Combined subsoiler with earthing function

Abstract

The invention discloses a combined subsoiler with an earthing function. The combined subsoiler comprises a subsoiler handle, an earthing combined body, a subsoiler tip, a left subsoiler handle flitchand a right subsoiler handle flitch; the earthing combined body and the subsoiler tip are fixed to the upper side and the lower side of the lower end of the subsoiler handle respectively through bolts; the upper end of the earthing combined body is clamped to the subsoiler handle; the left subsoiler handle flitch and the right subsoiler handle flitch are fixedly connected to the left side and theright side of the lower end of the subsoiler handle respectively, and the upper end of the subsoiler tip is clamped between the left subsoiler handle flitch and the right subsoiler handle flitch. Theearthing combined body is composed of a soil-lifting subsoiler tip, a soil guiding supporting plate and a soil guiding anti-sticking plate. By means of the combined subsoiler with the earthing function, deep scarification can be achieved, plow pan layers are broken through, the combined subsoiler also has the earthing function, so that straw is uniformly mixed and buried into surface soil, the ground temperature is increased, rot of the straw is accelerated, and diseases and insect pests are reduced; meanwhile, a certain ground straw coverage rate can be guaranteed, and the purposes of reducing wind erosion and water erosion and protecting the soil are achieved. Straw mixing and burying is combined with deep scarification, and the development of the conservation tillage mode of total fieldreturning of straw is promoted.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a compound subsoiling shovel with the function of covering soil. Background technique [0002] As a key technology of conservation tillage, subsoiling can break the bottom layer of the plow, promote deep penetration of the root system, improve soil quality, and create a good soil environment for crop growth. Subsoiling is the basis of conservation tillage, which has the following functions: first, it breaks the plow bottom layer, reduces soil bulk density, increases soil porosity, builds soil reservoirs, absorbs rain and snow, and greatly improves soil water storage capacity; second, Make the soil loose, increase the soil roughness, increase the infiltration of soil precipitation, prevent ground water or surface runoff, and reduce water erosion; third, it is conducive to fertilizing the soil, forming a plow layer structure with both virtual and real, an...

Problems solved by technology

In areas where the temperature is low in winter and spring, the "corn stalk mulching no-tillage planting technology" is adopted, that is, deep loosening in autumn and no-tillage planting in spring. The straw is not easy to rot, affects the increase of ground temperature, it is difficult to guarantee the quality of sowing, and it is easy to breed diseases. Cordyceps and other problems, and because a large amount of straw covers the ground, a large amount of pesticides need to be sprayed to solve the pests and weeds, which affects food security and is not conducive to the development of the full-scale straw returning conservation tillage model
