Description

Dibbler for maize seed fertilizer

The utility model relates to the general agricultural machinery of sowing, fertilising, particularly adapts to the kind of interplanting corn, fertile planter.

There is a kind of corn planter of little four-wheel traction in China at present, and it is fit to large tracts of land sowing corn uses, and interplanting corn is improper.The also single file of the manpower of promising interplanting corn or animal-drawn, duplicate rows planter, the type of drive of these planters is four bar linkages basically, or the type of drive of the two places wheel drive fertilization wheel axis of frame both sides and sowing wheel shaft, four bar linkages are difficult for realizing clutch, make loom when breaking, as long as land wheel rotates, fertilising is taken turns and seeding wheel must rotate, seed, fertilizer just constantly fall, have only complete machine is mentioned, just can address the above problem, simultaneously this type of drive spacing in the rows is adjusted difficulty, brings a lot of inconvenience to use.Two places, frame both sides wheel drive structure makes that seed manure spacing ground is higher, and defeated kind, fertile pipe are longer, plants, fertile freely to fall distance also longer, and it is inhomogeneous to cause spacing in the rows to become different.

It is simple in structure that the purpose of this utility model provides a kind of type of drive, easily realizes clutch, easily adjusts spacing in the rows, kind, the fertile planter of the interplanting corn of in light weight, easy to operate a kind of suitable people, animal power traction.

Realize that scheme of the present utility model is: fixed installation seeding and fertilizing case on frame, separate with dividing plate before and after the seeding and fertilizing case, first half is a fertilizing box, latter half of is Seeding box, in the fertilizing box bottom fertilising wheel is arranged, the fertilising wheel is contained on the fertilization wheel axis, the other fertilizer scraper that is equipped with of fertilising wheel, in the Seeding box bottom seeding wheel is arranged, seeding wheel is contained on the sowing wheel shaft, the other installation of seeding wheel scraped kind of a sheet, fertilization wheel axis, the sowing wheel shaft is installed on the frame sill by axle sleeve, at fertilizer scraper, scrape furrower is installed respectively under the housiung separator under kind of the sheet, defertilizing tube and discharging tube, be installed with trailing bar and press wheel before and after on discharging tube afer bay sill, characteristics are that driving wheel adopts preceding land wheel, preceding land wheel is fixedly mounted on the tooth fork type clutch, clutch is movably arranged on the preceding land axle by axle sleeve, the clutch shifter end is fixedlyed connected with the preceding sprocket wheel be movably arranged on preceding land axle by axle sleeve on, clutch operating lever is fixedlyed connected by rod member with the clutch shifter end, preceding sprocket wheel, fertilization wheel axis, the sowing wheel shaft is by being installed in the intermediate chain wheel on the fertilization wheel axis, fertilising sprocket wheel and be installed in sowing sprocket wheel and the chain drive sowed on the wheel shaft and be connected.

By animal power or manpower traction preceding land wheel is rotated, the rotation of preceding land wheel and then rotates the preceding sprocket wheel that is installed on the land axle by tooth fork type clutch mechanism again, thereby fertilising sprocket rotation by the chain drive connection, the fertilising sprocket rotation drives fertilization wheel axis and rotates fertilization wheel axis rotation passing through again chain, the transmission of sowing sprocket wheel is rotated the sowing wheel shaft, fertilization wheel axis, the rotation of sowing wheel shaft, feasible fixed installation fertilising wheel thereon, seeding wheel rotates, their rotation, make sowing, fertilizer in the fertilizing box and seed are along the fertilising wheel, fertilizer scraper and seeding wheel, scrape kind of sheet and defertilizing tube, discharging tube successively falls into the disposable kind of finishing of trench that furrower is left, fatbits is broadcast task, by replacing the sprocket wheel of different-diameter, land wheel before making, fertilization wheel axis, the gearratio of sowing wheel shaft obtains changing, thereby reached the purpose that changes the sowing spacing in the rows, if tooth fork type clutch separation, though land wheel rotates, the fertilising wheel, seeding wheel does not rotate.

Advantage of the present utility model is that this machine adopts the type of drive of preceding land wheel, tooth fork type clutch, sprocket wheel, chain drive fertilising wheel, seeding wheel, simple in structure, can carry out quantitatively, locate, apply fertilizer, sow, realize according to preceding land wheel travel distance kind, nutriment in a fertilizer layer branch broadcast purpose, can adjust spacing in the rows and line-spacing effectively, volume is little, in light weight, easy to operate, is a kind of comparatively ideal corn kind, the fertile planter that uses when being fit to farmers''s interplanting corn.
