Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a disc for a disc rotary for plowing and inverting tilled soil as a relatively large soil lump.

(Prior art) Conventionally, this type of disc rotary has, for example,
A disc 11 rotor body in which a plurality of curved disc-shaped isks are arranged side by side on a rotating shaft is disposed on both sides, and a residual tillage portion is located between the discs on both sides at the front part between the discs on both sides. In order to prevent this from occurring, curved disc-shaped discs are arranged in a substantially figure-eight shape in plan view and are rotatably provided, and the discs on both front sides spread the cultivated soil between the disc cultivating bodies on both sides.
There is a structure in which the grass is raised up and spread over the uncultivated land on both sides along the curved surface.

[Problem that the invention seeks to solve]

In the above-mentioned conventional configuration, the disk for processing residual tillage disposed at the front and the disks 111 on both rear sides are formed in a curved disk shape, so they are difficult to handle against hard primary growth. It is not easy to insert the soil, and if herbal medicines are scattered, the tilled soil will not penetrate well, and if the periphery of the disk becomes worn, the entire disk must be replaced. Moreover, since the soil is plowed as a large lump of soil, there are problems such as insufficient crushing and inversion of the soil embankment.

Therefore, the present invention was developed in view of the above points, and it is economical because it provides good roughening and digging into the tilled soil, ensures reversal of tillage in one call, and makes it possible to replace worn parts of the GJ. The aim is to provide discs that can be used in a variety of ways.

(Means for Solving the Problems) The present invention includes a plurality of sets of tillage reversing plates each including a main pawl and an auxiliary pawl formed independently of each other via flanges on the circumferential side of the rotating shaft. The main pawls of each set of tillage reversal plates are arranged in a circular shape and are detachably attached, and the main pawls of each set of tillage reversal plates are curved toward the rear in the direction of rotation, and the main pawls are curved toward the rear side in the rotational direction, and the main pawls are curved toward the rear side in the rotational direction, and the main pawls are curved toward the rear side in the rotational direction, and the main pawls are curved toward the rear side in the rotational direction, and there is a gap between the attachment part for the flange and the toe. An engagement recess is formed in the auxiliary claw, and the auxiliary claw is
It is engaged in the engagement recess of the main claw.

[Effect]

Since the present invention is configured as described above, when the rotating shaft is rotated, the v1 soil is moved to a predetermined size by the main pawl on the outer periphery of each of the 1 erected and reversed plates arranged and fixed in a circular shape to the rotary shaft. As well as being washed and plowed, this plowed scale is
Each plowing reversal plate is pushed and reversed by the auxiliary claws on the inner side, and the reversal is promoted, and the L glue is not thrown out to the outside.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings.

In the figure, 1 is a machine frame, and this separate frame 1 is provided with a mission case 2 which has an omitted shape when viewed from the side, and an input shaft 5 covered with a cover rest 4 is mounted on the front upper part of a vertical part 3 of this mission case 2. It is projected towards the front. Further, connecting portions 6 are provided at the front upper part and lower portions of both front sides of the separate frame 1 to connect to a suspension rock structure of a tractor.

Next, rotation @8 is rotatably provided on both front sides of the horizontal portion of the mission case 2 via a bearing body 7,
A pair of disks 10 for residual tillage treatment are arranged in a substantially V-shape in plan view and are detachably attached to the flanges 9 of the rotating shaft 8 on both sides.

Further, an output shaft 11 is rotatably mounted horizontally at the rear lower part of the horizontal part of the mission case 2, and the inner end of the rotating shaft 13 of the disc cultivating body 12 is attached to both ends of the output shaft 11 through a universal joint. The upper part of the suspension body 14 is rotatably connected to the outer end of the rotating shaft 13 of the disc cultivating body 12 on both sides via a bearing body, and the upper part of the suspension body 14 is connected to the vertical part 3 of the mission case 2. It is connected to a support frame 15 extending from both sides to the outer rear portion so as to be rotatable in the horizontal direction. Further, a plurality of discs 16 for continuously tilling and reversing the cultivated soil are detachably attached to the rotating shaft 13 via flanges 11.

Further, the output shaft 11 that rotates the rotation shaft 8 of the pair of discs 10 for processing the remaining tillage and the rotation shaft 13 of the disc 11 and the shaft 12 is connected to the input shaft 5 via an interlocking medium provided in the mission case 2. 3! T! dynamically connected.

The pair of discs 10 for tillage processing and each disc 16 of the disc tilling body 12 have a main claw 1 on the peripheral side of each flange 9.17 fixed to the peripheral side of the rotating shaft 8°13.
When a plurality of sets, ie, four sets of tillage reversing plates 20 each including a set of 8 and an auxiliary claw 19 are arranged adjacently in a circular shape, these can be attached and detached using bolts and nuts 1-21, respectively. is attached to.

The main pawl 18 of each of the tillage reversal plates 20 has a narrow plate-shaped body 22 curved toward the rear side in the direction of rotation.
A substantially semicircular engagement recess 25 is formed between the flange 9 and the flange 9, and a communicating hole 26 for bolt insertion is formed in the mounting portion 23 and communicates with the mounting hole of the flange 9° 11. A curved portion 28 is formed, which is curved laterally in an arc from the bending portion 21 halfway behind the attachment portion 23 to the toe 24.

