Scarifying machine with profiling, limiting and adjustable spear-shaped shovels

Abstract

The invention relates to a scarifying machine with profiling, limiting and adjustable spear-shaped shovels. The scarifying machine mainly comprises frames, oil cylinders, a front suspension rack, a rear traction rack, support wheels, the spear-shaped shovels and the like and is characterized in that the left and right frames and the left and right oil cylinders are mounted on the left side and theright side of the frame, the front suspension rack and the rear traction rack are mounted on the upper portion of the middle frame, and the support wheels and the spear-shaped shovels are mounted onthe lower portion of the frames. The scarifying machine has the advantages that the scarifying machine is simple in structure and easy to implement, the front suspension rack and the rear traction rack are hinged through suspension connecting rods, instant impact force, caused during machine lifting, to the whole machine can be avoided effectively, and effective machine protection can be achieved;by hinge connection formed by arranging shovel connecting rods on the spear-shaped shovels and spring acting force of return pressure springs on the spear-shaped shovels, the spear-shaped shovels canhave profiling ability to the ground surface and soil layer, a limiting effect on the spear-shaped shovels can be achieved, the spear-shaped shovels can avoid hard substances in the soil layer, the scarifying depth consistency of the spear-shaped shovels can be guaranteed, and the spear-shaped shovels can be protected; the height of support rods and the support wheels can be adjusted, so that thescarifying depth can easily satisfy agriculture requirements.

Description

technical field [0001] The invention belongs to the technical field of agricultural field management machinery and cultivating machinery, in particular to a scarifier with a profiling-limiting adjustable spear-shaped shovel. Background technique [0002] During the growth of crops, field management operations will be carried out, including soil cultivation, loosening, weeding, spraying and other operations. Due to natural reasons such as rainfall and sun exposure during the crop growth period, as well as factors such as tractors and people, the soil hardness increases, and the loosening of the soil has become an indispensable operation process for field management. In the prior art, relatively mature cultivators and soil scarifiers have been arranged, which can complete the required soil loosening operations in the growing season of crops. However, at present, all scarifiers use fixed shovels, which are not capable of profiling the ground surface. When encountering hard soi...
