  The second interval 52a at the lower end of the transport guide side of the second guide plates 52, 52 is greater than the first interval 51a at the end of the transport guide side of the first guide plates 51, 51. It is good to set to about 80-100 mm which is the space | interval which can pass the carrot which became sideways with respect to the conveyance direction of the conveyance conveyors 48 and 48, correct | amending an attitude | position.

  Further, if the left and right first guide plates 51 and 51 and the second guide plates 52 and 52 are made of a soft material such as soft rubber or vinyl chloride, the carrots can be prevented from being damaged, so that the product value of the carrots 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.

  In addition, if a flat vinyl chloride plate or the like is laid on the surfaces of the inside / outside selection outlets 26i, 26o and the left and right feedback shooters 54, 54, the impact of falling on the carrot is absorbed, so the carrot is damaged. The product value is improved by preventing the sticking. In addition, by laying a flat vinyl chloride plate or the like, the carrots can easily slide down from the inside / outside selected outside outlets 26i, 26o and the left and right feedback shooters 54, 54, so the inside / outside selected outside outlets 26i, 26o and the left / right feedback shooter Since the work of manually returning the carrots stopped on 54, 54 to the hopper 2 is omitted, the labor of the operator can be reduced and the automation of the aligning and conveying work can be achieved, so that the work efficiency is improved.

  According to the above configuration, by providing the mountain-shaped distribution plate 25 below the conveyance end portion of the draw-up conveyance conveyor 16, the left and right first aligned conveyance conveyor Since it can be sent to either one of the left and right sides of 37, 37, the alignment work can be automated, and the work efficiency is improved.

  And by forming the inside / outside selection outlets 26i, 26o on the distribution plate 25, the carrots riding on the second left and right second aligned transport conveyors 48, 48 in an unstable posture or the carrots riding on a plurality of them at the same time are dropped. Since the carrots discharged from the left and right second aligned transport conveyors 48 and 48 are discharged in a stable posture and one by one, it is possible to prevent the carrots from colliding with each other at the time of discharge and preventing the carrots from being damaged. In addition to improving the value of the product, when the sorting and conveying unit D that performs sorting operations according to the size and shape of the carrots is installed at the rear of the sorting and conveying unit C, the missorting is reduced by introducing the carrots one by one. be able to.

  Furthermore, left and right feedback shooters 54, 54 for allowing the ginseng to flow down to the hopper 2 are provided on the outer sides of the outlets 26i, 26o of the outside / inside selection outlets 26o, 26o so as to be inclined downward toward the upper side in the transport direction. Since the carrots dropped from the alignment conveyors 48, 48 can be automatically returned to the hopper 2 and transported again by the pumping conveyor 16, the work can be unmanned and the labor of the operator can be reduced. Work efficiency is improved.

  Further, the left and right first alignment and conveyance conveyors 37 and 37 are thinner than the left and right first alignment and conveyance belts 35i and 35o and the left and right first alignment and conveyance belts 35i and 35o provided between the left and right first alignment and conveyance belts 35i and 35o. Since it is composed of three belts of the central transport belt 49 (with a short vertical width), the left and right first aligned transport conveyors 37 and 37 have a concave shape when viewed from the front (back view). Therefore, the ginseng can be transported in the longitudinal direction along the transport direction of the alignment conveyor 50. The left and right second align transport conveyors 48, 48 It is easy to send carrots with good posture one by one, and the alignment accuracy improves.

  The central transport belts 37 and 37 are wound around the second drive pulleys 43 and 43 on the transport start end side of the left and right first aligned transport conveyors 37 and 37 and the left and right second aligned transport conveyors 48 and 48. Since there is no gap between the first alignment conveyors 37, 37 and the left and right second alignment conveyors 48, 48, it is possible to prevent clogging of ginseng with a small size such as thin ginseng at the tip or poor growth in the gap. In addition, since it is not necessary for the operator to remove the carrot clogged by manual work, the work can be automated, and it is possible to prevent the carrot alignment and conveyance from stagnation, thereby improving the work efficiency.