Further, the auxiliary pawls 19 of each of the tillage reversal plates 20 are engaged in the engagement recesses 25 of the main pawls 18 and formed into a substantially fan shape, and are shaped like a net medium plate with respect to the seven lunges 9.11. A plate-shaped portion 31 on the rear side in the rotational direction of the bending portion 30 of the mounting portion 29 gradually projects inward from the mounting portion 29 and is formed by a soil repellent plate portion 32, and the mounting portion 29 has the flange 9, An insertion hole 33 for inserting a bolt that communicates with the mounting hole 17 is formed, and this mounting portion 29
An engagement recess 34 that engages with the rotating shaft 8° 13 at the inner end of the
is formed.

Therefore, the auxiliary claw 19 is formed to have a thickness equal to or thinner than the thickness of the main claw 18, and is provided at the outer edge of the engagement recess 25 of the main claw 18 with the end edge 35 of the main claw 18. Continuous part 3
In the sixth case, at least it does not protrude beyond the surface portion 31 of the main claw 18. And each 411 rotation plate 20
A recess 38 cut inwardly between adjacent outer edges of the
is formed.

In addition, in the figure, 39 is a grounding wheel that is horizontally suspended so as to be freely rotatable, and 40 is an adjustment arm that adjusts the rotation of the support frame 15.

In this structure, each connecting portion 6 of the machine frame 1 is connected to the suspension mechanism of the tractor, and the input shaft 5 is connected to the power output shaft of the tractor via a power transmission shaft. Then, while towing the machine with a tractor,
When the input shaft 5 is rotated in conjunction with the power of the tractor, the machine is advanced, and the power input from the input shaft 5 moves the pair of discs 10 for processing residual tillage in the front and the discs 111 and the rear body 12 on both sides. Each disk 1G is rotationally driven.

Then, in the front pair of discs 10, the tilled soil is tilled as a bowl of a predetermined size by the main claws 18 on the outer side of each tillage reversing plate 20, and the soil layer thus raised is A soil-repellent plate portion 32 consisting of a plate-shaped portion 31 that is guided by an auxiliary pawl 19 that is continuously provided on the inner side of the plate and that protrudes inward from its curved surface on the rear side in the rotational direction.
The soil repelling action of the earth bank gradually forces it in the reversal direction, and the lower part of the earth embankment in contact with the soil repellent plate 32 is reversed nearly downward, and along with this, the upper part of the earth embankment is also reversed. promoted. In this case, cracks are generated in the longitudinal direction of the soil layer by the pressing soil action of the soil repellent plate portion 32, and the four portions 38 between the outer adjacent portions of the main claws 18 of each tillage reversal plate 20 Cracks are generated in the +jJh direction of the upper part, and therefore, the large upper part that has been plowed is crushed into small bowl bodies, and is within the range that can be processed by the disc plowing bodies 12 on both rear sides without being thrown outward. At the time, he was released on top of Mijun's well.

Further, the uncultivated land on which the arms are left by the pair of discs 10 is continuously plowed and turned over by the discs 16 of the discs 11 and 12 on both sides. In this case, the upper part of the plowed area by the front pair of discs 10 is crushed into small pieces and reversed, so the rotation shafts 13 of the disc plowing bodies 12 on both rear sides are not pushed up by one pup, resulting in stability. The soil layer can be plowed and turned over to a predetermined depth, and the plowing body 12 of the discs on both sides
Each of the disks 16 is formed to have the same structure as the pair of disks 10 in front, so when the tilling and reversing work of the tilled soil is carried out, the soil layer is plowed and reversed through the same action as in the case described above. be. In the above case, each disk 1
0,113 not only ensures the above-mentioned tillage reversibility due to the certainty of the roughening and biting action of each main claw 18, but also contaminants such as crude drugs are reliably cut. This prevents them from becoming entangled.

In the actual eggplant example, a case has been described in which the disks 10.16 consisting of a plurality of sets of tillage reversal plates 20 are arranged on both the front and rear sides, but the disks 10.16 are not limited to this, for example, on the front, The disks 10 may be used as a pair of disks 10 for the M1 raising process, and each disk of the disk cultivating body on both sides of the rear side may be a disk of a normal shape.

〔Effect of the invention〕

According to the present invention, a plurality of sets of tillage reversal plates each formed by dividing a disk are arranged in a circular shape, so that the disk can be easily formed into a desired shape. In addition, each tilling reversal plate is constructed by combining an outer main claw and an inner auxiliary claw, so if the disc is partially worn or damaged, the main claw or auxiliary claw in the part that is worn and damaged can be replaced. Since it is not necessary to replace the whole thing with DA(), it is very simple. In addition, each tilling reversing plate has a main pawl on the outside, so that it can penetrate and dig into the tilled soil well, allowing reliable cutting and tilling. Furthermore, since the auxiliary claws are arranged inside the main claws, the plowed upper part can be reliably reversed in the reversal direction. Therefore, it is possible to provide an f-scrolling disk that can ideally turn over a dirt stop by $31.
