Description

Technical Field

[0001] The present invention relates to the technical field of agricultural equipment technology, and in particular to fertilizer application equipment based on spectral detection. Background Art

[0002] In the development process of modern agriculture, precision agriculture technology is receiving increasing attention. Its purpose is to significantly increase crop yields, minimize resource waste, and at the same time play a good protective role in the ecological environment. Spectral detection technology can quickly obtain nutritional status information of soil and crops by analyzing the spectral characteristics of soil and crops. By detecting the spectral characteristics of crop leaves, soil, etc., it can indirectly analyze their nutritional status and the type and amount of fertilizer required, which provides the possibility for precision fertilization.

[0003] The working principle of fertilizer application equipment is usually to take out fertilizer from the storage container in a quantitative manner, then mix the fertilizer with a certain amount of water, and then atomize and spray the liquid fertilizer with the help of a nozzle. Its purpose is to achieve uniform, appropriate and timely application of fertilizer according to different crop needs and soil conditions.

[0004] When the fertilizer application equipment with spectral detection draws water from the water source and mixes it with fertilizer, impurities in the water will merge with the fertilizer, changing the chemical properties of the fertilizer and affecting its effectiveness and stability. In addition, fertilizer storage tanks are prone to precipitation or crystallization after long-term storage, resulting in inconsistent fertilizer concentrations, which can easily lead to excessive or insufficient fertilization, affecting crop growth and farmland yield quality. Finally, the mixing tank cannot be cleaned by simple rinsing after mixing, and residual attachments will contaminate subsequent fertilizers, reduce efficacy, and affect crop growth.

[0016] Preferably, the connecting pipe, the short pipe and one side of the pipeline therebetween are all provided with flow meters.

[0017] Working principle: First, send the detection device to the field to detect the soil in the field. After a period of time, observe the display screen of the spectrometer to observe the nutrients lacking in the soil for crops. Secondly, place the water pipe in the canal or river, and then start the water pump to transport water to the water tank through the pipe for storage. Then, discharge the water into multiple fertilizer storage tanks through the feed pipe. Since fertilizer is prone to precipitation or crystallization when stored for a long time, the motor 1 in the stirring mechanism can be started at this time to drive the stirring blade 1 on the rotating shaft 1 to stir the fertilizer to prevent precipitation or crystallization, so as to ensure that the fertilizer can flow out smoothly. After that, the ball valve is opened by the motor 3, and the liquid pump will extract the required fertilizer liquid and send it to the mixing tank. During this process, the flow meter will measure the flow rate of the fertilizer liquid. When a certain amount of fertilizer is sent to the mixing tank, the ball valve is closed. Valve, then, the water pump draws water from the water tank and sends it to the mixing tank. The water inlet of the mixing tank is located on the upper side of the outside of the mixing tank. The water flow will impact the fertilizer for preliminary mixing, and then the motor 2 drives the rotating shaft 2 to stir and mix the water and fertilizer. After the mixture is evenly mixed, the high-pressure pump draws the water-fertilizer mixture and supplies it to the liquid delivery pipe. If it is necessary to spray a certain field, open the corresponding ball valve, and the water-fertilizer mixture in the liquid delivery pipe will flow into the spray pipe. When the nozzle is blocked, the spray head can be replaced through the quick-release head. If the spray pipe is damaged, it can be replaced through the quick-release mechanism. Finally, the water-fertilizer mixture is sprayed out through the spray head and evenly applied to the field. However, when the operation is completed, the water pump is first used to irrigate the inside of the mixing tank for flushing, and then the motor 2 is started to drive the scraper on the rotating shaft 2 to scrape the inner wall of the tank body, and then the cleaning material inside the tank body is removed through the sewage outlet.

[0018] The present invention provides a fertilizer application device based on spectral detection, which has the following beneficial effects:

[0019] 1. The present invention uses a multi-layer filtration system of gravel, medium sand and fine sand through the filtration mechanism on the top of the water tank to remove impurities and harmful substances in the water, thereby effectively ensuring the cleanliness and purity of the water quality. Gravel is used as the first layer of filtration to mainly intercept larger suspended matter and particulate matter. Subsequently, the medium sand layer further refines the filtration to remove smaller impurities. Finally, the fine sand layer plays a role of deep purification to ensure that the water quality reaches the best state. In addition, the spectral characteristics of soil, etc. are detected by a spectrum detector, and its nutritional status and the type and amount of fertilizer required can be indirectly analyzed, which provides the possibility for precise fertilization. The metering component can also flexibly distribute and use water and fertilizer according to actual needs. For example, when a specific proportion of fertilizer is required, the equipment will also adjust the supply of fertilizer accordingly, thereby improving the overall operation efficiency of the equipment.

[0020] 2. The present invention can effectively prevent the precipitation or crystallization of fertilizer during storage through the stirring component in the fertilizer storage mechanism, ensuring that the quality of the fertilizer will not be affected by long-term storage, and also ensuring that the fertilizer can flow out smoothly. Through this stirring mechanism, the fertilizer particles can be kept evenly distributed during storage, avoiding the aggregation and stratification of particles caused by gravity. In addition, the function of the mixing mechanism is to fully stir and mix the water and fertilizer, ensuring that the fertilizer and water can be evenly combined, so that the fertilizer particles can be fully dissolved in the water, thereby forming a uniform water-fertilizer solution. After use, the scraper can be driven by motor 2 to thoroughly clean the interior of the tank body, keep the fertilizer storage tank clean, and avoid the tediousness and inconvenience of manual cleaning. At the same time, this also reduces the environmental pollution caused by residual fertilizer, making agricultural production more environmentally friendly and sustainable.

[0021] 3. The spray assembly of the present invention is tightly connected to the connecting pipe through a quick-disassembly mechanism. When the spray head is blocked or fails, the staff can replace the spray head through this quick-disassembly head. If the nozzle is damaged or needs repair, it can also be quickly replaced or repaired through this quick-disassembly mechanism, which greatly improves the convenience of equipment maintenance and replacement, reduces maintenance costs and required time, and significantly improves the practicality and durability of the equipment, making the operation of the entire system more efficient and reliable, bringing great convenience and economic benefits to users.
