In the present embodiment, the cleaning drive device 20 includes three sets of two sets of cleaning rollers 22 and 22, and the set of cleaning rollers 22 and 22 rotates in a direction facing each other.
Although the freshly harvested carrots are covered with white thin skin, the cleaning roller 22 is also a member that removes the thin skin together with the removal of mud and impurities. This thin skin is conventionally removed before shipment, and there is no problem in quality even if it is removed at the stage of the cleaning operation.

  The cleaning roller 22 is configured by planting countless hairs (brush hairs) made of a synthetic resin or a natural material around a cylindrical resin roller, or attaching a sponge or the like to the outer peripheral surface. At this time, if the hair is inclined and planted in the transport direction, or if irregularities are formed on the surface of a sponge or the like in the transport direction, the carrot can be moved to the lower side in the transport direction while washing. Carrot stagnation in the device 26 is prevented.

  Sprinkling pipes 24 and 24 for spraying cleaning water toward the cleaning rollers 22 are provided on both the left and right sides of the cleaning frame 16 and above the cleaning transmission mechanisms 20 and 20. A plurality of watering holes are formed.

  The cleaning water is supplied to the water spray pipes 24, 24 by pumping water stored in the cleaning frame 16 below the cleaning paths 23, 23 with a pump (not shown) with a filter. 24 and 24 are connected by a hose (not shown), and a water circulation system in which water from which impurities such as mud and thin skin have been removed is sprinkled from the sprinkling pipes 24 and 24, or a tank that stores a large amount of water (not shown). And water spray pipes 24, 24 may be connected by a hose, or a water supply system may be used in which water is collected by submerging a pump in a water source such as a river or a lake, and this water is supplied to the water spray pipes 24, 24.

  Further, when the water spray holes formed in the water spray pipes 24, 24 are formed with a narrower interval toward the cleaning start end side or a larger diameter toward the transport start end side, the cleaning water is concentrated on the cleaning start end side where mud adheres heavily. The mud removal is ensured.

  And the washing | cleaning apparatus 26 is comprised by attaching to the washing | cleaning frame 16 of the washing | cleaning termination | terminus part of the said washing | cleaning path | routes 23 and 23 the doors 25 and 25 which take out the ginseng which wash | cleaned so that opening and closing is possible up and down or left and right.

  When the doors 25 and 25 are tensioned toward the cleaning frame 16 with a spring (not shown) or the like and a pressing force of a certain level or more is applied from the inside to the outside of the cleaning frame 16, the doors 25 and 25 have a pressing force. If it is configured to automatically open together, the carrots are washed and transported to the end side of the cleaning paths 23, 23, and when a certain amount or more of ginseng accumulates on the end side of the cleaning paths 23, 23, the carrot pushes the doors 25, 25 open. Therefore, it is not necessary for the operator to open and close the doors 25 and 25, and the washing and sorting work can be unmanned.

  Furthermore, it is possible to prevent the carrots from staying in the cleaning paths 23, 23 and continuing to come into contact with the cleaning roller 22 even though the cleaning operation is finished, and the skin other than the thin skin of the carrots is scraped off. The product value of carrots is improved.

The cleaning unit A is constituted by the cleaning device 26 and the charging tank 15.
With the above configuration, if the operator puts the carrot into the input tank 15 and operates the first pumping conveyor 3 and the cleaning device 26, the operation is unnecessary until the end of the carrot cleaning. And labor saving.

  In addition, the second drive motor 17 of the cleaning device 26 is disposed below the second transport unit 3b in the back-up inclined posture of the first scooping transport conveyor 3, thereby reducing the distance between the charging tank 15 and the cleaning device 26. Therefore, the entire cleaning unit A and the cleaning / sorting apparatus can be made compact.

  Furthermore, since the distance between the charging tank 15 and the cleaning device 26 is very short, the carrot does not fall at the time of takeover, and it is not necessary for the operator to pick up the dropped carrot and the work is unmanned. The carrot is prevented from being damaged by the impact of falling, and the commercial value is maintained.

Next, the storage part B will be described.
As shown in FIGS. 1, 2, 5, 7, and 8, a relay hopper 28 that stores carrots is attached to the front of the base frame 27, and a central storage in a downward inclined posture is attached to the front end of the relay hopper 28. The storage portion A is configured by attaching the inclined plates 28a and attaching the left and right storage inclined plates 28b and 28b in the downward inclined posture to the left and right side ends of the relay hopper 28, respectively.

  A mat made of a soft material such as foam rubber or sponge and having a slippery surface is attached to the entire surface of the central storage inclined plate 28a and at least the surface of the left and right storage inclined plates 28b and 28b on the upper side in the conveying direction. In this case, it is possible to prevent the carrots to be sorted discharged from the non-standard sorting section C described later from being damaged by the impact of dropping.

