Gear missing prevention device for rotary tillage rake

Abstract

The invention relates to a rotary tillage harrow disorder gear resistance device. The device is arranged in the speed changer of a tractor, which mainly comprises a fixing box, a spacing press rod, a spacing plate, a rotary sleeve and a fixing shaft, wherein the spacing press rod is arranged between the shifting forks of the working gear and the reverse gear of a gear box, the fixing shaft is connected to both lateral walls of the box body of the gear box, the rotary sleeve is sheathed outside the shaft, and the spacing plate is connected between the spacing press rod and the rotary sleeve. The invention realizes the work state of no disorder gear during the operation of the rotary tillage of a rotary tillage harrow, and improves the safety performance of a rotary tillage harrow; the invention prolongs the service life of parts of a rotary tillage, and eliminates noise generated during disorder gear; moreover, the device has the advantages of simple structure, no need of changing the arrangement of other assemblies of the gear box, and convenient assembly and disassembly, and the device can be installed on both new tractors and old tractors. Moreover, the invention does not need changing the operation habits of operators, is popular among operators, and can be popularized easily.

Description

technical field [0001] The invention relates to a rotary cultivator driven by a tractor, in particular to a device for preventing disorderly blocking of a rotary cultivator. Background technique [0002] The rotary tiller driven by tractor is an important machinery for agricultural cultivation and is widely used. The rotary tiller has played a positive role in the efficient increase of agricultural production. The rotary cultivator works through the power obtained by meshing the gears of the clutch with the gears of different gears in the gearbox of the tractor. Therefore, under normal circumstances, the shift handle is controlled to complete the gear at a specific position by controlling the different shift forks in the gearbox. The meshing with the clutch gear realizes the working state of rotary tillage and stop of the rotary tiller. However, in order to improve the working efficiency of the rotary tiller, people often increase the width of the rotary tiller as much as p...

AI Technical Summary

Problems solved by technology

However, in order to improve the working efficiency of the rotary tiller, people often increase the width of the rotary tiller as much as possible. The reality caused is that even if the rotary tiller is in the working state, sometimes there will be a reverse disorder Phenomenon

When the rotary cultivator is out of gear, the disordered collision between the gears will not only make a lot of noise, but also easily damage the tooth corners, so the gears must be repaired and replaced frequently
