Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, specifically to a spraying equipment for field crops. Background Technology

[0002] In modern agricultural production systems, the scientific application of pesticides plays an irreplaceable role as a crucial link in the integrated pest management of crops. Understanding the patterns of pest and disease occurrence, rationally selecting pesticide types and application timing, and constructing a comprehensive control system have become important measures to ensure agricultural production safety and achieve stable and increased yields. Pesticide spraying is characterized by its clear mechanism of action, rapid onset of action, and stable control effects. In the early stages of pest and disease outbreaks, timely application of appropriate pesticides can effectively control the spread of diseases and / or pests, preventing the escalation of disasters.

[0003] Field crops are characterized by large planting areas, uniform crop varieties, and ease of centralized management. They are also easier to control through centralized pesticide application when pests and diseases occur. Therefore, field crop cultivation facilitates centralized management, reducing planting costs and increasing planting efficiency. Spraying of pesticides for field crops typically utilizes automated spraying facilities for centralized and efficient application.

[0004] However, most existing field crop spraying equipment has a fixed spraying angle, resulting in low uniformity of pesticide application. This makes it difficult for crops to be fully treated, such as only the top or one side being sprayed, leading to poor application results and unnecessary pesticide waste. In addition, spraying equipment is used frequently, and the types of pesticides used each time are often different. The equipment needs to be cleaned before each application, and cleaning the pipelines, nozzles, and other facilities is quite troublesome, which affects the application efficiency to some extent. Utility Model Content

[0005] In view of the shortcomings of existing technology, this utility model provides a new type of field crop spraying equipment that helps to improve the spraying range and facilitates pipeline cleaning.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0007] A field crop spraying device includes: a pesticide tank, with symmetrically liftable pipe assemblies connected to the top of the tank; the pipe assemblies include a spray frame guide tube; a nozzle guide tube is fixedly connected to the side of the spray frame guide tube that is away from each other; a turbine is rotatably connected inside the nozzle guide tube; a gear one is connected to the end of the turbine; a fixed plate is rotatably connected to the side of the gear one that is away from the nozzle guide tube; a slider is meshed with the gear one; the slider is slidably connected to the fixed plate; a gear two is meshed with the side of the slider that is away from the fixed plate; a swing plate is fixedly connected to the gear two; a nozzle is provided on the side of the swing plate that is away from the gear two; the nozzle is connected to the nozzle guide tube through a nozzle pipe.

[0008] When the spraying equipment is working, the pesticide passes through the nozzle guide tube via the pipeline assembly, which drives the turbine to rotate. The first gear follows the rotation of the turbine, causing the slider it meshes with to slide horizontally back and forth, thereby causing the second gear to rotate back and forth, and finally causing the nozzle to swing.

[0009] Preferably, the gear has teeth on less than half of its length, and the nozzle tube is a flexible tube with a length slightly longer than the distance between the nozzle guide tube and the nozzle.

[0010] The above plan further includes:

[0011] The pipeline assembly includes: a spray frame guide tube, which is connected to the medicine tank via a spray frame inlet pipe and a support leg. The end of the spray frame inlet pipe has an inlet hole, and the end of the spray frame guide tube has an outlet hole, which is connected to the nozzle guide tube.

[0012] The dispensing hole is the same size as the nozzle guide tube.

[0013] The medicine tank has horizontally arranged layered panels and vertically arranged partition plates inside. A sliding groove is provided in the medicine tank at the corresponding position of the spray frame's inlet pipe. The sliding groove has slots at both the upper and lower parts of the layered panels. Preferably, the slots are located at the bottom of the upper space and the lower space of the layered panels. The bottom end of the spray frame's inlet pipe is closed, with an inlet hole at the upper part of the bottom end that communicates with the corresponding slot. A lifting groove is provided in the medicine tank at the corresponding position of the support leg. A motor is fixedly installed at the bottom end of the lifting groove, and a threaded rod is provided at the motor's output end. A threaded hole is provided at the lower part of the support leg, and the threaded rod is threadedly connected to the support leg through the threaded hole.

[0014] The groove and the inlet hole are the same size. The upper layer of the medicine tank is a medicine layer, and the lower layer is a water layer. The chute penetrates the upper layer of the medicine tank. The inlet pipe of the spray frame is equipped with multiple flexible sealing rings or other sealing mechanisms to maintain a tight seal during sliding in the chute.

[0015] A rotating shaft is fixedly connected to the bottom of the medicine box, and a base is rotatably connected to the side of the rotating shaft away from the medicine box. Wheels are rotatably connected to the bottom of the base via a wheel plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. In the field crop spraying equipment of this application, the liquid pesticide flows within the pipe, driving the internal turbine to rotate and powering the spraying components. This causes the nozzle to oscillate periodically, significantly increasing the spraying range and optimizing the uniformity of spraying. This innovative design not only ensures uniform coverage of the pesticide solution and effectively improves the uniformity of crop treatment, but also significantly reduces pesticide waste. By optimizing pesticide utilization and expanding the spraying coverage, it greatly improves the efficiency and effectiveness of spraying operations.

[0018] 2. The field crop spraying equipment of this utility model has a medicine tank with two layers: the upper layer is the pesticide layer and the lower layer is the water layer. After the equipment has finished operating, the position of the spray frame is adjusted by controlling the motor so that the inlet enters the lower layer of the medicine tank. Then, the water in the lower layer of the medicine tank is used to automatically flush and clean the pipes and nozzles to prevent residual pesticides from affecting the next use.

