The drone 1 is a prior art and can start working by turning on the power supply. It can be realized by personnel in this field. Due to the prior art, this case will not be described in detail. A water tank 2 for storing liquid is installed on the top of the drone 1. Before the spraying operation, the water tank 2 needs to be filled with the liquid to be sprayed. The bottom of the water tank 2 is installed with a water pump 6 for driving the liquid from the water tank 2 to the storage tank 31. The bottom of the drone 1 is provided with a device for controlling quantitative spraying. The control component 3 includes a storage box 31 for temporarily storing spraying liquid, the top of the storage box 31 is fixedly connected to the bottom of the drone 1, the left end of the control component 3 is provided with an adjustment component 4 for adjusting the internal volume of the storage box 31, the bottom of the storage box 31 is fixedly connected with a water outlet 33 for discharging the liquid inside the storage box 31, the outer wall of the water outlet 33 is installed with a nozzle 5 for spraying liquid, the top of the storage box 31 is installed with a water inlet 32 ​​for supplying liquid to the inside of the storage box 31, and the top of the water inlet 32 ​​is installed at the bottom end of the water pump 6.

[0032] Reference Figure 2 - Figure 4 The adjusting assembly 4 includes a slide bar 41 for driving a sealing block 46 to move. The slide bar 41 penetrates and is slidably connected to the left end of the storage box 31. The right end of the slide bar 41 is fixedly connected to a sealing block 46 for adjusting the internal space of the storage box 31. The sealing block 46 can be driven to move left and right by moving the slide bar 41. The sealing block 46 is slidably connected to the inner wall of the storage box 31. When the sealing block 46 moves left and right inside the storage box 31, the internal volume of the storage box 31 will also change accordingly. The left end of the storage box 31 is fixedly connected to an adjusting box 45 for accommodating an adjusting spring 48. The top of the adjusting box 45 A lever 47 for fixing the slide bar 41 is passed through and slidably connected at the end. An adjusting hole 44 for accommodating the lever 47 is provided at the top of the slide bar 41. The adjusting hole 44 and the lever 47 are adapted to each other. When the lever 47 is inserted into the adjusting hole 44, the slide bar 41 will be fixed and cannot move left or right. A pressure plate 49 for driving the lever 47 to reset is fixedly connected to the outer wall of the lever 47. An adjusting spring 48 for pressing the pressure plate 49 downward is fixedly connected to the top of the pressure plate 49. The top of the adjusting spring 48 is fixedly connected to the inner wall of the adjusting box 45. The adjusting spring 48 will always push the pressure plate 49 downward.

[0033] Reference Figure 1 - Figure 3The inner wall of the storage box 31 is fixedly connected with a sealing box 37 for accommodating a return spring 39. The top of the sealing box 37 passes through and is slidably connected with a connecting rod 35 for connecting an upper baffle 34 and a lower baffle 36. The top of the connecting rod 35 is fixedly connected with an upper baffle 34 for closing the water inlet 32. The bottom end of the connecting rod 35 is fixedly connected with a lower baffle 36 for closing the water outlet 33. When the water pump 6 supplies water to the interior of the storage box 31, the liquid will squeeze the upper baffle 34 to move downward, and the upper baffle 34 will squeeze the lower baffle 36 through the connecting rod 35. The lower baffle 36 will move downward to close the water outlet 33. The outer wall of the connecting rod 35 is fixedly connected with a connecting rod 35 for driving the connecting rod 35 to move. The slide plate 38 is slidably connected to the inner wall of the sealing box 37. The top of the slide plate 38 is fixedly connected to a return spring 39 for driving the slide plate 38 to move and return. The top of the return spring 39 is fixedly connected to the inner wall of the sealing box 37. The return spring 39 will always pull the slide plate 38 upward. The left end of the slide rod 41 is fixedly connected to an indicator plate 42 for prompting the operator of the internal volume size of the storage box 31. The indicator plate 42 is slidably connected to the left end of the storage box 31. The front end of the storage box 31 is provided with a scale line 43 for use with the indicator plate 42. By observing the positions of the indicator plate 42 and the scale line 43, the volume size inside the storage box 31 at this time can be clearly seen.

[0034] Working principle: When spraying operation is required, it is necessary to first fill the water tank 2 with spray liquid, and then pull the lever 47 upward to move it upward and out of the adjustment hole 44, and then move the slide bar 41 left and right to drive the sealing block 46 to move left and right inside the storage box 31, so that the volume of the storage box 31 can be changed. At the same time, by comparing the positions of the indicator plate 42 and the scale line 43, the size of the internal volume of the storage box 31 can be clearly determined. When the volume is adjusted, the lever 47 can be released, and the adjustment spring 48 will drive the lever 47 to move downward by pushing the pressure plate 49 to re-enter the adjustment hole 44, and re-fix the slide bar 41.

[0035] During the spraying operation, when liquid needs to be sprayed, it is necessary to first start the water pump 6 to drive the liquid from the inside of the water tank 2 into the inside of the storage box 31 through the water inlet 32. When the liquid passes through the water inlet 32, it will squeeze the upper baffle 34. The upper baffle 34 will drive the lower baffle 36 to move downward through the connecting rod 35 to close the water outlet 33. In this way, the liquid will accumulate in the storage box 31. When the inside of the storage box 31 is full, the water pump 6 can be turned off. The return spring 39 will drive the upper baffle 34 to move upward by pulling the slide plate 38 to close the water inlet 32. At the same time, the connecting rod 35 will pull the lower baffle 36 to open the water outlet 33. At this time, the liquid in the storage box 31 will enter the inside of the nozzle 5 through the water outlet 33 and be discharged through the nozzle 5.
