[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-Figure 5 A sprinkler for fixed-point irrigation of crops provided in this embodiment includes a bracket 1, a screw rod 2 is arranged on the bracket 1, a handle 3 is arranged on the top of the screw rod 2, a slide seat 4 located inside the bracket 1 is arranged on the screw rod 2, a nozzle 6 is arranged on the slide seat 4 through a fixing frame 5, and a connecting hose 7 is fixedly connected to the nozzle 6, an insertion rod 9 is arranged at the bottom of the bracket 1 through a bottom plate 8, and a positioning component 10 for limiting the rotation of the screw rod 2 is arranged on the bracket 1.

[0026] In the utility model, when installing the sprinkler, the bracket 1 is plugged and fixed to the irrigation site by using the plug rod 9 at the bottom of the base plate 8, and then the connecting hose 7 on the nozzle 6 is connected to the water supply pipe, so that the irrigation water in the water supply pipe can be sent to the nozzle 6 for sprinkler irrigation through the connecting hose 7. During the irrigation process, if it is necessary to adjust the height of the nozzle 6 according to the terrain or the irrigation needs of the crops, the positioning component 10 can be opened first, and then the screw 2 on the bracket 1 can be screwed by the handle 3. When the screw 2 rotates, the slide 4 matched with its thread will move linearly on the screw 2, so that the slide 4 can be used to drive the nozzle 6 on the fixing frame 5 to move. After the movement is completed, the screw 2 can be fixed by using the positioning component 10 to achieve the adjustment of the height position of the nozzle 6, which can more accurately meet the irrigation needs of different crops, make the irrigation more uniform, and improve the irrigation efficiency.

[0027] Specifically, Figure 1-Figure 3 As shown, the positioning assembly 10 includes a latch 104 on which a limiting plate 105 is disposed. A positioning plate 31 is fixedly connected to the screw rod 2 at the top of the bracket 1 , and a positioning hole 32 matching the latch 104 is formed on the positioning plate 31 .

[0028] When the height of the nozzle 6 needs to be adjusted, the latch 104 is first pulled out from the positioning hole 32 of the positioning plate 31, and then the screw 2 can be rotated by the handle 3 to move the slide 4 to drive the nozzle 6 to adjust its height. After the adjustment, the latch 104 can be inserted into the positioning hole 32. A fixing hole with the same diameter as the positioning hole 32 is provided on the top of the bracket 1. The latch 104 passes through the positioning hole 32 and is inserted into the fixing hole of the bracket 1, so that the positioning plate 31 is fixed to the bracket 1, thereby ensuring that the screw 2 will not rotate and cause the nozzle 6 to loosen during daily use.

[0029] It should be noted that there are a plurality of positioning holes 32 arranged in a circular array on the positioning plate 31. After the screw 2 rotates, the plurality of positioning holes 32 can accurately locate the positioning hole 32 that matches the fixing hole on the bracket 1, so that after the height of the nozzle 6 is adjusted, the positioning hole 32 on the positioning plate 31 coincides with the fixing hole of the bracket 1, ensuring that the latch 104 can relatively fix the positioning plate 31 and the bracket 1.

[0030] Specifically, Figure 2 and Figure 3 As shown, a connecting rope 102 is provided on the latch pin 104 via a lifting ring 103 , and one end of the connecting rope 102 away from the lifting ring 103 is connected to the bracket 1 via a fixing block 101 .

[0031] The latch 104 is suspended on the bracket 1 by the connecting rope 102 on the fixing block 101 , so that when the latch 104 needs to be pulled out to adjust the height of the nozzle 6 , the latch 104 can be prevented from being lost, thus facilitating the operation.

[0032] It should be noted that the bracket 1 is provided with a slide rail 11, and the slide seat 4 is provided with a slide groove 41 that matches the slide rail 11. The slide rail 11 and the slide groove 41 play a guiding role, ensuring the accurate movement of the slide seat 4 on the screw rod 2, and reducing the friction between the slide seat 4 and the bracket 1, thereby extending the service life of the slide seat 4.

[0033] Specifically, Figure 1 and Figure 4 As shown, the nozzle 6 is movably connected to the fixing frame 5 via a shaft 61 , and the fixing frame 5 is provided with an adjusting bolt 51 for adjusting the angle between the nozzle 6 and the fixing frame 5 .

[0034] Among them, the nozzle 6 can be rotated on the fixing frame 5 through the shaft rod 61. When the adjusting bolt 51 is loosened, the clamping force of the fixing frame 5 on the nozzle 6 becomes smaller. At this time, the nozzle 6 can be rotated through the shaft rod 61 to adjust the angle of the nozzle 6, so that it can adapt to the angle adjustment needs of different crops. After the angle is adjusted, tighten the adjusting bolt 51 to increase the clamping force of the fixing frame 5 on the nozzle 6, thereby clamping and fixing the nozzle 6 to ensure the stability of the nozzle 6 during sprinkler irrigation.

[0035] Specifically, Figure 1 and Figure 5 As shown, the insertion rod 9 includes a connecting section 91 connected to the base plate 8, and the bottom of the connecting section 91 is sequentially connected with a first insertion section 92, a second insertion section 93 and a plug 94, and the first insertion section 92, the second insertion section 93 and the plug 94 form a tower structure.

[0036] Among them, the tower-like structure formed by the first insertion section 92, the second insertion section 93 and the plug 94 can make the bracket 1 more stable after being inserted into the soil, which helps to reduce the displacement or damage of the nozzle caused by factors such as wind and vibration. The plug 94 is conical, which can reduce the resistance when inserted into the soil, so that the insertion rod 9 can fix the bracket 1 more easily and stably, thereby ensuring the stability of the nozzle 6 on the bracket 1.

[0037] It should be noted that a threaded end 95 penetrating the bottom plate 8 is provided at the top of the connecting section 91 , and a locking nut 96 abutting against the bottom plate 8 is provided on the threaded end 95 .

[0038] Among them, after the locking nut 96 on the threaded end 95 is removed, the plug rod 9 can be pulled out from the base plate 8, realizing a detachable connection between the plug rod 9 and the base plate 8, thereby facilitating the maintenance and repair of the plug rod 9 and ensuring that the plug rod 9 can realize effective plug-in installation of the bracket 1.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