Next, the nonstandard screening unit C will be described.
As shown in FIGS. 1 to 3, 5, 6, 9 to 12, and 16 to 18, four support legs 29 a, 29 a, 29 a, and 29 a are arranged on the front, rear, left and right sides, and the support legs 29 a , 29a, 29a, 29a, a non-standard sorting frame 29 is configured by disposing a hollow square pillar-shaped support frame 29b. The non-standard sorting frame 29 is placed across the relay hopper 28 in the left-right direction, and the start end side is disposed at a position close to the cleaning end side of the cleaning device 26. Further, left and right field picture ring units 30, 30 provided with a plurality of bearings 30a ... are arranged in the front-rear direction on the upper left and right sides of the non-standard sorting frame 29.

  .. Are arranged above the hollow portion of the support frame 29 b and between the left and right sides of the bearing units 30, 30. The rotary shafts 31, 31 are attached to the bearings 30a of the bearing units 30, 30 so as to be close to each other. Further, taper-shaped transport rollers 32, 32 having a smaller diameter toward the lower side in the transport direction are attached to the rotary shafts 31, 31,..., And the transport rollers 32, 32 are connected to the transport start end side of the transport rollers 32, 32. A non-standard sorting / conveying device 35 is configured by axially attaching small-sized small article removing rollers 33, 33 to form non-standard sorting / conveying paths 34, 34.

  The accessory removal rollers 33 and 33 are arranged with a left-right spacing of about 10 to 20 mm in order to drop carrots of less than 2S or 3S or broken or chipped carrots. A first collection container Z1 is provided below the small article removing rollers 33 and 33 to collect the fallen ginseng and carrot fragments.

  The small object removal rollers 33 and 33 may have a tapered shape with a smaller diameter toward the conveyance end side. In this case, the diameter at the conveyance end side is larger or substantially the same as the diameter of the conveyance start end portion of the conveyance rollers 32 and 32. The diameter.

  By adopting the above configuration, since the carrots are smoothly handed over from the small article removing rollers 33, 33 to the transport rollers 32, 32, the carrots are prevented from staying at the handover part, and the work efficiency is improved.

  Further, the conveyance rollers 32 and 32 have a left and right interval of about 10 to 20 mm in a portion that takes over the carrots from the small article removal rollers 33 and 33, and in order to drop the carrots of 2 L or 3 L or less on the conveyance end side, It is arranged with a left and right interval of about 80 mm. As for the carrots transported to the transport rollers 32, 32, 2S or 3S falls immediately after being taken over from the small article removal rollers 33, 33, and S → M → L → 2L or 3L goes to the relay hopper 28 toward the end side. It will fall.

  In addition, the definition of the size may differ depending on the concept of the agricultural cooperative and the shipper, and naturally, each carrot, which is a plant, varies depending on the variety, cultivation region, cultivation method, season, and soil quality of the field. Therefore, the size and diameter of the carrot are just examples for explanation.

  At this time, a large-diameter carrot of 4L or more, or a deformed carrot that does not fall from any of the left and right intervals of the second leveling rollers 33, 33 due to bifurcation or bending, is detachably provided on the conveyance end side of the conveyance rollers 32, 32. It discharges to the 2nd collection container Z2 which collects 3L or 4L maximum carrot and malformed carrot via the discharge shooter 34a inclined downward.

  There are few maximal carrots, and malformed carrots have low product value, so both are generally not shipped as they are, but for processing that does not place importance on uniformity of size or shape Since there is demand, the sorting of carrots for processing can be finished at the stage of non-standard sorting, and the work efficiency is improved.

  If the bearing units 30L and 30R are arranged so as to be movable in the left-right direction, and one of the end portions of the rotary shafts 31 and 31 is a universal joint, a non-standard sorting and conveying path 34 and 34 is formed. Since the distance between the left and right of the small article removing rollers 33 and 33 and the conveying rollers 32 and 32 can be changed, it is possible to change the carrot sorting conditions for performing the washing and sorting operation.

  In this case, the small article removing rollers 33 and 33 and the conveying rollers 32 and 32 are used separately. However, as shown in FIGS. 20 and 22, the conveying start end side of the conveying rollers 32 and 32 is connected to the small article removing rollers 33 and 32. It is good also as the single-piece | unit selection conveyance rollers 33a and 33a formed in the same shape as 33. FIG.

  In the above configuration, the foreign matter does not enter the gap between the rollers, and it is not necessary to remove the foreign matter that has entered. In addition, when the sorting and conveying rollers 33a and 33a are replaced, the time required for the replacement work is shortened.

