Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a seeding device for a high-speed seedling box seeding plant.

(Prior art) Conventionally, a seed supply section was formed at a position above one side of a horizontal shaft feeding roll having a large number of feeding recesses formed on the outer peripheral surface, and a rotating leveling brush was provided at a position substantially above the horizontal shaft feeding roll. is publicly known.

(Problems to be solved by the invention) The above-mentioned known method can sow seeds in a small number of seedling boxes, but cannot sow seeds in a large number of seedling boxes (for example, 1,000 seedling boxes per hour).It is necessary to improve efficiency. In this case, it is not possible to achieve perfect balance.

Therefore, I came up with the idea of leveling the rice in two stages instead of one, and when I added lacquer to the second stage, the effect was better than I expected.

(Means for Solving the Problem) Therefore, the present invention forms a seed supply section 3 at an upper position on one side of the horizontal axis feeding roll 8 which has a large number of feeding recesses 9 formed on the outer peripheral surface, and A second rotary leveling brush 19 is provided at a position substantially above the seed feed section blade 8, and a first rotary leveling brush 18 is provided between the seed supply blade and the second rotary leveling brush 19 to level the seeds in two stages. This is a seeding device for a high-speed seedling box seeding plant.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a seed rice supply hopper, and at the bottom of the seed rice supply hopper 1 there is a rectangular grain board. , 3 to form a funnel 4. 5 is a supply port provided at the bottom of the funnel 4; 6 is the seed supply hopper 1;
This is the supply amount adjustment plate of the supply amount adjustment device 7 attached to the.

The grain grain plates 2.3 are formed such that one grain grain plate 2 is short and the other grain grain plate 3 is long, so that the lower end of the grain grain plate 3 is brought close to the outer peripheral surface of the horizontal axis feed roll 8.

The horizontal axis feed roll 8 is provided below the short grain grain board 2. On the outer peripheral surface of the horizontal axis feeding roll 8, feeding recesses 9 in the form of horizontal grooves parallel to the generatrix direction are formed around the entire circumference at desired intervals. In this embodiment, approximately 90 feeding recesses 9 are formed. The feeding recess 9 is formed to have a width that allows the seeds 10 to fit in one horizontal row.

Therefore, when viewed from the side, the feeding recess 9 is located on the forward rotation side 1.
1 has its corner portion cut out to form an inclined surface 12, and the rotational backward movement side 13 is formed into an upright wall 15 having a corner portion 14. The inclined surface 12 is formed into an inclined surface that becomes lower from the forward rotation side 11 to the backward rotation side 13. In this embodiment, the inclined surface 12 is horizontally inclined, but it may be inclined in a conical shape.

Therefore, the horizontal axis feeding roll 8 is formed into a large diameter roll of 220 mm or more, and its outer peripheral surface is formed into an arcuate surface as close to a planar shape as possible, so that the seed rice 10 is reliably fed into the feeding recess 9. so that it fits.

Further, slits 16 are provided on the outer peripheral surface of the horizontal shaft feed roll 8 at desired intervals in the left-right direction, all around the circumference. slit 1
The depth of the slots 6 is the same as or slightly deeper than the recess 9, and a knife 17 is fitted into each slit 16.

Therefore, a second rotary leveling brush 19 is provided at a position approximately on the side of the horizontal axis feed roll 8, and the second rotary leveling brush 19 and the seed supply section 3B formed below the supply port 5 are connected to each other. A third rotary leveling brush 18 is provided between the horizontal shaft feeding rolls 8 and 8.
The seed rice 10 that rotates together with the rice grains is leveled over two stages.

That is, both the first rotating leveling brush 18 and the second rotating leveling brush 19 rotate in the opposite direction to the horizontal axis feeding roll 8 at the contact surface of the horizontal axis feeding roll 8.
The second rotary leveling brush 19 also has the function of taking out the grains that have been left untreated.

The first rotary leveling brush 18 is formed to have a smaller diameter than the second rotary leveling brush 19, and there is a gap η below the grain flow plate 2.
The rotating shaft 21 is attached to the side plate n of the seeding device.

The gap η allows the rice seeds lO swept back by the second rotating leveling brush 19 to jump over the first rotating leveling brush 18 and return to the side of the seed supply section.

The central axis 24 of the second rotary leveling brush 19 is connected to the arm 3.
5, and the base of the arm 35 is rotatably attached to a horizontal shaft that is pivoted to the side plate A. A height adjustment device for adjusting the height of the second rotary leveling brush 19 is provided at the tip of the arm.

Reference numeral 26 denotes a box for receiving unused paddy from the ascetic seeds taken out by the rotating forward side 11.

A seed paddy guiding cover 27 is provided on the side surface of the horizontal shaft feeding roll 8. The zero type paddy guiding cover n is used to guide the seed paddy l fitted into the feeding recess 9.
The sponge 2B provided inside is brought into contact with the outer circumferential surface of the horizontal shaft delivery roll 8, which functions to guide the O from the upper position to the lower position without damaging it.

