Abstract

The invention relates to an airflow first-order centralized discharge type wheat seed metering system, and belongs to the technical field of agricultural machinery. The airflow first-order centralized discharge type wheat seed metering system comprises a fan (1), a rack (2), a grooved wheel type centralized discharge device (3), a Venturi jet feeder (6), a pleated pipe (7), a bend pipe I (8), a bend pipe II (9), a distributor (10), a seed guide pipe I (11), a seed guide pipe II (12), and a fixing ring (13). The Venturi jet feeder is combined with a seed supply pipe, seed flow and air flow are fully mixed, the seed supply uniformity is improved, meanwhile, the uniformity of the seed metering process of the seed guide pipes on the distributor subsequently is improved, the seedling missing phenomenon in the wheat growth process is avoided, and the difficulty of field management can be reduced; and meanwhile, the displacement consistency of all rows is good, the requirement of wheat drill seeding operation is met, multi-row seed metering can be achieved at a time, time is effectively saved, and the labor intensity of farmers is effectively relieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to an airflow first-stage collection and discharge type wheat seeding system. Background technique [0002] Wheat is one of the most important food crops in my country and even in the world, and it is also a pillar crop in arid and semi-arid areas in my country. Wheat sowing is one of the important links in wheat planting. The "one device and one row" type seed metering device widely used at present relies on increasing the number of seed metering devices to achieve increased operation, which has caused problems such as large size of the seeder and low operating efficiency. Contents of the invention [0003] In order to solve the problems raised in the background technology, the present invention provides an airflow one-stage collection and discharge wheat seeding system, which realizes the whole process of mechanized sowing of wheat, and the whole machi...
