Airflow-impact deep-scarification fertilizer distributor

Abstract

The invention relates to an airflow-impact deep-scarification fertilizer distributor which belongs to the field of agricultural machines. The airflow-impact deep-scarification fertilizer distributor comprises a deep scarification device, an air generation device, depth control devices, a fertilization device, a gas-liquid connecting device, a draft gear and a rack, wherein the deep scarification device is disposed on the rear lower side of the rack; the air generation device is disposed on the front upper side of the rack; the depth control devices are disposed on two sides of the front part of the rack; the fertilization device is disposed on the middle upper side of the rack; the gas-liquid connecting device is disposed on the rear upper side of the rack; and the draft gear is disposed on the front part of the rack and connected to a draft gear of a tractor. The airflow-impact deep-scarification fertilizer distributor adopted in the invention is characterized in that separate deep scarification can be implemented, and the deep scarification and fertilization can be implemented simultaneously; instant high-pressure airflows generated by an air compressor can break a plow pan so as to obtain effects of the deep scarification on one side; and on the other side, liquid fertilizers can be changed into instant high-pressure liquid flows, and the liquid flows are impacted into soil via a pipeline on the bottom of a deep scarification shovel, so that the fertilization is carried out.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to an airflow impingement subsoiling fertilizer applicator. Background technique [0002] Soil subsoiling refers to the use of a subsoiler to break the plow layer below the plow layer, loosen the soil and increase the thickness of the plow layer. Soil deep loosening is an important technology of soil cultivation, and it has been paid more and more attention at home and abroad. [0003] 1. Soil deep loosening technology can break the plow bottom layer and deepen the plow layer thickness. The existence of the bottom layer of the plow prevents the roots of the crops from piercing through, but can only curl up and grow above the bottom layer of the plow; the barrier of the bottom layer of the plow prevents precipitation from infiltrating and forms surface runoff, causing serious soil erosion; deep loosening of the soil can break the hard Plow the bottom layer, improve soil permea...

AI Technical Summary

Problems solved by technology

The bottom layer of the plow is thickened and the sheet-like structure of the soil layer is firm, resulting in a decrease in the vertically distributed roots of the crops and an increase in the horizontally distributed roots. The deep mineral nutrients are difficult to use, and the lodging resistance of the crops also decreases.
