[0005]
[Problems to be solved by the invention]
In the above prior art, the wood to be crushed is conveyed by an endless chain belt and introduced into the crushing device, but the chain belt that has been introduced is driven by a driving wheel located at the crushing device side end of the guide conveyor. After wrapping around downward, it returns to the driven wheel located at the end opposite to the crushing device. At this time, some pieces of wood (chips) that have been conveyed to be introduced into the crushing device may go down without being introduced into the crushing device while being caught by the chain belt. In this case, the piece of wood or the like separates from the chain belt while returning to the driven wheel. Then, since the hopper has a bottomless shape, the hopper spills to the ground, and accumulates while scattered below the guide conveyer around the lower part of the crusher with the elapse of the operation time.
[0006]
In view of this point, the inventors of the present invention have invented a hopper configuration having a bottom, which includes a side wall provided on both sides in the width direction of the guide conveyor and a bottom wall provided below the guide conveyor. With this, even if some pieces of wood or the like are wrapped down while being hooked on the chain belt during the crushing operation, they are guided to the outside of one end (front end) of the hopper by the bottom wall of the hopper. Since the pieces are concentrated and discharged, it is possible to prevent the pieces of wood from being scattered below the guide conveyor.
[0007]
However, depending on the crushing site, there is a strong demand not to spill the wood piece itself to the ground from the viewpoint of environmental hygiene and the like, and the above configuration cannot sufficiently meet the demand.
[0008]
The present invention has been made in view of the above problems, and an object of the present invention is to prevent a piece of wood from spilling to the ground during crushing work, and to easily perform wood piece cleaning at the end of crushing work. It is an object of the present invention to provide a capable wood crusher.
[0009]
[Means for Solving the Problems]
(1) In order to achieve the above object, the present invention provides a body frame, a crushing device provided on the body frame, and a driving wheel, a driven wheel, and a driving wheel provided on one longitudinal side of the body frame. A transporting means for transporting the crushed wood to the crushing device, the transporting means having an endless transporting body wound and circulated around a wheel and a driven wheel, and a width of the transporting means so as to surround the transporting means. A bottomed hopper comprising a side wall provided on both sides in the direction, a front wall provided on the front side of the transporting means, and a bottom wall provided below the transporting means and having an opening below the driving wheel. And a first opening / closing door that covers an opening of the bottom wall.
[0010]
In the present invention, the hopper is provided on a side wall provided on both sides in the width direction of the conveying means, a front wall provided on the front side of the conveying means, and provided below the conveying means, and has an opening at a position below the driving wheel. In addition to a bottomed hopper having a bottom wall having the same, a transporting means including a driving wheel, a driven wheel, and an endless transporting body is disposed so as to be surrounded by the bottomed hopper. As a result, during the crushing operation, some pieces of wood go down while being hooked on the carrier, and the pieces of wood are guided by the bottom wall of the hopper to one end (front end) of the hopper. At this time, in the present invention, since the bottomed hopper has the front wall body on the front side of the conveying means, the guided wood piece is blocked by the front wall body, so that the wood piece is guided from inside the hopper to the outside. It is not emitted. Therefore, it is possible to improve environmental hygiene in accordance with a demand that the wood pieces themselves should not be spilled on the ground.
[0011]
However, as a result of preventing the pieces of wood from spilling out of the hopper as described above, the pieces of wood gradually accumulate in the hopper. For example, it is necessary to perform cleaning after the crushing operation is completed. Therefore, in the present invention, at the time of this cleaning, the wood staying in the hopper is transported by the transport means (for example, the wood staying in the hopper crusher side is transported by rotating the transport means forward, and the hopper What is retained on the opposite side is transported by reversing the transporting means) and opening the first opening / closing door covering the opening at the lower position of the drive wheel in the hopper bottom wall, so that the discharge is concentrated from the opening. Can be done. As a result, for example, the dropped wood can be received by a carry-out conveyor provided at the lower part of the crusher for carrying out the crushed material, and can be carried out to the outside of the other side of the main body frame. Timber can be sorted and sorted by receiving it in the bucket of the traveling transport machine and transporting it to a predetermined position, or by shifting the loading and unloading position by the unloading conveyor during crushing work and the unloading loading position during cleaning. Can be loaded. As described above, after the crushing operation is completed, the cleaning operation can be easily performed by collecting the remaining wood pieces and discharging the collected pieces of wood from the opening / closing door by using the transfer function of the transfer unit.
