Abstract
Description
A type of vibrating coal chute Technical Field
[0001] This utility model relates to the field of coal chute technology, specifically to a vibrating coal chute with an inner lining. Background Technology
[0002] Coal chutes (also known as coal drop pipes for belt conveyors) are key components used for coal transportation in underground or surface transportation systems in coal mines. In traditional coal chutes, because the bottom plate is fixed, coal is prone to adhesion due to friction, humidity, or electrostatic adsorption as it moves within the chute. Over time, this can cause blockages, thus affecting the efficiency of coal transportation. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a vibrating coal chute with an inner lining that avoids or reduces coal adhesion to the bottom plate through vibration.
[0004] The technical solution of this utility model is implemented as follows:
[0005] A vibrating coal chute with an inner lining includes a coal chute hopper and a coal chute channel installed at the bottom of the coal chute hopper, wherein the coal chute channel is inclined as a whole.
[0006] Multiple inner vibrating plates arranged in a linear array along the length of the coal chute are installed on the inner bottom surface of the coal chute, and the inner vibrating plates completely cover the bottom of the coal chute.
[0007] The top of each inner lining vibrating plate is rotatably mounted on the bottom plate of the coal chute via a connecting shaft, and the bottom of each inner lining vibrating plate is equipped with a spring that can vibrate up and down around the connecting shaft.
[0008] Using the above scheme, when the coal is transported along the coal chute, each inner lining vibrating plate will vibrate up and down, which can effectively avoid or reduce the blockage caused by coal adhesion, thereby improving the coal transportation efficiency.
[0009] In a preferred embodiment of a lined vibrating coal chute, two guide rods are vertically fixed on the lower surface of the bottom plate of the lining vibrating plate. The guide rods pass through the clearance groove located at the bottom, and springs are fitted onto the guide rods.
[0010] The spring includes spring one and spring two, which are located on the inner and outer sides of the base plate, respectively.
[0011] The clearance chute is a strip-shaped chute, which is opened along the length of the coal chute.
[0012] Using the above scheme, in order to achieve the up-and-down vibration of the inner lining vibrating plate, when the coal just falls onto the inner lining vibrating plate, spring one is compressed. Once the coal leaves the inner lining vibrating plate, the elastic action of spring one will drive the inner lining vibrating plate to vibrate up and down, thereby shaking off all the coal on the upper surface of the inner lining vibrating plate.
[0013] In a preferred embodiment of a lined vibrating coal chute, the inner side of the bottom plate is also fixed with multiple vibration protrusions located at the bottom of the lining vibrating plate; wherein the upper surface of the vibration protrusion is an arc surface.
[0014] By adopting the above scheme, in order to improve the vibration of the inner lining vibrating plate, the inner lining vibrating plate will hit the vibrating protrusion when it vibrates up and down, thereby transmitting the vibration to the inner lining vibrating plate and thus improving the shaking effect on the coal.
[0015] In a preferred embodiment of a lined vibrating coal chute, the two guide rods are also concentrically connected to a vibration handle, which is located on the outside of the bottom plate.
[0016] Using the above method, in order to facilitate the manual periodic cleaning of coal adhering to the inner lining vibrating plate, the vibrating handle is manually pulled to make the inner lining vibrating plate vibrate up and down, thereby achieving the effect of cleaning the coal adhering to the inner lining vibrating plate.
[0017] In a preferred embodiment of a lined vibrating coal chute, the inner wall of the coal chute and the upper surface of the lining vibrating plate are coated with a composite polymer wear-resistant material layer, and the surface of the composite polymer wear-resistant material layer is provided with micron-level textured surface.
[0018] To improve the service life of the inner wall and lining vibrating plate of the coal chute, the above solution is adopted. The vibrating plate is covered with a composite polymer wear-resistant material layer to improve its wear resistance, and micron-level textured surface is provided to reduce the contact area between the two.
[0019] After adopting the above technical solution, the beneficial effects of this utility model are:
[0020] 1. When the coal is transported along the coal chute, the vibrating plates of the inner lining vibrating chute vibrate up and down, which can effectively avoid or reduce the blockage caused by coal adhesion, thereby improving the coal conveying efficiency.
[0021] 2. In order to achieve the up-and-down vibration of the inner lining vibrating plate, when the coal just falls onto the inner lining vibrating plate, the first spring is compressed. Once the coal leaves the inner lining vibrating plate, the elastic action of the first spring will drive the inner lining vibrating plate to vibrate up and down, thereby shaking off all the coal on the upper surface of the inner lining vibrating plate.
