Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a circulation assisting device for mobile agricultural machinery such as a single-wheel rice transplanter, seeding machine, or fertilizer spreader.

(b) Prior Art Conventionally, many single-wheel mobile agricultural machines are known, and they usually have a handle at the rear of the machine.

(c) Problems to be solved by the invention Generally speaking, when a two-wheeled mobile agricultural machine rotates, if the side clutch of the inner wheel is disengaged, the inner wheel becomes a fulcrum and the drive force of the outer wheel allows the machine to rotate easily. can be done.

However, since single-wheel mobile agricultural machines only have a single drive wheel, they can move relatively easily when the soil surface is dry, but in wet fields they must be moved around by hand. As a result, their work efficiency decreased and they became extremely fatigued.

(d) Means for solving the problem The present invention is a one-wheel mobile agricultural machine that has one wheel pivoted in the center of the width of the machine and a handle at the rear. It is pivoted so that it can move up and down, and when the aircraft is rotating, it rotates downward and touches the ground.
The above-mentioned problem was solved by using this resistance rod as a fulcrum.

(e) Function When the machine is moving while the machine is running, the resistance bar is rotated upward and retracted upward, and when the machine is rotating, the resistance bar is rotated downward and touches the ground. It becomes a fulcrum, and you can rotate around it while driving one wheel.

(F) Embodiment To explain a single-wheeled rice transplanter shown in the drawing as an embodiment of the rotation assisting device for a mobile agricultural machine according to the present invention, 1 is an engine installed at the front, and a transmission is installed at the side. A transmission case 6 of the planting device 5 is attached to the rear of the transmission case 2, one side frame extending rearward from the outside of the transmission case 2 and the engine 1, and the other side frame 3 in which the transmission mechanism is installed. A single wheel 8 is pivotally supported on the other output shaft of the transmission case 2 via a chain case 7.

The planting device 5 includes a seedling platform 9 which is laterally reciprocated by the transmission case 6, and a seedling platform disposed in front of the platform 9, which scrapes seedlings one by one from the notch of the apron 10 and plants them on the rice field. It consists of a pair of left and right planting rods, and left and right handles 11, 11 are attached to the rear of the transmission case 6, and floats 12, 12 are attached to the left and right sides, respectively.

On both sides of the front lower part of the transmission case 6, there are bosses 16, 16 having resistance rods 13 projecting diagonally rearward and downward and arms 15 projecting upward.
is rotatably supported by support shafts 17, 17, and a boss 2 loosely fitted into the support shafts 18, 18 provided at the rear thereof.
0 and 20, petals 21 and 22 protruding rearward and upward at approximately right angles and a short arm 23 are provided, and this arm 23 is interlocked and connected to the front arm 15 by a rod 25, and the upper end of the arm 15 and the lower end of a support arm 30 hanging down from the transmission case 6 are connected by a toggle spring 26.

In the above-mentioned single-wheel rice transplanter, when performing planting work while moving the machine forward, the left and right resistance rods 1
3 in the ascending position as shown by the dotted line in Figure 1, and when turning the aircraft after one stroke of planting, depress the lower petal 21 on the side that will be the turning center, and the resistance rod 13 will move as shown by the solid line. As shown, it rotates downward and penetrates into the mud, supporting the center of rotation of the aircraft.On the other hand, since the wheels 8 are driven, it can be easily rotated with a small turning radius. This resistance rod 13 guards the apron 10 in a raised state.

In addition, instead of the petals 21, 22, switching levers 27, 27 are attached to the left and right handles 11, 11 so as to rotate back and forth, as shown by chain lines in FIG.
The switching levers 27, 27 are connected to the arm 1.
5 and 15 with wires 28 and 28, and a return spring that biases the arms 15 and 15 upward is attached. When one of the switching levers 27 is tilted forward during planting work, the wire 28 is relaxed and the resistance rod 13 is raised to the position shown by the dotted line by the return spring, and when the switching lever 27 is pulled backwards and pushed down, the arm 15 is pulled backwards and the resistance rod 13 is rotated downward and the aircraft is rotated. It becomes the fulcrum of

Furthermore, in the above-mentioned embodiment, a single-flower rice transplanter was explained as an example of a mobile agricultural machine, but the present invention is also applicable to a fertilizing device or a seeding device in which a scraping roller is pivotally supported at the bottom of a tank, or other types of devices. The same method as in the above-mentioned embodiments can be applied to mobile agricultural machinery such as a single-wheel fertilizer applicator and a single-wheel seeding machine.

(g) (Effects of the invention) As mentioned above, the present invention is a one-wheel mobile agricultural machine that has one wheel 8 pivoted in the center of the width of the machine and a handle 11 at the rear. The resistance rod 13 is pivotally supported so that it can move up and down, so that when the aircraft rotates, it rotates downward and touches the ground. Therefore, when the resistance rod 13 is rotated downward when the aircraft rotates, 13 serves as a fulcrum to support the side of the fuselage, and by driving the wheels 8, there is no need to forcibly pull the handle 11 around, and the small turning radius prevents fatigue while making it extremely light and easy. can be rotated to
