Description

Technical Field

[0001] The utility model relates to the technical field of construction waste treatment, in particular to an all-purpose crushing device for construction waste treatment. Background Art

[0002] At present, the crushing of construction waste refers to the process of crushing waste generated by construction, renovation, demolition, etc. of construction projects. These wastes include concrete, bricks, stones, sand and other materials. The purpose of crushing is to convert these wastes into smaller particles or powders for further processing and utilization. In the process of crushing construction waste, crushers or grinders are usually used to crush the waste into the required particle size through impact, rolling or shearing. The crushed construction waste can be used to manufacture recycled building materials, landfill, covering materials, etc., to achieve the recycling of resources, and also help reduce the exploitation of natural resources and environmental pollution.

[0003] In the prior art, the authorization announcement number is: CN214974307U, a crushing device for treating construction waste, which includes a shell, a motor box is fixedly connected to one side of the shell, a fixed column is fixedly connected to the inner wall of the motor box, and a first motor is fixedly connected to one end of the fixed column. The first motor and the second motor rotate in opposite directions to ensure the close cooperation of the first roller and the second roller. This cooperation mode can fully squeeze and crush construction waste such as stone during crushing. In this way, the fragments produced by the crushing of construction waste are more uniform and delicate, which greatly improves the crushing effect. This design solves the problem of low efficiency of the current general crushing means for treating construction waste. After using this patent, people do not need to rework the construction waste for a second time, which greatly improves the work efficiency of the staff;

[0004] However, when the patent is crushing, dust will be raised, which will affect the surrounding environment and the health of workers. In addition, when the construction waste is crushed, the patent will vibrate, and the ground of the construction site is uneven, so the patent is easy to tilt and overturn.

[0005] In the prior art, the authorization announcement number is: CN212189272U, a construction waste treatment device, which includes a crushing barrel, a feeding hopper and a flap, etc. The feeding hopper is fixedly installed on the upper part of the crushing barrel to facilitate the input of waste, and the flap is movably installed at the bottom of the feeding hopper, which can cover the crushing barrel by turning over to prevent the dust and gravel inside from splashing. The crushing barrel is fixedly installed with a squeezing roller 1 and a squeezing roller 2, and these two groups of squeezing rollers are rotatably connected through a gear set 1 and a gear set 2. This design can fully crush and roll the waste in the crushing barrel, greatly improving the treatment efficiency. The patent is simple to operate and fully functional, and is an ideal choice for treating construction waste. Whether it is a large construction site or a small construction project, it can get effective waste treatment;

[0006] However, this patent also fails to effectively handle the dust generated during crushing, which will cause dust to fly. Utility Model Content
