Description
Technical field
The utility model belongs to agricultural machinery, relates generally to the seeding unit seeding speed regulating mechanism on a kind of seeding machinary.
Background technology
In order to satisfy and the agriculture requirement that adapts to Different Crop kind, different seeding quantitys, all need the seeding unit seeding rotating speed on the seeding machinary is regulated, to enlarge facility operation adaptive capacity.Traditional speed change control method is to change land axle sprocket wheel, jackshaft sprocket wheel and feed shaft sprocket wheel, changes its gearratio and realizes the speed change adjusting, and the speed change adjusting is complicated, operating efficiency is low, mostly spare part is its distinct issues.For solving and overcoming the problems referred to above, in recent years, multiple mechanical arrangements for speed regulation begin on seeding machinary on probation, but ubiquity complex structure, the speed change gear is few, spatial configuration is not compact, variable speed operation is inconvenient, manufacturing cost is higher defective.
Summary of the invention
The purpose of this utility model is exactly the defective that exists at above-mentioned prior art, design provides a kind of seeding unit seeding gear of new construction, reaches simplified structure, appearance and size compactness, transmission of power balanced and reasonable, many, easy and simple to handle, the reliable purpose of operation of speed change gear.
Basic design of the present utility model is, seeding unit seeding gear comprises jackshaft, and what jackshaft and power take-off were parallel to each other is fitted on the gearbox body, and power take-off both sides rotatably support is inserted in the fixedly connected plate hole of left and right side; Install left drive sprocket, speed change cone pulley and right drive sprocket on power take-off successively, wherein the speed change cone pulley is positioned at the gearbox body cavity, and left drive sprocket and right drive sprocket lay respectively at the left hand external and the right hand external of gearbox body; Driving wheel can move axially, circumferentially and being installed on the jackshaft of radial location, the gear train frame that has idle wheel can move axially and be fitted on the jackshaft rotationally, idle wheel and driving wheel often mesh, idle wheel meshes successively with the speed change cone pulley or separates; Gear change hand lever fits on the gear train frame admittedly, is provided with speed change gear groove on the gearbox body upper wall, and gear change hand lever is configured in position and lock cooperation successively in the speed change gear groove.
The speed changing structure that driving wheel on the utility model employing jackshaft and the speed change cone pulley on the power take-off mesh is successively finished seeding unit feed shaft rotation speed change, realize that seeding quantity and spacing in the rows regulate, have simple and compact for structure, transmission of power is balanced, easy to operate, operation reliable, many, the advantage of wide range of application of speed change gear.
