Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a residual extraction device for forming a cocoon on an cultivated land and collecting a fruit or the like grown on the cocoon and then removing a trunk or a stock remaining on the cultivated land.
[0002]
[Prior art]
The work of digging up and extracting the strains that were grown and cultivated in the persimmons was extracted and discarded one by one. Also, if the roots of these strains touch the soil, they may grow again, and it was necessary to extract the root strains and turn them over or to draw them on a heat-retaining film laid on the soil surface. These manual operations are difficult, and devices for mechanically extracting root stocks and weeds have been developed for a long time.
[0003]
For example, what is described in Japanese Patent Application Laid-Open No. 59-118005 is a cigarette stock sampling device, in which a rotating device linked to a driving device of a prime mover is arranged in front of a cultivator, and linked to this rotating device. The roots are cut by two kinds of cultivating claws that rotate at, and the trunk is dug up and the trunk is extracted and left on the ground.
[0004]
In addition, what is described in Japanese Patent Laid-Open No. 2000-4603 is a dredging trunk excavation device such as a dredge that cuts and excavates the remaining trunk such as dredging in a dredge on a machine mounted with a prime mover such as a cultivator. A device that is equipped with a blade that vibrates back and forth in the soil and a fork-like vibrating body that vibrates up and down in the soil, and that leaves the trunk, etc. on the ridge after cutting the root. It is.
[0005]
[Problems to be solved by the invention]
Even if root cutting and soil sieving were carried out in the soil, the roots of the dug up strain would come into contact with the soil and roots would come out again. In particular, in the case of cocoon roots, when the vine grows and touches the soil, there is a risk that the roots will be stretched.
Nowadays, a heat insulation film (such as a vinyl sheet) is laid on the surface to cover the surface. For this reason, rotating the rotating body on the saddle as described in Japanese Patent Application Laid-Open No. 59-111005 and Japanese Patent Application Laid-Open No. 2000-4603 makes the above-mentioned heat insulating film laid entangled with the rotating body and becomes impossible to rotate. Or, in the state where the roots of the remaining trunk were cut or left behind on the surface of the soil, the roots might come into contact with the soil and sprout.
An object of the present invention is to provide a remaining stock extracting device that can efficiently and efficiently extract a root stock using a conventional simple cultivator. Another object of the present invention is to provide a residual stock extracting apparatus that can securely pinch a residual trunk, extract it from soil, and place it on a film surface of a saddle surface.
Furthermore, the present invention provides a remaining strain extraction device that can extract a remaining strain from soil without involving a spread film.
