  With the above-described configuration, by providing a control member that can perform a plurality of operations by one, such as the speed change operation lever 13 and the lifting operation lever 14, the operation of the airframe is facilitated, so that the operator's work can be reduced. .

Next, the configuration of the harvesting unit C will be described.
As shown in FIGS. 1 to 3, left and right driven pulleys 16 and 16 are rotatably mounted on the front side of the left and right pull-out frames 15 and 15, and left and right drive pulleys 17 and 17 are mounted on the rear side of the body. Between the pulleys 16, 16 and the left and right drive pulleys 17, 17, the left and right nipping and conveying belts 18, 18 for pulling out the carrots and conveying them to the rear part of the machine body are wound. 18 is tensioned so that the side surfaces of the left and right nipping and conveying belts 18 and 18 are pressed against each other to form a carrot pulling and conveying path R. A rotating frame 20 that can be rotated in the vertical direction is attached to the upper side of the body frame 1 with the left and right horizontal shaft 21 as a rotation fulcrum, and is attached to the left and right drive pulleys 17 and 17 at the rear end of the rotating frame 20. A transmission case 22 for transmitting the driving force is attached so as to be rotatable up and down around the rotation fulcrum X. Further, the body frame 1 and the rotating frame 20 are connected by an elevating cylinder 23, and the elevating cylinder 23 is operably attached by a control part B to constitute a pulling and conveying device 24.

  Further, a vertical elevating device 25 that causes a carrot foliage portion to be raised by a vertical lug 25a in front of the drawing and conveying device 24, and a horizontal elevating device 26 that raises the foliage portion raised by the vertical elevating device 25 by a horizontal lug 26a. When the handle 29 is turned, a rotatable gauge ring 31 is provided at the lower end portion of the telescopic rod 30 that vertically expands and contracts to prevent the pulling and conveying device 24 from descending too much.

  Further, left and right solitary frames 32, 32 are attached from substantially lower positions in the longitudinal direction of the fuselage from the lower front side of the fuselage frames 15, 15, and left and right vibrations are attached to the front ends of the sora frames 32, 32. The front end portions of the arms 33 and 33 are attached. A vibration shaft 34 that rotates in response to the driving force of the engine 7 is extended toward the front side of the machine body frame 1 toward the side where the pulling and conveying device 24 is provided. A transmission device G is configured by attaching a vibrating rod 35 having a V-shape in a side view for vibrating the vibrating arms 33, 33 between the side ends. The vibration arm 33 inside the machine body is rotatably attached to the lower end side of the vibration rod 35.

  Then, left and right soilers 37, 37 that cut through the soil around the carrots are attached to the connecting portion between the solitary frames 32, 32 and the vibrating arms 33, 33 toward the front side of the machine body. The vibration device 36 is configured by attaching the base portions of the left and right earth retaining stays 38 and 38 inside the portion where the base portions 37 and 37 are attached.

  In addition, when the soiler 37 is configured by a blade portion 37b that enters the soil and unravels the soil around the carrot, and an arcuate mounting portion 37a that extends rearward and upward from the blade portion 37b, the soiler 37 is made of the soil. Since the resistance applied when entering the inside is dispersed and reduced, the aircraft progresses smoothly and the work efficiency improves, and it is matched to the difference in field conditions due to soil quality and weather, and the type and growth state of carrots. Thus, the vertical position adjustment of the soiler 37 can be easily performed, so that carrots can be easily digged and the work efficiency is improved.

  Further, since the rotation speed of the vibration shaft 34 that vibrates the vibration device 36 is not linked to the speed change operation of the transmission case 8, the vibration width does not change even when the traveling speed is low. Since the left and right soilers 37 can be vibrated with the same width even during the work, the work efficiency is improved, and the soil around the carrots is cut out, so there is less leftover, so it is left behind after the harvesting work. The work of removing the carrots is omitted, and the labor of the worker is reduced.

  Moreover, earthing brushes 39, 39 using synthetic resin such as polypropylene and acrylic, or natural materials such as cocoons and sheep teeth are attached to the rear portions of the earthing stays 38, 38. If the hairs of the same length are used for the top and bottom of the earthing brushes 39 and 39, the upper and lower sides of the earthing brushes 39 and 39 are switched when the upper hair, which has many opportunities to come into contact with carrots, is worn. If it is made, since the hair which is not worn can be brought into contact with the carrot, the soil brushes 39 and 39 can be made to last for a long time.