[0012]
(2) In the above (1), preferably, an opening is provided at a position below the driven wheel on the bottom wall, and a second opening / closing door is provided to cover the opening.
[0013]
Thereby, at the time of cleaning after the crushing operation is completed, for example, what has stayed on the opposite side of the crushing device in the hopper is transported by reversing the transporting means, and the opening at the position below the driven wheel in the hopper bottom wall body. By opening the second opening / closing door that covers the device, the device can be dropped from the opening. Thereby, for example, the dropped wood can be received and accumulated by the receiving means. Further, when a predetermined amount is accumulated, it can be removed and transported to another place.
[0014]
(3) In the above (1) or (2), preferably, a rotating roller is provided on the upper portion of the front wall.
[0015]
A bottomed hopper comprising a side wall provided on both sides in the width direction of the transporting means, a front wall provided on the front side of the transporting means, and a bottom wall provided below the transporting means as described in (1) above. In this case, the pieces of wood or the like wrapped around on the drive wheel side of the transport means are transported toward the driven wheel side by the endless transport body at the lower part of the hopper, and are stored in the space between the front wall body and here. When a certain amount is accumulated, it is placed again on the upper part of the transporting body and transported again to the crushing device side. In order for such a re-transport function to work effectively, the height of the front wall must be somewhat higher than the transport surface by the transport means (otherwise, a lower front wall is required before re-transport). It overflows from the body and spills out of the hopper.) As a result, at the time of crushing work, when relatively long wood to be crushed (such as one longer than the longitudinal dimension of the hopper) is thrown into the hopper, one end of the wood interferes with the high front wall body and is caught by friction, There is a possibility that smooth conveyance by the conveyance means may be hindered.
[0016]
Therefore, in the present invention, by providing a rotating roller on the upper part of the front wall, it is possible to eliminate the snagging due to the above-mentioned interference and to smoothly carry by the carrying means.
[0017]
(4) In any one of the above (1) to (3), preferably, the wood crusher is provided with an unloading conveyor for unloading crushed crushed wood, and a traveling means, and is capable of self-propelling.
[0018]
(5) In order to achieve the above object, according to the wood processing method of the present invention, a transporting means in which crushed wood is thrown into a bottomed hopper provided on one side of a main body frame and stored and arranged in the hopper The crushed wood is conveyed to the crushing device side to be crushed, and the crushed wood is conveyed out of the other side of the main body frame by an unloading conveyor, loaded at a predetermined position, and then the wood pieces staying in the hopper are conveyed. While being conveyed by means, the hopper is dropped from an opening provided at a position below a driving wheel on the side of the crushing device of the conveying means in the bottom wall of the hopper, and the dropped wood is received by the carry-out conveyor, and The wood is carried out to the outside of the other side of the frame, and the carried wood is received by a bucket of a self-propelled carrier machine and carried.
[0019]
(6) In order to achieve the above object, according to the wood processing method of the present invention, there is provided a conveying means in which wood to be crushed is put into a bottomed hopper provided on one side of a main body frame and stored and arranged in the hopper. After being transported to the crushing device side and crushed, the crushed wood is carried out to the outside of the other side of the main body frame by a carry-out conveyor and loaded at a predetermined position, and the arrangement or direction of the wood crusher is shifted, While transporting the piece of wood staying in the hopper by the transporting means, the piece of wood was dropped from an opening provided below a driving wheel of the transporting means on the side of the crushing device of the transporting means, and dropped. The timber is received by the carry-out conveyor and carried out, and is loaded at a position different from the carry-out position before the arrangement or the direction is shifted.
[0020]
(7) In order to achieve the above object, according to the wood processing method of the present invention, a transporting means in which crushed wood is thrown into a bottomed hopper provided on one side of a main body frame and stored and arranged in the hopper The crushed wood is conveyed to the crushing device side to be crushed, and the crushed wood is conveyed out of the other side of the main body frame by an unloading conveyor, loaded at a predetermined position, and then the wood pieces staying in the hopper are conveyed. While being conveyed by the means, the hopper is dropped from an opening provided below the driven wheel on the opposite side of the crushing device of the conveying means from the bottom wall of the hopper, and the dropped wood is received by the receiving means.

And a concave portion (a cutout portion) 29c. As will be described later, a handle (not shown) or the like may be provided for convenience in inserting and removing the sieve member 29 in the axial direction of the crushing rotor 20.
