Description

The suspended type multi-function precision sower

The utility model relates to a kind of agricultural seeder machinery, is a kind of direct-connecter planter particularly.

At present, normally used direct-connecter planter is mainly formed by hanging frame, land wheel, defeated kind of leg, plough, seed containing bucket, seeding unit and press wheel in crop seeding.But because the seeding unit of existing sower mostly is single type recess formula seed wheel sheet, be only applicable to the program request corn, and sow other crop seeding inequality, especially the defeated kind of leg that connects plough is fixed on the frame, replay brings difficulty to overline, and the waste seed, also is unsuitable for directly carrying out seeding operation on crop cover ground with returning crop stocks to the field, the scope of application is restricted, and uses inconvenience.

The purpose of the utility model provides a kind of improved suspended type multi-function precision sower, it can select program request or drilling according to the sowing crop, look soil moisture content and sow the earthing operation, and can realize directly at seeding on unfallowing field, and rational in infrastructure, applied widely, easy to install.

For achieving the above object, the solution that the utility model adopts is: the seeding unit of sower is adopted the seeding roller that is shaped on number row different size shrinkage pool groove, by the size and the requirement of sowing crop seed kind, adjust the seeding roller and make its corresponding shrinkage pool groove seeding body that is connected; The load of seeding roller is in power transmission shaft, and the variable transmission mechanism that power transmission shaft is formed by sprocket wheel and chain is connected land wheel, drives seeding unit by land wheel and rotates the realization seeding operation; Defeated kind of a leg is connected in frame by the elevation (over-and-under) type governor motion, can be according to the position of sowing defeated kind of the leg of needs adjustment, and the depth of control plough and lifting plough; And on defeated kind of leg, installed group careless mechanism additional, and dial careless mechanism and is connected land wheel with chain by bevel gear, sprocket wheel, land wheel drives and dials the rotation of careless mechanism and remove defeated weeds on the leg, the earth etc. of planting when seeding operation, guarantees the normal operation of sower.

The utility model also is equipped with adjustable covering device on the frame that is positioned at defeated kind of leg rear portion of seeding unit, can be according to the needs of soil moisture content and sowing crop, and assembling press wheel or circle blade, the earthing operation of sowing.

Because seeding unit of the present utility model has adopted the seeding roller that is shaped on number row different size shrinkage pool, power transmission shaft connects land wheel by the speed changing type transmission mechanism, and defeated kind of leg has adopted bindiny mechanism that can lift adjustment and installed group careless mechanism additional, and adjustable covering device is housed.It can select corresponding program request or drilling according to requirement of seeding, and can regulate row, spacing in the rows and seeding quantity arbitrarily, improved seeding accuracy effectively, the scope of application that enlarges, save seed, and can be directly in crop cover ground and sowing with returning crop stocks to the field, can also look soil moisture content and finish the earthing operation, its novel structure, reasonable in design, have multi-functional, seeding quality is high, easy to install, applied widely, can be used for the sowing of crops such as corn, soybean, Chinese sorghum, wheat, sesame, millet, is a kind of novel agricultural seeder machinery.
