Description

Technical Field

[0001] The utility model relates to the field of sprinkler irrigation devices, and more specifically, to a sprinkler irrigation device. Background Art

[0002] Sprinkler irrigation devices can generally be divided into fixed, semi-fixed and mobile types. Among them, fixed sprinkler irrigation settings are often used in cash crop areas and high-yield crop areas that require frequent irrigation due to reasons such as high efficiency, less land occupation, and comprehensive use.

[0003] Sprinkler irrigation equipment generally consists of parts such as a water inlet pipe, a water pump, a distribution pipe, a distribution pipe and a sprinkler head. By means of a water pump and a pipeline system, water is sprayed into the air and dispersed into small water droplets to fall on crops and the ground for irrigation operations.

[0004] However, for existing sprinkler irrigation devices, due to the large spraying range of the sprinkler head, the degree of water droplet impact near the sprinkler head is greater than that in the distance, and the crops near the sprinkler head will also receive more irrigation water than the crops in the distance. As a result, the air in the soil near the sprinkler head is compressed by water, which affects the normal respiration of crop roots and hinders the normal growth of crops.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model

[0006] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a sprinkler irrigation device that can avoid the situation where the air in the soil is compressed by water, thereby affecting the normal respiration of crop roots and hindering the normal growth of crops.

Specific implementation manner

[0022] The following combines the drawings and embodiments to describe the present utility model in detail.

[0023] A sprinkler irrigation device, as Figures 1 - 5 shown, includes a water delivery pipe 1 and a water distribution pipe 2 fixedly connected to the water delivery pipe 1. A sprinkler head 3 is rotatably connected to the water distribution pipe 2. A receiving tray 4 is fixedly connected to the water distribution pipe 2. A plurality of through holes 5 are formed in the receiving tray 4, which can block the water near the sprinkler head 3 from directly irrigating the crops near the sprinkler head 3 and can make the water stay on the receiving tray 4. A driving assembly for driving the sprinkler head 3 to rotate is provided on the water distribution pipe 2 and the sprinkler head 3. A local irrigation assembly for irrigating the crops near the water distribution pipe 2 is provided on the receiving tray 4. A circulating assembly for returning water to the water delivery pipe 1 is provided on the receiving tray 4. When irrigation is required, the water pump can be turned on to convey water into the water delivery pipe 1, and then the water will be distributed to each water distribution pipe 2 for irrigation through each sprinkler head 3. When irrigation is carried out, the driving assembly can be turned on to drive the sprinkler head 3 to rotate for irrigation. When the sprinkler head 3 rotates, the water near the sprinkler head 3 will be blocked by the receiving tray 4 and stay on the receiving tray 4. Then the sprinkler head 3 will drive the local irrigation assembly to irrigate the crops at the water distribution pipe 2, and at the same time, the circulating assembly will be triggered to re-introduce the excess water into the water delivery pipe 1 for circulation. By this method, the air in the soil can be prevented from being compressed by water, thereby affecting the normal respiration of the crop roots and causing the normal growth of the crops to be blocked. At the same time, water resource waste can also be avoided.

[0024] As Figures 1 - 2 shown, the driving assembly includes a motor 6 fixedly connected to the water distribution pipe 2, a first gear 7 fixedly connected to the output shaft of the motor 6, and a second gear 8 fixedly connected to the sprinkler head 3. The first gear 7 and the second gear 8 are meshed with each other. When the sprinkler head 3 needs to rotate, the motor 6 can be turned on to make the first gear 7 rotate and drive the second gear 8 to rotate. When the second gear 8 rotates, the sprinkler head 3 can be driven to rotate.

[0025] As Figure 1 , Figure 2 , Figure 4As shown in the figure, the local irrigation assembly includes a positioning ring 9 rotatably connected to the water distribution pipe 2 above the receiving tray 4, several scraping rods 10 fixedly connected to the positioning ring 9, and a connecting rod 11 fixedly connected to one of the scraping rods 10. The other end of the connecting rod 11 is fixedly connected to the nozzle 3. The scraping rod 10 is in contact with the receiving tray 4. When the nozzle 3 rotates, the scraping rod 10 can be driven to rotate through the connecting rod 11, so as to drive other scraping rods 10 to rotate together on the receiving tray 4. When the scraping rod 10 rotates, the scraping rod 10 can push the water blocked by the receiving tray 4 and staying on the receiving tray 4, and make the water flow upward along the inner wall of the receiving tray 4 and fall from the through hole 5 to the crops near the water distribution pipe 2, thus completing local irrigation.

