AI Technical Summary

Technical Problem

Existing spray film equipment has difficulty fully mixing liquid mulch film raw materials, leading to the separation or precipitation of chemical substances, which affects the strength and service life of the mulch film.

Method used

The mixing section is designed, including a stirring component and a turbulence component. The motor drives the rotating shaft to move the spiral stirring blades and the protrusions on the arc-shaped seat to achieve full mixing of the liquid mulch film raw materials. The spraying section ensures uniform spraying and the formation of a consistent protective film through the moving component and the driving component.

Benefits of technology

This process ensures thorough mixing of the liquid mulch film raw materials, preventing sedimentation and stratification, guaranteeing stable quality of the sprayed mulch film, and improving spraying efficiency and uniformity.

Abstract

The utility model discloses a film spraying device for an agricultural degradable mulching film, and relates to the technical field of film spraying devices. The liquid mulching film mixing vehicle comprises a vehicle body, a liquid storage barrel is mounted at the top of the vehicle body, and the liquid mulching film mixing vehicle further comprises a mixing part, a spraying part and a spraying part, the mixing part is mounted in the liquid storage barrel, and the mixing part is used for mixing liquid mulching film raw materials in the liquid storage barrel; and a film spraying part. Through the mixing part, when liquid mulching film raw materials in the liquid storage barrel need to be mixed, the motor is firstly started, the motor drives the rotating shaft to rotate, and the rotating shaft drives the spiral stirring blades to rotate to mix and stir the liquid mulching film raw materials in the liquid storage barrel when rotating; when the liquid mulching film raw materials are sprayed out, the liquid mulching film raw materials can impact the arc-shaped seats and the convex blocks to be disturbed, and the flowing path of the liquid mulching film raw materials is changed, so that the liquid mulching film raw materials are fully and uniformly mixed, precipitation or layering of the liquid mulching film raw materials is avoided, and stable quality of sprayed mulching films is ensured.
