BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to strut driving having a shape-restoring property when a vinyl film or the like is stretched in a tunnel shape by aligning the strut arbitrarily inserted into the strut hopper on one surface. 1 pay out one by this device, and Repetitive issued was allowed to bent in an inverted U-shape in accordance with the different ridge widths for crops strut relates <br/> to hit writes tunnel multi post implantation device into the soil.

[0002]

2. Description of the Related Art In a conventional strut driving device, for example, a single propelling device for a strut formed by bending a pipe made of iron or aluminum into a certain inverted U shape is a saddle-shaped support rack. Struts are lined up in a row, and springs, weights, and chain conveyor are used to pressurize them, and
The props of the book are fed out by a hydraulic cylinder or the like, and are supplied and driven into an inverted U-shaped driving frame that moves up and down along the upper and lower rails. In addition, regarding the tunnel multi-struts having shape restoration, one strut is drawn out from the hopper having a narrow structure so that one strut is supplied to the bottom, and the same inverted U-shaped driving frame and strut as above. It was installed by a structure in which both ends of the above are pressed and held from the side.

[0003]

[Problems to be Solved by the Invention] In the method of driving a support column formed in an inverted U shape, the support column to be used is thick and heavy.
The number of columns that can be set in the driving device at one time cannot be increased, and the driving width cannot be changed when the ridge width for crop cultivation is different. In addition, it is necessary to arrange the columns one by one when the column is stretched into the column hopper and the like, and it is also necessary to release the pressure applied by the spring and the like. Further, in the method of driving the driving frame with the hydraulic cylinder, there is a problem that the shape of the inverted U-shaped support is easily deformed by the driving frame and the driving accuracy is lowered.

When the support column having a shape restoring property is fed, if the support column is arbitrarily inserted into the hopper, since the support column is long with respect to the wire diameter, the support columns are entangled with each other without being aligned, and it is difficult to smoothly feed the support column. In the driving method, both end portions of the pressing and post by implantation frame there is a method that Soo pressing <br/> coercive in ridge inwardly from the side, until the end of the driving under the influence of restoring repulsive force of the strut There is a problem that it is difficult to secure the driving accuracy because it cannot be pressed and held from the side.

All of these tunnel multi-pillar driving devices are mounted on a low-floor traveling trolley or the like and utilize a driving frame that moves up and down, and when it is desired to pass over a crop having a high plant height or an existing strut, a ridge is required. We couldn't handle it if the width was different and we wanted to change the driving width.

In order to solve the above problems, in the strut driving device of the present invention, since the strut having the shape restoring property is used, the strut is grasped and curved in an inverted U shape, and both ends of the strut are perpendicular to the ridge surface. It is driven into the soil. This removes the restoring repulsive force of the column in both leg portions below the grip portion, and effectively applies the striking pressure of the column. Furthermore, in order to adapt the striking width of the support columns to different ridge widths for crop cultivation, it is desirable that the striking portion is divided into left and right portions, and the interval between the left and right striking portions can be adjusted.

Further, a method of gripping and curving both ends of a column having a shape restoring property uses a pair of left and right rollers which rotate outwardly with respect to each other, and the column is made perpendicular to the ridge surface by setting the angle of the outward rotation. There is a configuration to do. Further, in order to adapt to different ridge widths for crop cultivation, it is preferable that the left and right gripping bending rollers can be adjusted. Furthermore, in order to improve the workability in the field by supporting a wider range of ridge width and allowing passage through existing stanchions, this driving part should be a stilt type running part that can adjust the wheel distance. It should be installed.

Further , in order to automatically feed out the columns having a shape restoring property which is long with respect to the wire diameter one by one from the hopper,
It is necessary to align the columns that are thrown in arbitrarily in one row.
To this end, it is important to remove the extra gap between the props that have been thrown in, so that the props that flow down in the hopper are given a descending order so that one prop can be fed into the passage. Is desirable.

Further, falling to To remove the gap between posts that are submitted to arbitrarily hopper well give vibration to the post, Komu sent to passageway capable of passing through one strut gives an order to flow down the pillars It is advisable to use a notch plate that rotates in the opposite direction.

Further, in the method of gripping and bending both ends of the support pillar and continuously driving it into the soil, it is necessary to take a measure for promoting separation of the gripping curved portion from the support pillar at the end of driving. For this purpose, it is advisable to press the upper end of the curved strut at the end of the driving to spread both legs of the strut outward in the ridge, and to secure the separation gap of the grip portion.

