The driven sprockets 47, 47 are pressed by the tension springs 50, 50 to the front side and toward the inner side of the machine body, and when the large diameter foliage passes, the aligned sprockets 47, 47 are moved to the outer side of the machine body. Therefore, it is possible to prevent the large-diameter foliage portion from being bitten, and it is not necessary to remove the bitten foliage portion, thereby improving work efficiency.

  In addition, the left-right distance from the conveyance start end side to the conveyance end side of the alignment devices 54, 54 becomes substantially linear only when a large diameter foliage part passes through and is loaded, so in other cases Has a configuration in which the left and right intervals of the alignment device are widened from the conveyance start end side toward the conveyance end side, so that ginseng passing through the left and right intervals of the alignment devices 54 and 54 can be prevented from fluctuating in the left and right direction. Cutting position alignment is performed properly.

  Further, the large diameter foliage part cannot pass between the right and left of the alignment devices 54, 54, the cutting position of the carrot foliage part is raised too much, and the foliage part can be prevented from remaining in the root part. The work efficiency is improved, the work efficiency is improved, the ginseng is lifted too much, and the root part can be prevented from being cut by the foliage cutting device 61, which will be described later. improves.

  A plurality of link pins 48a... Constituting the alignment chains 48, 48 cover a contact surface between the upper surface, the lower surface, and the foliage of the alignment chains 48, 48. Are attached to form the alignment guide body 52.

  As shown in FIG. 10, the guide covers 51 are formed in a U shape when viewed from the front or the back, and the guide covers 51 interfere with each other by attaching one to the link pins 48a. Since the movement of the alignment chains 48, 48 can be followed without any movement, the movement of the alignment devices 54, 54 becomes smooth, and the work efficiency is improved.

  Then, the alignment chains 48, 48 are placed in the winding area of the alignment chains 48, 48 and between the alignment driven sprockets 45, 45 and the alignment tension sprockets 47, 47 from the winding area to the foliage contact surface. The left and right tension plates 53L and 53R are attached to the left and right sides of the machine body so that the positions of the left and right tension plates 53L and 53R are adjustable. .

  The tension plates 53L and 53R are formed with elongated holes in the transmission cases 37 and 37, and the mounting shafts 53a and 53a are attached to the position adjustment by detachable members such as bolts, and a plate is attached to the ends of the mounting shafts 53a and 53a. The bodies 53b and 53b are welded.

  The left and right cutting blade rotation shafts 56 and 56 are attached to the rear positions of the alignment devices 54 and 54 of the left and right first gear units 38 and 38, and the left and right bearings 57 and 56 are attached to the cutting blade rotation shafts 56 and 56, respectively. 57 is attached rotatably. Then, left and right support plates 59, 59 are attached to the left and right bearings 57, 57, and left and right foliage cutting blades 60, 60 are attached to the support plates 59, 59 to constitute a foliage cutting device 61.

  Further, left and right foliage conveyance drive pulleys 62 and 62 are attached to the left and right first output shafts 40 and 40, and the left and right first and second gear units 38 and 38 are positioned in front of the machine body and above the alignment devices 54 and 54. The foliage driven pulleys 63 and 63 are rotatably attached. Then, the left and right foliage conveying belts 64, 64 are wound around the left and right foliage conveying drive pulleys 62, 62 and the left and right foliage conveying driven pulleys 63, 63 to endlessly form the carrot foliage from the pulling and conveying device 24. Is disposed on the outer periphery of the upper part of the left and right transmission cases 37 and 37 on the lower end side of the transporting end of the pulling transporting device 24.

  Further, left and right remaining leaf conveyance drive pulleys 66 and 66 are pivotally attached to the upper ends of the left and right first output shafts 40 and 40, and the left and right remaining leaf conveyance driven pulleys 67 and 67 are rotatable above the transmission cases 37 and 37. A plurality of left and right remaining leaf conveyance tension pulleys 68, 68 are attached between the left and right remaining leaf conveyance driving pulleys 66, 66 and the left and right remaining leaf conveyance driven pulleys 67, 67. Then, left and right residual leaf conveyance belts 69, 69 are wound endlessly around the left and right residual leaf conveyance driving pulleys 66, 66, left and right residual leaf conveyance driven pulleys 67, 67, and left and right residual leaf conveyance tension pulleys 68, 68. Thus, the remaining leaf conveyance device 70 that sandwiches the upper part of the foliage and conveys it to the rear of the machine body is configured above the defoliation conveyance device 65.

A foliage shooter 71 for discharging the foliage cut by the foliage cutting device 61 from the end portions of the above-mentioned foliage conveyance device 65 and the remaining leaf conveyance device 70 to the field is provided to constitute the foliage cutting portion D.
Further, as shown in FIG. 7, the left and right nipping and conveying belts 18 and 18 that constitute the pulling and conveying device 24 and above the conveying start end side of the left and right alignment devices 54 and 54 and the leaflet conveying device 65 are wound. Within the circulation zone, a plurality of conveyance auxiliary rollers 128 are arranged to rotate freely at predetermined intervals in the front-rear direction while nipping and conveying the carrot foliage so that the root portion contacts the alignment devices 54, 54. The conveyance auxiliary roller 128 has a holding rotary body 128a for pinching the ginseng stalks and leaves under the conveyance auxiliary rotation shaft 128c, and a handling rotation body for handling and lifting the ginseng stalks and leaves above the conveyance auxiliary rotation shaft 128c. 128b is pivotally configured. At this time, the handling rotary body 128b is configured to have a smaller diameter than the sandwiching rotary body 128a.

