Description

A HARROW FOR TRACTOR

The present invention relates to a tractor harness capable of limiting the left and right swing angles of the harness plate to desired angles according to the specification of the tractor, the condition of the non-knot, or the user's choice.

In general, when cultivating rice, it is necessary to till it with Rotary prior to planting and then to flatten it with a harrow. The harness plate of the harness is composed of a center plate and right and left outer plates. When the entire harness plate is unfolded during the harrow operation, the harness plate is formed into a long (-) shape. In this state, And the tractor is moved forward to flatten the moonnon.

In flattening of non-nonson, the tractor can be tilted to the left or right according to the curvature of the bottom. In this case, to effectively planarize, it is necessary to maintain the horizontal level of the rotary or harrow attached to the rear of the tractor. Even if it is absent or not.

As a result, a tractor harness with a function for maintaining the horizontal has been developed.

The harness with the horizontal holding function combines the center part of the harness frame and the harness plate with the swing axis to make the left and right swing motion, so that the harness plate keeps horizontal and the flatness work within the range of left and right swing angles Respectively.

However, when foreign matter such as straw or soil is caught on the side of the harness plate during the flat operation of the harness, the foreign matter is sagged downward by the weight within the range of the left and right swing angles of the harness, There has been a problem in that the place where the surge plate on the side that is moved downward due to foreign matter such as straw is pitched relatively deeply as compared with the other side,

In addition, when the tractor is moved forward or backward after raising the rotary or the harrow to turn at the corner of the non-nonson, there is a problem that the driven portion of the harness plate is closer to the bottom of the non-nonson.

In addition, when the harness is raised enough to be spaced apart from the ground after the breakage of the harness, there is a problem that the one side of the harness plate is high and the other side is low so that the left and right horizontals do not fit. In this case, All damaged parts had to be repaired or replaced.

On the other hand, in recent years, the spread of tractors with greatly improved left and right horizontal functions has been increasing, and it has been necessary to adjust the left and right swing angles of the harrow according to the specifications of the tractor and the user's choice.
