Description

[Detailed description of the invention]

(Industrial Application Field) The present invention relates to an angle adjustment device for a rotary grain sorting device attached to a hulling device. (Prior art) Conventionally, a huller consists of a huller, a rotary grain sorting device that separates the mixed rice hulled by the huller, and a horizontal axis rotating tube provided in the rotary grain sorter. Rotary grain sorting devices mounted on machines are known. The above-mentioned grain sorting device supplies and rotates a mixed rice mixture into a horizontally rotating cylinder with numerous pot holes formed on its inner surface.
The structure is such that brown rice that has sunk to the lower layer is pulled up through the pot hole and taken out into a finished rice receiving trough provided in a rotating cylinder. (Problems to be Solved by the Invention) In order to properly separate the mixed rice using the above-mentioned grain sorting device, the amount of supply from the huller and the condition of the grain layer in the horizontal shaft rotating cylinder are important. More than that, the hulling rate of the hulling section is also an important factor. If the hulling rate is extremely poor and below the average, the mixed rice will have a small amount of brown rice, so the amount of brown rice scooped into the finished rice receiving trough will also decrease, and the amount of unhulled rice in the cylinder will gradually increase in volume. It will eventually get stuck. Ideally, it would be desirable for the hulling rate in the hulling section to always be average and to be supplied without interruption, but it is difficult to do so, and there is no way to know the hulling rate. (Means for Solving the Problems) Therefore, the present invention provides a hulling section 1, a rotary grain sorting device 10 for separating mixed rice hulled by the hulling section 1, and a rotary grain sorting device 10. 10, a detection sensor 26 that can detect the thickness of the grain layer 28 provided on the discharge side of the horizontally rotating cylinder 11, a finished rice receiving gutter 13 provided in the horizontally rotating cylinder 11, and the finished rice receiving gutter. The automatic tilt angle adjustment mechanism 62 of the rotary grain sorting device 10 automatically adjusts the tilt angle by the detection sensor 26 and the brown rice detection sensor 27. The angle adjustment device for a rotary grain sorting device is attached to a hulling device which is formed by linking the automatic inclination angle adjustment mechanism 62, the detection sensor 26, and the brown rice presence/absence detection sensor 27 so as to operate in a consistent manner. It is something. (Example) To explain one example with the drawings, 1 is a hulling section, which has a staking hopper 2 on the upper part;
A pair of hulling rolls 3, 3 are provided at the bottom of the rice hull. A winnowing part 4 is formed at the lower part of the hulling rolls 3, 3. 5 is a suction blower that sucks and removes dusty rice husks in the air sorting section 4, 6 is a mixed rice conveyor, 7 is an unripe rice conveyor, 8 is a mixed rice receiving trough, and 9 is an unripe rice receiving trough. A rotary grain sorting device 10 is provided on the side of the hulling section 1. The case 60 of the sorting device 10 is placed on the machine body, and the lower end of the case 60 on the hulling section 1 side is rotatably attached to the machine body by a horizontal shaft 61.
The lower part of the other end of 0 is attached to the fuselage via an automatic tilt angle adjustment mechanism 62 so that it can move up and down. That is, when the automatic tilt angle adjustment mechanism 62 is operated, the case 6
0 moves up and down about the horizontal axis 61 with respect to the body, and the angle of the case 60 with respect to the horizontal is adjusted. The automatic tilt angle adjustment mechanism 62 includes a shaft 63 that is rotatably attached to the aircraft body, a shaft 64 that is attached to the case 60 and moves up and down with the case 60, and a shaft 64 that is attached between the shafts 63 and 64. an arm 65, a motor 66, opposite gear grooves 67, 67a of the shaft 63, screw tubes 68, 68 fixed to the lower ends of the arms 65, 65, and a gear 70 fixed to the shaft 69 of the motor 66. and a gear 71 fixed to the shaft 63. Inside the case 60, the horizontal shaft rotating cylinder 11 is installed horizontally. Numerous potholes 12 are formed on the inner peripheral surface of the rotary cylinder 11. A finished rice receiving trough 13 is provided inside the rotating cylinder 11. The receiving trough 13 is provided completely in the longitudinal direction within the rotary cylinder 11, and a finished rice conveyor 14 is installed horizontally on the bottom surface of the receiving trough 13. An outlet 15 is formed at the end of the discharge side 72 of the finished rice receiving trough 13.
The lower end of 5 opens onto the finished rice take-out gutter 16. 17
is the finished rice take-out conveyor. A cross section of the finished rice receiving trough 13 is as shown in FIG. 3, and a finished rice regulating valve 19 is installed on the rotation rising side 18 thereof. The lower end of the regulating valve 19 is fixed to a shaft 20, and the angle of the regulating valve 19 is adjusted by rotating the shaft 20. Discharge side 72 of finished rice receiving trough 13
An intermediate shelf 54 and a mixed rice collection gutter 56 are arranged in parallel in the front-rear direction below, and a paddy return shelf 55 is provided below the mixed rice collection gutter 56, with a constant front-to-back interval below the paddy return shelf 55. and the detection sensor 26 is attached. The detection sensor 26 is activated when the grain layer 28 of mixed rice formed in the horizontal shaft rotating cylinder 11 reaches a certain thickness or less on the discharge side 72, and 27 is a finished rice control valve of the finished rice receiving trough 13. A brown rice presence/absence detecting sensor is attached to 19, and the sensors 26 and 27 cause the motor 66 to rotate in the forward and reverse directions. A limit switch 74 is provided at a fixed portion facing the rotary grain sorting device 10 on the lower side of the supply side of the rotary grain sorting device 10. The limit switch 74 and both sensors 26, 27 are connected as shown in FIGS. 5 and 6. A supply gutter 30 is installed in parallel on the descending side 29 of the finished rice receiving gutter 13. A supply spiral 31 is provided within the supply trough 30 . A thrower 32 is installed on the side of the mixed rice conveyor 6.
installed, and the thrower 32 is the rotary grain sorting device 10.