Further, as shown in FIGS. 19 and 21, it is possible to use the transport rollers 32 and 32 from the transport start end side to the transport end side without using the accessory removal rollers 33 and 33.
Even in the above-described configuration, the foreign matter does not enter the gap between the rollers, it is not necessary to remove the foreign matter that has entered, and the maintainability is improved, and the time required for the replacement work when the transport rollers 32 and 32 are replaced. Becomes shorter.

  Then, as shown in FIG. 18, a guide rail 42 is provided below the accessory removal rollers 33, 33, and foreign matters such as thin skin and hair roots attached to the accessory removal rollers 33, 33 are scraped off to the guide rail 42. A scraper plate 43 is slidably attached in the front-rear direction. A cutout portion slightly wider than the maximum diameter portion of the circular small article removing rollers 33 and 33 is formed on the upper portion of the scraper plate 43 so as to be movable along the outer peripheral surface of the small article removing rollers 33 and 33. .

  Further, a vibration motor 44 that vibrates the guide rail 42 is provided below the guide rail 42. Assuming that the vibration motor 44 is automatically intermittently driven, it can be removed together after some foreign matter adheres to some extent.

  The accessory removal rollers 33 and 33 have a tapered shape, and the gap increases each time the scraper plate 43 is moved to the lower side in the transport direction. However, the thin skin and the hair root attached to the accessory removal rollers 33 and 33 are basically the same. When the vibration motor 44 is operated, the scraper plate 43 randomly contacts the small object removing rollers 33 and 33 when the vibration motor 44 is operated, and can be scraped off without any problem.

  Alternatively, when arranged in a posture that is perpendicular to the normal angle of the small object removing rollers 33, 33, the vertical distance from the small object removing rollers 33, 33 is maintained constant, so that the adhering foreign matter does not have vibration or the like. Can be removed.

Further, if the scraper plate 43 is arranged so as to move back and forth at random when vibration of the vibration motor 44 is applied, the foreign matter is less likely to remain on the small article removing rollers 33 and 33.
The vibration motor 44 is capable of forward and reverse rotation, a cam (not shown) provided on the output shaft of the vibration motor 44 is a pinion, the guide rail 42 is a rack, and the vibration motor 44 is forward and reverse at predetermined intervals. Then, the foreign substances adhering to most of the small object removing rollers 33, 33 in the front-rear direction can be removed.

  Further, wipers 45 for removing water adhering to the small article removing rollers 33, 33 from the washed carrots are attached to the lower parts of the small article removing rollers 33, 33 in the longitudinal direction of the small article removing rollers 33, 33, respectively. The wiper 45 is connected to the scraper plate 43 so as not to interfere with the front / rear slide of the scraper plate 43, and is configured to slide back and forth in conjunction with the front / rear slide. Alternatively, a notch for avoiding the wiper 45 may be formed in the scraper plate 43 so that the scraper plate 43 does not contact the wiper 45 when sliding back and forth.

  And one side of the extended rotary shaft 36 is attached to the conveyance start end side of the rotary shafts 31, 31..., And the other side of the extended rotary shaft 36 is connected to the cleaning rotary shaft 21, so By securing the driving force of 35, the nonstandard screening unit C is configured.

  With the above configuration, the smallest ginseng and debris are discharged to the first collection container Z1 on the conveyance start end side of the non-standard sorting conveyance paths 34, 34, so that the smallest ginseng and debris enter the sorting conveyance device 76 described later, and the weight And the length of the carrot can be prevented from being erroneously detected, and the carrot sorting accuracy is improved.

  In addition, since it is possible to prevent the mixture of small carrots and debris into the fourth collection container Z4 that collects small carrots of 2S or 3S size at the transport terminal of the sorting and conveying device 76, manual sorting becomes unnecessary. The work efficiency is improved and the labor of the worker is reduced.

  And since the smallest ginseng, debris, beard root, thin skin, etc. which were returned to the field in the past are collected in the 1st collection container Z1, the operator does not sort out the contents, and the smallest ginseng, debris, roots. And the skin can be returned to the field, reducing the labor of the operator.

  Furthermore, since too large carrots and malformed carrots are discharged to the second collection container Z2 from the transport end of the non-standard sorting transport paths 34, 34, the sorting position of the sorting and transporting device is the maximum size (2L or 3L). Although sorting is performed, carrots (3L and 4L) that are too small in number to hinder grade unification can be removed in advance, and the sorting accuracy is improved.

  In addition, although the weight and length are the same as normal carrots, it is possible to remove malformed carrots that have a shape problem such as bifurcation or bending, so the time required to remove malformed carrots from each sorting grade Is reduced and the labor of the operator is also reduced.

