Purple sweet potato combine harvester

Abstract

The invention discloses a purple sweet potato combine harvester. The purple sweet potato combine harvester comprises a frame, front wheels and rear wheels are symmetrically arranged at the left and right sides of the bottom of the frame respectively, a harvesting roller is arranged at the bottom of the front end of the frame, roll shafts at two ends of the harvesting roller are sleeved on the frame, a first driven pulley is sleeved on the roll shaft at one end of the harvesting roller, a first machine room is arranged at the top of the front end of the frame, a harvesting roller driving deviceis arranged in the first machine room, a grinding bin, a stem and leaf storage bin and a harvest bin are successively arranged in the frame, and a guiding hopper for conveying material on the harvesting roller is arranged at the bottom of the frame corresponding to the right side of the harvesting roller. According to the purple sweet potato combine harvester, the structure arrangement is smart,and the layout is reasonable; combined harvest of purple sweet potatoes is realized, purple potato stems and leaves are harvested, crushed, and recovered for storage, the purple sweet potato stems andleaves can be used as feed raw materials, and the economic benefit is high; and in addition, the harvest of the purple sweet potatoes is highly efficient, the separation efficiency of the purple sweet potatoes with soils is high, and the separation effect is good.

Description

technical field [0001] The invention relates to the technical field of agricultural production machinery and equipment, in particular to a purple potato combine harvester. Background technique [0002] Purple potato is also called black potato, and the potato flesh is purple to dark purple. In addition to the nutrients of ordinary sweet potatoes, it is also rich in selenium and anthocyanins. Purple sweet potato is one of the main raw materials of anthocyanins, which is rich in protein, starch, pectin, cellulose, amino acids, vitamins and various minerals, as well as selenium and anthocyanins. Purple sweet potato is rich in nutrients and has special health care functions. The protein and amino acids in it are easily digested and absorbed by the human body. The vitamin A rich in it can improve vision and skin mucosal epithelial cells, vitamin C can make collagen protein synthesize normally, prevent the occurrence of scurvy, and anthocyanins are natural and powerful free radi...

Problems solved by technology

[0005] However, the mechanical equipment used for purple sweet potato harvesting is rigid in structure and single in function, especially the stems and leaves cannot be recovered. In addition, the harvesting efficiency of purple sweet potato is low, and the separation effect of purple sweet potato and soil is poor.
