Description

A cutting device for a transplanting tree

More particularly, the present invention relates to a cutting apparatus for a tree transplanting apparatus, which is operated in the direction of a buried wooden pillar from a surrounding buried pillar of a wooden pillar in a state of being fastened to an end of an excavator in a tree transplanting operation, And a cutting device for cutting a bottom column and cutting the simultaneously cut wood from the buried ground.

Trees are generally cultivated in forest areas or in soil-rich areas or grow in natural conditions. In recent years, trees are being scientifically cultivated and managed in specific areas in order to form dense forests.

In addition, it is common for the buildings to be constructed together with the landscaping for aesthetics around the buildings when they are constructed or refurbished. Of course, large-scale transplanting of trees has also been carried out in forest areas where dense forests and forests are not dense.

As such, there are many construction works for transplanting trees. Therefore, there is a problem that the transplanting work of trees should be performed quickly and conveniently.

However, most of the general tree transplantation process is accompanied by the individual labor force of various workers. Therefore, the fatigue of the workers is increased and the speed of the transplanting operation is also delayed.

Most of these common wood grafting processes are carried out by a number of workers using a shovel in the burrows around the tree to be transplanted, cutting the root branches that are buried in the burrows with a saw, The cutting process of the grafted tree is completed after cutting through the saw.

Then, to lift the tree from the burying area, the tree is tied with a rope or a chain, then the tree is lifted using a crane, and then the truck is loaded on a truck or a truck.

After that, the grafted tree was moved to a place to be transplanted. Then, the grafted soil was shoveled to form a graft hole. Then, the grafted tree was pinched with a chain or a rope and moved to a pit for transplanting into a crane. , The tree is planted directly in the pit and the surrounding soil is poured into the pit again to complete the tree transplanting work.

As a result, the process of tree planting has not been improved yet, because the conventional tree planting process still follows the method using the individual workforce and the crane of the workers from the past. Therefore, The fatigue is increased, the fatigue concentration is lowered, and the accident rate is increased. Especially, the progress speed of the tree planting is lowered and the efficiency of the tree planting work is lowered.

On the other hand, the prior art documents described below disclose techniques for wood implantation, but most of these techniques use cutting edges of an automated machine to remove the root roots of the wood for transplantation of trees, But it is a matter of continuing problems that can not be guaranteed to prevent damage or damage to the grafted tree in the process of transferring the tree before the graft. to be.

In addition, in the following prior art documents, trees are pulled out with the cutting roots of the grafted tree removed in the process of digging through the divided cutting edges. In the process of removing the roots of the trees, the cutting edges are roughened , The slope movement is implemented and the roots are cut through the landfill around the tree. Therefore, the size of the wood is small, and since the size of the wood is small, in the process of drawing and transporting the wood, Which causes root damage to occur, and the nutrients are not sufficiently supplied because the size of the powder is less than the appropriate standard, which may inhibit the growth of the tree.

In other words, in the case of tree transplantation, when the wood is grown larger than the appropriate standard, it is advantageous for the growth of the tree. Therefore, when digging down the landfill around the tree during the culling process, The techniques disclosed in the following prior art documents are based on a method in which the cutting edges descend the landfill around the trees in a form inclined in the direction of the roots for cutting the roots, And there is a problem in that the shape of the minute is often inverted due to its own weight due to the inverted triangular structure.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. And it should be interpreted based on the technical ideas throughout the specification taking into consideration that various modifications are made.

The terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary terms and the inventor may appropriately define the concept of the term in order to best describe its invention And it should be construed as meaning and concept consistent with the technical idea of the present invention.

Therefore, the embodiments described in the present specification and the configurations shown in the drawings are only the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 to 3, the cutter for cutting a tree according to the present invention comprises a block body 100 having a polygonal shape. The block body 100 is preferably of an octagonal shape, 100 are formed of an open / close block 101, 101a which are opened and closed in a mutually adjacent state, and the inside of the block body 100 forms an octagonal hollow 102 .

