Description

Technical Field

[0001] The utility model belongs to the technical field of seed selection equipment, and specifically relates to a seed selection equipment for rice planting. Background Art

[0002] Before rice is planted, it is necessary to screen the seeds to remove impurities, such as empty shells, to ensure the best planting results. The existing methods for rice seed selection include wind selection, screening, salt selection, mud selection, etc.

[0003] Salt selection is salt water seed selection, which is to put the seeds in salt water of a certain concentration and use buoyancy to separate good seeds from bad seeds. The buoyancy of salt water is greater than that of fresh water, and it can float some unfull seeds.

[0004] However, there are still certain problems in the use of brine seed selection equipment in the prior art. For example, when selecting seeds, the brine concentration is detected by a manual handheld density meter. Because this detection method uses manual readings, the error will be relatively large. When removing bad seeds, the bad seeds need to be manually picked up, which is labor-intensive and inefficient. When removing bad seeds, some brine will inevitably be carried with it, and the brine cannot be recycled, resulting in unnecessary waste.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies.

[0006] Therefore, in order to solve the above problems, the utility model provides a seed selection device for rice planting. Utility Model Content

[0007] In order to overcome the above technical problems, the purpose of the present invention is to provide a seed selection device for rice planting. First, salt water is prepared in the seed selection box, and the rice seeds are placed in the basket. Then, the basket is placed in the seed selection box, and the salt water in the seed selection box is stirred by the stirring mechanism, so that the seeds can be quickly distributed in the salt water, thereby improving the seed selection effect. After stirring for a period of time, the stirring is stopped, and after the good seeds are separated from the bad seeds, the valve on the drainage pipe is opened, so that the bad seeds can flow into the collection box through the drainage pipe together with part of the salt water for separation and collection. After the separation is completed, first rotate the rotating rod so that the stirring blade rotates a certain angle above the seed selection box, which makes it easier to take out the basket. After the basket is taken out, start the water pump, and the water pump will transport the brine in the collection box back to the inside of the seed selection box to achieve the recycling of the brine. Then, part of the brine in the seed selection box is transported to the ion tester, and the concentration of the brine is tested by the ion tester. If the test result meets the requirements, the seed selection operation can continue. If the detected concentration is small, add an appropriate amount of salt first, and then prepare the brine that meets the requirements and then carry out the seed selection operation again.
