Description
Technical field
The utility model relates to corn drill, particularly a kind of front and back changeable covering device of corn drill.
Background technology
Corn is one of the cereal crops the most widely that distribute in the world, and corn is very large at the sowing area of China, distributes also very wide, is one of main food of north of China and Southwest Mountainous Areas and other winterbourne area people.
Corn drill after planting will carry out earthing to soil.In order to coordinate corn drill at earthing automatically after planting, so covering device need to be set on sower.
Summary of the invention
The utility model provides a kind of front and back changeable covering device especially in order to make corn drill at earthing voluntarily after planting.
In order to address the above problem, the technical scheme that the utility model is taked is: a kind of front and back changeable covering device, comprise link, Connection Block I, earthing bar, connecting rod and disk coverer, the link upside is provided with Connection Block I, Connection Block is by the hinged earthing bar of bearing pin, earthing bar one end is connected with connecting rod, connecting rod lower end welding disk coverer.
Described, link one side is welded with iron plate, and iron plate is provided with bolt hole II, and earthing bar upside is provided with bolt hole IV, and bolt hole II and bolt hole IV aperture are overlapping, and the centre is equipped with bolt.
Described, the link upside is provided with Connection Block II.
Described, the link upside is provided with bolt hole I, and earthing bar upside is provided with bolt hole III.
Described, earthing bar one end welded still pipe is equipped with bolt hole on steel pipe, and bolt hole is screwed with bolt II, and the steel pipe inner sleeve has connecting rod.
During work, the earthing bar both can be connected with Connection Block I, also can be connected with Connection Block II.When the earthing bar was connected with Connection Block I, the bolt hole IV of earthing bar upside and the bolt hole II aperture on iron plate were overlapping, fix with bolt.When the earthing bar was connected with Connection Block II, the bolt hole III of earthing bar upside and the bolt hole I aperture on support were overlapping, fix with bolt.
The rotation that connecting rod in the utility model is can be in steel pipe random, the angle that is used for regulating disk coverer, when sower advances, because the angle of disk coverer and land wheel is adjustable, thus the soil amount of control earthing.
The beneficial effects of the utility model are: Connection Block I and Connection Block II have been installed respectively, so the position of earthing bar is adjustable on link; The rotation that connecting rod is can be in steel pipe random is so the soil amount of earthing can accurately be controlled.
