[0001] This utility model relates to the field of construction waste treatment technology, specifically to a crushing device for construction waste. Background Technology

[0002] Construction waste crushing and re-sorting is a key environmental protection project. Its main purpose is to crush construction waste and then sort and classify it for further recycling.

[0003] A search revealed that Chinese patent CN218590629U discloses a construction solid waste treatment device. Solid waste is poured into a chamber, and then a crushing device is activated to crush the solid waste. The crushed waste then falls into a fixed cylinder through a connecting pipe connected to a feeding plate. At this time, the first motor is activated, and the feeding auger agitates and feeds the solid waste while simultaneously filtering smaller pieces through a filter plate. Finally, the waste is discharged from the discharge pipe. The feeding auger transports larger pieces of solid waste from the discharge port to a hopper. This device effectively reduces the gaps between stacked materials, increases the volume of each transport, and improves the speed of waste treatment and transportation.

[0004] Regarding the relevant technologies of the aforementioned patents, the inventors have discovered that the aforementioned patents still have at least the following shortcomings: certain materials in construction waste, such as limestone, gypsum, and bricks, are easily broken into fine particles during the crushing process, thereby generating dust and causing pollution to the outside world. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a crushing device for construction waste, which solves the problem that the above-mentioned patents cannot handle the dust generated when crushing construction waste.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A crushing device for construction waste includes a processing box and a feed inlet disposed on one side of the processing box. A filter screen is detachably installed on the top of the processing box, and a fan is fixedly installed on the other side of the processing box. A collection cover is installed through a pipe at the air inlet of the fan, and the collection cover is rotatably connected to the pipe. The collection cover is located on top of the filter screen.

[0009] The top of the processing box has two L-shaped plates symmetrically arranged along its axis. The filter screen is placed between the two L-shaped plates. Insertion holes are opened on both sides of the filter screen. Insert rods are slidably connected inside the L-shaped plates, and the outer diameter of the insert rods is adapted to the inner diameter of the insertion holes. A movable plate is fixedly connected to the end of the insert rod away from the filter screen. A first reset member is connected between the outer wall of the movable plate and the inner wall of the processing box. A button is provided on the side of the movable plate away from the filter screen.

[0010] Preferably, the top of the filter screen is symmetrically equipped with handles.

[0011] Preferably, a sliding plate is fixedly connected to the bottom of the movable plate, and a wedge is fixedly connected to the top of the sliding plate.

[0012] Preferably, a pressing rod is fixedly installed at the bottom of the button, the bottom end of the pressing rod is located at the top of the wedge-shaped inclined surface, and the pressing rod is slidably connected to the processing box.

[0013] Preferably, a retaining ring is connected to the outer wall of the extrusion rod, and a second resetting member is connected between the outer wall of the retaining ring and the inner wall of the processing box.

[0014] Furthermore, a rotating shaft is fixedly installed inside the feed inlet, and a baffle is rotatably connected to the outside of the rotating shaft via a torsion spring.

[0015] Preferably, a receiving box is slidably connected to the bottom of the processing box, and a handle is fixedly installed on the outer wall of the receiving box.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. In this utility model, before feeding materials through the inlet, the blower is turned on to operate. The collection hood sucks up the dust generated during material feeding and crushing.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] This utility model discloses a crushing device for construction waste.

[0030] This utility model provides, for example Figure 1-6The construction waste crushing device shown includes a processing box 1 and a feed inlet 2 located on one side of the processing box 1. A crushing mechanism is installed on the processing box 1. The crushing mechanism includes a drive motor installed on the outer wall of the processing box 1, a pair of crushing rollers rotatably arranged in the inner cavity of the processing box 1, and a gear set between the drive motor and the crushing rollers. A filter screen 3 is detachably installed on the top of the processing box 1. A fan 4 is fixedly installed on the other side of the processing box 1. A collection cover 5 is installed through a pipe at the air inlet of the fan 4. The collection cover 5 is rotatably connected to the pipe and is located on top of the filter screen 3.

