Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is intended to automatically penetrate an inverted U-shaped film support pillar, which is the support pillar, into the soil when a multi-film is stretched in a tunnel shape. The purpose of the present invention is to provide a film column driving device devised so that the driving can be carried out at intervals of.

[0002]

2. Description of the Related Art Conventionally, an inverted U-shaped film strut used in a so-called tunnel multi is conventionally driven by hand, so that the film strut is transported and arranged at a predetermined interval, and then, one film is strung. At present, it takes a lot of labor and a long working time to drive the film column while supporting it by hand.

Further, as a publicly known document, SAIKAI Sho 59-10
There is one described in Japanese Patent No. 1644, but this one is one in which the film strut is pushed backward by a pressing lot of a hydraulic cylinder in a supply section accommodating the film strut and dropped into the slit. The columns are designed to be driven into the soil with a lot of hydraulic cylinders on the left and right, and the film column is well embedded in the soil because the driving part of the film column is located far from the operator. It is difficult to confirm whether it has been driven.

[0004]

DISCLOSURE OF INVENTION Problems to be Solved by the Invention The present invention automates the operations such as manual transportation, placement, and driving so that the driving of the film column can be surely performed with a small labor and a short working time. It is intended to make sure that the film pillar is driven into the soil while devising it.

[0005]

The present invention has been proposed in view of the above-mentioned problems, and has taken the following technical means. That is, a plurality of inverted U-shaped film columns 6, a column holder 5 holding these film columns 6, and a film column 6 taken out from the column holder 5.
A column feeding device 7 for transferring the column toward the column penetrating device 8,
A film column striking device having a column column penetrating device 8 provided so that the film columns 6 received from the column column feeder 7 can penetrate into the soil at a predetermined interval. The film strut driving device is characterized in that it is provided at a side position.

[0006]

Function: The inverted U-shaped film column 6 is provided with the column feed device 7
Is sent to the side of the pillar penetrating device 8 closer to the towing vehicle,
The film column 6 is pressed from above by the column penetrating device 8 and driven into the soil as it is.

Embodiments of the present invention will be described below with reference to the drawings. First, the configuration will be described. As shown in a side view in FIG. 1, a side view L-shape is connected to a tractor 1 via a working machine connecting link mechanism 2 by a lift cylinder 3 of a hydraulic lifting mechanism so as to be able to move up and down. A column holder 5 is provided at the rear part of the frame 4, and the mountain-shaped upper part of the film column 6 is formed so that a plurality of inverted U-shaped film columns 6 straddle the column holder 5 in a front view. The support 5 is supported by the bottom portion 5a of the holder 5, and the film support 6 is provided in front of the support holder 5.
A column feed device 7 for moving the frame 4 forward is provided above the horizontal frame portion 4b of the frame 4, and a vertical frame of the frame 4 is provided.
The film strut 6 is provided on the shutter 9 of the strut penetrating device 8 provided in the film portion 4a so as to be fed from the strut feeding device 7.
The film support 6 on the shutter 9 is moved to a predetermined depth in the soil by the operation of the support penetrating device 8 so that the left and right leg portions 6a, 6a are formed.
It is configured to be driven in until it is penetrated.

The strut feeding device 7 in this embodiment is a belt conveyor 11 with a lug which is mounted so as to straddle the film strut 6, and a model which is controlled so as to intermittently rotate the belt conveyor 11 to the front side. The film strut 6 discharged from the turning end of the belt conveyor 11 is guided downward by the shoot 13 provided on the frame 4 and falls obliquely downward. As a result, the left and right leg portions 6a, 6a of the film strut 6 are fitted into the hopper-shaped guides 14, and are held in a substantially upright position right below the strut penetrating device 8 while the film is formed on the shutter 9. The shutter 9 is provided so that the upper portion of the column 6 can be mounted thereon, and the shutter 9 is pivotally attached to the shoe 13 by a pin 15 and is held by a spring 16 in a substantially horizontal receiving posture.

The strut penetrating device 8 is located directly above the hydraulic cylinder 17 provided on the vertical frame portion 4a and the upper part of the film strut 6 on the shutter 9 in the retracted position, and as shown in FIG. It is composed of a piston 18 capable of penetrating the film strut 6 into the soil at the height shown on the right side, and the tip end of the piston 18 can be fitted onto the mountain-shaped upper portion of the film strut 6 with little play and is in a front view. A column holding member 20 having a mountain-shaped fitting groove 19 is provided.

The above-mentioned strut driving device has a structure in which the multi-film 21 can be stretched on the upper part of the film at the same time, and the multi-film is pulled out from the film roll 22 rotatably supported at the rear part of the frame 4. Attach the film 21 to the upper surface of the film guide 23 and the mountain-shaped film guide 24.
So that the left and right side portions of the mulch film 21 are trampled by the weights and the springs 25 by the left and right compression wheels 26, 26, while the left and right soil cover bodies 27, 27 cover the left and right side portions. I am configuring.

In the above embodiment, when the tractor 1 is stopped, the strut penetrating device 8 and the strut feeding device 7 are automatically operated in conjunction with the stop operation. 3 shows a control circuit diagram, and FIG. 4 shows a hydraulic circuit diagram. One of the stop operation, depresses the clutch pedal 28, the switch L ₃ which detects a depression operation is turned on, the normally-open contact L ₃ a is closed.

At this time, the film support on the shutter 9 is

Then, the film column 6 clamped by the column clamp 20 starts to penetrate into the ground. When the film column 6 is penetrated to a predetermined depth, the switch L ₄ is turned off and the relay R is also turned off. As a result, the extension solenoid sol ₁ is demagnetized and the projecting operation of the piston 18 is stopped. Further, the normally closed contact L ₄ b of the switch L ₄ is closed, and the normally closed contact L ₁ b of the switch L ₁ is also closed.
The relay R ₂ will be activated again.

Becomes

When the driving of one film support column 6 is completed in this way, the tractor 1 is advanced by a predetermined distance and the film support column 6 is driven again. In order to transfer the film supporting column 6 on the supporting column holder 5 to the supporting column feeding device 7, it is manually carried out by an assistant riding on step 32 provided in the L-shaped frame 4 in the illustrated example. However, this can also be automated by the operation of appropriate cylinders and pistons.

Although not shown in the drawings, the column penetrating device 8 may be configured so as to be driven by a hammer, and the column holder 5 and the column feeding device 7 may be other than those shown in the figures.
Various ones can be used.
