[0002] During the process of fruit tree planting, the root system, as the basis for the growth of fruit trees, directly affects the growth potential, yield and fruit quality of fruit trees. However, since the root system of fruit trees is deeply buried in the soil, there are many challenges and limitations in directly applying fertilizers and pesticides to it.

[0003] However, the traditional method of fertilizing the root system of fruit trees is mostly to directly bury fertilizers after manually digging the soil. This method not only has a large labor intensity and low efficiency, but also has a low fertilizer utilization rate, which is easy to cause waste and soil pollution. For the prevention and control of diseases and pests of the root system of fruit trees, since the roots are located in the soil, it is difficult to directly observe and judge the occurrence of diseases and pests. Therefore, pesticides are mostly sprayed on the ground. However, the utilization rate of pesticides in this way is low, and it is easy to cause pesticide residues and environmental pollution. Content of the Utility Model

[0004] The utility model provides a device for preventing and controlling diseases, pests, fertilizing and applying pesticides to the roots of fruit trees, aiming to solve the problem that it is difficult to directly apply fertilizers and pesticides for pest control due to the roots of fruit trees being located in the soil in current fruit tree planting.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0021] An embodiment of the present utility model provides a device for preventing and controlling diseases, pests, fertilizing, and applying pesticides to the roots of fruit trees, as Figures 1-4 shown. The device for preventing and controlling diseases, pests, fertilizing, and applying pesticides to the roots of fruit trees includes: a box body 1, in which a liquid medicine chamber 2 and a fertilizer and water chamber 3 are provided. The liquid medicine chamber 2 is used for containing liquid medicine for preventing and controlling diseases and pests of fruit tree roots, and the fertilizer and water chamber 3 is used for containing fertilizer and water required for the growth of fruit trees; an installation box 4, which is fixedly installed at the bottom of the box body 1. Two liquid pumping pumps 5 are provided in the installation box 4, and the two liquid pumping pumps 5 are respectively used for pumping liquid medicine and fertilizer and water; two liquid spraying pipes 7, which are respectively fixedly installed at the liquid outlet ends of the two liquid pumping pumps 5; two installation frames 8, which are symmetrically and fixedly installed at the bottom of the installation box 4; an installation shell 9, which is fixedly installed on the installation frames 8. Two drill rods 10 for drilling soil and digging pits are provided on the installation shell 9; a driving mechanism for driving the two drill rods 10 to rotate, and the driving mechanism is arranged on the installation box 4 and the installation shell 9.

[0022] It should be noted that the deficiencies of the traditional fruit tree root fertilization method are as follows: High labor intensity: During the fruit tree planting process, for fertilization, farmers usually need to manually dig the soil and then bury the fertilizer. This operation method not only requires farmers to have a large amount of physical strength, but also requires long-term bending and digging, which is likely to cause physical fatigue and injury; Low efficiency: Since fertilization needs to be carried out for each fruit tree one by one, the processes of digging the soil and burying the fertilizer are quite time-consuming. In large-scale orchards, this inefficient fertilization method will greatly increase the operation time and reduce the overall production efficiency; Low fertilizer utilization rate: For fertilizers directly buried in the soil, due to the influence of various factors such as soil structure, humidity, and microbial activities, their dissolution and release speeds are often slow, resulting in a low fertilizer utilization rate. At the same time, fertilizers are easily fixed or lost in the soil, further reducing the fertilizer utilization rate; Prone to waste and soil pollution: Due to the low fertilizer utilization rate, farmers often use excessive amounts of fertilizers when fertilizing, which not only increases costs, but also easily causes soil eutrophication and even leads to water pollution; The deficiencies of the traditional fruit tree root pest and disease control methods are as follows: Difficult to directly observe and judge the occurrence of pests and diseases: The roots of fruit trees are located in the soil, and it is difficult to directly observe their growth status and health conditions. Therefore, farmers often have difficulty accurately judging the occurrence of pests and diseases, resulting in untimely prevention and control or over-prevention and control; Low pesticide utilization rate: For the traditional method of spraying pesticides on the ground, since pesticides are difficult to directly act on the roots and are affected by natural factors such as wind and rain, the pesticide utilization rate is often low. This not only increases the amount of pesticides used, but also raises the control cost; Prone to pesticide residues and environmental pollution: Due to the low pesticide utilization rate, a large amount of pesticides remain in the soil and the environment, posing a potential threat to the ecological environment. At the same time, pesticide residues may also enter the human body through the food chain, causing harm to human health; In summary, there are many deficiencies in the traditional fruit tree root fertilization and pest and disease control methods, and a new fruit tree root pest and disease control, fertilization, and pesticide application device needs to be developed to solve the above problems;

[0023] In this embodiment, the box body 1: As the main part of the entire device, a liquid medicine chamber 2 and a fertilizer-water chamber 3 are arranged inside.

