Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a rotary earth excavator attached to a riding tractor.

(Prior art) Conventionally, in order to erase the traces of the tractor's wheels, an earth shuffling device protruding from the earth crushing rotor was installed.
It is described in Japanese Utility Model Publication No. 52-53608 and is well known.

That is, when A in FIG. 2 is a plowing plate and B is plowing soil, the portion of the tractor wheel mark C is concave as shown in the figure.

(Problems to be Solved by the Invention) The reason for this is thought to be that the problem is as shown in FIG. That is, when the wheel D steps on the tilled soil B, it presses the tilled soil B laterally, so the soil pressed by the wheel D escapes to both sides of the wheel D, forming slightly raised parts E, E.

The above-mentioned known example is provided with a mulching device that protrudes from the crushing rotor, but it is dangerous to provide a mulching device that protrudes from the crushing rotor.

(Means for Solving the Problem) Therefore, the present invention provides a rotary earth excavator 6 having a width T larger than the width t of the riding tractor 1 at the rear of the riding tractor 1.
, a large number of soil digging claws 8 protrude approximately radially from the rotating shaft 7 for tilling and crushing the ground surface, and a return screw installed horizontally between the soil digging claws 8 for leveling the traces of the traveling device 4 of the riding tractor 1. The gist of this is a structure of a rotary earth excavator which is attached to a riding tractor in which the plate 9 is slightly inclined so as not to protrude outward from the earth digging claws 8.

(Example) An example of the present invention will be described with reference to the drawings.
1 is a riding tractor, 2 is a driver's seat, 3 is a steering wheel, and 4 is a traveling device. The traveling device 4 is formed by tires or crawlers. A rotary earth excavator 6 is attached to the rear of the riding tractor 1 via a connecting fitting 5. Width T of rotary earth excavator 6
is considerably larger than the width t of the riding tractor 1, and also digs up the tracks trampled by the traveling device 4.

Thus, the rotary earth excavator 6 is formed by attaching a large number of earth digging claws 8 to the outer peripheral surface of the rotating shaft 7. A return plate 9 approximately parallel to the shaft 7 is provided so as to be slightly inclined so as not to protrude outward from the earth digging claw 8. Since the return plate 9 is slightly inclined, it returns the raised portions E and E due to the inclination.

(effect) Next, we will discuss the effect.

Since the present invention has the above-described configuration, when the riding tractor 1 moves forward, the traveling devices 4, 4 trample and compact the cultivated soil in the field, and as shown in FIG. moves in the left-right direction and moves forward while forming the raised parts E, E.

However, in the present invention, return plates 9, 9 are installed between the soil digging claws 8, 8 of the rotary soil excavator 6, and are slightly inclined so as not to protrude outward from the soil digging claws 8. It acts to return the raised parts E and E to their original state at the same time as tilling, and therefore does not cause the above-mentioned defects.

(Effects) Conventionally, for the purpose of erasing tractor wheel marks, a mulch device was installed that protruded from the soil crushing rotor.
It is described in Japanese Utility Model Publication No. 52-53608 and is well known.

The above-mentioned known example is provided with a mulching device that protrudes from the crushing rotor, but it is dangerous to provide a mulching device that protrudes from the crushing rotor.

However, in the present invention, a rotary earth excavator 6 is provided at the rear of the riding tractor 1, and the rotary earth excavator 6 has a width T larger than the width t of the riding tractor 1. A large number of soil digging claws 8 that protrude to till and crush the ground surface, and the soil digging claws 8
The return plate 9, which is horizontally installed between them and smoothes the traces of the running gear 4 of the riding tractor 1, is slightly inclined so that it does not protrude outward from the digging claws 8. C, crushed soil without C,
Can be cultivated.

(b) Since it is installed so that it does not protrude beyond the earth digging claw 8, there is no danger.

C. Since it is installed at a slight inclination, it works well.

D. Since it is attached to the soil digging claw 8 itself, it is easy to attach.

This effect is achieved.
