Corn in-line duckbill forced discharge device

Abstract

The invention relates to the technical field of a corn seeding machine, specifically to a direct-insertion type duckbill forced seed discharging device for corn. The device is characterized by comprising an installation top plate fixedly connected with a frame of a seeding machine, wherein the installation top plate is provided with a camshaft which is provided with a cam assembly; and a pulling sheet assembly is arranged on the plate surface of the installation top plate at a position corresponding to the cam assembly and is connected with a duckbill assembly via pulling wires. According to the invention, the device can utilize instant dynamic load to shake off soil adhered on the duckbill assembly which is taken out from soil, so the precise corn seeding machine does better in controlling qualified corn plant spacing; a pulling sheet frame is used, so good strength and high precision are obtained; the pulling sheet is used to pull four pulling wires, so structure is simple, and installation is convenient; the direct-insertion type duckbill adaptable to an direct-insertion type rod is adopted, so the problems of soil entering when the duckbill assembly enters the soil and incapability of seed discharging when the duckbill assembly is taken out from the soil; and the device can be timely forced to start according to operation cycles. The device can improve production efficiency of precision corn seeding and mitigate labor intensity of farmers.

Description

technical field [0001] The invention relates to the technical field of corn seeders, in particular to a corn in-line duckbill forced discharge device. Background technique [0002] At present, the promotion area of ​​double-furrow sowing with full film covering in Gansu Province has exceeded 6.7×105hm 2 . Since the mechanized operation of sowing, harvesting, and residual film picking is still blank, and the existing corn on-demand planters and hand-push corn hole planters are labor-intensive and low in production efficiency; Relying on the traditional duckbill hole sowing device, there are problems such as the duckbill is not opened in time, the soil is easy to block, and the seeds are not easy to enter the hole, which seriously restricts the rapid development of the full-film double-furrow sowing technology and cannot meet the actual needs of corn sowing in Gansu. Contents of the invention [0003] The object of the present invention is to avoid the defects of the prior...
