Potato harvester suitable for intercropping and interplanting

Abstract

The invention discloses a potato harvester which is applicable to intercropping and interplanting; the potato harvester is characterized in that a rotation axis is arranged on the upper part of the front end of a frame; the left side and the right side of the frame are respectively hinged with a front swing rod and a rear rocking rod; a power transmission wheel and a clutch are arranged on the rotation axis; a power output wheel of a hand tractor transmits the power for the rotation axis; two ends of the rotation axis are respectively provided with a crank connecting rod mechanism; the connecting rods of the two crank connecting rod mechanism are respectively hinged at the top ends of the two rocking rods; the two sides of the front end of the screen sieve are hinged at the bottom ends of the two rocking rods and the rear end of the screen sieve is suspended at the rear end of the frame; digging shovel ends are respectively fixed at the bottom ends of the two front swing rods which are hinged with the rear rocking rods by cross connecting rods so as to lead the digging shovel and the screen sieve to swing together back and forth in parallel; the optimum frequency of the back and forth swing is 35 to 50 times / min and the back and forth swing amplitude is 8 to 10cm. The application has compact structure and small volume, can be applicable to the situations of the dry, wet, soft or hard soil and the like and is applicable to harvesting the potatoes with intercropping and interplanting.

Description

technical field [0001] This application relates to agricultural implements. Background technique [0002] At present, some rural areas implement intercropping of corn and potatoes. When the potatoes are harvested, the corn trees are still growing and earring, so they cannot be harvested by large potato harvesters, but can only be harvested by farmers' manual labor. There is a great need for an agricultural machine suitable for intercropping to solve the problem of mechanized harvesting of potatoes. Contents of the invention [0003] The purpose of this application is exactly to design a kind of small-sized potato harvester suitable for intercropping. This harvester is powered by a small walking tractor. To accommodate the mechanized harvesting of potatoes between rows of corn. [0004] The structure of the present application includes a frame, a depth-gauge wheel, an excavating shovel, a separating screen, etc., and is characterized in that a rotating shaft is installed...
