Description

Technical Field

[0001] The utility model relates to the field of material conveying, and particularly relates to a device for reducing the material accumulation angle of a belt conveyor. Background Technique

[0002] When the belt conveyor conveys materials, since it is very difficult to evenly spread the materials on the belt conveyor when the materials are transferred to the belt conveyor, and some unexpected situations are encountered during the transportation process. Therefore, the material accumulation conditions at different positions on the belt conveyor will be different.

[0003] Some positions may have only a thin layer of materials, while the materials accumulated at some positions may be very high, forming a relatively large material accumulation angle. If the material accumulation angle on the belt conveyor is large, it is easy to cause material throwing and spilling on site, and will cause dust, increasing the workload of the post and polluting the environment.

[0004] Therefore, it is necessary to set up corresponding material blocking devices on the belt conveyor to reduce the material docking angle. However, if a general material blocking device is fixedly arranged, it is easy to have a violent collision with a large material pile with a large accumulation angle that moves quickly, which will lead to material throwing and spilling on site and cause dust. And setting up a movable material blocking device can automatically bounce up when colliding with the fast-moving materials, avoiding violent collisions, and thus avoiding material throwing and spilling. However, when the material blocking device falls, it will heavily hit the materials, which is also easy to cause dust. Content of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide a device for reducing the material accumulation angle of a belt conveyor to solve the technical problem in the prior art that it is easy to have a violent collision with materials when reducing the material docking angle on the belt conveyor, resulting in material throwing and spilling and dust.

[0006] Based on the above purpose, the utility model provides a device for reducing the material accumulation angle of a belt conveyor, including a belt conveyor for conveying materials, and side baffles are arranged on both sides of the belt conveyor. The device further includes:

Each group of material blocking rollers has several, and the material blocking rollers in the same group are arranged at equal intervals in the left-right transverse direction of the belt conveyor and are independent of each other.

[0010] Further, the connecting component includes a fixing rod, a connecting ring and a connecting plate.

[0024] Specific implementation manners and principles

[0025] In order to make the purpose, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with specific embodiments.

[0026] It should be noted that unless otherwise defined, the technical terms or scientific terms used in the present utility model should have the ordinary meanings understood by those with ordinary skills in the field to which the present utility model belongs.

The terms such as "upper", "lower", "left", "right" are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0027] In the first aspect of the present utility model, as Figure 1 and Figure 2As shown, since the material accumulation conditions at different positions on the belt conveyor 101 may vary, a material retaining roller 106 is provided on the upper end surface of the belt conveyor 101 to block the material with a large accumulation angle, thereby flattening the material on the belt conveyor 101. To improve the effect of blocking the material with a large accumulation angle and flattening the material on the belt conveyor 101, multiple groups of material retaining rollers 106 are provided. Different groups of material retaining rollers 106 are arranged at equal intervals in the front-back direction of the belt conveyor 101. Each group of material retaining rollers 106 has several, and the material retaining rollers 106 in the same group are arranged at equal intervals in the left-right transverse direction of the belt conveyor 101 and are independent of each other.

[0028] Moreover, since the material retaining rollers 106 in different groups are staggered, it can effectively block the material with a large accumulation angle, thereby flattening the material on the belt conveyor 101.

[0029] The specific setting of the material retaining roller 106 is as Figure 1 and Figure 3 shown. The material retaining roller 106 is rotatably connected to the side baffle 102 through a connecting component. The connecting component includes a fixed rod 103, a connecting ring 104, and a connecting plate 105. The fixed rod 103 is located above the belt conveyor 101 and is fixedly connected between the two side baffles 102. The material retaining roller 106 is rotatably connected to the lower end of a connecting plate 105. The upper end of this connecting plate 105 is fixedly connected to a connecting ring 104, and this connecting ring 104 is rotatably connected to the fixed rod 103. All the material retaining rollers 106 in the same group are respectively rotatably connected to the same fixed rod 103 through a connecting plate 105 and a connecting ring 104.

