[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a disc plowing device, which enables reliable plowing by strengthening the support of the disc, processing residual plowing in the center, and preventing floating. be.

(Prior art) As a disk brochure device that is used by being towed at the rear of a tractor, a pair of left and right disk shafts each having a plurality of disks are arranged in a V-shape when viewed from above.
There is also one in which the disk is rotatable around the axis of the disk shaft. In addition, the disk is of a forced drive type that is forcibly driven through the disk shaft,
There is also a non-driven type that allows free rotation.

(Problems to be Solved by the Invention) However, in this type of disk, the disk rotates around the horizontal axis of the disk, so
In hard fields, the disks do not penetrate well and there is a problem that the disks and the entire device lift up.
Furthermore, if the disk shaft is shaped like a figure eight in plan view, residual tillage will occur in the center, and it is necessary to separately provide a narrow disk device to deal with this residual tillage. Furthermore, the machine frame is formed into a figure-eight shape in plan view in order to support the disk shaft, but it needs to have high strength so that it can withstand the large load from the disk.
Costs are getting higher.

(Means for Solving the Problems) The present invention provides specific means for solving the problems of the conventional art, in which the central transmission case 1 is

In the disc plow device, the outer ends of the left and right supports 13 are connected to each other by a connecting member 15.
A soil moving body 20 that inverts the central soil and moves it from the center to the outside or from the left and right to the center is arranged at the intermediate rear of the left and right disk shafts 16, and this soil body 20 is attached to the connecting member 15. It is.

(Function) The left and right supports 13 of the machine frame 10 have an octagonal shape in plan view, and both outer ends receive an inward force due to the load from the disk 17. The soil moving body 20 attached to this connecting member 15 has the strength to withstand the load by the connecting member 15.
is located at the middle rear of the left and right disk shafts 16,
The soil in the uncultivated part between the left and right discs 17 is inverted and moved from the center to the outside or from the left and right to the center, and the discs 17 are prevented from floating due to the soil inversion resistance.

(Embodiment) The present invention will be described in detail below with reference to the illustrated embodiment. In FIGS. 1 and 2, 1 is a tractor;
2 is the rear wheel, and 3 is the PTO shaft. Reference numeral 4 denotes a hydraulic system, which has a pair of left and right lift arms 5. 6 is a disk browser device, which is installed at the rear of the tractor 1;
It is attached to be towed and movable up and down via a three-point linkage mechanism 9 consisting of a double link 7 and a pair of left and right lower links 8. The disk browser device 6 includes a machine frame 10 and a pair of left and right disk browsers 11.
The machine frame 10 includes a transmission case 12 in the center, and a support tube (support body) 13 provided downward from both sides of the upper part of the transmission case 12 so as to have a V-shape in plan view.
and a side plate 14 extending downward from the outer end of each support cylinder 13, and the rear ends of each support cylinder 13 are interconnected by a connecting member 15. Each disc brake 11 has a disc shaft 16 rotatably supported between the transmission case 12 and the lower part of the side plate 14.
and disks 17 fixed at equal intervals to this
The left and right disk shafts 16 are arranged in a V-shape in plan view. The transmission case 12 has a built-in transmission mechanism for forcibly driving each disc shaft 16 with the power received from the upper input shaft 18, and the input shaft 18 is connected to the PTO shaft 3 of the tractor 1 via a universal joint shaft 19. connected. Reference numeral 20 denotes a digging resistor (soil moving body) for inverting the central soil and preventing the disk 17 from rising, and is arranged at the rear between the left and right disk brows 11. This digging soil plow 20 is made up of a pair of soil plate plows 21 that are stuck into the soil and used for digging, with the positions shifted back and forth, on the left and right, and each of the soil plate plows 21 is used for plowing together. It is set up so that the gravel is moved towards the center. Each clay plate plow 2
1 has a strut 22, and the strut 22 connects the connecting member 1.
It is inserted and supported in a holding fitting 23 attached to 5 so as to be vertically adjustable. The holding fitting 23 is movable in position laterally to the connecting member 15.

