopper 3. The U-shaped fixing brackets 4 are fixedly connected to the hopper 3 by welding. A second straight slot 7 is opened on the rear side wall of each of the four U-shaped fixing brackets 4. The second straight slot 7 is coaxial with the first straight slot 6. The guide plate base plate 8 on the adjustable guide plate structure 1 is fixedly connected to the inner UPE liner plate 9 by screws. The guide plate base plate 8 is fixedly connected to the connecting ear plate 10 by welding. A first shaft hole 11 is opened on the connecting ear plate 10. The lead screw adjusting component 2 is... The connecting column 12 has an ear plate groove 13 at its front end. Two second shaft holes 14 are symmetrically formed on the connecting column 12, communicating with the ear plate groove 13. The connecting column 12 is located inside the hopper 3 and is movably fitted onto the connecting ear plate 10 via the ear plate groove 13. The second shaft hole 14 is coaxial with the first shaft hole 11. The connecting column 12 on the screw adjusting component 2 is fixedly connected to the adjusting screw 15 by welding. The adjusting screw 15 passes sequentially through the first straight groove 6 and the second straight groove 7. The fixing nut 16 on the screw adjusting component 2 is tightly attached to the rear end of the hopper 3, and the adjusting nut 17... Two pins 18 are respectively attached to the front and rear ends of the rear side wall of the U-shaped fixing frame 4, and are rotatably installed in the first shaft hole 11 and the two second shaft holes 14. An adjustable guide plate structure 1 consisting of a guide plate base plate 8, an inner UPE plate 9 and a connecting ear plate 10 is set in the hopper 3. Four U-shaped fixing frames 4 are set at the rear end of the hopper 3. Four screw adjusting parts 2 consisting of a connecting column 12, an adjusting screw 15, a fixing nut 16 and an adjusting nut 17 are set on the adjustable guide plate structure 1 and the four U-shaped fixing frames 4. The tilt angle and front and rear of the adjustable guide plate structure 1 can be flexibly adjusted. Positioning allows for precise control of the material's falling direction and scattering trajectory, adapting to the transfer needs of materials with different conveying capacities and particle sizes. It effectively mitigates the unilateral impact of materials on the walls of the discharge hopper 3 and the belt below, preventing uneven material accumulation and belt misalignment. Simultaneously, it reduces the wear rate of the hopper walls, extends the equipment's service life, reduces on-site dust pollution, and improves the working environment for operators. No large-scale modifications to the discharge hopper 3 are required in the future; the flow conditions can be quickly adjusted simply by turning the adjusting nut 17, fixing nut 16, and moving the screw adjusting component 2, significantly improving the equipment's operational flexibility and reducing subsequent maintenance costs.

[0021] Furthermore, the upper fixing plate 19 on the upper connecting shield 5 is fixedly installed on the upper side of the rear inner wall of the hopper 3 by screws, and the height of the upper fixing plate 19 is higher than that of the adjustable guide plate structure 1. The lower fixing plate 20 is fixedly installed on the upper side of the rear end of the guide plate base plate 8 by screws. By providing the upper connecting shield 5, which consists of the upper fixing plate 19, the lower fixing plate 20, and the rubber flexible plate 21, on the hopper 3 and the adjustable guide plate structure 1, the upper connecting shield 5 can restrict the connection between the adjustable guide plate structure 1 and the rear wall of the hopper 3. The upper gap between the two is sealed to prevent materials from passing through the gap, ensuring that the adjustable guide plate structure 1 has a good guiding effect. At the same time, it prevents materials from getting stuck in the gap, causing the adjustment mechanism to jam or equipment parts to be damaged, and ensures the continuous and stable operation of the belt conveyor feeding system. Meanwhile, the rubber soft plate 21 has good flexibility and deformation ability, and can adapt to the angle and position adjustment of the adjustable guide plate structure 1, always maintaining the sealing state of the gap, without affecting the normal adjustment function of the adjustable guide plate structure 1.

