Description

Technical Field

[0001] This utility model relates to the technical field of waste treatment equipment, specifically a crushing mechanism for solid waste treatment equipment. Background Technology

[0002] In the process of solid waste treatment, crushers are often used to crush solid waste. Among them, the twin-shaft shear crusher is the most commonly used equipment for treating common solid waste. It has a good crushing effect on domestic waste, hazardous waste, medical waste, industrial waste, etc., and is widely used in various solid waste treatment projects at home and abroad.

[0003] In actual use, when crushing objects such as plastic bottles and buckets, the crushing blades may only be able to glide over the surface of the object being crushed. As a result, the object will rotate for a while before being bitten by the crushing blades, which leads to inefficient crushing of the object. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a crushing mechanism for solid waste treatment equipment.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] As a preferred embodiment of this utility model, the fixed sleeve is fixedly connected to the anti-splash cover, and a locking bolt for locking the adjusting rod is screwed onto the fixed sleeve.

[0009] As a preferred embodiment of this utility model, the driver includes two electric telescopic rods arranged in an inclined manner, an upper mounting head installed at the top of the piston rod of the electric telescopic rod, and a lower mounting head installed at the bottom of the electric telescopic rod. Both the upper and lower mounting heads are hinged with mounting brackets. The mounting bracket connected to the upper mounting head is installed at the bottom of the splash guard, and the mounting bracket connected to the lower mounting head is installed on one side of the housing.

[0010] As a preferred technical solution of this utility model, the dual-shaft crushing assembly includes two crushing blade shafts that pass through the housing. Bearings are provided at the connection between the two crushing blade shafts and the housing. Multiple crushing blades are sleeved and fixed on the outer wall of the crushing blade shafts.

[0011] As a preferred embodiment of this utility model, the drive assembly includes a drive motor and two drive gears sleeved and fixed to one end of the crusher shaft. The two drive gears mesh with each other, and a transmission head is fixed to the output shaft of the drive motor.

[0012] As a preferred technical solution of this utility model, a protective shell is provided at one end of the box body, the drive gear is located inside the protective shell, and one end of one of the crushing blade shafts passes through the protective shell and is connected to the transmission head through a transmission belt. A bushing is provided at the connection between the crushing blade shaft and the protective shell.

[0013] The beneficial effects of this utility model are:

[0014] 1. The crushing mechanism of this solid waste treatment equipment retracts via an electric telescopic piston rod, causing the anti-splash cover to move along with the auxiliary bite plate. The moving auxiliary bite plate pushes the solid waste, thereby accelerating the speed at which the crushing blades bite into the solid waste, thus improving the crushing efficiency. In addition, the anti-splash cover can cover the feed hopper, effectively preventing the crushed waste from flying out of the feed hopper, which helps maintain environmental cleanliness.

[0015] 2. The crushing mechanism of this solid waste treatment equipment allows the connecting bracket to rotate around the adjusting rod by loosening the adjusting bolt, thereby adjusting the angle of the auxiliary biting inclined plate. This facilitates the auxiliary dual-shaft crushing component to bite the object being crushed. By loosening the locking bolt, the adjusting rod can slide within the fixed sleeve, thereby changing the height of the auxiliary biting inclined plate, thus enabling it to be used for crushing objects of different volumes.