[0022] 3. In order to improve the vibration of the inner lining vibrating plate, the inner lining vibrating plate will hit the vibrating protrusion when it vibrates up and down, thereby transmitting the vibration to the inner lining vibrating plate and improving the shaking effect on the coal.
[0023] 4. To facilitate the manual and periodic cleaning of coal adhering to the inner lining vibrating plate, the vibrating handle is manually pulled to make the inner lining vibrating plate vibrate up and down, thereby achieving the effect of cleaning the coal adhering to the inner lining vibrating plate.
[0024] 5. In order to improve the service life of the inner wall and lining vibrating plate of the coal chute, a composite polymer wear-resistant material layer is covered to improve its wear resistance, and a micron-level texture is set to reduce the contact area between the two.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Referring to Figures 1 to 6, a vibrating coal chute includes a coal chute hopper 1 and a coal chute channel 2 installed at the bottom of the coal chute hopper 1. The coal chute channel 2 is inclined as a whole. Multiple vibrating plates 3 arranged linearly along the length of the channel are installed on the inner bottom surface of the coal chute channel 2, completely covering the bottom plate 4 of the channel. The top of each vibrating plate 3 is rotatably mounted on the bottom plate 4 of the channel via a connecting shaft 5, and the bottom of each vibrating plate 3 is equipped with a spring that vibrates up and down around the connecting shaft 5. During coal conveying, the coal along the coal chute channel 2 causes each vibrating plate 3 to vibrate up and down, effectively preventing or reducing coal blockage due to adhesion, thereby improving coal conveying efficiency.
[0036] Referring to Figures 4 and 6, two guide rods 6 are vertically fixed to the lower surface of the bottom plate 4 of the inner lining vibrating plate 3. The guide rods 6 pass through the clearance groove 7 located at the bottom, and springs are fitted onto the guide rods 6. The springs include spring 8 and spring 9, which are located on the inner and outer sides of the bottom plate 4, respectively. The clearance groove 7 is a strip-shaped groove that is opened along the length of the coal chute 2. In order to achieve the up-and-down vibration of the inner lining vibrating plate 3, when the coal just falls onto the inner lining vibrating plate 3, spring 8 is compressed. Once the coal leaves the inner lining vibrating plate 3, the elastic action of spring 8 will drive the inner lining vibrating plate 3 to vibrate up and down, thereby shaking off all the coal on the upper surface of the inner lining vibrating plate 3.
[0037] Referring to Figure 4, the inner side of the base plate 4 is also fixed with multiple vibration protrusions 10 located at the bottom of the inner lining vibrating plate 3; wherein, the upper surface of the vibration protrusion 10 is an arc surface. In order to improve the vibration of the inner lining vibrating plate 3, the inner lining vibrating plate 3 will strike the vibration protrusions 10 when vibrating up and down, thereby transmitting the vibration to the inner lining vibrating plate 3, thereby improving the shaking effect on the coal.
[0038] Referring to Figure 7, the two guide rods 6 are also concentrically connected to a vibration handle 11, which is located on the outside of the base plate 4. In order to facilitate manual periodic cleaning of coal adhering to the inner lining vibrating plate 3, the vibration handle 11 is manually pulled to make the inner lining vibrating plate 3 vibrate up and down, thereby achieving the effect of cleaning the coal adhering to the inner lining vibrating plate 3.
[0039] Furthermore, the inner wall of the coal chute 2 and the upper surface of the inner lining vibrating plate 3 are coated with a composite polymer wear-resistant material layer (such as polyurethane or modified rubber), and the surface of this composite polymer wear-resistant material layer has micron-level uneven texture. In order to improve the service life of the inner wall of the coal chute 2 and the inner lining vibrating plate 3, they are covered with a composite polymer wear-resistant material layer to improve their wear resistance, and micron-level uneven texture is set to reduce the contact area between the two.
[0040] The working principle of this utility model:
[0041] In application, coal is fed into the coal chute 1 and then conveyed to the conveyor belt along the coal chute channel 2. As the coal falls onto the inner vibrating plate 3, the spring 8 is compressed. Once the coal leaves the inner vibrating plate 3, the elasticity of the spring 8 causes the inner vibrating plate 3 to vibrate up and down, thus shaking off all the coal adhering to its surface. Later, to facilitate manual cleaning of the coal adhering to the inner vibrating plate 3 periodically, the vibration handle 11 is manually pulled, causing the inner vibrating plate 3 to vibrate up and down, achieving the effect of cleaning the coal adhering to the inner vibrating plate 3. This inner vibrating coal chute effectively avoids or reduces blockage caused by coal adhesion, thereby improving coal conveying efficiency.
[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
