DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art A conventional onion harvester has an unreasonable arrangement of a traveling device, a device for causing a stem to cause onion stems, and a digging blade for digging onions.

[0003]

Therefore, depending on the onion growing condition in the field, the excavation and harvesting operation cannot be performed smoothly, and the operation efficiency cannot be improved.

[0004]

The present invention employs the following technical means in order to solve such problems. That is, in front of the traveling device provided at intervals in the lateral direction, a digging blade provided forward and downward so that the front end is located below the rear end, and a ruler wheel located on a front extension line of the traveling device. A leaf stem raising device having a lug that rotates in the lateral direction on the side of the action start side and then linearly moves upward and rearward to cause the action of the onion leaf stem portion is provided. The leaf cutting device that cuts the onion leaves and stems by making the ground inclination angle formed by extending the linear movement of the onion larger than the ground inclination angle of the engraving blade causes the engraving blade and the onion leaf stems An onion harvester characterized by being provided at a position higher than an operation start end of a rug that performs an operation.

[0005]

The onion in the field is harvested by an onion harvester that is moved by the drive of the traveling device 1. At the time of this harvest, the onion leaf stem pivots laterally at the action starting end side, and then continues. The onions are stretched upward by the lugs moving straight upward and the roots of the onions are dug up by the digging blades 8 having a small inclination angle to the ground, which fall forward. Also, the onion leaf stem is cut by a leaf stem cutting device,
Separated from root.

[0006]

According to the present invention, since the onion leaf stem is stretched by a lug having a large inclination angle to the ground, the boundary between the leaf stem and the root becomes clear, and there is no problem such as the leaf stem cutting device cutting the root. . And since the diving blade is lowered forward and has a small inclination angle with respect to the ground, it can enter the ground with a small resistance, and the driving force for moving the aircraft forward can be reduced. Furthermore, since the leaf cutting device is provided at a position higher than the starting end of the rug that causes the excavating blade and the onion leaf stem, there is no hindrance to the excavating operation by the engraving blade. Even if the rug is brought close to the ground, the leaf-stalk cutting device does not enter the ground, and poor cutting of the leaf-stalk can be eliminated.

[0007]

Embodiments of the present invention will be described below. The undercarriage 2 has the traveling device 1, and a ruler wheel 10 is provided on a front extension line of the traveling device 1 at a front lower position. The traveling device 1 is provided at intervals in the lateral direction.

[0008] The leaf stem raising device 3 has a raising lug 7, and a pair of left and right sets constitutes two rows,
The leaf stem cutting device 4 is provided with a reciprocating type cutting blade at a lower position behind the raising device 3 and at a position higher than an operation start end of a digging blade 8 and a lug 7 for causing a leaf stem portion of the onion. I have.

The leaf-stalk conveyor 5 comprises a driving roller 11 and a driven roller-1 which are inclined rearward and upward in a wide belt conveyor in the rear of the cutting device 4 over the entire width of the chassis 2.
It is wound between two.

The engraving blade 8 is provided at the front downward so that the front end is located below the rear end. The front edge is below the leaf stem raising device 3 and below the center of the ruler wheel 10 in the lateral direction. It is configured to dug onions. In addition, in the side view of the fuselage, the inclination angle to the ground formed by extending the linear movement of the lug is set to be larger than the inclination angle to the ground of the digging blade.

The leaf stem cutting device 4 extends downward from the transmission box 9 on the undercarriage 2 from the front to the bottom, and is provided with a crank device at the end of the transmission shaft 6 penetrating through the hollow of the leaf stem discharge conveyor 5. 13 is provided and driven by a drive lot 14 connected to the crank device 13.

As described above, the transmission shaft 6 can be linearly provided without being diverted by penetrating the hollow portion of the foliage discharge conveyer 5, so that not only the configuration is simple but also the transmission efficiency is improved. Have good characteristics.

Further, the transmission shaft 6 is connected to the leaf stem discharge conveyor 5.
(Belt conveyor), so that troubles such as entanglement of cut leaf stems do not occur. If the transport projection is provided on the surface of the leaf-stalk discharge conveyor 5, the leaf-stem can be reliably locked and transported.

Reference numeral 15 denotes a guide, which can surely guide the cut leaf stem onto the leaf stem discharge conveyor 5.
Reference numeral 16 denotes a rotating body, which is provided between the pair of leaf stem raising devices 3 in a brush shape, and scrapes the leaf stems stuck on the both raising devices 3 onto the conveyor 5.

It is to be noted that the leaf stem discharge conveyor 5 may be configured such that the leaf stem can be extended at the time of the cutting action of the leaf stem to assist the cutting by making a steep inclination as shown in FIG.