[0030] Therefore, when the material retaining roller 106 collides with the fast-moving material with a large accumulation angle, it will be forced and automatically bounce up. When the material retaining roller 106 automatically bounces up, it drives the connecting plate 105 and the connecting ring 104 to rotate around the fixed rod 103 as the center. As a result, after the material with a large accumulation angle is blocked and dispersed to a certain extent, it will pass through the gap between the enlarged material retaining roller 106 and the upper end surface of the belt conveyor 101, avoiding strong collisions, and thus avoiding material throwing, spilling, and dust raising.

[0031] Since multiple groups of material retaining rollers 106 are provided and different groups of material retaining rollers 106 are arranged at equal intervals in the front-back direction of the belt conveyor 101, the material with a large accumulation angle will eventually be completely dispersed and flattened after being blocked by multiple groups of material retaining rollers 106, effectively blocking the material with a large accumulation angle, thereby flattening the material and avoiding the situation of material throwing, spilling, and dust raising at the site.

[0032] On the other hand, as Figure 3 、 Figure 4 and Figure 5 shown, a damping mechanism connected to the connecting plate 105 is provided on each connecting plate 105.

[0033] Specifically, the damping mechanism includes a roller 108, a telescopic rod 109, a square tube 110 and a fixed plate 111, wherein the roller 108 is rotatably connected to the lower end of the telescopic rod 109, and the roller 108 is rollingly connected to the roller groove 107 on the connecting plate 105, the upper end of the telescopic rod 109 is movably connected in the square tube 110, the upper end of the square tube 110 is fixedly connected to the lower end of the fixed plate 111, and the fixed plate 111 is fixedly connected between the two side baffles 102. The fixed plate 111 is also fixedly connected to a cylinder 112, the inner cavity of the cylinder 112 is connected to the inner cavity of the corresponding square tube 110, and the upper end of the cylinder 112 is provided with a vent 115, and the outer side of the vent 115 is provided with a cover plate 113, the cover plate 113 is slidably connected to the cylinder 112 through a sliding rod, and the cover plate 113 is also provided with microholes 114.

[0034] Therefore, when the stopper roller 106 automatically springs up, it takes the connecting plate 105 and the connecting ring 104 to rotate upwards with the fixed rod 103 as the center of a circle. Then the connecting plate 105 will lift up the roller 108 and the telescopic rod 109, and the telescopic rod 109 will extend into the square tube 110.

[0035] During this process, the roller 108 can roll in the roller groove 107 on the connecting plate 105 to avoid interference. It should be noted that the roller 108 cannot be separated from the roller groove 107.

[0036] When the telescopic rod 109 is quickly extended into the square tube 110, the air pressure in the inner cavity of the square tube 110 will increase rapidly, and the inner cavity of the cylinder 112 is connected to the inner cavity of the corresponding square tube 110, so the air pressure in the inner cavity of the cylinder 112 will also increase rapidly. Although the cover plate 113 blocking the upper vent 115 of the cylinder 112 is provided with micropores 114, the aperture is small, so it may not be exhausted in time. Therefore, the cover plate 113 is set to be slidably connected to the cylinder 112 through a sliding rod, so the larger air pressure will lift the cover plate 113, so that the vent 115 is completely exposed, and then the air is smoothly discharged, reducing the air pressure in the inner cavity of the cylinder 112 and the corresponding square tube 110. Therefore, the blocking roller 106 can be smoothly and quickly bounced up.

