Description

Technical Field

[0001] This utility model relates to the field of sprayer technology, specifically a pressure monitoring and supplementary device for sprayers. Background Technology

[0002] A pesticide sprayer is an agricultural implement that mixes water and pesticide solution and sprays the liquid onto the surface of an object under pressure. It is a type of agricultural pesticide application machinery.

[0003] Currently, in order to ensure the effectiveness of spraying, sprayers typically install pressure sensors on the outlet pipe to monitor the pressure inside the pipe. However, this single monitoring method can only determine the pressure inside the outlet pipe and cannot detect whether the amount of pesticide in the storage tank is insufficient. It forces workers to infer the pesticide usage in the tank based on time, making it inconvenient for precise maintenance. Therefore, we propose a pressure monitoring and replenishment device for sprayers. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0024] Example 1:

[0025] Please see Figures 1-6 In this embodiment of the present invention, a pressure monitoring and replenishment device for a sprayer includes: a base plate 1, a placement groove on the top of the base plate 1, a weighing mechanism 3 inside the placement groove, the weighing mechanism 3 extending to the top of the base plate 1, a liquid tank fixed on the weighing mechanism 3, a control mechanism 2, a pressurizing mechanism 4 and a liquid adding mechanism 8 respectively on the top of the base plate 1, the pressurizing mechanism 4 and the liquid adding mechanism 8 being connected to the top of the liquid tank, a spraying assembly 5 connected to the outer surface of the liquid tank, a pressure sensor 6 connected to the spraying assembly 5, and a detection mechanism 7 connected to the top of the liquid tank, the detection mechanism 7 extending into the interior of the liquid tank.

[0026] Specifically, when the pressure sensor 6 detects an excessive pressure change in the spraying assembly 5, it will send feedback to the control mechanism 2, causing the control mechanism 2 to sound a beep. Then, by observing the weighing mechanism 3, the volume of the liquid inside the liquid tank is determined. Finally, the pressurizing mechanism 4 can be activated to inject air into the liquid tank, thereby increasing the pressure inside the liquid tank and allowing the spraying assembly 5 to better extract the liquid, thus avoiding affecting the spraying effect of the spraying assembly 5. The liquid is then delivered to the inside of the liquid tank through the liquid adding mechanism 8. The amount of liquid can be monitored by the continuously rising detection mechanism 7. When the liquid inside the liquid tank reaches a certain level, the detection mechanism 7 sends feedback to the control mechanism 2 to close the liquid adding mechanism 8, thereby completing the quantitative liquid addition inside the liquid tank.

[0027] Example 2:

[0028] Please see Figures 3-5 In this embodiment of the present invention, a pressure monitoring and replenishment device for a sprayer includes a control mechanism 2 comprising a control box 201 and an alarm box 202. The control box 201 is connected to the top of the base plate 1 and contains a controller. The alarm box 202 is connected to the top of the base plate 1, and both the alarm box 202 and the pressure sensor 6 are electrically connected to the controller. The weighing mechanism 3 includes a weighing plate 301, a limiting frame 302, and a display screen 303. The weighing plate 301 is connected to the bottom of the inner wall of the placement groove, and the limiting frame 302 is connected to the top of the weighing plate 301. The outer surface of the limiting frame 302 is attached to the inner wall of the placement groove and extends to the top of the base plate 1. The display screen 303 is connected to the bottom of the inner wall of the placement groove and is connected to the weighing plate 301 and extends to the top of the base plate 1. The pressurizing mechanism 4 includes a pressurizing pump 401 and a connecting pipe 402. The pressurizing pump 401 is connected to the top of the base plate 1. The connecting pipe 402 is connected to the air outlet of the pressurizing pump 401. One end of the connecting pipe 402 extends to the top of the medicine tank and is connected to the top of the medicine tank. An air inlet valve is connected to the outer surface of one end of the connecting pipe 402.

