DETAILED DESCRIPTION

[0029] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only intended to enable those skilled in the art to better understand and implement the subject matter described herein. In addition, the features described relative to some examples may also be combined in other examples.

[0030] like Figure 1-Figure 8 As shown, a rotary spray gun for irrigation equipment comprises:

[0031] A manual control mechanism 1, the input and output ends of the manual control mechanism 1 are respectively connected to a hose 2 and a telescopic liquid spraying mechanism 3, the manual control mechanism 1 is used to adjust the flow rate of the liquid output from the hose 2 to the telescopic liquid spraying mechanism 3, and the telescopic liquid spraying mechanism 3 is used to spray the liquid output from the hose 2 to a set area;

[0032] The telescopic liquid spraying mechanism 3 includes a fixed sealing base assembly, a telescopic circumferential spraying assembly arranged in the fixed sealing base assembly, and a fixed-point spraying assembly connected to the other end of the telescopic spraying assembly. The fixed sealing base assembly, the telescopic circumferential spraying assembly and the fixed-point spraying assembly are all coaxially arranged. The telescopic circumferential spraying assembly is used to uniformly spray the liquid output by the hose 2 around its own radial direction, and the fixed-point spraying assembly is used to uniformly spray the liquid output by the hose 2 along its own central axis direction.

[0033] A plurality of hydraulic rotating mechanisms, the plurality of hydraulic rotating mechanisms are evenly connected inside the telescopic circumferential spraying assembly, and the plurality of hydraulic rotating mechanisms are used to drive the telescopic circumferential spraying assembly to rotate around its own central axis;

[0034] The locking mechanism 4 is used to adjust the length of the telescopic circular spraying assembly.

[0035] It should be noted that during the watering process, the manual control mechanism 1 is manually held to select a watering method according to the needs of watering the plants. One of the methods is: the locking mechanism 4 maintains a locked state, at which time the telescopic liquid spraying mechanism 3 is in the shortest state, and the channels on the telescopic circumferential spraying assembly that can spray liquid are all inside the fixed sealing base assembly. At this time, only the fixed-point spraying assembly can spray, and the hose 2 and the telescopic liquid spraying mechanism 3 are connected through the manual control mechanism 1. At this time, the liquid output by the hose 2 can only be sprayed from the fixed-point spraying assembly. In the process of water flow passing through, the telescopic circumferential spraying assembly can be driven to rotate by driving the hydraulic rotating mechanism, and the fixed-point spraying assembly can be driven to rotate in the same direction and at the same angle. At this time, the centrifugal force can expand the spraying range of the liquid sprayed from the fixed-point spraying assembly, thereby effectively increasing the spraying range;

[0036] Another way is: the locking mechanism 4 is in an unlocked state, at which time the telescopic liquid spraying mechanism 3 is in its longest state, and all the channels on the telescopic circular spraying assembly that can spray liquid are in a conducting state. At this time, the telescopic circular spraying assembly and the directional spraying assembly can simultaneously spray liquid to the outside. During the rotation process, the telescopic circular spraying assembly performs circular spraying on its coverage area, which can effectively increase the spraying range. When the telescopic circular spraying assembly is inserted into an area with dense plants such as shrubs, it can effectively improve the irrigation efficiency and reduce the consumption of water resources.

[0037] In an optional embodiment of the present invention, Figure 8As shown, the manual control mechanism 1 includes a three-way flow guide tube 101, a middle-through handle 102 detachably connected to the input end of the three-way flow guide tube 101, a hinged frame 103 connected to the outer wall of the three-way flow guide tube 101, a pressing handle 104 hinged on the hinged frame 103, a blocking member 105 connected to the pressing handle 104, a spring 107 detachably connected to the control port of the three-way flow guide tube 101, and an auxiliary sealing member connected to the inside of the three-way flow guide tube 101. 106 and a sealing cover 108 connected between a spring 107 and the plugging piece 105, the other end of the plugging piece 105 passes through the spring 107 and the sealing cover 108 in sequence and is inserted into the auxiliary sealing piece 106, the auxiliary sealing piece 106 is matched with the plugging piece 105, when a gap is generated between the plugging piece 105 and the auxiliary sealing piece 106, the input end and the output end of the three-way guide tube 101 are connected, and the hose 2 is detachably connected to the other end of the middle-through handle 102.

[0038] It should be noted that, as mentioned above, the liquid flow rate input from the hose 2 to the telescopic spray mechanism 3 is controlled by the manual control mechanism 1, specifically, by squeezing the handle 104, it is rotated around the position where it is hinged to the hinge frame 103, and drives the blocking piece 105 to move in the direction of the spring 107. As the blocking piece 105 is disengaged from the auxiliary seal 106, the internal channel of the three-way guide tube 101 is connected, and the liquid input from the hose 2 can flow out from the three-way guide tube 101. By controlling the size of the gap between the blocking piece 105 and the auxiliary seal 106, the flow rate of the liquid flowing through the manual control mechanism 1 can be controlled.

[0039] In an optional embodiment of the present invention, Figure 1-Figure 2 and Figure 5 As shown, the fixed sealing base assembly includes a fixed tube 301, a fixed ring body 3010 fixedly connected to the inner wall of the fixed tube 301, a spring 3011 connected to the fixed ring body 3010, and an annular push plate 3013 fixedly connected to the other end of the spring 3011. One end of the fixed tube 301 is detachably connected to the output end of the three-way guide tube 101, and an annular seal 3012 is provided at the opening of the other end of the fixed tube 301.

[0040] It should be noted that, as mentioned above, when the locking mechanism 4 is in an unlocked state, the spring 2 3011 inside the fixed tube 301 is no longer limited, and during its reset and extension process, it pushes the annular push plate 1 3013 connected thereto to move toward the other end of the fixed tube 301, and in this process, pushes the sliding tube 1 302 in contact with the annular push plate 1 3013 to move in the same direction and distance.

