Description

Technical Field

[0001] The present invention relates to the technical field of water and fertilizer machines, and in particular to a constant flow type fertilizer and water integrated machine and a use method thereof. Background Art

[0002] In modern agriculture, precision fertilization and irrigation are key links in improving crop yield and quality. Traditional fertilizer and water management methods often rely on manual operations, which are not only time-consuming and labor-intensive, but also difficult to achieve precise control and uniform distribution of fertilizer and water. This may lead to problems such as unbalanced crop nutrition, waste of water resources, and environmental pollution.

[0003] With the continuous advancement of agricultural technology, automated and intelligent fertilizer and water management systems have gradually become a research hotspot in the agricultural field. Such systems usually use components such as sensors, controllers and actuators to achieve real-time monitoring and automatic adjustment of parameters such as fertilizer and water flow and concentration, thereby achieving the purpose of precise fertilization and irrigation.

[0004] However, existing fertilizer and water management systems still have some limitations in design and function. For example, some systems cannot achieve constant flow output of fertilizer and water, resulting in uneven fertilization; some systems lack intelligent control and require frequent manual adjustment of parameters; and some systems cannot adapt to the needs of crops of different types and growth stages and lack flexibility and scalability.

[0005] At present, there is a kind of integrated fertilizer and water machine on the market, more accurately called water-fertilizer integrated machine, which is a new agricultural technology equipment that combines irrigation and fertilization. It mixes soluble solid or liquid fertilizer with water in a certain proportion to form fertilizer liquid, and then uses a pressure system (or natural terrain drop) and a controllable pipeline system to transport the fertilizer liquid together with irrigation water through pipelines and infiltrate the root development and growth area of ​​crops. However, the existing integrated fertilizer and water machine has many shortcomings: 1. Traditional integrated fertilizer and water machines generally use solenoid valves to control fertilizer and water. The solenoid valves work in two states: on and off. Fertilizer and water are intermittent, and it is impossible to achieve uniform and accurate fertilization. 2. Traditional integrated fertilizer and water machines generally support three types of fertilizers and water: A fertilizer, B fertilizer, and acid fertilizer. They are generally used for fertilizing small culture media. However, for large-scale field irrigation, many types of fertilizers and water are required in large quantities. Traditional integrated fertilizer and water machines cannot meet these needs. 3. Traditional fertilizer and water machines generally output according to EC value and PH value, but ordinary users do not understand EC value and PH value and cannot intuitively know the amount of fertilizer to be applied; 4. The traditional fertilizer and water integrated machine is complicated to operate, requires high professional knowledge from users, and has high operation and maintenance costs.

[0006] Based on this, the applicant proposed a constant flow fertilizer and water integrated machine and its use method to solve the above technical problems. Summary of the invention

Based on the embodiments described in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The fertilizer water flows through the filter 2 through the input pipe 1 and then passes through the two-way control valve 3. The Hall flowmeter 4 detects the real-time fertilizer water flow and feeds back a signal to the controller. The controller adjusts the opening of the two-way control valve 3 according to the signal and the preset parameters, so as to realize the constant flow output of the fertilizer water. After each fertilizer water flows through the two-way control valve 3 corresponding to the fertilizer water passage unit, it is generally collected into the collection pipe 7 through the corresponding output pipe 6. The collection pipe 7 is connected to a water pump 8, and the mixed fertilizer water in the collection pipe 7 is made to flow out from the main waterway 9 through the water pump 8. The collection pipe 7 is also provided with a plurality of clean water pipes 11, and the clean water flows into the collection pipe 7 from the clean water pipe 11, and is mixed with the fertilizer water of each route to form the mixed fertilizer water.

[0030] The present invention adopts a two-way control valve (such as an electric ball valve) to replace the traditional solenoid valve, and adjusts the valve opening in real time through the controller, thereby realizing continuous and stepless regulation of the fertilizer and water flow rate. This design ensures the constant flow output of fertilizer and water, avoids the problem of intermittent fertilizer and water, realizes precise fertilization, and improves the nutrient absorption efficiency and yield quality of crops.

[0031] The present invention also includes a master controller 10, which is connected to the controller on each of the fertilizer and water passage units. The preset parameters of each controller are set through the master controller 10. Different from the traditional fertilizer and water integrated machine that outputs according to EC value and PH value, the present invention allows the user to directly set the fertilization time parameter and the fertilization flow parameter (or the barrel diameter, water level height and fertilization time parameter) through the master controller. The system automatically calculates and displays the fertilizer amount according to the set parameters, so that the user can understand and control the fertilization process more intuitively, reducing the difficulty of operation and the requirements of professional knowledge.

