Below, have the overall work process of the device for draining fluid of one embodiment of the invention of structure and the function of each parts as mentioned above with reference to each description of drawings.
Fig. 5 shows the schematic diagram of piston propradation shown in Figure 2, and Fig. 6 shows the schematic diagram of piston decline state shown in Figure 2.Fig. 7 a to Fig. 7 d briefly shows the schematic diagram of piston and nozzle relation according to the job order of the device for draining fluid of one embodiment of the invention.
The term of the concerned directions such as " left side " of using in the following description, " right side ", " top ", " bottom " is to give based on each accompanying drawing for convenient understanding.
At state shown in Figure 6, namely be arranged under the state of upper dead center T of groove 112 of the first cam part 110 that roller 240 on the link member 210 of drive portion 200 up and down reciprocatingly is positioned at cam mechanism 100, the lower end of the piston 440 of piston portion 400 is close to the base plate face of the inner space 520 of the block 510 of nozzle unit 500, and the notch portion 411 of piston 440 not corresponding with the inflow entrance 521 that is formed on block and exhaust port 522 (state of Fig. 7 d).
Fluid flows into process
Rotation based on the running shaft 101 of cam mechanism 100, the first cam part 110 is rotated thereupon, thus during the lower dead centre L in the roller 240 on the link member 210 that is arranged on drive portion 200 up and down reciprocatingly reaches the groove 112 of the first cam part 110 of cam mechanism 100, the right side of link member 210 (take Fig. 2 as benchmark) moves down the height difference that (rotation) is equivalent to upper dead center T and the lower dead centre L of the first cam part 110, on the contrary, centered by central shaft 215,216, (rotation) moves up in left side (being connected with dull and stereotyped 220).
Meanwhile, the flat board 220 that is connected with link member 210 that is make progress centered by the second hinge axis 222 (rotation) are mobile.So, when dull and stereotyped 220 move up, restored by the dull and stereotyped 220 interior springs 450 of shell 410 that are compressed in piston portion 400, based on the restoring force of spring 450, rotatingshaft 420 and the piston 440 of piston portion 400 move up thereupon.
In addition, above-mentioned steps carry out process, the second cam part 120 and first cam part 110 of cam mechanism 100 together rotate.At this, keep the second gear part 430 of the piston portion 400 of engagements to accept selectively the rotating force of the second cam part 120 with the first gear part 323 of the power transmission member 320 of power transfering part 300.
That is, the explanation of having carried out in the structure of relevant power transfering part 300 and work, based on the structure of the power transmission member 320 of the second cam part 120 of cam mechanism 100 and power transfering part 300, power transmission member 320 is repeatedly carried out and is rotated and stop.
At this, when the rotatingshaft 420 of piston portion 400 moved up, power transmission member 320 preferably was in halted state, and namely the rotatingshaft 420 of piston portion 400 does not rotate.
As mentioned above, rising along with the rotatingshaft 420 of piston portion 400, the notch portion 411 that is formed on piston 440 lower ends can be corresponding with the inflow entrance 521 of the block 510 that is formed on nozzle unit 500, and fluid flow into 520 li of the inner spaces (state of Fig. 5 and Fig. 7 a) of the block 510 that piston 440 is pulled out according to moving up thereupon.
Afterwards, even the first cam part 110 of cam mechanism 100 continues rotation, be arranged on the groove 112 that roller 240 on the link member 210 of drive portion 200 up and down reciprocatingly is positioned at dead point and lower dead centre on the first cam part 110 that connects cam mechanism 100, thereby notable change can not occur in the height of link member 210 and flat board 220.
But, rotation along with the power transmission member 320 of power transfering part 300, the rotatingshaft 420 of piston portion 400 of rotating force that receives second cam part (continue rotation) 120 of cam mechanism 100 can rotation, thereby the notch portion 411 that is formed on the piston 440 of piston portion 400 can be towards exhaust port 522 rotations (state of Fig. 7 b) on the block 510 that is formed on nozzle unit 500.
The fluid expulsion process
The first cam part 110 continuation rotations along with cam mechanism 100, up and down reciprocatingly the roller 240 on the link member 210 of drive portion 200 reaches the upper dead center T of the first cam part 110 of cam mechanism 100, this moment link member 210 right side (take Fig. 2 as benchmark) move up (rotation) be equivalent to the height difference of upper dead center T and the lower dead centre L of the first cam part 110, on the contrary, centered by central shaft 215,216, the left side moves down (rotation).
The flat board 220 that is connected with link member 210 that is (rotation) movement downwards centered by the second hinge axis 222.According to moving down of flat board 220, with rotatingshaft 420 declines of dull and stereotyped 220 contacted piston portions 400, meanwhile spring 450 is compressed in shell 410.
Carry out process in above-mentioned steps, the second cam part 120 and first cam part 110 of cam mechanism 100 are together rotated, but when the rotatingshaft 420 of piston portion 400 moved down, power transmission member 320 preferably was in halted state, and namely the rotatingshaft 420 of piston portion 400 does not rotate.
As mentioned above, along with the rotatingshaft 420 of piston portion 400 moves down, the notch portion 411 of underpart that is formed on piston 440 is corresponding with the exhaust port 522 on the block 510 that is formed on nozzle unit 500.Simultaneously, be positioned at piston 440 pressurizations that the fluid of 520 li of the inner spaces of block 510 is moved downward and flow to nozzle 530 by exhaust port 522, being discharged to again afterwards outside (state of Fig. 6 and Fig. 7 c).
