Subsoiler of planetary driving type

Abstract

The invention relates to a subsoiler of planetary driving type, mainly and structurally comprising a gearbox, two cruciform planet carriers, a central shaft, a sun wheel, a middle wheel, planet wheels, cutter shafts and coulters. The centers of the cruciform planet carriers are respectively fixed at both ends of the central shaft, the sun wheel is fixedly mounted on the central shaft, the cutter shafts are mounted in parallel among eight end points of the two cruciform planet carriers, the planet wheels are respectively and fixedly mounted on the cutter shafts, and the coulters are vertically distributed on the cutter shafts which are also driven by the planet wheels to autorotate while revolving around the sun wheel along with the cruciform planet carriers so that the coulters vertically distributed on the cutter shafts are constantly in vertical states, and the coulters on the cutter shafts can vertically exit after vertically cutting, pitting and subsoiling soil by turns. The invention has the advantages of simple and reasonable structure, low production cost, small traction resistance and pitting resistance, low driving power, obvious energy-saving effect, convenient adjustment of loosening depth and density, and the like, is a pitting-type subsoiler with good subsoiling effect and fills the gap of pitting-type subsoiling equipment.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to an agricultural machine for deeply loosening the soil. It belongs to the field of agricultural machinery. Background technique [0002] The cultivated land soil at the bottom of the plow layer is over-compacted due to the trampling of humans and animals and the rolling of machines, especially due to the plowing of the plow year after year, a hard plow bottom layer is formed at the bottom of the plow layer. The depth of the bottom layer of the plow in the field cultivated by animal power is generally 12-15cm, and the thickness is 8-10cm; After the soil is compacted, the soil voids become smaller, and the water permeability and air permeability of the soil decrease, resulting in soil erosion. And because the soil cannot supply oxygen enough and remove CO 2 、H 2 S, CH 4 Such harmful gases hinder the normal metabolism and other physiological functions of crop roots, and also lead to th...

AI Technical Summary

Problems solved by technology

The all-round subsoiler is prone to straw congestion, and the upper subsoiling range is large, while the bottom subsoiling range is small, which cannot effectively solve the problem of water infiltration

The chisel type subsoiler has a small subsoiling range at the bottom and a narrow operating range

In particular, the two types of subsoilers press the subsoiler into the soil (passively buried) under the drive of the tractor, and then the tractor pulls it forward to loosen the soil. Difficult, low transmission efficiency, high energy consumption
