Description

Technical Field

[0001] The utility model relates to the technical field of waste crushing, in particular to a construction waste crushing mechanism and a construction waste crushing production line. Background Art

[0002] At present, in the relevant technology, most of the existing construction waste crushing devices are a single crushing process, which reduces the crushing effect. The volume and mass of the waste are too large, making it inconvenient to collect and process. At the same time, the existing construction waste crushing device crushes the construction waste and directly drops it to the discharge port for discharge, which easily causes damage to the device and reduces its service life. In view of these problems, it is very necessary to design a construction waste crushing device that can crush the waste multiple times and buffer the falling waste. The existing buffering of construction waste is achieved by the waste falling on the screen plate and the compression and rebound of the elastic components on both sides of the screen plate. However, over time, the working function of the elastic component decreases and the buffering effect is reduced, so that the screen plate is bent and deformed by the falling waste. Therefore, it is very important to facilitate the disassembly and replacement of the elastic component and the screen plate.

[0003] The existing patent (publication number: CN221360355U) proposes a construction waste crushing device, including a box body and a sieve plate arranged horizontally in the box body and movable up and down, support plates are provided on both sides of the sieve plate, and the two opposite side walls of the box body are penetrated by slide grooves for the two support plates to be horizontally plugged in and slide up and down respectively, the support plates extend beyond the outer wall of the box body and an elastic support mechanism is provided between the extending part and the outer wall of the box body so that the support plates have a tendency to bounce upward. The construction waste crushing device of the utility model uses the support plate as a connecting part to place the elastic support mechanism outside the box body, which can effectively prevent dust raised in the box body from entering the movable parts of the elastic support mechanism, so as to avoid the up and down movement of the sieve plate being obstructed, thereby reducing the attenuation rate of the buffering performance of the sieve plate.

[0004] The above-mentioned technical solution to solve the problem of reducing the attenuation rate of the buffering performance of the screen plate adopts a method of placing the elastic support mechanism on the outside of the box body through a support plate as a connecting part, which can effectively prevent the dust raised in the box body from entering the movable parts of the elastic support mechanism, so as to avoid the up and down movement of the screen plate being obstructed. Although this solution can avoid the problem of obstruction of the up and down movement of the screen plate, when the elastic component has been used for a long time, the buffering performance becomes weak, which will cause the screen plate to deform and the working efficiency of the elastic component to decrease. The device is inconvenient to disassemble and replace the screen plate and the elastic component, so we propose a construction waste crushing mechanism to solve the above problems. Utility Model Content

[0005] The utility model provides a construction waste crushing mechanism, which solves the technical problem that elastic components in current construction waste crushing devices are difficult to disassemble and replace.

[0006] In order to solve the above technical problems, the utility model provides a construction waste crushing mechanism, including a crushing box and a screen plate arranged in the crushing box and movable up and down, the crushing box also includes a lower half box and an upper half box, and lifting mechanisms are provided on both sides of the lower half box and the upper half box, and movable openings are opened on the other two sides of the lower half box and the upper half box, and the screen plate is arranged in the crushing box, and brackets are detachably provided at both ends of the screen plate near the movable opening, and the movable opening is extended out of the crushing box at one end of the bracket away from the screen plate, and an upper clamping plate is fixed to the end of the bracket away from the screen plate, and a lower clamping plate is fixed on the lower half box, and an elastic component is clamped between the upper clamping plate and the lower clamping plate, and bolts are provided on both the upper clamping plate and the lower clamping plate, and the elastic component is fixed between the upper clamping plate and the lower clamping plate by bolts.

[0007] Preferably, the elastic component includes a spring, a telescopic rod is sleeved inside the spring, an upper clamping block is fixed to the top of the spring and the telescopic rod, and a lower clamping block is fixed to the bottom of the spring and the telescopic rod. The bottom of the upper clamping plate and the top of the lower clamping plate are both provided with clamping slots, the upper clamping block is clamped in the clamping slot opened at the bottom of the upper clamping plate, and the lower clamping block is clamped in the clamping slot opened at the top of the lower clamping plate.

[0008] The above technical solution is adopted: the elastic component includes a spring, a telescopic rod is provided inside the spring, an upper clamping block is fixed to the top of the spring and the telescopic rod, and a lower clamping block is fixed to the bottom of the spring and the telescopic rod. The bottom of the upper clamping plate and the top of the lower clamping plate are both provided with a slot, the upper clamping block is clamped in the slot opened at the bottom of the upper clamping plate, and the lower clamping block is clamped in the slot opened at the top of the lower clamping plate. The elastic component can form a buffer for the construction waste falling on the screen plate when the construction waste enters the crushing box for crushing, thereby preventing damage to the screen plate. At the same time, after long-term use, the elasticity of the elastic component will decrease, resulting in poor buffering effect and the need for replacement. The elastic component is clamped between the upper clamping plate and the lower clamping plate, which is more convenient for disassembly and installation.

