  First, the whole structure of the vegetable harvester 1 is demonstrated using FIG. 1 thru | or FIG. 1 is a front perspective view of the vegetable harvesting machine, FIG. 2 is a plan view, FIG. 3 is a rear view, and FIG. 4 is a right side view. In the following description, the advancing direction of the aircraft is the front-rear direction, the direction perpendicular to the aircraft advancing direction in plan view is the left-right direction, and the direction is perpendicular to the advancing direction in side view. Is the vertical direction.

  The vegetable harvesting machine 1 according to the present embodiment is configured as a self-propelled type equipped with an engine. The crawler traveling device 2 is driven to advance the machine body along the fence while being pulled out from the basket and placed on the basket. The picked vegetables are picked up and stored in the container 80. In the vegetable harvesting machine 1, the scraping unit 3 is disposed in the foremost part of the machine body, and the front part of the vegetable transport unit 4 is disposed below the scraping unit 3. And this vegetable conveyance part 4 is formed in the height before and behind, and conveys a crop diagonally back. A sorting unit 6 is disposed below the last part. A container transport unit 7 is disposed below the sorting unit 6. In this configuration, an example in which onions are harvested as vegetables will be described, but vegetables such as potatoes and carrots that have been dug up can also be harvested. The onion (harvested product) is scraped by the scraping unit 3, transferred to the vegetable transport unit 4, and transported backward by the vegetable transport unit 4. The onion transported to the end of the vegetable transport unit 4 is transferred to the sorting unit 6, and after being sorted by the sorting unit 6, is stored in a container 80 set on the container transport base 71 of the container transport unit 7. .

  19 and 20, the crawler traveling device 2 includes a drive sprocket 101, a driven sprocket 102, rolling wheels 103, 103, 103, a crawler belt 104, a track frame 105, a lifting mechanism 106, and the like. The lower part of the crawler type traveling devices 2 and 2 can be moved up and down so that the main body of the vegetable harvesting machine 1 can be kept horizontal. In other words, the crawler type traveling device 2 on the left and right side will be described. The other ends of the links 107 and 107 are fixed to fulcrum shafts 108 and 108, and the fulcrum shafts 108 and 108 are pivotally supported on the body frame 5. One end (lower end) of an arm 109 is fixed to one (rear) fulcrum shaft 108, and a long hole 109a is opened on the other side of the arm 109. The piston rod tip of the hydraulic cylinder 110 is inserted into the long hole 109a. The hydraulic cylinder 110 is fixed to the body frame 5 in a substantially horizontal direction in the front-rear direction.

  The hydraulic cylinder 110 is configured to be able to extend and contract the hydraulic cylinder 110 by switching the oil supply direction of the pressure oil by switching the control valve 111 formed of an electromagnetic valve. The control valve 111 is connected to a controller 112, and the controller 112 is connected to an angle setter 113 and an angle sensor 114 disposed at an arbitrary position of the vegetable harvester 1 (the machine frame 5 in this embodiment). The angle setting unit 113 is disposed in the operation unit 90.

  In such a configuration, by setting the angle of the machine body to a horizontal or a desired angle by the angle setting unit 113, there is unevenness when the crawler type traveling device 2 or 2 travels between the furrows during the work. Even if it is tilted, the angle sensor 114 detects the tilt in the left-right direction and lifts the hydraulic cylinder 110 so as to lift the track frame 105 on the lower left and right sides of the aircraft or to lower the track frame 105 on the higher left and right sides. It is configured to be driven to extend or contract to maintain the aircraft at a set angle. That is, when the crawler reaches the convex portion of the ground surface, the airframe is lifted, and as shown in FIG. 19, the hydraulic cylinder 110 is extended and the track frame 105 is lifted to lower the airframe so that it becomes horizontal. On the contrary, when reaching the recess, as shown in FIG. 20, the hydraulic cylinder 110 is reduced, the track frame 105 is lowered, and the airframe is raised to be horizontal. In this way, the raking part 3 and the vegetable conveying part 4 are inclined according to the inclination of the upper surface of the rice cake so that the onion can be surely picked up.

  Further, as shown in FIG. 4, a rotation support portion 9 is provided on the upper part of the left and right support columns 8 erected in the front and rear halfway portion of the machine body frame 5. The rear end portions of the left and right drive cases 49 of the device 40 are pivotally supported, and the conveying device 40 is extended obliquely downward. A hydraulic cylinder 41 is pivotally connected between the drive case 49 of the conveying device 40 and the body frame 5, and the hydraulic cylinder 41 is expanded and contracted to move the conveying device 40 up and down with the rotation support portion 9 as a fulcrum. It can be rotated in the direction so that the height can be adjusted.

  And the height setting apparatus 11 is provided so that the height of the front-end | tip of the conveying apparatus 40 can be set corresponding to the height of the cage | basket | work which performs work. As shown in FIG. 4, the height setting device 11 is provided at the front portion of the machine body frame 5 so as to be a hit when the conveying device 40 is lowered. That is, the height setting device 11 is arranged on both sides or one side of the front part of the machine body frame 5 so that the lower part of the front part of the drive case 49 of the transport device 40 is in contact. And then the height of the height setting device 11 is adjusted so as to match the height of the upper surface of the heel, the conveying device 40 is lowered, and the lower portion of the drive case 49 contacts the height adjusting device 11. Let A contact plate 17 that contacts the upper end of the height adjusting device 11 is provided on the lower surface of the drive case 49. In this way, the front part of the conveying device 40 and the scraping part 3 are adapted to the height of the ridge, so that the front part of the conveying device 40 does not thrust into the soil during the work.

  A specific configuration of the height adjusting device 11 is constituted by a boss body 12 and a screw body 13 screwed to the boss body 12, and a lower portion of the boss body 12 is fixed to a support shaft 14. It is pivotally supported by the body frame 5 and can be rotated back and forth. An operating arm 15 projects from the support shaft 14, and an operating rod 16 is connected to the operating arm 15, and the operating rod 16 is connected to an operating lever (not shown) provided in the operating unit 90.

