Problems solved by technology

However, due to the relatively large weight of large seeds, it is not realistic to use winnowing, and the use of fixed sieve screening also requires too many sieve types due to different tree species and seed grading standards, and the cost of seed grading is high and time-consuming. Therefore, It is especially necessary to develop related large seed sorting equipment

Embodiment Construction

[0019] 1-iron bracket, 2-adjustable seed sieve tray, 3-rotating steel bar at the bottom of the sieve, 4-rotating steel bar fixing rod, 5-rotating handle, 6-fixing nut, 7-control adjusting rod, 8-adjusting rod Adjustment handle, 9-"half I-shaped" fixing frame, 10-adjustment hole, 11-adjustable seed sieve tray fixing bolt, 12-adjustable seed sieve tray fixing bolt fixing hole, 13-sieve tray installation positioning bolt.

[0020] attached Figure 1-5 Given the specific embodiment of the present invention, the screening and grading of Quercus variabilis seeds is now taken as an example for illustration. Referring to the research on the size of Quercus seeds at home and abroad, the short diameter length of Quercus cork I seeds (large seeds) is >2cm, that of II seeds (medium seeds) is 1.5-2cm, and that of III seeds (small seeds) is 1.0-1.5cm , Grade IV seeds (incomplete mature seeds) <1.0cm. The specific operation steps are:

[0021] The total height of the iron support is 50cm....

Abstract

An adjustable large-size seed classifier includes an irony support, four adjustable seed sieve trays, four control adjustment rods, eight fixing nuts, rotation handles and Z-shaped fixing frames; the bottom of each adjustable seed sieve tray is provided with sieve bottom rotation steel bars, and one end of each rotation steel bar and a pin bolt are fixedly connected to a rotation handle of a control adjustment rod; during operation, the control adjustment rods move to drive the rotation handles to rotate, and then drives the sieve bottom rotation steel bars to change the inclination angles so as to evenly and consistently adjust the bore diameter of the sieve bottom. The adjustable large-size seed classifier can gradually classify the seeds through adjustment of the installation number of the adjustable seed sieve trays and adjustment of the bore diameter by adjusting the inclination angles of the sieve bottom rotation steel bars by means of the control adjustment devices, and then the efficiency and the accuracy of seed classification can be improved, and the utilization efficiency of the seeds can be improved. The adjustable large-size seed classifier is low in cost, is simple to operate, can ensure the accuracy of classification, reduce the lobar intensity, and can be applied to production and scientific research practices.

Description

Technical field: [0001] The invention belongs to the field of forestry seedling cultivation, and specifically relates to a large-grained seed grading technology. According to the critical value of the short diameter length grading standard of different tree species, mechanical devices with different apertures are used for seed grading, thereby improving the speed and quality of seed grading. Background technique: [0002] Forest tree seeds are the basis of forestry production and are special commodities with vitality. They have been concerned by producers, operators, users and seed management departments for a long time, and their quality directly affects the germination and growth of seedlings. Therefore, to ensure the smooth implementation of forestry projects, improve the productivity and quality of seedlings, and select different grades of seeds according to different seedling production requirements to improve the utilization efficiency of seeds and seedlings are the pri...
