And are fixed by screws 304.

Further, a biting flange 313 is formed on the outer peripheral portion of the roller main body 312 of the auxiliary rollers 31 and 31a on the entire circumference in the direction of rotating around the rotation shaft 311. The leading edge of the biting flange 313 is sharply formed and easily bites into the surface of the workpiece. Note that the leading edge of the biting flange 313 may be slightly rounded to make it difficult to cut into the bamboo.
In the attached state, the auxiliary rollers 31 and 31a are configured such that each rotary shaft 311 has the same height as the upper surface of the feed table 30, and the upper half of the auxiliary rollers 31 and 31a protrude from the upper surface of the feed table 30. (See FIG. 4 (c)). Furthermore, the axial direction of each rotating shaft 311 is set with a slight inclination angle almost parallel to the feed direction of the workpiece (see FIG. 4A).

  The driving roller 32 positioned above the auxiliary rollers 31 and 31a is attached to a rotating shaft 320 and a plurality (8 in this embodiment) of the rotating shaft 320 in the longitudinal direction of the rotating shaft 320 at a required interval.

  A hydraulic motor 33 is attached to a wide portion in the middle of the arms 322 and 323 so as to pass between the arms 322 and 323. The hydraulic motor 33 is driven by a hydraulic system (not shown) having a hydraulic pump driven by the power of the engine, and the rotation speed can be adjusted.

  A sprocket 331 is attached to the tip of the rotating shaft 330 of the hydraulic motor 33. A chain 332 is hung on the sprocket 331 and the sprocket 324, and the driving roller 32 rotates counterclockwise as indicated by an arrow a1 in the view of arrow B in FIG. The drive roller 32 can be moved up and down about the shaft 307 as the center of rotation.

  A fitting shaft 325 is fixed to the distal end of the arm 322 on the rear side, and a pipe-like handle 326 (see FIG. 4C) for manual operation is detachably attached to the fitting shaft 325. is there. A support rod 327 is attached in the vicinity of the end of the handle 326 on the insertion side with the base portion pivotally attached thereto. The support rod 327 is used like a support rod with its lower end applied to the upper surface of the edge of the front feed table 301 in order to maintain a constant height when the drive roller 32 is raised by operating the handle 326. To do.

  Note that the axial direction of the rotation shaft 320 of the drive roller 32 is a slight inclination angle that is horizontal and substantially parallel to the feed direction a0 (see FIG. 4A) of the workpiece as shown in FIG. Is set. This inclination direction is opposite to the inclination direction of each rotation shaft 311 of the auxiliary rollers 31 and 31a. As a result, when a workpiece such as bamboo is sandwiched between the driving roller 32 and the auxiliary rollers 31 and 31a from above and below and sent in cooperation, the following acts.

  That is, when each tooth plate 321 of the drive roller 32 rotates in the direction of the arrow a1, the lower feed dog of each tooth plate 321 bites into the surface of the object 4 to be processed, and the object 4 is moved in the direction of the arrow a2. Rotate. As a result, the auxiliary rollers 31 and 31a that are in contact with the surface of the workpiece 4 are rotated in the direction of the arrow a3 (see FIG. 4C).

  The lower rotation of each tooth plate 321 by the rotation in the direction of the arrow a1 includes a force vector in the same direction as the feed direction a0 of the workpiece 4, and the upper rotation of the auxiliary rollers 31 and 31a by the rotation in the direction of the arrow a3. Also includes a force vector in the same direction as the feed direction a0 of the workpiece 4. As a result, the driving roller 32 and the auxiliary rollers 31 and 31a cooperate to send the workpiece 4 in the direction of arrow a0, which is the feeding direction, while spirally rotating the workpiece 4.

  That is, the rotation shaft 311 of each auxiliary roller 31, 31 a is configured so that the rotation direction of the outer peripheral portion of each auxiliary roller 31, 31 a is forward with respect to the helical rotation of the workpiece 4 provided by the drive roller 32. Are arranged so as to intersect with the rotation axis 320 of the other.

  As described above, the rear guide 35 for guiding the workpiece is attached to the upper surface of the guide member 309a of the rear feed table 302 behind the auxiliary rollers 31, 31a and the drive roller 32.

The front guide 36 is attached so as to be movable and adjustable in the width direction, and can guide the rod (not shown) extending through the upper lid 308 and extending downward to the side surface of the workpiece.