4 and 5, the hollow 102 serves as a space for holding a wooden column (WC). The hollow 102 has a larger diameter than the diameter of the hollow 102, When the diameter is small, the wooden column WC can not be properly held. In the process of drawing the wooden column WC, the wooden column WC collides with the inner side of the block body 100, The elastic tube 170 shown in FIGS. 10 to 11 may be further provided inside the block body 100 in view of damage.

The hydraulic tank 180 for supplying the fluid into the elastic tube 170 may be fixed to an outer diameter portion of the block body 100. The fluid supplied from the hydraulic tank 180 It is preferable that the ejector 190 is installed in such a manner that the ejector 190 is inserted into any one of the block bodies 100 Do.

The elastic tube 170 is coupled along the inner diameter of the block body 100. The elastic tube 170 elastically holds a wooden column WC that enters the hollow 102, And the like.

Of course, since the diameter of the wooden pillar WC differs depending on the type and growth period, the wooden pillar WC having a diameter much smaller than the diameter of the hollow 102 enters the hollow 102 (WC) due to the large diameter difference between the wooden pillar (WC) and the hollow (102) in the process of removing and drawing the wooden pillar (WC) The wooden pillar WC can be fully held and can be bent and supported.

On the other hand, when the wooden pillar WC is relatively smaller than the diameter of the hollow 102 but the difference is small, the expansion of the elastic tube 170 is also relatively small due to the small diameter difference between the wooden pillar WC and the hollow 102 So that the wooden pillar WC can be held in a state of being inflated to be bent and supported.

That is, the elastic tube 170 can flexibly hold and support the wooden pillar WC that enters the hollow 102 regardless of the diameter of the wooden pillar WC, And the degree of expansion force of the elastic tube 170 according to the adjustment of the hydraulic pressure supplied to the inside of the elastic tube 170. In other words, the wooden pillars WC having different diameters according to the degree of expansion of the elastic tube 170 can be held and supported.

The injector 190 inserted into one of the block bodies 100 adjusts the injection and injection amount of the fluid as shown in FIG. 10 and FIG. 11, and supplies the fluid from the hydraulic tank 180 The elastic tube 170 and the elastic tube 170 are connected to each other.

The hydraulic tank 180 for supplying the fluid to the injector 190 is connected to the injector 190 by supplying fluid to the injector 190 while being fixed to an outer diameter of the block body 100, It is also collected.

The configuration of the injector 190 may be described in detail with reference to FIG. That is, the injector 190 is constituted by an electronic control unit (not shown) on the upper side and a mechanical control unit (not shown) on the lower side with reference to the inlet 190L, which is the inflow path of the fluid configured on the side.

Here, the electronic control unit may open / close the return throttle 190k according to the presence / absence of energization, and may include a ball 190e formed on the return throttle, a magnetic bar 190d formed on the ball, A first spring 190c surrounding the bar, a third spring 190j interposed on the upper portion of the magnetic bar, and an electromagnetic coil 190b formed outside the third spring.

The ball 190e opens and closes the return throttle 190k depending on whether the electromagnetic coil 190b is energized or not.

The magnetic bar 190d formed on the upper portion of the ball reacts and rises due to the magnetic force generated by the energization of the electromagnetic coil 190b and is lowered by the non-passage of the magnetic coil 190d. The return throttle 190k can be opened due to the upward movement of the return throttle 190k, and the ball 190e is also lowered at the time of descending.

The first spring 190c interposed between the magnetic bar 190d and the magnetic bar 190d is energized when the electromagnetic coil 190b is energized while the electromagnetic coil 190b is energized. And is compressed together with the lowering of the magnetic bar 190d.

The third spring 190j interposed in the upper portion of the magnet is compressed by the upward force of the magnetic bar 190d when the electromagnetic coil 190b is energized, The magnetic bar 190d is lowered while being stretched by the restoring force.

A magnetic force is generated to energize the magnetic bar 190d when the energizing coil 190b is energized, and when the magnetic coil 190d is not energized, And is lowered by the elastic restoring force of the spring 190j.

That is, the magnetic bar 190d is lifted and lowered according to whether or not the energization of the electromagnetic coil 190b is applied, so that the return throttle 190k can be opened and closed according to the lifting and lowering of the ball 190e interlocked with each other.

