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]

[1]

A guide member arranged vertically and a support member having a pair of upper and lower guide rollers are provided, and the support member is movably supported by the guide rollers along the guide member. The fertilizer device that feeds the fertilizer into the plurality of strips is connected to and supported by the support member, and the fertilizer device is moved from a lower working position for feeding the fertilizer to the field and a non-working position that is separated upward from the working position. It is movably supported while maintaining the posture at the position. [2] In the configuration of the above item [1], an urging mechanism for lifting and urging the fertilizer applying device to the non-working position side is connected to the support member.

[0005]

According to the first aspect of the present invention, the fertilizer applicator located at the work position can be moved to the non-work position away from the work position via the support member (guide roller) and the guide member. Thereby, by separating the fertilizer application device from the work position to the non-work position, maintenance work of the fertilizer device can be easily performed without being disturbed by other devices arranged near the work position. Maintenance work of other devices arranged near the work position can also be easily performed without disturbing the fertilizer application device.

When the fertilizer is moved between the working position and the non-working position, the fertilizer is moved via a supporting member (guide roller) and a guide member while maintaining the posture at the working position. Therefore, when the fertilizer is moved, the fertilizer in the fertilizer does not fall out, and there is no need to take out the fertilizer from the fertilizer for the moving operation.

According to the second aspect of the present invention, the fertilizer can be moved up and down between the lower working position and the upper non-working position. The fertilizer does not protrude largely in the lateral direction from the rice transplanter. Accordingly, even in a relatively narrow place such as a barn, the fertilizer application device can be moved to the upper non-working position without any trouble.

When the fertilizer application device is vertically moved along the guide member by the support member, a pair of upper and lower guide rollers provided on the support member are moved in the moving direction of the support member (up and down direction along the guide member). Since the support member is disposed, the support member does not tilt to the guide member in one or the other direction in the movement direction by the support action of the pair of upper and lower guide rollers during the operation of moving the fertilizer application device along the guide member. . Accordingly, a state in which the support member is tilted to one side and the other side along the movement direction with respect to the guide member, and the movement of the support member along the guide member is not performed smoothly (so-called “coiling phenomenon”). Does not occur.

[III] According to the feature of the second aspect, similar to the case of the first aspect, the "action" described in the above-mentioned [I] and [II] is provided. "Is provided. According to the feature of the second aspect, in addition to the guide member that movably supports the fertilizer device between the working position and the non-work position, the urging mechanism that lifts and biases the fertilizer device to the non-work position is provided. With the assistance of the urging mechanism at the time of the operation for moving to the non-working position, the fertilizer can be easily moved to the non-working position.

In the case where such an urging mechanism is provided, if the urging mechanism is connected to a part of the fertilizer that is separated from the support member (guide roller), the moment generated by the urging force of the urging mechanism becomes large. When the support member is tilted to one side and the other side along the moving direction with respect to the guide member, the koji phenomenon easily occurs. Claim 2
According to the feature of the above, since the urging mechanism is connected to the supporting member, the connection point of the urging mechanism and the guide roller in the supporting member are short, and the moment generated by the urging force of the urging mechanism is small. In other words, the biasing mechanism does not tilt the support member to one side or the other in the direction of movement with respect to the guide member.

[0011]

According to the first aspect of the present invention, in a rice transplanter with a fertilizer device, the fertilizer device can be moved to a non-work position away from the work position, so that the fertilizer device and the fertilizer device are arranged near the work position. The maintenance work of the other apparatus can be easily performed, and the workability of the rice transplanter with the fertilizer application apparatus can be improved. When the fertilizer is moved between the working position and the non-working position, the fertilizer in the fertilizer does not spill out, so there is no need to remove the fertilizer from the fertilizer for the moving operation. There is no waste of fertilizer, and the generation of rust and the like due to the fallen fertilizer adhering to the metal part is also prevented. The fertilizer device can be moved up and down between the lower working position and the upper non-working position so that the fertilizing device can be moved to the non-working position without any trouble even in a relatively narrow place such as a barn. And the workability of the rice transplanter with the fertilizer application device can be further improved. With the pair of upper and lower guide rollers, the fertilizer applicator can be smoothly moved and operated without the occurrence of the koji phenomenon, thereby improving operability.

According to the features of claim 2, the "effect of the invention" of claim 1 is provided as in the case of claim 1. By providing a biasing mechanism for lifting and biasing the fertilizer applicator to the non-working position side, the fertilizer applicator can be easily moved to the non-working position and further operated. It will be good. By connecting the urging mechanism to the support member, the moment generated by the urging mechanism can be reduced, so that the support member is tilted by the urging mechanism to one side and the other with respect to the guide member in the moving direction. This makes it possible to move the fertilizer applicator more smoothly.