[0037] However, when the material baffle roller 106 descends, the damping mechanism can play a damping role. Because when the material baffle roller 106 descends, it drives the connecting plate 105 and the connecting ring 104 to rotate downward with the fixed rod 103 as the center. Then the connecting plate 105 drives the roller 108 and the telescopic rod 109 to descend, and the telescopic rod 109 extends out of the square cylinder 110. This causes the air pressure in the inner cavities of the square cylinder 110 and the cylindrical cylinder 112 to rapidly decrease. At this time, since the cover plate 113 also drops to cover the air vent 115, the inner cavities of the square cylinder 110 and the cylindrical cylinder 112 can only intake air through the micropores 114 on the cover plate 113. Due to the small aperture, the air intake rate is low, so the telescopic rod 109 cannot quickly extend out of the square cylinder 110. Thus, it plays a damping role. It slows down the descending speed of the material baffle roller 106, avoiding the material baffle roller 106 hitting the material heavily, and thus avoiding the occurrence of material throwing and spilling. Detailed implementation mode

[0038] When the belt conveyor 101 is transporting materials, if materials with a large stacking angle pass through the material baffle roller 106, the material baffle roller 106 will block the materials with a large stacking angle and make them spread out. When the material baffle roller 106 collides with the fast-moving materials with a large stacking angle, it will be forced and bounce up automatically. When the material baffle roller 106 bounces up automatically, it drives the connecting plate 105 and the connecting ring 104 to rotate with the fixed rod 103 as the center. As a result, after the materials with a large stacking angle are blocked and spread out to a certain extent, they will pass through the gap between the enlarged material baffle roller 106 and the upper end face of the belt conveyor 101, avoiding strong collisions, and thus avoiding the occurrence of material throwing and spilling.

[0039] However, although the material baffle roller 106 bounces up under force and fails to completely flatten and block the materials to make them spread out, multiple groups of material baffle rollers 106 are provided, and different groups of material baffle rollers 106 are arranged at equal intervals in the front-back direction of the belt conveyor 101. Therefore, the materials with a large stacking angle will finally spread out and flatten completely after being blocked by multiple groups of material baffle rollers 106, effectively blocking the materials with a large stacking angle, and then flattening the materials, avoiding the occurrence of material throwing and spilling on site and causing dust.

[0040] When the material baffle roller 106 bounces up automatically, it drives the connecting plate 105 and the connecting ring 104 to rotate upward with the fixed rod 103 as the center. Then the connecting plate 105 will push up the roller 108 and the telescopic rod 109, and the telescopic rod 109 will extend into the square cylinder 110. This causes the air pressure in the inner cavities of the square cylinder 110 and the cylindrical cylinder 112 to also rapidly increase, so it will push up the cover plate 113, making the air vent 115 completely exposed, and then discharging air smoothly, ensuring that the material baffle roller 106 can bounce up smoothly and quickly.

[0041] When the material blocking roller 106 descends, the connecting plate 105 drives the roller 108 and the telescopic rod 109 to descend, and the telescopic rod 109 extends out of the square cylinder 110. This causes the air pressure in the inner cavities of the square cylinder 110 and the cylindrical barrel 112 to rapidly decrease. At this time, since the cover plate 113 also drops to cover the air vent 115, the inner cavities of the square cylinder 110 and the cylindrical barrel 112 can only intake air through the micro-holes 114 on the cover plate 113. Due to the small aperture, the air intake rate is low, so the telescopic rod 109 cannot quickly extend out of the square cylinder 110. This further plays a damping role, slowing down the descending speed of the material blocking roller 106, preventing the material blocking roller 106 from hitting the material heavily, and thus avoiding dust generation.

[0042] Based on the above, the present utility model sets multiple groups of material blocking rollers 106 in the moving direction of the belt conveyor 101, and different groups of material blocking rollers 106 are arranged staggeredly, which can effectively block materials with a large stacking angle, and then flatten the materials on the belt conveyor 101. At the same time, the material blocking roller 106 is set to be movable and can automatically bounce up when colliding with fast-moving materials, avoiding violent collisions, and thus avoiding material throwing, spilling, and dust generation. A damping mechanism is also provided. When the movable material blocking roller 106 bounces up and then descends, it will be hindered by the damping mechanism, making the descending speed of the material blocking roller 106 slow down, and thus avoiding the material blocking roller 106 from hitting the material heavily, and further avoiding material throwing, spilling, and dust generation.
