Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention relates to an onion conveying device, which arranges the stems and leaves of the onion in a downward direction 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 outer periphery of the pair of conveyance rollers in the axial direction, and a large number of elastic protrusions are formed on the outer circumference of the pair of conveyance rollers between the elastic string-like bodies. A protruding structure 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 retained by the elastic protrusions, and the onion is transferred to the pair of conveyance rollers. The onions are introduced between the containers, and in this state, the onions are delivered to the delivery end.

(Problems to be Solved by the Invention) According to the structure in which a large number of elastic protrusions are protruded from the outer periphery of the pair of conveyance rollers between the spiral string-like bodies as described above, the large number of elastic protrusions are formed on the spiral string-like bodies. Because the onion leaves are separated from the body, depending on the length of the onion leaves, the leaves may not be caught 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 spaced apart from the spiral strings and protrude between the spiral strings. 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 has been made in view of these points, and it is possible to prevent onions from being damaged and to reliably feed the stems and leaves below between a pair of conveying rollers, and to provide a method for feeding the onions. An object of the present invention is to provide an onion conveying device in which elastic protrusions are not damaged or cut off by stones, and in which a large number of elastic protrusions are attached so that they can be easily attached and detached. It is.

A number of elastic protrusions are detachably provided at predetermined intervals in the length direction of the conveying protrusion, and are provided with a large number of elastic protrusions that engage the onion stems and leaves and guide them downward from the interval between the pair of conveying rollers. This is what I did.
