Description

Technical Field

[0001] This utility model relates to the field of solid waste screening technology, specifically a solid waste screening device with a crushing mechanism. Background Technology

[0002] Solid waste refers to solid, semi-solid, and gaseous items and substances placed in containers that are generated during production, daily life, and other activities and have lost their original utilization value or have been discarded or abandoned, as well as items and substances that are included in the management of solid waste as stipulated by laws and administrative regulations.

[0003] A screening device for solid waste treatment, disclosed in CN115634744B, uses a screening barrel to screen the treated solid waste. The barrel-shaped structure reduces the embedding of debris. During the screening process, a third motor drives the screening barrel to reciprocate back and forth, which increases the screening effect of solid waste and prevents residues from adhering to the inner wall of the screening barrel, thus avoiding time-consuming cleaning.

[0004] The solid waste treatment screening device uses a screening barrel to screen the treated solid waste. However, while the device screens the solid waste through the screening barrel, the crushed solid waste cannot completely fall into the screening barrel and can directly fall into the collection box. Therefore, it cannot effectively screen the crushed solid waste and needs to be improved. Utility Model Content

[0028] Furthermore, the outer side of the spring 38 is fixedly connected to the inner side of the slide plate 301, and the inner side of the spring 38 is fixedly connected to the outer side of the crushing box 2. Through the elastic force of the spring 38, when the rack 31 is not driven by the half gear 32, the rack 31 and the screening box 37 can return to their original positions through the elastic force of the spring 38.

[0029] Furthermore, the front and rear sides of the crushing box 2 are provided with sliding grooves corresponding to the movement trajectory of the rack 31, and the rack 31 is slidably connected inside the sliding grooves. Through the sliding grooves, the rack 31 can slide inside the crushing box 2, so that when the rack 31 moves, it can drive the screening box 37 to move, so that the screening box 37 can screen the crushed solid waste.