Meanwhile, the machine control unit includes a control chamber 190f formed at the lower end of the return throttle, a supply throttle 190m formed at one side of the control chamber, a plunger 190n constructed at a vertically lower portion of the control chamber, A second spring 190g interposed in a manner to enclose the plunger, and a hole 190i formed in a vertically lower portion of the needle 190i.

The control chamber 190f is formed at the lower end of the return throttle 190k and functions as a space in which the hydraulic pressure is regulated by the amount of fluid supplied from the inlet 190i.

The supply throttle 190m formed at one side of the control chamber passes the fluid supplied from the control chamber and sends the fluid to the chamber 190h connected to the lower portion.

The plunger 190n constructed in the vertical lower portion of the control chamber ascends and descends according to the amount of fluid supplied to the control chamber. This is caused by the hydraulic pressure corresponding to the amount of fluid secured in the control chamber 190f, This is because the plunger 190n rises when the sum of the injected amount of the fluid to be injected is less than the elastic restoring force of the second spring 190g surrounding the plunger 190n. Here, the amount of fluid secured in the control chamber corresponds to the case where the return throttle 190k is opened.

On the other hand, when the hydraulic pressure corresponding to the fluid amount secured in the control chamber 190f is stronger than the elastic restoring force of the second spring 190g surrounding the plunger 190n, the plunger 190n is lowered. The amount of fluid secured in the control chamber corresponds to the case where the return throttle 190k is closed. That is, as the discharge of the fluid is blocked due to the closing of the return throttle 190k, a large amount of fluid is secured in the control chamber 190f and the plunger 190n is lowered as the hydraulic pressure is increased so that the needle 190o blocks the hole 190i The injection of the fluid stops.

The needle 190o constructed vertically at the lower end of the plunger moves up and down while interlocking with the plunger 190n to open and close the hole 190i.

The second spring 190g interposed in the form of surrounding the plunger is compressed and tensioned according to the amount of fluid secured in the control chamber. When the return throttle 190k is closed, a large amount of fluid supplied to the control chamber When the return throttle 190k is opened, the hydraulic pressure is reduced due to insufficient securing of the amount of fluid supplied to the control chamber 190f, and when the return throttle 190k is opened, the plunger 190n is compressed do.

The needle 190o connected to the lower end of the plunger 190n can be opened and closed by interlocking with the plunger 190n while opening and closing the hole 190i. The opening 190i is opened.

Hereinafter, the operation of the injector 190 will be described.

The fluid supplied to the injector 190 flows into the control chamber 190f from the high pressure pipe (not shown) through the inlet 190L and the supply throttle 190m. The control chamber 190f is connected to the return line of the fluid returned through the return throttle 12 opened by the solenoid valve.

When the hydraulic tank 180 is in operation and is supplying fluid through a high-pressure pump (not shown), the injector 190 performs the following functions.

(High pressure acts on the plunger 190n), opening of the injector (injection start), opening of the injector full, and closing of the injector (injection end).

These functions are controlled by distributing the high-pressure fluid to the components of the injector 190. When the hydraulic pressure in the rail is lowered and the hydraulic tank 180 is stopped, the elastic return force of the second spring 190g causes the needle 190o ) Closes the injector 190i.

Injector closed state (high pressure acts on plunger 190n)

As an initial state, the injector is closed in the initial state. The third spring 190j brings the ball 190e into close contact with the sheet of the return throttle 190k. The high pressure acts on the control chamber 190f as it is. The same pressure acts on the chamber 190h of the nozzle. The sum of the force due to the fluid pressure acting on the upper end of the plunger 190n and the tension of the second spring 190g pushes down the nozzle and the high pressure acting on the slope 8 of the nozzle needle 16 And pushes the nozzle upward to open it. At this time, however, since the downward force is stronger, the nozzle is closed in close contact with the pores 190i.

Injector opening (injection start)

At the initial position of the injector, the solenoid valve is controlled by the pickup current. The pickup current is used to allow the solenoid valve to open rapidly. The short switch-on time required is triggered by the solenoid valve at the high voltage supplied by the ECU.

