Description

[Detailed description of the invention] This invention relates to a vegetable harvester.

Conventional vegetable harvesters of this kind have a structure in which a pulling belt holds the leaves of vegetables pulled up from the soil and transports them in a suspended state, while cutting between the roots and leaves with a cutter. .

According to this configuration, the vegetables in the suspended state are tilted by the pressing force when the cutter comes into contact with the vegetables.
It had the disadvantage of not being able to cut accurately.

In contrast, the present invention provides a lifting conveyor that holds the leaves and lifts the carrot upward from the soil, and a root holding conveyor that grips and conveys the carrot root from the lifting conveyor. and a cutter with a guide, which is located above the root holding conveyor and moves up and down guided by the upper surface of the root, so that it can hold the carrot root and transport it in a stable state. The cutter guided by the shoulder (top surface) of the carrot allows the leaf to be cut just close to the shoulder of the carrot, and the cutting accuracy of the leaf can be significantly improved compared to conventional methods. has.

Embodiments of the present invention will be specifically described below with reference to the drawings.

First, we will discuss its configuration.

The machine body 1 has running wheels 2, and is provided at the front with a lifting conveyor 3 that grasps and pulls up carrot leaves from the soil.

The root holding conveyance bodies 4, 4' are configured to have a narrow lower part and a wide upper part to match the shape of the carrot, so that the carrot can be conveyed while holding the root part between the legs.

The cutter 5 is rotatably attached to the lower part of a drive shaft 8 which is extendable and retractable and is mounted on an inner shaft of an outer cylinder 7 which is extendable and has a spring 6 on its outer periphery.

The guide body 9 is located above the root holding and conveying bodies 4, 4', and has a long guide hole 10 into which the carrot leaf part enters, and is configured to move up and down integrally with the cutter 5.

In short, the cutter 5 moves up and down as the guide 9 is guided by the shoulder of the carrot.
It has a structure that allows it to move up and down.

Reference numeral 11 denotes a shooter, which is configured to drop carrot roots from which leaves have been cut.

12 indicates a training wheel.

Next, its effect will be explained.

When the machine 1 is advanced into a carrot field, the leaves of the carrots are held by the starting end of the pulling and transporting body 3, and the carrots are pulled up and sequentially transported upward.

The carrots are transported with their roots held by the root-holding transport bodies 4, 4', and advance by pushing up the guide 9 with their shoulders.

Then, the cutter 5 moves upward together with its derivative 9, and cuts the leaf part just close to the shoulder of the carrot.

The roots are then dropped onto the field by the shooter 11.

In this way, when the carrot is positioned so that the guide member 9 comes into contact with the shoulder part of the root part, the vertical position of the cutter 5 is determined, and the leaf part and the root part are cut as described above.

As described above, the present invention provides a lifting conveyor that holds the leaves and lifts carrots upward from the soil, and a root holder that grips and conveys the carrots from the lifting conveyor so as to receive the carrots. A carrier;
Since it is composed of a cutter with a guide that is located above the root holding carrier and moves up and down guided by the upper surface of the root, the carrot leaf can be cut almost to the shoulder of the root. Cutting accuracy can be improved.

Therefore, it has an excellent effect of maintaining the commercial value of carrots.

Note that similar effects can be expected even when this invention is used to harvest vegetables other than carrots.
