Description

Technical Field

[0001] This utility model relates to the technical field of equipment for vegetable planting, and in particular to a spraying device for vegetable planting. Background Technology

[0002] Vegetables are susceptible to pathogens such as fungi, bacteria, and viruses during their growth, leading to diseases such as downy mildew, powdery mildew, and anthracnose. These diseases can damage leaves, stems, or fruits, interfering with photosynthesis and nutrient transport, resulting in reduced yields or even crop failure. Using pesticides (such as fungicides) is an effective way to control pathogens and reduce diseases.

[0003] Currently used pesticide spraying equipment typically requires operators to carry the pesticide tank on their backs and hold the sprayer to spray vegetables. However, the spraying range of this equipment is limited, requiring workers to frequently move the sprayer up, down, left, and right to ensure that the pesticide evenly covers the crop surface. This not only increases the labor intensity of the workers' arms but also makes it difficult to guarantee the comprehensiveness and uniformity of pesticide coverage.

[0004] Therefore, it is necessary to propose a pesticide spraying device for vegetable cultivation, which aims to improve spraying efficiency and coverage while reducing the difficulty and physical exertion of manual operation. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a spraying device for vegetable planting.

[0006] The technical implementation scheme of this utility model is as follows: A spraying device for vegetable planting includes a base, casters, a push rod, a pesticide storage bin, a spray pump, a mounting frame, a support base, a rotating shell, spray pipes, a dual-shaft motor, and bevel gears. A caster is provided around the bottom of the base. A push rod for gripping and operation is provided on the rear top of the base. A pesticide storage bin for storing pesticides is also provided on the top of the base, along with a spray pump whose inlet is connected to the storage bin. A mounting frame is provided on the base in front of the storage bin. A support base is rotatably mounted between the two sides of the mounting frame. A rotating shell is rotatably mounted at each end of the support base. Spray pipes are symmetrically connected to the outlet of the spray pump. The two spray pipes extend through into the rotating shells on the same side. A dual-shaft motor is mounted on the support base. Bevel gears are provided on both output ends of the dual-shaft motor and on both rotating shells. Two adjacent bevel gears on the same side mesh with each other.

[0007] More preferably, it also includes mounting plates, clamps, and elastic elements. Mounting plates are provided on both inner sides of the mounting frame, and clamps that engage with the support base are inserted between the mounting plates on both sides. Elastic elements are provided between the clamps and the mounting plates on both sides.

[0008] More preferably, it also includes a mounting cover, a servo motor, and a stirring blade. The medicine storage chamber is equipped with a mounting cover, on which a fixedly mounted servo motor and a rotatably connected stirring blade are mounted. The output end of the servo motor is connected to the shaft end of the stirring blade.

[0009] More preferably, it also includes a limit bolt, with a limit bolt threaded through the perimeter of the mounting cover between the cover and the storage compartment.

[0010] More preferably, it also includes a rubber sleeve, which is provided at the grip of the push rod.

[0011] More preferably, it also includes a sealing ring, with a sealing ring on the mounting cover that fits against the inner wall of the medicine storage compartment opening.

[0012] Compared with the prior art, the present invention has the following advantages: 1.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: A pesticide spraying device for vegetable cultivation, such as... Figures 1-3 As shown, the device includes a base 1, casters 2, a push rod 3, a pesticide storage bin 4, a spray pump 5, a mounting frame 6, a support base 7, a rotating housing 8, a spray pipe 9, a dual-shaft motor 10, and a bevel gear 11. A caster 2 is installed around the bottom of the base 1, making the device more stable and smooth when moving in the field, especially suitable for large-scale vegetable planting areas, thus improving work efficiency. A push rod 3 is located on the top rear side of the base 1 for gripping and operation, facilitating control of the device's forward direction and speed. A pesticide storage bin 4 is also installed on the top of the base 1, and a spray pump with an inlet connected to the pesticide storage bin 4. 5. To achieve the extraction and delivery of the pesticide solution, a mounting frame 6 is fixedly installed on the base 1 in front of the pesticide storage chamber 4. A support base 7 is rotatably installed between the left and right sides of the mounting frame 6. A rotating shell 8 is rotatably installed at the left and right ends of the support base 7. Spraying pipes 9 are symmetrically connected to the outlet of the spray pump 5. The two spraying pipes 9 extend into the rotating shell 8 on the same side to spray the pesticide solution evenly onto the crop surface. A dual-shaft motor 10 is installed on the support base 7. Bevel gears 11 are installed on the output ends of the dual-shaft motor 10 on both sides and on the rotating shells 8 on both sides. Two adjacent bevel gears 11 on the same side mesh with each other.

[0022] As can be seen, the spray pipe 9 is located inside the rotatable housing 8, and works with the dual-axis motor 10 to drive the bevel gear 11 to rotate the housing 8, enabling the spray pipe 9 to perform rotary spraying. This design, combined with the linear movement of the device, can complete large-area, continuous, and uniform pesticide spraying operations, effectively avoiding the dead zones and repeated spraying problems commonly found in traditional manual hand-held spraying methods.