The magnetic force of the triggered electromagnetic coil 190b becomes stronger than the tension of the third spring 190j. When the magnetic bar 190d lifts the ball 190e from the valve seat, the return throttle 190k is now opened. After a short time has elapsed, the high pickup current is changed to a weak holding current (Holding current) and acts on the electromagnetic coil 190b.

When the return throttle 190k is opened, the fluid can now return from the control chamber 190f to the hydraulic tank 180 through the hollow portion at the top thereof and the fluid return line in turn, and then through the recovery port 190a. Since the supply throttle 190m hinders perfect pressure equilibrium, the pressure in the control chamber 190f is lowered. Therefore, the pressure in the control chamber 190f becomes lower than the pressure in the chamber 190h still maintaining the pressure level of the rail. When the pressure in the control chamber 190f is lowered, the force acting on the upper end of the plunger 190n is reduced, and eventually the needle 190o is opened and the injection of the fluid through the pores 190i is started.

Injector Pool Open

The speed at which the needle 190o is opened is determined by the difference in the flow rate between the supply throttle 190m and the return throttle 190k. The plunger 190n reaches its upper stopper (= the fluid cushion portion), and stops the hydraulic pressure while maintaining the position.

This cushion is formed by the flow of the fluid being adjusted between the supply throttle 190m and the return throttle 190k. Now, since the pores 190i are completely opened, they are injected into the elastic tube 170 at a pressure substantially equal to the pressure of the common-rail.

The distribution of the fluid in the injector proceeds in a similar fashion to the distribution of the fluid in the open phase. The fluid injection amount is independent of the rotation speed of the hydraulic tank 180 and the rotation speed of the high-pressure pump, and is proportional to the energization time of the solenoid valve when the pressure is constant. That is, time controlled injection.

Injector closing (injection end)

When the current no longer flows into the injector, the third spring 190j pushes down the magnetic bar 190d, so that the ball 190e closes the return throttle 190k. When the return throttle 190k is closed, the fluid in the high pressure state is again supplied to the control chamber 190f through the supply throttle 190m and becomes the same pressure state as the rail pressure. This raised pressure acts on the upper end of the plunger 190n with a large force. Now, the sum of the force from the control chamber 190f and the tension of the second spring 190g becomes larger than the force acting on the needle 190o, and the needle 190o is closed. The amount of fluid passing through the feed throttle 192m determines the closing speed of the needle 190o. When the needle 190o is again brought into contact with the sheet of the pores 190i, the pores 190i are closed and the injection of the fluid is terminated.

The reason why the needle 190o is indirectly controlled as described above is that the force necessary for quickly opening the needle 190o can not be directly formed using the solenoid valve. At this time, the control fluid, which is required in addition to the amount of fluid to be injected, flows to the fluid return line through the return port 190a through the return throttle 190k of the control chamber 190f.

In addition to the control fluid, there is fluid leaking from the needle (190o) barrel and the plunger (190n) barrel, and thus the control fluid and the leaked fluid are returned back through the return line including the overflow valve, the high pressure pump, And returned to the hydraulic tank 180.

On the other hand, a locking induction cylinder 110 is provided on the upper surface of one of the opening and closing blocks 101 and 101a to release or arm the locking required for opening and closing the opening and closing blocks 101 and 101a. The end of the induction cylinder 110 is hinged on the opening and closing block 101 and the rod end of the locking induction cylinder 110 is hinged to one end of a hook 111 described later.

The hook 111 is hinged to one end of the rod of the locking induction cylinder 110 and the other end of the hook 111 is fastened and fixed to the upper surface of the other one of the opening and closing blocks 101 and 101a And the pin 121.

Therefore, the hook 111 rotated by the backward retracting action of the locking induction cylinder 110 is locked or released from the engagement pin 121, and is immediately opened to the open / close block 101, 101a in the adjacent state And is in a state immediately after closing.