The conveyance auxiliary roller 128 may be a “convex” -shaped or “rho” -shaped atypical roller in which the upper diameter is smaller than the lower diameter.
With the above-described configuration, the left and right alignment drive sprockets 42 and 42 are arranged at positions spaced from the left and right spacing portions of the alignment devices 54 and 54 through which the foliage passes. Since it is possible to prevent the stems and leaves from being entangled with the two output shafts 41 and 41 to stop the alignment devices 54 and 54, the harvesting operation is not interrupted and the work efficiency is improved.

  Further, since the alignment drive sprockets 42 and 42 have a smaller diameter than the alignment driven sprockets 45 and 45 and the alignment tension sprockets 47 and 47, the alignment drive sprockets 42 and 42 are further left and right of the alignment devices 54 and 54. Since it leaves | separates from a space | interval part, it can further prevent that a foliage part gets entangled with the alignment drive sprockets 42 and 42 and the 2nd output shafts 41 and 41, and working efficiency further improves.

  The left and right tension springs 50 and 50 for tensioning the alignment driven sprockets 45 and 45 are provided, so that the left and right alignment chains 48 and 48 are generated when the foliage comes into contact with the alignment devices 54 and 54. Since the slack can be absorbed and the alignment chains 48 and 48 immediately return to the tensioned state, the alignment devices 54 and 54 ensure that the ginseng foliage even when the foliage portions having different diameters pass continuously. The cutting position of the carrot foliage is properly aligned and the foliage is cut appropriately, and there is no need to remove the foliage in a later process, improving the work efficiency.

  Further, the tension of the tension springs 50, 50 is adjusted by moving the left and right receiving plates 49, 49 in the front-rear direction, so that the growth status of the carrots, the difference in the diameter of the foliage depending on the variety, or the weather and soil quality The tension can be changed appropriately according to the working conditions at the work place, etc., so that the stems and leaves remaining in the carrots are removed in the subsequent process by properly aligning the carrot foliage cutting position and cutting the foliage parts reliably. This eliminates the need for work efficiency.

  Further, the left and right alignment frames 43, 43 are formed with holes 44, 44 in the left-right direction of the machine body, and the rotation shafts 46, 46 having the alignment driven sprockets 45, 45 attached to the holes 44, 44 are movable. In the state where no load is applied, the alignment driven sprockets 45, 45 tensioned by the tension springs 50, 50 move toward the conveyance path of the foliage portion, so that the small diameter foliage portion passes through. In addition, the alignment devices 54 and 54 can receive the foliage portion to properly align the cutting position of the ginseng foliage portion, so that it is not necessary to remove the foliage portion remaining in the ginseng in the subsequent process, and the work efficiency is improved.

  Further, when a large load is applied to the left and right alignment devices 54 and 54 when the large diameter foliage part passes, the alignment driven sprockets 45 and 45 are separated from the movement path of the foliage part along the holes 44 and 44. Therefore, the front left and right intervals of the alignment devices 54 and 54 are widened, so that the foliage portion can be prevented from being caught in the interval portions of the alignment devices 54 and 54, and the body is stopped and bitten. There is no need to remove the foliage and the work efficiency is improved.

  If it is known before harvesting that the carrot foliage has a large diameter, move the alignment driven sprockets 45, 45 away from the left and right of the left and right alignment devices 54, 54. If the left and right intervals on the upper side in the conveying direction of the alignment devices 54 and 54 are widened, the alignment devices 54 and 54 can be prevented from biting the foliage, and the work of removing the bited foliage is necessary. No work efficiency is improved.

  Since the guide cover 51 is attached to each of the plurality of link pins 48a constituting the alignment chains 48, 48 to constitute the alignment guide body 52, the guide cover 51 at an arbitrary position can be freely attached and detached. Even if a part of the guide covers 51 is damaged, it is possible to maintain proper alignment performance simply by replacing the guide covers 51 with new guide covers 51, and the foliage portions are appropriately cut, so that the work efficiency is improved.

Moreover, since it is not necessary to replace the entire alignment guide body 52, the cost can be reduced.
Furthermore, since the guide cover 51 can be attached and detached manually without the need for a tool, the replacement work can be easily performed.

  Since the guide cover 51 has a U-shape in front view covering the contact surfaces of the upper and lower surfaces of the alignment chain 48 and the foliage, a space portion is generated between the guide cover 51 and the alignment chain 48. As a result, the foliage is sandwiched between the guide cover 51 and the alignment chain 48, so that ginseng is not aligned at the proper cutting position and the foliage is left uncut, and the foliage is removed in a later process. The work efficiency is improved, the carrot root is prevented from being cut, and the product value of the carrot is improved.