Please refer to FIG.
Since the pulverizer C1 pulverizes, for example, a long bamboo or the like of about 4 m as an object to be processed, it is combined with a receiving stand 5 for supporting the object to be processed in a substantially horizontal state in cooperation with the feed table 30. Can be used.
The receiving stand 5 includes inverted V-shaped legs 50 and 51, and height adjusters 52 and 53 are attached to the upper portions of the legs 50 and 51 so that the height adjusters 52 and 53 can be slid in the vertical direction. Further, the legs 50 and 51 are connected by crossed reinforcing members 54. Between the upper ends of the height adjusting bodies 52 and 53, a receiving wire 55 provided with a tension spring (not shown) on one end side is bridged and attached.

  When the receiving stand 5 is used, it is installed at a required distance behind the pulverizer C1 so as to support the rear end side of the long workpiece 4 (bamboo in FIG. 6). Thus, the force required when pressing the front portion of the workpiece 4 with the pressing roller 24 can be reduced so that the front portion of the workpiece 4 does not rise upward due to the weight of the rear portion. In addition, since bamboo is generally not linear, the whole can be shaken by rotating in the circumferential direction, but by receiving the back side of the bamboo with the receiving wire 55 having the above structure, the bamboo can be rotated without difficulty while offsetting the movement of the bamboo. be able to.

(Function)
With reference to FIG. 1 thru | or FIG. 6, the effect | action of the grinder C1 which has the feeder 3 is demonstrated.
Hereinafter, an example in which a bamboo having a relatively large diameter (Moso bamboo) is pulverized as the workpiece 4 will be described.

  First, the operator operates the handle 326 to raise the drive roller 32 against the pulling force of the tension spring 328, the lower end of the support rod 327 of the handle 326 is brought into contact with the upper surface of the edge of the front feed table 301, and the drive roller 32 is supported at a certain height. Then, the workpiece 4 cut to a required length (for example, about 4 m) is placed on the feed table 30. The rear end side of the workpiece 4 is placed on and supported by the receiving wire 55 of the receiving stand 5.

  The front end side of the workpiece 4 is passed between the driving roller 32 and the auxiliary rollers 31 and 31 a of the feeding device 3, and the front end is positioned behind the pressing roller 24. The support by the support rod 327 is removed, and the tooth plate 321 of the drive roller 32 and the auxiliary rollers 31 and 31a are sandwiched from above and below by using the tensile force of the tension spring 328 (FIGS. 4A and 4C). )reference). Thereafter, the handle 326 is removed.

Further, the position of the pressing roller 24 in the axial direction of the rotating shaft is adjusted, and the workpiece 4 is regulated from both sides by the rear guide 35 and the front guide 36, and as shown in FIG. In view, it should be parallel or slightly inclined in the front-rear direction. In this way, it is possible to adjust the angle of the approach direction with respect to the crushing portion of the workpiece to be sandwiched between the driving roller 32 and the auxiliary rollers 31 and 31a and pressed by the pressing roller 24.
When the workpiece 4 is sent with an inclination, the area of the pulverized surface that is hit when pulverized by the blades 224 of the pulverizing rotor 22 is wider than when the crushed rotor 22 is sent in parallel. can do.

  In addition, since the area of the pulverized surface (the end surface) of the workpiece 4 is increased, the number of the blades 224 that are in contact with the pulverized surface of the workpiece 4 at the time of pulverization increases in the number of arrangement directions (axial direction of the rotary shaft 320). Each blade body 224 can be used without waste. Further, when the workpiece 4 rotates in the circumferential direction, the newly pulverized portion faces the blade body 224 that rotates from the top to the bottom of the grinding rotor 22 from the bottom to the top. Since it rotates, the pulverization efficiency is improved from this point.

  Next, the crushing rotor 22 of the crushing unit 2 of the crusher C1 is driven, and the hydraulic motor 33 is operated to drive the drive roller 32 of the feeding device 3. Since the rotation shaft 320 of the driving roller 32 is arranged so as to intersect the direction of the arrow a0 sent to the crushing unit 2 so as to give the workpiece 4 a helical rotation in the traveling direction, as described above, the driving roller 32. When each tooth plate 321 rotates in the direction of arrow a1, the lower feed dog of each tooth plate 321 bites into the surface of the object to be processed 4 and rotates the object to be processed 4 in the direction of arrow a2. As a result, the auxiliary rollers 31 and 31a that are in contact with the four surfaces are driven to rotate in the direction of the arrow a3.

