Description

Technical Field

[0001] This utility model relates to the field of dosing pump technology, and more specifically, to a multifunctional dosing pump for integrated water, fertilizer and pesticide spraying. Background Technology

[0002] In recent years, the maintenance of green landscapes in urban communities has faced new challenges. On the one hand, traditional manual spraying of pesticides and fertilizers is inefficient and difficult to cover evenly, consuming a lot of manpower. On the other hand, extensive operation can easily lead to waste of pesticides and fertilizers, and even pollute the soil and water sources in the community, affecting the living environment of residents. At the same time, residents have increasingly higher requirements for the quality of community greening, expecting green plants to be evergreen and flowers to bloom all year round. The application of pesticide dosing pumps in communities is timely. They can accurately control the amount of water, fertilizer and pesticides added, and work with sprinkler systems to achieve automated operation, efficiently maintain green plants and enhance the appearance of the community landscape.

[0003] Existing water, fertilizer and pesticide integrated sprinkler irrigation pumps suffer from wear and tear due to the frequent up-and-down movement of the airtight ring driven by the power valve during long-term high-load use, resulting in insufficient airtightness and significantly reducing the service life of the equipment. Therefore, improvements and optimizations are needed. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a multifunctional water, fertilizer and pesticide integrated sprinkler irrigation dosing pump, which has the advantage of increasing airtightness. A multifunctional water, fertilizer, and pesticide integrated sprinkler irrigation dosing pump includes a pump casing. A first annular shell is fixedly installed inside the pump casing. An inlet pipe is fixedly connected to the left side of the pump casing, and an outlet pipe is fixedly connected to the right side of the pump casing. A second power piston is movably installed above the first annular shell inside the pump casing. A first power piston is fixedly installed on top of the second power piston. A dosing connection pipe is fixedly connected to the bottom of the pump casing. A dosing piston is fixedly installed at the bottom of the second power piston and extends into the dosing connection pipe. A solenoid valve is fixedly installed on top of the first power piston. A flexible annular sleeve is fixedly installed on the outer surface of the first power piston. An annular groove is formed on the outer surface of the flexible annular sleeve, and the annular groove surrounds the flexible annular sleeve. A first airtight ring is movably installed on the inner side of the annular groove and contacts the inner wall of the pump casing. A circular groove is formed on the bottom side of the flexible annular sleeve, and the circular grooves are arranged in a circumferential array. A dosing groove is formed on the bottom side of the dosing connection pipe.

[0005] As a preferred embodiment of the present invention, a buffer plate is fixedly installed between the second power piston and the first power piston, and the buffer plate is inclined between the first power piston and the second power piston and is circumferential. Buffer flexible protrusions are fixedly installed on the outer surface of the buffer plate, and the buffer flexible protrusions are arranged in a circumferential array.

[0006] As a preferred embodiment of the present invention, a second annular shell is fixedly installed on the inner side of the pump housing, and the dosing piston passes through the second annular shell. The second annular shell is in the shape of extending inward, and the bottom width of the dosing piston is greater than the length of the second annular shell extending inward.

[0007] As a preferred embodiment of this utility model, a second airtight ring is movably installed in the rotating groove opened on the outer surface of the dosing piston, and the second airtight ring is in contact with the inner wall of the dosing connection pipe.

[0008] As a preferred technical solution of this utility model, a dosing groove is provided on the bottom side of the dosing connection pipe, and a movable valve is movably installed inside the dosing groove, with the bottom side of the movable valve being arc-shaped.

[0009] As a preferred embodiment of this utility model, a first annular shell is fixedly installed on the inner side of the pump casing, and the first annular shell is located on the inner side of the inlet pipe and the outlet pipe and on the outer side of the second annular shell.

[0010] As a preferred embodiment of this utility model, an inlet pipe and an outlet pipe are fixedly connected to the left and right sides of the pump casing, and a sealing cap is threaded onto the outer surface of the inlet pipe and the outlet pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. In this invention, when the first power piston moves upward, it drives the dosing piston upward. When the dosing piston reaches its moving position, the external medicine is input into the dosing groove. At the same time, high-pressure water flows into the inner side of the flexible annular sleeve through the circular groove. The water then squeezes the annular groove, and the annular groove transmits the squeezing force to the first airtight ring. This increases the squeezing force between the first airtight ring and the inner wall of the pump casing. When the first power piston rises to the moving position, it activates the solenoid valve. The solenoid valve then opens, allowing water to enter the top of the solenoid valve. When the water pressure at the top of the solenoid valve is greater than the pressure below, the first power piston drives the second power piston downward. The water mixed with the medicine is then transported to the external connecting pipe through the outlet pipe. Compared to traditional devices, this device uses water pressure to make the sealing ring more airtight. This design can effectively increase the airtightness of the rising movement, avoid insufficient airtightness caused by frequent up and down movement, and effectively increase the uniformity of mixing, thus extending the service life of the equipment.

