Description

Technical Field

[0001] This utility model relates to the field of waste treatment and recycling technology, and in particular to a high-efficiency construction waste crusher. Background Technology

[0002] A crusher is a pulverizing machine used in the processing of metal and non-metal minerals to crush mined raw ore into small particles through compression and bending.

[0003] Existing crushers, especially jaw crushers, crush building materials between the moving and stationary jaw plates by repeatedly pressing the moving jaw plate against the stationary jaw plate. However, the following problems exist during use:

[0004] 1. In a jaw crusher, the moving jaw plate is driven to reciprocate by a pusher plate. Uncrushed particles fall through the gap between the moving and stationary jaw plates when the moving jaw plate moves away from the pusher plate. This results in the finished product being mixed with large particles that do not meet recycling requirements. Furthermore, existing crushers do not consider real-time sorting during the crushing process, requiring secondary screening of the crushed material particles. Additionally, oversized particles need to be crushed again, making the process cumbersome and severely reducing the efficiency of crushing and sorting.

[0005] 2. Building materials often contain various plastic products, resulting in the finished product collected by the crusher containing lightweight plastic products. Since the stone particles obtained after crushing are often used for paving or reprocessing into bricks, existing crushers still need to check whether the finished product contains plastic products after crushing, which increases the workload of workers. Utility Model Content

[0006] In order to solve the above problems, the purpose of this utility model is to provide a high-efficiency construction waste crusher, which aims to solve the problem that the particle size difference in the finished product after crushing by existing crushers is too large, thereby reducing the crushing and sorting efficiency.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A high-efficiency construction waste crusher includes a frame, a feeding port located at the top of the frame, a crushing component movably located in the upper part of the frame for crushing stone waste, a screening component rotatably located in the frame below the crushing component for screening crushed particles of different sizes, a separation component located in the frame in front of the screening component for separating plastic products from the crushed particles, and a collection component located in the frame behind the screening component for collecting the screened crushed particles.

[0009] The crushing assembly includes a stationary jaw plate fixedly disposed on one side of the inner wall of the frame, a movable jaw plate movably disposed on the other side of the inner wall of the frame opposite to the stationary jaw plate, a crushing opening disposed between the stationary jaw plate and the movable jaw plate, and a drive sub-assembly fixedly disposed on the frame and used to drive the movable jaw plate to move toward the stationary jaw plate and crush the waste at the crushing opening.

[0010] The screening assembly includes a screening plate detachably connected to the inner wall of the frame and located below the crushing port; a rotating column rotatably mounted on the screening plate along the axial direction; a control motor fixedly mounted on the lower part of the screening plate and used to drive the rotating column to rotate; a number of fixed columns arranged circumferentially and spaced apart on the side wall of the rotating column; a number of spreading rods rotatably mounted on the side wall of the fixed column corresponding to each fixed column and used to spread the particles on the screening plate; a number of turning strips arranged circumferentially and spaced apart on the side wall of the spreading rod and used to flip over excessively large particles on the screening plate; and a number of rotating motors fixedly mounted on the fixed columns corresponding to each fixed column and used to drive the spreading rod to rotate.

[0011] The front end of the screening plate is tilted downwards;

[0012] The collection assembly includes a conveyor belt that is movably positioned below the screening plate and conveys crushed particles to the rear end, and a collection bin located at the rear end of the conveyor belt.

[0013] More preferably, the separation assembly includes a collection box fixedly disposed at the front end of the screening plate for collecting broken particles with excessive diameter, a plurality of ventilation slots arranged at intervals at the bottom of the collection box, a blower disposed below the ventilation slots for blowing the plastic in the collection box upward, and a receiving chamber disposed at the top of the collection box for collecting the plastic.

[0014] More preferably, the storage box has a hinged cover at the front end and a retrieval door hinged to the side wall of the storage box at the receiving cavity.

[0015] More preferably, the upper surface edge of the screening plate is provided with a surrounding ring for preventing particles from falling off the screening plate, and the front end of the surrounding ring is provided with an opening.

