Potato combined harvester

Abstract

The invention relates to a potato combined harvester, which is capable of effectively solving the problem of low potato harvesting efficiency. According to the technical proposal, the potato combined harvester comprises a frame, wherein the frame is composed of a main frame and an auxiliary frame which are articulated with each other; a stem cutter, a stem pick-up device and a stem feeder are sequentially mounted on the auxiliary frame; a stem crushing/throwing mechanism is mounted on the main frame of the discharge end of the stem feeder; a driving cab and a potato collecting box are mounted on the main frame; an engine and a speed changing box which are connected together are sequentially mounted on the main frame at the lower part of the driving cab; a potato-soil lifter and a cage type potato-soil separator are respectively mounted on the main frame at the lower part of the potato collecting box, respectively; a potato block lifting conveyor is mounted at the rear part of the main frame; the speed changing box is connected with the cage type potato-soil separator through a universal joint transmission shaft; the discharge end of the potato-soil lifter is connected with the feeding end of the cage type potato-soil separator; the discharge end of the cage type potato-soil separator is connected with the feeding end of the potato block lifting conveyor; and the discharge end of the potato block lifting conveyor is arranged above the mouth part of the potato collecting box. The potato combined harvester is convenient for operation so that the operation efficiency of potato harvesting is greatly improved.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to a potato combine harvester. Background technique [0002] Modern research has proved that potatoes have special effects on mediating indigestion, and are good medicine and high-quality health care products for patients with stomach problems and heart diseases. . Potatoes have a variety of beneficial effects on the human body, and are known as "the king of nutritional value" by nutritionists. For this reason, in 2008, the state listed potato as the fifth largest food crop in China and vigorously developed it. In our country, the harvesting methods of potatoes are mainly manual harvesting, so the harvesting efficiency is very low and a lot of manpower is required; although many types of potato harvesting machines have appeared on the market in recent years, due to their structural problems, they often fail to function. Single, some models need to manually cut seedlings, and some models ...
