[0002] In agricultural planting, it is often necessary to spray pesticides on crops to effectively prevent and control pests and diseases and increase crop nutrition. However, at present, the spraying process is still often carried out manually, which is not only time-consuming and labor-intensive, but also causes harm to the operator's health. Although there are corresponding spraying devices, the pesticide in the tank is prone to sedimentation during the spraying process, thereby reducing the efficacy of the pesticide.

[0003] Existing agricultural and forestry spraying equipment requires cleaning after use to avoid pesticide residue. The mixing tank is cleaned by stirring with a stirring rod, but it is difficult to completely remove the pesticide residue adhering to the inner wall of the mixing tank. This results in some pesticide residue remaining on the inner wall of the mixing tank, reducing the accuracy of the pesticide ratio for the next application and affecting the efficacy. Therefore, an agricultural and forestry plant protection spraying machine is proposed to solve the above problems. Utility Model Content

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.

[0030] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a plant protection sprayer for agricultural and forestry planting, including a base plate 1, which serves as the foundation of the entire machine and supports all components. A caster wheel 2 is fixedly connected to the bottom of the base plate 1, providing flexible mobility and facilitating movement of the equipment in fields or woodlands. A handrail 3 is fixedly connected to the top of the base plate 1, providing a gripping point for the operator and assisting in equipment steering and stability control. A mixing tank 4 is fixedly connected to the top of the base plate 1, storing pesticide solution and serving as a mixing container. An electric cylinder 109 is fixedly connected to the top to drive a mixing mechanism 10. A liquid outlet pipe 16 is fixedly connected to the front of the mixing tank 4, and the mixing mechanism 10 is installed inside the mixing tank 4.

[0031] Reference Figures 2-4The mixing mechanism 10 includes a vertical rod 101, a limiting rod 105, and a connecting rod 107. The vertical rod 101 is slidably connected to the inner wall of the mixing tank 4. A spiral groove 102 is provided on the middle surface of the vertical rod 101. A sleeve 103 is slidably connected to the surface of the spiral groove 102. An electric cylinder 109 drives the vertical rod 101 to move up and down. The spiral groove 102 cooperates with the sleeve 103 to convert the vertical motion into the rotational motion of the sleeve 103. The central axis of the sleeve 103 and the central axis of the vertical rod 101 are on the same straight line.

[0032] Reference Figures 2-4 A mixing blade 104 is fixedly connected to the circumferential surface of the sleeve 103. The blade rotates with the sleeve 103 to stir the liquid medicine, ensuring uniform mixing of the medicine. A limiting rod 105 is fixedly installed on the inner wall of the mixing tank 4. The end of the limiting rod 105 away from the inner wall of the mixing tank 4 is provided with an arc-shaped dome surface. The number of limiting rods 105 is set to multiple, and the multiple limiting rods 105 are arranged in a ring at equal angles on the inner wall of the mixing tank 4. A groove 106 is opened on the circumferential surface of the sleeve 103. The arc-shaped dome surface of the limiting rod 105 fits against the inner wall of the groove 106. The end of the limiting rod 105 away from the inner wall of the mixing tank 4 is slidably connected to the inner wall of the groove 106. The arc-shaped dome surface of the limiting rod 105 slides against the groove 106 of the sleeve 103, limiting the radial displacement of the sleeve 103 and ensuring rotational stability.

[0033] Reference Figure 3 and Figure 4 The connecting rod 107 is fixedly installed on the circumferential surface of the vertical rod 101. A scraper ring 108 is fixedly connected to the end of the connecting rod 107 away from the vertical rod 101. The scraper ring 108 is in contact with the inner wall of the mixing tank 4 to scrape off the residual liquid on the tank wall, preventing sedimentation and waste. The outer wall of the scraper ring 108 is in contact with the inner wall of the mixing tank 4. An electric cylinder 109 is fixedly connected to the top of the mixing tank 4. The bottom of the output shaft of the electric cylinder 109 is fixedly connected to the top of the vertical rod 101. A spraying mechanism 11 is provided on the top of the base plate 1.

[0034] Reference Figure 1 and Figure 2 The spraying mechanism 11 includes a water pump 111, which pumps the liquid medicine in the mixing tank 4 to the nozzle 114. The water pump 111 is fixedly installed on the top of the base plate 1 and is connected to the mixing tank 4 through the delivery pipe 115.

[0035] Reference Figure 1 and Figure 2The spraying mechanism 11 also includes a vertically arranged column 112, which is threaded onto the top of the water pump 111. A crossbar 113 is fixedly connected to the front and rear sides of the column 112. A nozzle 114 is threaded to the end of the crossbar 113 away from the column 112. The column 112 is threaded to the crossbar 113, and nozzles 114 are installed at both ends of the crossbar 113. The internal connection forms a spraying channel, and the position of the nozzle 114 can be adjusted according to the crop height. The interior of the column 112 is connected to the interior of the crossbar 113, and the interior of the crossbar 113 is connected to the interior of the nozzle 114.

[0036] Working principle: In use, first add the medicine and water to the mixing tank 4 in proportion. Start the electric cylinder 109, and its output shaft drives the vertical rod 101 to move up and down reciprocally. The spiral groove 102 on the surface of the vertical rod 101 slides in contact with the sleeve 103, converting the vertical motion into the rotational motion of the sleeve 103. The sleeve 103 drives the mixing blade 104 to rotate, which fully stirs the medicine in the mixing tank 4. At the same time, the arc-shaped dome surface of the limiting rod 105 is always in contact with the groove 106 of the sleeve 103, limiting its radial displacement and ensuring smooth rotation. The scraper ring 108 is in close contact with the inner wall of the mixing tank 4 during the up and down displacement, removing the attached medicine residue and preventing clumping or sedimentation.

[0037] Once the pesticide solution is evenly mixed, the water pump 111 is started, and the pesticide solution is pumped from the bottom of the mixing tank 4 to the spraying mechanism 11 through the delivery pipe 115. The pesticide solution flows into the crossbar 113 through the internal channel of the column 112, and is finally evenly sprayed onto the target area through the nozzle 114. The operator can adjust the length of the crossbar 113 and the coverage of the nozzle 114 to adapt to the needs of different crops or terrains. The combination of the dynamic stirring of the mixing mechanism 10 and the cleaning function of the scraper ring 108 ensures that the pesticide solution is evenly mixed and without residue, thus improving the efficiency and adaptability of the operation.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