[0031] Two L-shaped plates 6 are symmetrically arranged on the top of the processing box 1 along its axis. The filter screen 3 is placed between the two L-shaped plates 6. Insertion holes 7 are opened on both sides of the filter screen 3. Insertion rods 8 are slidably connected inside the L-shaped plates 6. Through holes for the insertion rods 8 to move are opened through the wall of the L-shaped plates 6. The outer diameter of the insertion rods 8 is matched with the inner diameter of the insertion holes 7. A movable plate 9 is fixedly connected to the end of the insertion rods 8 away from the filter screen 3. A first reset member 10 is connected between the outer wall of the movable plate 9 and the inner wall of the processing box 1. A button 11 is provided on the side of the movable plate 9 away from the filter screen 3.

[0032] Specifically, the first reset member 10 can be selected as a spring according to the actual situation, so that the subsequent insertion rod 8 can be disengaged from the insertion hole 7. After the filter screen 3 is removed, the insertion rod 8 will automatically reset under the elastic action of the first reset member 10.

[0033] Specifically, before feeding materials through the feed inlet 2, the blower 4 is turned on to operate. The collection hood 5 is used to suck up the dust generated when the materials are fed and crushed. The dust is filtered through the filter screen 3 and then discharged to the outside, reducing or avoiding dust pollution to the external environment. When the filter screen 3 needs to be cleaned later, press any button 11 to disengage one of the inserts 8 from the insertion hole 7 of the filter screen 3, and the filter screen 3 can be removed from the top of the processing box 1. The operation is convenient.

[0034] To improve the practicality of this device, such as Figure 4 , Figure 6 As shown, handles are symmetrically installed on the top of the filter screen 3; a slide plate 12 is fixedly connected to the bottom of the movable plate 9, and a wedge block 13 is fixedly connected to the top of the slide plate 12; a pressing rod 14 is fixedly installed on the bottom of the button 11, the bottom end of the pressing rod 14 is located at the top of the inclined surface of the wedge block 13, and the pressing rod 14 is slidably connected to the processing box 1.

[0035] Specifically, pressing button 11 causes the squeezing rod 14 to move downward. The bottom end of the squeezing rod 14 moves vertically downward and contacts the inclined surface of the wedge block 13, pushing the wedge block 13 to move away from the L-shaped plate 6. This causes the slide plate 12 and the moving plate 9 to move synchronously and compress the first reset member 10, causing the insertion rod 8 to disengage from the insertion hole 7 and releasing the restriction on the filter screen 3. The linkage is strong.

[0036] like Figure 6 As shown, a retaining ring 15 is connected to the outer wall of the extrusion rod 14, and a second reset member 16 is connected between the outer wall of the retaining ring 15 and the inner wall of the processing box 1.

[0037] Specifically, the second reset member 16 can be selected as a spring according to the actual situation, so that after the downward pressure applied to the button 11 is released, the fixing ring 15 will drive the squeezing rod 14 and the button 11 to automatically reset under the elastic action of the second reset member 16.

[0038] In order to improve the functionality of this device, such as Figure 2 , Figure 3 As shown, a rotating shaft 17 is fixedly installed inside the feed inlet 2, and a baffle 19 is rotatably connected to the outside of the rotating shaft 17 via a torsion spring 18.

[0039] Specifically, after the material is fed into the feed inlet 2, the material's gravity pushes the baffle 19 to rotate into the inner cavity of the processing box 1, causing the material to fall into the inner cavity of the processing box 1 and be crushed. The baffle 19 is reset under the elastic action of the torsion spring 18, blocking the feed inlet 2 and preventing dust from drifting to the outside from the feed inlet 2.

[0040] like Figure 2 As shown, a receiving box 20 is slidably connected to the bottom of the processing box 1, and a handle is fixedly installed on the outer wall of the receiving box 20.

[0041] Specifically, after a batch of materials is crushed, they all fall into the receiving box 20. The receiving box 20 can be pulled out from the bottom of the processing box 1 using the handle.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