  Further, the left and right intervals of the earthing brushes 39 and 39 are arranged so that the front side of the airframe is widest (width W1) and narrows toward the rear side of the airframe, and the right and left widths of the earthing brushes 39 and 39 are narrowest. The portion (width W2) is configured to face in the left and right outer direction.

  And the front end part of the left and right soilers 37, 37 crawls up and down the left and right lifting projections 40, 40 that crawl up the foliage hanging in the field, and the front part is located in front of the lateral lugs 26 a of the device 26. Arrange to do. Further, the left and right guide bars 41, 41 that guide the stems and leaves scooped up by the ridge protrusions 40, 40 to the front side of the ridge protrusions 40, 40 to the holding start end of the pulling and conveying device 24 are shown in a plan view. The guide bars 41 are attached so that the left and right spacing between the guide bars 41 decreases toward the rear side of the machine body.

  When the guide bars 41 and 41 are made of a cylindrical elastic material having a high degree of flexibility such as a piano wire and having a certain degree of hardness, the vibration width is increased and the effect of preventing the tangles from being entangled is improved.

  Further, left and right weed bodies 42, 42 that are wider than the above-mentioned ridge protrusions 40, 40 and cover the upper surfaces of the ridge protrusions 40, 40 in a tilted rearward posture are provided. In addition, the space part in which the said guide bars 41 and 41 protrude is formed in the upper part of the weed bodies 42 and 42. As shown in FIG.

  Further, a tail portion for cutting a carrot root (tail portion) being transported by the pulling / conveying device 24 on the machine body frame 1 below the pulling / conveying passage R and behind the earth brushes 39, 39. By attaching the cutting device 43, the harvesting section C is configured.

  With the above configuration, the vertical raising device 25 and the horizontal raising device 26 are provided on the front side of the machine body, thereby causing the ginseng stems and leaves lying in the field to be caused vertically by the vertical lugs 25a of the device 25, and the caused foliage is caused. The horizontal lug 26a of the horizontal pulling device 26 can be lifted and moved to the nipping and conveying start end of the pulling and conveying device 24. The remaining ginseng is reduced and the work efficiency is improved.

Further, if the harvesting section C is raised during turning, the lower end of the harvesting section C is less likely to come into contact with the field, so that the turning operation is performed smoothly and the work efficiency is improved.
Then, weed bodies 42, 42 are provided on the upper projections 40, 40 at the tip of the soilers 37, 37, and the stems and leaves that are laterally raised and failed to take over by the device 26 are scooped up by the weed bodies 42, and are guided through the guide bars 41, 41. By adopting the structure in which the foliage is guided to the clamping start end of the pulling / conveying device 24, the foliage is more securely held by the pulling / conveying device 24 and pulled out from the field. improves.

  Furthermore, by raising the foliage with the vertical pulling device 25, the horizontal pulling device 26 and the weeds 42, 42, the foliage that has hidden the carrots can be removed and the visibility of the carrots to be harvested can be improved. It makes it easier to align the carrot extraction position and reduces the amount of crop leftover, improving work efficiency. In addition, since the weed bodies 42 and 42 are wide enough to cover the periphery of the thin plate-like ridge protrusions 40 and 40, the surroundings of the carrot to be harvested are not obstructed.

  Then, by providing the gauge ring 31 at the lower end of the telescopic rod 30 that expands and contracts up and down when the handle 29 is turned, if the gauge ring 31 is brought into contact with the farm scene, the pulling and conveying device 24 will not be lowered any further. It is possible to prevent the lower end portion of the pulling / conveying device 24 from coming into contact with the field scene and being damaged due to an operation error or unexpected ground irregularities.

  Then, the body frame 9 and the pivot frame 20 that is pivotable in the vertical direction are connected by a lift cylinder 23 with the left and right horizontal shaft 21 as a pivot, and the lift cylinder 23 is operated by the lift control lever 14 of the control unit B. With this configuration, the vertical height of the entire harvesting section C can be adjusted by operating the lifting operation lever 14, so that the position of the pulling and conveying start end of the harvesting section C is adjusted in the vertical direction. At the same time, the position of the pulling conveyance start end portion can be adjusted in accordance with the appropriate pulling height of the carrots vegetated on the field, and the leftover of the carrot is prevented, so that the work efficiency is improved.

