Description

An automatic centering pneumatic corer for fresh lotus seeds

technical field

The invention relates to the technical field of crop coring and nuclear removal equipment, in particular to an automatic centering pneumatic coring machine for fresh lotus seeds.

Background technique

With the continuous improvement of people's living standards, high-quality white lotus with core is more and more popular, but high-quality white lotus with core still needs to be prepared through tedious processing procedures such as peeling, peeling, and core; although At present, there are many kinds of lotus seed automatic processing equipment in the market, but the processing of white lotus is still mainly manual. Usually, a hand-operated lotus seed sheller is used to first cut the shell and then remove the shell, and then remove the shell attached to the lotus seed surface by hand. A layer of seed coat, and finally use a steel needle to poke the core, which not only has extremely low work efficiency, but also has high labor intensity, high loss rate, and unstable product quality. And for the peeling and peeling process of fresh lotus seeds, some models have also appeared on the market, such as "a kind of lotus seed peeling and peeling integrated machine" disclosed by patent CN201110241904. Skin, but can not complete the core process of fresh lotus seeds. A machine for lotus seeds, such as "a lotus seed coring machine that can adapt to the size of lotus seeds" disclosed in Chinese patent CN201310034388. The pressure of the lotus seeds is too high, and the loss of the car drilling method is large, so it is not suitable for the operation of fresh lotus seeds, and the drill bit of the self-adaptive device is driven by the pressure wheel to follow the size change of the lotus seeds and automatically rises and falls.

Contents of the invention

The technical problem solved by the present invention is to provide an automatic centering pneumatic corer for fresh lotus seeds to solve the above-mentioned shortcomings in the background technology.

The technical problem solved by the present invention adopts following technical scheme to realize:
