High-speed stubble shifting single body capable of automatically regulating and controlling penetrating depth

Abstract

The invention discloses a high-speed stubble shifting single body capable of automatically regulating and controlling the depth of soil, and belongs to the technical field of agricultural machinery, and the high-speed stubble shifting single body is composed of a connecting rod profiling mechanism, a depth limiting wheel assembly, a stubble shifting wheel assembly, a pneumatic system, an electric control system and a rack. The technical problem that in the prior art, when operation is carried out in less and no-tillage fields, the soil penetrating depth stability and the profiling sensitivity of the stubble shifting wheel are easily influenced by the operation environment and speed can be solved, meanwhile, the phenomenon that the straw cleaning and stubble shifting effects are inconsistent due to the fact that the soil penetrating depth of the stubble shifting wheel is unstable can be avoided, and the stubble shifting single body is separated from the seeding single body. Adverse effects on seeding operation are reduced, and high-quality seedbed conditions can be provided for crop seeding and fertilization operation; the straw cleaning and stubble shifting device is simple in structure, easy to regulate and control, suitable for straw cleaning and stubble shifting operation of straw covered land and uneven land parcels, and good in straw cleaning effect.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a high-speed stubble picking unit with automatic control of the depth of entry into the soil. Background technique [0002] Seed bed cleaning is the main technical difficulty in low-tillage and no-tillage seeding. The stubble picking mechanism can pick up and turn over straw and weeds, clean the seedbed, increase the ground temperature, increase the passability of the no-tillage planter, reduce machine blockage, and improve the quality of sowing . After the crops are harvested, the crop straw, root stubble and weeds remain on the ground. The difference in straw coverage before and after the operation of clearing the seed bed is the rate of clearing the straw in the seed bed. The clearing rate of the seed bed of the stubble mechanism directly affects The operation quality of the tiller and seeder and the consistency of seed germination. In the actual o...

Problems solved by technology

Although the active profiling stubble picking device can adjust the working width in real time on undulating ground, the pressure sensor cannot accurately reflect the actual working width of the stubble picking wheel when the soil firmness in the field changes greatly.

In addition, when performing high-speed stubble picking operations in the field, the response speed of the active profiling mechanism using the electric push rod is slow, the profiling sensitivity is insufficient, the device is vulnerable to impact, and the consistency of the stubble picking effect cannot be guaranteed
