U-shaped m inclined at the same angle and in the same direction as helical cutter 2
The helical cutter 2 is disposed within the inclined guide member 6 on one side, and the high-level side end of the inclined guide member B is fixed to the support frame 8, and the tip of the helical cutter 2, that is, the low-level side An end portion of the inclined guide member B protrudes from the tip of the inclined guide member B, and an excavated soil discharge hole 4 is provided at the lower part of the higher level side portion of the inclined guide member B, and a crack opening surrounding the excavated soil discharge hole 4 is provided at the lower part of the excavated soil discharge hole 4. One end of the annular body 5 in the diametrical direction is pivotally attached to the inclined guide member B by a horizontal shaft 25, and the other end of the annular body 5 in the diametrical direction is attached to the inclined guide member 3. When the weight detector 26 detects a predetermined weight, a timer circuit is activated by a signal from the weight detector 26, and the cutter rotation drive device 1 is operated and the turning liquid is activated. The expansion and contraction operation of the pressure cylinder 16 is stopped and the buzzer sounds.

A gear pump 27 driven by the engine of the self-propelled vehicle 7 is mounted on the body 24 of the self-propelled vehicle 7, and the gear pump 27 supplies pressurized fluid to the hydraulic cylinders 11 and 14 through the control valve. hydraulic cylinder 16 and hydraulic motor 17.

FIG. 6 shows the sandbag bag 28, and the bag body 29
A binding string 60 is inserted in a zigzag pattern along the mouth edge of the belt, alternating between the front and back sides.

Next, the operation when constructing sandbags using the sandbag constructing machine of the above embodiment will be explained.

The work is carried out in teams of two people, one of whom rides the self-propelled vehicle 7 and drives the self-propelled vehicle 7 and operates the control pulp of the sandbag making machine, and the other person This person is responsible for attaching and detaching the sandbag to and from the annular body 5 for attaching the cleft opening, and for tying the binding cord 30'.

When constructing a sandbag, first fit the opening of the bag body 29 in the sandbag Tsuyoshi 28 to the outside of the annular body 5 for attaching the tear opening, fasten it to the binding string 3o, and connect the drive for rotating the cutter. While the helical cutter 2 is being rotated by the device 1, the hydraulic cylinder 11.14 for elevation is operated to cut the tip (front end) of the helical cutter 2 into the ground 61 to an appropriate depth, and then for turning. Earth and sand are excavated while the J-niji, helical cutter 2, and inclined guide member 6 are rotated over the range shown by the two-dot chain line in FIG. 2 due to the expansion and contraction operation of the hydraulic cylinder 16.

The excavated earth and sand is transported upward diagonally along the bottom of the inclined guide member 3 by the helical vane 20 of the helical cutter 2, and then passes through the excavated earth discharge hole 4 and the annular body 5 for attaching the bag opening. It is put into the bag body 29.

After turning excavation of a predetermined width is completed, the self-propelled vehicle 7 is driven an appropriate distance to make a cut, and then the helical cutter 2 is turned again to perform excavation.

When the bag body 29 is filled with a predetermined weight of earth and sand, a signal from the weight detector 26 causes a buzzer to sound,
Since the rotation and turning of the helical cutter 2 is stopped for a certain period of time, the bag body 29 filled with earth and sand is removed from the annular body 5 for attaching the cleft opening, and the opening of the bag body 29 is tied with the binding string 60. The bag body 29 is closed and tied up, and then the empty bag body 29 is tied up.
The entire opening of the ring is attached to the annular body 5.

After a predetermined period of time has elapsed, the rotation and turning of the helical cutter 2 is automatically started again.

Note that excavation may be performed while the helical cutter 2 is moved forward by the self-propelled vehicle 7 without turning the helical cutter 2.

When transporting the sandbag making machine, use hydraulic cylinder 1 for elevation.
4, the helical cutter 2 and the inclined guide member 3 are raised and rotated to the position shown by the two-dot chain line in FIG. The helical cutter 2 and the inclined guide member 6 are rotated completely upward to prevent the helical cutter 2 and the inclined guide member 6 from colliding with the protruding part of the ground.

〔Effect of the invention〕

According to this invention, the earth and sand excavated by the helical cutter 2 rotated by the cutter rotation drive device 1 is moved diagonally upward along the bottom of the inclined guide member 6 by the helical vane 20 of the helical cutter 2. Let me,
It is possible to automatically charge and fill the sandbag rigid 28 attached to the annular body 5 for attaching the fissure opening, so that sandbags can be created in large quantities with high efficiency by using all the mechanical power with a small number of workers. The self-propelled vehicle 7 can easily and quickly move the sandbag making machine to any desired location, and the self-propelled vehicle 7 can easily cut and move the helical cutter 2 at the excavation site. Effects such as being able to do this can be obtained.