[0009] Preferably, the lifting mechanism includes a lifting column, a first fixing block is fixed to the top of the lifting column, a second fixing block is fixed to the bottom of the lifting column, the first fixing block is fixed to the upper half box, and the second fixing block is fixed to the lower half box.

[0010] The above technical solution is adopted: the lifting mechanism includes a lifting column, a first fixed block is fixed to the top of the lifting column, and a second fixed block is fixed to the bottom of the lifting column. The first fixed block is fixed to the upper half box, and the second fixed block is fixed to the lower half box. The upper half box and the lower half box are separated by the lifting of the lifting mechanism, thereby facilitating the disassembly and replacement of the sieve plate in the crushing box.

[0011] Preferably, the bracket is L-shaped, and the width of the bracket is smaller than the width of the movable opening.

[0012] The above technical solution is adopted: the bracket is L-shaped, and the width of the bracket is smaller than the width of the movable opening, so that when the construction waste falls on the screen plate, the screen plate is fixed on the bracket. When the width of the bracket is smaller than the width of the movable opening, the bracket can move up and down in the movable opening, so that the screen plate can move up and down under the buffering of the spring, thereby achieving a buffering effect.

[0013] Preferably, a baffle is sleeved on the bracket.

[0014] The above technical solution is adopted: a baffle is sleeved on the bracket, and the baffle can prevent a large amount of dust in the crushing box from overflowing from the movable opening.

[0015] Preferably, the width of the baffle is the same as that of the movable opening, and the length of the baffle is greater than that of the movable opening.

[0016] The above technical solution is adopted: the width of the baffle is the same as the movable opening, and the length of the baffle is greater than the length of the movable opening. When the screen plate moves up and down, the baffle also moves up and down. Since the width of the baffle is the same as the movable opening, and the length of the baffle is greater than the length of the movable opening, the baffle always blocks the movable opening relative to the movable opening, thereby preventing the crushed construction waste in the crushing box from floating out of the movable opening.

[0017] Preferably, a feed port is provided on the top of the upper half box.

[0018] Adopting the above technical solution: a feeding port is provided on the top of the upper half box to facilitate pouring of construction waste from the feeding port.

[0019] The present application also provides a construction waste crushing production line, which includes the construction waste crushing mechanism.

[0020] Compared with the related art, the present invention has the following beneficial effects:

Compared with the traditional waste crushing device, the utility model is provided with a lifting mechanism and the crushing box is divided into an upper half box and a lower half box, the top of the elastic component is threadedly connected to the screen plate in the crushing box through a bracket, and the bottom of the elastic component is bolted to one side of the crushing box. Then, after the crushing and screening device has been used for a long time, the effect of the elastic component used to cushion the construction waste falling on the screen plate during screening will be greatly reduced, and the screen plate that has been deformed by impact or blocked by some construction waste after long-term use needs to be replaced. The operation is to start the lifting mechanism, lift the upper half box of the crushing box, and then remove the screen plate, which can be taken out from between the upper half box and the lower half box, and then remove the bolts on the upper card plate and the lower card plate, so that the buffer component can be completely taken out from between the upper card plate and the lower card plate, which is easy to disassemble and replace, and the operation is simple, fast and convenient.

A movable opening 13 is opened on the other two sides of the lower half box 11 and the upper half box 12. The sieve plate 2 is arranged in the crushing box 1. The two ends of the sieve plate 2 near the movable opening 13 are detachably provided with brackets 4. One end of the bracket 4 away from the sieve plate 2 extends out of the movable opening 13 outside the crushing box 1. An upper clamping plate 8 is fixed to the end of the bracket 4 away from the sieve plate 2. A lower clamping plate 7 is fixed on the lower half box 11.

The elastic component 6 is fixed between the upper clamping plate 8 and the lower clamping plate 7 by the bolts 10.

