JP-A-10-257810

  The crop is continuously conveyed by the holding and conveying unit. For this reason, there is a possibility that some of the crops that are continuously conveyed may not change their posture properly.

  An object of the present invention is to provide a harvester that can relatively reliably change the attitude of a continuously transported crop.

The harvester of the present invention is a clamping transport unit that continuously transports rearward while clamping a crop taken in from a field, and a crop transported by the clamping transport unit, further changing the posture of the crop further rearward. A posture changing conveyance unit that continuously conveys the crop, wherein the posture change conveyance unit crops the crop by an upper conveyance unit that sends out the upper part of the crop to one of left and right and a lower conveyance unit that sends out the lower part of the crop to the other of the left and right. While changing the posture of the crop, the crop is transported rearward, and the lower transport unit rotates one of the two rotating members around which the contact member is wound, with the contact member being an endless belt-shaped member. In this way, the two rotating members are moved to the other of the left and right and backward while being in contact with the lower part of the crop along the periphery of the two rotating members, and one of the two rotating members is smaller in diameter than the other, and the other. It is disposed more forward

  According to the harvester of the present invention, the posture changing conveyance unit sends out the upper part and the lower part of the crop in directions opposite to each other in the left-right direction. As a result, the posture of the crop can be changed to a posture lying sideways with respect to the original posture. On the other hand, the delivery conveyor of Patent Document 1 moves only rearward, and does not move in the left-right direction of the machine. Therefore, it is considered that only the delivery body disposed above the nipping / conveying unit contributes to the action of changing the posture of the crop. That is, it is considered that the posture of the crop is changed by acting on only the upper part of the crop. On the other hand, according to the present invention, by sending the upper part and the lower part of the crop in opposite directions, the posture of the crop can be relatively reliably changed.

Moreover, the crop can be sent out to the other of the left and right by the contact member. Further, the contact member is formed in a belt shape, and is wound around the rotating member. Therefore, by adjusting the position and size of the rotating member, the moving direction of the contact member can be easily adjusted. Further, the moving direction of the contact member can be adjusted by adjusting the diameter of the rotating member.

In another aspect, the harvester of the present invention is a clamping conveyance unit that continuously conveys rearward while clamping a crop taken from a field, and changes the posture of the crop conveyed by the clamping conveyance unit. And a posture changing conveyance unit that conveys continuously further rearward, wherein the sandwiching conveyance unit includes a rotation member provided at a front part thereof, a rotation member provided at a rear part thereof, and these two rotation members. Endless belt-shaped members wound around are provided in a pair on the left and right, and the posture changing transport unit contacts the first contact member to the upper part of the crop, and at the rear of the nipping transport unit in plan view. An upper transport unit that sends the upper part of the crop to one of the left and right sides by moving the crop unit to the rear and one of the left and right sides so as to pass near the region sandwiched by the pair of rotating members provided on the left and right; Contact member at bottom of crop While contact, so as to pass through the vicinity region in a plan view, by moving toward the rear and the left and right of the other, and a lower conveying section for feeding the lower part of the crop to the other of the left and right.

Note that the front, rear, left, and right directions in the present specification are directions viewed from a person facing the forward direction of the thin harvester 1. The light load harvesting machine 1 is a machine that harvests light loads with foliage grown in the field while traveling in the field. As shown in FIGS. 1 and 2, the thin harvester 1 includes a nipping / conveying unit 10 that conveys a thin package with foliage and leaves, and cutters 8 </ b> L and 8 </ b> R provided below a front part of the nipping / conveying unit 10. The crop scraping unit 20, the driver's seat 30, the step 31, and the thin load transported by the nipping transport unit 10 provided in front of the nipping transport unit 10 are transported further backward while changing the attitude of the thin load. The transporting unit 100 includes a posture changing transport unit 100, a crop loading unit 40 on which a thin load transported from the attitude changing transport unit 100 is placed, and a traveling unit 50.

  As shown in FIGS. 1 and 2, the nipping and conveying unit 10 extends rearward and obliquely upward from a position near the ground in the field at the front of the thin harvester 1. FIG. 1 shows the nipping and conveying unit 10 with the outer cover provided, and FIG. 2 shows the nipping and conveying unit 10 with the outer cover removed. The nipping and conveying unit 10 includes frames 11L and 11R, conveying belts 12L and 12R, drive pulleys 13L and 13R, and driven pulleys 14L and 14R. Each of these components is provided in a pair on the left and right. Hereinafter, in the reference numerals indicating the configurations provided in the left and right pairs, those with an L indicate the left side configuration of the left and right pair, and those with the R indicate the right side configuration of the left and right pair.

