[0001] ATTACHMENT DEVICE FOR TREE TRANSPLANTATION [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a digging device that is detachably coupled to a conveying means such as an excavator or a tractor and is used for transplanting trees. More specifically, And an object of the present invention is to provide a deforestation device for a tree transplantation which is capable of easily cutting and disposing soil around the root.

In general, trees such as a garden or a roadside tree are grown after being grown to a certain size for the purpose of landscaping, environment development, and urban planning. In the past, most of these tree-planting works are manually performed, have.

In order to perform conventional tree-planting work, first dig a pit at a graft site using a bucket or a shovel of an excavator, digging around the tree to be grafted in the same manner, and then perform a mining work and a mining work. Then, the trees are transferred to the graft site using an excavator or a crane, and the barrows and village cannons used for the mining work are removed from the transferred trees, and then planted in the pits at the graft site. Finally, using an excavator or a shovel to fill the space between the pit and the soil with soil, the tree transplanting work is completed.

In this way, the conventional tree-planting operation is not only complicated as a whole but also requires a certain amount of manual work such as excavation work, mining work, finishing work, and so on. It was the factor that caused the management failure of the landscaping company and the tree plantation.

Accordingly, in order to solve the above-mentioned problems, a tree planting apparatus capable of minimizing the manual work as in Korean Patent Laid-Open No. 10-1996-0036927 (published on November 11, 1996) has been developed. A known type of tree planting apparatus generally comprises an adapter mounted on an excavator, a tractor, a frame mounted on the adapter, and a spade installed on the frame, and the spade moves up and down by hydraulic pressure, do.

However, since the spade and the frame are formed integrally with each other, when the state of the soil and the root of the tree are different, the spade and the frame are all replaced in a form suitable for the spade and the frame. Therefore, The time required for the operation is increased.

In addition, since the above-mentioned tree transplanting apparatus does not separately cut off the roots of the trees that extend under the ground during the process of scouring the trees, the roots of the trees must be cut only by the force of lifting the spades. The size of the conveying means such as the conveying means and the like has been increased. As a result, when the access road and the work space are narrow, the operation can not be performed smoothly.

In addition, when the roots are cut off by an artificial force, the roots of the transplanted trees are not properly rooted as the soil around the roots is not attached due to the breakage of the roots, which eventually inhibits the growth of the trees .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, with reference to FIGS. 1 to 12, a detailed description will be given of a drifting apparatus for a tree transplant according to a first embodiment of the present invention.

The deforestation apparatus for tree planting according to the first embodiment of the present invention is disassemblably coupled to the front side of a traveling means 1 such as an excavator or a tractor for transplanting trees, (20), a flow member (20), a flow member (20), and a flow member (20). The mounting member (10) is mounted on an arm which is freely movable upward, (30), opening / closing means (40), tiltable member (50), and driving means (60).

Here, the support member 20 is coupled to the lower side of the mounting member 10, and the first receiving portion 21 is formed so that the central portion of the supporting member 20 is curved so as to cover one outer surface of the tree.

The support member 20 can be installed so as to be rotatable to the front and rear sides of the traveling means 1 via the support shaft 15 coupled to the mounting member 10, It is possible to prevent deformation or breakage even if a load is applied or an impact in the direction crossing the support shaft 15 is applied.

The flow member 30 has a size and shape corresponding to that of the support member 20 and is rotated through a hinge shaft 25 coupled to one end side of the flow member 30. A center portion of the flow member 30 has a first receiving portion The second receiving portion 31 is formed so as to cover the other outer surface of the tree.

The reason why the support member 20 and the flow member 30 are rotated through the hinge shaft 25 is that the outer surface of the tree to be grafted is wrapped around the tree to prevent the tree from falling down to one side Thereby preventing a safety accident as well as preventing the flow of trees to enable a convenient dredging operation.

The support member 20 and the flow member 30 are preferably formed to have diameters greater than the diameter of the trees so as to be able to transplant trees of various sizes through a single digging device. The first receiving portion 21 and the second receiving portion 31 may be formed in a circular or polygonal shape.

3, a cushion body C is preferably provided between the outer surface of the tree and the first receiving portion 21 and the second receiving portion 31 surrounding the outer surface of the tree, Is designed to narrow the distance over which the trees can move when the clearance between the first accommodating portion 21 and the second accommodating portion 31 is large, thereby enhancing the convenience and safety of the operation, and at the same time, So that the outer surfaces of the first receiving portion 21 and the second receiving portion 31 as well as the trees are prevented from being damaged.