[0041] In an optional embodiment of the present invention, Figure 2 , Figure 4, Figure 6-Figure 7 As shown, the telescopic circular spray assembly includes a plurality of sliding tubes 1 302 and a sliding tube 2 303 arranged in sequence from the outside to the inside, a limiting ring body 1 3021 connected to the outer wall of one end of the sliding tube 1 302, a spring 3022 fixedly connected to the inner wall of the sliding tube 1 302, an annular push plate 2 fixedly connected to the other end of the spring 3022, a plurality of spray holes 1 3020 provided on the sliding tube 1 302, a plurality of spray holes 2 3030 provided on the sliding tube 2 303 and a limiting ring body 2 fixedly connected to the outer wall of the sliding tube 2 303, the plurality of sliding tubes 1 302 and the sliding tube 2 303 are coaxially arranged, the plurality of spray holes 1 3020 are evenly distributed on the sliding tube 1 302, and the plurality of spray holes 2 3030 are evenly distributed on the sliding tube 2 303.

[0042] The fixed-point spraying assembly includes a directional nozzle 304 connected to the output end of the second sliding tube 303 and a plurality of third spray holes 3040 arranged on the directional nozzle 304 . The directions of the third spray holes 3040 are distributed in sequence along the central axis of the second sliding tube 303 .

[0043] It should be noted that, as described above, when the locking mechanism 4 is in the unlocked state, along with the reset of the spring 2 3011 inside the fixed tube 301, the spring 3 3022 inside each sliding tube 1 302 begins to reset, and pushes the corresponding limiting ring body 2 and the corresponding sliding tube 1 302 or sliding tube 2 303 to move in the same direction and at the same distance, and with the complete reset of the spring 2 3011 and the spring 3022, all the sliding tubes 1 302 extend from the outer sliding tube 1 302 to And the sliding tube 2 303 extends out from the sliding tube 1 302, and the multiple spray holes 1 3020 and spray holes 2 3030 on the sliding tube 1 302 and the sliding tube 2 303 are all in a conductive state. At this time, water can be sprayed out from the spray holes 1 3020 and the spray holes 2 3030. As the sliding tube 1 302 and the sliding tube 2 303 rotate, the water can be sprayed along a circular rotating path, thereby forming a uniform spraying in a cylindrical area, so that irrigation can be more efficient.

[0044] In an optional embodiment of the present invention, Figure 6 As shown, the hydraulic rotating mechanism includes a connecting rod 2 501, a guide column 502 connected to the connecting rod 2 501, and a plurality of blades 503 connected to the outer wall of the guide column 502. The plurality of connecting rods 2 501 are respectively connected to a plurality of sliding tubes 1 302 and a sliding tube 2 303.

[0045] It should be noted that, as mentioned above, when water flows through the hydraulic rotating mechanism, the water flow can drive the blades 503 to rotate around the central axis of the guide column 502, and drive the guide column 502 and the connecting rod 2 501 to rotate during the rotation. The connecting rod 2 501 is connected to the corresponding sliding tube 1 302 or sliding tube 2 303, and the sliding tube 1 302 or sliding tube 2 303 can be driven by the connecting rod 2 501 to rotate in the same direction and at the same angle.

[0046] In an optional embodiment of the present invention, Figure 3 and Figure 7 As shown, the locking mechanism 4 includes a locking assembly 41 fixedly connected to the three-way flow guide pipe 101 and a movable connecting assembly 42 connected to the second sliding pipe 303 , and the movable connecting assembly 42 is detachably connected to the locking assembly 41 .

[0047] The locking assembly 41 includes a locking rod 4101 fixedly connected to the spring 107 and a threaded portion 4102 disposed at the other end of the locking rod 4101 . The length of the locking rod 4101 is greater than the length of the fixing tube 301 .

[0048] The movable connecting assembly 42 includes a fixed ring body 4201 fixedly connected to the outer wall of the sliding tube 303, a movable collar 4202 movably connected to the fixed ring body 4201, a connecting rod 4203 connected to the movable collar 4202, an annular base 4204 fixedly connected to the other end of the connecting rod 4203, and a movable nut 4205 movably connected to the annular base 4204. The annular base 4204 and the movable nut 4205 are both matched with the threaded portion 4102.

[0049] It should be noted that, as mentioned above, when the locking mechanism 4 is in a locked state, the movable nut 4205 is threadedly locked with the threaded portion 4102 on the locking rod 4101. In the absence of external rotation, the movable nut 4205 is stably connected to the locking rod 4101, and the movable nut 4205 can limit the annular base 4204, the connecting rod 1 4203, the movable collar 4202 and the fixed ring body 2 4201 at the same position. The fixed ring body 2 4201 is fixedly connected to the sliding tube 2 303, and the same limiting force can be applied to the sliding tube 2 303, thereby limiting the resetting of the multiple springs 2 3011 and the spring 3022. When in the contact locked state, the movable nut 4205 can be unscrewed from the threaded portion 4102 on the locking rod 4101.

[0050] In an optional embodiment of the present invention, the connecting rod 4203 includes a hollow sleeve fixedly connected to the movable ring 4202 and a threaded rod threadedly connected to the hollow sleeve, the movable ring 4202 is provided with a through hole matching the hollow sleeve, the length of the threaded rod is greater than the length of the hollow sleeve, and the annular base 4204 is fixedly connected to the threaded rod.

[0052] The present embodiment is described above, but the present embodiment is not limited to the above-mentioned specific implementation manner. The above-mentioned specific implementation manner is merely illustrative and not restrictive.
