Description

Technical Field

[0001] This application relates to the field of agricultural machinery technology, and in particular to a liquid fertilizer application device. Background Technology

[0002] Crops require a large amount of nutrients during planting and growth, and fertilization is the most effective way to achieve this. Traditional fertilization methods involve applying solid fertilizer directly to the field. This method not only leads to excessively high fertilizer concentrations in the soil around the crop roots, causing seedling burn, but also results in uneven fertilization. Therefore, some existing methods dissolve solid fertilizer into a high-concentration liquid fertilizer, which is then introduced into irrigation pipes and applied to the field with the water. However, current methods of applying liquid fertilizer with irrigation water involve directly pipering the liquid fertilizer into the irrigation system. This method relies entirely on the turbulence of the water flow to mix the liquid fertilizer and water. Because the liquid fertilizer tends to flow along the inner wall of the irrigation pipe, where the flow rate is relatively slow, the fertilizer and water cannot fully mix before entering the irrigation network, leading to uneven fertilization and poor fertilization results.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0035] like Figure 1 As shown, this application provides a liquid fertilizer application device, including a mixing pipe 1, which is connected in sequence to a metering pump 10, a fertilizer dissolving tank 2, and a solid fertilizer storage silo 3.

[0036] The mixing pipe 1 is also connected in sequence to the water pump 20, the filter 4 and the clean water source 5 via a three-way valve 100;

[0037] The water pump 20 is also connected to the fertilizer dissolving tank 2 via a three-way valve 100;

[0038] The mixing pipe 1 is also connected to the drip irrigation network 6.

[0039] In use, switch the three-way valve 100 to connect the water pump 20 and the fertilizer dissolving tank 2 while blocking the mixing pipe 1. Start the water pump 20 to draw water from the clean water source 5, filter it through the filter 4, and then transfer it into the fertilizer dissolving tank 2. At the same time, the solid fertilizer stored in the solid fertilizer storage silo 3 is transported to the fertilizer dissolving tank 2 through the conveyor auger installed therein. Under the stirring of the stirring device installed in the fertilizer dissolving tank 2, it is quickly dissolved, and the dissolved fertilizer is also known as liquid fertilizer.

[0040] When applying liquid fertilizer, the state of the three-way valve 100 needs to be switched so that it connects the water pump 20 and the mixing pipe 1 while blocking the fertilizer dissolving tank 2. At this time, the clean water drawn by the water pump 20 is used as a carrier to enter the mixing pipe 1 and mix with the liquid fertilizer drawn by the metering pump 10. The mixed liquid fertilizer flows into the drip irrigation network 6 to drip irrigate the crops in the area where the drip irrigation network 6 is distributed.

[0041] This application provides a liquid fertilizer application device. A water pump 20 supplies clean water to a fertilizer dissolving tank 2, dissolving solid fertilizer supplied by a solid fertilizer storage silo 3 to obtain a liquid fertilizer of a certain concentration. The liquid fertilizer is then mixed with clean water in a mixing pipe 1 before being transported to the drip irrigation network 6 in the field for application to crops. This device, by using a mixing pipe 1 to mix the liquid fertilizer and clean water, improves the uniformity of the mixing between the liquid fertilizer and water, overcoming the drawbacks of traditional methods where liquid fertilizer is directly introduced into the water pipe, resulting in uneven mixing and poor fertilization effects.

[0042] like Figure 2 As shown, optionally, a water magnetizer 7 is also provided between the mixing pipe 1 and the drip irrigation network 6.