[0016] More preferably, the output shaft of the rotating motor is axially fixedly connected to the spreading bar, and a protective cover is fixedly provided on the side wall of the turnover column above the rotating motor.

[0017] More preferably, the frame is fixedly provided with abutment plates on opposite sides, and the side walls of the screening plate are respectively provided with mounting plates corresponding to the abutment plates on both sides. Each mounting plate is detachably connected with a fastening rod for fastening the abutment plate and the mounting plate.

[0018] More preferably, the drive sub-assembly includes an eccentric shaft rotatably mounted on the frame and extending through the upper part of the moving jaw plate in the left-right direction, a pair of pulleys fixed at both ends of the eccentric shaft, a drive motor fixed at the rear of the frame for driving the pulleys to rotate, a thrust plate fixed at the lower part of the moving jaw plate, and an adjustment block fixed at the rear end of the thrust plate and fixedly connected to the inner wall of the frame.

[0019] The axis of the eccentric shaft is offset from the center of the pulley.

[0020] This utility model has the following beneficial effects:

[0021] 1. This utility model allows the particles after being crushed by the crushing component to fall onto the screening plate. The crushed particles with the required diameter fall through the sieve holes of the screening plate into the collection component. The crushed particles that are too large cannot pass through the screening plate and fall out from the opening into the separation component. The operator only needs to open the opening and closing cover after a period of time to take out the large particles of waste in the collection box and pour them into the feeding port for secondary crushing. This solves the problem that the stones with the larger particle size cannot be automatically screened out in the finished product after crushing.

[0022] 2. This utility model accelerates the screening speed by controlling a motor to drive a rotating column when screening particles of different diameters. This is achieved by spreading the crushed particles on the screening plate evenly with a spreading rod. During the spreading process, the waste particles that are too large are continuously turned over, causing the smaller diameter waste on the surface of the larger diameter waste to be shaken off. This solves the problem that when large diameter waste particles fall into the separation component, some small particles adhere to the surface of the large diameter waste particles, resulting in the mixing of qualified small diameter crushed particles into the separation component.

[0023] 3. This utility model achieves the effect of separating plastic products mixed in with large-diameter waste by continuously blowing air through the large-diameter granular waste during the process of large-diameter waste entering the collection box and blowing the plastic products into the collection chamber.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment of a high-efficiency construction waste crusher includes a frame 1, a feeding port 2 located at the top of the frame 1, a crushing component 3 movably located in the upper part of the frame 1 for crushing stone waste, a screening component 4 rotatably located in the frame 1 and below the crushing component 3 for screening out crushed particles of different sizes, a separation component 5 located inside the frame 1 and in front of the screening component 4 for separating plastic products from the crushed particles, and a collection component 6 located inside the frame 1 and behind the screening component 4 for collecting the screened crushed particles.

[0032] The crushing assembly 3 includes a stationary jaw plate 31 fixedly disposed on one side of the inner wall of the frame 1, a movable jaw plate 32 movably disposed on the other side of the inner wall of the frame 1 opposite to the stationary jaw plate 31, a crushing opening 33 disposed between the stationary jaw plate 31 and the movable jaw plate 32, and a drive sub-assembly 34 fixedly disposed on the frame 1 and used to drive the movable jaw plate 32 to move toward the stationary jaw plate 31 and crush the waste located at the crushing opening 33.

[0033] The screening assembly 4 includes a screening plate 41 detachably connected to the inner wall of the frame 1 and located below the crushing port 33; a rotating column 42 rotatably mounted on the screening plate 41 along the axial direction; a control motor 43 fixedly mounted on the lower part of the screening plate 41 and used to drive the rotating column 42 to rotate; a plurality of fixed columns 44 arranged circumferentially and spaced apart on the side wall of the rotating column 42; a plurality of spreading rods 45 rotatably mounted on the side wall of the fixed column 44 corresponding to each fixed column 44 and used to spread the particles on the screening plate 41; a plurality of turning strips 46 arranged circumferentially and spaced apart on the side wall of the spreading rods 45 and used to flip over the oversized particles on the screening plate 41; and a plurality of rotating motors 47 fixedly mounted on the fixed column 44 corresponding to each fixed column 44 and used to drive the spreading rods 45 to rotate.

