Abstract

PROBLEM TO BE SOLVED: To provide an earth removing plate of a construction machine to replace a conventional earth removing plate having a linear form when seen from directly above, the conventional earth removing plate being pushed forward and causing leakage of sediment from right and left edges of the earth removing plate, when the sediment piles up in front of the earth removing plate.SOLUTION: An earth removing plate has a circular arc form when seen from directly above. The earth removing plate causes sediment to pile up at a center when the sediment is pushed forward, reducing an amount of sediment leaking from right and left sides of the earth removal plate and eliminating a need to push out the sediment repeatedly. Thus, back-filling and ground leveling work may be performed efficiently in a short period of time.SELECTED DRAWING: Figure 2

Description

  The present invention relates to a soil discharging board of a construction machine for extruding earth and sand.

  There is a thing which has an earth excavation board which extrudes earth and sand in the advancing direction of construction machines, such as a hydraulic excavator, a bulldozer, a wheel loader, and a motor grader. Usually, the shape of the earth removal board is straight when viewed from directly above. Some of them deform into a V shape.

  Japanese Utility Model Publication No. 61-076861

  Since the conventional earth discharging board described above spills from the left and right ends when the earth and sand are pushed out, the leveling work has been carried out while pushing out the place once pushed once and once and right and three times or more in total. In some cases, the main body of the dumping board tilts (angle), but either the left or right does not spill but the opposite side spills, so the spilled earth and sand were pushed out once more.

  In addition, since the object deformed into a V shape increases in the number of parts and becomes heavy and fragile, it is in a wheel loader for snow removal, but there are only a few construction machines for pushing out earth and sand in a large bulldozer.

  An object of the present invention is to solve the problem of such a conventional earth discharge plate shape, and to efficiently perform earth and sand backfill leveling in a short time.

  In order to solve the above problems, the present invention is such that the shape of the earth discharging plate is formed in an arc shape so that earth and sand accumulate in the traveling direction when viewed from directly above.

  As described above, the shape of the earth discharge plate of the present invention accumulates in the middle when the earth and sand are pushed out. If earth and sand accumulates in front of the soil removal board, if the height of the soil removal board is raised, it will not spill from side to side. Especially in narrow places, there is no worry of leveling spilled earth and sand manually.

  In addition, even in the soil leveling work with a small amount of earth and sand, it does not spill to the left and right, so that the height of the leveling surface can be easily obtained efficiently, and it is simple and not broken compared to a material deformed into a V shape.

The figure which shows the whole structure of the figure which shows the hydraulic shovel by embodiment of this invention. The top view which looked at the earth removal board of this invention from right above. The perspective view which looked at the earth removal board of this invention from the left front. The top view which looked at the embodiment of the present invention from right above. The top view which looked at the conventional earth removal board work from right above.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  In the figure, 1 is a soil discharge plate, 2 is a link and 4 hydraulic excavator bodies are connected.

  The operation of the above configuration will be described below with reference to FIG. The earth and sand 5 are pushed forward by the earth discharging board 1. The earth and sand 5 collects in the middle of the earth discharging board 1. Sediment 5 is less likely to spill from the left and right sides of the soil discharge board 1. If the amount of the earth and sand 5 increases, the earth and sand 5 will not spill if the height of the earth and sand board 1 is adjusted and pushed out, so that the earth and sand 5 accumulated on the earth and sand board 1 can be easily moved. .

  Further, in the soil leveling work in a narrow place, the conventional soil discharge plate of FIG. 5 zeros the earth and sand to the left and right, so it is necessary to level the earth and sand again manually or with a bucket of a hydraulic excavator. there were. Since the earth discharge plate of the present invention does not spill, it can be efficiently operated in a short time.

  Further, even when a small amount of earth and sand is leveled, the earth and sand do not spill to the left and right, so that the leveling level can be easily finely adjusted, so that the work can be performed smoothly and easily.

  Although one embodiment of the present invention has been described so far, the present invention is not limited to the above-described embodiment, and it is needless to say that the present invention may be implemented in various forms within the scope of the technical idea.