[0013] 2. When water flows rapidly into the pump casing through the inlet pipe, it will first impact the first annular shell. Then, when the water is blocked, it will rapidly impact upwards. The water will first hit the buffer flexible protrusions arranged in a circular array. Then, the buffer flexible protrusions and the buffer plate form a uniform guide groove to buffer the water and slowly drive the first power piston to move upwards. Compared with the traditional device, this device can effectively buffer the water from directly impacting the power piston and the airtight ring, thereby reducing the wear rate. At the same time, it can make the power piston move up and down evenly, keeping the ratio of medicine to water constant. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 6As shown, this utility model provides a multifunctional water, fertilizer, and pesticide integrated sprinkler irrigation dosing pump, including a pump housing 1. A first annular shell 2 is fixedly installed inside the pump housing 1. An inlet pipe 4 is fixedly connected to the left side of the pump housing 1, and an outlet pipe 5 is fixedly connected to the right side of the pump housing 1. A second power piston 13 is movably installed above the first annular shell 2 inside the pump housing 1. A first power piston 7 is fixedly installed on the top of the second power piston 13. A dosing connection pipe 18 is fixedly connected to the bottom of the pump housing 1, and a dosing piston 14 is fixedly installed at the bottom of the second power piston 13. 14 extends into the dosing connection pipe 18. A solenoid valve 8 is fixedly installed on the top of the first power piston 7. A flexible annular sleeve 9 is fixedly installed on the outer surface of the first power piston 7. An annular groove 11 is opened on the outer surface of the flexible annular sleeve 9 and the annular groove 11 surrounds the flexible annular sleeve 9. A first airtight ring 12 is movably installed on the inner side of the annular groove 11 and the first airtight ring 12 contacts the inner wall of the pump housing 1. A circular groove 10 is opened on the bottom side of the flexible annular sleeve 9 and the circular groove 10 is arranged in a circumferential array. A dosing groove 20 is opened on the bottom side of the dosing connection pipe 18.

[0023] When the operator connects high-pressure water to the pump casing 1 through the external water pipe sealing cover 6, the high-pressure water passes through the obstruction of the first annular shell 2 and slowly rises. The high-pressure water will then quickly cause the first power piston 7 to move upward. When the first power piston 7 moves upward, it will drive the dosing piston 14 upward. When the dosing piston 14 moves to the moving position, the external medicine will be input into the inside through the dosing tank 20. At the same time, the high-pressure water will flow into the inside of the flexible annular sleeve 9 through the circular groove 10. The water will then squeeze the annular groove 11, and the annular groove 11 will transmit the squeezing force of the annular groove 11 to the first airtight ring 12. This increases the squeezing force between the first airtight ring 12 and the inner wall of the pump casing 1. When the first power piston 7 rises to the moving position, it will activate the solenoid valve 8. Then, the solenoid valve 8 will open the valve to allow water to enter the top of the solenoid valve 8. When the water pressure at the top of the solenoid valve 8 is greater than the pressure below, the first power piston 7 will drive the second power piston 13 downward. Then, the water mixed with the medicine will be transported to the external connecting pipe through the water outlet pipe 5.

[0024] When the first power piston 7 moves upward, it will drive the dosing piston 14 upward. When the dosing piston 14 reaches the moving position, the external agent will be input into the inward through the dosing tank 20. At the same time, high-pressure water will flow into the inner side of the flexible annular sleeve 9 through the circular groove 10. Then, the water will squeeze the annular groove 11, and the annular groove 11 will transmit the squeezing force of the annular groove 11 to the first airtight ring 12. This increases the squeezing force between the first airtight ring 12 and the inner wall of the pump housing 1. Then, when the first power piston 7 rises to the moving position, it will cause... When solenoid valve 8 is activated, it opens to allow water to enter the top of solenoid valve 8. When the water pressure at the top of solenoid valve 8 is greater than the pressure below, the first power piston 7 will drive the second power piston 13 downward. Then, the water mixed with the reagent is transported to the external connection pipe through the outlet pipe 5. Compared with traditional devices, this device uses water pressure to make the sealing ring tighter. This design can effectively increase the airtightness of the rise, avoid insufficient airtightness caused by frequent up and down movement, and effectively increase the uniformity of mixing, thus extending the service life of the equipment.

[0025] A buffer plate 16 is fixedly installed between the second power piston 13 and the first power piston 7. The buffer plate 16 is inclined between the first power piston 7 and the second power piston 13 and is circumferential. Buffer flexible protrusions 17 are fixedly installed on the outer surface of the buffer plate 16 and are arranged in a circumferential array.

