Abstract
Description
Technical Field
[0001] The utility model belongs to the field of machine-made sand production, and more specifically, particularly relates to an environmentally friendly dry-type dust-free machine-made sand production device. Background Art
[0002] After the existing machine-made sand is initially processed through mining, it is placed in the sand making machine for initial crushing of the sand and gravel. The side of the crusher is connected with a dust collection port. The crusher will generate a large amount of dust in the process of crushing sand and gravel. In order to prevent the dust from being output together with the sand and gravel, the dust collection system on the side of the sand making machine will collect the dust inside by suction during the crushing process. The dust will run to the side, and the sand and gravel that are heavier than the dust will be output downwards.
[0003] Based on the above, the author of the utility model found that the existing dry dust-free machine-made sand production equipment has the following main shortcomings, such as:
[0004] In order to prevent sand and gravel from entering, the dust collection port has a small entrance space that is only used for the input of dust. However, when the dust passes through the collection port, part of it will stick to the collection port. When the equipment is running continuously, the resistance of the collection port will become greater and greater, resulting in reduced dust collection effect of the equipment, thus affecting subsequent treatment.
[0005] Therefore, it is necessary to propose an environmentally friendly dry dust-free machine-made sand production equipment. Utility Model Content
[0006] In order to solve the problem that part of the dust will stick to the collection port when passing through the collection port, the resistance of the collection port will become greater and greater during the continuous operation of the equipment, resulting in reduced dust collection effect of the equipment, thus affecting subsequent processing.
[0007] The purpose and effect of the environmentally friendly dry dust-free machine-made sand production equipment of the utility model are achieved by the following specific technical means:
[0008] Its structure includes a sand making machine, a feeding port, a dust removal pipe, a motor, a fixed frame, a feeding port, and a base. The upper end of the sand making machine is welded with a feeding port and the dust removal pipe is connected to the inside of the sand making machine. The fixed frame is welded to the outer surface of the sand making machine. The motor is connected to the inside of the sand making machine. The feeding port is connected to the lower end of the sand making machine. The base is fixed to the fixed frame. The dust removal pipe is connected between the sand making machine and the dust collector.
[0009] The dust removal pipe includes a large interception net, a through pipe, a small interception net, a protective shell, a crushing chamber, a crushing shaft, a motor connecting shaft, and an inner cavity. The large interception net is connected to the small interception net through the through pipe, and the large interception net is spaced between the through pipe and the inner cavity. The crushing chamber is fixed to the inner surface of the protective shell and is evenly distributed in a circular shape. The crushing shaft is located at the center of the crushing chamber distribution. The motor connecting shaft is connected to the crushing shaft. The large interception net is in a vertical state, and its small interception net is in an inclined state. The functions of the two are the same. The large interception net and the small interception net move horizontally according to the suction force inside the through pipe, and the motor connecting shaft drives the crushing shaft and the crushing chamber to rotate through the power of the motor.
[0010] As a further improvement of the present invention, the large interception net includes a through opening, a limit block, a return spring, and an interception grid. The return spring is abutted between the limit block and the interception grid. The interception grid is located in the through opening space. The return springs are a group of two and are located at the upper and lower ends of the sides of the interception grid. The limit block is in the shape of a rectangular parallelepiped. The return spring supports the interception grid. When the interception grid is subjected to external suction, the return spring will be squeezed. The limit block limits the maximum movement range of the interception grid.
[0011] As a further improvement of the present invention, the intercepting grid includes a limiting track, a movable body, an inner grid, and an outer grid. The outer grid is fixed between two limiting tracks. The movable body is connected to the inner grid and moves within the limiting track. The inner grid can move horizontally along the direction of the outer grid. The inner grid and the outer grid are concave and convex and complement each other. The inner grid and the outer grid are an arc-shaped structure as a whole.
[0012] As a further improvement of the present utility model, the outer frame includes an elastic layer, a buffer layer, and a fixed block. The fixed blocks are evenly distributed in a fan shape. The buffer layer is attached to the surface of one end of the fixed block. The elastic layer is installed on the side of the fixed block away from the buffer layer. The buffer layer is an arc-shaped structure. The elastic layer is made of rubber, which has a buffering effect on external force and protects the main body. The fixed block fixes the overall general shape, and the buffer layer has a buffering and resistance effect on external force.
