United pneumatic deep-scarification soil-preparation fertilizer applying machine

Abstract

The invention relates to a combined pneumatic subsoiling soil preparation and fertilization machine, which belongs to the field of agricultural machinery; the combined pneumatic subsoiling and soil preparation and fertilization machine comprises a front subsoiling device, a rear subsoiling device, an air generating device, a gas fertilization device, and an air-gas connection device , broken soil leveling device, depth adjustment device, traction device and frame; the front subsoiling device is set on the front lower side of the frame, the rear subsoiling device is set on the rear lower side of the frame, and the air generating device is set on the frame On the front upper side, the gas fertilization device is arranged on the middle and upper side of the frame, the air-gas connection device is fixedly connected to the rear beam 3 of the frame, the broken soil leveling device is arranged at the rear of the frame, and the depth adjustment device is arranged on the front two sides of the frame. On the side, the traction device is set at the front of the frame to connect with the connecting device of the tractor; the present invention adopts a combined pneumatic subsoiling soil preparation and fertilization machine, layered subsoiling, soil preparation and fertilization can be carried out independently or simultaneously, thereby effectively reducing the The traction resistance suffered by the machine reduces energy consumption and loosens the soil.

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
