Description

  The present invention relates to a conveying method and apparatus suitable for carrying out felled timber such as bamboo and timber harvested in a mountainous area to a yard.

  In recent years, in order to protect the natural environment, the need for revitalization of satoyama, protection of forests and bamboo forests, revitalization of local forestry, and the use of biomass energy as a countermeasure for the depletion of oil resources has been strongly recognized. As one of the countermeasures, it is requested to cut down excessively thick bamboo and thinning the forest and to make effective use of the thinned wood, but it takes a lot of labor for the work, so it is quite expensive. The reality is that it cannot be done. In particular, it takes a lot of labor and cost to carry out the felled timber to a predetermined collection place.

  Conventionally, a self-propelled gathering machine has been installed at the gathering yard as a device for efficiently transporting felled timber from the previous mountain to the designated gathering yard. A main rope that stretches the main rope, a carriage that is movable along the main rope, and a hook that holds the felling material can be moved up and down on the carriage. A hoisting rope that raises and lowers the tension between the carriage, the tip mountain and the self-propelled gathering machine. A pair of winders that reciprocate the carriage by winding and rewinding operations, and a winder that lifts and lowers the hooks by winding and rewinding the hoisting rope to unload and unload are installed. Is known (for example, see Patent Document 1).

  In addition, a main rope is stretched between Sakiyama and a self-propelled collector installed in the yard, and a carriage that is movable along the main rope is provided. The back rope is stretched between the carriage, the tip mountain, and the self-propelled gathering machine, and a pair of winders that wind and unwind the main rope and the hole back rope are installed in the self-propelled gathering machine. The carriage has a clamping means for clamping the main rope, a winch for winding and lowering a suspension rope for the suspended load by winding the main rope and the hole back rope, and a brake means for braking the winch. In the state where the clamp means is opened and the brake means is braked, the carriage is reciprocated by winding and rewinding the main rope and the hole back rope, the clamp means is operated, and the brake means is Open It is known that the main rope and the hall back rope are wound and unwound in a state where the suspension rope is wound up and down to unload and unload (for example, patents). Reference 2).

In addition, two drums are juxtaposed to the winch device installed in the yard, and the rope is arranged along the loop-shaped route set between the tip and the winch device, and two drums are attached to both ends. The connecting means for connecting the felling material to the rope is fixed, and the rope is reciprocated by selectively rotating the two drums. Is known to reciprocate between the two (see, for example, Patent Document 3).

  However, in the configuration described in Patent Document 1, the main rope supporting the carriage is stretched between the tip mountain and the self-propelled gathering machine, and the main rope, the hole back rope, and the lifting rope are provided. Since it is necessary to provide a mechanism for winding and unwinding the strip, the device configuration of the self-propelled gathering machine and carriage is complicated and the installation work at the site is complicated. However, there is a problem that the cost is high because the work efficiency is low. In addition, since the single carriage is reciprocated when the felled material is carried out, there is a problem that high working efficiency cannot be ensured during the carrying out operation.

  Further, in the configuration described in Patent Document 2, a main rope, a main rope, and a holeback rope are stretched, and a pair of windings that wind and unwind the main rope and the holeback rope in the self-propelled gathering machine. Since the machine is arranged, the lifting rope can be omitted and the structure of the self-propelled gathering machine is simplified compared to the structure described in Patent Document 1, but the structure of the carriage is complicated. Therefore, since the weight is increased, the problem of Patent Document 1 cannot be fundamentally solved.

  Further, in the configuration described in Patent Document 3, the rope is stretched in a loop shape, and the winch device is also a relatively simple device configuration in which two drums are arranged side by side. However, since the connecting means is fixed to the rope, when the logging material is taken out, the rope is reciprocally rotated to move the connecting means back and forth, so that high work efficiency can be ensured during the carrying out work. There is a problem that you can not.

