Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a feeding roll of a seedling device for seedling raising boxes.

(Prior Art) Conventionally, it is known that an outer peripheral surface is formed with a feeding groove parallel to the axial direction and a slit orthogonal to the axial direction. The feeding groove has a role of holding and guiding seed paddy, and the slit has a role of picking seed paddy by fitting a scraping piece to the slit.

(Problems to be Solved by the Invention) Of the above-mentioned known ones, the feeding groove and the slit are formed depending on the feeling of experience, and since there is no special equation, the scraping effect may not be sufficient. .

 However, full performance is achieved with the following relationship.

 In other words, the length of seed rice is an intermediate product, about 7 mm.

Therefore, if the interval between the scratching slits is smaller than the length of the seed pad, the seed pad can be scratched in any case.

The feeding groove is about 290 mm because it is determined by the width of the nursery box. When seed paddy is placed side by side in this feeding groove, theoretically 290 m
According to the arithmetic calculation of m ÷ 7mm = 41.428 grains, about 41 grains will be arranged side by side. Actually, more than that, 54-60 grains are partially polymerized and lined up.

That is, since the edges are lined up little by little, the number becomes 54 to 60 grains. In this way, whether 54 or 60 grains are lined up,
If the gap between the slits is smaller than the length of the seed paddy, all grains can be scratched out.

(Means for Solving the Problem) Therefore, according to the present invention, the feeding groove 9 parallel to the axial direction is provided on the outer peripheral surface.
With the formation of the raking slit 16 orthogonal to the axial direction, the interval of the raking slit 16 is a feeding roll of a seedling box seeding device that is smaller than the length of the seed paddy 10. .

(Embodiment) Explaining one embodiment of the present invention with reference to the drawings, 1 is a seed padding hopper, and an inverted octagonal grain plate 2 or 3 is provided in the lower part of the seed padding hopper 1 to form a funnel 4. Reference numeral 5 is a supply port provided in the lower portion of the funnel 4, and 6 is a supply amount adjusting plate of a supply amount adjusting device 7 attached to the seed paddy hopper 1.

One of the grain plates 2 is made short and the other grain plate 3 is made long so that the lower end of the grain plate 3 is brought close to the outer peripheral surface of the horizontal axis feeding roll 8.

The horizontal axis feeding roll 8 is provided below the short grain plate 2. On the outer peripheral surface of the horizontal-axis feeding roll 8, horizontal-line-groove-shaped feeding grooves 9 parallel to the generatrix direction are formed all around with a desired interval. In this embodiment, about 90 feeding grooves 9 are formed.
The feeding groove 9 is formed to have a width such that the seed paddy 10 fits laterally in one row. When the feeding groove 9 is viewed from the side, the rotation advance side 11 is
An inclined surface 12 is formed by notching the corner portion, and the reverse rotation side 13 is formed in a standing wall 15 having a corner portion 14. The inclined surface 12 is formed as an inclined surface which becomes lower from the rotation forward side 11 to the rotation backward side 13. In this embodiment, although it is inclined horizontally,
You may incline in an arc shape.

Further, on the outer peripheral surface of the horizontal axis feeding roll 8, scratching slits 16 are provided on the entire circumference at desired intervals in the left-right direction. The raking slit 16 is formed to have the same depth as or a little deeper than the feeding groove 9, and a raking piece 17 is fitted into each raking slit 16.

Therefore, the interval between the scraping slits 16 is made smaller than the length of the seed paddy 10.

That is, when the length of the feeding groove 9 is set to about 290 mm, the length of the seed pad 10 is about 7 mm in the intermediate product, so the seed pad 10 in the feeding groove 9 is 290 mm ÷ 7 mm = 41.428 arithmetic calculation Then, about 41 grains will be lined up horizontally.

However, in reality, the number of seeds 10 is more than that, and the edges of seed rice 10 are lined up so that the seeds are gradually overlapped with each other, so that the number of seeds is 54 to 60.
If you set it based on the length of 10, the slit for scraping
The number of 16 is about 41 with respect to the length of the feeding groove 9 and the length of the seed pad 10 is unchanged. Be sure to polymerize with 16,
The scraping piece 17 allows scraping.

Then, the funnel 4 located above the horizontal axis feeding roll 8
A first rotating brush 18 is provided in the vicinity of the supply port 5. A second rotating brush 19 is provided at a position above the horizontal axis feeding roll 8 on the front side of the first rotating brush 18.

Both the first rotary brush 18 and the second rotary brush 19 have an action of sweeping back the seed paddy 10 which rotates in the opposite direction of the horizontal axis feeding roll 8 and rotates together with the horizontal axis feeding roll 8, and the second rotary brush 19 is It has the effect of leveling the seed rice 10 and the action of taking out the seed rice 20 with awns.

The first rotary brush 18 is formed to have a smaller diameter than the second rotary brush 19, and has a gap 22 below the grain plate 2,
The rotary shaft 21 is axially attached to the side plate 23 of the seeding device.

The gap 22 allows the seed paddy 10 swept back by the second rotary brush 19 to jump over the first rotary brush 18 and reach the lower end of the grain board 3.