  The drive pulleys 13L and 13R are both disposed at the rear of the nipping and transporting unit 10, and are adjacent to each other in the left-right direction. The driven pulleys 14L and 14R are both disposed at the front of the nipping and transporting unit 10, and are adjacent to each other in the left-right direction. The driving pulley 13L and the driven pulley 14L are rotatably supported by a front portion and a rear portion of a frame 11L that is elongated in the front-rear direction. An endless transport belt 12L is wound around the driving pulley 13L and the driven pulley 14L. The transport belt 12L is pressed against the transport belt 12R by a plurality of pulleys 15L. The driving pulley 13R and the driven pulley 14R are rotatably supported by a front portion and a rear portion of a frame 11R that is elongated in the front-rear direction. An endless transport belt 12R is wound around the driving pulley 13R and the driven pulley 14R. The transport belt 12R is pressed against the transport belt 12L by a plurality of pulleys 15R.

  The driving mechanism 60 that drives the driving pulleys 13L and 13R is provided in the nipping and conveying unit 10. The drive mechanism 60 has a drive motor 61, sprockets 62L and 62R, a motor box 63, chains 64L and 64R, and sprockets 71 to 78. The drive motor 61 is, for example, a hydraulic drive type motor. The rotational movement of the shaft of the drive motor 61 is transmitted to each of the sprockets 62L and 62R via a transmission mechanism provided in the motor box 63. This causes the sprockets 62L and 62R to rotate.

  The sprockets 71 to 78 are rotatably supported by the frames 11L and 11R. Sprocket 73 has a common axis with drive pulley 13R, and sprocket 78 has a common axis with drive pulley 13L. A chain 64L is hung on the sprocket 62L and the sprockets 74 to 78. When the sprocket 62L rotates, the rotational motion is transmitted to the sprockets 74 to 78 via the chain 64L, and the sprockets 74 to 78 also rotate. When the sprocket 78 rotates, the drive pulley 13L rotates. When the drive pulley 13L rotates, the conveyor belt 12L travels along the peripheral edges of the drive pulley 13L and the driven pulley 14L in conjunction with this rotation, and the driven pulley 14L rotates. The transport belt 12L runs clockwise in FIG. A chain 64R is hung on the sprocket 62R and the sprockets 71 to 73. When the sprocket 62R rotates, the rotational motion is transmitted to the sprockets 71 to 73 via the chain 64R, and the sprockets 71 to 73 also rotate. As the sprocket 73 rotates, the drive pulley 13R rotates. When the driving pulley 13R rotates, the conveyor belt 12R travels along the periphery of the driving pulley 13R and the driven pulley 14R in conjunction with this rotation, and the driven pulley 14R rotates. The transport belt 12R runs counterclockwise in FIG.

  As shown in FIGS. 1 and 2, the crop scraping unit 20 includes scraping belts 21L and 21R, rear pulleys 22L and 22R, front pulleys 23L and 23R, and frames 25L and 25R. . Each of these components is provided in a pair on the left and right. The rear pulley 22L has a common axis with the driven pulley 14L of the nipping and conveying unit 10, and rotates in conjunction with the driven pulley 14L. The rear pulley 22R has a common axis with the driven pulley 14R of the nipping and conveying unit 10, and rotates in conjunction with the driven pulley 14R. The front pulley 23L is disposed diagonally to the front left of the rear pulley 22L, and the front pulley 23R is disposed diagonally to the front right of the rear pulley 22R. The front pulleys 23L and 23R are supported by the frames 25L and 25R, respectively.

  An endless scraping belt 21L is wound around the rear pulley 22L and the front pulley 23L, and an endless scraping belt 21R is wound around the rear pulley 22R and the front pulley 23R. Each of the scraping belts 21L and 21R is formed with a plurality of protrusions 21x protruding laterally. When the rear pulley 22L rotates in conjunction with the driven pulley 14L, the squeezing belt 21L further travels along the peripheral edges of the rear pulley 22L and the front pulley 23L, and the front pulley 23L also rotates. The scraping belt 21L runs clockwise in FIG. When the rear pulley 22R rotates in conjunction with the driven pulley 14R, further in conjunction with this, the scraping belt 21R travels along the peripheral edges of the rear pulley 22R and the front pulley 23R, and the front pulley 23R rotates. The scraping belt 21R runs counterclockwise in FIG.

