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.
Furthermore, the leaf removal shooter 47 for discharging the leaf leaves cut from the carrots by the stem cutting devices 46, 46 of the harvesting section C (the cut leaf portions) to the field is already dug (the side where the carrots have been harvested). It is provided in a downward inclined posture so that the leaves and leaves are discharged, so that the discharged leaves and leaves fall on the carrots on the undigged side (the side where the carrots are not harvested), and the discharged leaves are sandwiched between the left and right transport belts 19 and 19 and the left and right driven pulleys 17 and 17 are entangled to stop the harvesting section C and prevent the harvesting operation from being hindered, so that the work efficiency is improved and the ginseng from which the fallen leaves falling on the carrot are harvested. Can be prevented from interfering with the visibility.

  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 opposite side of the bases of the soira 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 dropping 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 shape abnormalities, so that the carrot sorting accuracy is improved.

  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 for 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.

  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.

  As described above, by providing the shooter 65 so as to be pivotable up and down, when the shooter 65 is pivoted downward, the carrot is gently dropped in a container 69 such as a container or a flexible container bag installed in the container F described later. 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 65 is turned upward, it becomes a stopper that closes the terminal end side of the sorting and conveying conveyor 64. Therefore, when replacing a container full of carrots, the carrot can be moved without stopping the sorting and conveying conveyor 64. 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, to improve the quality of the carrot and to frequently turn the power of the sorting and conveying conveyor 64 on and off. The work efficiency is improved.

  Further, since the shooter 65 is rotated upward to serve as a stopper and the sorting / conveying conveyor 64 is not stopped, ginseng accumulates on the terminal side of the sorting / conveying conveyor 64. Since the carrots that have been brought into contact with the carrots staying at the conveyance start end of the sorting and conveying conveyor 64 are prevented from being damaged, the product value of the carrots is improved.

  Further, by attaching an operation lever 66 for turning the shooter 65 up and down on the left and right outer sides of the shooter 65, the auxiliary worker can turn the shooter 65 up and down while sitting on an auxiliary work seat 74 described later. The labor of auxiliary workers is reduced.

Next, the accommodating part F is demonstrated.

  Then, a support frame 73 bent over the storage container loading table 72 and toward the sorting and conveying conveyor 64 is attached to the outside of the machine body of the storage container loading table 72, and an auxiliary worker is mounted on the support frame 73. An auxiliary work seat 74 on which is seated is attached. And the 2nd preliminary storage container mounting base 75 which installs the preliminary storage container 69 in the rear part of the said storage container mounting base 72 is attached, and the storage part F is comprised.

  As described above, the other end of the telescopic damper 68 is attached to the storage container table 70 provided in the upward inclined posture, so that the storage container table 70 is lowered as the carrot is stored in the storage container 69 and becomes heavier. Therefore, since ginseng is prevented from being biased into a part of the storage container 69, the frequency of replacement of the storage container 69 is reduced, and the labor of the operator is reduced.

  Further, the provision of the preliminary storage container stand 71 for installing the spare storage container 69 at the rear of the storage container stand 70 allows the damper 68 to extend when the storage container 69 full of carrots is removed from the storage container stand 70. Since the storage container table 70 returns to the upward inclined posture and the storage container 70 installed on the preliminary storage container table 71 slides down on the storage container table 70, it is not necessary to manually install the storage container 69. The labor efficiency of the worker is reduced and the work efficiency is improved.

  The storage container loading platform 72 is attached to the left and right outer sides of the machine body so as to be foldable to the inside of the machine body, so that the container storage platform 72 is folded to the inside of the machine body when going to the field or when returning from the farm field. Since it can be made compact, it can be easily loaded on a small truck and the transportability is improved.

  Further, by providing the auxiliary work seat 74 on the support frame 73 that is bent over the storage container loading table 72 and toward the sorting and conveying conveyor 64, the auxiliary worker can be positioned near the sorting and conveying conveyor 64. Since the sorting operation can be performed, the sorting accuracy is improved, and the operation efficiency is improved because the storage container 69 is not hindered from moving on the storage container mounting table 72.

  In addition, since the second preliminary storage container pedestal 75 is attached to the rear portion of the storage container loading table 72, a large number of storage containers 69 can be mounted on the machine body, so that the harvesting operation is continued continuously for a long time. Work efficiency is improved.

Hereinafter, another embodiment of the ginseng harvester will be described.
As shown in FIG. 11, it is good also as a structure which forms the flat part f flat in a side view on the base part side of the right and left earthfall bars 38,38.

  With the above configuration, the spring constant k1 in the left and right direction of the earth dropping bars 38 and 38 is lower than that in which the flat portion f is not provided, and when the large-diameter carrot falls and passes between the left and right sides of the bars 38 and 38, Since the drop bars 38 can be opened flexibly toward 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, the vertical spring constant k2 of the earth dropping bars 38, 38 is substantially the same as that of the flat bar f not provided, and can vibrate in the vertical direction according to the vibration of the vibration device 36. Since the soil adhering to the soil is surely scraped off in the vertical direction, it becomes easier for the sorting operator to discriminate carrot scratches and shape abnormalities, so that the accuracy of carrot sorting is improved.

