DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice transplanter having a fertilizer application device in which a fertilizer application device is disposed above a seedling planting mechanism of the seedling transplantation device.

[0002]

2. Description of the Related Art An example of a rice transplanter with a fertilizer device as described above is disclosed in Japanese Utility Model Laid-Open No. 1-155715. In this rice transplanter with a fertilizer application device, a mud avoiding cover is provided above the seedling planting mechanism in order to prevent the mud in the field from being jumped up by the fertilizer device above the seedling planting operation of the seedling planting mechanism. Has been arranged. In this case, the support member of the mud avoiding cover is provided on the transmission case side supporting the seedling planting mechanism, and the mud avoiding cover is supported from below by this supporting member.

[0003]

As described above, when the mud avoiding cover is supported by the transmission case via the support member, when the seedling planting mechanism jumps up the mud, the mud is not limited to the mud avoiding cover. Instead, it also adheres to the support member. Therefore, when cleaning is performed by removing the mud avoiding cover, it is necessary to remove not only the mud avoiding cover but also the mud of the supporting member, and the removing of the mud of the supporting member has a relatively complicated shape. It is hard to do because of An object of the present invention is to provide a rice transplanter equipped with a fertilizer with a mud avoiding cover, thereby facilitating removal of mud and simplifying maintenance.

[0004]

In order to achieve the above object, the technical means of the present invention is provided with a feeding portion below the fertilizer storage container, and the fertilizer fed from below the feeding portion is formed into a groove. A seedling provided with a fertilizer and a seedling planting mechanism provided with a guide hose for guiding the flow down to the vessel side, and the seedling arranged so that the feeding portion and the fertilizer storage container are located above the seedling planting mechanism. In a rice transplanter equipped with a fertilizer applicator equipped with a planting device, a feeding part of the fertilizer device supports a fertilizer storage part capable of receiving fertilizer flowing down, and a lower part of the fertilizer storage part, above the seedling planting mechanism. Is to support a mud avoiding cover for preventing mud from jumping up.

[0005]

According to the structure of the present invention, the mud avoiding cover disposed above the seedling planting mechanism is not provided in the transmission case of the seedling planting mechanism as in the conventional structure, but in the upper side of the seedling planting mechanism. No support member is needed to support the mud avoiding cover with respect to the transmission case of the seedling planting mechanism as in the conventional configuration, since it will be supported via the fertilizer storage unit at the feeding section of the fertilizer application device located at Become.

[0006] Therefore, as the seedling planting mechanism jumps up the mud, the splashed mud adheres to the downward mud avoiding surface of the mud avoiding cover for suppressing the scattering of the mud to the fertilizer application side. On the other hand, since the part supporting the mud avoiding cover with respect to the fertilizer applicator is located above the mud avoiding cover, the mud adhering to this part also causes the mud scattering to the fertilizer applying apparatus side. To prevent mud avoiding cover by preventing.

[0007] Further, since the mud avoiding cover is supported on the fertilizer application side, the feeding section and the fertilizer storing section can be provided as close as possible to the mud avoiding cover. Therefore, it is expected that an effective mud avoidance effect for the fertilizer storage unit and the feed-out part can be expected while using a relatively small-area and small-sized cover as a mud-repellent cover for the fertilizer storage part and the feed-out part where it is desired to avoid adhesion of mud. it can.

When the fertilizer storage section is made transparent and used as a powder recovery section, adhesion of mud to the transparent portion can be avoided, so that the visual confirmation of the stored amount is not hindered by the adhered mud.

[0009]

As described above, in the rice transplanter with the fertilizer application device, the fertilizer storage portion, which may be an existing fertilizer storage device, is also used as a support member for the mud avoidance cover, and the fertilizer application device supports the mud avoidance cover. The support member of the avoiding cover can be omitted, and the structure can be simplified by reducing the number of parts. Then, the presence of the mud avoiding cover prevents the mud from adhering to the fertilizer storage unit, and the support means of the mud avoiding cover does not exist below the mud avoiding cover. Therefore, during maintenance, cleaning of the fertilizer storage section is not necessary, and since there is no support member, cleaning is not necessary, just cleaning the mud of the mud avoiding cover itself is necessary for maintenance. Cleaning can be completed, and there is a practical advantage that the cleaning is simplified. In addition, since the mud avoiding cover is supported by the fertilizer application device, and the feeding section and the fertilizer storage section can be provided as close to the mud avoiding cover as possible, a relatively small area and compact With the use of the cover, it is possible to reliably prevent the mud from scattering to the fertilizer storage section and the feeding section where it is desired to avoid adhesion of mud. Further, when the fertilizer storage unit is used as a powder recovery unit by making it transparent, it is possible to avoid the adhesion of mud to the transparent part, so that it is not necessary to interrupt the planting operation frequently to confirm the amount of stored powder. The stored amount can be easily confirmed by visual observation from the user, which is effective in improving workability.
