More specifically, functions that take into account the characteristics of bamboo materials, such as being able to crush long materials to be crushed, such as bamboo materials and wood, and in particular, can send bamboo materials with branches and leaves as they are to the crushing section without fail. The present invention relates to a crusher suitable for crushing bamboo.

  Bamboo has been loved and enjoyed since ancient times for its unique scenery as a form of bamboo, along with its practicality as a material for making various accessories and crafts. In addition, well-managed bamboo groves have produced excellent disaster prevention effects in terms of wind and earthquake resistance. However, in recent years, with the import of cheap foreign firewood and bamboo materials, Due to the declining nature and the aging of landowners, more bamboo forests are being left.

  Bamboo has a thriving fertility, so in bamboo forests, if it is not adequately managed, such as thinning out, it will grow out of reach in a very short period of time. It is necessary to efficiently dispose of the thinned bamboo. For the disposal of such bamboo, a crusher for crushing bamboo into chips is used. An example of a crusher that can crush bamboo is shown below.

However, the conventional crushing device has the following problems.
The crushing device has a structure in which bamboo is fed to the work presser by a belt conveyor (carrying conveyor), but the bamboo stems (竿) are overhanged with highly flexible branches and leaves. Since the repulsive force is in the way, it is practically difficult to efficiently send bamboo with a belt conveyor.
Further, the crushing device is a dedicated machine for crushing bamboo, and it is difficult to crush timber such as thinned wood and pruned wood of roadside trees due to the structure of the work presser and work cutting machine.
Furthermore, in the crushing device, a small and low-speed rotation type single-shaft crusher is employed in order to suppress noise. For this reason, even if noise is suppressed to some extent, it cannot be said that the crushing capacity is sufficient and efficient crushing treatment cannot be performed.

Similarly, it is only for the purpose of facilitating understanding of the contents, and the meaning of each component is not limited to the above-described parts.

When crushing bamboo with a crusher, the bamboo is carried into the crushing section (3) by the carry-in conveyor (20) of the material carrying-in section (2).
Bamboo main shaft (bamboo) has branches and leaves that are highly flexible, and it is not easy to carry with just the carry-in conveyor (20) because the poor adhesion and repulsive force of the branches and leaves will interfere. Although the transfer rotor (21) cannot be efficiently transported, the upper end of the rotation locus of the feed rotor (21) is higher than the feed surface of the carry-in conveyor (20), so it is easy to hang on each part of bamboo, and the carry-in conveyor (20) and the feed rotor ( By the synergistic action of 21), bamboo can be efficiently sent to the crushing part (3).

  The crusher provided with an adjusting means for adjusting the strength of biting the bamboo or wood of the feeding device (34) into two stages, when crushing the bamboo, set the adjusting means for bamboo material, ) Can be crushed and sent to the crushing rotor (35).

  Thus, chipping can be performed efficiently by being crushed by the feeding device (34) before being crushed by the crushing rotor (35). Bamboo has a strong bending force, and if it is pinched while maintaining strong flexibility or elasticity without being crushed, if a strong force is applied to the tip by the crushing rotor (3), There is a risk that the bamboo will be exposed to danger due to violence. However, the above danger can be avoided by weakening the flexibility of the portion where the bamboo material is crushed and bitten.

In addition, when crushing wood, by setting the adjusting means for wood, the wood that has been carried in by the carry-in conveyor (20) can be maintained within a range that does not interfere with the feeding of the wood, for example. The pressing portion of the feeding device (34) can be fed to the crushing rotor (35) without being bitten while moving along the shape of the wood.
Thus, the crusher can suitably perform any crushing work of bamboo or wood depending on the setting of the adjusting means.

The crushing rotor (35) includes a blade base member (355) provided on the outer peripheral portion thereof, and a tightening member (357) provided on the rear side in the rotation direction from the blade base member (355). ) Is fastened between the blade base member (355) and the clamping member (357), the blade member (359) is fixed to the blade base member (355), so the crushing rotor rotates at high speed. A sufficient crushing capacity can be secured as a mold.
That is, even if the crushing rotor is rotated at a high speed and the bamboo material and the like are crushed, the portion holding the blade member (359) does not turn and the deformation does not occur. Crushing is possible.

  The engine room (11) has an engine room (11) with an engine (110), and the air intake (113) is separated from the material carrying part (2) and the crushing part (3) where dust is generated. The crusher provided in the upper part can reduce the amount of dust sucked in, thereby making it difficult for the radiator (111) to be clogged.

The present invention has the following effects.
(A) According to the present invention, the bamboo material with branches and leaves can be reliably fed into the crushing part as it is by the synergistic action of the feed rotor and the conveyor, and a crusher particularly suitable for crushing bamboo material can be provided.