  When the right and left tension plates 53L and 53R are provided in the winding region of the alignment chains 48 and 48, the alignment chains 48 and 48 are pressed from within the winding region. The portions of the alignment chains 48, 48 that are not pressed by the tension plate 53L or the tension plate 53R can be retracted in the direction of the alignment drive sprockets 42, 42, so that the foliage is engaged between the left and right of the alignment devices 54, 54. There is no need to remove the foliage that has been bitten by stopping the airframe, and the work efficiency is improved.

  And the leaf shooter 71 which discharges the leaf leaves cut from the carrot by the stem-and-leaf cutting device 61 (the cut stem and leaf portion) to the field seems to discharge the leaves and leaves to the already dug side (the side where the carrot has 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.

  Further, a plurality of auxiliary conveyance rollers 128 are provided in the winding region of the left and right nipping and conveying belts 18, and the upper handling rotary body 128b constituting the auxiliary conveying roller 128 has a smaller diameter than the lower holding rotary body 128a. When the left and right foliage parts pass between the auxiliary conveyance rollers 128 and 128, the lower side of the left and right nipping conveyance belts 18 and 18 is closed and the foliage part is nipped, and the upper side is opened and the root part is opened. Therefore, when the carrots move to the alignment devices 54, 54, the foliage portions sandwiched and transported by the pulling / conveying device 24 are removed. Since it does not move upward or downward, it is prevented from being cut off, so that the carrot does not fall in the middle of transportation, and there is no need to manually process the remaining leaves after the harvesting work. Is reduced That.

In addition, since the carrot falls outside the machine and the conveyance path, it is not necessary for the worker to pick up the dropped carrot, so that the labor of the worker is reduced.
And since the frequency which adjusts according to the kind and growth state of the ginseng which harvests the right-and-left space | interval of the left and right conveyance auxiliary rollers 128 and 128 according to the conventional technique decreases, There is no need to interrupt the work to adjust the left-right distance, and work efficiency is improved.

  In this configuration, even if the diameter of the foliage is large, the left and right nipping and conveying belts 18 and 18 behave in the same manner as when the foliage is thin or has a standard diameter, and therefore the frequency of adjustment is reduced. An exception is the presence of large ginseng (3L to 4L class) outside the standard, but such ginseng is usually used for processing or distributed to the market because producers select them before shipping. Since it is neither a thing nor a thing which appears frequently, even if a foliage part breaks and falls, work efficiency and the labor of an operator are not impaired.

  In addition, as shown in FIG. 13, among the plurality of guide covers 51 constituting the alignment devices 54, 54, hemispherical conveyance protrusions 51a projecting to the left and right spacing portions through which the foliage passes are provided, and left and right left and right positions are provided. The aligning devices 54, 54 are configured by shifting the left and right alignment chains 48, 48 by one link pin 48a so that the conveying protrusions 51a, 51a are arranged in a phase that is not adjacent. Further, as shown in FIG. 12, when the lower end portion of the link pin 48a is formed with a dish-shaped or hemispherical grip portion 48t, the grip portion 48t is formed at the upper end portion of the carrot root portion contacting the lower portions of the alignment devices 54, 54. Since slippage can be prevented by contact, the alignment of the cutting position of the foliage part is performed stably, so it is difficult for the remaining leaves to remain in the carrots, and the operator is responsible for processing the remaining leaves in the carrots. Omitted.

  The transport protrusion 51a can be configured by an inexpensive and simple operation when a hemispherical rivet is used for the guide cover 51. However, a female screw hole (not shown) is formed in the guide cover 51, and If a pan screw with a screw groove (screw with a cross or a single groove for a driver formed in a hemispherical head) is screwed in, it will be easy to adjust the protrusion of the conveying protrusion 51a, and the carrot The adaptability to working conditions such as cultivar and growth state of the plant is improved.

  Further, as shown in FIG. 15, a U-shaped notch groove 51b is formed in the front-rear direction center portion of the guide cover 51 in the vertical direction in a plan view or a bottom view, and the transport protrusion 51a is formed before and after the notch groove 51b. It is good also as a structure attached to each. At this time, the conveyance protrusion 51a may be formed of either a rivet or a pan screw.

In either case of FIGS. 11 and 15, as shown in FIG. 14, a plurality of conveying protrusions 51 a may be arranged side by side in the vertical direction.
Next, the takeover conveyance unit E will be described.

  As shown in FIG. 2, front and rear remaining leaf processing frames 72a and 72b are provided below the foliage cutting device 61, and left and right residual leaf processing rollers 73 between the left and right sides of the front and rear remaining leaf processing frames 72a and 72b. 73 are rotatably mounted. Then, a remaining leaf treatment belt 74 made of an elastic material such as rubber or urethane is wound endlessly around the left and right remaining leaf treatment rollers 73, 73, and the residue remaining at the root of the carrot is left above the remaining leaf treatment belt 74. A remaining leaf processing roller 75 is attached to rotate and cut the leaf together with the remaining leaf processing belt 74, and the remaining leaves of the carrots taken over from the stem and leaf cutting part D are processed and transferred from the outer side of the machine body to the left and right inner side. A leaf processing conveyor 76 is configured.