[0013] As a further improvement of the utility model, the limiting path includes a limiting groove, a sliding aid layer, a sliding ball, and a dustproof layer. The sliding aid layer is attached to the inner surface of the limiting groove, and the sliding ball rests on the surface of the sliding aid layer to assist sliding. The dustproof layer is fixed to the surface of the limiting groove, and the inner side of the dustproof layer rests on the outer surface of the sliding ball and is installed symmetrically up and down. The sliding aid layer is a smooth surface that allows the sliding ball to move more smoothly. The dustproof layer blocks the gap between the sliding ball and the limiting groove to prevent dust from running in and affecting movement.
[0014] As a further improvement of the utility model, the dustproof layer includes a middle solid block, an epitaxial layer, a stretching layer, and a soft body. The stretching layer is adhered between two soft bodies, the epitaxial layer is wrapped around the outer surface of the middle solid block, the soft body is adhered to the outer surface of the epitaxial layer, and the stretching layer has a fan-shaped structure and can expand and contract according to the resistance of external force.
[0015] As a further improvement of the utility model, an interception grid is provided between the inner cavity and the space of the through opening, the interception grid is located inside the protective shell for horizontal movement, and the interception grid is divided into two complementary left and right halves.
[0016] Compared with the prior art, the utility model has the following beneficial effects:
[0017] 1. The suction of the dust removal equipment sucks the large and small interception nets through the through pipe, and the interception grid will move along the limit path. When some dust accumulates on the surface of the outer grid, the grid space will gradually accumulate and become smaller. When the suction force is also reduced, the return spring will lose resistance and push the inner grid toward the outer grid. The protruding parts of each grid will be stuck in the concave grid part, so that the accumulated dust will be pushed away. The suction force will operate as usual, and the inner and outer grids will be separated again, so that the dust generated by the initial crushing of the sand and gravel can be smoothly adsorbed. When the sand and gravel are initially crushed, more dust is generated, which can be handled by the dust removal equipment, and the screens separated between the spaces can also be handled as soon as possible when there is accumulation.
[0018] 2. When the inner grid moves along the sliding layer and the limit groove through the sliding ball, its soft body can deform and fit along with the contacted part, and its stretching layer can assist the pulling and deformation of the soft body, so that the soft body can still smoothly contact the surface of the sliding ball, so that the dust will not run into the moving space of the sliding ball. It can isolate the moving parts during the continuous adsorption of dust. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0028] The utility model is further described below in conjunction with the accompanying drawings:

[0032] The dust removal pipe 3 includes a large interception net 31, a through pipe 32, a small interception net 33, a protective shell 34, a crushing chamber 35, a crushing shaft 36, a motor connecting shaft 37, and an inner cavity 38.

The crushing chamber 35 is fixed to the inner surface of the protective shell 34 and is evenly distributed in a circular shape. The crushing shaft 36 is located at the center of the distribution of the crushing chamber 35. The motor connecting shaft 37 is connected to the crushing shaft 36. The large interception net 31 is in a vertical state, and its small interception net 33 is in an inclined state. The functions of the two are the same. The large interception net 31 and the small interception net 33 move horizontally according to the suction force inside the through pipe 32. The motor connecting shaft 37 drives the crushing shaft 36 and the crushing chamber 35 to rotate through the power of the motor. The large interception net 31 is an arc shape that matches the shape of the protective shell 34.
[0033] Among them, the large interception net 31 includes a through opening 001, a limit block 002, a return spring 003, and an interception grid 004. The return spring 003 is against the limit block 002 and the interception grid 004. The interception grid 004 is located in the space of the through opening 001. The return springs 003 are grouped in two and are located at the upper and lower ends of the sides of the interception grid 004. The limit block 002 is a rectangular parallelepiped shape. The return spring 003 supports the interception grid 004. When the interception grid 004 is subjected to external suction, the return spring 003 will be squeezed. The limit block 002 limits the maximum moving range of the interception grid 004. When the return spring 003 loses external force at the connecting part, it will push it back.
[0034] Among them, the intercepting grid 004 includes a limiting track a1, a moving body a2, an inner grid a3, and an outer grid a4. The outer grid a4 is fixed between the two limiting tracks a1. The moving body a2 is connected to the inner grid a3 and moves in the limiting track a1. The inner grid a3 can move horizontally along the direction of the outer grid a4. The inner grid a3 and the outer grid a4 are concave and convex and complement each other. The inner grid a3 and the outer grid a4 are an arc-shaped structure as a whole. When the inner grid a3 and the outer grid a4 are combined, they are in a complete arc state.
