Description

Detailed Description of the Invention "Industrial Application Field" The present invention provides a grain-flipping spiral body in which a spiral blade is wound around the outer periphery of a cylindrical body in an outer shell body, and a grain-flipping spiral body that is concentrically inserted into a large number of grains. The present invention relates to a vertical grain sorting machine which houses a sorting net body provided with small holes and feeds unsorted grains to the base of a grain lifting spiral body and sorts the grains while frying the grains.

``Prior Art'' In a conventional vertical grain sorter l, a feed hopper 2 for supplying unsorted grains is connected to a grain receiver adjacent to and surrounding the base of a grain lifting helix 3, as shown in FIG. It opened directly into the tube 4.

A residual grain discharge pipe 5 for discharging the grains remaining at the bottom of the grain receiving cylinder 4 at the end of one sorting process, and a discharge gate 6 at the bottom of the grain receiving cylinder 4 were provided.

"Problems to be Solved by the Invention" However, in such a conventional vertical grain sorter 1, the unsorted grains fed from the supply hopper 2 are directly supplied to the grain lifting spiral body 3, so that the unsorted grains are not received properly. Unsorted grains to be fed into the grain barrel 4 and grains to be scraped up by the spiral blades 5 of the grain lifting spiral body 3 compete fiercely at the opening 2a of the supply hopper 2, Smooth feeding was obstructed.

When the amount of grains supplied to the supply hopper 2 becomes less than a certain amount, the grains trying to enter the grain receiving tube 4 from the opening 2a and the grains thrown out by the grain lifting spiral body 3 are balanced. When the grain feeding is effectively stopped and the operation is stopped, the grains remaining near the opening 2a enter the grain receiving tube 4, forming a large amount of residual grains and passing through the discharge gate 6. It was difficult to remove all the remaining grains even when the grains were opened.

The present invention was made by focusing on such conventional problems, and by surrounding the base of the grain frying spiral and interposing an appropriate unsorted grain guiding means, grains can be smoothly grained. Not only is it possible to feed grains from the feed hopper, but even if the amount fed from the feed hopper is small, it can all be fed into the receiving tube. The purpose of this invention is to provide a vertical grain sorter that can remove all grains without leaving any residue.

"Means for Solving the Problems" The gist of the present invention for achieving the above object is to provide an external device equipped with a supply hopper for supplying unsorted grains and a storage tank for storing refined grains outside the body. A grain lifting spiral body, in which a spiral blade is wound around the outer circumference of a cylinder, and a sorting net body, in which the grain lifting spiral body is inserted concentrically, are housed inside the shell so as to be rotatable relative to each other, and grains are sorted. ,! ! ! In the grain sorting machine, the grain sorting machine is provided surrounding the base of the grain lifting helix, and has a horizontal peripheral edge portion opening outwardly at the upper end opening followed by a cylindrical peripheral edge elevation, and has a cylindrical peripheral edge elevation surface that is continuous with an outwardly opened horizontal peripheral edge portion, and has a cylindrical peripheral edge elevation surface that is continuous with an outwardly opened horizontal peripheral edge portion, and has a cylindrical peripheral edge elevation. A grain receiving tube is provided for receiving grains and supplying the grains to the grain lifting spiral, and the grain receiving tube is interposed between the grain receiving tube and the base of the grain lifting spiral,
A cylindrical grain guiding cylinder is provided which is connected to the lower end of the sorting net and rotates, and whose lower end stands upright in sliding contact with the horizontal bottom of the grain receiving cylinder. A vertical grain characterized by having a plurality of grain guiding ports bored in the lower end thereof, and having grain guiding blades whose starting end is near the upper edge line of each grain guiding port and which points downward during rotation. It exists in the sorting machine.

"Action" Feed unsorted grain into the feed hopper and start the vertical grain sorter.

