Specific implementation mode
Embodiment 1:
A kind of pneumatic seeder switching device, including three-way body 4, cylinder 15 (existing Standard Cylinder), ball link,
Flange connector, bearing, leading screw 9, three-way body fixing shell 5, valve block, transmission shaft, solenoid directional control valve.
Solenoid directional control valve 4 is connected with the left and right chamber of Standard Cylinder 15 respectively by tracheae 1 and tracheae 23, manipulates electromagnetism
Reversal valve makes pneumatic power source pass through tracheae and connects with difference cylinder chamber, and Telescopic-cylinder bar is made to carry out the movement of different directions;Gas
It is threadedly coupled between cylinder telescopic rod (14) and ball link 3 13, ball link 3 13, flange connector 2 12 and flange
It is attached respectively with axis pin and split pin between connector 2 12, ball link 2 10, ball link 2 10, leading screw 9
Between be threadedly coupled respectively between leading screw 9, ball link 1, between ball link 1, flange connector 1
It is attached with axis pin and split pin, passing power is played the role of in the connection between each section;One end of flange connector 1
It is carried out respectively with bearing 1 and bearing 2 11 with transmission shaft 1 and transmission shaft 2 18 with the through-hole among flange connector 2 12
Connection, bearing connection play the role of reduce connector between wear and play connection three-way body 4 and three-way body fixing shell 5 work
With;Valve block 1 and valve block 2 19 is respectively welded on transmission shaft 1 and transmission shaft 2 18, is connected between valve block and transmission shaft
One entirety rotates simultaneously.
The valve block 1 and valve block 2 19 is vertically arranged, and two valve blocks spatially intersect in 90 °.
4 left and right sides of the three-way body is set there are two air inlet, be located at transmission shaft 1 and 2 18 bottom end of transmission shaft it
Between three-way body bottom set there are one gas outlet;Gas outlet is connect with vacuum blower, and two air inlets are broadcast with existing cotton respectively
Useless kind of the retracting device carried in kind machine connects to form clear kind and seeding access with feed mechanism for seed;By manipulating the electromagnetic switch
Valve 4 completes seeding or clear kind of work.
In the present invention, the Standard Cylinder is a kind of pneumatic execution that the pressure energy of compressed gas is converted to mechanical energy
Element, effect is the linear motion that the air pressure for generating air pump is converted into Telescopic-cylinder bar, real to make valve block rotate
The switching of existing seeding and clear kind of access.
The ball link three is threaded hole, can carry out screw thread company with screwed Telescopic-cylinder bar and leading screw
It connects, two components of threaded connection is made to be convenient to mount and dismount.
The leading screw both ends carry oppositely oriented screw thread, it can be achieved that the ball link 1 and spherical connection
Distance elongates or shortens between part 2 10, to realize the minor rotation of valve block 1 and valve block 2 19, reinforces two valve blocks
To the seal of two paths;Leading screw 9 plays the connection function of connecting rod, passing power and movement.
When seeding, vacuum blower is opened, opens the air pump being connected with solenoid directional control valve 2, solenoid directional control valve 2 is powered on
Afterwards, the air stream that air pump generates enters Standard Cylinder 15, pushes piston, and Telescopic-cylinder bar 14 is made to move, and drives flange connector
2 12 and the rotation with the matched transmission shaft of in-between through-hole 2 18, realize that seeding is logical in 2 19 pairs of three-way bodies 4 of valve block on axis
The opening on road, i.e. vacuum blower are connected with seeding access, and sowing port end is made to generate vacuum degree, are carried out using negative-pressure adsorption seed
Seeding;The rotation for driving flange connector 1 while flange connector 2 12 moves by the transmission of leading screw 9 makes to carry valve
The transmission shaft 1 of piece 1 rotates, and realizes that the closing of clear kind of access in three-way body 4, the negative pressure of clear kind of access end disappear, clearly
Kind operation stops.
At clear kind, 2 commutation work of solenoid directional control valve, Telescopic-cylinder bar 14 movement band one 17 turns of moving valve plate 2 19 and valve block
It is dynamic, so that seeding path blockade, the sowing port negative pressure of seeding access end is disappeared, seed discharging operation stops, while clear kind of access is opened,
I.e. vacuum blower is connected with clear kind of access, and the vacuum degree generated using vacuum blower makes clear kind of access end generate negative pressure, will arrange
Useless kind in kind cleaning device is adsorbed onto useless kind and deposits in kind of room, carries out useless kind of collection.
The present invention can realize the switching of two kinds of accesses under given conditions, realize reasonable connection, easy to operate, have compared with
Good practicability and prospect of the application.
The above is only the preferred embodiment of the application, is skilled artisans appreciate that or realizing this Shen
Please.This specific example is only explanation of the invention, is not limitation of the present invention, and the technical staff of one's respective area is reading
After complete this specification, can no creative contribution be made to this example as needed and changed, as long as but in the power of the present invention
