Abstract
Description
Technical Field
[0001] This utility model relates to the field of Venturi water-soluble fertilizer applicators, specifically a microbial water-soluble fertilizer feeder. Background Technology
[0002] The Venturi water-soluble fertilizer applicator is a simple fertilization device designed based on the Venturi effect. It uses the negative pressure generated by the water flow in the variable diameter pipe (throat) to draw the fertilizer solution from the open container into the irrigation system, thus achieving water-fertilizer mixing. Its advantages include simple structure, low cost, stable fertilizer concentration, and suitability for small-scale irrigation.
[0003] Existing Venturi fertilizer applicators utilize the Venturi principle to draw the mixed water-soluble fertilizer solution from the mixing tank into the main pipe for further mixing, thus enabling the application of water-soluble fertilizer. However, a problem exists in practical use: the connecting pipe between the Venturi tube and the mixing tank is only used to deliver the water-soluble fertilizer solution into the Venturi tube. When the applicator is not in use, fertilizer residue easily accumulates on the inner wall of the pipe and the surface of the filter screen at the end, causing corrosion and reducing the pipe's lifespan. Furthermore, it hinders the subsequent application of different water-soluble fertilizers, potentially leading to improper fertilizer mixing and reducing the ease of use of the Venturi water-soluble fertilizer applicator. Therefore, the inventors urgently need to design a cleaning mechanism to remove residual fertilizer solution from the pipe and filter screen, thereby improving the ease of use of the Venturi water-soluble fertilizer applicator. Utility Model Content
[0004] Based on this, the purpose of this utility model is to provide a microbial water-soluble fertilizer feeder to solve the technical problems of residual fertilizer residue in the connecting pipes of Venturi fertilizer applicators, which leads to pipe erosion, mixed pollution, and inconvenient cleaning.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a microbial water-soluble fertilizer feeder, comprising a feeder body and a mixing tank. The feeder body includes a main infusion pipe and a venturi tube. A fourth valve is installed between one side of the venturi tube and the main infusion pipe. The other end of the venturi tube is connected to the main infusion pipe through a corner pipe. A third valve is connected to the venturi tube. The third valve is connected to the mixing tank through a second infusion pipe. The third valve controls whether the feeding operation is performed.
[0006] The fourth valve is closed and the third valve is opened to disrupt the effect of the venturi tube, allowing the liquid inside the main infusion tube to flush the inner wall of the second infusion tube.
[0007] By adopting the above technical solution, the linkage control of the fourth valve and the third valve realizes the dynamic adjustment of the Venturi effect. When the fourth valve is closed and the third valve is opened, the negative pressure effect of the Venturi tube is destroyed. At this time, the high-pressure liquid in the infusion main pipe can directly flush the inner wall of the second infusion tube and the filter structure, effectively removing the fertilizer residue in the pipeline and avoiding pipeline corrosion or cross-contamination of different fertilizers caused by long-term residue.
[0008] Furthermore, a first valve is installed at the front end of the infusion main pipe to block the connection between the infusion main pipe and the external pipeline.
[0009] By adopting the above technical solution, installing a first valve at the front end of the infusion main pipe can quickly block the connection between the feeder body and the external irrigation system, avoid external water flow from interfering with internal operation during cleaning or maintenance, and ensure the independence and safety of system operation. At the same time, the isolation function of the first valve provides the basic conditions for subsequent local pipeline flushing or premixing operation of the mixing tank.
[0010] Furthermore, a second valve is connected to the main infusion pipe, and the second valve is connected to the mixing tank through the first infusion pipe.
[0011] By adopting the above technical solution, bidirectional liquid flow between the infusion main pipe and the mixing tank is realized. During the feeding operation, opening the second valve can directly introduce the liquid in the main pipe into the mixing tank for pre-dilution of fertilizer or secondary dissolution of residual fertilizer in the mixing tank, thereby improving fertilizer utilization.
[0012] Furthermore, the second valve and the first valve are opened to guide the liquid in the infusion tube into the mixing tank.
[0013] By adopting the above technical solution, the liquid in the infusion pipe can be directed to the inside of the mixing tank, realizing the active replenishment or premixing operation of the mixing tank. For example, before starting the feeding, clean water or low-concentration mother liquor can be injected into the mixing tank in advance, and the fertilizer can be dissolved by the water flow impact, reducing the need for manual stirring.
[0014] Furthermore, the second infusion tube is connected to a telescopic tube at one end near the mixing tank. The telescopic tube is a rigid steel pipe, and a filter screen is connected to the other end of the telescopic tube.
[0015] By adopting the above technical solution, it can not only withstand the chemical corrosion of fertilizer solution, but also adapt to changes in liquid level in the mixing tank through the telescopic structure. For example, when extracting high-concentration fertilizer, the length of the telescopic tube can be adjusted to allow the filter screen to penetrate deep into the bottom of the mixing tank, avoiding the intake of sediment impurities; while in low-concentration or cleaning situations, the filter screen can be raised to reduce the risk of clogging.
