Potato harvester matched with handle

The invention provides a potato harvester matched with a handle. The potato harvester comprises a transmission case, wherein the output of the transmission case is connected with a chain wheel box I by virtue of a transmission shaft; a guide gear in the chain wheel box I is connected with an eccentric block by virtue of a bearing; the eccentric block is connected with one end of a link shaft, and the middle of the link shaft is connected with a sleeve shaft; the sleeve shaft is fixedly connected with a transverse connecting rack; two ends of the connecting rack are respectively connected to a left side plate and a right side plate by virtue of supporting points of the connecting rack; the lower end of the connecting rack is fixedly connected with a ploughing blade; the rear lower ends of the left side plate and the right side plate are connected with supporting wheels; a conveying chain plate is positioned between the left side plate and the right side plate and is driven by a chain plate conveying main shaft; a chain wheel in the chain wheel box I is connected with one end of the chain plate conveying main shaft; the chain plate conveying main shaft is connected with a chain plate conveying secondary shaft by virtue of a conveying chain; the other end of the chain plate conveying main shaft is connected with a chain wheel box II; a chain wheel in the chain wheel box II is connected with an eccentric shaft. The potato harvester can be used for reducing the running resistance, adjusting the oil penetration angle of the ploughing blade and the depth of the supporting wheel, improving the yield and reducing the potato damage rate.