[0029] Specifically, firstly, observe the display screen 303, which can display the total weight of the liquid tank through the weighing plate 301. When the pressure sensor 6 detects that the pressure inside the spraying assembly 5 is too low, the pressure sensor 6 will send feedback to the controller inside the control box 201, causing the controller to operate the alarm box 202 to sound a buzzer as a reminder. Next, observe the display screen 303 to infer the volume of liquid inside the liquid tank. If the liquid is not insufficient, start the pressurizing pump 401 and open the air inlet valve. The pressurizing pump 401 injects air into the liquid tank through the connecting pipe 402 to increase the air pressure inside the liquid tank. At this time, the liquid inside the liquid tank can be discharged through the spraying assembly 5 under the action of air pressure, thereby restoring the normal liquid pumping and spraying operation of the spraying assembly 5.

[0030] Example 3:

[0031] Please see Figures 1-6 In this embodiment of the present invention, a pressure monitoring and replenishment device for a sprayer includes a detection mechanism 7 comprising a slide rod 701, a first electromagnetic plate 702, a U-shaped frame 703, a second electromagnetic plate 704, and a floating ball 705. The slide rod 701 is slidably connected to the top of the liquid tank, and the bottom end of the slide rod 701 extends into the interior of the liquid tank. The first electromagnetic plate 702 is connected to the top of the slide rod 701. The U-shaped frame 703 is connected to the top of the liquid tank. The second electromagnetic plate 704 is connected to the top of the inner wall of the U-shaped frame 703. The first electromagnetic plate 702 and the second electromagnetic plate 704 are electrically connected. The second electromagnetic plate 704 is electrically connected to the controller. The floating ball 705 is connected to the bottom end of the slide bar 701. The liquid adding mechanism 8 includes a water pump 801 and a liquid adding pipe 802. The water pump 801 is connected to the top of the base plate 1 and is electrically connected to the controller. The liquid adding pipe 802 is connected to the output end of the water pump 801, and one end of the liquid adding pipe 802 extends to the top of the medicine tank and is connected to the top of the medicine tank. A water valve is connected to the outer surface of one end of the liquid adding pipe 802. Two push handles 9 are connected to the top of the base plate 1, and multiple casters 10 are connected to the bottom of the base plate 1.

[0032] Specifically, the water pump 801 is started and the water valve is opened. The water pump 801 delivers the medicine to the inside of the medicine tank through the liquid filling pipe 802. As the medicine level rises, it will cause the floating ball 705 to rise, thereby causing the slide bar 701 to slide upward inside the base plate 1. When the first electromagnetic plate 702 contacts the second electromagnetic plate 704, the second electromagnetic plate 704 will send feedback to the controller. The controller will then turn off the water pump 801, and the medicine in the medicine tank will be added to the normal usage amount, completing the automated dosing. The two pushers 9 can push the base plate 1 to rotate the multiple casters 10, thereby moving the device.

[0033] The working principle of this utility model is as follows: The medicine tank is fixed to the top of the weighing plate 301 by the limiting frame 302. The display screen 303 shows the total weight of the medicine tank. Then, the spraying assembly 5 is activated to extract the medicine from the tank and spray it onto the desired ground. When the pressure sensor 6 detects an excessive pressure change in the spraying assembly 5, it sends feedback to the controller inside the control box 201, causing the controller to activate the alarm box 202 to sound an alarm, thus alerting the staff. The staff then observes the display screen 303 to estimate the volume of medicine in the tank. If the medicine is not insufficient, the staff activates the pressurizing pump 401 and opens the air inlet valve. The pressurizing pump 401 then pumps air into the medicine tank through the connecting pipe 402. Injecting air increases the air pressure inside the liquid tank. Under this pressure, the liquid in the tank can be discharged through the spraying assembly 5, thus restoring the normal liquid pumping and spraying operation of the spraying assembly 5. When the liquid in the tank is insufficient, the operator connects the input end of the water pump 801 to the inlet pipe, starts the water pump 801, and opens the water valve to deliver the liquid into the tank. The floating ball 705 floats as the liquid level rises, causing the slide bar 701 to slide upward inside the base plate 1. When the first electromagnetic plate 702 contacts the second electromagnetic plate 704, the second electromagnetic plate 704 sends feedback to the controller, which then shuts off the water pump 801. At this point, the normal usage amount of liquid can be added to the tank, completing the automated dosing process.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
