Description

[Detailed Description of the Invention] The present invention relates to a device for discharging residues remaining after sorting in a rotating sorting cylinder for sorting rice.

Conventionally, in this type of discharge, the residue is discharged through a discharge chute provided on the main body into a storage bag brought below the chute, and when the storage bag is filled, it is replaced with the next empty bag. was.

However, this requires a lot of effort to replace the previous bag with the next bag, which is not rational.

The present invention was proposed in view of this point, and aims to simplify the work of replacing bags by providing a distribution gutter in the discharge section.

The present invention will be explained below with reference to embodiments shown in the drawings.
1 is the frame of the main body of the rice sorting machine, and a rotary sorting cylinder 2 having a large number of small through holes is mounted on a shaft inside the frame.

Inside the discharge side of the machine frame 1, a scooping vane 3 is provided to receive rice residue that did not fall and remain in the rotary sorting tube 2 and pump it upwards, so that it is discharged into a discharge chute 4 projecting outward. It is configured.

That is, in this example, the discharge chute 4 forms the discharge section of the present invention, and the inside of the discharge chute 4 forms the discharge path for the residue.

Reference numeral 5 denotes a distribution gutter, which communicates with the discharge path and is open at both ends, and is swingably provided in the discharge chute 4 serving as the discharge section.

In addition, for distribution, a long hole 5d is bored in the center of the gutter 5, and this long hole 5d is connected to a pin 6 that constitutes the support shaft of the present invention.
It is movably locked to.

That is, for distribution, the gutter 5 is arranged in a direction perpendicular to the discharge chute 4, and as will be described later, the discharge operation is performed by tilting it to the left or right as appropriate.

7 and 7' are storage bags for receiving the residue.

During the discharge operation, one bag 7 is brought below one end side 5a of the gutter 5, and then the gutter 5 is rotated by hand around the pin 6 and pushed down.

Then, the distribution of the gutter 5 moves in the tilting direction because the elongated hole 5d is loosely fitted into the pin 6, and in the case of the embodiment shown in FIG. 6 and is locked there.

As a result, the residue is distributed from the discharge chute 4 into the gutter 5, and since this is tilted, it flows only into one end side 5a and is discharged into the bag 7.

Then, before the bag 7 is full, the other bag 7' is brought under the other end side 5b.

After that, when the bag 7 is full, the distribution is performed by rotating the gutter 5 to the other side (Fig. 4), and discharging into the empty bag 7' is started, and the full bag 7 is placed in another place. Take it away.

This evacuation operation is then repeated.

In addition, as shown in FIG. 3, the lower part of the discharge chute 4 is
For distribution, if the gutter 5 is cut diagonally to reduce the gap 8 between the lower surface 5c of the gutter 5 and the lower part of the discharge chute 4, the gutter 5
The tilting angle of the rice can be made relatively large, and there is no possibility that the falling rice will leak from the other end side 5b.

As described above, according to the device of the present invention, it is possible to change bags continuously, and the prerequisite for this work is that the left and right distribution of the gutter 5 is done in a stable manner. Become.

In other words, when the gutter 5 is distributed to the left (Fig. 3), the gutter 5 moves diagonally downward to the left and becomes more biased to the left, and conversely, when the gutter 5 is distributed to the right (Fig. 4) In this case, the deviation to the right increases, so that the distribution balances with the outflow inertia generated when passing through the gutter 5, and the tilting of the gutter 5 is stabilized.

In this example, the position of the pin 6 is distributed below the gutter 5, but it is of course not limited to this position.

Moreover, the size and shape of the gutter 5 and the length of the elongated hole 5d are appropriately selected in consideration of the size of the rice sorting machine and the like.

As explained above, the discharge device according to the present invention has a distribution gutter with a long hole formed in the center, and the long hole is freely engaged with a support shaft perpendicular to the gutter, so that the ejection device can swing freely. Since the system can be tilted stably to the left and right as needed, it is possible to distribute the discharge from the end opening of the gutter to the container installed below, and the discharge operation can be performed stably and smoothly. It is something that can be done.

Furthermore, compared to the conventional single discharge chute, the bag is generally longer than the height of the discharge chute, so conventionally the opening edge of the bag was folded back and then brought to the bottom of the discharge chute. When this is used, the bags are brought to the raised side of the gutter for sorting, so the above-mentioned folding operation is also unnecessary.