  Since the transport rollers 32 and 32 are tapered, the carrot having a size and shape suitable for shipping as a product can be transported and dropped onto the relay hopper 28 on the way. There is no need to move it, and work can be automated and unmanned.

  Furthermore, by providing a scraper plate 43 that removes foreign substances below the small object removing rollers 33 and 33 so as to be slidable in the front-rear direction, carrot roots and thin skin deposited on the small object removing rollers 33 and 33 can be easily removed. Therefore, it is possible to prevent a small amount of ginseng from adhering to a large amount and increasing the diameter of the small object removing rollers 33 and 33 and passing a ginseng which should have dropped from passing through the small object removing rollers 33 and 33. Sorting accuracy is improved.

  Moreover, since the space | interval of the scraper plate 43 and the small article removal rollers 33 and 33 becomes narrow by vibrating the scraper plate 43 with the vibration motor 44, a foreign material can be removed reliably.

  Further, by providing the wiper 45 that removes moisture in the front-rear direction of the accessory removal rollers 33, 33, it is possible to prevent extra moisture from adhering to the carrot falling on the relay hopper 28. In addition, the sorting / conveying device 76 is prevented from being hindered by moisture, and the work efficiency and sorting accuracy are improved.

  When the rotary shaft 31 and the cleaning rotary shaft 21 are connected via the extended rotary shaft 36, the cleaning rotary shaft 21 uses a set of two pieces located at the bottom of the cleaning path 23. Since the vertical height of the non-standard sorting / conveying device 35 can be kept low and is substantially linear, the transmission system is simply configured.

  On the other hand, as shown in FIGS. 13 to 15, a plurality of transmission sprockets 37 that are rotatable and movable in the left-right direction, and a transmission chain 38 that is wound endlessly around the plurality of transmission sprockets 37 are incorporated. A drive unit 41 is constituted by a case 39 and a third drive motor 40 that supplies a drive force to the transmission case 39, and a rotation shaft of a transmission sprocket 37 of the drive unit 41 and a rotation shaft 31 of a nonstandard sorting and conveying device 35. , 31..., 31...

  With the above configuration, the driving speed of the non-standard sorting / conveying device 35 can be set to a speed different from that of the cleaning device 26. Therefore, when the amount of carrot discharged from the cleaning device 26 is large, the carrot is transported at a higher speed. As a result, carrots are prevented from staying in the discharge position of the cleaning device 26 or the non-standard sorting and conveying paths 34, 34, and the work efficiency is improved.

Further, since no extra load is applied to the cleaning transmission mechanisms 20 and 20 and the second drive motor 17 of the cleaning device, the durability is improved.
Next, the draw-up conveyance unit D will be described.

  As shown in FIGS. 1, 2, 5, 7, and 8, a first relay conveyor 46 is provided at the inner lower portion of the relay hopper 28 to convey ginseng from which nonstandard products have been removed in a straight line. A second relay conveyor 47 in a rear-upward inclined posture is disposed at the transfer terminal end of the relay conveyor 46. Then, by attaching a discharge shooter 48 for discharging carrots to the terminal portion of the second relay conveyor 47, a relay pumping conveyor 49 is configured.

  If the discharge shooter 48 is made of a soft material such as vinyl chloride or sponge, it can be placed on the transfer start end of the left and right first aligned transfer conveyors 54 and 54 immediately below the transfer end of the relay pumping conveyor 49, thereby improving efficiency. Carrots can be well aligned and transported, and the carrots can be prevented from coming into contact with the end of the discharge shooter 48 and being damaged.

  Then, a support base 50 is attached to the upper side of the base frame 27 in the front-rear direction and a fourth drive motor 51 for supplying a driving force to the relay pumping conveyor 49 is disposed above the support base 50. , A pumping conveyance unit D is configured.

  With the above configuration, the carrot that has fallen from the non-standard sorting section C to the storage section B can be received by the relay pumping conveyor 49 and automatically sent to the alignment transport section E, which will be described later. Is planned.

Next, the alignment transport unit E will be described.
As shown in FIGS. 1, 7, and 8, an alignment conveyance frame 52 is attached to the upper rear side of the base frame 27, and side plates 53 and 53 are attached to the left and right sides of the upper portion of the alignment conveyance frame 52. Then, left and right first alignment transport conveyors 54, 54 that receive and transport the carrot discharged from the relay scooping conveyor 49 are disposed in the vicinity of the inside of the side plates 53, 53, and the first alignment transport conveyors 54, 54 are arranged. The second alignment conveyors 55 and 55 are arranged at the conveyance end portion, taking over the carrots from the first alignment conveyors 54 and 54, adjusting the posture one by one and conveying them while arranging them.

