Embodiment Construction

[0015] Fig. 1 is the front view and the left side view of the circular tube air suction seed metering device. The seed suction pipe 1 is respectively provided with corn air suction holes 2 and wheat air suction holes 3 along the axis according to the row spacing of corn and the row spacing of wheat. The line of symmetry has a seed groove 5, a seed scraping slope 6 and a seed filling window 7, the inoculation funnel 8, the seed rubber strip 9 and the seed box 11 are all installed on the U-shaped rigid body cover, and the seed box is a square pyramid, so that the seeds are concentrated Flow to the position of the air suction hole, and the bottom of the seed box is provided with a seed unloading port and a seed unloading insert 10.

[0016] Fig. 2 is the top view of the installation structure of one end of the circular tube type air suction seed metering device. The above seed suction pipe 1 is respectively provided with corn air suction holes 2 and wheat air suction holes 3 along...

Abstract

The invention relates to a round tube air-absorbing feeder which is formed by a pipe with its length equals breadth of feeder as the main body of feeder, feed-absorbing pipe and feed cases. It separately opens some feed-absorbing holes according to the axis of feed- absorbing pipe along the line-spacing of core and wheat. The feed-absorbing pipe is connected with negative air extractor; spring beading and drive axle are fixed on both ends of feed- absorbing pipe; the cap of feed-absorbing pipe is connected with extractor pipe. A general seed case set is according to each line's feed place and the core is a U-shaped solid body cover which has plug hatch, feeding hatch, seed groove and seed-shaving deck, seed case and inoculation funnel are also fixed on it.

Description

Technical field [0001] The invention relates to a seeding device for a seeder used in agricultural production, in particular to a dual-purpose seeding device for corn and wheat. Background technique [0002] Corn and wheat are the main food crops in northern my country, and the seeder is the most basic operating equipment. For the vast areas where two crops of corn and wheat are planted in one year, two seeders for corn and wheat need to be purchased respectively. With only about a week to plant each crop, planter utilization is low. Apparently, it is an effective way to reduce investment and improve equipment utilization to realize the dual-use of corn and wheat in one planter. [0003] Corn and wheat are planted with different row spacing and grain spacing, as well as different seed shapes and sizes. For a seeder with a certain width, the number of rows that can sow wheat at the same time is about three times the number of rows of corn, and the sowing distance of corn i...