The central shaft 24 of the second rotary brush 19 is pivotally mounted on the arm 35, and the base of the arm 35 is pivotally mounted on the horizontal shaft 36 pivotally mounted on the side plate 23. A height adjusting device 25 for adjusting the height of the second rotary brush 19 is provided at the tip of the arm 35.

Reference numeral 26 is a paddy box of the seed rice 20 with awns taken out from the rotation advancing side 11.

A seed paddy guide cover 27 is provided on the side surface of the horizontal axis feeding roll 8. The seed padding guide cover 27 has the function of guiding the seed paddy 10 fitted in the feeding groove 9 from the upper position to the lower position so as not to damage it. The sponge 28 provided inside is applied to the outer peripheral surface of the horizontal shaft feeding roll 8. Contact.

28 is a motor for driving the horizontal axis feeding roll 8, the first rotary brush 18, and the second rotary brush 19, 30 is an adjusting knob for adjusting the rotation of the motor 28, and 31 is below the lower end of the grain board 3. The scraper is provided to prevent the seed paddy 10 from falling by bringing the tip end thereof close to the outer peripheral surface of the horizontal axis feeding roll 8. Reference numeral 32 is a horizontal transfer table having a transfer roll 34 for transferring the seedling raising box 33, and 37 is a partition plate provided on both left and right sides of the horizontal axis feeding roll 8.

In addition, a paddy guide that moves up and down by a parallel link may be provided below the horizontal axis feeding roll 8. In this case,
Vertical strips can be sown in nursery boxes.

(Operation) Next, the operation will be described.

The seeds 10 are put into the seed paddy hopper 1, and the feed amount adjusting plates 6 at the lower ends of the grain plates 2 and the grain plates 3 are adjusted to desired positions,
Horizontal axis feeding roll 8, first rotating brush 18, second rotating brush
When 19 are rotated and the seedling raising box 33 is transferred by the horizontal transfer table 32, the seed rice 10 that has flowed down on the grain plate 3 of the funnel 4 fits into the feeding groove 9.

In this case, when the feeding groove 9 is viewed from the side, the rotation forward side 11
Forms a slope 12 by notching its corners, and
Since 13 is formed on the upright wall 15 having the corner portion 14, the seed pad 10 is the feeding groove 9 which is raised by the rotation of the horizontal axis feeding roll 8.
The slanted surface 12 fits smoothly into the feeding groove 9, and the standing wall 15 abuts on the seed paddy 10 to raise the seed paddy 10.

Then, the funnel 4 located above the horizontal axis feeding roll 8
The first rotary brush 18 is provided in the vicinity of the supply port 5 of the first rotary brush 18, and the second rotary brush 19 is provided above the horizontal shaft feeding roll 8 on the front side of the first rotary brush 18. Since the rotating brush 18 and the second rotating brush 19 are rotating in the opposite direction to the horizontal axis feeding roll 8, most of the seed paddy 10 that rotates together with the horizontal axis feeding roll 8 is swept back by the first rotary brush 18, The seed rice 10 that has passed through the lower part of the one-rotating brush 18 and is not fitted in the feeding groove 9 is surely leveled and swept back by the second rotating brush 19.

The first rotary brush 18 has a gap 22 below the grain plate 2 and has its rotary shaft 21 attached to the side plate 23 of the seeding device.
The second rotating brush is attached to the second rotating brush.
Since the seed pad 10 swept back by 19 jumps over the first rotating brush 18 through the gap 22 and returns to the grain plate 3, the seed pad 10 between the first rotating brush 18 and the second rotating brush 19 is reduced. Then, it is securely fitted into the feeding groove 9. Further, the seeded paddy 20 is hooked at the tip of the second rotary brush 19 and ascended to the paddle box.
Taken out on 26.

Then, the seed pad 10 fitted into the feeding groove 9 passes below the second rotary brush 19, and the sponge 28 of the seed pad guide cover 27 is provided.
It is guided to the bottom without spilling due to, falls downward at the lowest point, and is sown in the seedling raising box 33.

In this case, since the spacing between the raking slits 16 is smaller than the length of the seed paddy 10, the relationship between the feeding groove 9 and the raking slit 16 is such that the length of the feeding groove 9 is about 290 mm. Then, the number of the slits 16 for scraping is about 41, and the end of the seed paddy 10 is gradually overlapped with the inside of the feeding groove 9.
Even if 54 to 60 grains are fitted, the length of seed pad does not change, so the slit 16 for scraping overlaps with the seed 10 and the scraping piece 17 fitted to the slit 16 for scraping Be sure to make contact with seed pad 10.

Therefore, the seed paddy 10 in the feeding groove 9 can be surely scratched out, and seeding can be surely performed.

(Effect) In the present invention, in the outer peripheral surface, the feeding groove 9 parallel to the axial direction and the raking slit 16 orthogonal to the axial direction are formed, and the spacing between the raking slits 16 is the seed pad 10. Since it is a feeding roll of a seeding device for a nursery box having a length smaller than the length, all grains can be scraped regardless of the number of grains.
