1 to 3 show an embodiment of the present invention. Aircraft 1
A seat 22 is provided near the center of the vehicle, and an operation box 23 having steering wheels, various operation levers, and necessary instruments is provided in front of the seat 22. The prime mover 6 is provided below the seat 22,
The traveling of the harvester and the driving of the harvesting device are performed.

[0008] Behind the seat 22, there is provided a storage tank 21 for head vegetables 5 covering almost the entire width of the body, for storing harvested products,
In addition, it is structured so that the harvest can be taken out from the rear door. The rear traveling wheels 7 driven by the prime mover 6 and the front traveling wheels 7 operated by the steered wheels respectively straddle the ridge with left and right wheels, and cause the body 1 to travel along the ridge.

At the front left and right of the body 1, both ends of the upper and lower links 10 having the same length are pivotally connected to the front 9 and the rear 8 of the frame to form parallel links. The frame 31 is formed by 9 and 8 after the frame. The frame 31 is pivotally connected to the body 1 at a pivot point between the frame rear 8 and two links 10 forming a parallel link, and a hydraulic cylinder 27 bridged between one end of the long lower link 10 and the body 1. Accordingly, the frame 31 can be rotated in a vertical plane with respect to the body 1.

The front frame 9 and the rear frame 8 are each formed of a square pipe and the other is formed of a square shaft which penetrates and slides into the square pipe, and is cut into a square shaft portion by the rotation of a pinion 25 driven by a motor 24. 26 to move the frame 3
1, the locking pin 28 for pivotally connecting the frame 31 to the body 1 pulls the frame 31 toward the body 1 at its head, and the slide pin 29 , One end is fixed and inserted through a hole in the rear frame,
It is possible to expand and contract.

The rear end of the dielectric 2 is attached to the front 9 of the frame by a swing fulcrum pin 12 so as to be swingable in a horizontal plane, but is pressed by left and right compression springs 11 on the dielectric projection 19 to be substantially constant with respect to the frame 9. Stop at the related position. One front end of the derivative 2 forms a V-shape that opens forward.
A cutting device 3 is provided at the end of the V-shaped groove, and is driven via a chain case 13 attached to the guide 2.

A carrier 4 having a starting end above the cutting device 3
Is composed of two transport belts 14 on the left and right, a transport pulley 15, a transport drive pulley 16 for driving the transport belt 15, and a transport frame 17 supporting these. The transport frame 17 is connected to the chain case 13 by a connecting link 18. Concatenated,
Derivative 2 around carrier fulcrum 30 provided after frame 8
Rocks with the tip of the.

When harvesting the head vegetable 5, the harvester is positioned such that the center of the head of the head vegetable 5 coincides with the center of the V-shaped opening of the derivative 2 on the left side with respect to the strip on which the head vegetable 5 grows.
The height of the tip of the derivative 2 from the ground surface is determined. In the case of double-row harvesting, the motor 25 is rotated so that the center of the V-shaped opening of the derivative 2 on the right side is aligned with the center of the head vegetable 5 on the right growth strip, and the tip of the right derivative 2 is moved.

During harvesting, the harvester may be operated so that the tip of the derivative 2 is mainly aligned with either the left or right strip. As the harvester moves forward, the stem at the lower center of the head vegetable 5 reaches the V-shaped groove,
When the stem deviates from the center line of the V-shaped groove, the stem of the head vegetable 5 such as cabbage that slides in contact with one side of the V-shaped groove is strong. Is pivoted about the pivot pin 12.

When the derivative 5 guided to the stem of the head vegetable 5 continues to move forward while repeatedly swinging, the stem of the head vegetable 5 reaches the bottom of the V-shaped groove of the derivative 2 and is set there. The sheet is cut by the cutting device 3, sandwiched by a carrier 4 having a starting end above, and conveyed rearward and upward. The head vegetables 5 taken over by the upper carrier 20 at the end of the carrier 4 are stored in the storage tank 21 provided at the rear of the machine 1. After cutting the stem, the derivative is returned to its original position by the force of the compression spring 11 and is ready for the next harvest.

4 to 7 are different from the above example in the shape of the formed portion of the V-shaped groove at the tip of the derivative 2. When harvesting the head vegetable 5, it spreads out of the head part and contacts the ground. The leaf is harvested, the outer leaf is lifted as the derivative 2 advances, and the head is wrapped so that the head is wrapped. The outer leaf is used as a protective material to prevent damage to the crop due to sliding and vibration during transportation and transportation. In addition, it has an effect of preventing complications such as the outer leaves remaining in the field being rotten and foul-smelling, and propagation of various bacteria in the soil.

Referring to FIG. 4, the shape and operation of the left and right triangular pyramids forming the V-shaped groove at the tip of the derivative 2 will be described. The tip of the pyramid hangs down slightly into the ground,
Scoop the outer leaves that spread on the ground. The mutually opposing slopes of the triangular pyramid form a concave surface as shown by the cross-sectional designating lines (a to e) depending on the position from the tip, and the lower ridge is almost parallel to the ground and mutually triangular pyramid. The V-shaped groove is formed, but the ridgeline of the upper side becomes higher as the head vegetable goes backward, gradually pushes up the outer edge of the outer leaf, and when it reaches the f-section, the lower half of the head vegetable 5 wrapped in the outer leaf It shows a curve almost similar to the shape of the head, and the outer leaves envelop the head vegetables.

The front part of the bilaterally symmetrical ski-shaped derivative forming an arc-shaped scooping curved surface corresponding to the shape of the vegetables can be replaced with one conforming to the shape and size of the vegetables.