[0043] In this application, the main irrigation water sources, such as lake water, well water, and river water, are mostly large-molecule water. This type of water has poor activity and weak nutrient transport capacity, resulting in low crop yields, poor quality, and low economic benefits after irrigation. Furthermore, its fertilizer-dissolving capacity is limited, leading to low water and fertilizer utilization efficiency and significant fertilizer waste. Simultaneously, the low dissolved oxygen in the water results in insufficient dissolved oxygen in the soil, inhibiting root growth and severely limiting the full potential of crop production. A magnetic field can effectively break the hydrogen bonds between water molecules, thereby decomposing large water molecules into smaller ones, which helps enhance the water's effectiveness, promotes more efficient water and fertilizer integration, fully improves water and fertilizer utilization efficiency, helps plants better absorb nutrients, and improves the soil microenvironment. The water magnetizer 7 in this application uses a strong magnetic water processor with a magnetic induction intensity of 8000GS.

[0044] like Figure 3 As shown, optionally, the fertilizer dissolving tank 2 includes a tank body 21, and a grinder 22 is connected to the tank body 21;

[0045] The grinder 22 is connected to the solid fertilizer storage silo 3.

[0046] In this application, since solid fertilizers are mostly spherical particles with a relatively large particle size (about 1~3mm), they often require a long stirring time to dissolve after being added to water, which affects the fertilizer dissolution efficiency. A grinder 22 is set to pre-grind the solid waste particles into fine particles, which helps the solid fertilizer to dissolve.

[0047] like Figure 4 and Figure 5 As shown, optionally, the grinder 22 includes a body 221;

[0048] The main body 221 is provided with a grinding rotor 222 and a grinding chamber 223 that matches the grinding rotor 222;

[0049] The grinding chamber 223 is fixed to the inner wall of the body 221 and is open from top to bottom. The inner wall of the grinding chamber 223 is a frustum-shaped surface that is larger at the top and smaller at the bottom.

[0050] A motor 224 is connected to the bottom of the grinding rotor 222, and the motor 224 is connected to the inner wall of the body 221 through multiple fixing rods 225;

[0051] The top of the grinding rotor 222 is conical.

[0052] In this application, since the top of the grinding rotor 222 is conical, the solid waste particles entering the grinder 22 will flow to the side and enter the gap between the grinding rotor 222 and the grinding chamber 223. At this time, the motor 224 is turned on to drive the grinding rotor 222 to rotate. The grinding rotor 222 rotates relative to the inner wall of the grinding chamber 223, grinding and crushing the fertilizer particles that have entered the grinding chamber 223 and the grinding rotor 222 into fine powder. The fine powder obtained from grinding falls from the bottom of the body 221 (the body 221 is a barrel-shaped structure with open ends) into the fertilizer dissolving tank 2.

[0053] like Figure 4 and Figure 5 As shown, optionally, a mounting belt 2241 is fixedly connected to the outer periphery of the motor 224. The mounting belt 2241 is provided with a plurality of connecting holes 2201, and each connecting hole 2201 is connected to a fixing rod 225 in a one-to-one correspondence.

[0054] The fixing rod 225 passes through the side wall of the body 221 and is matched with the connecting hole 2201.

[0055] In this application, the connection between the fixing rod 225 and the connecting hole 2201 can be a detachable connection, such as a threaded connection (in which case the fixing rod 225 can be a bolt) or a snap-fit ​​connection. This connection method facilitates the easy disassembly of the motor 224, so as to facilitate the maintenance and replacement of the motor 224.

[0056] like Figure 4 and Figure 5As shown, optionally, the motor 224 is also covered with a frustum-shaped dust cover 226. The top of the dust cover 226 is close to the bottom of the grinding chamber 223 and has a through hole through which the power output shaft of the motor 224 passes, and is rotatably connected to the power output shaft of the motor 224.

[0057] The side wall of the dust cover 226 is penetrated by the fixing rod 225.

[0058] In this application, because the ground fertilizer particles are very fine, long-term use can cause fertilizer particles to adhere to the motor 224. These fertilizer particles are prone to corrosion of the motor 224 after absorbing moisture, which is detrimental to the long-term use of the grinder 22. Therefore, a dust cover 226 is needed to protect the motor 224. In this application, the dust cover 226 is frustum-shaped, that is, a frustum surface. The outer wall of this dust cover 226 can also guide the ground fertilizer.

