Description

  The present invention relates to a cutting apparatus, and 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 end, and conveys the processing object so that the end precedes it. The present invention relates to a cutting device that chops and transfers.

  There are a cylinder type and a flywheel type classified by the structure of a cutting part in a cutting apparatus for shredding such a processing object (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 has a plate shape, and is attached along the inner surface such that the blade surface faces inward of a through hole formed in the inner surface of the disk-shaped flywheel. The flywheel-type fixed blade is attached to the base side and is disposed in the vicinity of the fixed blade that rotates. The object to be treated is inserted into the hole of the flywheel and cut while being sandwiched between the rotating rotary blade and the fixed blade.

  As shown in FIG. 1, the shredding device 40 has a plurality of cutting blades 43 extending radially on a rotary drive shaft 42a rotatably supported on the machine frame 10 on the rear side of the second rollers 26 and 27. The cutting rotor 42 and the cover part 44 which covers the cutting rotor 42 are provided. The cutting rotor 42 rotates in a direction (arrow D direction) for cutting the processing object S transported from the transport processing apparatus 20 from above to below.

  The shredding device 40 also has a function of transferring fragments of the shredded processing target S in addition to a function of shredding the processing target S. In other words, the plurality of cutting blades 43 are bent in the same direction on the left side in the same direction so as to generate an air flow for transferring the cut pieces of the processing object. For this reason, when the cutting rotor 42 rotates, an airflow flowing from the right side to the left side is generated in the cover part 44, and the fragment of the processing object S moves to the left side of the cover part 44 together with this airflow. The cutting blade 43 is rotatably connected to an attachment portion 45 whose base is fixed to the rotation drive shaft 42a. That is, the cutting blade 43 is a so-called flail type.

  The cover portion 44 is a plate-like member that is connected between the inner surfaces of the pair of airframe frames 10 and is curved in an arc shape. The cover portion 44 and the airframe frame 10 form a box-shaped portion that surrounds the cutting rotor 42. A receiving opening 47 for receiving the processing object S to be transported in the inside of the cover 44 is opened on the transport processing device 20 side of the box-shaped portion. In addition, an inlet (not shown) through which a fragment of the processing object S transferred along with the air flow generated by the rotational movement of the cutting blade 43 flows into the blower 60 is opened at the left end of the box-shaped portion.

  The blower 60 described above is provided at the left end of the shredding device 40. The blower 60 has a space portion 61 therein and is formed in a box shape. In the space portion 61, a blower rotor 63 including a plurality of blower blades 63 b is provided on a rotation shaft 63 a that is rotatably supported. Yes. The rotation shaft 63a of the blower rotor 63 is coaxially connected to the rotation drive shaft 42a of the cutting rotor 42. For this reason, when the cutting rotor 42 rotates, the blower rotor 63 also rotates. Thus, by arranging the rotation shaft 63a of the blower rotor 63 coaxially with the rotation drive shaft 42a of the cutting rotor 42, the parts can be shared, the entire cutting device can be reduced in size, and inexpensive. Can be.

  The space portion 61 of the blower 60 communicates with the above-described inflow port formed in the shredding device 40, and a discharge port for discharging the fragments transferred into the blower 60 to the shooter 70 (see FIG. The shooter 70 is connected to the discharge port.

  The shuter 70 has a rectangular tube shape, the base side thereof extends in the vertical direction, the upper side is curved in a convex shape, and the upper end portion extends obliquely downward. For this reason, the fragments of the processing object S blown out from the blower 60 flow up in the shooter 70 and are discharged from the upper end portion of the shooter 70. Inside the shuter 70, an adhesion preventing part 71 for preventing adhesion of fragments of the processing object S to be transferred is attached. The adhesion preventing part 71 is formed of a synthetic resin material (for example, ultra-high molecular polyethylene) or a metal material (for example, stainless steel) having a smooth surface. The adhesion preventing portion 71 may be formed by applying a liquid synthetic resin material to the inside of the shooter 70. The shooter 70 may be attached so as to incline in the direction along the blowing direction of the fragments blown out from the blower 60.

  The body frame 10 is provided with a power transmission device 90 that transmits power to the first rollers 23 and 24, the second rollers 26 and 27, the shredding device 40, and the blower 60. 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. The input shaft 91 is rotatably supported by the body frame 10 disposed on the right side of the cutting device 1. When power from a power source is input to the input shaft 91, the power transmission device 90 transmits this power to the first rollers 23 and 24, the second rollers 26 and 27, the shredding device 40, and the blower 60. It has become.

  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, the processing object S is supplied between the pair of first rollers 23 and 24 from the front side of the cutting device 1. The processing object S supplied to the first rollers 23 and 24 is sent out to the rear side while being sandwiched between them. Here, the protrusions 29 provided on the surfaces of the first rollers 23 and 24 abut against the processing object S to be supplied and push it out so as to send it out to the gap 21 between the pair of first rollers 23 and 24. . For this reason, the drawing-in operation of the processing object S by the first rollers 23 and 24 can be made more reliable. In addition, foreign matters such as soil attached to the processing object S can be splashed off by the protrusions 29. The dropped foreign matter such as soil falls and passes between the pair of body frames 10 and falls on the ground or floor where the cutting device 1 is placed. For this reason, this foreign material does not accumulate in the conveyance processing apparatus 20, and the operation | movement of each part of the conveyance processing apparatus 20 can be made smooth.

