  In addition, by providing the left and right collars 124 at a predetermined interval in the left-right direction, a configuration is adopted in which no member that suppresses bending is disposed in the central portion in the left-right direction where carrots frequently contact the protective mat 125. Since the bend allowance when the ginseng contacts the protective mat 125 is sufficiently secured, the protective mat 125 does not bend sufficiently and the resistance does not increase so that the carrot is not damaged, and the product value of the carrot is further increased. improves.

  Then, the front end portion of the protective mat 125 is pulled downward by the pulling weight 126, and the rear side is fixed to the front remaining leaf processing frame 72a by the fixing member 125a, so that the upper side of the protective mat 125 has an arc-shaped bent portion W. Therefore, the impact when the carrot contacts the protective mat 125 is easily absorbed, and the carrot is not easily damaged.

  Furthermore, by providing the protective device 127 having the protective mat 125 at a position immediately after the rear portion of the tail cutting device 35, the lower end portion of the carrots ejected by the tail cutting device 35 can be received by the protective mat 125. Is prevented from swaying and coming into contact with surrounding components, and the product value of carrots is improved.

  In addition to this, since the carrots shake, the roots are torn off from the foliage and the carrots are prevented from falling on the front side of the machine from the remaining leaf processing part E, so the remaining leaves remaining in the carrots are processed manually. This eliminates the need to pick up the carrots that have fallen out of the machine or out of the transport path, thereby reducing the labor of the operator.

  Further, since the rear hanging portion of the protective mat 125 is fixed to the front remaining leaf processing frame 72a by the fixing member 125a, the rear end portion side of the protective mat 125 comes into contact with the elevating cylinder 23, and the elevating cylinder 23 is expanded and contracted. Since the hindrance can be prevented, the drawing work height of the drawing / conveying device 24 is accurately adjusted, so that the work efficiency is improved.

  Furthermore, since the rear side of the protective mat 125 covers the upper portion of the elevating cylinder 23 in the vertical direction, it is possible to reliably prevent foreign matters from falling into the elevating cylinder 23, and the elevating cylinder 23 is damaged. And the occurrence of malfunctions are prevented, durability is improved and workability is improved.

As a result, it is possible to adjust the position by moving the aligned sprockets 45, 45 in the left-right direction. Therefore, when not working and when the foliage is not passing or when the foliage with a small diameter passes, the alignment is performed. 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, the operator can adjust the left and right conveyance auxiliary rollers 128 and 128. 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.

  In addition, a lattice-shaped cradle 77 for receiving a crop that has fallen to the front side of the machine body from the foliage cutting device 61 is provided at the start side of the remaining leaf processing conveyor 76 and the front side of the machine body in a downwardly inclined posture, A scooping conveyance drive roller 78 is provided on the inner side of the machine body from the cradle 77, and a scooping conveyance driven roller 79 is provided on the left and right other side portions.

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.

F is configured.

  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.

Next, the accommodating part G is demonstrated.

Then, the assist roller 131 is attached to the upper end portion of the stopper arm 130 so as to be rotatable in the clockwise direction when viewed from the back. A one-way clutch or the like is used for regulating the rotational direction. When the stopper arm 130 is rotated to the left and right other sides of the machine body, the conveyance assist roller 131 is located on the left and right other side (the left side of the machine body) than the left and right other side edges (the left side of the machine body) of the mounting support frame 90. And it mounts | wears with the stopper arm 130 so that it may be located in the left-right one side (machine body right side) rather than the left-right one side edge part (machine body right side edge part) of the container container 103 mentioned later.

  In addition to this, an attachment plate 90a is extended at the lower part of the left and right sides of the mounting support frame 90, and an operation pedal 132 that is operated by the operator's foot is provided at step 99 to be described later. The attachment plate 90 a and the lower end of the stopper arm 130 are connected by a tilting wire 133.

  When the operation pedal 132 is stepped on, the tilting wire 133 is pulled, and the stopper arm 130 to which the tilting wire 133 is connected is also pulled to the left and right sides of the machine body. It becomes the structure which moves toward the left and right other sides of the body. At this time, when the upper end portion of the assist roller 131 is positioned slightly above the upper end portion of the storage container carrier 103, the movement of the storage container 93 is assisted. In addition, when the operator removes his / her foot from the operation pedal 132 and the tension wire 133 loses tension, the stopper arm 130 rotates to the left and right sides of the machine body and returns to the position where the movement of the container 93 is restricted again. To do.

