Description

Technical Field

[0001] This utility model relates to the field of pesticide application leakage prevention technology, and in particular to a leakage prevention device for field application of pesticides to vegetables. Background Technology

[0002] A leak-proof device for pesticide application in vegetable fields is a device used to prevent pesticide or fertilizer from leaking or running off when applying pesticides or fertilizers in farmland.

[0003] Leakage prevention devices for pesticide application in vegetable fields are usually installed on the application device between the pesticide tank and the water pump to prevent pesticide leakage, reduce pesticide pollution to the soil, and prevent leaked pesticides from seeping into the soil and altering the soil's chemical properties and microbial community structure.

[0004] However, existing leak-proof devices for pesticide application still have the following shortcomings in actual use. For example, existing sealing components usually use rubber rings. When the rubber rings are in contact with pesticides for a long time, especially some acidic or alkaline pesticides, the rubber and other sealing materials age, harden, and lose elasticity, which will create gaps between the seal and the connecting parts, causing pesticides to leak from the gaps. This is not conducive to improving the sealing performance of the leak-proof device. Therefore, this utility model proposes a leak-proof device for pesticide application in vegetable fields. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a leak-proof device for the field application of pesticides to vegetables.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a leak-proof device for field application of pesticides for vegetables, comprising a water tank and a water pump, characterized in that a water pump is provided on one side of the water tank, a leak-proof component is provided between the water tank and the water pump, a shock-absorbing component is provided on the leak-proof component, and a buffer component is provided between the water tank and the leak-proof component.

[0007] The leak-proof assembly includes a housing and an inlet pipe. The housing is disposed between the water tank and the water pump. A flexible hose is fixedly connected between the housing and the water pump. The inlet pipe is disposed on the housing at the end away from the flexible hose. A connecting pipe is provided between the inlet pipe and the water tank. The inlet pipe and the connecting pipe are threaded together. A sealing plate is fixedly connected to the end of the connecting pipe near the inlet pipe. A sleeve is fixedly connected to the end of the inlet pipe near the sealing plate. The sealing plate is movably inserted between the inlet pipe and the sleeve.

[0008] In a preferred embodiment, a sealing gasket is provided on the sealing plate and the sleeve, and a sealing groove is provided on the side of the sealing plate and the sleeve near the sealing gasket.

[0009] The technical effect of adopting the above technical solution is that the expansion of the sealing gasket seals the sealing groove, thereby further improving the sealing performance of the leak-proof device.

[0010] In a preferred embodiment, a slider is fixedly connected to the side of the water inlet pipe near the outer casing, and a groove is provided on the side of the outer casing near the slider. The water inlet pipe is rotatably connected to the outer casing through the groove and the slider.

[0011] The technical effect of adopting the above technical solution is that the rotating water inlet pipe is threadedly connected to the connecting pipe.

[0012] In a preferred embodiment, the shock absorption assembly includes a support base and a damping telescopic rod. The support base is disposed at the bottom of the housing, the damping telescopic rod is fixedly connected to the support base, and a spring is sleeved on the damping telescopic rod, the spring being fixedly connected to the support base.

[0013] The technical effect of adopting the above technical solution is to reduce the vibration of the outer casing, which helps to reduce the wear of the leak-proof device caused by vibration.

[0014] In a preferred embodiment, the buffer assembly includes a second sealing groove, a spring sheet, and a second sealing plate. The second sealing groove is located on the side of the water tank near the connecting pipe. The spring sheet is sleeved on the connecting pipe at one end near the second sealing groove. The second sealing plate is located on the side of the second sealing groove near the spring sheet. A third sealing plate is fixedly connected to the side of the second sealing groove near the third sealing plate. An inner groove is located on the side of the second sealing plate near the third sealing plate. The third sealing plate is movably connected to the third sealing plate through the inner groove.

[0015] The technical effect of adopting the above technical solution is to reduce the wear between the water inlet pipe and the connecting pipe, which helps to improve the service life of the leak prevention device and prevent impurities from contaminating the medicine inside the water tank.

[0016] In a preferred embodiment, the inner diameter of the sealing plate three is larger than the inner diameter of the inner groove.

