Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for removing harmful bamboo trees, and more particularly to grasping and cutting straight stems of bamboo, cedar, cypress and the like, and crushing the cut pieces to effectively use the crushed material. Use it.

[0002]

2. Description of the Related Art Because bamboo has a very strong growth potential, its rhizomes often invade places where it should not grow, causing bamboo pollution that suddenly extends from the unexpected places to the ground.
This is manually cut and removed.

[0003]

[Problems to be Solved by the Invention] Today, there is a shortage of young forest workers, and elderly people cut down harmful bamboo trees growing in places where they should not grow by hand and carry them out of the field to grinders. The work of dumping and treating such waste is severe, and the cutting of bamboo trees growing on slopes is particularly dangerous.

[0004]

A clamp lever for gripping at least two bamboo trees above and below a vertically long frame body attached to the end of a boom of an excavator for excavating and tilting civil engineering, and A compression feeder equipped with a compression roll and a delivery roll that splits and flattens by pressing, and a crusher that crushes the fed flat bamboo, transports it while holding it to the crusher. A cutter that cuts the bamboo tree trunk that is attached and gripped on the bamboo tree, and a compression delivery machine that has a compression roll and a delivery roll that pulls in and presses and presses the piece of bamboo wood cut by the cutter, splits it, and flattens it. It is an object of the present invention to provide a device which comprises a crusher for crushing flat bamboo pieces, and which can easily cut harmful bamboo and work safely.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a partially cutaway side view showing a use state of the present invention. By connecting the brackets 3, 3 projecting in two rows with the links 4, 4, and connecting the piston rod of the hydraulic cylinder 5 to one of the brackets 3, the frame body 2 can be moved by the expansion and contraction and tilting of the boom 1. It is also possible to move in such a direction.

At least two front-open boxes 6, 6 are attached to the upper and lower parts of the frame body 2, and a cutter 8 for cutting bamboo trees 7 is attached to the lower end of the frame body 2.

[0007] Clamp levers 9a and 9b for holding the bamboo tree 7
As shown in FIGS. 2 and 3, the gear shafts 10a and 10b are provided with a pair of upper and lower bases provided in the box 6 in parallel in the vertical direction. The shaft end of one of the gear shafts 10a is projected from the box 6, the driving gear 11 is fixed to the upper projecting end, and the planetary gear 12 is fixed to the lower projecting end.

A rack 14 is provided on the side of the piston rod of the hydraulic cylinder 13 mounted on the upper surface of the box 6 and meshes with the driving gear 11, and the driving gear 11 is moved by the reciprocation of the piston rod.
Is rotated forward and backward.

The other gear shaft 10 b projects downward from the box 6, and the driven gear 1 meshes with the planetary gear 12 at the shaft end.
5 and the driving lever 11 is rotated in the forward and reverse directions to rotate the clamp lever 9.
a and 9b approach and separate from each other, and grasp the bamboo tree 7 when approaching.

According to a second aspect of the present invention, the cutter 8 is connected to the
As shown in the figure, the bases of the pair of cutter pieces 8a, 8a are attached to the tip of the piston rod of the hydraulic cylinder 17 so that the cutting edge expands and contracts about the shaft 16, and the hydraulic cylinder 17
Is fixed to the lower end of the frame body using the attachment member 18, and the bamboo tree 7 gripped by the clamp levers 9a and 9b is cut.

A movable compression roll 19a whose roll axis swings right and left and a fixed compression roll 19b fixed at a fixed position where the movable compression roll 19a moves and makes surface contact are provided below the cutter 8. A pair of delivery rolls 21 are provided near the upper opening of the hopper 20, and a pair of delivery rolls 21 are provided near the lower opening of the hopper 20, and a compression delivery device 23 for the bamboo tree 7 provided with a guide member 22 at the center of the hopper 20.

The compressed bamboo pieces are sent to a crusher 25 provided with a circular cutter 24 to crush the bamboo trees 7. Incidentally, a bucket for accommodating the crushed pieces is placed below the crusher 25 as necessary.

[0013]

According to the present invention, the harmful bamboo which mainly grows in a place where it grows out of the way can be clamped.
a, 9b to grasp and remove, or hold cutter 8
The bamboo cut and grasped or cut from the root is placed at a place where a crusher 25 is installed integrally with the compression feeder 23 or on a bucket of a civil engineering excavator. It is carried out to the crusher 25 integrated with the compression feeder 23, and the grips of the clamp levers 9a and 9b are slightly loosened and bamboo is directly inserted into the hopper 20, or the grips of the clamp levers 9a and 9b are slightly loosened and then the cutter 8 is used. The bamboo is cut into appropriate lengths, and the bamboo is split by rotating the movable compression roll 19a and the fixed compression roll 19b.
The harmful bamboo or tree can be easily and easily removed by crushing into small pieces.

Also, bamboo or trees growing on dangerous slopes can be safely cut and processed.

Further, the bamboo stems of the bamboo are also used for the boom 1 of the wooden excavator.
Can be pulled out of the ground at once.

Further, the crushed pieces can be effectively used as fertilizers and the like.