  In addition, as shown in FIG. 19, a fulcrum part 90b is formed at a position closer to the storage part 103 than the central part in the left-right direction of the mounting support frame 90, and the fulcrum part 90b is formed by a spring 134a. It is good also as a structure attached to the mounting base frame 134 urged | biased by the up-down direction so that rotation is possible in the left-right direction. The fulcrum portion 90b is provided with a biasing member (not shown) such as a torque spring, and when there is no heavy object on the mounting support frame 90, the mounting support frame 90 is biased to the left and right sides of the body. Thus, the structure is held in a substantially horizontal state.

  In the above configuration, when a heavy object such as the storage container 93 is placed on the placement support frame 90, the placement support frame 124 is lowered and inclined to the left and right other sides of the machine body along the fulcrum portion 90b. As a result, it becomes easier to move the storage container 93 from the storage container mounting table 97 to the storage container carrier 103, so that the work efficiency is improved.

  In addition, one end portion of the damper 96 that expands and contracts according to the weight of the storage container 93 is provided on the mounting support frame 90, and the other end portion of the damper 96 is attached to the rotating frame 20. The damper 96 has a small amount of carrot introduced into the storage container 93, and when the weight is light, the damper 96 is shortened to shorten and rotate the mounting support frame 90 upward. The support frame 90 is configured to rotate downward.

The storage container mounting table 97 is configured as described above.
Then, a preliminary storage container mounting table 98 for mounting an empty storage container 93 or the like on the rear part of the storage support frame 90 that constitutes the storage container mounting table 97 can be rotated back and forth, and the storage container mounting table 97 can be rotated in the field. When it is in a substantially horizontal posture, it is attached so as to be in a back-up tilt posture. When the storage container 93 is removed from the storage container mounting table 97, the preliminary storage container mounting table 98 is disposed at an angle at which the empty storage container 93 loaded is slid down on the storage container mounting table 97. At this time, the upper part of the storage container 93 that stores the carrots serves as a stopper for the empty storage container 93.

  Further, a step 99 for placing an auxiliary worker's foot on the left and right sides of the sorting and conveying conveyor 87 is provided, and a pair of front and rear mounting arms 100 and 100 are provided below the step 99. Rotating stays 101, 101 having an H shape in plan view are attached to the left and right other ends of the machine body. Further, a hollow support frame 102, 102 is provided on the rotation stays 101, 101 so as to be rotatable up and down, and a storage container carrier 103 for mounting a plurality of storage containers 93 storing carrots on the support frames 102, 102. Is placed with the long side facing in the longitudinal direction of the aircraft. The storage container carrier 103 is configured to be able to be rotated to the side of the machine body frame 1 when not in operation or the like, and to have a configuration capable of reducing a space when stored in a warehouse or the like.

  In addition, the left and right other side ends of the machine body in step 99 have substantially the same phase as the left and right other side edges of the mounting support frame 90, and the rear end part of the container carrier 103 is substantially the same as the rear end part of the mounting support frame 90. Same phase.

  Further, when the storage container carrier 103 is rotated to the body frame 1 side with the attachment arms 100, 100 of the step 99 as the rotation stays 101, 101, the step 99 is rotated to the storage container carrier 103 side. It is good also as a structure.

  According to the above configuration, when the container carrier 103 is rotated upward, the step 99 is also rotated upward to be in an inclined posture, so that dirt such as mud and leaf dust that has fallen from the sorting and conveying conveyor 87 and the operator's shoes is obtained. Since an object 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 and 104 are provided at the front portion of the storage container carrier 103, and a pair of left and right driven pulleys 105 and 105 are provided at the rear portion of the storage container carrier 103, and the drive pulleys 104 and 104 and the driven pulley 105 are provided. , 105, a plurality of conveying rollers 106, 106... Are rotatably provided. 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 transport rollers 106, 106... And the transport belts 107, 107: 107, 107 are positioned above the upper end surface of the storage container carrier 103, the storage container 93 comes into contact with the upper surface of the storage container carrier 103. Since it is prevented from being conveyed, work efficiency improves.

By providing a drive motor 108 for driving and rotating the drive pulleys 104 and 104 at the front end of the container carrier 103, a container container transport device 109 is configured.
Further, as shown in FIG. 18, a base frame 135 biased upward by a spring 135a is provided on the container carrier 103 and between the left and right of the left and right transport belts 107, 107: 107, 107. A roller frame 136 on which a plurality of auxiliary conveyance rollers 137... The roller frame 136 and the base frame 135 form a fulcrum part 136b at a position closer to the mounting support frame 90 than the central part in the left-right direction, and when the container 93 is mounted on the roller frame 136, the left and right sides of the machine body When the container 93 is not provided, the roller frame 136 is attached to the left and right sides of the machine body by a biasing member (not shown) such as a torque spring provided on the fulcrum part 136b. It is set as the structure hold | maintained in a substantially horizontal state. The spring 135a has a biasing force such that when the container 93 containing carrots is placed on the roller frame 136, the spring 135a contracts and lowers the base frame 135. The auxiliary rollers 137 are configured to move downward relative to the left and right conveying belts 107, 107: 107, 107.

