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, feeds unsorted grains to the base of a grain-flinging spiral body, and sorts the grains while frying them.

``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.

Further, the hem portion of the spiral net body 6 was supported by a plurality of guide roller roughs so as not to whirl around during rotation.

"Problems to be Solved by the Invention" However, in such a conventional vertical grain sorter l, the unsorted grains fed from the supply hopper 2 are directly supplied to the grain lifting spiral 3, 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.

Further, the guide roller 7 provided to prevent the hem of the sorting net 6 from swinging around becomes an obstacle when replacing the first sorting net 6, making the replacement work time-consuming.

The present invention has been made by focusing on such conventional problems, and by surrounding the base of the JIAB spiral and interposing an appropriate unsorted grain guiding means, it is possible to smoothly form grains. It is an object of the present invention to provide a vertical grain sorting machine which not only enables feeding but also does not require guide rollers and therefore does not take much time to replace a sorting net.

"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. Inside the shell, a grain lifting spiral body in which a spiral blade is wound around the outer periphery of a cylinder, and a sorting net body in which the grain lifting spiral body is inserted concentrically are housed in relative rotating shoulders to sort grains. In the vertical grain sorter, the force field is provided surrounding the base of the grain lifting helix, and the upper end opening has an outwardly opened horizontal peripheral edge followed by a cylindrical peripheral edge elevation, and the feed hopper a grain receiving tube is provided which receives unsorted grains from the grain receiving tube and supplies it to the grain frying spiral, and is interposed between the grain receiving tube and the base of the m-grain spiral;
It rotates while being connected to the lower end of the sorting net, the lower end is erected in sliding contact with the horizontal bottom of the grain receiving cylinder, and the part near the upper end is in sliding contact with the peripheral edge of the grain receiving cylinder, and the peripheral edge A cylindrical grain guiding cylinder is provided with an annular partition disk horizontally fixed to the entire inner circumference of the vertical surface, and a plurality of grain guiding ports are provided at the lower end of the grain guiding cylinder. The vertical grain sorting machine is characterized in that a grain guiding blade is provided at a starting point near the upper edge of each grain guiding port and extending downwardly during one revolution.

"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 are passed through 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 body which rotates in the opposite direction to the sorting net. will be sent.

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.

Further, the grain guiding cylinder rotates while being supported by the horizontal bottom part of the grain receiving cylinder and the upper peripheral part, and in particular, the outer periphery of the partition disk is extended to the full inner circumference of the peripheral edge elevation of the peripheral part. Because it is expanding
The rotational position does not shift, and there is no need for a conventional guide roller that rotatably supports the base of the sorting net.

"Example" Hereinafter, one embodiment of the present invention will be described based on the drawings.

The vertical grain sorter 10 includes a grain lifting spiral body 14 formed by winding a spiral impeller 3 around the outer periphery of a cylindrical body 12 in an outer shell body 11 that is vertically installed, and a grain lifting spiral body 14 that is concentric with the grain lifting spiral body 14. A sorting net 16 having a large number of small holes 15 is housed surrounding the outside.

The grain lifting spiral body 14 and the sorting net body 16 are driven to rotate in opposite directions to each other by a motor 18 with a speed reducer provided at the lower part of a base plate 17 that partitions the inside of the outer shell body 11 into upper and lower parts.

Outside the shell body 1, there is a supply hopper 1 for supplying unsorted grains.
9 is provided, and a storage tank (not shown) for temporarily storing refined grain is provided at the head.

On the upper surface of the base plate 17, a grain receiving cylinder 20 is erected, which has a cylindrical shape and a tapered part 21 having an a-head conical shape at the bottom, and the upper opening end is a horizontally opened peripheral part. 22, and then a parallel peripheral edge elevation 22a. The supply hopper 19 has an opening 19a near the center of the grain receiving cylinder 20.
have.

On the other hand, at the bottom of the sorting net 16 is a grain guiding cylinder 3 having approximately the same diameter.
0 is provided to be removably attached to the lower end of the sorting net 16. The upper end 31 of this grain guide cylinder 30 is connected to the sorting net 16
The end shaft member 16a of the sorting net 16 has an engagement notch for driving the grain guiding cylinder 30. 16b
is engraved. A partition disk 32 is horizontally fixed to the outer periphery of one of the grain guide cylinders 30, and a plurality of locking members 33 that lock into the engagement notches 16b are arranged.

As shown in FIG. 2, the partition disk 32 has a circular outer periphery, and as shown in FIG. The outer periphery is sized to fill the entire inner periphery of the peripheral edge elevation 22a of the particle receiving cylinder 20. Further, as described above, the locking member 33 is
It engages with the engaging notch 16b of the sorting net 16, transmits the rotation of the sorting net 16 to the grain guiding cylinder 30, and removes small grains that have passed through the small holes 15 of the sorting net 16 and fallen. The grains are discharged to the outside from the small grain discharge pipe 11a.

On the other hand, a plurality of grain guiding ports 34 are bored in the lower end of the grain guiding cylinder 30, as shown in each figure. As shown in FIG. 1, these grain guide ports 34 have their upper edge lines 34a located far below the lower edge of the opening 19a in the grain receiving cylinder 20 of the supply hopper 19.

Furthermore, a plurality of grain guiding blades 35 are provided which have starting ends close to the upper edge line 34a of each grain guiding port 34 and which face downward during rotation.

Next, the effect will be explained.

When the vertical grain sorter 10 is started by supplying unsorted grains to the supply hopper 19, the grain guiding cylinder 3o slowly rotates together with the sorting net body 16, and the grain guiding blades 35 move toward the receiving end of the supply hopper 19. The grains fed from the opening 19a in the grain cylinder 2o are pushed downward. The grains flow along the tapered portion 21 of the grain receiving tube 20 from the grain guiding port 34 to the grain guiding tube 3o.

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. That is, 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 out.

The small grains are discharged to the outside from the grain discharge pipe 11a.

On the other hand, good grains that cannot pass through the small holes 15 of the sorting net 16 are carried upward by 4g even though some of them repeatedly fall.
Eventually, it will be accumulated in a storage tank.

The opening 19a of the supply hopper 19 does not open directly into the spiral blade 13 of the grain lifting spiral 14, and the grain guiding port 34 is provided considerably below the opening 19a. There is no rebound from the grain receiving tube 20, 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.

Further, the grain guiding cylinder 30 is tightly fitted into the hem of the sorting net 16, and is supported in sliding contact with the peripheral edge 22 and the horizontal bottom of the grain receiving cylinder 20, and the partition disc 32 is connected to the grain receiving cylinder. 20 peripheral elevations 2
Since 2a is fully expanded, rotational runout does not occur even without a guide roller.

"Effects of the Invention" According to the vertical grain sorting machine according to the present invention, a grain receiving tube having a tapered portion at the bottom is provided, and a grain receiving tube that rotates together with the spiral net body is provided between the grain receiving tube and the grain lifting spiral body. A grain guiding cylinder is provided, a grain guiding port for introducing grains is provided at the bottom of the grain guiding cylinder, and grain guiding blades are provided in the grain guiding port, so that grains are fed from the supply hopper. The grains that are removed and the grains that are scattered by the grain lifting spiral do not interfere with each other, and the grains are supplied smoothly, making it possible to increase the feeding amount. Since there is no need for guide rollers that rotate and support the hem, it does not take much time to replace the sorting net.