  In view of the above-described conventional problems, the present invention conveys the object to be transported, such as simple equipment configuration and on-site installation work, high carrying-out and carrying work efficiency, and carrying out felled wood with high work efficiency at low cost. It is an object of the present invention to provide a transport method and apparatus that can be applied in the same manner to transport of transport objects in other uses such as in a factory or between buildings.

  In the conveying method of the present invention, the ropes are arranged endlessly between predetermined positions such as the gathering ground and the tip mountain, and the hanging tools are attached to the ropes at appropriate intervals, and the ropes are placed between the predetermined positions. The object to be transported such as felled material is connected to a hanging tool that is rotated in one direction and moves from one position to the other position, and the object to be conveyed is unloaded from the hanging tool at the other position.

  According to this configuration, if it is explained specifically for the removal of felled timber, it will be cut down near the tip of the mountain by a hanging tool attached to an endless rope that rotates in one direction between the yard and the tip. By connecting the timbers and unloading the felled timber from the hanging tool at the yard, the felled timber can be carried out to the yard, and the felled timber can be carried out continuously with high work efficiency. In addition, since it is only necessary to rotate it to a single endless cable equipped with a hanging tool, the equipment configuration and on-site installation work can be performed easily and at low cost, and high work at low cost. Logging can be carried out efficiently.

A cam boss 46 having a cam surface 46a having a number of non-slip protrusions formed on the surface and having a cam surface 46a is rotatably arranged, and an operation plate portion 47 extends from the cam boss 46 along the outer edges of both side plates 44a. In addition, a string-wound spring (not shown) that urges the cam boss 46 to rotate clockwise is provided.

  In the binding belt 40 in which the cam lock buckle 43 is attached to the intermediate portion, the other end 40e of the binding belt 40 is passed between the connecting plates 44b and 44c at both ends of the main body 44 of the cam lock buckle 43 and the operation plate portion 47. Is pressed as shown by the white arrow and pulled out as shown by the arrow between the connecting plate 44c and the cam boss 46, thereby forming a binding space 42 between the connecting plates 44b and 44c. Thus, when the logging material 1 is bound, the operation plate portion 47 is pressed to pull the binding belt 40 back to the binding space 42 side, and a sufficiently large binding space 42 is once formed, and then the binding space 42 is formed. After the felling material 1 is inserted, the operation plate portion 47 is pressed, the other end 40e side of the binding belt 40 is pulled out as shown by the arrow, and the felling material 1 is bound. Locked.

  Further, in the binding belt 40, a ratchet winding buckle 48 as shown in FIG. 11 can be applied in place of the cam lock buckle 43. The ratchet take-up buckle 48 is formed with a slit 50 a through which the other end of the binding belt 40 is inserted into a take-up shaft 50 that is rotatably supported by a main body 49, and the take-up shaft 50 is connected via a ratchet mechanism 51. By connecting the operation lever 52 and reciprocatingly swinging the operation lever 52 as shown by an arrow, the winding shaft 50 is configured to rotate in one direction. Thus, the other end of the binding belt 40 is inserted into the slit 50a of the winding shaft 50 as indicated by the white arrow, and the operating lever 52 is reciprocally swung as indicated by the arrow to wind the binding belt 40 around the winding shaft 50. The felled timber 1 can be bundled. In this state, the operation lever 52 is tilted so as to overlap the main body 49 in a state in which the felled timber 1 is bound, and is locked as it is. Further, when releasing the lock, the ratchet mechanism 51 is released by opening the operation lever 52 to the position of 180 degrees with respect to the main body 49 while pulling the release lever 53, and the winding shaft 50 becomes rotatable. The binding belt 40 can be pulled out.

