The stabilizing plate and the mounting plate 11 are both rotatably connected to the end of the electric push rod 12, and the outer wall of the hollow rotating rod 14 is staggered with a plurality of symmetrical through holes 22, a rotating mechanism is arranged between the two hollow rotating rods 14, and an adjusting mechanism is arranged in the rotating mechanism, the top of the hollow rotating rod 14 is sealed and rotatably connected to a rotating joint 24, a water pump 10 is arranged on the outer wall of the top of the water storage tank 2, and the output end of the water pump 10 is connected to a three-way pipe 9, and both ends of the three-way pipe 9 are connected to a telescopic pipe 8, and the telescopic pipe 8 is connected to the corresponding rotating joint 24, when it is necessary to irrigate the forest vegetation , move the vehicle body 1 to the side of the vegetation, and according to the size of the vegetation, start the electric push rods 12 on both sides of the lifting plate 4 to adjust the distance between the two mounting plates 11. At the same time, the adjustment mechanism will run at the same time to ensure that the driving mechanism can rotate the hollow rotating rod 14, and then push the vehicle body 1 close to the vegetation so that the watered vegetation is between the two mounting plates 11, and then start the rotating motor 7, which drives the threaded rod 5 connected to it to rotate, so that the threaded slider 6 on the surface of the threaded rod 5 moves the lifting plate 4 downward, and at the same time, the driving mechanism runs so that the two mounting plates 11 are connected. The hollow rotating rods 14 on the mounting plate 11 rotate so that the two hollow rotating rods 14 can be inserted into the soil where the vegetation is planted, and then the water pump 10 in the water tank 2 is started. The water pump 10 pumps out the water in the water tank 2 and transports it to the three-way pipe 9. Finally, the water is input into the corresponding hollow rotating rods 14 through the telescopic tubes 8 at both ends of the three-way pipe 9, so that the water is sprayed out through the multiple through holes 22 on the hollow rotating rods 14, which can moisten the soil around the roots of the vegetation, thereby irrigating the roots of the forestry vegetation, so that the water is fully absorbed by the roots of the forestry vegetation, and precise irrigation is performed to avoid wasting water resources.

[0030] As a further solution in the present invention, the rotating mechanism includes a rotating motor 20, a mounting opening 13 is provided in the middle of the top of the lifting plate 4, the rotating motor 20 is embedded in the mounting opening 13, and two pulleys 19 are fixedly connected to the output shaft end of the rotating motor 20. When the rotating motor 20 is started, it can drive the two pulleys 19 at its output shaft end to rotate.

[0031] As a further solution in the present invention, a rotating shaft 25 is provided on one side of the hollow rotating rod 14, and a gear 26 is fixedly connected to the bottom end of the rotating shaft 25, a gear 23 is meshed with one side of the gear 26, and the gear 23 is fixedly connected to the outer wall of the hollow rotating rod 14, and a pulley 15 is fixedly connected to the top of the rotating shaft 25, and a belt 21 is provided on the outer wall of the pulley 15 and the corresponding pulley 2 19. Through the transmission of the belt 21, the rotating shaft 25 can rotate with the gear 26, because the gear 26 is meshed with the gear 23 on the outer wall of the hollow rotating rod 14, the hollow rotating rod 14 is rotated.

[0032] As a further solution in the present invention, the adjustment mechanism includes two electric push rods 17, which are respectively fixedly connected to the top outer walls of the corresponding mounting plates 11, and the telescopic ends of the electric push rods 17 are fixedly connected to the fixed blocks 16, and the top outer walls of the fixed blocks 16 are provided with rollers 18, and the rollers 18 are in contact with the corresponding inner walls of the belts 21 and keep them in a taut state. The position of the rollers 18 on the fixed blocks 16 can be adjusted by the electric push rods 17. When the distance between the two mounting plates 11 is adjusted, the electric push rods 17 will be started at the same time, so that the belt 21 is always in a taut state, ensuring the transmission effect of the pulley 15, the belt 21 and the pulley 2 19.

[0033] Working principle: when it is necessary to water the forest vegetation, the vehicle body 1 is moved to the side of the vegetation, and according to the size of the vegetation, the electric push rods 12 on both sides of the lifting plate 4 are started to adjust the distance between the two mounting plates 11. At the same time, when the distance between the two mounting plates 11 is adjusted, the electric push rod 2 17 will be started at the same time, and the position of the roller 18 on the fixed block 16 can be adjusted by the electric push rod 2 17, so that the belt 21 is always in a taut state to ensure the transmission effect of the pulley 15, the belt 21 and the pulley 2 19, and then the vehicle body 1 is pushed close to the vegetation so that the watered vegetation is between the two mounting plates 11, and then the rotating motor 1 7 is started. The rotating motor 1 7 drives the threaded rod 5 connected to it to rotate, so that the threaded slider 6 on the surface of the threaded rod 5 moves the lifting plate 4 downward, and at the same time, the rotating motor 20 can drive its transmission when it is started. The two pulleys 19 at the shaft end rotate, and the belt 21 sleeved on the outer wall of the pulley 15 and the corresponding pulley 19 can make the rotating shaft 25 rotate with the gear 26. Because the gear 26 is meshed with the gear 23 on the outer wall of the hollow rotating rod 14, the hollow rotating rod 14 is rotated, and the hollow rotating rods 14 on the two mounting plates 11 are rotated, so that the two hollow rotating rods 14 can be inserted into the soil where the vegetation is planted, and then the water pump 10 in the water tank 2 is started, and the water pump 10 draws out the water in the water tank 2 and transports it to the three-way pipe 9. Finally, it is input into the corresponding hollow rotating rod 14 through the telescopic tubes 8 at both ends of the three-way pipe 9, so that the water is sprayed out through the multiple through holes 22 on the hollow rotating rod 14, which can moisten the soil around the root system of the vegetation, thereby irrigating the root system of the forestry vegetation, so that the water is fully absorbed by the root system of the forestry vegetation, and precise irrigation is performed to avoid wasting water resources.

