Description
Technical field
The invention belongs to agricultural machinery, are a kind of seeder electronics aspirated-air type vacuum seed-distributing wheels.
Background technique
The indoor air of aspiration is extracted by high-speed fan when aspiration type sowing device works, so that air-suction chamber is formed vacuum generation negative
Pressure, when seed-sowing roller 1 turns round, absorbed seed is sowed under vacuum chamber suction function, relative to mechanical seeder, is had
The advantage that sowing is reliable, leakage sowing rate is low.Its structure is: including seed-sowing roller 1 and connector 7, the seed-sowing roller 1 is what one end blocked
Cup type body, the bottom centre of cup type body are arranged inside boss 5, connecting hole 3 are arranged in boss 5, and keyway 4 is arranged in connecting hole 3,
Single or double suction hole 2 is arranged along perimeter surface in seed-sowing roller 1, has between each row's suction hole 2 and the top surface of boss 5 certain
Distance and be uniformly arranged, be terminal pad 11 among the connector 7, one end of terminal pad 11 is hollow thin-walled cylinder
10, the other end is necking down hollow and thin-walled cylindrical body 9, and terminal pad 11, thin-walled cylinder 10 and necking down hollow and thin-walled cylindrical body 9 are connected
It is integrated, intermediate setting bleeding point 8, the cylinder outer diameter of terminal pad 11 is identical as the outer diameter of seed-sowing roller 1, end face and seed-sowing roller 1
End face seal contact, the cylinder of terminal pad 11 are used to be connected with blower along several connecting holes are arranged week, the thin-walled of terminal pad 11
10 outer diameter of cylindrical body is slightly less than or is equal to 1 internal diameter of seed-sowing roller, and semicircular notch is arranged in the oral area cylinder of thin-walled cylinder 10,
The cylinder thin-walled of thin-walled cylinder 10 is cut into the thin-walled of two kinds of length L1 and L2 with length difference, L1 is greater than L2, connection
Body 7 is placed in the oral area of seed-sowing roller 1, and the thin-walled cylinder 10 of connector 7 is located in seed-sowing roller 1, the L1 thin-walled of thin-walled cylinder 10
Positioned at the bottom of seed-sowing roller 1, L1 thin-walled end face is located among the boss 5 of seed-sowing roller 1, to shelter from the suction of 1 lower part of seed-sowing roller
Kind hole 2, L2 thin-walled are located at the top of seed-sowing roller 1, and L2 thin-walled end face is located between the suction hole 2 and end cap of seed-sowing roller 1, to reveal
The suction hole 2 on 1 top of seed-sowing roller out, is shown in Fig. 1.
The problem is that: since seed-sowing roller 1 is the cup type body that one end blocks, oral area relies on the terminal pad of connector 7
11 end faces and 1 oral area end face of seed-sowing roller formation air-suction chamber in sealing contact, contact area is big, is not only easy gas leakage and destroys air-suction chamber
