TECHNICAL FIELD

[0001] The application relates to the technical field of irrigation sprinklers, in particular to an adjustable sprinkler device for irrigation. BACKGROUND

[0002] In the field of agricultural irrigation, irrigation sprinklers are key equipment, and their performance directly affects the irrigation effect and the growth of crops. However, existing irrigation sprinklers have a series of problems. On the one hand, the irrigation position and area of most sprinklers are fixed, which is difficult to adapt to different planting patterns of crops and complex terrains such as uneven mountainous areas or irregularly shaped farmlands, resulting in insufficient or excessive irrigation in some areas and serious waste of water resources. On the other hand, the installation and maintenance process of the sprinkler is usually complex, requiring professional personnel and tools, consuming a lot of time and effort, and increasing the cost of agricultural production. In addition, many sprinklers are inconvenient to operate, requiring operators to have certain professional skills, which poses a certain difficulty for ordinary farmers. At the same time, the irrigation mode of traditional sprinklers is prone to uneven irrigation, and local areas may appear waterlogging or drought, affecting the overall growth and yield of crops.

[0003] Therefore, it is of great practical significance to develop an adjustable sprinkler device for irrigation that can flexibly adjust the irrigation position and area, is convenient to install and maintain, is easy to operate, and irrigates uniformly. SUMMARY

[0004] In view of the above technical problems, the application solves the problems of limited irrigation position and area, inconvenient sprinkler maintenance, and poor irrigation uniformity in the prior art.

[0005] In order to achieve the above purpose, the technical scheme adopted by the application is as follows: an adjustable sprinkler device for irrigation, comprising a threaded pipe, an inner pipe is fixedly arranged on the threaded pipe, a stop ring is fixedly arranged at the end of the threaded pipe in contact with the inner pipe, a clamping ring is fixedly arranged on the threaded pipe, the cross section of the clamping ring is triangular, a rotating drum is movably arranged on the inner pipe, a limiting ring is fixedly arranged on the side of the rotating drum close to the inner pipe, a plurality of clamping blocks are fixedly arranged on the rotating drum, the clamping blocks are in the shape of an upside-down number 7, and the clamping blocks are elastic, a plurality of grooves for spraying water are arranged at the end of the rotating drum away from the threaded pipe, the inclination angles of the grooves are different, a plurality of threaded segments are arranged on the side of the rotating drum close to the inner pipe, the threaded segments avoid the groove positions on the rotating drum, an arc-shaped top plate is threadedly connected to the threaded segments, and a fan ring is fixedly connected to the side of the rotating drum close to the inner pipe.

[0006] Preferably, the rotating drum is provided with four grooves, and the inclination angles are 70-120 degrees.

[0007] Preferably, the arc-shaped top plate is fixedly provided with an inner rotating ring, a plurality of threaded pieces are fixedly arranged on the inner rotating ring, and threads are arranged on the threaded pieces.

[0008] Preferably, the inner rotating ring is fixedly provided with a contact rod for contacting hands and limiting movement of the arc-shaped top plate, and the rotating cylinder is fixedly provided with an anti-skid strip.

[0009] Preferably, the inner tube is fixedly provided with a limiting vertical rod, a limiting horizontal rod is slidably arranged on the limiting vertical rod, a main shaft is rotatably arranged on the limiting horizontal rod, and an end of the main shaft away from the limiting horizontal rod is rotatably connected with the arc-shaped top plate.

[0010] Preferably, the fan ring comprises a rotating ring and a plurality of fan blades, and the arc-shaped top plate comprises an arc-shaped cover and a connecting ring.

[0011] Compared with the prior art, the technical scheme provided in the application has the following beneficial effects:

[0012] 1. The application can accurately control the number of grooves with different inclination angles on the rotating cylinder by rotating the position of the arc-shaped top plate on the threaded segment of the rotating cylinder, thereby realizing irrigation at different positions. For example, the 70-degree groove can spray water farther to the upper side for irrigation at a distance, and the 90-degree-120-degree groove can spray water with a gradually decreasing distance, thereby meeting the irrigation needs of different areas of various agricultural plantings and expanding the irrigation area. This flexible adjustment function can adapt to different crop planting layouts and terrain conditions and improve the utilization efficiency of irrigation water.

[0013] 2. The rotating cylinder is installed through the ingenious cooperation of the clamping block and the clasp. When installed, the clamping block is bent by being pressed by the inclined surface of the clasp, and is automatically reset to form a limit after being bent, thereby limiting the up-down movement of the rotating cylinder. When disassembled, the clamping block can be bent manually to release the limit, thereby facilitating the maintenance and other operations of the rotating cylinder and reducing the difficulty and cost of equipment maintenance.

[0014] 3. The staff of the application only needs to operate with one hand, holds the anti-skid strip of the rotating cylinder with the thumb and middle finger, and presses the contact rod with the index finger, so as to easily limit the rotation of the arc-shaped top plate and control the rotation of the rotating cylinder to adjust the height of the arc-shaped top plate. The operation is simple and convenient, and the labor intensity of the operator is reduced.