Then, the pumping conveyance belt 80 is wound endlessly around the pumping conveyance driving roller 78 and the pumping conveyance driven roller 79 on the front side of the machine body and adjacent to the residual leaf processing conveyor 76 with respect to the residual leaf processing conveyor 76. A pumping conveyer 81 is formed which takes over the carrot from the remaining leaf processing conveyor 76 and the cradle 77 and pumps it to the left and right sides of the machine body.

A pumping conveyance unit E is constituted by the remaining leaf processing conveyor 76 and the pumping conveyance conveyor 81 provided in the upward inclined posture.
With the above configuration, the remaining leaf processing roller 75 constituting the remaining leaf processing conveyor 76 transports the carrots to the uplifting conveyor 81 while cutting off the remaining leaves of the carrots cut and left by the stem and leaf cutting device 61. 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.

  In addition, the remaining leaf processing belt 74 constituting the remaining leaf processing conveyor 76 is made of an elastic body such as rubber or urethane, so that the remaining leaf processing belt is removed even if carrots fall after the leaves are cut off by the foliage cutting device 61. Since 74 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 77 on the starting end side of the remaining leaf processing conveyor 76 and on the front side of the machine body in a downward inclined posture, the foliage part fell off on the front side of the machine body from the foliage cutting device 61 and dropped. The carrot can be received without being dropped outside the machine, and the received carrot can be moved toward the pumping conveyor 81, so that the work of collecting the carrot that has fallen outside the machine after the harvesting work is omitted. The labor of the worker is reduced, and the carrot dropped on the front side of the machine body from the foliage cutting device 61 can be returned to the conveyance path, so that the work efficiency is improved.

Next, the sorting and conveying unit F will be described.

  As in the above configuration, by providing automatic tension mechanisms 84a and 84a to which sorting and conveying driven sprockets 84 and 84 are rotatably attached, the transmission chains 85 and 85 can be attached when the carrot falls from the pumping and conveying conveyor 81. Since it can be bent, the carrot is prevented from being damaged by absorbing the impact of the fall, and the commercial value of the carrot is improved.

  In addition, since the sorting and transporting drive sprockets 83 and 83 are provided on the transport end portion side, even if the automatic tension mechanisms 84a and 84a work and the transmission chains 85 and 85 are bent, the transport end position of the sorting and transporting conveyor 87 does not change. Therefore, the distance between the sorting and conveying conveyor 87 and the storage container 93 is prevented from changing, the carrot falling distance is kept constant, and it is prevented from being damaged by the impact of dropping.

  And by arranging the conveyance end portion of the draw-up conveyance conveyor 81 across the automatic tension device 84a on the left and right sides of the machine body, the carrots discharged from the draw-up conveyance conveyor 81 are separated from the automatic tension device 84a and the transmission chain 85. Since the carrot does not fall, the automatic tension device 84a acts when the carrot falls, so that the transmission chain 85 bends firmly, so that the impact of the fall is absorbed and the carrot is prevented from being damaged.

  Furthermore, since the sorting and conveying conveyor 87 is configured by providing a plurality of conveying bars 86 at equal intervals between the left and right of the left and right transmission chains 85, 85, the mud adhered to the carrot from between the conveying bars 86. As a result, it is possible to prevent foreign substances such as leaf dust and leaves from falling down, so that the foreign substances are prevented from concealing the shape and scratches of the carrots to be sorted, and the carrot sorting accuracy is improved.

  In addition, since the shooter 88 is provided so as to be pivotable up and down, when the shooter 88 is pivoted downward, the carrot can be gently dropped into a container 93 such as a container or a flexible container bag installed in the container G described later. In addition, the carrots are prevented from being damaged by the impact of falling, and the product value of the carrots is improved.

  When the shooter 88 is rotated upward, it becomes a stopper that closes the terminal end side of the sorting and conveying conveyor 87. Therefore, when replacing a container full of carrots, the carrot can be moved without stopping the sorting and conveying conveyor 87. 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, improve the quality of the carrot, and to frequently turn on and off the power of the sorting and conveying conveyor 87. The work efficiency is improved.

  Further, by rotating the shooter 88 as a stopper and not stopping the sorting / conveying conveyor 87, the carrot accumulates on the terminal end side of the sorting / conveying conveyor 87. Since the carrots that have been brought into contact with the carrots staying at the transport start end of the sorting and conveying conveyor 87 are prevented from being damaged, the product value of the carrots is improved.

  Further, by attaching an operation lever 89 for turning the shooter 88 up and down on the left and right outer sides of the body of the shooter 88, the auxiliary worker can turn the shooter 88 up and down while sitting on an auxiliary work seat 117 described later. The labor of auxiliary workers is reduced.

  Further, when the mounting arm 100, 100 of the step 99 is rotated around the rotating stays 101, 101 and the storage base 103 is rotated toward the body frame 1, the step 99 is rotated toward the storage base 103. Also good.

