Abstract

<P>PROBLEM TO BE SOLVED: To lighten a trenching utensil and save labor for a farm work. <P>SOLUTION: A steel plate is processed to try the formation of a lightened trenching hoe, but the lightened trenching hoe can not be formed. A steel plate is divided into three to five plates to form the trenching hoe which is lightened, can prevent the adhesion of the fine roots of crops to the blade edges, and further prevent the adhesion of fine soil to the blade edges. The blade of a blade bed portion 2 is formed from three or five steel plates disposed at distances of 8 to 20 mm, and the whole width distance of the hoe can be ensured. Soil loaded on the upper side of the hoe is not leaked from the distance. The steel plate of the blade portion is divided into three to five portions. Thereby, a power loaded on the blade portion is reduced, and the works of a worker can be reduced over a long time. A leveling plate 3 is adhered to the upper portion of a handle-attaching seat 1 to arrange the ditch bottom on a plane. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

Agricultural work has become necessary to reduce the weight of working tools due to the aging of farming in recent years.
By dividing the one steel plate of the blade floor into four, it is a dredge dedicated to agricultural ditching that excels in earth sashimi when grooving, further significantly improves soil separation, has excellent durability, and is extremely practical.

A variety of improvements have been made to paddles along with the development of farming work, and the shape of the blade bed and the shape of the blade edge have been improved. However, a flat blade has a basic shape and has a considerable weight.
As a result of the investigation in the publication, the problems to be solved by the prior art and the invention have been provided in various ways, but 1 is not suitable for grooving because of its narrow width and tip. No. 2 is processed with one iron plate, is heavy and is not suitable for grooving. No. 3 is processed with the same iron plate, and since the tip part is linear, the cutting edge simultaneously hits the surface of the cultivated soil, so the efficiency is extremely poor. No. 4 is not suitable for grooving because the blade base and the handle are attached at right angles and the blade base is molded into a triangle.

Problems to be Solved by the Invention

  In a general conventional scissors, the blade base is a single iron plate, and the blade tip is linear. A single steel plate is heavy in weight, difficult to reduce in weight, and the fine roots of crops adhere to the cutting edge, resulting in difficulty in grooving and deteriorating work efficiency. As the force is applied, the excavation of the soil becomes heavy labor, and the work efficiency tends to deteriorate as a result.

Means for solving the problem

  The heel is composed of 3 to 5 blades with a sharp tip, the heel body of the blade base, a knife-like leveling plate, and the handle attachment seat (櫃) at a position symmetrical to the heel body. And the blade of the blade bed portion is usually a high-tensile steel plate, with a thickness of 1 to 4 mm, a width of 20 to 40 mm, and a groove with a length of 150 to 250 mm to the handle mounting seat (櫃), The interval between the blades is 8-20mm, a fixed plate is installed between the blades, and the seat is an account (櫃) to which a wooden or resin handle can be attached. The angle with the part is 35 to 60 degrees, the leveling plate is made of one high-tensile steel plate, the length is 30 to 70 mm from the upper part of the handle mounting seat, and the tip is sharp like a blade, It is attached so that the angle with the blade bed is 150 to 190 degrees. The groove bed is characterized by being attached to a width of 140 to 180 mm.

The invention's effect

The object of the invention is to reduce the digging effort, reduce the weight of the tool, and increase the efficiency of the work.
By dividing the blade base iron plate into four sheets, the weight can be reduced, and the fine roots of the crops can be prevented from adhering to the blade edges, and further, the fine soiling of the blade edges can be prevented from adhering.
The groove bottom can be leveled by leveling the upper part of the handle mounting seat.

  In the grooving improvement rod of the present invention, the blade bed portion is composed of four blades, a blade fixing plate and an upper leveling plate. Since the blade bed uses an iron plate with a width of 30 mm, the strength can be increased by molding a concavo-convex (bead) in the center for strength reinforcement. Further, since the cutting edge is not flat as in the conventional type, but is composed of four sensitive blades, the impact on the cutting edge is dispersed with respect to the cultivated soil, so that the labor for excavating the soil is reduced.

The improved groove grooving of the present invention is composed of a handle mounting seat 1, a blade base 2 leveling plate 3 and a blade fixing plate 4. The blade bed portion is four iron plates formed by reinforcing a 280 mm long iron plate with an unevenness (bead) of 11 mm width and 185 mm length, and the tip of the blade portion is configured in a shape having independent blade tips.
A wooden cylindrical handle 5 is inserted into the handle mounting seat 1, and an improved ditch ridge is constructed from the blade bed, the leveling plate, the blade fixing plate, and the handle. In order to increase the strength of the entire blade bed, irregularities (beads) are molded, and each interval is maintained with a blade fixing plate.

  The improved grooving gutter according to claim 1 requires lighter and labor-saving work tools due to the aging of the worker, and the weight is reduced by dividing the blade bed into four pieces as compared with the conventional gutter. By preventing the adhesion of fine fine soil and dispersing the force applied to the blade edge, it is easy to bite into the cultivated soil, and it can save labor for cropping at the time of sowing and grooving adjustment of the groin, making it ideal for elderly people and wetland work It is.

  It is a perspective view of the embodiment of the present invention.   1 is an overall perspective view of an embodiment of the present invention.