On the other hand, as a locking means for the pair of the open / close blocks 101 and 101a, a locking protrusion 122 is formed at the end of one of the open / close blocks 101 as shown in FIG. 9, The locking groove 122a is formed at the end of the locking groove 101a and the locking induction cylinder 110 installed vertically at the upper end of the locking block 101a in which the locking groove 122a is formed, Lt; RTI ID = 0.0 > 101, 101a. ≪ / RTI >

That is, when the pair of the open / close blocks 101 and 101a are closed, the locking protrusion 122 enters the locking groove 122a. At this time, the power of the locking induction cylinder 110, The pistons pass through the holes formed in the locking grooves 122a and pass through the holes formed in the locking protrusions 122. As a result, the pair of the opening / closing blocks 101 and 101a are locked with respect to each other, When the locking projection 122 enters the inside of the locking induction cylinder 110, the locking of the locking protrusion 122 is released, so that the pair of the opening / closing blocks 101 and 101a are unlocked.

The open / close blocks 101 and 101a are opened / closed in a hinged manner by a cylinder power because the block bodies 100 are hinged at one side ends of both sides. In this case, a pair of open / close cylinders 120 and 120a And the opening and closing cylinders 120 and 120a are installed on the blocks of the block body 100 positioned at the left and right rear sides of the opening and closing blocks 101 and 101a.

At this time, each end of the open / close applying cylinder 120, 120a is hinged to each block top surface of the block body 100, and each end of the rod of the open / close applying cylinder 120, 4 and 5, the open / close blocks 101 and 101a are opened or closed in a hinged manner with respect to the hinge axis by the structure in which the open / close application cylinders 120 and 120a are hinged to the upper surface, .

In the block body 100, an arm coupling part 130 is coupled to the block end 100 of the excavator at an outer side of the blocks opposite to the open / close blocks 101 and 101a. Since the arm fastening portion 130 is formed with a fastening pin (not shown), the arm end is automatically engaged in a manner that the arm end portion is engaged with the fastening pin in accordance with the arm operation of the excavator, It is not required to fasten the pins by inserting them so that the convenience of the work can be provided.

141a, 141b, and 141c are formed as the linear cutting means 140. The linear cutting means 140 and the curved cutting means 150 are formed on the block body 100, It is preferable that the slide passage tubes 141, 141a, 141b, and 141c are formed of four pieces.

As shown in FIG. 2, the two slide passage pipes 141 and 141c of the slide passage pipes 141, 141a, 141b and 141c are moved from the position of the block body 100 on which the arm fastening section 130 is mounted to the adjacent left and right sides And the remaining two slide passage pipes 141a and 141b are formed in a shape protruding from one side of the upper surface of the block body 100 facing the block body 100, And is formed in a shape protruding from each of the upper surfaces of the other side so as to penetrate to the lower surface of the block body 100 and be inclined in a straight line toward the center point of the hollow 102.

The first cylinders 142, 142a, 142b, and 142c are fixedly installed in the sliver passage pipes 141, 141a, 141b, and 141c, respectively. The first cylinders 142, 142a, 142b, 143a, 143b, 143c slidably operated in each of the slide passage tubes 141, 141a, 141b, 141c, and each of the slide members 143, 143a 144b, and 144c are coupled and fixed along the outside of the ends of the first, second, third, and fourth cutting edges 144a, 143b, and 143c.

Therefore, the slide members 143, 143a, 143b, and 143c slide in the slit passage pipes 141, 141a, 141b, and 141c by the forward and backward movements of the rods of the first cylinders 142, 142a, The first cutting edges 144, 144a, 144b, and 144c, which are interlocked with the slide members 143, 143a, 143b, and 143c, are also lowered or raised.

Of course, the first cutting edges 144, 144a, 144b, and 144c are linearly moved in a manner that they are aligned toward the hollow 102 at the time of lowering due to the inclined structure of the slide passage pipes 141, 141a, 141b, And the cutting edges of the wood in the vertical direction inclined by the straight movement of these first cutting edges 144, 144a, 144b, 144c are easily cut as shown in Fig.

In addition, since the ends of the rods of the cylinders 142, 142a, 142b, 142c transmit power by pushing the slide members 143, 143a, 143b, 143c, the occurrence of overload in the excavation process can be relatively minimized However, in the past, as the rod of the cylinder transmits the power by pulling the cutting edge, the overhead of the drilling process is relatively increased, so that the residual power system using the cylinder is frequent.

