Background

Radish is an important root vegetable in China, and has the characteristics of multiple varieties, high yield and strong adaptability. However, in China, radish planting is mainly carried out by individual households at present, the land is relatively dispersed, the production mode still adopts the traditional manual working mode, the manual working is adopted from planting, fertilizing to harvesting, the labor intensity is high, and the production efficiency is low. The traditional small-scale planting mode and the current situation of low production mechanization level seriously limit the further development of the radish industry, and particularly the radish harvesting link has high labor intensity and high labor cost. The traditional agricultural cultivation mode can not meet the requirement of modern production, and in order to adapt to the development of the modernization, the cultivation is carried out by using machines instead of manpower, and the great popularization of agricultural mechanization becomes a necessary trend of the modernization agriculture.

At present, the common harvester in the market mainly has two kinds, and the first kind is large-scale turnip harvester, not only is equipped with special driver's cabin, provides good operational environment for operating personnel, and it is efficient to reap moreover, and the major work principle is: the soil spade is shoveled the soil at the machine walking in-process to make the carrot basically separate with soil, the place ahead is carried the chain with the lift sprocket and is pressed from both sides the carrot that is about to separate with soil, along with promoting the rotation of carrying the chain, the carrot just is carried the upper end, tail end at promotion carrying chain is provided with the base cutter, when the carrot passes through here the base cutter with it from rhizome combination position cutting off, then the stem leaf of cutting off is sent the top and then is cleaned out the machine, the meat root of carrot then directly falls into on the horizontal transport belt of below, carry its collection box in the rear by horizontal transport belt, thereby realized the integration from separation, the lift of carrot, the cherry is collected. However, in agricultural production in China, the large-scale radish harvester is limited by the current situation that land in China is scattered and is mostly planted by individual households, is not suitable for large-scale harvesting machinery to operate, and on the other hand, the large-scale machinery is expensive in manufacturing cost and high in using and maintaining cost.

The second type is digging machinery which is dragged behind a tractor, needs to be matched with the tractor for use, only can dig radishes, does not have the function of collecting the radishes, and the radish collection after digging is scattered on the ground and still needs to be finished manually. At present, the harvester that common in the market is mostly miniature, has only replaced traditional artifical excavation process, shovels out the turnip from soil, but does not collect the turnip after shoveling out, but scatters on the ground, still needs the manual work to go to pick up, so efficiency still is lower than foreign machinery. In addition, most of the harvesters on the market are of a trailer type, do not have power, and need to work together with a matched tractor, so that the harvester can be used only by using the matched tractor head, and the use is inconvenient. Therefore, the radish harvesting machine which is small and integrates the functions of digging and collecting the radish is very important.