The opening and closing means 40 is provided with a controllable distance between the support member 20 or the flow member 30 which is rotated through the hinge shaft 25 so that the hinge shaft 25, Is closed or closed as shown in Fig.

At this time, it is preferable that the opening / closing means 40 is a cylinder S whose length is variable and the distance is adjusted by the hydraulic pressure or the air pressure, (Not shown) in which the moving position is adjusted according to the rotating direction and the rotating amount of the rotating body.

The support member 20 opened and closed by the opening and closing means 40 and the end of the flow member 30, that is, the opposite side of the hinge shaft 25 are inserted into the insertion hole 35 and the support pin 36 fitted in the insertion hole 35 in a state in which the support member 20 and the flow member 30 are in close contact with each other.

5B, the cylinder body 42 in which the rod 43 of the cylinder 41 is put in and out, and the rod body 43 into the cylinder body 42, It is possible to prevent the rod 43 drawn into the cylinder body 42 from being drawn out arbitrarily by inserting the check valve 45 between the tube T for supplying the pressure to the cylinder body 42, So that the end portion of the cover 30 can be closed and fixed.

The opening and closing means 40 may be connected to the cylinder 41 (not shown) so that the supporting member 20 and the flow member 30, which are tightly contacted through the opening and closing means 40, The insertion hole 35, the support pin 36, and the check valve 45 may be provided together.

The pivoting members 50 are formed as a pair having the same size and corresponding shapes and are respectively installed to be pivotally symmetric with respect to the support member 20 and the flow member 30, Cutting portions 51 for cutting the soil around the roots and the roots of the trees are formed on the side end surfaces contacting with each other at the lower portion of the flow member 30.

The cutting portion 51 may be formed in a shape of at least one of a corrugated shape and a staggered shape so that the soil around the roots and roots of the tree can be more easily cut. 50 are rotated so as to be in contact with each other at a lower portion of the support member 20 and the flow member 30.

The pivoting member 50 includes a connecting portion 52 which is coupled to both sides of the support member 20 and the flow member 30 via the pivot 55 and pivots on both sides of the support member 20 and the flow member 30, A plurality of concave and convex portions 53 formed on the end surface adjacent to the rotary shaft 55 so as to be interlocked and interlocked with each other when the rotary shaft 30 rotates in close contact with each other, And a bent portion 54 which is coupled and rotated on both sides of the member 20 and the flow member 30.

At this time, the side of the connection part 52 connected to the support member 20 and the side connected to the flow member 30 can be held in mutual contact with each other so that the connection part 52 can not be pivoted until the cutting part 51 is pivoted until it abuts. It is preferable that it is formed in a shape having a shape.

The carburizing heat treatment can be performed on the inner circumferential surface or the outer circumferential surface of the bent portion 54. The reason why the heat treatment is performed only on one side surface not on both sides is that the bent portion 54 between the excavating operations continuously rubs The cut portion 51 is prevented from being dulled by keeping the sharp shape or by deforming the cut portion 51 into a more sharp shape.

However, the bent portion 54 is formed to be convexly curved in the outward direction, and the tilting member 50 is pressed in the direction of the ground, so that the force applied to the ground through the convexly formed outer circumferential surface It is preferable to heat-treat the outer circumferential surface convexly curved rather than the inner circumferential surface which holds the soil around the roots and roots of the tree.

The driving means 60 is rotatably coupled to both longitudinal sides of the support member 20 and the flow member 30 as shown in Fig. 6, and the end thereof is rotatably coupled to the connection portion 52, The driving unit 60 according to the first embodiment is a driving cylinder in which the length of the end portion is varied by hydraulic pressure or pneumatic pressure, .

The vibration generating means 70 is provided on at least one of the support member 20 and the flow member 30 so as to generate vibration. The vibration generating means 70 includes vibration generating means 70 Is for the purpose of enabling the roots of the tree and the soil of the root to be cut by the reciprocating motion by the vibration transmitted to the cut-off portion 51 while the pivoting member 50 is operated by the driving means 60. [

9 to 11, the driving apparatus 60 and the tiltable member 50 are installed on the outer surface of the support member 20 and the flow member 30, respectively, So that the supporting member 20 and the flow member 30 are fixedly attached to the supporting member 20 and the flow member 30 while being slid on the central portion and the end portion side of the supporting member 20 and the flow member 30, And a position adjusting member 80 that is fixed through the first and second guide holes 80a and 80b.

