[0002] Coal mines generally use belt conveyors to transport them. The head of the belt conveyor is generally equipped with a material guide trough, which guides the coal through the material guide trough, so that the coal falls accurately onto the belt conveyor and is transported.

[0003] However, during the use of the guide trough, it was found that when coal fell into the guide trough from the feed port, it would impact the conveyor belt in the guide trough. When large pieces of coal fell, it might even cause longitudinal tearing of the conveyor belt. When the coal fell, it would bring external airflow, which would enter the interior of the guide trough, increasing the wind speed inside it, and then stirring up coal dust to form dust, causing dust leakage pollution. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a material guide chute with a falling material buffer and dust suction function, which solves the technical problems in the existing technology that the impact force when large pieces of coal fall causes the conveyor belt to tear and the rolled-up airflow causes dust leakage and pollution, thereby achieving the purpose of protecting the conveyor belt and treating the dust.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a material guide trough with material falling buffering and dust suction function, including a conveyor belt installed inside the material guide trough body, a crushing and dust removal mechanism for crushing large pieces of material is provided in the material guide trough body, and a buffering protection mechanism for buffering the impact force of falling materials is provided under the conveyor belt.

[0006] The crushing and dust removal mechanism includes a feed port installed on the top of the material guide trough body, and two rotating shafts are rotatably connected in the material guide trough body and symmetrically installed with the center line of the feed port as the axis, and flip plates are equidistantly installed in a ring shape on the rotating shaft, and the flip plates are provided with material leakage notches, and crushing nails are evenly installed on the outside of the flip plates. The material guide trough body is also provided with a dust removal component for sucking the airflow generated when the material falls and the dust generated when the material is crushed.

[0007] Preferably, the dust removal assembly includes a vacuum cleaner installed on the top of the material guide trough body, and the dust suction port of the vacuum cleaner is installed with a connecting pipe, a diversion pipe is symmetrically installed at the bottom of the connecting pipe, a dust suction pipe with a front end extending into the interior of the material guide trough body is installed on the diversion pipe, and a dust hood is installed at the front end of the dust suction pipe.

[0008] Preferably, the buffer protection mechanism includes a support plate installed at the bottom of the conveyor belt, a base is symmetrically installed on the front and rear sides of the guide trough body, a buffer spring is installed between the base and the support plate, a limiting sleeve located inside the buffer spring is installed on the base, and a guide slide rod connected to the top of the support plate is connected to the limiting sleeve for sliding up and down. A secondary buffer component is also provided between the support plate and the guide trough body for secondary buffering of the impact force of the falling material.

[0009] Preferably, the secondary buffer assembly includes a connecting rod installed between two bases, the front and rear sides of the connecting rod are slidably connected with sliders, the connecting rod is provided with a compression spring whose front and rear ends are respectively connected to the two sliders, a movable seat is installed on the slider and the bottom of the support plate, and a connecting arm is movably connected between the two groups of movable seats.

[0013] 1. The utility model slows down the falling speed of the material by causing the material to hit the flip plate, thereby reducing the impact force of the falling material. When the material hits the flip plate, the crushing nails installed on the outside of the flip plate use the impact force of the falling material to crush the large pieces of material, thereby preventing the falling of large pieces of material from tearing the conveyor belt.

[0014] 2. The conveyor belt of the utility model is subjected to impact force to hit the support plate, causing it to compress the buffer spring, and the elasticity of the buffer spring itself is used to absorb and release the impact force. The setting of the limiting sliding sleeve and the guide sliding rod prevents the buffer spring from bending under force and affecting the effect of buffer protection.

[0015] 3. In the present invention, when the impact force of falling materials hits the support plate, the support plate moves downward, causing the movable seat at its bottom to move downward, thereby driving the internal connecting arm to rotate in the movable seat, and pushing the two sliders to slide relative to each other along the connecting rod and squeeze the compression spring, thereby utilizing the elasticity of the compression spring itself to perform secondary absorption and slow release of the impact force.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] Based on the existing problems in the prior art where the impact of falling large pieces of coal causes the conveyor belt to tear and the airflow to cause dust leakage and pollution, this embodiment provides a guide chute with a falling material buffering and dust collection function. Please refer to Figures 1-6The embodiment provides a material guide chute with a material falling buffering and dust collection function, which can protect the conveyor belt and process dust. The buffering material guide chute with material crushing and dust collection function includes a conveyor belt 2 installed inside the material guide chute body 1, and a crushing dust removal mechanism 3 for crushing large pieces of material is provided inside the material guide chute body 1. A buffering protection mechanism 4 for buffering the impact force of falling materials is provided below the conveyor belt 2. The crushing dust removal mechanism 3 is used to crush large pieces of material to prevent the conveyor belt 2 from being damaged by the impact force of its falling. The airflow generated when the material falls and the dust generated when the material is crushed are also sucked away. The setting of the buffering protection mechanism 4 buffers the impact force of the material falling through multiple buffers, thereby better protecting the conveyor belt 2.

