Raw material crushing device for environment-friendly building material production

Abstract

This utility model relates to the field of raw material crushing technology and discloses a raw material crushing device for the production of environmentally friendly building materials. It achieves screen hole cleaning by setting up a drive roller, teeth, screen frame, screen holes, and brush blocks. Gear A drives the screen frame to rotate circumferentially between the drive roller, driven roller, and auxiliary roller through the meshing of the teeth and screen holes. When the screen frame rotates, it drives the crushed material to pass through the screen evenly. Qualified material falls downwards through the screen holes, while unqualified material rotates synchronously with the screen frame after being propelled by a deflector plate. When the screen frame drives the material to the teeth, the teeth, due to their deep penetration into the screen holes, can push out the material blocked or stuck inside the screen holes. Subsequently, the screen frame continues to rotate, driving the material to the brush blocks. The bristles at the end of the brush blocks brush the material into the crusher body for secondary crushing. The sticky material pushed out by the teeth at the screen hole openings is also brushed away by the bristles at the end of the brush blocks, thus achieving the effect of cleaning the screen holes.

Description

Technical Field

[0001] This utility model relates to the field of raw material crushing technology, and in particular to a raw material crushing device for the production of environmentally friendly building materials. Background Technology

[0002] Common raw materials for environmentally friendly building materials include renewable or natural materials, industrial / construction waste recycling, and low environmental impact materials. Among them, industrial / construction waste recycling includes recycled aggregates, slag, fly ash, waste glass, etc. Construction waste, ores, slag, and other materials need to be crushed before they can be used, and crushing equipment is usually used for production and processing.

[0003] In existing technologies, there are certain shortcomings in the crushing of recycled aggregates, slags, and other materials. For example, after crushing and screening, materials with qualified and unqualified particle sizes will flow out when they are piled up separately. However, unqualified particles cannot be directly returned to the crusher for further crushing. In addition, concrete waste and slag may contain certain sticky substances, such as mud or clay. When sieving, mud and clay may stick to the screen holes, causing the screen hole diameter to become smaller, which prevents the aggregates and slags that are subsequently screened from passing through the screen holes smoothly for screening. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a raw material crushing device for the production of environmentally friendly building materials, which has the advantages of avoiding clogging and reducing dust, thus solving the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a raw material crushing device for the production of environmentally friendly building materials, comprising a housing, a crusher body fixedly installed inside the housing, a reducer connected to one side of the crusher body, a motor connected to one side of the reducer, the output shaft of the motor being driven by the reducer and the crusher body, a screen frame rotatably installed inside the housing, a drive roller and a driven roller respectively installed on the outer sides of the screen frame inside the housing, auxiliary rollers installed on the inner sides of the screen frame inside the housing, and a transmission device installed between one side of the crusher body and the drive roller.

[0006] Through the above structural design, the screen holes are cleaned by the cooperation between the screen frame, teeth, and brush blocks. The dust overflow during crushing is reduced by the cooperation between the screen frame baffle and the box body. When the crusher crushes the material, a certain amount of dust will be generated. The rotation of the inner surface of the screen frame and the baffle can effectively prevent a large amount of dust from overflowing to the outside during crushing.

[0007] Preferably, the outer ring of the drive roller is uniformly toothed in a circular shape, and rotating blocks are rotatably installed on both sides of the drive roller, driven roller and auxiliary roller on the outer and inner arc edges of the screen frame, and a gear A is provided at the end of the drive roller on one side of the housing.

[0008] With the above structural configuration, when the gear A is driven to rotate, the drive roller rotates synchronously. Since the teeth mesh with the screen holes, the teeth can synchronously drive the screen frame to rotate circumferentially between the drive roller, the driven roller, and the auxiliary roller during the rotation process.

[0009] Preferably, the crusher body includes a housing, a drive gear A, and a drive gear B. A set of cutters is symmetrically and rotatably installed inside the crusher body. Housings are provided on both sides of the crusher body. A drive gear A and a drive gear B are rotatably installed on one side of one housing. The drive gear A and the drive gear B are respectively connected to the cutter set inside the crusher body. The drive gear A and the drive gear B are meshed with each other. The drive gear A is connected to the output shaft of the reducer.

