を容易に図ることができるものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a sorting section for separating and removing swarf kernels from grains inside a vertical rotation sorting cylinder during planetary motion of the cylinder, and the sorting section. The present invention relates to a grain sorting device provided with a grain taking-out mechanism for taking out good-quality grains and refuse grains sorted out in the apparatus. BACKGROUND ART Conventionally, as shown in JP-A-61-64374, a receiving hopper for charging brown rice, a vertical sorting cylinder for separating waste rice, and a uniform brown rice removed from the sorting cylinder are used for uniform rice raising. There is a technology to set up a brown rice tank for receiving from a grain conveyor, and to separate the brown rice input into brown rice and scrap rice. "Problems to be Solved by the Invention" Since the prior art sets up a brown rice milling conveyor on the outside of a cylindrical machine frame in which a sorting cylinder is installed, simplification of the mounting structure of the conveyor and reduction in mounting strength. In addition, it is difficult to secure the waste rice, and the waste rice is taken out to a lower position, so that the collecting work position of the waste rice is lowered. Also, by providing the conveyor outside the machine frame in which the sorting cylinder is installed, a drive motor is provided at the bottom of the machine frame to drive the sorting cylinder, and the conveyor is also driven by the motor,
There is a problem that the conveyor drive mechanism is exposed outside the machine frame. “Means for Solving the Problems” However, the present invention receives a receiving hopper for charging brown rice, a vertical sorting cylinder for separating waste rice, and a uniform brown rice extracted from the sorting cylinder from a uniform brown rice fry conveyor. In a grain sorting device that provides a brown rice tank and separates the introduced brown rice into brown rice and scrap rice, a sorting unit for installing the sorting cylinder therein, and a brown rice conveyor room for installing therein a browned rice frying conveyor, A waste rice conveyor room with a waste rice frying conveyor inside,
The machine is formed by using a vertical partition plate inside a vertically long rectangular box-shaped machine frame, and a sorting rice conveyer room and a waste rice conveyer room are arranged adjacent to one side of a sorting unit having a quadrangular shape in a plan view. The feed start end on the lower end of each conveyor is connected to a drive motor on the bottom of the frame, and the lower end of the sorting cylinder is connected to the lower drive side of each conveyor via a speed change mechanism. [Operation] Therefore, since the inside of the machine frame is partitioned by a partition plate to form each of the conveyor chambers, the mounting structure of each of the conveyors can be simplified and the mounting strength can be easily ensured. And the outer shape of each conveyor chamber can be simply formed, and each conveyor can be driven at a constant speed by the drive motor, and the sorting cylinder can be driven at a speed suitable for sorting, thereby lowering the unloading efficiency of each conveyor.

The side wall surface (22) that separates from the upper brown rice tank (7)
In a), a brown rice storage tank inlet (97) for charging the brown rice, which has been fried by the conveyor (6), into the tank (7) is opened, and the bottom flow lower surface (7a) of the tank (7) is opened. At the starting end of the flow, a regular rice overflow port (98) is opened in the side wall surface (22a) between the hopper (3) and the regular rice tank (7), and the overflow port (98) between the inlet (97) and the overflow port (98) is opened. A jam plate (99) is interposed on the lower surface (7a) of the tank, and when the tank (7) is full and the conditioned rice overflows from the overflow port (98), an overflow passage (10) is formed.
0) through the hopper (3) below. Further, as shown in FIG. 10, a sealing member (see FIG. 10) for sealing a gap between the bottom surfaces of the upper and lower disks (17) and (18) is provided on the inner bent edges of the scrap rice and the unpolished rice gutter (69) (70). 101) is fixed so as to prevent the scrap rice and the brown rice in each gutter (69) (70) from spilling downward inside the gutter. The lower end of the sorting tube (4) is a lower receiving member (19).
Of the outer peripheral rim portion (19b), extending downward by a dimension (t) below the lower surface of the sorting tube (4).
It is configured to prevent the conditioned brown rice that is skipped by the arm portion (19c) from scattering to the inside of the waste rice gutter (69) in the nearby position. This embodiment is configured as described above, and the brown rice fed into the brown rice receiving hopper (3) from one of the inlets (2a) and (2b) is fed into the sorting cylinder (4). After the waste rice is separated and removed by the sorting cylinder (4), the waste rice is fried to a brown rice storage tank (7) via a fry conveyor (6), and is appropriately taken out of the machine. Thus, during the revolution and rotation of the sorting cylinder (4), the leakage of the scrap rice from the mesh (90) is promoted by the action of the centrifugal force during the revolution, and the revolving direction (a). By the reverse rotation stirring action, the brown rice is agitated in a uniform distribution state in the cylinder (4), further promoting the separation of the scrap rice, and allowing the brown rice to flow down along the inner peripheral surface of the cylinder (4) while rotating the brown rice well. The processing capacity is improved. Further, even when the revolving speed of the sorting cylinder (4) is changed to high or low speed to adjust the sorting accuracy, the speed ratio between the revolving speed and the rotation speed is always constant. There is no inconvenience that brown rice sticks to the outside of the inner peripheral surface or the downward flow is promoted more than a predetermined amount, so that the work can be performed in a state where the balance between the sorting accuracy and the processing capacity is always kept in a good condition. Further, the scraped rice-frying screw conveyor (53) is directly linked to the motor (32) separately from the drive transmission system of the selection unit (91) via a disk friction wheel type continuously variable transmission mechanism (57). Since they are connected, they can be installed side by side and close to the motor (32), and can be compactly assembled. In addition, since the shift width is small, generation of broken rice by the screw conveyor (53) is prevented. Further, the rotational driving force from the motor (32) is sequentially applied to the screw conveyor (53). Fried conveyor (6). The structure is such that the conveyor (6) and (53) are transmitted to the sorting unit (91) to the low-speed side and the conveyors (6) and (53) are arranged side by side adjacent to the left and right of the sorting unit (91). And further improvement in functionality. On the other hand, the inlets (2a) and (2b) are provided on the right side and the rear side of the fuselage, and each of the opposing surfaces has a closed structure so that the other port (2a) or (2b) can be used when either one is used. Even if it is not closed with a cover or the like, there is no scattering of brown rice and it can be used conveniently. Also, as shown in FIGS. 2 to 4, by removing the front and rear side covers (102a) and (102b) substantially at the front and rear sides of the fuselage, the sorting unit (91) and the fry conveyor (6) are provided on the front side. ), And on the rear side, it can be opened across both the sorting section (91) and the screw conveyor (53), and both can be inspected simultaneously.