(B) This invention can provide the crusher which can crush timbers, such as a thinning material and the pruning material of a roadside tree, besides a bamboo material by the setting of an adjustment means.

(C) In the present invention, even if the crushing rotor is rotated at high speed and the bamboo material is crushed, the portion holding the blade member is not turned and the deformation is excellent and the durability is high. Crushing by rotation is possible. Thereby, sufficient crushing capability can be secured.

(D) The present invention has an engine room with a built-in engine, and reduces the amount of dust sucked by providing an air intake at the upper part of the engine room away from the material carrying part and the crushing part where dust is generated. This can prevent the radiator from being clogged.

(Crushing part 3)
Reference is mainly made to FIG.
The crushing unit 3 has a case 30 provided following the front end of the material carrying-in conveyor 20. The inside of the case 30 is partitioned into a rear-side pretreatment chamber 31 and a front-side crushing chamber 32 via a partition wall 302 provided with an introduction port 301 in the lower portion. A feeding device 34 is provided in the pretreatment chamber 31, and a crushing rotor 35 is provided in the crushing chamber 32.
The feeding device 34 and the crushing rotor 35 are both driven by a hydraulic motor, but a known drive system including the hydraulic motor is employed, and illustration and description thereof are omitted.

  An upper maintenance cover 33 is provided at the upper part of the case 30. The lid 33 has two lid plates 331 and 332, and the lid plates 331 and 332 are connected to each other via a shaft 333 so as to be able to rotate up and down. The rear cover plate 331 corresponds to the pretreatment chamber 31, and the front cover plate 332 corresponds to the crushing chamber 32.

  Brackets 334 and 335 are provided at the front ends of the cover plates 331 and 332, respectively. A cylinder base of a hydraulic cylinder 336 is pivotally attached to the bracket 334 of the lid plate 331, and a rod head of the hydraulic cylinder 336 is pivotally attached to a bracket 335 of the other lid plate 332. Yes. The hydraulic cylinder 336 is attached so that the cover plates 331 and 332 close the inside of the case 30 when the rod is extended.

  With this structure, for example, if only the cover plate 331 is closed and fixed by the fixing means, the other cover plate 332 can be opened upward and tilted by contracting the rod of the hydraulic cylinder 336. On the other hand, if only the cover plate 332 is fixed, the other cover plate 331 can be lifted and inclined to open by contracting the rod of the hydraulic cylinder 336.

  The feeding device 34 provided in the pretreatment chamber 31 includes a movable frame 341. Gears 342 and 343 are provided on the front and rear of the movable frame 341, and an endless belt 344 is wound around the gears 342 and 343. The endless belt 344 is configured by joining a plurality of metal plates, and rotates in the feed direction (clockwise in FIGS. 1 and 5) as the gears 342 and 343 rotate.

  The upper part of the movable frame 341 is pivotally supported on both side plates (reference numerals omitted) of the case 30 so as to be rotatable. The rotation center of the movable frame 341 is the shaft 345 of the gear 343 on the rear side.

Further, brackets 304 are provided on both side plates of the case 30 so as to protrude upward. A hydraulic cylinder 347 is attached to each bracket 304 with a cylinder base pivotally supported. The rod head of the hydraulic cylinder 347 is pivotally attached to both lower ends 346 of the movable frame 341 so as to be pivotable.

  With this structure, the front side of the feeder 34 can be rotated in the vertical direction by each hydraulic cylinder 347. The pressing force by the rod of the hydraulic cylinder 347 can be adjusted in two steps by a changeover switch (not shown). One of the adjustment stages is such that the pressing force is set to be relatively weak, and the hydraulic cylinder 347 acts like a spring and is suitable for feeding wood that is hard and not easily crushed.

  Further, the other of the adjustment stages is set to have a relatively strong pressing force, and is suitable for feeding bamboo material that can be crushed. The bamboo material is easily chipped in the crushing rotor 35 by being crushed on the front side of the feeding device 34. In addition, the bamboo material can be held between the feeding device 34 and the material carry-in conveyor 20 so that the bamboo material is broken, so that the bamboo material can be prevented from being violated so that the worker can work safely.

The crushing rotor 35 provided in the crushing chamber 32 has a rotating shaft 351. The rotation shaft 351 is a high-speed rotation type in which power is transmitted by a drive system.
Seven rotating discs 352 are fixed to the rotating shaft 351 at equal intervals in the axial direction. The rotating shaft 351 passes through the center of each rotating disk 352. Each rotary disk 352 is not a disk, but has an irregular shape having portions 353 that gently swell at three locations in the circumferential direction of the outer periphery.

