DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic sludge husk and unnecessary leaf removing device for green onions, which strips and removes the sludge husk from the white roots of the harvested leeks and removes unnecessary leaves and dead leaves from the leaves. About.

[0002]

2. Description of the Prior Art Sludge adheres to harvested green onions, and unnecessary substances such as dead leaves adhere to the harvested green onions. The removal operation conventionally performed generally is roughly as follows. That is, first, the leaves of green onions are gripped by hand, and a pressure medium such as compressed air or high-pressure water is jetted to the white roots to remove sludge and peel the outer skin. next,
The peeled white root side is gripped, and unnecessary leaves and unnecessary dead leaves adhering around the leaves are manually removed.

[0003]

The above-mentioned conventional method of peeling and removing green onions requires that the green onions be grasped by hand, and that the white roots and the leaves be further switched halfway, resulting in poor workability. In addition, there is a problem that work efficiency is poor due to intermittent work. In addition, sludge and unnecessary leaves are scattered during the operation, causing a problem that the sludge and the unnecessary leaves adhere to the operator, and also cause a problem that the entire workplace is soiled. In addition, when the onions that have been peeled and removed have to be carried into the next process, manual operations are required, and there is also a problem that they are not arranged in an orderly manner.

As a means for solving the above problems, an automatic removing device for automatically removing sludge husks and unnecessary leaves of green onions has been conventionally used.
No. 049 gazette. This "onion sorter"
The middle part of the onion, which is transported mounted on the conveyor, is sandwiched by the first sandwiching belt, and the root of the onion is peeled, washed, and muddy with the compressed air and water injected from the nozzle. Then, the root portion of the onion is nipped by the second nipping belt, compressed air is jetted to the leaves to remove unnecessary leaves, and is transferred to the flattening belt for accumulation. It is also characterized in that the leaves are lifted by using an inclined round belt in order to prevent the leaves from sagging when unnecessary leaves are removed.

[0005] According to the above-mentioned known technique, the sludge skin and unnecessary leaves of onion are automatically removed, but there are the following problems. First, since the green onions to be thrown in have a leaf portion spread, if there is a drop between the flat conveyor and the first holding belt, the green onions often move to the first holding conveyor side in an inclined posture. Therefore, the holding posture of the green onions held by the first holding belt is not uniform, and there is a possibility that sludge removal at the root portion may be incomplete. Next, in this apparatus, compressed air or water is injected into the root in a posture where the root is held by the first holding belt to remove sludge skin and peel the skin.However, the adjustment is performed when the root is misaligned with the nozzle. Since the means is not taken into consideration, a portion of the sludge crust that has not been removed is apt to be generated, and conversely, compressed air or water may be excessively applied, and a necessary portion may be removed. In addition, there is a problem that waste of compressed air and water occurs. In addition, since the leaves hang down while the root is held horizontally, there is also a problem that the onions are bent. Furthermore, there is no consideration regarding fine adjustment of the positional relationship between the leaves and the compressed air injection nozzles for the removal of the unnecessary leaves from the leaves, and the removal of the unnecessary leaves becomes insufficient. There is a problem.

[0006] Green onions carried into the apparatus are generally put in a state in which a plurality of green onions are put together. In the case of relatively thick green onions, there is no particular problem, but in the case of soil cultivated green onions, the roots of the roots of the white roots are entangled with each other, forming an entangled part of a complicated shape . As described above, the loaded green onions need to remove the sludge rind attached to the white roots. However, in order to remove the sludge rind attached to the entangled portion, high pressure and a large amount are required. Then, it is necessary to separate or cut the entangled portion and remove the sludge after spraying the pressure medium. In this case, it is necessary to control the pressure of the pressure medium and the amount of spraying, and it is necessary to adjust the spraying position, so that there has been a problem that the work is not sufficiently stabilized or ensured. Further, if the pressure of the pressure medium and the spray amount are not appropriate, there is a problem that the white roots of the green onions are broken and the green onions are defective. Furthermore, in the case of thick soil cultivation onions, even if the base end side of the white root is slightly cut, the entangled portion is not sufficiently removed, and as a result, the sludge skin is incompletely removed. Was.

The present invention has been made in order to solve the above-mentioned problems, and only the sludge husks and unnecessary leaves of green onions are automatically and reliably removed, and the transfer posture is not disturbed. Even if various sized onions are thrown in, the sludge husks and unnecessary leaves of the onions can be produced in a short time by removing the sludge husks and unnecessary leaves that are necessary and sufficient. It is an object to provide an automatic removal device. Also,
In particular, it is not necessary to adjust the pressure of the pressure medium and the amount of spraying on green onions having a entangled portion at the base end side of the white root portion, no destruction of the white root portion occurs, and the sludge skin is completely removed. It is an object of the present invention to provide a sludge husk for green onions and a device for automatically removing unnecessary leaves.
