A subsoiling shovel based on the principle of dynamic bionics

Abstract

The invention discloses a subsoiler based on a dynamic bionic principle. The subsoiler comprises a subsoiler mounting handle, a limiting device, a bidirectional torsion spring, a subsoiler handle, a subsoiler tip and a pulley, wherein the subsoiler mounting handle and the subsoiler handle are mounted through a bearing, so that the subsoiler handle can be rotated at the bottom of the soil; the pulley is mounted at the rear end of the subsoiler handle, is in contact with the limiting device and is used for supplying a support force along a heading direction and limiting the rotating angle; the bidirectional torsion spring is mounted at the external end of the bearing, so that the rotating resetting of the subsoiler is realized and the dynamic operation effect is achieved; the subsoiler is optimized through bionic curve design, so that the improvement of the soil-breaking property is ensured; the dynamic bionic principle is designed and the moving form of the whole subsoiler is similar to the forms of the animals, such as, earthworm, mole cricket, and the like, in the moving process, so that the dynamic bionic motion is realized.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a subsoiler shovel based on the principle of dynamic bionics. Background technique [0002] Subsoiling is one of the key technologies of conservation tillage technology. The subsoiling operation can loosen the soil, break the bottom layer of the plow, and enhance the soil water delivery capacity. The subsoiling technology can make the soil achieve the effect of "loosening without turning over", and the amount of soil movement is small . It has become a perfect farming technique at home and abroad. [0003] The subsoiler is a key component of the subsoiler, and its working status directly affects the operation quality of the subsoiler. The existing types of subsoiling shovels are mainly chisel-shaped subsoiling shovels, arrow-shaped (duck paw) subsoiling shovels, and double-wing subsoiling shovels. Since the subsoiling shovels work directly under the soil surface, the opera...

Problems solved by technology

[0004] However, during the operation of the subsoiler, due to the complex structure under the soil layer and it is difficult to observe, lateral vibrations will inevitably occur during the operation, resulting in unstable operation results. When encountering hard soil structures or hard stones , because the subsoiler shovel and the whole machine are relatively static and cannot be avoided in time, the structure of the subsoiler shovel is greatly worn and the service life is reduced
