  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. Then, a vibration shaft 34 that rotates in response to the driving force of the engine 7 is extended to the front side of the body frame 1 toward the side where the pulling / conveying device 24 is provided, and the vibration shaft 34 and the vibration arms 33 and 33 are disposed behind. 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 vibration arms 33, 33 at a substantially central position in the front-rear direction. The base of the left and right U-shaped earth dropping bars 38, 38 is attached in the side view of dropping the soil adhering to the carrots inside the place where the base is attached, and the action part on the end side of the earthing bars 38, 38 is attached. The vibration device 36 is configured in a substantially horizontal posture with respect to the field scene.

  It should be noted that the rotational speed of the vibration shaft 34 that vibrates the vibration device 36 is configured not to be interlocked with the speed change operation of the mission case 8, so that 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.

  Further, the earthing bars 38, 38 are made of a cylindrical elastic material which is rich in flexibility such as piano wire and has a certain degree of hardness, and the surface is a tube made of a soft material such as polyvinyl chloride, sponge or urethane. It covers with the cover 39 which comprises the shape.

If the covers 39, 39 are detachably attached from the earthing bars 38, 38, they can be replaced immediately when the covers 39, 39 deteriorate due to friction or the like.
Further, the distance between the left and right sides of the earthing bars 38 and 38 is formed to be widest on the front side of the body and narrower toward the rear side of the body, and the narrowest part of the left and right widths of the earthing bars 38 and 38 is formed on the left and right sides. Bend in the 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, as shown in FIG. 6 to FIG. 9, an arc shape in which a plurality of slits 43 s are formed in the digging frame 20 below the pulling conveyance path R and behind the earth dropping bars 38, 38. A guide cover 43 is attached.

  Then, a U-shaped rotary cutting blade 44 is provided inside the guide cover 43 in front view (or rear view) for cutting the root of the lower part of the carrot root being transported by the pulling and transporting device 24, and the rotational cutting is performed. A drive motor 45 that supplies a driving force to the inside of the rotation diameter of the blade 44 is attached via an output shaft 45a.

  The drive motor 45 rotates the rotary cutting blade 44 in the same direction as the carrot conveyance direction of the pulling and conveying device 24 in a plan view and clockwise (clockwise) in a side view. The drive motor 45 uses an electric motor that receives electric power from a battery (not shown) of the fuselage and is driven by an operation from the control unit B. However, a hydraulic motor or the like may be used.

  In addition, the rotational speed of the drive motor 45 may be changed in accordance with a change in travel speed due to the switching of the transmission lever 13. As a result, the number of carrots drawn and conveyed to the drawing and conveying device 24 by increasing the traveling speed is increased, and when the conveying speed of the drawing and conveying device 24 is increased, the number of rotations of the drive motor 45 increases, and the rotary cutting blade Since the rotational speed of the shaft 44 is increased, the root of the bottom of the carrot root can be cut reliably, the work efficiency is improved, and the uncut root remains are reduced. This eliminates the need for excision and reduces the labor of the operator.

  Further, when the traveling speed is lowered, the number of carrots conveyed by the drawing / conveying device 24 is reduced. Therefore, it is not necessary to rotate the rotary cutting blade 44 at a high speed, and the number of rotations of the drive motor 45 can be reduced. The load applied to the output shaft 45a and the rotary cutting blade 44 is reduced, and the durability is improved.

  A root guide 46 for receiving the lower part of the root of the carrot being conveyed by the pulling / conveying device 24 is disposed at the front of the guide cover 43 in an inclined posture toward the lower front of the machine body. It is configured in a V shape or a tongue shape in a front view located above the central portion in the direction. Further, the root guide 46 is made of an elastic member such as rubber, and the base side (guide cover 43 side) of the root guide 46 is made thicker than the end side (front side of the machine body), thereby making the root root A cutting device 47 is formed.

  The root portion guide 46 is formed of a material that can be expanded and contracted by air in and out, and a space portion 46a is formed inside the root portion guide 46. When the air enters the front end side (front side of the machine body) of the space portion 46a, the root portion guide 46 expands. However, when air escapes from the front end side (front side of the machine body), the root guide 46 may be retracted to the non-guide action side (back side of the machine body).

  With the above configuration, the length of the ginseng planted in the field is increased by changing the length of the root guide 46 by allowing air to enter and exit the space 46a formed in the root guide 46 by a compressor or the like (not shown). By changing the length of the working area of the root guide 46 according to the difference in the difference, the transport speed of the pulling and transporting device 24, etc., the hair root at the bottom of the carrot root is formed in the slit 43s formed in the guide cover 43. Since the hair root can be surely cut by being guided and brought into contact with the cutting rotary blade 44, it is not necessary for the operator to remove the hair root manually after the harvesting operation, and the labor of the operator is reduced.

