Multilayer stubble-cleaning rotary-cultivation fertilizing seeding machine

Abstract

The invention discloses a multilayer stubble-cleaning rotary-cultivation fertilizing seeding machine, which relates to the technical field of the seeding machine. The seeding machine comprises a transmission case, a main stander and a fertilizing device assembly, and the seeding machine is characterized in that the main stander is sequentially fixedly provided with a seed-row stubble-cleaning cutter shaft assembly, a disc-type rotary-cultivation cutter shaft assembly, a profiling ground wheel assembly, an arc deep loosening cutter and layering fertilizer assembly, a wheel-type compact furrow-opener assembly and a seeding device assembly from right to left. A cutter shaft of the seed-row stubble-cleaning cutter shaft assembly and a cutter shaft of the disc-type rotary-cultivation cutter shaft assembly are connected with the transmission case, and the profiling ground wheel assembly supplies power to a fertilizer on the fertilizing device assembly and a seeding mechanism on the seeding device assembly. According to the invention, the application range of the seeding machine can be enlarged, the utilization efficiency can be improved, the seeding machine is not only applicable to the high efficient fertilizing and seeding of corns, but also is applicable to the high efficient fertilizing and seeding of crops such as cotton, soybeans, and sunflowers, the seeding machine is insensitive to the soil moisture content and the quantity of the stubbles, and the operating efficiency is high.

Description

technical field [0001] The invention relates to the technical field of seeders. Background technique [0002] There are many machines for fertilizing and seeding of row crops at home and abroad, mainly large-scale machines abroad, which are expensive, and domestic small and medium-sized machines, which are cheap but functionally less effective. When working on plots with high stubble and a large amount of straw in the previous crop, the problem of straw entanglement is common, which makes the current seeder unable to operate smoothly and continuously, which seriously limits the production efficiency and seeding quality of the seeder. [0003] At present, the fertilization depth of domestic and foreign fertilization seeders is generally shallow, most of which are less than 10cm. Due to the close distance between the fertilizer and the seeds, the problem of seedling shortage and broken ridges caused by the burning of the base fertilizer is common and serious.

Problems solved by technology

[0002] There are many machines used for fertilizing and seeding row crops at home and abroad. Foreign countries mainly use large-scale machines, which are expensive. Domestically, small and medium-sized machines are mainly used. Although the price is low, the functional effect is poor.

When working on land with high stubble and large amount of straw, the problem of straw entanglement is common, which makes the current seeder unable to operate smoothly and continuously, which seriously limits the production efficiency and seeding quality of the seeder.

[0003] At present, the fertilization depth of domestic and foreign fertilization seeders is generally shallow, most of which are less than 10cm. Due to the close distance between the fertilizer and the seeds, the problem of seedling shortage and broken ridges caused by the burning of the base fertilizer is common and serious. In order to prevent the burning of the fertilizer, only The method of applying less base fertilizer and topdressing in stages cannot meet the super-high-yield technical requirements of one-time high-efficiency fertilization. In the context of rural labor shortage, it is often difficult to implement staged topdressing, and it is difficult to bring out the high-yield potential of crops.

[0004] The volatile runoff of nutrients in the shallow layer of fertilization is relatively large, and the utilization rate of fertilizers is low. The nutrients in the 10-30cm root dense layer cannot be replenished, especially the less mobile nutrients such as phosphorus. The core soil layer is seriously depleted. Unfavorable premature yield decline is relatively large. If these problems cannot be effectively solved, it will be difficult to achieve a breakthrough in crop yield, and the utilization rate of water, fertilizer and fertilizer cannot be improved.

[0005] Under the condition of poor soil moisture, the soil cannot fall back quickly after deep loosening and ditching, the upper layer of fertilizer is too little, the proportion of the lower layer is too large, and the growth of seedlings is poor. Working on over-dried and hard land, the resistance is too large, and the soil is too large. There are many blocks, the quality of the seed bed is poor, the rate of missed seeding is high, the depth of seeding is different, the emergence of seedlings is irregular, and the phenomenon of seedling shortage and broken ridges is serious. When working in heavy and over-humid land, the deep loosening ditch cannot be bridged, and the circular Disc openers and overburden rollers are severely clay-soiled, and the sowing depth is difficult to control, seriously affecting seedling emergence and fertilizer layering effects. The dislocation of disc openers and sub-pine beds, uneven seed beds also cause different depths of sowing, and high-level seeding. The increase of drop point error has affected the uniformity and uniformity of seedling emergence. If these problems cannot be solved well, the advantages of full-layer fertilization of corn subsoiling will be difficult to give full play to
