Technical Field

[0001] The utility model relates to the technical field of sprinkler irrigation, in particular to a sprinkler head structure of sprinkler irrigation equipment. Background Art

[0002] Sprinkler irrigation is an irrigation method that uses a water pump and pipe system or utilizes the drop of natural water sources to spray water with a certain pressure into the air, which then breaks into small droplets or forms mist and falls onto plants and the ground.

[0003] When performing sprinkler irrigation, sprinkler irrigation equipment is required. When spraying water, water needs to be sprayed out through a sprinkler head. However, some existing sprinkler head devices usually directly transport water to the inside of the sprinkler head when in use, and then spray it out through the water spray holes on the sprinkler head. Therefore, when not spraying water, the water spray holes cannot be well protected, causing external impurities to enter the inside of the sprinkler head, which easily causes the sprinkler head to be blocked.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] Please refer to Figure 1 - Figure 4 ,in, Figure 1 It is a schematic diagram of the overall structure of the utility model; Figure 2It is a cross-sectional view of the water storage tank of the utility model; Figure 3 For this utility model Figure 2 The enlarged structural diagram at A in the middle; Figure 4 For this utility model Figure 2 The structure diagram is enlarged at B. The sprinkler head structure of the sprinkler irrigation equipment comprises: a water storage tank 1, a sprinkler head 2 is fixedly connected to the top of the water storage tank 1, and a water spray hole 4 is opened on the top of the sprinkler head 2.

[0023] In this method, when performing sprinkler irrigation, the bottom of the water tank 1 is connected to the external water supply pipe, and then water is transported to the inside of the water tank 1 through the water supply pipe, and then the water enters the inside of the nozzle 2 and is sprayed out through the water spray hole 4, thereby realizing sprinkler irrigation.

[0024] In the above-mentioned manner, a guide rod 9 is fixedly installed inside the water tank 1, a connecting plate 11 is slidably connected on the surface of the guide rod 9, a return spring 10 is movably sleeved on the surface of the guide rod 9, and the two ends of the return spring 10 are respectively fixedly connected to the top of the connecting plate 11 and the inner wall of the water tank 1, a sealing baffle 14 is fixedly installed on one end of the connecting plate 11, a connecting rod 13 is fixedly installed on the upper end of the sealing baffle 14, a sliding sleeve 12 is fixedly installed on the upper end of the connecting rod 13, a connecting block 21 is slidably connected inside the sliding sleeve 12, a driving groove 15 is provided on the surface of the connecting block 21, a sliding rod 16 is fixedly installed inside the sliding sleeve 12, and the sliding rod 16 is slidably connected to the inside of the driving groove 15, and the shape of the driving groove 15 is inclined, a rotating shaft 8 is fixedly installed on the top of the connecting block 21, and the upper end of the rotating shaft 8 rotates through the top of the spray head 2, and a protective cover 3 is fixedly installed on the upper end of the rotating shaft 8, and the protective cover 3 coincides with the water spray hole 4.

[0025] In this manner, water enters the water storage tank 1 and impacts the sealing baffle 14, thereby causing the sealing baffle 14 to move upward, causing the connecting plate 11 to slide on the surface of the guide rod 9 and squeeze the reset spring 10, thereby causing the connecting rod 13 and the sliding sleeve 12 to move upward. At the same time, since the sealing baffle 14 is restricted by the connecting plate 11 and the guide rod 9 and cannot rotate, it can only move up and down. When the sliding sleeve 12 moves upward, the sliding rod 16 will slide inside the driving groove 15, causing the sliding rod 16 to squeeze the arc surface of the driving groove 15, thereby causing the connecting rod 13 and the sliding sleeve 12 to move upward. The block 21 and the rotating shaft 8 rotate, thereby causing the protective cover 3 to rotate, and thereby causing the protective cover 3 to no longer seal the water spray hole 4. When water is no longer supplied to the interior of the water storage tank 1, the sealing baffle 14 will be reset by the elastic force of the reset spring 10, thereby causing the rotating shaft 8 to rotate in the opposite direction, thereby causing the protective cover 3 to seal the water spray hole 4, thereby facilitating the sealing of the water spray hole 4 and preventing external impurities from entering the interior of the water spray hole 4 and causing clogging of the water spray hole 4 when the water storage tank 1 and the nozzle 2 are not in use, thereby improving the protection effect of the water spray hole 4 and avoiding clogging of the nozzle 2 to the greatest extent.

[0026] In the above manner, a lifting frame 5 is fixedly mounted on the surface of the sliding sleeve 12 , a circular ring 6 is fixedly mounted on the lifting frame 5 , and a cleaning rod 7 corresponding to the water spray hole 4 is fixedly mounted on the top of the circular ring 6 .

