Description

Detailed Description of the Invention [Industrial applications]

TECHNICAL FIELD The present invention mainly relates to a fine seed sorting / feeding device that separates fine seeds such as cabbage, Chinese cabbage, and lettuce into individual grains, so that the individual grains can be reliably taken out and sown.

[Prior art]

In the case of sowing, the above-mentioned fine seeds are often manually sown, and even in that case, it is difficult to count the number of seeds. In order to mechanically sow the seeds with precision, various types such as a method of coating seeds for easy handling, a method of using static electricity, a negative pressure suction type, and a hameai type have been proposed.

[Problems to be Solved by the Invention]

The coating of fine seeds facilitates counting and enables high-precision mechanical seeding, but has a problem of high cost. Further, in the seeding device for fine seeds such as electrostatic type, negative pressure suction type, and hameai type, the seeds are different in shape, weight, and size depending on the type of the vegetable, and the seeds are sorted and selected one by one. However, it was difficult to improve the seeding accuracy.

[Means for solving problems]

The present invention has been made to solve the above problems, in the inclined separation shelf vibrated by the vibrating body, the rising slope portion and the downward slope portion are provided continuously, on the starting end side of the rising slope portion. The supplied seeds are separated by vibration while being separated and discharged from the tip of the descending slope, and a trough that moves the seeds in a row is formed continuously from the rising slope to the descending slope. However, the present invention is characterized in that a seed selection mechanism for accurately selecting seeds discharged from the trough at the tip of the descending slope portion one by one through a sensor, a shutter and the like is provided.

[Action]

With the above-described configuration, the present invention can sort and seed any seed individually and surely.

【Example】

Embodiments of the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 denotes a seed hopper, which mainly accommodates fine seeds such as cabbage, Chinese cabbage, lettuce, etc., and discharges them by a predetermined amount through a shutter. A vibrating seed sorter 2 is provided on the side. The vibrating seed sorter 2 includes a vibrating body 3 and the vibrating body 3
And a sorting shelf 4 to which vibration is applied, and the sorting shelf 4 has a rising slope 4a and a descending slope in the length direction.
4b are provided, and a plurality of rows of troughs 5 are formed in the width direction across both the inclined portions 4a and 4b. Seeds S overlap two or more grains in the trough 5 on the side part in the middle of the trough 5. Seed drop openings 6 and 6 are provided for dropping one seed of the foreign matter and foreign matter while moving with the foreign matter and foreign matter. A single grain selection device 7 is provided below the tip of the downward slope 4b. In this grain device 7, a shutter 9 is provided in the middle of a seed passage 8, a reducing passage 10 is formed corresponding to the shutter 9, and a seed discharge pipe 11 is continuously provided below the seed passage 8. There is. Seed sensors 12, 1 composed of optical sensors are provided between the tip of the descending inclined portion 4b and the upper end of the seed passage 8 and in the passage of the seed passage 8 below the shutter 9.
Three are provided. The seed sensors 12 and 13 and the shutter 9 are linked to each other by a sequence program, and their reactions are forcibly accelerated. In addition, the washing of the return passage 10 and the discharge end of the funnel-shaped guide plate 13 provided below the seed drop opening 6 face the upper surface of the return conveyor 14, and the return conveyor 14 and the guide passage 13 guide each other. The seeds S discharged from the plate 13 are returned to the seed hopper 1. The tip of the seed discharge pipe 11 has a seeding hole.
It faces 15. In the seed paper manufacturing apparatus configured as described above, the seed S group discharged from the seed hopper 1 onto the sorting shelf 4 of the vibrating seed sorting apparatus 2 is stored in the sorting shelf 4 vibrated by the vibrating body 3. Ascends along the trough 5 on the ascending slope 4a, and if two or more seeds are piled up in the middle of the trough 5 or if there is any foreign matter, leave one seed and drop it from the seed drop opening 6 to raise the seed S. 1 when reaching the end of the inclined part 4a
It is separated into grains and the intervals are almost constant.
Then, when the seed S reaches the downward slope 4b, the seed S further descends with a further interval, and falls from the tip of the downward slope 4b into the seed passage 8 of the single grain selecting device 7. The falling seed S is detected by the seed sensor 12 and discharged from the seed discharge pipe 11 to the seeding hole 15 through the seed passage 8. At this time, the seed sensor 13 detects the seed S.
While the seed S is in the seed accommodation hole 15, the shutter 9 is closed and the seed is discharged onto the reduction conveyor 14 through the reduction passage 10 and returned to the seed hopper 1 by the reduction conveyor 14. In addition, seeds and foreign matters dropped from the seed drop opening 6 are brought from the guide plate 13 to the reduction conveyor 14 and the seed hopper 1
The impurities may be removed during this process.

【The invention's effect】

As described above, according to the fine seed sorting / feeding apparatus of the present invention, the rising and falling slopes provide the vibrating sorting shelf with the troughs, and the seeds of any size, shape, and weight can be seeded one by one. It can be sorted and sent out. In particular, even fine seeds that could not be conventionally counted by humans can be reliably separated into individual grains. In addition, a sensor that collects the seeds released from the vibration sorting shelf
Since it is possible to select each grain by shutter etc.,
The seeds can be surely seeded at a predetermined position one by one.
