Generally, a plow is a farming tool used to plow a field or a field by using a tractor as a power source. The plow is ground up to remove weeds or mix the remaining crops grown with the soil. It makes the land porous and provides the effect of making sowing or crop cultivation easier.

The tractor plow is a multiple plow having at least three plow blades, which are mainly used from three plows with three plow blades to eight plows with up to eight plow blades depending on the horsepower of the tractor. The crests are divided into two-use plows that rotate left and right.

Such a conventional tractor plow is provided with up to eight plow blades in a single mainframe having a limited width, thereby limiting the area that can be worked on a single run of the tractor and narrowing the working width to perform work while reciprocating several times. As a result, efficiency and efficiency are reduced, as well as excessive consumption of tractor fuel and extended working hours.

In view of these problems, the width of the mainframe can be expanded to provide a plurality of plow blades to increase the speed and efficiency of tilling. However, in this case, the width of the mainframe is too wide to drive other vehicles. There is a risk of safety accidents as well as the damage of the plow due to the contact with the temporary construction of the surroundings, and when the plow is stored, the occupancy area is large, which leads to difficulties in storage.

The present invention is to actively solve a number of improvements included in the conventional tractor plows described above, while installing the foldable frame can be quickly and easily unfolded / foldable according to the operator's choice on both ends of the main frame, the foldable frame In order to use the plow blades to change the arable land by installing a separate plow blade, and to be able to fold compactly during normal driving or storage as a problem of the invention.

The present invention is rotatably installed on both sides of the upper end of the main frame with a plurality of plow blades as a means for solving the above problems, the rotating shaft is rotated with the folding frame unfolded in contact with the front end of the main frame Integral connection via a piece, the rotary shaft is devised a technology that can be selectively reversed rotation in accordance with the operation of the folding control means.

In addition, the present invention devises a technique of integrally attaching a rotary lift to the rotary shaft, and freely connecting the other side of the rotary lift to one side of the folding frame.

According to the present invention, when the folding frame is attached to the separate plow blades are selectively installed on both ends of the main frame to be combined to expand / fold, the plow can be quickly and easily wide while spreading the folding frame to both sides. By converting, it is possible to change a large area of arable land at one time, which greatly improves work efficiency and efficiency, reduces the number of operation of the tractor, reduces fuel consumption, and shortens working time.

In addition, when driving on a general road using a tractor or storing a plow when not in use, the folding frame is folded to the upper part of the main frame in a compact manner to enhance safety and prevent damage to the plow and provide a very easy effect of storage. do.

It will be described a preferred embodiment for implementing the solution of the problem to be solved by the present invention in more detail.
