Coulter arrangement mode for achieving rotary cultivator cutter shaft falling

Abstract

The invention provides a coulter arrangement mode for achieving rotary cultivator cutter shaft falling. The coulter arrangement mode is characterized in that a cutter base adjacent to a connecting base or a linking shaft device is at least provided with two falling special cutters, blades of the falling special cutters face the connecting base or the linking shaft device, and the falling special cutters extend to the lower portion of the connecting base or the linking shaft device. A sliding cutting soil spitting plough is installed below a middle transmission reduction gearbox, a slant cutter disc is provided with 2-4 falling special cutters, and the falling special cutters extend to the lower portion of the reduction gearbox. The sliding cutting soil spitting plough and the falling special cutters are utilized to dig away soil below the reduction gearbox, the connecting base and the linking shaft device, and falling of the reduction gearbox, the connecting base and the linking shaft device is achieved; the ineffective rotation radius of a coulter is reduced, and the cultivation depth of a rotary cultivator is deepened. Meanwhile, when the requirement of the same rotary cultivation depth is met, the length of the rotary cutter can be effectively shortened, the power dissipation of the rotary cultivator is reduced, and the service life of the rotary blade is prolonged.

Description

technical field [0001] The invention relates to the field of rotary tillers, in particular to an arrangement of coulters for realizing the sinking of the rotary tiller shaft Background technique [0002] A rotary tiller is a tillage machine that is matched with a tractor to complete plowing and harrowing operations. It has been widely used because of its strong soil breaking ability and flat surface after plowing. At the same time, it can chop up the root stubble buried below the surface, which is convenient for the seeder to operate and provides a good seed bed for later sowing. At present, the maximum plowing depth of the rotary tiller is generally 14-16cm, which cannot meet the requirements of deep plowing and burying stubble. [0003] The tillage depth of the rotary tiller is determined on the one hand by the radius of rotation of the cutter shaft, and on the other hand by the length of the rotary tiller blade. The increase of the blade length of the rotary tiller is n...

AI Technical Summary

Problems solved by technology

The increase of the blade length of the rotary tiller is not only restricted by the strength of the blade, but also the increase of the blade length will inevitably increase the power consumption significantly.

In addition, there is a problem of mechanical interference between the reduction box that provides power for the cutter shaft, the connecting seat for fixing the cutter shaft, the coupling device, and the soil surface, which makes the rotation radius of the cutter shaft have an invalid radius, resulting in the ineffective tillage depth of the rotary tiller. improve
