Description

[Detailed description of the invention] The present invention relates to a rotary grain sorter.

In other words, the rotary sorting tube that separates and sorts brown rice from a mixture of paddy and brown rice has a double structure, allowing both sorting tubes to sort with high precision and efficiency, and grain transfer between the two sorting tubes. To provide a device that can be smoothly transferred to a target 11 by simply dropping it downward without being raised by a thrower or the like, and can be simplified in structure and made compact, and can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a side view of the rice hulling and sorting device. There is a No. 2 conveyor (4) in the selection box (E).
A mixed rice conveyor (5), a paddy conveyor (6), a brown rice conveyor (7), etc. are installed inside the gutter, and a wind selection box (

A Kaison-type grain sorter (C) is installed above the other half of the wind sorting box (E). A large-diameter sorting tube (A) is charged, and the sorting tube rA) is formed with a large number of recesses (11) on the inner circumferential surface and open at both ends, and the size of the sorting tube rA) is large enough to fit the brown rice. Both ends 4 [11

Inside the large-diameter rotary sorting tube (A) and above the receiving gutter (B), there is a double small-diameter rotary sorting tube (a) formed with many concave portions (]) like the sorting tube (A). A case (■-shaped brown rice receiving gutter fb supported from the I91 side) is fixedly installed inside the sorting tube (a), which has an open shape at both ends. A spiral conveyor d that rotates around the rotating shaft is installed at the lower center of b), and the support arm device at the other end (c) of the small-diameter rotary sorting tube la) that is on the hulling part jF) is connected to the rotating shaft (3). ), and one end side of the sorting tube (a) (

A supply gutter (3) attached to the case II mark is interposed in communication between the bottom inner side of one end side (C port) of the small diameter rotary sorting tube (1) and the other end side (C) A gutter (32) is installed so that the lower part of the gutter (32) communicates with the upper part of the paddy conveyor (6).

In addition, at the upper part of the opposite side of both receiving troughs (B) I'b), adjustment plates OIh extending obliquely so as to approach the inner circumferential surface of the sorting @ (A) /al are installed in series. The adjustment plate eel d is installed so that the inclination can be changed by moving about the axis C (41tsi), and the base of the adjustment body +351os is attached to the tip of the shaft (2)- extending outward from the case mark. It is constructed by installing it so that it can be engaged with the knock-like case (the chrysanthemum seat (to) on the 1 mark side) which is fixedly installed and fitted with a spring (T) at the tip of the adjustment body (G5105). .

During operation, when paddy is fed to the hora/: -+151, the mixed rice removed by the huller (F) is sorted in the winnowing box (E) and transferred to the mixed rice conveyor (5). As the person fell, the mixed rice thrower IF81 opened the supply tank (
The mixed rice that is jumped up into the tank (2) and fed into one end (a) of the small-diameter rotating sorting tube (a) from the bottom opening of the tank (2) is fed into the nuclear sorting tube that rotates in the direction of the arrow (e). In contact with the inner peripheral surface of (a), the brown rice fits into the recess (1) and is lifted upward, but the paddy cannot fit into the recess (1) and slides down. Recess (

The rice will then be returned to the Yotte Hopper D51 and the rice will be hulled again.

On the other hand, brown rice, etc., which is sent to one end side by the spiral conveyor (as indicated by the arrow (G) in BL) is sent to the supply gutter (3).
If a person falls into the room, a large-diameter rotating sorting tube will be released from the bottom opening.
The brown rice, etc. is fed inward from one end of A) and rotated as shown by the arrow (F) by the sorting cylinder (A), where it is circulated and sorted in the same manner as described above. The mixed rice that has fallen onto the spiral conveyor in B) and has been sorted is transferred inside the sorting tube (A) as shown by the arrow (man) and passes through the falling plate ω from the other end (B). The rice falls onto the mixed rice conveyor (5) and the mixed rice thrower (181) transfers it to the supply tank (2).
), the brown rice is sent by the spiral conveyor (241) as shown by the arrow (nu) from the gutter ■ to the brown rice conveyor (7).

Note that by operating the adjustment body 0909, the receiving plate 0
By changing the slope of 3 n%, the acceptance state of brown rice can be adjusted.

In this way, the present invention provides a large-diameter rotary sorting joint (A
) is equipped with a small-diameter rotary sorting tube (a) of the same structure in a double layer, and inside both sorting tubes (A) (a), a receiving trough (B) fb) for receiving brown rice is fixed. The small-diameter rotary sorting cylinder (a) is connected to one end (a) of the small-diameter rotary sorting cylinder (a), and the receiving gutter inside the small-diameter rotary sorting tube (a) is connected so that mixed rice can be supplied from the outer supply tank (2) to one end (a) of the small-diameter rotary sorting cylinder (a). fb) and large diameter rotary sorting m IA
A supply gutter (3) is interposed in communication between one end side (b) and the inside of ), so the rotary sorting tube for separating and sorting brown rice from the mixed rice of paddy and brown rice has a double structure. Both sorting tubes (8a
) Grain can be sorted more accurately and efficiently than VC, and the grain transfer between the two sorting tubes (A) and 'a) can be carried out with a thrower.
etc., it is possible to transfer grains reliably and smoothly simply by dropping them downward without raising -H, and also to make the whole structure simple and compact with a double structure and a downward grain transport structure. It has the feature that it can be carried out suitably.