28 is the horizontal axis feeding roll 8. First rotating leveling brush 18
, a motor for driving the second rotating leveling brush 19, 30
31 is an adjustment knob for adjusting the rotation of the motor 28, and 31 is a scraper provided below the lower end of the grain flow plate 3, whose tip is brought close to the outer circumferential surface of the horizontal axis feed roll 8 to prevent the rice seed lO from falling. To prevent. 32 is a horizontal transfer table having transfer rolls 34 for transferring the seedling box wings, and 37 is a partition plate provided on both left and right sides of the horizontal axis feed-out roll 8.

Note that a paddy guide that moves up and down by a parallel link may be provided below the horizontal axis feed-out roll 8, and in this case, vertical rows of paddy can be sown in the seedling raising box.

(effect) Next, we will discuss the effect.

Put the seed rice 10 into the seed rice supply hopper 1, adjust the supply amount adjustment plate 6 at the lower end of the grain flow plate 2 and the flow grain board 3 to the desired position,
When the horizontal shaft feeding roll 8, the first rotary leveling brush 18, and the second rotary leveling brush 19 were rotated, and the seedling box blades were transferred by the horizontal transfer stage, they flowed down on the grain board 3 of the funnel 4. The rice seed lO fits into the feeding recess 9.

In this case, the feeding recess 9 is on the forward rotation side when viewed from the side!
1 has a corner cut out to form an inclined surface 4, and the rotation backward side 13 is formed as an upright wall 15 having a corner 14, so that the type 1 paddy 10 is raised by the rotation of the horizontal shaft delivery roll 8. The sloping surface 4 of the recess 9 allows the recess 9 to smoothly slide into the delivery recess 9, and the upright wall 15 abuts against the seed rice 10 to raise the seed rice 10.

Therefore, a second rotary leveling brush 19 is provided above the horizontal axis feed roll 8, and a first rotary leveling brush 19 is provided between the second rotary leveling brush 19 and the seed supply blades below the supply port 5. A leveling brush 18 is provided, the first rotating leveling brush! 8 and the second rotating leveling brush 19 are both rotating in the opposite direction to the horizontal axis feeding roll 8 at the contact surface of the horizontal axis feeding roll 8, so that the size of the seed rice lO co-rotating with the horizontal axis feeding roll 8 can be reduced. The portion is swept back by the first rotating leveling brush 18, and the seed rice 10 that has passed below the first rotating leveling brush 18 and is not fitted into the feeding recess 9 is reliably leveled by the second rotating leveling brush 19. Sweep it back.

Therefore, the first rotary leveling brush 18 is attached with a gap η below the grain board 2, and its rotating shaft 21 is attached to the side plate A of the seeding device. The seed rice lO swept back by the second rotating leveling brush 19 is
Since the rice grains 10 between the first rotary leveling brush 18 and the second rotary leveling brush 19 are reduced, they are reliably fed out. Fits into the recess 9. In addition, the ascetic seed paddy is caught by the tip of the second rotary leveling brush 19 and raised to be taken out into the paddy receiving box.

Thus, the seed rice 10 fitted into the feeding recess 9 passes below the second rotating leveling brush 19, is guided downward without spilling by the sponge layer of the seed guidance cover n, and falls downward at the lowest point. Then, the seeds are sown inside the seedling nursery box.

In the above case, since the horizontal axis feeding roll 8 is formed as a large diameter roll of 220 mm or more, the outer circumferential surface of the horizontal axis feeding roll 8 is formed into an arcuate surface as close to a planar shape as possible. . Therefore, even if the horizontal axis feeding roll 8 is rotated at high speed,
The seed rice 10 is reliably fitted into the feeding recess 9, and a large number of seedling boxes 33 can be sown in a time period of a, without reducing the sowing accuracy.

(Effects) Conventionally, a seed supply section was formed above one side of a horizontal shaft feeding roll with a large number of feeding recesses formed on the outer peripheral surface, and a rotating leveling brush was provided at a position substantially above the horizontal shaft feeding roll. It is publicly known.

The above-mentioned known method can sow seeds in a small number of seedling boxes, but cannot sow seeds in a large number of seedling boxes (for example, 1,000 seedlings per hour).If you try to increase efficiency, you cannot completely level the seedlings. be.

Therefore, I came up with the idea of leveling the rice in two stages instead of one, and when I added lacquer to the second stage, the effect was better than I expected.

However, in the present invention, a seed supply section (is formed at a position above one side of the horizontal axis feeding roll 8 having a large number of feeding recesses 9 formed on the outer peripheral surface thereof, and a second rotation equalizer is formed at a position substantially above the horizontal axis feeding roll 8. A flat brush 19 is provided, and a first rotary leveling brush 18 is provided between the seed supply section* and the second rotary leveling brush 19 to provide a seeding device for a high-speed seedling box sowing plant that leveling is done in two stages. Therefore, even if the horizontal shaft feed-out roll 8 is rotated as fast as possible to sow seeds into too many seedling boxes per hour, it still functions sufficiently and can achieve the purpose.
