[Prior Art]

 Conventionally, this seed suction type seeding machine is provided with a substrate having a placement surface on which a tray can be placed, a suction chamber and a suction box having a plurality of suction seeding openings that open to the chamber. Is supported by the support member so as to be movable up and down with respect to the base body through a vertical swinging member, and the swinging member extends between a seeding position in which the suction seeding port is directed downward and an adsorption position in which the suction seeding port is directed upward. It is supported so that it can turn, and the suction chamber is connected to a suction machine through a suction passage, and one side of the suction seeding surface where the suction seeding port of the suction box is formed is connected to the seeding surface. A seed tank is provided having an opening that opens toward the top, and the opening is at a higher position at the seeding position and at a lower position at the suction position.

When performing the seeding operation, the whole of the suction box is moved upward with respect to the base body by the vertical swinging member so that the tray is mounted on the mounting surface of the base body and the shaking is performed. The suction box is normally rotated in one direction with respect to the moving member, that is, the seeds stored in the seed tank are not dropped and discharged from the opening, and the opening is directed upward. Then, the suction box is turned to the suction position where the suction seeding port faces upward so that the seeds are sucked. That is, at the adsorption position, the opening of the seed tank is located on the lower side, so that the seeds in the seed tank are dropped and supplied from the opening onto the suction seeding surface which is directed upward in the suction box. In addition, since the suction force of the suction device is applied to the suction chamber via the suction passage, the suction action of the suction chamber causes the seeds to be adsorbed to the suction seeding ports.

As described above, after adsorbing the seeds to the suction seeding mouths, the suction box is rotated in the opposite direction to the seeding position in which the suction seeding mouths face downward. The seeds are then sown by reversing. In this case, the seeds that have not been adsorbed to the suction seeding ports during the reversal are returned from the openings into the seed tank, and when the suction box is reversed to the seeding position, the openings of the seed tanks are opened. The seeds returned to the seed tank are stored in the seed tank without dropping from the opening, and the suction box is seeded from the adsorption position. After being turned to the position, the suction box moves to a position above the tray via the swing member, and at this position, the suction chamber is opened to the atmosphere, The seeds adsorbed at each suction sowing mouth are sowed at each pot portion of the tray.

In the seeding operation described above, the tray is replaced with the placement surface of the base body every time the seeding into one tray is completed, and as described above, the suction box is attached to the shaking member for each tray. It is performed by moving the suction box in the vertical direction and rotating the suction box alternately between the suction position and the seeding position in the forward and reverse directions to repeat the turning operation.

[0006]

[Problems to be solved by the device]

 However, in the suction type seeder configured as described above, the support member is mounted upright on the base body, the vertical swing member is supported by this support member, and the suction box is rotated by this vertical swing member. Since the suction box is movably supported and is vertically movable with respect to the base body and is rotatable, the swing fulcrum of the vertical swing member is separated from the base body to the rear side. Therefore, the supporting member needs to have a shape projecting to the rear of the base, and the supporting member largely protrudes to the rear of the base, resulting in a large overall shape and a large working space. However, there was a problem that the number of people required for transportation and delivery also increased. In addition, the weight of the support member is increased due to the shape, and the handling thereof is complicated.

The object of the present invention is to make the whole shape compact, to work in a small space, to reduce the manpower during transportation and storage, and also to reduce the weight, which makes it easy to handle. The point is to provide a machine.