  A pair of right and left cutters 8L and 8R are provided below the front part of the nipping and conveying unit 10. The cutters 8L and 8R are driven and rotated by a motor (not shown). The cutters 8L and 8R cut the thin loads that have grown in the field at their bases. Further, a tire 9 is provided on the right side of the front part of the nipping and transporting section 10. The cutters 8 </ b> L and 8 </ b> R and the tire 9 are all supported at the front of the nipping and conveying unit 10. The tire 9 rotates while touching the ground when the light harvester 1 travels in the field. If there is unevenness in the field, the tire 9 also moves up and down according to the unevenness. Then, the front portion of the nipping and conveying unit 10 also moves up and down in conjunction with the up and down movement of the tire 9.

  The posture changing transport unit 100 is arranged near the rear of the nipping transport unit 10. As shown in FIGS. 1, 3, and 4, the attitude changing transport unit 100 includes an upper transport unit 110 disposed above a rear portion of the nipping transport unit 10, and a lower transport unit disposed below a rear portion of the nipping transport unit 10. And a transport unit 120.

  As shown in FIGS. 1, 3, and 4, the upper transport section 110 includes a cover 110a, a driving pulley 111, a driven pulley 112, a belt 113 with projections, sprockets 115 and 116, and a chain 117. In FIG. 3, the illustration of the configuration of the drive mechanism 60 other than the sprocket 72 is omitted. FIGS. 3 and 4 show the configuration of the upper transport unit 110 with the cover 110a removed. Sprocket 115 is arranged above sprocket 72. The rotation shaft of the sprocket 115 is connected to the rotation shaft of the sprocket 72 via a universal joint 118. Universal joint 118 transmits the rotational movement of sprocket 72 to sprocket 115. The sprocket 116 has a common shaft with the driving pulley 111. An endless chain 117 is wound around the sprockets 115 and 116. As described above, when the drive mechanism 60 drives the drive pulleys 13L and 13R, the sprocket 72 also rotates. When the sprocket 72 rotates, the rotational motion is transmitted to the driving pulley 111 via the universal joint 118, the sprocket 115, the chain 117, and the sprocket 116. Thus, the drive pulley 111 rotates in the direction D1 in FIG.

  The driving pulley 111 is arranged behind the driving pulley 13L in a plan view, as shown in FIG. The driven pulley 112 is disposed in front of the drive pulley 13R and to the right of the drive pulley 13R in plan view. The endless belt-like belt with projection 113 is wound around the driving pulley 111 and the driven pulley 112. The projection-attached belt 113 is provided with a plurality of projections 113x. The protrusion 113x is configured to be foldable with respect to the belt main body. When the driving pulley 111 rotates in the direction D1 in FIG. 3, the belt 113 with projections travels in the directions D2 and D3 in FIG. 3 in conjunction with this, and the driven pulley 112 rotates in the direction D4. That is, the belt with projections 113 runs counterclockwise in FIG. The portion of the belt with projections 113 running in the direction D3 passes in the vicinity of an area α in FIG. 3 sandwiched between the driving pulley 13L and the driving pulley 13R in the left-right direction in plan view. The upper transport unit 110 is configured such that the belt with projections 113 travels at a speed higher than the traveling speed of the chain 123 with projections in the lower transport unit 120 described later. The speed at this time indicates the distance that the chain or the belt moves per unit time.

  The protrusion 113x protrudes toward the side of the belt main body when moving in the D3 direction along with the movement of the belt with protrusion 113. When the protrusion 113x reaches the drive pulley 111, the protrusion 113x is folded so as to be drawn into the cover 110a as the protrusion belt 113 moves in the direction D1. The projection 113x assumes a folded state when it moves along the direction D2 with the movement of the belt 113 with the projection. When the belt 113 with a projection reaches the driven pulley 112, the projection 113x jumps out from the inside of the cover 110a to the outside as the belt 113 moves in the D4 direction, and again faces the side of the belt body. Protrude.

  The lower transport section 120 has a sprocket 121 and a sprocket 122 (two rotating members), and a chain 123 with a projection (a contact member). The sprocket 121 is arranged below the sprocket 77 as shown in FIG. The rotation shaft of the sprocket 121 is connected to the rotation shaft of the sprocket 77 via a universal joint 125. As described above, when the drive mechanism 60 drives the drive pulleys 13L and 13R, the sprocket 77 also rotates. Universal joint 125 transmits the rotational movement of sprocket 77 to sprocket 121. As shown in FIG. 3, the sprocket 121 is disposed in front of the driving pulley 13L in a plan view. The sprocket 122 is arranged behind the driving pulley 13L. The diameter of the sprocket 122 is larger than the diameter of the sprocket 121. The endless chain 123 with projections is wound around the sprocket 121 and the sprocket 122. A plurality of protrusions 123x that protrude laterally are formed on the chain 123 with protrusions. When the sprocket 121 rotates, the chain with projections 123 travels along the periphery of the sprockets 121 and 122 in conjunction with this, and travels in the E1 direction and the E2 direction. That is, the chain 123 with projections runs clockwise in FIG. Since the diameter of the sprocket 122 is larger than the diameter of the sprocket 121, the E1 direction is inclined in both the front-rear direction and the left-right direction in plan view. Similarly, the E2 direction is also inclined in both the front-back direction and the left-right direction in plan view. As a result, the portion of the chain with projections 123 running along the E1 direction moves to the right while moving forward. In addition, the part traveling along the E2 direction moves to the right while moving backward. Further, the portion of the chain 123 with protrusions that runs along the E2 direction passes in the vicinity of the area α in FIG.

