Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a seeding device, and relates to a seeding device for simultaneously sowing a plurality of different kinds of seeds, such as feed crops for livestock.

(Prior art) Conventionally, there is a cultivation technology in which, for example, date corn and sorghum, which are seeds of livestock feed crops, are mixed and sown at the same time. They are placed side by side, and date corn is fed from one seed feeding section and sorghum is fed from the other seed feeding section for sowing.

Furthermore, as described in Japanese Patent Publication No. 52-117710, for sowing lettuce and carrot seeds one by one, a slide plate with a seed drop hole on one side is provided on the frame so that it can move forward and backward. A seed dispensing board having a plurality of seed dispensing holes of different sizes is rotatably provided on the slide plate, an outer hopper is provided on the seed dispensing board, and an inner hopper is provided, and the seed dispensing hole of the inner hopper is provided. The inner hopper can be moved back and forth so as to select one of the seed dispensing holes of the seed dispensing board, and the seed dropping hole of the slide plate is aligned with the seed dispensing hole selected by the inner hopper. Structures that do this are known.

(Problems to be Solved by the Invention) In the mixed seeding device described above, since a different number of seed dispensing sections are provided for each seed, the number of seed dispensing sections and the seed hopper that supplies seeds to these seed dispensing sections is As a result, the overall size of the seeding device becomes large, which requires time and effort to handle, and the structure becomes complicated, resulting in increased costs.Furthermore, there are problems in that it takes time and effort to measure the amount of feed between each seed.

In addition, in the structure described in the above publication, the seed outlet hole of the inner hopper is aligned with the seed outlet hole of the selected size of the seed feeder according to the size of the seed, and the seed outlet hole of the inner hopper is aligned with the seed outlet hole of the selected size of the seed outlet board. The seed drop hole on the slide plate is aligned with the position, and the seeds stored in the inner hopper are sown individually from this seed drop hole.In this case, the seeds are directly sown from the seed drop hole at the bottom of the inner hopper. Since the entire weight of the seeds stored in the inner hopper is concentrated in the seed outlet hole, the seeds may be damaged when the seeds are extracted.

The structure described in the above publication is intended to be used for sowing multiple types of seeds of different sizes using a single seed dispensing board having a plurality of seed dispensing holes. If you try to store seeds in the hopper and mix different types of seeds together with the seeds in the inner hopper, you will find that the inner hopper and the outer hopper are only provided with a slide plate on one side. Since it is not formed continuously up to the extraction part, if a large amount of seeds are stored in the outer hopper, the seeds in the outer hopper will constantly fall into the seed dispensing hole of the seed dispensing board, and the seeds selected by the inner hopper will It is true that the seeds in the inner hopper cannot fall into the seed dispensing hole of the dispensing plate, and as a result, different types of seeds interfere with each other, and different types of seeds are mixedly sown in an appropriate arrangement relationship. It is something that cannot be surpassed.

Therefore, the present invention was developed in view of these points, and it is possible to reliably mix and sow multiple types of seeds in an appropriate arrangement relationship, and the entire weight of the seeds stored in the seed hopper is concentrated in the seed dispensing part.