[0026] When high-pressure water flows rapidly into the pump casing 1 through the inlet pipe 4, it will first impact the first annular shell 2. Then, when the water is blocked, it will rush upwards. The water will first hit the buffer flexible protrusions 17 arranged in a circular array. Then, the buffer flexible protrusions 17 and the buffer plate 16 form a uniform guide groove to buffer the water and slowly drive the first power piston 7 to move upwards.

[0027] When water flows rapidly into the pump casing 1 through the inlet pipe 4, it will first impact the first annular shell 2. Then, when the water is blocked, it will rush upwards. The water will first hit the buffer flexible protrusions 17 arranged in a circular array. Then, the buffer flexible protrusions 17 and the buffer plate 16 form a uniform guide groove to buffer the water and slowly drive the first power piston 7 to move upwards. Compared with the traditional device, this device can effectively buffer the water from directly impacting the power piston and the airtight ring, thereby reducing the wear rate. At the same time, it can make the power piston move up and down evenly, keeping the ratio of medicine to water constant.

[0028] The pump housing 1 has a second annular shell 3 fixedly installed on its inner side, and the dosing piston 14 passes through the second annular shell 3. The second annular shell 3 is in the shape of extending inward, and the bottom width of the dosing piston 14 is greater than the length of the second annular shell 3 extending inward.

[0029] By ensuring that the bottom width of the dosing piston 14 is greater than the length of the second annular shell 3 extending inward, the dosing piston 14 can be effectively limited when it moves upward.

[0030] The second airtight ring 15 is movably installed in the rotating groove opened on the outer surface of the dosing piston 14, and the second airtight ring 15 is in contact with the inner wall of the dosing connection pipe 18.

[0031] By having the second airtight ring 15 contact the inner wall of the dosing connection pipe 18, the dosing piston 14 can be effectively moved upwards, causing the second airtight ring 15 to rotate in the rotating groove opened in the dosing piston 14, thereby increasing the synchronous sealing performance.

[0032] The dosing connection pipe 18 has a dosing groove 20 on its bottom side, and a movable valve 19 is movably installed inside the dosing groove 20, with the bottom side of the movable valve 19 being arc-shaped.

[0033] The bottom of the movable valve 19 is arc-shaped, which can effectively and evenly deliver the medicine output from the connected medicine output pipe into the pump housing 1. When not delivering medicine, the movable valve 19 can avoid contamination.

[0034] The pump casing 1 has a first annular shell 2 fixedly installed on its inner side, and the first annular shell 2 is located on the inner side of the inlet pipe 4 and the outlet pipe 5 and the outer side of the second annular shell 3.

[0035] By using the first annular shell 2 located inside the inlet pipe 4 and the outlet pipe 5, and the second annular shell 3 located outside, water can be effectively prevented from being directly delivered to the external connection pipe through the outlet pipe 5, thus avoiding water and medicine flowing out before they are fully mixed.

[0036] The pump casing 1 is fixedly connected to the left and right sides with an inlet pipe 4 and an outlet pipe 5, and the outer surfaces of the inlet pipe 4 and the outlet pipe 5 are threaded with sealing caps 6.

[0037] The inlet pipe 4 and outlet pipe 5 are threadedly connected to a sealing cap 6, which can effectively close and protect the inlet pipe 4 and outlet pipe 5 when the whole device is not in use by rotating the sealing cap 6.

[0038] Working principle and usage process of this utility model:

[0039] When the operator connects high-pressure water to the pump casing 1 through the external water pipe sealing cover 6, the high-pressure water passes through the obstruction of the first annular shell 2 and slowly rises. The high-pressure water will then quickly cause the first power piston 7 to move upward. When the first power piston 7 moves upward, it will drive the dosing piston 14 upward. When the dosing piston 14 moves to the moving position, the external medicine will be input into the inside through the dosing tank 20. At the same time, the high-pressure water will flow into the inside of the flexible annular sleeve 9 through the circular groove 10. The water will then squeeze the annular groove 11, and the annular groove 11 will transmit the squeezing force of the annular groove 11 to the first airtight ring 12. This increases the squeezing force between the first airtight ring 12 and the inner wall of the pump casing 1. When the first power piston 7 rises to the moving position, it will activate the solenoid valve 8. Then, the solenoid valve 8 will open the valve to allow water to enter the top of the solenoid valve 8. When the water pressure at the top of the solenoid valve 8 is greater than the pressure below, the first power piston 7 will drive the second power piston 13 downward. Then, the water mixed with the medicine will be transported to the external connecting pipe through the water outlet pipe 5.

[0040] When high-pressure water flows rapidly into the pump casing 1 through the inlet pipe 4, it will first impact the first annular shell 2. Then, when the water is blocked, it will rush upwards. The water will first hit the buffer flexible protrusions 17 arranged in a circular array. Then, the buffer flexible protrusions 17 and the buffer plate 16 form a uniform guide groove to buffer the water and slowly drive the first power piston 7 to move upwards.
