Adjustable potato harvester

Abstract

The invention discloses an adjustable potato harvester, belongs to the field of agricultural machinery, and overcomes the defects of the prior art through hydraulic control and adjustment. The structure of the adjustable potato harvester mainly consists of a traction device, a rack, comprehensive adjusting oil cylinders, a stalk separating device, a second-stage soil-potato separating adjusting oil cylinder, a second-stage soil-potato separating and conveying device, a first-stage soil-potato separating and conveying device, a digging shovel, a digging shovel adjusting oil cylinder, a hydraulic oil tank and the like, wherein the comprehensive adjusting oil cylinders are located on the two sides of the stalk separating device; the second-stage soil-potato separating adjusting oil cylinder is located at the rear section of the rack, the fixed end of the oil cylinder is located on the oblique beam of the rack, and the movable end is connected with the two ends of a driving part of the second-stage soil-potato separating and conveying device; the digging shovel is located at the lower end of a front beam of the rack and connected with the first-stage soil-potato separating and conveying device; the digging shovel adjusting oil cylinder is located at the angle adjusting end of the digging shovel; and the hydraulic oil tank is located in front of the rack. The adjustable potato harvester is wide in application range and easy to operate, and the harvesting efficiency of the harvester and the product quality are improved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to potato harvesting machinery. [0002] technical background [0003] In the process of potato planting, the amount of labor in the harvesting process accounts for more than half of the total labor in the entire planting cycle. The level of potato mechanized harvesting technology is a key factor that directly affects the yield and quality of potatoes. [0004] Disadvantages of prior art: [0005] 1. The entry angle of the digging shovel of the existing model is fixed, which cannot adapt to different geological and soil conditions, resulting in increased digging resistance of the potato harvester in some areas and affecting the harvesting efficiency of potatoes; [0006] 2. The soil and potato separation conveyor belt of the existing model has only one stage, and the conveying angle is a fixed value. It cannot realize the coordinated adjustment of the two stages of soil and pot...
