FIG.

A tree planting and pruning device 1 according to an embodiment for carrying out the present invention will be described with reference to the drawings.
FIG. 1 is an external perspective view of a tree planting and pruning apparatus 1.
The planting / pruning work device 1 includes a foundation frame 11, a support column 12, a support column 13, an arm unit 14, a joint unit 16, a work machine 17, a work machine drive source (not shown), and an arm rotation adjustment unit 18 (FIG. 7). And a hoisting machine 19.

The base frame 11 is a structure in which a highly rigid metal member is combined in a horizontal frame shape, and a base portion for standing the support column 13 is provided in the base frame 11.
In consideration of loading the foundation frame 11 on the light freight vehicle 5, the width is set to a size that fits in the loading platform of the light freight vehicle 5. The depth shall not exceed 1/2 in the longitudinal direction of the loading platform.
The column support frame 12 is formed in a frame shape with a highly rigid metal member, and one side of the column support frame 12 and one side of the base frame 11 are joined so that the column support frame 12 and the base frame 11 are perpendicular to each other. . At the upper end of the combined column support frame 12, it is combined with the column 13 and supports the upright of the column 13.
The column 13 is formed of a metal member in a cylindrical shape, and is coupled to the base portion of the foundation frame 11 on the lower circle surface. Considering loading and working on the light freight vehicle 5, it is preferable to form a columnar shape with a diameter of about 140 mm and a total length of about 2500 mm. In addition, the upper and lower movable ranges of the arm part 14 are coupled to the support frame 12.
In the embodiment for carrying out the present invention, the column cylinder portion is provided as a cylindrical portion 33 that is formed in a cylindrical shape with a metal member and is attached so that the outer periphery of the column-shaped column 13 can be rotated and moved up and down freely. It is done.
The support column 13 has a function of holding the arm portion 14 at a predetermined height as will be described later.
A connecting member 34 having a hinge 32 and capable of rotating 360 degrees on the upper circular surface of the support 13 is provided at the tip of the support 13. The connecting member 34 is connected to the hoisting machine main body 91, and the angle is changed up and down by the action of the hinge 32 according to the height of the arm portion 14.
As the arm unit 14 rotates, the arm unit 14 and the hoisting machine 19 work in conjunction with each other to smoothly rotate.

The arm portion 14 includes a square tubular outer tube 41 and an inner tube 42 having a size that can be inserted into the outer tube 41, and sliding the inner tube 42 within the outer tube 41 allows the arm portion 14 to move. It has a structure that can be expanded and contracted.
Furthermore, the inner tube 42 has two parallel lines 43 that support the outer tube 41 disposed in the longitudinal direction of the surfaces of the upper and lower surfaces, and an upper longitudinal portion from the height ½ of the surface of each side surface. And a single line 43 that supports the outer tube 41 disposed in the direction, and has a structure in which the inner tube 42 and the outer tube 41 slide more smoothly by bringing the inner tube 42 and the outer tube 41 into line contact.
The arm portion 14 is coupled to a coupling portion 31 attached to a cylindrical portion 33 of a metal member that is rotatable and movable up and down on the outer periphery of the support column 13, and is indirectly coupled via the cylindrical portion 33. It is combined with the support 13. Therefore, the arm portion 14 can rotate about the support column 13 and move up and down on the support column 13.

The outer tube 41 is preferably a square metal tube of approximately 150 mm square considering the load during work and the weight of the work machine 17 described later.
However, the square steel pipe that can be purchased has a minimum thickness of 4.5 mm. If this is adopted, the rigidity becomes high, but the weight of the entire apparatus becomes heavier than necessary.
Therefore, a 150 mm x 50 mm x 3.2 mm light grooved steel is used, and the opening side of the "U" is matched and welded to a metal flat plate with a plate thickness of 3.2 mm and a width of about 75 mm, and a square of about 150 mm square Weight reduction is achieved by forming a metal tube.
The length is preferably about 1600 mm in consideration of loading on the light freight vehicle 5.
The inner tube 42 is preferably a square steel tube of approximately 125 square × 3.2 mm thick considering rigidity and weight.
Since the arm portion 14 does not have a driving device such as a hydraulic pressure, sufficient rigidity can be obtained with the above dimensions.
The length is preferably about 1600 mm from the same viewpoint as the outer tube 41.

2 is a cross-sectional view taken along line AA of the arm portion 14 in FIG.
The track 43 disposed in the inner tube 42 is preferably a cylindrical reinforcing bar. At that time, the upper and side reinforcing bars where the weight of the inner tube 42 is not directly applied may be thinner than the lower reinforcing bars.
When the outer tube 41 and the inner tube 42 are designed as described above, the upper and side reinforcing bars preferably have a diameter of approximately 6 mm, and the lower reinforcing bar preferably has a diameter of approximately 12 mm.
In consideration of the balance of the inner pipe 42 that rides on the two lines 43, the lower line 43 is preferably disposed about 10 to 15 mm from both ends of the inner pipe 42 in FIG. This is because if the distance between the two lines 43 is extremely narrow, the inner tube 42 tends to rattle in the clockwise or counterclockwise direction in FIG.
The side track 43 is preferably disposed approximately 15 mm below the upper end of the side surface. This is because the inner tube 42 is likely to rattle in the clockwise or counterclockwise direction in FIG. 2 in the outer tube 41 when extending from the upper end of the side surface to below the height ½. .
It is preferable that the track 43 on the lower surface and the side surface has a length disposed in the entire expansion / contraction range.
On the other hand, the two parallel lines 43 arranged on the upper surface have the working machine 17 side tip depending on the weight of the working machine 17 and the inner pipe 42 when the inner pipe 42 is extended, and the upper surface on the column 13 side. This has the effect of reducing the resistance generated when the end is in strong line contact with the upper side of the outer tube 41. In consideration of this, the two lines 43 on the upper surface of the inner tube 42 may be disposed at a length of a part of the upper end of the upper surface on the column 13 side. Therefore, it is sufficient that the two lines 43 on the upper surface have a length of about 100 mm.
By the line 43, the contact resistance between the outer tube 41 and the inner tube 42 is greatly reduced, and the arm portion 14 can be smoothly expanded and contracted by human power. A greater effect can be obtained by using lubricating oil.
The dimensions and members shown in the present embodiment are examples, and the present invention is not limited to these.