  With the above configuration, when the storage container 93 is moved from the storage container mounting table 97 to the storage container carrier 103, the plurality of transport auxiliary rollers 137 attached to the roller frame 136 assist the movement of the storage container 93. The movement of the storage container 93 is prevented from stagnation, the work efficiency is improved, and the operator can move the storage container 93 with a light force, so that the work efficiency is improved.

  Further, when the storage container 93 is placed beyond the support portion 136b, the roller frame 136 is inclined toward the left and right sides of the machine body, so that the storage container 93 is moved to the storage container carrier 103 with a lighter force. Therefore, the labor of the worker is further reduced and the work efficiency is improved.

  Further, when the container 93 is placed in the left-right direction of the roller frame 136, the spring 135a contracts and the base frame 135 is lowered, and the upper portion of the conveyance auxiliary roller 137 is moved to the left and right conveyance belts 107, 107. Since the storage container 93 can be reliably transported toward the front side of the machine body by the left and right 107, 107: 107, 107 by being configured to be lower than 107: 107, from the storage container mounting table 97 The storage container 93 moved to the storage container carrier 103 does not stagnate, and the work efficiency is improved.

  2, the drive motor 108 is driven for a predetermined time when the storage container 93 comes into contact with the position where the storage container 93 is received from the storage container mounting table 97 on the left and right side walls of the body of the storage container carrier 103. When the placement 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 conveyed by the storage container transport device 109 comes into contact with the wall surface of the front end portion of the storage container carrier 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 to be operated, it becomes automatically known that the storage container 93 is fully loaded in the storage container carrier 103 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 portion of the container carrier 103, and the ends of the mounting stays 112, 112 protruding rearward are flattened with band steel. A support frame 113 formed in a U-shape is fixed by a fixing pin 113a. Then, the two support pipes 114, 114 are arranged in an X shape between the left and right sides of the support frame 113, and the waste that collects unacceptable carrots (growing defects, abnormal shapes, wounds, etc.) as a product is collected. A waste container support table 115 on which a waste container 93t for collection is arranged is configured.

  2, 21, 22, 25, and 20, the two support pipes 114 and 114 are subjected to a crushing process in which a central portion in the longitudinal direction has a concave shape, and are overlapped intersection points. Since the waste container 93t can be placed in a stable state, the waste container 93t can be prevented from slipping down due to the shaking of the fuselage, and the dropped waste container 93t and the stored carrot This eliminates the need for picking up etc. and improves work efficiency.

The fixing pin 113 a contacts the lower part of the lowermost waste container 93 t and prevents the waste container 93 t from moving to the storage container carrier 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.

The waste container support 115 may be placed with an empty container or a container 93 containing 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 the transfer roller 92 prevents the container from moving to the storage container carrier 103 without permission, the carrot is stored as much as possible and then moved to the storage container carrier 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 container carrier 103, the rotation shaft 91c is provided. Therefore, the load when the operator pulls out the storage container 93 is reduced, and the storage container 93 full of 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. It is possible to prevent the bottom portion of the container from getting into the gap and being caught, so that the container 93 can be moved smoothly to the container container 103, and the work efficiency can be improved.

  Further, by providing the rotating shaft 91a with the brake body 94 for adjusting the rotation speed and the adjustment knob 95, the farm field is stable, and the storage container 93 moves freely from the storage container mounting table 97 toward the storage container carrier 103. When there is little to do, the restriction force of the rotating shaft 91a can be weakened to facilitate rotation, so that the worker can pull out the storage container 93 with a smaller force, thereby reducing the labor of the worker.

  On the other hand, when the storage container 93 tends to move freely from the storage container mounting base 97 toward the storage container carrier 103, such as when the field is often uneven and the machine body is inclined frequently, the regulating force of the rotating shaft 91a is reduced. Since it can be strengthened to make it difficult to rotate, the container 93 is restricted from moving by the transport roller 92 attached to the rotating shaft 91a even when the machine body is inclined, and is prevented from moving to the container carrier 103 without permission. Therefore, the carrot is prevented from being damaged by being dropped on the machine body or the field, the product value of the crop is improved, and it is not necessary to collect the carrot that has been dropped, and the labor of the worker is reduced.

  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.