In the present invention, reflecting the above,
Restoration of props Effectively create striking pressure for props, excluding repulsive force
It is possible to drive while ensuring the precision of driving.
In addition, it corresponds to the ridge width and passes through the existing columns
In addition, the stanchions can be automatically and accurately one by one from the hopper.

There is 4. The strut aligning plate 14 can be adjusted in the vertical direction by the set screw portion of the pillow block 13a according to the cross-sectional diameter of the strut S that uses the distance from the bottom of the hopper.

At the bottom of the column hopper H, there are 15 below the pushing lots 15 for feeding columns one by one.
There is an eccentric cam 16 for vertically moving, and an eccentric cam shaft drive pin 19 fixed coaxially with 16. The pushing lot 15 is pressed downward by a spring 15a and is in contact with the end surface of the eccentric cam 16 by a bearing 15b at the lower end of the pushing lot 15. The eccentric cam 16 receives a rotational force from the spring 17, and is positioned so as to block the support column flowing down from the pushing lot 15 except when the support column P is being fed. The shape of the lower end of the pillar alignment plate 14 is the pillar P drawn by the pushing lot 15.
Are formed so that they are properly discharged to the strut driving portion R.

In FIG. 2, at the lower part of the driving frame 23, there is a hook 18 for applying a rotational force to the eccentric cam shaft drive pin 19 in the prop feeding portion of the hopper H, and the eccentric cam shaft drive when the driving frame 23 is raised. The pin 19 is pushed up and pushed up, the eccentric cam 16 rotates, pushes up the pushing lot 15 upward, and pays out the support column.

In FIG. 3, the side surface portion 38 of the column hopper H is shown.
Since it corresponds to the wheel distance adjustment of the traveling carriage S and the ridges for crop cultivation of different widths, it is possible to adjust the expansion and contraction in the left-right direction. Further, one side plate 35 can be opened and closed to serve as a loading port for the pillar P. Further, there are strut guides 35a at the lower portions of the left and right side plates 35, which regulate the discharge direction of the strut that is fed out from the hopper H, and the shape of 35a is such that the end surface of the strut P during curving and descending by the strut driving part R is It is formed so as to contact and guide.

The driving portion supporting frame 1a has a roller chain 43a for winding the driving frame 23, a slopcket 43, and a winding shaft 10, and the other end of 43a is a weight 4a.
It is connected to 2. Further, the driving frame 23 is prevented from falling by a piston type support pin 24 driven by a direct current motor (not shown).
3 is suspended and fixed to the driving part supporting lateral frame 1b so that the driving width of the support pillar P can be adjusted according to the width of the ridge for crop cultivation.

In the strut driving portion R, a pair of rollers 11, 11 for holding and bending the driving portion supporting frame 1a, the driving frames 23, 23 for guiding the vertical movement of the driving frames 23, 23, the driving rail 20, and the supporting pillar P. To the gears 27, 28, 27 that transmit the rotational force to
At the other ends of 6 and 26, there is a support rod 25a that supports the guide roller 25 that contacts the roller guide 21. Also, the support rod 2
The support rod 25a and the arm 2 are attached to the connecting shaft of the arm 5a and the arm 5a.
There is a torsion coil spring 25b that initializes the positional relationship of 6.

The rotation of the support rod 25a on the arm 26 is limited to the upward rotation by a stopper (not shown). While the driving frame 23 is descending, the lower part of the guide roller 25 contacts the roller guide 21 and the support rod 25a rotates. When the rotation of 25a is stopped by the stopper, the rotational force is transmitted to the gripping bending roller 11 via the gears 27 and 28. On the other hand, during the descending end part of the driving frame 23 and during the ascent, the guide roller 2
The upper part of 5 is in contact with the roller guide 21 and the supporting rod 25a is rotated downward, so that the rotational force to the gripping bending roller 11 is blocked.

The rollers 11b and 11c, each having a pair of grooves for gripping and bending the support P, rotate about their centers,
It is fixed on the shaft of the gear 28 by the roller support stay 11a. Also, the torsion coil spring 2 is attached to the shaft of the gear 27.

