Description

Technical Field

[0001] The utility model belongs to the technical field of highland barley planting, in particular to an agricultural seed selection mechanism. Background Art

[0002] Highland barley is an annual herb of the Poaceae family and the genus Hordeum. It has three upright, smooth stalks that can reach 100 cm in height. The leaf sheaths are smooth, with two lobe ears on both sides that embrace each other. The leaf tongue is membranous and the leaves are slightly rough. Before planting highland barley, in order to ensure the quality of the planted highland barley, the highland barley seeds need to be screened. Therefore, a grain selection mechanism is needed to screen the highland barley seeds.

[0003] Among them, after searching, it was found that there is an application number of CN202222829515.5, which discloses a grain selection device for highland barley planting, including a U-shaped box, a ventilation slot is opened on the horizontal part of the U-shaped box, and the salt water seed selection box is filled with seed selection salt water when in use, and the salt water seed selection box is placed under the inverted V-shaped outlet hopper, and the blower is started, and the highland barley that needs to be selected is slowly poured into the V-shaped funnel. When the highland barley enters the ventilation slot, some lighter and less full seeds and some straw and other impurities are blown out of the U-shaped box from the left side under the action of the blower, and the remaining part of the seeds falls into the salt water seed selection hopper. In the box, the buoyancy of the seed selection salt water is greater than that of fresh water, and some incomplete seeds can be floated under its action. After the seed selection is completed, the upper T-shaped handle is turned to remove the internal threaded cover of the seed selection salt water, and the unqualified seeds are brought out of the salt water seed selection box through the drainage threaded pipe. Finally, the lower T-shaped handle is turned to discharge all the selected seeds in the salt water seed selection box, and a certain amount of clean water is used to clean them. The filter net can effectively prevent the outflow of highland barley seeds. The grain selection device is simple to operate and easy to use. It can quickly and effectively select highland barley, reduce manpower and material costs, and is conducive to the germination rate of highland barley seeds, increase yield, and reduce the cost of growers.

[0004] However, after research, it was found that the device screened out impurities in highland barley seeds by soaking them in salt water, and there was no structure to dry the soaked seeds. Wet seeds were prone to mold and difficult to store, which would affect the quality of the seeds. In addition, the device could only classify the seeds into light and heavy types, and could not perform more fine screening on seeds with high density. The screening was not fine enough and the screening effect was not good enough. Therefore, a new device was provided to solve this problem. Utility Model Content