A through hole 81 penetrating through the upper and lower surfaces of the position adjusting member 80 is formed at both sides of the supporting member 20 and the flow member 30, And the fixing means F is fitted and fixed in a state where the through hole 81 and the control hole 82 are aligned with each other.

One or more guide protrusions 91 may be formed on one of the engagement surfaces of the position regulating member 80 and the support member 20 and the flow member 30 along the sliding movement direction, It is possible to form the guide grooves 92 corresponding to the guide protrusions 91 so that the guide protrusions 91 are inserted and moved so that the guide protrusions 91 can be stably and smoothly slidably moved. In this first embodiment, Guide grooves 91 are formed on the upper and lower surfaces of the upper and lower surfaces of the flow control member 20 and the flow member 30. Guide grooves 92 are formed in the upper and lower portions of the position adjustment member 80 corresponding to the guide protrusions 91, .

As the position adjusting member 80 moves, the distance between the driving unit 60 and the connecting unit 52 is also changed. Thus, the rotating unit 50 is fixed to the position adjusting member 80 Since the size of the bent portion 54 can not be deformed in this process, the rotating member 50 is detached before the position adjusting member 80 is operated And then it is necessary to replace the tilting member 50 with the tilting distance.

In order to allow the position regulating member 80 to move in a state of being firmly adhered to the support member 20 and the flow member 30, the engagement surface is formed in a ' And the flow member 30 are closely contacted to the remaining three surfaces except for the surfaces facing each other.

However, the shape of the position regulating member 80 is different from the shape of the position regulating member 80 so that the upper surface and the rear surface of the supporting member 20 (the surface facing the traveling means 1) And a front surface (a surface facing the opposite side of the traveling means 1).

The supporting surface of the support member 20 and the flow member 30 may be slid in a state in which the coupling surface is formed in a ' A recessed portion may be provided along the sliding movement direction on the side where the members 30 are opposed to each other so that the moving position of the position adjusting member 80 is maintained even when the face on which the supporting member 20 and the flow member 30 face each other is in close contact It is preferable to be able to easily adjust it.

The reason that the shape of the surface of the position adjusting member 80 coupled to the support member 20 and the flow member 30 is' a '', 'a' When the support member 20 and the flow member 30 are formed in a circular, elliptical or polygonal shape, the support member 20 and the flow member 30 are in close contact with each other It can be formed in various shapes without being disturbed and easily slidable along the support member 20 and the flow member 30. [

The operation of the dredging device for tree planting having the above-described structure will be described below.

The opening and closing means 40 and the driving means 60 are connected to the traveling means 1 through the mounting member 10 while the flow member 30 is directed to the front side, After connecting the tubes for operation to supply pressure, the job ready state is completed.

Here, the tiltable member 50 can be coupled to the traveling means 1 while being in contact with each other, but it is difficult to keep the tiltable member 50 fixed by the bent portion 54 when the tiltable member 50 touches the ground, In order to enclose and fix the outer surface of the tree through the support member 20 and the flow member 30 to be described later as well as the easy coupling with the means 1, It is preferable that the support surface is supported by the cut portion 51 so that the support surface is supported.

At this time, in order to retrieve the tree to be grafted, first, the opening and closing means 40 is operated to rotate the flow member 30 about the hinge axis 25 so that the support member 20 and the flow member 30 The traveling means 1 is operated so that the center portion of the supporting member 20 and the flow member 30 are moved so as to cover the outer surface of the tree by operating the traveling means 1 in a state in which the opposite side of the hinge shaft 25 is open.

The supporting member 20 opened through the opening and closing means 40 and the end of the flow member 30 are operated to be closed so that when the supporting member 20 and the flow member 30 are in close contact with each other, When the check valve 45 is provided together with the support pin 36 inserted in the insertion hole 35, the state of being closed is further secured So that it can be prevented more effectively from being arbitrarily opened or flowing even in the process of scouring the trees planted on the hard ground.

Next, in a state where the outer surface of the tree is wrapped around the support member 20 and the flow member 30, the tilting member 50 is lowered until the connection portion 52 is brought into close contact with the ground, The driving means 60 is operated in a state of being vertically pressed to cut the soil around the roots and the roots of the trees through the cutting portion 51 while the pivoting member 50 is rotated.

When the cutting portion 51 abuts and the soil of the tree and the surrounding soil are cut, the inner side surface of the bent portion 54 is supported by the lower portion of the tree. , And the tree thus demolished can be moved to a set position.

Since the mounting member 10 and the support member 20 are rotatably coupled through the support shaft 15, even when the ground surface is inclined, the ground surface can be pressed in accordance with the inclination, The excessive force is applied to the mounting member 10 coupled to the traveling means 1, so that it is possible to prevent the excessive load from being applied to the mounting member 10. Accordingly, There is an advantage that the durability can be increased.

