JPH0643247Y2 - Digging trench excavating compactor - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a compacting machine capable of simultaneously performing both compaction of the ground and excavation of a trench for digging for drainage in construction and construction work. .

[Prior art] When excavating a ditches for drainage for the purpose of slope protection, road drainage, etc. in construction work, etc., use a compacting machine in advance so that the trench does not collapse during excavation. Compact the ground,
After that, excavation of the ditch is carried out manually or using a cultivator or a tractor.

[Problems to be solved by the invention] In the processes in which the compaction and the excavation are different from each other as described above, the work efficiency is low, the number of days is required, and the labor cost and the fuel cost are increased. There was a problem.

Furthermore, there is a problem in construction management that the ground around the trench is loosened by excavating the trench.

The present invention has been conceived to solve the above-mentioned conventional problems, and an object thereof is to provide a new trench excavating compactor capable of continuously performing both compaction and excavation simultaneously. To do.

[Means for Solving the Problem] The invention based on the above-mentioned object is provided in the center of the rear part of the vibration compactor so that the excavation of the trench can be performed following the compaction of the ground.
It has a V-shaped cross section and is equipped with an excavating blade at the tip, and a rear end is bent upward to the side to attach a groove excavator formed at the soil discharge port so that it can be moved up and down, thereby solving the conventional problems. is there.

[Operation] In the above-mentioned configuration, the vibration compactor works as a compaction of the ground and the power source of the groove excavator, and the groove excavator bites into the ground due to the weight and vibration of the vibration compactor, and the vibration compactor The trench is excavated by advancing with it.

[Embodiment] In the drawings, 1 is an oscillating compactor having a normal structure, and 2 is a groove excavator attached to the rear center of the oscillating compactor 1.

As shown in FIG. 2 and FIG. 4, the groove excavator 2 has a V-shaped cross section and a lateral shape in which the tip 2a is inclined forward, and the opening edge of the tip 2a is excavated. It is formed on the blade. Further, the rear end 2b is formed to be bent to the upper side and serves as an earth discharging port that is opened to the side of the front end 2a.

Pressing plates 3 are attached to both side surfaces of the front part of the groove cutting tool 2. A pair of support legs 5 fixed to the lower side of the horizontal member 4 are coupled to the holding plate 3, and arm plates 6 for connection are provided at both ends of the horizontal member 4, and the vibration compactor is provided at the center. A pair of connecting plates 8 connected to the operating rod 7 provided at the rear portion of the unit 1 are integrally provided with members 9 welded to the transverse members.

The connecting plate 8 is formed by an arc-shaped curved plate centered on the shaft attachment portion 6a at the tip of the arm plate 6, and a plurality of mounting holes 8a, 8b are formed on the plate surface at predetermined intervals. It is set up.

As shown in the figure, such a groove excavator 2 has the arm plate 6 described above.
Of the vibration rod compactor 1 are placed on both sides of the rear part of the vibratory compactor 1, and the shaft-attaching part 6a is rotatably fixed to the compactor by a connecting pin. By fitting a pin into any one of the mounting holes 8a and 8b and connecting it to the operating rod 7, the vibration roller 1 can be mounted in the center of the rear part like a plow.

When the operation rod is connected to the upper mounting hole 8a for mounting the groove excavator 2, as shown by the solid line in FIG.
The ground is excavated horizontally, but the lower mounting hole 8b
When it is connected to, the whole body pivots upward with the shaft attachment portion 6a of the arm plate 6 as a fulcrum, and is positioned obliquely higher than the ground as shown by the chain line. Therefore, only the ground compaction can be performed.

In the vibration compactor 1, the ground is compacted by the roller 10 as usual.

Next, the groove excavator 2 receives the weight and vibration of the vibration compactor 1,
As it begins to bite into the ground from the tip, the groove 11 is excavated following the rolling of the ground by the roller 10. Then, the excavated soil is pushed backward in the trench excavator, and is sequentially discharged to the ground from the soil discharge port at the rear end 2b opening to the outside of the trench 11.

[Effect of the Invention] As described above, the present invention connects the groove excavator 2 like a plow at the center of the rear part of the vibration compactor 1, and uses one vibration compactor to perform both compaction and excavation of the ground. Since it can be performed continuously and simultaneously, there is no need to perform both of them in separate processes as in the past, and there is no need for equipment such as a cultivator or a tractor for different work purposes, which wastes time in the process. No longer required, the number of construction days will be shortened, and labor and cost will be significantly reduced.

In addition, the structure is simple and there is no failure, only special operation is required just by operating the vibration compactor.If only compaction is required, the groove excavator is rotated to pull it up above the ground and fix it. Since it only needs to be placed, it does not need to be removed one by one when it is not needed, and it has many useful features such as the problem of construction management such as loosening the ground after compaction due to trench excavation and the problem of construction management.
