Embodiment 1

[0057] refer to figure 1 As shown, the pressure spraying device 100 includes a pressure spraying head 1, a first pumping device 2, a second pumping device 3, a receiving device 4, and connecting the pressure spraying head 1 and the first pumping device 2 and the first pumping device 2 respectively. And the receiving device 4, the receiving device 4 and the conduit 5 of the second pumping device 3. Wherein, the length and inner diameter of the conduit 5 are not limited, and can be designed according to requirements.

[0058] Specifically, the receiving device 4 is arranged between the first pumping device 2 and the second pumping device 3, and it includes a housing cavity 43, the bottom of the housing cavity 43 is provided with a liquid outlet 41 communicating with it, through the conduit 5 and The first pumping device 2 communicates, and the top of the receiving chamber 43 is provided with a liquid inlet 42, which communicates with the second pumping device 3 through the cond...

Embodiment 2

[0061] refer to figure 2 As shown, the difference from Embodiment 1 is that the bottom of the accommodating cavity 43 in this embodiment is cone-shaped, and the tip of the cone communicates with the first pumping device 2 through a conduit 5 . The cone shape can be conical or polygonal pyramid, so as to ensure that there is no fluid accumulation at the bottom of the accommodation chamber 43 and ensure the accuracy of flow control.

[0062] Specifically, this embodiment also includes a plurality of first pumping devices 2 and corresponding pressure nozzles 1, which divide the liquid flowing out of the liquid outlet 41 evenly through the flow equalization device 61, and flow into each pressure nozzle 1 , to achieve more efficient spraying operations. At the same time, a plurality of second pumping devices 3 may also be included, which collect the inflow liquid inlet through the converging device 62 and enter the receiving device 4, thereby increasing the overall flow rate and ...

Embodiment 3

[0065] refer to image 3 As shown, the difference from Embodiment 1 is that the bottom of the accommodating chamber 43 in this embodiment is in the shape of a truncated cone, and the catheter 5 is arranged on a plane shaped like a truncated cone, reducing the area of ​​the plane to reduce the possibility of fluid accumulation. At the same time, a detection device 7 is provided between the second pumping device 3 and the receiving device 4, or a detection device 7 can also be provided between the receiving device 4 and the first pumping device 2, for detecting the real-time flow rate of the target flow, When the real-time flow is different from the target flow, the real-time flow is used to calibrate the output flow of the second pumping device 3 until the real-time flow is equal to the target flow, so that the flow control is more precise. Specifically, it can be calibrated completely according to the size of the real-time flow, so that the real-time flow can meet the preset d...

Abstract

The invention provides a pressure spraying device and a spraying system. The pressure spraying device comprises a pressure nozzle, a first pumping device, a second pumping device and a receiving device, wherein the pressure nozzle is used for spraying fluid; the first pumping device is used for controlling the pressure of the pressure nozzle so as to atomize the fluid; the second pumping device isused for controlling the flow of the fluid which flows into the first pumping device; and the receiving device is arranged between the first pumping device and the second pumping device and comprisesa containing cavity for receiving the fluid, so that the flow of the fluid which flows from the second pumping device is equal to that of the fluid which flows into the first pumping device. According to the pressure spraying device, the problems of incapability of accurately controlling the flow and incapability of accurately spraying are solved.

Description

technical field [0001] The invention relates to the technical field of spraying, in particular to a pressure spraying device and a spraying system. Background technique [0002] With the continuous development of agricultural science and technology, the use of spraying equipment to quickly spray farmland has been more and more recognized by people. With the continuous popularization of spraying equipment and the intensification of competition, the demand for spraying controllability and accuracy of equipment is also getting higher and higher. [0003] Existing spraying equipment generally has two types of centrifugal spraying and pressure spraying. Centrifugal spraying mainly adds material liquid to the spraying plate rotating at high speed. The liquid is thrown into mist droplets at high speed by the centrifugal force on the circumference of the spraying plate. ;Compared with centrifugal spraying equipment, pressure spraying equipment greatly saves atomization power, main...
