DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for burying a self-supporting material having corrosive properties such as straw in a sandy area such as a desert.

[0002]

2. Description of the Related Art In recent years, attempts have been made in China and the like to bury straw in a grid in a desert. The purpose of burying straw in a lattice is to divide the surface of the desert into a lattice to prevent the sand from scattering due to wind, etc., to grow plants that are strong in the sand in the lattice and to make the desert green. is there. Conventionally, in order to bury straw in a lattice in a desert, a method of manually digging a lattice hole in the desert and putting straw into the hole has been adopted.

[0003]

However, when straw is buried in the desert manually as in the prior art, the work of burying the straw takes time and the area of the desert to be greened is wide, so that the labor is hampered. , And the labor cost increases. In addition, the speed of manually laying straw is slow, and there is a possibility that the area to be greened cannot catch up with the area to be desertified.

[0004] It is an object of the present invention to provide an apparatus for burying a self-supporting material which can embed a self-supporting material such as straw easily, quickly and inexpensively.

[0005]

Next, the operation of this embodiment will be described. FIG.
Is a diagram for explaining the flow of the operation of the embedding device SD of the present embodiment. The embedded device SD travels in a zigzag shape along the direction of the arrow in FIG. 8 and stops when it travels the length of the suction cylinders 31a to 31c extending in the front-rear direction of the device SD,
Work of hole formation → straw drop → straw burial, which will be described later, is performed.

Prior to the straw burying operation performed by the burying device SD, an operation of supplying straw to the dropping device 4 is performed by the supply device 5. First, the motor 53 of the supply device 5 is driven, and the straw in the pallet 2 is
And the straw is inserted between the pins 56. Next, the belt 58 and the pin 56 are rotated by the motor 58 in the direction indicated by the arrow B in FIG. At this time, the straw inserted between the pins 56 moves with the movement of the pins 56 while being held between the pins 56 unless an external force acts.

Next, when the actuator 60a causes the blocking plate 61d located at the uppermost stream in the rotation direction of the belt 55 (located at the lowermost end in FIG. 6) to protrude above the transfer mechanism 54, the straw is transferred to the blocking plate 61d. The rotation movement along the belt 55 is restricted by the contact, and only the straw separates from the pin 56. In this state, if the straw pushing by the pushing plate 51 and the rotation of the straw by the belt 55 are continued, the blocking plate 61 d
The straw in the vicinity is pushed by the straw on the rear side, advances in the guide path 59d, and heads above the drop control shutter 41d. This behavior is
The operation is continued until the guide path 59d is filled with straw, and when the straw is full and the load applied to the belt 55 is increased, this is detected and the blocking plate 61d is retracted from above the transfer mechanism 54, and the next step is performed. The blocking plate 61a is projected above the transfer mechanism 54. By repeating the above operation, all the guide paths 59a to 59a
9d is filled with straw.

When the burying device SD moves to a predetermined position in the desert where straw is to be buried, the moving operation by the crawler device 1 is stopped and hole formation → straw drop → straw burying operation is performed in order.
In the present embodiment, the hole forming operation is performed by two of the suction cylinders 31d extending in the left-right direction of the apparatus SD and the three suction cylinders 31a to 31c extending in the front-rear direction. The suction cylinder 31 of the present embodiment is not used. First, in the first step shown by the arrow A in FIG. 8, only the suction tubes 31a and 31b are used, and the suction tube 31c is not used.

The hole forming operation is performed by the cylinders 32a, 32b,
It starts by lowering the suction cylinders 31a, 31b, 31d by 32d. Next, the suction cylinders 31a, 31
b, when the lower end of 31d touches the sand surface, blower 34a,
The operation of the suction cylinders 31a, 31d is started.
b, the sand in the 31d is sucked into the suction pipes 33a, 33b, 3
Suction from 3d, discharge pipes 35a, 35b, 35d
To be discharged. Then, the cylinder 32a to a predetermined depth,
When the sand discharge operation by the blowers 34a, 34b, 34d is stopped in a state where the sand 32b, 32d is lowered and the sand in the inside is almost discharged, the cross-sectional shape becomes the suction cylinder 31a, 31b, 3,
An F-shaped hole approximately equal to 1d is formed near the surface of the desert.

At the stage when the hole is formed by the suction device 3,
Dropping device 4 corresponding to each suction cylinder 31a, 31b, 31d
When the drop control shutters 41a, 41b, and 41d are opened by the cylinders 42a, 42b, and 42d, the straw above the drop control shutters 41a, 41b, and 41d passes through the through holes 43a, 43b, and 43d of the drop device main body 40 and the suction cylinder. It falls toward 31a, 31b, 31d. Then, contrary to the case where holes are formed, the blowers 34a and 34
b, 34d, the desert sand is sucked from the distal ends of the discharge pipes 35a, 35b, 35d, and the suction pipes 33a, 33
Return to the inside of the suction cylinders 31a, 31b, 31d via b, 33d. The sand is filled in the gap between the suction cylinders 31a, 31b, 31d and the straw, and the straw is fixed to the desert ground surface. Thereafter, the suction cylinder 31 is operated by the cylinders 32a, 32b and 32d.
a, 31b, 31d are raised, and these suction cylinders 31a,
When the straws 31b and 31d are removed from the desert, the straw SR indicated by a in FIG. 8 can be buried in the desert.

Then, the crawler device 1 uses the embedding device S
D is moved by the length of the suction cylinders 31a to 31c extending in the front-rear direction of D, and the above-described hole formation → straw drop → straw burying work is performed to bury the straw SR in the portions indicated by A to F in FIG. can do. Finally, just before the change of direction (part shown by G in FIG. 8)
In the step, the suction cylinder 31 extending in the left-right direction of the device SD is provided.
The burial operation is performed using only the straw.

Next, the whole embedding device SD is turned by the crawler device 1 and the next step shown by the arrow B is started. Then, the suction tube 31b is turned on the other hand in the process shown by the arrow B after the turn. , 31c and a suction cylinder 31d, the straw burying work is performed without using the suction cylinder 31a. In this way, the straw SR in the portion indicated by the letter 〜 in FIG.
Can be buried in the desert. Thereafter, if the above operation is repeated while moving by a predetermined distance, the straw SR can be buried in a lattice shape on the desert ground surface.

Therefore, according to the present embodiment, it is possible to mechanize the work of burying straw in the desert, to save labor costs and reduce costs, and to increase the working speed. Burying work can be performed quickly.

The details of the self-supporting material embedding device of the present invention are not limited to the above-described embodiment, and various modifications are possible. As an example, the material to be buried in the desert is not limited to straw, and may be any free-standing material having corrosive properties such as wood. The zone to which the present invention is applied is not limited to a desert, and can be widely applied to a sandy zone such as a dune or a coastal sand.