[0010] With the above structural configuration, the output shaft of the motor drives the drive gear A to rotate synchronously through the reducer. The drive gear A meshes with the drive gear B, thereby causing the blade assembly inside the crusher body to rotate in opposite directions, thus achieving the crushing of materials.

[0011] Preferably, the surface of the screen frame is uniformly provided with screen holes in a circular shape. The cross-section of the screen holes is trapezoidal. The long side of the screen holes is longer than the long side of the teeth. The short side of the screen holes is adapted to the short side of the teeth. The screen holes and teeth mesh with each other.

[0012] With the above structural design, since the long side of the screen hole is larger than the long side of the tooth, it will not obstruct the meshing transmission between the tooth and the screen hole, and can drive the screen frame to rotate smoothly between the drive roller, the driven roller and the auxiliary roller.

[0013] Preferably, the inner surface of the screen frame is uniformly provided with a ring-shaped baffle, the baffle is inclined, the screen frame is symmetrically fixedly installed with baffles inside the box, the inner ring of the screen frame is in contact with the outer wall of the baffle, a brush block is fixedly installed between the baffles, the end of the brush block is provided with bristles, and the bristles are in contact with the inner surface of the screen frame.

[0014] With the above structural setup, the crushed material falls vertically onto the inner surface of the screen frame between the deflector plates. As the screen frame rotates, the qualified particle size material falls through the screen holes and downwards, while the unqualified particle size is deflected by the deflector plates and follows the screen frame to rotate. When it moves to the brush block, the brush block brushes the material off and it falls vertically downwards into the interior of the crusher body for secondary crushing.

[0015] Preferably, the transmission device includes gear B and gear C, both of which are rotatably mounted on one side of the housing. Gear B meshes with drive gear B, gear B meshes with gear C, and gear C meshes with gear A.

[0016] With the above structural configuration, the transmission device achieves multi-stage transmission through the meshing of gears B and C with drive gears B and A.

[0017] This utility model has the following advantages:

[0018] 1. This environmentally friendly building material production raw material crushing device achieves screen hole cleaning by setting up a drive roller, teeth, screen frame, screen holes, brush blocks, etc. Gear A drives the screen frame to rotate circumferentially between the drive roller, driven roller, and auxiliary roller through the meshing of the teeth and screen holes. When the screen frame rotates, it drives the crushed material to pass through the screen evenly. Qualified material falls down through the screen holes, while unqualified material rotates synchronously with the screen frame by being propelled by the pusher plate. When the screen frame drives the material to the teeth, the teeth can push out the material that is blocked or stuck in the screen holes because they penetrate deep into the screen holes. Then the screen frame continues to rotate, driving the material to the brush blocks. The bristles at the end of the brush blocks will brush the material into the crusher body for secondary crushing. The sticky material pushed out by the teeth at the opening of the screen holes is also brushed away by the bristles at the end of the brush blocks, which achieves the effect of cleaning the screen holes.

[0019] 2. This environmentally friendly building material production raw material crushing device reduces dust leakage by setting up a screen frame, baffles, and other structures. The output shaft of the motor drives the drive gear A through a reducer, thereby causing drive gear A and drive gear B to rotate in opposite directions. This causes the internal blade assembly of the crusher to crush the material and drop it vertically onto the inner surface of the screen frame. Since the crusher generates a certain amount of dust during the crushing process, the dust rises during crushing. As the dust rises, it is blocked on both sides by the baffles, preventing a large amount of dust from leaking out and causing harm to the user. The brush blocks and the rotating screen frame play a certain role in blocking the dust, thus reducing dust leakage during crushing. Attached Figure Description

[0025] 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.

[0026] Please see Figures 1-3 A raw material crushing device for the production of environmentally friendly building materials includes a housing 1. A crusher body 2 is fixedly installed inside the housing 1. A reducer 3 is connected to one side of the crusher body 2, and a motor 4 is connected to one side of the reducer 3. The output shaft of the motor 4 is connected to the crusher body 2 through the reducer 3. A screen frame 5 is rotatably installed inside the housing 1. A drive roller 11 and a driven roller 12 are respectively installed on the two sides of the screen frame 5 inside the housing 1. An auxiliary roller 13 is installed on the two sides of the screen frame 5 inside the housing 1. The rotation angle and position of the screen frame 5 are limited by the cooperation between the drive roller 11, the driven roller 12 and the auxiliary roller 13. A transmission device 6 is installed between one side of the crusher body 2 and the drive roller 11.

