Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic toto gutter angle control device for a sorting plate for sorting mixed rice such as paddy and brown rice.

A rice huller equipped with a conventional oscillating sorting plate has a Watato gutter fixedly attached to the oscillating sorting plate, which transports the material to be sorted, which is a mixed grain of paddy and brown rice, and performs the oscillating sorting. There is a type that supplies it to the board. In this type, when the inclination angle of the oscillating sorting plate is adjusted depending on the distribution of paddy and brown rice on the oscillating sorting plate, the Toto gutter, which is integrally fixed to the oscillating sorting plate, The inclination angle of the conveyance direction of the grain conveyance direction changes, and the grain conveyance capacity of the Watato gutter changes, which has an adverse effect on the sorting performance.

This invention maintains the conveying inclination angle of the Wato gutter that transports and supplies the materials to be sorted to the rocking sorting plate constant even if the inclination angle of the swinging sorting plate changes, thereby stabilizing the conveyance amount of the Wato gutter. This is an attempt to improve measuring and sorting performance.

Embodiments of the invention shown in the drawings will be described below.

Okay, let me explain the configuration.

1 is a rice hulling machine, and this rice hulling machine 1 has a dehulling section 2, a dehulling section 2
A paddy supply funnel 3 for supplying paddy to rice, a wind sorting section 4 for sorting out the rice that has been removed from the agitation section 2, an elevator 5 for frying the rice that has been removed from the agitation section 2,
It is composed of a swing sorting section 6 and the like.

To explain the swing sorting section 6 in more detail, the swing sorting plate 7 is supported swingably by links 8 in a state of being tilted in the front-rear direction and left-right lateral direction, and the links 8...
8 is configured so that reciprocating rocking can be learned using a well-known rocking device (not shown). Also, one link 8
is configured such that its position can be freely changed and adjusted in the vertical direction, and the inclination angle of the oscillating sorting plate 7 can be adjusted to change the rainbow.

Reference numeral 9 denotes a Watato gutter which supplies the mixed rice supplied from the mixed rice supply funnel 10 to the rocking sorting plate 7 after being oscillated together with the rocking sorting plate 7; A Toto gutter rack 11 is attached to the other end of the Toto gutter 9 along the vertical direction, and the swinging sorting plate 7 is rotated forward and backward by an electric motor (not shown). A pinion 12 that can be rotated is engaged. By rotating this pinion 12 in the normal or reverse direction, the inclination angle of the todo gutter 9 in the conveying direction can be adjusted.

13 is a Toto gutter angle sensing sensor; this Toto gutter angle sensing sensor 13 is installed along the conveying direction on the Toto gutter 9 side;
3 is a mercury ball 13a, a sensor cylinder 13b in which the mercury ball 13a can move, and a sensor cylinder 13;
It is constructed of switches 130 and 13 (l) which can be opened and closed by mercury bulbs 13a at both ends of b.
When the mercury bulb 13a moves to the left inside the sensor tube 13t and the switch 13C is closed, the electric motor (not shown) rotates in the forward direction. , the left side of the Watado gutter 9 is raised, and the inclination angle becomes gentle 1, and the mercury bulb 13a is moved to the sensor cylinder 1.
3b to the right, close the switch 13d, reversely rotate the electric motor (not shown), and lower the left side of the todo gutter 9 to maintain an appropriate conveyance inclination angle. When the Toto gutter angle sensor 13 is held horizontally, the mercury bulb 13a is located in the middle of the sensor cylinder 13b, and both switches 13 (3 and 13d) are in an open state, and the electric motor (
(omitted from the drawings) is stopped, and the toto gutter 9 remains fixed to the swinging sorting plate 7.

Next, the effect will be explained.

When carrying out hulling work, paddy is supplied from the paddy supply funnel 3 and dropped into the dehulling section 2.The dehulling action of the dehulling section 2 causes the rice to slide off and fall into the wind sorting section 4. Fall. The washed rice is passed through the wind sorting section 4, where light hulls are discharged from the dust exhaust pipe 15 to the outside of the machine, and heavy hulls and brown rice fall downward and are supplied to the mixed rice supply funnel 10 through the elevator 5. This mixed rice is further added to Totohi9.
The rice is then supplied to a plurality of superimposed oscillating sorting plates 7, and the oscillating sorting plates 7, which are swinging back and forth, sort the rice into brown rice, mixed rice, and paddy. In this way, the mixed rice is subjected to the sorting action on the oscillating sorting plate 7'', but the degree of dryness of the paddy,
The distribution condition on the oscillating sorting plate 7 changes depending on the product type, etc.
The sorting work is efficiently carried out by adjusting the tilt of the swinging sorting plate 7 and positioning the objects to be sorted over the entire swinging sorting plate 7.

When the inclination angle of the swing sorting plate 7 is made steeper by adjusting in this way, the mercury bulb 13a of the sensor cylinder 13b moves to the left, closing the switch 13C, and causing the electric motor (not shown) to rotate in the forward direction. Then, by moving the left side of the Toto gutter 9 upward to maintain the conveyance inclination angle of the Toto gutter 9 at a predetermined state, and with the swinging sorting plate 7 tilted low, the mercury bulb 13a is placed in the sensor tube. Move the body 13b to the right side and press the switch 13 (
1 is closed, the electric motor (not shown) is rotated in the reverse direction, the Toto gutter rack 11 is moved downward, the conveyance inclination angle of the Toto gutter 9 is adjusted to a predetermined state, and the swing sorting plate 7 is removed from the Toto gutter 9. It is possible to maintain a substantially constant supply amount of materials to be sorted, thereby improving work efficiency and maintaining a stable sorting state.

In addition, in the embodiment, the Toto gutter angle sensing sensor 1 is installed in the Toto gutter 9.
3 is installed in a horizontal state so that the conveyance inclination direction of the Toto gutter 9 is almost horizontal. The conveyance inclination angle of the gutter 9 may be in an inclined state, and the sensor integrated 1 of the Wato gutter angle sensing sensor 13 may be
'3.1) is a linear cylinder, but the sensor cylinder 1
The middle part of 3b may be curved downward. Further, the inclination angle of the swing sorting plate 7 may be adjusted manually or automatically.

This invention has the following advantages: (A watato gutter 9 for conveying and supplying the objects to be sorted to the swing sorting plate 7 is attached to the swing sorting plate 7 whose mastication angle can be adjusted, and the carrying angle can be adjusted. Since this is an automatic toto gutter angle control device for a sorting plate configured to be able to adjust the conveyance angle of the toto gutter 9 in relation to the adjustment of the inclination angle of the toto gutter 7, even if the inclination angle of the swinging sorting plate 7 changes, The conveying inclination angle of the Watado gutter 9 is adjusted in response to the change in the inclination angle, thereby making it possible to maintain efficient sorting work and stable sorting performance.
