AI Technical Summary

Technical Problem

Existing rotary tillers are prone to tooth and blade breakage when encountering stones in the soil. Furthermore, when tilling in dry, hardened soil, the torque on both sides of the cutter shaft is unbalanced, affecting the tilling effect.

Method used

It adopts a double-sided symmetrical transmission structure, connecting the drive shaft and the cutter shaft through a transmission ring and a transmission belt. When the transmission ring and transmission belt encounter a stone, they spin freely to avoid power transmission to the cutter shaft, thus balancing the torque on both sides of the cutter shaft. Bevel gears are used to ensure that the transmission shafts are in opposite directions, providing power in the same direction.

Benefits of technology

It effectively avoids chipping and breakage of the cutter shaft and gears, ensuring balanced torque even in hardened soil and improving tillage efficiency.

Abstract

本实用新型涉及农用机械技术领域,且公开了旋耕机。该旋耕机,包括:连接架,所述连接架的下方固定安装有连接板,所述连接板的上方固定安装有连接环,所述连接环的内部固定安装有固定管,所述固定管的右端固定安装有传动箱,所述传动箱的前侧固定安装有侧盖,驱动轴在转动时能够通过传动环以及传动带带动固定轴转动,在固定轴转动时,与固定轴之间构成固定连接的驱动齿轮会通过连接齿轮带动刀轴转动,而驱动轴右侧的传动轴通过传动环、传动带直接与刀轴构成转动连接,由于传动带与传动环之间嵌合连接,在刀轴撞击至石块时,传动环与传动带之间将会产生空转,此时动力将无法输出至刀轴,从而避免刀轴以及齿轮结构产生崩刃与崩齿的情况。