  The left and right earthing stays 38 and 38 having the earthing brushes 39 and 39 are attached to the left and right vibrating arms 33 and 33 that vibrate the left and right soilers 37 and 37, respectively. Since it vibrates in the vertical direction of the fuselage together with the arranged soira 37, 37, the soil adhering to the carrot can be scraped off in the vertical direction, and the carrot body also vibrates. However, soil that does not come into contact can also be removed by vibration, making it easier for the sorting operator to identify carrot scratches (breaks, breaks, bruises, decay, etc.) and shape abnormalities (such as bifurcation, excessive bending, or minimum). Therefore, the carrot sorting accuracy is improved.

  In addition, by attaching the bases of the earth retaining stays 38, 38 to the opposite side of the bases of the soilers 37, 37 of the vibrating arms 33, 33, the earth retaining stays 38, 38 are adjacent to the adjacent strips, particularly on the unexcavated side ( Since it is separated from the carrot on the side that has not yet been pulled out), it is possible to prevent the soil stays 38, 38 from coming into contact with the carrot on the unexcavated side, preventing the carrot from being damaged and improving the commercial value. In addition, since it is difficult for human hands to approach, safety is improved.

  Furthermore, since the earth-moving brushes 39 and 39 are vibrated by the vibration device 36, it is not necessary to provide a special vibration mechanism, the number of parts is reduced, cost reduction and resource conservation are achieved, and the airframe configuration is simplified. , Assembly and maintenance of the fuselage are facilitated.

  In addition, by arranging the gaps between the earth dropping brushes 39, 39 so that the front side of the machine body is widest and the rear side of the machine body is narrowed, when a crop having a larger upper diameter than the lower diameter passes like a carrot, Since it can pass without being caught between the left and right of the drop brushes 39, 39, the carrot harvesting operation is not interrupted, and the work efficiency is improved. Moreover, the soil adhering to the carrot can be surely dropped in the vertical direction, and it becomes easier for the sorting operator to discriminate the carrot's scratches and abnormal shapes, thereby improving the carrot sorting accuracy.

  In addition, since the rear sides of the earthing brushes 39 and 39 are formed narrowly, when a small-diameter carrot passes, they contact the earthing bars 38 and 38 at least near the narrowest rear end of the earthing brushes 39 and 39. Therefore, the soil adhering to the carrot can be surely dropped, and it becomes easier for the sorting operator to discriminate the carrot's scratches and abnormal shapes, thereby improving the carrot sorting accuracy.

  Since the soil brushes 39 and 39 are arranged on the front side of the machine body relative to the machine frame 1 and the tail cutting device 43, the soil adhering to the carrots falls on the vibrating soira 37 and 37 or on the field. Since the work of removing the soil adhering to the surface is omitted, the maintainability is improved and the labor of the operator is reduced. In particular, the soil is more easily dropped by not connecting the left and right of the earthing brushes 39, 39, and the angle adjustment of the earthing brushes 39, 39 can be performed separately on the left and right by not connecting the left and right. Since it can, it can respond to various working conditions.

  And since it contacts the tail cutting device 43 in a state in which the soil adhering to the carrot has been removed, it is prevented that the soil falling from the carrot is accumulated in the tail cutting device 43, improving the maintainability, Since the cutting blade (not shown) of the tail cutting device 43 is prevented from being damaged by the resistance in contact with the soil, the durability is improved.

Next, the foliage cutting part D will be described.

Further, if the extruded disk 49 has substantially the same diameter as the first cutting blade 46o or a slightly larger diameter than the first cutting blade 46o, the extruded disk 49 can easily come into contact with the ginseng shoulder, and the ginseng shoulder becomes the fuselage. It is possible to make the posture facing inward, and the remaining leaf processing conveyor 57 reliably processes the leaf and leaf portion remaining on the root portion, so that it is not necessary to remove this leaf and leaf portion in a subsequent process, and the work efficiency is improved.

