Seeding hopper is equipped with below plate, seeding feed hopper bottom is drawn and extended downwardly by round plants case end plate, in the seeding hopper
Equipped with multiple front and backs arrange and with the one-to-one seeding pipeline in multi-turn kind hole,
Further preferably, described kind of hole inner wide and outer narrow improves the stability for being adsorbed on seed at kind of hole, prevents seed shedding
Kind hole.
Further preferably, it is located at kind of hole in inner wall of rotary drum and is equipped with kind of a spoon, the spoon mouth for planting spoon is directed toward and rollers roll direction
Unanimously, it is suitable for the biggish seed of particle.
Further preferably, shaft is equipped at the center of drum front end face, the shaft is pierced by by plants case rear end face.
Further preferably, it is terminated with seeding connector in seeding hopper bottom, is equipped with and the seeding pipeline one in seeding connector
One corresponding sowing port, convenient for seed is discharged into corresponding furrow.
The beneficial effects of the utility model are:
Since the roller of the circle and rear end opening that are arranged in round plants case, circumferential direction are uniformly distributed in roll circumference side wall
Kind hole, the circumferential inner wall of roller gives the cross component force supported upwards to the seed being adsorbed at kind of hole, prevents from turning in roller
During dynamic, the seed at kind of hole is adsorbed on because self gravity falls off, and prevents broadcast leakage phenomenon from occurring.
Due to the roller of tubular design, the kind hole that multi-turn is arranged circumferentially can be produced on roll circumference side wall, and
Be equipped in seeding hopper multiple front and backs arrange and with the one-to-one seeding pipeline in multi-turn kind hole, make to turn over and be located above
The seed fallen after baffle enters corresponding seeding pipeline, and eventually falls in the furrow that lower section is ploughed, and realizes multirow seeding, improves
Seeding efficiency.
