Mulching film laying device suitable for agricultural mechanized cultivation

Abstract

The invention provides a mulching film laying device suitable for agricultural mechanized cultivation, and relates to the technical field of agricultural machinery. The mulching film laying device suitable for agricultural mechanized cultivation comprises a conversion frame and two fixed connecting components, wherein each of the left end and the right end of the conversion frame is of a crisscross structure, and a hollow metal pipe is arranged in the conversion frame in a surrounding mode; the left end and the right end of the conversion frame are respectively connected with two side connecting rods; the left end of the conversion frame is connected with a driving drive plate through a driven grooved wheel; in addition, the right end of the conversion frame is connected with an elastic pin through a pin nose; the two fixed connecting components are connected with the conversion frame through the side connecting rods; and the tops of press rods are connected with the fixed connecting components. After a mulching film at the bottom end of the conversion frame is used up, the conversion frame can be rotationally adjusted, so that another roll of mulching film rotates to the bottom end of the conversion frame for performing the mulching film laying operation, the mulching film replacement time is shortened, and the mulching film laying efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and more specifically relates to a film laying device suitable for agricultural mechanized cultivation. Background technique [0002] Film mulching is a kind of agricultural cultivation technology, which has the functions of increasing temperature, water retention, fertilizer retention, improving soil physical and chemical properties, increasing soil fertility, inhibiting weed growth, and reducing diseases. It also has the function of reducing humidity in the case of continuous rainfall. Thereby promoting plant growth and development, early flowering and fruiting, increasing production and reducing labor costs. [0003] The film laying device of agricultural mechanized cultivation can refer to patent CN108849145B, which mainly includes a bottom plate, a wheel, a rotating shaft, a film roll, a plastic film, an N-shaped frame, a first fixing plate, an elastic member, a top plate, etc...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a film laying device suitable for agricultural mechanized cultivation, to solve the problem that the existing similar film laying devices for agricultural cultivation can only carry a single roll of film for laying operations. After completion, it takes a long time to replace manually, and it is impossible to directly replace the mulch tubes using the outer wall, which will easily affect the efficiency of mulch laying
