[0002] Corn is an important cereal crop in my country, and its total output ranks second only to rice. During the corn planting process, it is very susceptible to diseases and pests, which can reduce the yield. For example, the main pest, the corn borer, will harm the corn stalks, leaves and ears. For this type of pest, pesticides are generally used to spray chlorantraniliprole suspension on the corn stalks and leaves for pest control. Common manual spraying is time-consuming and labor-intensive, and the pesticides will have health impacts on the spraying operators.

[0003] Chinese Patent Publication No. CN217742867U disclosed on November 8, 2022, a pesticide spraying device for corn disease and pest control. The patent can realize precise pesticide spraying on corn in a breeze environment through a second nozzle assembly, avoiding the breeze from blowing the pesticide to other crops; the problem with this technical solution is that, since the mature corn stalks are tall and thin, and the leaves are dense from bottom to top, relying on simple spraying of pesticides from top to bottom, the pesticide cannot be effectively sprayed on the lower leaves, which reduces the insecticide control effect of the lower leaves of the corn stalks; therefore, a pesticide spraying equipment is needed that can spray the pesticide to all heights of the corn stalks.

[0031] See also Figure 1-4 The utility model is a corn planting pesticide sprayer, comprising a medicine water tank 100, a spraying assembly 200 and an unmanned device 300. The spraying assembly 200 comprises a water pump 201, a connecting hose 202, a delivery pipe 203, a top spray pipe 204 and a side spray pipe 205. The medicine is delivered into the delivery pipe 203 by the water pump 201, and then sprayed onto the corn stalks through the top spray pipe 204 and the side spray pipe 205.

[0032] Specifically, the input end of the water pump 201 is connected to the medicine tank 100 through the connecting hose 202, and the output end of the water pump 201 is connected to the delivery pipe 203 through the connecting hose 202. The top spray pipe 204 is symmetrically arranged on both sides of the delivery pipe 203, and the side spray pipe 205 is arranged below the top spray pipe 204.

[0033] Furthermore, the number of the side nozzles 205 on each side of the delivery pipe 203 is 10.

[0034] Furthermore, a downward-facing top nozzle 204a is provided at the end of the top nozzle pipe 204, and an adjustable side nozzle 205a facing sideways is provided at the end of the side nozzle pipe 205.

[0035] Furthermore, a wind shield 204b is provided above the top nozzle 204a at one end of the top spray pipe 204.

[0036] Furthermore, a medicine box rack 101 is provided below the drone 300 , and the medicine box 100 is placed in the medicine box rack 101 .

[0037] Furthermore, a water pump bracket 201 a is provided below the drone 300 , and the water pump 201 is arranged on the test pump bracket 201 a .

[0038] The operation process of this embodiment is as follows: start the drone 300, remotely control the drone 300 so that the delivery pipe 203 is within the row interval of the corn field, the water pump 201 extracts the pesticide from the medicine tank 101 and delivers it to the delivery pipe 201, the delivery pipe 101 delivers the pesticide to each top spray pipe 204 and the side spray pipe 205, and then sprays it through each top nozzle 204a and the adjustable side nozzle 205a, the remotely controlled drone 300 travels along the row interval, and the adjustable side nozzle 205a sprays the pesticide on the stems and leaves at various heights. According to the height of the corn stalks and the demand for the amount of pesticide at different heights, the adjustable side nozzle 205a is adjusted to fully spray the pesticide at the required height position, and the wind shield 204b is used to prevent the wind force of the drone 300 blades from blowing the pesticide away.

[0039] Example 2

[0040] See also Figure 5-6 On the basis of Example 1, a sleeve 203a with a connecting axon 203b is sleeved on the delivery tube 203, and the connecting axon 203a is fixedly connected to the output end of the stepper motor 301 set on the drone 300.
