Description

Technical Field

[0001] The utility model relates to the technical field of crushing devices, in particular to a raw material crushing device for producing agricultural mulch films. Background Art

[0002] Agricultural mulch film is a general term for plastic films used in agricultural production. It plays a vital role in maintaining moisture and heat during the sowing season. With the advancement of science and technology, the requirements for agricultural films are becoming increasingly stringent, and various new types of films are constantly emerging. During the processing of mulch film, the raw materials need to be crushed. Existing crushing equipment generally uses a single-stage crushing process. If the crushing fineness is not enough, it needs to be crushed again. This not only reduces the efficiency of mulch film production, but also increases production costs.

[0003] An existing device for pulverizing raw materials used in the production of fully biodegradable agricultural mulch film (Announcement No.: CN217016882U) has at least the following drawbacks: The device allows the raw materials for the production of fully biodegradable mulch film to be added to the interior of the housing through a feed trough. The first and second blades cooperate to fully pulverize the fully biodegradable mulch film. The pulverized raw materials are then discharged from the interior of the housing through a discharge hole. A raw material collection device is placed inside the collection bin, and the pulverized raw materials fall directly into the raw material collection device, completing the collection of the raw materials. This pulverizing device has a simple structure, is easy to operate, has a good pulverizing effect, and facilitates the collection of raw materials, effectively improving production efficiency and reducing production costs. However, only the first blade rotates, while the second blade is fixed, resulting in low cutting efficiency. Furthermore, the device's structural design is difficult to install and disassemble, making it difficult to repair and replace the blades. Utility Model Content