[0019] 3. The bottom of the equipment has a rotatable structure, which can be rotated to adjust the horizontal position of the nozzle, making the equipment more flexible and adaptable during operation. Attached Figure Description

[0032] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Example 1

[0034] like Figures 1-11 As shown, a field crop spraying device includes: a pesticide tank 1, with a pipe assembly symmetrically and liftably connected to the top of the pesticide tank 1. The pipe assembly includes a spray frame guide tube 3, a nozzle guide tube 6 fixedly connected to the side of the spray frame guide tube 3 away from the nozzle, a turbine 17 rotatably connected inside the nozzle guide tube 6, a gear 16 fixedly connected to the side of the turbine 17 away from the nozzle guide tube 6, a fixed plate 12 rotatably connected to the side of the gear 16 away from the nozzle guide tube 6, a slider 11 meshing with the gear 16, the slider 11 slidably connected to the fixed plate 12, a gear 2 10 meshing with the side of the slider 11 away from the fixed plate 12, a gear 2 10 rotatably connected to one end of the fixed plate 12, a swing plate 9 fixedly connected to the gear 2 10, and a nozzle 8 connected to the side of the swing plate 9 away from the gear 2 10 via a nozzle pipe 7.

[0035] When the spraying equipment is working, the pesticide passes through the nozzle guide 6 via the pipeline assembly, which drives the turbine 17 to rotate, causing the gear 16 to rotate and drive the slider 11 connected to it to slide horizontally back and forth, thereby causing the gear 10 to rotate back and forth, and finally causing the nozzle 8 to swing.

[0036] The field crop spraying equipment proposed in this utility model is applied to field operations. Therefore, this application is a large-scale operating device. Its working principle is as follows: When the pesticide passes through the nozzle guide 6, the movement of the pesticide liquid will cause the turbine 17 to rotate. When the turbine 17 rotates, it drives the gear 16 to rotate. When the gear 16 is at the left end of the slider 11, the teeth of the gear 16 are on the right side, which in turn engages with the bottom teeth of the slider 11, causing the slider 11 to slide to the left until the gear 16 is on the right side of the slider 11. At this time, the teeth of the gear 16 are on the left side, which in turn engages with the top teeth of the slider 11, causing the slider 11 to slide to the right until the gear 16 is on the left side of the slider 11. This process is repeated, causing the slider 11 to slide horizontally and periodically. While the slider 11 is sliding periodically, the gear 10 below it is rotated periodically through the meshing of its teeth. The nozzle 8 will then swing with the movement of the gear 10, thereby making the spraying operation more uniform and efficient, and ensuring that the crops are treated more comprehensively and evenly.

[0037] Example 2

[0038] like Figures 1-11 As shown, the pipeline assembly includes: a spray frame guide tube 3, a spray frame inlet pipe 26 and a support leg 2 on the side of the spray frame guide tube 3 near the medicine tank 1, a symmetrical inlet hole 13 is opened at the end of the spray frame inlet pipe 26 away from the spray frame guide tube 3, a threaded hole 14 is opened at the end of the support leg 2 away from the spray frame guide tube 3, and a discharge hole 15 is opened at the end of the spray frame guide tube 3 and connected to the nozzle guide tube 6 through the discharge hole 15.

[0039] The medicine tank 1 has a horizontally arranged layered plate 27 inside, dividing it into an upper and lower layer. A vertically arranged partition plate 22 is located at the center of the inside of the medicine tank 1. The medicine tank 1 is preferably a detachable structure, and both the upper and lower layers can selectively have sealable liquid filling pipe holes and air vents. A sliding groove 19 is provided at the corresponding position of the medicine inlet pipe 26 of the spray frame in the medicine tank 1, and the sliding groove 19 has symmetrically arranged slot holes 21. A lifting groove 20 is provided at the corresponding position of the support leg 2 of the medicine tank 1. A motor 23 is fixedly connected to the end of the lifting groove 20 away from the spray frame guide tube 3, and a threaded rod 18 is provided at the output end of the motor 23. A rotating shaft 24 is fixedly connected to the side of the medicine tank 1 away from the spray frame guide tube 3, and a base 4 is rotatably connected to the side of the rotating shaft 24 away from the medicine tank 1.

[0040] A wheel plate 25 is rotatably connected to the side of the base 4 away from the rotating shaft 24, and a wheel 5 with a locking device is rotatably connected to the end of the wheel plate 25 away from the base 4.

[0041] The working principle of the field crop spraying equipment proposed in this utility model is as follows: Since the threaded rod 18 is threadedly connected to the support leg 2 through the threaded hole 14, and the support leg 2 is slidably connected to the lifting groove 20, when the threaded rod 18 rotates, the support leg 2 rises, ultimately raising the spraying frame. When the equipment starts working, the motor 23 rotates, controlling the threaded rod 18 to rotate and raise the spraying frame until the inlet hole 13 corresponds to the groove hole 21. Then, the motor 23 stops rotating, and the equipment begins to extract pesticide from the upper layer of the pesticide tank 1 for spraying. After the equipment finishes operating, the motor 23 rotates in the opposite direction, controlling the threaded rod 18 to rotate in the opposite direction, causing the support leg 2 to lower the spraying frame until the inlet hole 13 reaches the lower end of the sliding groove 19. Then, the motor 23 stops rotating, and the equipment begins to extract clean water from the lower layer of the pesticide tank 1 to self-clean the pipes and nozzles, eliminating the impact of residual pesticides on the next spraying operation.

[0042] The above are merely preferred embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of the present utility model, should be covered within the protection scope of the present utility model.
