A reed switch 15 is fixedly connected inside the two fixed connecting blocks 14. A floating alarm ball 16 is arranged inside the reed switch 15. An opening is formed on the outer surface of the reed switch 15 to facilitate the inflow of the mixed liquid medicine. When the liquid medicine in the spray box 1 is not enough, the height of the liquid medicine in the reed switch 15 will be the same as the height of the liquid medicine in the spray box 1, so as to float the floating alarm ball 16.

[0027] An audible alarm 17 is fixedly installed outside the spray box 1. The reed switch 15 and the audible alarm 17 are electrically connected by wires. The floating alarm ball 16 is made of plastic. When the liquid level in the reed switch 15 drops, the floating alarm ball 16 will also drop accordingly. When the floating alarm ball 16 drops to a certain extent, it will touch the switch inside the reed switch 15. At this time, the reed switch 15 will send a signal to the audible alarm 17, and the audible alarm 17 will start to alarm, reminding the user that the liquid medicine inside the spray box 1 is running low and needs to be replenished in time. The reed switch 15, the floating alarm ball 16, and the audible alarm 17 are all prior arts, and will not be elaborated further in this application.

[0028] Please refer to Figure 1 and Figure 2 As shown, a rubber hose 18 is fixedly connected to the outer surface of the spray box 1. The inner bottom wall of the spray box 1 is an inclined surface, which facilitates the liquid medicine inside the spray box 1 to flow into the rubber hose 18, avoiding the liquid medicine remaining in the spray box 1 and causing waste of the medicine.

[0029] One end of the rubber hose 18 is fixedly connected to a spray pipe 19. One end of the spray pipe 19 is equipped with an atomizing sprinkler head. The spray pipe 19 and the atomizing sprinkler head are all prior arts, and will not be elaborated further in this application. Through the setting of the spray pipe 19, the mixed liquid medicine in the spray box 1 can be pumped to the atomizing sprinkler head at the top of the spray pipe 19 via the rubber hose 18, and the sprinkler head can evenly spray the liquid medicine on the crops.

[0030] Two fixed clamping blocks 20 are fixedly connected to the outer surface of the spray box 1. Each fixed clamping block 20 is clamped with the spray pipe 19. When the spray pipe 19 is not in use, it can be hung on the fixed clamping block 20, reducing the space occupied by the device when it is idle and facilitating storage and handling.

[0031] Please refer to Figure 4 As shown, a top cover 2 is provided above the spray box 1. Two threaded ports 3 are opened on the top surface of the top cover 2. A threaded cover 4 is threadedly connected inside each threaded port 3. After the medicine is poured into the spray box 1, screwing the threaded cover 4 into the threaded port 3 can keep the device airtight. At this time, stirring the liquid medicine will not cause the medicine to volatilize outside the spray box 1, avoiding the volatilization and loss of the medicine and protecting the health and safety of the users.

[0032] A pouring port 10 adapted to the threaded port 3 is opened on the top surface of the spray box 1. Through the settings of the threaded port 3 and the pouring port 10, it is convenient for the user to pour medicines such as nutrient solution or water into the inside of the spray box 1 for mixing.

[0033] Inside the top cover 2, a rotating rod 5 is rotatably connected. At the bottom end of the rotating rod 5, a fixed clamping block 6 is fixedly connected. Inside the connecting sleeve 8, a driven rotating rod 9 is rotatably connected. On the top surface of the driven rotating rod 9, a clamping groove is formed. The fixed clamping block 6 is adapted to the clamping groove. When the rotating rod 5 rotates, it can drive the fixed clamping block 6 to rotate. When the fixed clamping block 6 rotates, due to the clamping effect with the driven rotating rod 9, the driven rotating rod 9 will also rotate accordingly, thereby driving the subsequent drug stirring operation.

[0034] On the top surface of the rotating rod 5, a rotating disk 7 is fixedly connected. On the top surface of the rotating disk 7, a crank is installed, which is convenient for the user to rotate the rotating disk 7 through the crank. When the rotating disk 7 rotates, it can drive the rotating rod 5 to rotate inside the top cover 2, thereby providing a power source for the subsequent drug stirring operation.

[0035] On the top surface of the spray box 1, a connecting sleeve 8 is fixedly connected. On the bottom surface of the top cover 2, a clamping hole is formed. The connecting sleeve 8 is adapted to the clamping hole. Through the clamping of the connecting sleeve 8 and the clamping hole, it is convenient for the user to place the top cover 2 on the spray box 1, providing convenience for cleaning the residual liquid medicine inside the spray box 1.

[0036] Please refer to Figure 2 The driven rotating rod 9 passes through the spray box 1 and is rotatably connected to the spray box 1. On the outer surface of the driven rotating rod 9, a group of fixed collar rings 11 arranged in a linear array are fixedly connected. On the outer surface of each fixed collar ring 11, a group of stirring rods 12 arranged in a circumferential array are fixedly connected. When the driven rotating rod 9 rotates, it can drive the fixed collar rings 11 to rotate. When the fixed collar rings 11 rotate, they can drive the stirring rods 12 to rotate, thereby driving the rotation of the liquid medicine inside the spray box 1, enabling the liquid medicine inside the spray box 1 to be fully mixed and avoiding the uneven mixing of drugs from affecting the growth of crops.

[0037] When the present utility model is in use: First, rotate the threaded cap 4 to remove the threaded cap 4 from the threaded port 3. Then, pour drugs and materials such as water into the spray box 1 through the threaded port 3. Then, thread the threaded cap 4 onto the threaded port 3. Then, rotate the rotating disk 7 through the crank. When the rotating disk 7 rotates, it can drive the rotating rod 5 to rotate. When the rotating rod 5 rotates, it drives the fixed clamping block 6 to rotate. Due to the clamping action between the fixed clamping block 6 and the driven rotating rod 9, the driven rotating rod 9 will also rotate inside the spray box 1 as the fixed clamping block 6 rotates. When the driven rotating rod 9 rotates, it can drive the fixed collar rings 11 to rotate. When the fixed collar rings 11 rotate, they drive the stirring rods 12 to rotate, thereby enabling the liquid medicine inside the spray box 1 to be fully mixed and avoiding the uneven mixing of drugs from affecting the growth of crops. During the mixing process, the inside of the spray box 1 remains sealed to prevent drug volatilization and reduce the cost of crop planting.
