Soil-feeding and film-pressing device of rotary-tillage, ridging, fertilizing and film-mulching machine

Abstract

The invention discloses a soil-feeding and film-pressing device of a rotary-tillage, ridging, fertilizing and film-mulching machine. The soil-feeding and film-pressing device comprises a rotary-tillage, ridging and fertilizing machine, wherein a film-mulching device is arranged behind the rotary-tillage, ridging and fertilizing machine, a soil-feeding cylinder is installed in the middle of the rear end of the rotary-tillage, ridging and fertilizing machine and is bent towards the ground on the outer side of a transmission chain wheel shaft, a transmission chain which is driven by a transmission chain wheel and the transmission chain wheel shaft is arranged inside the soil-feeding cylinder, rubber plates are fixed on the transmission chain, and the transmission chain wheel is matched with an intermediate chain wheel on an intermediate bearing block through a chain and is in transmission connection with a power output chain wheel through a power output chain. The soil-feeding and film-pressing device has the advantages that when the rotary-tillage, ridging and fertilizing machine advances for ridging, a certain amount of soil is taken by the soil-feeding cylinder from the middle of a broad ridge at the back and conveyed by the chain and the rubber plates on the chain to the position of the rear film-mulching device to press a film, so that the problem that soil laying and film mulching can not be conducted in the middle of large ridge broad films can be solved, and the problem that the operation can only be completed through manual operation instead of machines previously is solved. The production efficiency is greatly improved, and the operation cost is reduced. The agricultural requirement for soil-feeding and film-pressing in the middle of the large ridge broad films is met.

Description

technical field [0001] The invention belongs to a rotary tillage ridge-forming film-covering machine in agricultural machinery, and specifically relates to a soil-pressing film-pressing device on a rotary tillage ridge-forming fertilization film-covering machine. Background technique [0002] At present, due to the continuous innovation of farming technology, in some fields of agricultural crops, such as yellow tobacco, vegetables, fruit trees and other technical fields, the wide-ridge cultivation technology in the large-ridge wide-film technology has been well applied. However, there is a problem that plagues people in the promotion of wide-ridge technology, that is, the intermediate lamination of wide-ridge lamination cannot be realized, and manual soil lamination has always been used, which is not only inefficient, but also unreliable. And if do not carry out intermediate film pressing, it will cause the covering film to be overturned by the wind and cannot protect the gr...
