Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device that can easily and quickly carry out transplant operations such as root cutting, root cutting, and planting ditches.

Conventionally, a device for the above purpose is a device in which a cutter mounting frame is attached to a backhoe, a pair of semicircular cutters are arranged in an annular shape on the same frame, and the bidirectional circular cutters are rotated as a unit toward the ground. There is. However, such excavation equipment had the following problems. (a) The pair of semicircular cutters must be assembled in a ring shape surrounding the plant, but if there is a fence or the like close to the rear of the plant, assembly becomes extremely difficult or impossible. (b) Also, since the pair of semicircular blades are assembled in a ring shape, the axis of rotation is inevitably well above the ground, which makes it impossible to secure a sufficient rotation radius underground, that is, the digging depth, and the roots of the plants. Cutting the part will significantly inhibit rooting.

It is an object of the present invention to provide a device that can solve all of the above-mentioned drawbacks of the prior art at once, and that can easily and quickly dig up even rotting plants.

The present invention is a tree digging device that can be attached to the tip of a rotating boom of a construction machine, etc., and is composed of (a) two parallel vertical members and one horizontal connecting member, and the horizontal member is attached to the rotating boom. (b) one semicircular cutter disposed within the gate frame and rotatably pivoted at both ends to the extension ends of two parallel vertical members; and (c) the gate frame. This invention relates to a plant digging device characterized by comprising a cutter rotation mechanism mounted on a frame.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The excavation device according to the present invention will be specifically described below with reference to an embodiment not shown in the accompanying drawings.

Fig. 1 shows an excavation device (I-frame component) according to the present invention attached to the tip of a two-inch rotating boom (3); This is accomplished by a drive cylinder (5) that rotates the mounting platen I (4) and the mounting platen +- (41) which are pivotally supported at the tip of the mounting platen I (4) and whose other end is fixed to a horizontal connecting member (11) which will be described later.

2 and 3 show the overall and detailed structure of the excavation device fil, which includes a pair of perpendicular members 0.0+, QOI, and one end of both members, which are arranged parallel to each other and spaced apart from each other like two. A concave frame (12) consisting of a horizontal connecting member (11)
) is attached to the horizontal connecting member (l]) midway on the platen l.
- (Installation number through 41) Concave frame (12
) is arranged in a semi-circular cutter (13) with pivot shafts (14) extending radially and in opposite directions at each end thereof.
, (14) are protruding, and both pivots (14),
(14) are the vertical members 001. It is rotatably supported by bearings (+5) and (15) installed at the extended end of (1 port). In the above configuration, the semicircular cutter (13) has an axis (X)-(X)t! connecting the two pivots (14), (14). It can be rotated freely. In this embodiment, the cutter rotation mechanism that rotates the semicircular cutter (13) has a first sprocket wheel (16) fixed to each pivot (14), and a second sprocket wheel (16) fixed to each pivot (14), and a second sprocket wheel (16) fixed to each pivot (14). Attach the sprocket wheel (17) rotatably,
An endless chain (18) is wound between both sprocket wheels (16) and (17), and each vertical member OI
It is constructed by attaching a chain moving cylinder (]9) on top and tying the telescopic rond end (20) of the cylinder to the endless chain (18). With this configuration, if the chain moving cylinder (19) is driven by °ζ,
The semicircular cutter (13) has a pivot (14), (14
) is the axis that connects! It is possible to rotate around Jl (X) and (X) within the range from point A to point B (approximately 220°) in Figure 3. Regarding other structural features of the excavation device according to the present invention, (30) is a concave frame (12).
This is an auxiliary cutter protruding from the most extended end of the vertical member 00), and by operating the rotating arm (3) of the component +11, the vertical member can be supported on the other side as shown in Figures 4 and 5. A recess (31) can be formed. Further, the vertical members of the gate-shaped frame (12) according to this embodiment are the horizontal connecting members (
11), and both vertical members (12)
, (12) can be freely set, and the semicircular cutter (13) having a diameter depending on the size of the excavated hole can be easily and quickly replaced and installed.

Next, we will talk about the tree digging work using the excavation device having the above configuration. First, the entire device +11 is attached to the tip of the rotating arm (3) of the component (2), and assistance is provided by driving the co-rotating arm (2). The cutter (30) is operated to cut a vertical member supporting recess (31) in the ground as shown in FIG. Next, place the extended end of the vertical member (IOL (10)) in the same recesses (31), (31), and insert the pivot (14).
, (14) so that the axis (X) - (X) connecting them is approximately at the same level as the ground. Then, by operating the chain moving cylinder (19) and rotating the semicircular cutter (13) in the direction of arrow C around the axis (X)-(X), the cutter (13) is cut into the ground and the plant is dug. Take the pick. In such excavation, the axis (X)-(X) is approximately on the same plane as the ground, so that the rotation locus (Y) of the cutter (13) can ensure sufficient depth at the minimum radius. Furthermore, since the excavation can be performed from the front of the plant (Z), even if there is a fence or the like behind the plant (Z), the excavation can be carried out regardless.

As described above, the plant digging device according to the present invention has the following effects.

(1) Since the tree can be excavated by simply rotating the cutter from the front, the tree can be dug easily and quickly regardless of the planting position.

(2) Since the axis of rotation of the cutter can be set at the same level as the ground, a sufficient digging depth can be ensured with the minimum radius, and the rooting of the plants will not be adversely affected.

(3) The cutter can be easily and quickly replaced depending on the type and size of the plants.
