[0018] The specific embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0019] By Figures 1 to 4The utility model discloses a root irrigation pipe, which comprises an upper shell plate 1, a root irrigation pipe 2 fixed in the middle of the upper shell plate 1, a pipe penetrating through the lower end surface of the upper shell plate 1, a conical block with a pointed end fixed at the lower end of the root irrigation pipe 2, a plurality of water seepage holes 3 arranged at the lower side of the outer edge surface of the root irrigation pipe 2, each column of water seepage holes 3 being arranged at equal intervals, a vertical rod 4 arranged at the corresponding position of each column of water seepage holes 3 on the inner side of the root irrigation pipe 2, a plurality of blocking blocks 5 fixed on each vertical rod 4, the blocking blocks 5 corresponding to the water seepage holes 3 one by one, the outer edge surface of the blocking blocks 5 being attached to the root irrigation pipe 2 and being capable of blocking the water seepage holes 3, the vertical rod 4 being capable of driving all the blocking blocks 5 in the same column to move upward synchronously and opening the corresponding water seepage holes 3 when the vertical rod 4 moves upward, a horizontal rod 6 penetrating through the upper end surface of the upper shell plate 1 and being fixedly connected to the upper end of each vertical rod 4, the horizontal rod 6 being always subjected to a downward thrust, and the position of the horizontal rod 6 being capable of being fixed after the horizontal rod 6 moves upward by a specified height.

[0020] A vertical shaft 7 is fixed in the middle of the upper end surface of the upper shell plate 1, the outer edge surface of the vertical shaft 7 being attached to the inner side surface of the vertical rod 4, a plurality of groups of horizontal holes 8 being arranged on the vertical shaft 7 at the corresponding positions of each vertical rod 4, a blind hole 9 being arranged on the upper end surface of the vertical shaft 7, all the horizontal holes 8 at the same height being communicated with the blind hole 9, a pin shaft 10 capable of sliding horizontally being arranged in each horizontal hole 8, the outer end of the pin shaft 10 extending out of the outer side of the horizontal hole 8 and the outer end surface being inclined, the vertical rod 4 being capable of driving the pin shaft 10 to move into the inner side of the horizontal hole 8 by extruding the inclined surface when the vertical rod 4 moves upward, a pin shaft hole 11 being arranged on the upper end of the inner side surface of the vertical rod 4, and the outer end of the pin shaft 10 being capable of being arranged in the pin shaft hole 11 to limit the downward movement of the vertical rod 4.

[0021] A pull ring 12 is arranged at the outer end of the blind hole 9, a pull rope 13 being connected to the lower end of the pull ring 12, and the pull rope 13 being fixedly connected to each pin shaft 10 by penetrating through the blind hole 9 and the horizontal hole 8.

[0022] A slide rod 14 vertically arranged is fixed to the outer end of the horizontal rod 6, the lower end of the slide rod 14 penetrating through the lower end surface of the upper shell plate 1 and being capable of sliding upward and downward, the slide rod 14 being capable of limiting the end part of the horizontal rod 6, so that the horizontal rod 6 can always keep a horizontal state and move upward and downward, and the horizontal rod 6 is ensured to be horizontally projected to coincide with the L-shaped rod, thereby being convenient for an operator to pull the horizontal rod 6 upward.

[0023] A plurality of L-shaped rods 15 are fixed to the upper end surface of the upper shell plate 1, the horizontal part of the L-shaped rod 15 being located above the horizontal rod 6, a compression spring being arranged between the horizontal rod 6 and the L-shaped rod 6, and the compression spring always giving the horizontal rod 6 a downward thrust.

[0024] A water inlet pipe 16 is fixed to the outer edge surface of the root irrigation pipe 2, and the water inlet pipe 16 is communicated with the cavity of the root irrigation pipe 2.

[0025] In use, the inlet pipe 16 is first connected to the supply pipe. Because the vertical rod 4 and horizontal rod 6 are always at their lowest ends under the action of the compression spring, the plug 5 always blocks the seepage hole 3. The entire device is moved to the area requiring drip irrigation. Then, by pressing down on the L-shaped rod 15, the lower end of the root irrigation tube 2 is inserted into the soil. Next, the horizontal rod 6 near the tobacco seedling is pulled upwards with a finger, causing the horizontal rod 6 to overcome the spring force and move the vertical rod 4 upwards. The vertical rod 4 then moves all the plugs 5 in the same row upwards, opening the seepage hole 3. Water can then enter the soil through the opened seepage hole 3 to drip irrigate the roots of the tobacco leaves. As the vertical rod 4 moves upwards, because the vertical shaft is equipped with multiple vertical and horizontal plugs... The pin 10 is used to prevent the pin hole 11 on the vertical rod 4 from resetting downwards when it is moved to any height position. Therefore, the operator only needs to pull the vertical rod 4 upwards a certain distance using the horizontal bar 6 and then release it, keeping the seepage hole 3 open. When the drip irrigation volume is sufficient, simply pull the pull ring 12 upwards, and all the pins 10 can move inwards towards the horizontal hole 8 under the pulling force of the pull rope 13, causing the pins 10 originally placed in the pin hole 11 to disengage from the pin hole 11. The vertical rod 4 can then reset downwards under the pushing force of the compression spring, causing the block 5 to re-block the seepage hole 3. Then, the root irrigation tube 2 can be pulled out upwards using the horizontal bar L-shaped rod 15.

[0026] This invention seals the seepage holes 3 with blocking blocks 5, preventing soil from entering the root irrigation tube 2 through the seepage holes 3 after insertion, thus avoiding blockage and significantly extending the service life of the drip irrigation device. Multiple sets of seepage holes 3 are evenly distributed around the circumference, and the vertical rod 4 controls the up-and-down movement of all blocking blocks 5 in the same row to open or close the seepage holes 3. This allows for easy manual control of the water flow direction, concentrating the water flow towards the roots of the tobacco leaves, greatly improving irrigation efficiency and preventing water waste. Multiple sets of pins 10 are installed on the vertical shaft 7, allowing the vertical rod 4 to be fixed at different heights when moving upwards. This facilitates operator control of the opening size of the seepage holes 3, thereby changing the seepage volume and allowing for flexible selection based on different irrigation needs, greatly improving the practicality of irrigation operations.