  A blade base member 355 having a rectangular cross section is passed between the turntables 352 so as to pass through each turntable 352 so as to pass through a substantially rectangular cutout 354 provided in each of the swollen portions 353. It is fixed. The blade base member 355 is fixed so that both end surfaces in the length direction are flush with the outer surface of the rotating disk 352 located at both ends.

  Note that a part of the notch portion 354 of each rotary plate 352 is open, and the receiving surface 355a of the blade base member 355 is fixed so as not to block the open portion 354a. The receiving surface 355a of the blade member 355 is inclined by about 35 ° with respect to a line in the diameter line direction of the rotating shaft 351 (a line connecting the center of the rotating shaft 351 and the outer end (corner portion) of the receiving surface 355a). . In the blade member 355, bolt through holes 356 are formed at six positions between the respective rotary disks 352 so as to penetrate from the receiving surface 355 a to the opposite surface.

  A clamping plate 357, which is a clamping member, is fixed to the opposite side of the notch portion 354 of each rotary disk 352 by welding so as to pass between the rotary disks 352. The fastening plate 357 is fixed so that both end surfaces in the length direction are flush with the outer surface of the rotating disk 352 located at both ends. A pressing surface 357a on the inner side of the clamping plate 357 is configured to be parallel to the receiving surface 355a of the blade base member 355. In the tightening plate 357, bolt through holes 358 are formed at six positions between the respective rotary plates 352 so as to penetrate from the pressing surface 357a to the opposite surface.

  Two blade plates 359 that are blade members are inserted side by side in the length direction into a gap formed between the pressing surface 357a of the clamping plate 357 and the receiving surface 355a of the blade base member 355 ( (See FIG. 3). Each blade plate 359 is formed to have a length that is ½ of the length of the fastening plate 357. The blade portion 359a of each blade plate 359 has a single blade shape with a blade angle of about 45 °, and is provided on both sides of the blade plate 359 in the width direction. Further, the blade plate 359 is provided with bolt through holes 359b penetrating the front and back surfaces at positions corresponding to the respective bolt through holes 356 and the respective bolt through holes 358.

  The thickness of the blade plate 359 is slightly narrower than the width of the gap, and is somewhat resistant when inserted. Thus, the blade plate 359 is sandwiched between the clamping plate 357 and the blade base member 355 by tightening the bolts and nuts 350 passed through the respective bolt through holes 356, the respective bolt through holes 359b, and the respective bolt through holes 358. Is fixed. The blade plate 359 has a blade portion 359a slightly protruding from the outer peripheral surface of each rotating disk 352, and is attached with a rake angle of about 55 °.

Each blade plate 359 is used in two pieces at three locations in the circumferential direction of the crushing rotor 35, but can be made larger. However, since the blade plate is heavy, it is more preferable to divide the blade plate into a plurality of parts in terms of improving workability such as replacement of the blade plate.
Further, the blade mounting structure portion including the blade base member 355, the clamping plate 357, each blade plate 359, and the bolt / nut 350 has an action of increasing the inertial force in the rotational direction of the crushing rotor 35 by its weight. .

The crushing rotor 35 having the above-described structure is pivotally supported in front of the introduction port 301 such that the direction of the rotation shaft 351 is horizontal and perpendicular to the feeding direction of the material to be crushed by the material carrying-in conveyor 20.
A filter plate 36 is provided below the crushing rotor 35. The filter plate 36 constitutes the lower side of the crushing chamber 32. The filter plate 36 is formed with a number of through holes (reference numerals omitted) through which a chip of a required size can pass. The chips crushed by the crushing rotor 35 remain in the crushing chamber 32 until they are large enough to pass through the through holes, and are repeatedly crushed.

(Discharge unit 4)
A discharge conveyor 40 is provided below the base frame 10 of the chassis 1 from the front and rear intermediate portions of the base frame 10 to the front end. The discharge conveyor 40 is a belt conveyor. The discharge conveyor 40 includes a fixed conveyor 40a provided horizontally on the rear side, and a movable conveyor 40b provided on the front side so as to be able to rotate in the vertical direction. The belt 41 of the discharge conveyor 40 moves around from the fixed conveyor 40a to the movable conveyor 40b. In the base frame 10, a through hole (reference numeral omitted) is provided below the filter plate 36 corresponding to the rear portion of the fixed conveyor 40 a.

  The base end portion of the movable conveyor 40b is pivotally supported by a bracket 42 provided at the front end portion of the fixed conveyor 40a so that the movable conveyor 40b can rotate in an angle range from a position inclined upward at a required angle to a vertical position. The movable conveyor 40b can be rotated in the vertical direction by a hydraulic cylinder 43 whose cylinder base is rotatably attached to the upper end of the bracket. The movable conveyor 40b is maintained in an inclined state during the crushing operation, and is maintained in a vertical state for safety when the crusher A is run.