[0033]
FIG. 8A is a plan view of the support member 30 as viewed from above (in the direction VIIIA in FIG. 5), and FIG. 8B is a plan view of the support member 30 taken along the line VIIIB in FIG. It is the arrow side view seen from the direction.
[0034]
8 (a) and 8 (b), the support member 30 is used for positioning for engaging with the curved frame portions 30b1 and 30b2, the straight frame portion 30a, and the cutout portion 29c of the sieve member 29. And a convex portion (protruding portion) 30c that forms the engaging portion (first engaging portion) of (a).
[0035]
The curved frame portions 30b1 and 30b2 are bent at appropriate positions (five in the present embodiment) in the axial direction of the crushing rotor 20 along the sieve member 29 in the circumferential direction of the crushing rotor 20. Among these curved frame portions 30b1 and 30b2, the curved frame portion 30b2 is a bracket 30b2B provided with a through hole 30b2A at an end on the front side (left side in FIGS. 8A and 8B) of the self-propelled wood crusher. A bracket 30b2D provided with a through-hole 30b2C at the rear end (right side in FIGS. 8A and 8B) of the self-propelled wood crusher is fixed in a substantially horizontal direction by, for example, welding. Is what it is. 30b1 is not provided with these brackets.
[0036]
In this embodiment, curved frame portions 30b1 are provided at both ends and at the center of the support member 30 in the axial direction of the crushing rotor 20 (the vertical direction in FIG. 8A or the vertical direction in FIG. 8B). Further, the curved frame portions 30b2 are disposed at approximately two central portions between the three curved frame portions 30b1.
[0037]
The straight frame portion 30a is a sieve member in the axial direction of the crushing rotor 20 (vertical direction in FIG. 8A or perpendicular to the paper surface in FIG. 8B) so as to be substantially orthogonal to the curved frame portions 30b1 and 30b2. It is appropriately extended at several places (three places in the present embodiment) along 29.
[0038]
FIG. 9 is a perspective explanatory view showing a state where the sieving member 29 is placed on the support member 30 having the above-described structure (a part of the detailed structure is not shown). As shown in FIG. 9, in the present embodiment, two sieve members 29 each having a substantially partial cylindrical shape are placed so that the outer peripheral side thereof is along the inner peripheral side of the support member 30. At this time, one of the features of the present embodiment is that the convex portion 30c of the support member 30 is sandwiched between the two sieve members 29, 29, and cuts provided at the four corners of each support member 30. The notches 29c of the notches 29c on the side of the protrusions 30c are respectively engaged so as to face the protrusions 30c, thereby restricting the circumferential movement of each support member 30 due to its own weight.
[0039]
In this example, the convex portions 30c are provided only on the curved frame portions 30b1 at both ends of the support member 30. However, the present invention is not limited to this, and the convex portions 30c are also provided on the middle curved frame portion 30b1 (corresponding to the sieve member 29). Needless to say, a concave portion 29c is provided in a portion where the above-mentioned operation is performed. Alternatively, it is also conceivable to provide the convex portion 30c only on the middle curved frame portion 30b1.
[0040]
Also, as described above, instead of providing the convex portion 30c in a portion corresponding to the position where the two sieve members 29 are adjacent to each other in the curved frame portion 30b1, the convex portion 30c is provided at the center in the circumferential direction of each sieve member 29 and the crushing rotor 20 shaft. The projections 30c may be provided at a total of two places at both ends in the direction. In this case, it is sufficient to provide only two concave portions 29c in each of the sieve members 29, and the number can be reduced as compared with the case where the sieve members are provided at the four corners described above.
[0041]
Further, in the above description, the case where the convex portion is provided on the support member 30 side and the concave portion is provided on the sieve member 29 side and these are engaged with each other has been described as an example. Conversely, the concave portion is provided on the support member 30 side. Alternatively, a projection may be provided on the sieve member 29 side. In addition, the shape is not limited to the uneven shape. In short, it suffices that the support member 30 side and the sieve member 29 side can be engaged with each other for alignment by some shape or structure.
[0042]
Returning to FIG. 5, a side wall 32 is erected on a crusher attachment portion 10 </ b> A of the main body frame via a steel material 31.