In the above configuration, when cultivating the field,
The power from the PTO shaft 3 of the tractor 1 moves the disc 17 of the disc plow 11 to the disc shaft 16.
The entire disk browser device 6 is towed by the tractor 1 while being forcibly controlled in the direction of the arrow a. When the disks 17 of the left and right disk plows 11 rotate in the direction of the arrow a, the disks 17 dig into the field and plow it, and the gravel 24 is turned over from left to right inward as shown in Fig. 3 and released. Go. On the other hand, there is a slight residual tillage area 25 between the left and right disc plows 11, but a pair of clay plate plows 21 are located at positions corresponding to the residual tillage area 25, and these plows stick into the soil and dig into the trench. proceed. Therefore, disk 17
Even if a force in the direction of lifting is applied from the field, this chisel plate plow 21 can prevent the disk 17 from lifting. At the same time, the soil board plow 21 can turn over the soil in the remaining tillage section 25 and move from the left and right to the center, thereby making it possible to plow the remaining tillage section 25. In this case, since the plow plate plow 21 is shifted back and forth, the soil does not interfere with the soil even though it brings the soil inward. This prevents the generation of unnecessary resistance and allows for a good plowing result. It is possible to wake up.

The clay plate plow 21 may be provided at the same front and rear positions as shown in FIG. 4, as long as the amount of soil turning over is small. That is, in FIG. 4, a rotary tilling section 26 is provided between the left and right disc plows 11, and the portion corresponding to the remaining tillage is tilled in advance. Therefore, in this case, the plowing function of the soil plate plow 21 only needs to be able to plow to a depth slightly deeper than the plowing depth of the rotary plowing section 26, and the amount of soil turning over can be reduced, so that the plowing function of the plow board plow 21 is sufficient to plow to a depth slightly deeper than the plowing depth of the rotary plowing section 26. It is also possible to provide the In addition, the tilling claws 27 of the rotary tilling section 26
The pawl shafts 28 are operatively connected to each disc shaft 16 via a bepel gear mechanism 29. Further, one disk shaft 16 is operatively connected to an input shaft 18 via a transmission shaft 32 in a chain transmission mechanism 31 in a support cylinder 13 in a chain case 30 and the like.

As shown in FIG. 5, the digging resistor 20 can sufficiently prevent uplifting if the soil plate plow 21 is made deeper than the plowing depth of the disc 27 and the rotary tiller 29.

The Horisin low antibody 20 may be equipped with soil plates 36 that cultivate soil evenly on the left and right sides, as shown in FIGS. 6 and 7. In this case, the soil plate 36 of the digging resistor 20 cultivates the tilled soil while inverting it to both the left and right sides. Therefore, it is possible to prevent the disk 17 from floating up, and to actively form the grooves 37 between the left and right gravel 24, as shown in FIG. 8, so that the plowed area can be turned into two embankments. In addition, since it is distributed to the left and right, not only does the tilled soil collide with the digging resistor 20 itself, but also the gravel 24 thrown away from the disc 17 because it is far away from the disc 17 at the rear.
There is no collision with the vehicle, and traction resistance can be reduced.

Furthermore, as shown in FIG. 9, it is also possible to combine a double-bed soil type cultivating low antibody 20 and a rotary cultivating section 26. Of course, in this case, Hori Susumu's low antibody 36
The depth of the rotary tiller section 26 is set to be deeper than the rotary tiller section 26.

Horishin's hypoantibody 20 may be other types, such as sukiyaki or the like.

(Effects of the Invention) According to the present invention, the outer ends of the left and right supports 13 are connected to each other by the connecting member 15, and the central soil is inverted at the intermediate rear of the left and right disc shafts 16, so that the soil moves outward from the center or from the left and right to the center. Since the soil moving body 20 that moves to is arranged and the soil moving body 20 is attached to the connecting member 15, it is possible to easily and inexpensively reinforce the left and right supports 13 with the connecting member 15 against the load from the disk 17. The soil moving body 20 can be easily attached using this connecting member 15, and the remaining tillage area between the left and right disc shafts 10 can be reversely tilled with this soil moving body 20, and its reversing resistance allows It is possible to prevent the disk 17 from floating up.