[0059] Correspondingly, a sealing element, such as a sealing ring, is provided at the position where the fixing rod 225 passes through the side wall of the dust cover 226.

[0060] like Figure 6 As shown, optionally, the input end of the mixing pipe 1 is connected to the water pump 20, and the output end is connected to the drip irrigation network 6;

[0061] Multiple mixing blades 11 are installed inside the mixing pipe 1 at one end near the drip irrigation network 6;

[0062] The side of the mixing tube 1 near the input end is connected to the metering pump 10 via the fertilizer supply tube 12;

[0063] The fertilizer supply pipe 12 is a right-angle bend, and the horizontal section of the fertilizer supply pipe 12 is located inside the mixing pipe 1 and is coaxially arranged with the mixing pipe 1, and the output end is close to the mixing blade 11; the vertical section of the fertilizer supply pipe 12 passes through the side of the mixing pipe 1 and is connected to the metering pump 10.

[0064] In this application, during use, the clean water drawn by the water pump 20 is input into the mixing pipe 1 as a carrier and mixed with the liquid fertilizer drawn by the metering pump 10. When the liquid fertilizer and clean water are mixed, the liquid fertilizer drawn by the metering pump 10 enters the fertilizer supply pipe 12 and is output from the horizontal section of the fertilizer supply pipe 12, flowing into the clean water. When the clean water mixed with liquid fertilizer moves forward and passes through the mixing blades 11, the turbulence of the water flow is increased due to the obstruction of the mixing blades 11, forming turbulence in the water flow. The liquid fertilizer and clean water are uniformly mixed in this process.

[0065] A liquid fertilizer application device, the working process of which is as follows:

[0066] In use, switch the three-way valve 100 to connect the water pump 20 and the fertilizer dissolving tank 2 while blocking the mixing pipe 1. Start the water pump 20 to draw water from the clean water source 5, filter it through the filter 4, and then transfer it into the fertilizer dissolving tank 2. At the same time, the solid fertilizer stored in the solid fertilizer storage silo 3 is transported to the grinder 22 located on the upper part of the fertilizer dissolving tank 2 by the conveying auger installed therein. Since the top of the grinding rotor 222 is conical, the solid waste particles entering the grinder 22 will flow to the side and enter the gap between the grinding rotor 222 and the grinding chamber 223. At this time, the motor 224 is turned on to drive the grinding rotor 222 to rotate. The grinding rotor 222 rotates relative to the inner wall of the grinding chamber 223, grinding and crushing the fertilizer particles that enter the grinding chamber 223 and the grinding rotor 222 into fine powder. The fine powder obtained from grinding falls from the bottom of the body 221 (the body 221 is a barrel-shaped structure with open ends) into the fertilizer dissolving tank 2. Under the stirring of the stirring device set in the fertilizer dissolving tank 2, it is quickly dissolved, and the dissolved fertilizer is also known as liquid fertilizer.

[0067] When applying liquid fertilizer, the state of the three-way valve 100 needs to be switched so that it connects the water pump 20 and the mixing pipe 1 while blocking the fertilizer dissolving tank 2. At this time, the clean water drawn by the water pump 20 is used as a carrier to enter the mixing pipe 1 and mix with the liquid fertilizer drawn by the metering pump 10. When the liquid fertilizer and clean water are mixed, the liquid fertilizer drawn by the metering pump 10 enters the fertilizer supply pipe 12 and is output from the horizontal section of the fertilizer supply pipe 12 into the clean water. When the clean water mixed with liquid fertilizer moves forward and passes through the mixing blades 11, the turbulence of the water flow is increased due to the obstruction of the mixing blades 11, forming turbulence in the water flow. The liquid fertilizer and clean water are uniformly mixed in this process. After being magnetized by the water magnetizer 7, the mixed liquid fertilizer flows into the drip irrigation network 6 to drip irrigate the crops in the area where the drip irrigation network 6 is distributed.
