Description

Technical Field

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

[0002] Construction waste refers to waste concrete, waste bricks and stones, and other waste generated by construction units or individuals during the construction, laying, demolition, and repair of various buildings and structures.

[0003] Traditional construction waste crushing equipment is too bulky to transport to the construction site for practical use. Construction waste needs to be transported to a specific site for crushing, and secondary utilization of construction waste requires re-transportation, which incurs significant transportation costs. During the process of moving construction waste out of the building, the large size of the waste makes it difficult to pack and transport, causing inconvenience. Furthermore, existing small crushing devices have low crushing efficiency and cannot meet the needs of users.

[0004] Therefore, there is a need for a construction waste crushing device that can be easily moved indoors for crushing operations to solve the problems existing in the prior art. Utility Model Content

[0018] 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.

[0019] Please see Figures 1 to 3The present invention provides the following technical solution:

[0020] A construction waste crushing device includes a body 1, with a feed inlet 11 at the top for feeding construction waste into the body 1, and a discharge outlet 12 at the bottom for discharging the crushed construction waste. The device also includes a drive module and a crushing assembly. The crushing assembly is installed inside the body 1 and connected to the drive module. The drive module drives the crushing assembly to crush the construction waste inside the body 1. The drive module is located outside the body 1.

[0021] The crushing assembly includes a crushing module and a baffle module. The crushing module is connected to the drive module, and the baffle module is located on the side of the crushing module and on the inner top wall of the machine body 1. The crushing module rolls and pushes the construction waste, so that the construction waste is pushed between the crushing module and the baffle module. The construction waste can be crushed by the squeezing of the two.

[0022] The crushing module includes a crushing roller 3 and several crushing hammers 32. Several mounting slots 31 are evenly provided on the crushing roller 3. The crushing hammers 32 are installed in the mounting slots 31. The crushing hammers 32 can be disassembled and replaced.

[0023] The crushing roller 3 has a multi-faceted prism structure, and the breaker 32 is installed on the convex part of the crushing roller 3, making the position of the breaker 32 more prominent and improving the crushing effect on construction waste.

[0024] The surface of the crushing roller 3 is uniformly provided with several crushing protrusions 33, and the crushing protrusions 33 are hemispherical in shape. The crushing protrusions 33 can enhance the friction of the crushing roller 3 in squeezing and pushing construction waste, thereby improving the crushing effect of the crushing roller 3 on construction waste.

[0025] The material blocking module includes several material blocking structures, each of which is evenly installed on the top wall of the machine body 1. Each material blocking mechanism includes several adjusting screws 41, a limiting plate 42, a fixed seat 43, and several pressing blocks 44. The fixed seat 43 is fixedly connected to one end of the adjusting screw 41. The adjusting screw 41 is slidably installed in the movable hole 13 on the top wall of the machine body 1. The limiting plate 42 is screwed onto the adjusting screw 41 via threads, and the limiting plate 42 is located at the top of the machine body 1. By adjusting the position of the limiting plate 42 on the adjusting screw 41, the material blocking mechanism can be adjusted. The distance between the fixed seat 43 and the crushing roller 3 is adjusted to control the size of the construction waste crushed by the device. The side of the fixed seat 43 near the crushing roller 3 has a concave structure. Several extrusion blocks 44 are evenly arranged on the inner side of the fixed seat 43. The rows of extrusion blocks 44 at the fixed seat 43 are arranged in a stepped manner. The stepped distribution of the extrusion blocks 44 can make the distance between the crushing roller 3 and the fixed seat 43 gradually decrease along the rolling direction of the crushing roller 3, thereby gradually crushing the construction waste and making the size of the construction waste gradually decrease.

[0026] The drive module includes a drive motor 2, a transmission mechanism 21, and a drive shaft 22. The drive motor 2 and the drive shaft 22 are connected through the transmission mechanism 21. The drive shaft 22 is installed inside the crushing roller 3 and is rotatably installed inside the machine body 1. The drive motor 2 can drive the crushing roller 3 to rotate through the transmission mechanism 21 and the drive shaft 22. The transmission mechanism 21 is one of the following mechanisms capable of transmission: belt and pulley transmission mechanism 21, gear transmission mechanism 21, or chain and sprocket transmission mechanism 21.

[0027] The specific implementation process is as follows:

[0028] This construction waste crushing device is mounted on a movable frame, trolley, or other elevated platform to allow for easy material discharge. The space between the fixed base 43 and the crushing roller 3 is adjusted by regulating the position of the limiting plates 42 at the adjusting screws 41 of each material-blocking mechanism, thereby adjusting the crushing size of the construction waste. When using the device, the drive motor 2 is started. The drive motor 2 drives the crushing roller 3 to rotate via the transmission mechanism 21 and drive shaft 22. Construction waste is fed into the machine body 1 through the feed inlet 11. As the crushing roller 3 rotates, it pushes and compresses the construction waste towards the fixed base 43. The crushing hammer 32, in conjunction with the compression blocks 44 on the fixed base 43, crushes the construction waste. Because the compression blocks 44 on the fixed base 43 are arranged in a stepped pattern, the size of the construction waste gradually decreases. Simultaneously, the crushing hammer 32 continuously hammers the construction waste, crushing it. The crushed construction waste is then discharged from the discharge port 12 at the bottom of the machine body 1.

[0029] This construction waste crushing device can be installed on a movable frame or trolley. Construction waste is fed into the feed inlet 11 at the machine body 1. The crushing roller 3 is driven to roll by the drive module, so that the crushing roller 3 and the crushing hammer work together with the various material blocking mechanisms to crush the construction waste. Under the action of the stepped extrusion blocks 44 of the material blocking mechanism, the construction waste is crushed step by step, so that the construction waste is formed into a smaller size, which is convenient for users to bag and transport, effectively reducing the handling and transportation costs of construction waste.
