Tractor, Loader, Work Tool, Coupling
Description
The present invention relates to a manual coupling device for a tractor work machine, and more particularly, the operator can easily attach and detach the work machine to the loader's loader, thereby increasing the use efficiency and efficiently for the loader regardless of the size and shape of the work machine. The present invention relates to a manual linkage device for a tractor work tool that can be attached and detached to maximize a range of applications.
Generally, a loader is installed at the front of the tractor, and various types of work machines are selectively attached to and detached from the tip of the loader according to the purpose and purpose of the farm.
Since the loader and the working machine have different specifications and detachable methods depending on the manufacturer, there is an inevitable problem of purchasing the loader and the working machine of the same manufacturer or using separate modifications.
Therefore, the present inventor has devised a domestic utility model registration No. 0413755 "connector for tractor work machine" as a solution to solve the above problems.
However, the above-mentioned "connector for tractor work machine" can be easily attached or detached to the loader by the operator rotates the lever formed on one side to the front or rear, on the contrary, between the engaging member by the repeated rotation of the lever The load is concentrated on the connecting frame for connecting in the horizontal direction, which leads to deformation.
In addition, the above-mentioned "connector for tractor work machine" is a stone or various foreign materials, etc. in the process of using the work machine hits the connection frame, this causes the connection frame is broken or cause interference during the rotation of the lever operating efficiency is It has a limited disadvantage.
In particular, the aforementioned "connector for tractor work machine" is a connection frame is easily damaged and broken to provide a cause of the safety accident that the heavy work machine falls to the ground as the binding force with the loader is terminated.
Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art,
An object of the present invention is to provide a manual linkage device for a tractor work machine that allows the operator to easily operate and detach the work machine to the loader.
Another object of the present invention is to provide a manual connection device for a tractor work machine that can adjust the installation interval and position according to the size or shape of the work machine and loader.
The present invention is a manual connection device for a tractor work machine is formed between the work machine (A) and the loader (C), to enable the detachable,
The front side forms a plurality of
The present invention has the effect of improving the work efficiency because the operator can easily operate the detachable work of the work machine and the loader.
In addition, the present invention can secure the binding force between the work machine and the loader by minimizing damage or deformation caused by the inflow of stones or various foreign matters, so that the cause of the safety accident can be prevented in advance.
In particular, the present invention is very useful invention that can increase the scope of application because the left and right intervals can be adjusted according to the connection position of the work machine and the loader.
