Description

Technical Field

[0001] The utility model relates to the technical field of sprinklers, in particular to a sprinkler with a protective function. Background Art

[0002] With the development of society, agriculture has begun to scale up and industrialize. In the agricultural production process, agricultural greenhouses are often used to meet the production conditions of some crops. At the same time, crops need to be sprayed with pesticides regularly. At this time, a universal sprayer is needed to spray crops energy-savingly. The sprayer sprays the solution in a mist or droplet form onto the crops to control the crops and prevent pests from harming them and affecting their yield. Among them, the "a pesticide spraying device with seedling protection function" disclosed in the application number "CN218736798U" has solved the problem. In actual use, although the scope of pesticide spraying is limited, if the operator is not careful, it will still be sprayed on the seedlings. However, in actual use, sprayers with protective functions of similar structures still have many defects, such as: they do not have a protective function, resulting in the spread of pesticide liquid to the skin of the staff with the wind after the personnel operate the device, which is prone to the risk of poisoning; they do not have the function of retracting the water pipe, resulting in the water pipe being too long and easy to be entangled and affecting the movement of the device, reducing the service life of the water pipe, so it is necessary to design a sprayer with a protective function.

DETAILED DESCRIPTION

[0021] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments. Embodiment 1

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the utility model proposes a sprayer with a protective function, comprising a liquid storage tank 1, a reel 5 and a protective cover 7, a liquid level tube 104 is installed through one side of the liquid storage tank 1, and a liquid inlet 103 is fixedly installed on the other side of the top of the liquid storage tank 1, a liquid outlet valve 106 is fixedly installed on one side of the top of the liquid storage tank 1, a liquid guide tube 101 is installed through the bottom of the liquid outlet valve 106, a support frame 4 is fixedly installed on the top of the liquid outlet valve 106, a handheld spray rod 6 is installed in the support frame 4, a filter 602 is installed on the top of the handheld spray rod 6 through a serpentine tube 601, and a spray head 603 is fixedly installed on the top of the filter 602;

[0023] A protective cover 7 is fixedly installed on one side of the top of the support frame 4, a protective fan 701 is fixedly installed on one side of the protective cover 7, a reel 5 is rotatably installed on one side of the support frame 4, a hose 502 is installed around the inside of the reel 5, and a connector 503 is fixedly installed on one end of the hose 502, a crank 501 is fixedly installed on one side of the reel 5, and a mounting shaft frame 2 is fixedly installed on one side of the bottom of the liquid storage tank 1;

[0024] Rollers 201 are installed on both sides of the mounting shaft frame 2 through shaft rods, a limiting member 202 is fixedly installed on one side of the mounting shaft frame 2, a pull rod 3 is installed on the top of the mounting shaft frame 2 through a shaft bolt, an adjusting knob 301 is threadedly installed on the front surface of the pull rod 3, and an extended extension rod 302 is installed inside the pull rod 3, a high-pressure pump 801 is fixedly installed inside the mounting box 8, and a pressure gauge 802 is installed on the output end of the high-pressure pump 801 through a delivery pipe, and a controller 803 is fixedly installed on the top of the mounting box 8.

[0025] The working principle of the sprayer with protection function based on the first embodiment is as follows: liquid medicine can be added to the liquid storage tank 1 through the liquid inlet 103, and the liquid storage amount in the liquid storage tank 1 can be easily observed through the liquid level tube 104, so that the staff can accurately dispense medicine. The controller 803 controls the high-pressure pump 801 to be powered on and run. The high-pressure pump 801 that is powered on and runs generates high-pressure air and delivers it to the liquid storage tank 1 through the delivery pipe, so that the liquid storage tank 1 forms a high pressure. At the same time, the pressure gauge 802 monitors the internal air pressure of the liquid storage tank 1 in real time, and transmits the monitoring electrical signal to the controller 803 for calculation. When the calculation result of the controller 803 reaches the set value, the controller 803 controls the high-pressure pump 801 to stop running, thereby ensuring the safety of the internal air pressure of the liquid storage tank 1.

[0026] The liquid outlet valve 106 is controlled to open by the controller 803, and the liquid can be transported to the liquid outlet valve 106 through the liquid guide tube 101 through the internal high pressure of the liquid storage tank 1, and the liquid can be transported to the handheld spray rod 6 through the hose 502. The impurities in the liquid can be filtered through the filter 602 to ensure the safety of the nozzle 603, and then the liquid can be evenly atomized through the nozzle 603 to achieve uniform spraying of the liquid, and the elevation angle and spraying direction of the nozzle 603 can be adjusted through the serpentine tube 601, so that the nozzle 603 can be adjusted to spray at an angle.

[0027] The protective cover 7 can block the liquid medicine for the workers, effectively preventing the liquid medicine from falling on the workers' skin and causing harm, thereby ensuring the safety of the workers. At the same time, the protective fan 701 is powered on to generate wind force, which can blow the liquid medicine sprayed by the nozzle 603, which can not only increase the liquid medicine delivery distance, but also blow the liquid medicine away from the workers, further improving the safety of the workers and increasing the protection function of the device.

[0028] The reel 502 is driven to reel and unreel by rotating the crank 501, and the rotating reel 5 drives the hose 502 to reel and unreel. The reeling hose 502 can increase the orderliness of storage, avoid the hose 502 from being entangled, and facilitate the movement of the device. At the same time, the unreeling hose 502 can adjust the use length of the hose 502, which is convenient for adjusting the length of the hose 502 according to the use mode of the handheld spray rod 6, so that the staff can hold the spray rod 6 for remote handheld operation;

[0029] The adjusting knob 301 is turned to move away from the extension rod 302, and the extension rod 302 is then pulled to adjust the extension length. The extension rod 302 is fixed by turning the adjusting knob 301 to ensure the stability of the extension length of the extension rod 302, so that the device can be adjusted according to the height of the user. The pull rod 3 is moved by holding the extension rod 302 so that the pull rod 3 can be limited by the limit piece 202, so that the pull rod 3 can be tilted with the axis point of the roller 201 to move the device. The roller 201 is used to facilitate the movement of the device, so that the staff can move the device flexibly. Embodiment 2
