Description

Detailed Description of the Invention "Industrial Field of Application" The present invention comprises a rotary sorting tube that is erected within 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. 6, for example.

That is, FIG. 6 shows a rotary sorting tube l of a conventional granule sorter. is discharge port 3.3
... has been established.

Supports 4.4 are interposed between the discharge ports 3, 3... corresponding to the number of discharge ports 3.3..., and lightening holes 5, 5... are provided in the top plate. It is perforated.

[Problems to be Solved by the Invention] However, in such a conventional technique, if the particles try to exit from the discharge port 3 while the rotating sorting cylinder l and the spiral body inside thereof are reversed.

There is a problem in that the particles collide with the column 4 one after another at a large relative speed, and the particles are likely to be pushed back inward by the reaction, resulting in poor discharge efficiency.Also, since it has a top plate, it is difficult to manually enter the rotating sorting tube l. Therefore, there was a problem in that it was impossible to clean the dust such as rice sugar that had adhered to the inside of the sorting tube 1.

The present invention has been made in view of these conventional problems, and includes a rotary sorting tube with a discharge port that has good discharge efficiency and is easy to clean, that is, it straddles a thin wooden arm-shaped pivot bracket. The object of the present invention is to provide a granule sorting machine that solves the above problems.

The gist of the present invention to achieve the above object is to provide a rotary sorting cylinder upright in an outer cylinder, and a lifting granule in the rotating sorting cylinder in the opposite direction. In a granule sorting machine equipped with a spiral body, the top of the rotary sorting cylinder is fully opened, and a thin arm-shaped pivot bracket is installed at the top, and both legs of the pivot bracket are opened. A particle sorting machine is characterized in that the particle sorting machine is fixed to the edge of the top of a rotating sorting cylinder.

"Function" However, since the granule discharge opening is formed in most of the top of the rotary sorting tube, the granules lifted by the spiral body are not returned to the inside and can be efficiently discharged from the discharge opening. is discharged,
In addition, since the user can easily insert his/her hand through the opening, rice sugar etc. adhering to the inside can be cleaned very easily.

"Example" Hereinafter, the present invention will be described in detail based on the drawings. Note that similar parts in each embodiment are designated by the same reference numerals, and redundant explanation will be omitted.

1 to 5 show embodiments of the invention.

As can be seen in FIG. 4, the granule sorting machine 10 includes a rotary sorting tube 40 that is provided within the tube 20 and rotates a spiral body 30 therein.

The outer cylinder 20 has a supply hopper 21 for granules at the lower part, a collection chamber 22 for sorted granules at the upper end, and a discharge hopper 24 projecting laterally from the collection chamber 22. A shutter 25 for controlling discharge is provided. Also, on the opposite side of the supply hopper 21 is a discharge port 2 for sorted grains.
6 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 a12.

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

The rotary sorting cylinder 40 is connected to the reducer a12 so as to rotate in the opposite direction to the spiral body 30, and the receiving port 41 at the lower end is connected to the outer cylinder 2.
The middle portion of the 0-rotation sorting tube 40, which communicates with the 0-rotation feed hopper 21, forms a sieve portion 42 having a large number of through holes.

As can be seen in FIGS. 1 to 3 and FIGS. 5(A) and 5(B), the top of the rotary sorting tube 40 is fully opened, and the end edge 4
A pivot bracket 44 is fixedly attached to 3. The pivot bracket 44 has a thin arm shape, and is fixedly installed on the top edge 43 of the rotary sorting cylinder 40.
The pivot bushing 4 crosses the central axis of the rotary sorting cylinder 40.
A pivot bracket 44 is fixed at the top of the 0-rotation sorting cylinder 40 to which a pivot bush 44b is fixedly mounted and a pivot bush 44b is pivoted to the pivot shaft 13.
All openings other than the space occupied by the discharge port 45 form the discharge port 45.

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 sorting filO is operated by rotating the rotary sorting cylinder 40 within the outer cylinder 20, and further rotating the spiral body 30 within the rotary sorting cylinder 4o in the direction opposite to that of the rotary sorting cylinder 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 3o and the rotary sorter 040 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 sorter 040, 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.
The liquid reaches the discharge port 45 at the upper 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. When the shutter 25 is opened, it is collected three times.

After the sorting and weighing work is completed, the rotary sorting tube 40 is pulled out, and the pivot bracket 44 is attached as shown in FIGS. 5(A) and 5(B).
Insert your hand into the rotary sorting tube 40 from the side and use a brush, cloth, etc. to clean off the attached rice sugar, etc.

"Effects of the Invention" According to the granule sorter according to the present invention, a large 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. Particles are efficiently discharged without being pushed back, resulting in a highly efficient particle sorter, and the discharge port is wide open, making it extremely easy to insert your hand into the rotating sorting tube through this opening. This makes cleaning extremely easy.
