Description

Technical Field

[0001] The utility model relates to the field of rice breeding, in particular to a seed selection device for high-quality rice planting. Background Art

[0002] In rice breeding, it is a common practice to use salt water to select seeds. The basic principle of this method is to use the density characteristics of salt water to distinguish different seeds. Specifically, by adjusting the concentration and density of the salt water, the high-density seeds will sink to the bottom of the water, while the low-density seeds will remain on the surface of the water. In this way, only the low-quality seeds floating on the water surface need to be removed, and the high-density seeds can be retained. For example, a salt water seed selection machine is disclosed in Chinese Patent Publication No. CN104226459A. The device can remove pathogenic spores attached to the surface of seeds, reduce the harm caused by seed disease, and ensure that the density of the salt water is more accurate. It can also place the superior and inferior seeds in different boxes, greatly improving the efficiency of seed selection.

[0003] However, when salt water is injected into the container, low-quality rice seeds will float up, and personnel are then required to scoop out all the rice seeds on the water surface, and then manually scoop out the rice seeds that have sunk to the bottom and separate them from the rice seeds on the water surface. This method is time-consuming and labor-intensive, and seriously reduces the efficiency of seed selection. Utility Model Content

The rice seeds that sink to the bottom will enter the lifting pipe 13 from the feeding port 14. When the second motor 11 is started, the rotating shaft 15 drives the screw feeder 16 to rotate, and the qualified seeds are output by the discharge piece through the screw feeder 16 to avoid manual salvage.

[0023] like Figure 2 and Figure 3 As shown, the discharge member includes a sleeve 9 fixedly mounted on the upper end of the lifting pipe 13, a discharge pipe 10 adapted thereto is mounted on the sleeve 9, and a positioning block 19 is fixed to the top end of the sleeve 9, a positioning groove 18 adapted to the positioning block 19 is provided at the upper end of the lifting pipe 13, and the sleeve 9 can be quickly loaded and unloaded by engaging the positioning groove 18 with the positioning block 19.
