[Detailed Description of the Invention] The present invention is a device in which a paddy supply amount regulating valve provided in a removal section of a huller is opened and closed by a drive motor integrally connected to a regulating screw.

Generally, when installing the above drive motor,
A roll gap adjustment device is protruded from one side of the removing section, and since it cannot be installed there, it must be installed on the other side of the grain sorting section. However, since the space is too narrow to install it between the wind sorting unit body and the grain sorting unit body, installation is troublesome and assembly is difficult. Also, if you try to enlarge the above space,
The entire aircraft becomes larger.

Therefore, in view of the above-mentioned defects, and with the aim of improving this, the present invention has a structure in which the wind sorting section body and the grain sorting section body are divided, and the adjusting screw rod and the motor are separated, and the adjusting screw rod is detached from the main body. The motor is installed inside the grain sorting machine, and the two are connected by a removable coupling.

To explain one embodiment of the structure of the present invention shown in the drawings, 1 is the underframe of a rice huller, on the front part of which is placed the wind selection unit body 3 equipped with the removal unit 2; A grain sorting unit body 5 with a swing sorting body 4 mounted on the upper side is disposed on the side, and the wind sorting unit body 3 and the grain sorting unit body 5 are connected so as to be able to be divided and combined. A connecting bolt 7 connecting the above two 3 and 5
are fixing bolts that fix both 3 and 5 to the frame 1. Reference numeral 8 indicates a mixed rice elevator installed adjacent to the side of the wind sorting unit body 3, and reference numeral 9 indicates a gutter for taking out brown rice. 1

is a paddy supply amount control valve rotatably supported opposite to the paddy transport roll, and its tip and paddy transport roll 1
The distance of 5 is brought into contact and separated by the rotation. In other words, the opening A can be adjusted. An arm 17a is attached to an end of a rotating shaft 17 provided on the paddy supply amount regulating valve 16 that projects from the hopper receiving frame 13. Reference numeral 18 is an adjustment screw rod, which is attached to the bracket 13 which protrudes laterally from the rear of the hopper receiving frame 13.
The front end of the arm 17a contacts the tip of the arm 17a, the rear part projects toward the grain sorting unit body 5, and a driven coupling 18a, which will be described later, is fixed to the rear end. . The arm 17a
is brought into contact with the adjusting screw rod 18 by the weight of the paddy supply amount adjusting valve 16.

On the other hand, 19 is a drive motor, the motor shaft 20 of which is removably connected to the adjustment screw 18 by a pair of couplings 20a, 18a, and the drive motor 19 main body is installed in the grain sorting unit body 5. has been done. A pin 20b is protruded from the drive coupling 20a, and is inserted into a recess 18b provided in the driven coupling 18a, thereby adjusting the power of the drive motor 19.
The coupling part is configured to be able to be freely inserted and removed when the wind sorting unit body 3 and the grain sorting unit body 5 are separated and combined.

21a and 21b are sensors installed at the top and bottom of the mixed rice hopper 10, among which the upper sensor 21
The switch a is turned ON when the mixed rice increases above this level, and the lower sensor 21b is turned ON when the mixed rice decreases below this level.Both sensors 21a and 21b are connected to the drive motor 19 via the control box 22. An electric circuit is formed in the upper sensor 21a, and when the upper sensor 21a is turned on, that is, the amount of mixed rice increases, the drive motor 19 rotates in the direction to close the paddy supply amount control valve 16, and when the lower sensor 21b is turned on, that is, the amount of mixed rice increases, the paddy supply amount control valve 16 is closed. 1
6 rotates in the opening direction so that the amount of mixed rice in the mixed rice hopper 10 is always kept constant.
Reference numeral 23 denotes a partition plate, which is supported so as to be movable in the front-rear direction within the grain flow lower part 24 of the oscillating sorter 4, and is located on the upper side of the partition plate 23 (distribution gutter 11 side).
The brown rice flows down on the lower side, and the mixed rice flows down on the lower side, and the partition plate 23 is moved by looking at the sorting situation. The part is the adjustment screw 27
The nut 2 provided on the partition plate 23
3a, and the rotation of the motor 25 causes the partition plate 23 to move back and forth.
Reference numeral 26 denotes a guide rail with a U-shaped cross section provided on the inner wall of the oscillating sorter 4. A sliding plate 23b with a U-shaped cross section provided on the partition plate 23 is supported by covering the guide rail 26. Protruding bolt 2
3c is passed through an elongated hole 4a provided in the side wall of the swing sorting body 4, and is fixed from the front with a nut 23d, thereby preventing lateral rattling. In this way, one end of the adjustment screw 27 of the partition plate 23 is supported by the motor 25, but the other end is not supported by the side wall of the swinging sorter 4, but is supported only by the partition plate 23 itself, thereby making it possible to adjust the assembly. Even if a slight error occurs in the parallelism between the screw 27 and the guide rail 26, the adjustment screw is easily elastically deformed by the partition plate 23 itself so that the two become parallel.
Since the error is absorbed, the partition plate 27 can be slid smoothly.

The present invention is constructed as described above, and when assembling the wind selection section body 3 and the sorting section body 5 on the frame 1, the wind selection section body 3 is installed on the front part of the frame 1, and the fixing bolts are attached. 7, and the grain sorting section machine 5 is attached to the rear of the frame 1.
If the pin 20b of the drive coupling 20a is aligned with the recess 18b of the driven coupling 18a and pushed forward, the two bodies 3 and 5 will easily come into close contact with each other, and then the two bodies 3 and 5 will be connected with the connecting bolt 6 and further fixed. The grain sorting unit body 5 may be fixed to the frame 1 with bolts 7. Regarding the operation of the paddy supply amount adjustment valve 16, the drive motor 19 is supported by the grain sorting unit body 5, the adjustment screw 18 is not bent or deformed, and both 19 and 18 are connected by a coupling. It operates smoothly even if there is some misalignment. Next, the hulling work will be explained. The paddy supplied to the paddy hopper 12 falls between the paddy feed roll 15 and the paddy supply amount control valve 16, that is, through the opening A, is released by the rubber rolls 14, 14, and is wind-selected in the wind-selecting unit body 3. The mixed rice is then supplied to a mixed rice hopper 10 from a mixed rice elevator 8. When a certain amount of mixed rice is stored in the mixed rice hopper 10, the valve of the hopper 10 is opened and the mixed rice is supplied to the distribution gutter 11, and the mixed rice is sorted and separated into brown rice, mixed rice, and paddy by the oscillating sorter 4. The separated mixed rice is returned to the mixed rice hopper 10 via the elevator 8 again.

In the above series of hulling operations, the amount of mixed rice flowing into the mixed rice hopper 10 varies depending on the quality of the paddy, the degree of reduction, etc., and if the amount of inflow increases and exceeds the upper sensor 21a, control The drive motor 19 is operated according to the instruction from the box 22, and the paddy supply control valve 16 is moved in the closing direction, and the opening A is narrowed.Therefore, the amount of paddy supplied to the rubber roll 14 is reduced, so that the level of mixed rice in the mixed rice hopper 10 is reduced. It's coming down too. Conversely, if the mixed rice level falls below the lower sensor 21b, the drive motor 19 rotates in the opposite direction to open the opening A and the mixed rice level rises. In this way, the level in the mixed rice hopper 10 is stabilized, and the amount of mixed rice supplied to the oscillating sorter 4 is kept constant.

As described above, the present invention is a rice hulling machine in which the wind sorting section machine body on which the shedding section is mounted and the grain sorting section machine body on which the swinging sorting body is installed can be freely divided and combined,
