Description

Technical Field

[0001] This utility model relates to the field of coal washing technology, specifically to a coal washing plant unloading guide structure. Background Technology

[0002] The plow-type unloader in a coal washing plant is a material diversion unloading device installed on a belt conveyor. Its core function is to use plow blades to cut into the material flow, causing materials such as coal to slide off the side of the conveyor belt to a designated unloading port or area. A power source pushes a push rod to extend, which, through a guide mechanism, causes the plow blades to fall, while simultaneously, the idler rollers rise to flatten the conveyor belt. The lower edge of the plow blades fits tightly against the conveyor belt, cutting into the material and causing it to slide off to the unloading port.

[0003] In most existing unloading structures, all materials are unloaded at once. This unloading method can easily lead to greater pressure on the plow blades. When there is a lot of material, the material will move upwards, which will also cause greater stress on the plow blades. This not only makes the plow blades more prone to damage, but also reduces the service life of the structure. Meanwhile, some existing structures, when in use, may result in poor unloading effect due to one-time unloading. The conveyor belt may deform due to the weight of the material, causing some small materials to fail to be discharged in time, thus reducing the unloading effect of the structure and reducing its applicability.

[0014] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0015] Please see Figure 1-4As shown, a material unloading guide structure for a coal washing plant includes a frame 1. A power mechanism 2 is installed inside the frame 1. A fixed shell 3 is provided on the surface of the power mechanism 2. With the cooperation of the power mechanism 2, the fixed shell 3 can rotate, facilitating its use. A first guide frame 4 is fixedly connected to one side of the fixed shell 3. Both sides of the surface of the first guide frame 4 are designed with an inclined structure. Under the action of the first guide frame 4, it can be placed on the surface of the conveyor belt through the cooperation of the power mechanism 2 and the fixed shell 3, thereby enabling the first guide frame 4 to unload material from the surface of the conveyor belt, facilitating material handling. A threaded rod 5 is provided inside the first guide frame 4, and a second guide frame 6 is threadedly connected to the surface of the threaded rod 5. The first guide frame 4 and the second guide frame 6 are used in conjunction, and... With the same tilt angle, the second guide frame 6 can first contact and guide a larger amount of material, thereby unloading part of the material. Then, with the cooperation of the first guide frame 4, the remaining material is unloaded. This batch unloading of material from the conveyor belt surface reduces the pressure on the first guide frame 4 and the threaded rod 5 during use, effectively extending their service life and reducing the likelihood of damage. Furthermore, batch unloading reduces the stress on the structure, effectively improving the stability and accuracy of the threaded rod 5 during use. The position of the second guide frame 6 can be adjusted through the cooperation of the threaded rod 5, thereby adjusting the batch unloading amount and improving the applicability of the structure.

[0016] A bearing seat 11 is fixedly connected to the bottom of the threaded rod 5. The bottom of the bearing seat 11 is fixedly connected to the inner wall of the first guide frame 4. Under this action, the bearing seat 11 can limit one end of the threaded rod 5, so that the threaded rod 5 can be relatively stable when rotating and not in use, avoiding easy positional deviation that would affect the adjustment of the position of the second guide frame 6. A support mechanism 7 is installed on the surface of the first guide frame 4. The support mechanism 7 can support the second guide frame 6, making it more stable during use and preventing deformation due to excessive force caused by lack of support. This effectively improves the service life of the second guide frame 6.

[0017] A blower 8 is bolted to the top of the fixed housing 3. A cleaning housing 10 is installed at the air outlet of the blower 8. The other end of the cleaning housing 10 penetrates into the interior of the fixed housing 3 and is fixedly connected to the inner wall of the penetration point. Under this action, after the blower 8 accelerates the air, the air enters the interior of the fixed housing 3 through the cleaning housing 10, thereby cleaning small debris on the surface of the conveyor belt, effectively improving the unloading effect of the structure and ensuring the cleanliness of the conveyor belt. An air curtain mechanism 9 is installed on one side of the surface of the cleaning housing 10, which can blow air onto the surface of the second guide frame 6. This creates an air curtain on the surface of the second guide frame 6, thereby reducing friction between the material and the second guide frame 6 and effectively extending its service life. A pusher frame 12 is fixedly connected to the surface of the first guide frame 4. The surface of the pusher frame 12 has an arc-shaped structure design. Under this effect, when the first guide frame 4 comes into contact with the material, the pusher frame 12 guides the material through its shape, thereby reducing the possibility of the material directly colliding with the first guide frame 4 and effectively extending its service life.

[0018] The support mechanism 7 includes a connecting frame 71 fixed to one side of the first guide frame 4. The surface of the connecting frame 71 is provided with a mounting groove 72. A ball bearing 73 is rotatably connected to the inner cavity of the mounting groove 72. The surface of the ball bearing 73 is slidably connected to the inner wall of the second guide frame 6. Under this action, the second guide frame 6 can be supported by the cooperation of the ball bearing 73, so that the second guide frame 6 will not easily deform. It can also guide the second guide frame 6 when it moves, so that the second guide frame 6 is more stable when it moves, and effectively improves the applicability of the second guide frame 6.

[0019] The air curtain mechanism 9 includes a flexible hose 91 connected to the surface of the cleaning housing 10. Both ends of the flexible hose 91 are connected to connectors 92. The surface of the connectors 92 is connected to nozzles 93. There are several nozzles 93. The surface of the nozzles 93 is embedded in the interior of the second guide frame 6. Under this action, air can be discharged from the nozzles 93 through the cooperation of the flexible hose 91 and the connectors 92, so that the air can form an air curtain on the surface of the second guide frame 6, thereby reducing the friction between the material and the second guide frame 6, effectively improving the unloading speed, and also improving the service life of the second guide frame 6.

[0020] It is worth noting that the technical features such as the frame 1 and the power mechanism 2 proposed in this technical solution should be regarded as prior art. The specific structure, working principle and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0021] Working principle: First, the power mechanism 2 moves the fixed shell 3 and all its surface parts, then places the structure on the surface of the conveyor belt. The power mechanism 2 then brings the first guide frame 4 into contact with the conveyor belt surface. Next, the threaded rod 5 rotates, moving the second guide frame 6 to adjust the distance between the bottom of the first guide frame 4 and the bottom of the second guide frame 6, facilitating batch unloading. The movement of the belt pulley, in conjunction with the second guide frame 6 and the first guide frame 4, achieves batch unloading, effectively extending the structure's service life. During unloading, the blower 8 is activated, and in conjunction with the cleaning shell 10, cleans the surface of the conveyor belt after unloading, further improving the unloading effect. Furthermore, the hose 91 and connector 92 work together to allow the nozzle 93 to exhaust air onto the surface of the second guide frame 6, reducing friction between the material and the second guide frame 6 through the air curtain effect, effectively improving the structure's applicability.