According to the lasting driving of running shaft drive portion 20, cam mechanism 100 execution works, and repeatedly carry out thus fluid inflow step as above and fluid expulsion step, thus fluid can continue to be discharged on object.
when the piston 440 of piston portion 400 upwards and when moving down for piston 440 is not rotated, when should the roller 240 on being installed on the link member 210 of drive portion 200 up and down reciprocatingly entering on the first cam part 110 of cam mechanism 100 dead point and lower dead centre, make first and second discoid panel 121 of the second cam part 120 of cam mechanism 100, 122 with first and second roller 321A, 321B, 321C, 322A, 322B, the outer circumferential face of 322C is arranged accordingly and is formed on first and second discoid panel 121, bump 121A on 122, 121B, 122A, 122B.
Below, with reference to the detailed functions of each description of drawings according to the device for draining fluid of one embodiment of the invention of above-mentioned steps work.
Device for draining fluid according to an embodiment of the invention, as shown in Figure 2, end on the rotatingshaft 420 of the piston portion 400 corresponding with the bottom surface of the flat board 220 of drive portion 200 up and down reciprocatingly is equipped with plane spherical bearing 480.
The planar surface portion of plane spherical bearing 480 contacts with the bottom surfaces of the flat board 220 of drive portion 200 up and down reciprocatingly, and sphere section is supported on the hemispherical depression face 421 that is formed at end face on rotatingshaft 420.
As previously mentioned, the flat board 220 that is connected with the link member 210 of drive portion 200 up and down reciprocatingly makes progress and is rotated down centered by the second hinge axis 222, and in this process, dull and stereotyped 220 keep heeling conditions.On the contrary, carrying out vertical line with the rotatingshaft 420 of dull and stereotyped 220 contacted piston portions 400 moves.
According to plane spherical bearing 480, the rotatingshaft 420 that carries out the piston portion 400 that vertical line moves can remain surface contact state with the flat board 220 that carries out hinge movement, thereby dull and stereotyped 220 rotating force (downward locomotivity) can be delivered to the rotatingshaft 420 of piston portion 400 exactly.
In the present invention, flow into the amount of fluid of 520 li of inner spaces of block 510 of nozzle unit 500 and piston portion 400 piston 440 to move up and down distance proportional.That is, the amount of moving up and down of piston 440 is larger, and the amount of fluid of 520 li of inner spaces of block 510 that flow into nozzle unit 500 is just more.
The central shaft 215 of link member 210,216 and the rotatingshaft 420 of piston portion 400 among distance (D of Fig. 3) between the heart constant all the time, and under the condition that the left side of link member 210 (with dull and stereotyped 220 corresponding parts) rotates up and down with identical angle all the time, the angle of inclination of the flat board 220 of the amount of moving up and down of piston 440 when rotating is proportional.That is, dull and stereotyped 220 angle of inclination means greatly with the momentum of vertical sliding up and down of the rotatingshaft 420 of dull and stereotyped 220 the contacted piston portion 400 in bottom surface large.
Under the condition of rotating up and down with identical angle all the time in the left side of link member 210, the second hinge axis 222 of dull and stereotyped 220 is longer with distance between the central shaft 215,216 of link member 210, and is just larger based on the angle of inclination of the flat board 220 of the rotation of link member 210.
Thereby for the amount of the fluid of 520 li of the inner spaces that increase the block 510 that flow into nozzle unit 500, preferably should make the distance between the central shaft 215,216 of the second hinge axis 222 of dull and stereotyped 220 and link member 210 elongated.Thus, when between the central shaft 215,216 that increases the second hinge axis 222 of dull and stereotyped 220 and link member 210 apart from the time, the amount of fluid of 520 li of inner spaces that flow into the block 510 of nozzle unit 500 can increase.
According to the discharge object of fluid, need to regulate the disposable discharge capacity of fluid, adopted the length adjustment unit that can regulate dull and stereotyped 220 position with respect to the link member 210 of drive portion 200 up and down reciprocatingly in the present invention for this reason.
If consist of the dull and stereotyped drive portion 230 of length adjustment unit to first direction rotating driveshaft 232 by driving, according to the interaction of the screw section on the inner peripheral surface of the outer circumferential face that is formed on live axle 232 and housing 231, dull and stereotyped 220 can move towards link member 210 along steering channel 211-1, the 212-1,11 that are formed on link member 210 and casing 10.Thereby the distance between the second hinge axis 222 of dull and stereotyped 220 and the central shaft 215,216 of link member 210 diminishes and the distance minimizing (that is, the influx of fluid reduces) that moves up of piston 440.
On the contrary, if to the live axle 232 of second direction pivotal plate drive portion 230, dull and stereotyped 220 can move towards dull and stereotyped drive portion 230 along steering channel 211-1, the 212-1,11 that are formed on link member 210 and casing 10.Elongated and the distance increase that moves up of piston 440 with the distance between the central shaft 215,216 of link member 210 of its result, the second hinge axis 222 of dull and stereotyped 220, thus the influx of fluid can increase.
So, the present invention can come by the length adjustment unit amount of the fluid that simple adjustment discharges.
In addition, in piston portion 400, the lower end of rotatingshaft 420 is equipped with Coupler 470, and is installed with piston 440 on this Coupler 470.As mentioned above, fluid is supplied to nozzle 530 by the notch portion 411 that is formed on piston 440, when therefore using for a long time, is necessary to change or wash nozzle 530 and the piston 440 of the path that is formed with fluid.
When changing/washing piston 440, need not to change the whole rotatingshaft 420 that combines/be connected with other parts, get final product and change again/wash piston 440 after only needing Coupler 470 is separated, can simply carry out replacing/washing step accordingly.
