Since it becomes easy to sort, the orientation of the crops is aligned in a certain direction and multiple crops do not overlap, reducing the missorting of the left and right sorting devices, and preventing re-sorting the missorted crops manually. Therefore, the labor of the operator is reduced.

  Further, since the crops are placed in the vicinity of the conveyance start end of the left / right alignment conveyance device C, the number of crops sent back from the left / right transfer member 34 to the storage unit can be reduced, so that work efficiency is improved. And since the surface of the separating member 22 becomes a curved surface, the crop is prevented from being damaged by the impact of dropping on the separating member 22, so that the quality of the crop is improved. In addition, if the separating member is formed of an elastic body, the effect of preventing damage is further improved.

  According to the invention of claim 4, in addition to the effect of the invention of claim 1, the separation member 22 is configured to be adjustable in the front-rear position, so that the discharge member 11 and the separation member according to the diameter and length of the crop. 22 is adjustable, the crop is moved on the separating member 22 because the interval is too wide, and the separation member 22 is provided in the middle of the left-right aligned conveying device or on the conveying terminal portion. Since it is prevented that the crops are clogged between the discharge member 11 and the separation member 22 due to the interval being too narrow, work efficiency is improved.

  According to the invention of claim 5, in addition to the effect of the invention of claim 1, the length (L1) in the front-rear direction of the left and right first aligned transport device C1 is set to the length in the front-rear direction of the left and right second aligned transport device C2. Since it is configured to be longer than (L2), it is possible to lengthen the time during which the crop distributed from the separating member 22 or the distributing member 21 is placed on the left and right first aligned transport device C1, so that the transport posture of the crop is As a result, the crops are put into the left and right sorting device D one by one in the same posture, and the sorting accuracy of the crops is improved.

In addition, since the transport speed (S2) of the left and right second aligned transport apparatus C2 is made faster than the transport speed (S1) of the left and right first aligned transport apparatus C1, the left and right first aligned transport apparatus C1 to the left and right second aligned transport apparatus. Since the interval between the crops can be widened when the crops are handed over to C2, the crops are transferred one by one to the left and right aligning device C to prevent erroneous sorting, and the sorting accuracy is improved.
If the conveyance speed of the left / right sorting device D is made faster than the sorting speed of the left / right second alignment device C2, the interval between the crops is increased even when the crop is transferred from the left / right second alignment device C2 to the left / right sorting device D. , Mis-sorting is further prevented and sorting accuracy is improved.

Further, the left and right second driven belts 25 and 25b and the left and right second drive pulleys 25a and 25a are wound endlessly on the left and right second alignment belts 26 and 26, each having a concave cross section. It is assumed to be a two-alignment conveying device (sometimes referred to as a second aligned conveying conveyor) C2.

  A mountain-shaped sorting member 21 is provided on the inner side of the pair of left and right first alignment belts 19, 19 having a ridge line in the crop conveying direction and a downward inclined surface in the left and right direction as viewed from the rear. Further, as described in the upper left round frame of FIG. 1, a protruding portion 21a having a mountain-shaped cross section is provided at the central ridge line portion of the sorting member 21 in the crop conveying direction, and a separating member is provided at the front upper portion of the protruding portion 21a. 22, the crop that falls from the takeover shooter 11 toward the sorting member 21 is distributed by the separating member 22 on the sorting member 21 to the left or right descending inclined surface of the sorting member 21 and dropped. Falling crops are taken over by the left and right first alignment belts 19 and 19.

  The separation member 22 is arranged in a horizontal posture with respect to the distribution member 21 or in an inclined posture that is positioned higher toward the rear side of the machine body, and the height of the rear end portion of the separation member 22 is higher than the upper end portion of the distribution member 21. Located on the distribution member 21. The length of the separating member 22 in the conveying direction is about one root vegetable such as carrot (about 50 mm). If the length of the separating member 22 is longer than that, there is a risk that the crop will remain on the separating member 22, and conversely, if the length is shorter than that, the separating member 22 before the crop is distributed to the left and right by the separating member 22. Therefore, there is a problem that a large number of the sliding members 21 move to the sorting member 21 and slide on the central projecting portion 21a of the sorting member 21. In addition, the upper surface of the separation member 22 has an inclination angle with respect to a horizontal plane such as a floor, as viewed from the side of the crop alignment apparatus according to the present embodiment. When the inclined surface is attached, the separation member 22 can reduce the moving speed of the crop, so that the crop can easily fall to the left or right transport conveyor side of the first aligned transport conveyor C1. The separation effect is improved.

  Further, it is desirable that the separation member 22 is made of an elastic body, and absorbs an impact when the crop falls from the pumping and conveying apparatus B by the elastic body so that the crop is not damaged. Note that the separation member 22 may be formed of a metal plate, a hard plastic plate, or the like, and an elastic body such as rubber or soft resin may be mounted on the surface thereof.

