Description

[Technical field]

[0001] The present invention relates to a sprayer that is attached to a harrow device in which the harrow movable part can be folded relative to the harrow fixed part. [Background technology]

[0002] As farmers age and scale-up of farms increases, interest in flooded direct seeding, a labor-saving, low-cost rice production technique, is growing. In order to further reduce labor and costs in flooded direct seeding cultivation, the inventors developed a shallow soil seeding machine that can be attached to a non-foldable harrow with a width of 2.0 to 2.6 m and puddle at the same time. However, farmers have requested the development of a more general-purpose seeding machine that can be attached to a folding harrow, which is both large-sized and can be driven on public roads. Therefore, the inventors invented an attachment mechanism for a seeder (width 2.5 m or less) that can be attached to a folding harrow and allows it to be driven on public roads without applying to the police station, and a mechanism to limit the harrow's range of motion (Patent Document 1). In the seeder of Patent Document 1, the harrow can be opened and closed by extending the mounting arm for the pressure roller and removing the hose that guides the seeds. In addition, in the seeder of Patent Document 1, the mounting arm for the pressure roller can be shortened during sowing work, thereby ensuring the inclination angle of the hose and making it easier to prevent seeds from becoming stuck. In addition, in the seeder of Patent Document 1, the mounting arm for the suppression roller, which is perpendicular to the mounting arm for the suppression roller, is extendable and contractible in the horizontal direction, so that the overall width can be narrowed when traveling on public roads. In addition, in the seeder of Patent Document 1, a hose holding section is provided on the mounting arm for the pressure roller, allowing the hose and hose holding section to be easily attached and detached, so that the hose can be removed when opening and closing the harrow to avoid interference. In addition, in the seeder of Patent Document 1, the pressure roller is divided into three parts, a central roller and end rollers, which are installed so that they do not interfere with each other and overlap horizontally so that there are no areas between the rollers where the rollers do not act. The seeder of Patent Document 1 is converted from the state during sowing to the state for driving on a public road as follows. Remove the hose from the hose holder. Retract the hopper mounting frame and move the hopper to the center. Extend the mounting arm for the suppression roller to the rear. Fold the harrow movable part halfway. Retract the mounting arm for the suppression roller. Fold the mounting arm for the suppression roller upward and inward. Patent Document 2 discloses a hopper, a delivery device, a guide funnel, a conduit, a guide pipe, and a suppression roller that are attached to a rotary tiller mounted on the rear of a tractor. In Patent Document 2, a hitch provided at the front end of a seeding machine is fixed with a pin to the rear end of a tail wheel mounting frame of the rotary tiller. In addition, a seeding frame is detachably fixed to the mounting beam of the seeding machine, and the seeding frame and bracket are detachable by a detachment pin. A roller frame is attached to the bracket, and a suppression roller is attached to the roller frame. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2021-180650 A [Patent Document 2] A microfilm of the specification and drawings attached to the application for Utility Model Application No. 61-77830 (Utility Model Application Publication No. 62-190411) (issued by the Japan Patent Office on December 3, 1987) Summary of the Invention [Problem to be solved by the invention]

[0004] In the seeder of Patent Document 1, two people are needed to change from the sowing state to the running state or the transport state, and because the mounting arm for the suppression roller and the suppression roller are heavy, strength is required, and there are many steps and the work takes a long time. In addition, because the mounting arm for the heavy suppression roller protrudes backward, the center of gravity is biased backward, and the front wheel load of the tractor is reduced, making it difficult to work stably. In addition, because the shape of the harrow side where the mounting arm for the suppression roller is attached, the length of the harrow moving part, and the trajectory of the harrow moving part differ depending on the model, there is a problem that it is highly likely that the mounting arm for the suppression roller will have to be redesigned for each harrow model. Therefore, there is a demand for a seeder that can easily attach and detach the suppression roller and the hose that guides the seeds when the harrow movable part is folding, without using an attachment arm for the suppression roller. It should be noted that the rotary tilling device in Patent Document 2 does not perform a folding operation, but merely allows the sowing frame and the roller frame to be attached and detached.

[0005] The present invention aims to provide a sprayer that is attached to a harrow device in which the harrow movable part can be folded relative to the harrow fixed part, and that allows the attachment and detachment of hoses that guide the suppression members and objects to be sprayed when the harrow movable part is folded, without using an attachment arm for a suppression roller to attach all of the suppression members.