At this time, a middle plate 15c and steel materials 31a, 31b are extended between the side plates 15b, 15b with the longitudinal direction being substantially horizontal, and the steel materials 31a, 31b are extended behind the self-propelled wood crusher of the crushing rotor 20. The nut 15c2 is welded, and the bracket 130 is installed via the bolt 15c1. A gantry 35 is provided between the side plates 15b, 15b and on the steel material 31b (not shown). The gantry 35 includes an upper surface portion 35a installed substantially horizontally, and a reinforcing plate 35c installed perpendicular to the upper surface portion 35a.
[0044]
Hanging bolts 36, 36 are provided on the gantry upper surface 35b at positions corresponding to the support member brackets 30b2D, 30b2D in the width direction of the self-propelled wood crusher (perpendicular to the plane of FIG. 5). The self-propelled wood crusher is suspended by 37 and 37 so that it can swing in the front-rear direction. The support mechanism 37 includes a support member 37a for supporting the hanging bolt 36 rotatably clockwise and counterclockwise, and pins 37b, 37b protruding from the support member 37a on both sides in the width direction of the self-propelled wood crusher. The frame 37 is composed of, for example, a U-shaped left / right mount 37c which supports the pins 37b, 37b with respect to the mount upper surface 35b.
[0045]
At this time, 38, 38 are columnar shafts provided with threaded holes 38a, 38a in a direction perpendicular to the axial direction, and the threaded holes 38a, 38a are screwed with the suspension bolts 36, 36. (See FIG. 8A). The shafts 38, 38 are inserted into the through holes of the brackets 30b2D, 30b2D of the support member 30 described above, so that the shaft 38 moves the suspension bolt 36 and the support member 30 relative to each other. Are combined while allowing.
[0046]
With the above-described structure, the support member 30, the bracket 33, the hanging bolts 36, the support mechanism 37, and the shaft 38 constitute a moving mechanism 120 for moving the sieve member 29 to the vicinity of the opening 15bA. Will be described later.
[0047]
On the other hand, an anvil (secondary crush plate, repulsion plate) 27 as a fixed blade is provided above the sieving member 29 and the support member 30 in the outer peripheral region of the crush outer diameter formed by the rotation locus of the crush bit. A fixed blade support 82 is provided. The fixed blade support 82 is provided near the uppermost portion (upper portion) of the crushing rotor 20 above the fixed portion 82A and a fixed portion 82A fixed to the base portion 15 as a fixed side member. And a rotating portion 82B rotatable by a pin 84 having the horizontal direction as the axial direction. In this example, three anvils 27a, 27b, and 27c are arranged in this example from the upstream side in the rotation direction of the crushing rotor 20, and the anvil 27a is fixed to the rotating portion 82B, and the anvils 27b and 27c are fixed. It is provided in the portion 82A.
[0048]
At this time, at the upper end of the rotating portion 82B on the fixed portion 82A side and at the upper end of the fixed portion 82A on the rotating portion 82B side, sheer pin support portions 85 and 86 are provided so as to face each other. A sheer pin 87 is provided so as to bridge between the sheer pin support portions 85 and 86. The shear pin 87 is of a known type having a stress concentration portion formed of, for example, a notch. The above-described rotating portion 82B is arranged so as to be freely rotatable around the pin 84, and is held stationary only by being connected to the fixed portion 82A via the shear pin 87. As a result, when an excessive force in the direction along the crushing rotor 20 acts on the anvil 27a disposed in the rotating portion 82B and an excessive stress that can be withstood by the stress concentration portion of the shear pin 87 is generated, 5, the pivot portion 82B pivots so as to retract around the pin 84 in the direction A in FIG. 5 (in other words, the direction along the rotation direction of the crushing rotor 20), and the opening portion is located at this position. Is created.
[0049]
Here, a known contact-type limit switch (not shown) is provided on the shear pin support portion 86 provided on the fixed portion 82A side as a means for detecting the rotation of the rotation portion 82B.

