Description

Technical Field

[0001] The utility model relates to the technical field of pollen collecting devices, in particular to a pollen collecting device for corn breeding. Background Art

[0002] Corn breeding is mainly based on the use of hybrid advantages. It starts with the selection of inbred lines and takes the selection and use of single-hybrid varieties as the main purpose. The selection criteria for inbred lines are high self-reproduction yield, high quality, multi-resistance, density tolerance and excellent comprehensive traits. The most important feature of corn is natural cross-pollination. The field composition of the natural pollination population is in a highly heterogeneous state, and the individual genotype is in a highly heterozygous state. This determines that in the natural pollination population of corn, the comparison of phenotypes between plants is not very meaningful, and a certain genotype selection process must be used to correctly decide on the choice. At the same time, due to the high heterozygosity of individual genotypes, phenotypic selection is unreliable, and a large number of individuals must be test crossed or their offspring must be finally bred into excellent hybrid varieties.

[0003] For example, a pollen collection device for corn breeding disclosed in the authorization announcement number CN220557121U includes a collection mechanism, wherein a slapping mechanism is fixedly arranged inside the collection mechanism;

[0004] Although the worker can put the cornflowers into the collecting port of the device, the output end of the driving motor in the slapping mechanism can drive the circular plate to rotate, the circular plate can drive the driving rod to rotate, and the end of the driving rod can drive the pushing column to move back and forth, so that the moving plate can be moved together, and at the same time, the moving plate can drive the two rotating rods to rotate, and the ends of the two rotating rods can drive the two powder-slapping plates to rotate in relative directions, so that the two powder-slapping plates can reciprocate and slap the cornflowers, so that the corn pollen can continuously fall, thereby improving the collection efficiency of the corn pollen and reducing the pressure of manual labor;

[0005] However, the problem that the existing pollen collecting device is not conducive to convenient reciprocating transmission filtering and discharging pollen, scraping and cleaning cornflowers, and automatically discharging and collecting a large amount of corn pollen when in use is not solved, and it is not convenient to discharge pollen by reciprocating transmission vibration drive and discharge cornflowers after pollen discharge conveniently and quickly, which greatly affects the convenience of cornflower discharge and the convenience of collecting a large amount of corn pollen.
