Embodiment
Below, the nutrient solution pusher of the present invention is described in detail with reference to accompanying drawing.
It is as shown in Figure 1-2 the first embodiment of nutrient solution pusher of the invention, it includes：Cylinder 10, push rod 20,
Piston head, sliding block 24.
Piston head includes sealing shroud 22, Inner cores 21；Inner cores 21 are formed by rigid plastics；Inner cores 21 are in its periphery by sealing shroud
22 covering, the second end of Inner cores 21, which reach out to, is provided with least one pair of support arm 23, at least one pair of support arm 23 it is every
Support arm 23 is located directly opposite to each other at the periphery close to Inner cores 21；Each support arm 23 has been respectively formed on pilot hole 23a；
A sliding block 24 is slideably inserted with each pilot hole 23a.Between each inner side of support arm 23 and the second end of Inner cores 21 also
Reinforcement 26 can be further set.
The first end of sliding block 24 is provided with friction cushion 25, and the second end of sliding block 24 is provided with the first hole 24a.
The first end of push rod 20 is formed with least one pair of branch piece 27, and each pair branch piece 27 at least one pair of branch piece 27 is distinguished
Form the two opposite sides in the first end of push rod 20；A second hole 27a is formed with each branch piece 27；One the first hole 24a
One the second hole 27a of correspondence；The first end of push rod 20 is formed with pushing hands 30.
A rigid connecting rod is connected between a first hole 24a and second hole of a corresponding 27a
28, the first end of rigid connecting rod 28 is rotatably inserted in the first hole 24a, and the second end of rigid connecting rod 28 is rotationally
It is inserted in the second hole 27a.
Spring 29 is further supported by between the second end of Inner cores 21 and the first end of push rod 20；Spring 29 not by
To push rod 20 thrust when, rigid connecting rod favours push rod 20.
Piston head is contained in cylinder 10, and sealing shroud 22 is contacted with the inner surface of cylinder 10, and nutrient solution formation is sealed.
When pushing nutrient solution, thrust is on push rod 20, and the first end of push rod 20 is entered by spring 29 to Inner cores 21
Row is promoted；Spring 29 can be shortened by thrust, and thus the first end of push rod 20 is close to the end of Inner cores 21 second, rigid connecting rod
Angle between 28 and push rod 20 becomes big, as shown in Fig. 2 thus promoting sliding block 24 to slide so that friction cushion 25 closely with
The inwall of cylinder 10 is contacted, resistance to sliding increase, thus hinders piston head quickly to move.
It is as Figure 7-8 the second embodiment of nutrient solution pusher of the invention, it includes：Cylinder 10, push rod 20,
Piston head.
Piston head includes sealing shroud 22, Inner cores 21；Inner cores 21 are formed by rigid plastics；Inner cores 21 are in its periphery by sealing shroud
22 coverings, the second end of Inner cores 21, which reach out to, is provided with least one pair of support arm 23, each pair of at least one pair of support arm 23
Support arm 23 is located directly opposite to each other at the periphery close to Inner cores 21；Each support arm 23 is constituted by spring leaf.
Friction cushion 25 is formed on each support arm 23, the second end of friction cushion 25 is formed with the first hole 24a.
The first end of push rod 20 is formed with least one pair of branch piece 27, the difference shape of each pair branch piece 27 at least one pair of branch piece 27
Into the two opposite sides of the first end in push rod 20；A second hole 27a is formed with each branch piece 27；One 24a pairs of the first hole
Answer a second hole 27a.The first end of push rod 20 is formed with pushing hands 30.
A rigid connecting rod is connected between a first hole 24a and second hole of a corresponding 27a
28, the first end of rigid connecting rod 28 is rotatably inserted in the first hole 24a, and the second end of rigid connecting rod 28 is rotationally
It is inserted in the second hole 27a.
Spring 29 is further supported by between the second end of Inner cores 21 and the first end of push rod 20；Spring 29 not by
To push rod 20 thrust when, rigid connecting rod 28 favours push rod 20.
Piston head is contained in cylinder 10, and sealing shroud 22 is contacted with the inner surface of cylinder 10, and nutrient solution formation is sealed.
When pushing nutrient solution, thrust is on push rod 20, and the first end of push rod 20 is entered by spring 29 to Inner cores 21
Row is promoted；Spring 29 can be shortened by thrust, and thus the first end of push rod 20 is close to the end of Inner cores 21 second, rigid connecting rod
Angle between 28 and push rod 20 becomes big, and thus support arm 23 is bent outwardly so that friction cushion 25 closely with cylinder inboard wall
Contact, resistance to sliding increase, thus hinders piston head quickly to move.
Spring 29 is not when by the thrust of push rod 20, and the angle of rigid connecting rod 28 and push rod is 30-60 degree.
When spring is fully compressed, the angle of rigid connecting rod and push rod 20 is 90 degree, i.e., now rigid connecting rod hangs down
Directly in push rod 20.
Support arm 23 is preferably two pairs of support arms 23；Accordingly, branch piece 27 is also two pairs of branch pieces 27.
Two pairs of branch pieces 27 are in crossing distribution, accordingly, two pairs of omnidirectional distributions of support arm 23.
So, push rod is supported in X, Y both direction so that push rod is consolidated, and the friction cushion that is multiplied
Frictional force.
Before push rod is pushed, friction cushion and cylinder inboard wall keep preset distance, or be only lightly with cylinder inwall
Contact, now promotes the resistance being subject to be mainly the frictional force of piston head and cylinder inwall.
When pushing, spring is compressed so that friction cushion is moved to the direction of cylinder inwall, or is further pressed in cylinder
On inwall, but the frictional force still very little that now friction cushion is produced, now promote the resistance being subject to be still mainly piston head with
The frictional force of cylinder inwall.
When the thrust of push reaches predetermined value, friction cushion be tightly resisted against on an inwall, now promote by
Resistance include the frictional force of piston head and cylinder inwall, the frictional force of friction cushion and cylinder inwall, and friction cushion and cylinder inwall
Frictional force be main frictional force.
By above-mentioned structure, when thrust reaches predetermined value, propelling resistance can be greatly increased, and thus limit nutrient solution quilt
Quickly propel.
In order that the modification for obtaining the cylinder that friction pad is caused to the pressure of cylinder inwall is not interfered between sealing shroud and cylinder inwall
Sealing, friction cushion is remote enough with the distance of sealing shroud.