  Further, in the binding belt 40, a friction lock buckle 54 as shown in FIG. 12 can be applied. The friction lock buckle 54 is provided with a winding shaft 56 on the main body 55 and an operation lever 57 that is rotatable between a position lying on the main body 55 around the winding shaft 56 and a position opened upward. In addition, the operating lever 57 is provided with a winding portion 58. In addition, the main body 55 and the operation lever 57 are provided with an engaged portion 59a and an engagement member 59b that are engaged and locked with each other when the operation lever 57 is laid down, and the engagement member 59b is disengaged. It is configured to be operable. Thus, with the operation lever 57 opened, the other end of the binding belt 40 is passed through the outer side of the winding shaft 56 and the winding part 58 as shown by the white arrow, and then folded back inside the winding part 58. Further, the felling material can be bundled by pulling the bundling belt 40 as it is through the space between the winding shaft 56 and the bundling belt 40 and pulling the bundling belt 40 as it is. Since the binding belt 40 is frictionally fixed by being pressed against each other in a state in which the belt 40 is wound around the winding shaft 56 and the winding portion 58, and the operation lever 57 is locked in this state, the felling material is bound. State is maintained. When releasing the lock, the binding belt 40 can be pulled out by releasing the engaging member 59b and opening the operation lever 57.

  Furthermore, although illustration is omitted as the binding belt 40, a simple endless configuration is applied, and a hook member is applied as the hook 39 at the lower end of the hanging tool 35, so that the binding belt 40 is wrapped around the logging material one or more times. Alternatively, it may be wound a plurality of times, and the end of the binding belt 40 may be hung on a hook member so as to be connected to the hanging tool 35 and the felled material may be conveyed.

  In the above configuration, when thinned wood is felled and carried out in a mountain forest, a gathering field 3 is set in the vicinity of the tip mountain 2 of the target site and close to a road such as a forest road. The track-type self-propelled carriage 4 and the required support roller mechanism 8 are carried in by a truck, etc., the track-type self-propelled carriage 4 is installed in the gathering yard 3, and the rope 6 between the Sakiyama 2 and the gathering place 3 An annular route 6 for arranging the annular route 6 is set, and the support roller mechanism 8 is distributed and arranged at a required position for defining the annular route 6. Next, at a place where the support roller mechanism 8 is arranged, an appropriate standing tree 10 is cut at a height of, for example, about 1.5 m to form the standing tree pile 9, and the mounting bracket 20 of the supporting roller mechanism 8 is attached to each standing tree pile 9. Are fixed and fixed by the restricting means 28 and fixed. Next, an endless cable 6 having a suspension 35 attached thereto is stretched between the drive sheave 5 of the crawler type self-propelled carriage 4 and each support roller mechanism 8 along the annular route 6. As shown in FIG. 1, it is preferable that the standing pile 9 is connected to the adjacent standing tree 10 with a connecting rope 60 as necessary to reinforce its supporting strength.

  When the installation of the logging device 1 is completed in this way, the rotation driving means 11 of the crawler type self-propelled carriage 4 is operated, and the endless rope 6 is moved in one direction between the yard 3 and the tip mountain 2. Rotate. Then, at the tip mountain 2, the felling material 1 is bound by the binding belt 40, and the felling material is applied to the hook 39 at the lower end of the hanging tool 35 that moves toward the collecting place 3 as the rope 6 rotates. The binding belt 40 that binds 1 is connected. Thus, the cutting material 1 can be transported toward the gathering place 3 by turning the rope 6 toward the gathering place 3. At the yard 3, the logging material 1 is unloaded by removing the binding belt 40 from the hanging tool 35, and then the logging material 1 is accumulated at a predetermined location by removing the binding belt 40 and the transportation of the logging material 1 is completed. Then, by repeating the above operation, the felled timber 1 transported to the yard 3 is collected. On the other hand, the binding belt 40 is appropriately returned to the tip mountain 2 by using a hanging tool 35 that circulates and rotates.

  In addition, although the felled timber 1 carried out to the lumber gathering place 3 may be transported as it is to the processing place by a truck or the like, a chopper (not shown) for breaking the felled lumber 1 into chips is installed in the gathering place 3 Then, if the chip material is used for truck transportation, it can be transported efficiently. By the way, the chip of logging material 1 manufactured in this way can be used as a compost, etc. by further drying and pulverizing it, and further adding a fermentation accelerator to the feed of livestock, etc. It can be used effectively as a filler for molded articles, and it can also be regenerated as a substitute for fossil fuels by biological and chemical treatment.

