Technical Field
The potato harvesting is a work which is labor-consuming, time-consuming, labor-intensive, suitable for short harvesting period and high in agronomic requirement. The tuber damage problem of the existing potato machine is serious in the harvest process, and the quality of seed potatoes and the appearance and the internal quality of commercial potatoes are reduced. Because the domestic potato variety has low crashworthiness, and the harvested potatoes have high fresh food ratio and low production and processing ratio, the commercial department puts forward high requirements on the mechanical harvest quality and storage conditions of the finished fresh-eating potatoes. Most of the existing potato diggers and combine harvesters adopt a multi-stage shaking type chain separating device to reduce the impurity rate of potatoes. In order to reduce impurity rate and improve yield, the existing harvesting machines are all provided with multi-stage cleaning and separating sieves, so that the length of the machine is increased, the machine is huge, the operation in the field is inconvenient, and the operation auxiliary time is prolonged. Therefore, the working performance of the existing potato harvester needs to be improved urgently, an auxiliary mechanism is additionally arranged, the potatoes are prevented from being damaged, and the loss rate is effectively reduced.
With the industrialization, intensification and large-scale development of potatoes, the requirements for production standardization and income high efficiency of mechanized harvesting of potatoes are higher and higher, and the number of large and medium-sized potato harvesters developed by agricultural machinery scientific research and production departments in various regions is continuously increased.

The potato digging, soil block and potato vibration separation and screening, potato grading, collecting and bagging, transporting and other operations can be completed at one time. Although the degree of mechanization is increased, there are technical difficulties that are difficult to break. The following points are mainly summarized: 1. the potato has large damage to the epidermis. The existing potato harvester basically adopts a shaking type soil-potato separating mechanism, potatoes are subjected to vertical violent vibration of a conveying chain in the whole conveying process, and the skins of the potatoes are easy to collide and damage and difficult to store; 2. the power consumption is large. The power consumption of the vertically vibrating conveying chain is about 30 to 40 percent of the total power, and the conveying chain vibrates uninterruptedly in the working process, so that the parts of the conveying chain are easily damaged, the working hours are delayed, and the service life of a machine tool is short; in order to increase the strength of parts, the high manganese steel is adopted for manufacturing, so that the manufacturing cost of the machine is increased; 3. the machines are too big in size and inconvenient to operate in the field. In order to improve the soil-potato separation effect of the machine tool, the soil-potato separation mechanism is usually designed to be lengthened or designed to be a double-layer separation mechanism, so that the length of the machine tool is prolonged, the field operation difficulty of the machine tool is increased, and the idle stroke auxiliary time is prolonged; 4. potato seedling separation is not thorough; 5. for harvesting high-yield potatoes in high ridge culture, the digging depth is increased by the digging shovel, the soil taking amount is increased, the phenomenon of soil accumulation is easy to occur at the front end of the lifting conveying chain, and a lifting conveying mechanism which has no vibration and high efficiency, is good in soil-potato separation and does not damage the skins of the potatoes in the conveying process is urgently needed to be developed.
