Mulch picker

Abstract

The invention relates to an agricultural machine, in particular to a mulch picker, characterized in that a U-shaped lift shovel (1) is arranged below the front of a frame (3), vertical blades are arranged on two sides of the U-shaped lift shovel (1), a transverse blade is arranged in the middle, the vertical blades are in arc transition with the transverse blade, an included angle between the upper surface of the transverse blade and the horizontal plane is a lift angle that is adjustable, a vibrating shaker grid (12) is hinged to the rear edge of the U-shaped lift shovel (1), a mulch residue and stubble lift chain (7) is arranged below the vibrating shaker grid (12) to perform secondary soil removal, and mulch residue and stubbles are delivered into a mulch collection box (8) via elliptical row-type conveying rollers to perform baling and bundling. The mulch picker has the advantages that the mulch picker has various modes, is widely applicable and is capable of picking surface mulch residue and in-soil mulch residue, the mulch picker is simple in structure and high in picking rate, various operations can be finished at a time, the adverse influence of the mulch residue upon soil structure and crop growth and development is decreased, unit production level of crops is increased, ecological environment is protected, and farmers' income is increased.

Description

technical field [0001] The invention relates to an agricultural machine, namely a mulch picking machine. Background technique [0002] Plastic film mulching is a cultivation technology that improves crop yield and economic benefits. While it brings us the joy of a good harvest, it also leaves us with endless troubles - white pollution. The plastic film is a high-molecular hydrocarbon. Refractory to degradation. Residues in the soil will form many isolation layers, destroy the capillary system of the soil, weaken the permeability of the soil, and destroy the soil structure. When the seeds are sown on the residual film, there will be dry buds and bud drop. Because the residual film isolates the root system and cannot be stuck in the soil, the plants will soon wither, and there will be a lack of seedlings and broken bars, resulting in reduced production. Therefore, it is imperative to recycle the residual film. At present, the structural forms of domestic mulch pickers mainl...

AI Technical Summary

Problems solved by technology

[0003] 1. Telescopic rod-toothed pick-up roller, this kind of film collection mechanism works reliably, and the residual film collection rate is also high, but the structure of the mechanism is complicated, the cost is high, and the plastic film combined with stubble is difficult to recycle

[0004] 2. The shovel-type stubble-recovering film structure, while the stubble is being scooped up, the residual film is scooped up and sent to the squirrel-cage rotating drum through the conveyor belt for soil stubble separation. The structure is simple, the work is reliable, and the collection rate is high. The depth of stubble is shallow, and there are certain requirements on the performance of the soil. The soil lifting shovel is seriously congested, and the drum film is serious.

[0005] 3. The gear-tooth film harvesting structure, which adopts the film harvesting parts of the film harvesting machine at the seedling stage, rotates the film by the friction between the film harvesting wheel and the ground, the structure is simple, the residual film is relatively clean, and it is easy to remove Recycling and utilization, there are many bottleneck problems in the film harvesting machine at the seedling stage, such as easy damage to seedlings, unstable film collection rate, especially the low collection rate of severely damaged residual film

[0006] The above-mentioned mulch picker has a single function and a narrow scope of application

And only the residual film on the surface is picked up, but it is difficult to pick up the remaining film fragments in the soil