  According to the above configuration, when the storage table 103 is rotated upward, the step 99 is also rotated upward to be in an inclined posture, so that impurities such as mud and leaf waste dropped from the sorting and conveying conveyor 87 and the operator's shoes. Since it can be dropped downward, it is easy to remove foreign matters, and the maintainability is improved.

  At this time, if the surface of step 99 has a flat structure without unevenness or is covered with a material that is difficult to adhere mud, the mud is less likely to remain when step 99 is tilted, and the maintainability is further improved.

  A pair of left and right drive pulleys 104, 104 are provided at the front portion of the storage table 103, and a pair of left and right driven pulleys 105, 105 are provided at the rear portion of the storage table 103. The drive pulleys 104, 104 and the driven pulleys 105, 105 are provided. A plurality of transport rollers 106, 106... Further, two conveying belts 107, 107: 107, 107 are wound around the driving pulleys 104, 104 and the driven pulleys 105, 105 in an endless manner with a left-right interval. Between the left and right conveying belts 107, 107: 107, 107, the conveying rollers 106, 106... Are provided at positions where they do not contact the conveying belts 107, 107: 107, 107.

  When the upper surfaces of the conveying rollers 106, 106... And the conveying belts 107, 107: 107, 107 are positioned above the upper end surface of the storage table 103, the storage container 93 is conveyed in contact with the upper surface of the storage table 103. Since it is prevented from disappearing, work efficiency is improved.

Furthermore, a container motor 109 is configured by providing a drive motor 108 for driving and rotating the drive pulleys 104 and 104 at the front end of the storage table 103.
As shown in FIG. 2, when the storage container 93 comes into contact with the position where the storage container 93 is received from the storage container mounting base 97 on the left and right side walls of the storage base 103, the mounting motor 103 is driven for a predetermined time. When the position detection switch 110 is provided, the storage container 93 that stores the carrot can be automatically moved, so that the operation of moving the storage container 93 by the operator is omitted, and the work efficiency is improved.

The drive time of the drive motor 108 is a time required for one container 93 to move forward.
In addition, since the operator can concentrate on maneuvering the aircraft and the auxiliary worker can concentrate on the sorting operation, it is possible to prevent the carrot from being left behind and improve the accuracy of carrot sorting.

  Then, when the storage container 93 transported by the storage container transport device 109 comes into contact with the wall surface of the front end portion of the storage table 103, the drive motor 108 is stopped and a notification means (not shown) such as a buzzer or a lamp is detected. By providing the end detection switch 111, it becomes automatically recognized that the storage container 103 is full of storage containers 93 and cannot be stacked any more, and the work efficiency is improved.

  In addition, L-shaped mounting stays 112, 112 are fixed to the left and right ends of the rear end of the storage base 103, and the ends projected from the mounting stays 112, 112 in a plan view with a steel strip. A support frame 113 formed in a U-shape is fixed by a fixing pin 113a. A plurality of support pipes 114 are provided between the left and right sides of the support frame 113 to dispose a waste collection container 93t for collecting waste ginseng (growth defects, shape abnormalities, wounds, etc.) that are ineligible as commodities. A container support 115 is formed.

The fixing pin 113 a contacts the lower part of the lowest waste container 93 t and prevents the waste container 93 t from moving to the storage table 103.
The support frame 113 of the waste container support base 115 has a rearward upward tilting posture toward the rear of the machine body, and the tilt angle is set to allow the stacking of the waste containers 93t in a plurality of stages, for example, up to two stages. If the waste container support table 115 is at an angle (≈0 degrees) that is substantially horizontal to the field, many waste containers 93t can be stacked in the vertical direction, and the waste container support table 115 is broken by weight. There is a risk that. In addition, if many waste containers 93t are loaded on the waste container support stand 115 located at the rear end of the aircraft, the weight balance is concentrated on the rear of the aircraft, and the running posture and turning posture of the aircraft are disturbed. The position may shift. In order to prevent such a problem from occurring, the waste container support base 115 is in a back-up tilt posture so that an excessively large number of waste containers 93t cannot be loaded.

Note that the waste container support table 115 may be placed with an empty container or a container 93 that has received carrots.
Then, a U-shaped seat support frame 116 in a rear view is inserted into either the front or rear of the front and rear rotating stays 101, 101, and the carrots on the sorting and conveying conveyor 87 are sorted into the seat support frame 116. The accommodation part G is configured by attaching the auxiliary work seat 117 on which the worker sits.

In addition, you may attach the auxiliary | assistant work seat 117 rotatably in the left-right direction.
As in the above configuration, a plurality of rotating shafts 91a, 91b, 91c for attaching the conveying roller 92 to the storage container mounting table 97 are provided, and the rotating shaft 91a at the left and right side ends is positioned below the other rotating shafts 91b, 91c. As a result, when the storage container 93 is provided on the storage container mounting table 97, the left and right one side ends of the storage container 93 are inclined to be positioned below the left and right other side ends. Since it is prevented by the conveyance roller 92 from moving to the storage table 103 without permission, the carrot is accommodated as much as possible and then moved to the storage table 103, so that the work efficiency is improved.

