United pneumatic deep-scarification soil-preparation fertilizer applying machine

Abstract

The invention relates to a united pneumatic deep-scarification soil-preparation fertilizer applying machine, and belongs to the field of agricultural machinery. The united pneumatic deep-scarification soil-preparation fertilizer applying machine comprises a front-part deep scarification device, a rear-part deep scarification device, an air generating device, gas fertilizer applying devices, gas-gas connecting devices, a soil crushing and soil leveling device, a depth adjusting device, a traction device and a machine frame, wherein the front-part deep scarification device is arranged on the front lower side of the machine frame; the rear-part deep scarification device is arranged on the rear lower side of the machine frame; the air generating device is arranged on the front upper side of the machine frame; the gas fertilizer applying devices are arranged on the middle and upper side of the machine frame; the gas-gas connecting devices are fixedly connected to a rear beam 3 of the machine frame; the soil crushing and soil leveling device is arranged behind the machine frame; the depth adjusting device is arranged on two sides of the front part of the machine frame; and the traction device is arranged at the front part of the machine frame and is connected with a connecting device of a tractor. According to the united pneumatic deep-scarification soil-preparation fertilizer applying machine disclosed by the invention, layered deep scarification, soil preparation and fertilizer application not only can be separately performed but also can be performed at the same time, so that traction resistance on machinery can be effectively reduced, the energy consumption is reduced, and soil is scarification.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a combined pneumatic subsoiler and soil preparation fertilizer applicator. Background technique [0002] Soil subsoiling refers to the use of a subsoiler to break the plow layer of the soil, loosen the soil and increase the thickness of the plowing layer; soil subsoiling technology can improve the physical and chemical properties of the soil, improve the three-phase ratio of soil solid, liquid and gas substances, and strengthen soil microorganisms The ability to survive and reproduce, accelerate the mineralization and weathering of organic matter, improve soil structure, enhance soil adsorption capacity, and improve soil fertility; soil deep loosening technology can also improve the lodging resistance of crops, deep loosening operations break the bottom of the plow and form rat holes , which increases the depth of the plow layer and the water permeability of the soil, blocks...

AI Technical Summary

Problems solved by technology

[0003] The cultivated land has been prepared by plowing or rotary tillage for a long time. On the one hand, it leads to the thinning of the plow layer, soil compaction, and the increase of soil specific resistance year by year, and the required farming power is also increasing; Plowing to the surface will destroy the original soil plow layer structure, which is not conducive to crop growth