  With this configuration, the height of the upper end of the screw body 13 can be adjusted to a desired height by rotating the screw body 13. Further, by tilting the height adjusting device 11 forward or backward, the vegetable transport section 4 can be lowered and stored stably to the lowest lowered position, and slightly raised from the lowest lowered position when traveling on the road or the like. Thus, the lower end of the transport device 40 can be prevented from coming into contact with an obstacle, and the scraping portion 3 can be prevented from obstructing the front view.

  During the work, the conveying device 40 is raised to the highest position, and then the height adjusting device 11 is raised by the operation of the operation lever, and the screw body 13 is rotated to match the height of the collar. And the height of the front-end | tip of the conveying apparatus 40 below the raking part 3 can be made to correspond substantially to the heel height by moving the conveying apparatus 40 down. During this work, you can pick up the onion without going into the ground. However, the height adjusting device 11 can also be constituted by a cylinder instead of the boss body 12 and the screw body 13, and by operating a switch or the like, the cylinder can be expanded or contracted by hydraulic pressure or a motor or the like to set the hit height to the operating portion. It can also be configured to be adjustable at 90. The height adjusting device 11 can also be provided on the transport device 40 side.

  Next, the divider 210 will be described with reference to FIGS. The divider 210 includes a support member 211 that is fixed to the vegetable conveyance unit, an upper member 212, and a lower member 213. The support member 211 is fixed to the front end of the drive case 49 of the conveying device 40 with a bolt. The support member 211 has a bolt hole formed by a long hole in the vertical direction, and the drive case 49 is loosened by loosening the bolt. The height can be adjusted by moving it up and down and fixing it. The upper member 212 is connected and fixed to the support member 211 by welding or the like. The lower member 213 is fixed to the upper member 212 with bolts, but the lower member 213 has bolt holes that are elongated in the vertical direction, and the bolts are loosened so that the support member 211 can be moved in the vertical direction. The height can be adjusted by moving and fixing. Therefore, when the height of the eaves is different between the left and right, or when the left and right central parts are high and the left and right sides are low, the lower members 213 on both sides can be lowered so that they can be grounded. If it is low, the support member 211 can be further lowered and grounded. In this way, it is possible to reliably pick up the onions on both the left and right sides toward the center.

  6 and 7 are diagrams comparing the divider according to the prior art and the divider 210 according to the present example. The right shows a divider according to the prior art, and the left shows a divider 210 according to this example. When the height of the ridge is high, as shown in FIG. 6, the angle of the conveying device 40 with respect to the ground is small, and in the conventional divider, a gap is formed at both ends in the left and right direction of the ridge. In 210, it is possible to fill a gap with the ground by lowering the position of the support member 211. In addition, if the gap with the ground is not filled only by lowering the position of the support member 211, the gap can be filled by lowering the position of the lower member 213. On the other hand, when the height of the kite is low, as shown in FIG. 7, the angle of the conveying device 40 with respect to the ground becomes large, and in the conventional divider, the both sides of the kite are sinking into the soil, By raising the position of the support member 211, it is possible to ground without sinking into the soil. Further, even when the ridge collapses due to wind and rain and soil accumulates in the ridge, the position of the support member 211 can be adjusted. With this configuration, the onion can be picked up without missing in the left-right direction of the vehicle body.

  Further, at the rear portion of the drive case 49 of the transport device 40, there is provided a rotation support portion 10 for the support arms 31 and 31 that support the scraping device 30, and at the rotation support portion 10, the scraping device. The rear end portions of the 30 support arms 31 are pivotally supported. The scraping device 30 is moved in the vertical direction by rotating the support arm 31 with the rotation support portion 10 as a fulcrum by a hydraulic cylinder 32 pivotally connected to a side portion of the transport device 40. It has become. With the above configuration, the ground height of the scraping device 30 can be individually set by operating the hydraulic cylinder 32.

  Further, instead of using the hydraulic cylinder 32, an elastic member may be used to support the height adjustment and elastic biasing. That is, as shown in FIGS. 18 and 21, support rods 55 and 55 are provided on the sides of the front and rear middle portions of the left and right drive cases 49. Further, a support rod 56 is provided horizontally on the left and right support arms 31. Stays 55a and 56a are projected from the support rods 55 and 56, and pivot pins 57 and 58 are pivotally supported on the stays 55a and 56a, respectively, and the pivot pins 57 and 58 are perpendicular to the axis. The screw rod 59 is passed through and arranged in a substantially vertical direction. The lower end of the screw rod 59 is fixed to the pivot pin 57 with a nut 60, and springs 61 and 62 are externally fitted to the screw rods 59 on both sides of the pivot pin 58 as elastic members. Washers 63, 63, 64, and 64 are disposed, respectively. A nut 65 is screwed to the lower part of the lower washer 63, and a nut 66 is screwed to the upper side of the upper washer 64. 67 is a lock nut.

  With this configuration, the pivot pin 58 fixed to the support arm 31 is elastically biased in the vertical direction by the springs 61 and 62, and the scraping portion 3 abuts against the convex portion on the collar or other Even if it comes into contact with an obstacle or the like, the pivot pin 58 slides up and down, the shock is relieved by the urging force of the springs 61 and 62, and damage or the like can be avoided.

  Further, by turning the lower nut 65 or the upper nut 66, it is possible to adjust the height of the scraping portion 3 with respect to the conveying device 40, and it is possible to adjust the biasing force by turning one or both of them. It is possible to change. That is, by rotating the lower nut 65 so as to slide upward (clockwise), the pivot pin 58 also slides upward, and the angle between the drive case 49 and the support arm 31 is increased. The scraping part 3 can be raised by enlarging and widening the space between the two. When the nut 66 is rotated so as to slide downward (counterclockwise), the pivot pin 58 also slides downward, reducing the angle between the drive case 49 and the support arm 31 and The scraping portion 3 can be lowered by narrowing the interval.

