Practical cultivator

Abstract

The invention discloses a practical cultivator which comprises a rack, an engine, a speed changing box, a handle assembly and a rotary tillage work mechanism. The engine, the speed changing box and the handle assembly are arranged on the rack. The rotary tillage work mechanism comprises a power output shaft, a tool apron fixed to the power output shaft and rotary blades fixedly arranged on the tool apron. The speed changing box comprises a box body and a transmission speed changing mechanism arranged in the box body. The practical cultivator is characterized in that the transmission speed changing mechanism comprises a gear changing shaft fixedly provided with a shifting fork, a power input shaft, an intermediate wheel shaft, a transmission shaft, a power input wheel, a gear shifting gear, an intermediate wheel installed on the intermediate wheel shaft, a transmission wheel and a chain wheel, wherein the power input wheel and the gear shifting gear are installed on the power input shaft, and the transmission wheel and the chain wheel are installed on the transmission shaft. The transmission shaft is further sleeved with a duplicate gear in a clearance mode, and the duplicate gear comprises a reverse gear and a small gear. The practical cultivator is provided with a reverse gear mechanism, the reverse action of the whole cultivator can be easily achieved, and the practical cultivator is complete in cultivating coverage and long in service life.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a practical cultivating machine. Background technique [0002] The practical cultivator is powered by a small diesel engine or gasoline engine. It has the characteristics of light weight, small size, and simple structure. It is widely used in dry land, paddy fields, orchards, etc. in plains, mountains, and hills. The practical cultivator can be used freely in the field, which is convenient for users to use and store. It saves the trouble of large agricultural machinery not being able to enter the mountainous fields. It is the best choice to replace cattle farming. The defect existing in the existing practical cultivating machines is that most of the transmission gears only have forward gears, and there is no reverse gear. When farming in the farmland, it will be very laborious and inconvenient to operate if the complete machine is reversed; The gears and axles in the machine have poor ...

AI Technical Summary

Problems solved by technology

The defect of existing practical cultivating machine is that most of the transmission gears only have forward gears, and there is no reverse gear. When farming in the farmland, it will be very laborious and inconvenient to operate if the complete machine is reversed; The gears and axles in the machine have poor wear resistance, are easy to wear or break during the transmission process, and have a short service life; during rotary tillage operations, the land corresponding to the gearbox is easy to fall off, and the tillage coverage is not comprehensive, leaving dead spots easily
