Description

  The present invention relates to a roll baler for forming a chopped forage crop into a roll bale.

  The roll baler includes a crawler that is operated by a prime mover disposed on the vehicle body as described in Patent Document 1, and a harvester, a cockpit, a hopper, and a molding chamber that are provided with a chute from the front to the rear of the vehicle body. There are known.

  According to such a roll baler, the forage crop harvested while traveling is shredded, the shredded forage crop is put into the hopper from the chute, and the forage crop falling from the hopper is received on the belt of the conveyor, Rolled veils can be formed by putting the feed crop placed on the forming chamber by means of the transfer rotation of the transfer conveyor.

Japanese Patent Laid-Open No. 2004-321061

  Since the roll baler of the above-mentioned patent document 1 receives and conveys the forage crop dropped from the hopper on the belt of the conveyor, the forage crop that spills from the belt when the forage crop falls falls between the belt and the belt. There is a problem in that the belt enters and adheres to the roller around which the belt is wound, thereby causing a slip on the roller of the belt, and the belt is worn and damaged by the slip.

  In addition, due to spillage of forage crops, the placement of the forage crops on the belt is not uniform, and it is thrown into the molding chamber in a state biased to either the left or right or the center, so that the roll bale to be molded is In addition to the deformed roll veil partially having different densities, there is a problem that the roll bale is likely to be deformed due to a difference in density or deformation.

  In addition, when spilled forage crops accumulate in the aircraft, the deposited forage crops are cleaned, but the various components that make up the self-propelled harvesting roll baler become an obstacle, so the forage crops cannot be cleaned. There is a problem that a part is generated, and there is a problem that a forage crop remains in a part where the cleaning of the forage crop cannot be achieved, and a bad odor due to the decay of the remaining forage crop occurs.

  In particular, when the conveyor is inclined toward the inlet of the molding chamber as in the roll baler of Patent Document 1, this inclination causes the feed crop to slide down from the belt to the upstream side during conveyance. The spillage of feed crops also increases, which not only increases the amount of feed crop that enters between the belt and the roller, but also lowers the transport efficiency, which reduces the forming efficiency of the roll bale. was there.

  This invention makes it an example of a subject to cope with such a problem. That is, it is possible to prevent the feed crops from being spilled out of the machine, to efficiently feed the feed crops, to feed the feed crops in an even state to the molding room, and to leave the feed crops in the machine. Therefore, it is possible to form a normal-shaped roll bale of uniform density and a roll bale that is not easily deformed, and the roll baler can be easily cleaned, and a foul odor caused by residual feed crops in the machine can be prevented. What can be done is an object of the present invention.

  The upper end of the forage crop discharge port 31A is positioned below the upper end of the forage crop inlet 40 of the hopper 4 (the front edge of the top 41) at the lower end position of the harvester 3, The lower end of the discharge port 31 </ b> A is formed in an arc shape so as to be positioned above the lower end of the feed crop input port 40 of the hopper 4 at the upper limit position of the harvester 3.

  Further, the position and direction of the forage crop discharge port 31A vary from the upper limit position (position indicated by the phantom line) to the lower limit position (position indicated by the solid line) of the harvesting machine 3, but regardless of the change in this position and direction. The feed crop B discharged from the feed crop discharge port 31 </ b> A is set in a position and a direction in which the feed crop input port 40 of the hopper 4 can be passed into the hopper 4 so as not to go out of the hopper 4. .

  Further, even if the position and direction of the forage crop discharge port 31 </ b> A change from the upper limit position (position indicated by the phantom line) to the lower limit position (position indicated by the solid line) of the harvester 3, The position and the direction are set so as to contact the tip 40A of the diffusion plate 4A provided on the inner side (inside the hopper 4).

  The upper end of the hopper 4 is closed by a top plate 41, a feed crop input port 40 is opened at the front end, and a feed crop dropping port 42 is opened below. The diffusion plate 4 </ b> A provided inside the top board 41 is disposed in the vicinity of the central portion of the hopper 4 in the left-right direction.

  Even if the position and direction of the forage crop discharge port 31A change in the range from the upper limit position (position indicated by the phantom line) to the lower limit position (position indicated by the solid line) of the harvester 3, the forage crop input port 40 can be The area has a size that does not contact the periphery of the feed crop input port 40.

