Description

Technical Field

[0001] This utility model belongs to the field of vegetable technology and relates to fertilizer applicators, specifically a Venturi fertilizer applicator for vegetables. Background Technology

[0002] A venturi fertilizer applicator for vegetables is an automatic fertilization device that utilizes the Venturi principle. It increases water flow velocity while reducing pressure to draw liquid fertilizer into the irrigation water, achieving uniform mixing and efficient fertilization. Its main features include saving time and labor, applicability to various irrigation systems, and environmental friendliness, reducing fertilizer waste and runoff. To use it, simply connect the applicator to the irrigation system, add the appropriate amount of fertilizer, and start irrigation to achieve precise fertilization, thereby improving crop yield and quality.

[0003] However, most existing venturi fertilizer applicators use wire to tie the hose to the applicator during use. However, the wire is not a stable fix and is prone to loosening over time, leading to leakage at the connection point. This affects the continuity and effectiveness of fertilization, so this problem needs to be solved. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies by proposing a Venturi fertilizer applicator for vegetables. The technical problem this invention aims to solve is that while the hose is bound to the fertilizer applicator with wire, the wire's fixing effect is not stable enough and it tends to loosen over time, leading to leakage at the connection point and affecting the continuity and effectiveness of fertilization.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A venturi fertilizer applicator for vegetables includes a main body, with connecting pipes fixedly connected to both ends of the main body. Baffles are fixedly connected to the surfaces of both connecting pipes, and multiple pressure plates are provided on the surfaces of both baffles. These pressure plates cooperate with the connecting pipes and are evenly arranged in a ring. Each pressure plate has a support mechanism on its surface near the baffle for supporting the pressure plate. A collection groove is formed on the surface of both connecting pipes, and the two collection grooves are ring-shaped. An air bladder is installed inside each of the two collection grooves, and an expansion mechanism for inflating the air bladder is provided at the bottom of each of the two collection grooves. The pressure plates prevent the hoses from loosening.

[0007] As a further embodiment of this utility model, the support mechanism includes two support rods, both of which are fixedly connected to the surface of the baffle. The pressure plate is slidably sleeved on the surface of the two support rods. A reinforcing plate is fixedly connected to the surface of the pressure plate near the storage groove. Springs are sleeved on the surface of both support rods. One end of each spring is fixedly connected to one side of the pressure plate, and the other end of each spring is fixedly connected to one side of the baffle. The pressure plate can be supported by the support rods.

[0008] As a further embodiment of this utility model, the expansion mechanism includes a piston chamber, which is opened on one side of the connecting pipe and is interconnected with the storage groove. A piston pad is slidably connected inside the piston chamber. A connecting ring is fixedly connected to the surface of the piston pad away from the airbag. A moving mechanism for moving the piston pad is provided on the surface of the connecting ring away from the piston pad. The airbag can be inflated by the piston pad.

[0009] As a further embodiment of this utility model, the moving mechanism includes multiple limiting grooves, all of which are formed on the surface of the main body and are evenly arranged in a ring. Each of the multiple limiting grooves has a limiting plate slidably connected inside. The same adjusting ring is fixedly connected to the surface of the multiple limiting plates away from the main body. A connecting ring is fixedly connected to one side of the adjusting ring, and the adjusting ring cooperates with multiple pressure plates. An L-shaped ring is fixedly connected to the surface of the adjusting ring away from the connecting ring. A fixing ring is slidably fitted onto the surface of the L-shaped ring, and the fixing ring is connected to the main body by threads. By setting the adjusting ring, the piston pad can be moved.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model employs a clamping and fixing technique using pressure plates to secure the hose, thus preventing the hose from loosening. This effectively solves the problem of inconsistent fixing with wire, which can easily loosen over time, leading to leaks at the connection and affecting the continuity and effectiveness of fertilization. An adjusting ring is installed on one side of the fixing ring, so that the adjusting ring moves synchronously when the fixing ring moves. Multiple pressure plates are installed on the surface of the connecting pipe, arranged evenly in a ring. These pressure plates cooperate with the adjusting ring. Because the front end of the adjusting ring is inclined, it compresses the pressure plates as the adjusting ring moves, causing the pressure plates to move closer together, thereby clamping and fixing the hose.

