[0039] It should be noted that: by opening the through slot 212, when the connecting strip 231 is rotated by the driving force later, the through slot 212 can make the connection inside the installation frame 21 rotate, so that the device can drive the semi-annular conduit 3 to rotate later, and control the position between the two semi-annular conduits 3;

[0040] It should also be noted that: the installation frame 21 and the connecting strip 231 and the through groove 212 can also be covered with a protective cover of a flexible structure, which effectively prevents tobacco leaves of the tobacco plant or external weeds from getting stuck in the through groove 212 and causing the mechanism to be blocked, and ensures that the connecting strip 231 rotates smoothly in the later stage;

[0041] Through the connection between the guide ring and the connecting rope 223, when the connecting rope 223 is moved by the driving force, the guide ring 211 can guide the moving trajectory of the connecting rope 223, thereby improving the later movement stability of the connecting rope 223 and enabling it to drive the semi-annular catheter 3.

[0042] The working principle of the tobacco plant root and stem ring spraying device provided by the utility model is as follows:

[0043] When the device is used later, the liquid conduit 32 in the device can be connected to the output end of the pump body in the external liquid outlet box, and the electric push rod 22 and the switch 43 can be electrically connected to the battery in the liquid storage tank;

[0044] After completing the installation of the device, the staff can first place the arm on the outer wall of the support plate 5, and then wrap the arm and the support plate 5 through the strap 51. At this time, the strap 51 can be smoothly adhered through the Velcro fur surface and Velcro hook surface on the outer wall, so that the arm and the support plate 5 can be tied and fixed;

[0045] After the binding between the support plate 5 and the arm is completed, the staff can control the position of the device by holding the outer wall of the support tube 1 with the palm. When the semi-annular guide tube 3 moves to the outside of the tobacco plant root, the staff can push the driving ring 44 with the fingers. At this time, the moving driving ring 44 can be squeezed with the switch 43 to control the electric push rod 22 to retract.

[0046] At this time, the retracted electric push rod 22 can drive the semi-annular conduit 3 to rotate through the connection part of the rotating cylinder 23 and the vertical rod 213 through the connecting rod 221, the sliding sheet 222 and the connecting rope 223, so that the two semi-annular conduits 3 can move back to each other to complete the expansion. When the semi-annular conduits 3 are expanded and separated, the staff can move the semi-annular conduits 3 to the outside of the tobacco plant root and at the same time release the squeezing of the driving ring 44 and control the water pump in the liquid storage tank to work;

[0047] When the driving ring 44 releases the pressure on the switch 43 to reset and extend the electric push rod 22, the first spring 24 can reset the connecting piece 232 through its own driving force, and can drive the rotating cylinder 23 to reset and rotate on the outer wall of the vertical pole 213 through the connecting piece 232, so that the two semi-annular guide tubes 3 can be smoothly reset to form an annular structure liquid guide tube 32 on the outside of the tobacco plant rhizome, and the working water pump can spray the liquid in the liquid storage tank to the outside of the tobacco plant rhizome through the semi-annular guide tube 3 and the nozzle 31.

[0048] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0049] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