The lower rotation of each tooth plate 321 by the rotation in the direction of the arrow a1 includes a force vector in the same direction as the feed direction a0 of the workpiece 4, and the upper rotation of the auxiliary rollers 31 and 31a by the rotation in the direction of the arrow a3. Also includes a force vector in the same direction as the feed direction a0 of the workpiece 4.
As a result, the driving roller 32 and the auxiliary rollers 31 and 31a cooperate to feed the workpiece 4 in the direction of the grinding rotor 22 while spirally rotating the workpiece 4.

  When the workpiece 4 is sent to the pressing roller 24, the pressing roller 24 is raised as described above, and after passing the workpiece 4, the pressing roller 24 is lowered and the pressing roller 24 is biased by the urging force of the tension spring 244. The workpiece 4 is sandwiched between the front feed table 301 and stabilized so that the workpiece 4 does not get out of order. In this state, the workpiece 4 can be further crushed by the crushing rotor 22 as described above by further feeding in the arrow a0 direction which is the feeding direction.

  Note that there is a slight distance between the driving roller 32 and the auxiliary rollers 31 and 31a and the crushing rotor 22, and in the crushing process, the workpiece 4 remains at the end of this distance, so the next workpiece 4 is set. It is necessary to take out before doing. At this time, the rotation of the driving roller 32 is stopped in a state where the rear end side of the workpiece 4 is partially engaged with the driving roller 32 and the auxiliary rollers 31 and 31a, and the driving roller 32 is rotated in the reverse direction, so that the workpiece is processed. 4 is sent backward to be taken out.

  As described above, the feeding device 3 according to the present invention has a relatively simple structure of the feeding device 3 as compared with the conventional bamboo powder manufacturing machine using the chuck mechanism, and the pulverizer C1 including the feeding device 3 is used. The whole is compact. Further, the setting work of the object to be processed 4 is simple by simply sandwiching the front end side of the object to be processed 4 between the driving roller 32 and the auxiliary rollers 31 and 31a of the feeding device 3, and the remaining part can be easily removed. So it has excellent workability.

Please refer to FIG.
The pulverizer C2 has substantially the same structure as the pulverizer C1, but the structure of the feeding device 3a is partially different from the feeding device 3 of the pulverizer C1. In FIG. 7, the same or equivalent parts as those of the pulverizer C <b> 1 are denoted by the same reference numerals, and description of the structure overlapping with the pulverizer C <b> 1 is omitted.

  The feed table 30a of the feed device 3a has a rear feed table 302a. The rear feed table 302a is formed such that both sides (both sides in the vertical direction in FIG. 7) are rearward and wide at the same angle. Guide members 309b and 309c for guiding an object to be processed such as bamboo are formed on both side edges of the rear feed table 302a so as to rise up to the upper surface side over the entire length of the edge.

  Rear guides can be attached to the upper surfaces of the front portions of the guide members 309b and 309c, respectively. As in the case of the pulverizer C1, when the workpiece is moved toward one side in the width direction of the rear feed table 302a (upper side in FIG. 7) and fed, the rear guide 35 (illustrated by imaginary lines) is guided to the opposite guide member 309c. Install. Further, when the work piece is sent to the other side (lower side in FIG. 7) in the width direction of the rear feed table 302a, the rear guide 35a is attached to the guide member 309b.

  The rear guide 35a attached to the guide member 309b is not the same shape as the rear guide 35, but has a plane symmetrical shape. In addition, the rear guides 35 and 35a may be selectively attached to the guide members 309b and 309c each time as necessary, or are always attached to the guide members 309b and 309c to guide the object 4 to be processed. The rear guide on the non-use side may be rotated outward so as not to get in the way.

  According to the pulverizer C2, similarly to the pulverizer C1, the workpiece 4 such as bamboo can be sent to the guide member 309b of the rear feed table 302a, and in addition, the feed direction of the workpiece 4 is driven. It is also possible to send the workpiece 4 to the guide member 309c so as to be in a direction substantially parallel to the axial direction of the rotation shaft 320 of the roller 32.

  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. Further, it goes without saying that various modifications are possible within the scope of the technical idea of the present invention.
