Description

[Detailed explanation of the invention] (a) Industrial application field The present invention relates to a soil excavator that excavates soil that tends to accumulate near the ridges in fields such as paddy fields and transfers it to lower areas. It is.

(b) Prior Art Conventionally, there is a known technology in which only a spiral is placed at the front of a compost turning machine and the collected compost is raised by a bucket conveyor. For example, Mikoaki
This is similar to the technique described in Publication No. 47-4849. However, there was no technology for a device to move the soil when uneven soil thickness occurs during repeated tilling operations using tractors or power tillers in the field.

(c) Problems that the invention aims to solve This invention scrapes the particularly thick part of the soil at the edge of the ridge in a horizontal state, and then flips up the scraped soil and blows it away using a blower to spread it to other low-lying areas. It is meant to be moved.

(d) Means for solving the problem The purpose of the present invention is as described above. Next, the configuration for achieving the purpose will be explained.

An upper mulching case 7 and side mulching cases 8L, 8R are arranged in the front part of the traveling device, and both ends of the earth cutting claw shaft 6 are supported by the mulching cases 8L, 8R,
Only the center part of the rear face of the upper mulch case 7 is opened as a communication port 7a to the flip-up blower 9, and the clump nails 1L and 1R are fed to the front of the flip-up blower 9 near the center of the scraping claw shaft 6. The claws 2L, 2R are planted, and the feeding claws 2L, 2R and the earthing claw 1L,
An earth removal spiral 3 is attached to the outer earth excavation claw shaft 6 of 1R, which simultaneously excavates the embankment A at the time of ridge B and performs earth filling.
L, 3R, 4L, 4R are planted.

(E) Embodiments and operations The purpose of the present invention is as described above. Next, the structure of the embodiment shown in the attached drawings and the operations of the invention will be explained.

FIG. 1 is a side view of the earth excavator of the present invention during soil transfer work, FIG. 2 is a side sectional view of the earth excavation section/transfer section, and FIG. 3 is a front view of the earth excavation section.

The overall configuration will be explained with reference to FIG.

The earth excavator of this embodiment uses a crawler-type traveling device.

However, the present invention is not limited to the crawler type traveling device C, but may be a traveling device with lug wheels, such as a rice transplanter, if the work is mainly done in paddy fields. An engine E is mounted on the body frame of the crawler type traveling device C, and a handle H for a walking operator is protruded from the rear of the engine room constituted by the engine E.

Further, in front of the crawler traveling device C, there are constructed an earth excavation section and a discharge section, which are the main parts of the present invention.

First, as shown in FIG. 3, the excavated area is surrounded on the side, top, and rear surfaces by the upper bulging case 7 and the side bulging cases 8L and 8R. Only the center portion of the rear surface of the upper dam case 7 is opened as a communication port 7a to the flip-up blower 9.

As the soil excavation section, earth removal claws 1L, 1R and feeding claws 2L, 2R are installed near the center of the earth removal claw shaft 6. In addition, on the outside of the feeding claws 2L, 2R and the earthing claws 1L, 1R, there is a earthing spiral 3 that simultaneously excavates and fills the embankment A at the time of ridge B.
L, 3R, 4L, 4R are planted.

The earth scooping spirals 3L, 3R, 4L, and 4R scrape off the soil in the high areas horizontally, collect it in the center, and send it to the flip-up blower 9 through the communication port 7a by the feeding claws 2L, 2R. . The drive of the excavating pawl shaft 6 is configured as shown in the side cross-sectional view of FIG. The flip-up blower drive shaft 16 transmits power to the bevel gear box 5.
Within the bevel gear box 5, the direction of rotation is changed and the excavating claw shaft 6 is rotated. The flip-up blower 9 has blower blades fixed around the flip-up blower drive shaft 16, and rotates at high speed to throw dirt and mud toward the elbow pipe 10 and chute 11. By adjusting the directions of the elbow pipe 10 and the chute 11, the direction of soil discharge can be changed. Depending on the soil, it may be highly sticky and lose its throwing power within the elbow pipe 10 or chute 11, resulting in the pipe becoming clogged.
In this case, the elbow pipe 10 and the chute 1
If you omit step 1 and simply scatter them over a wide area, you will achieve your goal.

In addition, in the embodiment, the soil excavation/discharge mechanism is a dedicated machine fixed to the crawler type traveling device C, but the present invention is not limited to this.
The release mechanism may be configured to be attached to the front of a management machine, tiller, or tractor as an attachment.

(f) Effects of the invention Since the invention is constructed as described above, it has the following effects.

First, the work of moving soil is quite hard work if it does not rely on mechanical power, but in rice fields, in order to plant seedlings in every corner of the field in an orderly manner, it is necessary to level the field. It becomes necessary. This was a task that could not be covered by conventional rotary tillage equipment, but by using the soil excavator of the present invention, it is possible to easily transfer high areas such as corners and ridges to lower areas. You will be freed from hard labor.

Second, the feeding claws 2L and 2R are arranged in the center,
Earth-moving claws 1L, 1R are arranged on the outside, and earth-moving spirals 3L, 3R, 4L, 4 are placed on the outside.
This arrangement allows the thickened soil surface to be excavated horizontally, and the excavated soil is blown away by the flip-up blower 9, making it possible to cover a wide range of low-lying areas with soil.