  In addition, the transport device 40 is configured in an interdigital shape by horizontally arranging a plurality of rod-like bodies on the left and right endless chains and winding them around the front and rear drive sprockets and driven sprockets. Thus, the harvested product can be conveyed by being driven to rotate. That is, as shown in FIG. 15, an endless vegetable conveyance surface 46 formed by alternately arranging a plurality of first conveyance bars 44, 44... And second conveyance bars 45, 45. Is done. Both left and right ends of the transport rods 44 and 45 are attached to transport chains 43 and 43 constituted by endless bodies built in a drive case 49 (see FIG. 15), and the transport chains 43 and 43 are driven (not shown). By driving the apparatus, the transport rods 44 and 45 are moved from below to above.

  The first conveying rod 44 includes a shaft member 44a and a hollow collar 44b, and the shaft member 44a is inserted into a hollow portion of the collar 44b. The shaft member 44a is attached to the transport chains 43 and 43, and the collar 44b is rotatable with respect to the shaft member 44a. The shaft member 44a is attached to the transport chains 43 and 43, and the collar 44b is rotatable with respect to the shaft member 44a. As described above, since the collar 44b is rotatable with respect to the shaft member 44a, even if the picked up onion falls on the first conveying rod 44, the shock due to the fall is relieved by the rotation of the collar 44b. Can be transported without damaging the onion.

  However, when a heavy vegetable such as an onion is transported, the collar 44b may be deformed due to an impact or weight due to the drop of the onion, and may not be able to rotate with respect to the shaft member 44a. Therefore, the collar 44b is divided into two parts by cutting substantially at the center in the left-right direction. In this embodiment, only one central portion is cut, but a plurality of portions can be cut. That is, the collar 44b can be divided into two or more in the axial direction. Preferably, increasing the number of divisions reduces the resistance and facilitates rotation. As described above, the collar 44b is divided into a plurality of parts so that the shaft member 44a can be rotated even if one end of the collar 44b is deformed due to an impact or weight due to the fall of the onion.

  On the other hand, the second transport rod 45 has a shape with projections and depressions in the longitudinal direction in plan view (front view), and both ends attached to the transport chains 43 and 43 are convex portions 45a and 45a. Portions other than 45a and 45a are formed as recesses 45b that are recessed substantially perpendicularly to the onion transport surface. That is, the second transport rod 45 is formed by recessing a portion other than the connection portion with the transport chains 43 and 43 with respect to the transport surface. And in the 2nd conveyance stick | rod 45, the recessed part 45b occupies most parts of a longitudinal direction.

  Since the concave portion 45b of the second conveying rod 45 and the vertical positional relationship between the first conveying rods 44 and 44 before and after the concave portion 45b are lower than the first conveying rods 44 and 44, the concave portion 45b 45b and the first conveying rods 44 and 44 form a triangular mounting space 47 in a side view (side view from the longitudinal direction of the first conveying rod 44). Further, the width and depth of the mounting space 47 in the transport direction are determined by the arrangement interval of the first and second transport rods 44 and 45 and the depression of the recess 45b, and thus are harvested. The width and depth of the mounting space 47 in the transport direction can be changed by appropriately changing the arrangement interval and the depression according to the size of the onion.

  In addition, since the onion naturally fits in the mounting space 47, the onion can be transported in a stable state. Further, a plurality of onions can be placed and transported in the left-right direction for one placement space 47, and a large amount of onions can be transported. Moreover, since the movement of the onion in the left-right direction is restricted by the convex portions 45a and 45a, the onion can be prevented from coming into contact with the transport chains 43 and 43 and being damaged. Moreover, since a clearance gap is formed between each conveyance stick | rod, the earth and sand adhering to an onion can be efficiently screened off to the ground through this clearance gap.

  Moreover, the inclination of the vegetable conveyance surface 46 is located above the endless vegetable conveyance surface 46 in which the first conveyance rods 44, 44... And the second conveyance rods 45, 45. Two bar-shaped conveyance guides 48 are arranged so as to extend along the line. The conveyance guides 48 and 48 are configured such that their lower end portions are fixed to, for example, drive cases 49 and 49 and their upper end portions are arranged at the upper end portion of the vegetable conveyance surface 46. And these conveyance guides 48 and 48 are so close to the left-right center of the vegetable conveyance surface 46 that it goes to the upper end part from this lower end part so that substantially "eight" shape may be formed in planar view, respectively. It is bent.

  Due to the presence of the conveyance guides 48 and 48, the onion widely placed in the left-right direction in the lower part of the conveyance device 40 is guided by the conveyance guides 48 and 48 as it is conveyed upward, and the conveyance device 40. In the upper part of, it is collected on the left and right center side.

  In addition, according to the above, it is possible to prevent the onion from spreading to the left and right and coming into contact with the transport chains 43 and 43 and damaging the onion, and to focus the onion flow within the range of the left and right width of the transport device 40. And can be reliably collected in the container 80. In addition, the conveyance guides 48 and 48 are configured to be removable, and according to the type of vegetable, by appropriately replacing with another conveyance guide having a different shape, the optimum focusing width according to the type of vegetable to be harvested And can be reliably collected in the container 80 even if the type and size of the vegetables to be harvested change.

  Moreover, the conveyance guides 48 and 48 are configured to be substantially parallel to the vegetable conveyance surface 46, and have a simple structure. In the vicinity of the upper end portion of the transport device 40, the transport guides 48 and 48 are bent as much as possible to be substantially horizontal with the ground surface, so that the vertical clearance between the vegetable transport surface 46 and the transport guides 48 and 48 is reduced. Thus, it is possible to reliably guide the container 80 in the direction in which the container 80 is arranged without passing the onion through the gap.

