Description

Technical Field

[0001] The present invention relates to the technical field of dilutors, and more specifically, to a novel hydrodynamic proportional dilutor piston motor mechanism. Background Art

[0002] Dilutors are currently applied in many industries, such as livestock breeding, agricultural irrigation, medical treatment, and machinery manufacturing. In all these industries, it is necessary to proportionally dilute and configure a certain concentration of liquid medicine or cutting fluid. In a dilutor, a piston motor is the core power mechanism, and its function is to supply the liquid medicine or cutting fluid to the supply pipeline through reciprocating motion inside the dilutor. The existing piston motors usually have the following defects:

[0003] 1. It needs to rely on electric drive during operation.

[0004] 2. There are components with mutual contact and sliding friction in the structure of the piston motor that generates driving force. Long-term use will cause serious wear, which will affect the reciprocating motion of the piston motor and ultimately affect the performance of the dilutor.

[0005] In view of this, how to provide a piston motor structure that can solve all or part of the above technical problems is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0006] The present invention aims to solve at least one of the above technical problems in the prior art to some extent.

[0007] To this end, an object of the present invention is to provide a novel hydrodynamic proportional dilutor piston motor mechanism. The piston motor is installed inside the dilutor body and includes:

[0008] A piston main body, which includes an upper cylinder body, a lower cylinder body, and a support platform. The support platform is fixedly arranged at the lower edge of the upper cylinder body, the lower cylinder body is fixedly arranged on the lower surface of the support platform, and the support platform is provided with a water inlet hole and a water outlet hole penetrating through the upper and lower surfaces. The inner diameter of the upper cylinder body is larger than that of the lower cylinder body. The water inlet hole is located within the inner diameter of the lower cylinder body, and the water outlet hole is located outside the inner diameter of the lower cylinder body;

[0009] A magnet, the support platform is provided with an installation groove, and the magnet is fixedly arranged in the installation groove;

[0010] An upper guide post, the upper surface of the support platform is vertically provided with an upper guide post;

[0011] A lower guide post, the lower surface of the support platform is vertically provided with a lower guide post;

[0012] A support ring assembly, which includes a lower support ring, a connecting rod, and an upper support ring;

[0013] The lower support ring includes a lower support ring body, a first sliding rod, a first sliding sleeve and a first spring. The first sliding rod is vertically arranged on the lower surface of the lower support ring body. The first spring is sleeved on the first sliding rod, its upper end is fixedly connected to the lower support ring body, and its lower end is fixedly connected to the first sliding sleeve. The first sliding sleeve is slidably connected to the first sliding rod. The lower support ring body is provided with a first guiding hole. The lower guiding column is inserted into the first guiding hole. An iron block is arranged on the lower support ring body, and the iron block corresponds to the magnet in position.

[0014] The lower end of the connecting rod is fixedly connected to the lower support ring body. A water inlet hole sealing assembly is arranged near the bottom of the connecting rod, and the connecting rod corresponds to the water inlet hole in position.

[0015] The upper support ring includes an upper support ring body, a second sliding rod, a second sliding sleeve, a second spring and a water outlet hole sealing assembly. The second sliding rod is vertically arranged on the upper surface of the upper support ring body. The second spring is sleeved on the second sliding rod, its lower end is fixedly connected to the upper support ring body, and its upper end is fixedly connected to the second sliding sleeve. The second sliding sleeve is slidably connected to the second sliding rod. The upper support ring body is provided with a second guiding hole. The upper guiding column is inserted into the second guiding hole. An iron block is arranged on the upper support ring body, and the iron block corresponds to the magnet in position. The water outlet hole sealing assembly is fixedly connected to the upper support ring and corresponds to the water outlet hole in position. The upper end of the connecting rod passes through the water inlet hole and is fixedly connected to the lower surface of the upper support ring body.

