Description

  The present invention relates to a cutting device that draws a processing object such as a fruit tree, a pruned branch of a tree, a leaf tobacco, or a remaining stem of tea from its one side end, conveys it so that the end precedes, and chops and transfers it And a remaining trunk processing machine.

  The cutting device for shredding such a processing object and the cutting part of the remaining trunk processing machine are classified into a cylinder type and a flywheel type depending on the structure (see Non-Patent Document 1). The cylinder-type and flywheel-type cutting devices are common in that both have a rotary blade and a fixed blade, but differ in that the structure of the rotary blade is different. That is, one or two cylinder-shaped rotary blades are provided on the rotary drive shaft, are arranged at a predetermined interval from the rotary drive shaft, and extend along the rotary drive shaft. When there are two rotary blades, these rotary blades are arranged opposite to each other with the rotary drive shaft as the center. The fixed blade is disposed along the rotational drive shaft at a position near the outside of the rotating rotary blade. The object to be processed is transferred to a position above the blade surface of the fixed blade, and is cut while being sandwiched between the rotating blade and the fixed blade.

  On the other hand, the flywheel-shaped rotary blade is plate-shaped, and is attached along the inner surface so that the blade surface faces the center side direction of the through hole formed on the inner surface of the disk-shaped flywheel. The flywheel-shaped fixed blade is attached to the base side and is arranged in the vicinity of the fixed blade that rotates. The object to be treated is inserted into the through-hole of the flywheel and cut while being sandwiched between the rotating rotary blade and the fixed blade.

  In each of the cutting portions of these conventional cylinder type and flywheel type cutting devices, the rotary blade is fixed to the rotary drive shaft and the flywheel. When trying to cut, there is a problem that a large impact force acts on the rotary blade and shortens the life of the rotary blade.

  In addition, the cylinder-type cutting device can easily adjust the gap between the fixed blade and the rotary blade by adjusting the mounting position of the fixed blade, while the rotary blade is a rod-like member that is spirally twisted. Therefore, even if this is rotated, the cut pieces of the processing object cannot be transferred in a predetermined direction. For this reason, there exists a possibility that a fragment may stay in a cutting part. On the other hand, the flywheel-type cutting device can transfer the fragments in a predetermined direction by a blowing action by a plurality of blades attached to the outer periphery of the flywheel. On the other hand, the clearance adjustment between the fixed blade and the rotary blade is performed by the flywheel. It is necessary to make adjustment so that the fixed blade does not contact the flywheel when the is rotating, and there is a problem that the adjustment work of the gap is troublesome.

  The present invention has been made in view of such problems, and a cutting apparatus and a residual stem processing machine that prevent a reduction in the life of a rotary blade and can perform a stable cutting operation without fragments remaining in the cutting apparatus. The purpose is to provide.

In order to achieve the above object, the cutting device of the present invention has a conveying roller that draws and conveys one end of the object to be processed (for example, the first rollers 21 , 22 , and the second rollers 23, 24 in the embodiment). And a processing object conveyed from the conveying roller by a cutting rotor in which a plurality of cutting blades are mounted radially on a rotation drive shaft that is rotatably supported downstream of the conveying roller in the conveying direction. A cutting blade disposed on the upstream side in the transfer direction of a processing object to be cut and transferred by a cutting rotor among a plurality of cutting blades. The distal end portion is bent toward the upstream side in the transfer direction, and the remaining cutting blades are bent toward the downstream side in the transfer direction .

According to the present invention, the shredding device is provided on the downstream side of the transporting direction of the transporting roller, and the base of the cutting blade of the cutting rotor provided in the shredding device is rotatably attached, so that the processing object is moved by the transporting roller. When conveyed to the shredding device, the object to be processed is cut by the rotating cutting blade. When the object to be processed is large or hard, the cutting blade rotates with its base as a rotation fulcrum. For this reason, a big impact force does not act on a cutting blade, and the lifetime reduction of a rotary blade can be prevented beforehand. Further, the tip of the cutting blade disposed on the upstream side in the transfer direction of the object to be processed is bent by the upstream side in the transfer direction, and the tip of the remaining cutting blade is bent downstream in the transfer direction. The processed object is cut by a cutting blade whose tip is bent downstream in the transfer direction, and a fragment of the processed object is conveyed downstream in the transfer direction by the action of the bent surface of the cutting blade. Further, the object to be processed that has been conveyed to the vicinity of the side plate on the upstream side in the transfer direction can be cut by a cutting blade that is bent toward the upstream side. For this reason, the conveyed processing target object can be shredded generally.

