Problems solved by technology

For the pneumatic seed metering device, there are air pressure adjustment problems and the problem of the speed of the seed metering device, and when the air pressure is too high, it will cause the seeding tray in the seed metering device to absorb multiple seeds, and the air pressure is too small, which will cause the seed metering device to discharge The seed tray cannot absorb seeds, which seriously does not meet the agronomic requirements of related crop fields

Embodiment Construction

[0026] The present invention is a kind of seed metering device provided with an auxiliary seed clamping device, which includes a seed metering device outer shell composed of an inner fixed plate 1, an outer fixed plate 5, and a belt device 9, and a seed clamping block guide plate 2, a seed clamping Block device 3, shaft 13, seeding disc 11, seeding room partition 14, cam 10, air cutoff block 12 constitute the internal seeding device of the seed metering device, which is composed of negative pressure air pipe 7, seed box 8, transparent plate 4 1. The internal seed metering device cover plate structure of the seed metering device constituted by the outer panel 6.

[0027] Wherein, for the outer shell of the seed meter, the inner fixed plate 1 and the outer fixed plate 5 are connected by bolts in turn, and the waist belt device 9 is sandwiched between them to form an integral cylindrical outer shell. For the waist belt device 9, it is a cylindrical main body surface structure, on...

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.

Description

technical field [0001] The invention relates to a seed metering device, in particular to a mechanical seed metering device for plant seeds with medium and large particle diameters, and belongs to the field of agricultural mechanization engineering. Background technique [0002] At present, most of the seed metering devices in the prior art are completely mechanical, and some of them are combined with an air suction system. Since the weight of plant seeds is very small, the seeds will inevitably cause mechanical friction and damage in the mechanical structure. Therefore, some researchers The pneumatic system is combined with the mechanical structure as a seed meter. For the pneumatic seed metering device, there are air pressure adjustment problems and the problem of the speed of the seed metering device, and when the air pressure is too high, it will cause the seeding tray in the seed metering device to absorb multiple seeds, and the air pressure is too small, which will caus...
