Description

The present invention relates to a riding rice transplanter equipped with a herbicide spraying device.

[Conventional technology]

As the rice transplanter described above, for example, as disclosed in Japanese Utility Model Application Laid-Open No. 63-191112, a configuration is known in which a herbicide is sprayed over the entire planting width behind a seedling planting device.

The herbicide dissolves and diffuses in the form of a film on the rice field, thereby inhibiting the growth of weed seeds that have come to the rice field and exerting its effect. is there.

Therefore, in the above-mentioned known example, a means for removing the herbicide attached to the planted seedlings with a brush-like wiping tool is added.

[Problems to be solved by the invention]

The above conventional means is effective when the planted seedlings are firmly planted in the field, but when the rice field is particularly soft, there is a problem that the posture of the planted seedlings is deteriorated due to contact with the wiping tool. There were restrictions on the conditions that could be used.

The present invention has been made in view of such a point, and an object of the present invention is to make it possible to suppress direct sprinkling of a herbicide on a planted seedling under any field conditions.

[Means for solving the problem]

A characteristic configuration of the present invention is that, in a conventional rice transplanter provided with a herbicide spraying device for spraying a herbicide behind a seedling planting device provided in a rear portion of a regular traveling vehicle body, the herbicide to be sprayed adheres to a planted seedling. And a linking means for switching the guide member between an anti-adhesion operating state and a non-operation state in which the anti-adhesion effect is not exhibited in synchronization with the seedling planting mechanism.

(Operation)

According to the above configuration, the seedlings are planted and the herbicide is sprayed to the planting locations throughout the planting run, but the guide member guides the sprayed herbicides so that they do not fall directly on the planted seedlings.

In addition, by operating the guide member in synchronization with the seedling planting mechanism, in a place where the planted seedling is present, the guide member is in an adhesion preventing operation state in which the herbicide is guided so that the herbicide does not fall directly onto the planted seedling. The guide member is switched to the non-operating state in the location where no is present, and the herbicide is sprayed on the rice field avoiding the location where the planted seedling is present.

In other words, by operating the guide member in synchronization with the seedling planting mechanism and spraying while preventing the herbicide from falling onto each planted seedling, the non-spreading area for avoiding the location of each planted seedling is set. Instead of forming a long continuous line along the row, the spotted seedling can be formed only around the location where the seedling exists for each seedling plant. As a result, the non-spreading area can be sprayed so as to form only the small area including each planted seedling existing location. The agent can be sprayed.

〔The invention's effect〕

 The effects based on the above configuration are as follows.

That is, by spraying while preventing the herbicide from falling onto each planted seedling, there is no need to apply any external force to the planted seedling to shake off the herbicide. Therefore, the posture of the seedling immediately after planting is not degraded by the external force for shaking off the herbicide, and the occurrence of chemical damage such as the occurrence of seedling death due to the attachment of a large amount of the herbicide to the planted seedling can be avoided.

Then, in synchronization with seedling planting, by spraying while preventing the herbicide from falling onto each planted seedling, the non-spraying area to avoid the location of each planted seedling is included, including the seedling existing location of the planted seedling. However, it is possible to spray the herbicide in a small area as much as possible without waste and easily exhibit the herbicidal effect effectively.

Therefore, it was possible to satisfactorily perform both seedling planting and herbicide spraying.

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

A pair of claw cases (11) each having a planting claw (10) at both ends of a rotating case (9) that rotates forward at a constant speed about the axis (P) is mounted so as to be capable of changing the posture. The planting is performed twice by one rotation of the rotating case (9). ing.

The fertilizer device (12) and the herbicide spraying device (13) are disposed behind the seedling planting device (3) configured as described above.

The fertilizer applicator (12) feeds the granular fertilizer stored in the hopper (14) with the feed roll (15), and feeds the fertilizer to the fertilizer ditches formed on the rice paddy with the ditcher (16) attached to the leveling float (8). It is configured to supply and fertilizes beside each planting strip. The feeding roll (15) is connected to the rotating case (9) by a crank link mechanism (1).
It is configured to be interlocked and connected via 7) and to feed out fertilizer in the same manner as the planting operation.

As shown in FIG. 6, the herbicide spraying device (13) is a perforated plate (19) in which the herbicide (S) in the form of granules stored in the hopper (18) is rotated in a certain direction around the vertical axis. Feeding hole (20)
And then the herbicide (S) filled in the feed hole (20) is sent downward through the supply pipe (21) and diffused by the rotating impeller (22) arranged below the herbicide, and the lower part is opened. Lower end opening (23