Moreover, this invention is provided with the blower which blows off the process target object shredded by the shredding apparatus .

According to the present invention, by providing a blower for blowing process object to shredding device, a fragment of the processing object that has been shredded by the shredding device is discharged by the blower. For this reason, it is possible to prevent the fragments from staying in the shredding device.

  Further, the present invention provides an opening adjusting means (for example, an opening adjusting portion in the embodiment) in which the shredding device and the blower communicate with each other via a partition plate having a communication hole, and the opening area of the communication hole can be adjusted to the partition plate. 80).

  According to this invention, the shredding device and the blower communicate with each other via the partition plate having the communication hole, and the opening adjustment means is provided in the partition plate, so that the opening area of the communication hole is easily adjusted by the opening adjustment means. can do. For this reason, it is possible to adjust the inflow amount of the shredded processing target piece flowing into the blower from the shredding device, restricting the inflow of the fragment into the blower exceeding the blower discharge capacity, It is possible to prevent clogging with fragments.

  Hereinafter, preferred embodiments of a cutting device and a remaining trunk processing machine according to the present invention will be described with reference to FIGS. In the present embodiment, a cutting apparatus and a residual stem processing machine that process objects to be processed such as leaf tobacco, sunflower, and corn among various cutting apparatuses and residual stem processing machines will be described as examples. For convenience of explanation, the directions of arrows shown in FIG. 1A will be described below as the front-rear direction and the left-right direction.

(First embodiment)
First, a cutting device according to a first embodiment of the present invention will be described. As shown in FIGS. 1 (a) and 1 (b) (side view), the cutting device 1 includes a pair of cutting device frames 10 that are opposed to each other with a predetermined interval in the left-right direction and extend in the front-rear direction. A pair of first rollers 21 and 22 and second rollers 23 and 24 that are opposed to each other with a predetermined gap in the vertical direction on the front side of the cutting device frame 10 and that draw and convey one end of the processing object S are provided. A plurality of cutting blades 33 are radiated and a base is rotated on a rotation drive shaft 32 that is rotatably supported by the conveyance device 20 and the conveyance device 20 on the downstream side (rear side) in the conveyance direction of the processing object S. A shredding device 30 that shreds the processing object S transported from the transporting device 20 by a freely attached cutting rotor 31 and transfers it in a predetermined direction. The shredding device 30 is attached with a shooter 70 that transports the shredded pieces of the processing object S to a predetermined position.

  The first rollers 21 and 22 of the conveying device 20 are arranged on the front side between the pair of cutting device frames 10, and the one end of the processing object S supplied from the front side of the cutting device 1 is used as a gap 25 between the rollers. Pull it in and transport it backwards. The pair of second rollers 23, 24 are disposed on the rear side of the pair of first rollers 21, 22, and pull back the one side end portion of the processing object S conveyed from the first rollers 21, 22. To the side. The pair of rollers are configured to rotate in a direction in which the opposite sides move to the rear side.

  Each surface portion of the first roller 21, 22 and the second roller 23, 24 is provided with a plurality of protrusions 26 that extend radially and have a predetermined interval in the circumferential direction and are linearly arranged in the longitudinal direction. Yes. The projecting portion 26 has a function of contacting the processing object S and feeding it to the rear side, and a function of dropping foreign matter such as soil attached to the processing object S.

  Between the pair of cutting device frames 10 on the front side of the first rollers 21 and 22, a feed roller 27 for feeding the processing object S to the first rollers 21 and 22 is supported rotatably. The feed roller 27 has projections 29 provided radially on the rotary shaft 28 and rotates in the direction of arrow A (clockwise). The object to be processed S is supplied from above the feed roller 27 and is pushed out toward the first rollers 21 and 22 by the protrusion 29 of the feed roller 27 that rotates.

