DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice transplanter equipped with a fertilizer, which is provided with a fertilizer for feeding fertilizer to a field as a seedling is planted.

[0002]

2. Description of the Related Art In a rice transplanter with a fertilizer device as described above, a fertilizer device is fixed at a predetermined position, and the predetermined position is set as a work position of a fertilizer device for feeding fertilizer into a field, and fixed at the work position. Many fertilizers are configured to send fertilizer to a field from the fertilizer application devices.

[0003]

In the rice transplanter with a fertilizer device as described above, the fertilizer device is often located near the work position of the fertilizer device. It may be difficult to perform maintenance work on other devices. An object of the present invention is to make it easier for a rice transplanter with a fertilizer to perform maintenance work on a fertilizer and other nearby devices.

[0004]

A feature of the present invention resides in a rice transplanter with a fertilizer application device, which is configured as follows. A fertilizer is provided to feed the fertilizer to the field as the seedlings are planted, and the fertilizer is fed to the field from a working position for feeding the fertilizer to a non-working position that is separated from the working position by a non-working position. In addition to supporting the posture freely while maintaining the posture, the output part is arranged at a position different from the fertilizer at the work position, and the drive rod extends over the input part and the output part of the fertilizer at the work position. And the power of the output unit is transmitted as push-pull power to the input unit via the drive rod, so that one side of the drive rod and the output unit can be connected and disconnected. .

[0005]

[I] According to the features of the first aspect, the fertilizer applicator located at the working position can be moved to the non-working position which is separated upward from the working position. By thus separating the fertilizer application device from the work position to the non-work position, the maintenance work of the fertilizer device can be easily performed without being disturbed by other devices arranged near the work position. Can be. Maintenance work of other devices arranged near the work position can also be easily performed without disturbing the fertilizer application device.

According to the first aspect of the present invention, since the fertilizer can be moved up and down between the working position and the non-working position separated upward, the fertilizer can be moved to the non-working position separated upward. The fertilizer does not protrude largely in the lateral direction from the area of the rice transplanter.

According to the first feature of the present invention, when the fertilizer is moved between the working position and the non-working position separated upward, the fertilizer is moved while maintaining the posture at the working position. Therefore, when the fertilizer is moved, the fertilizer in the hopper of the fertilizer does not fall out, and it is not necessary to take out the fertilizer from the hopper for the moving operation.

[II] When the power of the output unit at a position different from that of the fertilizer is transmitted to the input unit of the fertilizer located at the work position to drive the fertilizer, the above-mentioned [I] When moving the fertilizer applicator to a non-work position, which is separated from the work position upward as described in [1], it is necessary to remove the transmission system from the output section to the input section of the fertilizer apparatus. In this case, if the transmission chain is wound around the output section and the input section of the fertilizer applicator, or if the bevel gear mechanism and the transmission shaft are erected, the transmission chain and the transmission shaft can be removed so that the transmission can be removed. A complicated attachment / detachment structure is required, and this complicated attachment / detachment structure causes an increase in weight.

According to the first aspect of the present invention, a drive rod is connected between the output section and the input section of the fertilizer, and the power of the output section is transmitted to the input section of the fertilizer as push-pull power by the drive rod. And a structure in which the connection between the output unit and the input unit by the drive rod is released by obtaining a configuration in which the connection can be disconnected.

[III] When the connection between the drive rod and the input unit of the fertilizer is released, the connection between the drive rod and the input unit of the fertilizer is released. If the power is erroneously output from the output unit, the long drive rod may be swung while being pushed and pulled, causing damage to the drive rod and the like. is there.

When the connection between one side of the drive rod and the output section is releasable, the connection between the one side of the drive rod and the output section is released.
Even if power is erroneously output from the output unit, the drive rod is separated from the output unit, so that the drive rod is not swung while being pushed and pulled.

[0012]

According to the first aspect of the present invention, in the rice transplanter with the fertilizer applicator, the fertilizer applicator can be moved to the non-working position, which is separated from the work position by an upward movement, so that the fertilizer applicator and the work position are close to each other. The maintenance work of the other devices arranged in the fertilizer application device can be easily performed, and the workability of the rice transplanter with the fertilizer application device can be improved.

According to the first aspect of the present invention, it is possible to move the fertilizer applicator to a non-working position, which is separated upward without any trouble, without extending the fertilizer appreciably in a lateral direction. Could be improved. Claim 1
According to the feature, when the fertilizer is moved between the working position and the non-working position separated upward, the fertilizer in the hopper of the fertilizer does not fall out,
There is no need to remove the fertilizer from the hopper of the fertilizer applicator for the moving operation, and there is no waste of the fertilizer, and the occurrence of rust and the like due to the spilled fertilizer adhering to the metal part is prevented.

According to the first aspect of the present invention, the output unit and the input unit of the fertilizer applicator are connected by a push-pull type drive rod, and the connection can be disconnected. Since the structure for releasing the connection with the input unit can be simplified, it is advantageous in terms of weight reduction. Further, the operation of releasing the connection state and the operation of returning to the connection state can be easily performed, so that the operability is improved. By making the connection between one side of the drive rod and the output part releasable, it is possible to prevent the drive rod from being swung while being pushed and pulled, and to prevent damage to the drive rod and the like. Can be.
