Description
Technical field
The utility model relates to a kind of forward type fine grain seeders, are especially suitable for the smooth rear fine grain of soil rotary tillage and broadcast
The agricultural machinery research field of kind.
Background technique
Existing mechanization fine grain seeder is usually what tractor postposition was drawn, and fine grain sows (such as rape, millet
Deng) depth of planting is required strictly, sowing is too deep to be not easy to emerge, and is sowed too shallow water deficient and is also not easy to emerge.Although having at present
The uniform technology of front and back wheel profiling ground safeguard depth of planting, but seeding machinary is post suspending, and tractor four-wheel rolls
Rut cause it is smooth after soil occur part again gentle soil density be not different, sowed again after rolling and seriously affect small seed
The sowing effect of grain.Hand-pushing fine grain sowing function overcomes disadvantages described above, but large labor intensity, low efficiency, Zhi Nengyou
It is planted for small plots such as booth vegetables.
Summary of the invention
For above-mentioned problems of the prior art and defect, the purpose of this utility model is to provide a kind of forward types
Fine grain seeder is not only able to satisfy above-mentioned requirement, and at seeding time operator it is observed that sowing situation, ensure
Seeding quality.
Technical solution adopted by the utility model to solve its technical problems is a kind of forward type fine grain seeders, including
Mainframe, slave frame, land wheel, press wheel, fore-stock, crossbeam, casing, connecting rod, oil cylinder, plants case, plough, trailing bar, chain
I, chain II, sprocket wheel I, sprocket wheel II, sprocket wheel III, the land wheel are mounted on the front end of mainframe, and the press wheel is mounted on host
The rear end of frame, the plants case and plough are separately mounted to above and below rack, after the trailing bar is mounted on plough
End；
The upper end of the mainframe is sequentially installed with fore-stock, crossbeam, casing and connecting rod, and it is dilatory that the slave frame is mounted on
The front end of machine, lifting groove, installation oil cylinder on the slave frame are machined on the slave frame, and the cylinder upper end and crossbeam are installed
It connects, is welded with pin shaft on the crossbeam, the pin sleeve on the crossbeam is in the lifting groove of slave frame；
The sprocket wheel I, sprocket wheel II are mounted on mainframe by bearing, and the sprocket wheel III is mounted on plants case by bearing
On, the sprocket wheel I is co-axially mounted with land wheel, and the sprocket wheel I is connect with sprocket wheel II by chain I, the sprocket wheel II and sprocket wheel III
It is connected by chain II；
Described sleeve pipe and crossbeam are welded by cross bar to be installed, and the small end is sleeved on casing, and the connecting rod can lead to
Overregulating screw can be adjusted up and down in height, and the connecting rod lower end is mounted on mainframe；
The above-mentioned forward type fine grain seeder can drop to ground under oil cylinder effect and realize seeding operation,
Ground can be lifted off under oil cylinder effect to stop operation and be in travel position.
A kind of working principle of forward type fine grain seeder of the utility model is:
When oil cylinder falls sowing mechanism, since the impetus of tractor drives seeder to move ahead, land wheel rotation is moved
Power is transferred to plants case through chain conveyer by land wheel, and the feed mechanism for seed rotation seeding being mounted in plants case, seed falls in plough and ditched
Slot, seed are suppressed through trailing bar covering and press wheel, complete seeding operation；When tractor turns around not needing sowing, oil cylinder makes
Sowing mechanism lifts off ground, stops seeding operation.
The utility model has the beneficial effects that the fine grain seeder of preposition installation, avoids what tractor four-wheel rolled
The sowing depth caused by rut is uneven, has ensured seeding quality, after planting rolling for tractor can also play suppression compaction；
Manpower sowing than identical sowing effect improves production efficiency, reduces labor intensity.
