Abstract

The utility model discloses a pneumatic chain drive forced seeding precise hill seeder, wherein a hill seeder support is provided with a frame supported by symmetrical stand columns; the discharge opening of a seed case arranged on the frame is fixed with a seed guide disk; a seed sucking disk, which is driven by a driven chain wheel, is positioned between the seed guide disk and a negative pressure air chamber and is matched with the seed guide disk and the negative pressure air chamber; moreover, the seed sucking disk is provided with a hole seeding rolling drum through a hill seeder shaft; a wheel hub of the hole seeding rolling drum is provided with zigzag-type seed conveying tubes which are in radial even distribution and have seed receiving ports and seed discharging ports as well as seed guide tubes matched with the seed drop points of the seed guide disk; the outlets of the seed guide tubes are corresponding to the seed receiving ports of the zigzag-type seed conveying tubes; the seed discharging ports of the zigzag-type seed conveying tubes are connected with the indenting devices respectively arranged on the seed outlet ports evenly distributed on the hole seeding rolling drum; a cam fixed on the hill seeder shaft is matched with the punching claws of the indenting devices controlled by springs; moreover, a driving chain wheel arranged on the hill seeder shaft drives the seed sucking disk to rotate through the chain drive driven chain wheel. The hill seeder, which realizes synchronous rotation of the seed sucking disk and the hill seeder, does not have strict requirements on soil, thereby obtaining strong adaptability.

Description

The seeding precision drill is forced in air-sucking type chain drive

Technical field

The utility model belongs to the improvement of sower dibbler, and particularly the seeding precision drill is forced in air-sucking type chain drive.

Background technology

At present, use more a kind of precision drill to be the presser type precision drill, its structure is to utilize that the negative-pressure air-flow essence is measured kind, seeding, and its dispenser is the external variable transmission mechanism, and fixedly indenting tool and pressing plate indenting tool are being set on the uniform through hole of dibbler rolling element endless belt.This dibbler complex structure, seeds sucker and dibbler rotate asynchronous, to the character of soil, whole require height, bad adaptability, this has just influenced applying of precision drill.

Summary of the invention

The purpose of this utility model is to provide a kind of air-sucking type chain drive to force the seeding precision drill, and seeds sucker and dibbler are rotated synchronously, less demanding to soil, and adaptability is strong.

The utility model is achieved in that a kind of air-sucking type chain drive pressure seeding precision drill, comprise by the dibbler frame and be installed with and lead kind of a dish, seeds sucker that negative pressure chamber matches and sowing rotary drum, frame by symmetrical upright supports is being set on the dibbler frame, the kind case of on frame, installing, installing on its discharging opening and leading kind of a dish, seeds sucker by the driven sprocket transmission is being led between kind of dish and the negative pressure chamber, and with lead kind of dish and negative pressure chamber and match, on the dibbler frame, the bunch planting cylinder is installed by the dibbler axle, on the wheel hub of bunch planting cylinder, be provided with and be radial uniform Zigzag type grain tube with inoculation mouth and sowing port, with lead kind of dish kind of the grain conductor that point matches that falls, its outlet is corresponding with the inoculation mouth of Zigzag type grain tube, the cavitation device of installing respectively on kind of the mouth that goes out that the sowing port of Zigzag type grain tube and bunch planting cylinder are uniform is connected, the cam that installs on the dibbler axle matches with the spring controlled pawl that burrows of cavitation device,, the drive sprocket of installing at the dibbler axle drives the seeds sucker rotation by the chain drive driven sprocket.

The utility model dibbler rolls when sowing in the ground, and the air entry that is located at negative pressure chamber is connected with the negative pressure source of the gas, makes to produce negative pressure in the negative pressure chamber, and the seed of planting case output is attracted to by on the suction hole of dibbler axle by the seeds sucker of chain drive rotation.Because under the effect of leading kind of dish, when seeds sucker forwards predetermined angular to, the air admission hole that is provided with communicates with a suction hole of seeds sucker, it is the absorption affinity that seed loses negative pressure, seed just falls in the bunch planting cylinder in the Zigzag type grain tube of one of them by grain conductor, when this Zigzag type grain tube changes downwards along with the bunch planting cylinder, seed in the Zigzag type grain tube backflows to move in the grain tube invagination and enters in the corresponding cavitation device from sowing port, when cam made its spring controlled pawl that burrows of cavitation device that buries be in deployed position by force, seed just entered in the kind cave of soil smoothly.When the pawl that burrows leaves the soil species cave,, thereby realize forcing precision drilling because the effect of return spring makes the pawl closure that burrows.

Dibbler axle of the present utility model rotates seeds sucker and dibbler by chain drive synchronously, and the spring controlled pawl that burrows of cam control cavitation device is forced to open when burying cavitation and realizes sowing in the cave.Therefore less demanding to soil, adaptability is strong, and the scope of application is wide.
