Clearance meshing involute gear anti-blocking fertilizer dispenser belongs to agricultural machinery: the upper and lower ends of the fertilizer dispenser box are respectively provided with the fertilizer inlet and outlet, and the main and driven flange gear shafts in the form of intermeshing are respectively fixed with the main and driven involute fertilizer dispenser gears through the inner hexagonal bolts, and the main and driven flange gear shafts are rotated and connected with the fertilizer dispenser box. The main and the driven involute fertilizer feeding gears are located on the left and right sides of the fertilizer feeding box respectively. The adjacent teeth of the main and the driven involute fertilizer feeding gears formed by pairs of involute tooth surfaces are in the shape of interpolation clearance meshing. The machine crushes the agglomerated fertilizer at the entrance of the fertilizer box through the meshing movement between the ridge and the groove of the main and driven involute fertilizer feeding gears and the rubbing action between the adjacent involute tooth surfaces, and moves the fine fertilizer along the fertilizer space between the ridge and the groove in successive alternation to the fertilizer feeding port to prevent blockage and adhesion. Design function. At the same time, the device has the characteristics of novel structure, simple and reasonable, reliable quality and strong applicability.
【技术实现步骤摘要】
间隙啮合渐开线齿轮防堵排肥器
本专利技术创造属于农业机械,主要涉及一种间隙啮合渐开线齿轮防堵排肥器。
技术介绍
目前,我国由于肥料的不合理施放,如施肥方式、施肥量及施肥精度等,造成土壤退化、肥力下降、耕层变浅及土壤板结等现象,不利于我国农业的可持续发展。外槽轮排肥器作为施肥作业机具的常用核心部件,虽因其适应性强、结构简单、排肥量稳定、调节方便及工作可靠等特点而被广泛应用,但当其针对粒径较小的粉状或结晶状肥料作业时,化肥由于吸湿和受压而出现结块现象,或者出现肥料粘结排肥轮凹槽的现象,而出现的施肥稳定性差,甚至出现排肥器堵塞,以致造成肥料漏排、施肥断条,严重影响施肥作业质量,致使作物因养分供应不足而影响正常生长,最终导致作物减产。因此,研究一种具有防堵、防粘结且排肥稳定的排肥器,具有重要的实际意义。
