Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of atomization devices, in particular to a spraying device for killing pests of durian seedlings. BACKGROUND

[0002] Durian seedlings are extremely susceptible to various pests such as scale insects, aphids, red spiders and beetles during their critical growth stages. These pests not only interfere with the normal growth of the seedlings, but in severe cases can even cause leaf damage, growth stagnation, and even whole plant death, posing a significant threat to the early investment and development of the durian industry. Current pest control methods, such as the use of physical pest control methods (such as insect traps and traps), have limited effectiveness against specific pests or specific growth stages, and the pest control effect is not good, making it difficult to fully control mixed pests. The mainstream back-mounted or handheld spraying operation is extremely susceptible to wind interference. In the common open planting environment, the spraying operation is easily affected by windy weather, and the wind disturbance causes severe drift of the mist droplets, which on the one hand significantly reduces the effective deposition rate and coverage rate of the pesticide on the target site of the seedlings, affecting the insecticidal effect; on the other hand, the drifting pesticide causes environmental pollution and waste. When manually spraying in close proximity and a small area, especially in windy conditions, the operator is at high risk of inhaling or skin contact with pesticides, posing a direct threat to health and leading to poor safety during the spraying operation. Therefore, there is an urgent need to develop a new type of spraying device that can overcome wind disturbance, achieve precise and efficient pesticide application, ensure operator safety, and effectively address the pest control needs of durian seedlings.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0016] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0017] Example 1 like Figure 1 As shown, a spraying device for pest control in durian seedlings includes a folding mechanism 1 rotatably mounted on a support and a swinging spraying mechanism 3 mounted on the folding mechanism 1. Figure 2 As shown, the folding mechanism 1 includes an annular track 11, in which several sliding members 12 are arranged. Adjacent sliding members 12 are connected by two hinged folding links 13. The several sliding members 12 are connected in sequence. The first sliding member 12 is fixed on the annular track 11, and the top of the last sliding member 12 is hinged to a drive link 14. The drive link 14 is connected to a folding drive motor 15 on the annular track 11. By rotating the folding drive motor 15 in both directions, the drive link 14 is rotated, so that except for the fixed sliding member 12, the other sliding members 12 move along the annular track 11, realizing the folding and unfolding action.

[0018] A sealing mesh 2 is provided on the outside of the folding mechanism 1. Figure 2To demonstrate the internal structure of the sealing net 2, only half of it is shown. A lower fixing rod 17 is located at the bottom of the sliding member 12, and an upper fixing rod 19 is located at the top. The sealing net 2 is fixed to the lower fixing rod 17 and the upper fixing rod 19, allowing it to move with the sliding member 12. A gravity block 21 is located at the bottom of the sealing net 2, ensuring a relative seal between the sealing net 2 and the ground, and also allowing the sealing net 2 to better follow the movement of the sliding member 12. Note that magnetic adsorption components or a certain overlap are provided at the fixed end and tail end of the sealing net 2 to ensure a relatively sealed sealing space. A mounting bracket 18 is provided inside the annular guide rail, and the top of the sealing net 2 is fixed to the circumference of the rotating bearing 111. Folding and unfolding are achieved for the sealing net 2.

[0019] The folding mechanism 1 is equipped with several swing spray mechanisms 3. Two folding connecting rods 13 are hinged together by a hinge shaft 110. The swing spray mechanism 3 is mounted on the hinge shaft 110. The swing spray mechanism 3 includes a spray pipe 31 fixed on the hinge shaft 110. Several linearly distributed swing nozzles 32 (swinging up and down) are provided on the spray pipe 31. Adjacent spray pipes 31 are connected by a connecting pipe 5. One of the connecting pipes 5 is connected to the supply pipe 41 of the mobile liquid supply mechanism 4 through a connector 33. The mobile liquid supply mechanism 4 includes a supply pipe 41 and a liquid tank 42 connected to the supply pipe 41. The liquid tank 42 is mounted on a mobile trolley 43.

[0020] During pesticide spraying, the folding mechanism 1 unfolds the sealing net 2, covering the durian seedlings within the sealed space formed by the net 2. After the folding mechanism 1 is unfolded, several oscillating spraying mechanisms 3 are distributed circumferentially. The oscillating spraying mechanisms 3 are connected to a mobile liquid supply mechanism 4 via a connecting pipe 5. After the mobile liquid supply mechanism 4 is activated, the durian seedlings are treated with pesticides within the sealed net 2, unaffected by windy weather. Simultaneously, the pesticide is sprayed within the sealed space, preventing the pesticide from spreading to other locations, reducing pesticide usage, and ensuring the safety of the operator. The folding drive motor 15 is connected to the bracket via a rotating bearing 111. An operating lever 16 is provided at the tail of the folding drive motor 15. By operating the lever 16 to rotate the entire device, rotation within a certain angle range in the horizontal direction is achieved, enabling 360° spraying of pesticides onto the durian seedlings.

[0021] Example 2 The difference between this embodiment and Embodiment 1 is as follows: Figure 3As shown, a device for blowing insects has been added. The bottom of the spray pipe 31 is rotatably connected to the blower pipe 6 via a cross hinge. The blower pipe 6 has an air outlet. Adjacent blower pipes 6 are connected by a connecting pipe 5. One of the connecting pipes 5 is connected to an air pump 7. An insect suction pipe 8 is installed on the top mounting bracket. A filter box 9 is installed on the insect suction pipe 8. The insect suction pipe 8 is connected to the air inlet of the air pump 7. When physical blowing insects are needed, the blower pipes 6 are unfolded in sequence so that the air outlet of the blower pipe 6 is opposite to the bottom of the durian seedling. The air pump 7 is started, and the high-pressure airflow blows the durian seedling, causing the pests attached to the leaves or branches to be detached. The pests enter the filter box 9 through the insect suction pipe 8. The filter box 9 is equipped with a one-way valve to prevent the pests from flying out or crawling out again through the insect suction pipe 8. Physical pest control is carried out by blowing, which, combined with chemical pest control, improves the pest control effect.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
