Through the
During the seeding operation, the suction box is moved upward with respect to the base to place the tray on the mounting surface of the base, and the suction box is turned so that the suction seeding port is positioned at the suction position where the suction seeding port is directed upward. Then, in such a state, the seeds dropped onto the suction sowing surface are adsorbed to the suction sowing port by the suction action of the suction machine, and then the suction box is moved to a seeding position where the suction sowing port is directed downward. The suction box is moved to the seeding position above the tray, the suction chamber is opened to the atmosphere, and the seeds adsorbed on the suction seeding port are sown in each pot of the tray.

[0003]

However, in the conventional suction seeder described above, the suction box is supported so as to be able to turn 360 degrees with respect to the base via a supporting member. When turning from the position to the suction position where the suction sowing surface is directed upward, the seeds dropped on the suction sowing surface are likely to turn too much from the suction position, and the seeds dropped on the suction sowing surface, that is, from the suction box to the outside. There is a problem of dropping, and when turning from the seeding position to the suction position or reversing from the suction position to the seeding position, the turning operation is extremely performed because the outer wall of the suction box is held. Had a difficult problem. The purpose of the present invention is to prevent the suction box from turning beyond the suction position when the suction box is turned from the seeding position to the suction position, and also to easily perform the turning operation of the suction box. To provide a seeding machine.

In addition to the provision of the seed tank 23 in which f is an upper rank, a handle 6 that interferes with the support member 2 is provided on a side surface of the suction box 2 facing the mounting side of the seed tank 23.

[0005]

With the above arrangement, when performing the seeding operation, the suction box 2 is moved upward with respect to the base 1 to place the tray T on the mounting surface 10 of the base 1, while the suction box 2 is moved upward. By gripping the handle 6 of the suction box 2 and rotating the suction box 2 with respect to the base 1, the suction box 2 can be easily turned to the suction position where the suction seeding port 22a is directed upward, and When the suction box 2 turns to the suction position,
The handle 6 interferes with the support member 3 to prevent the suction box 2 from turning beyond the suction position, and the interference can be used to maintain the suction box 2 at the suction position. Therefore, the seeds can be easily adsorbed to the seeding port 22a at this adsorption position, and the seeds do not fall off. That is, when the suction box 2 is turned to the suction position, the opening 22f of the seed tank 23 provided on one side of the suction seeding surface 22 of the suction box 2 is lower, and the seeds in the seed tank 23 are opened. Since the seeds can flow down from the portion 22f to the suction seeding surface 22 and can be sucked into the suction seeding port 22a by the suction action of the suction device 5, the grip 6 can maintain the suction position. 23
It is possible to prevent the seeds flowing extra from falling off at the time of turning over the adsorption position of the adsorption box 2, and therefore,
The work of adsorbing the seeds can be made easier. After the suction, the suction box 2 is inverted so that the suction seeding port 22a faces downward. In this case, the suction box 2 can be inverted using the handle 6.

Next, the suction box 2 is swung upward with respect to the base 1 through the swinging portion 40 as shown by the imaginary line in FIG. 2, and the base 1 is placed under this state. The tray T is placed at a predetermined position on the surface 10 via the guide pins 11.

Then, the suction box 2 is rotated in the upward swinging position in the direction indicated by the imaginary line in FIG. 2 so that the suction seeding plate 22 is positioned on the upper surface side as shown in FIG. Then, since the opening 23f of the seed tank 23 moves to the lower position, the seeds in the seed tank 23 are sucked from the opening 23f through the inclined surface portion 22b by the suction sowing plate 2.
2, and the seeds located near each suction sowing port 22a by the suction action at each suction sowing port 22a of the suction sowing plate 22 are adsorbed to each suction sowing port 22a.

