Description

A HARROW FOR TRACTOR

The present invention relates to a tractor harrow, and more particularly, to ensure a smooth drainage while maintaining the grip of the harrow piece during the harrow work, and to make the harrow work effectively to the left and right outer parts of the harrow does not pass the rotorbator. It relates to a tractor harrow that can prevent the formation of soil pits.

In general, when cultivating rice fields, harrow work is performed to evenly cultivate munon that has been ground with a plow or a rotorbait before planting. At this time, the tractor and rotorbate are generally used to push Munon's soil outwards. There was a difficulty.

During the harrow work, the water in front of the water is smoothly drained through the harrow and moved to the rear. Most of the existing harrow is not drained smoothly, so the water that is pushed out as the water flows outward is pushed out to the outside. In the end, even though the harrow work did not work effectively harrow, such as not flat.

In order to solve such problems, the present applicant has applied for the technology of the Republic of Korea Patent Publication No. 10-2010-0013339 (name of the invention: tractor harrow, published date: 2010.02.09). The above technique is to place the lower end of the center plate of the harrow higher than the lower end of the left and right outer plate so that the water of Munon goes to the bottom of the middle plate during the harrowing operation to facilitate the drainage.

However, the above technique requires that the midplane is positioned higher than the outer plate so that the height of the middle plate must be calculated accurately, and the inclination angle of each harrow piece coupled to the middle plate and the outer plate is required. In addition, in the case of the left and right outer plate drainage is made, but as the harrow work is made in contact with the ground, the drainage is not made smoothly, there was a problem that the water and soil is pushed to the outside of the outer plate.

In addition, the above technique has a problem that the bending of the bracket portion connecting the center plate and the outer plate, as well as the phenomenon of hitting the rotor rotor side when the folding of the outer plate due to the step of the middle plate and the outer plate occurs.

The present invention was devised to solve the above problems, to maintain the traction of the harrow piece even when the harrow plate is separated from the ground during the harrow work to smoothly work as well as drainage, the harrow piece from the rear It is to provide a tractor harrow which is formed to be inclined so that the mouth side of the drain passage is invisible to crush the Munon's soil passing through the outer plate to prevent the formation of ridges, as well as to more actively guide the soil and water inward. .

The configuration of the present invention for achieving the above object is coupled to the rotor bay frame and the frame for connecting the harrow, consisting of a center plate and the left and right outer plate and the spaced apart from the rear surface of the harrow plate to form a drain passage In the tractor harrow consisting of a plurality of harrow pieces that are coupled to, the harrow plate is formed so that the center plate and the left and right outer plate are located on the same line to be horizontal when viewed from the front or rear, the bottom surface during the flattening operation of Munon The drainage space is formed to be spaced apart therebetween, the harrow piece is provided with one side end is inclined downward toward the other end while being coupled to the rear of the harrow plate, the other end protrudes further than the lower surface of the harrow plate It is characterized in that the flattening operation of the Munnon while being buried in the ground.

At this time, the harrow piece is composed of a central harrow piece coupled to the center plate, and the outer harrow piece coupled to the outer plate, the outer harrow piece is to the other end so that the mouth side of the drain passage is located outside the exit side The cover plate is formed to be inclined inwardly and extends from the rear surface of the outer plate to cover a portion of the upper side of the drain passage so as to be coupled to the outer harrow pieces adjacent to the drain passage.

In addition, the harrow piece coupled to the rear of the outer plate of the harrow piece is formed to be inclined inward toward the other end so that the mouth side of the drain passage is located outside the exit side, when viewed from the rear of the outer plate of the drain passage It is preferable that the mouth side is formed so as not to be identified by being hidden by the adjacent harrow piece.

According to the present invention configured as described above, through the drainage space formed below the harrow plate during the harrow work, the water of Munon can be smoothly drained to prevent the phenomenon of being pushed to both sides of the harrow, and the inclined structure of the cover plate and the harrow piece Due to the effective separation of the soil, there is an effect that can prevent the formation of dirt.

Hereinafter, with reference to the accompanying drawings will be described in detail a tractor harrow of the present invention.

As shown in Figure 1, the tractor harrow according to the present invention is a device used to connect to the rotor bantor 10 is installed in the rear of the tractor, the cylinder 15 and the frame for connecting the harrow to the rotor 10 It consists of a harrow plate 30 coupled to the 20, and a plurality of harrow pieces 40 coupled to the rear surface of the harrow plate 30.