[0022] It should be noted that when adjusting the front and rear positions of the adjustable guide plate structure 1 within the hopper 3, first loosen the fixing nuts 16 on the four lead screw adjusting components 2 using a tool, so that the fixing nuts 16 are completely disengaged and away from the rear wall of the hopper 3. Then, loosen the adjusting nuts 17 on each lead screw adjusting component 2, so that the two adjusting nuts 17 on each lead screw adjusting component 2 are disengaged from the front and rear ends of the rear wall of the U-shaped fixing frame 4, leaving sufficient adjustment margin. At this time, the adjusting screws 15 on each lead screw adjusting component 2 can move freely in the front and rear direction within the first straight groove 6 and the second straight groove 7. Then, move the four lead screw adjusting components 2 back and forth in the same direction to ensure... Ensure that the moving distance of the four lead screw adjustment parts 2 is completely consistent. Through the connecting ear plate 10 and the pin shaft 18, drive the entire adjustable guide plate structure 1 to move smoothly back and forth in the hopper 3, so as to avoid the adjustable guide plate structure 1 from tilting left and right until the adjustable guide plate structure 1 reaches the preset front and back position. After the adjustment is completed, first tighten the adjusting nut 17 on each lead screw adjustment part 2 in sequence, so that the two adjusting nuts 17 on each lead screw adjustment part 2 are tightly attached to the front end and the rear end of the rear side wall of the U-shaped fixing frame 4 respectively, lock the adjusting lead screw 15 to the U-shaped fixing frame 4, and then tighten the fixing nut 16 to make it tightly attached to the rear side wall of the hopper 3, thus completing the final locking of the front and back position adjustment.When adjusting the inclination angle of the adjustable guide plate structure 1 within the hopper 3, first use a tool to loosen the fixing nuts 16 on the two lower lead screw adjusting parts 2, so that the fixing nuts 16 are completely disengaged and away from the rear wall of the hopper 3. Then, loosen the adjusting nuts 17 on the two lower lead screw adjusting parts 2 respectively, so that the two adjusting nuts 17 on each lead screw adjusting part 2 are disengaged from the front and rear ends of the rear wall of the U-shaped fixing frame 4, leaving sufficient adjustment margin. At this time, the adjusting screws 15 on the two lower lead screw adjusting parts 2 can be adjusted in the first straight groove. The upper two lead screw adjusting parts 2 remain in their original locked positions, while the lower two lead screw adjusting parts 2 move back and forth in the same direction to ensure that their movement distances are completely consistent. At this time, the lower two lead screw adjusting parts 2 will drive the adjustable guide plate structure 1 to rotate smoothly with the upper two pins 18 as the rotation axis through the lower two connecting ear plates 10 and the two pins 18. At the same time, the adjustable guide plate structure 1 will also rotate smoothly with the lower two pins 18. 18. Relative rotation occurs, thereby precisely changing the tilt angle of the adjustable guide plate structure 1. During the adjustment process, the tilt state of the adjustable guide plate structure 1 needs to be observed in real time to avoid left or right deviation, until the adjustable guide plate structure 1 reaches the preset guiding angle. After adjustment, first tighten the adjusting nuts 17 on the two lower screw adjusting parts 2 in sequence, so that the two adjusting nuts 17 on each lower screw adjusting part 2 are tightly against the front and rear ends of the rear wall of the U-shaped fixing frame 4, thereby locking and fixing the adjusting screw 15 to the U-shaped fixing frame 4. Tighten the fixing nut 16 on the lower screw adjusting component 2 to make it fit tightly against the rear wall of the hopper 3, completing the final locking of the entire angle adjustment process; finally, check whether the rubber flexible plate 21 of the upper connecting shield 5 has undergone normal adaptive deformation with the adjustment of the adjustable guide plate structure 1, without tearing, jamming or sealing failure, and at the same time confirm that the contact gap between the left and right ends of the adjustable guide plate structure 1 and the upper connecting shield 5 and the left and right side walls of the hopper 3 is uniform, without excessive gap or jamming, to ensure the guiding effect and the stability of equipment operation.

[0023] During operation, when the belt conveyor discharges material, it is thrown into the hopper 3 from the tail end of the upstream belt conveyor at a certain speed and angle. It first impacts the surface of the UPE liner 9 at the front end of the adjustable guide plate structure 1. The UPE liner 9, with its excellent wear resistance and self-lubricating properties, can effectively withstand the continuous impact load of the material while significantly reducing the frictional resistance between the material and the plate surface, preventing powder or granular materials from adhering to the plate surface and causing discharge blockage. Under the combined action of its own gravity and initial impact inertia, the material slides smoothly downwards along the pre-adjusted inclined plate surface of the adjustable guide plate structure 1. The adjustable guide plate structure 1, through precise adjustment of its front-to-back position and inclination angle, forcibly changes the falling direction and throwing trajectory of the material, allowing it to fall evenly, smoothly, and centrally into the center area of ​​the downstream belt, effectively avoiding unilateral impact on the downstream belt and unilateral accumulation of material on the belt. This system addresses various issues while significantly reducing the direct impact of materials on the hopper 3 wall, lowering the wear rate of the hopper wall, extending the service life of the hopper 3, reducing dust spillage caused by high-speed material impact, and improving the on-site working environment. During this process, the upper fixing plate 19 of the upper connecting shield 5 is fixed to the upper side of the rear inner wall of the hopper 3, and the lower fixing plate 20 is fixed to the upper side of the rear end of the guide plate base plate 8. The rubber soft plate 21 can adaptively bend and deform according to the position and angle changes of the adjustable guide plate structure 1, always tightly sealing the upper gap between the adjustable guide plate structure 1 and the rear wall of the hopper 3, preventing materials from passing through the gap and bypassing the adjustable guide plate structure 1, ensuring the stable and reliable guiding effect of the adjustable guide plate structure 1, and preventing materials from getting stuck in the gap, causing the screw adjustment component 2 to jam or other equipment parts to be damaged, ensuring that the entire belt conveyor feeding system can operate continuously and stably.

[0024] In addition, the left and right ends of the adjustable guide plate structure 1 and the upper connecting shield 5 must be in close contact with the left and right side walls of the hopper 3 to ensure that the material does not overflow from the gaps on both sides and to ensure the guiding and sealing effect. The rubber soft plate 21 must have good flexibility, wear resistance and anti-aging properties when it is selected, and its length must be long enough to completely cover the upper gap between the adjustable guide plate structure 1 and the rear side wall of the hopper 3. When the adjustable guide plate structure 1 is adjusted in front and back position and tilt angle, it must always maintain sufficient deformation margin and will not be tight, torn or fail to seal due to stretching or bending, so as to continuously and stably seal the gap.

[0025] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
