[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figure 1-6 The present invention provides the following technical solution: a root drip irrigation device for forestry irrigation, including a drip irrigation pipe 1, an installation plate 6 at the upper end of the drip irrigation pipe 1, a tapered part 3 at the lower end of the drip irrigation pipe 1, multiple sets of drip irrigation holes 2 on the side of the drip irrigation pipe 1, a fixing nail 7 at the lower side of the installation plate 6, a drip irrigation mechanism 5 inside the drip irrigation pipe 1, and a drip irrigation liquid injection mechanism 4 at the upper side of the installation plate 6.

[0025] Specifically, the drip irrigation mechanism 5 includes a hollow screw 51, a piston rod positioning assembly 52, a piston rod 53, a push handle 54, a knob 55, a first piston plate 56, and a second piston plate 57. The hollow screw 51 is internally threaded onto the mounting plate 6. The second piston plate 57 is located at the lower end of the hollow screw 51, and the knob 55 is located at the upper end of the hollow screw 51. The piston rod 53 is internally slidably connected to the hollow screw 51, the second piston plate 57, and the knob 55. The push handle 54 is located at the upper end of the piston rod 53, the first piston plate 56 is located at the lower end of the piston rod 53, and the piston rod positioning assembly 52 is located on the upper side of the knob 55.

[0026] By adopting the above technical solution, when drip irrigating the plant roots, the tapered part 3 at the lower end of the drip irrigation pipe 1 is inserted into the plant roots, and the fixing nail 7 at the lower end of the mounting plate 6 is inserted into the roots. Then, the knob 55 is turned, which drives the hollow screw 51 to rotate. The rotation of the hollow screw 51 drives the piston plate 57 to descend to the appropriate position. Then, the push handle 54 is pressed, which drives the piston rod 53 to descend, thereby driving the piston plate 56 to descend, so that the drip irrigation liquid in the drip irrigation pipe 1 is discharged through the drip irrigation hole 2 and injected into the plant roots.

[0027] Specifically, the piston rod positioning assembly 52 includes anti-slip texture 521, an arc-shaped plate 522, a spring 523, a pull rod 524, a handle 525, and a mounting ring 526. The upper side of the knob 55 is provided with the mounting ring 526, and the pull rod 524 passes through the side of the mounting ring 526. One end of the pull rod 524 is provided with the handle 525, and the other end of the pull rod 524 is provided with the arc-shaped plate 522. The side of the arc-shaped plate 522 is provided with anti-slip texture 521. A spring 523 is fitted onto the surface of the pull rod 524 at the position between the arc-shaped plate 522 and the mounting ring 526.

[0028] By adopting the above technical solution, when the piston rod 53 is slidable, the handle 525 is pulled, the handle 525 pulls the lever 524, the lever 524 pulls the arc plate 522 and causes the spring 523 to compress. At this time, the piston rod 53 can slide smoothly. After adjustment, the handle 525 is released, the spring 523 rebounds, thereby causing the arc plate 522 to fix the piston rod 53. Through the anti-slip texture 521 on the side of the arc plate 522, the piston rod 53 can be positioned by the action of friction.

[0029] Specifically, the drip irrigation holes 2 are arranged inside the drip irrigation pipe 1 in an order of increasing size, with the smaller end of the drip irrigation hole 2 located on the inner side of the drip irrigation pipe 1.

[0030] By adopting the above technical solution and setting the drip irrigation holes 2 from small to large, the problem of drip irrigation liquid flowing out can be avoided. The drip irrigation liquid will only flow out when the internal pressure of the drip irrigation pipe 1 is high.

[0031] In this embodiment, when drip irrigating plant roots, the tapered portion 3 at the lower end of the drip irrigation tube 1 is inserted into the plant roots, and the fixing nail 7 at the lower end of the mounting plate 6 is inserted into the roots. Then, the knob 55 is turned, which drives the hollow screw 51 to rotate. The rotation of the hollow screw 51 causes the piston plate 57 to descend to a suitable position. Then, the push handle 54 is pressed, which drives the piston rod 53 to descend, thereby causing the piston plate 56 to descend, thus discharging the irrigation solution in the drip irrigation tube 1 through the drip irrigation hole 2 and injecting it into the plant roots. When sliding the piston rod 53, the pull handle 525 is pulled. Pulling handle 525 moves lever 524, lever 524 moves arc plate 522 and compresses spring 523, allowing piston rod 53 to slide smoothly. After adjustment, release pull handle 525, spring 523 rebounds, thereby moving arc plate 522 to fix piston rod 53. The anti-slip texture 521 on the side of arc plate 522 can position piston rod 53 through friction. By setting drip holes 2 from small to large, the problem of drip liquid flowing out can be avoided. Drip liquid will only flow out when the internal pressure of drip tube 1 is high.