  Since the average thickness of the first cutting blade 46o and the second cutting blade 46i is about 1 mm, the thickness of the spacer 48 is about 2 mm, so that the first cutting blade 46o and the second cutting blade 46i are formed on the extrusion disk 49. It becomes difficult to entrain. Body cutting (a method of cutting the upper part of the root, not the border between the stem and the root. Processed products such as vegetable juice are not so important in appearance, it is important that there is no foliage. When it is necessary to increase the thickness of the first cutting blade 46o and the second cutting blade 46i, such as a cutting method becomes possible, the thickness of the spacer 48 may be increased.

  Further, as shown in FIG. 11, when the extrusion disk 49 is configured to have a plurality of pointed extrusion protrusions 49a at equal intervals like the star wheel, the extrusion protrusions 49a intermittently contact the carrot. Since the carrots are pushed out one by one inward of the machine body, the direction of the carrot shoulder is surely directed toward the end of the conveyance direction (inner direction of the machine body) of the remaining leaf processing conveyor 57 provided with the remaining leaf processing roller 56. In addition, since the foliage remaining on the root can be reliably processed by the remaining leaf processing roller 56, there is no need to remove the foliage in a subsequent process, and the work efficiency is improved.

  In addition, since the foliage part being conveyed enters the space between the extruding projections 49a, the foliage part is prevented from escaping from the foliage cutting device 47, and the foliage part is reliably cut to bring the carrots inward of the fuselage. Since it can be pushed out, ginseng is not moved and discharged to the end part of the foliage transport devices 45i, 45o where the foliage part has not been cut, the work efficiency is improved, and it is necessary to collect the discharged ginseng from the field The work effort is reduced.

  Furthermore, as shown in FIG. 12, when the extrusion protrusions 49a are formed in an arc shape, the contact time is shorter than that of the above-described pointed extrusion protrusions 49a, so that the falling carrots can be more reliably pushed out one by one. The work efficiency is further improved, and the foliage part is more difficult to escape from the foliage cutting device 47, so that the work efficiency improvement effect and the labor reduction effect are marked.

  A regulation plate 50 is provided on the rear side of the foliage cutting device 47 to restrict the change in the falling posture of the carrots cut from the foliage part. The cushion plate 51 that receives the falling ginseng is disposed at least on the lower side in the conveying direction from the carrot falling position along the conveying direction of the remaining leaf processing conveyor 57.

  If the restriction plate 50 and the cushion plate 51 are made of a soft material such as rubber or vinyl chloride, the carrot can be prevented from being damaged by the impact of a collision, and the commercial value of the carrot can be improved.

  Further, a foliage shooter 52 that discharges the foliage cut by the foliage cutting device 47 from the terminal ends of the foliage transfer devices 45i and 45o on the inner and outer sides of the machine body to the field is provided to constitute the foliage cutting portion D.

  With the above configuration, the extrusion disk 49 mounted below the rotation axis f of the first cutting blade 46o outside the machine body is elastically deformed when it comes into contact with the crop before cutting the foliage, and the carrot after cutting the foliage is elastically restored. Since the carrot shoulders, which are extruded and left by cutting, can be directed in the direction perpendicular to the conveyance path of the foliage conveying devices 45i, 45o (inner direction), the remaining leaf processing conveyor 57 is provided. The remaining leaf processing roller 56 can surely remove the foliage part, and there is no need to remove the foliage part in a subsequent process, thereby improving the work efficiency. Since this extrusion disk 49 is provided on the outside of the machine body, it is not pushed out toward the outside of the machine body if it is a carrot that has been normally nipped and conveyed by the drawing / conveying device 24.

  In addition, by providing a regulating plate 50 for restricting the change in the fall posture of the carrot with the foliage cut off on the rear side of the foliage cutting device 47, the posture of the carrot can be prevented from changing during the fall. The leaf and leaf portion remaining on the shoulder portion can be reliably removed by the remaining leaf processing conveyor 57, and there is no need to remove the leaf and leaf portion in a subsequent process, thereby improving work efficiency.

  And by providing the cushion plate 51 which receives the carrot which has fallen below the foliage cutting device 47 and above the remaining leaf processing conveyor 57, it is possible to prevent the carrot from being damaged by the impact of the drop. Value is improved.