  Moreover, since the container 93 which receives the carrot discharged from the sorting and conveying conveyor 87 can be moved without permission and the carrot is dropped on the field or the machine body, the carrot is prevented from being damaged by the impact of the fall. The product value is maintained, and the labor of picking up the carrots that have fallen is not necessary, reducing the labor of the worker.

  Since the rotation shafts 91b and 91c are arranged at substantially the same height, when the storage container 93 is placed on the transport roller 92 provided on the rotation shaft 91b when the storage container 93 is pulled out to the storage base 103, the rotation shaft 91c is placed on the rotation shaft 91c. Since the transport roller 92 moves without difference in height, the load when the operator pulls out the storage container 93 is reduced, and the storage container 93 filled with carrots can be moved with a light force.

  Further, since the divided conveying rollers 92x, 92y, and 92z obtained by dividing the conveying roller 92 are respectively attached to the rotation shafts 91a, 91b, and 91c, only the portion that comes into contact with the bottom portion of the storage container 93 rotates. The inertia per roller 92x, 92y, 92z can be reduced, and the operator can pull out the storage container 93 with a small force, thereby reducing the labor of the operator.

  Further, since the front-rear distance between the divided transport rollers 92x, 92y, and 92z and the front-rear distance between the divided transport rollers 92x and 92z located at the front and rear end portions and the placement support frame 90 hardly occur, the storage container 93 is provided. Since the bottom portion of the container can be prevented from getting caught in the interval, the container 93 can be moved smoothly to the storage table 103, and the work efficiency can be improved.

  Then, by providing the rotating shaft 91a with the brake body 94 and the adjustment knob 95 for adjusting the rotation speed, the farm field is stable, and the storage container 93 moves freely from the storage container mounting base 97 toward the storage base 103. When there is almost nothing, the restriction force of the rotating shaft 91a can be weakened to facilitate rotation, so that the operator can pull out the storage container 93 with a smaller force, thereby reducing the labor of the operator.

  On the other hand, when the storage container 93 tends to move freely from the storage container mounting base 97 toward the storage base 103, such as when the field is largely uneven and the aircraft is frequently tilted, the regulating force of the rotating shaft 91a is strengthened. Since the container 93 is restricted from moving by the transport roller 92 attached to the rotation shaft 91a even if the machine body is inclined, it is prevented from moving to the storage table 103 without permission. The carrots are prevented from falling and being damaged on the airframe or the field, thereby improving the commercial value of the crops, and it is not necessary to collect the carrots that have been dropped, thereby reducing the labor of the operator.

  The adjustment knob 95 may be tightened so that the rotation shaft 91a does not rotate at all. Further, the adjustment knob 95 may be configured to rotate with a motor, and a switch for driving the motor may be provided near the auxiliary work seat 117 so that the operator can turn the adjustment knob 95 without moving.

  Furthermore, by attaching one end of a damper 96 that expands and contracts in accordance with the weight of the storage container 93 to the storage placement frame 90, the storage container 93 is inclined when the carrot storage capacity is zero or small. Since the carrot discharged from the sorting and conveying conveyor 87 is received and the posture is changed to a horizontal posture as the accommodation amount increases, the falling distance of the carrot from the sorting and conveying conveyor 87 to the containing container 93 is shortened, and the impact of dropping The carrot is prevented from being damaged, and the commercial value is maintained.

Moreover, since the angle of the storage container 93 can be automatically changed, work efficiency improves.
And, by providing the conveyor belt 107, 107: 107, 107 and a plurality of conveyor rollers 106, 106 ... on the storage base 103, the pulled out container 93 can be automatically sent to the front of the machine body. The work efficiency is improved and the operator does not need to manually move the storage container 93, thereby improving the work efficiency.

  Further, by providing the U-shaped support frame 113 constituting the waste storage support table 115 on the left and right sides of the rear end portion of the storage table 103, the mounting stays 112, 112 are provided. Therefore, the twist is prevented from occurring, and the strength of the support frame 113 is improved.

Hereinafter, another embodiment of the ginseng harvester will be described.
As shown in FIGS. 19 and 20, left and right mounting support plates 129 and 129 are arranged at predetermined intervals in the left-right direction on the front side of the front remaining leaf processing frame 72a, specifically, left and right square pipes constituting the rotating frame 20. They are arranged with approximately the same interval as the left and right intervals of 20a, 20a or a slightly wider interval. A transport assist frame 130 that is long in the front-rear direction is provided on the upper side of the left and right attachment support plates 129 and 129 and above the elevating cylinder 23 with a space in the left-right direction. , 130, a driven assist roller 131 is rotatably disposed between the left and right rear end portions.

Further, a drive assist roller 132 is rotatably mounted between the left and right front end portions of the left and right transport assist frames 130, 130, and the transport assist is configured by an elastic body between the drive assist roller 132 and the driven assist roller 131. The belt 133 is wound endlessly, receives the mud falling from the carrot being transported by the pulling and transporting device 24, transports it to the remaining leaf processing section E, and receives the lower side of the long carrot in the vertical direction. A conveyance assist conveyor 134 that prevents contact with the belt 23 is configured.