[0030] The crushing box 1 also includes a lower half box 11 and an upper half box 12. A lifting mechanism 3 is provided on both sides of the lower half box 11 and the upper half box 12. A movable opening 13 is opened on the other two sides of the lower half box 11 and the upper half box 12. The sieve plate 2 is arranged in the crushing box 1. The two ends of the sieve plate 2 near the movable opening 13 are detachably provided with a bracket 4. The end of the bracket 4 away from the sieve plate 2 extends out of the movable opening 13 outside the crushing box 1. An upper card plate 8 is fixed to the end of the bracket 4 away from the sieve plate 2. A lower card plate 7 is fixed on the lower half box 11. An elastic component 6 is clamped between the upper card plate 8 and the lower card plate 7. Bolts 10 are provided on the upper card plate 8 and the lower card plate 7. The elastic component 6 is fixed between the upper card plate 8 and the lower card plate 7 by the bolts 10. By providing a lifting mechanism 3 and dividing the crushing box 1 into the upper half box 12 and the lower half box 11, the crushing box 1 can be crushed. The top of the elastic component 6 is threadedly connected to the sieve plate 2 in the crushing box 1 through the bracket 4, and the bottom bolt 10 of the elastic component 6 is fixed to one side of the crushing box 1. Then, after the crushing and screening device has been used for a long time, the effect of the elastic component 6 used to cushion the construction waste falling on the sieve plate 2 during screening will be greatly reduced, and the sieve plate 2 that has been deformed by impact or blocked by some construction waste after long-term use needs to be replaced. The operation is to start the lifting mechanism 3, lift the upper half box 12 of the crushing box 1 upward, and then remove the sieve plate 2.

The upper clamping block 63 is clamped in the clamping slot 9 opened at the bottom of the upper card plate 8, and the lower clamping block 64 is clamped in the clamping slot 9 opened at the top of the lower card plate 7. The lifting mechanism 3 includes a lifting column 31, a first fixed block 32 is fixed to the top of the lifting column 31, a second fixed block 33 is fixed to the bottom of the lifting column 31, the first fixed block 32 is fixed to the upper half box 12, and the second fixed block 33 is fixed to the bottom of the lifting column 31. Fixed on the lower half box 11, the bracket 4 is L-shaped, the width of the bracket 4 is smaller than the width of the movable opening 13, and a baffle 5 is sleeved on the bracket 4. The width of the baffle 5 is the same as that of the movable opening 13, and the length of the baffle 5 is greater than the length of the movable opening 13. When the sieve plate 2 moves up and down, the baffle 5 also moves up and down. Since the width of the baffle 5 is the same as that of the movable opening 13 and the length of the baffle 5 is greater than the length of the movable opening 13, the baffle 5 always blocks the movable opening 13 relative to the movable opening 13, thereby preventing the crushed construction waste in the crushing box 1 from floating out of the movable opening 13. A feeding port 14 is provided on the top of the upper half box 12 to facilitate the pouring of construction waste from the feeding port 14;

[0033] A telescopic rod 62 is sleeved in the spring 61, and an upper clamping block 63 is fixed to the top of the spring 61 and the telescopic rod 62, and a lower clamping block 64 is fixed to the bottom of the spring 61 and the telescopic rod 62. A clamping slot 9 is provided at the bottom of the upper clamping plate 8 and the top of the lower clamping plate 7. The upper clamping block 63 is clamped in the clamping slot 9 opened at the bottom of the upper clamping plate 8, and the lower clamping block 64 is clamped in the clamping slot 9 opened at the top of the lower clamping plate 7. The elastic component 6 can form a buffer for the construction waste falling on the sieve plate 2 when the construction waste enters the crushing box 1 for crushing, thereby preventing the sieve plate 2 from being damaged. At the same time, after the elastic component 6 has been used for a long time, its elasticity will be reduced, resulting in a poor buffering effect and the need for replacement. The elastic component 6 is clamped between the upper clamping plate 8 and the lower clamping plate 7, which is more convenient for disassembly and installation;

[0034] The lifting mechanism 3 includes a lifting column 31, a first fixed block 32 is fixed to the top of the lifting column 31, and a second fixed block 33 is fixed to the bottom of the lifting column 31.

By lifting and lowering the lifting mechanism 3, the upper half box 12 is separated from the lower half box 11, thereby facilitating the disassembly and replacement of the sieve plate 2 in the crushing box 1.

[0035] Example 3

[0036] Based on Example 1 or Example 2

[0037] This embodiment further provides a construction waste crushing production line, which includes the construction waste crushing mechanism of the first or second embodiment.

[0038] Working principle: Figure 1-4 When the sieve plate 2 and the elastic component 6 are damaged and need to be replaced, the lifting column 31 in the lifting mechanism 3 is started to lift and separate the upper half box 12 and the lower half box 11 in the crushing box 1, and then the bolts 10 on the sieve plate 2 and the bracket 4 are removed to remove the sieve plate 2 from the bracket 4 and take it out from between the lower half box 11 and the upper half box 12.

When installing the replaced sieve plate 2 and elastic component 6, first clamp the new elastic component 6 between the lower card plate 7 and the upper card plate 8, and then fix the elastic component 6 between the lower card plate 7 and the upper card plate 8 with the bolts 10. After assembly, the new sieve plate 2 is placed on the bracket 4 in the crushing box 1 along the gap between the lower half box 11 and the upper half box 12, and then fix the sieve plate 2 on the bracket 4 with the bolts 10, which is convenient for disassembly and replacement.