[0016] A limiting ring, which includes an upper limiting ring and a lower limiting ring. The upper limiting ring is fixedly arranged on the inner upper surface of the diluter body, and the lower limiting ring is fixedly arranged on the inner lower surface of the diluter body. The upper limiting ring corresponds to the second sliding sleeve in position, and the lower limiting ring corresponds to the first sliding sleeve in position. The lower cylinder body is hermetically communicated with the water supply pipeline of the diluter body.

[0017] When the upper support ring approaches the support platform, the magnet can adsorb the iron block in the upper support ring body. At this time, the water outlet hole sealing assembly seals the water outlet hole. When the lower support ring approaches the support platform, the magnet can adsorb the iron block in the lower support ring body. At this time, the water inlet hole sealing assembly seals the water inlet hole.

[0018] The beneficial effects of the present invention are:

[0019] 1. The piston motor no longer needs to rely on electric drive. This application proposes and adopts a brand-new "water pressure drive structure of the water supply pipeline", which uses water pressure to provide power for the up and down movement of the piston motor, fundamentally reducing the electric cost of the diluter.

[0020] 2. A combined structure of a spring and a magnet is adopted to provide driving support for the movement direction change of the support ring assembly and the adsorption change of the magnet. After the movement direction of the support ring assembly changes, the movement direction of the piston motor can be changed. The operation of this driving structure only requires the elastic forces of the first spring and the second spring and the magnetic force of the magnet, without generating friction, which can avoid wear, enable the diluter to be used for a long time, and improve the performance and service life of the diluter.

[0021] In the above technical solution, when the piston motor moves upward and approaches the upper surface of the diluter, the upper limit ring contacts the second sliding sleeve. Since the piston motor moves upward, the upper limit ring will press down the second sliding sleeve, and at the same time compress the second spring. The elastic force of the second spring gradually increases. When the elastic force of the second spring is greater than the adsorption force between the magnet and the iron block of the lower support ring, the second spring will instantly expand from the compressed state, bounce the support ring assembly downward, the magnet separates from the iron block of the lower support ring, and adsorbs to the iron block of the upper support ring. Vice versa, the first spring on the lower limit ring can bounce the support ring assembly upward, the magnet separates from the iron block of the upper support ring and adsorbs to the iron block of the lower support ring.

[0022] Further, the support platform is recessed downward to form a mounting groove, and the lower surface of the mounting groove is located inside the lower cylinder body; the magnet is installed in the mounting groove, and a cover plate is fixedly arranged on the upper surface of the mounting groove.

[0023] In the above technical solution, the material of the mounting groove and the cover plate can be selected the same as that of the upper cylinder body and the lower cylinder body, such as plastic, etc. The lower surface of the mounting groove and the cover plate will not affect the magnetic force of the magnet. The magnet can pass through the cover plate and adsorb to the iron block on the upper support ring, or pass through the lower surface of the mounting groove and adsorb to the iron block on the lower support ring.

[0024] Further, the water inlet hole sealing assembly includes a first sealing ring and a first sealing groove. The first sealing groove is arranged near the bottom of the connecting rod, and the first sealing ring is installed in the sealing groove. When the magnet adsorbs the iron block inside the lower support ring body, the first sealing ring blocks the water inlet hole.

[0025] Further, the water outlet hole sealing assembly includes a check valve rod, a second sealing groove and a second sealing ring. The check valve rod is fixed on one side of the upper support ring and corresponds to the position of the water outlet hole. A second sealing groove is arranged at the bottom of the check valve rod, and the sealing ring is installed in the second sealing groove. When the magnet adsorbs the iron block inside the upper support ring body, the second sealing ring blocks the water outlet hole.

[0026] In the above technical solution, since the upper support ring and the lower support ring are connected by a connecting rod, when the magnet adsorbs to the iron block on the upper support ring, it will necessarily separate from the iron block on the lower support ring, and vice versa; therefore, when the water inlet hole is sealed, the water outlet hole will open, and when the water outlet hole is sealed, the water inlet hole will open.