  A tail cutting device 35 is disposed on the front side of the conveyance assist conveyor 134, and the front end portion of the conveyance assist conveyor 134 is positioned above the rear side of the tail cutting device 35 in the front-rear direction. The posture is inclined backward from the start side toward the end side. In addition, the conveyance end portion of the conveyance assist conveyor 134 is positioned above the remaining leaf processing conveyor 76.

  Then, one end of the shaft of the drive assist roller 132 is penetrated from the conveyance assist frame 130 on the inner side (left side) of the machine body, and an input pulley 135 is pivotally attached to the end of the shaft, and tail cutting of the tail cutting device 35 is performed. An output pulley 136 is attached to the end of the output shaft of a drive motor (not shown) that rotates the blade 35a. Then, the transmission belt 137 is wound endlessly across the output pulley 136 and the input pulley 135 to constitute the driving force transmission mechanism 138 of the assist conveyance conveyor 134.

  The driving force transmission mechanism 138 changes the conveyance speed of the conveyance assist conveyor 134 and the rotation speed of the tail cutting blade 35a by changing the output of the drive motor, and the strength of the tension of the conveyance assist belt 133 of the conveyance assist conveyor 134. This is an effect equivalent to changing the weight of the lowering weight 126 to change the tension of the protective mat 125.

  The driving force transmission mechanism 138 is provided with a cover (not shown) that covers at least the upper side, so that mud and water pouring from carrots are prevented from adhering to the input pulley 135, the output pulley 136, and the transmission belt 137. Durability is improved and cleaning to remove mud and water is not necessary, improving maintenance. Further, the front end portions of the left and right transport assist frames 130 and 130 are supported by a cover case 35 b of the tail cutting device 35.

  With the above configuration, the transfer assist conveyor 134 receives muddy soil and water that pours off from the carrot and is transported toward the rear of the machine body. Occurrence of malfunction is prevented.

  Moreover, since mud and water do not remain on the spot, they are transported to the transport assist conveyor 134 and the remaining leaf processing conveyor 76 and discharged to the outside of the machine, thereby reducing the time and labor required for cleaning to remove the mud and water. Therefore, the labor of the operator is reduced and the maintainability is improved.

  The longitudinal mounting holes 129a are formed in the left and right mounting support plates 129 and 129, and the rotating shaft of the driven assist roller 131 is movably inserted into the left and right elongated holes 129a and 129a. Even if the rotation frame 20 is rotated by extending and retracting the frame 23, the positional relationship between the conveyance assist conveyor 134 and the tail cutting device 35 can be kept substantially the same in accordance with the posture of the rotation frame 20. The carrots whose roots have been removed by the device 35 can be received by the conveyance assist conveyor 134 and conveyed toward the rear of the machine body without being damaged.

  Further, since the front end portions of the left and right conveyance assist frames 130 and 130 are supported by the cover case 35b of the tail cutting device 35, a difference in level between the tail cutting device 35 and the conveyance assist conveyor 134 is unlikely to occur. Since it is hard to be shocked, the carrot is prevented from being damaged.

  Further, by positioning the conveyance end portion of the conveyance assist conveyor 134 above the remaining leaf processing conveyor 76, the stems and leaves are cut above the conveyance assist conveyor 134 or above the remaining leaf processing conveyor 76, and the carrot falls. However, since the carrot can be sent to the remaining leaf processing conveyor 76, it is prevented that the remaining leaf remains in the carrot, the operator does not need to process the remaining leaf manually, and the labor of the worker is reduced. The

  As shown in FIGS. 21 and 22, in the cover case 35 b of the tail cutting device 35, the rear end side of the center cover 35 d forming the tail passage groove 35 c.

  The intervals between the conveying ribs 133a may be the same in the left-right direction and the front-rear direction, or the left-right direction interval may be narrower than the front-rear direction interval. .

  With the above configuration, among the carrots whose roots have been cut by the tail cutting device 35, the carrots that are long in the vertical direction are moved along the center plate 35 d and are then conveyed in contact with the conveyance assist conveyor 134. Since it is possible to prevent the impact of contact due to a drop between 35 and the conveyance assist conveyor 134, the carrot is prevented from being damaged by the impact of contact, and the product value of the carrot is improved.

  Further, an output pulley 136 is provided inside the machine body, that is, below the side cover 35e on the left side of the machine body, and an input pulley 135 is provided between the conveyance assist frame 130 and the drive assist roller 132 inside the machine body to which a belt guide is attached. Since the transmission belt 137 is wound endlessly around the pulley 135 and the output pulley 136, the side cover 35e and the belt guide 137a prevent the mud and water from adhering, so that the driving force is transmitted to the conveyance assist conveyor 134. Is prevented from being hindered by mud and water, improving work efficiency.

  And by forming a plurality of transport ribs 133a on the surface of the transport assist belt 133, the carrot falls down even if the carrots that fall and fall off on the transport assist conveyor 134 that is in a back-up inclined posture. Since the conveyance ribs 133a are prevented, the same carrot does not move on the conveyance assist conveyor 134 many times, and the work efficiency is improved.