  The diffusion plate 4A has inclined surfaces 41A and 42A that are inclined so as to expand from the tip 40A to the left and right, and the position of the tip 40A and the length in the vertical direction are from the upper limit position (position indicated by the phantom line) of the harvester 3. Regardless of the change in the position and direction of the feed crop discharge port 31A of the chute 3A accompanying the change in the range of the lower limit position (the position shown by the solid line), the released feed crop B is disposed at the position where it comes into contact and released. The length of the forage crop B to be contacted is set.

  Below the feed crop drop opening 42 of the hopper 4, a transport unit 4 </ b> B is arranged. The transport unit 4 </ b> B includes a feed crop transport space 43 that is an independent space continuous with the feed crop dropping opening 42, and the transport conveyor 5 is disposed in the feed crop transport space 43.

  The forage crop conveyance space 43 is provided with an outlet 430 that reaches the inlet 6A of the molding chamber 6 on the downstream side, and a bottom portion that extends from the lower side of the forage crop drop opening 42 to the outlet 430 is secured as the conveyance surface 431.

  In addition, a guide surface 431 </ b> A that receives the feed crop falling from the feed crop dropping port 42 of the hopper 4 and guides it to the transport surface 431 is connected to the upstream side of the transport surface 431. The guide surface 431A is disposed outside a downstream end portion of an endless track body 52, which will be described later, is coaxial with a rotating body 50, which is described later, and is formed in an arc shape that comes into contact with the tip of a later-described transport protrusion 53. .

  The forage crop conveyance space 43 is formed as an independent space closed from the outside except for the portion communicating with the forage crop dropping opening 42 and the outlet 430, and the forage crop B falling from the forage crop dropping opening 42 is outside the machine. It can be received without spilling.

  The conveyor 5 is arranged such that the upstream end is located below the feed crop dropping port 42 and the downstream end is located so as to reach the outlet 430. The endless track body (chain) 52 is wound around the rotary bodies (sprockets) 50 and 51 that are rotatably supported on the downstream side.

  The plurality of transport protrusions 53 are provided on the outer periphery of the endless track body 52, and the transport protrusion 53 causes the feed crop B to be transported from the guide surface 431A to the transport surface by the transport rotation (in the direction of the arrow) of the endless track body 52. The feed crop B on the transport surface 431 is forcibly transported toward the outlet 430 while being guided to 431.

  The endless track body 52 is composed of two chains wound respectively on the left and right sides. The transport protrusions 53 are bridged over the two endless track bodies 52 and a predetermined distance is set between the adjacent transport protrusions 53. They are arranged at intervals, and in FIG. 2, a ladder shape that is continuous in the conveyance rotation direction is exhibited.

  The conveyance protrusion 53 has a length extending over the endless track body 52 and a protruding length at which the tip comes into contact with the conveyance surface 431 and the guide surface 431A. It is forcibly transported so as to scrape toward 430, and the stagnation of the forage crop B can be prevented on the transport surface 431 and the guide surface 431A.

  Since such a conveyor 5 has a ladder shape, the forage crop B falling from the forage crop dropping opening 42 is removed from the gap formed by the endless track body 52 and the transport protrusion 53 made of two chains. It can be made to fall to the conveyance surface 431 and the guide surface 431A, and the stagnation of the forage crop B on the conveyance conveyor 5 can be prevented now.

  Therefore, all of the feed crop B falling from the feed crop dropping port 42 can be dropped on the transport surface 431 and the guide surface 431A without leaving it on the transport conveyor 5.

  The endless track body 52 of the conveyor 5 is not limited to a chain but may be a belt (not shown). When the endless track body 52 is a belt, the forage crop B falling from the forage crop dropping port 42 is placed on the endless track body 52. The placed forage crop B is transported by the endless track body 52. By rotation, it can be dropped onto the guide surface 431A.

  The molding chamber 6 includes a fixed-side half 60 that is partitioned on the hopper 4 side, a movable-side half 61 that is section-revisioned on the rear side of the fixed-side half 60, a fixed-side half 60, and a movable-side half 61 and a molding device 62 arranged over the same.

  The stationary half 60 is formed with an inlet 6A for feeding the feed crop B conveyed from the conveyor 5 into the molding chamber 6.

  Above the inlet 6A, a delivery device A4 for sending a packing material (net, twain, etc.) B2 for packing the roll bale B1 molded in the molding chamber 6 into the molding chamber 6 is disposed.

