Since the work of moving the carrot is not necessary, the work efficiency is improved and the labor of the worker is reduced.

  Further, if mats (not shown) made of a material having elasticity and a low coefficient of friction are laid on the discharge shooter 43 and the feedback shooter 44, the carrots are cracked or crushed due to an impact generated at the time of dropping. Therefore, the product value of the carrot is improved, and the carrot does not roll off from the discharge shooter 43 or the feedback shooter 44, so that the operator does not need to move the carrot to the hopper 2, so that the work efficiency is improved. As well as improving, the labor of the operator is reduced.

  Then, one ginseng is guided to be discharged from the conveyance end of the alignment conveyance conveyor 42 on both the left and right sides of the alignment conveyance conveyor 42 and at a position closer to the front side than the acceleration driven pulley 38 and the left and right alignment driven pulleys 39, 39. At the same time, when a plurality of carrots are in contact with each other at the same time, the left and right guide plates 45, 45 are guided in plan view so that the excess carrots are guided to the discharge shooter 43 and the longitudinal direction of the carrots is oriented in the transport direction of the alignment transport conveyor 42. Thus, the left and right widths become wider toward the upper side of the conveyance, and the left and right sides on the base side are arranged in a posture that is substantially the same as the left and right width of the alignment conveyance conveyor 42. If the left and right guide plates 45, 45 are made of a soft elastic material such as vinyl chloride, the carrots are not damaged even if they come into contact with the carrots, so that the product value of the carrots is improved.

  With the above configuration, when the carrots are transported by the alignment transport conveyor 42, even if a plurality of carrots are overlapped, the overlapped carrots are guided to the falling shooter 43 at the latest when they contact the left and right guide plates 45, 45. Since it can be returned to the hopper 2 of the storage part A, the carrots are sent one by one to the sorting and conveying part E, which will be described later, and the occurrence of missorting in which a plurality of carrots are detected simultaneously is prevented.

  Moreover, when the conveyance posture of the carrots is corrected to a posture that is oriented in the longitudinal direction with respect to the conveyance direction of the alignment conveyance conveyor 42, the distance between the front and rear of the carrots when being conveyed by the sorting conveyance unit E is a substantially constant distance. As a result, the sorting timing becomes substantially equal, and a plurality of carrots are not moved to the storage container at the same time, so that the sorting accuracy is further improved.

  Since the upper surfaces of the left and right alignment conveyance belts 41 and 41 are positioned above the upper surface of the acceleration conveyance belt 40, the carrot can be held and conveyed by the left and right alignment conveyance belts 41 and 41. Therefore, since the carrots placed on the aligning and conveying conveyor 42 in an appropriate posture are not easily dropped from the aligning and conveying conveyor 42, the interval at which the carrots are taken over one by one on the sorting and conveying conveyor 70 is not too wide, and the work efficiency is improved. .

  Furthermore, the upper end portions of the left and right protrusions 38v and 38v formed on the left and right side portions of the acceleration driven pulley 38 are positioned higher than the upper ends of the left and right alignment transport belts 41 and 41, so that the alignment transport conveyor 42 When the carrot is handed over from the transport end to the transport start end of the sorting transport conveyor 70, the left and right protrusions 38v, 38v push the carrot toward the sorting transport conveyor 70, so that the carrots that have been handed over to the sorting transport conveyor 70 Since sufficient intervals can be taken, multiple carrots may be mistakenly detected as a single carrot, and the next carrot may be involved in the operation of moving the preceding carrot to the collection unit, resulting in misselection. It is prevented, and carrots are collected by size, improving the sorting accuracy.

Further, it is not necessary for the operator to manually re-sort the misselected carrots, thereby reducing the labor of the worker and the work time.
Further, since the acceleration drive motor 26 and the alignment drive motor 27 are configured to be capable of changing the rotation speed by an inverter, the transfer speeds of the acceleration transfer belt 40 and the left and right alignment transfer belts 41 and 41 can be changed, thereby selecting. Since the transport speed of the carrots of the alignment transport conveyor 42 can be adjusted according to the conditions such as the number of carrots, kind, size, etc., the interval between the carrots is too wide and the time interval for performing the sorting operation becomes long. And the efficiency of the sorting operation is improved.

  In addition, the distance between carrots is too narrow, and multiple carrots are mistakenly detected as one, and the next carrot is involved in the operation of moving the preceding carrots to the collection unit, preventing misselection. The sorting accuracy is improved.

  The peripheral speed of the accelerating transport belt 40 is slower than the peripheral speed of the sorting and transporting conveyor 70 at the fastest, so that the carrot transferred from the sorting and transporting conveyor 35 to the sorting and transporting conveyor 70 can be transported at a higher speed. Therefore, the gap between the carrots is surely widened to prevent erroneous sorting and improve the sorting accuracy.

  Further, by providing the collars 3c and 36c between the acceleration drive pulley 35 and the left and right alignment drive pulleys 36 and 36, respectively, even if the rotation speed of the acceleration drive motor 26 and the alignment drive motor 27 is changed, the acceleration drive pulley 35 and the left and right alignment driving pulleys 36 and 36 can rotate independently of each other. Therefore, rotation of the acceleration conveyance belt 40 and the left and right alignment conveyance belts 41 and 41 at a set peripheral speed allows the carrots to be aligned. The posture of the carrot that is efficiently performed and is taken over by the sorting and conveying conveyor 70 is stabilized, and the sorting accuracy is improved.

  Further, the output shaft 30 provided with the output gear 33 for transmitting the driving force to the acceleration drive pulley 35 is provided with a tension mechanism 32 for urging the output shaft 30 upward, so that the acceleration drive pulley 35 and the left and right alignment are aligned. When the drive pulleys 36, 36 bite carrot fragments and ginseng leaves, and overload, the tension mechanism 32 retracts the output shaft 30 and the output gear 33 downward. Damage to the drive unit is prevented.

  In the configuration described above, there is nothing that restricts the movement of the carrots to the discharge chute 43 on the left and right sides of the alignment conveyer 42. It may fall as soon as it approaches. If this is a plurality of carrots, there is no particular problem. However, when one carrot is being transported, there will be a problem that the time for sorting becomes empty and the work time slightly increases. This problem is particularly likely to occur when ginseng harvested in early summer, which tends to grow and whose average size tends to be large, or when carrots of varieties that tend to grow are selected.

  In order to reduce the occurrence of this problem, as shown in FIGS. 2 to 4, the fixed shutter 46 is arranged on either the left or right side of the aligned transport conveyor 42, in this example, on the left side with respect to the upper transport side of the aligned transport conveyor 42. Is provided over the same range as the front and rear lengths of the discharge shooter 43, and on the opposite side to the side where the fixed shutter 46 is provided, in this example, the slide shutter is slidable in the front and rear direction over a predetermined range. 47 is provided.