  The shredding device 30 is used when the processing object S is cut by the cutting rotor 31 rotatably supported by the cutting device frame 10 on the rear side of the second rollers 23 and 24 and the cutting blade 33 of the cutting rotor 31. A blade receiving roller 40 that exhibits a blade receiving function, a cover 50 that surrounds the cutting rotor 31, and a blower 60 that blows out a piece of the processing object S shredded by the cutting rotor 31 are provided. The cutting rotor 31 rotates in a direction (arrow B direction, down cut direction) for cutting the processing object S conveyed from the conveying device 20 from above to below. As shown in FIG. 4 (side view), a plurality of mounting portions 34 projecting radially are fixed to the outer periphery of the rotary drive shaft 32 of the cutting rotor 31. The plurality of attachment portions 34 are arranged on the outer periphery of the rotary drive shaft 32 at positions where phases gradually shift as they proceed to one side (blower side) in the longitudinal direction of the rotary drive shaft 32. A base portion of the cutting blade 33 is rotatably attached to the attachment portion 34. That is, the cutting blade 33 is a so-called flere type. For this reason, when the cutting rotor 31 rotates in the down cut direction, the fragments of the processing object S present in the rotation trajectory of the cutting blade 33 are continuously affected by the cutting blade 33 whose phase is shifted. .

  The shredding device 30 also has a function of transferring the shredded pieces of the processing object S in addition to the function of shredding the processing object S. That is, the plurality of cutting blades 33 have their respective tips except for the cutting blade 33 ′ disposed at the right end so as to generate an air flow for transferring the shredded processing target S fragments. The part is bent to the left. For this reason, when the cutting rotor 31 rotates, an airflow flowing from the right side to the left side is generated in the cover unit 50, and the fragment of the processing object S moves to the left side of the cover unit 50 together with this airflow.

  The tip of the rotary blade 33 ′ provided at the right end of the rotation drive shaft 32 is bent to the right in the longitudinal direction of the rotation drive shaft 32 as described above. The cutting blade 33 ′ is for cutting the processing object S that has been conveyed in the direction of the right end of the rotary drive shaft 32.

  On the front side of the cutting rotor 31, as shown in FIG. 1B, a receiving blade roller 40 is disposed at a position where the cutting blade 33 opposes the processing object S. That is, the blade receiving roller 40 is disposed between the cutting rotor 31 and the pair of second rotors 23 and 24 and at a position below the processing object S sent out from the conveying device 20. The blade receiving roller 40 includes a rotating shaft 41 that is rotatably supported between the pair of cutting device frames 10 and protrusions (not shown) that are radially attached to the outer periphery of the rotating shaft 41. It rotates in the direction of arrow C (clockwise). For this reason, when the cutting blade 33 that rotates in the down cut direction comes into contact with the processing object S supplied to the cutting rotor 31 by moving the upper position of the receiving roller 40, the lower part of the processing object S becomes the receiving roller. Abutting in a state of being pressed by 40, the tip side of the processing object S is bent and cut upstream (downward) in the rotational direction of the cutting rotor 31 with this contact position as a bending point.

  Here, when the processing object S is cut, the cutting blade 33 cuts the processing object S by hitting it from above. That is, the cutting blade 33 does not cut so as to sandwich the processing object S between the cutting blade 40 and the receiving blade 40. For this reason, the precision of the gap dimension formed between the receiving blade roller 40 and the cutting blade 33 can be lowered. Therefore, maintenance work for adjusting the gap can be facilitated. Moreover, since the blade receiving roller 40 is rotated in a direction in which the processing object S is sent to the shredding device 30 side, the processing object S can be transported to the shredding device 30 more smoothly.

  The blade receiving roller 40 may be rotatably supported without receiving power, or may be supported between the cutting device frames 10 so as not to rotate, in addition to rotating by receiving power. A plurality of protrusions provided on the blade receiving roller 40 may be provided continuously in the longitudinal direction of the rotation axis. Furthermore, the rotating shaft 41 may be formed in a circular shape or a rectangular shape in cross-sectional view.

  As shown in FIG. 2 (side view), the cover portion 50 that surrounds the cutting rotor 31 is a plate-like member that is connected between the inner surfaces of the pair of cutting device frames 10 and is curved in an arc shape. 1 extends to a position near the second roller 24 disposed on the lower side, and the upper end extends to a position above the second roller 23 disposed on the upper side. A box-shaped portion surrounding the cutting rotor 31 shown in FIG. On the front side of the box-shaped portion, a receiving opening for receiving the processing object S conveyed from the conveying device 20 shown in FIG.

