One end of a connecting member 53 is locked to the upper end of the arm 50, and the other end of the connecting member 53 is locked to an operating unit 54 provided on the walking steering handle 2. The sliding body 46 is formed in a plate shape that is long in the front-rear direction, and the front and rear sides are bent upward.

[0011]

Next, the operation will be described. The present invention has the above-described configuration, and when the traveling wheels 3 are driven by the driving motor 6 to move the aircraft forward, weeding the leafy vegetables in the field by the weeding body 15,
The harvested leafy vegetables are guided by a weeding rod 14 and transported by a transport device 17.
And the root is cut by the cutting blade 16 at substantially the same time as being pinched from the left and right by the conveyor belt 21 of the conveyor 17, and the cut leafy vegetables are conveyed to the end by the conveyor belt 21 as they are. , Falls into the receiving table 40 below the terminal end of the transport device 17, and is manually put into the receiving box 41 by an operator. In the above case, the cutting blade 16 is mounted on the cutting blade frame 30 mounted on the mounting table 32 so that the front and rear positions can be adjusted. The mounting table 32 is mounted on the body frame 1 so that the vertical position can be adjusted. By adjusting the position, the positional relationship between the transport device 17 and the transport belt 21 is made appropriate, and the leafy vegetables are transported to the transport belt 2 of the transport device 17.
1, the mowing can be performed in a pinched state, the mowing can be performed reliably, and since the mowing is performed before the transport of the transport belt 21 of the transport device 17 is started, pulling out can be prevented, and by adjusting the vertical position, it is suitable for a field. Reaping posture.

The transport device 17 is provided so that the transport belt 21 pinches and transports the leafy vegetables from the left and right sides, and has a vertical axis rotation provided on the front side of the main frame 10 inclined forward and backward. Front roller 18 and main frame 1
0, it is wrapped around the rear roller 20 on the horizontal axis provided on the rear side, so even thin and long leafy vegetables are carefully conveyed,
In addition, since the conveyance attitude is changed in the middle, the catching at the end of the conveyance becomes easy. Thus, below the receiving table 40, a supporting table 42 is provided so as to protrude rearward.
Box frame 43 which is rotated and fixed at 180 degrees on the upper surface of 2
Is provided, the receiving box 41 is fitted to the box frame 43, and when the root side of the leafy vegetables is piled high on one side of the receiving box 41, the box frame 43
Is turned to change the direction of the receiving box 41 by 180 degrees, and the root side of the leafy vegetables is thrown into the side where the tip side has been stacked so far. Therefore, leaf vegetables can be put in by effectively utilizing the capacity of the receiving box 41.

A sliding body 46 is provided below the leading end of the main frame 10. The sliding body 46 has its front and rear intermediate portion pivotally attached to the lower end of an arm 47. The arm 47 has a long hole 49 formed in the middle thereof, the pin 51 of the arm 50 is engaged with the long hole 49, and the upper and lower middle portion of the arm 50 is , And one end of a shaft 52 is locked to the upper end of the arm 50, and the other end of the shaft 52 is locked to an operating unit 54 provided on the walking steering handle 2. When the connecting member 53 is operated, the arm 50 rotates about the axis 52, and the pin 51 of the arm 50 moves in the long hole 49 to rotate the arm 47,
The sliding body 46 moves up and down with respect to the body frame 1 and the weeding body 1
5 and the height of the cutting blade 16 are adjusted. In this case, the cutting blade 1
Up and down 6 is performed individually in principle by raising and lowering the cutting blade frame 30, and the cutting height is adjusted by the sliding body 46, but it is of course possible to adjust the cutting height also by the cutting blade frame 30. . Note that the sliding body 46 is configured to move up and down steplessly or a plurality of steps.

Further, since the sliding body 46 is formed in a flat plate shape elongated in the front-rear direction and the front and rear sides are bent upward, the field is covered with a vinyl sheet and the circular holes formed in the sheet are formed. Even if it is a multi-farming method of cultivating crops, it runs smoothly.

[0015]

According to the present invention, a pair of left and right weeding bodies 15 for weeding leafy vegetables such as green onions, green onions, leek, three leaves, etc. are provided at the forefront position on the body frame 1 which is long in the front-rear direction. Grass 1
5 is provided with a transport device 17 comprising a pair of left and right transport belts 21 for nipping and transporting the leafy vegetables while changing the transport attitude in a horizontal direction from an upright position, and a vertical axis rotating at a position below the start end of the transport device 17 The cutting blade 16 is provided, and the end of the transporting device 17 is a leafy vegetable harvesting device such as Chinese chive which is located above the driving traveling wheel 3 provided at the front and rear intermediate position of the body frame 1. Since the cutting blade 16 that rotates in the vertical axis is provided at a position below the start end of the transporting device 17, it is possible to prevent leaf vegetables from being pulled out, and to mow in a state of high commercial value.
Since the cutting can be performed by the cutting blade 16 in the holding state by the transfer device 17, smooth cutting can be performed reliably, and the leaf vegetables are held and transferred while changing the transfer posture in the horizontal direction from the upright position.