[0026] As Figure 1 , Figure 2 , Figure 4 shown, a groove 12 is formed in the scraping rod 10, and an inclined plate 13 is fixedly connected in the groove 12. When local irrigation is carried out, through the arrangement of the inclined plate 13, the water can move upward along the inner wall of the receiving tray 4 better, avoiding uneven local irrigation.

[0027] As Figure 1 , Figure 2 , Figure 5 shown, the apertures of several through holes 5 gradually decrease near the water distribution pipe 2 and are obliquely arranged. When local irrigation is carried out, the gradually decreasing aperture can avoid the situation that the water flow passing through the through hole 5 near the water distribution pipe 2 is more than that passing through the through hole 5 far from the water distribution pipe 2, and the obliquely arranged through holes 5 can make it easier for the scraping rod 10 to sprinkle water from the through holes 5 during scraping irrigation.

[0028] As Figures 1 - 3 shown, a first through groove 14 is formed at the bottom side of the receiving tray 4. The circulation assembly includes a return water pipe 15 fixedly connected to the first through groove 14, a fixing plate 16 fixedly connected to one side of the return water pipe 15 near the first through groove 14, a sliding rod 17 slidably connected to the fixing plate 16, a trigger block 18 fixedly connected to the sliding rod 17, and a one-way valve 19 fixedly connected to the return water pipe 15. A spring 20 is sleeved between the trigger block 18 and the fixing plate 16 on the sliding rod 17. The return water pipe 15 is fixedly connected and communicated with the water delivery pipe 1. The outer wall of the trigger block 18 is in contact with the inner wall of the return water pipe 15. During local irrigation, the scraping rod 10 will contact the trigger block 18 and press the trigger block 18 into the return water pipe 15. At this time, the spring 20 is in a compressed state. When the trigger block 18 moves into the return water pipe 15, the water in the return water pipe 15 will be pressed down by the trigger block 18 and return to the water delivery pipe 1 through the one-way valve 19. When the scraping rod 10 no longer contacts the trigger block 18, the spring 20 will reset, and the water in the receiving tray 4 enters the return water pipe 15 through the first through groove 14. In this way, the water circulation operation can be carried out reciprocally, avoiding the water in the receiving tray 4 being too full and directly leaking from the through hole 5.

[0029] AsFigures 2 - 3 As shown in the figure, the triggering block 18 is hemispherical on the side close to the scraping rod 10. When the scraping rod 10 contacts the triggering block 18, it is easier to press down the triggering block 18 without damaging the scraping rod 10, so as to ensure that the scraping rod 10 can work normally.

[0030] As Figures 1 - 3 shown, a slider 21 is slidably connected between the return water pipe 15 and the one-way valve 19 and the fixing plate 16. A second through groove 22 with the same inner diameter as the return water pipe 15 is formed on the slider 21. A filter screen 23 is fixedly connected to the side of the second through groove 22 close to the one-way valve 19. After the irrigation device works for a period of time, the slider 21 can be pulled out from the return water pipe 15, and then the impurities on the filter screen 23 can be cleaned, so as to avoid the blockage of the return water pipe 15.

[0031] Working principle: When irrigation is needed, the water pump can be turned on to convey water into the water delivery pipe 1, and then the water will be distributed to each water distribution pipe 2 for irrigation through each sprinkler head 3. When irrigating, the motor 6 can be turned on to make the first gear 7 rotate and drive the second gear 8 to rotate. When the second gear 8 rotates, the sprinkler head 3 can be driven to rotate for irrigation. When the sprinkler head 3 rotates, the connecting rod 11 will drive one scraping rod 10 to rotate, thereby driving other scraping rods 10 to rotate together on the receiving tray 4. When the scraping rod 10 rotates, the scraping rod 10 can push the water blocked by the receiving tray 4 and staying on the receiving tray 4, and make the water flow upward along the inner wall of the receiving tray 4 and fall from the through hole 5 onto the crops near the water distribution pipe 2 to irrigate the crops at the water distribution pipe 2. While performing local irrigation, the scraping rod 10 will contact the triggering block 18 and press the triggering block 18 into the return water pipe 15. At this time, the spring 20 is in a compressed state. When the triggering block 18 moves into the return water pipe 15, the water in the return water pipe 15 will be pressed down by the triggering block 18 and return to the water delivery pipe 1 through the one-way valve 19. When the scraping rod 10 no longer contacts the triggering block 18, the spring 20 will reset, and the water in the receiving tray 4 will enter the return water pipe 15 through the first through groove 14, and the water circulation operation can be carried out in this way.

[0032] In this way, it is possible to avoid the air in the soil being compressed by water, thereby affecting the normal respiration of the roots of the crops and causing the normal growth of the crops to be hindered, and it is also possible to avoid the water in the receiving tray 4 being too full and directly leaking out from the through hole 5.

[0033] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, several improvements and retouches made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
