Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a feeding roll of a seeding device for a nursery box.

(Prior Art) In the publicly known Japanese Patent Laid-Open No. 145117/1982, a large number of feeding grooves parallel to the axial direction are provided on the outer peripheral surface of a horizontal-axis cylindrical feeding roll with a predetermined interval at substantially the same width. The feeding roll of the seeding apparatus for the formed nursery box is described.

Further, in the conventionally known JP-A-60-196104, a concave portion for fitting a plurality of seed paddyes for one plant is formed on the outer peripheral surface, and a raking slit orthogonal to the feeding concave portion is formed, A structure in which a scraping body is fitted in the scraping slit is described.

(Problems to be Solved by the Invention) The one described in JP-A-52-145117 is a long feeding groove having a mere horizontal line groove shape, and the seed pad 1 is laterally arranged.
Since it is not in the shape of a horizontal groove that fits in rows, a plurality of seeds may overlap and fit into each other to be clogged in the groove, resulting in a problem that accurate seeding cannot be performed. Further, in the above-mentioned known device, the seed roll cannot be scraped because the scraping slit in the direction orthogonal to the axial direction is not provided on the outer peripheral surface of the feeding roll.

Further, since the one described in JP-A-60-196104 is configured by simply forming a large number of feeding recesses into which seed rice fits, not only the roll itself is expensive, but also the feeding recesses are formed. Since the seed paddy does not fit smoothly and a plurality of seed paddles may be fitted side by side in the feeding recessed portion, at that time, since the raking body acts between the left and right seed paddies, the seed paddy is applied. There is a problem that the raking body may not work properly, and a problem that the seed pad may not be able to be raked because of insufficient research on the slit width of the raking slit.

That is, from the viewpoint of manufacturing, the payout roll in which a large number of payout grooves parallel to the axial direction are formed on the outer circumferential surface of the horizontal axis cylindrical payout roll at a predetermined interval is the cheapest, so this structure Then, we would like to solve various problems. Then, when forming a raking slit on the roll, if the interval is formed to be shorter than the length of the seed pad, since a part of the seed pad always faces the raking slit, the raking pad is used in any case. The scraping body fitted in the slit acts. If the width of the scraping slit is larger than 1.0 mm, the relatively soft sprouts of the sprouted seed pad may be fitted, and the scraping body may not be removed even if it acts. The width of is set to 0.6 mm to 1.0 mm to prevent seed paddy from fitting.

(Means for Solving the Problems) Therefore, according to the present invention, a large number of feeding grooves 9 parallel to the axial direction are formed on the outer peripheral surface of the horizontal-axis cylindrical feeding roll 8 at a predetermined interval at substantially the same width. , The feeding groove 9 is formed in a long horizontal groove shape so that the seed rice 10 can be fitted in one row in a horizontal direction,
Scratching slits 16 in a direction orthogonal to the axial direction are formed on the outer peripheral surface of the feeding roll 8 at intervals in the axial direction,
In the one in which a scraping body 17 is fitted in the scraping slit 16, an interval between the scraping slits 16 in the axial direction is such that a part of the seed rice 10 in the lateral direction is the scraping slit 16 without fail. Formed at a slightly narrower interval than the length of the seed rice 10 to face the, the slit width of the scratching slit 16, the seed rice 10 seeding for seedling box formed in 0.6mm ~ 1.0mm so as not to stick to it. This is the delivery roll of the device.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings, in which 1 is a seed padding hopper, and the seed pad feeding hopper 1 is provided with inverted octagonal grain plates 2 and 3 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 at an inclined position. 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 at desired intervals over substantially the entire width.

The width of the feeding groove 9 in the circumferential direction is formed so that the seed paddy 10 fits laterally in one row. In FIG. 3, 11 is a rotation forward side, 13 is a rotation reverse side, and rotates leftward from the rotation reverse side 13 toward the rotation forward side 11, but the rotation forward side 11 of the feeding groove 9 has a corner portion thereof. Is cut out to form an inclined surface 12, 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. The inclined surface 12 is linear in this embodiment, but may be arcuate.

However, on the outer peripheral surface of the horizontal axis feeding roll 8, the fourth
As shown in FIG. 5 and FIG. 5, the seed paddy is moved in the left-right direction (generic direction).
Scratching slits 16 that are orthogonal to the generatrix direction are provided at intervals slightly smaller than the length of 10, and a scraping body 17 is fitted into each of the scraping slits 16. The spacing slightly narrower than the length of the seed paddy 10 means that the left and right spacings of the raking slits 16 are shorter than the length of the seed paddy 10, so that the seed paddy is as shown in FIG.
Even if 10 are polymerized, even if they are lined up one by one as shown in Fig. 5, in each case, a part of the seed pad 10 will face the slit 16 for scraping, so be sure to use the scraped body. It means that the scraping action of 17 will be received.