  In addition, a mountain that distributes the carrot discharged from the transfer end of the draw-up transfer conveyor 49 to either the left or right of the first transfer conveyors 54, 54 at the substantially central portion between the left and right sides of the first transfer conveyors 54, 54. A mold distribution plate 56 is attached. Further, the ginseng which is not in the posture or the ginseng being conveyed in a batch is dropped to the rear side of the distribution plate 56 and to the side of the second alignment conveyers 55, 55, and the left and right second alignment is performed. By forming left and right openings 57 and 57 that pass through the lower space of the conveyors 55 and 55 and move in the left and right outer direction of the machine body, the alignment and conveyance device 75 is configured.

  If a soft plate made of vinyl chloride or the like having a flat surface is laid on the upper surface of the distribution plate 56, ginseng is easier to slide down than simply sliding the inclined surface. Since the carrots stagnate above and no manual work is required to return to the first conveyors 54 and 54, automation and unmanned operation are achieved, and work efficiency is improved, and alignment accuracy and sorting accuracy are improved. To do.

  When a carrot is dropped from the up-conveying conveyor 49 to the distribution plate 56, that is, a cushion material having a thickness of about 3 to 5 mm is laid along the mountain shape at the front portion of the distribution plate 56. Since the carrot can be prevented from being damaged by the impact of falling, the product value of the carrot is improved.

  Furthermore, if the length of the left and right openings 57 and 57 is set to about 240 mm to 400 mm, even if two ginsengs having an average length (120 to 200 mm) enter the left and right openings 57 and 57 at the same time. Since the left and right openings 57 and 57 are prevented from being clogged, it is not necessary for the operator to remove the clogged carrot, and the work efficiency is improved.

  The first alignment transport conveyors 54 and 54 and the second alignment transport conveyors 55 and 55 are set so that the transport speed of the second alignment transport conveyors 55 and 55 is slightly higher than the transport speed of the first alignment transport conveyors 54 and 54. When the carrots are handed over from the first aligned transport conveyors 54, 54 to the second aligned transport conveyors 55, 55, the distance between the carrots being transported is widened due to the difference in transport speed, and there are a plurality of carrots. At the same time, it becomes difficult to be discharged to the sorting and conveying section F, and the sorting accuracy is improved.

At this time, since the smallest ginseng that is easily moved in a group is removed by the non-standard sorting section C, the intervals between the carrots can be surely separated.
The first alignment conveyors 54 and 54 and the second alignment conveyors 55 and 55 may be connected to a drive system in order to drive both by the fifth drive motor 59 alone. When connecting the drive system, the transfer speed of the second aligned transport conveyors 55, 55 is set slightly higher than the transport speed of the first aligned transport conveyors 54, 54 by changing the diameter of gears, sprockets, etc. And

  Then, the ginseng transport posture is adjusted and moved above the openings 57 and 57 in front of the left and right openings 57 and 57 and above the transport path of the second alignment transport conveyors 55 and 55, and the second alignment is performed. When a plurality of carrots are placed on the transport conveyors 55, 55, a pair of left and right first guide plates 60, 60 for dropping excess carrots into the left and right openings 57, 57 are arranged on the second alignment transport conveyor 55, Attach to the top of 55.

In addition, it is good to set the left-right space | interval of the conveyance lower side edge part of this 1st guide plates 60 and 60 to about 60-80 mm which is a space | interval which one large carrot can pass.
Then, the posture of the carrots whose posture is disturbed when passing over the openings 57, 57 on the rear side of the openings 57, 57 and above the transport paths of the left and right second aligned transport conveyors 55, 55 is corrected. At the same time, the left and right second guide plates 61 and 61 that are dropped into the openings 57 and 57 when the carrots coming out of the second alignment and conveying conveyors 55 and 55 come into contact with each other due to the posture are disturbed are narrower toward the lower side in the conveying direction. Attach as shown.

  The left-right distance between the lower ends of the second guide plates 61, 61 is set to be larger than the left-right distance 51 between the lower ends of the first guide plates 60, 60. Specifically, it may be set to about 80 to 100 mm, which is an interval at which ginseng that is oriented laterally with respect to the conveyance direction of the left and right second aligned conveyance conveyors 55 and 55 can pass while correcting the posture.

  Further, if the left and right first guide plates 60 and 60 and the second guide plates 61 and 61 are made of a soft material such as soft rubber or vinyl chloride, the carrot can be prevented from being damaged, so that the product value of the carrot is improved. In addition, since the carrot is flexibly bent when it comes into contact with the carrot, it is prevented that the carrot being conveyed is stagnated, and the work efficiency is improved.

