Description

Solid-state chemical fertilizer is pricked cave and is applied industry combined mechanism with note

Technical field

The invention belongs to agricultural machinery, relates generally to a kind of solid-state chemical fertilizer note and executes working rig Structure.

Background technology

Due to the solid-state chemical fertilizer method of spreading manuer in holes have raising chemical fertilizer utilization ratio, reduce chemical fertilizer loss, Reducing the feature of fertilising cost, the method starts to promote in Maize at Seedling Stage intertillage topdressing operation Use.But, there is structure complexity, overall dimensions relatively in existing solid-state chemical fertilizer hole-application machine structure Greatly, fertilising is the most poor, seedling-damaging ratio is higher problem, therefore research and develop the solid state of new construction Fertilizer spread manuer in holes mechanism be current agricultural production operation in the urgent need to.

Summary of the invention

The purpose of the invention is aiming at the problem that above-mentioned prior art exists, in conjunction with agriculture Being actually needed of industry production operation, the solid-state chemical fertilizer of a kind of new construction of research design pricks cave and note Apply industry combined mechanism, reach compact overall structure, prick cave with fertilising operation synchronicity good, Fertilising precision is high, use the purpose reliable, operation fault is few.

The purpose of the invention is achieved in that on left shell half body fastening is fixedly mounted with right half Housing, constitutes in described left shell half body with right half shell and pricks cave plunger shaft and defeated fertile chamber, institute Stating defeated fertile bottom, chamber to be interconnected with pricking plunger shaft following side, cave, pricking cave piston can be the most axial Being fitted in the plunger shaft of bundle cave, in described left shell half body and right half shell opposing sidewalls of movement The upper piston anti-rotating slideway gap offering above-below direction respectively；Described left shell half body is fixedly mounted with External splines set, is arranged on external splines set trepanning by needle bearing by rotating for spline mandrel In, end, described spline mandrel side is fixedly mounted with rocking arm, connecting rod inserting is on right half-shell side In the through hole slideway offered on wall, the outer end of described connecting rod is hinged with rocking arm, described company The inner end portion of bar is hinged with pricking cave piston by bearing pin, and the both side ends of described bearing pin is respectively In inserting piston anti-rotating slideway gap in left and right half shell；Can turn in gear housing Dynamic installation central gear, idler gear and planetary gear, described idler gear respectively with too Sun gear and planetary gear engagement；Described planetary gear is fixedly mounted with external splines set, described spline Secure fit in the spline endoporus being fitted on gear housing is inserted in the other end of mandrel, extremely This constitutes solid-state chemical fertilizer bundle cave and applies industry combined mechanism with note.

The invention uses central gear epicyclic train to drive bundle cave to mate to fertilize with note Linkage integrated machine structure, completes to prick cave and Tong Bu works continuously with solid-state chemical fertilizer of spreading manuer in holes, have structure Novel in design, rationally, overall dimensions is compact, working performance is high, operation quality is good, operation Reliably, the feature that fault is few, seedling-damaging ratio is low is used.

Detailed description of the invention

Below in conjunction with the accompanying drawings the invention embodiment is described in detail.A kind of solid-state Chemical fertilizer is pricked cave and is applied industry combined mechanism with note, fastens and be fixedly mounted with right half shell on left shell half body 8 1, constitute in described left shell half body 8 with right half shell 1 and prick cave plunger shaft 14 and defeated fertile chamber 13, described defeated fertile bottom, chamber 13 is interconnected with pricking plunger shaft 14 following side, cave, pricks cave and lives What plug 2 can move axially up and down is fitted in bundle cave plunger shaft 14, at described left shell half body 8 With the piston anti-rotating slideway gap 17 offering above-below direction in right half shell 1 opposing sidewalls respectively； Described left shell half body 8 is fixedly mounted with external splines set 7, by needle bearing 6 by spline mandrel 5 The rotating external splines that is arranged on overlaps in 7 trepannings, on described spline mandrel 5 one side end It is fixedly mounted with Rocker arm 4, in the through hole slideway 15 that connecting rod 3 inserting is offered on right half shell 1 sidewall, The outer end of described connecting rod 3 is hinged with Rocker arm 4, and the inner end portion of described connecting rod 3 passes through pin Axle 16 is hinged with pricking cave piston 2, the inserting respectively of the both side ends of described bearing pin 16 left, In piston anti-rotating slideway gap 17 in right half shell 8,1；Can turn in gear housing 12 Dynamic installation central gear 9, idler gear 11 and planetary gear 10, described idler gear 11 engage with central gear 9 and planetary gear 10 respectively；Described planetary gear 10 and outer flower Key set 7 is fixedly mounted with, and the other end of described spline mandrel 5 is inserted and is fitted on gear housing 12 Spline endoporus in secure fit.
