Description

Technical Field

[0001] The utility model relates to the technical field of fertilization equipment, in particular to a high-efficiency fertilization device for greenhouse vegetables. Background Art

[0002] There are many kinds of vegetables grown in greenhouses, and their liquid fertilizer application requirements are also different. Leafy vegetables such as cabbage and green vegetables mainly rely on nitrogen fertilizer during their growth process. At the same time, phosphorus and potassium fertilizers need to be increased during the peak growth period to promote the lush growth of leaves. Fruiting vegetables, such as melons, solanaceae and beans, have different nutrient requirements during their growth stages. More nitrogen fertilizer is required during the seedling stage, but care should be taken to control the amount to avoid excessive growth. After entering the reproductive growth period, it is necessary to increase the application of phosphorus fertilizer and appropriately reduce nitrogen fertilizer to promote the development of flowers and fruits. Root vegetables, such as radishes and carrots, need more nitrogen fertilizer in the early growth stage to form large green leaves, and more potassium fertilizer in the middle and late growth stages to promote the expansion and development of fleshy roots. Therefore, in the process of greenhouse vegetable cultivation, liquid fertilizer should be applied scientifically and reasonably according to the type and growth stage of vegetables to meet their nutrient needs, promote healthy growth, and increase yield and quality.

[0003] There are indeed significant differences in the fertilization methods and fertilizers required for different greenhouse vegetables. For example, leafy vegetables often supplement trace elements by foliar spraying, while root vegetables prefer root topdressing to promote root development. This requirement for precise fertilization has challenged traditional fertilization methods. At present, sprayer spraying and drone spraying are two common fertilization methods. However, they both have certain defects. Although the sprayer spraying method is easy to operate, the fertilization efficiency is low and it is easily affected by human factors, resulting in uneven fertilization, which in turn affects the growth of vegetables. In addition, the sprayer spraying method also has the problem of liquid waste, which increases production costs. The drone spraying method has improved fertilization efficiency, but its operation is relatively difficult and requires high skills for operators. At the same time, the drone spraying method also has the problem of insufficient fertilization accuracy, especially at different stages of vegetable growth, the fertilizer requirement and fertilization method have changed, and the drone spraying method is difficult to fully adapt to. In addition, the cost of the drone spraying method is also relatively high, which may not be economical and practical for small vegetable greenhouses. Utility Model Content

The battery provides a stable and reliable power supply for the entire system, ensuring the normal operation of each component, and the circuit control component is responsible for receiving operating instructions and accurately controlling each component according to the instructions. The three key components, the first solenoid valve 52, the second solenoid valve 8 and the pump body 54, are electrically connected to the battery and the circuit control component, which means that, The circuit control component can monitor and control the working status of these three components in real time. For example, when it is necessary to extract a certain liquid fertilizer for fertilization, the circuit control component will receive the corresponding instruction and immediately open the corresponding first solenoid valve 52, and start the pump body 54 to pump liquid. When the liquid fertilizer needs to be accurately sprayed on different parts of the vegetables, the circuit control component will open the corresponding second solenoid valve 8 according to the preset program or the operator's instructions to ensure that the liquid fertilizer can flow smoothly to the target fertilization position. In addition, the electrical control cabinet 9 also has certain safety protection functions. When the system detects that a component has a fault or abnormal situation, the circuit control component will immediately cut off the power supply of the component to prevent the fault from expanding or causing a safety accident. At the same time, the electrical control cabinet 9 can also record the working status and fault information of each component, providing important reference data for subsequent maintenance and care.

[0079] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 , Figure 4 As shown; a receiving gap 10 is opened on the surface of the covering shell 4, wherein the covering shell 4 is placed on the outside of the vegetables through the receiving gap 10. The design of the receiving gap 10 solves the obstacles that the covering shell 4 may encounter when covering the vegetables. When the covering shell 4 needs to be placed on the outside of the vegetable group, the receiving gap 10 allows the stems or thicker branches of the vegetables to pass through without being hindered. In this way, the covering shell 4 can fit tightly around the vegetable group to form a relatively closed fertilization space, ensuring that the liquid fertilizer will not spread at will during the spraying process, but can accurately act on the leaf surface, side and rhizome of the vegetables.

[0080] The specific working principle of the utility model of a greenhouse vegetable efficient fertilization device is as follows:

[0081] The whole device is installed in the greenhouse, and the shaped frame 1 is ensured to be firmly set in the greenhouse soil as the basic support structure of the whole device. Then, the connecting member 2 is installed on the shaped frame 1. Through the combination of the track 21 and the sliding member 22, the connecting member 2 can be flexibly moved on the shaped frame 1 to meet the fertilization needs of different rows of greenhouse vegetables.

[0082] Then, the liquid fertilizer storage tank 3 is installed on the connecting member 2, and the height of the liquid fertilizer storage tank 3 is adjusted by the height adjusting member 23, so that it is suspended at a suitable position, ensuring that the housing 4 can tightly cover the outside of the vegetables and avoid the diffusion of liquid fertilizer during fertilization. The adjustment process of the height adjusting member 23 includes selecting the appropriate length of the first screw rod 233 and the second screw rod 235, connecting and adjusting the length through the threaded adjustment sleeve 234, and finally fixing the U-shaped ring to the protrusion through the first bolt and the second bolt;

[0083] In the liquid fertilizer storage tank 3, a partition 6 is used to divide it into several liquid fertilizer filling areas, each area can be filled with different types of liquid fertilizers, and liquid fertilizer is added to each liquid fertilizer filling area through the filling port, and the liquid level observation window 7 is observed to ensure that the liquid fertilizer is sufficient;

[0084] The electric control cabinet 9 will open the corresponding first solenoid valve 52 and second solenoid valve 8 according to the preset program, and the pump body 54 will start working to extract the liquid fertilizer from the liquid fertilizer storage tank 3. After being pressurized by the fertilizer temporary storage shell 53 and the pump body 54, according to the actual situation, the liquid fertilizer is accurately sprayed on the leaf surface or side and root and stem parts of the vegetables through the multi-dimensional spraying component 55, and finally the sliding member 22 is pushed to move along the length direction of the track 21, so that the vegetables planted in each row in the greenhouse can be fertilized efficiently and accurately.
