Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention is directed to a single-wheel type rice transplanter, fertilizer applicator, or sowing J! The present invention relates to an accompanying device for the movement of aircraft, etc.

(b) Prior Art Conventionally, when a wheeled type mobile agricultural machine is accompanied by a machine, the machine is kept tilted toward the center of rotation by grasping the handle with both hands.

(c) Problems to be solved by the invention In the known mobile agricultural machine, the heavy and unstable body must be kept tilted toward the center of rotation during the machine rotation operation. Moreover, they were extremely fatigued because they had to repeatedly rotate the aircraft every time they completed work in one direction.

(d) Means for Solving the Problems The present invention provides a mobile agricultural machine having wheels in the center of the machine body and floats arranged on both sides, in which each of the floats is supported so as to be movable up and down, and the floats are operated. By linking the device so that the outer float descends when the aircraft is turning, the aircraft can be kept in a stable state by the wheels, the float on the center of rotation (inner side), and the lowered outer float when the aircraft is turning. The above-mentioned problems were solved in a supportive manner.

(E) Function When the machine is turned along the ridge where one stroke of work is completed in order to move on to the next stroke, when the outer float is lowered using the operating device, the machine tilts toward the center of rotation. Even in this state, the machine body whose central part is supported by wheels is supported on both sides by left and right floats, and it is possible to carry out simultaneous operations extremely easily without having to hold the machine body in an inclined state with both hands.

(F) Embodiment To explain a one-wheel type rice transplanter as shown in the drawings, an embodiment of the present invention is shown in the drawings.
The planted transmission case 3 and the handle 4.4 at the rear are connected to the transmission cylinder frame 5 by left and right frame rods 6, 6 to form an integrated frame, and the wheels 7 are located in the center of the width of the machine. The wheels 7
The floats 10 and 10 placed on both sides of the rear part are planted at the planting depth aI! A link 12.12 is pivotally supported on a single-section lever 11.11 so as to be tiltable up and down, and is connected in a dogleg shape at the front.
It is connected to the frame rods 6, 6 by.

Further, an arm 13 erected at the front of the chain case 8
is connected to the hydraulic cylinder 15, and the hydraulic cylinder 15
The pump 1B connected to has a valve.

The actuating arm 14 of this valve is connected by a connecting rod 18 to a sensing float 17 mounted on the front center of the machine so that it can move up and down, so that when the machine goes up or down due to the height of the tiller, the sensing flow follows. H? swings up and down, the valve is switched and the hydraulic cylinder 15 is operated, which causes the wheels 7 to move up and down to maintain the aircraft at a substantially constant height.

A lever panel 20 is fixed between the left and right handles 4, 4, and has a locking part in the middle and on the left and right sides, and the middle part of the balance rod 22 is pivotally supported on the f part by a fulcrum shaft 21. An operating lever 8-23, which is pivotally attached to the center of the balance rod 22 so that it can only be tilted back and forth, is inserted into the guide groove of the lever panel 20, and left and right float wires 24a connected to both sides,
24b is the connecting bin 12a of the link 12.12,
12a through a metal fitting 25.25 with a long hole.

Further, as shown in FIG. 6, a bottle 26 protrudes from the middle part of the operating arm 14 of the valve to both sides. The locking portion at the lower end of the valve wire 30.31 connected to both ends of the balance rod 22 is connected to the elongated holes 28b, 28b above the plate 28.28, and the front end is A knob 33 at the rear end of the rod 32 connected to the ring 27 is engaged with a receiving plate 35 erected in front of a seedling stand 34 that reciprocates from side to side.

In the rice transplanter described above, when the planting clutch is engaged to drive the seedling stand 34 and the planting rods 38.38, and the running latch is engaged to rotate the wheels 7, the planting rods 313.3
Step 8 scrapes the mat seedlings on the daikaidai 34 one by one and plants them on the river surface.

When one stroke of planting is completed, the planting device is stopped by grasping the planting stopper 37, and the operating lever 23 is tilted in the rotating direction 1, for example, to the left as shown in FIG.
The right side, that is, the outer float wire 24a is connected to the balance rod 22.
As a result, the outer connecting pin 12a, which was in the automatic state as shown in FIG. 1, is pulled rearward as shown in FIG. 2, so the link 12 extends and the float 10 on that side As a result, the machine body is tilted as shown in FIG. 11, and in this state, the handle 4.4 is pushed laterally to rotate the machine easily and quickly.

At that time, the aircraft has wheels 7 in the center and floats 10 and 1 on both sides.
Since it is supported by 0, there is no need to maintain the aircraft in an inclined position, and it is sufficient to simply perform the same operation.

In addition, when the 8-23 is tilted by the above operation, the balance rod 22 pulls the outer valve wire 30, so the lower end plate 2
8 tilts the actuating arm 14 upward via the bin 26;
The valve switches to the upward side, and the hydraulic cylinder 15 extends and pushes down the wheel 7, causing the aircraft to move -1:
R.

Therefore, when the operating lever 23 is tilted in the rotating direction when the aircraft is rotating, the aircraft will tilt toward the center of tilting and rise, and when the operating lever 23 is returned to the neutral position at the center after the rotating, The float 10 that had been descending became free, and the action of tilting the 4j11 body disappeared, and the operating arm 14 also became free, and the sensing float 17
It will be linked to the rise and fall of the

Also, during the planting operation, the operating lever 8-23, which is always tension-biased rearward by the spring 38, is engaged with the intermediate locking part, so that the lever 22 is fixed as shown in FIG. The float wire 24a is in a substantially horizontal position as shown in FIG.
24b and valve wires 30 and 31 are not pulled, and the knob 33 is set to the automatic position (lowered position), the hydraulic cylinder 15 is activated based on the sensing result of the sensing float 17, and the aircraft is lowered relative to the ground. The height is controlled to be approximately constant.

Further, when driving on the road, when the knob 33 is pulled rearward, the ring 27 rotates the actuating arm 14 to the upward side, so that the wheels 7 are lowered and the body becomes an elevated Y-island.

Furthermore, the floats 10, 10 may be tilted up and down centering on the front part, or may be raised and lowered as a whole, as long as the body tilts to the opposite side when a part or all of them descend. .

FIG. 10 shows another embodiment, in which the frame rod 6.6
A 〈-shaped operating rod 39.
2 and 12, the float wire 24a or 24 is lowered by tilting the operating lever 23.
When b is pulled, the bending part 39 of the operating rod 39 of -force
Since a pushes down the front part of the float IO, the fuselage tilts to the opposite side as in the previous embodiment.

(G) Effects of the Invention The present invention provides a mobile agricultural machine having wheels 7 in the center of the machine body and floats 10 and 10 on both sides thereof as described above. The floats 10.
Since the outer float 10 is connected to η so that it descends when the aircraft is turning, when the operation device is operated when the aircraft is turning to move on to the next step after completing the -stroke, the outer float 10 descends and pushes up that side of the aircraft, tilting one aircraft in the turning direction and moving one aircraft to the left and right flow 1-10.
! As a result, the operator does not have to maintain the tilted attitude of the aircraft while holding the handle with both hands as in the past, and it is extremely easy for the operator to accompany the aircraft, allowing him to work for long periods of time. It can significantly reduce fatigue when