Returning to FIG. 1, the discharge conveyor 7 has a discharge side (rear side of the self-propelled wood crusher, the right side in FIGS. 1 and 2) having an arm member 99 projecting from the power unit 9 and a support member 98 a. , 98b. The portion on the opposite side of the discharge (the front side, the left side in FIGS. 1 and 2) is located below the main body frame crusher attachment portion 10A, and is suspended from the main body frame crusher attachment portion 10A via the support member 97. It is supported as follows. As a result, the unloading conveyor 7 is inclined upward from the lower part of the main body frame 10 to the outside of the main body frame 10 to the rear side of the self-propelled wood crusher (outward of the crusher main body 5) through the lower part of the power unit 9. Are located. Reference numeral 96 denotes a frame. Reference numeral 95 denotes a drive wheel supported by the frame 96. Reference numeral 94 denotes an unloading conveyor hydraulic motor (see FIG. 2) for driving the drive wheel 95. Reference numeral 89 denotes a drive wheel 95 and a driven wheel (not shown). And a conveyer belt wound between them.
[0103]
The power unit 9 is mounted on an upper part of the rear end (right side in FIGS. 1 and 2) of the self-propelled wood crusher of the main body frame crusher mounting portion 10A via a power unit loading member 81, A driver's seat 9A is provided on the front side.
[0104]
Next, the operation of the self-propelled crusher according to the present embodiment having the above configuration will be described below.
[0105]
When crushed wood (such as crushed wood) is loaded into the hopper 2 by an appropriate working tool such as a grapple of a hydraulic shovel, the crushed wood received by the hopper 2 is placed on the carrier 41 of the feed conveyor 3. While being guided by the side wall 2b of the hopper 2, the conveyer 41 conveys in a substantially horizontal direction to the rear side of the self-propelled wood crusher (right side in FIGS. 1 and 2).
[0106]
When the crushed wood conveyed backward in this way reaches near the front end (the left end in FIGS. 1 and 2) of the pressing conveyor device 5, the upper portion of the crushed wood becomes the endless track member of the pressing conveyor device 5. The pressing conveyor device 5 is lifted up so as to enter the lower part of the container. The upper portion is pressed down by the weight of the pressing conveyor device 5 to be pressed and gripped, and the rear side (right side in FIGS. 1 and 2) is held while being held in cooperation with the feed conveyor 3 with the rotation of the endless track member 56. ) And is introduced into the crushing device 16. In this way, the wood to be crushed can be smoothly and efficiently introduced into the crushing device 16.
[0107]
When the wood to be crushed is introduced into the crushing device 16, the pressing roller 54 at the end of the pressing conveyor device 5 on the side of the crushing device 16 and the feed roller 39 at the end of the feed conveyor 3 on the side of the crushing device 16 cooperate. The crushed wood is sandwiched from above and below, and the tip of the crushed wood on the side of the crushing device 16 is protruded in a cantilever manner toward the crushing rotor 20 while the sandwiched portion is used as a fulcrum for crushing. Then, the crushing bit 18 of the rotating crushing rotor 20 collides with the protruding tip, thereby relatively roughly folding or crushing the tip of the crushed wood (primary crushing, pre-crushing). The broken tip of the crushed wood is guided in the space on the outer peripheral side of the crushing rotor 20 along the rotation direction of the crushing rotor 20, and sequentially collides with the anvils 27a, 27b, 27c and is further finely crushed by the impact force. (Secondary crushing, main crushing).
[0108]
The crushed wood that has been crushed as described above rotates around the space (crushed wood flow passage) on the outer peripheral side of the crushing rotor 20 until it has a particle size that can pass through the opening of the sieving member 29, The impact force is further applied by 27a to 27c to be crushed. When the particle size becomes small enough to pass through the mesh of the sieve member 29, it is sorted through the mesh of the sieve and discharged to the outside of the sieve member 29.
[0109]
The discharged crushed wood falls onto a conveyor belt 89 of the unloading conveyor 7 via a chute (not shown). The unloading conveyor 7 transports the above-mentioned crushed wood to the rear side (the right side in FIGS. 1 and 2) by the circulatingly driven conveyor belt 89, and finally the crushed wood outside the crusher main body 5 (self-propelled wood crusher). (The right end in FIG. 1) as a recycled product.