Through the precise control of the driving mechanism, it can be ensured that the drill rod 10 works according to the predetermined trajectory and speed, so as to realize the precise fertilization and pesticide application to the fruit tree roots; Through automated and mechanized means, the labor intensity of farmers is greatly reduced and the work efficiency is improved; The precise fertilization and pesticide application methods can ensure that the liquid medicine and the fertilizer-water directly act on the fruit tree roots, improving the utilization rate and reducing waste; Due to the improvement of the utilization rate of the liquid medicine and the fertilizer-water, the possibility of overuse and loss is reduced.

[0025] In this embodiment, the design of the driving mechanism significantly improves the functionality and operating efficiency of the device for preventing and controlling pests and diseases, fertilizing, and applying pesticides to the root systems of fruit trees. Specifically, the driving mechanism includes the following key components: Three rotating shafts 11 are rotatably installed on the top of the installation shell 9, and they constitute the main transmission shafts of the entire driving mechanism. By rotating the rotating shafts, other components connected thereto can be driven to move; A pulley 12 is fixedly installed on each rotating shaft 11. These pulleys are used to transmit power through the timing belt 13 to ensure the coordinated operation of each component; The timing belt 13 is sleeved on the corresponding pulley 12, playing a key role in power transmission. The design of the timing belt ensures stable power transmission and avoids slipping or stalling during the transmission process; The motor 14 is fixed at the bottom of the installation box 4 and is the power source of the entire driving mechanism. The output shaft of the motor 14 is connected to the rotating shaft 11 through a coupling 15, converting electrical energy into mechanical energy to drive the rotating shaft 11 to rotate; The coupling 15 is fixedly installed at one end of the corresponding rotating shaft 11 respectively, with one end connected to the output shaft of the motor 14 and the other end fixedly connected to the top end of the drill rod 10. This connection method ensures that the power of the motor 14 can be directly transmitted to the drill rod 10 to drive the drill rod 10 to rotate, thereby achieving the purpose of drilling soil and digging pits; Through the coordinated operation of the motor 14, the coupling 15, the rotating shaft 11, the pulley 12, and the timing belt 13, stable power transmission from the motor to the drill rod is achieved, ensuring that the drill rod can rotate at a predetermined speed and direction; The entire driving mechanism adopts an electric drive method, and by simply controlling the switch and speed of the motor 14, precise control of the drill rod 10 can be achieved. Compared with the traditional manual excavation method, the labor intensity of the operator is greatly reduced; The driving mechanism is applicable to different soil types and fruit tree root systems of different sizes. By adjusting the speed of the motor 14 and the diameter of the drill rod 10, soil of different depths and widths can be excavated; Due to the adoption of electric drive and automatic control, the device can complete the fertilization and pesticide application work of a large number of fruit trees in a short time, greatly improving the work efficiency.

Through such a design, it is ensured that the liquid suction pump 5 can directly extract the required liquid from the corresponding chamber. More importantly, electromagnetic valves are also provided on the liquid suction pipes 6. An electromagnetic valve is a basic automation component controlled by electromagnetism to open and close. It is a basic automation component used to control fluids in an automation system and belongs to an actuator. The electromagnetic valve is used to control parameters such as the flow direction of the liquid, the flow rate of the liquid, the speed of the liquid, the time of the liquid, and the pressure of the liquid; by controlling the opening and closing of the electromagnetic valve, the extraction and stop of the liquid medicine and the fertilizer and water can be precisely controlled, so as to ensure that the fertilization and pesticide application processes can be carried out according to the predetermined amount, avoiding problems of overage or shortage; since the extraction amount of the liquid can be accurately controlled, the waste of the liquid medicine and the fertilizer and water can be minimized to the greatest extent, reducing the use cost.
