Description

Technical Field

[0001] This utility model relates to the technical field of agricultural planting, and in particular to an intelligent irrigation device for integrated water and fertilizer management of crops. Background Technology

[0002] Traditional water-fertilizer irrigation methods for crops suffer from problems such as water waste, uneven fertilization, and high labor intensity. With the development of technology, it has been discovered that integrated water and fertilizer irrigation can effectively solve these problems, thereby improving crop yield and quality and reducing agricultural production costs.

[0003] Integrated water and fertilizer irrigation involves mixing soluble solid or liquid fertilizers according to soil nutrient content and crop nutrient requirements, and then supplying the solution to crops via a controlled pipeline system. Current integrated water and fertilizer irrigation equipment typically consists of multiple large-capacity mixing containers, making the overall system bulky. This makes it difficult to ensure that the prepared fertilizer solution is completely used each time. If not used completely, the fertilizer solution in the containers and pipelines is prone to recrystallization, leading to blockages. Summary of the Invention

[0004] The purpose of this utility model is to provide an intelligent irrigation device for integrated water and fertilizer management of crops, so as to solve the problem that the existing integrated water and fertilizer management irrigation system cannot consume the prepared fertilizer solution in time, which easily causes blockage.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0026] Examples, such as Figures 1 to 6 As shown, an intelligent irrigation device integrating water and fertilizer for crops includes several fertilizer storage bins 1, a proportioning mechanism, and a mixing device. The bottom of each fertilizer storage bin is connected to the proportioning mechanism. The proportioning mechanism includes a feeding roller 13, on which a feeding groove 14 is provided. The size of the feeding groove 14 is adjustable. By adjusting the size of the feeding groove 14 under different fertilizer storage bins, the feeding ratio between different fertilizers can be adjusted each time, thereby realizing the real-time proportioning of different fertilizers.

[0027] The mixing device includes a first mixing mechanism and a second mixing mechanism. The top of the first mixing mechanism is connected to the proportioning mechanism, and the bottom of the first mixing mechanism is connected to the second mixing mechanism. The first mixing mechanism is used to mix fertilizer with a certain amount of water in a certain proportion to produce a high-concentration fertilizer solution. The second mixing mechanism is used to mix the high-concentration fertilizer solution with water to form a water-fertilizer that can be directly irrigated.

[0028] In this embodiment, the proportioning mechanism further includes a proportioning tube shell 2 and a movable block 18. The feeding roller 13 is rotatably disposed inside the proportioning tube shell 2. The proportioning tube shell 2 is fixed to the body of the dispensing motor 9. The motor shaft of the dispensing motor 9 is fixedly connected to the feeding roller 13. The feeding roller 13 has an elongated groove. The movable block 18 slides in the elongated groove with the feeding roller 13. The feeding roller 13 and the proportioning tube shell 2 cooperate to form a feeding groove 14. By moving the feeding roller 13, the size of the feeding groove 14 can be changed. By proportionally changing the size of the feeding groove 14 below different fertilizer storage tanks 1, the proportion of different fertilizers can be adjusted with each rotation of the feeding roller 13.

[0029] Furthermore, an annular groove 17 is provided on the inner wall of the proportioning tube shell 2 near the end of the proportioning tube shell 2. An air guide pipe 16 is connected to the annular groove 17. By injecting or extracting gas into the annular groove 17 through the air guide pipe 16, the position of the movable block 18 can be changed, thereby realizing the automatic adjustment of the size of the material taking trough 14.

[0030] In this embodiment, the upper end of the mixing tube shell 2 is provided with a feed inlet 202, and the lower end of the mixing tube shell 2 is provided with a discharge outlet 201. The feed inlet 202 is connected to the bottom of the fertilizer storage tank 1 through a feed connecting pipe 15, and the discharge outlet 201 is connected to the top of the fertilizer liquid tank 3 through a discharge connecting pipe 12. When the feeding groove 14 on the feeding roller 13 rotates to the forward feed connecting pipe 15, the fertilizer in the fertilizer storage tank 1 is transferred from the feed connecting pipe 15 into the feeding groove 14. Then, the feeding motor 9 controls the feeding groove 14 to rotate to face the discharge connecting pipe 12. At this time, the fertilizer in the feeding groove 14 will fall into the fertilizer liquid tank 3, thereby completing the mixing of fertilizer and liquid in the fertilizer liquid tank 3.

