Cassava puller clamping and pulling device

Abstract

The invention relates to a clamping and pulling device, and specially relates to a cassava puller clamping and pulling device comprising a spring, an upper sphere, a lower sphere, an upper sphere seat, a lower sphere seat, a screw rod, double-end studs, an upper clamp bolt and a lower clamp bolt; the upper sphere is spherically hinged to the upper sphere seat; the lower sphere is spherically hinged to the lower sphere seat; the upper and lower spheres are threaded with the screw rod; the upper clamp bolt is threaded with the upper sphere seat; the lower clamp bolt is threaded with the lower sphere seat; the upper and lower sphere seats are fixed by the spring arranged between said two. The cassava puller clamping and pulling device ensures the cassava and a cassava clamp to be mutually parallel, so the pulling force can providing the maximum component force in the stem direction, thus reducing bearing force on the cassava puller, and reducing cassava damages and fractures.

Problems solved by technology

[0002] At present, my country has not realized the mechanized harvesting of cassava, which has a negative impact on the development of cassava industry.

However, the disordered growth of cassava stalks and tubers and the fact that cassava mainly relies on manual planting and the mechanized harvesting of cassava have increased the difficulty of mechanical harvesting of cassava.

In addition, the harvest season of cassava is too concentrated, mostly from October to January of the next year, and the roots of cassava are brittle and easy to break and difficult to store

At present, domestic cassava harvesting machinery is in the experimental research stage, there is no mature model, and the harvesting machinery has a low harvest rate; abroad, although a cassava root harvesting machinery suitable for local use has been developed, it is suitable for sticky soil and the growth of cassava in my country. The situation has not been reported, and the cassava harvesting machinery developed abroad is not suitable for our country

According to the planting characteristics and biological characteristics of cassava, the mechanism of mechanical harvesting of cassava tubers is complicated, and there are many factors affecting the quality of operation. The cassava pulled up by the existing cassava uprooting mechanism has great damage and more soil containing impurities.
