Description
Technical field
The invention provides a kind of sowing spacing in the rows stepless regulator, belong to agricultural machinery technological field.
Background technology
The soil types that China ploughs is varied, and the planting patterns difference of various places crop, the seeding quantity of same crop require also different, and this just requires the seeding quantity of sower to regulate according to demand.Generally the rotating ratio of the seed plate by changing the sower seeding unit and the sower land wheel seeding quantity that can regulate sower is regulated the sowing spacing in the rows exactly for the bunch planting crop.At present, using more is gear-shift mechanism conversion gear adjuster, but can only have level to regulate to spacing in the rows.The spacing in the rows adjusting device that has can be to the spacing in the rows step-less adjustment, but brings the defective of spacing in the rows fluctuation simultaneously.Though the spacing in the rows regulating system of rice transplanter can need hydraulic system to the spacing in the rows step-less adjustment, and is complicated, only is applied on the rice transplanter.
Summary of the invention
The purpose of this invention is to provide a kind of sowing spacing in the rows stepless regulator that can overcome above-mentioned defective, simple in structure, reliable operation, simple to operation, the sower that is applicable to multiple seeding unit.
Its technology contents is: a kind of sowing spacing in the rows stepless regulator, comprise the inner conical surface friction pulley, the male cone (strobilus masculinus) friction pulley, driven sprocket, drive sprocket, regulating wheel, inner conical surface friction pulley wherein, the male cone (strobilus masculinus) friction pulley, drive sprocket, the axis of regulating wheel is parallel, the inner conical surface friction pulley is installed in delivery plate shaft one end of sower by feather key, and leave the gap between inner conical surface friction pulley endoporus and the delivery plate shaft, the male cone (strobilus masculinus) friction pulley, driven sprocket is separately fixed at the both sides of axle, drive sprocket is fixedly mounted on the land axle of sower, it is characterized in that: the close inner conical surface friction pulley of the end that male cone (strobilus masculinus) friction pulley radius is little, the conical surface of male cone (strobilus masculinus) friction pulley equates with the tapering of the conical surface of inner conical surface friction pulley and fits driven sprocket mutually, drive sprocket, regulating wheel connects through a chain.
Described sowing spacing in the rows stepless regulator is adjusted nut and is screwed on the screw thread that is arranged on the delivery plate shaft middle part, and the conical surface of inner conical surface friction pulley is adjusted nut dorsad and is installed in delivery plate shaft one end, adjusts suit one spring between nut and the inner conical surface friction pulley.
Described sowing spacing in the rows stepless regulator, the middle part that two ends are installed with the axle of male cone (strobilus masculinus) friction pulley and driven sprocket is supported on the bearing bracket stand, bearing bracket stand is provided with axis normal in the nut of axis, the end that the middle part is supported on the leading screw on the sowing frame is screwed in the nut from the abaxial end of nut, and the other end is installed a handwheel.
Its operation principle is: the sower land wheel drives the male cone (strobilus masculinus) friction pulley by the chain transmission and rotates, and then the frictional drive of passing through male cone (strobilus masculinus) friction pulley and inner conical surface friction pulley drives the seed plate rotation of sower seeding unit, change the gearratio between male cone (strobilus masculinus) friction pulley and the inner conical surface friction pulley, can change the seed plate of sower seeding unit and the rotating ratio between the sower land wheel, thereby reach the purpose of regulating the sowing spacing in the rows, during concrete operations, unclamp regulating wheel earlier, rotate handwheel, pass through leading screw, nut regulating shaft bolster is with respect to the lateral attitude between the delivery plate shaft, namely the axle and delivery plate shaft between distance, thereby changed the position of male cone (strobilus masculinus) friction pulley and inner conical surface friction pulley joint place, reach the purpose that changes gearratio between male cone (strobilus masculinus) friction pulley and the inner conical surface friction pulley, then, rotated the nut on the delivery plate shaft, be pressed on the conical surface of male cone (strobilus masculinus) friction pulley by the conical surface of spring with the inner conical surface friction pulley, fixed tensioning is taken turns again at last, and the sowing spacing in the rows is regulated and finished, and sower can be started working.
The present invention compared with prior art, its advantage is: rotate the radius that handwheel can continuously change male cone (strobilus masculinus) friction pulley and inner conical surface friction pulley joint place, the seed plate of sower and the gearratio between the sower land wheel are continuously changed, thereby realize the step-less adjustment of planting with sowing machine spacing in the rows; Because the power that the sower seed plate consumes is generally all less, the sliding ratio of frictional drive is less between male cone (strobilus masculinus) friction pulley and the inner conical surface friction pulley, and the uniformity of spacing in the rows is not had to influence substantially; Simple in structure, reliable operation, simple to operation are applicable to the sower of multiple seeding unit.
