Abstract
The invention discloses a spring friction type one-way transmission mechanism used for a seed metering device of a rape seeder. The spring friction type one-way transmission mechanism comprises a driving shaft of the seed metering device, a rack, a spring, a stop pin and a driving wheel of the seed metering device. The spring friction type one-way transmission mechanism is characterized in that the rack is provided with the driving shaft of the seed metering device, which can rotate freely; the driving shaft of the seed metering device is provided with the driving wheel of the seed metering device, which can rotate freely, and the spring; the fixed stop pin is arranged at the rim of the driving wheel of the seed metering device, the inner diameter of the spring is slightly smaller than the outer diameter of the driving shaft of the seed metering device, the spring is pre-pressed and tightly sheathed on an excircle of the driving shaft of the seed metering device, one end of the spring is a free end, and the other end of the spring is in contact with the stop pin. When power is input from a positive direction, the inner diameter of the spring is tightened, and the driving shaft of the seed metering device is driven by the spring to rotate along with the driving wheel of the seed metering device; when the power is input from a reverse direction, the inner diameter of the spring is increased, the spring rotates along with the driving wheel of the seed metering device on the driving shaft of the seed metering device, and the driving shaft of the seed metering device stops rotating. The spring friction type one-way transmission mechanism is simple in structure and reliable to operate.
Description
Technical field
The present invention is rape seeding machine seeding unit parts, belongs to agricultural mechanical field, is specifically related to spring friction-type one-way driving mechanism for a kind of rape seeding machine seeding unit.
Background technology
Along with the fast development of Tendency of Agricultural Machinery in China, the development of domestic various novel rape seeding machineries emerges in an endless stream.But because little, the anti-extrusion performance of rapeseed seeds grain is poor, existing rape seeding machine seeding unit all adopts land wheel or power take-off directly to drive in addition, when complete machine, in field, turn or other reasons while of short duration falling back occurring, if can not excising in time, seeding unit power will there will be reversing, during the seeding unit reversing, the some work parts will make rape kind flattening or crowded rotten, cause and shoot-breaking phenomenon after planting occurs.Only allow the seeding unit of one-way movement for some, also can damage workpiece.So the rape seeding machine seeding unit adopts unidirectional input power necessary.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, propose a kind of simple in structure, operate spring friction-type one-way driving mechanism for reliable a kind of rape seeding machine seeding unit.
The technical scheme that realizes above-mentioned purpose is: spring friction-type one-way driving mechanism for a kind of rape seeding machine seeding unit, it comprises seeding unit driving shaft, frame, spring, backing pin and seeding unit driving wheel.It is characterized in that: described frame is provided with the seeding unit driving shaft that can rotate freely, the seeding unit driving shaft is provided with seeding unit driving wheel and the spring that can rotate freely, seeding unit driving wheel edge is provided with fixing backing pin, spring inside diameter is slightly less than the external diameter of seeding unit driving shaft, pre-pressing is enclosed within on the cylindrical of seeding unit driving shaft, one end of spring is free end, and the other end contacts with backing pin.
Effect of the present invention is: spring friction-type one-way driving mechanism for a kind of rape seeding machine seeding unit of manufacturing according to such scheme, when the power forward is inputted, the driving shaft of seeding unit rotates with the seeding unit driving wheel, when power reverse is inputted, the driving shaft of seeding unit stops the rotation, and the seeding unit driving wheel dallies on the seeding unit driving shaft.This mechanism structure is simple, operation is reliable.
The accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the invention.
In figure: 1. seeding unit driving shaft, 2. frame, 3. spring, 4. backing pin, 5. seeding unit driving wheel.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, spring friction-type one-way driving mechanism for a kind of rape seeding machine seeding unit of the present invention, it comprises seeding unit driving shaft 1, frame 2, spring 3, backing pin 4 and seeding unit driving wheel 5.It is characterized in that: described frame 2 is provided with the seeding unit driving shaft 1 that can rotate freely, seeding unit driving shaft 1 is provided with seeding unit driving wheel 5 and the spring 3 that can rotate freely, seeding unit driving wheel 5 edges are provided with fixing backing pin 4, spring 3 internal diameters are slightly less than the external diameter of seeding unit driving shaft 1, pre-pressing is enclosed within on the cylindrical of seeding unit driving shaft 1, one end of spring 3 is free end, and the other end contacts with backing pin.
In the course of work, when seeding unit driving wheel 5 during according to direction rotation shown in Fig. 1, fixedly be located at this backing pin of taking turns edge 4 and will drive the end rotation that spring 3 is in contact with it, spring 3 is inwardly tightened up, to increase with the frictional force of seeding unit driving shaft 1 and to drive its rotation.Otherwise, when seeding unit driving wheel 5 counter-rotates according to direction shown in Fig. 1, seeding unit driving wheel 5 first sky on seeding unit driving shaft 1 circles, drive by fixedly being located at this backing pin of taking turns edge 4 the end reverse rotation that spring 3 is in contact with it again, spring 3 internal diameters are increased, lose with the frictional force of seeding unit driving shaft 1 and with the spring 3 one oppositely idle running on seeding unit driving shaft 1 that coexists, thereby realize single-direction transmission.