[0110]
As described above, the pressing roller 54 at the end of the crushing device 16 of the pressing conveyor device 5 and the feed roller 39 at the end of the crushing device 16 of the feed conveyor 3 move the tip of the crushed wood toward the crushing rotor 20. When the crushing operation is carried out by projecting the crushed wood into the cantilever shape, the transport body 41 in which the crushed wood has been introduced is turned downward by the driving roller 39 and then driven by the driven roller 40 in the reverse direction. Return to the side (see FIG. 23). At this time, some pieces of wood (chips) that have been transported to be introduced into the crushing device 16 may go down without being introduced into the crushing device 16 while being caught by the transport body 41. . In response to this, in the present embodiment, the hopper 2 has a bottomed shape including a front wall 2a, side walls 2b and 2b, and a bottom wall 2d, and the entire feed conveyor 3 has the bottomed shape. The hopper 2 is housed and arranged. As a result, even if some pieces of wood or the like go down while being caught on the carrier 41 during the crushing operation as described above, they are guided to the front end of the hopper 2 by the hopper bottom wall 2d. Since the guided wood pieces are blocked by the front wall 2a, they are not discharged from the hopper 2 to the outside. Therefore, it is possible to improve environmental hygiene in accordance with a demand that the wood pieces themselves should not be spilled on the ground.
[0111]
Here, as a result of preventing the pieces of wood from spilling out of the hopper as described above, the pieces of wood are removed from the transport body 41 when the transport body 41 is turned upward along the rotation direction of the driven roller 40. It is separated and is stored in the space P between the driven roller 40 and the front wall 2a. Then, when a certain amount is accumulated here (for example, when the pile is accumulated to a height substantially equal to the upper surface position of the transport body 41 corresponding to the upper end position of the driven roller 40 in the radial direction), it is mounted again on the transport body 41, It is transported again to the crushing device 16 side.
[0112]
As described above, if a certain amount does not accumulate in the space P between the driven roller 40 and the front wall 2a as described above, a piece of wood is not re-transported to the crushing device 16 side. The amount of wood pieces will always remain in the hopper 2. If the above-mentioned remaining wood pieces are left in the hopper 2 as they are after the crushing operation, there is a possibility that they may freeze in the nighttime in winter and it may be difficult to restart the next morning. For this reason, it is usually necessary to clean the piece of wood remaining in each part (the space P and other parts) in the hopper 2 each time the crushing operation is completed.
[0113]
In the present embodiment, at the time of cleaning after the end of the crushing operation, for example, the first opening / closing door 47 provided below the feed roller 39 is opened. Then, in this state, the feed conveyor 3 is rotated forward (= in the same direction as the crushing operation) to convey the stagnant relatively stagnant portion of the hopper 2 on the side of the crushing device 16 to open and close the first opening and closing. By dropping through the opening of the door 47 and reversing the feed conveyor (= in the direction opposite to the direction of the crushing operation), a portion of the hopper 2 relatively opposite to the crushing device 16 (including the space P, for example). Is transported and dropped from the opening of the second opening / closing door 48. Thereby, the dropped wood is moved by the self-propelled wood crusher of the unloading conveyor 7 via the chute 52 (see FIG. 11) provided in the main body frame crusher mounting portion 10A so as to be located below the second opening / closing door 48. It can be introduced into the front side portion and can be carried out by the carry-out conveyor 7 to the rear side outside of the self-propelled wood crusher. Therefore, it is possible to receive the unloaded piece of wood by a bucket of a separately provided self-propelled transport machine (for example, a wheel loader) and transport the piece to a predetermined position. In addition, after the crushed wood is first loaded at a predetermined position on the unloading conveyor 7 during the crushing operation, the traveling device 11 is allowed to self-propelled (or may be slightly turned) to the front side, so that the self-propelled wood crushing is performed. The position of the machine is shifted, and in that state, the pieces of wood are unloaded by the unloading conveyor 7 and loaded at a position different from the loading position of the crushed wood, so that the pieces can be stacked in a sorted and sorted form. .
[0114]
Further, in the present embodiment, the second opening / closing door 48 is also provided on the driven roller 40 side, so that, for example, a piece of wood staying in a portion of the hopper 2 relatively opposite to the crushing device 16. With regard to the above, the feed conveyor 3 can be transported in the reverse direction while opening the second opening / closing door 48, and can be dropped from the opening. In this case, for example, the dropped wood may be directly received and accumulated in predetermined receiving means such as a bucket of a self-propelled transport machine (for example, a wheel loader). In this case, as the receiving means, in addition to the above, for example, a removable receiving device is provided on the self-propelled wood crusher side, and when a predetermined amount is accumulated, the receiving device is removed and transported together with the receiving device to another place. You may. FIG. 27A is a view showing a case in which a receiving tool 53 is provided in the main body frame crusher mounting portion 10A as such an example. FIG. 27B is an arrow view as viewed from the XXVII direction in FIG.