  Further, in the middle of the conveyance of the conveyance device 40, a spraying device 120 is disposed that blows air to promote drying of the harvested material and removes adhered soil and the like. As shown in FIG. 21, the spray device 120 has an air pipe 121 installed in the middle of the front and rear of the left and right drive cases 49, and the horizontal portion of the air pipe 121 is disposed in the left-right direction above the vegetable transport surface 46. Is done. A discharge port is opened at an appropriate interval on the lower surface of the horizontal portion of the air pipe 121 so that air is discharged to the vegetable transfer surface 46 side. In this embodiment, the support rod 55 is constituted by a pipe and is also used as an air pipe. One end of the air pipe 121 is closed, and the other end is connected to a discharge port of a pneumatic feeding means such as a compressor or a blower (not shown) via a hose or the like. The suction port of the pneumatic feeding means is arranged in the vicinity of the engine, or the hose is arranged so as to pass through the vicinity of the engine so as to warm the air to be fed. By arranging the suction port of the pneumatic feeding means in the vicinity of the engine, hot air can be sucked in. By blowing this hot air on the vegetable transport surface 46, the vegetable that is transported on the soil and contains moisture. Is dried, prevents decay and improves shelf life, and also removes attached soil and the like, reducing the labor of sorting and cleaning. In particular, by arranging the suction port of the pneumatic feeding means at the discharge port of the cooling fan of the engine, the cooling efficiency of the engine can be enhanced and the drying of vegetables can be promoted.

  Then, the harvested product is conveyed rearward by the conveying device 40 and is put into the container 80 from the end through a drop chute 85 described later. However, during transportation, the leaves or roots of the harvest may get entangled with the transportation rods 45 and 46 and do not leave and fall to the front and lower and cannot be stored in the container 80. In particular, since small vegetables are light, their leaf portions are easily entangled, are not easily dropped, and are easy to wrap around from the rear end of the conveying device 40 to the front and lower sides.

  Therefore, as shown in FIG. 17, the drive shaft 50 is horizontally mounted between the support columns 8, 8 on the rotation support portion 9, and the drive sprockets 51, 51 are fixed on the left and right sides of the drive shaft 50. ing. On the other hand, a driven shaft (not shown) is horizontally mounted on the front end of the drive case 49, and the driven sprockets are fixed on both the left and right sides of the driven shaft, and the transfer chain 43 · is placed between the driven sprocket and the drive sprockets 51 · 51. 43 is wound.

  The tension roller 52 is disposed between the front driven sprocket and the rear drive sprocket 51 to tension the transport chain 43. The arrangement position of the tension roller 52 is the non-conveying surface side on the lower surface side opposite to the vegetable conveying surface 46, and is disposed in the vicinity of the drive sprocket 51. In other words, the tension roller 52 is disposed diagonally forward and downward of the drive sprocket 51, and is tensioned so that the rear lower portion of the transport chain 43 extends horizontally or forward and upward from the rear end. The front upper end of the drop chute 85 is flat so as to have the trapezoidal shape when viewed from the side, and the tension roller 52 is disposed between the front end of the drop chute 85 and the vegetable transport surface 46.

  By comprising in this way, the conveyance chain 43 will rotate in the direction which escapes from the fall direction of vegetables in the drive sprocket 51 lower part, and vegetables will fall easily. Since the angle α between the conveying chain 43 extending forward from the rear end and the line connecting the lower tangent line of the drive sprocket 51 and the driven sprocket can be made larger than before, in particular, small vegetables are more than conventional. Also escapes at an angle α, so that entanglement is less likely to occur. Further, the space A formed between the transport chain 43 and the drop chute 85 is widened by flattening the front upper end of the drop chute 85, and the distance B between the lower portion of the drive sprocket 51 and the drop chute 85 is increased. Since it can be taken sufficiently, the crop is not clogged between the conveying rod of the conveying device and the dropping chute 85.

  Further, as shown in FIGS. 2 to 4 and FIG. 23, a sorting mechanism 200 is provided at the rear end of the conveying device 40 and above the drop chute 85. The scissor sorting mechanism 200 projects a plurality of elastic steel rods such as piano wires, or a bar body made of synthetic resin or the like from the support 201 in a rearward and upward direction to form a comb, It extends rearward and obliquely upward from the upper rear surface (inner side). Both ends of the support 201 arranged in the left-right direction are detachably fixed to the body frame (or the transport frame of the transport device 40) at the upper end inside the rear surface of the drop chute 85. In this embodiment, piano wire is used as the rod-shaped body, but it is also possible to use an elastic thin steel rod or spring. Further, in this embodiment, the rod-like body is substantially parallel to the comb shape, but it may be a net shape or a lattice shape.

  By configuring in this way, the portion of the onion leaf (the cocoon) cut along with the ball part of the onion is also conveyed from the conveying device 40 to the rear of the vehicle body. It becomes caught on the body and stays, and it becomes possible to prevent the container 80 from entering the drop chute 85. Note that the ball part of the onion falls by pushing the left and right elastic rods or jumps on the rods and falls backward. Further, when a certain amount of the accumulated soot portion accumulates, it is pushed forward and downward by the transporting rod 44 of the transporting device 40 that is rotating upward, and is a partition disposed below the non-transporting surface of the transporting device 40. It falls on the board, slides down as it is, and is released onto the field scene.

  Further, as shown in FIGS. 1 and 16, in the scraping portion 3, the drive shaft 35 is horizontally mounted on the left and right support arms 31 and 31, and the rotating wheels 24 and 25 are fixed to both ends of the drive shaft 35. ing. A drive case 31a provided in parallel with the right support arm 31 is provided with a power transmission mechanism for the drive shaft 35, and the drive shaft 35 is rotated by receiving power from the power transmission mechanism. The left and right rotating wheels 24 and 25 are respectively provided with arms 24a and 25a projecting radially in four directions in a radial direction, and a support shaft 26 is mounted between the distal ends of the left and right arms 24a and 25a. ing. A mounting portion 26a (see FIG. 16) having a width in the axial direction protrudes from the support shaft 26, and a scraper 34 is fixed to the mounting portion 26a. The scraper 34 has a rectangular shape with the left-right direction as a longitudinal direction, and is provided with vertical cuts (see FIG. 1) at a plurality of positions in the left-right direction as appropriate.

  A rotating wheel 27 that is eccentric with the rotating wheel 25 is mounted on the outer side of the right rotating wheel 25. The rotating wheel 27 is provided with arms 27a, 27a,. One end of the interlocking arm 28 is pivotally supported on the rotating shaft 27b provided at the tip of the arm 27a of the rotating wheel 27, and the other end of the interlocking arm 28 is fixed to the support shaft 26. .