[0027] In practical applications, this device achieves the cleaning of screen holes 51 by setting up the cooperation between screen frame 5, teeth 14, and brush blocks 54. During the rotation of drive roller 11, screen frame 5 is rotated through teeth 14. Teeth 14 penetrate into the screen hole 51 and push out the material blocked inside the screen hole 51. When the baffle plate 52 drives the material to rotate to the brush block 54, the brush block 54 brushes the material into the crusher body 2 and simultaneously brushes away the sticky material cleared by teeth 14. When screen frame 5 rotates to a certain angle, the material can be screened smoothly.

[0028] By cooperating with the baffle 53 of the screen frame 5 and the housing 1, the dust overflow during crushing is reduced. Users can feed materials through the gap between the baffle 53 and the housing 1. When the crusher body 2 crushes the material, a certain amount of dust will be generated. The dust will rise upward during the movement. By rotating the inner surface of the screen frame 5 and blocking the baffle 53, a large amount of dust can be prevented from overflowing to the outside during crushing, thus reducing the dust overflow effect.

[0029] Please see Figures 1-4 The outer ring of the drive roller 11 is uniformly provided with teeth 14. Rotating blocks 15 are rotatably installed on both sides of the drive roller 11, driven roller 12 and auxiliary roller 13 on the outer and inner arc edges of the screen frame 5. The rotating blocks 15 are used to assist in supporting the position of the screen frame 5 and make the screen frame 5 rotate more smoothly. A gear A16 is provided at the end of the drive roller 11 on one side of the box body 1.

[0030] When the gear A16 is driven to rotate, the drive roller 11 rotates synchronously. Since the teeth 14 mesh with the screen hole 51, the teeth 14 can synchronously drive the screen frame 5 to rotate circumferentially between the drive roller 11, the driven roller 12 and the auxiliary roller 13 during the rotation process, so as to achieve the effect of rotating and screening the crushed material. At the same time, when the teeth 14 mesh with the screen hole 51, the end of the teeth 14 can push out the material blocked inside the screen hole 51, so as to achieve the effect of cleaning the screen hole 51.

[0031] Please see Figures 1-3 The crusher body 2 includes a housing 21, a drive gear A22, and a drive gear B23. A set of cutters is symmetrically and rotatably installed inside the crusher body 2. Housings 21 are provided on both sides of the crusher body 2 to fix and support the position of the crusher body 2. A drive gear A22 and a drive gear B23 are rotatably installed on one side of one housing 21. The drive gear A22 and the drive gear B23 are respectively connected to the cutter set inside the crusher body 2. The drive gear A22 and the drive gear B23 mesh with each other. The drive gear A22 is connected to the output shaft of the reducer 3 for transmission.

[0032] Motor 4 is connected to drive gear A22 via reducer 3. When motor 4 is started, the output shaft of motor 4 drives drive gear A22 to rotate synchronously via reducer 3. Drive gear A22 meshes with drive gear B23, thereby causing the blade assembly inside crusher body 2 to rotate in opposite directions, thus crushing the material.

[0033] Please see Figures 1-4 The surface of the sieve frame 5 is uniformly provided with sieve holes 51 in a circular shape. The cross-section of the sieve hole 51 is trapezoidal. The long side of the sieve hole 51 is longer than the long side of the tooth 14. The short side of the sieve hole 51 is matched with the short side of the tooth 14. The sieve hole 51 and the tooth 14 mesh with each other.

[0034] As the tooth 14 rotates, it drives the screen frame 5 to rotate. Since the long side of the screen hole 51 is larger than the long side of the tooth 14, it will not block the meshing transmission between the tooth 14 and the screen hole 51. This allows the screen frame 5 to rotate smoothly between the drive roller 11, the driven roller 12 and the auxiliary roller 13, so that the drive roller 11 can provide rotational power to the screen frame 5 when it rotates.