  The fixed shutter 46 is disposed so as to protrude by about 20 mm in the vertical direction, and can contact a third to a quarter of the area from the lower side when a large carrot passes. This numerical value of about 20 mm is based on 60 to 80 mm, which is the average diameter of large (2L to 3L) carrots. A plurality of mounting holes 46a are formed at intervals from the front end portion of the fixed shutter 46 on the upper transport side to the vicinity of the front and rear center portion in the transport direction, and a plurality of overlapping ginsengs are formed in the mounting holes 46a. The contact protrusions 482... That are brought into contact with each other and are pushed out to the right side of the alignment conveyer 42 to break the overlap are configured to be mountable. The contact protrusion 48 is shown in FIG.

  The plurality of mounting holes 46a are formed so that the front and rear intervals between the mounting holes 46a are narrow on the upper conveyance side, and the front and rear intervals between the mounting holes 46a are formed in the vicinity of the front and rear center portion in the conveyance direction. Are not formed with mounting holes 46a.

  As shown in FIG. 3, the contact protrusion 48 has an operating body 48a for adjusting the amount of insertion from the outer side of the fixed shutter 46, that is, the alignment side wall 24 side, and a protrusion amount to the alignment conveyor 42. It is constituted by a contact body 48b formed by connecting a plurality of spherical adjustment bodies 48c... That can adjust the amount of adjustment, for example, 1 to 2 mm per unit. Accordingly, when the operating body 48a is pushed and pulled, the position of the contact body 48b can be held by the valley formed between the adjusting bodies 48a, and the protruding amount of the contact protrusion 48 can be easily adjusted. Can do. When the adjusting body 48c is configured to be attached to an elastic core (not shown), even if it is made of a hard material such as metal, it can be bent when it comes into contact with the carrot, and the carrot is not damaged. .

The upper part of the fixed shutter 46 has an R shape, for example, by bending to prevent it from being damaged even if the overlapped carrots come into contact.
The slide shutter 47 is slidably provided on the left side of the alignment transport conveyor 42 in the transport direction, and the carrot fall path from the alignment transport conveyor 42 to the discharge shooter 43 as it moves toward the upper transport side. Is opened, and the carrot fall path narrows as it moves toward the lower conveyance side. The slide shutter 47 has a width of 60 to 80 mm, which is substantially the same as the average diameter of large (2 L to 3 L) carrots in the vertical direction, and the slide shutter 47 is arranged on the side of the alignment conveyor 42. From the region located in the direction, the carrots conveyed by one are not dropped, but a plurality of the ginseng conveyed in an overlapping manner are dropped onto the discharge shooter 43 from above the slide shutter 47. Further, the base side of the feedback shooter 44 is disposed on the side where the slide shutter 47 is provided.

  If the upper portion of the slide shutter 47 is formed in an R shape by bending the same as the fixed shutter 46, the carrot falling on the discharge shooter 43 from above the slide shutter 47 can be prevented from being damaged. Product value is maintained.

  The left and right alignment side plates 24 and 24 and the slide shutter 47 are made of stainless steel in order to prevent corrosion due to the water of the carrot adhering to the carrot and the thin skin of the carrot dissolved in the water. To do.

Thereby, the alignment conveyance part C is comprised.
By adopting the above-described configuration, it is possible to narrow a drop port from the alignment conveyance conveyor 48 to the discharge shooter 43 according to the amount of the slide shutter 47 moved to the lower conveyance side, so that carrots protrude from the alignment conveyance conveyor 48. Even if it is transported in a hung state, it is difficult for it to fall onto the discharge shooter 43, and it is prevented that the distance between the front and rear of the carrots on the sorting and conveying conveyor 70 becomes too wide, and the efficiency of the sorting work is improved.

  In particular, when there is a large amount of carrot having a size of L or more, the carrot is often transported in a state of protruding from the alignment transport conveyor 48. Therefore, the carrot that falls to the discharge shooter 43 and returns to the hopper 2 is reduced, and the work efficiency is further increased. Will improve.

  The upper and lower height of the fixed shutter 46 is set to about one third to one fourth of the upper and lower height of the slide shutter 47, so that the upper end portion of the fixed shutter 46 among the plurality of carrots conveyed in an overlapping manner. Those located above the upper side of the fixed shutter 46 can fall onto the discharge shooter 43, so that the conveyance of carrots on the alignment conveyance conveyor 48 is stagnant, and a plurality of separation conveyors 70 are arranged on the selection conveyance conveyor 70. The carrots are prevented from being transported at the same time, the work efficiency is improved, and the wrong sorting of the carrots is prevented, so that the sorting accuracy is improved.

  Further, by providing the contact projections 48 ... in the mounting holes 46a ... of the fixed shutter 46, the carrots that have contacted the contact projections 48 ... can be pushed toward the slide shutter 47, so that a plurality of overlapping carrots can be formed. The posture can be lost and excess carrots can be dropped onto the discharge shooter 43, so that a plurality of carrots are not simultaneously transferred to the sorting and conveying conveyor 70, and the sorting accuracy is improved.

  In addition, since the protrusion amount of the contact protrusions 48 on the alignment transport conveyor 48 can be adjusted, the protrusion amount can be adjusted in accordance with the approximate size of the carrot performing the sorting operation. 48... Does not reach the carrots and a plurality of carrots are thrown into the sorting and conveying conveyor 70 to prevent erroneous sorting, and the sorting accuracy is improved.

  In addition, since the contact protrusions 48 can prevent the carrots from being moved to the slide shutter 47 side and the carrots transported by only one are dropped onto the discharge shooter 43, the front and rear intervals between the carrots are free. Overpassing is prevented, and the efficiency of the sorting operation is improved.

  The mounting holes 46a for attaching the contact protrusions 48 are formed with a short front-rear interval on the upper transport side, and a wider front-rear interval near the front-rear center in the transport direction than the front-rear interval on the upper transport side. By forming a plurality of carrots, the carrots are continuously brought into contact with the contact protrusions 48 at the upper transfer position of the aligned transfer conveyor 48 where a plurality of carrots are transported in an overlapping manner, thereby breaking the carrot overlap. Therefore, it is possible to prevent a plurality of carrots from overlapping and moving on the lower conveyance side of the alignment conveyance conveyor 48, and to improve the sorting accuracy.

  In addition, in the vicinity of the front and rear center part in the transport direction, by reducing the frequency with which the carrots contact the contact protrusions 48, it becomes difficult for the carrots transported by only one to fall onto the discharge shooter 43, so Return to the hopper 2 is prevented, and the efficiency of the sorting operation is improved.

