Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an agricultural product sorting device that sorts oval spherical agricultural products such as cherry tomatoes based on their shape.

[Description of prior art]

A conventional agricultural product sorting device of this type has a required number of sorting tubes installed on a frame in a substantially horizontal direction with their axes parallel to each other, and the sorting tubes are rotatable in the circumferential direction with respect to the frame. A movable plate is horizontally installed between these sorting tubes and the movable plate is placed above the axis of the sorting tube, and a through hole of an appropriate diameter is formed in the side wall of the sorting tube. The movable plate and the outer wall surface of the sorting cylinder form a path for moving agricultural products, and a receiving container is installed inside the sorting cylinder, and the agricultural products can be sorted by boring the Only when the holes are smaller than the through holes of the agricultural products sorting tube rolling along the moving path, such agricultural products are allowed to fall into the inside of the sorting tube and are sorted.

[Problems with conventional technology]

However, as shown in FIG.
3,... were perfect circles, so agricultural products G shaped like an oval sphere (see Figure 3) could only pass through when entering the through hole 3 of the sorting tube 1 from the long axis direction, making it extremely difficult to sort. It was difficult. In particular, since the oval spherical produce G rolls on the movable plate with its major axis as the axis of rotation,
As a result, the sorting efficiency was further reduced.

In addition, the outer wall surface of the sorting cylinder 1 in this agricultural product sorting device constitutes a movement path for agricultural products, and agricultural products G having a larger diameter than the through hole 3 are placed in the through hole 3 while moving through the sorting cylinder 1. It moves as it rotates and is carried to the next moving plate, and eventually to the next sorting tube 1 (with a larger diameter through hole 3). At this time, in the case of the conventional agricultural product sorting device, since the through hole 3 of the sorting tube 1 was a perfect circle, it was difficult to hold the agricultural product G (see Fig. 3), which was shaped like an oval sphere. , the oval spherical produce G rolls on the movable plate with the long axis direction as the axis of rotation, so that the through hole 3 of the sorting cylinder 1 is
As a result, the movement efficiency of the agricultural products G on the agricultural products movement route is reduced, and the efficiency of sorting the agricultural products G is reduced.

[Means for solving the above problems]

This invention was made to eliminate the above-mentioned drawbacks, and its configuration is as follows: A required number of sorting tubes are installed on a frame in a substantially horizontal direction with their axes parallel to each other, and the sorting tubes are mounted on the frame. a movable plate is installed in a horizontal state between the sorting cylinders, and the movable plate is arranged above the axis of the sorting cylinder; A through hole of an appropriate diameter is bored in the side wall of the sorting tube to enable the sorting of agricultural products, and the movable plate and the outer wall surface of the sorting tube constitute a path for moving the produce; The agricultural product sorting device is equipped with a receiving container, characterized in that the through hole of the sorting tube is formed in the shape of a long hole having a long diameter in the axial direction of the sorting tube.

[Effect of idea]

Since the agricultural product sorting device according to this invention is configured as described above, that is, the through hole of the sorting tube is formed in the shape of a long hole having a long diameter in the axial direction of the sorting tube, so that agricultural products with an oval spherical shape can be collected. Even if there are particles, they can enter the through hole of the sorting cylinder from all directions (minor axis direction and major axis direction), and can be efficiently sorted by size.

In addition, in this agricultural product sorting device, since the through hole of the sorting tube is formed in the shape of a long hole having a major axis in the axial direction of the sorting tube, it is easy to lock the oval spherical agricultural products, especially in the major axis direction. The oval spherical agricultural products rolling on the movable plate with the movable plate as the rotation axis can be very easily stopped.

[Explanation of Examples]

Hereinafter, an embodiment of this invention will be described based on FIGS. 1 to 3.

In FIG. 1, 11 is a frame of the produce sorting device S, and this frame 11 has a movable plate 1.
3, 13, . . . are installed at predetermined intervals. These movable plates 13, 13, . . . are passages through which agricultural products G to be sorted move while rolling. 15 is a storage box, which is installed on the frame 11.
This storage box 15 is a place where agricultural products G to be supplied to the movement path 13 are temporarily stored.

Next, 17, 17, . . . are selection tubes, which are placed on the support rotating shafts 18, 18 and are rotatable to the frame 11 with their upper ends protruding between the movable plates 13, 13, . It is installed in The selection cylinders 17, 17, . That is, the outer wall surface of the selection tube 17 together with the moving plate 13 constitutes the agricultural product moving path of the present invention. Moreover, as shown in FIG. 2, this selection tube 17 has a tube body 1 made of synthetic resin.
7a and auxiliary frames 17b, 17b fitted into openings at both ends of the cylinder body 17a.
A long hole-shaped through hole 19 having a long diameter in the axial direction is formed in the hole. Then, this sorting tube 17 rotates clockwise (in FIG. 1) while
The agricultural products G having a diameter smaller than that of the through hole 19 are dropped into the inside of the selection cylinder 17 to be sorted according to size, and the agricultural products G having a diameter larger than the diameter of the through hole 19 are placed on the open end of the through hole 19. and convey it to the downstream moving plate 13. Note that the size of the through hole 19 increases as the distance from the storage box 15 increases.

21, 21, ... are driving rotating shafts, and the sorting cylinder 1
It is pivotally supported by the frame 11 while being in contact with the inner wall surface of the frame 7 . This driving rotation shaft 21 is a motor 23
The rotary motion is transmitted to the sorting cylinder 17.

Note that 25, 25, . . . are receiving containers for accommodating the agricultural products G sorted by the sorting tube 17, and are installed inside the sorting tube 17.

In this device, when sorting the agricultural products G, first, the selection tube 17 is rotated clockwise (in FIG. 1) by driving the motor 23. Then, the agricultural products G are pushed out from the storage box 15 in the direction of the moving plate 13. Then, the first selection tube 1
7 (the leftmost one in FIG. 1), if this diameter is smaller than the diameter of the through hole 19, the agricultural product G passes through the through hole 19 and falls into the receiving container 25. On the other hand, when the diameter of the produce G is larger than the diameter of the through hole 19, the produce G is carried to the downstream moving plate 13 while being placed on the open end of the through hole 19. Then, the transported agricultural products G are processed in the second selection tube (the second one from the left end in FIG. 1, and has a larger through hole diameter than the first selection tube) in the selection tube 17. subject to similar processing methods. In this way, agricultural products G are sorted out into larger diameter ones as they move away from the storage box 15, and eventually all the agricultural products G are sorted based on their shape.
