Soil loosening machine with relatively long service life

Abstract

The invention discloses a soil loosening machine with a relatively long service life. The soil loosening machine with the relatively long service life comprises a handle, a machine frame and a mud guard fixedly arranged on the lower end face of the machine frame. The soil loosening machine is characterized by further comprising a motor casing, an electromotor, two supporting plates, an assemblingbox, an assembly space, a rotating shaft, a transmission device and a rotating device, wherein the motor casing is fixedly arranged on the lower end face of the mud guard, the electromotor is fixedlyarranged in the motor casing, the two supporting plates are fixedly arranged on the lower end face of the motor casing separately, the assembling box is fixedly arranged on lower end faces of the twosupporting plates, the assembly space is arranged in the assembling box, the rotating shaft is fixedly arranged at an output end of the electromotor, the transmission device is fixedly arranged at thelower end of the rotating shaft, and the rotating device is arranged at the lower side of the motor casing. The rotating device comprises two fixed annular blocks, a cylindrical sleeve, a supportingrod, four turnover plates, a transmission assembly, limiting assemblies and a start-up assembly, wherein the cylindrical sleeve is fixedly arranged on the external surface of a fixing tube, the four turnover plates are fixedly arranged on the external surface of the supporting rod uniformly along a circumferential direction, the transmission assembly is used for driving the four turnover plates torotate, the limiting assemblies are used for limiting the four turnover plates, and the start-up assembly is arranged on the cylindrical sleeve.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a scarifier with long service life. Background technique [0002] Because agriculture provides the basic products that support the construction and development of the national economy, it is a sector that uses land resources as its production object. It is an industry that produces food and industrial raw materials by cultivating animal and plant products. Agriculture belongs to the primary industry. When agriculture is cultivated , it is often necessary to use a ripper to turn the land to facilitate the planting and growth of crops; at present, when the existing ripper encounters hard soil, the power shaft of the motor on the ripper will be subjected to a relatively large force when turning the soil. Large resistance will cause damage to the motor, thereby reducing the service life of the motor. Contents of the invention [0003] In order to overcome the deficiencies of...
