Description

Technical Field

[0001] This utility model relates to the field of spraying technology, and in particular to a drug spraying device for vegetable seedlings. Background Technology

[0002] Vegetable seedlings refer to vegetable seeds that have been carefully cultivated to germinate and grow to a certain stage, forming seedlings with roots, stems, and leaves. They are usually ready for transplanting or planting within 1-2 months after germination. The quality of vegetable seedlings directly affects the yield and quality of vegetables later on. Therefore, cultivating healthy and robust vegetable seedlings is of great significance in agricultural production. During the cultivation of vegetable seedlings, it is necessary to spray some pesticides to help the seedlings grow better.

[0003] Traditional vegetable seedling pesticide spraying devices mainly rely on manual operation, which not only consumes a lot of time and labor, but also makes it difficult to ensure the consistency and uniformity of spraying. Due to the lack of automated control, the spraying efficiency of these devices is generally low and cannot quickly cover a wide planting area. In addition, the spray head adjustment function of traditional spraying devices is limited, making it difficult to make appropriate adjustments for crops of different heights and shapes, resulting in unsatisfactory spraying effects.

[0004] Therefore, those skilled in the art have provided a pesticide spraying device for vegetable seedlings to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pesticide spraying device for vegetable seedlings. Through the coordinated operation of a first servo motor and a second servo motor, the spray head can be adjusted 90 degrees in both the horizontal and vertical directions, thus flexibly adapting to the height and shape of different crops. Automated control allows for rapid adjustment of spraying parameters, improving spraying efficiency and reducing manual operation. Simultaneously, the stirring rod and multiple stirring blades inside the device, driven by a third servo motor, ensure thorough mixing and uniformity of the pesticide solution in the tank, preventing pesticide sedimentation and further improving the uniformity of spraying and the degree of automation of the device.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A pesticide spraying device for vegetable seedlings includes a base, a spray head, and a pesticide tank. A mounting block is fixedly connected to the front end of the inner bottom surface of the base. A first servo motor is fixedly connected to the inner bottom surface of the upper middle part of the mounting block. The output end of the first servo motor passes through the mounting block to the upper end of the mounting block and is fixedly connected to a support rod. The lower end of the support rod is rotatably connected to the middle part of the upper surface of the mounting block. A fixed disc is fixedly connected to the upper end of the support rod. Mounting frames are fixedly connected to both sides of the middle part of the upper surface of the fixed disc. A first protective shell is fixedly connected to the middle part of one side of the outer wall of the upper end of one mounting frame. A second servo motor is disposed inside the first protective shell. The spray head is located in the middle of the mounting frame. Connecting rods are fixedly connected to both sides of the outer wall of the rear end of the spray head. The output end of one side of the second servo motor passes through the mounting frame and is fixedly connected to the middle part of one side of the connecting rod. The outer wall of the connecting rod away from the center of the spray head is rotatably connected to the inner wall of the middle part of the upper end of the mounting frame.

[0008] Through the above technical solution, the position and movement of the spray head can be controlled by the combined use of the first servo motor and the second servo motor, thereby adjusting the spraying range and spray volume. The first servo motor allows the spray head to be adjusted horizontally by 90 degrees forward, and the second servo motor allows the spray head to be adjusted vertically by 90 degrees forward. This design allows the spray head to be adjusted in multiple directions to adapt to crops of different heights and shapes. Through automated control, spraying parameters can be quickly adjusted, spraying efficiency can be improved, and the need for manual operation can be reduced.

[0009] Furthermore, the lower end of the medicine box is fixedly connected to the inner bottom surface of the rear end of the base, the upper surface of the medicine box is tightly fitted with a box lid, the middle of the upper surface of the box lid is fixedly connected to a second protective shell, a third servo motor is installed inside the second protective shell, a stirring rod is installed inside the medicine box, the upper end of the stirring rod is connected through to the middle of the box lid, the output end of the third servo motor passes through the second protective shell and is fixedly connected to the middle of the upper end of the stirring rod, and multiple stirring blades are fixedly connected to the outer wall of the lower end of the stirring rod, all of which are located inside the medicine box;

[0010] The above technical solution ensures that the medicine liquid is fully stirred inside the medicine tank by designing a stirring rod and multiple stirring blades, preventing drug sedimentation and ensuring the uniformity of the medicine liquid during spraying. The setting of the third servo motor realizes automatic stirring of the medicine liquid, reduces manual intervention and improves the degree of automation.

[0011] Furthermore, a support block is fixedly connected to the middle of the rear end of the upper surface of the mounting block, and a high-pressure pump is fixedly connected to the upper surface of the support block. The suction port of the high-pressure pump is connected to the lower end of the inside of the medicine tank through a pipe, and a hose is connected to the outlet of the high-pressure pump. The upper part of the front end of the hose is connected to the inside of the rear end of the spray head.

[0012] The above technical solution effectively prevents contamination of the pesticide solution during transportation by using pipes and hoses to transport the pesticide solution from the tank to the spray head. The high-pressure pump can deliver the pesticide solution to the spray head at a high pressure, thereby achieving efficient and uniform spraying, improving the efficiency of pesticide use and crop coverage. The use of hoses allows the spray head to move flexibly to adapt to crops at different heights and locations, increasing the range of applications of the device.

[0013] Furthermore, the upper end of the third servo motor is fixedly connected to the inner bottom surface of the second protective shell, and one side of the second servo motor is fixedly connected to the inner wall of one side of the first protective shell.

[0015] Furthermore, a sealing gasket is fixedly connected to the middle of the lower surface of the box lid, and the outer wall of the sealing gasket is tightly fitted to the inner wall of the upper end of the medicine box;

[0016] The above technical solution effectively prevents medicine leakage by using a sealing gasket, ensuring the integrity and concentration of the medicine inside the medicine box and avoiding waste and environmental pollution caused by medicine leakage.

[0017] Furthermore, a PLC control panel is fixedly connected to the middle of one side of the outer wall of the base;

[0018] The above technical solution uses a PLC control panel to control the operation of the entire spraying device.

[0019] Furthermore, brake casters are fixedly connected to the four corners of the lower surface of the base, and a battery plate is installed inside the lower end of the base;

[0020] The above technical solution utilizes braked casters for both moving and fixing the device, and a solar panel to provide power to the entire device.

[0021] Furthermore, a pusher is fixedly connected to the outer wall of the rear end of the base;

[0022] The above technical solution utilizes a hand-operated push-pull mechanism.

[0023] This utility model has the following beneficial effects:
