Description

Technical Field

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

[0002] Construction waste mainly includes concrete blocks, gravel, brick and tile fragments, waste mortar, mud, asphalt blocks, waste metal, and waste wood. If it is directly transported and landfilled, it will not only pollute the environment but also waste resources. However, after being crushed and processed, it can be used for paving roads, building houses, and painting, thus achieving secondary utilization.

[0003] In existing technologies, construction waste is generally crushed into fine particles using a construction waste crusher. The top of the construction waste crusher has a feed inlet and a matching crushing roller inside. Most construction waste can be directly crushed by the crushing roller after entering through the feed inlet. However, some construction waste with specific shapes (such as cylindrical or spherical shapes) will roll on the crushing roller as it rotates, making it difficult to be crushed. This waste will also affect the crushing of other construction waste that is subsequently fed in, thereby reducing the crushing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a novel construction waste crushing device to address the problems raised in the background described above.

[0016] 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.

[0017] Example: Please refer to Figures 1 to 3 A novel construction waste crushing device includes a casing 1. Two interlocking crushing rollers 13 are rotatably mounted inside the casing 1. A crushing motor (not shown in the figure) is installed outside the casing 1 to drive the crushing rollers 13. A feed inlet 12 is connected to the top of the casing 1, and a discharge outlet 14 is connected to the bottom. A cutting mechanism 2 is located on the right side of the feed inlet 12. The cutting mechanism 2 includes a horizontally fixed first cylinder 21, a drive plate 23 driven by the first cylinder 21 to advance towards the feed inlet 12, a mounting bracket 26 fixed on the drive plate 23, and a cutting blade mounted on the end of the mounting bracket 26. The cutting blade consists of a cutting motor 27 and a cutting wheel 28. The cutting motor 27 is fixedly mounted on the end of the mounting bracket 26, and the cutting wheel 28 is connected to the output end of the cutting motor 27. A second baffle 122 is located on the side wall of the feed inlet 12 near the cutting mechanism 2. The second baffle 122 has a second clearance opening 1221 for the cutting blade to advance. When in use, when there is difficult-to-crush construction waste on the crushing roller 13, the first cylinder 21 can drive the cutting blade to advance and assist in cutting and crushing the construction waste, thereby improving the crushing efficiency.

[0018] In another embodiment, the aforementioned mounting bracket 26 is hinged to the drive plate 23. Specifically, a mounting base 25 is fixedly mounted on the drive plate 23, and the mounting bracket 26 is hinged to the mounting base 25. A second cylinder 24 is fixedly mounted on the side of the drive plate 23 away from the mounting bracket 26. The output end of the second cylinder 24 passes through the drive plate 23 and is connected to a push-pull member 241. A connecting rod 242 is hinged between the push-pull member 241 and the mounting bracket 26. Therefore, the tilt of the mounting bracket 26 can be controlled by the extension and retraction of the second cylinder 24, thereby realizing the height adjustment of the cutting tool. This allows for convenient adjustment of the cutting tool's height and cutting depth according to the size of the construction waste. Furthermore, before the cutting tool retracts, the second cylinder 24 can be used to adjust the cutting tool to a vertical position before retracting it. This avoids the problem of the cutting tool being difficult to retract completely in a horizontal position, while minimizing the second clearance opening 1221.

[0019] Based on the above embodiment, a connecting plate 123 is fixedly connected to the outer side of the second baffle 122, and a cylinder bracket 125 is fixedly connected to the connecting plate 123. The first cylinder 21 is horizontally arranged and fixedly installed on the cylinder bracket 125. A limiting seat 124 is also fixedly provided on the connecting plate 123. A connecting rod 22 is connected to the output end of the first cylinder 21. The connecting rod 22 passes through the limiting seat 124 and slides with the limiting seat 124. The end of the connecting rod 22 away from the first cylinder 21 is connected to the drive plate 23. According to this arrangement, the horizontality and stability of the connecting rod 22 when it is pushed forward and pulled out can be guaranteed.

[0020] Based on the above embodiment, a push plate 4 is provided at intervals on the side of the mounting base 25 facing the feed inlet 12. A telescopic rod 41 is connected between the push plate 4 and the mounting base 25. A return spring 42 is sleeved on the telescopic rod 41. A micro switch 43 is provided on the side of the mounting base 25 facing the push plate 4. The micro switch 43 is connected to a microcontroller. The microcontroller is connected to the first cylinder 21 and the second cylinder 24. The side wall of the feed inlet 12 away from the cutting mechanism 2 is a first baffle 121. A first clearance opening 1211 for the cutting wheel 28 to advance is provided on the first baffle 121. A laser sensor 3 is also fixedly connected to the top of the first baffle 121 by an L-shaped bracket 31. The laser sensor 3 is set downwards and is connected to the microcontroller. When the first cylinder 21 pushes the cutting blade, the cutting blade is in a vertical position. The first cylinder 21 drives the drive plate 23 and the mounting base 25 to move towards the feed port 12. The push plate 4 pushes the construction waste to the other side of the feed port 12 before the mounting base 25 and presses against the first baffle 121. Then, it squeezes the reset spring 42 and the telescopic rod 41 until the micro switch 43 is triggered. At this time, the laser sensor 3 can monitor the height of the construction waste. The microcontroller turns on the cutting motor 27 and the second cylinder 24 according to the trigger signal of the micro switch 43. At the same time, it controls the extension and retraction of the second cylinder 24 according to the height data monitored by the laser sensor 3, thereby realizing the precise cutting and control of the construction waste by the cutting wheel 28.