  As shown in the rear view of the main part of the aligning and conveying apparatus C in the upper left round frame in FIG. 1, the first aligning and conveying conveyors 19 and 19 and the second aligning and conveying conveyors 26 and 26 include a separating member 22 and a distributing member 21. The crops distributed to the left and right are supplied and aligned by the rear alignment device D.

  A motor 13 having sprockets 14a and 14b attached to an outer drive shaft 13a is placed on the frame 1 below the takeover shooter 11 from the lower part of the drive roller 7b, and the sprocket 15 integrated with the shaft 6b A chain 23 is wound endlessly between the sprocket 14b and used as a drive source for the chains 9 and 9 via the shaft 6b.

  In addition, a first counter sprocket 31 pivotally supported by a shaft 30 supported at the front ends of the alignment frames 16 and 16 is provided above the sprockets 14a and 14b, and the motor 13 passing through the sprocket 14a is provided. The driving force drives the sprocket 28 integral with the shaft 17a via the chain 29, the first counter sprocket 31, and the chain 32, and simultaneously drives the first driving pulleys 18a and 18a. The first driven pulleys 18b and 18b The first transmission sprocket 33 is attached to the center of the shaft 17b, and the second transmission sprocket 35 is attached to the center of the drive shaft 24a to which the second drive pulleys 25a and 25a are attached. Chain provided between the first transmission sprocket 33 and the second transmission sprocket 35 Second driving pulley 25a, 25a are driven by a 6. At this time, the conveyance speed Bm / sec of the left and right second alignment belts 26 and 26 is set faster than the conveyance speed Am / sec of the left and right first alignment belts 19 and 19.

  As shown in FIGS. 1 and 2, the rear side of the first and second left and right alignment belts 19 and 19, which is below the sorting member 21 and has a concave cross section, and between the left and right second alignment belts 26 and 26. A pair of crop drop guides 40, 40 that are inclined downward toward the left and right outside are arranged.

  Further, the crop conveyance start end side of the left and right return shooters 34, 34 are respectively arranged below the lower ends of the pair of crop drop guides 40, 40, and the crop conveyance end portion side of the return shooters 34, 34 is the storage unit A side. The hopper 2 is supported on the upper opening portion wall surface. Thus, the aligning and conveying apparatus C includes the separating member 22, the distributing member 21, the first aligning belts 19 and 19 (left and right first aligning conveyor C1), the second aligning belts 26 and 26 (left and right second aligning conveyor C2), crops. It comprises drop guides 40, 40 and left and right return shooters 34, 34.

  By arranging the sorting member 21 in the aligning / conveying device C, among the crops taken over by the aligning / conveying device C, the crops transported near the center of the aligning / conveying device C are not separated in the left-right direction. It moves to the crop drop guides 40, 40 and falls from the left and right crop drop guides 40, 40 to the left and right return shooters 34, 34, or the rear end of the first alignment belts 19, 19 (left and right first alignment conveyor C1) in the transport direction. The crops fall on the side and the second alignment belts 26 and 26 (left and right second alignment conveyor C2), and the crops arranged in a line on the left and right first alignment conveyor C1 and left and right second alignment conveyor C2 are flipped and aligned. Since the state is prevented from being disturbed, the crops are prevented from being damaged by the collision between the crops, the quality of the crops is improved, and the left and right return shooters 34, 4 crops back to the reservoir portion A is reduced from improved transport working efficiency of the crop. In addition, since the crop alignment posture is stabilized, the pair of left and right sorting devices D are handed over in a posture in which the crops are arranged one by one, so the number of crops that are misselected by the left and right sorting devices D is reduced and the crops are misselected manually. Therefore, it is possible to reduce the labor of workers by preventing re-sorting of the crops.

  1, the left and right return shooters 34, 34 are attached to the left and right sides of the aligning / conveying device C, so that the left and right first aligning conveyor C1 and the left and right second aligning conveyor C2 are mounted. The return shooters 34 and 34 can take over the crops that have not been or have been dropped from the first and second alignment conveyors C1 and C2 in the middle of the alignment conveyance from the crop drop guides 40 and 40, and can be quickly returned to the storage unit A. As a result, the work efficiency can be improved, and the alignment work and the sorting work can be automated.

  In addition, the width of the left and right first alignment belts 19 and 19 and the left and right second alignment belts 26 and 26 in the direction perpendicular to the conveying direction is about the same as the average diameter of the crop or smaller than the average diameter of the crop. Since the crops placed on the left and right first alignment belts 19 and 19 and the central portions of the left and right second alignment belts 26 and 26 fall to the left and right sides of the transport endless belt, the crops are arranged one by one in the left and right sorting device D. Since it is inherited in the posture, the number of crops that are misselected by the left and right sorting device D is reduced, and it is prevented that the misselected crops are manually sorted, thereby reducing the labor of the operator.