At this time, the vibration generating means 70 operates together while the pivoting member 50 is rotated, and acts as a reciprocating movement of the cutout portion 51 by the vibration, so that the roots and the soil are easily cut, The cutting portion 51 is also formed in a shape having either a simple straight line shape, a non-arcuate shape, a zigzag shape, or both, so that it is possible to more easily cut the roots of the tree as well as the soil.

Even if the roots of the trees and the surrounding soil are easily cut through the vibration generating means 70 and the cutting portion 51 with a small force and they are used in combination with the small traveling means 1, It is possible to reduce the time and cost required for the operation and to move freely even if the access road and the work space are narrow. Therefore, convenience and efficiency of the work are increased, and as the cutting portion is smoothly cut to a predetermined size, It is possible to minimize the damage such as disconnection from the position, and can be easily mobilized after implantation.

It is preferable that the bent portion 54 is pivoted so that the end of the cutting portion 51 is positioned higher than the lowermost position of the connecting portion 52. This is because the pivoting member 50 is provided in a size suitable for the size of the tree, So that the tilting member 50 is rotated in a state where the coaxial shaft 55 is located as close as possible to the ground, thereby to scoop up a predetermined amount of soil and roots.

The connecting portion 52 is brought into close contact with the ground surface while the outer surface of the tree is wrapped around the tree so that the turning member 50 is rotated through the driving means 60 so that the cut portions 51 are engaged with each other This is because the pivoting member 50 is installed in a size suitable for the size of the tree and the pivoting member 50 is moved in a state in which the pivoting shaft 55 is positioned as close as possible to the ground So that the soil and roots of a predetermined size can be thoroughly scraped off.

If the tilting member 50 is operated without pressurizing the soil around the trees, even if the roots and the soil are smoothly cut through the vibration generating means 70 and the cutting portion 51, the bending portion 54 and the cut portion 51 can not be inserted all the way down to the ground so that only the soil on the ground surface is broken and it is difficult to bend the tree. When the connecting member 52 is not completely in contact with the ground, The soil and roots of a predetermined size can not be slaughtered and normal growth can not be achieved even after transplantation.

Particularly, the pivoting member 50 is coupled with the support member 20 and the flow member 30 so as to be engaged with each other through the concavo-convex portion 53 provided in the connection portion 52 as shown in Figs. 8A and 8B The force transmitted to the connecting portion 52 through the driving means 60 driven by the hydraulic pressure can be simultaneously turned on the tilting member 50 regardless of whether the force transmitted to the connecting portion 52 is strong.

Here, the connection portions 52 are coupled to each other so as to rotate in an organic manner, and the force transmitted to both sides of the support member 20 and the driving member 60 provided on both sides of the flow member 30 is transmitted. The dredging operation can be performed more easily than when the uneven portion 53 is not provided.

Thus, even when different forces are transmitted to the tiltable member 50, the tiltable portion 53 is always uniformly rotated at the same time, so that malfunctions and overloads of the tiltable member 50 and the drive means 60, It is possible to prevent the breakage due to the breakage of the workpiece, and to provide a safe and smooth operation condition for the work.

If a tree of a size larger than the predetermined size is to be excavated after the excavation work for a tree of any size is completed, the tilting member 50 installed between the existing excavation works is first removed, and then the position adjusting member 80 The through hole 81 and the control hole 82 are aligned with each other and then the fixing means F is inserted and fixed and then the rotating member 50 ).

At this time, it is preferable that the position adjusting member 80 is moved so as to have the same distance from the center of the supporting member 20 and the flow member 30, that is, to be symmetrical with respect to each other, So that the user can quickly and smoothly perform the dredging operation while preventing the equipment from being overloaded.

In this way, even if the size of the tree to be worked is changed, the tilting operation is performed by replacing the tilting member 50 with the installation position of the driving means 60 being adjusted according to the size of the tree, And the manufacturing cost can be reduced.

Further, by heat treating any one of the inner circumferential surface and the outer circumferential surface of the tiltable member 50, the durability of the product is increased and the service life is increased, and even if the opposite surface which is not heat- It is possible to prevent dulling and to perform a continuous dredging work even without performing a separate machining operation, so that the convenience and efficiency of the work are increased and the maintenance cost is reduced.

The scope of the present invention is not limited to the above-described embodiments, but may be embodied in various forms of embodiments within the scope of the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
