In general, when cultivating rice fields, it is a plowing process to evenly cultivate munones that have been plowed or rotated before plowing.

Conventional harrows have been disclosed in which the harrow itself maintains a constant height with respect to the ground of Munon even if the tractor shakes due to the curvature of the munon floor during the harrowing operation. There was a problem.

In addition, as described in the Republic of Korea Patent No. 423996, when the conventional harrow is set up so that the rear end of the harrow plate is lowered to the ground when the soil is to be pulled by the soil, in this case usually in the shape of a saw blade. Since the trailing edge of the old harrow plate is dug, the blade-shaped valleys and ridges remain in the place where Munon's soil was dug. There was a problem that the harrow was damaged, such as the back end being bent while digging. This is because the lower end of the frame is connected to the lower surface of the supporter, such as the lower angle of the plate to raise the soil so that the rear end of the plate to pull the soil.

In addition, as described in the Republic of Korea Patent No. 742099, yet another conventional harrow was able to dig the soil into the harrow even when the tractor retracts to the function of the conventional harrow, but a variety of configurations are added to the complex and soil Digging or pushing the top of the harrow plate, dirt or foreign material remains or stuck in the operation is not smooth operation can occur, the link structure of the harrow connection structure consisting of a plurality of lifting rods rather than a square frame structure Therefore, unlike when the tractor pulls forward soil, when the tractor pushes backward soil excessively in one direction of the harrow, there is a risk that the lifting rod is twisted and the harrow is damaged. There is still a problem of damage to the harrow, such as the formation of valleys and pits or the trailing edge of the harrow board during the digging. there was.

In addition, in the conventional harrow, when flattening in the field, when using a harrow with a saw blade-shaped harrow plate, valleys and ridges are generated, and when using a harrow with a straight elongated harrow plate, valleys and pits occur. Therefore, there was a problem that farms could not choose whether to form valleys and pits according to the work situation at that time.

The present invention was devised to solve the above problems, and an object thereof is to form a first stopper in contact with a subframe on an angle bracket, so that the harrow maintains a constant angle of the harrow work with respect to the ground of the non-non flatness. To provide a harrow for tractors to improve.

Another object of the present invention is to form a second stopper in contact with the subframe in the angle bracket, when the front of the harrow plate composed of the support by one stopper drag the bottom of the Munnon when dragging or pushing the soil with the harrow The two-way operation of the plate is carried out at the same time to prevent the damage of the pieces or the blades coupled to the rear end of the plate, and the front of the plate is composed of a long, long support when dragging or pushing the soil. The dirt is dug smoothly, and the tractor reverses and pushes the dirt to the harrow so that no dirt or foreign substances remain on the upper operating part of the harrow plate so that it does not interfere with the operation of the harrow.
