Air suction precision picking-free peanut seeding machine

Abstract

The invention relates to an air suction precision picking-free peanut seedling machine. The air suction precision picking-free peanut seedling machine comprises a pressing mechanism (1), a first soil covering plate (2), a seed-metering device (3), a second soil covering plate (4), a second rack (5), a film coating mechanism (6), a forming tie ridger (7), furrow ploughs (8), ridging ploughs (9), a first rack (10), a fan mechanism (11), a pesticide spraying mechanism (12), a fertilizer applying mechanism (13) and a seed box (14), wherein the fan mechanism is fixed in front of the first rack via a support; the ridging ploughs are arranged on two sides of the front of the first rack; the heights of the ridging ploughs are adjustable; the furrow ploughs are arranged on the first rack and are positioned on the middle rear portions of the ridging ploughs; the heights of the furrow ploughs are adjustable; the forming tie ridger is arranged at the rear of the first rack; the pesticide spraying mechanism and the fertilizer applying mechanism are fixed above the first rack; the second rack is hinged to the rear of the first rack; the film coating mechanism is transversely arranged between two sides of the lower portion of the second rack; the width of the film coating mechanism is adjustable; the seed-metering device is fixed on the second rack; the seed box is arranged above the seed-metering device; the pressing mechanism is hinged to the rear of the second rack; the height of the pressing mechanism can be changed freely; the first soil covering plate and the second soil covering plate are fixed on the second rack; and the position and the height of the first soil covering plate and the position and the height of the second soil covering plate are adjustable. The air suction precision picking-free peanut seedling machine is multifunctional; seedling depths are consistent; damage on seeds is low; manual seedling picking is avoided; and the production efficiency is high.

Description

technical field [0001] The invention relates to agricultural machinery and equipment, in particular to an air-sucking precision-quantity-free peanut seeder. Background technique [0002] Film mulching is a major feature of peanut production in my country, and it has been widely promoted in major peanut producing areas in my country. At present, most of the peanut planters developed in the domestic market are based on the sowing method of mulching after sowing. It can meet the agronomic requirements of peanut sowing, but it is time-consuming and laborious to manually break the membrane in the later stage. The traditional mechanical seed metering device is prone to different depths of sowing, resulting in uneven seedling emergence, thus affecting the improvement of peanut yield. Moreover, the traditional mechanical seed metering device has low precision and great damage to the seeds. SUMMARY OF THE INVENTION [0003] The technical problems to be solved by the present inventi...

Problems solved by technology

[0003] The technical problems to be solved by the present invention are that the existing peanut planters have low precision, great damage to the seeds, need to manually break the membrane to buckle the seedlings, and it is difficult to guarantee the quality of the seedlings
