Description

Multi-functional Precision Seeding stubble cleaner

The utility model belongs to agricultural machinery, relates in particular to the combined agricultural machinery of sowing and stubble-cleaning.

Known farm machinery mostly is the special plane special use, do not have multiple efficacies, and patent 96227471 has disclosed a kind of multifunctional seed drill, comprise wheel, protect frame, basket frame, frame, seed manure container, handrail, cabin, wheel crotch, one axle by chain drive is arranged in the seed manure container, a vibrating wheels and at least one group of seeding wheel and the chemical fertilizer wheel with uniform hole on excircle are arranged on this, this sowing function is broadcast the seed of different cultivars, but it can not regulate the depth and the stubble-cleaning of farming, and the seeding quantity number can not accurately calculate.

The purpose of this utility model be to provide a kind of can the various kinds of sowing crops and have stubble-cleaning sowing effect height, and can adjust farming depth seeding quantity accurately and multi-functional Precision Seeding stubble cleaner that can arbitrary combination.

The purpose of this utility model is achieved through the following technical solutions: this multi-functional Precision Seeding stubble cleaner comprises frame, be contained in the line shaft on the frame, be contained in land wheel and driving wheel on the line shaft, the frame front end is fixed with hitch structure, combination is equipped with sowing assembly and stubble-cleaning assembly by connecting piece on the frame, be contained in a locating hole that above high and low position is different is arranged on the hanger in the hitch structure, on the driven axle in the sowing assembly coupled accent amount structure is arranged, and frame is forebay and the assembling of afer bay two parts, the appearance hopper that is contained in the sowing assembly on the forebay has three openings, there is coupled logical sowing leg in the bottom of opening, and the rear portion of forebay has four stubble-cleaning legs by the stubble-cleaning assembly of connector assembling; The hopper of adorning the sowing assembly on the afer bay is the groove formula, seven discharge gates are arranged in the hopper, and there is coupled logical sowing leg in each discharge gate bottom, two rows before and after the sowing leg is divided into, stagger before and after the adjacent two sowing leg positions, afer bay is by connector combination tipping mmi machine frame back.

This tiller-seeder not only has stubble-cleaning and sowing dual-use function, because of the hole of differing heights is arranged on the traction hanger, so the depth that can regulate farming, the sowing assembly and the total Chengdu of stubble-cleaning that are contained in addition on the frame are that combination is assemblied on the frame by connector, therefore user's arbitrary combination as required, in the sowing assembly, accent amount structure is housed, so also have the amount of broadcasting accurately and can sow the advantages of different cultivars crops, because stubble-cleaning leg and sowing leg are more in this machine, so stubble-cleaning and sowing effect are all very high.This machinery especially is fit to the four-wheel tractor with the high-power that the rural area scope of application is wider now.
