Potato screening and stacking device

Abstract

The invention provides a potato screening and stacking device. The potato screening and stacking device comprises a conveying device, a screening device and stacking devices, wherein a charge port isformed in one end of the screening device, and a plurality of discharge ports are formed in the other end of the screening device; each discharge port corresponds to one stacking device; the screeningdevice communicates with the stacking devices through the conveying device; the screening device is arranged slantwise; each stacking device comprises a support end and a stacking end; each support end is connected with the corresponding stacking end through a conveying arm; a conveying belt used for conveying potatoes is arranged on each conveying arm; each support arm is provided with a feedingport; each conveying arm is arranged on the corresponding support end in a hinged manner; each conveying arm is capable of rotating to the left and the right on the horizontal plane; and each conveying arm is capable of swinging upwards and downwards on the vertical plane. Lots of the potatoes are screened and then integrally stacked, so that the labor intensity is lowered, the manual operation is reduced, the stacking speed is increased, the production efficiency is increased, and large-scale screening and stacking for the potatoes are realized. The potato screening and stacking device is adaptive to a market need due to industrialized production.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a potato screening and stacking device. Background technique [0002] Potato is the fourth largest crop in my country, second only to wheat, rice, and corn. It is planted all over the country, and the planting area is relatively wide, and it is still increasing year by year at a rapid rate. The research of the World Potato Center shows that the demand for potatoes worldwide will increase by about 20% by 2020, and the demand for potatoes in developing countries will also be higher at that time. From the analysis of international and domestic situations, we can know that the production of potatoes Start to scale and standardize. [0003] Potato production efficiency in my country is low, and the yield per mu is only equivalent to about 40% of that in developed countries such as Europe and the United States. Potatoes are harvested mainly by hand. At present, potato...