[0032] Example 2

[0033] The difference between this embodiment and Embodiment 1 is that the drip irrigation fluid injection mechanism 4 includes a valve 41, a filling funnel 42, an inlet groove 43, a guide assembly 44, an inlet hole 45, and an inlet pipe 46. An inlet groove 43 is provided inside the side of the drip irrigation pipe 1, and an inlet hole 45 is provided at the lower end of the side of the inlet groove 43. An inlet pipe 46 is provided on the upper side of the mounting plate 6, and a filling funnel 42 is provided at the upper end of the inlet pipe 46. A valve 41 is provided on the side of the inlet pipe 46, and a guide assembly 44 is provided on the inner wall of the drip irrigation pipe 1.

[0034] By adopting the above technical solution, valve 41 is opened, and the drip irrigation liquid is poured into the inside of the inlet pipe 46 through the filling funnel 42, so that the drip irrigation liquid flows into the inside of the drip irrigation pipe 1 along the inlet groove 43 and the inlet hole 45, so as to carry out subsequent root drip irrigation work.

[0035] Specifically, the guide assembly 44 includes an arc-shaped protrusion 441 and an arc-shaped groove 442. The inner wall of the drip irrigation tube 1 is provided with an arc-shaped protrusion 441, and the sides of the piston plate 56 and piston plate 57 are provided with arc-shaped grooves 442 corresponding to the arc-shaped protrusion 441.

[0036] By adopting the above technical solution, when piston plate 1 56 and piston plate 2 57 rise and fall, the arc-shaped protrusion 441 will slide inside the arc-shaped groove 442, thereby improving the stability of the sliding process in piston plate 1 56 and piston plate 2 57.

[0037] In this embodiment, when in use, valve 41 is opened, and the drip irrigation liquid is poured into the inside of the inlet pipe 46 through the filling funnel 42, so that the drip irrigation liquid flows into the inside of the drip irrigation pipe 1 along the inlet groove 43 and the inlet hole 45, so as to carry out subsequent root drip irrigation work. When piston plate 1 56 and piston plate 2 57 rise and fall, the arc-shaped protrusion 441 slides inside the arc-shaped groove 442, thereby improving the stability of the sliding process of piston plate 1 56 and piston plate 2 57.

[0038] The working principle and usage process of this utility model are as follows: When using this utility model for drip irrigation of plant roots, insert the tapered part 3 at the lower end of the drip irrigation tube 1 into the plant root, insert the fixing nail 7 at the lower end of the mounting plate 6 into the root, and then turn the knob 55. The rotation of the knob 55 drives the hollow screw 51 to rotate, which in turn drives the piston plate 57 to descend to the appropriate position. Then press the push handle 54, which drives the piston rod 53 to descend, thereby driving the piston plate 56 to descend, thus discharging the drip irrigation liquid in the drip irrigation tube 1 through the drip irrigation hole 2 and injecting it into the plant root. When the piston rod 53 is sliding, pull the pull handle 525. The pull handle 525 pulls the pull rod 524, which pulls the arc plate 522 and causes the spring 523 to compress. At this time, the piston rod 53 can slide smoothly. After adjustment, release the knob. Pulling handle 525 causes spring 523 to return, thereby driving arc plate 522 to fix piston rod 53. The anti-slip texture 521 on the side of arc plate 522 can position piston rod 53 through friction. By setting the drip irrigation holes 2 from small to large, the problem of drip irrigation liquid flowing out can be avoided. Drip irrigation liquid will only flow out when the internal pressure of drip irrigation tube 1 is high. Opening valve 41 allows drip irrigation liquid to be poured into the inside of inlet pipe 46 through filling funnel 42, so that drip irrigation liquid flows into the inside of drip irrigation tube 1 along inlet groove 43 and inlet hole 45 for subsequent root drip irrigation. When piston plate one 56 and piston plate two 57 rise and fall, the arc protrusion 441 slides inside the arc groove 442, thereby improving the stability of the sliding process of piston plate one 56 and piston plate two 57.
