As shown in the figure, a harness plate according to an embodiment of the present invention is directly or indirectly connected to a harness frame 20 and an elevating cylinder 25 at the rear of a rotary 10 for a tractor, 30 and an outer plate 40 provided on the right and left outer sides of the center plate 30. The blades 50, 55 and the cover plate 60 are provided on the lower surfaces of the center plate 30 and the outer plate 40, ) Is installed.

The harness frame 20 is provided in a pair so as to be parallel to each other and is installed to hinge a front end on the rotary 10 or as a separate structure to a mounting structure 15 installed on the upper part of the rotary, Can be installed by being hinged. At this time, a horizontal line may be provided so as to connect the rear ends of the serration frame 20 arranged in parallel with each other.

The front end of the lifting cylinder 25 is hinged to the center plate 30 and the front end of the lifting cylinder 25 is hinged to the upper portion of the rotary 10 or when the mounting structure 15 is installed, And is hinged to a cylinder bracket provided on the mounting structure 15 so as to move the center plate 30 up and down.

A plurality of blades 50 and 55 are provided on the lower surfaces of the center plate 30 and the outer plate 40 and the cover 50 and 55 are provided on the upper surfaces of the blades 50 and 55, The plate 60 is installed.

The blades 50 and 55 are installed at predetermined intervals in the front-rear direction so as to be coupled to the support frames 32 and 42 and the harness pieces 34 and 44. As shown in FIG. 2, 44, and one blade can be coupled between the harness pieces 34, 44, and the intervals between the blades are the same.

Of course, it is of course possible to couple two blades to the lower portion of the harness pieces 34, 44.

The blades 50 and 55 are provided in a direction perpendicular to the support frames 32 and 42 and the front ends of the blades 50 and 55 protrude forward of the support frames 32 and 42 Respectively. The reason for this is to allow the churning or hardening of the soil to be smoothly carried out without the formation of bones, and to enable the foreign matter such as straw or grass to be effectively buried in the ground.

At this time, a cover plate 60 is installed to cover the upper part of the front ends of the blades 50 and 55 while connecting the blades to each other, and the cover plate 60 is installed, .

The cover plates 60 are provided at the front of the support frames 32 and 42 and the rear plates 34 and 34 are provided at the rear of the support plates 32 and 42. [ 44 are provided so that the center of gravity is matched with the center of gravity, so that the eccentric load is not applied, thereby increasing durability.

In addition, due to the formation of the clay loam space 62, the clay loam space 62 serves as a compartment, so that the water introduced into the space is trapped during the churning operation, It is possible to solve the problem that the young moth roots can not be smoothly moved due to the clay that has been stuck to the lower surface of the support frame and becomes hardened.

At this time, it is preferable that a drainage part 65 is formed between the cover plate 60 and the support frames 32 and 42. The drainage section 65 may be formed by separating the cover plate 60 from the support frames 32 and 42 and forming a drainage section therebetween. The cover plate 60 is supported by the support frames 32 and 42, Holes may be formed at predetermined intervals in a state in which they are formed so as to be connected to the discharge ports.

The reason for forming the drainage portion 65 is to solve the problem that the surrender operation is not performed smoothly because water over the upper side of the cover plate 60 is generated when there is a lot of water in the non-condensing operation to be. That is, the water trapped in the confounding space 62 is allowed to escape through the drainage part 65 so that the drainage can be performed smoothly, and the foreign matter such as straw or grass can be buried more easily due to smooth drainage.

In addition, since the drainage unit 65 is formed, the operator can directly view the operation of the tractor while operating the tractor, so that the operation can be more accurately performed, and the efficiency of the operation of the harrow can be improved.

The cover plate 60 has a cross-sectional shape of 'a', '⊃', and '⊃' when viewed from the right so as to reinforce strength by connecting the blades 50 and 55 without interfering with the straw- ',' - ', or the like.

It should be noted that the lid plate 60 and the cover plate provided on the center plate 30 and the cover plate provided on the outer plate 40 are separated from each other as the outer plate 40 is rotated and folded , And the cover plate (60) provided on the center plate (30) is preferably divided into at least two pieces.

The reason for this is that attachments such as brackets are coupled to the center plate 30, and these attachments and the cover plate 60 are divided and formed in order to avoid interference or collision due to interference or collision. Since the center plate 30 is formed to have a relatively long length as compared with the outer plate 40, when the cover plate 60 is formed as one unit, the center plate 30 is excessively long and the productivity is lowered. 60 are divided and formed.

The blades 50 and 55 are formed to protrude forward as compared to the center plate 30 and the outer plate 40. The blades 55 coupled to the outer plate 40 are coupled to the center plate 30 The blade 50 is longer than the blade 50 and protrudes forward.

This is because the center plate 30 is pressed against the door of the rotary while the tractor is moving while the outer plate 40 is pushed together with foreign substances such as straw or the like pushed outward from the rotary or tractor wheels, The length of the blades 55 provided on the outer side plate 40 is longer than the length of the blades 50 provided on the center plate 30 so as to project further forward.

