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 can sow seeds in a large number (for example, lo per hour).

It is not possible to sow seeds in a nursery box with 0 seedlings.If you try to increase efficiency, you will not be able to level the seeds completely.

Therefore, we came up with the idea of leveling in two stages instead of one stage, and when we created a structure that could be leveled in two stages, we found that it was more effective than expected.

However, when leveling in two stages, the first stage is rough work, so the second stage will be over-supplied.

This project solves this problem of oversupply of seeds.

(Means for Solving the Problem) Therefore, the present invention forms seed supply parts* at m positions in the E direction of the horizontal shaft delivery roll 8, which has a large number of delivery recesses 9 formed on the outer peripheral surface, and A second rotary leveling brush 19 is provided at a position substantially above 8, and a first rotary leveling brush 18 is provided between the seed supply section 38 and the second rotary leveling brush 19 to level the seeds in two stages. A grain flow board 2 of the seed rice supply hopper 1 is provided above the first rotating leveling brush 18, and a gap communicating with the seed supply section 38 is provided between the first rotary leveling brush 18 and the grain flow board 2. η, and excess seeds blown away by the rotation of the second rotary leveling brush 19 are returned to the seed supply blade through the gap n. .

(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 a funnel 4 is formed by providing an inverted grain flow plate 2.3 at the lower part of the seed rice supply hopper 1. 5 is a supply port provided at the bottom of the funnel 4; 6 is the seed supply hopper 1;

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 shaft 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. Form. The feeding recess 9 is formed to have a width that allows the seed rice 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 one rotation 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 an arc shape.

Therefore, the horizontal axis feeding roll 8 is formed as a large diameter roll of 220 mm or more, and the 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. Make sure they fit together.

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 6.

A second rotary leveling brush chamber 9 is provided at a position substantially above the horizontal feed roll 8, and is located between the second rotary leveling brush 19 and the seed supply section 38 formed below the supply port 5. A first rotary leveling brush 18 is provided to level the excess seed rice 10 co-rotating with the horizontal axis feed-out roll 8 over two stages.

That is, both the first rotating leveling brush 1B 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 rotating leveling brush 19 also has the function of taking out the young bamboo seeds 20.

The first rotating leveling brush 18 is formed to have a smaller diameter than the second rotating leveling brush 19, has a gap η between it and the lower surface of the grain board 2, and has its rotating shaft 21 aligned with the seeding device. Attach by pivoting to the side plate n.

The gap η is formed in communication with the seed supply section 38,
The seed rice 10 swept away by the second rotating leveling brush 19 jumps over the first rotating leveling brush 18 and returns to the seed supply section.

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

This is the paddy receiving box containing the four penance seeds taken out by the rotating forward side 11.

A seed rice guiding cover n is provided on the side surface of the horizontal shaft feeding roll 8.
The function is to guide the material from the upper position to the lower position so as not to damage it.

The sponge layer provided inside is brought into contact with the outer circumferential surface of the horizontal axis feeding roll 8.

28 is the horizontal axis feeding roll 8 and the 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; 31 is a scraper provided below the lower end of the grain board 3;
Seed rice l with the tip close to the outer circumferential surface of the roll 8 for the edge of the horizontal axis.
Prevent O from falling. Reference numeral 32 denotes a horizontal transfer table having transfer rolls 34 for transferring the seedling raising boxes, and mushrooms refer to partition plates 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.

Seed rice in the seed supply hopper L! 0, adjust the supply amount adjustment plate 6 at the lower end of the grain flow board 2 and the flow grain board 3 to the desired position,
When the horizontal axis feed roll 8, the first rotary leveling brush 18, and the second rotary leveling brush 19 are rotated and the seedling raising box is transferred by the horizontal transfer blade, the seed rice that has flowed down on the grain plate 3 of the funnel 4 is 10 fits into the feeding recess 9.

In this case, the feeding recess 9 is on the rotation forward side 1 when viewed from the side.
1 has its corner portion cut out to form an inclined surface, and the rotating backward side 13 is formed as an upright wall 15 having a corner portion 14, so that the seed rice 10 is raised by the rotation of the horizontal axis feed-out roll 8. The sloping surface 12 of the recess 9 allows the recess 9 to smoothly slide into the feeding recess 9, and the upright wall 15 abuts against the seed rice 10 to raise the seed rice 10.

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 section 38 below the supply port 5. A leveling brush 18 is provided, and 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. , most of the excess seed rice 10 co-rotating with the horizontal axis feed-out roll 8 is swept back by the first rotating leveling brush 18, and the excess seed rice 10 that is not fitted into the feeding recess 9 that has passed below the first rotating leveling brush 18 is swept back. The seed rice 10 is surely leveled and swept back by a second rotating leveling brush 19.

Thus, the first rotating leveling brush 18 has a gap η communicating with the seed supply section 38 between the lower surface of the grain board 2 and the lower surface of the grain board 2.
Therefore, the excess seed rice 10 swept back by the second rotating leveling brush 19 passes through the gap η and jumps over the first rotating leveling brush 18 to the seed supply section 38.
Therefore, the surplus rice grains 10 between the first rotating leveling brush 18 and the second rotating leveling brush 19 are reduced and are leveled by the second rotating leveling brush 19 so as not to accumulate more than necessary. , it fits securely into the feeding recess 9.

Further, the ascetic seed rice 20 is caught by the tip of the second rotary leveling brush 19, raised, and taken out to the rice receiving box π.

Thus, the seed rice 10 fitted into the feeding recess 9 passes below the second rotating leveling brush 19, is guided downward by the sponge 2B of the seed guidance cover n without spilling, and falls downward at the lowest point. Then, the seeds are sown in the seedling nursery box n.

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

(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, 1000 seedlings per hour).If you try to increase efficiency, it is impossible to completely level the seedlings. be.

Therefore, we came up with the idea of leveling in two stages instead of one stage, and when we created a structure that could be leveled in two stages, we found that it was more effective than expected.

However, when leveling in two stages, the first stage is rough work, so the second stage will be over-supplied.

However, in the present invention, a seed supply section 38 is formed 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 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 38 and the second rotary leveling brush 19 to perform leveling in two stages. is provided with a seed supply hop and a grain board 2 with par 1, a gap η communicating with the seed supply section is provided between the first rotating leveling brush 18 and the grain board 2, and the second rotating Leveling brush 19
Since this is a seeding device for a high-speed seedling box seeding plant in which the excess seeds blown away by the rotation are returned to the seed supply section through the gap n, the horizontal axis feed-out roll 8 is rotated at high speed. Even if the second rotary leveling brush 19 rotates, the excess seeds are blown away, and the seeds are returned to the seed supply blade through the gap η, so that the first rotary leveling brush 18 and the second rotary leveling brush 19 are connected to each other. Excess rice seed lO between the flat brush 19
By not storing more than necessary and reliably fitting into the feeding recess 9, it is possible to expect a high-speed seeding effect.