  With the above configuration, each of the scissors 34 attached to each support shaft 26 is always rotated downward while maintaining a state in which a vertical surface is formed. The scraper 34 is formed of an elastic member such as resin (for example, rubber or vinyl) so that the onion is not damaged when the onion is scraped. In addition, the scraper 34 is formed thick, and it is easy to scrape a plurality of onions simultaneously with a single scraper 34. Moreover, it can also comprise so that it may not be easily bent by the reaction force received from the onion side by providing a separate reinforcement board in this scraping body 34. FIG.

  Further, as shown in FIG. 4, the support arm 31 of the scraping device 30 is provided with a front / rear position adjustment mechanism 33, and the front / rear position adjustment mechanism 33 can adjust the front / rear position of the scraping device 30. It has become.

  In addition, as shown in FIG. 2, a container transport table 71 is provided at a rear obliquely lower side of the upper end of the transport device 40. A plurality of rollers 71a and 71a arranged in the front-rear direction are rotatably arranged on the container transport table 71, and a transport surface on which the container 80 is transported in the left-right direction with respect to the machine body traveling direction is formed. As shown in FIG. 3, the container transport table 71 is disposed in the left-right direction above the crawler traveling devices 2 and 2, and as shown in FIG. 17, the front end is pivotally supported by the rear part of the machine body frame 5 so as to move upward. It can be rotated and stored. An operation unit 90 is disposed on the upper left side of the container transport table 71. A container table 75 on which an empty container 80 is placed is arranged on the right side of the container transport table 71. The vegetable harvesting machine 1 is for preventing the container 80 placed on the container stand 75 from falling to the side of the machine body and preventing it from falling over and to prevent the container 80 from slipping forward and falling down. A forward overturn prevention rod 304 is provided.

  Next, the fall prevention member of the container 80 will be described.

  Normally, the empty container 80 is formed by superposing the openings of one container 80 and the openings of the other container 80 into four rows in the vertical direction and four rows in the front-rear direction as shown in FIGS. 80 is placed on the container base 75. Furthermore, another container 80 is accommodated inside one container 80 and another container 80. Here, the lowest level of the container 80 is the first level, the highest level is the fourth level, the foremost column is the first column, and the last column is the fourth column. Since different containers 80 are stored in the first and second container 80 and in the third and fourth container 80, the first and second container The container 80 is not shifted and falls between 80 and between the third and fourth level containers 80. Therefore, the side fall prevention rod 300 and the forward fall prevention rod 304 are disposed at positions where they contact the second-stage and third-stage containers 80 to prevent the containers 80 from slipping and falling.

  The side toppling prevention rod 300 is for preventing the container 80 placed on the container stand 75 from being shifted to the body side and falling down. As shown in FIG. 9, the side overturn prevention rod 300 is formed by bending a front vertical portion of a pipe formed in a substantially gate shape in a side view obliquely rearward and downward in the middle, and further, the rear vertical portion and the front vertical The portions are reinforced by being connected by a connecting rod 301 disposed substantially horizontally. The side-to-side fall prevention rod 300 has a length in the front-rear direction substantially equal to the length in the front-rear direction of the four rows of the containers 80, and the height in the vertical direction is located in the middle of the container 80 at the third stage from the container stand 75. Is configured to do. The rear end of the side overturn prevention rod 300 is fixed to the column 8 on the side of the body frame 5 by the first mounting member 302, and the front end of the side overturn prevention rod 300 is attached to the body frame 5 by the second attachment member 303. It is fixed to the fuselage with bolts.

  In such a configuration, the container base 75 is inclined so that the outer (right side) end is raised and protrudes outward, so that the container 80 placed on the container base 75 has an inner side. Although it tries to fall to the side (left side), the side fall prevention rod 300 prevents the container 80 from falling and falling between the second stage and the third stage container 80 in the vertical direction. In the front-rear direction, by pressing the containers 80 from the first row to the fourth row, it is possible to prevent the container 80 placed on the container stand 75 from being shifted to the body side and falling down, The harvesting operation is temporarily stopped, and the fallen container does not damage the aircraft due to contact with the aircraft.

  The forward toppling prevention rod 304 is for preventing the container 80 placed on the container stand 75 from slipping forward and falling down due to start / stop or vibration. As shown in FIG. 8, in the forward fall prevention rod 304, the pipe is bent at approximately 90 degrees in the middle portion to form a vertical portion 304a and a lateral portion 304b, and the lateral portion 304b is obliquely upward in the middle portion. A diagonal portion 304c is formed by being bent into a letter-like shape. The forward toppling prevention rod 304 has a length in the left-right direction that is longer than half of the length in the left-right direction of the container 80, and a height in the vertical direction is positioned in the middle of the container 80 at the third stage from the container stand 75. It is configured. The forward toppling prevention rod 304 is attached via a first plate 306, a second plate 307, etc. with a midway portion (near the bent portion of the vertical portion 304a and the horizontal portion 304b) sandwiching the upper and lower sides at the front end of the operation rod 305. ing.

  The operating rod 305 is configured in a substantially L shape in a side view, and a portion bent downward from the rear end is used as a lever 310. The rear portion of the horizontal portion of the operation rod 305 is inserted into a through hole opened in the first mounting member 302 fixed to the vertical portion of the rear fall prevention rod 300 so as to be rotatable and slidable. Is inserted into a through hole of a third attachment member 308 attached to the middle part of the connecting rod 301 so as to be rotatable and slidable. The through hole has a hole diameter slightly larger than the outer diameter of the operation rod 305 and is provided in a substantially horizontal state. Therefore, the operation rod 305 is slid in the front-rear direction and rotated in the left-right direction. Can do. At the front end of the operating rod 305, a first plate 306 on the upper side and a second plate 307 on the lower side are fixed in parallel in the vertical direction, and are fixed to the operating rod 305 with bolts or the like. Further, a third plate 309 having a substantially L-shape in side view is fixed on the upper surface of the first plate 306, and a forward fall prevention rod 304 is attached to the rear surface of the third plate 309 in the vertical direction so as to fall forward. The prevention rod 304 and the operation rod 305 are connected and fixed via the first plate 306, the second plate 307, and the third plate 309. Further, a fourth plate 319 having a substantially trapezoidal shape when viewed from the front is fixed to the front ends of the first plate 306 and the second plate 307 substantially vertically, and the front end surface of the fourth plate 319 is a front side overturn prevention rod 300. It is in contact with the rear surface of the rear and serves as a stopper.