  Also, if the transport speed of the second alignment transport conveyor C2 is set faster than the transport speed of the first alignment transport conveyor C1, when the crop is handed over from the first alignment transport conveyor C1 to the second alignment transport conveyor C2, due to the speed difference. Since a certain back-and-forth interval is generated between the crops, the crops are handed over to the left and right sorting device D in a state of having a certain spacing in the front and rear direction with the postures arranged one by one. And the labor of the operator is reduced by preventing re-sorting of mis-sorted crops manually.

  Further, by making the length of the first alignment transport conveyor C1 in the transport direction longer than the length of the second alignment transport conveyor C2 in the transport direction, the crop transported from the pumping device 10 is transferred onto the first alignment transport conveyor C1. Since the time during which the crop is transported becomes longer and the posture of the crop is transferred to the second aligned transport conveyor C2, the crop is easily transferred from the first aligned transport conveyor C1 to the second aligned transport conveyor C2. In addition, since the front-to-back distance between the crops generated during the transfer is substantially uniform, the number of crops that are misselected by the left and right sorting device D is reduced, and the workers are prevented from re-sorting the misselected crops manually. The effort is reduced.

  Then, crop drop guides 40 and 40 for guiding crops dropped from the first alignment belts 19 and 19 and the second alignment belts 26 and 26 are attached to the left and right, and the left and right return shooters 34 below the left and right crop drop guides 40 and 40. , 35 is attached, the crops dropped from the aligning and conveying apparatus C are automatically sent back to the storage section A, so that the work efficiency is improved.

  As shown in the overall side view of the crop conveying device in FIG. 5, the separating member 22 for separating the crops to the left and right is arranged not at the top of the mountain-shaped sorting member 21 but at the terminal end (exit) of the pumping conveying device B. You may make it attach directly under the takeover shooter 11. FIG. In this case, the positional relationship between the takeover shooter 11 and the separating member 22 does not change even if the arrangement position and the inclination angle of the takeover shooter 11 at the outlet of the pumping and conveying apparatus B are changed. Can respond.

  The separation member 22 has a base 22a attached to the lower end of the takeover shooter 11, a cylindrical rod 22b attached to the rear side of the base 22a in the transport direction, and the tip of the cylindrical rod 22b being a sorting member. It is set as the structure attached so that the front side of 21 may overlap.

  The separation plate 43 is configured to move up and down inside guide frames 44 provided on both front and rear sides thereof, and a slide frame 45 integrated with the separation plate 43 extends in the vertical direction below the separation plate 43. The lower end of the slide frame 45 is in contact with a cam roller 48 provided at the tip of a shaft 47 extending in the horizontal direction. The contact surface side of the cam roller 48 with respect to the slide frame 45 is elliptical, and the bevel gear 49 provided at the other end of the shaft 47 meshes with the bevel gear 50 provided at the drive shaft of the motor 13. When the cam roller 48 is rotated by this, the slide frame 45 with which the cam roller 48 abuts moves up and down while abutting against the cam surface of the cam roller 48, whereby the separation plate 43 moves up and down. Further, since the top portion of the guide frame 44 is disposed below the upper surface of the sorting member 21, the guide frame 44 does not hinder the conveyance of the crop on the sorting member 21.

  The separation plate 43 has a "<" shape in plan view, and is attached to the sorting member 21 so that a bent portion with a "<" shape is disposed on the upstream side of the conveyance, thereby reducing the conveyance resistance of the crop. In addition, both ends of the “ku” character are rounded to prevent the crop from being damaged.

  Further, the upper surface of the separation plate 43 is textured, and a brake is applied by applying resistance to a crop that is going to get over the upper surface of the separation plate 43 so as not to slip. Further, the length of the upper surface portion of the grained separation plate 43 is about half the length of the crop, and even if the crop is placed on the upper surface of the separation plate 43, the first alignment belt 19, It drops on the sorting member 21 toward 19. Further, the embossing may be performed only on the first half of the upper surface of the separation plate 43, and the latter half of the upper surface of the separation plate 43 may not be embossed so as not to cause crop conveyance resistance.

In addition, the side surface of the separation plate 43, which is a part that the crops often hit during transportation, is composed of a soft material or a member provided with a soft film on the surface.
When the vertical position of the separation plate 43 is set by the rotation of the motor 13, the height of the separation plate 43 is set, and the crop is not slid directly to the second alignment belts 26 and 26, but is swung toward the first alignment belts 19 and 19. It falls on the dividing member 21.