The storage unit A, the draw-up conveyance unit B, and the alignment conveyance unit C constitute a transfer device D that conveys carrots backward.
Next, the sorting and conveying unit E will be described.

  As shown in FIGS. 8 to 14, a sorting frame 55 is arranged behind the aligning and conveying unit C, and a drive motor 56 having an output sprocket 57 attached to the output shaft at the rear lower part of the sorting frame 55 and on the left and right sides is installed. A motor cover 58 is provided on the drive motor 56. An input sprocket 59 is attached to the left and right ends of the countershaft 60 having a length over the left and right width of the sorting frame 55 above the drive motor 56, and the input sprocket 59 and the output sprocket 57 are connected to the input sprocket 59 and the output sprocket 57. 1 The transmission chain 61 is wound endlessly.

  A second output sprocket 62 is pivotally mounted on the counter shaft 60, a drive rotary shaft 63 is provided above the second output sprocket 62, and a second input sprocket 64 is rotatably mounted on the drive rotary shaft 63. . Further, the second transmission chain 65 is wound around the second input sprocket 64 and the second output sprocket 62 in an endless manner to constitute a transmission path of the sorting and conveying unit E.

  A drive roller 66 having a V-shaped groove formed on the circumference is provided at the end of the drive rotating shaft 63, and is V-shaped at substantially the same vertical position as the drive roller 66 and on the front side of the selection frame 55. A follower roller 67 having a groove formed on the circumference is rotatably provided. In addition, the left and right conveying belts 68 provided with protrusions 68a that enter the V-shaped grooves on the back surface of the driving roller 66 and the driven roller 67 are wound endlessly.

  Further, as shown in FIG. 12 and FIG. 15, left and right shafts 97 are respectively arranged from the sorting frame 55 toward the center in the left-right direction of the machine body on the non-conveying action side (the lower side of the winding area) of the conveying belt 68. A plurality of divided rollers 98... Having a large diameter portion 99 formed on the shaft 97 are axially attached. The left and right cushion rollers 100 that prevent the divided rollers 98 from moving in the left and right directions are provided on the left and right outer sides of the divided rollers 98 and 98 located at the left and right outer ends. A rotatable tension roller 69 that prevents the conveyor belt 68 from slacking downward without diffusing is formed.

  The large-diameter portion 99 formed on the split roller 98 is configured to have a diameter larger than the diameter of the split roller 98 body, shorter than the left and right width of the split roller 98, and on either the left or right side of the split roller 98. It is configured at the end.

Thereby, the conveyance conveyor 70 which conveys a crop toward the back side from the body front side is comprised.
Since the driving roller 66 and the driven roller 67 are disposed in the winding regions of the outer end portions of the conveyor belt 68, when a heavy object is placed on the conveyor belt 68, the conveyor belt 68 is flexible according to the weight. Can bend.

  In the conventional configuration in which a tension roller that is in contact with the shaft over the same range as the left and right width of the conveyor belt is attached, water adhering to the conveyor belt diffuses due to capillary action, and water moves to the back side of the conveyor belt. Therefore, when the conveyor belt comes into contact with the driven roller, the conveyor belt slips, and the transport posture of the carrot is disturbed, or the transport belt is not pushed down by the weight of the carrot at the weight detection position, and the sorting accuracy is lowered. There was a thing.

  However, in this embodiment, the contact area between the tension roller 69 and the conveyor belt 68 is reduced by making the left and right width of the large diameter portion 99 formed on the split roller 98 shorter than the left and right width of the main body of the split roller 98. Since water is prevented from diffusing due to capillary action, it can prevent the transport belt 68 from slipping and disturbing the transport posture of the carrot, and it can prevent the weight of the carrot from being detected at the weight detection position. Therefore, the carrot sorting accuracy is improved.

  In addition, the left and right cushion rollers 100, 100 that prevent the split roller 98 from moving in the left-right direction are provided on the left and right outer sides of the split roller 98 located at the outer end of the machine body. Since the division roller 98 can be prevented from moving in the left-right direction, the division roller 98 can be prevented from moving water to the back side of the conveyance belt 68, and the conveyance belt 68 can be prevented from slipping.

  15, instead of the tension roller 69 shown in FIG. 15, as shown in FIG. 16, the shaft 97 is provided with a plurality of concave portions 103, and a plurality of convex portions 104 having a diameter larger than that of the concave portion 103 and having a short left and right width. The tension rollers 69 may be configured by rotatably mounting the formed uneven rollers 105 having substantially the same left and right length as the left and right width of the conveyor belt 68.

  In the above configuration, since the left and right width of the uneven roller 105 is substantially the same as the left and right width of the conveying belt 68, the uneven roller 105 can move freely in the left and right direction without the left and right cushion rollers 100, 100. Therefore, it is possible to prevent water from moving to the back side of the conveyor belt 68 and to prevent the conveyor belt 68 from slipping.

  In addition, since the concave portions 103 and the convex portions 104 are integrally formed, the concave and convex roller 105 can be easily attached and detached during maintenance or replacement of parts, so that maintenance is improved.

Further, tension rollers 69 as shown in FIGS. 17A and 17B may be used.
A plurality of groove portions 106a... Are formed on the shaft 97 at substantially equal intervals, and a grooved roller 106 having a length substantially the same as the left and right width of the conveying belt 68 is rotatably mounted, and each groove portion 106a. An annular member 107 such as an O-ring having a diameter larger than 106 is provided to constitute a tension roller 69.

  In the above configuration, since the left and right width of the grooved roller 106 is substantially the same as the left and right width of the conveying belt 68, the grooved roller 106 moves freely in the left and right direction even without the left and right cushion rollers 100, 100. Therefore, it is possible to prevent water from being moved to the back side of the conveyor belt 68 and to prevent the conveyor belt 68 from slipping.

  In addition, since the annular members 107 are provided in the groove portions 106a of the grooved roller 106, the plurality of annular members 107 are in contact with the conveying belt 68, so that the grooved roller 106 is not easily damaged and has improved durability. In addition, since the annular member 107 can be easily detached from the groove 106a of the grooved roller 106, the maintainability is improved.

In the case of using any of the large diameter portion 99, the convex portion 104, and the annular member 107 that are in contact with the conveyance belt 68, the left and right width of the portion that is in contact with the conveyance belt 68 is set to 2 to 3 mm.
If it is less than 2 mm, the contact area with the transport belt 68 becomes too small, the pressure applied at the time of contact becomes too high, and the transport belt 68 may be worn and damaged early. If it is 3 mm or more, the contact area becomes large. This may cause the water to diffuse due to the capillary phenomenon and enter the back side of the sorting belt 68.