  Further, the left and right second drive pulleys 43 and 43 are configured such that the receiving pulley 42 is rotatably provided between the pair of left and right third drive pulleys 41i and 41o, whereby the left and right third drive pulleys 41i and 41o are configured. When driving the left and right second aligned transport conveyors 38, 38 by rotating the second drive shaft 40, the receiving pulley 42 rotates at the same speed as the left and right first aligned transport conveyors 37, 37 by rotating the central transport belts 49, 49. If the speed difference between the left and right first aligned transport conveyors 37 and 37 and the left and right second aligned transport conveyors 48 and 48 is different, the left and right first aligned transport conveyors 37 and 37 can move the second left and right aligned lines. When handing over the carrots to the transport conveyors 48, 48, the distance between the carrots can be increased.

  In addition, since the central conveyance belts 49 and 49 close the gaps between the left and right first alignment conveyance conveyors 37 and 37 and the left and right second alignment conveyance conveyors 48 and 48, a carrot of a very small size such as a thin ginseng at a tip portion or a growth failure is generated. It is possible to prevent clogging, and it becomes unnecessary for the operator to remove the carrot that has been manually clogged, so that the work can be automated and the alignment and transportation of the carrot can be prevented from stagnation, so that the work efficiency is improved.

  In addition, the conveyance speed V1 of the first alignment conveyance conveyor 37 is 0.2 to 0.3 m / S, and the conveyance speed V2 of the second alignment conveyance conveyor 48 is 0.4 to 0.5 m / S, that is, the second alignment conveyance conveyor. When the conveyance speed V2 of 48 is set to about twice the conveyance speed V1 of the first alignment conveyance conveyor 37, when carrots are handed over from the left and right first alignment conveyance conveyors 37, 37 to the left and right second alignment conveyance conveyors 48, 48. Since the gap between the carrots can be increased, the sorting accuracy is further improved.

  Further, by attaching flanges 45, 45 having a diameter larger than that of the left and right second drive pulleys 43, 43 on both the inner and outer sides of the left and right second drive pulleys 43, 43, the left and right first aligned transport conveyors 37, 37 and the second Since the difference in height between the transfer parts of the alignment conveyors 48 and 48 is reduced, the carrot can be transferred smoothly and the work efficiency is improved.

  If the difference in height between the left and right first aligned transport conveyors 37 and 37 and the left and right second aligned transport conveyors 48 and 48 is set to about 10 to 15 mm, the posture of the carrot is less likely to be shaken at the time of handover. Since the carrots are smoothly transferred to the left and right second aligned transfer conveyors 48, 48, the work efficiency is further improved.

  The transport speeds of the left and right first aligned transport conveyors 37 and 37, the left and right second aligned transport conveyors 48 and 48, and the scooping transport conveyor 16 are controlled by an operating device (not shown) provided in the scooping transport section B.

  Further, by providing the first guide plates 51, 51 at the front end portions of the inside / outside selection outlets 26i, 26o, the carrots to be handed over from the left and right first aligned transport conveyors 37, 37 to the left and right second aligned transport conveyors 48, 48 Even if the transport posture of the carrot is disturbed or a plurality of carrots are piled up and taken over, the first guide plates 51 and 51 adjust the transport posture of one carrot and remove the overlapping carrots from inside and outside Since the carrots 26i and 26o are dropped, all the carrots are dropped at the time of takeover, and the gap between the carrots that have been transported in alignment and the carrots that are being transported in alignment is prevented from being opened too much, thereby improving work efficiency.

  In addition, by providing the left and right second guide plates 52 and 52 at the rear end portions of the inside / outside selection outlets 26i and 26o, the posture of the carrot may be disturbed while being transported by the left and right second aligned transport conveyors 48 and 48. Even if it exists, since the conveyance posture is corrected by the second guide plates 52, 52, all the carrots have fallen from the inside / outside selection outlets 26i, 26o before being discharged from the alignment conveyor 50, and have been aligned and transferred. Since it is prevented that the distance between the carrot and the carrot being aligned and transported is too large, the work efficiency is improved.

