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 wheeled walking type, and other types. In the four-wheeled riding type and the two-wheeled walking type, the phenomenon of the aircraft falling to the left or right rarely occurs, but in the -wheeled walking type, due to the wheels, the handle cannot be held securely with both hands. There were times when I would turn around 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. 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 rice transplanting device with wheels is that it moves forward at a speed that is easy to walk when going straight, and automatically decelerates to a speed that makes it easy to turn when making a U-turn. It is good.

Therefore, the present invention provides a walking-type one-wheeled rice transplanting device having one wheel, in which a walking control handle of the rice transplanting device is provided with an operating lever that can be operated while holding the handle,
A wheel-type rice transplanting device in which the operating lever and a transmission are interlocked, and the rice transplanting device is provided with a transmission that can switch between a planting speed and a turning speed, and a recessive control of the rice transplanting device is provided. The handle is provided with an operating lever that can be operated sideways by holding the handle, the operating lever is connected to the transmission, and the operating lever has a dual mechanism structure like a bicycle brake lever. A single-wheel rice transplanter, and a single-wheel rice transplanter in which the control lever is set to the planting method if not operated, but turns to rotation speed when operated, and the planting clutch of the rice transplanter is also controlled by the control lever. To explain the structure of a one-wheeled rice transplanting device in conjunction with the following figure, 1 is a body, and an engine 2 is provided at the front end of the body 1. Reference numeral 3 denotes a transmission case, to which the front end of a transmission case 4 is fixed or pivoted, an axle 5 is projected from the rear end of the transmission case 4, and one wheel 6 is attached to the axle 5. 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. 10 has a pair of left and right walking steering handles,
It is attached to the rear end of the body 1. 11.12 are the left and right side floats, and the side floats 11.12
A protrusion 13.1 that protrudes on the upper blade slightly closer to the rear than the middle of the
3 is provided, and the protrusion 13.13 is pivotally attached to the body 1 by a shaft 14. At the front end of side float 11.12,
The lower end of each float link 15.16 is glued to the shaft 17.18. The float link 1516 has a long slot 19 between the upper and lower blades, into which a pin 20.21 protruding from the body 1 is inserted.

In Fig. 5, 22 is the output shaft, 23 is the intermediate shaft, and 24 is the transmission shaft 2.
4.25 is the launch shaft that runs, and the output shaft 22 has a gear 26.
Alternatively, a gear 27 and a gear 28 are mounted on the intermediate shaft 23, and a gear 27 and a gear 28 are mounted on the gear shift shaft 24.
A gear 29 is fixed to each. A set gear 30 and a turning gear 31 are loosely fitted on the transmission shaft 24 at a predetermined interval, and a clutch 32 is slidably fitted in between. 33 is a gear that meshes with the planting gear 30, 34 is a gear that meshes with the turning gear 31, 35 is a running launch, and 36 is a gear fitted to the axle 5.

A planting clutch 37 is provided on the speed change shaft 24. 38 is a gear loosely fitted on the speed change shaft 24, 39 is a gear meshing with the gear 38, 4o is its shaft, 41 is a bevel carrier, 42 is a hepel carrier 43 is an intermediate shaft, and 44 is a lead cam shaft.

The control handle 1O is provided with a lever 45, like a bicycle brake handle, which can be operated while holding the control handle 1O. 46 is a wire connected at one end to the lever 45, and an arm 48 is attached to the other end of the wire via a spring 47. 49 is a return spring. The arm 48 is pivotally attached to a shaft 50, and a shifter 51 is removed. The shifter 51 is configured to
2 is engaged. The clutch 32 and the planting gear 30
The meshing between the clutch 32 and the turning gear 31 is as shown in FIG. 6, and the meshing between the clutch 32 and the turning gear 31 is as shown in FIG.

Next, I will explain the effect.

Start the engine 2, enter the field, squeeze the latch 35, engage the latch 35 to engage the gear 36, and the ash/<,? , 49 causes the shifter 51 to rotate clockwise in FIG. 3, so the clutch 32 meshes with the small teeth 30.

Also, planting kura.

The wire 52 leading to the lunch 37 becomes loose and becomes narrower than the lunch 37.
fits with the tooth 1138 by the spring 53 (i).

Therefore, output shaft 22 → gear 26 → gear 27 → gear 28 → tooth 1!2
9 -> transmission shaft 24 -> clutch 32 - planting gear 30 -> gear 33 -> running latch 35 -> gear 36 -> axle 5 -> wheel 6 The one-wheeled rice transplanter moves forward at the speed of planting. On the other hand, gear shift IklI24 → planting clutch 37 → gear 38 → tooth d
The rotation is transmitted as follows: <39→shaft 40→bevel carrier 41→bevel carrier 42→intermediate shaft 43, and the planting device 7 and lead cam shaft 44 rotate to move the bacteria tank 8. When reaching the end point, he grips the control handle 10 and the lever 45, and the wire 46 → spring 47 → arm 48 → shift lever 51 →
The clutch 32 is disengaged from the planting gear 30 and meshes with the turning gear 31. Therefore, the turning gear 31
→ Gear 34 → Running latch shaft 25 → Running latch 35 →
Rotation is transmitted from gear 36 to axle 5 to wheel 6, resulting in a slow turning speed. Also,
The planting crane 37 is moved using the wire 52 to plant 1.
・Separate the j flange 3f and gear 38, and close the planting part.

As already mentioned, conventionally known rice transplanting devices include four-wheel riding type, two-wheel walking type, -wheel walking type, and other types. When turning fsIj, this phenomenon almost never occurs, or in the wheel-sailing type, because of the wheel, if you don't hold the handle firmly with both hands, you may be able to turn it over to the left or right. In particular, when planting without moving forward, even if you use one hand, it will be relatively stable and will not fall over, and when you reach the end point or turn, you will inevitably tilt the aircraft. 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 transplanting device is that when it is moving straight, it moves forward at a speed that is easy to walk.

When making a U-turn, it would be good if the speed was automatically reduced to a speed that makes it easier to turn.

However, the present invention provides an assault-type one-wheel rice transplanting device having one wheel, in which a walking control handle of the rice transplanting device is provided with an operating lever that can be operated while holding the handle,
A one-wheel rice transplanter in which the operating lever and a transmission are linked, and the rice transplanter is provided with a transmission that can switch between planting speed and turning speed, and a walking control handle of the rice transplanter is provided with a transmission. is a one-wheel rice transplanter 6 which is provided with an operating lever that can be operated while holding the handle, and which is connected to the transmission X1; A single-wheel type rice transplanter with a formula structure, a single-wheel type 11 rice transplanter with a control lever that will go to planting speed (=J speed) if it is not operated, or a turning speed if it is operated, and a +ii J rice transplanter. The planting clutch shown in Fig. 1 is also similar to the one-wheel type 11-planting device that is linked to the operating lever, so the operator enters the field, squeezes the lever 45, and engages the running clutch 35 with the gear 36. When the clutch 32 engages with the planting gear 30 due to the elasticity of the nozzle spring 49, the wire 52 leading to the planting clutch 37 becomes loose, and the planting clutch 3
7 is engaged with the gear 38 by the spring 53, and the -wheel type rice transplanting device moves forward at the planting speed. After reaching the end point and gripping the control handle 10, when the lever 45 is squeezed, the clutch 32 disengages from the planting gear 30 and engages with the turning gear 31.
This results in a slow turning speed.
