[0001]

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

[0002]

2. Description of the Related Art As a fertilizer application apparatus as described above, a fertilizer storage hopper, a feeder for feeding fertilizer from a fertilizer storage hopper, a feeder for feeding fertilizer to a field, and a guide for guiding the fertilizer fed from the feeder to a feeder. Some are provided with pipes, and there are many rice transplanters with fertilizers that fix the fertilizers at predetermined positions.

[0003]

In the fertilizer of a rice transplanter with a fertilizer as described above, since other devices are often arranged near the fertilizer storage hopper and the feeding part, the fertilizer storage hopper and In some cases, it is difficult to perform maintenance work on the feeding portion and other devices nearby.
An object of the present invention is to make it easier to perform maintenance work on a fertilizer storage hopper and a feeding portion of a fertilizer applicator and other devices near the fertilizer applicator in a rice transplanter with a fertilizer applicator.

[0004]

A feature of the present invention is that a rice transplanter with a fertilizer is configured as follows. A fertilizer storage hopper, a feeder that feeds fertilizer from the fertilizer storage hopper, a feeder that feeds the fertilizer to the field, and a guide pipe that guides the fertilizer that is fed from the feeder to the feeder, with the planting of the seedlings A fertilizer that feeds fertilizer into the field is constructed, and the discharge port of the feeding section is formed in a trumpet shape that spreads downward, so that the discharge port can be freely connected and separated so as to cover the inlet end of the guide pipe from above. Work where the discharge port is connected to the inlet end of the guide pipe by setting the inner diameter of the inlet end of the guide pipe to be larger than the inner diameter of the upper part of the discharge outlet, and connecting the fertilizer storage hopper and the feed section to the inlet end of the guide pipe. It is movably supported while maintaining the posture at the work position over the position and a non-work position away from the work position.

[0005]

According to the first aspect of the present invention, in the fertilizer application apparatus, the fertilizer storage hopper and the feeding section located at the work position can be moved to the non-work position away from the work position. Thereby, by separating the fertilizer storage hopper and the feeding part from the working position to the non-working position, the maintenance work of the fertilizer storage hopper and the feeding part can be performed without being disturbed by other devices arranged near the working position. It can be done easily. Maintenance work of other devices arranged near the work position can also be easily performed without being obstructed by the fertilizer storage hopper and the feeding section.

When moving the fertilizer storage hopper and the feeding section between the working position and the non-working position, the fertilizer storage hopper and the feeding section can be moved while maintaining the posture at the working position. When moving the fertilizer storage hopper and the feeding section, the fertilizer in the fertilizer storage hopper and the feeding section does not spill out, and there is no need to take out the fertilizer from the fertilizer storage hopper and the feeding section for the moving operation.

[II] In a fertilizer applicator comprising a fertilizer storage hopper, a feeder, a guide pipe, and a feeder, a feeder for feeding fertilizer into a field is disposed relatively low near the field, and the fertilizer storage hopper is provided. The guide pipe is formed relatively long so as to connect the feeding section and the feeding section. Therefore, if such a feeding part and a guide pipe are configured to be movable to a non-working position together with the fertilizer storage hopper and the feeding part, the moving structure of the fertilizer apparatus becomes large. According to the feature of the first aspect, the feeding part and the guide pipe are left at the working position side, and the fertilizer storage hopper and the feeding part are configured to be movable from the working position to the non-working position. Is not a big deal.

[III] According to the feature of claim 1, when the fertilizer storage hopper and the feeding part are moved to the working position side to connect the discharge port to the inlet end of the guide pipe, the position of the discharge port and the position of the discharge port are determined. Even if the position of the inlet end of the guide pipe is slightly deviated, the inlet end of the guide pipe is guided by the spout which spreads like a trumpet, and the outlet and the inlet end of the guide pipe are accurately connected. .

[0009] At the working position of the fertilizer storage hopper and the dispensing section, the discharge end of which is connected to the entrance end of the guide pipe, the entrance end of the guide pipe is covered from above by a trumpet-shaped discharge opening that spreads downward. Since the discharge port and the inlet end of the guide pipe are engaged with each other, the discharge port and the inlet end of the guide pipe are connected without disconnecting at the working positions of the fertilizer storage hopper and the feeding section. To maintain. This eliminates the need for a special connecting member or the like for maintaining the connection between the discharge port and the inlet end of the guide pipe. In the working position of the fertilizer storage hopper and the feeding section, a trumpet-shaped discharge port that spreads downward is located above the entrance end of the guide pipe, so that rainwater does not enter the guide pipe. .

[IV] If the inner diameter of the inlet end of the guide pipe is not larger than the inner diameter of the upper part of the outlet, fertilizer from the outlet may ride on the surface of the inlet end of the guide pipe. When the fertilizer storage hopper and the feeding part are moved to the non-working position, the fertilizer on the surface of the inlet end of the guide pipe spills out and adheres to the metal part, causing rust and the like. Sometimes. According to the feature of claim 1, since the inner diameter of the inlet end of the guide pipe is set to be larger than the inner diameter of the upper part of the discharge port, the fertilizer from the discharge port is in the working position of the fertilizer storage hopper and the feeding section. It is fed into the guide pipe without spilling, so that the fertilizer does not ride on the surface of the entrance end of the guide pipe.

[0011]

According to the first aspect of the present invention, in the rice transplanter with the fertilizer application device, the fertilizer storage hopper and the feeding portion located at the working position can be moved to the non-working position remote from the working position. The maintenance work of the fertilizer storage hopper and the feeding section and other devices arranged near the work position can be easily performed, and the workability of the rice transplanter with the fertilizer application device can be improved. Was.

When the fertilizer storage hopper and the feeder are moved between the working position and the non-working position, the fertilizer in the fertilizer storage hopper and the feeder does not spill out. There is no need to remove the fertilizer from the hopper and the feeding section, and no waste of the fertilizer is required, and the occurrence of rust or the like due to the fallen fertilizer adhering to the metal part is prevented.

What is necessary is to move the fertilizer storage hopper and the feed-out portion from the working position to the non-working position while leaving the feeding portion and the guide pipe on the working position side, so that the moving structure of the fertilizer is large. In particular, there is no need for a special connecting member to maintain the connection between the discharge port and the inlet end of the guide pipe at the working position of the fertilizer storage hopper and the feeding section. It is advantageous in terms of aspect.

[0014] When the fertilizer storage hopper and the feeding section are moved to the working position to connect the discharge port to the inlet end of the guide pipe, the inlet end of the guide pipe is guided by the discharge port expanding in a trumpet shape. Since the discharge port is connected to the discharge port, the connection between the discharge port and the entrance end of the guide pipe can be easily performed, and the operability is improved. At the working position of the fertilizer storage hopper and the feeding part, rainwater etc. do not enter the guide pipe due to the trumpet-shaped discharge port, so that fertilizer adheres to the guide pipe due to rainwater etc. The clogging phenomenon is prevented beforehand.

By setting the inner diameter of the inlet end of the guide pipe larger than the inner diameter of the upper part of the outlet, the fertilizer from the outlet is fed into the guide pipe without spilling, and the surface of the inlet end of the guide pipe is provided. As a result, the occurrence of rust and the like due to the fall of the fertilizer is further prevented.
