Description

Technical Field

[0001] This utility model relates to the field of agricultural fertilization equipment technology, and in particular to a fertilization device for precise quantitative application of liquid fertilizer. Background Technology

[0002] Fertilization refers to agricultural techniques that involve applying fertilizers to the soil or spraying them on plants to provide the nutrients needed by the plants and to maintain and improve soil fertility. The main factors for fertilization are soil fertility level, crop type, target yield, climate environment, and fertilizer characteristics, in order to select appropriate fertilizers, estimate the required amount of fertilizer, and determine the timing and method of fertilization.

[0003] The common fertilization method for crops such as wheat, corn, peanuts, soybeans, and sweet potatoes is to mix fertilizer with water to form a solution and then apply it through drip irrigation, sprinkler irrigation, etc. However, the amount of fertilizer applied cannot be accurately controlled quantitatively. Too much liquid fertilizer will lead to waste, while too little liquid fertilizer will not meet the growth needs of seedlings. Based on this, this application proposes a fertilization device for precise quantitative application of liquid fertilizer, which can solve the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fertilization device for precise quantitative application of liquid fertilizer.

[0006] Optionally, the fertilizer tank has an installation hole at the bottom, and an air valve is installed inside it.

[0007] Optionally, a fixed cylinder is installed at the center of the lower part of the fertilizer tank, and a sealing ring is installed on its inner wall. A cylinder is installed below the fixed cylinder, and the output end of the cylinder is installed together with the bottom of the piston.

[0008] Optionally, a fixed pipe is installed on one side of the top surface of the fertilizer tank, and an injection valve is installed on it.

[0009] Optionally, an installation groove is provided at the center of the top surface of the fertilizer tank, and the first liquid level gauge is installed in the installation groove.

[0010] This utility model has the following advantages:

[0011] This liquid fertilizer application device uses a fertilizer tank as its main body. Inside the fertilizer tank, there is a piston that can move up and down. When the piston moves upward, the liquid fertilizer is discharged from the outlet pipe at the top of the fertilizer tank. Liquid level gauges are installed on the top of the fertilizer tank and on the piston. When used together, the liquid level in the fertilizer tank can be accurately measured. At the same time, a liquid level gauge is also installed on the piston, which runs through the fertilizer tank for easy viewing by the staff.

[0012] An air valve is installed at the bottom of the fertilizer tank to maintain the pressure balance inside the tank. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0019] like Figures 1 to 4 As shown, a fertilization device for precise quantitative application of liquid fertilizer includes a fertilizer tank 1. Inside the fertilizer tank 1, a piston 7 that can reciprocate up and down is installed. Multiple circumferentially arrayed liquid outlet pipes 13 are installed on the upper part of the fertilizer tank 1, and each of them is equipped with a liquid outlet valve 3 at its outer end. A first liquid level gauge 5 is installed on the upper part of the fertilizer tank 1. A second liquid level gauge 10 is installed on the top surface of the piston 7. A liquid level scale 4 is installed on one side of the top surface of the piston 7, which penetrates the fertilizer tank 1.

[0020] As an optional technical solution of this utility model, the fertilizer tank 1 has an installation hole 14 at the bottom, and an air valve 9 is installed inside it. When the piston 7 moves, air can enter and exit through the air valve 9, so that the internal air pressure will be balanced.

[0021] As an optional technical solution of this utility model, a fixed cylinder 15 is installed in the middle position below the fertilizer tank 1, and a sealing ring 8 is installed on its inner wall. A cylinder 2 is installed below the fixed cylinder 15. The output end of the cylinder 2 is installed together with the bottom of the piston 7. The cylinder 2 can drive the piston 7 to move, and the sealing ring 8 can improve the sealing between the components.

[0022] As an optional technical solution of this utility model, a fixed pipe 11 is installed on one side of the top surface of the fertilizer tank 1, and an injection valve 6 is installed on it, so that the user can pour liquid fertilizer into the tank from this point.

[0023] As an optional technical solution of this utility model, an installation groove 12 is provided in the middle of the top surface of the fertilizer tank 1, and the first liquid level gauge 5 is installed in the installation groove 12, which facilitates the installation and disassembly of the first liquid level gauge 5.

[0024] In summary, the features, assembly method, usage process, and functions of each component in this utility model are as follows: The fertilizer tank 1 serves as the main body of the device. Inside the fertilizer tank 1, a piston 7 capable of reciprocating up and down is installed. The upward movement of the piston 7 allows liquid fertilizer to be discharged from the outlet pipe 13 above the fertilizer tank 1. A level gauge is installed above the fertilizer tank 1 and on the piston 7. The two work together to accurately measure the liquid level in the fertilizer tank 1. A level gauge 4 is also installed on the piston 7, penetrating the fertilizer tank 1 for easy viewing by staff. An air valve 9 is installed below the fertilizer tank 1 to maintain pressure balance inside the fertilizer tank 1.
