Seed metering and fertilizer feeding device of seeder

Abstract

The invention relates to a seed metering and fertilizer feeding device of a seeder. The seed metering and fertilizer feeding principles and structures are essentially the same, namely, the work stations are staggered at a mechanical angle. The device comprises a seed fetching device, a fertilizer fetching device, a feed pipe and a fertilizer pipe. The device is characterized in that the device also comprises a conveyor belt mechanism installed below the feed pipe and the fertilizer pipe; conveyor belts in the conveyor belt mechanism are oblique downwards; transverse small grating plates for separating the seeds or fertilizers are also installed on the surfaces of the belts along the forward directions; the distances between the small grating plates are longer than the dividing distance between the work station of the seed fetching device and the work station of the fertilizer fetching device; and enlargement of the seed charge distance is realized through synchronous operation. The device can improve the hill distance accuracy and the seed and fertilizer isolation, can increase the operation speed and is suitable for planting of such sparse tilling crops as maize, cotton and the like and planting of grains, beans or intercropping of two inter-row crops.

Description

technical field [0001] The invention belongs to a sowing and fertilizing machine in the field of agricultural machinery, in particular to a seeding and fertilizing device for a seeding machine. Background technique [0002] The sowing and fertilizing machinery in the prior art can realize many synchronous hole sowing of seeds and fertilizers in the same ditch, but the separation effect of seeds and fertilizers is not very good, and it is not suitable for increasing speed operations. Analyzing their common ground: it is to stagger the positions on the seed picker and the fertilizer picker on the coaxial mechanical angle, so that the seeds falling into the soil ditch are separated from the fertilizer. Because the distance between the seed and fertilizer station on the indexing circle between the seed extractor and the fertilizer extractor is much smaller than the actual indexing distance on the profiling ground wheel, and the seeds and fertilizers occupy a certain time angle o...

AI Technical Summary

Problems solved by technology

Because the distance between the seed and fertilizer station on the indexing circle between the seed extractor and the fertilizer extractor is much smaller than the actual indexing distance on the profiling ground wheel, and the seeds and fertilizers occupy a certain time angle on the indexing circle , There are also factors such as the separation characteristics of the seed extractor and the fertilizer extractor itself, which make the boundary between the seed and the fertilizer fall into the soil ditch unclear, causing the fertilizer to trail, and the contact between the seed and the fertilizer