  The front overturn prevention rod 304 is rotatably inserted into the through holes of the first plate 306, the second plate 307, and the third plate 309 so that when the front overturn prevention rod 304 is not used, it can be rotated backward and stored. I have to. As shown in FIG. 24, in the forward overturn prevention rod 304, the forward rotation of the forward overturn prevention rod 304 is restricted by the lateral portion 304 b coming into contact with the vertical portion of the third plate 309. Then, the upper part of the vertical portion 304a of the front toppling prevention hook 304 can be brought into contact with the connecting rod 301, and the lower end can be brought into contact with the body frame 5, so that the rotation of the front toppling prevention hook 304 toward the inside of the body is restricted. Has been. Further, the front overturn prevention bar 304 holds a state where the detent mechanism prevents the container 80 from slipping forward and falls down, and a state where the container 80 is rotated and stored rearward, and is operated with a certain force or more. It is configured to be rotated. For this reason, the forward fall prevention rod 304 is not rotated by starting / stopping, vibration, or the like. As shown in FIG. 25, the stay 323 is fixed above the first plate 306 and above the vertical portion 304a to prevent the container 80 from slipping forward and falling down. A first pin hole is opened in the pin hole and the first plate 306. In addition, a second pin hole is opened on the upper surface of the first plate 306 in a state of being rotated and stored rearward. In a state where the container 80 is prevented from slipping forward and falling down, the pin hole and the first pin hole are aligned, and the pin 324 is inserted and fixed. Then, in a state where the pin 324 is pulled out and rotated backward and stored, the pin hole and the second pin hole can be aligned, and the pin 324 can be inserted and fixed.

  In such a configuration, at the time of a harvesting operation or the like, the second and third steps 3 and 3 are made by making the lateral portion 304b and the oblique portion 304c of the forward overturn prevention basket 304 substantially parallel to the left-right direction of the container 80. It is possible to prevent the containers 80 from slipping and falling forward between the containers 80 at the stage, and the harvesting operation is not temporarily stopped. Further, by rotating the vertical portion 304a rearward and folding it in the front-rear direction, the container base 75 is prevented from being rotated upward and folded and stored during storage. There is nothing. In addition, the front toppling prevention rod 304 has a length in the left-right direction that is longer than half of the length in the left-right direction of the container 80, and the center of gravity of the container 80 is located within the range of the length in the left-right direction of the front toppling prevention rod 304. Therefore, the container 80 is rotated around the place where the container 80 is in contact with the forward fall prevention rod 304 and does not fall down. Further, since the height in the vertical direction is located in the middle of the container 80 at the third stage from the container stand 75, the second stage and the third stage container 80 are not allowed to fall down. Can be prevented.

  In addition, a lever 310 is formed at the rear end of the operation rod 305. An operator or the like grasps the lever 310 and operates the operation rod 305 to move the forward overturn prevention rod 304 in the front-rear direction within a certain range. Or can be rotated in the left-right direction.

  In such a configuration, as shown in FIGS. 8 and 10, when the lever 310 is rotated clockwise as viewed from the front, the forward fall prevention hook 304 is also rotated in conjunction with the forward fall prevention hook 304. Is located in the middle of the fourth-stage container 80, and the lower end of the forward-fall prevention jar 304 is located in the middle of the first-stage container 80. The container 80 up to the eyes is locked. Then, as shown in FIG. 9, by pulling the lever 310 backward, the containers 80 for the two front rows are moved backward 2 until the first plate 306 and the second plate 307 come into contact with the third mounting member 308. It can be moved to the position of the container 80 for the row. Conventionally, when workers or the like use the fourth row and third row containers 80 in order from the rear, it has been necessary to temporarily stop the harvesting operation and carry the second row and first row containers 80 to the rear. By using the operation rod 305, the forward fall prevention rod 304 can be operated without temporarily stopping the harvesting operation, and the front container 80 can be easily moved rearward. The inner side of the bottom surface of the container table 75 is constituted by a pipe, and since the ground contact area between the container 80 and the container table 75 is small, the container 80 can move smoothly on the container table 75.

  As shown in FIGS. 11 and 12, a plate 320 is fixed to the base portion of the lever 310, and a pin 321 projects forward from a vertical surface of the plate 320. In addition, a pin hole is opened in the first mounting member 302 fixed on the rear surface of the rear side overturn prevention rod 300 so that the pin 321 can be inserted. On the other hand, a torsion spring 322 is fitted on the operating rod 305 in front of the third mounting member 308, one end of the torsion spring 322 is fixed to the operating rod 305, and the other ends are the first plate 306 and the second plate 307. In this example, it is fixed to the first plate 306 shown in FIG. 24 (FIG. 25), and the operating rod 305 is slid forward. And is urged to rotate in the clockwise direction in the rear view. With this configuration, an operator or the like grasps the lever 310, pulls the operating rod 305 rearward against the urging force of the torsion spring 322, removes the pin 321 from the pin hole, and pulls the lever 310 counterclockwise in a rear view. The container 80 can be pulled backward by rotating in the direction and pulling backward. Then, when the lever 310 is released, the operation rod 305 and the forward fall prevention rod 304 are automatically returned to the original positions in the front. For this reason, the operation | movement which returns the front fall prevention rod 304 pulled back to the front is also unnecessary.

  In addition, the shape of the side fall prevention rod 300 and the forward fall prevention rod 304 is not limited, and may be any shape that can prevent the container 80 from falling and falling. In addition, the forward fall prevention rod 304 is configured to rotate the operation rod 305 to lock the containers 80 from the first stage to the fourth stage. By bending the portion 304a, the container 80 is locked to the first-stage or second-stage container 80, and the containers 80 from the first stage to the fourth stage without rotating the operation rod 305 are operated. May be configured to be locked.

