Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a two-wheeled riding reaper.

The leading end of a sled-shaped support frame at the rear end is pivoted to an appropriate location on the body of a reaper that has a pair of running wheels, and the sled-shaped support frame is moved from the body of the machine to the rear of the running wheels. If the support frame is extended and a seat is provided above the rear end of the support frame, the two-wheeled reaper can be turned into a riding-type reaper that can be operated by riding on the seat. This configuration allows riding-on reapers to be provided at low cost due to its extremely simple structure; however, riding-on reapers with this configuration still have the following problems and inconveniences. It was hot.

In other words, with the sled-shaped support frame as described above, there is no problem even if you ride on the seat above it and drive the reaper straight, and the support frame can slide smoothly on the field. When turning the reaper, the sled-shaped support frame does not easily slide in the lateral direction, so it is impossible to turn the reaper while riding on it. Therefore, when turning a riding reaper with such a structure, the operator had no choice but to get off the seat and turn the reaper each time. By making use of the advantages of the riding reaper, that is, by maintaining the above-mentioned simple configuration for riding, and by adding some improvements to it, the operator does not have to leave the seat even when turning. No need to get off
In other words, the aim is to provide a two-wheeled riding reaper that can be easily turned around even when the operator remains on the machine. The tip of a support frame with a seat at the rear thereof is pivoted to a suitable position on the body of a two-wheeled reaper equipped with a seat via the axis of the running wheel or a fulcrum shaft parallel to the axis of the running wheel, An auxiliary wheel frame having an auxiliary wheel and a pedal positioned at the rear and supported on the auxiliary wheel via an axle perpendicular to the axis of the running wheel is provided, and the auxiliary wheel frame is positioned at the rear of the running wheel. This two-wheeled riding reaper is characterized in that it is supported by a machine body so as to be able to move up and down at any position.

To explain the embodiment with reference to the figures, this embodiment relates to a two-wheel type one-row cutting and binding machine, and 1 is:
A reaping section provided on the front side of a main body 4 having running wheels 2 and a driving section 3 thereof, and similar to the conventional device, this reaping section 1 has a divider 5 for separating planted grain culms.
, a pulling device 6 that pulls up the planted grain culms separated by the divider 5, a cutting blade device 7 that reaps the pulled grain culms, and a binding machine 8 that binds the harvested grain culms. This reaping and tying machine consists of a support frame 11 whose tip end portion 11a is pivotally supported by the axle 10 of the pair of running wheels 2, and whose rear side is warped, which swings relative to the main body. The seat 12 is provided on the rear end of the support frame 11, and the seat 12 is configured to be a riding type.
This reaping and binding machine includes an axle 10 of the traveling wheels 2.
The following auxiliary wheel frame 13 is attached to support the wheel.

That is, this reaping and binding machine has the axle 10.
Like the support frame 11, a fork-shaped auxiliary wheel frame 13 is attached at the rear of the main body 4 so as to be able to swing vertically, with its bifurcated tip 13a pivotably supported. An axle 14 orthogonal to the axle 10 of the traveling wheel 2 is provided at a suitable location on the free end side of the wheel frame 13, and an auxiliary wheel 15 is rotatably attached thereto. , a plate-shaped pedal 16 is attached to the auxiliary wheel frame 13, and even with a tension spring 17 stretched between the proper position of the auxiliary wheel frame 13 and the main frame 4, the auxiliary wheel 15 is always slightly raised above the field surface. It is designed to be suspended in a ivy position. In addition, 1
Reference numeral 8 denotes an operating handle of the reaping and tying machine that projects from the main body 4.

Since the two-wheeled riding reaper of the present invention is constructed as described above, it can be steered as follows. That is, the seat 12, which is provided so that the worker can ride on it, has its tip end pivoted to a suitable position on the machine body via the shaft 10 of a pair of running wheels or a support shaft parallel to the shaft 10. , support frame 11
Since the seat 12 is provided at the rear, which is the free end side, even if an operator rides on this seat 12, when the reaper moves straight, the support frame 11 on which the seat 12 is provided will not be able to reach the rear end. Because it comes into contact with the rice paddy surface and slides on the rice paddy surface, even if a worker is sitting on the seat 12,
The work can be carried out smoothly without any hindrance,
When turning, the operator can turn the machine without getting off the reaper by doing the following.

That is, when the reaper reaches the turning position, the operator must temporarily stop the machine, stand up from the seat holding the handle 18, and shift his/her weight from the seat to the back of the auxiliary wheel frame 13. If you move it to the pedal 16 at the end, the auxiliary wheel 15 will be
7 and comes into contact with the rice field (dashed line in Figure 1), and the support frame 11 is able to weaken its ground pressure against the rice field. If the wheels 2 are driven again and the turning operation is performed, the machine will not be hindered by the resistance of the support frame 11 against the rice field, and the left and right traveling wheels 2 will move even when the operator remains on the machine.
This makes it possible to smoothly turn one of the two points approximately as the turning center. Note that if the ground contact portion at the rear end of the support frame 11 is configured to have a curved shape 11b in the lateral direction as shown in FIG. make the resistance smaller,
Needless to say, it is possible to turn the reaper more smoothly. In another embodiment, a tension spring is provided between the support frame and the main body, so that when the worker shifts his/her weight from the support frame to the auxiliary wheels during turning, the support frame is slightly tilted to the surface. It may be configured so that it floats upward.

Since the two-wheeled reaping machine according to the present invention is constructed and operates as described above, there is no inconvenience during turning as described at the beginning, and the two-wheeled reaping machine according to the present invention can be easily used during the entire reaping process including straight reaping and turning. This can be done while remaining on the aircraft, and its structure is extremely simple and convenient.

In the above-mentioned embodiment, the tip 13a of the auxiliary wheel frame 13 is pivotally supported on the axle 10 of the running wheel 2, but in other embodiments, the tip of the auxiliary wheel frame 13 is The wheels 2 may be pivotally supported at a suitable location on the fuselage other than the axle 10, for example, on the frame of the main body.In still other embodiments, the auxiliary wheel frame 13 may not be pivotally supported on the fuselage, but by an appropriate link device. Alternatively, the auxiliary wheels may be supported by the vehicle body via, etc., and the auxiliary wheels may be configured to be movable up and down at a position behind the traveling wheels. In addition, in the above embodiment, an example was shown in which the pedal was formed by a plate fixed to the auxiliary wheel frame 13, but in other embodiments, the pedal is a part of the frame member constituting the auxiliary wheel frame 13. It may also be the department itself.
