[0002] A plant protection agent refers to a fungicide applied before a plant pathogen invades the plant body, so that the plant is protected from the infection and harm of the pathogen. A fungicide with protective properties for plants is called a plant protection agent.

[0003] When spraying a plant protection agent, a spraying device for plant protection agents is required. The plant protection agent in the liquid storage tank is pumped out to the inside of the nozzle through an air pump, and then the nozzle sprays out the plant protection agent. However, the spraying angle of the nozzle of the existing plant protection agent spraying device is a fixed angle and cannot be adjusted. Moreover, due to the relatively large overall size of the plant protection agent spraying device, when there are obstacles in front of the plant protection agent spraying device, the distance between the nozzle and the plant to be sprayed is relatively far, which easily causes incomplete spraying. The spraying range of the nozzle of the existing structure for the plant protection agent is relatively limited. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , the present invention provides a technical solution for a plant protection agent spraying device: a plant protection agent spraying device, including a base 1 and a sprinkler head 6. A liquid storage tank 2 is installed on the top of the base 1, a water pump 3 is installed on the top of the liquid storage tank 2, and an adjusting mechanism 7 is installed on the top of the base 1. The adjusting mechanism 7 is used to adjust the spraying angle and axial position of the sprinkler head 6;

[0023] The adjusting mechanism 7 includes a first driving component and a second driving component;

[0024] The first driving component is used to adjust the axial moving position of the sprinkler head 6;

[0027] In this embodiment: By connecting the water pump 3 to power and running, the water pump 3 in the running state pumps out the plant protection agent in the liquid storage tank 2 through the output pipe 4, and the water pump 3 in the running state then inputs it into the sprinkler head 6 through the delivery pipe 5.

[0028] Please pay special attention to Figure 2 , the first driving component includes a fixed frame 701, a cylinder 702, a moving seat 703, a connecting rod 704 and a spring 705;

[0029] The fixing frame 701 is fixedly connected to the top of the base 1. The air cylinder 702 is installed on one side of the fixing frame 701. The connecting rod 704 is fixedly connected to the end of the output shaft of the air cylinder 702. The moving seat 703 is fixedly connected to the end of the connecting rod 704. The spring 705 is sleeved on the outer wall of the connecting rod 704, and both ends of the spring 705 are fixedly connected to the fixing frame 701 and the moving seat 703 respectively.

[0030] In this embodiment: When it is necessary to adjust the axial movement position of the nozzle 6, first, the air cylinder 702 is powered on and operated, so that the output shaft of the operating air cylinder 702 drives the connecting rod 704 to move outward. The moving connecting rod 704 drives the moving seat 703 to move outward. At the same time, the moving connecting rod 704 stretching the spring 705 outward, then the moving moving seat 703 drives the nozzle 6 to move outward, thus facilitating the adjustment of the axial movement position of the nozzle 6.

[0031] Please refer particularly to Figure 2 , the output shaft of the operating air cylinder 702 is used to drive the moving seat 703 to move through the connecting rod 704, and the moving moving seat 703 is used to drive the nozzle 6 to move axially.

[0032] In this embodiment: The output shaft of the operating air cylinder 702 drives the connecting rod 704 to move outward, and the moving connecting rod 704 drives the moving seat 703 to move outward.

[0033] Please refer particularly to Figure 3 , the second driving assembly includes a rotating shaft 706, a motor 707, a turntable 708, a bracket 709, a connecting shaft 7010, a swing rod 7011 and an eccentric rod 7012;

[0034] The rotating shaft 706 is rotatably connected to one side of the moving seat 703. The motor 707 is installed on the other side of the moving seat 703, and the rotating shaft 706 is fixedly connected to the end of the output shaft of the motor 707. The turntable 708 is installed at the end of the rotating shaft 706. The eccentric rod 7012 is installed on the end face of the turntable 708. The bracket 709 is fixedly connected to the end of the moving seat 703. The connecting shaft 7010 is fixedly connected to the end of the bracket 709. One end of the swing rod 7011 is rotatably connected to the connecting shaft 7010, and the eccentric rod 7012 is slidably connected to the inner wall of the swing rod 7011.

[0035] In this embodiment: By powering on and running the motor 707, the output shaft of the motor 707 in the running state drives the rotating shaft 706 to rotate. The rotating shaft 706 in the rotating state drives the turntable 708 to rotate. Then, the rotating turntable 708 drives the eccentric rod 7012 to rotate along the inner wall trajectory of the swing rod 7011. Since one end of the swing rod 7011 is rotatably connected to the connecting shaft 7010, the rotational force of the turntable 708 driving the eccentric rod 7012 is transmitted to the swing rod 7011, causing the swing rod 7011 to swing up and down reciprocally. Then, the swing rod 7011 in the swinging state drives the nozzle 6 to swing up and down reciprocally, thereby adjusting the spraying angle of the nozzle 6.

[0036] Please refer specifically to Figure 4 , the nozzle 6 is installed outside the swing rod 7011, and the output end of the delivery pipe 5 is connected to the input end of the nozzle 6.

[0037] In this embodiment: The water pump 3 in the running state inputs through the delivery pipe 5 into the nozzle 6. Then, the nozzle 6 in the up and down reciprocating swinging state sprays out the plant protection agent, effectively increasing the spraying range of the nozzle 6.

[0038] Working principle: When it is necessary to adjust the spraying angle of the nozzle 6, first power on and run the motor 707, so that the output shaft of the motor 707 in the running state drives the rotating shaft 706 to rotate. The rotating shaft 706 in the rotating state drives the turntable 708 to rotate. Then, the rotating turntable 708 drives the eccentric rod 7012 to rotate along the inner wall trajectory of the swing rod 7011. Since one end of the swing rod 7011 is rotatably connected to the connecting shaft 7010, the rotational force of the turntable 708 driving the eccentric rod 7012 is transmitted to the swing rod 7011, causing the swing rod 7011 to swing up and down reciprocally. Then, the swing rod 7011 in the swinging state drives the nozzle 6 to swing up and down reciprocally, thereby adjusting the spraying angle of the nozzle 6. At this time, the water pump 3 is powered on and runs. The water pump 3 in the running state pumps out the plant protection agent in the liquid storage tank 2 through the output pipe 4, and the water pump 3 in the running state then inputs through the delivery pipe 5 into the nozzle 6. Then, the nozzle 6 in the up and down reciprocating swinging state sprays out the plant protection agent, effectively increasing the spraying range of the nozzle 6;

[0039] When it is necessary to adjust the axial movement position of the nozzle 6, first power on and run the cylinder 702, so that the output shaft of the cylinder 702 in the running state drives the connecting rod 704 to move outward. The moving connecting rod 704 drives the moving seat 703 to move outward. At the same time, the connecting rod 704 moving outward stretches the spring 705. Then, the moving seat 703 drives the nozzle 6 to move outward, thereby facilitating the adjustment of the axial movement position of the nozzle 6.