  The delivery device A4 is for delivering the packaging material B2 into the molding chamber 6 after the roll bale B1 is molded in the molding chamber 6. The delivered packaging material B2 is a roll that is rotated by the molding operation of the molding device 62. The roll bale B1 is packed so as to be drawn by the bale B1 and wound around the roll bale B1.

  In such a molding chamber 6, the feed crop B introduced into the molding chamber 6 from the transport conveyor 5 through the inlet 6 </ b> A is compressed while being rotated by the molding device 62 to be molded into a cylindrical roll bale B <b> 1. Has been.

  The forming device 62 is arranged so as to be continuous on a circumference extending between the fixed-side half 60 and the movable-side half 61, and includes a plurality of rotating rollers 620 with the left-right direction as an axis, and a lower half of the fixed-side half 60. The forming belt 621 is wound around the rotating roller 620 arranged in the section, and the forming belt 622 is wound around the rotating roller 620 arranged in the lower half of the movable half 61.

  The forming belts 621 and 622 are wound around the roll bale B1 which is expanded in diameter during the forming of the roll bale B1. Along with this, it is deformed so as to swell outward.

  Reference numerals 623 and 624 denote tension rollers for holding the tension of the forming belts 621 and 622, which are arranged on the outer side of the rotating roller 620 and supported so as to slide in the front-rear direction, respectively. On the other hand, an urging force is applied so that tension is always applied.

  In other words, the tension is always applied to the forming belts 621 and 622 from the start of forming the roll bale B1 to the end of forming by the biasing force described above, so that the frictional force generated by the rotation of the forming belts 621 and 622 is applied to the roll bale B1. On the other hand, it can act in equilibrium and efficiently.

  Such a molding chamber 6 forms the roll bale B1 by the molding device 62 and opens the fixed half 60 by opening the movable half 61 after packing the formed roll bale B1 with the packing material B2. (See FIG. 3), the packed roll bale B1 is discharged from the molding chamber 6, and after the roll bale B1 is discharged, the movable side half 61 is closed and the fixed side half 60 is closed. The next roll bale B1 is returned to a state where it can be molded.

  The molding chamber 6 is not limited to the configuration having the molding device 62 formed by combining the illustrated rotating roller 620 and the molding belts 621 and 622, and may include the molding device 62 including the rotating roller 620.

  The discharge support body 7 once supports the roll bale B1 discharged from the fixed side half 60 outside the fixed side half 60, and lowers the roll bale B1 from a low position close to the field G. It is rolled and discharged.

  The discharge support 7 is supported by the vehicle body A1 so that the support 70 is rotatably supported about the left-right direction, the discharge 71 is connected to the rear end of the support 70, and the support 70 is rotated. And a hydraulic cylinder (elevating support device) 72 that supports the stopped state of the support portion 70.

  The lifting / lowering support device is not limited to the illustrated hydraulic cylinder 72, and may be any structure that can support the rotating portion 70 so as to rotate and can support the stopped state of the supporting portion 70.

  In FIG. 2, the support part 70 is pivotally supported on the left and right sides of the vehicle body A <b> 1, and a C-shaped discharge part 71 is continuously provided so as to extend over the two support parts 70.

  As shown in FIG. 3 (roll bale support state, ascent limit position), the discharge portion 71 is a state of the support portion 70 in a state where the shaft is in the front-rear direction (an inclined state in which the tip of the support portion 70 is slightly higher than the horizontal). The roll bale B1 discharged from the fixed-side half 60 is temporarily supported by the support portion 70 and the discharge portion 71 so as to incline in the direction of tilting backward with respect to the shaft.

  That is, when the fixed-side half 60 is opened and the roll bale B1 is discharged, the discharging force is weakened by the inclination of the support part 70, and the discharge part 71 receives the roll bale on the support part 70. B1 can be supported.

  As shown in FIG. 3 (roll bale support state, rising limit position), the hydraulic cylinder 72 maintains a state in which the shaft of the support portion 70 is in the front-rear direction by the extension (a state close to horizontal), and FIG. As shown in FIG. 5 (the discharge middle state) and FIG. 5 (roll bale discharge state, lower limit position), the support portion 70 is gradually lowered by contraction, and the state where the front end side of the support portion 70 is lowered is held. Yes.