The unsorted grains fed from the supply hopper are placed in the grain receiving cylinder provided at the base of the grain lifting spiral body, and are guided by a grain guiding cylinder of approximately the same diameter that rotates in the same direction as the sorting net. The grains are pushed downward by the blades and sent from a plurality of grain guiding ports provided on the lower circumferential surface of the grain guiding cylinder to the starting end of the grain lifting spiral rotating in the opposite direction to the sorting net. be provided.

The grains raked up by the grain lifting spiral are thrown outward and are subjected to a sorting action by the sorting net, and small grains are eliminated by passing through the sorting net. The grain rises as it is and is stored in a storage tank.

The unsorted grains fed from the supply hopper are pushed down by the grain guiding blades and introduced from the grain guiding port, so that the grains scraped up by the spiral blades of the grain lifting helix and the grains from the feeding hopper are The supplied grains do not interfere with each other and are smoothly fed, increasing the amount of grains fed.

Even if the sorting work is about to end and the amount of grain supplied from the supply hopper decreases, the opening in the grain receiving tube of the supply hopper is opened higher than the grain guide port.
Since it does not open directly into the grain lifting spiral, it is not bounced back by the grain lifting spiral and is fed into the grain receiving cylinder until the end.

After the grain supply is stopped, the grains falling from above are discharged outward at the bottom of the grain guiding cylinder, but due to the slope of the tapered part of the grain receiving cylinder. It is not widely diffused, is eliminated externally, and does not remain in the body.

Vertical grain sorting a by supplying unsorted grains to the supply hopper 19
When the lO is started, the grain guiding cylinder 30 rotates slowly together with the sorting net 16, and the grain guiding blades 35 move the grains fed from the opening 19a of the grain receiving cylinder 20 of the supply hopper 19 downward. push away The grains are transported along the tapered portion 21 of the grain receiving tube 20 from the grain guiding port 34 to the grain guiding tube 30.
pushed inside.

Inside the grain guiding cylinder 30, the grain lifting spiral 14 rotates at high speed in the opposite direction to scrape up grains, and the sorting net 16
The small holes 15 are used for sorting. In other words, the small grains that have passed through the small holes 15 are separated from the outer periphery of the sorting net 16 and the outer shell 1.
The grains fall through the space on the inner wall of the grain guiding cylinder 30 and tend to be deposited on the surface of the partition disk 32 provided on the outer periphery of the grain guiding cylinder 30. However, since the partition disk 32 is rotating together with the sorting net 16, the small grains are thrown outward and are discharged from the small grain discharge pipe 11a.

On the other hand, good grains that cannot pass through the small holes 15 of the sorting net 16 are lifted upwards, although some of them repeatedly fall, and are eventually accumulated in a storage tank.

The opening 19a of the supply hopper 19 does not directly open into the spiral blade 13 of the grain lifting spiral 14, and the grain guiding port 34 is provided considerably below the opening 19a, so that the grain lifting spiral There is no rebound from the grain receiving tube 14, and along with the effect of the inclination of the tapered portion 21 of the grain receiving tube 20, smooth grain feeding is achieved, and the amount of grain fed is increased.

Even if the sorting work is about to be completed and the amount of grain supplied from the supply hopper 19 decreases, the opening 19a in the grain receiving tube 20 of the supply hopper 19 is located higher than the grain guide port 34. Since it is open and does not directly open into the grain lifting spiral 14, the grains are not bounced back by the grain lifting spiral 14 and are finally fed into the grain receiving cylinder 20.

After the grain supply is stopped, the grains falling from above are discharged outward from the grain guiding port 34 by centrifugal force at the bottom of the grain guiding cylinder 30. If the grain is small amount.

The effect of the grain guiding blades 35 is no longer, and the grain guiding cylinder 3
The particles are not pushed back toward zero, and due to the inclination of the tapered part 21 of the particle receiving tube 20, they are not widely dispersed.
The residual grains pass through the opened residual grain discharge gate 42 and are discharged to the outside from the residual grain discharge pipe 41, and do not remain in the body.