[0017] The technical effect of adopting the above technical solution is that by opening an inner groove, since the outer diameter of the inner groove is larger than the inner diameter of the sealing plate three, the sealing performance of the sealing plate two and the sealing plate three is ensured, while the sealing plate two can also move with the connecting pipe.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] 1. By setting up a leak-proof component, a sealing plate is inserted between the sleeve and the inlet pipe, and the connecting pipe is threaded into the inside of the inlet pipe. This allows the sleeve and the sealing plate to work together to form a multi-layer sealing structure. Due to the aging or wear of the threads between the inlet pipe and the connecting pipe caused by long-term use, gaps may be generated, causing the medicine to leak out from these gaps. At this time, the multi-layer sealing system composed of the sleeve and the sealing plate can effectively seal such leaks, which not only enhances the leak-proof performance of the entire device, but also extends its service life.

[0020] 2. By setting up shock absorption components and buffer components, the damping telescopic rod and spring work together to reduce the impact of vibration transmitted to the shell. If the vibration intensity is large and causes the shell to shift, the connecting pipe will move accordingly and squeeze the spring in the process. After the spring is compressed, it can absorb some energy, thereby reducing the force on the connecting pipe, thus reducing the relative movement between the water inlet pipe and the connecting pipe and reducing the wear between the two.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0032] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a leak-proof device for applying pesticides in the field of vegetables, including a water tank 1 and a water pump 2, characterized in that the water pump 2 is provided on one side of the water tank 1, a leak-proof component 3 is provided between the water tank 1 and the water pump 2, a shock-absorbing component 5 is provided on the leak-proof component 3, and a buffer component 6 is provided between the water tank 1 and the leak-proof component 3.

[0033] like Figure 2 As shown, the leak-proof component 3 includes a housing 31 and an inlet pipe 32. The housing 31 is disposed between the water tank 1 and the water pump 2. A flexible hose 4 is fixedly connected between the housing 31 and the water pump 2. The inlet pipe 32 is disposed on the end of the housing 31 away from the flexible hose 4. A connecting pipe 33 is provided between the inlet pipe 32 and the water tank 1. The inlet pipe 32 and the connecting pipe 33 are threaded together. A sealing plate 34 is fixedly connected to the end of the connecting pipe 33 near the inlet pipe 32. A sleeve 35 is fixedly connected to the end of the inlet pipe 32 near the sealing plate 34. The sealing plate 34 is movably inserted between the inlet pipe 32 and the sleeve 35. By sealing the pipe... The sealing plate 34 is inserted between the sleeve 35 and the inlet pipe 32, and the connecting pipe 33 is threaded into the inside of the inlet pipe 32. The sleeve 35 and the sealing plate 34 cooperate to form a multi-layer sealing layer. After the inlet pipe 32 and the connecting pipe 33 have been used for a long time, the threads on the inlet pipe 32 and the connecting pipe 33 will gradually age and wear, forming gaps between the inlet pipe 32 and the connecting pipe 33, causing the medicine to leak from the gaps. At this time, the sealing layer of the sleeve 35 and the sealing plate 34 will block the leaked medicine, preventing leakage, thereby improving the sealing performance of the leak-proof device and extending the service life of the leak-proof device.

[0034] Furthermore, such as Figure 2 As shown, a sealing gasket 36 is provided on the sealing plate 34 and the sleeve 35. A sealing groove 37 is provided on the side of the sealing plate 34 and the sleeve 35 near the sealing gasket 36. By installing the sealing gasket 36 between the sealing plate 34 and the sleeve 35 and inflating the interior of the sealing gasket 36, the sealing gasket 36 expands and seals the sealing groove 37, thereby further improving the sealing performance of the leak-proof device.

[0035] Furthermore, such as Figure 2As shown, a slider 39 is fixedly connected to the side of the water inlet pipe 32 near the outer shell 31. A groove 38 is provided on the side of the outer shell 31 near the slider 39. The water inlet pipe 32 is rotatably connected to the outer shell 31 through the groove 38 and the slider 39. The groove 38 and the slider 39 cooperate to allow the water inlet pipe 32 to rotate on the outer shell 31, which facilitates the rotation of the water inlet pipe 32 and the threaded connection with the connecting pipe 33.