The block body 100 is further provided with a curved cutting means 150. This curved cutting means 150 prevents the miniaturization of the minute size due to the root cutting of the linear cutting means 150 And serves as a complementary cutting means for preventing the cracking phenomenon occurring during the transportation of the grafted tree.

In other words, when the size of the grafts of the grafted tree is less than the appropriate standard, the supply of nutrients due to the miniaturization of the grafts is not properly provided, which hinders the growth of the grafted tree. Therefore, the grain size should be maintained above a proper standard, In the root cutting process, the fractions of wood are inversely triangular structure, so that the lower part of the fragile fragile wood is fragile due to the weight of wood, and this also acts as a factor for inhibiting the growth of the transplanting tree. Cracking of the grains can also cause damage to the root roots during transportation of the grafted tree.

Therefore, the curved cutting means 150 is provided as a role of suppressing and preventing the miniaturization of the components that can be caused by the operation of the linear cutting means and the breakage of the powder, As a result, it is possible to minimize the occurrence of clearance of trees during transportation.

The curved cutting means 150 is required to have the configuration of the fixing members 151 and 151a, and the fixing members 151 and 151a are preferably composed of two.

One of the fixing members 151 and 151a of the fixing members 151 and 151a may be a block member positioned between the slide passage pipes 141 and 141a protruded from the upper surface of the block member 100, And the other fixing member 151a is fixed to the outer surface of the block of the block body 100 positioned between the slide passage pipes 141b and 141c protruded on the upper surface of the block body 100. [ And is protruded from the side surface of the block body 100 to the upper and lower sides.

Each of the side surfaces of the fixing members 151 and 151a is provided with second cylinders 152 and 152a and the ends of the second cylinders 152 and 152a are fixed to the upper ends of the fixing members 151 and 151a, And the rod ends of the second cylinders 152 and 152a are hinged to the respective rotary bars 154 as rotary members 153. [

One end of each of the rotation bars 154 is hinged to each rod end of the second cylinders 152 and 152 while being hinged to the lower ends of the fixing members 151 and 151a. The second cutting edge 154 is integrally formed by the second cutting edge 155 which is transversely crossed at the lower end thereof.

The vibrator 160 is installed in the rotary bar 154 to improve the rotating force of the rotary member 153 so that the vibration generated from the vibrator 160 is transmitted to the rotary bar 154 and the second cutting edge 155, the soil friction force of the second cutting edge 155 which is to be rotated in the submerged soil is weakened, so that the rotational force of the second cutting edge 155 can be assisted.

Accordingly, the rotary member 153 including the rotary bars 154 and 154a and the second cutting edge 155 is rotated by a radius of curvature by the rod retraction operation of the second cylinders 152 and 152a, The column is laterally cut as shown in Figs.

After the cutting of the bottom roots and bottom roots of the tree, the rotary member 153 is rotated in a reverse direction by the rod advancing operation of the second cylinders 152 and 152a, As the second cutting edge 155 is positioned, the second cutting edge 155 supports the lower column of the tree, and the hollow 102 formed inside the block 100 holds the wooden column. As a result, when the arm of the excavator is operated upward, the tree is easily pulled out from the buried paper while being supported and fixed by the block body 100.

As such, the curved cutting means 150 can be caused during the transportation of the grafted tree in relation to supporting the lower column of the tree by supporting the grafting of the grafted wood along the turning radius of the second cutting edge 155 It is possible to minimize the occurrence of rocking and clearance, and since the cross section of the landfill is vertical, it is possible to prevent miniaturization of the powder and prevent the powder from being broken.

Hereinafter, the working relationship of the planting apparatus of the present invention to the plant transplanting apparatus will be described in detail below.

First, the arm fastening part 130 fixed to the outer side of the block body 100 is fastened to the arm end part of the excavator.

The block body 100 is moved near the embedding of the target wood for implantation and then the locking induction cylinder 110 of the block body 100 is operated to move the hook 111 caught by the engaging pin 121 Thereby unlocking the open / close blocks 101 and 101a formed in the block body 100. [

Then, by opening the closing and applying cylinders 120 and 120a, the opening and closing of the open / close block 101 and 101a in the closed state is realized by opening and closing outward with respect to the hinge axis.

