Abstract

PURPOSE:To effectively and completely discharge the second screened grains which are screened by a netted screening cylinder while being lifted by a grain lifting cylinder in the vertical type grain screening machine and fall within a screening chamber to a second screening port. CONSTITUTION:This vertical type grain screening machine is internally equipped with the grain lifting cylinder 3 having spirals 2 on its outer periphery within the netted screening cylinder 1 erected in the screening chamber A and is so constituted that the grains can be finely screened while the grains are lifted between these cylinders. Plural scraping plates 6 are respectively erected apart circumferentially spaced intervals above an annular partition disk 5 fixed to the outer peripheral part of a grain guiding cylindrical body 1a engaged with the netted screening cylinder 1 and rotated in the lower position of the screening chamber A. An annular inclined disk 7 inclining low from the inner peripheral side to the outer peripheral side is mounted above the partition disk 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a second grain discharging device for a vertical grain sorter capable of discharging all the second grain selected from a mesh sorting cylinder and falling in the sorting chamber to the second mouth.

[0002]

2. Description of the Related Art Conventionally, in a vertical grain sorter constructed so that a mesh-shaped sorting cylinder erected in a sorting chamber is internally equipped with a fried grain barrel having a helix on its outer periphery and the grains can be carefully selected while lifting the space between them. As disclosed in Japanese Patent Application Laid-Open No. 2-273117, the second item that is sorted by the reticulated sorting cylinder and falls in the sorting chamber falls on the partition disc and is discharged to the second port by the scraping plate. It has become.

[0003]

However, as seen in the above-mentioned publication, since the partition disc is horizontal, the inner peripheral side of the partition disc, which is closer to the outer peripheral surface side of the mesh sorting cylinder, is There is a problem that a large amount of No. 2 remains in the machine over the entire circumference because the No. 2 remains and cannot be discharged to No. 2.

[0004]

DISCLOSURE OF THE INVENTION The present invention has been devised to solve such a problem and to effectively discharge the second product without leaving it. A plurality of scraping plates are erected at respective intervals in the circumferential direction above the annular partition disk fixedly mounted on the outer peripheral portion of the engaged and rotating grain guide cylinder, and the partition disk The upper part is configured by mounting an annular inclined disc that inclines low from the inner peripheral side to the outer peripheral side, and the inner peripheral edge of the inclined disc is in contact with the outer peripheral surface of the reticulated sorting cylinder and the inclined disc The outer peripheral edge is formed so as to be in contact with the outer peripheral edge of the partition disk, the upper edge of each scraping plate is formed to be horizontal above the inclined disk, and each scraping plate is formed on the inclined disk. Form a plurality of grooves that can be fitted, and secure each scraping plate to the inclined disk and mesh. Sorting cylinder is constructed by engaging the respective scrape-out plates.

[0005]

Therefore, the inclined disc can be easily attached above the partition disc, and the second object falling in the sorting chamber after being sorted by the reticulated sorting cylinder while lifting the grains by the lifting grain cylinder is the inclined circle. As it falls onto the plate, the entire amount is effectively discharged to the No. 2 outlet without remaining as in the conventional case while flowing down on the inclined disc as it is to the outer peripheral side.

EXAMPLE FIG. 2 is a cross-sectional view schematically showing a vertical grain sorter, in which a fried grain barrel 3 having a spiral 2 on the outer peripheral surface is erected inside a mesh sorting barrel 1 erected in a sorting chamber A. The lower part 3a of the fried cylinder 3 is attached to the granule cylinder 10 communicating with the supply hopper 9.
Is equipped with a grain guiding cylinder 1a that engages with the lower part of the reticulated sorting cylinder 1, and each guiding vane 11 is mounted on the outer peripheral surface of the grain guiding cylinder 1a and the lower peripheral surface Forms a plurality of grain guide ports 12, and allows the mesh selection cylinder 1, the grain guide cylinder 1a, and the fried cylinder 3 to be rotatably driven by a lower motor 13, respectively, and the upper end of the mesh selection cylinder 1 Each side of the outer peripheral surface is provided with each scraping blade 16 of good rice and is constructed in the same manner as the conventional structure.

The upper end of the grain guide cylinder 1a is fitted inside the lower end of the reticulated sorting cylinder 1 with a packing 17 interposed between the mesh guide cylinder 1a and the outer periphery of the grain guide cylinder 1a. Outer edge 5a
Is fitted to the peripheral wall 18 at the lower part of the sorting chamber A and has a horizontal annular partition disc 5, and an upright edge portion 5b on the inner peripheral side thereof is fitted between the reticulated sorting cylinder 1 and the grain guiding cylinder 1a. And fixed to the upper surface of the annular partition disc 5 with respective vertical grooves (not shown) formed at the lower end of the reticulated sorting cylinder 1 which are slightly shorter than the disc 5 in the radial direction. The four quadrangular scraping plates 6 are set up at four equally spaced positions, and a packing 20 is interposed between the partition plate 19 above the upper end of the grain receiving cylinder 10 and the partition disc 5. An opening 4a communicating with the No. 2 opening 4 is formed in a part of the peripheral wall 18 facing the partition disk 5, and the upper part of the partition disk 5 is lowered from the inner peripheral side to the outer peripheral side. A slanting annular slanting disc 7 is mounted, and the slanting disc 7
The inner peripheral edge 7a of the inclined disc 7 is formed so as to be close to the outer peripheral surface of the reticulated sorting cylinder 1, and the outer peripheral edge 7b of the inclined disc 7 is in contact with the outer peripheral edge 5a of the partition disc 5, and as shown in FIG. Four grooves 8 that can be fitted into each scraping plate 6 are formed on the scraping plate 7, and the upper edge 6a of each scraping plate 6 is attached and configured so as to be horizontal above the inclined circular plate 7.

Alternatively, each scraping plate 6 may be fixedly mounted on the inclined circular plate 7 so that the lower part of the mesh-like selection cylinder 1 can be engaged with each scraping plate 6, and the scraping plate 6 can be mounted on the partition circular plate 5. it can.

Therefore, the slanted disc 7 can be easily installed above the partition disc 5, and the slanted disc 7 is sorted by the reticulated sorting cylinder 1 while being fried by the fried barrel 3 and drops in the sorting chamber A. When the second product such as scrap rice falls on the inclined disc 7, it will flow down on the inclined disc 7 as it is to the outer peripheral side as shown by the arrow in FIG. The total amount of each scraping plate 6 is effectively discharged to the No. 2 port 4.

[0010]

As described above, according to the present invention, the inclined circular plate 7 can be easily mounted above the partition circular plate 5,
The second product, which is sorted by the reticulated sorting cylinder 1 and drops in the sorting chamber A while being fried by the fried barrel 3, falls on the inclined disc 7, and the outer periphery of the inclined disc 7 remains unchanged. While flowing down to the side, the whole amount will be effectively discharged to the No. 2 opening 4 without remaining as in the conventional case, and the discharging performance from the partition disk 5 can be further improved.
It has a feature that it can be suitably implemented with a simple structure.
