Description

  The present invention is connected to the rear part of the tractor, inserted by digging a blade into the lower end of the long one that has grown on the straw of the field, and held in a block shape with the surrounding soil around the long part, The present invention relates to a vibration device for a long digging body of a harvesting device that digs up without being scratched while being levitated toward the surface.

Various long harvesting devices have been proposed. The long one that grows grows to a depth of about 1 meter toward the basement, and the harvesting work is heavy labor. At the same time, the long one is broken by the compressive force at the time of digging, and the surface skin is broken due to the collapse of dredging and soil. Has the property of being easily scratched. In order to solve these problems, digging blades are sown into the bottom of the long one that has grown, held in the shape of a block together with the surrounding soil around the long one, and lifted toward the rear, without damaging the long one. Japanese Patent No. 2865252 and Japanese Patent Application Laid-Open No. 2006-25601 have been proposed as devices to be dug up by the same application.
According to the former disclosed configuration, the conveyor belt constituting the rear part of the digging blade body rotates at a speed corresponding to the work advance speed of the tractor, so that the cultivated soil has less occurrence of distorted earth pressure, Move backwards while maintaining the vertical position as it is grown in the cultivation soil.
Therefore, the long one is dug out with almost no damage such as breakage.
According to the latter disclosed configuration, since the resistance force from the soil received when towing the digging device is reduced even when the tractor is long, the tractor can be pulled even with a relatively small power. On the basis of these known configurations, the same applicant was admitted that the compression force when the upper surface of the inclined digging blade body entered the lower part of the cultivated soil block was aimed at further speeding up. On April 23, 2013, we proposed Japanese Patent Application No. 2013-103500.

Japanese Patent No. 2865252 JP 2006-25601 A

According to the embodiment of the specification of the aforementioned Japanese Patent Application No. 2013-103500, the grown long thing is excavated on both sides and deeply plowed to the lower end of the long thing, and the long part is further removed by the digging blade body whose rear part is inclined upward. In a long digging device that floats along with cultivated soil and moves backward, the tractor is characterized in that the blade portion of the digging blade body is arranged close to the lower end of the excavation chain for excavating both sides of the long one. A long harvesting device that connects to
In addition, the boom is provided with a length adjusting means so that the height between the lower end of the excavation chain and the digging blade body can be adjusted, and the rear end of the digging blade body is flush with the digging blade body. The structure of a long harvesting device connected to a tractor provided with a drop assist plate that slightly vibrates is disclosed.
After the above-mentioned application, in the same application, we continued the test research in a large-scale field in Aomori Prefecture and Hokkaido, which are long main production areas. As a result, even in one field, conventional soil and clay It was found that the ground or sandy soil layer was mixed.
The challenge of this development is to aim for speeding up long digging work with a large tractor while maintaining intactness, but on sandy soil, on the other hand, the vibration action of the fall assist plate of the digging blade body I found out that it would be harmful.
For example, in normal field soil, oscillating the latter half of an inclined digging blade has the effect of reducing the load on the tractor, but in soils with sandy fluidity, the digging blade has a slight vibration effect. , The long history of the long thing will be washed away, the long claw's holding block will collapse, it will flow into the gaps on the left and right sides of the digging blade, the long one itself may fall down and break and damage the skin Turned out.

To solve the above problem,
Long digging equipment that excavates both sides of the grown long thing and deep-plows it to the lower end of the long one, and further lifts the long one together with the cultivated soil by the digging blade body with the rear inclined upward and harvests it. In this case, a drop auxiliary plate that vibrates on the same plane as the digging blade body is provided at the rear end of the digging blade body, and a clutch device for separating power is provided in the middle of the vibration driving means of the drop auxiliary plate. A vibration device for a digging body of a long harvesting device connected to a tractor, characterized in that the vibration drive of the drop assist plate itself can be selected in a field where a long bamboo shoot grows.
The tip of the digging blade body is formed to have an inner width of the excavation chain on both sides, and the rear half of the digging blade body is configured to be wide so as to overlap the groove width of the excavation chain. Provided is a vibration device for a long digging body digging body connected to a tractor.

A vibration device for a digging body of a long harvesting device connected to a tractor according to claim 1, wherein the vibration assisting clutch device for the fall assist plate is configured so that an auxiliary worker who extracts a long floating surface can be operated while observing the soil state. I will provide a.
Further, a vibration driving clutch device for the fall assist plate provides a vibration device for a long digging body of a harvesting device connected to the tractor according to claim 1 configured to be operable by a driver of the tractor.

Because it is configured as described above, the deep plowing groove made by the excavation chain on both sides and the long cutting edge of the digging blade body are pierced into the lower end and simultaneously formed a cultivation soil block with a U-shaped cross section Because it is lifted sequentially and moved backward, the blade portion of the conventional digging blade does not generate a compressive force in the lower layer of the cultivated soil block and is digged up at the rear end of the digging blade. A fall auxiliary plate that vibrates on the same plane as the blade body is provided to reduce the propulsion resistance of the digging blade body during excavation at the time of excavation. In addition, a drive-separation clutch device is provided in the middle of the vibration drive of this drop assist plate, so that a long-time vibration transmission separation can be selected by the assistant, so that sandy soil with high fluidity can be selected. Immediately isolate the vibration drive in the area to prevent the sandy soil from flowing away. Moreover, since the vibration drive is connected and operated in ordinary soil, it can be appropriately adapted to the mixed soil layer in the same field, and the damage and abrasion due to the collapse of the lower layer of the cultivated soil block are remarkably reduced. Further, in the field of the same section, it is convenient because the tractor driver can select the on / off operation of the vibration driving of the fall assist plate according to the soil characteristics such as soil hardness and sandy.
