Description

The peanut precision sower

The utility model relates to agricultural machinery, refers to peanut seeding machinery.

At present, the small-sized peanut sower, particularly can once finish the multifunctional peanut sower of several work, kind is many, weak point is, the one, lack operation functions such as suppression after planting, whole ground, and the 2nd, the precision drilling of being unrealized, used poor formula sowing rotor and the hole formula sowing rotor inserted, do not reach the Precision Seeding requirement, have a kind of side to fill capsule kind precision drilling dish, it has the dish in a uniform hole, two circle holes are arranged, the hole has capsule to grab, and the rotation of portability peanut kind has seeds protecting plate in this dish, shell plates is arranged outward, and the peanut kind forwards the shell plates lower opening to and falls to sowing.But because of, its design clear planted angle≤103 °, the angle of charging seed 〉=235 ° cause the seed broken rate height, and kind of the hysteresis that falls makes this precision drilling dish, certainly the present of invention, reaches 14 years not by social recognition, fails to apply.

The utility model, it is imperfection at existing multifunctional peanut sower function, and side is filled the defective of capsule kind seed placing device, a kind of seed placing device that comprises after the improvement is provided, and the peanut precision sower that increases parts such as suppression, whole furrow newly, to reach the purpose of precision drilling, seeding quality height.

The utility model is so to implement, the peanut precision sower, comprise frame (1), preceding ridging plough (2), middle ridging plough (3), back earth backing plough (4), the fertilizer apparatus of frame front central authorities (5), thereafter two groups of sides are filled capsule kind formula seed placing device (7), road wheel (10), chemical spraying device (14) and all parts of film covering device (15) afterwards, behind ridging plough, establish oblique clean-up scraper (6), set up pack roller (9), and with the road wheel one, establish soil-conceying plate (13) thereafter, changing spring-tube type press mold wheel support is the spring lever formula, the clear angle of planting of side being filled capsule kind seed tray is decided to be: 103 °＜∠ AOB＜120 °, the angle of charging seed is decided to be: 220 °＜∠ AOC＜235 °.

The enforcement of such scheme is planted the angle clearly because of seed tray and is strengthened, and has avoided broken kind, and the angle of charging seed reduces, and has overcome kind of the hysteresis that falls, so improved the Precision Seeding quality effectively, this machine has increased suppression, whole furrow function again, makes multi-functional more perfect.
