Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a vegetable harvester that mainly harvests vegetables having foliage such as ginger and onion.

[0002]

[Prior art]

 Conventionally, there has been a technique of providing a pulling-out conveyor for sandwiching and pulling up the foliage of vegetables, providing a cutter for cutting foliage, and cutting and separating the foliage to collect vegetables.

[0003]

[Problems to be solved by the invention]

 In the conventional technique, a cutter is provided at a position lower than a position where the foliage of the vegetables is held by the conveyor, and the foliage is cut shorter than the holding position by a cutter. In the case of bundling, the hard part of the middle part of the vegetable foliage is sandwiched between the conveyors, so that the length of the foliage remaining after cutting with a cutter tends to be shorter than the length required for bundling. In order to leave the foliage of the required length for the vegetable, it was necessary to clamp the soft part on the tip side of the foliage of the vegetable more than the middle of the foliage, and there was a problem that the pulling action of the vegetable was likely to be unstable. .

[0004] As disclosed in Japanese Patent Publication No. 59-39084 or Japanese Patent Application Laid-Open No. 53-7444, there is a technique for separating the foliage of vegetables. However, after removing the foliage, the vegetables are dug out. It was not possible to easily pick up or bind vegetables using the foliage.

[0005]

[Means for Solving the Problems]

 Therefore, the present invention provides a vegetable harvesting machine including a conveyor for lifting and transporting vegetables to the ground, providing a cutter for cutting foliage on the conveyor, and providing a discharge member for releasing the foliage of vegetables cut by the cutter. In the above, the cutter is attached to a vegetable holding portion of the conveyor at an intermediate portion of the conveyor, the vegetables are held by the conveyor, and the foliage of the vegetables is cut and separated by the cutter. The discharge end of the discharge member is extended outward on one side, and the cutter at a higher position than the conveyor can cut and remove the soft part on the tip side of the foliage of the vegetable, and the lower half of the foliage is hard. Vegetables can be lifted on a conveyor while leaving the parts, and the hard part of the foliage of vegetables is left as long as it is necessary for workers to pick up In addition to simplifying collection work and improving post-processing workability such as washing with water, it is possible to leave a hard part of the foliage to a length that allows the bundling of vegetables by utilizing the foliage. Vegetables can be easily tied using the remaining foliage of the vegetable, and the hard part between the middle and the root of the foliage of the vegetable is clamped by a conveyor to stably pull out the vegetable to a predetermined height. In addition, it is possible to easily prevent the foliage discharged from the discharge end of the discharge member from dropping on the upper surface of the ridge or the upper surface of the machine body during harvesting.