That is, when the support P fed from the hopper H is received between the roller 11b at the lower position and the roller 11c at the upper position of the gripping bending roller 11 having a concave circumferential surface, the positional relationship between the roller 11b and the roller 11c is changed. initialize.

In FIG. 4, the left and right support driving frames 23 are connected by a connecting rod 31 whose width can be adjusted at the center by a well-known turnbuckle (not shown), and the upper part thereof is inverted U-shaped by the support grip bending roller 11. There are support rods 41 for the column push plates 30 and 30 that hold the upper and left ends of the column P bent downward to below, and the column push plate 30 sets the vertical position and angle according to the driving depth of the column P and the degree of bending of the column. Can be adjusted. The side cross section of the strut push plate 30 has an inverted L shape, the working direction side of the traveling carriage S is a vertical surface, and the strut P is being driven.

On the rear side of the driving rail 20 and on the side surface of the traveling carriage frame 1, there is an arm 21a for driving a direct current motor 21b which makes a reciprocating circular arc motion in the vertical direction so as to forcibly push down the upper surface of the driving frame 23. When the driving frame 23 descends through the rail 20, it assists the action of the roller 11 that tends to bend the pillar P when grasping.

The lower position of the gripping bending roller 11 is caused by the action of the hook 18, the eccentric cam shaft drive pin 19, the eccentric cam 16 and the pushing lot 15 of the driving frame 23 which is aligned and raised by the plate 13 and the column pushing plate 14. Laura 1
It is fed to 1c.

When it is confirmed by a known non-contact sensor (not shown) that the support post P is received by the lower position roller 11c, the support of the driving frame support pin 24 is released and the driving frame 23 begins to descend. When the guide roller 25 in contact with the roller guide 21 comes into contact with the convex portion of 21, the support rod of 25 and the arm 26 rotate about the axis of the gear 27, and the gear 2
A rotation force in the ridge outer direction centering on the shaft of the gear 28 is transmitted to the holding and bending roller 11 via 8 to hold and bend the column. Further, when the driving frame 23 descends, the lowering assisting arm 21a pushes the upper end of the driving frame 23 downward to assist the lowering of the frame 23, and the column P becomes an inverted U shape, and both ends of the column P are made vertical.

During the course of the curving of the column, the roller 1
The two rollers 11b and 11c of No. 1 rotate on their own axis, and the support pillar slides upward, but the support pressing plate 30 prevents the support pillar from sliding, and the gripping curving roller 11 moves so that both ends of the support pillar are perpendicular to the ridge surface. With further rotation, the column is completely gripped. In addition, when the support pillar is curved by the roller 11,
The center of curvature of the column is held by the column guide 35a.

As the supporting pillar P is curved by the gripping bending roller 11, the upper end of the supporting pillar P is supported in the groove of the supporting pillar pressing plate 30.
The pillar P is driven into the soil. Immediately before the end of driving, the gripping bending roller 11 releases the gripping bending force of the support P by the guide roller 25 reaching the recessed portion under the roller guide 21. Further, the driving frame 23 descends until it reaches the lower end of the driving rail 20, the strut pushing plate 30 drives the strut P into the soil, and spreads the legs of the inverted U-shaped strut P toward the outside of the ridge. It facilitates the gripping and bending roller 11 moving away from the existing post.

When the driving frame 23 reaches the lower end of the driving rail 20, a known proximity switch (not shown) confirms the completion of the descent of the driving frame 23, and the electromagnetic clutch 6 is actuated to drive the traveling carriage S. At the same time, the electromagnetic clutch 9 is also actuated to raise the driving frame 23 through the hoisting chain 43a. A known proximity switch (not shown) is provided on the hoisting chain 43a. The hoisting end of the driving frame 23 and the driving frame 2 by the support pin 24 are provided.
After confirming the suspension of No. 3, the electromagnetic clutch 6 is stopped and the driving of the next column is started.

On the other hand, when a known proximity switch (not shown) confirms that the frame 23 has been lowered, the electromagnetic clutch 6
Operates until the encoder 34 provided on the traveling shaft 8 counts the set rotational speed of the traveling shaft 8. That is, the traveling carriage S travels at an arbitrary set distance between the existing support pillar and the next support pillar. As a whole, the traveling carriage S automatically travels and stops intermittently while maintaining a uniform width and interval. The strut P will be driven at a depth.
