Description

[Detailed explanation of the idea] This invention relates to the improvement of soil blades.

For root vegetables such as potatoes, the roots must be covered with a thick layer of soil by cultivating soil, but as conventional soil covering with soil blades was insufficient, the potatoes could become exposed and turn green, or be damaged by the wheels of tractors or harvesters. This caused the quality of the products to deteriorate.
In addition, conventional cultivating soil blades cover the soil in a concave shape to collect raindrops, making it more susceptible to disease, and the ridges have triangular cross-sections, which narrows the growing range of plants.

The object of the present invention is to provide a soil blade that covers the roots sufficiently with soil and forms the cross section of the ridge into a semicylindrical shape to expand the growing range of plants.

In order to achieve the above-mentioned problem, the soil cutting blade of the present invention is equipped with a soil scattering plate that curves outward above the left and right main plates, and the soil scattering plate scatters the soil raked up by the main plate to the roots of the crops on the ridge and covers them with soil. . Furthermore, the soil cutting blade of the present invention is equipped with a pressing soil plate behind the main plate, which presses the covered soil into a semicylindrical shape, thereby enlarging the growing area for plants.

The soil cutting blade of the present invention will be explained based on an embodiment shown in the drawings. As shown in FIG. 1, the main plate 11 of the soil blade 10 is fixed to a support 13 and has a point 9 at its tip.
is formed. The main plate 11 opens diagonally upward symmetrically from the center, and the flying plate 12 continues on its upper side.
The surfaces of the main plate 11 and the flying plate 12 are connected smoothly,
The surface of the main plate 11 is warped up, but the surface of the flying soil plate 12 following it is warped outward.

As shown in FIG. 1, a traction bar 15 is rotatably attached to the support column 13 via a spring connecting member 16, and a dosing plate 17 is attached to the traction bar. The spring connecting member 16 is a well-known rubber coupling, the outer cylinder of which is fixed to the column 13 and the inner cylinder to the traction bar 15, and the inner cylinder and the outer cylinder are in close contact with synthetic rubber filled between them. The spring connecting member 16 is set so as to constantly press the dozing plate 17 downward with a relatively large torsional elastic repulsion force. The dosing board 17 is towed by the pillar 13 and advances following the main board 11.

As shown in FIG.
5, a double hinge connecting member 18, two wing plates 21 and 22 whose lower parts are fixed to both sides of the double hinge connecting member, and an adjustable expandable structure that connects the upper parts of both wing plates. It consists of a connecting rod 19. Both wing plates 2
1 and 22 open in a V-shape, and the opening angle can be adjusted by turning the buckle 20 of the connecting rod 19 and changing the length of the connecting rod 19.

When soil cultivation is carried out by towing the support column 13 of the soil blade 10 shown in FIGS. 1 and 2 with a tractor, the soil in the ridges that has been raked up along the main plate 11 is reversed by the flying soil plate 12 and is turned over to the ridge side. As shown in Figure 3, the potatoes that were exposed on the surface are covered with the ridge soil and are prevented from being damaged by the wheels of tractors and harvesters. . Since the succeeding dosing plate 17 is always pressed downward by the torsional elastic repulsion force of the spring connecting member 16, the dosing plate 17
Both wing plates 21 and 22 of No. 7 form the ridge-covering soil into a semicylindrical shape as shown in FIG. As a result, the growing area of the potatoes expands, as shown by the chain line. The semicircular shape of the ridge covering soil can be made into a desired shape by adjusting the length of the connecting rod 19 and changing the opening angle of the wing plates 21 and 22.