The fluid is rapidly injected into the elastic tube 170 so as to match the diameter of the wooden column WC that has entered the hollow 102 of the block body 100. As a result, WCs may also be held and bent by an inflation-controlled elastic tube 170.

The fluid to be supplied to the elastic tube 170 is supplied from the hydraulic tank 180 through the injector 190 in an injecting manner. The fluid action relationship in the injector 190 is described in detail in the above- A description thereof will be omitted.

Subsequently, as the linear cutting means 140, the first cylinders 142, 142a, 142b, 142c provided in the respective slide passage pipes 141, 141a, 141b, 141c are operated, And the slide members 143, 143a, 143b, and 143c fixedly coupled to the respective rod ends are also engaged with each other, As shown in Fig.

At this time, the first cutting edges 144, 144a, 144b, and 144c fixedly coupled to the ends of the slide members are linearly moved in a state inclined toward the center point of the hollow 102 while interlocking with each other.

In this process, the first cutting edges penetrate the buried soil in the buried radius of the tree, enter the descending, and easily cut the rooted roots of the buried tree in the inclined vertical direction.

The second cylinder 152 and 152a provided on the fixing members 151 and 151a fixed to the outer sides of the block body 100 are operated as the curved cutting means 150 after the cutting of the cut- As the rods of the cylinders 152 and 152a are operated in the retracting manner, the rotary bars 154 and 154a of the rotary member 153 are curved in the counterclockwise direction and are rotated about the hinge axis axially installed in the fixing members 151 and 151a do.

In this rotation process, the second cutting edge 155 in a state where the rotary bar is connected to the rotary bar 154 and 154a is also interlocked and rotated in a counterclockwise direction. The column under the tree is easily cut in the lateral direction during the rotation process of the tree 155.

The vibrator 160 installed on the rotary bars 154 and 154a serves to offset the frictional force with the soil during the process of the second cutting edge 155 entering the submerged soil to help the rotating force of the rotary member 153 .

That is, when the rotary member 153 rotates, the second cutting edge 155 is rotated in the submerged soil and moved toward the root of the tree. At this time, due to the frictional force between the second cutting edge 155 and the soil, The vibration of the second cutting edge 155 may be restricted so that the vibrator 160 may reduce the friction between the second cutting edge 155 and the soil due to the vibration of the second cutting edge 155, It is possible to contribute to the improvement of the rotational force of the member 153.

As soon as the lower column is cut, the rods 154 and 154a of the rotary member 153 are curved in the clockwise direction as the rods are operated in an advancing manner by the driving of the second cylinders 152 and 152a Reverse rotation.

The second cutting edge 155 interlocked with the reverse rotation of the rotary bar is also reversed and stops the power of the second cylinder 152,152a when the column under the tree is cut, (155) is fixed in a state of being positioned at the cutting position of the lower column.

Accordingly, the second cutting edge 155 becomes a shape supporting the lower column of the tree, and the hollow 102 is structured to hold the wooden column. Therefore, the second cutting edge 155 fully supports the grafted tree, So that the grafted tree can be easily pulled out from the buried paper.

That is, when the arm of the excavator is operated in the upward direction, the block body 100 fastened to the end portion of the rocker is interlocked and operated in the upward direction. In this process, the wooden pillar is held by the hollow 102 of the block body 100 And the bottom of the tree is supported by the second cutting edge 155 formed on the block body 100 can be easily pulled out from the buried floor by the upward movement force of the block body 100. [

As described above, according to the present invention, a cutting apparatus for a tree transplanting machine is characterized in that, in order to transplant trees, the cutting roots of the trees embedded in the soil and, if necessary, the cutting of the bottom posts, It is possible to prevent the damage of the wooden pillar, which is pointed out as a problem in the existing prior arts, so that the transplanted wood can be transplanted into a perfect state.

In addition, the cutting apparatus for a tree transplanting according to the present invention can prevent miniaturization of wood particles caused in the process of culling the grafted trees and breakage of the wood particles caused during transportation of the grafted trees, Therefore, it can contribute to the improvement of the growth of transplanted trees.
