Abstract

PURPOSE:To enhance workability for the mounting and detachment of a sorting net body by providing a grain guide cylinder having a guide blade provided thereto in a wound state and a grain receiving cylinder to the lower part of a shell body. CONSTITUTION:Unsorted grains are sent into a grain receiving cylinder 60 from a supply hopper 14 and pushed down by the guide blade 55 of a grain guide cylinder 50 to be introduced into the cylinder 50 by a grain guide port 54. The grains are scraped up by the spiral blade 32 of a grain lift spiral body 30 to be scattered to the inner surface of a sorting net body 40 and small grains pass through the small holes 41 of the sorting net body 40 to be sorted. Good grains are sent upwardly to fall in a good grain guide trough 24b and scraped out by a scraping-out blade 45 to be sent to a storage tank 13. The small grains fall downwardly in the outside of the sorting net body 40 to fall on the partition disc 52 of the grain guide cylinder 50 and sent to the rear opening of a small grain discharge pipe 15 to be discharged to the outside. By this method, the replacing work of the sorting net body can be made easy.

Description

Detailed Description of the Invention "Industrial Application Field" The present invention provides a method for erecting and accommodating a sorting net body which is rotatably driven and a grain frying spiral body which rotates within the sorting net body in a vertically elongated shell. The present invention also relates to a vertical type 5a sorting machine in which grains are fried by a grain lifting spiral and small grains are sorted by passing through small holes in a sorting net.

There is one disclosed in Japanese Patent No. 27871.

That is, the publication states that an opening through which the sorting net can be inserted is provided at the upper end of the shell, a lid is provided to close the opening, and the lid pivotally supports the upper end of the sorting net and the grain-frying spiral. It has a bearing part and is screwed onto the edge of the opening from above,
A device is disclosed in which a scraping blade is fixed to the outer periphery of the m end of the sorting net for scraping out small grains that have been removed from the sorting net.

``Problem to be solved by the invention'' However, with such a conventional five-grain sorter,
Since a scraping blade that widens the diameter is provided at the base end of the sorting net, it is not possible to pull the screening net upward together with the scraping blade, but instead, open the side wall of the shell and remove the scraping blade once. Therefore, there are problems in that the workability of attaching and detaching the sorting net is poor, and additional configurations are required, resulting in high costs.

In addition, since the lid that closes the opening at the L end of the shell is exposed, the bearing is not only exposed and looks unsightly, but also contaminated with dust, which impairs durability.

In addition, since the four screws are screwed onto the edge of the opening of the shell from above, it is difficult to reach or see the screws located at a high position, making it difficult to work when attaching and removing the lid. There was.

It is tightly inserted and fitted into the end ring member 43 of No. 0. Immediately below the fitting portion of the grain guiding cylinder 50, a partition disk 52 having a circular outer circumference is fixedly projecting horizontally, and a partition disk 52 is provided on the upper surface of the partition disk 52 to engage the engagement notch 44. A plurality of scraping blades 53 forming the first member are radially arranged and erected.

Further, a plurality of grain guiding ports 54 are bored in the lower part of the grain guiding cylinder 50, and an A4 blade 55 is wound around the outer periphery to push the grains downward during rotation.

The grain guide cylinder 50 is rotatably supported on a base plate 19 that separates the base 11 and the shell 12 via a packing 20.

A drive motor 21 is attached to the lower surface of the base plate 19, and the first shaft 2 of the counter-rotating shaft 22 of the drive motor 21
2a is attached to the lower end plate 34 of the grain frying spiral body 30, and the second vehicle 22b
is connected to the bottom surface of the grain guide cylinder 50.

On the other hand, on the outside of the grain guiding cylinder 50, as shown in FIG. 1, a grain receiving cylinder 60 for receiving unsorted grains from the supply hopper 14 is disposed surrounding the grain receiving cylinder 60.

This grain receiving cylinder 60 has an edge member 61 provided horizontally outward at the upper end opening, and is in sliding contact with the lower surface of the partition disk 52 of the grain guiding cylinder 50 via a packing. Grain receiving cylinder 60
A communication port 62 with the supply port 14 is opened in the opening.

An upper partition plate 24 is provided near the upper end of the inside of the shell 12 to receive the fried and shelled good grains, and an upright wall portion 24a is formed surrounding the sorting net 40, and a deep good grain guide Y424b is provided. Or is provided. A scraping blade 4 scrapes out the grains in the good grain guide groove 24b into the storage tank 13.
5 are arranged on the sorting net 40.

Next, the effect will be explained.

Put unsorted grains into the supply hopper 14 and perform vertical grain sorting fi
When IO is started, the grain lifting spiral 30 and the grain guiding cylinder 5
The unsorted grains are sent from the supply hopper 14 into the grain receiving cylinder 60 and are pushed down by the guiding blades 55 of the grain guiding cylinder 50. The grains are then introduced into the interior through the grain guide port 54. and,
The grains are raked up by the spiral blades 32 of the grain lifting spiral body 30,
The grains are scattered toward the inner surface of the sorting net 40, and the small grains pass through the small holes 41 of the sorting net 40 and are sorted. One good grain is sent upward and falls into the good grain guide groove 24b, scraped out by the scraping blade 45, and sent to the storage tank 13.

The small grains fall downward outside the sorting net 40 and onto the partition disk 52 of the grain guiding cylinder 50. Partition disk 5
2 is provided with scraping blades 53, and the small grains are bounced by these scraping blades 53 and try to come out, and are fed into the rear opening of the small grain discharge pipe 15 and released outside. be discharged.

91, and since it rotates in sliding contact with the edge member 61 of the grain receiving cylinder 60 via the bag/null ring, the rotation is stable, and the bottom part of the sorting net 40 is a guide roller, etc. for keeping the rotation. does not require.

In addition, since both the grain lifting spiral body 30 and the grain guiding cylinder 50 connected to the sorting net 40 are driven at their lower ends, the body is expensive and obstructs the replacement of the sorting net 40. Does not require a long rotating shaft for driving.

When maintaining or replacing the sorting net 40, the shell 12
By loosening the screws 18b fastened to the screws 18a on the sides of the canopy and removing the mounting bracket 16c, the canopy 18 can be removed, as shown in FIG.
is removed from the upper end of the shell 12.

When the canopy 18 is removed, the upper end of the drive arm 42 etc. of the sorting net 40 is exposed, so hold the upper end and remove the sorting net 40.
is pulled out from the opening 12a at the upper end of the shell 12.

When extracting, from the engagement notch 44 of the end ring member 43 at the lower end of the first sorting net 40 to the scraping blade 53 at the upper end of the grain guiding cylinder 50.
Once removed, the partition disk 52 and scraping blade 53 remain on the side of the grain guiding cylinder 50, and the sorting net 40 can be easily pulled out.

When installing, insert the sorting net 40 through the opening at the upper end of the shell 12 in the reverse order, attach the top fi 1B, and screw the screw 18b.
is fastened and screwed onto the threaded portion 18a.

"Effect of IJI" According to the vertical grain sorter according to the present invention, the canopy can be removed and the sorting net can be immediately removed from the upper end of the shell. Body replacement work is extremely easy and work efficiency is improved. Since no extra configuration is required, it is possible to reduce costs.

The canopy is provided with a cover, and the screws that hold the canopy are also easily removed, which protects the bearings and improves the aesthetics of the product. ``By being able to easily remove the canopy, it is possible to improve the workability of attaching and detaching the sorting net.