  As shown in FIG. 3, the ground height of the transport surface of the container transport table 71 is inclined in the left-right direction so that the container table 75 side is high and the operation unit 90 side is low. The container transfer table 71 is divided into a transfer table 71L and a transfer table 71R on the left and right, and the transfer table 71L on the side close to the left operation unit 90 uses the container 80 filled with the harvest as a field scene. The right conveyance table 71R is a table for the container 80 to be put in via the drop chute 85. In addition, it arrange | positions so that the fall chute | shoot 85 may cover above this left conveyance stand 71L, and it is preventing the harvest from entering directly. Thus, a locking member 311 to be described later is provided on the left end of the right transfer table 71R. When the empty container 80 on the container table 75 is moved onto the right transfer table 71R, the lock member 311 is stopped. The harvested product conveyed from the conveying device 40 in this state is accommodated in the container 80 via the drop chute 85. Then, when the container 80 on the right transport table 71R is filled with the harvested product, the container 80 is pulled to the operation unit 90 side by hand, and the locking member 311 is rotated while rolling on the right transport table 71R, so that the left transport is performed. The container 80 is moved down onto the field by moving it onto the platform 71L and rotating the left conveyance platform 71L rearward and downward.

  That is, as shown in FIG. 17, the left conveyance table 71L is divided into front and rear parts to form a front table 71b and a rear table 71c, and the length obtained by adding the front table 71b and rear table 71c in the front and rear direction is the front and rear length of the container 80. As substantially the same, the longitudinal length of the rear base 71c is configured to be slightly longer than the longitudinal length of the front base 71b, and the front portion of the front base 71b is pivotally supported by the body frame 5 so that it can rotate upward from a substantially horizontal state. It can be stored during work. The rear part of the front base 71b and the front part of the rear base 71c are connected by a fulcrum shaft 72 arranged in the left-right direction, the rear base 71c is supported so as to be able to rotate downward, and a spring 73 is interposed between the front base 71b and the rear base 71c. The rear base 71c is biased so as to rotate upward by the spring 73, and the upper surfaces of the front base 71b and the rear base 71c are normally in a straight and substantially horizontal state. Note that a spring force adjusting member may be configured and arranged with a bolt, a nut, or the like at a locking portion at one end of the spring 73. In such a configuration, when the container 80 on the right transport table 71R filled with the harvest is moved onto the left transport table 71L, the center of gravity of the container 80 storing the harvest is positioned behind the fulcrum shaft 72. Therefore, the rear portion of the rear base 71c is rotated downward by the weight of the container 80 and the harvested product, and the container 80 can also be tilted rearward to slide on the rear base 71c and be automatically lowered onto the field scene. When the container 80 disappears on the rear base 71c, the rear base 71c is turned up and returned to its original position by the biasing force of the spring 73. It is assumed that the center of gravity is in a state where the harvest is uniformly stored in the container 80 and is located at the approximate center of the front, rear, left, right, top and bottom.

  It is also possible to drop the container full of harvested products onto the field after confirming that the container has been placed on the left carrier 71L. That is, the length of the left carriage 71L is divided into the front and rear, and the length of the front carriage 71b and the rear carriage 71c added in the front-rear direction is substantially the same as the longitudinal length of the right carriage 71R. It is configured to be slightly shorter than the longitudinal length of 71b, and a spring 73 is interposed between them in the same manner as described above. In such a configuration, when the container 80 filled with the harvest is moved from the right transport table 71R to the left transport table 71L, the center of gravity of the container 80 storing the harvest is positioned in front of the fulcrum shaft 72. Therefore, the container 80 is placed on the front base 71b and temporarily held, and the rear base 71c does not turn down when the container moves in the lateral direction, and the container 80 does not turn over. By pushing down the rear side by hand, the container 80 is inclined rearward, and the center of gravity moves rearward from the fulcrum shaft 72 so that it slides down on the rear base 71c by its own weight, and can be lowered to the field scene. Further, the left conveyance table 71L may be configured to rotate downward by an actuator 79 such as a cylinder, as an integral configuration that is not divided into front and rear. That is, an actuator such as a cylinder may be interposed between the left carriage 71L and the body frame 5, and the left carriage 71L may be lowered or raised by an operation of a switch, a lever, or the like. In this case, an elevating switch is disposed in the operation unit 90 and is raised and lowered by an operator's switch operation. Alternatively, a sensor 21 comprising a contact or light sensor or a weight sensor for detecting the presence or absence of a container is arranged on the left transport table 71L, and when the container 80 is positioned on the left transport table 71L, the sensor 21 is lowered, and from the left transport table 71L. It can also be configured to rise when it runs out. In this case, as shown in FIG. 3, the container detection sensor 21 is arranged at the rear left end of the left conveyance table 71L, the actuator 79 is arranged on the left side of the left conveyance table 71L, and the container detection sensor 21 and the actuator 79 are the controller. 23.

  Next, an example in which the locking member 311 prevents the container 80 from moving to the left conveyance table 71L will be described.

  The locking member 311 is for temporarily stopping the container 80 from moving from the right conveyance table 71R to the left conveyance table 71L due to the rolling of the roller 71a at the left end of the right conveyance table 71R. As shown in FIGS. 13 and 14, the locking member 311 is a pipe member having a substantially U shape in a plan view and a substantially U shape in a side view, and both ends of the locking member 311 are rods 313 arranged in the vertical direction. It is fixed to the upper part and the middle part. The lower part of the rod 313 is rotatably supported inside a hollow cylindrical member 312 provided at the rear part of the body frame 5, and the container 80 moves in the direction from the right conveyance table 71R to the left conveyance table 71L. They are arranged so as to be substantially orthogonal. A plate 314 having a substantially triangular shape in plan view is fixed to the lower surface of the rod 313 by bolts 315. The plate 314 is provided with a first protrusion 316 that protrudes downward, and a spring 318 is interposed between the first protrusion 316 and the second protrusion 317 of the body frame 5.