  Openings extending in the left-right direction (not shown) are formed in the upper part and the rear upper part of the cover part 50, and cover parts 51 and 52 covering these are attached to these opening parts through hinges so as to be rotatable. ing. Therefore, as shown in FIG. 3 (side view), when these lid portions 51 and 52 are rotated to open the opening, the upper portion of the cutting rotor 31 can be exposed through the opening. For this reason, the maintenance work of the cutting rotor 31 can be facilitated.

  The blower 60 described above is provided on the left side of the shredding device 30. As shown in FIGS. 4, 5A (side view), and FIG. 5B (side view), the blower 60 communicates with a partition plate 75 provided between the shredding device 30 and the blower 60. The holes 76 communicate with each other. The partition plate 75 has a disc shape, and a substantially semicircular communication hole 76 is opened at a lower portion thereof. The partition plate 75 is provided with an opening adjusting portion 80 that can adjust the opening area of the communication hole 76. The opening adjusting portion 80 includes two moving surface members 81 that can move along the surface portion of the partition plate 75, and a rod-shaped guide member 82 that protrudes from both ends of the surface portion of the partition plate 75 and extends toward the moving surface member. It has. The moving surface member 81 has a fan shape, and a long hole 83 that guides the movement of the moving surface portion 81 by inserting the guide member 82 in the center is formed. A male screw portion is formed at the tip of the guide member 82, and the moving surface member 81 is moved to a desired position by screwing and fastening a nut to the male screw portion of the guide member 82 protruding from the long hole 83. It can be fixed to the partition plate 75 in a state. As a result, when the two moving surface members 81 are moved to the upper part of the communication hole 76, the space portion 35 surrounding the cutting rotor 31 and the communication hole 76 opened in a substantially semicircular shape shown in FIG. The space portion 61 in the blower 60 can be in a communication state. Further, when the moving surface member 81 is fixed to the partition plate 75 in a state where the one moving surface member 81 is moved to the center side of the communication hole 76, the communication opened in an oblique semicircular shape shown in FIG. The space portion 35 surrounding the cutting rotor 31 and the space portion 61 in the blower 60 can be brought into communication with each other through the hole 76.

  As shown in FIG. 4, the blower 60 has a frame 62 formed in a box shape with a space 61 therein, and a plurality of air blows on a rotating shaft 64 that is rotatably supported in the frame 62. And a blower rotor 63 provided with blades 65. The rotation shaft 64 of the blower rotor 63 is coaxially connected to the rotation drive shaft 32 of the cutting rotor 31. For this reason, when the cutting rotor 31 rotates, the blower rotor 63 also rotates, and the air in the space 35 that houses the cutting rotor 31 is sucked into the blower 60 through the communication hole of the partition plate 75. Here, a plurality of louvers 85 shown in FIG. 2 are provided on the cutting device frame 10 disposed at the right end of the cutting rotor 31 in order to make it easier to suck the air in the space 35. The louver 85 is formed by pressing the cutting device frame 10, and an intake hole opened downward is formed in the lower part of the deformed portion (side plate). The intake hole may be a through hole formed by punching the cutting device frame 10. In this case, a net-like net is provided in the through hole in order to restrict the fragment from flowing out through the through hole.

  As shown in FIGS. 6A and 6B, an opening 62b is opened at the upper rear side of the curved peripheral plate 62a of the frame body 62 surrounding the blower rotor 63, and the inner surface of the peripheral plate 62a is formed on the inner surface of the peripheral plate 62a. Is attached detachably to an adhesion preventing member 66 for preventing the fragmented processing object S from adhering. The adhesion preventing member 66 is formed of a synthetic resin material (for example, ultra-high molecular weight polyethylene) or a metal material (for example, stainless steel) having a smooth surface. The adhesion preventing portion 66 may be formed by applying a liquid synthetic resin material to the inner surface of the peripheral plate 62a. The adhesion preventing member 66 may be attached to the inner surface of the side plate of the frame body 62, the inner surface of the cover portion 50, the side surface of the partition plate 75, or the like.