  As described above, according to the present embodiment, the binding belt 40 in which the felled timber 1 is bound in the vicinity of the tip mountain 2 is attached to the hanging tool 35 attached to the endless rope 6 that rotates toward the collecting place 3. By connecting, unloading of the hanging tool 35 and the binding belt 40 at the yard 3 and unloading the felled timber 1, the felled timber 1 can be carried out to the yard 3 and the felled timber 1 is continuous. The work can be carried out with high work efficiency. Moreover, since it is only necessary to rotate the single endless cable 6 equipped with the hanging tool 35, the apparatus configuration and the installation work at the site can be performed easily and at low cost, and the cost can be reduced. The logging material 1 can be carried out with high work efficiency.

  Further, a crawler type self-propelled carriage 4 provided with a drive sheave 5 that can be driven to rotate about a vertical axis is positioned in the gathering place 3, and an annular route 7 set between the gathering place 3 and the tip mountain 2. A support roller mechanism 8 for movably supporting the rope 6 is disposed at an appropriate position, and the endless rope 6 is wound around the drive sheave 5 and the support roller mechanism 8, so that the drive sheave is complicated and large. 5 can be arranged easily and with good workability, and the support roller mechanism 8 can be simply and lightly configured, so that the work of arranging the annular route 7 at an appropriate place can be easily performed with good workability. Therefore, the work of disposing the endless rope 6 over the tip mountain 2 and the collecting place 3 can be easily performed, and the work efficiency of the installation work on the site is remarkably improved.

  In addition, the annular route 7 is set so as to pass through the side portion of the appropriately selected standing tree 10, and the standing roller pile 9 is formed by the selected standing tree 10 to support the supporting roller mechanism 8. Since the mechanism 8 can be supported by using the standing tree 10, it is not necessary to separately drive a column or the like so as to obtain a required support strength, so that workability is further improved.

  In addition, a suspension belt 35 in which a hanging tool 35 is wound around the rope 6 in an inverted U shape, a sheath member 37 through which the suspension belt 36 hangs down from the rope 6, and the sheath member 37 are directed to the rope 6. A fixing tool 38 that fixes the suspension belt 36 to each other at the lower end of the sheath member 37 in a state of being pushed up, and a hooking tool 39 provided at the tip of the suspension belt 36 that extends downward from the fixing tool 38. Since the hanging tool 35 is mainly constituted by the hanging belt 36 wound around the rope 6 in an inverted U-shape, even when the hanging tool 35 is mounted on the rope 6, it does not protrude greatly from the outer surface of the rope 6. In addition, since it has the same properties as the rope 6, it can be easily and reliably supported by the drive sheave 5 and the support roller mechanism 8 so as to be driven and movable. Moreover, since the hanging portion of the suspension belt 36 from the rope 6 is constrained by the sheath member 37, there is no risk that the suspension belt 36 will be greatly bent and caught on the peripheral members, and the rope 6 can be stably rotated. Can be secured. Moreover, since the hooking tool 39 is provided at the lower end of the hanging belt 36, the binding belt 40 holding the felled material 1 can be easily connected by being hooked on the hooking tool 39 to be transported and unloaded.

  The support roller mechanism 8 includes at least a lower support roller 13 that supports the rope 6 from below, a lateral support roller 14 that supports the rope 6 in the left-right direction, and an upper support roller 17 that presses the rope 6 from above. The roller units 15, 18, 19 having any one of them and the mounting bracket 20 having the roller units 15, 18, 19 arranged at the upper part are fixed, and the lower part of the mounting bracket 20 is fixed to the standing pile 9. Therefore, the support roller mechanism 8 can be disposed using a standing tree, and the driving post and the driving operation thereof are not required. Therefore, the supporting roller can be disposed with good workability and the cost is reduced. Can be achieved. Further, since the roller units 15, 18, and 19 have at least one of the lower support roller 13, the lateral support roller 14, and the upper support roller 17, the rope 6 at the location where the support roller mechanism 8 is disposed. It can be supported appropriately according to the tension situation.