[0036] To reduce the impact of vibration on the leak-proof component 3, such as Figure 2 As shown, the shock absorption assembly 5 includes a support base 51 and a damping telescopic rod 52. The support base 51 is located at the bottom of the housing 31, and the damping telescopic rod 52 is fixedly connected to the support base 51. A spring 53 is sleeved on the damping telescopic rod 52, and the spring 53 is fixedly connected to the support base 51. Through the cooperation of the damping telescopic rod 52 and the spring 53, the support base 51 is supported together, while the vibration of the housing 31 is reduced, which helps to reduce the wear of the anti-leakage device caused by vibration.

[0037] To ensure a better fit between the connecting pipe 33 and the inlet pipe 32, and to prevent wear caused by relative displacement between the inlet pipe 32 and the connecting pipe 33 due to vibration, such as... Figure 3 - Figure 4 As shown, the buffer assembly 6 includes a second sealing groove 61, a spring piece 62, and a second sealing plate 63. The second sealing groove 61 is located on the side of the water tank 1 near the connecting pipe 33. The spring piece 62 is sleeved on the connecting pipe 33 at one end near the second sealing groove 61. The second sealing plate 63 is located on the side of the second sealing groove 61 near the spring piece 62. A third sealing plate 64 is fixedly connected to the side of the second sealing groove 61 near the second sealing plate 63. An inner groove 65 is provided on the side of the second sealing plate 63 near the third sealing plate 64. The third sealing plate 64 is movably connected to the second sealing plate 64 through the inner groove 65. When the outer casing 31 vibrates, the outer casing 31 drives the connecting pipe 33 to move. At this time, the connecting pipe 33 squeezes the spring 62, so that the spring 62 buffers the force on the connecting pipe 33, thereby reducing the relative displacement between the water inlet pipe 32 and the connecting pipe 33, reducing the wear between the water inlet pipe 32 and the connecting pipe 33, which is conducive to improving the service life of the leak-proof device. Furthermore, by sliding the sealing plate 2 63 inside the sealing groove 2 61, the sealing plate 2 63 and the sealing plate 3 64 cooperate to prevent impurities from entering the interior of the water tank 1 through the sealing groove 2 61, thus preventing impurities from contaminating the medicine inside the water tank 1.

[0038] Furthermore, such as Figure 4As shown, the inner diameter of the sealing plate 64 is larger than the inner diameter of the inner groove 65. By opening the inner groove 65, since the outer diameter of the inner groove 65 is larger than the inner diameter of the sealing plate 64, the sealing plate 63 is always slidably connected to the sealing plate 64. This ensures the sealing performance of the sealing plate 63 and the sealing plate 64, while also allowing the sealing plate 63 to move with the connecting pipe 33, thus preventing the connecting pipe 33 from getting stuck.

[0039] Working principle: such as Figure 1 - Figure 4 As shown:

[0040] In use: First, insert the sealing plate 34 between the sleeve 35 and the water inlet pipe 32. Rotate the water inlet pipe 32 so that it rotates along the groove 38 via the slider 39 and is threadedly connected to the connecting pipe 33, so that the sleeve 35 and the sealing plate 34 cooperate to form a multi-layer sealing layer. Then, inflate the sealing gasket 36 to expand it and seal the sealing groove 37, thereby improving the sealing performance of the leak-proof device. Next, install the support base 51 between the outer shell 31 and the external application device. When the external application device vibrates, the damping telescopic rod 52 and the spring 53 cooperate. To reduce the vibration experienced by the outer casing 31, when the vibration is too great and causes displacement of the outer casing 31, the connecting pipe 33 moves with the outer casing 31. The connecting pipe 33 squeezes the spring 62, which buffers the force on the connecting pipe 33, thereby reducing the relative displacement between the water inlet pipe 32 and the connecting pipe 33 and reducing the wear between them. By sliding the sealing plate 2 63 inside the sealing groove 2 61, the sealing plate 2 63 and the sealing plate 3 64 cooperate to prevent impurities from entering the interior of the water tank 1 through the sealing groove 2 61, thus preventing impurities from contaminating the medicine inside the water tank 1.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
