Potato harvester

Abstract

The invention discloses a potato harvester. The potato harvester comprises a first machine frame and a second machine frame, a bottom beam is fixedly arranged on the inner side of the bottom of the first machine frame, a plurality of plough shovel assemblies with the adjustable positions sleeve the bottom beam, machine wheels are rotationally installed on the two sides of the first machine frame, and vibration transmission assemblies are fixedly installed at the two ends of the bottom beam; vibration separation assemblies are movably connected with the power output ends of the vibration transmission assemblies; a conveying device is arranged on the side, close to the first machine frame, of the second machine frame, a plurality of evenly-distributed strip-shaped material grooves are formed in the conveying device, an obliquely-arranged material gathering groove is formed in the lower part of the side, away from the first machine frame, of the top end of the conveying device, and a spiral material screening assembly which is rotationally installed on the second machine frame and is in transmission connection with the conveying device is arranged below the discharging end of the material gathering groove. The potato harvester is simple in structure, a grading type separation mode is adopted, potato mechanical continuous harvesting is achieved, meanwhile, soil smashing and ploughing can be achieved, and potato picking and later crop planting are facilitated.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a potato harvester. Background technique [0002] Potato is one of the important economic crops in my country. Because potatoes grow under soil and have tubers, there are many difficulties in harvesting them. Traditional harvesting methods are not only inefficient, but also unable to guarantee quality and yield. This limits the development of potatoes to a certain extent. The potato harvester uses small tractors popular in rural areas as the power source. Dig out the potatoes and pick them up manually, which can ensure a certain production capacity and efficiency. [0003] Existing potato harvesters on the market generally do not have screening devices for soil and potatoes, and only rely on the gaps on the lifting chain to leak the soil. When the soil humidity is high, the soil shoveled together with the potatoes will form lumps, and the lumps of soil will not be easily...

AI Technical Summary

Problems solved by technology

When the soil humidity is high, the soil shoveled together with the potatoes will form lumps, and the lumps of soil will not be easily separated from the potatoes; a certain amount of soil will also be wrapped on the surface of the potatoes, and it is difficult to rely solely on the vibration of the lifting chain. Shake off the soil adhering to the surface of the potato; and because the potato is usually an irregular ellipsoid, it is not easy to roll during the transportation process, and the separation effect of the soil on one side is not very good if a single vibration separation method is used. And the pointed end of the potato is easy to get stuck in the gap, causing serious damage to the skin and affecting the subsequent harvest