  Further, the left and right feedback shooters 64 and 64 for allowing the carrot to flow down to the relay hopper 28 are inclined downward toward the upper side in the transport direction and detachably attached to the outside of the discharge ports of the openings 57 and 57, thereby aligning and transporting. Part E is configured.

  In addition, if a flat vinyl chloride plate or the like is laid on the surfaces of the openings 57 and 57 and the left and right feedback shooters 64 and 64, since the impact of falling on the carrot is absorbed, the carrot may be damaged. This will prevent the product value from increasing. In addition, by laying a flat vinyl chloride plate or the like, ginseng is easily slid down from the left and right openings 57 and 57 and the left and right feedback shooters 64 and 64. Therefore, the left and right openings 57 and 57 and the left and right feedback shooters 64, Since the work of manually returning the carrots stopped on 64 to the relay hopper 28 is omitted, the labor of the operator can be reduced, and the automation and unmanned alignment work can be achieved, thus improving the work efficiency. To do.

  According to the above configuration, by providing the mountain-shaped distribution plate 56 below the conveyance end portion of the relay pumping conveyor 49, the left and right first aligned conveyance of the carrot discharged from the terminal portion of the relay pumping conveyor 49 Since it can be sent to either the left or right side of the conveyors 54, 54, it is possible to automate the alignment work and improve the work efficiency.

  And by forming the left and right openings 57, 57 in the distribution plate 56, the carrots riding on the left and right second aligned transport conveyors 55, 55 in an unstable posture or a plurality of carrots riding simultaneously are dropped. Since the carrots discharged from the left and right second aligned transport conveyors 55 and 55 are discharged in a stable posture and one by one, the carrots are prevented from colliding with each other and being damaged, and the carrot products The value is improved, and since the carrots are put one by one into the sorting and conveying unit F arranged at the rear of the sorting and conveying unit E, the erroneous sorting is reduced and the sorting accuracy is improved.

  Further, the left and right feedback shooters 64, 64 for allowing the dropped carrot to flow down to the relay hopper 28 are provided on the outer sides of the outlets of the left and right openings 57, 57 so as to be inclined downward toward the upper side in the transport direction. Since the carrots dropped from the alignment conveyors 55 and 55 can be automatically returned to the relay hopper 28 and transported again to the relay conveyor 49, the labor of the operator is reduced by automating and unmanned operations. As a result, work efficiency is improved.

  In addition, if the height difference in the takeover portion between the first and second conveyors 54 and 54 and the second and second conveyors 55 and 55 is set to about 10 to 15 mm, the carrot posture is less likely to be shaken at the time of takeover. The work efficiency is further improved by being smoothly taken over by the second alignment conveyers 55 and 55.

  Further, by providing the first guide plates 60, 60 at the front end portions of the left and right openings 57, 57, the carrots that are handed over from the left and right first alignment transport conveyors 54, 54 to the left and right second alignment transport conveyors 55, 55 are provided. The first guide plates 60 and 60 adjust the transport posture of one carrot and remove the overlapped ginseng from the left and right openings 57, even if the transport posture of the carrot is disturbed or a plurality of carrots are stacked and taken over. Since the carrot is dropped downward from 57, all carrots are dropped at the time of takeover, and it is possible to prevent the gap between the carrots that have been aligned and transported and the carrots that are being aligned and transported from being opened too much, thereby improving work efficiency.

  Further, by providing the left and right second guide plates 61 and 61 at the rear end portions of the left and right openings 57 and 57, the posture of the carrot may be disturbed during the conveyance by the left and right second alignment conveyance conveyors 55 and 55. Even if it exists, since the conveyance posture is corrected by the second guide plates 61, 61, all the carrots fall from the left and right openings 57, 57 before being discharged from the second alignment conveyance conveyors 55, 55, and are aligned and conveyed. Since it is prevented that the gap between the carrots that have been done and the carrots being aligned and transported is too wide, work efficiency is improved.

  And since the left-right space | interval formed between the conveyance lower side edge parts of the 2nd guide plates 61 and 61 was set larger than the left-right space | interval of the 1st guide plates 60 and 60, the conveyance attitude | position of a carrot is a 2nd alignment conveyance conveyor. Even if the second guide plates 61 and 61 are oriented laterally with respect to the conveyance direction of 55 and 55, the posture of the carrots can be corrected to the posture along the conveyance direction of the left and right second aligned conveyance conveyors 55 and 55. Therefore, it is prevented that one carrot placed on the left and right second aligned transport conveyors 55, 55 is dropped, and the number of carrots returning to the relay hopper 28 is reduced, so that the work efficiency is improved.

  Furthermore, by providing the left and right feedback shooters 64, 64 outside the left and right openings 57, 57, ginseng that has dropped from the left and right openings 57, 57 automatically flows down to the relay hopper 28. It is not necessary to return the carrot to the relay hopper 28, and the work efficiency is improved.

