Description
Technical field
The present invention relates to rice transplanter mechanical field, particularly relate to a kind of rice transplanter transplanting mechanism of transplanting for hybrid paddy rice maternal breeding.
Background technology
Show through experimental study at present, it is about 170mm that the hybrid paddy rice maternal breeding in some area transplants required line-spacing, and the line-spacing of rice transplanter mostly is 300mm or 240mm at present, cannot meet the hybrid paddy rice production of hybrid seeds requirement in these areas; And existing maternal transplanting method mostly is artificial transplanting, its operation is loaded down with trivial details, work consuming amount is large, man-hour is long, labour intensity is large, production cost is high, and can affect the seed output and quality of seed.
Summary of the invention
The object of the invention is the deficiency in order to make up prior art, provide a kind of rice transplanter transplanting mechanism of transplanting for hybrid paddy rice maternal breeding, solve existing hybrid paddy rice hybrid seeding great majority and use artificial backward production method of transplanting, its labour intensity is large, production cost is high, inefficiency; Simultaneously the line-spacing of rice transplanter mostly is 300mm or 240mm, and the hybrid paddy rice production of hybrid seeds that can not meet this area such as to require at the problem.
The present invention is achieved through the following technical solutions:
A kind of rice transplanter transplanting mechanism of transplanting for hybrid paddy rice maternal breeding, it is characterized in that: include support arm, sprocket shaft, planting arm, crank, rocking bar, seedling pawl, cam, shift fork, seedling pushing device, described support arm front end is provided with sprocket shaft, the two ends of described sprocket shaft are installed with crank respectively, the end winding support of described crank is provided with planting arm, described planting arm rear end is connected with rocking bar, described rocking bar is rotatably installed on the support on support arm front end face, described planting arm front end is provided with seedling pawl and seedling pushing device, described seedling pushing device is positioned at the middle part of seedling pawl, and driven by cam and shift fork, what described cam and shift fork cooperatively interacted is installed in planting arm, pilot hole is provided with in planting arm above described shift fork, spring is provided with in described pilot hole, described lower spring end withstands on shift fork.
Described sprocket shaft is installed with sprocket wheel, and described sprocket wheel is connected with power transmission by the chain in support arm.
Described support fixed installation is with on the front end face of support arm, and its Y-shaped structure, its both sides divide the end part rotating shaft of other fixed axis to be provided with axle sleeve, and described axle sleeve is fixedly installed in the rearward end of rocking bar.
Described seedling pushing device includes the body of rod, and described body of rod rearward end is fixedly connected with shift fork, and described lever front end face is provided with push pedal, in the gap of described push pedal between seedling pawl.
Described shift fork is a body of rod, and end is provided with the arc surface with cam engagement thereafter, and described cam rotates and is installed in planting arm, and the leading section of described shift fork is fixedly connected with seedling pushing device.
Its principle is: crank is fixed on sprocket shaft, and power transmission is to sprocket wheel, and drive crank to move in a circle, rocking bar does the reciprocally swinging of certain angle, and planting arm does the compound movement in plane.When seedling pawl inserts face, field, cam is separated with shift fork and contacts, and under the effect pushing away seedling spring, promotes seedling pushing device make rice shoot depart from seedling pawl and planting in field.As: the line-spacing of support arm planting arms on both sides is designed to 170mm, shortens 130mm, meet instructions for use than the line-spacing of common seedling transplanter.
Advantage of the present invention is:
Reasonable in design of the present invention, design the planting arm line-spacing of its support arm both sides, the line-spacing requirement that these areas are transplanted female parent can be met, the complete machine of this mechanism is single wheel riding type, therefore, it is possible to greatly reduce labour intensity, improve rice transplanting efficiency, save farming season, reduce production cost, and solve the problems such as the in short supply and seed quality of labour is unstable.

Detailed description of the invention
See accompanying drawing, a kind of rice transplanter transplanting mechanism of transplanting for hybrid paddy rice maternal breeding, include support arm 3, sprocket shaft 1, planting arm 5, crank 2, rocking bar 4, seedling pawl 6, cam 8, shift fork 10, seedling pushing device 7, support arm 3 front end is provided with sprocket shaft 1, the two ends of sprocket shaft 1 are installed with crank 2 respectively, the end winding support of crank 2 is provided with planting arm 5, planting arm 5 rear end is connected with rocking bar 4, rocking bar 4 is rotatably installed on the support on support arm 3 front end face, planting arm 5 front end is provided with seedling pawl 6 and seedling pushing device 7, seedling pushing device 7 is positioned at the middle part of seedling pawl 6, and driven by cam 8 and shift fork 10, what cam 8 and shift fork 10 cooperatively interacted is installed in planting arm 5, pilot hole is provided with in planting arm 5 above shift fork 10, spring 9 is provided with in pilot hole, spring 9 lower end withstands on shift fork 10, sprocket shaft 1 is installed with sprocket wheel, and sprocket wheel is connected with power transmission by the chain in support arm 3, on the front end face of support fixed installation and support arm 3, its Y-shaped structure, its both sides divide the end part rotating shaft of other fixed axis to be provided with axle sleeve, and axle sleeve is fixedly installed in the rearward end of rocking bar 4, seedling pushing device 7 includes the body of rod, and body of rod rearward end is fixedly connected with shift fork 10, and lever front end face is provided with push pedal, in the gap of push pedal between seedling pawl 6, shift fork 10 is a body of rod, and end is provided with the arc surface coordinated with cam 8 thereafter, and cam 8 rotates and is installed in planting arm 5, and the leading section of shift fork 10 is fixedly connected with seedling pushing device 7.
Power is by the chain drive in support arm 3 to sprocket shaft 1, and drive crank 2 to move in a circle, rocking bar 4 does reciprocally swinging, and planting arm 5 does the compound movement in plane.Power, except passing to transplanting mechanism, also will pass to seedling case, makes seedling case make bilateral reciprocation along guide rail.Be insert face, field the seedling pawl 6 of a component to enter the rice shoot that seedling fetching hole 13 on guide rail 12 cuts on seedling case 11 by desired trajectory (i.e. coupler-point curve) after with planting arm 5 consolidation.Disengaged by cam 8 and shift fork 10 when seedling pawl 6 inserts face, field, under the pressure effect pushing away seedling spring 9, promoting seedling pushing device 7 makes rice shoot depart from seedling pawl 6 and plant in field, again contacting afterwards along with cam 8 and shift fork 10, seedling pushing device 7 turns back to again the position before separation, and transplanting mechanism carries out work by this turning course gone round and begun again.