Further, the left and right widths of the split roller 98 and the recess 103 and the left and right intervals of the annular members 107 and 107 are set to 25 to 30 mm.
If it is less than 25 mm, the number of members increases too much, the number of man-hours for replacement work increases, the maintainability decreases, and the part cost increases. On the other hand, if the thickness is 30 mm or more, the conveying belt 68 may hang down and come into contact with the dividing roller 98, the recess 103, and the grooved roller 106, and water may be diffused and adhered to the back side of the conveying belt 68.

  As shown in FIGS. 8 to 10 (a), 10 (b), and 10 (c), the carrot discharged from the transfer device D is received at a position above the transfer start end of the transfer conveyor 70 and above the sorting frame 55. A side-view L-shaped attachment frame 72 having a hand-down shooter 71 in a downward descending posture to be moved to the conveyor 70 is detachably provided on the sorting frame 55 by a fixing member such as a bolt and a nut.

  As shown in FIGS. 10 (a), (b), and (c), the takeover shooter 71 has a front-rear length at the center in the left-right direction that is the same length as about one 2S size carrot (about 60-80 mm). Or, it is formed in a short length, and the front and rear widths are increased toward the left and right ends, and the length (about 100 to 150 mm) that can support about 40% to 60% of the total length of 3L size carrots at the left and right ends. ). As a result, the rear side of the takeover shooter 71 is formed in a V shape (C shape) in plan view. In addition, a coating layer 71a is formed of a resin material on the contact surface (front surface) of the takeover shooter 71 with a carrot, and the rear end portion of the coating layer 71a extends rearward about 5 mm behind the rear end portion of the takeover shooter 71. Let it come out.

  As shown in FIGS. 8 to 10A, 10B, and 10C, the conveyor belt 68 is prevented from being loosened and moved on the lower rear side of the takeover shooter 71 and in the winding region of the conveyor belt 68. The left and right front slider plates 72 to be promoted are provided, and cushion plates that prevent the carrots jumping out from the terminal portion of the takeover shooter 71 or the transfer device D to the conveyor belt 68 from bouncing due to the impact of falling are provided on the front slider plate 72. 73 is attached. The front slider plate 72 is coated with a slippery resin material, and the cushion plate 73 is made of an elastic body such as rubber or a soft material such as a gel cushion.

  Further, as shown in FIGS. 9 and 11, a rear slider plate 74 is provided in a winding area on the rear end side of the body of the conveyor belt 68, and the front and rear end portions of the rear slider plate 74 are bent in a downward inclined direction. To form a bent portion. Further, between the front slider plate 72 and the rear slider plate 74, a plurality of weight detection devices 75 for detecting the weight of carrots conveyed by the conveyor 70 and the conveyor belt 68 are prevented from loosening and moved. A plurality of sorting slider plates 76 to be promoted are alternately arranged.

  As shown in FIG. 9 and FIG. 11, a front bent portion 76 a that is inclined forward and downward is formed on the front side of the machine body of the sorting slider plate 76, and the bent surface has an R shape on the rear side of the machine body of the sorting slider plate 76. A rear-side bent portion 76b is formed by bending downward substantially at a right angle. The base side of the front support arm 77a is provided at the front bent portion 76a, the base side of the rear support arm 77b is provided at the rear bent portion 76b, and the end sides of the front support arm 77a and the rear support arm 77b are provided. Are attached to the sorting frame 55, and a plurality of sorting slider plates 76 are fixed.

If the front bent portion 76a is bent so as to have an R shape, the conveying belt 68 is less likely to be caught on the sorting slider plate 76, so that the efficiency of sorting and conveying is improved.
Left and right ribs 82 and 82 (protrusions) that promote the movement of the conveyor belt 68 are provided in the front-rear direction on the left and right upper portions of the front slider plate 72, the rear slider plate 74, and the plurality of sorting slider plates 76 between the front and rear. You may paste over.

  When the left and right ribs 82 and 82 are formed in a saw blade shape in which the convex portion and the concave portion are continuous, the contact density with the conveying belt 68 is reduced and the movement of the conveying belt 68 can be made smoother. In addition, even if water adhering to the conveyor belt 68 enters, it is difficult to slip, so that work efficiency is improved.

  Further, the weight detection device 75 is transported by a link arm 77 that can be turned up and down arranged in the winding region of the transport belt 68, and a transport conveyor 70 provided on the upper end of the link arm 77 and at the inner end of the machine body. A weight detection plate 78 through which carrots pass, a detection sensor 79 that emits a signal that activates a jumping device 84 to be described later when the weight detection plate 78 rotates more than a certain distance, and an inner side provided at the outer end of the body of the link arm 77 A weight 80a is inserted into the adjustment plate 80 for adjusting the weight of the carrot determined by the weight detection device 75, and a balance weight 81 for adjusting the fine detection weight.

As shown in FIG. 10B, the machine body inner end portion of the weight detection plate 78 is bent downward at a right angle to form a right angle portion 78a.
In the present embodiment, five weight detection devices 75 corresponding to 3L, 2L, L, M, and S are provided, and carrots can be sorted into five grades. The grade to be detected can be easily changed by increasing / decreasing the number of weights 81a to be placed in the adjusting plate 80. If the weight to be detected is set to be heavier on the front side of the body and lighter on the rear side of the body, all the weight detection devices 75 need only set the lower limit value for starting detection, and the setting of the detected weight becomes easy.

  Then, as shown in FIG. 12 to FIG. 14, the front and rear direction substantially center of the plurality of sorting slider plates 76 on the left and right outer sides of the sorting frame 55 and from the substantially center portion of the weight detection plate 78 to the rear side of the body. A jumping device 84... Is disposed across the section, hitting the carrot being conveyed by the conveyor belt 68 from the side and sending it out to a recovery shooter 93 to be described later. An intermediate plate 85 that prevents the carrot from moving outside the machine body is fixed between the front and rear of the jumping devices 84... And the front end of the weight detection device 75 in the front row from the front end of the sorting frame 55. The front side wall 86 is fixed and provided, and the rear side wall 87 is fixed and provided from the rear end portion of the weight detection device 75 in the last row to the rear end portion of the sorting frame 55.

  The jumping device 84 includes a jumping plate 88 that can rotate in the left-right direction of the machine body, a solenoid 89 that operates when a signal is received from the detection sensor 79, and a conveyor belt 70 that moves the jumping plate 88 from the outside of the machine body when the solenoid 89 is operated. It is comprised with the extrusion arm 90 pushed out on the conveyance path | route. By attaching an elastic body such as rubber to the striking action surface of the jumping plate 88, carrots are prevented from being damaged by the impact of the striking.

