Description

TECHNICAL FIELD

[0001] The application belongs to the field of fertilizer irrigation, and particularly relates to a precise fertilizer application device. BACKGROUND

[0002] When fertilizing crops, factors such as plant characteristics, nutrient requirements and growth stages need to be considered comprehensively, and root fertilization and spray fertilization are selected for different crops according to specific crop and cultivation management requirements. For example, most vegetables and fruit trees mainly absorb nutrients through roots, and the roots of these crops are relatively developed, and nutrients are usually absorbed in the deep soil, so root fertilization is a more suitable method. However, the root absorption capacity of some crops is relatively weak, or they are not suitable for conventional fertilization methods, such as some leafy vegetables, which are more suitable for fertilization by leaf spray fertilization, so that the plant leaves directly absorb nutrients. Some nutrients are relatively easy to move and effectively absorbed in the soil, such as nitrogen and phosphorus, and root fertilization can meet the requirements. However, some nutrients move slowly in the soil, or crops are more sensitive to them, such as calcium and magnesium, and spray fertilization can better meet the requirements. At the same time, plants have different nutrient requirements at different growth stages. In the seedling stage, the root system of the plant is not fully developed, and spray fertilization can provide rapid nutrient supply, while in the mature stage, root fertilization can better meet the long-term nutrient requirements of crops. In summary, selecting the appropriate fertilization method can better meet the nutrient requirements of crops.

[0003] However, current fertilization devices can usually only meet one fertilization method, and cannot flexibly select the fertilization method according to the fertilization requirements. A precise fertilizer application device is needed, which is provided with two fertilization structures to select root fertilization and spray fertilization according to actual requirements.

[0020] like Figure 1 The precision fertilization device shown includes: a trolley 1 and a battery 3, a fertilizer tank 4, a motor 5, a fertilizer pump 9, a fertilizer applicator 15, a micro-spraying belt 13, an ultrasonic sensor 19, and a control box 18, all mounted on the trolley 1. The trolley 1 is equipped with multiple wheels 2, allowing it to move and apply fertilizer within the fertilization area, reducing the burden on workers. The battery 3, mounted on the trolley 1, is connected to the control box 18, providing power to the control box 18. The control box 18 is connected to the fertilizer pump 9, the motor 5, and the ultrasonic sensor 19.

[0021] The liquid tank 4 is provided with a stirring device and a liquid suction pipe 8. The stirring device comprises a motor 5 and a stirring rod 7. The output shaft of the motor 5 penetrates the liquid tank 4 and is connected with the stirring rod 7. A plurality of stirring shafts are arranged on the stirring rod 7. After the solid fertilizer and the liquid fertilizer are put into the liquid tank 4 through the opening of the feeding cover 6, the motor 5 is started. The motor 5 drives the stirring rod 7 and the stirring shafts to rotate in the liquid tank 4, so that the fertilizer is uniformly mixed. When the detection value of the ultrasonic sensor 19 is at a relatively stable value, the control box 18 judges that the liquid fertilizer is uniformly stirred, the frequency of the motor 5 is adjusted to be low, and the stirring rod 7 rotates at a uniform speed in the liquid tank 4. The liquid fertilizer is prevented from being precipitated to cause the inconsistency of the liquid fertilizer concentration and affect the fertilization effect.

[0022] The liquid suction pipe 8 is connected with the water inlet of the liquid fertilizer pump 9. The water outlet of the liquid fertilizer pump 9 is connected with a liquid outlet pipe 10. The liquid outlet pipe 10 is a three-way pipe. The left end of the liquid outlet pipe 10 is connected with the liquid fertilizer pump 9. The right end of the liquid outlet pipe 10 is connected with the micro-spraying belt 13 through a hose 14. The lower end of the liquid outlet pipe 10 is connected with the fertilizer applicator 15 through the hose 14. The right end of the liquid outlet pipe 10 is provided with a first valve 11. The lower end of the liquid outlet pipe 10 is provided with a second valve 12. The first valve 11 and the second valve 12 are electric valves. The first valve 11 and the second valve 12 are used to switch the fertilizer applicator 15 and the micro-spraying belt 13.

[0023] A pair of threaded holes are formed at the two ends of the tail of the cart 1. The distance between the threaded holes is determined based on the length of the required micro-spraying belt 13. A clamping rod 20 is inserted into each of the threaded holes. The micro-spraying belt 13 is installed at the end of the clamping rod 20. The spraying height of the micro-spraying belt 13 is adjusted by the clamping rod 20. The clamping rod 20 is an L-shaped rod, which comprises a vertical rod and a horizontal rod connected with the end of the vertical rod. The ends of the horizontal rod are connected with the two ends of the micro-spraying belt 13 through a clamp. The vertical rod is provided with a thread. The vertical rod is screwed with the cart 1. After the height of the micro-spraying belt 13 is adjusted to be at a proper position, the clamping rod 20 is locked with the cart 1 by a nut.

[0024] The first valve 11 and the second valve 12 are in a normally closed state. When the fertilizer needs to be sprayed, the liquid fertilizer pump 9 and the first valve 11 are opened. At this time, the liquid fertilizer is transported from the liquid fertilizer pump 9, the liquid outlet pipe 10 and the hose 14 to the micro-spraying belt 13. The micro-spraying belt 13 sprays the fertilizer on the upper part of the crops. When the root fertilization is needed, the liquid fertilizer pump 9 and the second valve 12 are opened. At this time, the liquid fertilizer is transported from the liquid fertilizer pump 9, the liquid outlet pipe 10 and the hose 14 to the fertilizer applicator 15. The fertilizer applicator 15 is a columnar structure. The feeding end is provided with a conical structure. When in use, the feeding end is inserted into the area to be fertilized. After the quantitative fertilizer is injected, the feeding end is pulled out. In order to facilitate the force, as shown in the figure, a thimble 16 is welded on the fertilizer applicator 15. The thimble 16 is connected with a handle 17 at both sides. The handle 17 is an n-shaped structure. When in use, the handle 17 is held at the top to insert the fertilizer applicator 15 into the soil.
