The present invention relates to a connecting device for a tractor work machine, and more particularly, it is possible to attach and detach a work machine such as a bucket and a bale tong to the loader's loader more quickly and conveniently, thereby improving the work efficiency as well as the size and shape of the work machine. The present invention relates to a tractor work linkage device for increasing the range of application by allowing the detachable to be efficiently attached and detached.

In general, the front of the tractor (D) is provided with a loader (C) for the front and rear, up and down movement through the joint movement, the various ends and the shape of the loader (C) depending on the purpose and use of the farmhouse. Various kinds of work machines A are selectively installed and used.

However, the loader (C) and the work machine (A) are different from each other according to the manufacturer and the fastening method is not compatible (互換), so in order to use this efficiently in farms, you need to purchase the loader and work machine of the same manufacturer unnecessarily. Inevitably, the loader (C) and the work machine (A) have had an inefficient problem that must be used through separate modification work.

In particular, as described above, the cost for the purchase and renovation of the loader (C) and the work machine (A) is passed on to the farm as it is, thereby resulting in a double burden of economic burden.

Therefore, in the related art, in order to solve the above problems as well as to efficiently attach and detach the loader (C) and the work machine (A),

A front loader for tractor 2 section frame, a work coupler and a work machine mounted to the section 2 frame, a bottom support rod for connecting the left and right section 2 frames, and a support plate extending the inner plate of the section 2 frame; An upper hanger attached to the support plate, a support plate attached to the inside of the support plate and having an assembly pin guide tube, an assembly pin inserted into the hole of the support plate, an opening / closing device of the assembly pin, and a work machine side hanger adapted to the hanger, A loader-side coupler device comprising a two-way stable switchgear having a guide tube and a locker provided on the assembly pin as an opening-and-closing device of the working plate corresponding to the assembly pin of the support plate.

It has a structure in which a work machine and a loader are connected.

However, the "loader coupler device" should be operated between the loader and the narrow space of the work machine to operate the handle formed therein, in which the load and wear or corrosion of the work machine terminates the binding force of the loader and falls Occurs frequently, which has a problem of threatening the worker's personality for steering wheel operation.

In addition, the "loader coupler device" described above requires a worker to enter a narrow space of a work machine and a loader in order to operate a handle, thereby reducing work efficiency due to the hassle and inconvenience of work, and incomplete posture in a narrow space. In the case of manipulating the furnace handle, older workers have a disadvantage in that severe physical force is generated in the joints such as the waist.

In particular, since the "loader coupler device" is not formed in the left and right and up and down direction gap adjusting means for connecting the work machine and the loader having different specifications, the compatibility and applicability are not considered at all because of this There is a limit that the use efficiency and range of use can be extremely limited.

Therefore, it is convenient to use, and the attachment and detachment operation of the work machine and loader can be made more securely, and the tractor work machine connecting device which can increase the convenience of use by selectively applying irrespective of the size of the work machine and loader than ever before is possible. All are urgently needed.

As such, the present invention has been devised to solve the conventional problems as described above, and the present invention avoids the inconvenient and inefficient structure in which a conventional worker enters a narrow space of a work machine and a loader to operate a handle, thereby allowing the worker to move outside of the work machine. In order to provide a connection device for a tractor work machine that can improve the use efficiency and operation reliability by allowing a simple and convenient operation to detach the work machine and the loader.

In addition, the present invention is to provide a connection device for a tractor work machine to increase the range and convenience of use because it can be applied by selectively adjusting the installation interval and position irrespective of the size and shape of the work machine and loader.