  9 and 13, the plurality of intermediate plates 85 are arranged such that the front end portion is positioned on the outer side of the machine body from the rear end portion. The front end portion of the intermediate plate 85 is fixed to the sorting frame 55 with a fixing member such as a bolt, and when the fixing member is removed, the intermediate plate 85 is configured to be rotatable about the rear end side as a rotation center. The rotatable range may be approximately 30 degrees from the substantially linear position in the front-rear direction (0 degrees).

  Further, as shown in FIGS. 8 and 9, between the left and right sides of the conveyor 70 and from the front end portion of the sorting frame 55 to the substantially central portion in the front-rear direction of the weight detection device 75 in the front row, in front view or rear view. A mountain-shaped separation plate 91 is provided, and a plurality of recovery shooters 93 are provided in the front-rear direction to drop ginseng for each size on the rear side of the separation plate 91 and move it to a storage container 92 such as a container. The collection shooters 93 are connected to each other, and a connecting handle 94 that can be lifted by the operator by holding the collection shooters 93 is disposed above and behind the collection shooters 93. And the guide curtain 95 which receives the carrot sent out from the conveyance conveyor 70 of the right-and-left side from the lower part of this connection handle 94 by the jumping apparatus 84 to the inner side of the collection | recovery shooter 93, and drops below is attached.

If the guide curtain 95 is made of a soft member such as rubber or vinyl chloride, it is difficult to be damaged even if it hits the carrot, and the commercial value of the carrot is maintained.
And, as shown in FIG. 8, FIG. 9, FIG. 18 (a) (b) and FIG. 19 (a) (b) (c), it is too large (4L or more) at the transfer terminal portion of the transfer conveyor 70, or A mounting table 96 on which a container 92 such as a box-shaped container or a bag body for collecting non-standard carrots that have not been selected because it is too small (2S or less) is rotatably arranged in the longitudinal direction of the machine body. Then, a support bracket 108 having a “h” shape in a side view is attached between the transfer conveyor 70 and the mounting table 96 and on the rear end side of the sorting frame 55, and is inclined downward toward the rear of the machine body. A scraper plate 109 that scrapes water and impurities by attaching the front end of the support bracket 108 to the transport belt 68 and attaching the scraper plate 109 to the storage container 92 mounted on the mounting table 96 is attached in a rearward downward inclined posture. Thereby, the sorting and conveying unit E is configured.

  The front end of the scraper plate 109, that is, the end in contact with the sorting belt 68 has a blade shape on both the front and back surfaces, so that one side is worn and sufficient water and impurities cannot be scraped off. If the scraper plate 109 is turned upside down, the blade surface that is hardly worn comes into contact with the conveyor belt 68, so that the scraper plate 109 can be used until the opposite surface is completely worn out, thus improving durability. .

  Further, a scraper plate 109 inclined downward toward the rear of the machine body is provided behind the transfer terminal portion of the sorting conveyor 70, and the upper portion of the scraper plate 109 is flat and allows a carrot of 3S or less to pass upward, for example, A storage container 92 in which carrots not to be sorted (minimum carrots of 2S or less) discharged from the sorting conveyor 70 are placed on the placing table 96 by using the plate body and the slat-shaped guide portion 109b with a left-right spacing of less than 10 mm. Therefore, the carrot can be surely discharged outside the machine, and the work efficiency is improved.

  As shown in FIGS. 19A, 19B, and 19C, the scraper plate 109 is formed with long holes 109a that are long in the front-rear direction at equal intervals in the left-right direction. Screw holes 108a with screw grooves are formed in the upper part at the same left and right intervals as the long holes 109a.

  If the gap between the long holes 109a is the same as or slightly longer than the long side of the carrot of 2S or less, even if the scraper plate 109 is attached to the support bracket 108 with a fixing member such as a bolt and nut, the carrot contacts the fixing member. Therefore, it is possible to prevent carrots from being shaved by the impact of contact and reducing the commercial value.

  In addition, carrots that are too small in size 2S or less, carrots that are too large in size 4L or more, malformations such as bifurcating or extreme bending, and carrots that are broken at the time of harvest are generally shipped for processing to be used as materials for juices, frozen foods, etc. Therefore, even if there are some scratches, the product value will not decrease, but if the weight decreases, such as the body being shaved, the value will decrease accordingly, so it is appropriate to prevent damage due to contact with the fixing member etc. it makes sense.

  In order to realize the above significance, if the upper end portion of a fixing member such as a bolt and a nut that fixes the scraper plate 109 to the support bracket 108 does not protrude from the upper end portion of the scraper plate 109 (not shown), 4L or more. Large carrots are less likely to be damaged.

  Further, in order to attach the support bracket 108 to the sorting frame 55, a round hole 108a for attaching a fixing member such as a bolt is formed inside the body of the support bracket 108, and the inclination angle of the support bracket 108 in the horizontal direction is changed outside the body. An arcuate elongated hole 108b is formed.

  In the case of the above configuration, when the upper end position of the long hole 108b is substantially horizontal with the position where the round hole 108a is formed, the support bracket 108 is inclined from the horizontal state with respect to the conveyor 70 from the horizontal state. Adjustment is possible within a range until the conveyor 70 is inclined downward toward the outer side of the machine body, and rotation to an unnecessary range can be restricted.

  On the other hand, when the round hole 108a is formed on the outer side of the machine body and the long hole 108b is formed on the inner side of the machine body, the lower end position of the long hole 108b is set substantially horizontal to the position where the round hole 108a is formed. It is possible to adjust the tilting posture of 108 in the left-right direction from the horizontal state with respect to the transport conveyor 70 to the downward tilting posture with respect to the transport conveyor 70 toward the outer side of the machine body, and rotation to an unnecessary range. Can be regulated.

  Since the front and rear width of the central portion of the takeover shooter 71 is made the shortest, a small carrot of 2S size or less is dropped and moved to the transfer conveyor 70 before staying on the takeover shooter 71. Since the above ginseng merges, it is possible to prevent two or more ginsengs from simultaneously detecting the weight by the weight detection device 75, so the weight detection device 75 misidentifies two small carrots as one large carrot. The jumping device 84 is not operated and the carrot sorting accuracy is improved.

  Furthermore, by making the length of the left and right sides of the takeover shooter 71 long enough to support a 3L size carrot, large ginseng protrudes from the takeover shooter 71 in the left-right direction and falls outside the machine without moving to the conveyor 70. Therefore, it is possible to prevent the carrot from being damaged by the impact of the drop, maintain the product value of the carrot, omit the work of picking up the carrot that has been dropped, and reduce the labor of the worker.

  Further, the coating layer 71a is formed of a resin material on the working surface of the takeover shooter 71, and the rear end of the coating layer 71a protrudes rearward from the rear end of the takeover shooter 71. Since it is possible to prevent the carrot from coming into contact with the sharp edge of the part, the carrot is prevented from being damaged, and the product value of the carrot is improved.