  Further, the lower support roller 13 is composed of divided drum-type rollers 23a and 23b which are divided into two so as to support the rope 6 from both lower sides and to form a hanging tool passage space 24 in the middle. In a state where the hanging tool 35 is suspended from the strip 6, the strip 6 can be surely supported so as to be freely passed from both sides of the lower portion, and from below the strip 6 in a state where the hanging device 36 is attached to the strip 6. Can be reliably supported. Further, the lateral support roller 14 moves and urges the pair of grooved rollers 61a and 61b having annular concave grooves in which the strips 6 fit on the outer periphery, and the other grooved roller 61b toward the one grooved roller 61a. Since the moving urging means 63 is provided, by restricting the rope 6 from both sides, the rope 6 can be reliably prevented from being shaken laterally or displaced during rotation, thereby stabilizing the rope 6. The rotated state can be ensured.

  Although the example which applied the synthetic resin fiber rope which consists of a synthetic resin fiber was shown as the rope 6 in the above embodiment, a wire rope, a chain, etc. can also be applied. However, wire ropes, chains, etc. are heavy and require a lot of labor for tensioning work, and if they are heavy, they droop down greatly, so it is necessary to apply a large tension during operation, which makes the equipment configuration itself large. There is a problem that the cost becomes high. On the other hand, if a synthetic resin fiber rope is used, it is preferable because the required strength can be ensured while being lightweight.

  FIGS. 13 to 15 show another vertical bending roller unit 18 different from the above. This has a bifurcated roller bracket 25 fixed to the inner edge of a gate-shaped mounting plate 21 that is mounted and supported on a mounting bracket or the like, and the divided drum-shaped rollers 23 a and 23 b are horizontally disposed on both side plates of the roller bracket 25. It is provided so that it can rotate around an axial center, and the rope 6 passed as shown in FIGS. 13-16 is supported from the bottom. The upper and lower portions of the roller bracket 25 are provided with upper roller brackets 25a and 25b extending in the longitudinal direction of the rope 6 and between these, upstream and downstream ends of the lower roller brackets 25a and 25b, A pair of vertical cylindrical rollers 26a and 26b, which are rotatable around a vertical axis disposed so as to sandwich the cord 6 from both sides at upstream and downstream positions of the divided drum rollers 23a and 23b, are attached. As a result, the rope 6 is supported from below by the divided drum rollers 23a and 23b and can travel stably without coming off from the pair of divided drum rollers 23a and 23b, as shown in FIG. Even if it becomes a vertically bent state facing downward in one or both of the upstream and downstream sides of the mold rollers 23a and 23b, the split drum rollers 23a and 23b are not separated from each other, and more stable running is achieved only by increasing the contact angle. it can. However, as shown in FIG. 13, the cord 6 becomes more disengaged upward from the divided drum rollers 23 a and 23 b so as to be bent vertically from the horizontal to the divided drum rollers 23 a and 23 b. In order to prevent this, a horizontal cylindrical roller that is rotatable about the horizontal axis between the upstream and downstream ends of a pair of roller brackets 25c extending from both side plates of the roller bracket 25 to the upstream side and the downstream side. 27 so that the strip 6 is in contact with the divided drum rollers 23a and 23b in a horizontal state in the range from the vicinity of the upstream side to the vicinity of the downstream side with the contact portion with the divided drum rollers 23a and 23b as a boundary. The cord 6 is prevented from coming off from the divided drum rollers 23a and 23b.

  Although the cord 6 travels while being supported by the divided drum rollers 23a and 23b from below, there is no catch when the hanging tool 35 having a large passage width passes as shown in FIG. As shown in 16 (b), it is necessary not to fall into the suspension passage 24 when the rope 6 having a small passage width passes alone.

