Abstract

PURPOSE:To enable the sure fitting of seeds into seed-sucking openings without missing the fitting by disposing the first and second stirring brushes to a seed- feeding section and allowing the top ends of the sparsely formed fillings of the brushes to abut on the seed-sucking openings. CONSTITUTION:The first stirring brush 52 and the second stirring brush 57 are disposed in a seed-feeding section at an interval in the rotation direction of a sowing roll and the top ends of the sparsely formed fillings of the brushes are abutted on seed-sucking openings 8. Since the seeds are thereby always moved between the spaces of the brushes in the direction of the arrow and the seed-sucking openings 8 are rotated for a long distance in a state of the existence of the seeds, the time for fitting the seeds into the openings is elongated to surely fit. Since the top ends of the first and second fillings 65 and 66 are also abutted on the seed-sucking openings 8, respectively, the seed-sucking openings 8 are brushed twice to remove the excess seeds.

In addition, the mounting plate 12-
When the number of Huns seeds decreases, no other seeds will fit into the seed suction holes 8 after being scraped out by the first stirring brush 56, so the seeds swept back by the rotating brush blades will pass through the gap and pass through the mounting plate. The seeds always move between the gaps between the bristles 65 as shown by the arrow A, and the seed suction holes 8 rotate for a long distance with the seeds present, so that the time for the seeds to fit is fixed. It becomes long to ensure a secure fit.

A lower rubber roll 20 and a side rubber roll 24 that are in close contact with the outer peripheral surface of the central shaft cylinder 18 are provided below and on the sides of the central axis f$18, the lower rubber roll 20, the side rubber roll 24, and the roll part 7. The seeding roll 6
A blowing chamber 17 is formed as an enclosed space on the upward rotation side of the roll section 7 from the seed falling section 14 to the seed supply section 13, and includes the central shaft tube 18, the lower rubber roll 20, and the side comb rolls 24. Close contact 19 and close contact 2 with roll part 7
The suction chamber 16 is created by a space other than the blowing chamber 17 surrounded by the downward rotation side of the roll section 7 from the seed supply section 13 to the seed drop section 14 in the sowing roll 6 due to the close contact section n and the close contact section 3. is formed, and seed suction holes 8 having communication ports 11 communicating with the inside of the roll part 7 are formed on the outer circumferential surface of the roll part 7 of the seeding roll 6. , the seeds reach the seed supply section 13 from the seed supply port 4 of the supply hopper 1, and are sucked into the seed suction holes 8 of the roll section 7 of the rotating seeding roll 6 in the seed supply section 13 and fit therein.

Thus, a seed supply section 13 is formed by the leakage brush 55 on the lower surface of the tip edge of the mounting plate l and the outer peripheral surface of the seeding roll 6. Since the brushes 57 are arranged in two rows, even if there are seeds that do not fit on the inclined surface 9 of the seed suction hole 8 due to a bridging phenomenon, they can be removed by the first stirring brush 56 and the second stirring brush 57. The seed suction hole 8 sucks other seeds.

In addition, the 11th fi stirring brush section and the second stirring brush 57 are
Both are formed by sparsely planting the bristles on the brush mounting plate 64 with a gap μs that is approximately the same as the spacing between the seed adsorption holes 8, so that the seeds that rotate together with the sowing roll 6 that rotates five times will pass through the gaps. The seeds passed through to the vicinity of the second stirring brush 57 and swept back by the rotary brush father return to the mounting plate 12 side through the gap μs, so that the seeds are evenly distributed in the seed supply section 13. Therefore, the first stirring brush and the second
When the agitation brush 57 scrapes out the seeds that have caused the blistering phenomenon, other seeds can be immediately sucked into the seed suction holes 8. That is, the seeds always move between the gaps between the bristles 65 as shown by arrow A, and the seed suction hole 8 rotates for a long distance with the seeds present, which increases the time it takes for the seeds to fit together and ensures that they fit securely. let

When the seed suction hole 8 passes through the part of the lower rubber roll of the seed falling part 14 that is in close contact with the inner circumferential surface 21 of the roll part 7,
The suction from the communication port 11 of the seed suction hole 8 is released, and since the seed faces the air outlet 17, the seed is pushed out by the positive pressure of the air outlet 17, and then the air outlet of the air blowing nozzle (equipment) However, in the present invention, since the seeds are rubbed by the first raking brush 53 before receiving the blown air from the air outlet 61, even seeds that are tightly fitted can be blown out to some extent. Since the mixture is weakened, some of the seeds fall into the seed falling part 14 due to the blowing air.

(Effects) The present invention provides a seed supply section Bt on the outer periphery on the upward rotation side of the horizontally rotating seeding roll 6 in which seed suction holes 8 are arranged in parallel at predetermined intervals on the circumferential surface. A suction-type seeding device is provided with a seed dropping section 14 on the outer periphery of each, and a suction chamber 16 for adsorbing seeds from the seed supply section 13 and a blowing chamber 17 for blowing out the adsorbed seeds are formed inside the sowing roll 6. In the seed supply unit 13, a first I
f The stirring brush ring and the second stirring brush 57 are provided at intervals in the rotational direction of the seeding roll, and the bristles of the brushes are sparsely formed, and the tips of the bristles face the seed suction holes 8. Since this is a type seeding device, (1) the first stirring brush I and the second stirring brush 57 are provided at intervals in the rotational direction of the seeding roll, and the bristles of the brushes are formed sparsely, so that seeds L and Always move between the brushes in the direction of arrow A. Therefore, since the seed suction hole 8 rotates for a long distance while the seeds are present, the distance between the seeds to be fitted becomes long, and the seeds are surely fitted.