[0034] The front end of the screening plate 41 is tilted downwards;

[0035] The collection component 6 includes a conveyor belt 61 that is movably disposed below the screening plate 41 and conveys crushed particles to the rear end, and a collection box 62 disposed at the rear end of the conveyor belt 61.

[0036] When using this product, the drive motor 34 is started, which moves the moving jaw plate 32, allowing construction waste to be poured into the frame 1 through the feed inlet 2. The construction waste is crushed by the moving jaw plate 32 in the crushing inlet 33. The crushed particles fall downwards through the crushing inlet 33 onto the screening plate 41. The control motor 43 is then started, causing the rotating column 42 to rotate. This causes the spreading rod 45 to evenly distribute the crushed particles on the screening plate 41, ensuring a uniform distribution of the particles. This allows small particles of waste to fall through the holes of the screening plate 41, accelerating the crushing process. The screening efficiency is achieved by having crushed particles pass through the screening plate 41 and fall onto the conveyor belt 61, where they are collected in the collection box 62 along the conveying direction. Oversized crushed particles cannot pass through the screen holes of the screening plate 41 and are thus subjected to the pushing force of the spreading rod 45. They move together with the rotating spreading rod 45. During the contact process, the spreading rod 45 rotates, causing the turning bar 46 to come into contact with the crushed particles and apply a turning pushing force to the crushed particles. This causes the large-diameter waste to turn over, causing the small crushed particles accumulated on its surface to fall off, thereby completely separating the oversized crushed particles from the appropriately sized crushed particles.

[0037] like Figure 2 and Figure 5 As shown, the separation component 5 includes a collection box 51 located at the front end of the screening plate 41 for collecting particles with excessive diameter and plastic, several ventilation slots 52 arranged at intervals at the bottom of the collection box 51, a blower 53 located below the collection box 51 for blowing the plastic inside the collection box 51 upwards, and a receiving chamber 54 located at the top of the collection box 51 for collecting plastic.

[0038] When this product is in use, large crushed particles fall from the front end of the screening plate 41 as the spreading bar 45 rotates, and fall into the collection box 51. Inside the collection box 51, the blower 53 blows air from the ventilation channel 52, causing the lightweight plastic products mixed in with the large crushed particles to be blown upward by the air force, thereby blowing the plastic products into the receiving chamber 54, achieving the separation of plastic and building stone.

[0039] like Figure 1 and Figure 5 As shown, the storage box 51 is hinged to the front end with an opening and closing cover 7, and the storage box 51 is hinged to the side wall at the location corresponding to the receiving cavity 54 with a retrieval door 8.

[0040] When using this product, the large-diameter crushed particles in the storage box 51 can be taken out by opening the opening and closing cover 7, and the plastic products in the receiving chamber 54 can be taken out separately by opening the retrieval door 8, thus facilitating the separate recycling operation of plastic products.

[0041] like Figure 2 , Figure 3 and Figure 4 As shown, the upper surface edge of the screening plate 41 is provided with a surrounding ring 9 to prevent particles from falling off the screening plate 41, and the front end of the surrounding ring 9 is provided with an opening 10.

[0042] When using this product, the surrounding ring 9 prevents the crushed particles from falling off the edge of the screen plate 41 due to excessive crushed particles when the spreading bar 45 is rotating and spreading the crushed particles.

[0043] like Figure 3 and Figure 4 As shown, the output shaft of the rotating motor 47 is axially fixedly connected to the spreading bar 45, and a protective cover 11 is fixedly provided on the side wall of the turnover column 42 above the rotating motor 47.

[0044] When this product is in use, after the crushed particles fall out of the crushing port 33, some of the crushed particles directly hit the protective cover 11, thereby preventing the crushed particles from hitting the rotating motor 47 and causing damage to the rotating motor 47.