The hopper 33 opens onto a hopper 33 fixed to the end of the feed trough 30 . 52 is a falling tube, and 53 is a current plate. FIG. 5 is a circuit diagram of the automatic control device, and FIG. 6 is an ON/OFF table showing the operation of the motor 66. (Effect) Next, the effect will be described. When the unhulled rice is supplied to the hopper 2, it is hulled by the hulling rolls 3, 3 and falls into the wind sorting section 4, the rice husks are sucked by the suction blower 5, and the mixed rice falls into the mixed rice receiving trough 8. The immature rice falls into the immature rice receiving trough 9. The mixed rice that has fallen into the mixed rice receiving trough 8 is transferred horizontally to the mixed rice conveyor 6 and flows into the thrower 32, which is then raised and supplied to the hopper 33. Hopper 33 is supply gutter 3
Since it is opened at 0, it is sent to the supply side 73 by the supply spiral 31, and is supplied into the horizontal axis rotating cylinder 11 from the falling cylinder 52 at the terminal end. Since the horizontal rotating cylinder 11 is rotating clockwise, the mixed rice forms a grain layer 28 as it rotates, and shifts toward the rotation rising side 18. Since the lower layer of the grain layer 28 is brown rice, the grain that fits into the pot hole 12 is brown rice, which rises as the horizontal rotary cylinder 11 rotates and is taken out to the finished rice receiving trough 13 and conveyed by the finished rice conveyor 14. It moves to the discharge side 72 and falls through the outlet 15,
The finished rice is taken out from the finished rice take-out gutter 16 via the finished rice take-out conveyor 17. However, when the hulling rate becomes low, the horizontal shaft rotating cylinder 1
The amount of brown rice in the grains supplied to the supply gutter 30 of 1 decreases, and the amount of brown rice that is scooped out decreases, so the grain layer 28 in the horizontal shaft rotating cylinder 11 becomes thicker, and the amount of brown rice in the finishing rice conveyor 14 decreases. Become. Therefore, since it is known from both detection sensors 26 and 27 that the hulling rate is low, the motor 66 is operated as shown in the diagram in FIG. The arm 65 is moved in the vertical direction to move the feed side 73 of the rotary grain sorting device 10 upward, thereby suppressing the feed by the feed spiral 31 in the feed trough 30. Then, the roll gap is adjusted automatically or manually. When the hulling rate increases, the amount of brown rice in the grains supplied to the supply gutter 30 of the horizontal axis rotating cylinder 11 increases, and the amount of brown rice scooped increases, so the grain layer 28 in the horizontal axis rotating cylinder 11 becomes thinner. Therefore, the amount of brown rice on the finishing rice conveyor 14 increases. Therefore, both detection sensors 26,
27 indicates that the hulling rate is high, so the motor 66 is operated to rotate the shaft 69 → gear 70 → gear 71 → shaft 63, and the arm 65 is moved in the inclined direction to create a rotary type grain sorting device. Lower the supply side 73 of 10,
The supply by the supply spiral 31 in the supply trough 30 is increased. Then, the roll gap is adjusted automatically or manually. (Effects) The present invention comprises a hulling section 1 and a rotary grain sorting device 10 that separates mixed rice hulled by the hulling section 1.
and a horizontal rotating cylinder 11 of the rotary grain sorting device 10.
A detection sensor 26 capable of detecting the thickness of the grain layer 28 provided on the discharge side of the plate, a finished rice receiving trough 13 provided in the horizontal shaft rotating cylinder 11, and a brown rice detection sensor 26 provided in the finished rice receiving trough 13. Consisting of a sensor 27 and an automatic tilt angle adjustment mechanism 62 of the rotary grain sorting device 10,
The automatic tilt angle adjustment mechanism 62 is connected to the detection sensor 2.
6 and the automatic tilt angle adjustment mechanism 62 so as to be automatically operated by the brown rice presence/absence detection sensor 27.
Since this is an angle adjustment device for a rotary grain sorting device which is attached to a hulling device in which the detection sensor 26 and the brown rice presence/absence detection sensor 27 are connected in a related manner, the presence/absence of brown rice installed in the finished rice receiving trough 13 can be adjusted. The detection sensor 27 can detect the amount of brown rice to be taken out into the finished rice receiving trough 13, and the detection sensor 26 can detect the thickness of the grain layer 28 provided on the discharge side of the horizontal shaft rotating cylinder 11. Since the thickness of the sensor 28 can be determined, the hulling rate, which could not be known in the past, can be determined as described above.
27 to the automatic inclination angle adjustment mechanism 62, the inclination angle of the horizontal shaft rotating cylinder 11 can be automatically adjusted to the optimum state. Furthermore, since the rice hulling rate of the rice hulling section 1, which cannot be known, can be known, the rice hulling section 1 can also be adjusted.
