Description

[Detailed Description of the Invention] The present invention relates to a riding rice transplanter in which the rolling of the planting section can be freely stopped in conjunction with the raising and lowering of the planting section.

The planting unit of a rice transplanter, which consists of a planting device and a float, needs to roll freely along the top soil of the field during planting work, but when moving on the road, it must be fixed to the machine and suspended in the air. need to be supported. Conventionally, rolling has been stopped and activated each time by an operator operating an appropriate locking device installed on a support shaft that rotatably supports the planting section relative to the machine body, which is extremely time-consuming. It was troublesome. Particularly with passenger rice transplanters, it is necessary to get out of the cockpit at the rear of the machine and move around to the front to operate the machine, resulting in a decrease in efficiency.

The purpose of the present invention is to eliminate the above-mentioned drawbacks. When the planting part is lowered to the ground, it can roll freely, but when raised, it becomes impossible to roll, and the planting part is fixedly supported on the aircraft body. The present invention provides a riding rice transplanter that can perform

That is, the present invention provides a rice transplanter in which a planting part is rotatably supported via a support shaft at the tip of a lifting arm provided on the machine body so as to be able to rise and fall freely. A connecting rod protruding forward and a locking piece projecting rearward are fixedly provided on the support rod, and the float of the planting portion is rotatably supported in suspension by the connecting rod, and
The gist of the present invention is a structure of a riding rice transplanter characterized in that a lifting arm is provided with a receiver that can be inserted into the tip of a locking piece.

Next, the present invention will be explained according to illustrated embodiments.
1 is the body of a riding rice transplanter. The fuselage 1 is movably supported by front and rear wheels, has a pilot's seat at the rear, and has an elevating arm 2 in the center facing forward of the fuselage 1, which is raised and lowered by a hydraulic mechanism. Reference numeral 3 denotes a support shaft, which is rotatably protruded from the front end of the lifting arm 2 and supports the planting part 5 via a suitable transmission case 4. That is, this planting section 5 consists of a planting device 6 and a float 7, and can be raised and lowered with respect to the aircraft body, and can be rotated left and right (rolling).
It is free. Reference numeral 8 denotes a bearing arm, which is suspended from the mission case 4 supported at the tip of the support shaft 3, and a support rod 9 is rotatably mounted on the lower end of the transmission case 4.
This support rod 9 includes a connecting rod 10 that projects forward,
A locking piece 11 protruding rearward is fixedly provided, and the above-mentioned float 7 is rotatably suspended and supported at the tip of the connecting rod 10 by a fitting 12 provided protruding from its upper surface. Further, the locking piece 11 protrudes below the lifting arm 2 and moves up and down in the opposite direction to the connecting rod 10 as the support rod 9 rotates.

Reference numeral 13 denotes a receiver, which is provided at the lower part of the lifting arm 2 so that the locking piece 11 rotated upward can be inserted freely.
A guide groove 14 with an enlarged lower part is bored.

Since the present invention is configured as described above, when planting, first place the machine body 1 into the field and lower the lifting arm 2, the planting section 5 grounds the float 7 and connects it to the machine body 1 via the wire. It is suspended and supported by an automatic swing device 15 provided therein. At this time, the float 7 is pushed up by the resistance of the field topsoil to rotate the connecting rod 10 upward, so the locking piece 11 rotates downward and deviates outward from the guide groove 14 of the receiver 13.
The rotating shaft 3 is rotatable, and the planting section 5 can be planted while rolling. Next, when traveling on the road, etc., first stop planting and raise the lifting arm 2. The planting part 5 will be supported in the air, and the float 7 will be moved by its own weight to the connecting rod 1.
Since it acts to rotate the locking piece 1 downward, the locking piece 1
1 rotates upward and is fitted into the guide groove 14 of the receiver 13 to prevent its rotation, and the planting part 5 is fixedly supported at the tip of the lifting arm 2, allowing the machine 1 to travel safely.

As described above, the present invention has the practical benefit of being able to extremely easily stop and start rolling of the planting section in conjunction with the raising and lowering of the planting section.