The harrow plate 30 is composed of a central plate 32 and the left and right outer plate 34, and is provided to move up / down by the operation of the cylinder 15 to be operable in the driver's seat, the cylinder and the outer plate is connected Is connected to the link 17 is formed so that when the harrow plate is raised by the rod inlet of the cylinder, the outer plate is rotated forward and folded.

The harrow pieces 40 are spaced apart from each other and are coupled to form a drainage passage 45 therebetween, and the spacing of the harrow pieces is not too wide so as to increase the grounding force on the ground of the harrow piece while preventing the drainage passage 45 from being too wide. In other words, the width of the drain passage is preferably formed within twice the width of the harrow piece.

Here, the harrow plate 30 is formed to be horizontal when the center plate 32 and the left and right outer plates 34 are located on the same line and viewed from the front or the rear (see FIG. 2). It is designed to be firmly coupled to to minimize flow during harrow work, and to prevent the phenomenon or shaking from colliding with other parts or rotorbatter when moving by folding the outer plate to minimize damage and to move stably.

At this time, the harrow plate 30 is a harrow operation is performed in a state that the drainage space 36 is formed between the bottom surface of the non-non-non-marrow at the time of the harrow work as a predetermined height without touching the ground as shown in FIG. Therefore, the harrow piece 40 is provided to protrude downward more than the lower surface of the harrow plate 30 so that the flat work is grounded to the ground of Munon.

Thus, in the harrow of the present invention, when the harrow work, the harrow plate passes by being spaced apart from the ground, and the harrow piece is grounded on the ground, and the munon water enters under the harrow plate and is discharged to the rear. The water is drained smoothly without being pushed outwards.

The harrow piece 40 is provided to protrude rearward while one side end is coupled to the rear surface of the harrow plate 30, it is provided to be inclined downward toward the other end. In addition, the harrow piece 40 is formed to be inclined so as to be guided inward after passing the non-non-water.

Specifically, the harrow piece 40 is composed of a central harrow piece 41 coupled to the center plate, and an outer harrow piece 42 coupled to the outer plate. At this time, the outer harrow piece 42 is formed to be inclined inward in the direction in which the central plate is provided toward the other end so that the mouth side of the drain passage 45 is located outside the outlet side so that the drained water is guided inward.

Here, in the case of the middle plate of the harrow plate 30, since the rotor is provided in front of the rotor plate 10, since the soil is crushed by the rotary operation by the rotor bait, there is no need to separately grind the soil, the outer plate In the case of the rotary work as it passes through the soil as it is, the soil is not crushed may be formed.

4 and 5, the rear plate of the outer plate 34 extends from the rear of the outer plate 34 to cover a portion of the upper side of the drain passage 45 to prevent the formation of the ridges. The cover plate 50 is provided to be coupled to the outer harrow pieces 42 on both sides adjacent to the 45.

Therefore, the piled up or agglomerated Munon soil is pulverized by the blade portion of the outer harrow piece while the outer harrow piece passes, and the Munon soil becomes flat while being caught by the cover plate 50 in this process.

The cover plate 50 may be provided between the upper surface or the lower surface of the outer harrow piece 42 or between the upper surface and the lower surface, and the length thereof may vary depending on field conditions such as a non-non state.

In addition, in another embodiment, when the cover plate is not provided, as shown in FIG. 6, the outer harrow piece 42 has the other end such that the mouth side of the drain passage 45 is located outside the outlet side. It is preferably formed to be inclined inwardly, when viewed from the rear of the outer plate 34, it is preferable that the outer harrow piece is formed to be inclined so that the mouth side of the drain passage 45 is hidden by the adjacent harrow piece 40 is not identified.

Therefore, the soil introduced into the mouth side of the drain passage 45 is crushed by the lower blade portion of the outer harrow piece, it is broken and flattened while hitting the side surface of the adjacent outer harrow piece in this state.

The tractor harrow of the present invention configured as described above has the center plate and the outer plate protruding downwards longer while the center plate and the outer plate are positioned on the same line so that the middle plate and the outer plate are not in contact with the ground during the harrow work. The water is drained down the outer plate, and the harrow piece is grounded and buried in the ground, crushing the soil as well as working smoothly.

In particular, the harrow of the present invention is to guide the water or the soil introduced into the drainage passage to guide the inside to prevent the formation of the pit by grinding the soil.

In this way, the present invention is an invention that can prevent the phenomenon of forming the earth jungle or pike while smoothly draining the water is most important in the harrow work.
