Description

Technical Field

[0001] This utility model relates to the field of nutrient solution addition technology, specifically a nutrient solution addition device for farms. Background Technology

[0002] Farm nutrient solution is a scientifically formulated water-soluble liquid fertilizer that typically contains macronutrients such as nitrogen, phosphorus, and potassium, as well as micronutrients such as iron, zinc, and manganese, which are essential for crop growth. These components are formulated according to the needs of different growth stages of crops and can be directly absorbed by the plant roots, thereby promoting growth, improving stress resistance, and improving the soil environment.

[0003] Nutrient solutions are typically prepared by mixing and blending raw materials, and then stored in a storage tank for use. Adding nutrient solution requires manual preparation and addition, making the entire process relatively cumbersome. Automatic addition equipment utilizes a pump system to draw the raw materials into the storage tank for mixing. In practice, only liquid level monitoring is needed to control the pump's operation. However, this method has a drawback: if the liquid level in the storage tank drops below a preset value while the nutrient solution is being used, the raw materials are directly drawn into the tank without effective mixing, resulting in uneven mixing. Therefore, without independent mixing, raw materials are usually not added when the nutrient solution is being used, limiting the capabilities of automatic addition equipment. Utility Model Content

[0004] The purpose of this invention is to provide a nutrient solution addition device for farms to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a storage tank and a raw material tank. A feed pipe is fixed at equal intervals at the upper end of the storage tank. A connecting pipe is fixed between the feed pipe and the raw material tank. A pump is installed inside the raw material tank at a position corresponding to the connecting pipe. The storage tank is divided into a storage chamber and a mixing chamber by a partition. A stirring rod is rotatably connected inside the mixing chamber. A drive motor that drives the stirring rod to rotate is fixed at the upper end of the storage tank. An inner drain pipe is fixed on the partition. A liquid level sensor is fixed at the bottom center of the partition.

[0006] Preferably, both the inner drain pipe and the feed pipe are fixed with solenoid valves, and the connecting pipe is equipped with a flow meter.

[0007] Preferably, a filter screen is fixed inside the storage cavity. The filter screen has a ring structure and an inner support plate is fixed in the middle.

[0008] Preferably, a support column is fixed to the outer periphery of the bottom of the liquid storage tank, and a discharge pipe is fixed to the middle position of the bottom of the liquid storage tank.

[0009] Preferably, the liquid storage tank has air holes on its side wall and top, with the air holes on the side wall located above the storage chamber.

[0010] Preferably, a dustproof net is fixed to the outer wall of the liquid storage tank at a position aligned with the air vent.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by using a partition to divide the liquid storage tank into a stirring chamber and a storage chamber, the raw materials can be mixed independently after entering before being injected into the storage chamber for use. This avoids the situation where the raw materials cannot be injected and mixed during the drainage process, thus improving the practicality of the automatic addition device.

[0016] 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.

[0017] Please see Figure 1-3This utility model provides a technical solution: including a storage tank 1 and a raw material tank 2. A feed pipe 11 is fixed at equal intervals on the upper end of the storage tank 1. A connecting pipe 3 is fixed between the feed pipe 11 and the raw material tank 2. A liquid pump 21 is installed in the raw material tank 2 at a position corresponding to the connecting pipe 3. The storage tank 1 is divided into a storage chamber 6 and a mixing chamber 5 by a partition 4. A stirring rod 51 is rotatably connected in the mixing chamber 5. A drive motor 52 that drives the stirring rod 51 to rotate is fixed on the upper end of the storage tank 1. An inner drain pipe is fixed on the partition 4. A liquid level sensor 41 is fixed at the middle position of the bottom of the partition 4.

[0018] Solenoid valves are fixed on both the inner drain pipe and the feed pipe 11. A flow meter 31 is installed on the connecting pipe 3. A filter screen 42 is fixed inside the storage chamber 6. The filter screen 42 has a ring structure and an inner support plate 43 is fixed in the middle. A support column 12 is fixed on the outer periphery of the bottom of the liquid storage tank 1. A discharge pipe 13 is fixed in the middle of the bottom of the liquid storage tank 1.

[0019] Air holes 14 are provided on the side wall and top of the liquid storage tank 1. The air holes 14 on the side wall of the liquid storage tank 1 are located above the storage chamber 6. A dustproof net 15 is fixed on the outer side wall of the liquid storage tank 1 at a position aligned with the air holes 14.

[0020] Working principle: First, the entire device is connected to an external power source. Using the level sensor 41, the liquid level of the nutrient solution in the storage chamber 6 can be accurately monitored. When the liquid level falls below the preset value, the pump 21 is driven to extract the raw materials. The stock solution and water used to prepare the nutrient solution are injected into the mixing chamber 5 through different feed pipes 11. Then, the drive motor 52 drives the stirring rod 51 to rotate, mixing the various raw materials thoroughly and evenly. The mixture is then discharged into the storage chamber 6 through the inner drain pipe. Throughout the process, the raw materials will not mix with the existing nutrient solution before they are evenly mixed. Therefore, even if the nutrient solution in the storage chamber 6 is used, it will not affect the preparation of the nutrient solution. This not only achieves automatic addition but also increases the practicality of the entire addition device. During the process, the flow meter 31 and the solenoid valve work together to accurately control the injection volume of different raw materials. Simultaneously, the filter screen 42 can filter particulate matter from the incoming nutrient solution. Furthermore, the vents 14 on the top and side walls ensure pressure balance between the mixing chamber 5 and the storage chamber 6, guaranteeing normal liquid injection and discharge.