  A shooter attachment portion 67 extending upward is attached to the opening 62 b of the blower 60, and a shooter 70 is connected to the upper end portion of the shooter attachment portion 67. As shown in FIGS. 1A and 1B, the shuter 70 extends upward and has an upper end opened. For this reason, the fragments of the processing object S blown out from the blower 60 flow up in the shooter 70, rise, are discharged from the upper end portion of the shooter 70, fall to the outside of the cutting device 1, and are stored in a storage portion (not shown). Is done.

  The cutting device frame 10 includes a power transmission device 90 that transmits power to driving units such as the first rollers 21 and 22, the second rollers 23 and 24, the feed roller 27, the shredding device 30, the blade receiving roller 40, and the blower 60. Is provided. The power transmission device 90 includes an input shaft 91 that inputs power from a power source (not shown) provided separately from the cutting device 1. When power from the power source is input to the input shaft 91, the drive unit is driven. Is configured to do.

  Next, operation | movement of the cutting device 1 of this invention is demonstrated. First, the cutting device 1 is installed at a predetermined position. In addition, the installation position of the cutting device 1 can be installed in arbitrary positions according to the environment of cutting work. Then, power is supplied to the power transmission device 90 to drive driving units such as the shredding device 30 and the blower 60. Then, the processing object S is placed on the feed roller 27. The processing object S placed on the upper part of the feed roller 27 is fed to the pair of first rollers 21 and 22 by the feed roller 27 that rotates. For this reason, the processing object S can be smoothly supplied to the pair of first rollers 21 and 22.

  The processing object S supplied to the first rollers 21 and 22 is sent to the rear side while being sandwiched between them. At this time, the processing object S can be reliably pulled into the apparatus by the protrusions 26 provided on the surfaces of the first rollers 21 and 22, and foreign matter such as soil adhering to the processing object S is bounced off. be able to. For this reason, this foreign material does not accumulate in the conveyance apparatus 20, and the operation | movement of each part of the conveyance apparatus 20 can be made smooth.

  Then, the processing object S that has been transported rearward by the first rollers 21 and 22 and foreign matter has been dropped is transported further rearward by the second rollers 23 and 24 and foreign matter is dropped. For this reason, since the foreign matter such as soil is further removed by the second rollers 23 and 24, the processing object S supplied to the shredding device 30 is in a state where almost no foreign matter is attached to the shredding device 30. An increase in acting load can be prevented in advance.

  Then, the processing object S conveyed by the second rollers 23 and 24 moves above the receiving blade roller 40 and is conveyed into the shredding device 30. Here, since the receiving roller 40 rotates in the direction (arrow C direction) for feeding the processing object S to the shredding device 30 side, the transport of the processing object S to the shredding device 30 side is smoothly performed. Done.

  The processing object S conveyed in the shredding device 30 is cut by the cutting blade 33 of the cutting rotor 31 that rotates in the down cut direction. At this time, when the processing object S is large or hard, the cutting blade 33 rotates with its base as a rotation fulcrum. For this reason, a big impact force does not act on the cutting blade 33, and the lifetime reduction of the cutting blade 33 can be prevented beforehand. Further, since the receiving blade roller 40 is disposed at a position where the cutting blade 33 opposes the processing object S, when the rotating cutting blade 33 comes into contact with the processing object S, the processing object S becomes the receiving roller. The tip side of the processing object S is bent and cut below the cutting rotor 31 (upstream in the rotational direction) with the contact position with 40 as a bending point. For this reason, the cutting length of the processing object S can be made substantially constant. Further, as described above, the cutting blade 33 is not cut so as to sandwich the processing object S between the receiving blade roller 40, and therefore, the gap dimension between the receiving blade roller 40 and the cutting blade 33 is not limited. Accuracy can be lowered. For this reason, the maintenance work for this clearance adjustment becomes unnecessary.

  Here, when the conveyance direction of the processing object S conveyed from the second rotors 23 and 24 is conveyed to the cutting device frame 10 side disposed on the right side of the machine body, the processing object S is bent in the right direction. It is cut by the cutting blade 33 '. That is, even if the processing object S that may not be cut by the cutting blade 33 bent in the left direction is conveyed into the shredding device 30, the processing object S is cut by the cutting blade 33 ′ bent in the right direction. Can be cut off. For this reason, the processing object S conveyed to the shredding device 30 can be shredded generally.

