Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a mudguard device for a rotary tiller, and in particular, Smooth tilling work by eliminating sagging conditions and suppressing the adhesion of discharged mud to the rear cover. This invention relates to a mudguard device for a rotary tiller that can perform the following functions.

0002

[Conventional technology]

Conventionally, a rotor is attached to the rear of a tractor so that it can be raised and lowered via a three-point linkage mechanism. On Lee tilling machines, there is a In addition to providing a rear cover that can freely move downward, a rubber plate is installed on the upper surface of the inner wall of the rear cover. A mudguard device is known that is equipped with a mudguard plate to suppress the scattering of discharged mud. It is being

0003 However, with this one, only the top end of the mudguard is attached to the rear cover. Therefore, the rear cover will sag due to its own weight, increasing the amount of discharged mud attached to the rear cover. However, the distance between the mudguard plate and the rotary claw of the rotary tiller is inevitably narrow. Therefore, the discharged mud adhering to the mudguard plate is rolled up again by the rotary claw. There is a concern that the soil will be washed away, and the effectiveness of tilling work will be reduced due to the reduced ability to remove mud. This had the disadvantage of significantly lowering the rate.

0004

[Problem that the idea aims to solve]

This invention was devised in view of the above-mentioned actual situation and to eliminate the drawbacks of the conventional ones. The purpose of this is to suppress the adhesion of discharged mud to the rear cover. In addition, the distance between the mudguard plate and the rotary tiller is kept constant to ensure smooth discharge of mud. The purpose is to provide a rotary tiller that can ensure the following.

[0005]

[Means to solve the problem]

In order to solve the problem, the technical means adopted by this invention is to A rotary tilling section is installed in the rotary tilling section, and a rear cover that covers the rotary tilling section is installed as above. It is attached to the rear of the work equipment frame so that it can move up and down, and the mudguard plate can be attached to the rotary It should be placed facing the direction of discharging mud from the tilling section, and along the inside wall of the rear cover. It is characterized by the ability to maintain

[0006]

[Effect]

Therefore, according to the present invention, it is possible to suppress the adhesion of discharged mud to the rear cover. In addition, the spacing between the mudguard plate and the rotary tiller is kept constant to ensure smooth discharge of mud. It can be carried out.

【Example】

The configuration of the present invention will be described in detail with reference to an embodiment shown in the drawings. In Figures 1 and 2, 1 is a three-point link mechanism at the rear of the tractor (not shown). A rotary tiller mounted on the rotary tiller so that it can be raised and lowered through the rotary tiller. A rotary tiller is provided with a plurality of rotary claws 2, 2... on the front part of the working machine 1. The section 3 is constructed along the lower surface of the work machine frame 4 extending in the left-right direction of the machine body. At the same time, support frames 5, 5 made of hollow pipes are placed at a predetermined interval to support the work machine frame. It is pivotally installed at the rear of the arm 4 so as to be able to move up and down. In addition, one of the rotary tillage sections 3 Inside the chain case 6 attached to the side, there are rotors that pivotally support the rotary claws 2, 2... - The tally shaft 3a and the drive shaft 7 pivotally supported in the work machine frame 4 are connected via a chain 8. The drive force transmitted from the tractor (not shown) drives the rotary The claws 2, 2, . . . are configured to be rotationally driven.

[0008] A reinforcing pipe 9 is installed at an intermediate position between the support frames 5, 5, and At the rear end of the frames 5, 5, there is a tool bar on which a tail wheel, ridge erector, etc. can be attached and detached. -10 is suspended horizontally.

[0009] 11 is a rotary cover that covers the upper surface area of the rotary tiller 3; - The front edge of the tally cover 11 has a bag shape that is folded back and forth in the left and right direction in front of the aircraft. A hollow portion 11a is formed to protrude forward of the rotation locus of the rotary claws 2, 2... Therefore, the strength against deformation, twisting, etc. of the rotary cover 11 body is increased. At the same time, the mud a is scattered forward due to the rotation of the rotary claws 2, 2... can be prevented.

0010 The rear cover 1 is connected to the rear edge of the rotary cover 11 via a connecting fitting 12. 3 is pivotally supported to be able to move up and down, and the upper surface side of the rear cover 13 and the rotary cover are The tilting position of the rear cover 13 can be adjusted by the adjustment mechanism 14 provided between the rear part of the bar 11. It is designed to be adjusted. In addition, the connecting fitting 12 is provided with a rubber plate material in the tilling width direction of the rotary tilling section 3. The upper end of the mudguard plate 15 is screwed, and as shown in FIGS. 3 and 4, The plate bombs 16, 16... are mounted at predetermined intervals, and the rear cover 13 The mudguard plate 15 is configured to be elastically supported from below between the inner wall surface 13a of ing.

[0011] In the configuration as described above, when plowing work is done during standard work, rotary The mud a tilled by the tilling section 3 is guided to the rear end 13b of the rear cover 13. However, the mud a scattered by the rotary claws 2 and 2 is The mudguard plate 15 prevents mud from adhering to the inner wall surface 13a of the rear cover 13. Ru. Further, the mudguard plate 15 is supported from below by plate-shaped bullets 16, 16... Therefore, there is no sagging of the mudguard plate 15 due to its own weight, and the rotary The gap between the claws 2, 2 and the mudguard plate 15 is maintained constant, and the mudguards adhere to the mudguard plate 15. The mud a is not caught up in the rotary tilling section 3 again, and the rotary tilling section The tillage work according to step 3 can be carried out smoothly and efficiently.

0012 In addition, during shallow plowing work, the rear cover 13 can be adjusted to the connecting fitting 1 by the adjustment mechanism 14. When the mudguard plate 15 is positioned downward with the center of rotation The plate-like bullets 16, 16... are maintained in a state where they are appropriately supported between the side wall surface 13a, and the A stable mud protection effect is ensured. In addition, in this embodiment, a mudguard plate 15 made of a rubber plate material is installed in the tilling width direction, The mudguard plate 15 is configured to be supported from below by plate bombs 16, 16... However, the present invention is not limited to this, and as shown in FIGS. 5 and 6, Platy bullets 16a, 16a... are installed inside the mudguard plate 15, and the mudguard plate 15 itself If the structure is configured to apply elastic force, the installation work of the mudguard plate 15 will be facilitated, and the The configuration of the lower surface of the rear cover 13 can be simplified, and mud clogging caused by scattered mud a can be prevented. be able to.

[0013]

[Effect of the idea]

In short, the present invention has a rotary tiller mounted below the work machine frame. , place the rear cover that covers the rotary tilling section above and below the rear of the work machine frame. In addition to being movable, the mudguard plate is installed in the direction of discharging mud from the rotary tiller. The mudguard plate is placed facing the rear cover and is supported along the inner wall surface of the rear cover. Even if only the upper end is attached to the rear cover, the discharge of mud to the rear cover will be prevented. While suppressing adhesion, it is possible to prevent the mudguard from sagging due to its own weight. At the same time, the distance between the mudguard plate and the rotary tiller can be maintained constant, and the mudguard Prevents discharged mud adhering to the board from being caught in the rotary claws, resulting in smooth mud removal. It is an extremely useful fruit that can promote drainage and improve the efficiency of tillage work. It has a practical effect.
