Abstract

An object of the present invention is to provide an excavation tool that can be reliably constructed with a single tool regardless of the nature of the soil to be excavated and the presence or absence of coating in soil extraction (excavation) by human power. A fulcrum part 1, a blade edge part 2, a handle part 3, a hinge part, a fastening screw, and when the excavation is advanced, the handle part 3 interferes with a coating layer on the ground surface, and the cutting edge part 2 at the tip of the scoop. Opening and closing is impossible. At that time, the retaining screw of the fulcrum part 1 is loosened, the fulcrum part 1 is moved upward and fixed again with the retaining screw, and thereby the opening / closing operation of the blade edge part 2 with the hinge part as a fulcrum is secured. By repeating this, it becomes possible to dig deeper, and the versatility (advantage) inherent to this tool can be further improved. Further, since the shape of the cutting edge portion 2 can be changed and the handle portion 3 can be added, the work efficiency can be further improved. [Selection] Figure 1

Description

The present invention relates to a tool used for the purpose of collecting or digging a surface soil by human power.

Existing tools are mainly used in uncovered areas, and in order to dig deeply in covered areas, it is necessary to dig while enlarging the diameter of the coating layer that is the mouth, and it is possible to dig while keeping the diameter of the mouth constant. The shape was not possible.

When soil is collected in a place where there is a coating (concrete, asphalt, etc.) on the ground surface, it is necessary to make a hole in the coating in advance using a tool such as a concrete cutter as a procedure. When digging next, if the existing tool digs deeply, the tool interferes with the covering part, so the depth of the digging is examined and the mouth of the covering is opened wide in advance, or as the digging progresses, Due to the disadvantage of having to dig deeply into a mortar shape, it was not used as a tool for soil collection despite its versatility. The fulcrum movable double excavator excavator of the present invention is intended to solve the above-mentioned problems.

The present invention is roughly divided into two handle parts, a fulcrum part, and two cutting edge parts, and the fulcrum part is slidable. Furthermore, the two blade tips have a structure in which the concave portions face each other, and the two blade tips have a structure that can be collected by acting to sandwich the soil by moving the two handle parts around the fulcrum part. Yes. First, when a hole is drilled in the ground surface coating (concrete, etc.) and the fulcrum movable dual excavator type drilling tool is inserted from the tip of the blade tip and digging, the handle part interferes with the ground surface coating and cannot be digged. Therefore, by moving the position of the fulcrum portion upward, there is no interference with the handle portion, and the above problem is solved by being dug.

The method of collecting soil is roughly divided into mechanical type and human type, and this tool is a tool used in the case of human type. Conventional manual tools are mainly hand augers, but cannot be used directly when crushed stones are laid directly under the coating, and the excavation efficiency is high due to the nature of the soil. The current situation is affected. This tool is slidable at the fulcrum part, and can also be changed to a cutting edge shape or a system that can be added to the handle, making it a versatile tool with excellent work efficiency.

Form for carrying out the invention

The position of the sliding movable fulcrum is determined and fixed according to the depth of excavation. When drilling deeper, the handle part of the scoop will not open because the handle part interferes with the covering part such as concrete, so it will be possible to dig deeper by moving the fulcrum part upward each time. .

Embodiments will be described below with reference to the accompanying drawings. Reference numeral 1 denotes a fulcrum part. 2 is a blade edge part. 3 is a handle. 4b is a set screw. Reference numeral 5 denotes a coating layer.

First, the fulcrum part 1 is fixed to the connecting part between the cutting edge part 2 and the handle part 3, and the first excavation is started. As the digging progresses, the handle 3 and the coating layer 5 on the ground surface interfere with each other, making it impossible to open and close the blade 2. At that time, the four screws 4 b of the fulcrum 1 are loosened and the fulcrum 1 is moved upward. It is slid to an arbitrary position that can be opened and closed, and fixed again with the retaining screw 4b. By repeating this work, deeper excavation becomes possible.

It is a perspective view of a fulcrum movable double excavator type excavation tool. It is a fulcrum part perspective view. It is underground excavation sectional drawing.