[0045] like Figure 4 As shown, abutment plates 12 are fixedly provided on opposite sides inside the frame 1, and mounting plates 13 are provided on both sides of the side wall of the screening plate 41 corresponding to the abutment plates 12 on both sides. Each mounting plate 13 is detachably connected with a fastening rod 14 for fastening the abutment plate 12 and the mounting plate 13.

[0046] When using this product, the mounting plates 13 on both sides of the screening plate 41 are aligned with the abutment plates 12 on both sides inside the frame 1. The mounting plates 13 and abutment plates 12 are then connected by fastening rods 14 to fix the screening plate 41 to the frame 1. This achieves the effect of replacing the screening plate 41, so that different screening diameters can be adjusted by replacing different screening plates 41.

[0047] like Figure 1 and Figure 2 As shown, the drive sub-assembly 34 includes an eccentric shaft 341 rotatably mounted on the frame 1 and passing through the upper part of the moving jaw plate 32 in the left-right direction, a pair of pulleys 342 fixed at both ends of the eccentric shaft 341, a drive motor 343 fixed at the rear of the frame 1 and used to drive the pulleys 342 to rotate, a thrust plate 344 fixed at the lower part of the moving jaw plate 32, and an adjustment block 345 fixed at the rear end of the thrust plate 344 and fixedly connected to the inner wall of the frame 1.

[0048] The axis of the eccentric shaft 341 is offset from the center of the pulley 342.

[0049] When using this product, the operator turns on the drive motor 343, causing the output shaft of the drive motor 343 to rotate and drive the pulley 342 to rotate accordingly. This causes the eccentric shaft 341 to rotate eccentrically, causing the movable jaw plate 32 to repeatedly move closer to or further away from the stationary jaw plate 31 under the action of the eccentric shaft 341, thereby crushing the waste at the crushing opening 33. The size of the crushed particles can be changed by adjusting the distance between the adjusting block 345 and the movable jaw plate 32.

[0050] The working principle of this device is as follows:

[0051] Step 1: Start the drive motor 343 to move the moving jaw plate 32 and pour the construction waste into the frame 1 through the feed port 2. The construction waste is crushed by the pressure of the moving jaw plate 32 in the crushing port 33. The crushed particles fall down through the crushing port 33 and onto the screening plate 41.

[0052] Step 2: Start the control motor 43, which drives the rotating column 42 to rotate, so that the spreading bar 45 spreads the crushed particles placed on the screening plate 41 evenly, so that the crushed particles are evenly distributed on the surface of the screening plate 41, and the small particles of waste fall from the holes of the screening plate 41, which speeds up the screening efficiency. The crushed particles that pass through the screening plate 41 fall onto the conveyor belt 61 and fall into the collection box 62 along the conveying direction to be collected.

[0053] Step 3: Oversized crushed particles cannot pass through the screen holes of the screening plate 41, and are thus subjected to the pushing force of the spreading bar 45. They move together with the rotating spreading bar 45. During the contact process, the rotating motor 47 is started at the same time, driving the pushing bar 45 to rotate. Due to the rotation of the spreading bar 45, the turning bar 46 comes into contact with the crushed particles and applies a turning pushing force to the crushed particles, causing the large-diameter waste to turn over and the small crushed particles accumulated on its surface to fall off.

[0054] Step 4: As the large crushed particles rotate with the spreading bar 45, they fall out of the opening 10 and into the collection box 51. Inside the collection box 51, they are blown by the air force from the blower 53 through the ventilation channel 52. This causes the lightweight plastic products mixed in with the large crushed particles to be blown upwards by the air force, thereby blowing the plastic products into the receiving chamber 54, achieving the separation of plastic from building stones.

[0055] Step 5: After a period of time, open the cover 7 to take out the large-diameter granular waste in the storage box 51, and pour it back in through the feed port 2. It will be repeatedly crushed by the crushing component 3, so that the crushed particles are completely crushed.

[0056] Step 6: The operator opens the retrieval door 8, removes the plastic products from the receiving chamber 54, and performs a separate recycling operation.

[0057] The above description is only a specific embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
