Description

[Detailed description of the invention] This invention relates to a simple riding rice transplanter, which has a driver's seat supported by wheels so that it can move freely, which is detachably connected to the rear part of the walking rice transplanter through an appropriate connection mechanism. be.

A walking rice transplanter has a machine body supported by one or two drive wheels so as to be able to move up and down, and when running, the rear part of the machine tends to sink due to the reaction force of the drive wheels. However, since the operator operates the machine while moving, the machine can be driven horizontally by lifting and supporting the handle protruding from the rear of the machine.

However, in the conventional simple riding rice transplanter, the driver's seat, which is supported by wheels so that it can move freely, is connected to the rear of the body of the walking rice transplanter through an appropriate connection mechanism so that it can move left and right and up and down. The reaction force caused the rear of the aircraft to sink, causing the cockpit to tilt forward. Moreover, in order to maintain the aircraft horizontally,
As with the walking rice transplanter, it required a great deal of effort for the operator in the cockpit for the operator to slightly lift the handle and support it, and it was extremely difficult to move the machine horizontally.

The present invention aims to eliminate the above-mentioned drawbacks, and provides a simple riding rice transplanter that can stably run horizontally without causing the rear part of the machine to sink.

Another object of the present invention is to provide a simple riding rice transplanter that can be adjusted at any time by operating a foot pedal to move the machine horizontally in accordance with the depth of the tiller. It is.

That is, this idea provides a connecting device at the rear of the fuselage that can be rotated left and right, a connecting rod that can be moved vertically and vertically, and a cockpit that is movably supported by wheels at the rear end of the connecting rod. A foot pedal is pivotally supported on the connecting rod so as to be freely rotatable back and forth, and a latch claw that swings in conjunction with the foot pedal is provided, and the latch claw is provided on the connecting tool. The gist of this invention is the structure of a simple riding rice transplanter characterized by being able to be freely latched onto a latching tool.

Next, this invention will be explained according to the illustrated embodiment. 1 is the body of a walking rice transplanter. The body 1 is supported by driving wheels 2 so as to be freely movable, and a handle 3 is provided protruding from the rear. Reference numeral 4 denotes a connector, which is provided at the rear of the fuselage 1 via a pivot 5 so as to be rotatable left and right. Reference numeral 6 denotes a continuous rod, which is supported so as to project rearward via a connecting shaft 7 so as to be movable up and down relative to the connecting tool 4. 8 is a hanging tool, and the connecting tool 4
A large number of tooth-shaped grooves 9, 9... are arranged in a fan shape on the rear edge.

Reference numeral 10 denotes a pilot's seat, which is movably supported by wheels 11 and is connected and supported to the rear end of the connecting rod 6 so as to face the control device at the rear of the fuselage 1.

Reference numeral 12 denotes a foot pedal, which is pivotally supported to the connecting rod 6 via a receiving plate 13 vertically provided on the connecting rod 6 so as to be rotatable back and forth. This foot pedal 12 is biased by a spring 14, and has a latch claw 15 protruding laterally at its lower end. This latch claw 15 is loosely fitted into a long hole 16 bored in the receiving plate 13, and its tip is hooked by a spring 14 into an arbitrary tooth-shaped groove 9 provided in a latch 8 at the rear end of the connector 4. It is biased so that it can be stopped at will. When the latching pawl 15 is latched into the tooth-shaped groove 9 of the latching device 8, the connecting rod 6 is fixed to the connecting device 4 and cannot be rotated. This latch claw 15 is activated by pressing the foot pedal 12 to release the spring 1.
The latch 8 moves back very easily against the bias of the hook 8.
is released from the toothed groove 9, and the connecting rod 6 becomes able to move up and down relative to the connector 4.

This idea is structured as above, so
Even when an operator sits on the cockpit 10 and moves the machine 1, the connecting tool 4 and the connecting rod 6 are integrally fixed by the latching pawl 15 on the latching tool 8, and the drive wheel 2
The reaction force is absorbed by the wheels 11 supporting the cockpit 10, and the aircraft 1 runs stably horizontally without sinking the rear part.

However, when the plowing depth changes, the machine body 1 will tilt either forward or backward. Then, the foot pedal 12 is depressed, and the latching pawl 15 on the latching tool 8 is pressed down.
When the handle 3 is released and the handle 3 is moved up and down as appropriate, the body 1 returns to the horizontal state very easily.
When the foot pedal 12 is released when the aircraft 1 is horizontal, the latch claw 15 is released from the spring 14.
Due to the biasing force, the machine body 1 is latched to the appropriate tooth-shaped groove 9 of the latching member 8, and the body 1 continues to run horizontally.

As described above, according to the present invention, the operator has the practical benefit of being able to move the aircraft horizontally while remaining in the cockpit without operating the steering wheel.

In addition, when using the present invention, the vertical movement of the connecting rod supporting the cockpit seat at the rear of the aircraft can be easily locked and unlatched using the foot pedal, so only a slight steering wheel operation is required. This has the practical advantage of being able to arbitrarily adjust the machine body so that it travels horizontally in accordance with the depth of the plowing platform.