  Since the second interval 52a formed between the lower end portions of the second guide plates 52 and 52 on the lower conveyance side is set larger than the first interval 51a of the first guide plates 51 and 51, the conveyance posture of the carrots is changed to the left and right. Even if the second alignment transport conveyors 48 and 48 are oriented laterally with respect to the transport direction, the left and right second guide plates 52 and 52 follow the transport direction of the left and right second alignment transport conveyors 48 and 48. Since it can be corrected to the right posture, it is prevented that one carrot placed on the second left and right second aligned conveyors 48, 48 is dropped, and the number of carrots returning to the hopper 2 is reduced, so that the work efficiency is improved. To do.

  Furthermore, since the left and right feedback shooters 54, 54 are provided outside the inside / outside selected outside outlets 26i, 26o, the ginseng that has fallen from the inside / outside outside selected outlets 26i, 26o automatically flows down to the hopper 2. However, it is not necessary to return the carrot to the hopper 2 and the work efficiency is improved.

  In addition, the left and right discharge shooters 53 and 53 provided below the inside / outside selection outlets 26i and 26o may be used as discharge conveyors to forcibly feed the carrots to the left and right feedback shooters 54 so that clogging does not occur.

As a wrinkle belt formed with protrusions, ginseng is prevented from overflowing to the left and right feedback shooter 54, and the front and rear length is equal to or longer than two ginsengs (about 400 mm), so that the carrots are conveyed backward even if they overlap.

  Further, the conveyance speed of the left and right side conveyors 120R and 120L is substantially the same as or higher than the conveyance speed of the first alignment conveyor 37, so that the carrots can easily move on the first alignment conveyor 37.

  The front and rear widths of the left and right central feed conveyors 121R and 121L are equal to or less than one carrot, and a flat belt with a smooth surface, and the transport speed is made faster than the transport speed of the first alignment transport conveyor 37 to obstruct the rear transport of carrot. Without carrying out, it conveys quickly toward the 1st alignment conveyance conveyor 37. FIG.

The left and right openings 26R, 26L are provided up to the end of the first alignment conveyer 37, and the opening adjustment shutter 115 is used in a fully closed state at the opening 26R on one side. The opening adjustment shutter 115 is used for maintenance. Since it is provided, it is possible to eliminate the opening 26R itself on one side.
The front and rear lengths of the left and right openings 26R and 26L are not less than two carrots (about 400 mm) so that the carrots on the first alignment conveyor 37 are not stagnated.

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. 7 to 15, a sorting frame 55 is arranged behind the aligning and conveying section C, and a drive motor 56 having an output sprocket 57 mounted on the output shaft at the lower rear side of the sorting frame 55 and on the left and right sides. And 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.

  In addition, left and right second output sprockets 62 and 62 are pivotally attached to the counter shaft 60, and left and right drive rotation shafts 63 and 63 are provided above the second output sprockets 62 and 62, and the drive rotation shafts 63 and 63 are provided. The left and right second input sprockets 64, 64 are rotatably mounted. Further, the second transmission chain 65, 65 is wound around the second input sprockets 64, 64 and the second output sprockets 62, 62 to form a transmission path of the sorting and conveying unit E.

  Then, left and right drive rollers 66, 66 having V-shaped grooves formed on the circumference are provided at the ends of the drive rotating shafts 63, 63, and the selection frame is substantially at the same vertical position as the drive rollers 66, 66. The left and right driven rollers 67 and 67 having V-shaped grooves formed on the circumference are provided rotatably on the front side of the machine body 55. Further, the left and right conveying belts 68, 68 provided with protrusions 68a that enter the V-shaped groove on the back surface of the driving rollers 66, 66 and the driven rollers 67, 67 are wound endlessly. .

