Description

[Detailed description of the invention] This invention is a device used for sowing rice seed clusters one by one at appropriate intervals vertically and horizontally in seedling boxes, etc. Then, five groups of recesses are arranged at suitable intervals in the roll rotation direction and the rotation axis direction to accommodate each seed grain supplied in the hopper in a vertical position with its longitudinal direction along the roll rotation direction. The present invention relates to a seeding device formed.

This type of conventional seeding device is configured to directly supply seed rice to the outer circumferential surface portion of the feed roll over an appropriate length range in the rotational direction by a simple flowing down action from the bottom of the hopper. In this case, since the postures and feeding intervals of the seed rice supplied to the recessed portions of the feed roll are inconsistent, supply leakage is likely to occur due to the seed rice being caught on the periphery of the recessed portions, and In some cases, multiple seeds are supplied to the container, and in that case, the seeds protrude from the recesses, so all the seeds are scraped by the leveling action of a roll brush, etc. installed on the lower side of the supply. There are cases where the seed rice is not supplied to the recess after being taken out, which has the drawback of increasing the incidence of missing plants overall.

The object of the present invention is to remedy the above-mentioned drawbacks with simple modifications.

The characteristic structure of the seeding device of the present invention, which has been made to achieve such an object, is that the seed rice is placed at the bottom of the hopper in a state close to the outer circumferential surface of the roll over an appropriate length range in the rotational direction of the feed roll. The point is that a guide is provided for correcting the above-mentioned vertical posture.

In other words, even if the posture and feeding interval of the seed rice supplied from the hopper to the feed-out roll side vary, the guide provided close to the outer peripheral surface of the feed-out roll allows the seed rice to maintain a posture corresponding to the recess. Since the feeding interval can be corrected, it is possible to prevent, as much as possible, the situation where the seed rice is not fed due to getting caught on the peripheral edge of the recess, or the case where a plurality of seeds are fed to one recess. .

Therefore, without installing a special feeding device for dot seeding in the hopper, by simply and inexpensively modifying the hopper by simply providing a guide as described above near the outer circumferential surface of the feeding roll, it is possible to eliminate or reduce the occurrence of stock shortages. We were able to sow seeds in good conditions.

Hereinafter, embodiments of the present invention will be described based on the drawings.

Seedling box B placed and transported on belt conveyor A
To construct a device C for sowing rice grains one by one at appropriate intervals vertically and horizontally, a pair of left and right hoppers 2 are attached to a bracket 1A erected from the frame 1 of the belt conveyor A. Attach the support frames 3, 3,
A feed-out roll 4 rotatably constructed over 3
Five groups of recesses are formed on the outer circumferential surface of the container at suitable intervals in the roll rotation direction and the rotation axis direction, in which each grain of seed rice can be stored in a vertical position with its longitudinal direction along the roll rotation direction. At the same time, a chute 6 is provided at the lower part of the hopper 2 to guide the seed rice in the hopper 2 downward toward the upper side of the pay-out roll 4 and toward the outer circumferential surface of the upward rotation path.

Further, a fixed guide 7 for guiding the transfer of the seed rice is provided on the support frames 3, 3 along the outer peripheral surface of the roll on the side of the rotation transfer path of the seed rice by the feed roll 4, and at the entrance of the fixed guide 7, a tip thereof is provided. A rotating brush 8 for scraping out surplus rice seed is provided which is driven and rotated in a state where it is in sliding contact with the top of the outer circumferential surface of the feed roll 4.

Each of the five groups of recesses of the feed roll 4 is curved so that it becomes shallower toward the lower side in the rotational direction when viewed in the direction of the rotation axis, and has a boat shape in which the width becomes narrower toward the lower side in the rotational direction when viewed from above. It is composed of

Therefore, over an appropriate length range in the rotational direction of the feed roll 4, in other words, from the downstream end of the chute 6 to a location corresponding to the attachment of the rotary brush 8, it is close to the outer circumferential surface of the feed roll 4. A guide 9 is provided for correcting the seed rice to the above-mentioned vertical orientation in the state where the seed rice is in the vertical position. The guides 9 are composed of piano wires arranged in parallel with an interval larger than the width of the seed rice and smaller than the vertical width.

Even if the posture of the seed rice supplied from the hopper 2 to the payout roll 4 side via the chute 6 and the adjacent spacing in the direction of the roll rotation axis are different, the guide 9 allows the seed rice to be placed in a posture corresponding to the recess 5 and adjacent to the rice seed. The interval can be corrected.

Further, a support frame 3 of the hopper 2 equipped with the feed roll 4, the chute 6, and the rotating brush 8,
3, the feeding roll 4 and the rotating brush 8
The other bracket 1B installed upright on the frame 1 has a bolt 10 fixed to the support frame 3 and a bolt adjustably screwed into the bracket 1B. 11, a stopper 12 that restricts the downward movement of the support frames 3, 3 on the feed roll 4 side is pivotally mounted, and as a result,
The entire hopper 2 is configured to be able to move automatically over the front and back both walls of the seedling growing box B by swinging upward as it comes into contact with the seedling growing box B.

Incidentally, a mechanism for imparting vibration to the chute 6 may be provided.