[0115]
27 (a) and 27 (b), the receiving tool 53 is provided below the second opening / closing door 48, and includes a bottom plate 53a, left and right plates 53b, 53b, and an end plate 53c. In the space formed in each of these plate portions 53a, 53b, 53b, 53c, a piece of wood dropped from the second opening / closing portion 48 can be received and stored.
[0116]
Further, the receiving tool 53 is provided with flanges 53d, 53d at the upper ends of the side plates 53b, 53b, respectively, inward in the left and right directions. On the other hand, corresponding to these, flanges 54, 54 are provided at the lower end of the main body frame crusher attachment portion 10A outward in the left and right directions. The flanges 53d of the receiving tool 53 are inserted into gaps between the flanges 54, 54 and the main frame crusher mounting part 10A, so that the receiving tool 53 is engaged with the main frame crusher mounting part 10A. It has been stopped.
[0117]
When removing the receiving tool 53 from the self-propelled wood crusher, the receiving tool 53 is moved to the rear of the self-propelled wood crushing machine, for example, by gripping a handle 53e provided on the side plate 53b with an appropriate gripping tool or hanging it with a hanging tool. By sliding to the side (the right side in FIG. 27 (a)), the flanges 53d are separated from the gaps between the flanges 54, 54 and the main frame crusher mounting portion 10A, and the receiving tool 53 is moved to the main body. It is released from the frame crusher mounting portion 10A.
[0118]
As described above by taking some of the techniques as examples, in the present embodiment, after the crushing operation is completed, the remaining wood pieces are collected and concentrated from the open / close doors 47 and 48 using the transport function of the feed conveyor 3. As a result, the cleaning work can be easily performed, and the labor burden of the wood piece cleaning work can be reduced as compared with the conventional manual work.
[0119]
As described above, the wood pieces stored in the space P between the driven roller 40 and the front wall 2a are re-conveyed to the crushing device 16 side by the feed conveyor 3 when a certain amount is accumulated, In order for this re-transport function to function effectively, the height of the front wall 2a must be somewhat higher than the transport surface of the feed conveyor 3 as shown in FIGS. Before that, it overflows from the lower front wall 2a and spills out of the hopper 2). As a result, when a relatively long piece of wood to be crushed (for example, one that is longer than the longitudinal dimension of the hopper 2) is to be thrown into the hopper 2 during the crushing operation, the front wall 2a having one end of the wood is high as it is. And may be caught by friction and hinder smooth conveyance by the feed conveyor 3.
[0120]
Therefore, in the present embodiment, the rotating roller device 51 is provided above the front wall 2a. Thereby, it is possible to eliminate the snagging due to the above-mentioned interference and to smoothly convey the sheet by the feed conveyor 3.
[0121]
In the above, the case where the pressing conveyor device 5 including the pressing roller 54, the introducing roller 55, and the endless track member 56 is provided as the pressing and introducing means has been described as an example, but the present invention is not limited to this. That is, for example, as described in the above-mentioned JP-A-2002-1159, a pressing roller provided above the feed conveyor 3 (conveying means) and in the vicinity of the crushing device 16 as a press-introducing means is provided. Alternatively, a structure in which the wood to be crushed is pressed and introduced into the crushing device 16 in cooperation with the transporting means may be used. In this case, a similar effect is obtained.
[0122]
In the above description, a wood crusher provided with a so-called impact crusher in which a cutting tool (crushing bit 18) is attached to the outer peripheral portion of the crushing rotor 20 has been described as an example of a crushing device. However, the present invention is not limited to this. For example, a cutter is provided on a shaft arranged in parallel, and a crushing device (a so-called two-axis shearing machine including a shredder) that shears a crushed object by rotating in opposite directions, or a roll-shaped rotating body (rotor). A rotary type crusher (a six-axis crusher including a so-called roll crusher) that crushes a crushed object by sandwiching the crushed object between the rotating bodies by rotating the pair in opposite directions with a pair of crushing blades attached. And the like, and a wood crusher provided with a so-called wood chipper that converts the crushed material into chips. In these cases, the same effects as above can be obtained.
[0123]
Furthermore, in the above, the case where the present invention is applied to a self-propelled self-propelled timber crusher that has been described as an example is described. Needless to say, the present invention may be applied to a portable wood crusher that can be lifted and transported by a crane or the like, or a stationary wood crusher that is arranged as a fixed machine in a plant or the like. Get.
