Rotary harrow drilling tool for deep ploughing and deep loosening device

Abstract

The invention provides a rotary harrow drilling tool for a deep ploughing and deep loosening device. The rotary harrow drilling tool comprises a main drilling rod, a driving rake blade, a helical blade, digging teeth and a soil cutting blade; the driving rake blade is arranged at the top of the main drilling rod; the helical blade is arranged at the lower part of the main drilling rod; the diggingteeth are arranged at the outer edge of the helical blade and every two adjacent digging teeth are arranged at a specific interval; the soil cutting blade is connected with the tail end of the helical blade; the width of the helical blade is gradually reduced along the direction from the top to the bottom of the main drilling rod; and each digging tooth is of a conical body structure. The rotaryharrow drilling tool provided by the invention has the advantages of simple structure, small soil digging resistance, long service life and reduced damage to a soil layer.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a rotary harrow drilling tool for deep plowing and subsoiling equipment. Background technique [0002] Cultivated land is the basic requirement of agricultural production, and it can provide a growth environment for crops during the development process of crops. Therefore, in agricultural production, the use of mechanized cultivated land is an important guarantee for promoting the good growth of crops. The quality of land structure directly affects the yield and quality of crops. Mechanized deep plowing and subsoiling technology solves the structural problems of the land. Deep plowing and subsoiling can loosen the soil layer without overturning the soil layer. In the process of modern agricultural land cultivation, deep plowing and subsoiling equipment are widely used. The deep plowing and subsoiling equipment in the prior art mostly has a blade-type d...

AI Technical Summary

Problems solved by technology

The deep plowing and subsoiling equipment in the prior art mostly has a blade-type design for the soil entry structure, which lacks an auxiliary structure for entry into the soil. During the process of plowing, the resistance to entry into the soil is large; and the existing blades are wide. When the cultivated soil is clay, the wide blades It will bring the lower layer of soil to the upper layer during the rotation process, flipping and destroying the soil layer, which is not conducive to crop growth; when the cultivated soil is hard soil, the lower surface of the blade is easily worn when cutting and rubbing the soil, and the service life is short
