Abstract

The invention relates to an anti-clogging mechanism for model holes of a vertical seed metering plate. A shoulder is machined on the inner lateral surface of each model hole of the vertical seed metering plate; a seed clearing part of a seed clearing tongue fixed on a shell is matched and assembled with a shoulder excircle and the end face of the seed metering plate to form a seed clearing mechanism, so that blocking can be cleared effectively, and seeding missing can be prevented. The structure has the function of a seed clearing mode in which a ring slot is formed along the central connecting line of each model hole in the circumferential direction of the seed metering plate and in which a tongue part is arranged in the ring slot, and has the excellent manufacturing manufacturability; and the reliability and stability of a vertical circular disc seed-metering device are improved greatly while the operating effect of the model holes on the seed metering plate is not influenced.

Description

technical field

[0001] Agricultural planting machinery and equipment, suitable for vertical disc seed metering devices. Background technique

[0002] The vertical disc seed meter occupies a relatively large price in the precision seed meter market due to its low price and good workmanship. However, due to structural limitations, it is not convenient to install a seed cleaning and anti-blocking mechanism. Since the appearance of this type of seed meter, the throwing of seeds from the hole has been achieved by its own gravity and the centrifugal force generated by the rotation of the seed disc. Once the seeds in the type hole cannot be discharged for some reason, even if the type hole is blocked and the leakage is formed, the resulting leakage phenomenon will continue and become more serious as this situation occurs in other type holes. After working for a period of time, it is necessary to disassemble the seed meter, and manually remove the blocked seeds to solve the missed ...
