Grain dividing method using pneumatic crop divider for hybrid rice seed production machinery

Abstract

The invention discloses a pneumatic crop divider used for a hybrid rice seed production machine and a grain dividing method thereof, comprising a guide section, a transition section and a grain dividing section which together form a rigid structure; the working end of the guide section is used for inserting The conical and smooth structure between the bottom of the male parent plant and the female parent plant, the connecting end is connected to the cutting section smoothly through the transition section; One end of the diversion pipe is communicated with the hollow cavity of the dividing section, and the other end is communicated with the outside world; the interior of the dividing section is coaxially fixed with a mixed flow tube for introducing gas; the inlet end of the mixed flow tube is externally connected to the blower The air intake pipe is evenly opened with several air flow holes at the bottom. The invention realizes the non-destructive and flexible complete separation of male parent and female parent plant, avoids damage to plants caused by pollination machinery, and mis-harvesting of male parent ear by seed harvester to affect seed purity, and improves the quality of hybrid rice seed production, pollination and harvesting.

Description

technical field [0001] The invention relates to a crop divider for agricultural machinery field operations, in particular to a pneumatic crop divider for hybrid rice seed production machinery and a crop dividing method, belonging to the field of agricultural machinery. Background technique [0002] Hybrid rice has made outstanding contributions to solving food problems. Hybrid rice seeds are the basic material for its production, but rice is a non-strict self-pollinating crop, and the natural hybridization rate is extremely low, so seeds must be produced every year in order to provide excellent seeds for rice production. At present, the male parent and female parent of hybrid rice seed production usually adopt agronomic interval planting with a row ratio of 2:6 to 8, and also began to try to use 6:24 to 30 to adapt to the planting agronomy of mechanized pollination. In the production of hybrid rice seeds, The plants at the pollination and harvest periods are taller, and par...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome hybrid rice seed production pollination machine, male parent harvester because adjacent male parent, female parent are interwoven with each other in operation process, and simple and simple crop divider can not be flexible and well separated and causes more serious problems to male parent and female parent. Large mechanical damage, which affects the yield of rice seeds, etc., provides a pneumatic grain divider and its method for hybrid rice seed production machinery. The male parent and the female parent are separated from the ground through the bottom guide section. Then the male parent and the female plant are gradually separated from the bottom to the top by the inclined section, and the airflow above the section separates the plants completely to avoid damage to the plant by operating tools during pollination and damage to the female plant when the male parent is harvested