[0034] Example 2, reference Figure 1-Figure 6 , a forestry irrigation device, compared with embodiment 1, on the basis of embodiment 1, two L-shaped plates 29 are arranged between symmetrical through holes 1 22, and the two L-shaped plates 29 are fixedly connected to the inner wall of the hollow rotating rod 14, the lower parts of the two L-shaped plates 29 are rotatably connected to the same rotating shaft 27, and a plurality of pushing plates 28 are fixedly connected to the outer wall of the middle part of the rotating shaft 27 at equal distances, and the outer walls of the L-shaped plates 29 are all provided with through openings 30. When water is input into the hollow rotating rod 14, the water will flow from the top of the hollow rotating rod 14 to the bottom of the hollow rotating rod 14, and finally be sprayed out through each through hole 1 22. During the flow of water, each rotating shaft 27 can be rotated by pushing the plate 28.

[0035] As a further solution in the present invention, both ends of the rotating shaft 27 extend into the corresponding through hole 1 22, and a plurality of triangular blocks 31 are evenly and fixedly connected to the outer walls of both ends of the rotating shaft 27, the sharp ends of the triangular blocks 31 face the interior of the hollow rotating rod 14, and a plurality of water diversion grooves 33 are evenly spaced on the outer walls of the triangular blocks 31, and a plurality of vertical openings 32 are opened inside the water diversion grooves 33. When the rotating shaft 27 rotates, the plurality of triangular blocks 31 in each through hole 1 22 will rotate. Because the sharp ends of the triangular blocks 31 face the interior of the hollow rotating rod 14, the water sprayed out of the through hole 1 22 can be divided and scattered into multiple strands, and through the vertical openings 32 of each water diversion groove 33, the water can be divided and scattered again to splash out, thereby greatly increasing the spraying range of water in the soil, thereby greatly increasing the range of soil moistening, so that more roots of vegetation can absorb water.

[0036] Working principle: When water is input into the hollow rotating rod 14, the water will flow from the top of the hollow rotating rod 14 to the bottom of the hollow rotating rod 14, and finally spray out through each through hole 1 22. During the flow of water, the push plate 28 can make each rotating shaft 27 rotate. When the rotating shaft 27 rotates, the multiple triangular blocks 31 in each through hole 1 22 will rotate. Because the sharp end of the triangular block 31 faces the inside of the hollow rotating rod 14, the water sprayed out of the through hole 1 22 can be divided and scattered into multiple strands, and through the vertical openings 32 of each water diversion trough 33, the water can be divided and scattered again to splash out, greatly increasing the spraying range of water in the soil, thereby greatly increasing the range of soil moistening, so that more roots of vegetation can absorb water.

[0037] Example 3, reference Figure 1-Figure 8 , a forestry irrigation device, compared with embodiment 2, on the basis of embodiment 2, a circular cavity 34 is provided inside the hollow rotating rod 14, and the inner wall of the circular cavity 34 is sealed and slidably connected with a sealing cylinder 35, an electromagnet 39 is provided on the inner wall of the top of the circular cavity 34, a plurality of magnetic plates 37 are fixedly connected to the outer wall of the top of the sealing cylinder 35, and a plurality of connecting springs 38 are fixedly connected between the magnetic plate 37 and the electromagnet 39, and the magnetic force generated by the electromagnet 39 after being energized repels the magnetic plate 37.

[0038] As a further solution in the present invention, a plurality of through holes 36 are provided on the outer wall of the sealing cylinder 35, and the through holes 36 correspond one-to-one with the through holes 22. When the electromagnet 39 is not energized, the through holes 36 on the sealing cylinder 35 are misaligned with the through hole 22, thereby sealing the through hole 22. When the electromagnet 39 is energized, the sealing cylinder 35 moves downward so that the through holes 36 on its outer wall are aligned with the through hole 22, so that the through hole 22 is no longer sealed, allowing water to spray out through the through hole 22.

[0039] Working principle: when the electromagnet 39 is energized, the magnetic force generated by the electromagnet 39 repels the magnetic plate 37, so that the repulsive force will stretch the sealing tube 35 and the multiple connecting springs 38 will move downward, so that the through hole 2 36 on the outer wall of the sealing tube 35 is aligned with the through hole 1 22, so that the through hole 1 22 is no longer sealed, so that water can be sprayed out through the through hole 1 22, and when the electromagnet 39 is not energized, the electromagnet 39 will not generate a magnetic force that repels the magnetic plate 37, so that the sealing tube 35 is reset under the action of the rebound force of the multiple connecting springs 38, and after the reset, the through hole 2 36 on the sealing tube 35 is misaligned with the through hole 1 22, thereby sealing the through hole 1 22, which can prevent soil from entering the hollow rotating rod 14 through the through hole 1 22 and causing blockage.