[0032] It also includes a plurality of fertilizer barrels, each of the fertilizer-water passage units corresponds to a fertilizer barrel, the input pipe 1 is connected to the fertilizer barrel, a water level monitoring sensor is arranged in the fertilizer barrel, the water level monitoring sensor is connected to the master controller 10, an electric agitator is also arranged in the fertilizer barrel, the electric agitator is connected to the master controller 10, the water level monitoring sensor and the electric agitator are both existing technologies, and there are various specifications available on the market, and their specific structure will not be described in detail here, and those skilled in the art can order or customize them according to their needs.

[0033] The fertilizer and water integrated machine of the present invention is designed with multiple fertilizer and water passage units, each unit can be independently controlled and corresponds to a fertilizer barrel, thereby supporting the mixing and output of multiple types of fertilizers and water. This design not only meets the needs of large quantities and types of fertilizers and water for field irrigation, but also improves the flexibility and scalability of the system. The present invention integrates components such as sensors, controllers and actuators to achieve real-time monitoring and automatic adjustment of parameters such as fertilizer and water flow and concentration. At the same time, the master controller can also receive signals from water level monitoring sensors and electric stirrers to achieve intelligent management and maintenance. This design not only improves the stability and reliability of the system, but also reduces operation and maintenance costs and extends the service life of the equipment.

[0034] A constant-flow integrated fertilizer and water machine of the present application supports more than 9 types of fertilizers and water, such as N fertilizer, NPK fertilizer, K2SO4, fruit N, fruit Ca, fruit MgSO4, fruit K, CaO fertilizer, B fertilizer and other soluble fertilizers, which can better meet the needs of field irrigation and can be applied as soon as the fertilizer is dissolved. The present embodiment provides a 9-channel constant-flow integrated fertilizer and water machine, and the volume of each fertilizer barrel is not less than 500L.

[0035] A method for using a constant-flow integrated fertilizer and water machine comprises the following steps: Step A: Debugging: Entering the equipment debugging mode through the master controller 10, respectively debugging the two-way control valve 3 and the electric stirrer in each fertilizer and water passage unit, and exiting after the debugging is completed; Step B: Material preparation: Prepare several kinds of fertilizers required, put them into corresponding fertilizer barrels, and connect the fertilizer barrels with corresponding input pipes 1; Step C: Setting parameters: Setting the preset parameters of each fertilizer and water passage unit through the master controller 10; Step D: Constant-flow fertilization: Starting the equipment, various kinds of fertilizer and water enter the collection pipe 7 through the corresponding fertilizer and water passage units at a constant flow according to the preset parameters, and flow out from the main waterway 9 after being pressurized by the water pump 8; Step E: Clean water irrigation: After the fertilizer and water irrigation is completed, each fertilizer and water passage unit is automatically disconnected, and then the clean water flows out through the main waterway 9 for irrigation for a certain period of time.

[0036] There are two modes for the preset parameters in step C: Mode 1: Flow mode: The preset parameters in this mode include fertilization time parameters and fertilization flow parameters. When the whole equipment is running, each fertilizer and water channel runs according to the corresponding set fertilization flow parameters, and the running time is the set fertilization time parameters.

[0037] Mode 2: Time mode: The preset parameters in this mode include barrel diameter parameters, water level parameters and fertilization time parameters. The master controller 10 calculates and displays the fertilization flow value according to the set parameter values. When the whole equipment is running, each fertilizer and water channel runs according to the corresponding calculated fertilization flow value, and the running time is the set fertilization time parameter.

[0038] The fertilization time parameter provided in this embodiment is 20 minutes, and the clean water irrigation time after the fertilization in step E is 30 minutes.

[0039] The debugging of the two-way control valve 3 in step A includes manually opening the valve, manually stopping the valve and manually closing the valve; the debugging of the electric agitator includes manually starting stirring and manually stopping stirring. After the debugging is completed and the equipment is confirmed to be normal, the debugging mode is exited.

[0040] In step B, the fertilizer in the fertilizer barrel needs to be stirred by an electric stirrer to make the fertilizer evenly dissolved, and then the electric stirrer is stopped. After the liquid level is stable, the water level monitoring sensor monitors the water level height to ensure the accuracy of the corresponding total amount of fertilizer; when constant flow fertilization is performed in step D, the water level monitoring sensor monitors the liquid level height in the fertilizer barrel in real time.

[0041] In order to better operate, the master controller 10 is provided with a display screen, and the operation can be clearly, intuitively and easily performed through the human-computer interaction interface. The human-computer interaction interface is provided with sub-control interfaces of various fertilizers and water and a master control interface of the whole equipment. Technical personnel in this field can design this part according to existing technology and actual needs, including UI interface, corresponding program programming, etc., which will not be elaborated here.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive from any point of view.

Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