The flat portion f may be configured by crushing the base of the earthing bars 38, 38, or may be configured by replacing the base of the earthing bars 38, 38 with a thin spring plate such as a leaf spring. .
As shown in FIGS. 12 (a) and 12 (b), the covers 39 and 39 may be composed of corrugated tubes 39a and 39a having irregularities formed at equal intervals, as shown in FIGS. 13 (a) and 13 (b). Alternatively, it may be constituted by spiral tubes 39b and 39b which are spirally dropped and wound around the bars 38 and 38.

  With the above configuration, when the corrugated tubes 39a and 39a and the spiral tubes 39b and 39b come into contact with the carrot, it is possible to apply resistance to the carrot in the direction opposite to the conveyance direction, so that the soil adhering to the carrot can be more efficiently dropped. This makes it easier for the sorting operator to discriminate carrot scratches and shape abnormalities, thus improving the carrot sorting accuracy.

  As shown in FIG. 14, covers 39 c and 39 c having a plurality of protrusions may be attached to the earth dropping bars 38 and 38. The projections of the covers 39c and 39c are configured to bend flexibly in the front-rear direction and not bend in the vertical direction.

  According to the above configuration, the soil adhered to the carrot that has come into contact can be efficiently dropped, and when the large-diameter carrot falls and passes between the left and right sides of the bars 38, 38, the earth dropping bars 38, 38 The protrusions of the covers 39c and 39c are retracted in the front-rear direction according to the diameter of the carrots while retracting in the left and right outer directions, so that the carrots are less likely to be clogged and the work efficiency is improved.

Note that the length of the protrusions of the covers 39c and 39c is longer on the front side of the fuselage and shorter on the rear side of the fuselage, thereby further preventing the carrot from being clogged.
Further, as shown in FIGS. 15A and 15B, tube-shaped covers 39d and 39d that are longer than the longitudinal lengths of the earth dropping bars 38 and 38 and in which cut portions are formed at a plurality of positions may be used.
With the above configuration, the operator can form or remove any number of protrusions of any number in any position by pulling or shrinking the covers 39d, 39d. It is possible to make the soiling bars 38 and 38 correspond to various working conditions, and the work efficiency is improved, and the soil is efficiently removed, so that it becomes easy for the sorting worker to identify carrot scratches and shape abnormalities. Sorting accuracy is improved.

  As shown in FIGS. 16 (a) and 16 (b), instead of the left and right mud dropping bars 38, 38, a tapered scraper 76 that scrubs the soil adhering to the carrots inside the left and right soiler frames 32, 32. , 76 may be attached so as to be rotatable in the longitudinal direction of the machine body. The scrapers 76 and 76 are made of a soft material such as rubber or polyvinyl chloride that is somewhat rigid. The scrapers 76 and 76 are configured such that the left-right distance on the front side of the machine body is wide and the left-right distance on the rear side of the machine body is narrow. The scrapers 76 and 76 are provided with cuts in the left-right direction of the machine body at equal intervals.

  With the above configuration, when the carrot transported in the rearward and upward inclined direction by the pulling and transporting device 24 passes through the left and right scrapers 76 and 76, the upper and lower ends of the carrot contact the scrapers 76 and 76. Since the adhered soil can be surely scraped off in the vertical direction, it becomes easier for the sorting operator to discriminate carrot scratches and shape abnormalities, so that the carrot sorting accuracy is improved.

  And by arranging the left and right widths of the scrapers 76, 76 so that the front side of the machine body is widest and narrows toward the rear side of the machine body, when crops having an upper diameter larger than the lower diameter pass like carrots Since it can pass without being caught between the left and right of the scrapers 76, 76, the carrot harvesting operation is not interrupted, and the work efficiency is improved. Further, since the soil adhering to the carrot can be surely scraped down in the vertical direction, it becomes easier for the sorting operator to discriminate the carrot's scratches and abnormal shapes, so that the carrot sorting accuracy is improved.

  As shown in FIG. 17, since the scrapers 76 and 76 can be rotated in the longitudinal direction of the machine body, the working angle of the scrapers 76 and 76 can be arbitrarily changed. An appropriate angle can be set according to conditions such as quality, condition, and quantity of the soil, and the soil attached to the carrots is removed more efficiently, making it easier for the sorting operator to identify carrot scratches and shape abnormalities. , Improve the carrot sorting accuracy.

  In addition, when the amount of soil is small and it easily falls when it comes into contact with the scrapers 76, 76, when the scrapers 76, 76 are installed in a substantially horizontal state with respect to the field scene, the carrots are rearward and obliquely upward by the pulling and conveying device 24. The scrapers 76 and 76 can be uniformly contacted from the upper end portion to the lower end portion while being conveyed.

  Conversely, when the amount of soil is large, or when it is desired to reduce the amount of soil remaining in the carrots as much as possible, the angles (30 °, 45 °, 75 °, 90 °) for bringing the scrapers 76, 76 perpendicular to the field scene. Etc.), the scrapers 76 can be brought into contact with the carrot in the vertical direction.