[0027] In this method, when the sliding sleeve 12 moves upward, the lifting frame 5 will move upward, and then the ring 6 and the cleaning rod 7 will move upward, so that the cleaning rod 7 will enter the inside of the water spray hole 4, and push the impurities blocked inside the water spray hole 4, thereby facilitating the cleaning of the water spray hole 4, improving the cleaning effect of the water spray hole 4, preventing blockage, and thus improving the sprinkler irrigation effect.

[0028] In the above method, a support plate 17 is fixedly installed on the sealing baffle 14, a hanging rod 18 is fixedly installed on the bottom of the support plate 17, a drainage hole 19 is opened at the bottom of the water tank 1, the hanging rod 18 is located inside the drainage hole 19, and a sealing plug 20 is fixedly installed at the lower end of the hanging rod 18, and the sealing plug 20 is consistent with the drainage hole 19.

[0029] In the present embodiment, when the sealing baffle 14 moves upward, the supporting plate 17 will move upward along with the sealing baffle 14, thereby causing the suspension rod 18 and the sealing plug 20 to move upward, thereby causing the sealing plug 20 to enter the interior of the drainage hole 19 to seal the drainage hole 19. When the sealing baffle 14 is reset, the supporting plate 17 will move downward, thereby causing the sealing plug 20 to no longer seal the drainage hole 19, thereby facilitating the discharge of water inside the water tank 1 through the drainage hole 19, thereby preventing algae from growing on the water tank 1 and the nozzle 2 when they are not used for a long time, thereby causing blockage of the water spray hole 4, thereby improving the protection of the water tank 1 and the nozzle 2.

[0030] The working principle of the nozzle structure of the sprinkler irrigation equipment provided by the utility model is as follows: the bottom of the water tank 1 is connected to the external water supply pipe, and then water is transported to the inside of the water tank 1 through the water supply pipe, and then the water enters the inside of the nozzle 2 and is sprayed out through the water spray hole 4, thereby realizing sprinkler irrigation.

[0031] When water enters the interior of the water tank 1, it will impact the sealing baffle 14, thereby causing the sealing baffle 14 to move upward, causing the connecting plate 11 to slide on the surface of the guide rod 9 and squeeze the return spring 10, thereby causing the connecting rod 13 and the sliding sleeve 12 to move upward. At the same time, since the sealing baffle 14 is restricted by the connecting plate 11 and the guide rod 9 and cannot rotate, it can only move up and down. When the sliding sleeve 12 moves upward, the sliding rod 16 will slide inside the driving groove 15, causing the sliding rod 16 to squeeze the arc surface of the driving groove 15, thereby causing the connecting block 21 and the rotating shaft 8 to rotate, thereby causing the protective cover 3 to rotate, thereby causing the protective cover 3 to no longer seal the water spray hole 4. When water is no longer supplied to the interior of the water tank 1, the sealing baffle 14 will be reset by the elastic force of the return spring 10, thereby causing the rotating shaft 8 to rotate in the opposite direction, thereby causing the protective cover 3 to seal the water spray hole 4, thereby facilitating the sealing of the water spray hole 4.

[0032] When the sliding sleeve 12 moves upward, the lifting frame 5 moves upward, and then the ring 6 and the cleaning rod 7 move upward, so that the cleaning rod 7 enters the inside of the water spray hole 4 to push the impurities blocked in the water spray hole 4, thereby facilitating the cleaning of the water spray hole 4.

[0033] When the sealing baffle 14 moves upward, the support plate 17 will move upward along with the sealing baffle 14, thereby moving the suspension rod 18 and the sealing plug 20 upward, and then the sealing plug 20 will enter the drainage hole 19 to seal the drainage hole 19. When the sealing baffle 14 is reset, the support plate 17 will move downward, and then the sealing plug 20 will no longer seal the drainage hole 19, thereby facilitating the discharge of water inside the water tank 1 through the drainage hole 19, thereby preventing algae from growing when the water tank 1 and the nozzle 2 are not used for a long time.

[0034] Compared with the related art, the sprinkler head structure of the sprinkler irrigation equipment provided by the utility model has the following beneficial effects:

[0035] The utility model provides a sprinkler head structure of a sprinkler irrigation device, in which a sealing baffle 14 is reset by the elastic force of a reset spring 10, thereby causing a rotating shaft 8 to rotate in the opposite direction, thereby causing a protective cover 3 to seal a water spray hole 4, thereby facilitating sealing of the water spray hole 4, preventing external impurities from entering the water spray hole 4 when a water storage tank 1 and a sprinkler head 2 are not in use, thereby causing clogging of the water spray hole 4, thereby improving the protective effect of the water spray hole 4, and avoiding clogging of the sprinkler head 2 to the greatest extent.

[0036] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