The depth of the scraping slit 16 is the same as or slightly deeper than that of the feeding groove 9, and the slit width thereof is a soft sprout seed paddy.
The size is set to 0.6 mm to 1.0 mm so that 10 does not fit. That is, the seed pad 10 uses sprout paddy, but if the slit width of the scratching slit 16 is set to about 1.2 mm, the seed pad 10 that has become soft can not be removed even if the scratch pad 17 acts firmly. There is a possibility that seed paddy 10 will never fit 0.
It is formed to 6 mm to 1.0 mm.

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. The horizontal axis feeding roll 8 on the front side of rotation of the first rotary brush 18
A second rotating brush 19 is provided at a position above.

The first rotating brush 18 and the second rotating brush 19 both rotate in the opposite direction to the horizontal axis feeding roll 8 and have an action of sweeping back the seed paddy co-rotating with the horizontal axis feeding roll 8. The brush 19 has a function of leveling the seed rice 10 and an 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 its rotary shaft 21 is axially attached to the side plate 23 of the seeding device so as to have a gap 22 below the grain table 2. Install.

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 attached to the arm 35, and the base of the arm 35 is pivotally attached to the lateral shaft 36 pivotally attached to 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.

29 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 at a position below the horizontal axis feeding roll 8, and in this case, vertical seeding can be performed in a seedling raising box.

(Operation) Next, the operation will be described.

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

In this case, the feeding groove 9 is the rotation forward side when viewed from the side.
11, the corner is cut away to form an inclined surface 12, and the rotation reverse side 13 is formed on the standing wall 15 having the corner 14,
The seed pad 10 is fitted so as to smoothly slide into the feeding groove 9 by the inclined surface 12 of the feeding groove 9 that rises due to the rotation of the horizontal axis feeding roll 8, and the standing wall 15 abuts the seed pad 10 so that the seed pad 10 is fixed. It is raised and fits orderly in the feeding groove 9 in a row in the lateral direction. Therefore, the seeding amount can be made accurate.

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 outer circumference of the horizontal axis feeding roll 8 is provided with a slit 16 for feeding, which is orthogonal to the direction of the mother ship, at an interval shorter than the length of the seed paddy 10 in the left-right direction, the feeding slit 16 shown in FIG. As shown in FIG. 5, the seed pad 10 is always fitted so as to face the feeding slit 16 and the width of the slit of the picking slit 16 is formed to be 0.6 mm to 1.0 mm. The scraping body 17 engaged with the scraping slit 16 without engaging with the scraping slit 16 acts to scrape all the grains.

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, the feeding groove 9 is provided on the outer peripheral surface of the horizontal-axis-shaped cylindrical feeding roll 8 at a predetermined interval and extending over substantially the entire width and parallel to the axial direction.
The feeding groove 9 is formed in a long horizontal groove shape so that the seed rice 10 can be fitted in one row in a horizontal direction, and the feeding groove 8 is formed on the outer peripheral surface of the feeding roll 8 in a direction orthogonal to the axial direction. The slits 16 for scratching are formed at intervals in the axial direction, and the slits 16 for scratching are fitted with the scratching body 17, and the slits 16 for scratching are spaced apart in the axial direction. , A part of the lateral rice seed 10 is formed at a slightly narrower interval than the length of the seed pad 10 so as to always face the scratch slit 16, the slit width of the scratch pad 16 is the seed pad 10 Since it is the feeding roll of the seeding device for seedling raising box formed to have a size of 0.6 mm to 1.0 mm so as not to be stuck in the bottom, the feeding roll is a. Since it has a structure in which a large number of feeding grooves 9 are formed in parallel with the axial direction over the entire width, it can be formed most simply and inexpensively. .

(B) Since the interval of the scraping slit 16 in the axial direction is set to be slightly narrower than the length of the laterally-seeded paddy 10, the mating state as shown in FIG. Even when the grains are fit orderly one by one, a part of the seed pad 10 always faces the slit 16 for scratching, so that the scratching body 17 can surely scratch the seed.

When the slit width of the scraping slit 16 is 1.2 mm,
The sprouting seed paddy 10 is firmly fitted, and even if the scraping body 17 acts,
There is a case that it cannot be scratched out so that the toothpick can not easily remove the foreign matter that has crushed its teeth, but since the slit width of the scratching slit 16 is formed to be 0.6 mm to 1.0 mm, the seed pad 10 is a sprout paddy. Is never fitted into the slit 16 for scratching, and the scratching by the scraping body 17 is reliable.