  In addition, the carrot pushed out to the extrusion disk 49 falls from the lower end (hereinafter referred to as the tail), but if it falls on the remaining leaf processing conveyor 57 that continues to move in a certain direction during the harvesting operation, the remaining leaf processing is performed. Due to the conveying force of the conveyor 57, the shoulder may face the opposite side of the conveying direction. However, since the cushion plate 51 is provided above the remaining leaf processing conveyor 57, the carrot is placed on the remaining leaf processing conveyor 57 after coming into contact with the cushion plate 51 and taking a posture along the conveying direction of the remaining leaf processing conveyor 57. Therefore, the foliage portion can be reliably removed by the remaining leaf processing conveyor 57, and there is no need to remove the foliage portion in a subsequent process, thereby improving the work efficiency.

  Furthermore, the defoliation shooter 52 that discharges the leaves discharged from the carrots by the foliage cutting device 47 (the cut foliage portion) to the field seems to discharge the foliage to the already dug side (the side where the carrots have been harvested). Is provided in a downwardly inclined position, the discharged stems and leaves fall on the carrots on the undigged side (the side where the carrots are not harvested), and the drainage leaves the left and right nipping and conveying belts 19 and 19 and the left and right driven Since it is possible to prevent the harvesting section C from being stopped by being entangled with the pulleys 17, 17, etc., it is possible to prevent the harvesting operation from being disturbed. Can be prevented.

Then, the pumping conveyance belt 61 is wound endlessly around the pumping conveyance driving roller 59 and the pumping conveyance driven roller 60 in front of the machine body and adjacent to the residual leaf processing conveyor 57 with respect to the residual leaf processing conveyor 57, A pumping conveyer 62 is formed which takes over the carrot from the remaining leaf processing conveyor 57 and the cradle 58 and pumps it to the left and right sides of the machine body.

The above-described remaining leaf processing conveyor 57 and the uplifting conveyor 62 provided in the upward inclined posture constitute the uplifting conveying section E.
With the above configuration, the remaining leaf processing roller 56 constituting the remaining leaf processing conveyor 57 transports the carrots to the pumping conveyor 62 while cutting off the remaining leaves of the carrots cut and cut by the stem and leaf cutting device 47. The value is improved and the work of manually cutting the remaining leaves after the harvesting work can be omitted, and the work efficiency is improved.

  Further, the remaining leaf processing belt 55 constituting the remaining leaf processing conveyor 57 is made of an elastic material such as rubber or urethane, so that the remaining leaf processing belt is removed even if the ginseng falls after the leaves are cut off by the foliage cutting device 47. Since 55 reduces the impact of the drop, the carrot is prevented from being damaged by the impact of the drop, and the quality of the carrot is improved.

  Then, by providing a grid-like pedestal 58 on the starting end side of the remaining leaf processing conveyor 57 and on the front side of the machine body in a descending inclined posture, the foliage part fell off on the front side of the machine body from the foliage cutting device 47 and dropped. The carrot can be received without being dropped outside the machine, and the received carrot can be moved toward the pumping conveyer 62, so that the work of collecting the carrot that has fallen outside the machine after the harvesting work is omitted. The labor of the operator is reduced, and the carrot that has fallen on the front side of the machine body relative to the foliage cutting device 47 can be returned to the transport path, so that the work efficiency is improved.

As a result, it is possible to prevent the carrot from being damaged by the impact of a drop and to improve the product value of the carrot.

  Further, when the shooter 69 is turned upward, it becomes a stopper that closes the terminal end side of the sorting and conveying conveyor 68. Therefore, when replacing a container full of carrots, the carrot can be moved without stopping the sorting and conveying conveyor 68. Since it is possible to prevent the carrot from falling from the end portion, it is necessary to prevent the carrot from being damaged by the impact of the drop and improve the quality of the carrot, and it is necessary to frequently turn the power of the sorting and conveying conveyor 68 on and off. The work efficiency is improved.

  Further, the carrot accumulates on the terminal side of the sorting and conveying conveyor 68 by stopping the sorting and conveying conveyor 68 by turning the shooter 69 upward to make it a stopper.