  Further, as shown in FIGS. 10, 12 (a), 12 (b), 14, and 15, the left and right sides of the body are separated from the sorting frame 55 on the non-conveying action side (the lower side of the winding area) of the conveying belts 68 and 68. Left and right shafts 97 and 97 are respectively arranged toward the center in the direction, and a plurality of divided rollers 98... Having a large diameter portion 99 formed on the shafts 97 and 97 are axially attached. Further, by providing left and right cushion rollers 100, 100 for preventing the divided roller 98 from moving in the left-right direction on the left and right outer sides of the divided rollers 98, 98 located at both left and right outer ends, the conveying belts 68, 68 are provided. The tension rollers 69 and 69 are configured to be rotatable so as to prevent the belts 68 and 68 from slacking downward without diffusing water adhering to the belt.

  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.

Thus, left and right transport conveyors 70 and 70 are configured to transport the crop from the front side of the machine body to the rear side.
The driving rollers 66 and 66 and the driven rollers 67 and 67 are disposed in the winding regions of the outer end portions of the conveyor belts 68 and 68, respectively. Therefore, when a heavy object is placed on the conveyor belts 68 and 68, the conveyor belt. 68 and 68 can flex flexibly according to the weight.

  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.

  Further, 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 rollers 98, 98 located at the left and right outer ends, thereby making contact with the transport belt 68. Since the split rollers 98, 98 can be prevented from moving in the left-right direction at this time, the split rollers 98, 98 are prevented from moving water to the back side of the transport belt 68, and the transport belt 68 slips. Can be prevented.

  Also, instead of the tension rollers 69 shown in FIGS. 10, 12 (a), 12 (b), 14 and 15, as shown in FIG. 17, the left and right shafts 97, 97 have a plurality of recesses 103, 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 are formed. The rollers 69 may be configured.

  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.

Furthermore, the following tension rollers 69 shown in FIGS. 18A and 18B may be used.
A plurality of grooved portions 106a... Formed on the shafts 97 and 97 at substantially equal intervals are rotatably mounted with grooved rollers 106 having substantially the same left and right length as the left and right width of the conveyor belt 68, and the grooves 106a. An annular member 107 such as an O-ring having a larger diameter than the attached roller 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.

  10 and 14, 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 10, between the left and right of the left and right transport conveyors 70, 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 devices 75, 75 in the front row. A mountain-shaped separation plate 91 is provided in a front view or a rear view, and a plurality of collection shooters 93 are moved 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. A connecting handle 94 that connects the plurality of recovery shooters 93... And can be lifted by the operator by hand is disposed above and behind the recovery 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.
7, 8, 9, 10, 19 (a) and 19 (b) and 20 (a), (b), and (c), the conveyance end points of the left and right conveyance conveyors 70 and 70 are shown. Left and right mounting tables 96 for mounting a container 92 such as a box-shaped container or bag body for collecting non-standard carrots that are not selected because they are too large (4L or more) or too small (2S or less). 96 are arranged so as to be rotatable in the longitudinal direction of the body.

  Then, support brackets 108 and 108 having a “h” shape in a side view are attached between the conveyors 70 and 70 and the mounting tables 96 and 96 and on the rear end portion side of the machine body of the sorting frame 55, and are attached to the rear of the machine body. The scraper plates 109 and 109 for scraping water and foreign matters by the front end contacting the left and right conveying belts 68 and 68 on the upper portions of the support brackets 108 and 108 inclined downward are mounted on the mounting tables 96 and 96, respectively. It is attached to the storage containers 92 and 92 placed in a rearward downward inclination posture. Thereby, the sorting and conveying unit E is configured.

  The front end of the scraper plates 109, 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 are scraped off. If the scraper plates 109 and 109 are turned over, the blade surface that is hardly worn comes into contact with the conveying belts 68 and 68 when the scraper plates 109 and 109 are turned over. Therefore, the scraper plates 109 and 109 can be used until the opposite surface is completely worn out. This improves durability.