[0016] Furthermore, an adjustment mechanism is provided above the mixing tank for adjusting the height of the filter screen frame inside the mixing tank. The adjustment mechanism includes a support frame, which is fixed above the mixing tank in a cross-shaped structure. The telescopic tube passes through the support frame and is placed vertically at the central axis of the mixing tank. An adjustment block is threaded to the outside of the telescopic tube.
[0017] By adopting the above technical solution, precise control of the height position of the filter frame inside the mixing tank is achieved. For example, the vertical height can be adjusted according to the changes in the liquid level inside the mixing tank, thereby adapting to the fertilization needs of different crops.
[0018] In summary, the present invention has the following main advantages:
[0019] 1. This utility model closes the fourth valve and opens the third valve, thereby blocking the bypass connection between the Venturi tube and the main infusion tube, disrupting the negative pressure environment generated by the Venturi effect, allowing the high-pressure water flow in the main infusion tube to be directly diverted into the Venturi tube and flow in the opposite direction along the second infusion tube. At this time, the water flow continuously flushes the inner wall of the second infusion tube and the filter screen, forcibly removing fertilizer residues attached to the surface of the pipe and the filter screen, avoiding long-term accumulation of residues that could cause pipe wall corrosion or filter screen blockage, thus significantly improving the durability of the second infusion tube and the filter screen.
[0020] 2. This utility model uses the adjustment block of the adjustment mechanism to drive the telescopic tube to move longitudinally, which can flexibly adjust the immersion depth of the filter screen frame in the mixing tank. When the liquid level or fertilizer concentration in the mixing tank changes, the operator can adjust the filter screen frame to a specific height according to the needs of the crop. For example, when the liquid level is low, the position of the screen frame can be lowered to avoid air intake, or when the fertilizer is layered, the upper clear liquid or the lower high-concentration solution can be extracted, thereby adapting to the different needs of different crops for fertilizer concentration and ensuring the accuracy of fertilization.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Example 1:
[0026] A microbial water-soluble fertilizer feeder, such as Figures 1-3 As shown, the device includes a feeder body 1 and a mixing tank 2. The feeder body 1 includes a main infusion pipe 101 and a venturi tube 102. A fourth valve 108 is installed between one side of the venturi tube 102 and the main infusion pipe 101. The other end of the venturi tube 102 is connected to the main infusion pipe 101 through a bend pipe. A third valve 105 is connected to the venturi tube 102. The third valve 105 is connected to the mixing tank 2 through a second infusion pipe 107. The third valve 105 controls whether the feeding operation is performed.
[0027] Closing the fourth valve 108 and opening the third valve 105 disrupts the effect of the Venturi tube 102, allowing the liquid inside the main infusion pipe 101 to flush the inner wall of the second infusion pipe 107. The linkage control of the fourth valve 108 and the third valve 105 enables dynamic adjustment of the Venturi tube 102 effect. When the fourth valve 108 is closed and the third valve 105 is opened, the negative pressure effect of the Venturi tube 102 is disrupted. At this time, the high-pressure liquid in the main infusion pipe 101 can directly flush the inner wall of the second infusion pipe 107 and the filter structure, effectively removing residual fertilizer residue from the pipeline and avoiding pipeline corrosion or cross-contamination of different fertilizers caused by long-term residue. At the same time, the feeding and cleaning functions are integrated into the same pipeline system, eliminating the need for additional disassembly or the introduction of external cleaning equipment, significantly improving the ease of operation and maintenance efficiency of the feeder. It is especially suitable for scenarios where microbial water-soluble fertilizers are prone to residue and require frequent cleaning.
[0028] See Figure 1 , Figure 2 , Figure 3 A first valve 103 is installed at the front end of the infusion main pipe 101 to block the connection between the infusion main pipe 101 and the external pipeline. Installing the first valve 103 at the front end of the infusion main pipe 101 can quickly block the connection between the feeder body 1 and the external irrigation system, avoid external water flow from interfering with internal operation during cleaning or maintenance, and ensure the independence and safety of system operation. At the same time, the isolation function of the first valve 103 provides the basic conditions for subsequent local pipeline flushing or premixing operation of the mixing tank 2. For example, when it is necessary to change the type of fertilizer, the external water source can be temporarily isolated by closing the first valve 103 to ensure the accuracy of the internal ratio of the mixing tank 2, thereby improving the control flexibility and reliability of the feeding process.
