Electric-hydraulic control type subsoiler

Abstract

The invention relates to an electric-hydraulic control type subsoiler. The electric-hydraulic control type subsoiler is characterized by comprising a hydraulic rack and a depth sensing hydraulic control cabinet, wherein the hydraulic rack is composed of a front beam, a hydraulic device, an upper pull rod, a rear pull rod, a rear beam, a rear beam fixing plate, a transverse beam, a rear beam winding shaft, a rear beam winding plate and a rear beam fixed plate; a hydraulic subsoiling device is arranged under the transverse beam; and a hydraulic depth limiting device is arranged behind the transverse beam. By adopting the depth sensing hydraulic control cabinet, information of a distance sensor can be received, and hydraulic oil amount in the hydraulic device is controlled; the tilling depth of the subsoiler is accurately adjusted by adjusting the hydraulic oil amounts of the hydraulic devices in the hydraulic rack, the hydraulic subsoiling device and hydraulic depth limiting device. Above all, the invention provides the electric-hydraulic control type subsoiler which guarantees consistent tilling depth, feeds back and adjusts the tilling depth in time, reduces resistance and lowers consumption, reaches good soil loosening effect and is convenient to transport and detach, and parts of the electric-hydraulic control type subsoiler are convenient to replace.

Description

Technical field [0001] The invention relates to an electro-hydraulic controlled subsoiler. Background technique [0002] Long-term use of plowing or rotary tillage methods for land preparation on cultivated land has resulted in thinning of the cultivated layer and soil compaction. The specific resistance of the soil is increasing year by year, and the required farming power is also increasing. The widespread use of large-scale agricultural machinery such as high-horsepower tractors has further aggravated the compaction of the soil, leading to a vicious circle and forming a thick and hard plow layer on the cultivated land. The existence of the plow layer reduces the capacity of the cultivated layer and the soil structure becomes worse, forming a "wave-shaped" soil profile structure; leading to more serious surface runoff and soil erosion, weakening of water storage capacity, and increasingly depleted farmland fertility; reducing soil porosity and limiting soil porosity Plant root...

Problems solved by technology

[0004] At present, the problem existing in the existing soil subsoiling machine is: the traction resistance of the subsoiling machine increases with the increase of the depth of soil subsoiling, which increases the cost of subsoiling and fuel consumption, and the existing in the process of subsoiling Problems such as high working resistance and excessive energy consumption have greatly hindered the promotion of subsoiling technology; at the same time, the existing subsoiling machines have the problem of inconsistent plowing depth, and the plowing depth cannot be adjusted in time.
