Description

Detailed Description of the Invention "Industrial Field of Application J The present invention comprises a rotary sorting tube that is erected in an outer cylinder, and a grain lifting spiral body that is arranged in the opposite direction to the rotary sorting tube. The present invention relates to a granule sorting machine.

``Prior Art'' As a conventional technique, there is one shown in FIG. 9, for example.

That is, FIG. 9 shows a rotary sorting tube 1 of a conventional granule sorter. is discharge port 3,3
... has been opened, and a support 4 is installed between the outlet 3° and 3...
, 4 . . . corresponding to the number of discharge ports 3, 3 . . . are interposed therebetween, and relief holes 5, 5 .

``Problems to be Solved by the Invention'' However, with such conventional technology, when particles try to exit from the discharge port 3 while the rotary sorting tube l and the spiral body inside it are reversed, a large amount of There was a problem in that the granules collided with the column 4 one after another at a relative speed, and the granules were likely to be pushed back inward by the reaction, resulting in poor discharge efficiency.

The present invention has been made in view of these conventional problems, and an object of the present invention is to provide a granule sorting machine that solves the above problems by providing a single-rotation sorting tube with a discharge port with high discharge efficiency. It is said that

``Means for Solving the Problems'' The gist of the present invention for achieving the above object is that a rotating sorting cylinder is installed upright in an outer cylinder, and a granule lifting device that is placed in the rotating sorting cylinder in the opposite direction. In a granule sorting machine that is equipped with a spiral body, a thin arm-shaped pivot bracket is fixed to the top of the rotary sorting tube, and the space at the top of the rotary sorting tube other than the space occupied by the pivot bracket is fixed to the top of the rotating sorting tube. A granule sorter is characterized in that the upper surface and the side surfaces are used as granule discharge ports.

"Function" Therefore, the granule discharge port occupies most of the top of the cylinder with rotational speed ff11, and the granules lifted by the spiral body are not returned to the inside, but are efficiently ejected from the discharge port. It is something that is discharged.

"Embodiments" Various embodiments of the present invention will be described below based on one drawing. Note that similar parts in each embodiment are designated by the same reference numerals, and redundant explanation will be omitted.

1 to 4 show a first embodiment of the present invention.

As can be seen in FIG. 4, the particle sorting filO is
A rotary sorting cylinder 40 for internally rotating the spiral body 30 is provided upright therein.

The outer cylinder 20 has a granule supply hopper 21 at the bottom, a collection chamber 22 for sorted granules at the upper end, and a collection chamber 22 for the sorted granules.
It has a discharge hopper 24 projecting laterally from the discharge hopper 2, and the discharge hopper 24 is provided with a shutter 25 for discharge control. Also, on the opposite side of the supply hopper 21 is a discharge port 26 for sorted grains.
is provided.

The spiral body 30 and the rotary sorting cylinder 40 are driven to rotate in opposite directions by the motor 11 and reducer 12 at the lower part. Naturally, the spiral body 30 rotates in a direction that lifts the grains.

The lower end of the spiral body 30 is supported by the speed reducer 12 .

One end is pivotally supported by the outer cylinder 20 by a pivot 13, and has a spiral blade 31 on the outer periphery.

The rotating sorting tube 40 is decelerated so as to rotate in the opposite direction to the spiral body 30! a12, and the receiving port 41 at the lower end communicates with the supply hopper 21 of the outer cylinder 20. Rotary sorting cylinder 40
The middle part thereof forms a sieve part 42 having a large number of through holes.

As can be seen in FIGS. 1 to 3, a pivot bracket 44 is fixed to the top edge 43 of the rotary sorting tube 40. As shown in FIGS. The pivot bracket 44 has a thin arm shape and can be rotated once for selection f: 1I.
The pivot bracket 44 crosses the opening at the top of the rotary sorting tube 40, and is installed with its legs 44a, 44a fixed to the edge 43 of the top. The pivot bush 44b is fixed to the pivot 13.
The opening other than the space occupied by the pivot bracket 44 at the top of the 0-rotation sorting tube 40 which is pivoted to is a discharge port 45.
is doing.

At the edge 43 of the top of the opening at the top of the rotary sorting cylinder 40, there is a scraping blade 46, 46 that rotates within the collection chamber 22 of the outer cylinder 20.
... is installed.

Next, the action will be explained.

The granule sorter 4i110 is operated by rotating the rotary sorting tube 40 within the outer cylinder 20, and further rotating the spiral body 30 within the rotary sorting tube 40 in a direction opposite to that of the rotary sorting tube 40, in which the grains are lifted.

When grains such as grains are fed into the supply hopper 21, the grains enter the space between the spiral body 30 and the rotary sorting tube 40 through the receiving port 41, and are lifted by the spiral blades 31 of the spiral body 30. During the lifting process, small particles are passed through the sieve section 42.
The liquid passes through the through hole, exits the rotary sorting cylinder 40, and is discharged from the discharge port 26.

The particles that have passed through the sieve section 42 rise further and pass through the rotary sorting cylinder 4.
It reaches the discharge port 45 at the end of 0 and overflows into the collection chamber 22 from the wide open mouth. Since the legs 44a of the pivot bracket 44 are thin and occupy only a small space, the granules to be discharged will not collide with each other and be returned. Overflowing granules are scraped into the discharge hopper 24 by the scraping blades 46. is stored and collected when the shutter 25 is opened.

FIGS. 5 and 6 show a second embodiment, in which arm portions 47a, 47a are divided into three.

A pivot bracket 47 having a diameter 47a is provided. The pivot bracket 47 has leg portions 47b.

47b, 47b connect the top edge 43 of the rotary sorting cylinder 40 to 3
They are fixed at equally divided positions, and a pivot bush 44b is fixed at the center.

7 and 8 show a third embodiment, in which a pivot bracket 48 in the form of a single cantilever arm is provided. The pivot bracket 48 has a leg portion 48a fixed to one end of the top edge 43 of the rotary sorting tube 40, and an arm portion 48b extending to the central axis of the rotary sorting tube 40, to which a pivot bushing 44b is fixed. .

"Effects of the Invention" According to the granule sorter according to the present invention, a wide discharge port is formed at the top of the rotary sorting cylinder, and the legs of the pivot bracket are thin and occupy only a small space. The particles are efficiently discharged without being pushed back, resulting in a particle sorter with high operating efficiency.