[0015] 4. The water source impact fan ring drives the rotating cylinder and the arc-shaped top plate to rotate, so that the groove on the rotating cylinder rotates while spraying water, the sprayed water rotates around the threaded pipe axis, and circular coverage irrigation is realized, thereby avoiding the problems of local water accumulation or uneven irrigation caused by fixed-point long-time irrigation, and being beneficial to the uniform growth of crops.

[0016] 5. The setting of the limiting vertical rod, the limiting horizontal rod and the main shaft not only limits the movement direction of the arc-shaped top plate, ensures that it can only move up and down, but also limits the movement distance through the conversion contact of the limiting horizontal rod and the fan ring, so that the whole adjustment process is stable and reliable, and ensures the accurate realization of the irrigation adjustment function.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application.

[0025] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0026] As Figures 1 to 6As shown, an adjustable irrigation nozzle device includes a threaded pipe 101, an inner pipe 103 fixedly arranged on the threaded pipe 101, a retaining ring 102 fixedly arranged on the threaded pipe 101 in contact with the inner pipe 103, the outer diameter of the retaining ring 102 being larger than the outer diameter of the threaded pipe 101, a snap ring 104 fixedly arranged on the threaded pipe 101, the cross section of the snap ring 104 being triangular, one of the two right angle sides of the snap ring 104 being in contact with the threaded pipe 101 and the other being towards the side of the threaded pipe 101, a rotating drum 106 movably arranged on the inner pipe 103, a limiting ring 108 fixedly arranged on the side of the rotating drum 106 close to the inner pipe 103, a plurality of clamping blocks 105 fixedly arranged on the rotating drum 106, the clamping blocks 105 being in the shape of upside-down number 7 and having elasticity, a plurality of grooves for spraying water being arranged on the end of the rotating drum 106 away from the threaded pipe 101, the grooves having different inclination angles, a plurality of threaded segments being arranged on the side of the rotating drum 106 close to the inner pipe 103, the threaded segments being away from the positions of the grooves on the rotating drum 106, an arc-shaped top plate 110 threadedly connected on the threaded segments, and a fan-shaped ring 109 fixedly connected on the side of the rotating drum 106 close to the inner pipe 103.

[0027] Specifically, the device is arranged on a water pipe through the threaded pipe 101, then according to the irrigation requirement, the arc-shaped top plate 110 is controlled to rotate on the threaded segments inside the rotating drum 106, so as to change the horizontal height of the arc-shaped top plate 110, so that the arc-shaped top plate 110 moves to the grooves of the rotating drum 106, the number of the grooves of the rotating drum 106 used is selected according to the moving position of the arc-shaped top plate 110, that is, after the arc-shaped top plate 110 moves above a groove, the groove contacts the water source and the water source can be sprayed from the groove, and according to the setting of the groove angle, the spraying position is also different, so that irrigation of different positions is realized, and the irrigation requirement of various agricultural planting is adapted.

[0028] When the rotating drum 106 is installed, the end of the rotating drum 106 close to the clamping block 105 is directed towards the threaded pipe 101, so that the upper end of the inner pipe 103 is inserted, and the rotating drum 106 is slid downwards on the inner pipe 103, and the rotating drum 106 is continuously pushed downwards, so that the clamping block 105 on the rotating drum 106 is in contact with the clamping ring 104, and the clamping block 105 is bent by the slope on the clamping ring 104, and the rotating drum 106 is continuously pushed, and after the clamping block 105 passes the clamping ring 104, the clamping block 105 no longer receives the pushing force of the slope on the clamping ring 104, and the clamping block 105 is reset under the elastic force of the clamping block 105 itself, and the end of the clamping block 105 close to the threaded pipe 101 moves to the inside of the outer diameter of the clamping ring 104, that is, the clamping ring 104 and the end of the clamping block 105 close to the threaded pipe 101 form a limit, which limits the upward movement of the clamping block 105 and the rotating drum 106 on the inner pipe 103, and the limiting ring 108 inside the rotating drum 106 is in contact with the upper end of the threaded pipe 101 when the clamping block 105 is reset, thereby supporting the rotating drum 106 and limiting the downward movement of the rotating drum 106, so that the rotating drum 106 cannot move upwards or downwards at this time. When it is necessary to disassemble the rotating drum 106, the worker manually controls the bending of the clamping block 105, so that the inwardly protruding block at the lower end of the clamping block 105 moves to the outside of the outer diameter of the clamping ring 104, thereby contacting the limit formed by the clamping block 105 and the clamping ring 104, and the rotating drum 106 can be moved upwards and removed, and then maintenance and other work can be performed. The convenient installation and disassembly structure of the clamping block 105 and the clamping ring 104 makes the disassembly and installation of the rotating drum easy to realize, and facilitates the inspection, maintenance and replacement of parts inside the nozzle.