  The fragments of the processing object S shredded by the cutting rotor 31 are continuously acted on by the cutting blade 33 attached at a position where the phase gradually shifts as it advances to the left in the longitudinal direction of the rotary drive shaft 32, and the blower side And the air flow generated by the rotation of the cutting blade 33 moves to the blower 60 side.

  2 is provided with a suction hole in the right cutting device frame 10, so that when the cutting rotor 31 is driven, outside air flows into the shredding device 30 through the suction hole. Then, it flows through the shredding device 30 and is sucked into the blower 60. For this reason, generation | occurrence | production of the airflow which flows into the blower 60 side in the shredding device 30 becomes easy. For this reason, the fragments in the chopped state can be smoothly flowed to the blower 60 side without staying in the chopping device 30.

  The fragments of the processing object S flowing to the blower 60 side flow into the blower 60 through the communication holes 76 of the partition plate 75 shown in FIG. 5A, are discharged from the blower 60, flow through the shooter 70, and externally. To be discharged.

  Here, as shown in FIG. 5A and FIG. 5B, since the partition plate 75 is provided with the opening adjusting portion 80, the position of the moving surface member 81 of the opening adjusting portion 80 is adjusted. Thus, the opening area of the communication hole 76 can be changed. For this reason, it is possible to adjust the inflow amount of fragments of the shredded processing target S flowing into the blower 60, and to restrict the inflow of fragments exceeding the discharge capacity of the blower 60. As a result, it is possible to prevent a situation where fragments are clogged in the blower 60.

  Further, as shown in FIG. 6A, since the adhesion preventing member 66 is provided on the inner side of the peripheral surface 62a of the frame body 62 of the blower 60, it is difficult for the fragments to adhere to the inner surface of the peripheral surface 62a. Yes. For this reason, the situation where a fragment is clogged in the blower 60 can be reliably prevented.

  Next, the operation in the case of performing the remaining trunk processing work of the remaining trunk Z planted in the cocoon U by the remaining trunk processing machine 100 according to the second embodiment will be described. As shown in FIG. 7, first, the remaining trunk processor 100 is attached to the rear portion of the traveling machine body 130, and the traveling machine body 130 is installed at a position where the traveling machine body 130 can straddle the ridge U. Then, the traveling machine body 130 is moved forward along the heel U, and the power from the traveling machine body 130 is transmitted to the input unit 107 of the remaining trunk processor 100. When power is transmitted to the remaining trunk processing machine 100, the excavation rotor 111 rotates in the upcut direction (arrow A direction), and the drive unit of the cutting device 1 such as the feed roller 27 is driven. When the traveling machine body 130 moves forward in such a state, the remaining trunk Z is pushed down toward the front side by the forward movement of the traveling machine body 130, and the root Zn is scooped up from the lower side to the upper side by the digging rotor 111. While being dug up, it is drawn downstream in the rotation direction of the dug claw 113 so that the root Zn precedes. The remaining trunk Z is further drawn into the cutting device 1 by the feed roller 27, transported by the cutting device 1, shredded, discharged from the shooter 70, and stored in the storage unit 120.

  In this way, the remaining trunk Z planted in the basket U is continuously processed along with the forward movement of the traveling machine body 130.

  As described above, since the remaining trunk processing machine 100 according to the second embodiment is mounted with the cutting device 1 described in the first embodiment as it is, the same effect as the cutting device 1, that is, a cutting blade. The remaining of the cutting device 1 is mounted, which prevents the life of the cutting blade 33 from deteriorating, prevents the fragments of the remaining trunk Z from staying in the shredding device 30, and easily adjusts the gap between the cutting blade 33 and the receiving blade roller 40. The stem processor 100 can be provided. Further, as described above, since the cutting device 1 is configured independently of the machine frame 101, the cutting device 1 and the machine frame 101 can be assembled separately, and the assembly work of the remaining trunk processing machine 100 can be easily performed. can do. Furthermore, although the above-described remaining trunk processing machine 100 is of a type that is pulled by the traveling machine body 130, the remaining trunk processing machine itself may be configured to be capable of self-running.