At this time, the bottom inclination of the blades 50 and 55 is formed to have the same or similar inclination angle as the inclination of the bottom of the support frames 32 and 42. Therefore, when the angle of the harness plate is inclined to perform the harness operation, the harness can be efficiently buried while the straw is being buried.

As shown in FIGS. 6A to 6D, the blades 50 and 55 may be provided with reinforcing portions 57 by bending the upper portion of the blades or by forming ribs on the side surfaces. Further, the surface of the blade may be embossed to provide the reinforcing portion 57.

As shown in FIG. 6B, the ribs formed on the side surface of the blade may form ribs protruding along the longitudinal direction on one side of the blade to form ribs. As shown in FIG. 6C, The ribs can be formed by forming grooves on one side surface and protruding the other side surface.

By forming the reinforcing portion 57, it is possible to reduce the weight of the blade as well as reinforce the blade, thereby achieving a cost saving effect.

The blades 50 and 55 are installed between the lower portion of the harness pieces 34 and 44 and the harness pieces 34 and 44 as described above.

Prior to the detailed description of the blades 50 and 55, the harrow pieces 34 and 44 of the present invention are coupled to the support frames 32 and 42 at regular intervals so as to smoothly discharge the harrow, A spacing space is formed between the harness pieces 34 and 44.

Therefore, the blades 50 and 55 are provided with the first blades 50a and 55a positioned below the harness pieces 34 and 44 and the first blades 50a and 55a positioned below the harness pieces 34 and 44, Two blades 50b and 55b.

The first blades 50a and 55a serve to burrow foreign materials including straw and the second blades 50b and 55b are used to prevent foreign matter including straw from being buried, And it plays a role of crushing the clay soil passing through with water.

As shown in FIG. 5A, the second blades 50b and 55b may include an embedding piece 51 vertically coupled to the support frames 32 and 42 for burring and crushing foreign matter including straw, And a front end integrally formed on an upper rear side of the burying piece 51 and having a front end coupled to a rear surface of the supporting frames 32 and 42 to prevent a curb formed between the front and rear harness pieces 34 and 44 And a prevention piece 52.

At this time, an attachment fixing hole 52a is formed in the hedge preventing piece 52, so that other attachments (not shown) necessary for the harrow operation can be attached and used.

5b, the second blades 50b and 55b according to another embodiment may be formed of a burying piece (not shown) that is vertically coupled to the support frames 32 and 42 for burring and shoveling foreign matter including straw, And an attachment fixing member 54 integrally formed on the upper side of the rear side of the bending piece 53 and formed with an attachment fixing hole 54a of a predetermined size.

The attachment fixing pieces 54 are formed to be coupled to the rear surfaces of the support frames 32 and 42 but are not formed in an area large enough to prevent the formation of the gangs like the block preventing pieces 52, It may be formed so as to form an attachment fixing hole 54a.

The outer plate 40 of the present invention is coupled to both ends of the center plate 30 so as to be coupled to the connection arm 45 hinged to one side. One side of the elevating cylinder 25 and the connecting arm 45 is connected by a link member 27 for rotating the outer side plate 40.

The outer plate 40 is rotated when the lifting and lowering operation of the lifting cylinder 25 is performed. When the lifting cylinder 25 is lifted, the outer plate 40 is folded forward and folded. When the lifting cylinder 25 is lowered, It is unfolded and is in a state of being dated.

At this time, the height of the outer plate 40 is adjusted so that the height of the outer plate 40 can be adjusted so as to adjust the overall horizontality with the center plate 30.

A bolt connecting piece 46 is formed on the other side of the connecting arm 45 and a fixing bushing 47 is formed on a lower surface of the connecting arm 45. A connecting arm 45 is connected to the bolt connecting piece 46, And an upper portion of the outer frame 40 is fixed to the upper portion of the support frame 42 by a bracket 70 for hinge coupling of the adjustment bolt 70 The bracket 74 and the fixed bushing 47 are coupled to each other by a hinge shaft 76.

The hinge shaft 76 is installed in the forward and backward directions so that the outer side plate 40 is vertically rotated.

The horizontal angle of the harness plate can be adjusted by the installation of the adjustment bolts 70, the fixing nuts 72 and the hinge shafts 76. In particular, since the advancing angle of the blades is not changed, .

That is, conventionally, when the angle of the outer plate is adjusted, the outer plate is hinged to both sides of the center plate, and the end portions are slightly or backwardly moved with respect to the hinge point so that the outer plate is bent forward or backward So that the progress angle of the straw buried means provided on the lower side of the harrow is changed not in the direction perpendicular to the traveling direction of the tractor but in the inside or the outside direction so that the chilling work is not smoothly performed, However, the present invention has been able to prevent such a problem by improving the structure.

According to the present invention configured as described above, it is possible to smoothly carry out the churning work by preventing the formation of the brick during the churning operation by allowing the hardened or agglomerated soil to be burnt together with the foreign matter such as straw buried through the smooth drainage during the churning work .

Further, by adjusting the vertical height of the outer side plate 40, it is possible to make the advancing direction of the tractor coincide with the angle of the blades 50 and 55, thereby enabling foreign substances such as straw to be buried smoothly.