  In addition, scraper plates 109 and 109 that are inclined downward toward the rear of the machine body are provided behind the transfer terminal portions of the sorting conveyors 70 and 70, and the upper portions of the scraper plates 109 and 109 are flat and have a carrot of 3S or less upward. Carrots that are not subject to sorting (minimum carrots of 2S or less) discharged from the sorting conveyors 70 and 70 are formed by allowing them to pass through, for example, plate-shaped guides 109b and 109b having a slat-shaped guide with a left-right spacing of less than 10 mm. Since it can be set as the shooter which guides to the storage containers 92 and 92 mounted in the mounting bases 96 and 96, ginseng can be reliably discharged | emitted out of an apparatus and work efficiency improves.

  When the scraper plates 109 and 109 are made of a synthetic resin such as polyethylene generally used for food candy or candy letters, they can have appropriate elasticity and harmful components may adhere to carrots. Therefore, the safety of carrots is ensured.

  As shown in FIGS. 20A, 20B, and 20C, the scraper plates 109 and 109 are formed with long holes 109a and 109a that are long in the front-rear direction at equal intervals in the left-right direction, and are inclined downward. Screw holes 108a and 108a with screw grooves are formed in the upper portions of the support brackets 108 and 108 at the same left and right intervals as the long holes 109a and 109a.

  If the left and right intervals of the long holes 109a, 109a are the same as or slightly longer than the long side of the carrot of 2S or less, even if the scraper plates 109, 109 are attached to the support brackets 108, 108 with fixing members such as bolts and nuts, Since the carrot is prevented from coming into contact with the fixing member and being damaged, it is possible to prevent the carrot from being scraped by the impact of the contact and deteriorating 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, the upper end portion of the fixing member such as a bolt and nut for fixing the scraper plates 109 and 109 to the support brackets 108 and 108 does not protrude from the upper end portions of the scraper plates 109 and 109 (not shown) ), Large carrots of 4L or more are less likely to be damaged.

  Further, in order to attach the support brackets 108 and 108 to the sorting frame 55, round holes 108a for attaching fixing members such as bolts are formed inside the body of the support brackets 108 and 108, and the left and right sides of the support brackets 108 and 108 are formed outside the body. An arc-shaped long hole 108b that allows the inclination angle of the direction to be changed is formed.

  In the case of the above configuration, assuming that the upper end position of the long hole 108b is substantially horizontal with the position where the round hole 108a is formed, the inclined posture of the support brackets 108 and 108 in the left-right direction is from the horizontal state with respect to the transport conveyor 70. The adjustment can be made within a range until the conveyor conveyor 70 is inclined downward in the outer direction of the machine body, and the 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. 108 and 108 can be adjusted in a horizontal inclination direction from the horizontal state with respect to the conveyer 70 to a downward inclined position with respect to the conveyer 70 toward the outside of the machine body. The rotation can be restricted.

With the above configuration, the left and right transport conveyors 70 can be driven by the single drive motor 56, so that the number of parts is reduced, thereby reducing costs and saving resources.
Further, since the transfer speeds of the left and right transfer conveyors 70 and 70 are substantially the same, the efficiency of the left and right sorting operations can be made substantially the same, and the carrots are sequentially sorted by the left and right transfer conveyors 70 and 70. Efficiency is improved.

  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 area of the conveyor belts 68 and 68, the carrot taken over from the transfer device D falls onto the sorting conveyor 70. Since the cushion plate 73 absorbs the impact, the carrot is prevented from being damaged by the impact of the drop, and the commercial value of the carrot is improved.

  Furthermore, 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. This can improve the accuracy of carrot sorting.

  The cushion plates 73, 73 are arranged from the front end portions of the front slider plates 72, 72 to a substantially central position in the front-rear direction, and are not provided on the rear end side close to the weight sorting device 75, thereby providing a 3L size. Thus, it is possible to prevent a part of such a long and heavy carrot from being detected while the weight remains 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 weight detection plate 78 is bent downward at a right angle to form a right angle portion 78a, 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 left and right transport conveyors 70, 70 are inclined upward by about 0.5 to 1 degree from the outside of the machine body to the inside, the carrots can move toward the outside of the machine body of the transport conveyors 70, 70. It is possible to prevent the carrot from being moved from the transport conveyor 70 to the collection shooter 93 without being hit by the jumping device 84, improving the sorting accuracy, and eliminating the need for the operator 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 collection shooters 93 as the weight detecting device 75 and the jumping device 84 between the left and right of the left and right sorting conveyors 70, the carrot of the weight detected by the weight detecting device 75 is handled by the jumping device 84. It can be sent to the grade collection shooters 93...