Next, the sorting and conveying unit F will be described.
As shown in FIGS. 1, 7, and 8, a sorting frame 65 is disposed behind the alignment conveyance unit E, and a sixth drive motor 66 is provided at a lower rear portion of the sorting frame 65, and the sixth drive motor 66 A motor cover 67 is provided on the top of the motor.

  The left and right sorting and transporting conveyors 68 and 68 for transporting the carrot from the front side to the rear side of the machine body are arranged inside the sorting frame 65 and on both the left and right sides. The driving motor 66 is used for driving.

  In addition, the rear descending inclination posture in which the carrot discharged from the transfer device E is received and moved to the transport conveyors 68 and 68 at a position above the transport start end of the left and right sorting transport conveyors 68 and 68 and above the sorting frame 65. The left and right takeover shooters 69, 69 are detachably arranged.

  The takeover shooters 69, 69 are formed so that the front-rear length of the central portion in the left-right direction is the same as or shorter than about one 2S size carrot (about 60-80 mm), and as it goes toward the left and right ends. The front and rear widths are long, and the left and right ends are formed with a length (about 100 to 150 mm) that can support about 40% to 60% of the total length of the 3L carrot. With this configuration, the rear side of the takeover shooters 69 and 69 is formed in a V shape (C shape) in plan view.

  Also, the contact surface (surface) of the takeover shooters 69, 69 with the carrot is coated with a slippery resin material, and the rear end of this coating extends rearward from the rear end of the takeover shooters 69, 69. Let

  As shown in the figure, a weight detection device 70 for detecting the weight of carrots in the lower part of the transport path of the sorting transport conveyors 68, 68, and a carrot having a set weight or more, toward a recovery unit described later. A plurality of jumping devices 71... Further, a collection shooter 72 for moving the carrots bounced from the jumping devices 71 to a third collection container Z3 for collecting grades is arranged between the left and right of the left and right sorting and conveying conveyors 68, 68. Thus, the sorting and conveying device 76 is configured.

  When the weight detection devices 70 are arranged in the order of heavier to lighter, for example, 3L → 2L → L → M → S, it is only necessary to set the lower limit value of the weight of the carrot that operates the jumping devices 71. This makes it easy to set sorting conditions. When sorting from the lighter one, it is necessary to set a lower limit value and an upper limit value of the detected weight for each grade, and it takes time to set the sorting conditions.

  Also, the collection shooter 72. A third collection container Z3 for collecting ginseng sorted according to grade is arranged below the collection shooters 72, arranged side by side from the heavy guide side to the light guide side. Deploy.

  Further, left and right on which a fourth collection container Z4 for collecting small carrots (2S or 3S size) that has not been detected by any of the weight detection devices 70... Are placed so as to be rotatable in the longitudinal direction of the machine body. And the transfer which moves the carrot discharged | emitted from the conveyance conveyors 68 and 68 between the said conveyance conveyors 68 and 68 and the mounting bases 73 and 73 to the machine body rear end part side of the selection flame | frame 65 to the 4th collection container Z4. By attaching the shooters 74, 74, the sorting and conveying unit F is configured.

With the above configuration, the left and right transport conveyors 68 and 68 can be driven by one sixth drive motor 66, so that the number of parts is reduced, thereby reducing costs and saving resources.
In addition, since the transfer speeds of the left and right transfer conveyors 68 and 68 are substantially the same, the efficiency of the left and right sorting operations can be made substantially the same. Efficiency is improved.

  Further, by reducing the front-rear width of the central portion of the takeover shooter 69, when a carrot having a small size, for example, 2S to 4S size, floats and moves down the takeover shooter 69, it is conveyed before staying on the takeover shooter 69. Since it is moved to the conveyor 74, two or more ginsengs join together in the takeover shooter 69, and it is possible to prevent two or more ginsengs from simultaneously detecting the weight by the weight detection device 70. Two small carrots are not mistaken for one large carrot and the jumping device is not operated, so that 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, a coating portion is formed on the working surface of the takeover shooter 69, and an end of the coating portion is protruded rearward from the rear end portion of the takeover shooter 69, whereby a sharp edge of the rear end portion of the takeover shooter 69 is obtained. Since the carrot can be prevented from coming into contact with the carrot, the carrot is prevented from being damaged, and the product value of the carrot is improved.

As a result, the takeover shooter 69 can be made of a sturdy material such as a metal plate, so that the takeover shooter 69 can be easily attached and the durability is improved.
Further, by providing the same number of recovery shooters 72 as the weight detection devices 70 and the jumping devices 71 between the left and right sorting conveyors 68 and 68, the jumping device 71 can extract the carrot of the weight detected by the weight detection device 70. The carrot can be collected for each grade by the third collection container Z3 by sending it to the collection shooter 72 of the corresponding grade.