  As shown in FIG. 4 (roll bale discharging state) and FIG. 5 (roll bale discharging state, lower limit position), the discharge unit 71 moves the tip of the support unit 70 toward the field G when the support unit 70 is lowered. As the inclination gradually decreases, the tip of the discharge portion 71 inclines so as to gradually decrease toward the field G, and this inclined state is held by the hydraulic cylinder 72.

  That is, the support part 70 and the discharge part 71 are lowered so that the positions of the respective tips gradually lower from the roll bale support state of FIG. 3 to the roll bale discharge state of FIG. By operating, the roll bale B1 can be discharged from the support portion 70 through the discharge portion 71 so as to roll slowly to the field G.

  The inclination angle of the discharge part 71 with respect to the axis of the support part 70 receives the momentum of discharge of the roll bale B1 discharged from the stationary half 60 in the roll bale support state of FIG. 5 is determined within a range of angles at which the roll bale B1 can be discharged so as to roll slowly when the tip of the discharge unit 71 approaches the field G in the roll bale discharge state of FIG. be able to.

  According to the self-propelled harvesting roll baler A configured as described above, the forage crop B in the field G is shredded while being harvested by the harvester 3 while running, and the shredded forage crop B is fed into the forage crop by the chute 3A. It is put into the hopper 4 through the mouth 40.

  The forage crop B in the hopper 4 falls from the forage crop dropping port 42 to the conveying surface 431 of the forage crop conveying space 43, and is directed toward the input port 6 </ b> A by the conveying protrusion 53 that operates along with the conveying rotation of the conveying conveyor 5. The material is conveyed and is introduced into the molding chamber 6 through the insertion port 6A by the conveying projection 53, and further molded into the roll bale B1 by the molding device 62.

  After forming the roll bale B1, the packaging material B2 is sent out from the delivery device A4, and the roll bale B1 is packed, and the fixed half 60 is opened after the roll bale B1 is packed. Is discharged out of the molding chamber 6.

  The discharged roll bale B1 is once supported by the support part 70 and the discharge part 71 of the discharge support body 7, and the supported roll bale B1 is lowered by the lowering of the support part 70 and the discharge part 71 due to the contraction of the hydraulic cylinder 72. G is discharged.

  When the self-propelled harvesting roll baler A is traveling (normal traveling and harvesting traveling), the lower end of the chute 3A is adjacent to the left side of the cockpit 1 and located behind the front end of the cockpit 1 By connecting the crop discharge unit 34 to the feed crop discharge port 31A of the shoot 3A from this portion toward the feed crop input port 40 of the hopper 4, the chute 3A is disposed so as to cross the vehicle body A1 diagonally, thereby Since the left and left visual fields from 1 are not obstructed, accidents due to poor visual field can be prevented.

  Further, the feed crop input port 40 of the hopper 4 faces forward to the front end side of the hopper 4 in a range corresponding to the change in the position and angle of the feed crop discharge port 31A of the chute 3A accompanying the vertical movement of the harvester 3. Therefore, even if the chute 3A moves up and down as the harvester 3 moves up and down, the forage crop B can be reliably put into the hopper 4.

  The upper end of the forage crop discharge port 31A is the lower limit position of the harvester 3 (the position indicated by the solid line in FIG. 1), and the upper end of the forage crop input port 40 of the hopper 4 (the leading edge of the top 41). The lower end of the forage crop discharge port 31A is located above the lower end of the forage crop input port 40 of the hopper 4 at the upper limit position of the harvester 3 (the position indicated by the phantom line in FIG. 1). Since it is formed in such an arc shape, the total height of the self-propelled harvesting roll baler A including the chute 3A can be kept low.

  Thereby, it is possible to prevent the chute 3A from becoming an obstacle during movement between the fields G and the like, and a mechanism for folding the chute 3A during movement can be eliminated.

  Further, the position and direction of the forage crop discharge port 31A are set such that the forage crop B discharged from the forage crop discharge port 31A does not reach the outside of the hopper 4 but passes through the forage crop input port 40 of the hopper 4 and enters the hopper. Since it is set in the position and direction where it can be input, the forage crop B can be reliably input into the hopper 4 even if the harvester 3 moves up and down.