  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.
The left and right placing tables 95 and 95 for placing the storage containers 92 for collecting non-standard carrots are provided at the conveying end portions of the left and right conveying conveyors 70 and 70, so that it is difficult to set sorting conditions. Since the carrot can be collected just by transporting it, the efficiency of the sorting work is improved.

  Further, since the mounting tables 95 and 95 are provided so as to be rotatable in the front-rear direction, when the sorting and conveying unit E is stored, the mounting tables 95 and 95 can be brought close to the machine body to shorten the front-rear width. Even if the space is small, it can be easily stored.

  Further, since the elongated holes 109a and 109a are formed in the scraper plates 109 and 109, the position where the scraper plates 109 and 109 are attached to the support brackets 108 and 108 can be adjusted in the front-rear direction. When there is a large amount of water, when the front end of the scraper plates 109 and 109 and the conveyor belts 68 and 68 are brought close to each other, water and contaminants are removed by the scraper plate 109, so that water and contaminants enter the back side of the conveyor belt 68 and slip. It is prevented. 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 and impurities on the conveyor belt 68, the front end of the scraper plates 109 and 109 and the conveyor belts 68 and 68 are slightly separated to reduce the contact amount, which is unnecessary for the sorting belts 68 and 68. Since the friction can be prevented, the sorting belts 68 and 68 are prevented from being damaged by the friction, and the durability is improved.

  Further, long holes 108b and 108b for mounting are formed inside or outside the body of the support brackets 108 and 108, and the support brackets 108 and 108 are horizontally mounted with the round holes 108a and 108a serving as pivot points. Since the posture can be changed from the posture to the downward inclined posture toward the outer side of the machine body, the scraper plates 109 and 109 can discharge the water and impurities scraped from the conveyor belts 68 and 68 to the outer side of the machine body. Water and other contaminants are prevented from entering the back side of the belts 68 and 68, the conveyor belt 68 is not bent at the weight detection position, and the carrot is selected by a lower grade, or the reaction that the conveyor belt 68 stops. Thus, the carrot does not move to the collection shooter 93 of a different grade, and the carrot sorting accuracy is improved.

  In addition, if the downward inclination angle of the scraper plates 109 and 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 plates 109 and 109 are not easily caught in the rotation of the conveyor belts 68 and 68. Therefore, the scraper plates 109 and 109 are not bent or bent during work, and the durability of the scraper plates 109 and 109 is improved.

Further, since it is not necessary to replace or reassemble the scraper plates 109, 109 that are damaged or detached during the work, the work efficiency is improved.
Further, when the angle at which the support brackets 108 and 108 are inclined downward toward the outer side of the machine body is set in a range of 2 to 5 degrees, the scraper plates 109 and 109 are used to store the carrots discharged from the sorting conveyors 70 and 70 into the storage containers 92 and 92. The water and impurities scraped off from the conveyor belts 68 and 68 can be moved to the outside of the machine body and discharged without impairing the function as a shooter that feeds to 92.

  As shown in FIGS. 21 to 24, a plurality of draining grooves 110... Are formed at predetermined intervals in the left-right direction on the surface side of the weight detection plate 78 constituting the weight detection device 75 in the longitudinal direction of the machine body. The draining grooves 110... Form a width (the conveyance direction upper side width w <b> 1 <the conveyance direction lower side width w <b> 2) that becomes wider from the conveyance direction upper side of the conveyance conveyor 70 toward the conveyance direction lower side. The vertical length increases from the upper side in the transport direction toward the lower side in the transport direction, that is, the groove is wider and deeper (transport direction upper side depth d1 <transport direction lower side depth d2). Specifically, the lateral width on the upper side in the conveyance direction of the draining groove 110 is 1 to 2 mm, the vertical length (groove depth) is 2 to 3 mm, and the lateral width on the lower side in the conveyance direction is 2.5 to 3 mm. The vertical length (groove depth) is 4 to 5 mm.

