Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a tillage method in which a large number of trenches cut from soil are reversed from left to right in the direction of the furrow core G to perform furrow tillage.

Furrow plowing, in which a large number of thickeners are turned over toward the ridge core, has been practiced for a long time. This is done by turning the plow over and over again, and there is no known tillage method that allows this to be done in one step. This is accomplished by hawk plowing, which is carried out with a plowing machine, by inverting the plowed bottle to the part located next to the groove formed by plowing the bank. Since the plowing machines are arranged in a T-shape, if multiple tillage machines are arranged in parallel so that the work can be carried out in one stroke, two plowing machines facing each other from the left and right across the furrow core will be installed in the center of the machines. One problem is that the tillage machine is unable to work because it turns over the bottles at different places, and two tillage machines face each other with the furrow core in between. The present invention solves these problems by arranging the levees at intervals of O, so that there is a place for them to go, and the uncultivated land is removed from the center of the ridge, preventing ridge plowing. The purpose of this study is to propose a new method that enables furrow plowing to be carried out in a stepwise manner.

In order to achieve this objective, the furrow tillage method of the present invention uses a tillage machine that inverts the bank cut from the soil on the spot so that the direction of inversion of the tilled bottle faces the iron core. They are arranged side by side in multiple rows on the left and right, and the tillage working machines are used to light a single furrow by turning the multiple bottles around the iron core at the same time. That is.

Next, embodiments will be described in detail with reference to the drawings.

is a vertical cutting blade that cuts the soil substantially vertically so as to make a substantially vertical cut in the front end of the machine body (1) that travels by being towed by a towing vehicle T such as a tractor or by itself. (
2) and (2) are mounted in parallel at intervals corresponding to the left and right widths of the weir to be formed, and these vertical cutting blades (2)
・A horizontal cutting blade (3) is installed behind the interval (2) to cut the soil approximately horizontally at a depth position corresponding to the bottom edge of the vertical cutting blade (2) and the door (2). At the negative end of the horizontal cutting blade (3), a lower corner of one side of the L cut from the soil by the vertical cutting blade (2) and the horizontal cutting blade (3) is attached. The mold board (4) is pushed up diagonally upward on the other side as shown in Fig. 4 A, Mouth, and C, and the 1JllL is approximately rotated (reversed) in the groove M formed by cutting the fiL. The other side G on the opposite side to the mold board (4) is inverted by the mold board (4), and a pushing member (5) is installed to press down the upper surface of the other side of L. , Furthermore, the horizontal cutting blade (3) has been inverted approximately 90 degrees to the rear position and is now in an approximately upright state as shown in FIG. 3 above! A mold board (6) is provided to push the lower end side of L from the side opposite to the mold board (4) in the reversal direction so as to push it in the reversal direction and guide the reversal by approximately 45 degrees or more. A pressing member (7) is provided that presses the upper end of the JIL that has been inverted by the mold board (6) in the inverted direction from the opposite side of the mold board (6), and by this series of members, the soil is removed. The cut [L is inverted approximately 135 degrees (or more) (-<+vt J-+ t

〉It is constructed by arranging so that the inverted direction of the IjllL faces the iron core of the ridge to be formed, and arranging them in parallel on the left and right in multiple rows with the same phase. In addition, each tillage machine A has a horizontal cutting blade (3) that cuts the weir from the soil in cooperation with its vertical cutting blade (2), and a horizontal cutting blade (3) that cuts the cut residue. A mold board (

8), and as a result, as shown in Figure 4, when the WL cut from the soil is approximately inverted, the properties of the L are made elastic. Convert it to [width d of the groove M formed by plowing L]
This is so that fiL, whose diagonal line l is longer than that of fiL, can be reversed approximately 90 degrees within the slot M, as in the old case. The vibration device 00) consists of a crank wheel I that is pivotally supported on the fuselage (1), one crank pin provided thereon, a reciprocating rod 03 with one end connected to the pin (one end), and a crank wheel I that is pivotally supported on the fuselage (1). ) is connected to the other end of the reciprocating rod t131 by a connecting shaft (151) provided on the fulcrum shaft (I4) and a connecting shaft (151) provided in the intermediate bendable joint part 06.