[0035] Please see Figures 1-4 The inner surface of the sieve frame 5 is uniformly provided with a ring-shaped baffle 52. The baffle 52 is inclined and can move more unqualified particles. The sieve frame 5 is symmetrically fixedly installed with baffles 53 inside the box 1. The inner ring of the sieve frame 5 is in contact with the outer wall of the baffle 53. Brush blocks 54 are fixedly installed between the baffles 53. The ends of the brush blocks 54 are provided with bristles, which are in contact with the inner surface of the sieve frame 5.

[0036] The crushed material from the crusher body 2 falls vertically onto the inner surface of the screen frame 5 between the deflector plates 52. As the screen frame 5 rotates, the qualified particle size material falls downward through the screen holes 51, while the unqualified particle size material is deflected by the deflector plates 52 and rotates with the screen frame 5. When the unqualified particle size material is deflected by the deflector plates 52 to the position of the teeth 14, the teeth 14 push out the material blocking the screen holes 51, thus cleaning the screen holes 51. The screen frame 5 continues to rotate, and when it moves to the brush block 54, the brush block 54 brushes the material off, causing it to fall vertically downward into the interior of the crusher body 2 for secondary crushing. The sticky substance pushed out by the teeth 14 is also brushed off by the brush block 54, achieving the effect of jointly cleaning the screen holes 51.

[0037] Please see Figures 1-3 The transmission device 6 includes gear B61 and gear C62. Gear B61 and gear C62 are rotatably mounted on one side of the housing 1. Gear B61 meshes with drive gear B23, gear B61 meshes with gear C62, and gear C62 meshes with gear A16. Drive gear A22 is connected to drive gear B23, gear B61, gear C62 and gear A16.

[0038] The transmission device 6 achieves multi-stage transmission through the meshing of gears B61 and C62 with drive gears B23 and A16. Since the output shaft of motor 4 has increased torque after passing through reducer 3, it can simultaneously drive crusher body 2 and teeth 14 to work. When drive gear A22 rotates, it drives drive gear B23 to rotate synchronously. Drive gear B23 transmits power to gear A16 through gears B61 and C62. Gear A16 drives screen frame 5 to rotate through teeth 14.

[0039] Working Principle: During operation, the user feeds the material to be crushed into the box 1 through the gap between the baffle 53 and the box 1. Then, the motor 4 is started. The output shaft of the motor 4 drives the drive gear A22 via the reducer 3, causing the drive gear A22 and drive gear B23 to rotate in opposite directions. This causes the material inside the crusher body 2 to be crushed by the blade assembly and fall vertically onto the inner surface of the screen frame 5. As the drive gear B23 rotates, it drives gear A16 to rotate synchronously through gears B61 and C62. Gear A16, through the meshing of its teeth 14 with the screen holes 51, causes the screen frame 5 to rotate circumferentially between the drive roller 11, driven roller 12, and auxiliary roller 13. The rotation of the screen frame 5 causes the crushed material to pass through the screen evenly. Since the crusher body 2 generates dust during material crushing, the dust rises during the crushing process and is blocked by the baffles on both sides as it rises. The screen frame 54 and brush block 54 work together to block dust and prevent it from leaking out and harming users. The brush block 54 and the rotating screen frame 5 block the dust and reduce its leakage. Qualified materials fall through the screen holes 51, while unqualified materials are rotated synchronously with the screen frame 5 by the pusher plate 52. When the screen frame 5 rotates the material to the teeth 14, the teeth 14, which are deep inside the screen holes 51, can push out the material that is blocked or stuck inside the screen holes 51. Then the screen frame 5 continues to rotate and rotates the material to the brush block 54. The bristles at the end of the brush block 54 will brush the material into the crusher body 2 for secondary crushing. The sticky material pushed out by the teeth 14 at the opening of the screen hole 51 is also brushed away by the bristles at the end of the brush block 54. Through the cooperation of the teeth 14 and the brush block 54, the screen hole 51 is prevented from being blocked and the crushed material can be continuously screened.