[0028] Since the impact of large pieces of coal falling in the prior art causes the conveyor belt to tear and the rolled-up airflow to cause dust leakage pollution, the equipment is provided with a crushing and dust removal mechanism 3, which includes a feed port 301 installed on the top of the guide trough body 1, and two rotating shafts 302 are rotatably connected in the guide trough body 1 and symmetrically installed with the center line of the feed port 301 as the axis, and a turning plate 303 is equidistantly installed on the rotating shaft 302 in an annular shape, and a material leakage notch is opened on the turning plate 303, and crushing nails 304 are evenly installed on the outer side of the turning plate 303. The guide trough body 1 is also provided with a device for controlling the airflow generated when the material falls and the material crushing. When the material falls onto the conveyor belt 2 in the guide trough body 1 through the feed port 301, small pieces of material directly fall through the gap between the two flip plates 303, and relatively large materials hit the flip plates 303 and drive the rotating shaft 302 to rotate. At this time, the falling speed of the material is slowed down by the interception of the flip plates 303, thereby reducing the impact force of the falling material. When the large pieces of material hit the flip plates 303, the crushing nails 304 installed on the outside of the flip plates 303 use the impact force of the falling materials to crush the large pieces of material, thereby preventing the large pieces of material from falling and tearing the conveyor belt 2.

[0029] Since a certain amount of dust is generated when the material is crushed, and the airflow raised by the falling material itself causes the dust to leak out, the equipment is also provided with a dust removal component 305, which includes a dust collector 3051 installed on the top of the material guide trough body 1, and the dust suction port of the dust collector 3051 is installed with a connecting pipe 3052, and a diversion pipe 3053 is symmetrically installed at the bottom of the connecting pipe 3052, and a dust suction pipe 3054 is installed on the diversion pipe 3053, the front end of which extends into the interior of the material guide trough body 1, and a dust suction hood 3055 is installed at the front end of the dust suction pipe 3054. When the dust collector 3051 is started to generate suction, the dust generated during the crushing and the airflow raised by the falling material are sucked into the diversion pipe 3053 through the cooperation of the dust suction pipe 3054 and the dust suction hood 3055, and then sucked into the dust collector 3051 through the connecting pipe 3052, thereby preventing dust leakage from causing environmental pollution.

[0030] Even if the impact force of the falling material is initially intercepted by the flip plate 303, the mass of the material itself will also bring a certain impact force. Therefore, the device is also provided with a buffer protection mechanism 4, which includes a support plate 401 installed at the bottom of the conveyor belt 2, and bases 402 are symmetrically installed on the front and back sides of the guide trough body 1. A buffer spring 403 is installed between the base 402 and the support plate 401, and a limiting sleeve 404 is installed on the base 402, which is located inside the buffer spring 403, and the limiting sleeve 404 slides up and down in a continuous manner. There is a guide slide 405 connected to the top of the support plate 401, and a secondary buffer component 406 is provided between the support plate 401 and the guide trough body 1 to perform secondary buffering on the impact force of the falling material. When the material falls onto the conveyor belt 2, the conveyor belt 2 is subjected to the impact force to hit the support plate 401, causing it to compress the buffer spring 403, and the elasticity of the buffer spring 403 itself is used to absorb and release the impact force. The setting of the limiting sliding sleeve 404 and the guide slide 405 prevents the buffer spring 403 from bending under force, which affects the effect of buffer protection.

[0031] The guide trough body 1 is provided with rollers 501 for supporting the conveyor belt 2. Side rollers 502 are symmetrically installed on both sides of the conveyor belt 2. The conveyor belt 2 is supported by the rollers 501 and the side rollers 502 to enable normal operation.

[0032] Support legs 601 are installed on both sides of the guide chute body 1, and a dust curtain 602 is installed at the discharge port of the guide chute body 1. The provision of the dust curtain 602 can better prevent dust from leaking out.

[0033] Example 2

[0034] On the basis of Example 1, Figures 1-6As shown, in order to further protect the conveyor belt 2 and reduce the damage to the conveyor belt 2 caused by the impact of falling materials, the device is also provided with a secondary buffer component 406, which includes a connecting rod 4061 installed between the two bases 402, and a slider 4062 is slidably connected to the front and rear sides of the connecting rod 4061. A compression spring 4063 is sleeved on the connecting rod 4061, and the front and rear ends are respectively connected to the two sliders 4062. A movable seat 406 is installed on the slider 4062 and the bottom of the support plate 401. 4. A connecting arm 4065 is movably connected between the two sets of movable seats 4064. When the impact force of the falling material hits the support plate 401, the support plate 401 moves downward to move the movable seat 4064 at its bottom downward, thereby driving the connecting arm 4065 inside it to rotate in the movable seat 4064, and push the two sliders 4062 to slide relative to each other along the connecting rod 4061 and squeeze the compression spring 4063, so as to utilize the elasticity of the compression spring 4063 itself to perform secondary absorption and slow release of the impact force, thereby better protecting the conveyor belt 2.