  Two guides 126 are provided at the rear of the lower transport unit 120. As shown in FIG. 4, one guide 126 is located slightly above sprocket 122 and the other guide 126 is located slightly below sprocket 122. As shown in FIG. 3, the substantially right half of the guide 126 extends horizontally from the right end of the sprocket 122 to the rear end of the sprocket 122 along the periphery of the sprocket 122 in a plan view. A substantially left half of the guide 126 extends horizontally toward the left.

  The crop placing section 40 is provided at a position slightly to the left behind the nipping transport section 10 as shown in FIG. 3 and below the lower transport section 120 as shown in FIG. The crop placing section 40 has a driving roller 42 and a driven roller 43 (see FIG. 1), and a transport belt 41 wound around these rollers. The drive roller 42 is driven and rotated by a motor (not shown). Thereby, the transport belt 41 runs in the F direction in FIG. As will be described later, a thin load harvested from the rear of the nipping and transporting unit 10 falls on the transport belt 41. The crop placing section 40 conveys the thin load backward.

  As shown in FIG. 1, the step 31 is provided at a position behind the driver's seat 30 and on the right side of the crop placing section 40. On the step 31, a container for accommodating the harvested thin goods is installed, and an operator boards. The operator takes in the harvested light load from the crop mounting part 40 and stores it in a container.

  The traveling unit 50 is provided at a lower portion of the thin harvester 1 and has a crawler that moves the thin harvester 1. The driver's seat 30 is provided on the right side near the center in the front-rear direction of the thin harvester 1 and has an operation unit for operating the traveling unit 50 and the like and a seat on which a pilot sits. The operator operates the operation unit while sitting on the seat to move the thin harvester 1 forward and backward, or to turn left and right.

  Hereinafter, a method of harvesting a thin load by the thin load harvester 1 will be described. When the drive mechanism 60 drives the drive pulleys 13L and 13R in the nipping and transporting section 10, the transport belt 12L travels clockwise in FIG. 2 and the transport belt 12R travels counterclockwise in FIG. In conjunction with this, in the crop scraping unit 20, the scraping belt 21L rotates clockwise in FIG. 2, and the scraping belt 21R rotates counterclockwise in FIG. When the operator boarding the light load harvester 1 advances the light load harvester 1 toward the row of light loads growing on the field, the scraping belts 21L and 21R scrape the light loads to the front of the nipping and conveying unit 10. Induce. The guided thin load is cut from the root by the cutters 8L and 8R while being sandwiched between the transport belt 12L and the transport belt 12R at the front portion of the nipping transport unit 10. The cut thin load is conveyed to the rear part of the nipping and conveying unit 10 while being nipped by the conveying belts 12L and 12R in a vertically extending posture (see FIG. 4). When the thin harvester 1 is moved forward along the rows of thin loads, the plurality of thin loads arranged along the rows are sequentially cut by the cutters 8L and 8R, and are continuously transported by the sandwiching transport unit 10.

  On the other hand, when the drive mechanism 60 drives the drive pulleys 13L and 13R, the rotational motion of the sprockets 72 and 77 is transmitted to the sprocket 115 of the upper transport unit 110 and the sprocket 121 of the lower transport unit 120 as described above. Thereby, the belt 113 with projections travels in the directions D1 to D4 shown in FIG. 3, and the chain 123 with projections travels in directions E1 and E2 shown in FIG. The upper portion of the thin load conveyed to the rear of the nipping and conveying unit 10 comes into contact with a portion of the belt with projections 113 traveling in the direction D3. The projection 113x provided in this portion moves in the direction D3 with the movement of the belt 113 with the projection. Therefore, the upper portion of the thin load is sent out in the D3 direction while being caught and scraped by the protrusion 113x. On the other hand, the lower part of the thin load conveyed to the rear part of the nipping conveyance unit 10 comes into contact with a portion of the chain 123 with projections that runs in the E2 direction. The projection 123x provided in this portion moves in the E2 direction with the movement of the chain 123 with the projection. Therefore, the lower portion of the thin load is sent out in the E2 direction while being caught and raked by the protrusion 123x. The guide 126 separates the thin load that is caught by the protrusion 123x and moves together with the chain 123 with protrusion from the protrusion 123x on the way. This prevents a thin load from being dragged by the protruding chain 123 longer than necessary.

