Description

Technical Field

[0001] The present application relates to the technical field of belt conveyor unloading, and in particular to a device for preventing material accumulation in a unloading hopper and adjusting a material unloading point. Background Art

[0002] Material yard conveyors are widely used in various industrial fields, especially in situations requiring continuous, large-scale material transportation, such as mines, power plants, and building materials factories. In material yards, conveyor belts can effectively transport materials from one location to another, improving production efficiency and reducing labor intensity. Currently, due to the different properties of the materials in the various hoppers of material yard conveyor belts, material accumulation easily occurs on the inner wall of the hopper. Viscous materials accumulate more quickly, and if not promptly handled, they can clog the material outlet, affecting normal production. Different materials with different properties will produce different segregations when landing on the inner wall of the material outlet, which will cause the lower belt to deviate due to different material drop points, causing friction between the belt and the bracket, causing damage to the belt, so this needs to be improved. Utility Model Content

[0003] In order to effectively solve the problem of difficult cleaning of accumulated materials, prevent damage to the belt caused by incorrect material drop points, improve production efficiency, and ensure the safety of material cleaning personnel, this application provides a device for preventing material accumulation in the lower hopper and adjusting the material drop point.

[0004] The present application provides a device for preventing material accumulation in a hopper and adjusting the material drop point, which adopts the following technical solutions:

[0005] A device for preventing material accumulation in a lower hopper and adjusting the material dropping point comprises an upper belt and a lower belt, wherein the length direction of the upper belt is perpendicular to the length direction of the lower belt, and the lower belt is located below the output end of the upper belt. Two brackets are vertically arranged on one side of the lower belt, and the two brackets are arranged along the length direction of the lower belt. A triangular prism is arranged between the two brackets, and a side wall of one side of the triangular prism is inclined toward the direction of the lower belt.

[0006] By adopting the above technical solution, a triangular prism is set up, and the surface of the triangular prism is used as the impact point for material discharge. The inclined setting of the side wall of the triangular prism can enable the material to accurately fall along the surface of the triangular prism onto the surface of the belt below, so as to ensure that the belt below will not deviate and wear due to the incorrect discharge point, thereby extending the service life of the entire device.

[0007] Optionally, a central axis is provided in the triangular prism, and the triangular prism is rotatably connected to the bracket via the central axis.

[0008] By adopting the above technical solution, a central axis is set to drive the triangular prism to rotate, thereby adjusting the inclination angle of the side wall of the triangular prism. Therefore, the material drop point can be flexibly adjusted according to different working conditions. It has high practicality and flexibility. When there is too much material on one surface, the triangular prism can be rotated and other surfaces can be used to take over. The staff can then clean up the surface with excessive material accumulation.

[0009] Optionally, a fixed brake for fixing the triangular prism is installed between the bracket and the central axis.

[0010] By adopting the above technical solution, a fixed brake is set to fix the central axis after the central axis drives the triangular prism to rotate, thereby fixing the adjusted angle and making the material drop point more accurate and stable.

[0011] Optionally, bearings are provided at both ends of the central shaft.

[0012] By adopting the above technical solution, setting up bearings can effectively reduce the resistance of the central shaft when it rotates relative to the bracket, reduce wear, and improve the smoothness of the rotation of the central shaft and triangular prism, thereby extending the service life of the device of the present application.

[0013] Optionally, each side wall of the triangular prism is provided with a wear-resistant lining.

[0014] By adopting the above technical solution, the wear-resistant lining can effectively reduce material accumulation and ensure the normal and efficient transportation of materials. At the same time, it is also convenient for rapid replacement after wear, saving replacement costs and having higher economic benefits.

[0015] Optionally, a head wheel sealing cover is provided at the output end of the upper belt, and the head wheel sealing cover is located above the lower belt.

[0016] By adopting the above technical solution, setting up a head wheel sealing cover can prevent the material from splashing when leaving the output end of the upper belt, thereby ensuring that the material can accurately fall on the surface of the triangular prism and then be transported in the direction of the lower belt, thereby improving the accuracy and safety of material transportation.

[0017] Optionally, a side wall of the head wheel sealing cover away from the upper belt is provided with a clearance opening for the triangular prism to rotate through.

[0018] By adopting the above-mentioned technical solution and opening a clearance hole, the triangular prism will not collide with the head wheel sealing cover when the staff adjusts the angle of the triangular prism. On the one hand, the convenience of adjusting the triangular prism is improved, and on the other hand, the structure of the triangular prism and the head wheel sealing cover can be protected, thereby extending the service life of the device of the present application.

[0019] Optionally, the lower side of the triangular prism side wall is arranged lower than the surface of the upper belt.

[0020] By adopting the above technical solution, it can be fully ensured that the material falling from the upper belt can fall along the side wall of the triangular prism onto the surface of the lower belt, thereby improving the accuracy and efficiency of feeding.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. Set up a triangular prism, and use the surface of the triangular prism as the material drop impact point. The inclined setting of the triangular prism side wall can make the material fall accurately along the surface of the triangular prism onto the surface of the belt below, so as to ensure that the belt below will not deviate and wear due to the misalignment of the drop point, thereby extending the service life of the entire device;

[0023] 2. The central axis is set to drive the triangular prism to rotate, and then adjust the inclination angle of the triangular prism side wall. Therefore, the material drop point can be flexibly adjusted according to different working conditions. It has high practicality and flexibility. When there is too much material on one surface, the triangular prism can be rotated and other surfaces can be used to take over. The staff can then clean up the surface with too much material accumulation;

[0024] 3. Setting a fixed brake can fix the center axis after the center axis drives the triangular prism to rotate, thereby fixing the adjusted angle and making the material landing point more accurate and stable;

[0025] 4. The head wheel sealing cover can prevent the material from splashing when leaving the output end of the upper belt, thereby ensuring that the material can accurately fall on the surface of the triangular prism and then be transported in the direction of the lower belt, thereby improving the accuracy and safety of material transportation.