As a result, the takeover shooter 71 can be made of a sturdy material such as a metal plate, so that the takeover shooter 71 can be easily attached and the durability is improved.
Then, by providing the cushion plate 73 on the front slide plate 72 provided below the takeover shooter 71 and in the winding region of the transport belt 68, the impact of the carrot taken over from the transfer device D dropping on the sorting conveyor 70 is received. Since the cushion plate 73 absorbs, the carrot is prevented from being damaged by the impact of dropping, and the commercial value of the carrot is improved.

  Further, when the cushion plate 73 absorbs the impact of carrot falling, the carrot bounces and jumps on the weight detection device 75, and the weight detection device 75 is erroneously detected by the impact of the fall and the jump device 84 is operated. Can be prevented, so that the accuracy of carrot sorting is improved.

  The cushion plate 73 is arranged from the front end portion of the front slider plate 72 to the substantially center position in the front-rear direction, and is not provided on the rear end side close to the weight sorting device 75, so that the cushion plate 73 is as long as the 3L size. Thus, it is possible to prevent weight detection while a part of the heavy carrot is placed on the cushion plate 73, and the sorting accuracy is improved.

  Further, the weight detection is performed by forming the bent portion 74a and the front bent portion 76a that are inclined downward toward the adjacent weight detection device 75 on the front side of the rear slider plate 74 and the front side of the plurality of sorting slider plates 76. When the carrot passes through the weight detection plate 78 of the apparatus 75 while being lowered, the conveyor belt 68 on which the carrot is placed moves along the bent portion 74a and the front bent portion 76a from the rear end portion of the lowered weight detection plate 78. Therefore, it is possible to prevent the conveyance belt 68 from being caught on the front end portions of the rear slider plate 74 and the sorting slider plate 76, thereby preventing the rotation drive from being disturbed, stabilizing the carrot conveyance pace, and improving the sorting accuracy. .

  Furthermore, since the carrots are prevented from falling from the conveyor belt 68, the carrots are prevented from being damaged by the impact of the drop, the product value of the carrots is improved, and it is not necessary to collect the carrots that have been dropped. The labor of the person is reduced.

  In the conventional configuration, since the rear end portion of the weight detection plate and the front end portion of the slider plate are arranged substantially linearly, when the weight detection plate is pushed down by the weight of carrot, the conveyor belt is moved to the front end portion of the slider plate. Or may be sandwiched between the weight detection plate and the slider plate, and there is a problem that the transport speed of the transport conveyor is disturbed or stopped.

  When the rear slider 76b is formed with the rear bent portion 76b having a curved surface on the rear side of the machine body, the carrot is placed on the weight detecting plate 78 and moved from the selected slider plate 76. Therefore, the conveyance belt 68 does not fluctuate, the carrot conveyance pace is stabilized, and the sorting accuracy is improved.

  The front-rear length of the front bent portion 76a may be changed according to the detected weight of the weight detecting device 75 provided on the front side of the sorting slider plate 76. When the weight detected by the weight detection device 75 is heavier, the length of the front bent portion 76a is lengthened, and when the weight to be detected is lighter, the length is shortened. When the weight detection plate 78 of the weight detection device 75 moves up and down, it is pushed up. Since only the end of the carrot inclined downward in the front side can be prevented, it is possible to prevent the carrot from jumping to the next weight detection device 75, and the weight detection device 75 is erroneously detected by the impact of the carrot falling. Therefore, the sorting accuracy is improved.

  As an example, the rear side of the 3L size weight detection device 75 is about 30 to 40 mm, the 2L size is about 25 to 35 mm, the L size is about 20 to 30 mm, and the M size is about 10 to 20 mm. . In the S size portion, the front bent portion 76a is not bent, but in the present embodiment, since the S size is the last weight detection position, such a configuration is adopted in order to prevent erroneous detection. When selecting smaller ginsengs such as 2S and 3S, the front-side bent portion 76a is also formed in the S-sized portion in order to prevent erroneous detection due to ginseng jumps.

  The above-mentioned length is wide because there are various types of carrots, such as those that are long and small in the front and back, those that are short and large in the front and back, those that have a high density of pulp, etc. It is to make it.

  In addition, since the weight 80a can be taken in and out of the adjustment plate 80 and the weight detected by the weight detection device 75 can be changed, it is possible to improve the accuracy of carrot selection even if there are differences in the selection conditions such as carrot varieties and growth conditions. It is done.

  In addition, the balance weight 81 can be adjusted to finely adjust the detected weight, preventing the occurrence of carrots that do not jump out due to a slight difference in weight, improving the sorting accuracy and manually sorting the carrots. There is no need to rework, and the labor of the operator is reduced.

  Further, since the inner side of the body of the weight detection plate 78 is bent downward at a right angle and the bent portion 78a is formed, the conveyor belt 68 is less likely to tilt toward the collection shooter 93, so that the carrot is hit by the jumping device 84. Therefore, it is possible to prevent the transfer from the transfer conveyor 70 to the collection shooter 93, so that the sorting accuracy is improved and the operator does not have to re-sort, thereby reducing the labor of the worker.

  In addition, when the conveyor 70 is tilted upward by about 0.5 to 1 degree from the outside of the machine body to the inside, the carrot can move toward the outside of the machine body of the conveyor conveyor 70, so that the carrot moves to the jumping device 84. It is possible to prevent the transfer from the conveyor 70 to the collection shooter 93 without being hit, and the sorting accuracy is improved, and the operator does not have to re-sort and the labor of the worker is reduced.

  Since the front end of the intermediate plate 85 is located on the outer side of the machine body from the rear end of the jumping plate 88, when the carrot contacts the rear end of the jumping plate 88, the front end of the intermediate plate 85 ... It is possible to prevent the next ginseng from being caught and the weight detection device 75 from mistakenly identifying two as one ginseng, thereby improving the accuracy of ginseng sorting.

  Further, even if the intermediate plate 85 is not caught at the front end, it can be prevented from being rebounded by the impact of the collision and placed on the weight detection device 75 together with a strong impact, causing the weight detection device 75 to malfunction. Will improve.

In addition, it is good also as a structure which arrange | positions the rotating shaft 88a of the jumping board 88 in the outer side of the body rather than the jumping board 88, and the front side of the body of the jumping board 88 is located on the outer side of the body.
With the above configuration, the jump plate 88 and the intermediate plate 85 are arranged in a saw blade shape in a plan view, and a space portion is generated between the rear end portion of the jump plate 88 and the front end portion of the intermediate plate 85. Further, the carrots are less likely to come into contact with the tip side of the intermediate plate 85, and the weight detection device 75 can reliably detect the weight of the carrots one by one, and the sorting accuracy is further improved.

