[Detailed description of the invention] (a) Industrial application field The present invention provides a rotatable part by forming a recess on the front part of the wind selection part and a number of depressions on the inner peripheral surface on the rear part. An operating device for a rotary sorting rice huller in which a rotary sorting section is provided with a receiving gutter suspended in a horizontal sorting cylinder, and the removing section and the rotary sorting section are adjacent to each other, and each of these parts is integrated. It is related to.

(b) Conventional technology Conventionally, it has been preferable for stationary working machines such as rice hullers and rice mills to be installed and operated in a horizontal position.
As known from Japanese Utility Model Publication No. 36-20350, a holding means for horizontally correcting the machine body is attached, and for rice milling machines, for example, a horizontal indicator device is attached as shown in Japanese Utility Model Publication No. 36-10256. They checked to see if the aircraft was level and took necessary measures.

(c) Problems to be Solved by the Invention The present invention provides a rotary sorting section comprising a receiving gutter suspended in a sorting cylinder which is rotatably installed horizontally and has a number of depressions formed in its inner circumferential surface. A rotary sorting huller is constructed by integrally forming a removing part and a wind sorting part, and the size and shape of the depression formed on the inner circumferential surface of the sorting cylinder in the rotary sorting part and the sorting cylinder The circumferential speed of the trough and the state of development of both side walls of the receiving gutter, etc., affect the scooping effect of the hollow, that is, the sorting effect. A selection will be made. This appropriate value is selected so that the desired sorting action is performed when the machine is in a horizontal state, and if the machine is not in a horizontal state, it will lead to a defective state. Overall, good results cannot be obtained.

Therefore, in view of the above-mentioned points, the present invention provides a horizontal sensor that detects the horizontal state of the machine body, and makes it possible to supply power to the hulling machine by this horizontal sensor when the machine body is in the horizontal state. In such cases, horizontal sensors are installed at specific locations on the machine wall to accurately detect the inclination of the machine in the front and back, ensuring that the rotary sorting section always performs the normal sorting action, and creating a rotary sorting huller that can be used with peace of mind. It was created for the purpose of providing.

(d) Means for Solving the Problems Therefore, in order to achieve the above object, the present invention provides the following steps: a recess is formed on the front part of the wind selection part, and a large number of depressions are formed on the inner peripheral surface of the rear part. A rotary sorting section is provided in which a receiving gutter is inserted into a sorting cylinder that is rotatably installed horizontally, and the removal section and the rotary sorting section are adjacent to each other, and these parts are integrated into a rotary sorting system. In the sliding machine, the sorting cylinder has its supply side at the rear and its discharge side at the front, and a horizontal sensor installed in the power supply circuit to the electric motor to sense the horizontal state of the machine body. It is provided on the discharge side machine wall, and when the machine body is in a horizontal state, the circuit is connected by the horizontal sensor and can be operated.

(E) Effect With this configuration, if the machine is installed in a horizontal position, the horizontal sensor connects the power supply circuit to the electric motor to enable operation, and when the electric motor is started, normal rice hulling is carried out. If work can be carried out and the aircraft is tilted and not installed in a horizontal position, the horizontal sensor will cut off the circuit and make it impossible to operate.

In that case, since the horizontal sensor is installed on the discharge side machine wall of the sorting cylinder, it is located approximately in the middle of the machine in the longitudinal direction of the whole machine, so that the front part of the machine is high and the rear part is low. Also, even if the front part is low and the rear part is high and tilted, this is accurately and sensitively detected, and the mixed rice flowing from the supply side to the discharge side within the sorting cylinder is retained in the sorting cylinder. This ensures that the scooping action by the recesses is improved without causing the recesses to flow or rapidly shift to the discharge side.

The rice husks and second grains are removed by the removing rolls 2 and removed by the sorting air of the suction machine 3, and the removed rice (mixture of brown rice and paddy) is transferred to the rice thrower 48 The upper sorting cylinder 2 is lifted up through the funnel 47.
It is sent to the supply side X through the transfer gutter 27 of No. 2 and falls into the sorting cylinder 22.

This fallen rice is transferred to the discharge side Y while flowing due to the scooping action of the recess a of the sorting cylinder 22 which rotates while being supported by the wheels 24, 24. Scooping up paddy and receiving trough 28
Supply troughs 49, 50 perform primary sorting.
From there, it flows into the supply side X in the lower sorting cylinder 23 and undergoes secondary sorting. The sorting action in the lower sorting cylinder 23 is similar to that in the upper sorting cylinder 22, but it is adjusted so that only brown rice is scooped up into the receiving gutter 32 by the depression a.

In the case of the upper sorting cylinder 22, as mentioned above, the sorted material scooped up into the receiving gutter 28 is brown rice and some paddy, and in the case of the lower sorting cylinder 23, the sorted material is scooped up into the receiving gutter 32. In order to ensure that only brown rice is scooped up, the upright posture of each adjustment plate 54, 55 is adjusted to change the upward unfolding condition.

The paddy that has not been scooped up by the upper sorting cylinder 22 is returned from the discharge side Y end to the paddy tank 1 as shown by the arrow A in Fig. 1, and undergoes removal again. 1 part of the brown rice and 1 part of the paddy that were not scooped up in step 23 flow down as shown by the arrow RO, join with new dropped rice, and are lifted up by the dropped rice thrower 48, and the sorting action is repeated. The brown rice scooped into the receiving gutter 32 of the lower sorting cylinder 23 flows down from the discharge side Y in the direction of arrow C, and the fine dust contained in the brown rice is removed by the suction wind, and the brown rice is transferred to the brown rice thrower 56. From then on, it will be taken out to a suitable location outside the machine.

However, if the aircraft is not installed horizontally, the weight 52 will hang down in the state shown by the imaginary line in FIG. does not start.

In that case, the horizontal sensor P is installed along with the switch S on the discharge side Y left machine wall of the sorting cylinders 22 and 23, and is located approximately in the middle of the entire machine in the longitudinal direction. When the front section is high and the rear section is tilted low, or when the front section is low and the rear section is tilted high, in both cases, the amplitude of the weight 52 is maximized, accurately and sensitively detecting the tilt, and the sorting cylinder is Since the electric motor 7 will not start unless the horizontal state of the cylinders 22 and 23 in the longitudinal direction is ensured, the sorting cylinder 2
The material fed to the supply side X of Nos. 2 and 23 does not stagnate or rapidly transfer to the discharge side Y, and the scooping action by the recess a is improved for sorting.

(g) Effects of the Invention As explained above, the present invention provides a rotatable horizontal arrangement by forming a recess on the front part of the wind selection part and a number of depressions on the inner peripheral surface on the rear part.
