This plant protection root irrigation device irrigates the roots by inserting the root irrigation tube into the soil near the seedlings, allowing liquid to flow into the ground. This ensures that the liquid reaches the roots of the seedlings and ensures effective root irrigation. However, this device requires a worker to carry the water tank on their back during root irrigation, which increases labor intensity. Furthermore, the device cannot control the amount of reducing agent used during root irrigation; excessive or insufficient reducing agent can affect tobacco growth.

[0003] Therefore, it is necessary to propose a tobacco herbicide damage reduction root irrigation device to solve the above problems. Utility Model Content

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Example 1: This example 1 provides a tobacco herbicide damage reduction root irrigation device, which is directly improved on the existing plant protection root irrigation device and has a unique structure. Figure 1-3As shown, it includes a trolley 1, a liquid storage tank 2, a connecting pipe 3 and a quantitative root irrigation device. The liquid storage tank 2 is fixedly installed on the trolley 1, and a feed port 23 is opened on the top of the liquid storage tank 2. A stirring mechanism is provided in the liquid storage tank 2, and the stirring mechanism includes a motor 20 fixedly installed on the top of the liquid storage tank 2, and also includes a rotating shaft 21 rotatably installed in the liquid storage tank 2, and a plurality of stirring rods 22 are fixedly installed on the rotating shaft 21 at vertical intervals. The top of the rotating shaft 21 passes through the liquid storage tank 2 and is fixedly connected to the output shaft of the motor 20; the quantitative root irrigation device includes an installation box 4, a liquid storage cylinder 5, a three-way pipe 6, a cannula 7 and a quantitative mechanism arranged in the installation box 4, which are fixedly connected from left to right. A handle 18 is fixedly installed on the top of the installation box 4, and a control button 19 is provided on the handle 18. The lower end of the three-way pipe 6 is connected to the bottom of the liquid storage tank 2 through the connecting pipe 3;

[0018] The power supply 17 supplies power to the drive motor 8 through the control button 19, and the control button 19 is used to control the start and stop of the drive motor 8. The connecting pipe 3 is fixed to the installation box 4 by a clamp, and the two ends of the connecting pipe 3 are threadedly connected to the liquid storage tank 2 and the tee pipe 6 respectively, and the tee pipe 6 is threadedly connected to the insert pipe 7; a one-way liquid inlet valve is provided in the lower port of the tee pipe 6, and a one-way liquid outlet valve is provided in the right port of the tee pipe 6. A conical hollow plug is provided at the end of the insert pipe 7 away from the tee pipe 6, and a plurality of liquid outlets are evenly provided on the plug; the quantitative mechanism includes a drive motor 8, a drive shaft 10, a power supply 17 and a slide rod 13 installed in the installation box 4 along a transverse sliding manner, one end of the slide rod 13 extends into the liquid storage cylinder 5 and is fixedly installed with a piston 16, and the drive shaft 10 is concentrically fixedly installed on the output shaft of the drive motor 8.

[0019] Through the deceleration and torque-increasing effect of the reducer 9, the drive motor 8 can output sufficient torque to drive the drive shaft 10 to rotate, thereby increasing the transmission distance of the reducing agent. There are many ways to install the drive shaft 10, for example: a fixed plate 12 is fixedly installed in the installation box 4, and both ends of the drive shaft 10 are rotatably installed on the fixed plate 12 and the right inner wall of the installation box 4 through bearings. A through hole is provided on the fixed plate 12, and the slide rod 13 is slidably mounted in the through hole; an elliptical drive groove 11 is provided on the outer ring surface of the drive shaft 10, and the two ends of the drive groove 11 are respectively located on both sides of the drive shaft 10, and a drive rod 15 is slidably installed in the drive groove 11, and the other end of the drive rod 15 is fixedly connected to the slide rod 13. There are many ways to connect the drive rod 15 to the slide rod 13, for example: a connecting ring 14 is fixedly mounted on the slide rod 13, and the drive rod 15 is fixedly connected to the connecting ring 14.

[0020] When we use this device to irrigate the roots of tobacco, we first pour the reducing agent and water into the liquid storage tank 2 through the feed port 23, and then start the motor 20. The motor 20 is electrically connected to the external power supply. The motor 20 drives the rotating shaft 21 to rotate, thereby driving the stirring rod 22 to mix and stir the solution in the liquid storage tank 2. After mixing evenly, the staff holds the handle 18 to move the quantitative irrigation device to the vicinity of the tobacco that needs to be irrigated, inserts the plug of the cannula 7 into the soil near the tobacco root system, and presses the control button 19. At this time, the drive motor 8 drives the drive shaft 10 to rotate through the reducer 9. Since the drive rod 15 is slidably installed in the drive groove 11, and the other end of the drive rod 15 is fixedly connected to the slide rod 13, the drive shaft 10 rotates. During the process, the slide bar 13 will be driven to move back and forth left and right. In addition, since a one-way liquid inlet valve is provided in the lower port of the tee pipe 6 and a one-way liquid outlet valve is provided in the right port of the tee pipe 6, when the slide bar 13 moves to the left, a negative pressure will be generated between the piston 16 and the tee pipe 6, thereby sucking the solution in the liquid storage tank 2 into the liquid storage cylinder 5 through the lower port of the tee pipe 6. When the slide bar 13 moves to the right, the piston 16 can press the solution in the liquid storage cylinder 5 into the cannula 7 and inject it into the soil near the tobacco root system through the cannula 7, thereby completing the root irrigation operation. By using the quantitative root irrigation device, the reducer can be remotely and quantitatively injected into the soil near the tobacco root system, which can not only reduce the labor intensity of the operator, but also better eliminate the influence of the herbicide on the tobacco root system.

[0021] Example 2: The difference between Example 2 and Example 1 is that a plurality of electric push rods are fixedly installed on the bottom of the trolley 1, and the plurality of electric push rods are distributed in a rectangular shape, and anti-slip pads are fixedly installed on the lower ends of the electric push rods. The universal wheels at the bottom of the trolley 1 can be separated from the ground through the electric push rods, thereby preventing the trolley from moving during root irrigation.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
