JP3080066U - Sword-tip shovel with a serrated projection at the tip - Google Patents

Abstract

(57) [Summary] (Corrected) [Problem] With a sword tip shovel conventionally used, when excavating work such as a hard solid ground unexpectedly, the shovel is repelled and cannot achieve its original purpose.
Therefore, at present, excavation work is performed after chipping using a pickaxe or the like. On the whole, there is a demand for the development of a construction tool capable of performing a simple work setup. In the present invention, the tip of the shovel is shaped into a notch that shows vertical and inclined shapes, and furthermore, by forming a notch allowance and a serrated shape, it is easy to pierce the solidified waste, and at the same time, crush and soften it. To facilitate these removal operations. Along a shovel edge A of a shovel body H,
A notch C and a notch C3 are formed by shaping the notch C1 indicating a vertical shape and the notch C3 indicating a slant shape. This is the idea of a sword excavator.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a shovel that can be easily pierced into hard ground or the like, and at the same time, crushes and softens, thereby facilitating these digging operations (including moving operations), and performing a simple work setup. .

[0002] Although it is necessary to remove or excavate waste and solids that are hardened unexpectedly using a pickaxe or the like, work preparation is complicated when the number of tools is increased. However, the disposition after work becomes more and more complicated, but it also has the effect of saving those troubles.

[0003]

[Prior art]

 Conventional sword-tip shovels are called sword-tip shovels (scoops), reminiscent of a Western-style blade, because the tip of the shovel is rounded and shows a cutting edge. Although this shovel emits less than a square shovel, it is used as a tool for discharging hardened earth and sand and chipping and removing chips.

[0004]

[Problems to be solved by the invention]

 Although it is a sword-tip shovel used as a tool for discharging hardened earth and sand and removing and breaking chips, it can be hit back on the hardened ground unexpectedly and achieve its purpose. At present, excavation work is performed after chipping using a pickaxe.

[0005] However, as the number of tools increases, the arrangement of work becomes complicated, and the disposition after the work is proportional thereto, which can be a complicated work. Therefore, there is a demand for the development of construction tools that can easily arrange work.

[0006]

Means for Solving the Problems In order to solve the above-mentioned problems, the present inventors focused on a conventional sword-point shovel, and provided a loose-shaped projection, which is a kind of saw tooth, at the tip of the shovel. By forming it, it is easy to pierce the hard ground, etc., and it is chipped and crushed to facilitate excavation work.

[0007] In addition, since some of the projections have a loose shape, they cut off the ground and soften solid objects, thereby improving workability. It is to let.

【Example】

 The present invention will be described with reference to the drawings. FIG. 1 is a partial plan view of the sword excavator according to the present invention, FIG. 2 is an enlarged and partial cross-sectional view taken along the line XX of FIG. 1, and FIG. FIG. 4 is a partially enlarged perspective view of FIG.

[0009] The notch C1 and the notch C3, which are perpendicular to the excavator edge A of the excavator main body H and are inclined at key points of the excavator body H, are shaped to show a notch allowance C and a saw-tooth shape. The projection E is formed.

[0010] By shaving the upper surface of the projection E having the saw-tooth shape and indicating the finishing allowance C5, the tip of the projection is further sharpened. The shovel thus manufactured according to the present invention is used on the basis of the arrow Z indicating the point of movement of the shovel.

The tip of the shovel can be easily pierced into the solidified ground by the notch C1 indicating the vertical direction, the notch C3 indicating the inclined shape, the notch allowance C and the projection E indicating the sawtooth shape, and at the same time, it is crushed. Shows a softening effect.

[0012]

[Effect of the invention]

 In this invention, the excavator tip is cut vertically and inclined, and the notch allowance and serrated projections are formed to make it easier to pierce hard ground and to crush and soften it. To facilitate these digging operations.

[0013] Furthermore, excavation work is performed on a hard solid ground or the like unexpectedly after chipping using a pickaxe or the like. However, when the number of tool stands increases, work setup becomes complicated, and after work the work is complicated. Cleaning up becomes a cumbersome job in proportion to that. Therefore, the development of the shovel according to the present invention can be used for versatile work purposes, so that a simple work setup can be performed.
