Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The present invention relates to an onion conveying device, which arranges the stems and leaves of the onion downward while conveying the onion dug up by an onion harvester. Regarding things to be carried out.

(Prior Art) Conventionally, this type of onion conveying device, as described in Japanese Patent Publication No. 52-46851, consists of rotating a pair of conveying rollers inwardly at an appropriate interval. The shafts are freely parallel to each other, an elastic string-like body is spirally wound around the axial outer periphery of the pair of conveyance rollers, and a large number of elastic protrusions are protruded from the outer circumference of the pair of conveyance rollers in this elastic string-like body. The structure established is known.

Then, as the pair of conveyance rollers rotate, the onion is conveyed by the spiral elastic string-like body of the pair of conveyance rollers, and the onion stems and leaves are tied up by the elastic protrusions, and then the pair of conveyance rollers The onions are introduced between the containers, and the onions are transported to a single transport section in this state.

(Problem to be solved by the invention) According to the structure in which a large number of elastic protrusions are provided protruding from the outer periphery of a pair of conveyance rollers between the spiral string-like bodies as described above, the large number of elastic protrusions are Because the onion leaves are separated from the body, depending on the length of the onion leaves, the leaves may not be held up by the many elastic protrusions and may not be introduced between the pair of conveyor rollers. The problem is that there is a lack of certainty that it will lead downwards. In addition, the large number of elastic protrusions are separated from the spiral string-like bodies and are prominently formed between the spiral string-like bodies. Therefore, there is a problem that a large number of elastic protrusions are damaged or cut off. Furthermore, providing a large number of elastic protrusions independently protruding from the outer periphery of the pair of conveyance rollers not only requires a lot of effort, but also poses a problem of lack of stability.

Therefore, the present invention was developed in view of these points, and it is possible to reliably feed the onion leaves between the pair of conveying rollers, and prevent the elastic protrusions that feed the onion leaves from being damaged by stones. It is an object of the present invention to provide an onion conveying device which prevents the onion from being cut and damaged and which allows the large number of elastic protrusions to be easily and stably suspended.

[Structure of the idea]

(Means for Solving the Problems) The onion conveying device of the present invention has a pair of conveying rollers that are rotatably arranged in a row, with an interval between them for introducing onion stems and leaves, and which are rotated inwardly. An elastic conveying protrusion is provided in a helical manner on the outer periphery of the pair of conveying rollers in the length direction to guide the onion between the pair of conveying rollers and conveying the onion in the longitudinal direction. A large number of elastic protrusions are integrally provided at predetermined intervals on the rear edge of the elastic conveyance protrusion to lock the onion leaves and guide them downward between the pair of conveyance rollers.

(Function) According to the onion conveying device of the present invention, the pair of conveying rollers are rotated inwardly, and when the onion is carried onto the pair of conveying rollers, the onion is moved by its spiral elasticity. The onion leaves are moved between a pair of conveyance rollers by the conveyance ridges and conveyed in the conveyance direction, and the onion stems and leaves are retained by a large number of elastic protrusions protruding from each of the elastic conveyance ridges. The onion is then guided and conveyed downward between a pair of conveyance rollers, so that its posture is adjusted, and its stems and leaves are introduced between a pair of conveyance rollers, suspended downward, and conveyed to the discharge end.