  In such a configuration, when the empty container 80 is slid leftward from the container table 75 and moved onto the right conveyance table 71R, the left side surface of the container 80 comes into contact with the locking member 311 and the left conveyance table 71L. It is temporarily stopped so that it does not move to. Then, when the harvest is put into the container 80 placed on the right conveyance table 71R and the container 80 becomes full, the operator or the like draws the container 80 toward the control unit 90, or the control unit from the container table 75 side. When pushed to the 90 side, the locking member 311 can be rotated leftward against the urging force of the spring 318 and placed on the left conveyance table 71L. Since the locking member 311 automatically returns to the original state by the urging force of the spring 318, an operation of returning the locking member 311 is not necessary.

  The shapes of the rod 313 and the locking member 311 are not limited, and any shape that can lock the container 80 may be used. For example, the locking member 311 may be a plate-like member, or the rod 313 may be provided with the locking member 311 in a cantilever manner. Moreover, the rod 313 and the locking member 311 can also be comprised with the same member. Further, the height of the rod 313 and the locking member 311 and the horizontal length of the locking member 311 can be adjusted according to the size of the container 80 and the like.

  It is also possible to automatically place the container 80 placed on the right transport table 71R on the left transport table 71L. In other words, the weight sensor 22 is arranged on the right conveyance table 71R to detect the weight of the container 80. On the other hand, the locking member 311 is a member that temporarily stops the container 80 from moving to the left conveyance table 71L due to the rolling of the roller 71a, and is configured as a convex member that can be easily overcome. The locking member 311 is configured to be movable up and down, and the locking member 311 is configured to be lifted and lowered by an actuator 78 such as a cylinder or a motor. Then, the actuator 78 and the weight sensor 22 are connected to the controller 23.

  In such a configuration, a harvested product is put into the container 80 placed on the right conveyance table 71R, the weight of the container 80 is detected by the weight sensor 22, and the value is input to the controller 23. When the detection value of the weight sensor 22 reaches the set value, that is, when the weight of the container 80 reaches a set weight that is substantially full of the harvested product, the actuator 78 is operated to lower the locking member 311. Then, the container 80 placed on the right conveyance table 71R is released from the engagement of the engagement member 311. By the inclination of the container conveyance table 71, the roller rolls by its own weight and automatically moves onto the left conveyance table 71L. Move. Then, when the container 80 is not present on the right conveyance table 71R, the value of the weight sensor 22 becomes equal to or less than the set value, and the locking member 311 is raised to the original position, and the next empty container 80 can be locked. As described above, the container 80 on the left carriage 71L is lowered onto the field with the left carriage 71L tilted rearward and downward. However, if there is no empty container 80 on the container stand 75, the harvested product cannot be accommodated when the container 80 is moved onto the left transfer stand 71L. Therefore, an empty container is placed on the container stand 75 on the right side of the right transfer stand 71R. A detection sensor 29 is arranged, and the empty container detection sensor 29 is connected to the controller 23. The controller 23 is connected to an operation actuator 81 for the main clutch or an actuator for stopping the engine. Thus, when the weight sensor 22 detects that the weight of the container 80 is the set weight, the empty container detection sensor 29 detects whether or not the empty container 80 is on the container table 75, and if so, the actuator 78 is activated. Then, the locking member 311 is lowered to move the container 80 to the left conveyance table 71L, and at the same time, the empty container 80 is also moved from the container table 75 to the right conveyance table 71R. When the empty container 80 is not on the container stand 75, the actuator 81 is operated to stop traveling and transporting or stop the engine to replenish the empty container.

  An empty container 80 is placed on the container stand 75 to stand by, and the container 80 is supplied from the container stand 75 to the container transport stand 71. The container base 75 and the container transport base 71 form a series of container transport units 7.

The distance from the inner end to the right end of the left carrier 71L (the distance to the container 80) A is shorter (A> B). With this configuration, even when the crawler 2 is positioned between the ridges, the work is performed while traveling, turning at the end of the field, and when the next strip is harvested, the container stand 75 protrudes to the previous strip side. The tip of the container table 75 does not come into contact with the container 80 lowered in the previous work, and the container 80, the container table 75, etc. are not damaged.

  As shown in FIG. 2, the operation unit 90 includes a clutch lever 91, side clutch levers 92 and 93, an accelerator lever 94, an engine switch 95, and the like. The shift guide of the clutch lever 91 is formed in a U shape having a low speed side (use during operation) and a high speed side (use during movement). When the clutch lever 91 is put on the low speed side (used during work), a clutch for inputting driving to the working unit (conveying device 40, scraping device 30) and driving to the traveling unit (crawler traveling device 2) are input. Both for the clutch to be connected. Thereby, it will be in the state which can be worked. Further, when the accelerator lever 94 is set to the neutral position and the clutch lever 91 is moved to the low speed side, the clutch for inputting the drive is connected to the working portion (the transport device 40 and the scraping device 30) and stopped. In the state, the working unit can be driven.

  On the other hand, when the clutch lever 91 is put on the high speed side (used during movement), the clutch for inputting the drive to the working unit (conveying device 40, scraping device 30) is disconnected, and the traveling unit (crawler traveling device 2) is disconnected. A clutch for inputting drive is connected. Thereby, it will be in the state which can drive | work. The engine switch 95 is configured, for example, as a push button, and when the switch is operated, the engine is stopped and the driving of the working unit / traveling unit is stopped. With this configuration, when it is necessary to replace the container 80 or the like during work, the drive of the working unit / traveling unit can be quickly stopped by one operation of the engine switch 95. Is improved. In addition, since the drive system of the working unit (conveying device 40 and scraping device 30) and the driving system of the traveling unit (crawler traveling device 2) are independent from each other, for example, the transport device 40 and the scraping device It is possible to make the driving speed of the device 30 constant and reduce only the traveling speed by operating the accelerator lever 94 so that the onion is surely scraped.

  In the configuration shown in FIG. 4, the left and right arrangements are reversed, that is, the container base 75 is arranged on the left side (lower side in the drawing of FIG. 4) with respect to the aircraft traveling direction, and the operation unit 90 may be arranged on the right side.