[0023] Meanwhile, by controlling the forward and reverse rotation of the dual-axis motor 10, the spray pipe 9 can be driven to perform left and right swing spraying, flexibly adjusting the spraying angle and coverage direction, thereby better adapting to vegetable plants of different heights and densities, and improving the effectiveness and coverage of disease control.

[0024] The entire spraying process is automatically driven by a dual-axis motor 10. Operators only need to push the device forward along the predetermined path, without having to frequently wave the hand-held spray boom, which significantly reduces labor intensity and improves work efficiency and ease of operation.

[0025] like Figure 3 As shown, the device also includes a mounting plate 12, a locking rod 13, and an elastic element 14. Mounting plates 12 are provided on both inner sides of the mounting frame 6. A locking rod 13, which engages with the support base 7, is inserted between the two mounting plates 12. An elastic element 14 is provided between the locking rod 13 and the two mounting plates 12. In this embodiment, the elastic element 14 is a spring. When the device is not in operation or needs to be stored, the locking rod 13 is pushed down to compress the elastic element 14, releasing the restriction on the support base 7. This allows the support base 7 and its components to rotate around the axis and retract to the vicinity of the push rod 3, reducing the overall space occupied and facilitating transportation and storage. After the operation is completed, the locking rod 13 is released, and the elastic element 14 automatically resets, re-fixing the support base 7 in the initial working position, enabling quick switching between operation and storage states, improving ease of use and safety.

[0026] like Figure 4 As shown, it also includes a mounting cover 15, a servo motor 16, and a stirring blade 17. The storage chamber 4 is covered with a mounting cover 15, on which a fixedly mounted servo motor 16 and a rotatably connected stirring blade 17 are installed. The output end of the servo motor 16 is connected to the shaft end of the stirring blade 17. When it is necessary to mix multiple pesticides or adjust the concentration of the pesticide solution, the stirring blade 17 can be driven to rotate by starting the servo motor 16 to fully stir the pesticide solution in the storage chamber 4, ensuring that the pesticide solution is evenly mixed and avoiding the spraying effect due to the stratification or sedimentation of the pesticide solution, thereby improving the scientificity and effectiveness of plant protection operations.

[0027] like Figure 4 As shown, it also includes a limit bolt 18, which is threaded between the mounting cover 15 and the medicine storage chamber 4 to fix the position of the mounting cover 15 and prevent it from loosening and falling off due to vibration during movement, thus ensuring the sealing and safety of the medicine storage chamber 4.

[0028] like Figure 2 As shown, it also includes a rubber sleeve 19. The rubber sleeve 19 is provided at the grip of the push rod 3. The rubber sleeve 19 improves the grip comfort of the operator's hand, enhances the anti-slip performance, reduces hand fatigue during long-term operation, and also has a certain shock absorption and cushioning effect, improving the stability of operation.

[0029] like Figure 4 As shown, it also includes a sealing ring 20. A sealing ring 20 is provided on the mounting cover 15 to fit the inner wall of the opening of the medicine storage chamber 4, so as to form a good sealing structure, prevent leakage of medicine during transportation or spraying, and ensure operational safety and environmental cleanliness.

[0030] When using the device, first loosen the limiting bolt 18 and open the mounting cover 15. As the mounting cover 15 opens, the servo motor 16 and stirring blade 17 fixed on it will move upward and be removed. Then, add the required pesticide to the storage chamber 4, and other agents can be added as needed, mixing until the required amount is reached. After filling, reset and tighten the mounting cover 15, start the servo motor 16 to drive the stirring blade 17 to rotate, and fully mix the pesticide solution in the storage chamber 4. Next, hold the push rod 3 and push the entire device to the area where spraying is needed. With the help of the moving wheels 2, the device moves more flexibly and conveniently. According to the working path, continuously push the device along the predetermined route. During this process, the dual-axis motor 10 is started synchronously, and its two output ends drive the bevel gears 11 to rotate. The two adjacent bevel gears 11 mesh as they rotate, thereby driving the adjacent bevel gears 11 to rotate, thus driving the rotating shell 8 and the spraying pipe 9 inside to rotate. Simultaneously, the spray pump 5 draws pesticide solution from the storage chamber 4 and delivers it to the spray pipe 9. Through rotational spraying, in conjunction with the movement of the device, it achieves uniform spraying of the vegetables. By controlling the forward and reverse rotation of the dual-axis motor 10, the spray pipe 9 achieves oscillating spraying, further improving the uniformity and coverage of the spray, thus achieving automated and efficient spraying operations. After use, the lever 13 is slid downwards along the mounting plate 12, causing the elastic element 14 to deform and release the restriction on the support base 7 and its components. The support base 7 is then tilted and rotated to fit against the push rod 3 for easy overall storage. After releasing the lever 13, the elastic element 14 automatically resets, re-fixing the support base 7 in the adjusted position, completing the entire operation process. This device, through optimized mechanical structure and automated control, significantly improves spraying efficiency and coverage, reduces manual labor intensity, and achieves efficient, uniform, and convenient plant protection operations.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