[0031] In this embodiment, the first mixing mechanism includes a stirring motor 11, a stirring mechanism, a fertilizer solution tank 3, and a partition 19. The stirring motor 11 is fixed to the top of the fertilizer solution tank 3. The partition 19 is located inside the fertilizer solution tank 3 and divides the fertilizer solution tank 3 into a first receiving cavity and a second receiving cavity. The first receiving cavity is located above the second receiving cavity. The first receiving cavity is provided with a communication port, and a door 23 is provided at the communication port. The door 23 is used to control the communication state between the first receiving cavity and the second receiving cavity.

[0032] Furthermore, the stirring mechanism includes a stirring shaft 20, a first stirrer 21, and a second stirrer 22. The first stirrer 21 is located in the first receiving cavity, and the second stirrer 22 is located in the second receiving cavity. The motor shaft of the stirring motor 11 is fixedly connected to the stirring shaft 20. Both the first stirrer 21 and the second stirrer 22 are fixedly connected to the stirring shaft 20. By controlling the rotation of the stirring motor 11, the rotation of the stirring shaft 20 can be controlled, thereby controlling the first stirrer 21 and the second stirrer 22 to stir simultaneously.

[0033] Advantageously, an electromagnet 24 is also fixed on the partition 19, and the pin of the electromagnet 24 is fixed to the hatch 23. The hatch 23 can be controlled to open and close the communication port by means of the electromagnet 24.

[0034] In this embodiment, the second mixing mechanism includes a mixing valve 4 and an inlet pipe connector 5. The mixing valve 4 is connected to the bottom of the fertilizer tank 3, and the inlet pipe connector 5 is also connected to the mixing valve 4. The mixing valve 4 is used to mix the fertilizer in the fertilizer tank 3 with the irrigation water connected to the inlet pipe connector 5, thereby diluting the fertilizer in the fertilizer tank 3 to the required irrigation concentration.

[0035] In this embodiment, the first accommodating cavity is also connected to one end of the fertilizer solution mixing water inlet pipe 7, and the other end of the fertilizer solution mixing water inlet pipe 7 is connected to the water inlet pipe connector 5. A solenoid valve 10 is also connected to the fertilizer solution mixing water inlet pipe 7, and the solenoid valve 10 controls whether water is injected into the partition 19.

[0036] Advantageously, the bottom of the fertilizer storage tank 1 and the bottom of the fertilizer liquid tank 3 are both funnel-shaped.

[0037] In use, first adjust the size of the feeding trough 14 under each fertilizer storage tank 1, then move the entire device to the vicinity of the farmland that needs irrigation, connect the inlet pipe connector 5 to the irrigation water pipe, and then connect the outlet pipe connector 6 to the sprinkler irrigation water pipe of the farmland. Place the corresponding type of fertilizer in each tank, and the mixing motor 9 rotates to put the fertilizer into the first container chamber in proportion. Water is then injected into the first container chamber through the fertilizer solution mixing inlet pipe 7. The first stirrer 21 is used to stir and prepare a high concentration of fertilizer solution. The partition 19 is equipped with a level gauge. After the level gauge detects that the water level has reached the designated position, the hatch 23 is opened to put the fertilizer solution into the second container chamber. The fertilizer solution in the second container chamber is mixed with the water at the inlet pipe connector 5 through the mixing valve 4, thereby irrigating the farmland.

[0038] After the hatch 23 is opened to release the fertilizer solution into the second receiving chamber, the hatch 23 closes again, and the fertilizer solution is mixed in the first receiving chamber to ensure an uninterrupted supply of fertilizer solution in the second receiving chamber. Overall, this allows for the immediate preparation and use of fertilizer solution without causing clogging of the device and pipelines due to fertilizer solution recrystallization.

[0039] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
