Description

Technical Field

[0001] The invention relates to the technical field of pesticide spraying devices, and in particular to a pesticide spraying device for planting chrysanthemum with a multi-angle spraying function. Background Art

[0002] Pesticides refer to a substance or mixture of several substances and their preparations that are chemically synthesized or derived from biological or other natural substances and are used to prevent and control diseases, insects, weeds, rats and other harmful organisms that harm agriculture and forestry, and to purposefully regulate the growth of plants and insects. They are widely used in agricultural, forestry and animal husbandry production, environmental and household sanitation pest control and epidemic prevention, and industrial product mildew and moth prevention, etc.

[0003] A pesticide spraying device is a device that sprays water-soluble pesticides onto the surface of plants. Common spraying methods include spraying with backpack spray boxes, spraying with pesticide spraying vehicles, and spraying with drones.

[0004] Most of the existing large-scale pesticide spraying equipment sprays downward from the top, with a relatively fixed spraying angle, and the spraying distance is long and easily affected by the wind, resulting in uneven spraying. Pesticide spraying by drones will be affected by the wind of the drone rotors, making it impossible to fix the degree of diffusion of the medicine. Only manual labor with a medicine box and a handheld nozzle can spray at multiple angles and can spray in a targeted manner. However, in a Fubaichrysanthemum plantation, due to the dense Fubaichrysanthemum plants and lush branches and leaves, it is difficult for people to walk here, and manual spraying will inevitably stick to pesticides on the artificial legs. Being in this environment for a long time is harmful to health. When large-scale spraying equipment or drones are used to spray pesticides, it is difficult to spray the dense Fubaichrysanthemum plants comprehensively. Therefore, a pesticide spraying device for Fubaichrysanthemum planting with a multi-angle spraying function is proposed to solve the above-mentioned problems. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] In view of the shortcomings of the prior art, the present invention provides a pesticide spraying device for growing chrysanthemum with a multi-angle spraying function, which has the advantages of high safety and good spraying effect.

[0060] Working principle:

[0061] Step 1: Fix the slide rail 1 to the outside of the keel 7 of the existing greenhouse through the latch 8. Before use, first introduce the prepared pesticide into the medicine water pipe 903 through the water pump, and then introduce it into the water guide hole 403 through the medicine water pipe 903, and then introduce it into the sub-tube 405 through the inner tube 402, the outer tube 401, and the spray pipe 404 in sequence, and then the medicine is atomized and sprayed out through the spray head 406;

[0062] Step 2: When spraying pesticides, start the motor 205, the motor 205 drives the fourth gear 203 to rotate, and the gear transmission of the fourth gear 203 and the third gear 202 drives the worm 201 to rotate, so that the bottom plate 302 is driven to move through the gear transmission of the worm 201 and the transmission block 301.

At the same time, the two hanging wheels 304 generate a pulling force on the bottom plate 302 through the fixed plate 303, so that it will not fall due to the force due to the distance. During the translation process, it can cover the entire greenhouse from top to bottom to spray pesticides;

[0063] Step 3: During the translation process, the worm gear 504 is driven to rotate by the worm 201, thereby driving the second gear 502 to rotate through the transmission rod 503, and the outer tube 401 rotating outside the inner tube 402 is driven to rotate through the gear transmission of the second gear 502 and the first gear 501, so that the outer tube 401 drives the spray pipe 404 to revolve, and the water mist is sprayed from the spray head 406, and the thrust generated by the spray drives the sub-tube 405 to rotate, so that the sprayed pesticide can be sprayed in a rotating state, and the water droplets of the medicine can fall in a rotating state, wrapping around the plants, forming a better multi-angle spraying effect.
