Description

Technical Field

[0001] This utility model relates to the field of finger clip ejector seeding component, and in particular to an ejector seeding channel for a seeding device and a housing component using the seeding channel. Background Technology

[0002] The finger-clamp ejector precision seed metering assembly features high structural strength, stable seed pickup, and eliminates over-seeding and missed-seeding, significantly improving sowing efficiency. It also offers multiple uses in one machine, comprising a seed metering assembly, seed nozzles, seed metering blocks, connecting blocks, a fastening ring, and a housing. The seed metering assembly is placed inside the housing, and the fastening ring and housing are then fastened. During sowing, the seed metering assembly ejects the seeds, which are then distributed to the ground through the seed nozzles. Depending on different operational requirements, different numbers of seed metering blocks can be selected, along with corresponding sized connecting blocks and seed nozzles, ultimately achieving the desired yield.

[0003] Due to the different soil conditions in different regions, the required machine casing size varies to achieve the best sowing effect. In order to meet the requirements of a large-sized machine casing, if the entire seed metering component is enlarged, the cost will increase, the weight will increase, the processing difficulty will increase, and it will be difficult to guarantee the roundness of the inner wall of the seed metering component, thus making it impossible to maintain sowing.