[0027] Furthermore, the support platform is circular, the water inlet hole is located at the center of the support platform, there are three installation grooves, which are evenly distributed outside the water inlet hole, and there are three water outlet holes, which are evenly distributed at a position near the outer edge of the support platform.

[0028] Furthermore, three upper guide posts and three lower guide posts are respectively provided. The upper guide posts are arranged at intervals with the water inlet hole, the water outlet hole and the installation grooves, and the lower guide posts are arranged at intervals with the water inlet hole, the water outlet hole and the installation grooves.

The upper limiting ring 9 is fixedly arranged on the inner upper surface of the diluter 11 body, and the lower limiting ring 10 is fixedly arranged on the inner lower surface of the diluter 11 body. The upper limiting ring 9 corresponds to the position of the second slide sleeve 803, and the lower limiting ring 10 corresponds to the position of the first slide sleeve 503. The lower cylinder body 102 is hermetically communicated with the water supply pipeline 1104 of the diluter 11 body; when the upper support ring 8 approaches the support platform 103, the magnet 2 can adsorb the iron block 6 in the upper support ring body 801, and at this time the water outlet hole 105 sealing assembly seals the water outlet hole 105; when the lower support ring 5 approaches the support platform 103, the magnet 2 can adsorb the iron block 6 in the lower support ring body 501, and at this time the water inlet hole 104 sealing assembly seals the water inlet hole 104.

[0048] Such as Figures 1-2As shown in the figure, in this embodiment, the support platform 103 is circular, the water inlet hole 104 is located at the center of the support platform 103, there are three installation grooves 106, which are evenly distributed outside the water inlet hole 104, and there are three water outlet holes 105, which are evenly distributed at a position close to the outer edge of the support platform 103; three upper guide posts 3 and three lower guide posts 4 are provided respectively.

[0049] As Figure 4 shown, the support platform 103 is recessed downward to form the installation groove 106, and the lower surface of the installation groove 106 is located inside the lower cylinder 102; the magnet 2 is installed in the installation groove 106, and a cover plate 12 is fixedly arranged on the upper surface of the installation groove 106.

[0050] As Figure 3 and Figure 5 shown, the water inlet hole 104 sealing assembly includes a first sealing ring 13 and a first sealing groove 701. The first sealing groove 701 is arranged close to the bottom of the connecting rod 7. The first sealing ring 13 is installed in the sealing groove. When the magnet 2 adsorbs the iron block 6 in the lower support ring body 501, the first sealing ring 13 blocks the water inlet hole 104.

[0051] As Figure 3 and Figure 4 shown, the water outlet hole 105 sealing assembly includes a one-way valve rod 14, a second sealing groove 1401 and a second sealing ring 15.

A second sealing groove 1401 is arranged at the bottom of the one-way valve rod 14, and the sealing ring is installed in the second sealing groove 1401. When the magnet 2 adsorbs the iron block 6 in the upper support ring body 801, the second sealing ring 15 blocks the water outlet hole 105.

[0052] As Figures 3-4 shown, in this embodiment, a chute is formed on the first sliding rod 502, and the first sliding sleeve 503 is connected to the chute through a pin to realize sliding on the first sliding rod 502. The second sliding rod 802 and the second sliding sleeve 803 adopt the same sliding connection structure.

[0053] In this embodiment, the limiting ring is of a cylindrical structure, and other shaped limiting members can also be used to limit the first sliding sleeve 503 and the second sliding sleeve 803.

[0054] The specific working process is as follows:

[0055] As Figure 6As shown, after the piston motor 1 is installed inside the diluter 11, the inside of the diluter 11 can be divided into a first cavity 1101, a second cavity 1102, and a third cavity 1103. Among them, the second cavity 1102 is communicated with the water supply pipeline 1104 and the lower cylinder 102, the first cavity 1101 is communicated with the upper cylinder 101, and the third cavity 1103 is communicated with the water outlet pipeline 1105.