  Further, even if the position and direction of the forage crop discharge port 31A change from the upper limit position (the position indicated by the phantom line in FIG. 1) to the lower limit position (the position indicated by the solid line in FIG. 1) of the harvester 3, the hopper 4 is set at a position and a direction in contact with the front end 40A of the diffusion plate 4A provided inside the top board 41 (inside the hopper 4).

  Further, the area of the forage crop inlet 40 is changed even if the position and direction of the forage crop discharge port 31A are changed in the range from the upper limit position (the position indicated by the phantom line) to the lower limit position (the position indicated by the solid line) of the harvester 3. The chute 3A has an area that does not contact the periphery of the feed crop input port 40.

  The length of the tip 40A of the diffusion plate 4A is discharged regardless of the change in the position and direction of the feed crop discharge port 31A of the chute 3A accompanying the change from the upper limit position to the lower limit position of the harvester 3. The crop B is in contact with the length.

  Therefore, the forage crop B introduced into the hopper 4 can be reliably brought into contact with the tip 40A of the diffusion plate 4A, so that the forage crop B can be reliably diffused in the hopper 4 and the hopper 4 The feed crop B can be evenly stored in the hopper 4 without being biased to the central portion or left and right of the hopper 4.

  Thereby, it can drop equally with respect to the forage crop conveyance space 43, without biasing to a center part or right and left.

  Since the forage crop B can be evenly dropped in the forage crop transport space 43 without being biased to the center or left and right, the forage crop B can be transported to the molding chamber 6 in this uniform state.

  As a result, the roll veil B1 formed in the forming chamber 6 can be formed into a normal cylindrical shape with a uniform density and hardly deformed.

  Moreover, even if the position and direction of the forage crop discharge port 31A change from the upper limit position (the position indicated by the phantom line) to the lower limit position (the position indicated by the solid line) of the harvesting machine 3, the chute 3A is used as the forage crop input port 40. Therefore, even if the harvester 3 moves up and down, damage to the chute 3A and the feed crop input port 40 can be prevented.

  A feed crop transport space 43 that is a space continuous with the feed crop drop port 42 is provided below the feed crop drop port 42, and the feed conveyor 5 is disposed in the feed crop transport space 43. The crop B can be conveyed to the molding chamber 6 without spilling out of the machine.

  Further, the forage crop conveyance space 43 is formed as an independent space closed from the outside except for the portion communicating with the forage crop dropping opening 42 and the outlet 430, so that the forage crop falling from the forage crop dropping opening 42 is formed. B can be received without spilling out of the machine.

  Further, the forage crop B that has fallen into the forage crop conveyance space 43 reaches the conveyance surface 431 and the guide surface 431A, and the conveyance protrusion 53 that protrudes from the outer periphery of the endless track body 52 of the conveyance conveyor 5 has the conveyance surface 431 and the guide. The forage crop B reaching the surface 431A can be transported toward the outlet 430 so as to be scraped off by the transport rotation of the endless track body 52.

  Therefore, the forage crop B can be efficiently and reliably charged into the molding chamber 6, and the molding operation of the roll bale B1 can thereby be performed efficiently and reliably.

  Moreover, since the feed protrusion 53 transports the feed crop B reaching the transport surface 431 and the guide surface 431A toward the outlet 430 so as to be scraped off by the transport rotation of the endless track body 52, the transport surface 431 of the feed crop B. In addition, the residual amount on the guide surface 431A can be significantly reduced, whereby cleaning after the work can be easily performed and the generation of malodor due to the residual feed crop B can be suppressed.

  The roll bale B1 discharged from the fixed-side half 60 of the molding chamber 6 is once supported and supported by the support part 70 and the discharge part 71 of the discharge support 7 on the outside of the fixed-side half 60. By rotating the support part 70 and the discharge part 71 in directions in which the respective tips approach the field G by contraction of the cylinder 72, the roll bale B1 can be lowered while being supported.

  And the support part 70 and the discharge | emission part 71 incline so that roll bale B1 can be rolled and discharged | emitted to the field G gradually by descent | fall, and roll bale from the low position (descent | fall limit position) close to the field G B1 can be rolled and discharged, so that the drop shock to the roll bale B1 when the roll bale B1 is discharged can be mitigated, and the roll bale B1 can be prevented from being deformed by the drop shock, and the mold can be deformed. The spillage of the forage crop B into the field G can be prevented.
