Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harvester for storing several bulb-bearing vegetables having bulbs, such as onions and garlic, in a bundle.

[0002]

2. Description of the Related Art Conventionally, a technique for binding and storing headed vegetables dug up from the ground has been known. Its structure is that the neck, which is the upper part of the bulb of the bulb vegetables, is conveyed backward by sandwiching it with a conveyor, and is inherited by a stationary conveyor that drives the bulb vegetables intermittently, and when a certain number of bulb vegetables are brought in, The upper part of the bulbs is bound by the binding device, and then the stationary conveyor is driven to convey the bulbs to the storage container.

[0003]

However, in the prior art, a sensor is used to detect that a fixed number of headed vegetables have been placed on the placement type conveyor. A counter is required to recognize and becomes expensive. In addition, some vegetables are divided into a plurality of leaf parts and may not be detected depending on the transportation state, and it is difficult to accurately detect the number of the vegetables. Therefore, the vegetables are not always bundled into a certain number. In addition, it is difficult to maintain the posture of the headed vegetables in a fixed direction when they are collected on the placement type conveyor, and the positions of the leaves to be bound are displaced, resulting in an unbalanced posture.
Therefore, there has been a demand for a harvester having a configuration in which the number of bindings is constant and the binding posture is stable.

[0004]

The present invention uses the following means in order to solve the above problems. That is, a vegetable harvester that pulls out the headed vegetables and arranges a binding device at the rear of the sandwiching transfer device that conveys the headed vegetables to bind and collect a certain amount of headed vegetables, below the binding device. A rotary plate having a plurality of guide holes for inserting vegetables and arranged obliquely, a leaf portion guide for guiding the foliage portion toward the center of rotation above the rotary plate, and rotating integrally with the rotary plate. A push-up plate provided with a protrusion that closes the guide hole is provided, and the bulb vegetables are inserted into the guide hole and then bundled, and the push-up plate is raised to push out the bulb vegetables to be dropped and accommodated. A sensor for detecting that the final headed vegetable has been inserted is disposed above the guide holes of the plate, and the sensor is configured to detect that the headed vegetable has been inserted into all the guide holes.