  In addition, as shown in FIG. 17, the suspending tool 35 wraps a suspension belt 36 around the rope 6 in an inverted U shape, and the suspension belt 36 suspended from the rope 6 forms a flat rectangular tube-shaped sheath member 37. Then, the sheath member 37 is pushed up toward the rope 6 and the suspension belt 36 is fixed to the sheath member 37 at the lower end of the sheath member 37 with the fixture 38 described above. It is combined. The hook 39 is attached to the suspension belt 36 that is suspended downward from the fixture 38 by a predetermined length. In this example, the suspension belt 36 is particularly connected to one end of the length adjusting buckle 43 described above. The extended end side that extends from the connecting portion between the fixed portion 36c and the other end of the buckle 43 and passes through the connecting hole 39b of the hook 39 is folded back to the buckle 43 side. The length can be adjusted by releasing or loosening the pressure contact of the lock member 43b by passing between the main body 43a and the lock member 43b elastically pressed against the main body 43a by the bias of the spring 43c and the like. It is assumed that a length adjusting portion 36d that is locked to the adjustment length by press contact is provided.

  Thereby, it is convenient to unload and unload the felled timber 1 that is bound and supported by the binding belt 40 hooked on the hook 39 only by adjusting the length of the length adjusting portion 36d. Therefore, as shown in FIG. 17, the hanging tool 35 is provided with a loop-like binding belt 40 that is hooked and connected to the hook 39, and the hook 39 has a check lever 39c that opens on the receiving side and closes on the releasing side. If the hook is supported by hooking the upper end portion of the loop-like binding belt 40 whose lower end is wound around the felling 1, it is instantly possible to remove the binding belt 40 from the hook after unloading. This is possible, and it is even easier to hook the binding belt 40. In addition, if the unloading is released or loosened by the locking member 43c of the buckle 43, the felling material 1 descends while extending the folded portion of the length adjusting portion 36c of the hanging belt 36 downward by its own weight. The amount of unloading can be reduced. The descent speed during unloading can be saved by gripping the extended end of the length adjusting portion 36c and applying a force to the pulling side. Further, if the extended end of the length adjusting portion 36c is grasped and pulled down, the felled material 1 can be lifted and unloaded while shortening the length of the two-folded portion. At this time, if the locking force of the locking member 43c acts strongly on the unloading side and slides or loosens on the unloading side, unloading can be safely performed without unlocking or loosening the locking member 43c. . Further, the loop-like binding belt 40 is convenient in that the lower end side of the felling material 1 can be bundled so as not to slip and fall naturally by the weight of the felling material 1 when it is unloaded to the felling material 1 and loaded.

  Further, as shown in FIGS. 18 and 19, the drive sheave 5 described above is mounted on the boom 4b of the crawler type self-propelled carriage 4 via the angle adjusting means 4d of the rotating shaft 4c, and the arm 4e connected to the boom 4b. The excavator 4f, blade, and other tip work tools and the drive sheave 5 can be switched and connected to a hydraulic drive source (not shown) by a switching lever 4g. In the case of the illustrated example, the angle adjusting means 4d includes a base 71 fixed on the boom 4b by welding or bolting and a rotation mechanism 72 of the drive sheave 5 from the rotation axis to one side in the front-rear direction with respect to the rotation shaft 4c. It is assumed that the horizontal shaft 73 located at a side is connected by a jack type lifting mechanism 74 with screws or the like on the other side, and the rotating shaft 4c is tilted forward and rearward around the horizontal shaft 73 by the lifting operation of the lifting mechanism 74. It can be tilted. As a result, the crawler type self-propelled carriage 4 can be stably fixed by obtaining the anchor effect by the excavator 4f or the like regardless of whether it is a flat land, an inclined land, or a bumpy land, and at what angle the boom 4b is in this stable posture. However, the rotation shaft 4c of the drive sheave 5 can be adjusted to be perpendicular to the direction in which the strip 6 is wound around the drive sheave 5, and the strip 6 can be driven without a special guide. There will be no departure.

