Abstract
The utility model discloses a spring friction type one-way transmission mechanism for a seeder unit of an oilseed rape sowing machine. The mechanism comprises a seeder unit driving shaft, a rack, a spring, a stop pin and a seeder unit driving wheel, and is characterized in that the seeder unit driving shaft is arranged on the rack, and can freely rotate; the seeder unit driving wheel capable of freely rotating and the spring are arranged on the seeder unit driving shaft; the fixed stop pin is arranged on the edge of the seeder unit driving wheel; the internal diameter of the spring is slightly smaller than the external diameter of the seeder unit driving shaft; the spring is pre-pressed and sleeved on the outer circle of the seeder unit driving shaft; one end of the spring is a free end, and the other end of the spring contacts with the stop pin; when power is forwards input, the internal diameter of the spring is tightened, and the seeder unit driving shaft is driven to rotate along with the seeder unit driving wheel under driving of the spring; when the power is backwards input, the internal diameter of the spring is increased, the spring and the seeder unit driving wheel idly rotate on the seeder unit driving shaft, and the seeder unit driving shaft stops rotating. The mechanism is simple in structure and reliable in operation.
Description
Technical field
The utility model 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, in addition existing rape seeding machine seeding unit all adopts land wheel or power take-off directly to drive, when complete machine is turned in field or when other reasons occurs of short duration falling back, if can not excising in time, seeding unit power will there will be reversing, during seeding unit reversing, some work parts will make rape kind flattening or crowded rotten, cause and after planting occur shoot-breaking phenomenon.For some, only allow the seeding unit of one-way movement, also can damage workpiece.So rape seeding machine seeding unit adopts unidirectional input power necessary.
Utility model content
The purpose of this utility model 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, 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 utility model is: spring friction-type one-way driving mechanism for a kind of rape seeding machine seeding unit of manufacturing according to such scheme, when power forward is inputted, the driving shaft of seeding unit rotates with seeding unit driving wheel, when power reverse is inputted, the driving shaft of seeding unit stops the rotation, and seeding unit driving wheel dallies on seeding unit driving shaft.This mechanism structure is simple, operation is reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the utility model.
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 utility model is described in further detail.
As shown in Figure 1, spring friction-type one-way driving mechanism for a kind of rape seeding machine seeding unit of the utility model, 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 is during according to direction rotation shown in Fig. 1, fixedly be located at this backing pin of taking turns edge 4 and will drive one 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, by being fixedly located at one end that this backing pin of taking turns edge 4 drives springs 3 to be in contact with it, counter-rotate 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.