[0029] As shown in Figure 2 , four grooves are arranged on the rotating drum 106, and the inclination angles are 70 degrees-120 degrees. Specifically, the four grooves are 70 degrees, 90 degrees, arc-shaped top plate 110 degrees and 120 degrees from top to bottom. The 70-degree groove sprays upward and to the side to increase the distance of water spraying, which is used for irrigation at a distance, and the distance of water spraying decreases from 90 degrees to 120 degrees.

[0030] As shown in Figure 3 , the inner rotating ring 111 is fixedly arranged on the arc-shaped top plate 110, a plurality of threaded pieces 113 are fixedly arranged on the inner rotating ring 111, threads are arranged on the threaded pieces 113, and the threads of the threaded pieces 113 are matched with the threaded segments on the side of the rotating drum 106 close to the inner pipe 103.

[0031] As shown in Figure 3 , the contact rod 112 is fixedly arranged on the inner rotating ring 111, which is used for contacting the hand and limiting the movement of the arc-shaped top plate 110, and the anti-skid strip 107 is fixedly arranged on the rotating drum 106.

[0032] Specifically, when the horizontal height of the arc-shaped top plate 110 needs to be adjusted, the worker only needs to use one hand to operate, that is, the thumb and middle finger fall on the anti-skid strip 107 of the rotating drum 106, the index finger falls on the contact rod 112, and then the index finger is pressed against the contact rod 112, thereby limiting the arc-shaped top plate 110 through the inner rotating ring 111 to avoid the arc-shaped top plate 110 from following the rotating drum 106 to rotate subsequently, and then the rotating drum 106 is controlled to rotate on the threaded pipe 101 through the thumb and middle finger, the inner tube 103 supports the limiting ring 108 and the rotating drum 106 through the contact between the limiting ring 108 and the upper end opening of the inner tube 103, and the clamping block 105 limits the upward movement of the rotating drum 106, so that the rotating drum 106 can rotate on the inner tube 103, the threaded segment in the rotating drum 106 drives the threaded piece 113 to move upward due to the threaded cooperation with the threaded piece 113, the threaded piece 113 drives the contact rod 112 and the arc-shaped top plate 110 to move upward through the inner rotating ring 111, so that the arc-shaped top plate 110 moves to the groove of the rotating drum 106, and the release of different numbers of grooves is realized by the movable height of the arc-shaped top plate 110, so that water can be sprayed out, thereby realizing long-distance irrigation and expanding the irrigation area.

[0033] As shown in Figure 2 and Figure 6 , the inner tube 103 is fixedly provided with a limiting vertical rod 116, the limiting vertical rod 116 is slidably provided with a limiting horizontal rod 115, and the limiting horizontal rod 115 is rotatably provided with a main shaft 114, and the end of the main shaft 114 away from the limiting horizontal rod 115 is rotatably connected with the arc-shaped top plate 110.

[0034] Specifically, when the arc-shaped top plate 110 moves upward, the arc-shaped top plate 110 drives the main shaft 114, the protrusion at the lower end of the main shaft 114 drives the limiting horizontal rod 115 to slide upward on the inner wall of the limiting vertical rod 116 and the threaded pipe 101, the movement distance of the limiting horizontal rod 115 is limited through the conversion contact between the limiting horizontal rod 115 and the fan ring 109, and the movement direction of the limiting horizontal rod 115 is limited through the limiting vertical rod 116, that is, the limiting horizontal rod 115 can only move up and down. A circular groove is arranged at the contact position between the limiting horizontal rod 115 and the main shaft 114, so as to facilitate the rotation of the main shaft 114. When the arc-shaped top plate 110 does not move in the horizontal height, the friction between the arc-shaped top plate 110, the threaded piece 113 and the threaded segment inside the rotating drum 106 is large due to the impact of the water source, so that the arc-shaped top plate 110 follows the rotation of the rotating drum 106 through the friction.

[0035] As shown in Figures 4 to 6 , the fan ring 109 comprises a rotating ring and a plurality of fan leaves, and the arc-shaped top plate 110 comprises an arc-shaped cover and a connecting ring.

[0036] Specifically, after the height of the arc-shaped top plate 110 is adjusted, the water source is opened, the water source enters the inner pipe 103 through the threaded pipe 101, and then impacts the plurality of fan blades on the fan blade ring 109, thereby driving the fan blade ring 109 to rotate on the limiting ring 108, the fan blade ring 109 drives the water source to rotate in the threaded pipe 101, and the rotating water source also drives the arc-shaped top plate 110 and the rotating drum 106 to rotate on the threaded pipe 101, so that the grooves on the rotating drum 106 rotate outward to spray water, so that the sprayed water flow rotates around the axis of the threaded pipe 101, so that the sprayed water is no longer fixed-point irrigation, but circular coverage, and this mode also avoids long-time irrigation of a point.

[0037] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