  As shown in FIGS. 18 and 19, the drive sheave 5 of this example is provided with a flange-shaped or ring-shaped guide 75 having an outer diameter larger than that of the fixed sheave 5 at the lower portion, and the rope 6 around the drive sheave 5. 9 is lifted obliquely by the guide 75 via the sheath member 37 shown in FIG. 9, or directly acts on the suspension belt 36 without the sheath member 37 as shown in FIG. They are pulled apart to prevent interference with the drive sheave 5, the boom 4b, and the base 71 side.

  Further, if the rotation mechanism 72 employs a hydraulic drive mechanism for the drive shaft disposed at one end of the crawler belt and the fixed sheave 5 is connected to the drive shaft, the existing drive pipe is connected to the crawler self-propelled carriage 4. Only by using the self-propelled function according to the lever operation of the crawler-type self-propelled cart 4 can be driven forward and reverse, and the necessary strength can be sufficiently obtained.

  Furthermore, as shown in FIG. 20, the rope 6 can be connected to each other without loss of the degree of freedom of bending and twisting by means of a universal connection fitting 81. This may be between the ends of one ridge 6 or between the ends of individual ridges 8. If the ends of the individual ropes 8 are connected to each other, the required length of the route length can be obtained by connecting the necessary number of the ropes 6 that have already been formed on a regular scale.

  In particular, when the bifurcated connecting bracket 82 is connected in advance to the end portion of the rope 6 and the bifurcated coupling bracket 82 can be connected to the site by the hinge pin 84 via the cross-connecting bracket 83, it is convenient for handling the rope 6. is there. Further, if the connection is made between the individual cords 6, it is particularly convenient to extend the cord 6 toward the required route length at the site. In these cases, if the end of the rope 6 is folded after passing through the connecting hole 82a of the bifurcated fitting 82 as shown in the drawing, it cannot be caught if it is knitted or relieved in the original rope 6. Easy to run. As shown in the figure, the braided portion and the braided portion are thick, but do not become a catching portion, and are suitable because they are within the same bulkiness as the connection fitting 81. The rope in the illustrated example is the rope described above and adopts a braided structure. In addition, since the braided part or the base part of the rope 6 is thicker than others and tends to be damaged, it is preferable to protect it by covering it with a shrink film 91 as indicated by a virtual line in FIG.

  Furthermore, the suspension belt 36 shown in FIG. 21 is a simplified type in which the sheath member 37 is omitted as described above, and the state in which the suspension belt 36 is folded and hung on the rope 6 is held by the fixture 38. The implementation system is shown. Also by this, the felling material 1 by the suspension belt 36 can be conveyed stably. The hooking portion of the suspension belt 36 on the rope 6 is loosened to some extent when the felling material 1 is not supported, but when the felling material 1 is supported, as shown in FIG. However, it is preferable to provide an anti-slip on the rope 6 in order to prevent displacement when loosened. Although the slip stopper can be used in any way, in the example shown in the drawing, the binding band 92 with a resin stopper is installed at two places before and after the suspension belt 36 mounting portion of the rope 6 in the transport direction from the width of the suspension belt 36. Are also installed at slightly larger intervals. By tying the binding band 92 around the rope 6 so as not to be displaced, the displacement of the suspension belt 36 can be reliably prevented, and the suspension belt 36 is displaced downstream in the moving direction of the rope 6. Although it shows a tendency, the binding band 92 on the corresponding side receives it and prevents further displacement. Therefore, the distance between the suspension belts 36 on the rope 6 hardly changes, and it is possible to avoid the fact that the felling materials and the like being conveyed are intertwined with each other.

  The present invention connects a logging device near the tip mountain to a hanging tool attached to an endless rope that rotates in one direction between the logging site and the tip mountain, and logs from the hanging tool at the tagging site. By unloading the timber, the felled timber can be carried out continuously to the yard with high work efficiency, and it is only necessary to rotate it to a single endless cable with a hanging tool. Since the apparatus configuration and the installation work at the site are simple and the felled wood can be carried out at low cost and with high work efficiency, it can be suitably applied to carry out felled wood such as bamboo and wood.