  A stopper arm 130 for receiving the lower part of the left and right other side ends of the storage container 93 is provided at the left and right other side ends of the mounting support frame 90 so as to be rotatable in the left and right directions. Is more reliably prevented from moving to the container carrier 103, so that the carrot can be prevented from falling and being damaged by the machine body or the field to improve the commercial value of the crop, and it is necessary to collect the fallen carrot. The labor of the operator is reduced.

  Further, since the assist roller 131 is rotatably provided at the upper end portion of the stopper arm 130, the contact resistance applied to the storage container 93 is reduced, so that the storage container 93 can be prevented from being damaged, and the stored carrot Spilling out is prevented.

  Further, when the stopper arm 130 is rotated to the left and right other sides of the machine body, the assist roller 131 is positioned at the space between the storage container mounting table 97 and the storage container carrier 103, so that the storage container is interposed via the assist roller 131. Since 93 can be taken over smoothly, work efficiency improves.

  In addition, since the placement support frame 90 is arranged in a posture that is inclined downward from the left and right sides of the machine body toward the left and right sides, when the stopper arm 130 is moved to the left and right sides, the loaded storage container 93 is placed and supported. Since it slides on the frame 90 and moves to the container carrier 103, the operator does not need to move the container 93, and the labor of the operator is greatly reduced.

  Since the operation pedal 132 for rotating the stopper arm 130 is provided, the operator does not need to directly operate the stopper arm 130, so that the work efficiency is improved. In particular, since the operation pedal 132 is provided at step 99, which is the work position of the worker who sorts the carrots being transported by the sorting and conveying conveyor 87, the worker moves the container 93 while performing the carrot sorting operation. As a result, work efficiency is greatly improved.

  In addition, since the loading sensor 118 is provided on the mounting support frame 90, when the storage container 93 in which carrots are stored in a full capacity is moved to the storage container carrier 103 and is replaced with an empty storage container 93, automatically. Since the driving of the sorting and conveying conveyor 87 can be stopped, the ginseng is prevented from falling when the container 93 is exchanged, and the operator does not need to collect the ginseng that has fallen on the farm field, thereby reducing labor. The

Further, when the container 93 is replaced, the sorting / conveying motor 87m need not be turned on / off, so that the operability and work efficiency are improved.
By providing the loading sensor 118 at the left and right side ends of the mounting support frame 90, the sorting and conveying motor 87m can be stopped immediately after the storage container 93 starts to move toward the storage container carrier 103. As a result, the carrots transported on the left and right sides of the sorting and conveying conveyor 87 are prevented from falling out of the storage container 93, so that the work of picking up the dropped carrots is not required, and the work efficiency is improved. The carrot is not damaged by the impact of the carrot, and the product value of the carrot is maintained.

  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.
Since the container container 103 is provided with the conveyor belts 107, 107: 107, 107 and a plurality of conveyor rollers 106, 106, the extracted 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.

  Furthermore, the support frame 113 having a U-shape in plan view that constitutes the waste storage support table 115 is provided on the mounting stays 112 and 112 that are mounted on the left and right sides of the rear end portion of the storage container carrier 103, whereby the mounting stay 112, Since the phase of 112 does not substantially change, the occurrence of twisting is prevented, and the strength of the support frame 113 is improved.

Hereinafter, another embodiment of the ginseng harvester will be described.
As shown in FIG. 21, a stacking sensor 118 is provided at one end on the left and right sides of the mounting support frame 90, a third rotating shaft 91c is provided on the other left and right sides, and the left and right between the loading sensor 118 and the third rotating shaft 91c. The second rotating shaft 91b is provided near the center in the left-right direction of the mounting support frame 90. Then, first divided conveying rollers 92v and 92w obtained by dividing the conveying roller 92 in the front-rear direction are rotatably mounted on the second rotating shaft 91b, and are mounted on the rear portion of the second rotating shaft 91b and the second rotating shaft 91b. A brake body 94 such as a disc spring is pivotally mounted between the mounting support frame 90 and an adjustment knob 95 for adjusting the resistance of the brake body 94 is attached to the rear end portion of the second rotating shaft 91b.

