With this harvester, onions can be easily and assuredly cut into stems/leaves and roots, conveyed, and housed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mulch onion harvester.

[0002]

2. Description of the Related Art There are currently no onion harvesters for mulching. As a technique to cut off both ends of onion
0398, and Kaikaihei 4-136096.

[0003]

Although there are techniques for cutting off the end portion, none of them satisfy the function of a harvester. When harvesting onions for mulching, artificially pull them out and arrange them in a line in a forward bending posture, then scoop them one by one.
I am working on cutting roots and foliage. These are laid back and forward, very hard labor tasks. The use of scissors requires a certain amount of power, which is a painful task for weak women and the elderly. Also, it took a lot of manpower, and it was a difficult task just to collect skilled people.
The problem to be solved by the present invention is to make it possible to easily cut the root portion and the foliage without causing heavy labor due to the posture of falling back and advancing.

[0004]

In the present invention, a means for solving the problem is to provide an onion pedestal for artificially raising the ball portion, and a transport device and a tractor for circulating and forwarding from the front to the rear. It is composed of a foliage cutting device for further cutting the foliage through the drive shaft, a root cutting device for cutting the root part, and a storage box for dropping and sliding the sliding plate from the transport device.

Here, for cutting the root part, a blowing device for directing the root part upward and a vertical movement device for the cylinder by sensing a sensor for the height difference of the onion are provided.

[0006]

According to the present invention, the ball portion is placed on the front side of the onion pedestal, and when it is brought closer to the endless chain side of the onion pedestal, it is circulated and forwarded by the ball pushing member of the endless chain. Be transported. At this time, the foliage hangs down and the root moves in an umbrella-like state. And
The root is directed upward by the blower nozzle, and the position of the hair clipper is set by the sensor, and the root is cut. The foliage is cut by a foliage cutting device at a predetermined position close to the ball, and then the sliding plate is dropped and stored in a storage box.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described with reference to the drawings. The present invention (1) is attached to a rear part of a main body frame (3) which is attached to a rear part of a riding type agricultural tractor (not shown) by a three-point link functioning as a lifting means. A pair of left and right wheels (B) are attached to. Further, a detachable tow attachment fitting (33) is attached to the rear portion of the frame, and a storage box (2) is attached.

A control panel (18), a compressor (13) and a generator (12) are arranged on the frame. The sensors are arranged at predetermined intervals on the columns (24) on the frame, and are sent as signals to the control panel by the detection of each sensor. The control board operates the cylinder (15) based on this signal. Thereby, the electric hair clipper (16) fixed to the cylinder cuts the root portion at a predetermined position of the height of the ball portion.

The upper part of the sensor is covered with a cover (26) to prevent direct sunlight from entering. Further, the shape of the upper part of the nozzle is such that the blown airflow is directed upward.

During transportation, the balls are on the top, so the foliage is on the bottom and the root is hanging like an umbrella. Blower nozzles (25) are attached at a predetermined interval in order to turn this upward.

The output shaft of the tractor and the drive shaft (4) of the main body (1) are connected by a detachable coupling, and the rotary blade (8) is rotated by the V pulley (31) via the gear box (32). ing. The pulley (30) is attached to the drive shaft, the endless chain pulley (29) is driven by the V belt (36) to drive the endless chain shaft (28), and the endless chain is circulated.

The onion pulled out by the worker on the seat plate is placed on the onion receiving stand (7) and the endless chain is circulated and moved. The endless chain (19) of the transfer device is provided with attachments (20) at predetermined pitches, and onion pushing metal fittings (21) are attached thereto. The moving onion has the ball up and the root is cut with a hair clipper, and the foliage is cut with a rotary blade. The cut onion drops the sliding plate (11) and is stored in the storage box (2).

The operation of the cylinder of the root cutting device according to the above embodiment will be described below. The air cylinder is equipped with a sensor switch and stops at a predetermined position.

When the onion is detected by the sensor (23) of height L1, the cylinder stops at the position of height L1 + a.

When the onion is sensed by the sensors (23) of the heights L1 and L2, the cylinder stops at the height of L2 + a.

Sensors of height L1, L2, L3 [23]
When the onion is sensed by, the cylinder stops at the position of L3 + a height.

When the ball portion is below the height L1 of the sensor (23), the cylinder stops at the position of the height L1 + a.

As a method of mechanically cutting the root portion, as shown in FIG. (6), the position is fixed by four shafts (34), and an electric hair clipper (16) is attached to a spring (35) and vertically moved. You can also

By attaching a rooting machine, it can also be used for cutting balls for alley cultivation. The electric hair clipper is a known technique. The present invention is not limited to the above embodiment.

[0020]

According to the present invention, the onion placed on the onion cradle is surely conveyed with the ball portion upward by the onion pushing metal fitting, and the root portion and the foliage are cut to a predetermined size. And
Since it is stored in a storage box, it is not necessary to sit down and cut one by one with scissors while walking, and you can harvest onions without heavy labor.
