The center drive strong push type precision metering device has a size of 135×102×100. Compared with the multi-function precision seeder seed metering device, the conventional outer groove wheel sorting mechanism and the precision transmission short shaft are reduced, and the transmission power is directly The seeding shaft is applied to the shaft of the seeding wheel by the seeding machine, and the force is stable and the frictional resistance is small. There are two rows of small holes with a hole diameter of 3mm, a row of 8mm holes and a large row of finger-shaped seed grooves. When planting, the small and medium seeds in the seed holes are forced out from the inside and outside by the seeding mechanism. There is no shortage of seedlings and ridges caused by clogging of seeding holes. It can precisely sow seeds with a particle size of 1-7mm, such as cabbage, rape, alfalfa, millet, sesame, radish, tomato, pepper, flax, mung bean, sorghum, etc. Small and medium-grain crops and semi-precision sowing large crops such as corn, soybeans, and cotton. A seed cleaning tank is added at one end of the seed metering device, and the remaining seeds in the seed box can be quickly and completely cleaned for use in the test plot so as not to cause seed mixing. The metering device interface conforms to the agricultural machine standard, and the lower assembly base is added, which can be assembled on a variety of models, and the line spacing is convenient.
This new product will provide mechanical and precise seeding for a variety of small seed crops such as rapeseed in China, improve production levels, and provide technical and material security.
A new generation of small seed precision seed metering device was successfully developed in Baoji, Shaanxi
Zhang Yuwen, a senior agronomist at Baoji Agricultural Science Institute, Shaanxi Province, has been engaged in the research of precision seeding technology for small seeds for nearly 20 years. The “multi-function precision seeder seed metering device†developed by Shaanxi Province has passed the Shaanxi Provincial Science and Technology Department and Shaanxi Agricultural Machinery Quality Supervision and Appraisal Station. The identification and testing has reached the domestic leading level and won the national patent authorization. It has demonstrated more than 200,000 mu of rapeseed, millet, alfalfa, sesame seeds, small medicinal materials and vegetables in 24 provinces and municipalities across the country, and achieved a larger society. The economic benefits were generally welcomed and won the third prize of 2004 Science and Technology in Shaanxi Province. This year's new generation of "central drive strong push type precision seed metering device" has been successfully developed and produced. This product is a further improvement in performance quality based on the "multi-function precision seed metering device". The product is produced by engineering plastics. It has the advantages of simple structure, reliable operation, precise seed sorting, flexible rotation, convenient assembly adjustment, quick and thorough cleaning of remaining seeds, small size, durable and beautiful appearance. It has applied for national invention patent. The application number is .3, the product has been mass-produced and successfully installed on various types of planters, including 2BJ-10/14 type vegetable precision seed drill produced in Guangdong, 10cm row spacing, and the amount of acreage control reached 200g, which solved the problem. The problem of planting vegetables in the region is very popular.
