A linkage imitation corn single-grain no-tillage precision sowing fertilizer applicator

Abstract

The invention relates to the field of agricultural machinery, and particularly discloses a linkage profiled corn single-seed no-tillage fine-sowing fertilizer applicator. The linkage profiled corn single-seed no-tillage fine-sowing fertilizer applicator comprises an applicator frame with a gearbox, and is characterized in that a roller cutter shaft connected with an output shaft of the gearbox is connected with the lower portion of the applicator frame; double-spiral arched straight knives are arranged on the roller cutter shaft and are the same in low coverage; a fertilizer application coulter is installed at the bottom end of the applicator frame; a depth limit wheel is arranged at the front end of the applicator frame; the applicator frame is provided with a single-hung pull rod; an integrated sowing subassembly formed by a scoop type seed sowing device and a double-disk coulter is arranged below the single-hung pull rod; a single linkage profiled pressing mechanism is arranged behind the sowing subassembly. The linkage profiled corn single-seed no-tillage fine-sowing fertilizer applicator is novel, reasonable and simple in structure, convenient to operate and adjust, reliable in use, high in adaptability and efficiency, good in economical efficiency, and capable of being widely applied to corn no-tillage fertilizer application unit fine sowing machines, and promoting popularization of the advanced technology of protective cultivation.

Description

(1) Technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a linkage profiling corn single-grain no-tillage precision sowing fertilizer applicator. (2) Background technology [0002] At present, in the corn-wheat rotation area in my country, the conservation tillage technology has been vigorously promoted for more than ten years. The corn no-tillage planter basically uses the shovel type ditch opener to fertilize and sow. The difference between conservation tillage and traditional tillage is that in Sowing is directly sown on the surface covered by the straw of the previous stubble, so the quality of no-tillage sowing is the key to conservation tillage technology. [0003] In the prior art, the seedling belt passive roller is used to clear the stalks, and the hoe and shovel type ditch opener is used as a combined operation tool for ditching, fertilizing and sowing. The problems of this machine tool are: (1) The straw...

AI Technical Summary

Problems solved by technology

The problems of this machine tool are: (1) The straw cleaning rollers in the seedling belt are passive cleaning, and the straw is easy to cause blockage when the ground surface is fully covered, and cannot work normally; In the case of full coverage of straw, the root stubble is likely to cause pieces of flaky soil clods and larger soil clumps, and the performance of crushing the soil is poor, which seriously affects the emergence rate and cannot meet the technical requirements of single-grain precision sowing of corn; (3 ) Hoe shovel type fertilization and sowing openers are rigidly connected with the frame. Working on uneven ground will easily cause inconsistent sowing depths, affect seed germination, and seedlings will not emerge neatly, eventually resulting in reduced production.