  And the left and right mountings for mounting the fourth collection container Z4 for collecting small carrots (2S or 3S) whose weight is not detected by any of the weight detection devices 70... By providing the pedestals 73 and 73, the weight detection device 70, the jumping device 71, and the recovery shooter 72 corresponding to a small carrot are not necessary, and thus the cost can be reduced.

Moreover, since the setting range of the weight to detect small carrots is wider than the detection weight of large carrots, the selection accuracy is improved without the weight detection.
In addition, the cleaning part A, the storage part B, the non-standard sorting part C, the pumping transport part D, the alignment transport part E, and the sorting transport part F constituting the carrot cleaning and sorting apparatus are the non-standard sorting part C and the storage part B. If the work is performed in the order of cleaning → non-standard sorting → alignment → sorting, the direction is the size and shape of the work place, and the worker can easily perform the work. You can change it arbitrarily.

  For example, when the non-standard sorting / conveying device 35 and the cleaning device 26 are arranged in a straight line, the rotating shaft 31... And the cleaning rotating shaft 21. When the sorting / conveying device 35 is disposed at a right angle, the rotary shafts 31 are connected to the drive unit 41 so that it can be driven even if the arrangement direction is changed.

  In addition, the alignment transport unit E can be directed in the same direction as the transport direction of the relay pumping conveyor 49 of the pumping transport unit D and can be directed in a direction orthogonal to the transport direction of the relay pumping conveyor 49.

Hereinafter, another embodiment of the ginseng cleaning and sorting apparatus will be described.
As shown in FIG. 23, the support frame 29b constituting the non-standard sorting frame 29 is slidably moved along the hollow portion into the hollow fixed-side support frame 29b1 and the hollow portion of the fixed-side support frame 29b1. A side support frame 29b2 is inserted to form a support seedling frame 29bS whose left and right lengths are adjustable.

  The fixed-side support frame 29b1 and the moving-side support frame 29b2 are configured such that one of the diameters is larger than the other diameter, and a plurality of holes are formed in the fixed-side support frame 29b1 to move the moving side support frame 29b1. One or a plurality of positioning holes are formed in the support frame 29b2, and these holes are combined and fixed with a fixing member such as a screw or a bolt and a nut to determine the left and right lengths.

Or it is set as the structure which forms the elongate hole of the left-right direction in both the fixed side support frame 29b1 and the movement side support frame 29b2, and provides a stopper (not shown) so that a movement along both the elongate holes is possible.
The rotary shafts 31 and 31 are pivotally attached to the support shafts 31a and 31a that are pivotally attached to the bearing case 30L on the fixed support frame 29b1 side, and the bearing cases 30 that are provided on the movable support frame 29b2 side. The side is divided into moving shafts 31b and 31b. Further, the support shafts 31a, 31a and the moving shafts 31b, 31b are respectively attached to the transport rollers 32, 32 so as to be capable of adjusting the left and right lengths of the support seedling frame 29bS.

  When the left and right lengths of the support seedling frame 29bS are made the shortest, the carrots discharged from the transfer end portions of the nonstandard sorting transfer paths 34 and 34 as in the present embodiment are discharged through the discharge shooters 34a and 34a into the second collection container Z2. Get in.

  On the other hand, when the left and right length of the instructing seedling frame 29bS is maximized, a portion where the moving shafts 31b, 31b,... Are exposed is generated between the conveying end portions of the conveying rollers 32 and 32 and the supporting seedling frame 29bS. At this time, the second collection container Z2 is moved below the exposed portion of the moving shafts 31b, 31b, so that a large 3L or 4L size carrot or malformed carrot from the transport terminal end of the transport rollers 32, 32 It is set as the structure dropped to the collection container Z2. Since the discharge shooters 34a, 34a mainly composed of elastic members cannot be used, there is an increased possibility of carrots being damaged by the impact of dropping, but since the products are shipped for processing that does not place importance on the appearance, the product value is reduced even if they are damaged There is no problem because it is hard to become.

  If it is desired to prevent the carrot from being scratched in this state, the discharge shooter 34a can be mounted on the second collection container Z2, and the discharge shooter 34a is provided below the conveyance end portions of the conveyance rollers 32 and 32. Good.

  With the above configuration, the left and right lengths of the non-standard sorting device 35 can be changed in accordance with the width of the relay hopper 28. Therefore, it is easy to match the width and shape of the work place and the layout desired by the operator. Work efficiency is improved and work efficiency is improved.