  Here, when the supplied processing object S is large, when the processing object S is drawn into the gap 21 between the pair of first rollers 23 and 24, the first roller 23 is pressed upward by the processing object S. Thus, the first roller 23 moves upward via the arm member 81 of the roller support device 80. For this reason, the gap 21 between the pair of first rollers 23 and 24 is enlarged, and the processing object S is conveyed between the pair of first rollers 23 and 24 without being clogged. For this reason, the situation where the processing operation of the processing object S is interrupted can be prevented.

  When the first roller 23 moves upward via the arm member 81, the tension spring 85 further extends and biases the processing object S via the first roller 23. For this reason, the processing object S is conveyed while being sandwiched between the pair of first rollers 23 and 24 by the urging force. As a result, the processing object S can be conveyed without the first roller 23 slipping.

  Then, the processing object S that has been transported rearward by the first rollers 23 and 24 and from which foreign matter has been dropped is transported further rearward by the second rollers 26 and 27 and foreign matter is dropped. For this reason, since foreign substances such as soil are further removed by the second rollers 26 and 27, the processing object S supplied to the shredding device 40 is placed in a state in which no foreign matter is attached to the shredding device 40. An increase in acting load can be reliably prevented.

  Then, the processing object S conveyed by the second rollers 26 and 27 is shredded by the cutting rotor 42 of the shredding device 40. Here, when the processing object S conveyed is hard, when the cutting blade 43 comes into contact with the processing object S, the cutting blade 43 rotates with the base as a rotation fulcrum. For this reason, the situation where a big load acts on the cutting blade 43 and the shredding device 40 having the same is prevented, and damage to the cutting blade 43 and the shredding device 40 and a decrease in the life of the cutting blade 43 are prevented. be able to.

  Further, when the cutting rotor 42 rotates, an air flow is generated in the shredding device 40 by the rotation of the cutting blade 43, and the fragment of the processing object S that has been shredded is transferred to the left side of the shredding device 40 together with this air flow. , Flows into the blower 60 through the inlet. Here, since the blower 60 is disposed downstream in the transfer direction of the fragments transferred from the shredding device 40, the fragments transferred from the shredding device 40 can be smoothly guided into the blower 60, It is possible to prevent a situation in which the fragments stay on the way to the blower 60. Further, the cutting blade 43 is rotated with the rotational movement of the rotary drive shaft 42a and operates to cut off the processing object S from above, so that the cutting blade 43 does not come into contact with the cover member 44. As long as it is provided, adjustment of the mounting position of the cutting blade 43 is not necessary. For this reason, the maintenance burden of the shredding device 40 can be reduced.

  The fragments guided into the blower 60 flow through the blower 60, discharge from the discharge port, and flow into the shooter 70. The fragments flowing into the shooter 70 rise along the direction in which the shooter 70 extends, are discharged from the upper end of the shooter 70, and are collected at a predetermined position where the cutting device 1 is installed. Here, since the adhesion preventing portion 71 is formed inside the blower 60, even if the fragment moving in the shooter 70 contacts the inner surface of the shooter, it does not adhere and flows downstream. Therefore, the fragments do not adhere to and stay in the shooter 70 and the flow path in the shooter 70 is not narrowed, and the fragments can be stably transferred.

  As described above, the cutting device 1 according to the present invention transports the processing object S while dropping the foreign matter by the transport processing device 20, chops the processing target object by the shredding device 40, transports it in a predetermined direction, and cuts it. Since the adjustment work of the blade 43 is unnecessary, the cut pieces do not stay in the apparatus and the cutting work is not interrupted, and the cutting work is not interrupted by the adjustment work of the cutting blade 43. For this reason, the cutting device 1 can stably perform a series of operations until the processing object S is supplied and discharged from the shooter 70, and as a result, the work efficiency of the processing operation can be improved. .

  In the present embodiment, the case where the first roller 23 and the second roller 26 arranged on the upper side are movable up and down is shown, but the first roller 24 and the second roller arranged on the lower side are shown. The first roller 24 and the second roller 27 may be vertically movable together with the first roller 23 and the second roller 26. Further, a plurality of pairs of second rollers 26 and 27 may be arranged on the rear side of the pair of first rollers 23 and 24 so as to be arranged in a straight line.

  Further, the above-described adhesion preventing portion 71 may be formed inside the shredding device 40. By forming the adhesion preventing portion 71 inside the shredding device 40 in this way, the shredded processing object S transferred through the shredding device 40 is placed inside the shredding device 40, for example, the cover portion 44. Since it flows to the downstream side in the transfer direction without adhering even if it touches the inside, the fragment of the processing object S that has been shredded adheres to the inside of the shredding device 40 and stays in the shredding device 40. In addition, the fragments can be transferred smoothly.

  Further, as shown in FIG. 3A (plan view) and FIG. 3B (side view), the blower 60 and the shooter 70 may be disposed on the rear side of the shredding device 40.