  Further, by providing the same number of recovery shooters 93... Between the left and right of the sorting conveyor 70 as the weight detection device 75 and the jumping device 84, the collection shooter of the grade corresponding to the weight of the carrot detected by the weight detection device 75 by the jumping device 84. The carrots can be collected for each grade in a container 92 such as a container.

  Then, by connecting the collection shooters 93 from above with the connection handle 94, the operator can remove the plurality of collection shooters 93 at the same time, so that a space for maintenance work is easily secured.

  Further, by providing a guide curtain 95 that receives the ginseng that has been struck and sent out by the jumping device 84 at the lower part of the connecting handle 94 and guides the carrot to the lower recovery shooter 93. It is possible to prevent the carrots from traveling to the next row conveyor 70 and riding the same car in two places, or causing the weight detection device 75 in the next row to malfunction due to the impact of dropping. Accuracy is improved.

Further, since it is possible to prevent the carrots being transported from being hit by the transport conveyor 70 in the adjacent row, the carrots are prevented from being damaged by the impact of the collision, and the product value of the carrots is maintained.
And, by providing a mounting table 95 on which a container 92 for collecting non-standard ginseng is provided at the conveyance end portion of the conveyance conveyor 70, it is only necessary to convey non-standard ginseng, which is difficult to set sorting conditions. Since it can be collected, the efficiency of the sorting work is improved.

  Further, since the mounting table 95 is provided so as to be rotatable in the front-rear direction, when the sorting and conveying unit E is stored, the mounting table 95 can be brought close to the machine body to shorten the front-rear width. Can also be stored easily.

  Since the elongated hole 109a is formed in the scraper plate 109, the position where the scraper plate 109 is attached to the support bracket 108 can be adjusted in the front-rear direction, so the front side of the scraper plate 109 when there is a lot of water or impurities When the end and the conveyor belt 68 are brought close to each other, water and contaminants are removed by the scraper plate 109, so that water and contaminants are prevented from entering the back side of the conveyor belt 68 and slipping.

  As a result, the conveyor belt 68 does not bend at the weight detection position, and the carrot is erroneously sorted in a lower grade, or the conveyor belt 68 stops and moves to a collection shooter 93 of a different grade. This can prevent the carrot sorting accuracy.

  On the other hand, when there is little water or impurities on the conveyor belt 68, the front end of the scraper plate 109 and the conveyor belt 68 are slightly separated to reduce the contact amount, thereby preventing unnecessary friction on the sorting belt 68. As a result, it is possible to prevent the sorting belt 68 from being damaged by friction and improve durability.

  Further, a long hole 108b for attachment is formed inside or outside the body of the support bracket 108, and the support bracket 108 is used as a rotation fulcrum from the horizontal position to a downward inclined posture toward the outside of the body. Since the posture can be changed, the scraper plate 109 can discharge the water and impurities scraped from the conveyor belt 68 to the outside of the machine body, so that the water and contaminants are prevented from entering the back side of the conveyor belt 68. In addition, the carrot may be erroneously sorted in a lower grade without the conveyor belt 68 being bent at the weight detection position, or the carrot may move to a collection shooter 93 of a different grade due to the reaction of the conveyor belt 68 being stopped. In addition, the accuracy of carrot sorting is improved.

  In addition, if the downward inclination angle of the scraper plate 109 to the rear of the machine body is set within a range of 45 to 60 degrees with respect to the front end of the machine body, the scraper plate 109 is not easily caught in the rotation of the conveyor belt 68. Is not bent or bent during the operation, and the durability of the scraper plate 109 is improved.

Further, since it is not necessary to replace or reassemble the scraper plate 109 that has been damaged or detached during the work, the work efficiency is improved.
Further, when the angle of the support bracket 108 that is inclined downward toward the outer side of the machine body is set in a range of 2 to 5 degrees, the scraper plate 109 functions as a shooter that sends the carrot discharged from the sorting conveyor 70 to the storage container 92. Without damaging, the water and impurities scraped from the conveyor belt 68 can be moved to the outside of the machine body and discharged.

  Hereinafter, another embodiment of the present ginseng aligning apparatus will be described. This alternative embodiment can also be incorporated into the above-described present embodiment, and does not deny a combination of techniques disclosed in the present embodiment and another embodiment.

  As shown in FIG. 22, the discharge conveyance conveyor 53 or the alignment side plate 24 is provided in a downwardly inclined posture toward the alignment conveyance conveyor 42 on the side where the feedback shooter 44 is provided, and the alignment side plate 24 is provided on the side where the feedback shooter 44 is not provided. Also, an auxiliary side plate 130 that is short in the left-right direction is provided in a downward inclined posture and slidable in the inclined direction toward the aligned conveying conveyor 42.

  In addition, an auxiliary discharge driven pulley 131 is rotatably provided below the auxiliary side plate 130 and on the upper conveyance side, an auxiliary discharge driving pulley 132 is provided on the lower conveyance side, and a rotary drive shaft on which the auxiliary discharge driving pulley 132 is mounted. An auxiliary discharge drive motor 134 for driving and rotating 132a is provided on the lower side of the auxiliary side plate 130 on the lower conveyance side.

  Then, one or a plurality of auxiliary discharge conveyance belts 133 are wound endlessly across the auxiliary discharge driven pulley 131 and the auxiliary discharge drive pulley 132, thereby forming the auxiliary discharge conveyance conveyor 135.

  The auxiliary discharge driven pulley 131 and the auxiliary discharge drive pulley 132 are provided with mounting grooves for providing a plurality of auxiliary discharge conveyance belts 133... To widen the working range of the auxiliary discharge conveyance conveyor 135. The number of 133... Is increased and the auxiliary side plate 130 is slid upward. When the operating range of the auxiliary discharge conveyor 135 is narrowed, the number of auxiliary discharge conveyor belts 133 is reduced and the auxiliary side plate 130 is slid downward.

Further, the lower side movement limit of the auxiliary side plate 130 is set to an upper part of the slide shutter 47 and a position that does not prevent the slide shutter 47 from sliding back and forth.
Furthermore, as shown in FIG. 23, the auxiliary discharge conveyance belts 133... Protrude from the auxiliary side plate 130 and the slide shutter 47 to the side of the alignment conveyance conveyor 42 by about 5 mm to 10 mm.

  In the above configuration, since the carrot that has fallen on the auxiliary side plate 130 can be conveyed to the drop shooter 43 by the auxiliary discharge conveyance conveyor 135, the carrot is prevented from staying on the auxiliary side plate 130 and returns to the hopper 2. , Work efficiency is improved.

