Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotational rice transplanting device. Conventionally known rice transplanting devices include a four-wheeled riding type, a two-wheeled walking type, a two-wheeled walking type, and other types. In the riding type and the two-wheeled walking type, the phenomenon of the aircraft falling to the left or right rarely occurs, but since the -wheeled walking type has -wheels, unless you firmly hold the handle with both hands, it is unlikely that the aircraft will fall left or right. There were times when I would flip over to my side.

In particular, when you are planting while moving forward, even if you let go of one hand, you will be relatively stable and will not fall over, but when you make a U-turn at the final point, you will inevitably tilt the aircraft, so If you don't firmly hold both handles with both hands and firmly support the aircraft, it will tip over.

Therefore, the ideal structure for a wheel-type rice transplanting device is to move forward at a speed that is easy to walk and optimal for planting when moving straight, and to automatically turn when making a U-turn. It is best to reduce the speed to a low speed that is easy to use.

Therefore, the present invention provides a walking-type one-wheeled rice transplanting device with one wheel, and a transmission device capable of switching the running speed between high speed and low speed, and a walking control handle of the rice transplanting device is provided with the handle. Equipped with an operating lever that can be operated while holding the
A rotational rice transplanting device, which connects the operation lever and the transmission, and is provided with a restriction mechanism that prevents the transmission from shifting even if the operation lever is operated to an arbitrary position, and
A walking-type single-wheeled rice transplanting device with one wheel is equipped with a transmission device that can switch the running speed between planting speed and turning speed,
Further, the walking control handle of the rice transplanting device is provided with an operating lever that can be operated sideways with a handle like a brake lever of a bicycle, and the operating lever and the transmission device are shifted to a turning speed by grasping the operating lever. A single-wheel rice transplanter is provided with a device that connects the rice transplanters with a wire so that the wires do not act on the wire, and the rice transplanter is equipped with a planting clutch, and the planting clutch and the operating lever are connected to each other by a wire. The gist of this is the configuration of a single-wheel rice transplanter that is constructed by interlocking and connecting the following.

To explain with a diagram, l is a fuselage, and a NiJ engine 2 of the fuselage l is provided. Reference numeral 73 designates a transmission case, in which the front end of the transmission case 4 is fixedly or pivotally attached to the Mitsushi rear case 3 so as to be movable up and down, and the axle 5 is made to protrude sideways from the rear end of the transmission case 4. Install wheel 6.

The body 1 extends rearward on both sides of the wheels 6, and is provided with a planting device 7.7 and a seedling tank 8 at its rear end. 9 is a transmission case. Reference numeral 10 denotes a pair of left and right walking control handles, which are attached to the rear end of the body l. 11.

A protrusion 13.13 projecting upward is provided nearer to the rear than the middle of 112, and the protrusion 13, l3 is pivotally attached to the body l by a shaft 14. At the front ends of the side floats 11.12, each lower end of a float link 15.16 is attached to a shaft 17.
It is pivoted by 18. The float link 15.16 has a vertically long elongated hole 19 into which a pin 20.21 protruding from the fuselage l is inserted.

Therefore, FIG. 5 shows the power transmission aM11, and 2
2 is an output shaft of the engine 2, 23 is an intermediate shaft provided in the vicinity thereof, 24 is a transmission shaft also provided in the vicinity thereof, 2
Reference numeral 5 designates a running latch shaft which is also provided in the vicinity thereof, a gear 26 is fixed to the output shaft 22, a gear 27 and a gear 28 that mesh with the gear 26 are fixed to the intermediate shaft 23, and a gear 27 and a gear 28 which mesh with the gear 26 are fixed to the intermediate shaft 23. A gear 29 that meshes with the gear 28 is fixed.゛In addition to the gear 29, the transmission shaft 24 has a planting gear (?11
J speed gear) 30 and a turning gear (low speed gear) 31 are loosely fitted at a predetermined interval, and a planting gear (high speed gear)
A clutch 3 is installed between the 30 turning gears (low speed gears) 31.
2 are fitted to be slidable in the axial direction.

33 is a gear that meshes with the planting gear 30, 34 is a gear that meshes with the turning gear 31, and 35 is a running latch, all of which are attached to the running latch shaft 25. 36 is a gear fixed to the axle 5, and a wheel 6 is fixed to the axle 5.

The speed change shaft 24 is extended, and a planting clutch 37 is provided. 38 is a gear loosely fitted to the speed change shaft 24;
39 is a gear that meshes with the gear 38, and 40 is a shaft of the gear 39. A beher gear 41 is provided on the shaft 40. 42 is a bell gear, 43 is an intermediate shaft, and 44 is a lead cam shaft.The steering handle IO is provided with a lever 45 like a bicycle brake lever that can be operated while gripping the steering handle IO. A wire 46 has one end connected to the lever 45, and an arm 48 is attached to the other end of the wire 46 via a spring 47. 49 is a return spring.

The arm 48 is fixed to a shaft 50, and a shifter 51 is fixed to the shaft 50. The shifter 51 is engaged with the latch 32 marked with #.

A rotating piece 55 is fixed to the upper part 59 of the wire 46, and the base of the rotating piece 55 is fixed to a shaft 54 provided in the vicinity thereof.

