Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an in-situ inversion and co-creation method for inverting a bank cut from soil in a field, and improvements to an in-situ inversion and co-creation device used to carry out the method.

Inversion of cuttings cut from the soil in the field is done by forming long derivatives such as plows or pear moldboards or spatulas, which invert the cuttings while moving them laterally. This method involves the movement of soil by sequentially inverting the next adjacent weir into the groove formed by the weir, and the weir is inverted on the spot to prevent soil movement. It's not a thing.

Inverting an embankment cut from the soil on the spot requires only one working body to cut and invert the trench; If the derivative that is to be rotated is formed long in the direction of movement of the workpiece, and if there is even a small part of the derivative that can get caught on the embankment, it will only cause the collapse to collapse and prevent the reversal from being carried out. Otherwise, the weir would become clogged in the middle, making it impossible to work, so it is theoretically possible to form the guiding surface in a smooth continuous state and guide the cut platform while gradually reversing it. Although it is possible to do so, it is not practical because the length of the work body including the guide will be large, a wide headland is required, and as mentioned above, it is troublesome to manufacture the guide to guide the fence. There is no such thing. In addition, when inverting the weir on the spot, it is difficult to install multiple working bodies side by side in the horizontal direction and attempt to invert multiple mounds lined up horizontally adjacent to each other at the same time. As shown in FIG. 1, the length -e of the diagonal line of <fiL cut by the workpiece is longer than the distance between the adjacent and parallel workpieces W..., so the cutting [L is the second]
As shown in the figure, in the process of reversing 90 degrees, the
It was considered impossible because the L would create a jam on the guiding surface and cause it to collapse.

As mentioned above, the object of the present invention is to
The in-situ reversal work of F, which previously required a long conductor with a precisely finished guiding surface, is now possible with a new and conventional method that is extremely short and does not require precision machining. The purpose of this project is to propose a new method that makes it possible to simultaneously invert multiple rows of dark strips that are adjacent to each other on the spot, which was thought to be impossible.

Therefore, the present invention has been completed based on the knowledge obtained through various experiments and studies in order to achieve the above-mentioned object.

In other words, when a moat cut from the soil is turned over while being guided by a dielectric, if vibration is applied to the derivative and the moat is vibrated, the soil properties of the moat change and the embankment becomes elastic like konnyaku. In addition, the vibration to make it elastic can be a vibration in one direction, and if the direction of the vibration is the back-and-forth direction, which is the direction in which the induction body is guided, then the elasticity Even if the guiding path made of a derivative is narrow and has an unreasonable shape that would normally cause blockage, it will flow smoothly in the guiding direction. It is now possible to pass through the weir without causing collapse, and the on-spot reversal of the weir can be performed using a taxiway that is narrower than the width of the embankment on either side and is extremely short from front to back. When inverting a cut moat while guiding it with a vibrating dielectric to invert it in place, after the platform has been inverted to 90 degrees, the remaining angle is This was done based on the knowledge that reversal (usually up to about 135 degrees) can be performed relatively easily.For this reason, in the present invention, An in-situ inversion tillage method in which a tower cut from soil in a field is turned over while being guided by a derivative in a state where it has elastic properties through vibration, and a tower cut from soil in a field is , at least until the combustion is reversed approximately 90 degrees while being guided by a derivative that mainly vibrates back and forth,