  In addition, since the auxiliary discharge transport conveyor 135 is disposed above the slide shutter 47, even if a large amount of carrot is thrown into the alignment transport conveyor 42 when the slide shutter 47 covers one side of the alignment transport conveyor 42. Since the carrot can be dropped directly onto the discharge shooter 43 from above the slide shutter 47, a plurality of carrots can be taken over from the aligning and conveying conveyor 42 to the sorting and conveying conveyor 70 at once, or the ginseng whose posture is not adjusted can be taken over. Therefore, the sorting error of the weight sorting device 75 is prevented, and the carrot is reliably sorted by size.

  Further, it is possible to prevent the carrots from clogging and moving on the sorting and conveying conveyor 42, and the operator does not have to work to eliminate the clogged state of the carrots, so that the efficiency of the sorting work is improved and the sorting work is automated. The labor of the operator is greatly reduced.

  Further, since the number of auxiliary discharge conveyance belts 133 wound around the auxiliary discharge driven pulley 131 and the auxiliary discharge drive pulley 132 can be changed, the number of carrots to be sorted and the size of the carrot are assisted. Since the conveyance operation width of the discharge conveyance conveyor 135 can be changed, it is possible to prevent the carrot moving to the alignment conveyance conveyor 42 from dropping from the discharge shooter 43 and to return the carrot that does not need to be returned to the hopper 2. It is omitted and work efficiency is improved.

  Alternatively, as shown in FIG. 24, a first inclined side plate 136 on which the slide shutter 47 is slidably mounted along the conveying direction is provided on the aligned conveying conveyor 42 in a downward inclined posture, and the first inclined side plate 136 can be transported well. A first discharge driven roller 137 is rotatably provided on the side, and a first discharge drive roller 138 having a first discharge drive motor 139 is disposed on the lower conveyance side. And the 1st discharge conveyance belt 140 is wound endlessly over this 1st discharge driven roller 137 and the 1st discharge drive roller 138, and the 1st discharge conveyance conveyor 141 is constituted.

  Note that the lower end portion of the first discharge conveyance belt 140 covers the upper end portion of the first inclined side plate 136 over the thickness of the first discharge conveyance belt 140, for example, about 1 mm to 3 mm. Since it is possible to prevent the carrot being conveyed by the discharge conveyor 141 from coming into contact with the upper end portion of the first inclined side plate 136, the carrot is prevented from being damaged by friction, and the commercial value of the carrot is improved.

  On the other hand, the alignment side plate 24 on the side where the fixed shutter 46 is provided is provided with a second inclined side plate 142 having the same longitudinal length as the first inclined side plate 136 and a vertical length on the aligned conveying conveyor 42 side in a downward inclined posture. A second discharge driven roller 143 is rotatably provided on the upper conveyance side of the second inclined side plate 142, and a second discharge drive roller 144 having a second discharge drive motor 145 is disposed on the lower conveyance side. Then, the second discharge conveyor belt 146 is wound endlessly across the second discharge driven roller 143 and the second discharge drive roller 145 to constitute the second discharge conveyor 147.

  When the peripheral speed of the second discharge conveyor 147 and the peripheral speed of the first discharge conveyor 141 are set to be the same as the peripheral speed of the alignment conveyor 42 or slower than the peripheral speed of the alignment conveyor 42, the alignment conveyor 42 Since the carrots that have not been placed on are discharged to the drop shooter 43 without delay, it is prevented from taking too much time to return to the hopper 2 and the efficiency of the sorting operation is improved.

  Alternatively, the first discharge drive motor 139 and the second discharge drive motor 145 may be operated to increase the peripheral speed of one of the first discharge transfer conveyor 141 and the second discharge transfer conveyor 147, respectively. However, the speed is the same as or slower than the circumferential speed of the aligned transport conveyor 42.

  If the lower end of the second inclined side plate 142 is configured to cover the upper end of the second discharge conveyance belt 146 over the thickness of the second discharge conveyance belt 146, for example, about 1 mm to 3 mm, Since it is possible to prevent the second discharge conveyor belt 146 from being bent excessively due to the weight and impact when the carrot is placed on the discharge conveyor 147, the carrot falls from the second discharge conveyor 147 to the second sorting conveyor 42 and becomes clogged. It is prevented that a plurality of ginsengs and ginseng in a posture not suitable for sorting are taken over by the sorting and conveying conveyor 70, so that the work efficiency is improved and the wrong sorting of ginseng is reduced.

  Further, since it is possible to prevent the second discharge conveyance belt 146 from being detached, it is not necessary for the operator to wear the second discharge conveyance belt 146, the stop time of the sorting operation is eliminated, and the work efficiency is improved. Even if there is no person, the sorting operation can be continued, and the operation can be unmanned.

  In addition, as shown in FIG. 25, a third inclined side plate 148 that is inclined downward toward the aligned conveying conveyor 42 side is provided on the lower side of the front-rear central portion of the first discharge conveying conveyor 141 in the conveying direction, A third discharge driven roller 149 is provided on the front side of the inclined side plate 148, that is, the front side, and a driving force is applied from the first discharge transfer conveyor 141 to the lower side of the rotation shaft (not shown) of the first discharge driven roller 138. A third discharge drive roller 150 that receives and rotates is mounted.

  A plurality of belt guide grooves are formed in the third discharge driven roller 149 and the third discharge drive roller 150 in the vertical direction, and one or a plurality of belt guide grooves are formed in the third discharge driven roller 149 and the third discharge drive roller 150. The third discharge transport conveyor 152 is configured by winding the third discharge transport belts 151.

  Note that the third discharge conveyor belts 151 of the third discharge conveyor 152 protrude about 5 to 10 mm toward the aligned conveyor 42 side. When the carrot transported by the third discharge transport conveyor 152 moves to the front end portion of the slide shutter 47, the first discharge transport conveyor 141 or the carrot is moved depending on the driving force of the third discharge transport conveyor 152 and the transported vertical position. It is forcibly moved to the alignment conveyor 42.

  In the above configuration, since the third discharge conveyor 152 continues to rotate below the first discharge conveyor 141, it is possible to prevent the carrot from continuing to stay between the alignment conveyor 42 and the first discharge conveyor 141. As a result, the efficiency of the sorting work is improved, and the carrots that are discharged from the up-conveying conveyor 16 and fallen into the stagnant ginseng can be prevented and the carrots can be prevented from being damaged, thereby improving the product value of the carrots. To do.

  Further, since the carrot transported at the lower position of the third discharge transport conveyor 152 can move to the alignment transport conveyor 42 when it comes into contact with the slide shutter 47, the carrot moves too much to the falling shooter 43. It is prevented that the interval of the sorting operation is too large, and the work efficiency is improved.