[0029] See Figure 1 , Figure 2 , Figure 3 A second valve 104 is connected to the infusion main pipe 101. The second valve 104 is connected to the mixing tank 2 through the first infusion pipe 106, realizing bidirectional liquid flow between the infusion main pipe 101 and the mixing tank 2. During the feeding operation, opening the second valve 104 can directly introduce the liquid in the main pipe into the mixing tank 2 for pre-dilution of fertilizer or secondary dissolution of residual fertilizer in the mixing tank, thereby improving fertilizer utilization. At the same time, it allows users to dynamically adjust the amount of liquid in the mixing tank 2 during the feeding process, such as adding clean water to adjust the fertilizer concentration or rinsing the inner wall of the mixing tank, thereby avoiding fertilizer deposition and ensuring that the active ingredients of the microbial water-soluble fertilizer are evenly distributed.
[0030] See Figure 1 , Figure 2 , Figure 3 The second valve 104 and the first valve 103 are opened to guide the liquid in the infusion main pipe 101 into the mixing tank 2. This allows for the directional guidance of the liquid in the infusion main pipe 101 into the mixing tank 2, enabling active replenishment or premixing of the mixing tank. For example, before starting the feeding process, clean water or low-concentration mother liquor can be pre-injected into the mixing tank 2. The water flow can promote fertilizer dissolution and reduce the need for manual stirring. At the same time, during the cleaning phase, this function can introduce high-pressure water from the main pipe into the mixing tank 2 to rinse the inner wall of the tank, further removing attached residues, improving cleaning efficiency, and reducing the risk of loss of microbial fertilizer activity.
[0031] See Figure 1 , Figure 2 , Figure 3 The second infusion pipe 107 is connected to a telescopic pipe 4 near the mixing tank 2. The telescopic pipe 4 is a rigid steel pipe, and the other end of the telescopic pipe 4 is connected to a filter screen 5. It can withstand the chemical corrosion of the fertilizer solution and adapt to changes in the liquid level in the mixing tank 2 through its telescopic structure. For example, when extracting high-concentration fertilizer, the length of the telescopic pipe 4 can be adjusted to allow the filter screen 5 to go deeper into the bottom of the mixing tank to avoid sucking in sediment impurities. When extracting low-concentration or clean fertilizer, the filter screen 5 can be raised to reduce the risk of clogging. At the same time, the rigid structure of the steel pipe, combined with the interception effect of the filter screen 5, can effectively separate undissolved particles or microbial carriers, ensuring the purity of the fertilizer solution entering the infusion main pipe 101 and ensuring the smooth operation of the irrigation system. Example 2:
[0032] See Figure 1 , Figure 2 , Figure 3An adjustment mechanism 3 is provided above the mixing tank 2 to adjust the height position of the filter screen frame 5 inside the mixing tank 2. The adjustment mechanism 3 includes a support frame 301, which is fixed above the mixing tank 2 in a cross structure. The telescopic tube 4 passes through the support frame 301 and is placed vertically at the central axis of the mixing tank 2. An adjustment block 302 is threaded to the outside of the telescopic tube 4, which realizes precise control of the height position of the filter screen frame 5 inside the mixing tank 2. For example, the vertical height can be adjusted according to the change of liquid level inside the mixing tank 2 to adapt to the fertilization needs of different crops. At the same time, the cross structure of the support frame 301 fixes the vertical posture of the telescopic tube 4, preventing it from shifting or vibrating under liquid impact, and ensuring that the filter screen frame 5 is always in the central axis position of the mixing tank 2, which maintains the suction stability and reduces the wear of components caused by tube shaking.
[0033] The implementation principle of this embodiment is as follows: During the feeding operation, the fourth valve 108, the third valve 105, and the first valve 103 are opened. Water flows through the main infusion pipe 101 and the Venturi pipe 102 of the feeder body 1. Due to the Venturi effect, a negative pressure is generated, drawing the microbial water-soluble fertilizer in the mixing tank 2 into the main infusion pipe 101 through the second infusion pipe 107 to complete the mixing and delivery. The filter screen frame 5 at the end of the second infusion pipe 107 filters the fertilizer solution. The depth of the filter screen frame 5 can be adjusted by adjusting the length of the telescopic pipe 4 extending into the mixing tank 2 by adjusting the adjusting block 302 of the adjusting mechanism 3. When the pipeline needs to be cleaned, the first valve 108 is kept in place. The fourth valve 108 is closed and the third valve 105 is opened, diverting the water flow from the main infusion pipe 101 to the venturi tube 102. Because the characteristic principle of the venturi tube is disrupted, the water flow directly washes the inner wall of the second infusion pipe 107 and the filter screen 5, removing residual fertilizer. This improves the protection of the second infusion pipe 107 and the filter screen 5, and facilitates the next fertilization operation. In addition, by controlling the flow of water through the first infusion pipe 106 and the second valve 104, liquid can be added to the mixing tank 2 for premixed fertilizer operation, thereby further improving the ease of use of the feeder.
