An agricultural loosening device with adjustable shrinkage of crushing teeth

Abstract

The invention discloses an agricultural soil loosening device with the adjustable crushing tooth shrinkage. the agricultural soil loosening device comprises a base, a cylinder body and a soil loosening device; the soil loosening device is composed of a disc and a rotating disc, and a clapboard is fixedly arranged in the disc, the partition plate divides the interior of the disc into an upper chamber and a lower chamber, the rotating disc is rotationally arranged in the lower cavity, and three connecting rods are hinged to the periphery of the rotating disc, and three crushing teeth are arranged on the outer wall of the lower cavity in a sliding mode, and the other ends of the crushing teeth and the connecting rod are hinged to each other; a circular gear is rotationally mounted in the upper chamber, and an electric push rod is further fixedly mounted in the upper chamber, the telescopic end of the electric push rod is fixedly connected with the rack, and the rack and the circular gearare meshed with each other. According to the soil loosening device, the soil loosening device with the disc structure is arranged, and the rotating disc is installed inside the soil loosening device in a rotating mode., and the crushing teeth are driven to contract or extend out through the rotating disc, so that potential safety hazards brought to a user are avoided while the crushing teeth are protected, and the survival rate of the crops is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an agricultural loosening device with adjustable shrinkage of crushing teeth. Background technique [0002] Agriculture is an industry that produces food and industrial raw materials by cultivating animals and plants. Agriculture belongs to the primary industry, and the science that studies agriculture is agronomy. The objects of labor in agriculture are living animals and plants, and the products obtained are the animals and plants themselves. We use the growth and development laws of animals, plants and other organisms to obtain the approval of various departments through artificial cultivation, collectively referred to as agriculture. Agriculture is the basic product that supports the construction and development of the national economy. [0003] The soil is easy to agglomerate after a long time, which reduces the air permeability of the roots, as if the root...
