Description

[Detailed description of the invention] The present invention relates to an automatic feed control device in a paddy rough sorter.

In other words, the paddy is placed in a rough sorter, which consists of a swinging sorting body having a sorting plate such as a perforated iron plate, with a supply tank visible above one end of the feed end, and then the rice flows over the sorting plate and is sorted. The flow of coarse material can be reliably detected near the end of the sorting plate, and the amount of feed from the supply tank can be adjusted according to the detection, and the amount of sorted material can always be adjusted to the appropriate amount to improve sorting performance. The purpose of this invention is to improve the efficiency of sorting.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a cross-sectional view of the paddy coarse sorter, and (A) is the sorting body;
A sorting plate (a) made of perforated iron plate is installed above the sorting plate (a), and a grain-flowing plate (5) is installed in parallel below the sorting plate (a).
A hopper (6) is integrally formed above one end side of the sorting plate (a) which becomes the supply end (a), and the sorting plate (a)
A discharge port (7) is formed behind the terminal end of the flow board (5), and a downward discharge port (8) is formed at the terminal end of the grain flow board (5).

The lower opening (2) of the supply tank (1) supported by the machine frame 1151 is visible above the hopper (6), and the inner side VC of the lower opening (2) is connected to the supply tank (]j A variable speed motor (4) is rotatably equipped with a leet roller (3) that can feed out the coarsely selected material, and is supported on the machine frame (15).

61, and a variable speed motor (41) is connected to a control box (1?l). There is a sorting body (A) above the middle part in the longitudinal direction.
Support frames +181 and +19+ are installed horizontally to connect to both upper sides of the sorting board (a), and sensors (S) (S2) connected to the control box (171) are installed in the center of the support frames +181 and +191, which are in the center of the width direction of the sorting board (a). are respectively installed, and both sensors (S 2 ) and (S 2 ) are configured to be able to detect the flow of coarse material on the sorting plate ja) by optical ultrasonic waves or electrostatic type.

In addition, both sensors (SIXS→
If both IXS 2) do not detect a flow, the variable speed motor (4) is controllably installed so as to change the speed to a high speed and slowly rotate the lead roller (3).

Incidentally, if the upper intermediate sensor (S2) detects it, but the terminal sensor (Sl) does not detect it, the speed change motor does not change the rotation speed.

It is also possible to use both sensors (SI) 2) as sensors for detecting flow rates, and configure the control box (1) to change and control the rotational speed of the variable speed motor (4) depending on the detected flow rates. Ru.

During the work, the raw material in the supply tank (1) is transferred to the lower sorting body (A) by the rotation of the leet roller (3).
The paddy is fed by a V-shaped feed and is sorted while flowing on the oscillating sorting plate (a), and the leaking paddy is taken out from the discharge port (8) by flowing the grain plate (5), and the remaining small amount is The straw waste and the like flow down on the sorting plate (a) without leaking from the sorting plate (a) and are discharged from the IT outlet (7).

In this state, both sensors (S 1) (S2) are connected to the sorting plate (
a) The flow of coarse material flowing down the soil will be detected,
When the amount decreases and the flow stops near the terminal end on the sorting plate, both sensors (S) will not detect it and the rotation of the variable motor (4) will be increased and the IJ troller (3) will be activated. While rotating quickly, it is possible to increase the amount of material fed onto the sorting plate (a), and conversely, the amount of coarse material on the sorting plate (a) becomes too large and is directly discharged from the terminal end. When the condition is reached, both sensors (S2) are activated to detect and reduce the rotation of the variable speed motor (41) and reduce the amount of feed onto the sorting plate (a) while rotating the lead roller (31) slowly. It is possible to adjust the supply amount so that the liquid always flows down to the terminal end of the sorting plate (a).

As described above, the present invention provides a rice grain sorting machine which is configured with a supply tank visible above one supply end side of a swinging sorting body having a sorting plate such as a perforated iron plate, and a rice grain sorting machine that has a sorting plate such as a perforated iron plate and has a supply tank that is visible above the supply end side of the swinging sorting body. A lead roller is mounted on the shaft, and the lead roller is rotatably mounted by a variable speed motor, and above the terminal end of the sorting plate and above the middle part in the longitudinal direction, there is a flow of coarse material on the sorting plate. Since it is equipped with a sensor that can detect the speed change motor and drive the variable speed motor accordingly, both sensors can reliably detect the flow of the coarse material flowing on the sorting board and be sorted, and the system can adjust the flow according to the flow condition. This means that the feed rate can be adjusted by controlling the rotation of the leet roller using a variable speed motor.
It is possible to improve the sorting performance by always appropriately adjusting the flow condition onto the sorting plate, and to perform efficient sorting.