  The space 46a formed in the root guide 46 is placed in contact with the plurality of slits 43s formed in the guide cover 43 so that the root guide 46 is expanded and contracted by the air generated by the rotation of the cutting rotary blade 44. Therefore, it is not necessary to provide a compressor and the number of parts is reduced.

  The amount of air flowing into the space 46a increases as the rotation speed of the cutting rotary blade 44 increases, and the root guide 46 extends as the work speed increases. The hair roots can be guided to the slits 43s of the guide cover 43, so that it is not necessary for the operator to manually remove the hair roots after the harvesting operation, and the labor of the worker is reduced.

  Further, as shown in FIGS. 6 to 9, the left and right front sides in the winding region of the left and right nipping and conveying belts 18 and 18 constituting the pulling and conveying device 24 and in the vicinity of the upper portion of the front end portion of the hair root cutting device 47. The idle pulleys 48 and 48 are rotatably provided, and the left and right front idle pulleys 49 and 49 are freely rotatable in the winding region of the left and right nipping and conveying belts 18 and 18 and in the vicinity of the upper portion of the rear end portion of the hair root cutting device 47. Provided. The left and right upper drive pulleys 50a and 50a and the left and right lower drive pulleys 51a and 51a are attached to the lower end portions of the left and right rotating shafts 49a and 49a of the left and right front idle pulleys 49 and 49, respectively. Left and right upper driven pulleys 50b and 50b and left and right lower driven pulleys 51b and 51b are attached to the lower end portions of the left and right rotating shafts 48a and 48a of the pulleys 48 and 48, respectively.

  Furthermore, left and right support plates 52, 52 are provided between the left and right upper driven pulleys 50b, 50b and the left and right lower driven pulleys 51b, 51b of the left and right rotating shafts 48a, 48a. The left and right upper tension pulleys 53, 53 are rotatably provided at the upper part of the support plate 52, and the left and right lower tension pulleys 54, 54 are rotatably provided at the lower part of the support plates 52, 52. The upper tension pulleys 53 and 53 are arranged to be narrower than the left-right distance.

  Then, left and right upper support guide belts 55 and 55 are wound endlessly around the left and right upper drive pulleys 50a and 50a, left and right upper driven pulleys 51a and 51a, and left and right upper tension pulleys 53 and 53, respectively. By winding the left and right lower support guide belts 56, 56 around the lower drive pulleys 51a, 51a, the left and right lower driven pulleys 51b, 51b, and the left and right lower tension pulleys 54, 54 in an endless manner, An upper support guide device 57 and a lower support guide device 58 are configured to prevent the carrots being conveyed from being shaken in the left-right direction and escaping from the root cutting device 47.

  By combining the upper support guide device 57 and the lower support guide device 58, a carrot support guide device 59 is configured. By combining the pulling and conveying device 24, the hair root cutting device 47, and the carrot support guide device 59, a 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 up and moved to the nipping and conveying start end of the pulling and conveying device 24, so that the ginseng stems and leaves are securely held by the pulling and conveying device 24 and pulled out from the field. The remaining ginseng is reduced and the work efficiency is improved.

  Further, weed bodies 42, 42 are provided on the upper projections 40, 40 at the tip of the soira 37, 37, and the stems and leaves that have been laterally raised and the device 26 has failed to take over are scooped up by the weed body 42, and are guided through the guide bars 41, 41. By adopting the structure in which the foliage is guided to the holding start end of the pulling and conveying device 24, the foliage is more securely held by the pulling and conveying device 24 and pulled out from the field, so that the carrots left behind are reduced and the work efficiency is reduced. improves.

  Moreover, by scooping up 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 field 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 erroneous operation 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.

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.
And by arranging the bases of the left and right earthing bars 38, 38 on the left and right vibrating arms 33, 33 that vibrate the left and right soilers 37, 37, the earthing bars 38, 38 together with the soilers 37, 37 are in the vertical direction of the fuselage. Therefore, the soil attached to the carrot can be scraped off in the vertical direction, and the carrot body also vibrates, so that the soil where the soil dropping bars 38 and 38 do not contact can also be dropped by vibration. This makes it easier for the sorting operator to discriminate carrot scratches (breaks, breaks, bruises, rot, etc.) and shape abnormalities (such as bifurcation, excessive bending, or minimum), thereby improving the carrot sorting accuracy.

  Further, by attaching the bases of the earthing levers 38, 38 to the side opposite to the bases of the soliters 37, 37 of the vibrating arms 33, 33, the earthing bars 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 drop levers 38, 38 from coming into contact with the carrot on the unexcavated side, thereby 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.

  Further, by arranging the action portions on the end side of the earth dropping bars 38, 38 in a substantially horizontal posture with respect to the field scene, the carrots conveyed in the rearward upward inclination direction by the pulling and conveying device 24 fall on the earth bars 38, When passing through 38, the top and bottom ends of the carrots fall and come into contact with the bars 38, 38, so that the soil adhering to the carrots can be surely scraped down in the vertical direction. Since it becomes easy to discriminate carrot scratches and shape abnormalities, the accuracy of ginseng sorting is improved.