[0035] Among them, the outer grid a4 includes an elastic layer w11, a buffer layer w12, and a fixed block w13. The fixed block w13 is evenly distributed in a fan shape. The buffer layer w12 is attached to the surface of one end of the fixed block w13. The elastic layer w11 is installed on the side of the fixed block w13 away from the buffer layer w12.

The dust-proof layer g04 is fixed to the surface of the limiting groove g01, and the inner side of the dust-proof layer g04 rests on the outer surface of the sliding ball g03 and is installed symmetrically up and down. The slip-assisting layer g02 is a smooth surface that allows the sliding ball g03 to move more smoothly. The dust-proof layer g04 blocks the gap between the sliding ball g03 and the limiting groove g01 to prevent dust from running in and affecting the movement. The sliding ball g03 is a spherical structure and can move better. The limiting groove g01 fixes the moving range of the connecting part.
[0037] The specific usage and function of this embodiment are as follows:
[0038] In the utility model, unprocessed sand and gravel are placed into the sand making machine 1 through the feed port 2, and the equipment is started by the operator. The motor 4 will drive the crushing shaft 36 and the crushing chamber 35 to run together to crush the sand and gravel through the motor connecting shaft 37, and the dust removal equipment connected to the dust removal pipe 3 is also started together. The dust removal equipment is connected to the sand making machine 1 through the dust removal pipe 3, and the internal through pipe 32 and the inner cavity 38 are the same space. The suction force of the dust removal equipment sucks the large interception net 31 and the small interception net 33 through the through pipe 32, and the interception grid 004 will move along the limit path a1, and the return spring 003 will be squeezed, the outer grid a4 and the inner grid a3 will be separated, and the dust will be sucked through the grid between the outer grid a4 and the inner grid a3 When some dust accumulates on the surface of the outer grid a4, the grid space will gradually become smaller and smaller. When the suction force is also reduced, the return spring 003 will lose resistance and push the inner grid a3 toward the outer grid a4. The protruding parts of each of them will be stuck in the concave grid part, so that the accumulated dust will be pushed away. When the inner grid a3 and the outer grid a4 collide with each other, the buffer layer w12 will protect them. The sand and gravel are located inside the inner cavity 38 for processing and the impact on the outer grid a4 is protected by the elastic layer w11. When the accumulated part is pushed away, the suction force operates as usual, and the inner grid a3 and the outer grid a4 are separated again, so that the dust generated by the initial crushing of the sand and gravel can be smoothly adsorbed.
[0039] Embodiment 2:
[0040] As attached Figure 7 To Attachment Figure 8 As shown:

The stretching layer s3 is adhered between two soft bodies s4, the epitaxial layer s2 is wrapped on the outer surface of the middle solid block s1, and the soft body s4 is adhered to the outer surface of the epitaxial layer s2. The stretching layer s3 has a fan-shaped structure and can expand and contract according to the resistance of external force. The soft body s4 is a rubber soft body with a certain elasticity and can better adhere to the resisting part.
[0042] There is an interception grid 004 between the inner cavity 38 and the space of the through opening 001. The interception grid 004 is located inside the protective shell 34 and moves horizontally. The interception grid 004 is divided into two complementary left and right halves. The through pipe 32 is an irregular U-shaped pipe.
[0043] The specific usage and function of this embodiment are as follows:
[0044] In the utility model, during the operation of the sand and stone crushing and dust removal equipment, the inner grid a3 and the outer grid a4 are separated and moved, and the adsorbed dust will pass through the two. When the inner grid a3 moves along the sliding layer g02 and the limiting groove g01 through the sliding ball g03, the dust-proof layer g04 will contact the surface of the sliding ball g03, and the soft sticker s4 can deform and fit along with the contacted part, and the stretching layer s3 can assist the pulling deformation of the soft sticker s4. The epitaxial layer s2 at the upper end plays a pulling and buffering role. The middle solid block s1 fixes the overall approximate shape, so that the soft sticker s4 can still smoothly contact the surface of the sliding ball g03, so that the dust will not run into the moving space of the sliding ball g03.