  FIG. 9 is a drive system diagram of the conveyor drive system and the separation plate 43 of the crop aligning apparatus shown in FIGS. The timing at which the separation plate 43 jumps upward from the upper surface of the sorting member 21 is linked to the conveyance speed of the pumping conveyance device B, so that the separation plate 43 is also configured to enhance the right and left sorting function of the crop.

  Furthermore, the moving speed of the crops riding on the separating plate 43 is set by setting the starting end side of the separating plate 43 to be lower than the terminating end side and the central portion so that the upper surface of the separating plate 43 has a rearwardly inclined posture. Therefore, the crop easily falls to the left or right conveyance start end side of the first aligned conveyance conveyor C1, and the crop separation effect is improved.

  10 and 11 are a side view and a plan view, respectively, of a crop aligning apparatus according to another embodiment of the present invention. As shown in these drawings, the sorting member 21 of the present embodiment is divided in half into a front sorting member 21b and a rear sorting member 21c, and the rear sorting member 21c is made higher than the front sorting member 21b, A separation member 22 is placed on the front side of the sorting member 21c.

  Since the front sorting member 21b at the position where the crop falls from the pumping and conveying apparatus B is lower than the rear sorting member 21c, it becomes difficult for the crop after dropping to ride on the rear sorting member 21c. It is reliably returned to (left and right first alignment conveyor C1). Further, since the separation member 22 is placed on the front side of the rear distribution member 21c, the separation member 22 reliably returns the crop to the first alignment belts 19 and 19. With these configurations, the crops returned from the left and right return shooters 34, 34 to the storage section A are reduced, and the work efficiency is improved as compared with the prior art.

  Further, the length of the front distributing member 21b is appropriately about 50 to 80 mm. If it becomes longer than this, crops such as carrots move on the sorting member 21 and fall to the middle of the left and right first aligned transport device C or to the transport end portion, and the effect of providing the sorting member 21 is lost. Further, if the length of the front sorting member 21b is shorter than this, when a crop having an average diameter (about 50 mm) or more is thrown in substantially perpendicular to the conveying direction, the takeover shooter 11 and the front shaking are placed. There is a risk that crops will be clogged with the separating member 21b. Furthermore, although the average length of the crop is about 200 mm, when the crop enters a position substantially parallel to the conveyance direction, the crop is clogged between the takeover shooter 11 and the front sorting member 21b. It is distributed to the left or right by the distribution member 21 before.

  FIG. 12 and FIG. 13 show a side view and a plan view of the crop aligning device, respectively. The rotatable cylindrical separation rollers 50 and 50 are arranged at an inclination angle of from 5 ° to 5 °, and more preferably, the gap between the pair of separation rollers 50 and 50 is arranged so that there is no gap. . FIG. 14 is a drive system diagram for rotating the separation rollers 50 and 50 by the motor 13.

  Since the pair of separation rollers 50 and 50 are arranged with a gap of about 120 to 150 mm from the terminal end of the pumping and conveying apparatus B to the side surfaces of the separation rollers 50 and 50, the crop is clogged around the separation rollers 50 and 50. The first alignment belt can be prevented from being damaged even if the crops falling from the end of the pumping and conveying apparatus B touch the separation rollers 50 and 50 because the side wall surfaces of the separation rollers 50 and 50 are rotating. 19 and 19 (left and right first alignment conveyor C1) falls. Further, the upper surfaces of the separation rollers 50 and 50 are subjected to graining processing to give resistance to the fall of the crop, and the side surfaces are made of a soft material that makes the crop slip easily.

  The separation rollers 50 and 50 are operated from the motor 13 via a bevel gear mechanism, and the rotation timing of the separation rollers 50 and 50 is rotated once by one pitch of the roller 10a of the pumping and conveying apparatus B, so that the separation rollers 50 and 50 are separated. By rotating the rollers 50, 50 and the roller 10a of the draw-up conveying device B, the crop can be smoothly conveyed. Further, when a vibrator is provided on the rotation shafts 50a and 50a of the separation rollers 50 and 50, the separation rollers 50 and 50 vibrate and the crops are not caught.

  In addition, a gap of about 50 mm, which is approximately the same as the average diameter of the crop, is provided between the lower surface of the separation rollers 50 and 50 and the upper surface of the sorting member 21, so that the first conveying conveyer C1 aligns and conveys it. This prevents the crops from coming into contact with the separation rollers 50 and 50 and falling from the first aligning / conveying conveyor C1, so that the aligning / conveying is carried out stably and the storage part A from the left and right return shooters 34, 34 is performed. The work efficiency is improved because fewer crops are returned to.

  According to the crop aligning device of the present invention, it is possible to select so that the crop can be collected on either the left or right side orthogonal to the conveying direction, so that a compact crop aligning facility can be arranged indoors as desired by the operator. It can be.