  As described above, the upper portion of the thin load is sent out by the upper transport section 110 in the direction D3, that is, diagonally to the left, and the lower portion of the thin load is sent out by the lower transport section 120 in the direction E2, that is, diagonally to the right. As a result, the thin load is continuously transported rearward while lying down so that the upper portion is disposed on the left side and the lower portion is disposed on the right side. Then, it falls onto the transport belt 41 of the crop placing section 40 arranged below the lower transport section 120. The crop placing section 40 transports the overturned thin load further rearward. The worker on the step 31 collects the thin loads transported by the crop mounting part 40 in a sideways state and stores them in the container on the step 31.

  According to the present embodiment described above, the posture changing conveyance unit 100 changes the posture of the thin load to the posture of lying down with respect to the original posture. The top of the sheer load is located on the left and the bottom is on the right. That is, any of the thin loads is placed on the crop mounting portion 40 while lying down in the same direction. Therefore, the worker can easily accommodate the thin load in the container from the crop mounting portion 40 while keeping the posture. Further, the upper transport unit 110 sends out the upper part of the thin load to the left rear and the lower part to the right rear. As described above, since the upper portion and the lower portion of the thin load are sent out in opposite directions, the attitude of the thin load can be relatively reliably changed.

  Further, the lower conveying section 120 is configured by winding an endless belt-shaped chain with projections 123 around the sprockets 121 and 122. This makes it possible to easily adjust the moving direction of the chain with projections 123 by adjusting the positions and sizes of the sprockets 121 and 122. In fact, the sprocket 121 has a smaller diameter than the sprocket 122 and is disposed forward of the sprocket 122. Thus, the lower transport unit 120 is configured so that the chain with projection 123 moves obliquely rightward and backward along the direction E2.

  Further, when the thin harvester 1 travels in the field, the front part of the nipping and transporting unit 10 and the cutters 8L and 8R also move up and down following the up and down movement of the tire 9. For this reason, even if the field has irregularities, the cutters 8L and 8R also move up and down accordingly. Therefore, based on the height of the ground in the field, the cutters 8L and 8R can cut the thin load at the same height, and the height at which the front portion of the nipping and conveying unit 10 holds the thin load becomes the same.

<Modification>
The above is a description of a preferred embodiment of the present invention. However, the present invention is not limited to the above-described embodiment, and various changes may be made within the scope described in the means for solving the problem. It is possible.

  For example, in the above-described embodiment, the traveling unit 50 has a configuration including a crawler, but may have a configuration including wheels.

  Further, in the above-described embodiment, the cutters 8L and 8R cut the thin load that has grown on the field, thereby taking the thin load from the field. However, instead of the cutters 8L and 8R, a device that pulls in a thin load from the field by pulling it out of the field may be provided.

  In the above-described embodiment, the upper transport unit 110 sends the upper part of the thin load diagonally to the left and the lower transport unit 120 sends the lower part of the thin load diagonally to the right and the rear. However, the right and left directions in which these transport units send out the thin loads may be reversed. That is, the upper transport unit 110 may send the upper portion of the thin load diagonally to the right and the lower transport unit 120 may send the lower portion of the thin load diagonally to the left and the rear.

  Further, in the above-described embodiment, the lower part of the thin load is sent obliquely rightward and backward by moving the chain with projections 123 along the direction E2 while making contact with the lower part of the thin load. However, the lower part of the thin load may be sent to the right rear by other methods. For example, a disk with projections may be rotated, and thin loads may be sent out to the right rear by the projections.

  In the above-described embodiment, the diameter of the sprocket 121 is made different from that of the sprocket 122 so that the chain 123 with a projection is driven obliquely rightward and backward along the direction E2. However, by arranging sprockets of the same diameter in the front and rear, and arranging the rear sprocket on the right side of the front sprocket, the chain 123 with projections wound around these sprockets may run obliquely right rearward.

  Further, the above-described embodiment is an example in which the present invention is applied to harvest of a small load. The present invention may be applied to other crops. For example, it may be applied to harvest of mugwort or leek.
