[I] According to the feature of the first aspect, the fertilizer storage hopper and the feeding portion located at the work position in the fertilizer application apparatus can be moved to the non-work position, which is separated upward from the work position.
By moving the fertilizer storage hopper and the feeding section to the non-working position away from the working position in this way,
The maintenance work of the fertilizer storage hopper and the feeding section can be easily performed without being disturbed by other devices and structures arranged near the work position.

According to the first aspect of the present invention, since the fertilizer storage hopper and the feeding section can be moved up and down between the working position and the non-working position separated upward, the moving operation to the non-working position separated upward can be performed. Therefore, the fertilizer storage hopper and the feeding portion do not largely extend laterally from the range of the rice transplanter with the fertilizer application device.

According to the first aspect of the present invention, when the fertilizer storage hopper and the feeding section are moved between the work position and the non-work position separated upward, the fertilizer storage hopper is maintained in a posture in the work position. And the feeding part can be moved, so that when the fertilizer storage hopper and the feeding part are moved, the fertilizer is less likely to spill from the fertilizer storage hopper and the feeding part, and the fertilizer storage hopper is used for the moving operation. There is also little need to remove fertilizer from the feeding section.

And the guide path is relatively long so as to connect the feed section and the feed section. Therefore, if such a feeding part and a guide path are configured to be freely 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 first aspect of the present invention, a separating section is provided at an intermediate portion of the guide route, and the fertilizer storage hopper and the feeding section are operated by leaving the feeding section and the section on the feeding side from the separating section in the guide path. Since it is configured so as to be movable to a non-working position that is separated from the position upward, the moving structure of the fertilizer application device (fertilizer storage hopper and feeding unit) does not become large.

[III] According to the feature of the first aspect, the separation portion in the middle of the guide route according to the above item [II] is an outlet on the upper side (extending portion side) and an entrance on the lower side (feeding portion side). And a cover member provided on the outlet side (feeding part side) and covering the outside of the outlet from above, and at the working position of the fertilizer storage hopper and the feeding part, the outlet and the inlet are formed inside the cover member. Close. As a result, the fertilizer fed from the feeding section is guided without difficulty to the inlet from the portion on the feeding section side and the exit in the guide route, and is guided to the feeding section from the portion on the feeding section side in the guide route and sent into the field.

In this case, a cover member provided on the outlet side (extending portion side) and covering the outside of the outlet from above is provided.
At the working position of the fertilizer storage hopper and the feeding section, the outlet and the inlet are configured to be close to each other inside the cover member, and the portions of the outlet and the inlet that are close to each other are covered from above by the cover member. . Thereby, even if the mud or the like scatters from the field, the cover member prevents the mud or the like from adhering to the portions of the exit and the entrance that are close to each other.

[0012]

According to the first aspect of the present invention, in a rice transplanter equipped with a fertilizer application device, the fertilizer storage hopper and the feeding portion are configured to be movable to a non-working position which is separated from an upper working position to an upper working position. The maintenance work of the hopper and the feeding section can be easily performed, and the workability of the rice transplanter with the fertilizer device can be improved.

According to the first aspect of the present invention, the fertilizer storage hopper and the feeding portion can be moved to the non-working position, which is separated upward without any trouble, without having to be extended largely in the lateral direction. Workability was improved. According to the feature of claim 1, when the fertilizer storage hopper and the feeding part are moved between the working position and the non-working position separated upward, the fertilizer may fall out from the fertilizer storage hopper and the feeding part. Because there are few,
There is no need to take out the fertilizer from the fertilizer storage hopper and the feeding section for the moving operation, and there is no waste of fertilizer, and the generation of rust due to the fallen fertilizer adhering to the metal part is also prevented. .

According to the first aspect of the present invention, the separation part is provided in the middle part of the guide route, so that the fertilizer storage hopper and the feeding part can be operated while leaving the feeding part and the part on the feed side from the separation part in the guide path. The movable structure of the fertilizer (fertilizer storage hopper and feeding part) does not become large-scale because it is configured to be movable to the non-working position, which is separated from the position above, which is advantageous in terms of simplification of the structure. became.

According to the first aspect of the present invention, at the working position of the fertilizer storage hopper and the feeding section, the portions of the outlet and the inlet which are close to each other are covered from above by the cover member, so that mud and the like scattered from the field are removed from the outlet and the inlet. Can be prevented from adhering to the mutually adjacent parts of the fertilizer, so that mud adheres to the mutually adjacent parts of the outlet and the entrance and enters the inside of the guide path, causing clogging of fertilizer. Could be prevented.