When performing such a suction operation, the suction box 2
Since the handle 6 is provided on the front wall 20c, the suction box 2 can be easily turned to the suction position by gripping the handle 6 and rotating the suction box 2, and When the suction box 2 rotates to the suction position, the handle 6 interferes with the upper surface of the forked portion 42a of the swinging part 40 and can prevent the suction box 2 from turning beyond the suction position.
Thereby, it is possible to reliably prevent the seeds flowing down to the suction sowing plate 22 from falling off from the suction sowing plate 22, that is, the suction box 2, because the suction box 2 is turned too much more than the suction position. is there. After the suction is completed, the suction box 2 is rotated in the solid line direction in FIG. 1 so that the suction seeding plate 22 is positioned so as to be located at a seeding position in which the suction seeding plate 22 is directed downward. Also in this case, the suction box 2 can be turned from the standing position to the seeding position by using the handle 6, whereby the inversion from the suction position to the seeding position can be easily performed. In addition, only the seeds sucked by the suction sowing port 22a remain on the suction sowing plate 22 due to the reversal of the suction box 2, and the seeds that are not sucked by the suction sowing port 22a pass through the inclined surface portion 22b. It is stored again in the seed tank 23 through the opening 23f.

After that, the suction box 2 is swung downward to move the suction box 2 to a position directly above the tray T. First, the front end of the suction box 2 is moved to the front receiver 11. After that, the rear seed tank 23 of the suction box 2 is moved to the rear receiver 1.
It is supported on the upper part of 3,13. Then, the operation switch 16 of the suction device 5 is turned off to stop the suction by the suction device 5, and the closing plates 25, 25 are lifted by the operation portions 25a, 25a to lift the air release holes 24, 25.
24 is opened, and the suction chamber 21 is opened to the atmosphere.
The seeds adsorbed on a can be sown in each pot P of the tray T.

In the above embodiment, the supporting member 3 is formed of a hollow member, and the supporting member 3 is provided with the suction passage A for communicating the suction machine 5 and the suction chamber 21. Needless to say, the structure may be such that the suction member 5 and the suction chamber 21 communicate with each other via a suction hose, without forming the support member 3 by a hollow member.

[0025]

As described above, according to the present invention, the substrate 1 having the mounting surface 10 on which the tray T can be mounted, a suction chamber 21 and a plurality of suction seeding ports 22a opened to the suction chamber 21 are provided. A box 2 and the suction box 2

And a suction passage A which communicates the suction machine 5 with the suction chamber 21.
At one side of the suction sowing surface 22, a seed tank 23 which is open toward the sowing surface 22 and has an opening 22f higher in the sowing position is provided, and the seed tank 23 in the suction box 2 faces the mounting side of the seed tank 23. Since the handle 6 that interferes with the support member 2 is provided on the opposing side surface, when the suction box 2 is turned from the seeding position to the suction position or turned from the suction position to the seeding position, the handle 6 is easily used. The suction box 2
Is turned from the seeding position to the suction position, and the suction seeding port 2 is rotated.
When the suction box 2 is turned to the suction position when the suction box 2a is located at the suction position, the handle 6 interferes with the support member 3 and can prevent the suction box 2 from turning beyond the suction position.
By utilizing the interference, the suction box 2 can be maintained at the suction position, and as a result, the seeding port 2 can be maintained at this suction position.
Adsorption of the seed to 2a can be easily performed without falling off of the seed. That is, when the suction box 2 is turned to the suction position, the opening 22f of the seed tank 23 provided on one side of the suction seeding surface 22 of the suction box 2 is lower, and the seeds in the seed tank 23 are opened. Since the seeds can flow down from the portion 22f to the suction seeding surface 22 and be sucked into the suction seeding opening 22a by the suction action of the suction device 5, the grip 6 can maintain the suction position. It is possible to prevent the seeds flowing excessively from 23 from dropping off by the rotation of the adsorption box 2 at a position higher than the adsorption position, so that the operation of adsorbing the seeds can be made easier. Thereby, it is possible to prevent the seeds flowing down to the suction seeding surface 22 from falling from the seeding surface 22, that is, the suction box 2, by turning the suction box 2 above the suction position.
