[Problems to be solved by the invention]
However, according to the configuration of Patent Document 1, the sorting process in the particle size sorting unit laterally supports and configures a sorting cylinder having a long length with a number of slit-shaped sorting holes formed in the outer periphery, and is driven to rotate in a fixed direction. Thereby, the supplied soybean grains are separated into those that leak from the sorting hole and those that do not. In addition, the surface of the soybean which is locked in the sorting hole in a layered manner in the sorting cylinder is easily damaged, which causes chipping. For this reason, even if it is possible to take out the sized product with a belt sorter with high accuracy, damaged particles are generated by the subsequent particle size sorting process.
[0005]
In some cases, damage to soybeans may occur during transportation from equipment to equipment. Therefore, it is better to avoid a transport mode in which the soybean itself is relatively loaded, for example, transport by an elevator.
In addition, sampling is performed by a voluntary testing device to check the content of high value-added particle sizes.However, it is only necessary to grasp the distribution of particle sizes and to judge the accuracy of particle size selection of the main line. However, improvements are still required.

The paper is discharged to the discharge conveyance device 54a, 54b or 54c.
On the other hand, in the case of the dust particle hopper 32, the upper and lower hoppers are displaced to the left and right, but the dust particles from the upper hopper are communicated with the lower dust particle tank by appropriate means so that the dust particles can be collected. The waste is discharged to the discharge conveying device 55 for dust particles that have been viewed.
[0039]
Since the particles are sorted into small, medium and large grains in advance and supplied to the belt sorter 23, the sized grains discharged from the belt sorter 23 have the same particle diameter, and therefore, are sorted out from the belt sorter. There is no need to perform a particle size sorting process on the particles.
The soybean grains discharged to the discharge conveying devices 54a, 54b, and 54c are supplied to the product tank 57a, 57b, or 57c in which the grain size to be accommodated is set in advance via the connection portion 59.

And then sequentially supplied to a wind separator 73 below the floor to remove the peeled skin, dust, and the like generated in the metal removal process, transport, and sorting process by wind sorting. After performing such a finishing process, it is supplied to the measuring tank 74 and weighed, and is used for each consignee or for confirming the shipping amount.
[0041]
At the time of shipment, a flexible container shipping form or a bulk shipment by vehicle can be selected.
In the above embodiment, the particle size sorting unit 3 is arranged on the top floor (third floor) of the building, and the belt sorter 23 is arranged on the lower floor. The transport of the soybeans to the sorting unit 4 is configured such that the supply transport device 21 in the form of a flight conveyor is placed sideways on the way, but is transported from the upper level to the lower level, without using a transport mode like an elevator. Sufficient soybean damage can be prevented as much as possible. In addition, the sizing tank 57 is formed on the first floor, and the conveyance from the belt sorting unit 4 also has a natural flow structure from the upper to the lower, so that damage to soybeans is reduced.
[0042]
Reference numeral 76 denotes a camera for observing the state of grain supply to the respective belt sorters 23 of the belt sorter 4 of the belt sorter 4 stacked in a bed shape of the belt sorter 4, and supplies soybean to a monitor (not shown). The configuration is such that the supply side of the sorting belt 25 near the section 28 is projected. The upper and lower two-stage sorting belts 25 are configured in the unit sorting unit 33, and the front, rear, left and right inclination angles α and β and other conditions are the same. The conditions for both the sorting belt and the lower-side sorting belt are constant, and if soybeans with the same particle size and other properties are supplied to this sorting belt, it is expected that the same sorting distribution will be obtained in the upper and lower parts. By monitoring the camera with the camera, it is possible to grasp the overall sorting state. Therefore, by monitoring the upper side of each of the unit sorting units 33 stacked in the above-mentioned bed type, it is possible to confirm the supply state of the selected soybeans in the entire belt sorter 23 and the diffusion of the soybeans to the belt surface, and thus to grasp the soybean clogging. . The camera image may be directly displayed on the monitor and monitored, or the image processing may be performed to detect the presence or absence of the sorted soybean, and the grain clogging may be automatically detected.
[0043]
A forward / reverse motor 79 is mounted on the screw shaft 78 so that the mounting base 77 can move up and down along the vertical screw shaft 78 so that the camera position can be finely adjusted vertically. Therefore, an appropriate position can be selected while adjusting in the up-down direction because a wide range is measured over the up-down range. Instead of this vertical movement, the camera 76 may be configured to be swingable up and down or up and down and left and right with respect to the mounting machine base 77 so as to be a wide range of measurement over the up and down range.
[0044]
FIG. 8 shows a different example of the sorting belt of the belt sorting machine 23. The selection belt 80 is formed of a magnetic component, and the metal is carried around to the inclined high side along with the selection belt 80 together with the debris while being attracted by the magnetic force. Is separated from the surface of the belt 80 by the scraping action of the soybeans, and is collected in the collection box 83 viewed from below.
