Description

[Detailed Description of the Invention] The present invention relates to an automatic feed amount control device in a paddy coarse sorter.

In other words, in a paddy rough sorting machine, a perforated iron plate and a grain board are installed diagonally on the upper and lower sides so as to be swingable, and a supply hopper is shown above the inclined upper side of the perforated iron plate. Paddy, etc. is supplied from the supply hopper onto the slotted iron, and is shaken and sorted without letting it flow down, and the amount of feed from the hopper side can be controlled so that the layer can be sorted efficiently. The present invention is to provide a system that enables reliable and good sorting at all times and has a simple structure so that it can be carried out suitably.

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

Fig. 1 shows a cross-sectional view of the whole, in which a perforated iron plate 1 is obliquely installed on the inner upper part of the frame A supported by swinging supports 6, 6, and a grain plate 2 is similarly obliquely provided below it. A hopper 7 is formed at the upper inclined end of the perforated steel plate 1, and an eccentric wheel 9 is fitted to one end of an interlocking rod 8 connected to one of the swinging support rods 6. The frame body A is installed so as to be swingable by rotationally driving the eccentric wheel 9 by means of 10, and a container 11 is installed below the inclined lower end of the perforated iron plate 1. A conveying gutter 12 is installed below the drop port 2a at the lower end of the slope, and the structure is similar to the conventional type.

Further, the lower end discharge port 3a of the supply hopper 3 attached to the frame body B is made to look into the upper part of the hopper 7, and the discharge port 3
A lead roller 4 is rotatably installed inside a.
The lead roller 4 is installed so that it can be rotated by a variable speed motor M installed in a frame B via a belt 13.

5 is the middle part of the perforated iron plate 1 in the inclination direction, and this perforated iron plate 1
It is a plate-shaped sensor that is vertically installed perpendicular to the direction of flow of paddy, etc. flowing down on the perforated iron plate 1, slightly lower than the upper end of the plate, and is fixed on one side of the plate-shaped sensor 5. The rotating shaft 14 is installed on the frame A, and the rotating shaft 14 is vertically installed so that when the sensor 5 becomes drooping due to its own weight, the other side 5a comes into contact with the upper surface of the batten iron plate 1. A known speed controller 〇 inserted at one end and the variable speed motor M are connected by a cord 15, and when the sensor 5 comes into contact with paddy etc. and the rotating shaft 14 rotates, the variable speed motor M is connected.
It is configured so that the speed can be changed.

When paddy, etc. harvested by the combine harvester is put into the supply hopper 3, the lead roller 4, which rotates by the drive of the variable speed motor M, feeds out the paddy, etc. and feeds it to the hopper 7. 1 with paddy etc. flowing down.
The paddy is sorted and falls onto the grain board 2 below, one paddy that flows down the grain board 2 falls into the conveyor gutter 12, and the pieces of ears, straw waste, etc. that did not fall through the grain iron board 1 are removed. It continues to flow down into container 11.
can be placed in

At this time, the rice grains, etc., which are to be flowed down the perforated iron plate 1 from the hopper 7, are not evenly distributed over both sides of the perforated iron plate 1 at the beginning of the flow, but when they get close to the plate-shaped sensor 5, they are shaken. The rice grains, etc. in this leveled state act on the plate-shaped sensor 5.

In this state, when the amount of paddy fed out by the lead roller 4 increases and flows in a thick layer on the cut iron plate 1, the sensor 5 is pushed by the layer of paddy as shown in FIG. The rotation of the rotation shaft 14 causes the variable speed motor M to be decelerated via the speed controller C. Therefore, the rotation of the lead roller 4 is decelerated and the amount of feed is reduced, and the layer on the perforated iron plate 1 is Changes to become thinner.

Conversely, when the amount on the perforated iron plate 1 decreases, the sensor 5 operates according to the condition, and the lead roller 4 rotates faster, increasing the amount of supply, and the amount on the perforated iron plate 1 increases. The feeding is done in a constant layer with good sorting.

In this way, the present invention is a paddy rough sorter that consists of a perforated iron plate and a floating grain plate installed vertically and swingably, and a hopper visible above the inclined upper side of the perforated iron plate. In the machine, a lead roller rotatably driven by a variable speed motor is installed at the lower part of the supply hopper, and the lead roller is installed in the lower part of the supply hopper, and the lead roller is installed in the middle of the perforated iron plate in the direction of inclination and slightly lower than the upper end of the perforated iron plate. The structure is such that a plate-shaped sensor perpendicular to the direction is installed to detect the thickness of the flowing layer of paddy, etc., and the rotational speed of the variable speed motor is controlled via a speed controller. When the amount of paddy changes slightly, the sensor immediately detects it and the feed amount can be adjusted while controlling the rotation of the reed roller.The paddy can be fed onto the perforated iron plate in a layer that can be efficiently sorted. In particular, since the sensor is installed vertically in the middle of the perforated iron plate in the direction of inclination and slightly lower than the upper end of the perforated iron plate, it can be detected when the paddy, etc. flowing down on the perforated iron plate is evenly leveled. Since the thickness of the flowing layer is detected by the sensor, accurate detection can be performed.Moreover, since the sensor is plate-shaped and vertically installed perpendicular to the flowing direction, detection is more reliably and smoothly, and sorting is always possible. The present invention has the advantage that it can be carried out reliably and satisfactorily, and that the rotation of the node roller is changed using a variable speed motor, and that it can be suitably implemented with a simple structure as a whole.
