Improved Tiller Steering Clutch Mechanism

Abstract

The invention provides an improved mini-tiller steering clutch mechanism comprising a box shell, an input shaft, an output shaft, a main disk hub, a driven disk and a clutch handle. The output shaft is of a half shaft structure. The driven disk comprises a pair of clutch sleeves located on the left side and the right side of the main disk hub. The clutch sleeves are installed on the output shaft. The outer ends of the clutch sleeves are provided with bead string type shifting fork mechanisms. Each bead string type shifting fork mechanism comprises a bead stopping disk, a shifting disk, a clutch line and a bead string section, wherein the side, close to the bead stopping disk, of the shifting disk is provided with a first conical work face, the clutch line is provided with a first end and a second end, the first end passes through an inner cavity of the box shell, penetrates upwards out of the box shell and then connected with the clutch handle through a second reset spring, and the second end is the loop sleeve type bead string section. The improved mini-tiller steering clutch mechanism operates stably, leftward and rightward steering operation is flexible, and the improved mini-tiller steering clutch mechanism will not conflict with the installation position of a rotary tiller blade and is simple in structure, easy to machine and low in cost, a ditching tool, a hoeing tool, a fertilizer applying tool, a ploughing tool and the like can be installed on the improved mini-tiller steering clutch mechanism, and multifunctional assembly can be achieved easily.

Description

Technical field [0001] The invention relates to a walking box of a micro tillage machine, in particular to a steering clutch mechanism of the walking box of a micro tillage machine. Background technique [0002] Due to the conflict between the traditional fork-type clutch structure and the installation position of the rotary tiller in the walking box of the prior art micro-tiller, the designer must consider setting the left-right steering clutch mechanism within the axial size range of about 20cm, which leads to design difficulties. Most micro-tillers on the market do not have a left-right steering clutch mechanism, and their field steering is inconvenient, especially for plowing the corners of the field. The operation is very laborious; in addition, due to the inconvenient steering, the rear side of the machine body is mounted to open ditching, weeding and fertilizing , Plowing and other machines are difficult to operate and difficult to achieve multi-functional assembly. The C...

Problems solved by technology

[0002] Due to the conflict between the traditional fork-type clutch structure and the installation position of the rotary tiller in the prior art micro-tiller walking box, the designer must consider setting up the left and right steering clutch mechanisms within the axial dimension range of about 20cm, resulting in design difficulties. Most micro tillage machines on the market do not have a left and right steering clutch mechanism. It is inconvenient to turn in the field, especially at the edge of the field, and the operation is very laborious; , plow and other implements are difficult to operate, and it is difficult to achieve multi-functional assembly

The Chinese utility model patent No. 20092020673.7 discloses a walking structure with a steering clutch, which adopts a traditional fork mechanism, which is inconvenient to install a rotary tiller, and can only be installed with a rear-rotary rotary tiller on the rear side of the body

There has been a tiller with a steering clutch on the market, but the structure is complicated and the cost is high

The applicant's Chinese invention patent of CN102487612B discloses a steering clutch mechanism of a micro tillage machine, which uses a beaded fork mechanism to realize the left and right steering clutch operations. The clutch sleeve works, and then the clutch sleeve is connected to the rotary tiller, which has poor running stability and is not flexible enough to operate
