Potato digger with a digging workpart of the "Paraplaw" type

Abstract

One of the reasons hindering potato farming development on Uzbekistan's farms is the low supply of inexpensive mini-production equipment for harvesting potatoes. The use of high-performance potato harvesters in small areas is uneconomical. The authors proposed a potato digger with a digging working body of the "Paraplaw" type. The study aims to develop a potato digger with working bodies of the "Paraplaw" type. A prototype of a mini potato harvester was made, and its economic tests were carried out. The basic principles and methods of classical mechanics, mathematical analysis, and statistics were used in this study. The developed digging work part is made in the form of rippers with inclined racks installed towards each other, and their chisels are equipped with ripping elements in the form of rods. The results of the digger tests have been given. It was found that during the operation of the improved potato digger, tuber losses were reduced by 2.9%, and productivity increased by 13.2% compared to the serial one.