[0056] As Figures 7-9 shown, in this state, the magnet 2 adsorbs to the iron block 6 on the lower support ring 5. The lower support ring 5 fits against the lower surface of the support platform 103. The first sealing ring 13 near the bottom of the connecting rod 7 closely adheres to the inner side wall of the water inlet hole 104. At this time, the water inlet hole 104 is blocked and the water outlet hole 105 is in normal use.

[0057] As Figure 6 and Figure 9 shown, when the water inlet hole 104 is blocked and the water outlet hole 105 is in normal use, the second cavity 1102 is separated from the first cavity 1101, the first cavity 1101 is communicated with the third cavity 1103, the internal pressure of the second cavity 1102 is the water pressure of the water supply pipeline 1104, and the internal pressures of the first cavity 1101 and the third cavity 1103 are 0. Therefore, the internal pressure of the second air will push the entire piston motor 1 upward. When the second sliding sleeve 803 on the upper support ring 8 contacts the upper limit ring 9, the second sliding sleeve 803 starts to press down the second spring 804, and the elastic force of the second spring 804 gradually increases. When the elastic force of the second spring 804 is greater than the adsorption force between the magnet 2 and the iron block 6 on the lower support ring 5, the magnet 2 separates from the iron block 6 on the lower support ring 5, and at the same time, the entire support ring assembly is still under the action of the elastic force of the second spring 804 and moves downward until the magnet 2 adsorbs to the iron block 6 on the upper support ring 8 and becomes Figure 4 and Figures 10-11 the state shown.

[0058] In Figure 11 the state shown, the upper support ring body 801 closely adheres to the support platform 103, and the second sealing ring 15 on the one-way valve rod 14 closely adheres to the inner side wall of the water outlet hole 105. At this time, the water outlet hole 105 is blocked and the water inlet hole 104 is in normal use.

[0059] As Figure 6 and Figure 11, when the water outlet hole 105 is blocked and the water inlet hole 104 is in normal use, the second cavity 1102 communicates with the first cavity 1101, the first cavity 1101 is separated from the third cavity 1103, and the internal pressures of the first cavity 1101 and the second cavity 1102 are both the water pressure of the water supply pipeline 1104, and the internal pressure of the third cavity 1103 is still 0. Since the cross-section of the first cavity 1101 is the same as that of the upper cylinder 101 and the cross-section of the second cavity 1102 is the same as that of the lower cylinder 102, the cross-section of the first cavity 1101 is larger than that of the second cavity 1102. Therefore, the piston motor 1 as a whole is subject to a downward resultant force, which pushes the piston motor 1 downward. Similarly, when the first sliding sleeve 503 of the lower support ring 5 contacts the lower limit ring 10, the first spring 504 will spring the support ring assembly upward, and the magnet 2 will adsorb the iron block 6 of the lower support ring 5 again, returning to Figure 9 the state shown.

[0060] By repeating the above working process, the piston motor 1 can realize reciprocating motion by relying on the water pressure of the water supply pipeline 1104, the elastic force of the spring, and the adsorption force of the magnet 2, and continuously supply water to the water outlet pipeline 1105. The whole process does not rely on electric drive and has no friction.

[0061] The present invention provides a new type of piston motor mechanism for a hydrodynamic proportional diluter, which has the following advantages compared with existing products: 1. The piston motor no longer needs to rely on electric drive. The present application proposes and adopts a brand-new "water pressure drive of the water supply pipeline" structure, which uses water pressure to provide power for the up and down movement of the piston motor, fundamentally reducing the power cost of the diluter. 2. A combined structure of a spring and a magnet is adopted to provide driving support for the movement direction change of the support ring assembly and the adsorption change of the magnet. After the movement direction of the support ring assembly changes, the movement direction of the piston motor can be changed. The operation of this driving structure only requires the elastic forces of the first spring and the second spring and the magnetic force of the magnet, without generating friction, which can avoid wear, and can be used by the diluter for a long time, improving the performance and service life of the diluter.
