Rice is one of the staple foods in the world and approximately half of the world population feed on it . The aim of rice breeding is always to increase rice yield . Yield-related traits of rice, such as total spikelet number per plant, filled spikelet number per plant, seed-setting rate, thousand kernel weight, grain length and grain width, directly determine its production . However, in order to evaluate the aforementioned traits, threshing is an essential pretreatment. Therefore, it is significant to study on the rice thresher .
Since the machine-vision technique is widely used in agriculture , more and more automated instruments are actualized for the traits evaluation with the rice samples threshed previously . It is obvious that the procedure of threshing limits the automation and the efficiency of rice traits evaluation to a large degree. Therefore, in order to achieve the purpose, a type of rice thresher with the features of whole-feeding, no residue, and automation is really needed.
Threshing is an essential pretreatment in rice yield-related traits evaluation and rice thresher is an important study of agricultural machinery automation. However, traditional threshers aim at threshing filled grains with simple function, which are inapplicable to high-precision and automatic yield-related traits evaluation of rice. And the conventional threshing method for the traits evaluation is still manual.
To improve it, Zeno Farm Machinery developed a whole-feeding and automatic rice thresher for single plant. The thresher adopted a hierarchical multi-roller rolling method to thresh filled and unfilled grains respectively. A fish scale sieve plate was designed to separate the grains from the straw .Our rice thresher machine had the advantages of high precision, low breakage and no residue. Thus, the thresher provides strong support for high-precision and automatic yield-related traits evaluation of rice.
The corn thresher machine generally performed high separation precision, due to the specifically designed threshing sieving unit, in which the fish scale sieve plate was adopted. In addition, centrifugal fan worked with the sieving unit in collaboration to eliminate the threshing residues.