(Function)
With reference to FIG. 1 thru | or FIG. 5, the effect | action of the crusher A which concerns on this Embodiment is demonstrated.
First, the case where the bamboo material 5 is crushed by the crusher A will be described.
Refer mainly to FIG. 1 and FIG.

(1) First, the movable conveyor 40b of the front discharge conveyor 40 is tilted and stopped so that the tip is raised. Further, the rear auxiliary conveyor 26 is leveled, and the stopper 262 at the tip of each hanging rod 261 is stopped on the wheel 263 of the auxiliary conveyor 26.
(2) The engine 110 in the engine room 11 is started and a drive system such as a hydraulic motor is operated. Thereby, the material carrying-in conveyor 20, the feeder 34, the crushing rotor 35, and the discharge conveyor 40 operate | move. Further, the pressing force by the rod of each hydraulic cylinder 347 is set to the strong side for bamboo by the changeover switch. The lower surface of the front side of the feeding device 34 is lowered to the vicinity of the belt of the material carry-in conveyor 20.

(3) The bamboo material 5 with the leaves and leaves attached is sequentially placed on the material carry-in conveyor 20 with the root side forward. Even if the total length is long, it can be sent without trouble by being placed on the auxiliary conveyor 26 without being inclined. Since the feed rotor 21 is set higher than the material carry-in conveyor 20 and the auxiliary conveyor 26, each claw wheel 212 of the feed rotor 21 is easily hooked on each part (especially a branch leaf part) of the bamboo material 5, and each bamboo material 5 is attached. It can be hooked and sent reliably. Further, even if the branches and leaves of the bamboo material 5 are greatly expanded, the bamboo material 5 is accommodated on the material carry-in conveyor 20 by the slanted hanging rods 261 and the both side plates 25.

(4) Each carried bamboo material 5 is pinched between the front side of the endless belt 344 of the feeding device 34 and the upper surface of the material carrying conveyor 20 and is bitten. As described above, since the pressing force by the rod of each hydraulic cylinder 347 is set on the strong side for bamboo material, the bamboo material 5 is broken by the pressing force. The bamboo material 5 has a strong bending force. If the strong force of the crushing rotor 3 acts on the tip of the bamboo material 5 while it is sandwiched while maintaining strong flexibility or elasticity without being crushed, the bamboo material 5 on the material carry-in conveyor 20 will run wild. There is a risk of danger to workers. However, the above-mentioned danger can be avoided by weakening the flexibility of the portion where the bamboo material 5 is crushed and bitten as described above.

(5) The broken bamboo material 5 passes through the inlet 301 and is finely crushed by the crushing rotor 3 rotating at high speed. When the bamboo material 5 is being crushed by the crushing rotor 3, an extremely strong force acts on each blade plate 359, but the blade base member 355 and the fastening plate 357 in which each blade plate 359 is firmly fixed to each rotary plate 352. Since it is sandwiched between and fixed, it has excellent strength and durability, so that the angle of each blade plate 359 changes, or the rear side of each blade plate 359 turns over in the rotation direction of each rotary plate 352. Deformation can be prevented.

(6) The bamboo chip crushed by the crushing rotor 35 in the crushing chamber 32 passes through the filter plate 36, passes through the through-hole of the base frame 10, and is placed on the rear part of the discharge conveyor 40. The chips are fed forward through the movable conveyor 40b inclined from the fixed conveyor 40a, and are put into and accommodated in a storage bag (not shown) placed downward from the tip of the movable conveyor 40b.

Next, the case where the timber 6 such as thinned wood is crushed by the crusher A will be described.
Reference is mainly made to FIG.

When the wood 6 is crushed, the pressing force by the rod of each hydraulic cylinder 347 is set to the weak side for wood by a changeover switch.
As in the case of the bamboo material 5, when the wood 6 sent by the material carry-in conveyor 20 is sent to the feeding device 34, the front side of the endless belt 344 of the feeding device 34 applies a pressing force to the wood 6. It maintains in the range which does not have trouble in sending, and feeds to the crushing rotor 3 side, moving up and down along the shape of the timber 6. Since the following crushing and chip discharge are the same as in the case of the bamboo material 5, description thereof will be omitted.

  Note that the terms and expressions used in this specification are merely explanatory and are not limiting at all, and terms and expressions equivalent to the features described in this specification and parts thereof. There is no intention to exclude. It goes without saying that various modifications are possible within the scope of the technical idea of the present invention.
