Triangular arc-shaped shovel handle based chisel-shaped sub-soiling shovel with wings

Abstract

The invention discloses a triangular arc-shaped shovel handle based chisel-shaped sub-soiling shovel with wings. The sub-soiling shovel is characterized in that the sub-soiling shovel includes a triangular arc-shaped shovel handle, a fixing bolt, a chisel-shaped shovel tip, shovel wings and fixing nuts; the chisel-shaped shovel tip and the shovel wings form a sub-soiling shovel body, and the sub-soiling shovel body is installed on a sub-soiling shovel handle through the fixing bolt in a hexagonal flower-shaped countersunk head threaded hole; the cross section of the soil-cutting part of the shovel handle is in a triangle shape, so that the soil-cutting angle is small, and tillage resistance can be reduced; a straight rectangular shovel handle is provided with equidistant installation pin holes, and tillage depths can be adjusted through the relative positions of a connecting plate and the installation pin holes. The purpose for providing the chisel-shaped sub-soiling shovel with wingsis realized, and the chisel-shaped is small in soil-cutting angle and convenient in soil cutting and can reduce tillage resistance can be realized; and therefore, sub-soiling operation requirements for reducing tillage resistance and enhancing surface smoothness can be met.

Description

technical field [0001] The invention relates to a subsoiling shovel, in particular to a winged chisel-shaped subsoiling shovel based on a triangular arc-shaped shovel handle, which belongs to the field of agricultural machinery. Background technique [0002] Subsoiling is one of the core technologies of conservation tillage. Existing studies have shown that shovel shape is one of the main factors affecting soil properties, surface smoothness, and traction resistance after subsoiling. At present, the commonly used subsoiling shovel shapes mainly include chisel shape, arrow shape and wing shape. The chisel-shaped shovel has low subsoiling efficiency and poor soil loosening effect after plowing, and it is difficult to exert the effect of subsoiling on soil water storage and moisture conservation. After plowing with wing-shaped shovel, the surface is uneven, the traction resistance is large, and the cost is high. , There are two kinds of commonly used subsoiling shovel handles,...

Problems solved by technology

The chisel-shaped shovel has low subsoiling efficiency and poor soil loosening effect after plowing, and it is difficult to exert the effect of subsoiling on soil water storage and moisture conservation. After plowing with wing-shaped shovel, the surface is uneven, the traction resistance is large, and the cost is high. , there are two kinds of commonly used subsoiling shovel handles, medium and light, which have a large cutting angle, obvious weed entanglement and soil adhesion, and large tillage resistance.
