No-tillage double-furrow full film-covering combined operation machine

Abstract

The invention relates to the technical field of agricultural machinery, in particular to a ploughing-free dual-furrow full-film-mulch earthing combined machine, which comprises a frame, a rotary cultivator, a solid conveying mechanism, a reshaping, compressing and deep limiting mechanism, a soil distributing mechanism and a soil belt compressing mechanism, wherein the rotary cultivator is arranged below the front side of the frame; the soil conveying mechanism is arranged on the middle part of the frame; the reshaping, compressing and deep limiting mechanism is arranged on the lower middle side of the frame; the soil distributing mechanism is arranged on the back upper side of the frame; the soil belt compressing mechanism comprises a soil belt compressing wheel, a profiled arm and a profiled arm compressing pull spring; one end of the profiled arm is connected with the soil belt compressing wheel; the other end of the profiled belt is connected with a side connecting frame; and the profiled arm compressing pull spring is formed between the profiled arm and the side connecting frame. The combined machine provided by the invention has multiple functions of rotary ploughing, grooving, reshaping, film mulching, earthing, compressing, perforating and the like, and has the advantages of reasonable structural configuration, complete functions, high suitability and high working reliability.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a no-tillage double-furrow full-film-covering combined operation machine. Background technique [0002] At present, there have been many types of double-furrow full-laying film-covering machines in China. Among them, the soil-feeding and film-pressing mechanism and the ditching soil-taking mechanism are not mature enough. Changes in natural conditions such as grass have caused problems in terms of reliability and adaptability of machines. The soil between the conveyor belt and the pulley of the ditch soil collection mechanism is very easy to get clay, so that the diameter of the pulley continues to increase, and the conveyor belt will eventually be stretched; the soil at the bottom of the ditch is compacted by the depth-limited shaping and pressing wheel, so that the seeder cannot put the seeds On-demand to the predetermined depth; at the same time, there is no su...
