Scarifier for modern agricultural cultivation

Abstract

The invention discloses a scarifier for modern agricultural cultivation. The scarifier structurally comprises a moving vehicle, a driving box, a pushing handle, driving wheels, a scarifier cutter, a scarifying rod and supporting feet, wherein the driving box is fixedly mounted in the middle of the upper surface of the moving vehicle, and the right end surface of the moving vehicle is welded to the lower end of the pushing handle. Through stretching out and drawing back of a spring rod, an outer cutting edge stretches out and draws back on the outer side of a rotary cutter body, the effect of loosening the sandy soil is improved, rotation descending is conducted through a gravity ball, a push piece and a sharp cutter stretch out of the outer side of a contact rotating piece, the sandy soil in the contact rotating piece is pushed out, and it is ensured that the contact rotating piece can normally rotate and move in the sandy soil; and when the contact rotating piece rotates, the outer side surface makes contact with a long plate and a scraping strip, a hinge shaft slides in a hinge plate, then through extrusion of a compression spring, it is ensured that a linkage rod keeps a certain extrusion force, and therefore, clay on a scraping plate and the contact rotating piece is normally scraped away, and meanwhile, the contact rotating piece can normally rotate to loosen soil.

Description

technical field [0001] The invention relates to the technical field of modern agriculture, and more specifically, relates to a scarifier for modern agricultural cultivation. Background technique [0002] Small scarifiers are based on hills. In mountainous areas, the land is small, the height difference is large, and it is designed for non-organic farming roads. It adopts front-wheel drive, which makes the operation easier. The sandy soil has weak drought resistance and is prone to water leakage. It is necessary to use a small scarifier to loosen the sandy soil. However, the sandy soil is the soil with a high sand content in the soil particle composition, and a certain amount of clay is mixed. When the small ripper loosens the sandy soil, the ripper knife of the small ripper rotates, Contact with the sand to disperse the sand. During the contact process, the distance between the scarifier knife and the sand grains is consistent, and the content of sand grains in some positio...

Problems solved by technology

In mountainous areas, the land is small, the height difference is large, and it is designed for non-organic farming roads. It adopts front-wheel drive, which makes the operation easier. The sandy soil has weak drought resistance and is prone to water leakage. It is necessary to use a small scarifier to loosen the sandy soil. However, the sandy soil is the soil with a high sand content in the soil particle composition, and a certain amount of clay is mixed. When the small ripper loosens the sandy soil, the ripper knife of the small ripper rotates, Contact with the sand to disperse the sand. During the contact process, the distance between the scarifier knife and the sand grains is consistent, and the content of sand grains in some positions is relatively high, resulting in the gap between the scarifier knife and the sand grains. At the same time, the clay is easy to stick to the surface of the scarifier knife, causing the scarifier knife to get stuck inside the sand when loosening the soil, making it difficult to rotate and feed the knife