  Further, since the earth dropping bars 38, 38 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 body structure is simplified. , Assembly and maintenance of the fuselage are facilitated.

  And, by forming the gap between the dumping bars 38, 38 on the front side of the machine body widest and narrowing the rear side of the machine body, when a crop with a larger upper diameter than a lower diameter passes like a carrot, the earthfall bar Since it can pass without being caught between the left and right of 38, 38, the harvesting work of the carrot 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 side of the sandfall bars 38, 38 is formed narrow, when the small-diameter carrot passes, it contacts the sandfall bars 38, 38 at least near the narrowest rear end of the sandfall bars 38, 38. 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.

  Further, by bending the narrowest portion between the left and right sides of the earthing bars 38, 38 outward in the left-right direction, the rear ends of the earthing bars 38, 38 do not come into contact with carrots, but come into contact with rounded bent parts. Therefore, the carrot is prevented from being damaged, and the commercial value is improved.

  In addition, since the earth dropping bars 38 and 38 are made of an elastic metal such as a piano wire, even if a ginseng having a diameter larger than the left-right distance passes between the right and left sides of the earth dropping bars 38 and 38, Since 38 and 38 can be retreated in the left and right outer direction, it is prevented that the carrot is clogged and does not move and the work is interrupted, and the work efficiency is improved.

  Further, by providing a cover 39 made of a soft material such as polyvinyl chloride, sponge, urethane or the like on the earthing bars 38, 38, the distance between the left and right of the earthing bars 38, 38 and the diameter of the carrot are the same or larger. Since it is a diameter and it can prevent excessive pressure being applied to the ginseng when the earth dropping bars 38, 38 are in close contact with the surface of the carrot, the carrot is prevented from being damaged and the commercial value is improved.

  Further, since the earth dropping bars 38 and 38 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 carrot 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 sides of the earth dropping bars 38, 38, and the angle adjustment of the earth dropping bars 38, 38 can be performed separately on the left and right sides by not connecting the left and right sides. Since it can, it can respond to various working conditions.

Since the root at the bottom of the root is guided to the slit 43s formed in 43 and brought into contact with the cutting rotary blade 44, it can be cut reliably, so that it is not necessary for the operator to manually remove the root after harvesting. , Labor of workers is reduced.

  In addition, the left and right side portions of the root guide 46 are positioned above the central portion in the left-right direction, and are formed in a V shape (tongue shape) when viewed from the front, so that the carrot that contacts the root guide 46 escapes in the left-right direction. Therefore, it is possible to reliably cut the hair root under the carrot root by contacting the cutting rotary blade 44, so that it is not necessary for the operator to remove the hair root manually after the harvesting work. The labor of the person is reduced.

Further, since the root guide 46 is made of an elastic member such as rubber, even if the carrot is in contact with the root guide 46 vigorously, it is difficult to be damaged, so that the commercial value of the carrot is maintained.
Since the base side (guide cover 43 side) of the root guide 46 is thicker than the end side (front side of the machine body), the end side of the root guide 46 is easily bent when it comes into contact with the carrot. Since the root of the lower part of the root can be reliably cut by contacting the cutting rotary blade 44, it is not necessary for the operator to manually remove the root after the harvesting operation, and the labor of the operator is reduced.

  Further, by providing a carrot support guide device 59 including an upper support guide device 57 and a lower support support device 58 below the pulling and conveying device 24 and above the hair root cutting device 47, the upper portion of the hair root cutting device 47 is provided.

This eliminates the need for removing the root of the hair and reduces the labor of the operator.

  Further, the left and right front idle pulleys 49, 49 provided on the pulling / conveying device 24 with driving forces to the left and right upper drive pulleys 50a, 50a of the upper support guide device 57 and the lower drive pulleys 51a, 51a of the lower support guide device 58 are provided. The configuration obtained from the left and right rotating shafts 49a, 49a eliminates the need for a new transmission mechanism for supplying driving force to the carrot support guide device 59, simplifies the configuration of the fuselage, and improves maintainability. The number of parts is reduced.

  Since the left and right lower tension pulleys 54 and 54 of the lower support guide device 58 are arranged to be narrower than the left and right distances between the left and right upper tension pulleys 53 and 53 of the upper support guide device 57, the upper support guide device 57 becomes a carrot. Since the contact position and the position where the lower support guide device 58 contacts the carrot can be different, the upper support guide device 57 and the lower support guide device 58 can easily come into contact with the roots of carrots having different thicknesses in the upper and lower sides. The carrot is prevented from being shaken from side to side, and it is not necessary for the operator to manually remove the hair root after the harvesting operation, thereby reducing the labor of the operator.