  Further, more draining grooves 110 are formed on the left and right inner sides of the weight detection plate 78 where the ginseng bounced by the jumping plate 88 moves to the recovery shooter 93 than on the left and right outer side of the body, that is, the side including the jumping plate 88. In other words, the left and right intervals between the draining grooves 110 formed on the left and right outer sides of the weight detection plate 78 are widened, and the left and right interval between the draining grooves 110 formed on the left and right inner sides of the weight detection plate 78 are narrowed. It is.

  Further, a drainage shooter 111 is provided on the front support arm 77a of the slider plate 76 to receive water that flows down from the lower side in the transport direction of the draining grooves 110 and drains it to the recovery shooter 93 side. The drainage shooter 111 has an end on the upper side in the transport direction up to the mounting position on the front support arm 77a below the weight detection plate 78, and an end on the lower side in the transport direction from the mounting position on the front support arm 77a. Is disposed below the slider plate 76 so as to have a downward inclined posture from the upper side in the transport direction toward the lower side, and the end on the lower side in the transport direction is bent toward the collection shooter 93 so that water is collected in the recovery shooter. It is set as the structure which flows down toward 93.

Alternatively, a terminal drainage shooter 111a that is inclined downward toward the collection shooter 93 side may be attached to the end portion on the lower side in the transport direction.
Further, the upper end position on the start end side of the drainage shooter 111 is located below the lower end portion of the weight detection plate 78 that is lowered by the weight of the carrots conveyed by the conveyance belts 68, 68, and interferes with the vertical movement of the weight detection plate 78. Do not place it.

The drain shooter 111 may be provided only on the left and right inner sides where water easily moves into the winding region of the conveyor belt 68 and water easily enters the draining grooves 110.
With the above configuration, the horizontal width of the drainage shooter 111 can be reduced to about half, so that the amount of resources for parts production can be reduced, and when the water moves a little, it falls to the recovery shooter 93. Therefore, it is difficult for water to remain in the drainage shooter 111, and the removal of water can be lightly wiped off or left to dry naturally, so that maintainability is improved.

  With the above-described configuration, even if water enters the winding region of the conveyor belt 68, the water passes through the plurality of draining grooves 110 formed in the weight detection plate 78, and from the upper side in the conveying direction to the lower side in the conveying direction. Since the forming and conveying belt 68 is stuck to the weight detecting plate 78 and stops moving, and the driving of the conveying conveyor 70 can be prevented from being disturbed, the carrot sorting operation is not stopped and the work efficiency is improved. In addition, it is possible to prevent the carrot from falling from the conveyor belt 68 and falling to the collection shooter 93 different from the original collection shooter 93 at the time of sudden stop.

  Further, it is possible to prevent the weight detecting plate 78 from moving down and not operating the jumping plate 88 even if the conveyor belt 68 is stuck to the weight detecting plate 78 and a carrot to be sorted passes, and the weight detecting plate 78 is prevented from operating. Is pushed down by the conveyor belt and prevents the jumping plate 88 from operating when ginseng lighter than the original weight to be sorted passes, reducing ginseng sorting due to false detection and improving sorting accuracy. To do.

  And the width of the draining groove 110 is configured to be wider toward the lower side in the transport direction, and the depth of the draining groove 110 is configured to be deeper toward the lower side in the transport direction, so that the water that has entered the draining groove 110 is moved to the lower side in the transport direction. Since it can be made to flow easily, water does not easily accumulate to the upper end portion of the draining groove 110, and the conveyance belt 68 is prevented from sticking to the weight detection plate 78, and the sorting accuracy is improved.