The base of a lever 56 as a limiting member is fixed to the base of the rotating piece 55, and the lever 56 engages with a guide groove 57 of an operation plate 58. The guide groove 57' has a part A and a part B, and when the lever 56 engages with the A part, the outer 59 becomes loose and no longer functions as a wire.6 When the lever 56 engages with the B part, the outer 59 is in a predetermined position. position and begins to function as a wire.

Next, we will discuss the effect.

Start the engine 2, enter the field, and engage the running latch 35 with the gear 36 without gripping the lever 45. The shifter 51 rotates clockwise as shown in FIG. meshes with the planting gear 30. Also,
The wire 52 leading to the planting crafter 37 is loosened, and the planting latch 37 is engaged with the gear 38 by the spring 53. Therefore, the output shaft 22→gear 26→gear 27→gear 28→gear 29
→ Gear shift shaft 24 → Clutch 32 → Planting gear 30 → Gear 3
The rotation is transmitted as follows: 3 -> running rattachi 35 -> gear 36 -> wheel m5 -> wheel 6, and the -wheel type rice transplanter moves forward at the speed of being placed horizontally.

On the other hand, transmission shaft 24 → planting clutch 37 → gear 38 → gear 39 →
The rotation is transmitted from the shaft 40 to the bevel gear 41 to the bell gear 42 and the intermediate shaft 43, causing the planting part w7 to perform planting, and the lead cam shaft 44 to rotate to move the seedling tank 8.

When he reached the final point, he grabbed the steering wheel 10 and lever 45.
When you squeeze it, wire 46 → spring 47' → arm 48 → shifter 51
→The clutch 32 is disengaged from the planting gear 30 and meshes with the turning gear 31. Therefore, the turning gear 31→
Rotation is transmitted as follows: gear 34 → running latch shaft 25 → running latch 35 → gear 36 → axle 5 → wheel 6, resulting in a slow turning speed. Also,
The planting clutch 37 is moved by the wire 52, the planting clutch 37 and the gear 38 are separated, and the planting part is interlocked and stopped.

A rotary piece 55 is fixed to the upper part 59 of the wire 46, and the base of the rotary piece 55 is fixed to a shaft 54 provided in the vicinity thereof.
Since the base of the lever 56 of the limiting member is fixed to the base of the lever 56, when the lever 56 is moved along the guide groove 57 of the operation plate 58 and engaged with the part A, the outer 59 loosens and becomes a wall wire. It stops functioning. Therefore, even if the 8-45 malfunctions during the planting operation, it can be prevented from suddenly slowing down and disrupting the planting interval.

As already mentioned, conventionally known rice transplanting devices include four-wheel riding type, two-wheel walking type, -wheel walking type, and other types. Although this phenomenon rarely occurs, in the -wheel walking type, because the -wheel is □, if the handle is not held securely with both hands, it may turn over to the left or right.

In particular, when planting while moving forward, it is relatively stable and will not fall even if you let go of one hand, but when making a U-turn at the final point, you will inevitably tilt the aircraft, so If you don't firmly hold the handles with both hands and firmly support the aircraft, it will tip over. Therefore, the ideal structure for a wheel-type rice transplanter is that when moving straight, it moves forward at a speed that is easy to walk, and when making a U-turn, it automatically decelerates to a speed that is easy to turn. It would be nice if it were done□
It is.

Therefore, the present invention provides a walking-type rice-transplanting device having only one wheel 6, a transmission device capable of switching the running speed between high speed and low speed, and a walking control handle of the rice-transplanting device. 10 is provided with an operating lever 45 that can be operated while holding the handle lO, and the operating lever 45 connects 8-45 and the transmission, and even if the operating lever 45 is operated to any position, the shifting does not occur. A one-wheel rice transplanter equipped with a limiting mechanism that prevents the device from changing speed, and a walking-type one-wheel rice transplanter with one wheel 6 are equipped with a transmission device that can switch the running speed between the planting speed and the turning speed. Further, the walking control handle 10 of the rice transplanting device is provided with an operating lever 45 that has a handle like a brake lever of a bicycle and can be operated sideways. 45
A single-wheel rice transplanter is connected by a wire 46 so that when the handle is squeezed, the turning speed is changed, and a device is attached to the wire 46 so that the wire 46 does not act, and the rice transplanter is equipped with a planting clutch 37. Provided, the planting clutch 37
and the operating lever 45 are interlocked to form a wheel-type rice transplanting device, so when entering the field, the lever 45 is not held, but the running latch 35 is moved by the gear 36.
When the clutch 32 is engaged with the planting gear 30 due to the elasticity of the return spring 49, the wire 52 leading to the planting clutch 37 is loosened, and the planting clutch 37 is connected to the planting gear 30.
This meshes with the gear 38, and the -wheel type rice transplanting device reaches a layer at the planting speed. After reaching the end point and gripping the control handle lO, when the lever 45 is squeezed, the clutch 32 is moved to the planting gear 30.
It is further disengaged and meshes with the turning gear 31, resulting in a slow turning speed. Furthermore, when the lever 56 is engaged with the section A along the guide groove 57 of the operating plate 58, the outer 59 becomes loose and no longer functions as a wire. It is possible to prevent the planting interval from being disturbed due to sudden slowdown.
