Abstract
The invention relates to a seeding unit provided with an auxiliary seed clamping device. Improvements are made on the conventional pneumatic seeding unit. Aiming at the problem of severe loss of local air current in a negative-pressure air chamber due to large irregular gaps of a pneumatic air-suction seeding unit acting on irregular large-diameter crop seeds and mold holes, a pneumatic seeding unit is provided with the auxiliary seed clamping device. Adsorbed single seeds can be clamped stably before falling into a seed outlet, the seeding unit adsorbs the seeds through negative pressure, the auxiliary clamping device carries and delivers seeds, and the local air current loss of the negative-pressure air chamber is reduced by reducing the working area of the negative-pressure air chamber, so that the energy loss is reduced as a whole.