Baffles 201 are fixedly connected to the surfaces of both connecting pipes 2. Multiple pressure plates 3 are provided on the surfaces of both baffles 201, and these pressure plates 3 are arranged in a ring-shaped arrangement in cooperation with the connecting pipes 2. Support mechanisms for supporting the pressure plates 3 are provided on the surface of each pressure plate 3 near the baffles 201. Storage grooves 202 are provided on the surfaces of both connecting pipes 2, and these grooves are arranged in a ring. Airbags 204 are installed inside each storage groove 202. The airbags 204 prevent leakage at the connection points. An expansion mechanism for inflating the airbags 204 is provided at the bottom of each storage groove 202. The pressure plates 3 prevent the hoses from loosening.

[0021] Preferably, the support mechanism includes two support rods 302, both of which are fixedly connected to the surface of the baffle 201. The pressure plate 3 is slidably sleeved on the surface of the two support rods 302. A reinforcing plate 301 is fixedly connected to the surface of the pressure plate 3 near the storage groove 202. Springs 303 are sleeved on the surface of both support rods 302. The pressure plate 3 can be adjusted by the springs 303. One end of each spring 303 is fixedly connected to one side of the pressure plate 3, and the other end of each spring 303 is fixedly connected to one side of the baffle 201. The pressure plate 3 can be supported by the support rods 302.

[0022] Preferably, the expansion mechanism includes a piston chamber 203, which is located on one side of the connecting pipe 2 and is interconnected with the storage groove 202. A piston pad 402 is slidably connected inside the piston chamber 203. A connecting ring 401 is fixedly connected to the surface of the piston pad 402 away from the airbag 204. The surface of the connecting ring 401 away from the piston pad 402 is provided with a moving mechanism for moving the piston pad 402. The airbag 204 can be inflated by the piston pad 402.

[0023] Furthermore, the moving mechanism includes multiple limiting grooves 404, all of which are formed on the surface of the main body 1 and are evenly arranged in a ring. Each limiting groove 404 has a limiting plate 403 slidably connected inside it. The same adjusting ring 4 is fixedly connected to the surface of the limiting plate 403 away from the main body 1. A connecting ring 401 is fixedly connected to one side of the adjusting ring 4, and the adjusting ring 4 and multiple pressure plates 3 are configured to cooperate with each other. An L-shaped ring 405 is fixedly connected to the surface of the adjusting ring 4 away from the connecting ring 401. A fixing ring 5 is slidably sleeved on the surface of the L-shaped ring 405, and the fixing ring 5 is connected to the main body 1 by threads.

[0024] Working Principle: During use, the flexible hose is inserted into the connecting pipe 2. A baffle 201 is installed on the surface of the connecting pipe 2. During insertion, the flexible hose contacts the baffle 201. After the flexible hose is fully inserted, the fixing ring 5 is rotated. Because the fixing ring 5 is connected to the main body 1 by threads, it moves forward during rotation. An adjusting ring 4 is also installed on one side of the fixing ring 5. Therefore, when the fixing ring 5 moves, the adjusting ring 4 moves synchronously. Multiple pressure plates 3 are installed on the surface of the connecting pipe 2, and these pressure plates 3 are evenly arranged in a ring. All pressure plates 3 cooperate with the adjusting ring 4. Because the front end of the adjusting ring 4 is inclined, it compresses the multiple pressure plates 3 as the adjusting ring 4 continues to move. Furthermore, multiple pressure plates 3 will move closer together during the compression process to clamp and fix the hose. A piston chamber 203 is also installed inside the connecting pipe 2. A piston pad 402 is installed inside the piston chamber 203, and the piston pad 402 is connected to the adjusting ring 4 through the connecting ring 401. When the adjusting ring 4 moves, the piston pad 402 will also move synchronously to compress the gas in the piston chamber 203. An air bladder 204 is installed on the surface of the connecting pipe 2, and the air bladder 204 is connected to the piston chamber 203. Therefore, when the piston pad 402 moves inside the piston chamber 203, it can fill the air bladder 204 with the gas in the piston chamber 203, thereby inflating it. The inflated air bladder 204 can make tight contact with the hose to avoid leakage.