  Further, by forming the plurality of draining grooves 110 at intervals in the left-right direction, the contact area between the conveyance belt 68 and the weight detection plate 78 is reduced regardless of the presence or absence of water, and the conveyance belt 68 is reduced to the weight detection plate 78. Since the frictional resistance applied when passing above is weakened, the rotational speed of the conveyor belt 68 is difficult to reduce, so that the ginseng sorting work efficiency is improved and the sorting accuracy is improved.

  In addition, since the gap between the draining grooves 110 on the side of the recovery shooter 93 where the carrots bounced off the jumping plate 88 moves, that is, the left and right inner sides of the aircraft, is wider than the interval between the draining grooves 110 on the left and right outer sides of the aircraft, Water is reliably prevented from accumulating on the side where the transport belt 68 and the weight detection plate 78 come into contact with each other, so that the transport belt 68 is prevented from contacting the weight detection plate 78 and the This reduces the number of false detections and improves sorting accuracy.

  Further, the drainage shooter 111 for receiving and discharging water discharged from the draining grooves 110... Is provided below the slider plate 76 and the weight detection plate 78 so that the water discharged from the draining grooves 110. Since it can be prevented from splashing over here, the work time required for water removal is shortened and the labor of the worker is reduced. Improves.

  The drain shooter 111 is inclined downward toward the lower side in the transport direction and the end on the lower side in the transport direction is bent toward the collection shooter 93, so that the water received by the drain shooter 111 is recovered. Since it is discharged toward the shooter 93, it is possible to reduce the number of places where water is removed after the work is completed, so that maintainability is improved.

  Further, since water is supplied to the collection shooter 93, the carrots riding on the collection shooter 93 can easily slide downward, so that the carrots can be prevented from staying on the collection shooter 93, and the carrots can be separated from each other on the collection shooter 93. Is prevented from being damaged by contact, and the commercial value of the crop is improved.

  In addition, since water is supplied to the collected carrots, it is possible to prevent the carrots from drying out over time, so it is possible to prevent the carrots from drying too much and deteriorating the quality. Value is improved. The above effect is very effective when working for a long time in a well-ventilated place or a place with high temperature.

Furthermore, it is not necessary for the operator to manually recover the carrot remaining in the recovery shooter 93, and the labor of the operator is reduced.
Then, the start end side of the drainage shooter 111 is positioned below the upper end side in the transport direction with respect to the end portion on the lower side in the transport direction of the weight detection plate 78, so that the water that has entered the draining grooves 110. The drainage shooter 111 can collect water even if it falls down after turning around, so that it is possible to prevent water from being scattered to the far side of the sorting and conveying section E and to easily remove the water. As a result, maintainability is improved and corrosion and deterioration due to water are prevented, and durability is improved.

  Further, the upper end position on the start end side of the drainage shooter 111 is arranged below the lower end portion of the weight detection plate 78 in the lowered state, so that the drainage shooter 111 can be prevented from interfering with the lowering of the weight detection plate 78. Therefore, sorting of carrots is not hindered and sorting accuracy is improved.

  The drainage shooter 111 may be formed with a water flow groove 112 along the direction of drainage. Like the draining groove 110, the drainage shooter 111 is configured such that the width on the lower side in the conveyance direction becomes wider and the groove depth becomes deeper. Further, it is difficult for water to remain in the drainage shooter 111, and the labor required for the water removal work after the work is completed is reduced.

  Further, as shown in FIG. 25, water easily enters the winding region of the conveyor belt 68, and when the carrot passes, the drain groove is formed only on the left and right inner sides of the weight detection plate 78 where the conveyor belt 68 and the weight detection plate 78 come into contact. 110 ... may be formed.

In the above configuration, since the number of draining grooves 110 formed in the weight detection plate 78 is reduced, there are many portions where the thickness of the weight detection plate 78 does not change, and durability is improved.
Furthermore, since the number of steps for forming the draining groove 110 on the weight detecting plate 78 is reduced, the manufacturing cost of the weight detecting plate 78 on which the draining groove 110 is formed can be reduced, and the cost can be reduced.