  In addition, since the same carrot does not move on the transport assist conveyor 134 many times, the carrot being transported by the transport assist conveyor 134 is prevented from colliding with the carrot falling and falling. This prevents the carrots from being damaged by the impact, and improves the product value of the carrots.

  As shown in FIG. 23, the front end portions of the left and right transport assist frames 130, 130 are attached to the left and right square pipes 20a, 20a, and are configured to move in the front-rear direction by the length of the long holes 129a, 129a. A plurality of left and right slits 133 s are formed in the conveyance assist belt 133 at predetermined intervals in the front-rear direction, and a carrot root in the middle of conveyance enters the outer circumference of the drive assist roller 132 on the conveyance assist belt 133. An arc-shaped cutter plate 139 is disposed along the surface. The cutter plate 139 is formed with adjustment long holes (not shown) on both the left and right sides, and fixing members (not shown) such as bolts are inserted into screw holes (not shown) formed in the left and right transport assist frames 130, 130.

  The electric motor 140 changes the output speed of the transfer assist conveyor 134 and the rotation speed of the tail cutting blade 35a, and changes the tension of the transfer assist belt 133. The same effect as changing the tension of the protective mat 125 by changing the weight of the protective mat 125 can be exhibited.

  With the above configuration, the rear end portion of the cutter plate 139 in a state where the hair root at the lower end portion of the carrot root portion that has entered the slit 133s formed in the conveyance assist belt 133 has entered the shear slit 139s at the conveyance start end portion of the conveyance assist conveyor 134. Since the hair root is sheared by being sandwiched between the conveyance assist belt 133 and the cutter plate 139, a rotating blade that rotates by receiving a driving force becomes unnecessary, so that the number of parts can be reduced and the configuration can be reduced. Be concise.

  In addition, since the carrots that have fallen after the foliage are cut are received by the transport assist conveyor 134 and moved to the remaining amount processing conveyor 76, it is difficult for the remaining leaves to remain in the harvested carrots, and the worker manually handles the remaining leaves. This eliminates the need for removal and reduces the labor of the operator.

  Furthermore, by providing the cutter plate 139 at the conveyance start end of the conveyance assist conveyor 134, the carrot root of the cut carrot falls downward from the left and right spacing portions of the square pipes 20a and 20a at the front side of the machine body relative to the lifting cylinder 23. Therefore, the root of the lift cylinder 23 is prevented from coming into contact with or clogged, and the lift cylinder 23 is prevented from being damaged or malfunctioning.

  Then, the front end portions of the left and right transport assist frames 130, 130 are attached to the left and right square pipes 20a, 20a, and the rear end portions are attached to the left and right support plates 122, 122, whereby the transport assist conveyor 134 is rotated. Therefore, the machine body is less likely to vibrate, the workability is improved, and the operator is less likely to feel discomfort, thereby reducing the labor of the operator.

  As shown in FIGS. 24 and 25, left and right crosspieces 141 are provided on the surface of the conveyance assist belt 133 at predetermined intervals in the front-rear direction, on the conveyance start end side of the conveyance assist conveyor 134, and on the conveyance assist belt 133 and the crosspiece. It is good also as a structure which arrange | positions the shear plate 142 which formed several shear slit 142s ... in the front and upper direction of the body 141 ... bent in the R shape along the circular arc surface of the conveyance start end part of the conveyance assist conveyor 134. FIG.

  In addition, the crosspiece 141 is made of hard rubber so as not to be bent by weight even when it comes into contact with the lower side of the carrot or when the ginseng that has fallen due to the cutting of the foliage is placed on the transport assist conveyor 134. Or it is good to comprise with the synthetic resin which can exhibit an equivalent function. Further, when the plurality of shear slits 142 s formed in the shear plate 142 are inclined with respect to the transport direction of the transport assist conveyor 134, there is an opportunity for the carrot root of the carrot entering the shear slit 142 s to come into contact with the crosspiece 141. Therefore, since the hair root is reliably removed, the operator does not need to manually remove the hair root.

  According to the above-described configuration, a plurality of horizontally long crosspieces 141 are provided on the conveyance assist belt 133 at predetermined intervals in the front-rear direction, so that the carrots placed on the conveyance assist conveyor 134 can vibrate the airframe. As a result, the crosspiece 141 prevents backflow in the front direction of the machine body, so that the carrots are prevented from staying on the conveyance assist conveyor 134 and can smoothly return to the conveyance path, so that the work efficiency is improved.

  In addition, the carrot staying on the conveyance assist conveyor 134 can be prevented from colliding with the carrot that has fallen due to the cutting of the foliage, and can be prevented from being damaged by the impact of the contact, so the commercial value of the carrot is maintained.

  Further, by providing the shearing plate 142 at the transport start end of the transport assist conveyor 134, the carrot root of the cut ginseng falls downward from the left and right spacing portions of the square pipes 20a and 20a at the front side of the machine body relative to the lifting cylinder 23. Therefore, the root of the lift cylinder 23 is prevented from coming into contact with or clogged, and the lift cylinder 23 is prevented from being damaged or malfunctioning.
