Abstract
The utility model discloses a stepless speed changing device of a double row transplanter which belongs to the speed changing device. The structure of the utility model comprises a motor crank shaft and a gear box shaft; the motor crank shaft is provided with a drive belt pulley; an eccentric steel pole is arranged between one drive belt pulley with single side of the drive belt pulley and a compression plate; the gear box shaft is provided with a driven belt pulley; a pressed spring is arranged between one driven belt pulley with single side of the driven belt pulley and a spring stopping seat; the drive belt pulley and the driven belt pulley are connected by the belt. Compared with the prior art, the stepless speed changing device of a double row transplanter of the utility model has the advantages of rational design, simple structure, convenient operation, adjustable speed, high working efficiency and so on.
Description
Technical field
The utility model relates to a kind of speed change gear of farm machinery, specifically the stepless speed changes devices in the twin-row transplanter.
Background technique
The paddy rice twin-row transplanter is hand with manpower at present is power source.Not only farming personnel labor intensity of this mode of operation is big, and inefficiency.The machinery that has now adopts put-put to do power source, though people's working strength improve,, after adopting put-put to do power source, the bad control of the speed of rice transplanting is if operate bad, can cause certain rice shoot loss, delay normally carrying out of transplanting work.
Summary of the invention
Technical assignment of the present utility model is at above deficiency, and the stepless speed changes devices in the twin-row transplanter of a kind of speed governing flexibly, high working efficiency is provided.
The technological scheme that its technical problem that solves the utility model adopts is: engine crankshaft is provided with drive pulley, be provided with centrifugal steel column between one monolateral belt pulley of active of drive pulley and the pressurization disk, gear-box axle is provided with negative pulley wheel, be provided with stage clip between one passive monolateral belt pulley of negative pulley wheel and the spring block seat, drive pulley is connected by belt with negative pulley wheel.
The monolateral belt pulley of active that centrifugal steel column is housed is installed togather by lining and the monolateral belt pulley of another active; Pressurization disk is fixedly mounted on the engine crankshaft by nut; The belt that connects drive pulley and negative pulley wheel is the vee belt.
Raising by the engine crankshaft rotating speed, the centrifugal force of centrifugal steel column increases, simultaneously under the effect of pressurization disk, promote the monolateral belt pulley of active and move inwards, make the initiatively effective diameter increase of monolateral belt pulley, by the tension force of vee belt, force the stage clip compression, passive monolateral belt pulley effective diameter reduces, and rice transplanting speed improves, otherwise reduces.The speed of transplanter rice transplanting speed depends on the size of throttle, makes the complete machine operation very easy.
Stepless speed changes devices in the twin-row transplanter of the present utility model is compared with prior art, has characteristics such as reasonable in design, simple in structure, easy to use, speed governing flexibly, working efficiency height.