  Further, a spring 138 is provided at the front end portion of the second rotation shaft 91b, and a winding wire 139 is disposed between the spring 138 and the rotation fulcrum of the mounting support frame 90. The mainspring 138 is wound around the winding wire 139 when the mounting support frame 90 is lowered due to the contraction of the damper 96, and the mainspring 138 starts to rotate when the damper 96 is fully contracted and the mounting support frame 90 is lowest. . The mainspring 138 is rotated in the clockwise direction when viewed from the back, and the first divided transport rollers 92v and 92w pivotally attached to the second rotation shaft 91b automatically move the container 93 to the container carrier 103. And

  Further, a lock mechanism 140 constituted by a solenoid or the like having a lock body 140a for stopping the rotation of the mainspring 138 is provided at the front portion of the mainspring 138, and the lock mechanism 140 is connected to the load sensor 118 by a cable (not shown). . When the load sensor 118 detects the movement of the storage container 93, the lock mechanism 140 sets the lock mechanism to the “released” state, retracts the lock body 140 a to allow the spring 138 to rotate, and the load sensor 118 detects the storage container 93. Is detected, the lock body 40a is configured to restrict the rotation of the mainspring 138. Note that the lock mechanism 140 may automatically be in the “hold” state when the damper 96 extends and the mounting support frame 90 rotates upward and the winding wire 139 starts to wind the mainspring 138.

  In addition, the second divided conveying roller 91u is mounted only on the front side of the body of the third rotating shaft 91c so as to be rotatable and not moved in the front-rear direction along the third rotating shaft 91c. The third and fourth divided conveying rollers 92 s and 92 t are placed between the left and right conveying belts 107 and 107: 107 and 107 on the rear end of the container carrier 103, that is, on the other left and right sides of the mounting support frame 90. And provided below. The third divided conveying roller 92s is provided on the side of the left and right conveying belts 107 and 107, and the fourth divided conveying roller 92t is provided on the side of the left and right other conveying belts 107 and 107.

  Further, the fourth divided conveying roller 92t is provided on a substantially straight line on the left and right sides of the second divided conveying roller 92u, and the third divided conveying roller 92s is located behind the machine body than the second divided conveying roller 92u and the fourth divided conveying roller 92t. Provided on the end side.

  Since the mainspring 138 is wound by the winding wire 139 when the mounting support frame 90 descends, the operator does not need to manually wind the mainspring 138 and the work efficiency is improved.

  In addition, the configuration is such that the conveyance roller 92 (first divided conveyance rollers 92v and 92w) is rotated by the rotation of the mainspring 138 to facilitate the movement of the storage container 93. Since the system can be omitted, the structure of the airframe is simplified and the number of parts is reduced.

  Since the lock mechanism 140 for restricting the rotation of the mainspring 138 is connected to the stacking sensor 118, the mainspring 138 does not rotate unless the storage container 93 is moved. Therefore, the operator stores the carrot in the storage container 93 to the full capacity. Then, the transport roller 92 can be rotated, and the work efficiency is improved. In addition, since the frequency of loading and unloading the storage container 93 decreases, the labor of the operator is reduced.

  Furthermore, since the second, third, and fourth divided transport rollers 92s, 92t, and 92u are arranged in a staggered manner in plan view, the transport accuracy of the storage container 93 can be maintained even if the number of parts is reduced. The work efficiency can be improved and the cost can be reduced.

  Note that the left and right sides of the first divided conveying rollers 92v and 92w and the second divided conveying roller 92s, the right and left sides of the second divided conveying roller 92s and the third divided conveying roller 92t, and the third divided conveying roller 92t and the fourth divided conveying roller. When the distance between the left and right of the rollers 92u is a distance at which the container 93 being conveyed is stacked on the two divided conveying rollers, the container 93 is not dropped onto the field, and the work efficiency is improved.

  As shown in FIGS. 22 to 24, a takeover assist arm 141 having a U-shape in a plan view and an L-shape in a back view is provided on the container carrier 103 and between the left and right of the left and right transport belts 107, 107: 107, 107. A takeover assist roller 142 is rotatably mounted between the front and rear ends of the left and right side end portions of the takeover assist arm 141. Further, the left and right other side end portions of the takeover assist arm 141 are set as left and right rotation fulcrums.

  In step 99, the second operation pedal 143 is provided, and the connecting cable 144 is routed across the lower end of the takeover operation pedal 143 and the takeover assist arm 142. At this time, the distance between the center point of the transport roller 92 that is pivotally attached to the third rotating shaft 91c and the center point of the takeover assist roller 142 is configured to be shorter than the lateral width of the container 93. Further, when the takeover assist arm 141 is turned upward, the upper part of the takeover assist roller 142 is positioned above the upper ends of the left and right transport belts 107, 107: 107, 107, and the takeover assist arm 141 is turned downward. The upper part of the transfer assist roller 142 is positioned below the upper ends of the left and right transport belts 107, 107: 107, 107.

This structure is also provided on the front side of the body of the container carrier 103 and on the left and right sides of the front carrier 150 as shown in FIGS.
