Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment, specifically a high-standard irrigation sprinkler head device for farmland. Background Technology

[0002] High-standard farmland is a specific type of arable land characterized by flat, contiguous land with complete supporting facilities. In the construction of high-standard farmland, it is necessary to comprehensively and uniformly improve various facilities within the farmland before it can be put into use. Among these, the construction of the irrigation system is particularly important.

[0003] In the process of irrigating farmland, the corresponding farmland is usually irrigated manually or water is sprayed onto the crops through sprinkler irrigation equipment and then falls onto the crops or soil.

[0004] However, after long-term observation, it has been found that the sprinkler pipes cause some farmland to be over-watered while others are under-watered during the irrigation process. This uneven irrigation affects the growth of crops in high-standard farmland. Moreover, after long-term use, the surface of the nozzles will gradually be blocked by scale, affecting the irrigation of crops. When clearing the nozzles, it is often necessary to disassemble the nozzles. Since there are many irrigation nozzles used in farmland, disassembling them one by one is time-consuming and labor-intensive, requiring a lot of manpower and increasing irrigation costs. Utility Model Content

[0005] The purpose of this invention is to provide a high-standard irrigation sprinkler device for farmland to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-standard farmland irrigation sprinkler head device, comprising: a sprinkler head body, a connecting device on the upper surface of the sprinkler head body, a plurality of equally spaced spray holes on the outer surface of the sprinkler head body, an irrigation device on the inner surface of the sprinkler head body, the irrigation device comprising: a driving device, a rotating shaft rotatably mounted on the output end of the driving device, rotating blades sleeved on the outer surface of the bottom end of the rotating shaft, a baffle plate rotatably mounted on the top end of the rotating shaft, and a self-cleaning mechanism on the outer surface of the top end of the rotating shaft;

[0007] The self-cleaning mechanism includes: a fixed base, an inner groove on the inner surface of the fixed base, a first elastic element on the bottom surface of the inner groove, a connecting rod elastically connected to the output end of the first elastic element, a support plate fixedly installed at the end of the connecting rod away from the first elastic element, a second elastic element on the inner surface of the support plate, a scraper elastically connected to the output end of the second elastic element, and several flexible brushes on the side surface of the scraper.

[0008] Preferably, the connecting device includes: a connecting seat, the inner surface of which is provided with external threads, and the lower surface of the connecting seat is fixedly connected to the nozzle body.

[0009] Preferably, the inner surface of the connecting seat is threaded with a connecting pipe, and the outer surface of the bottom end of the connecting pipe is provided with an internal thread corresponding to the external thread. The connecting pipe is threadedly connected to the connecting seat through the threaded engagement of the external thread and the internal thread.

[0010] Preferably, the upper surface of the connecting pipe is provided with a water inlet pipe, which is rectangular in shape. Several irrigation devices are arranged at equal intervals on the inner surface of the water inlet pipe in the horizontal direction, and a sealing gasket is provided at the connection between the water inlet pipe and the connecting pipe.

[0011] Preferably, the first elastic element includes: a sliding column, which is fixedly installed on the bottom surface of the inner groove, and a first spring is sleeved on the outer surface of the sliding column, and the sliding column and the first spring form the first elastic element.

[0012] Preferably, the second elastic element includes: a pressure rod that penetrates the inner surface of the support plate, a second spring that is provided at the connection between the pressure rod and the support plate, and the second spring that is sleeved on the outer surface of the pressure rod. The pressure rod and the second spring together form the second elastic element.

[0013] Preferably, the rotating blade is curved, and the self-cleaning mechanism extends into the inner surface of the nozzle by the centrifugal force of the drive device during rotation.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model proposes a high-standard irrigation sprinkler head device for farmland;

[0016] 1. By setting up an irrigation device, the rotating blades on the shaft are driven by a drive device to rotate at a constant speed. The water flow is dispersed by the rotating blades, increasing the dispersion area of ​​the water flow. The dispersed water flow is sprayed out through several equally spaced nozzles on the outer surface of the nozzle body, increasing the irrigation area and covering every corner of the farmland. The curved shape of the rotating blades further increases the contact area between the water flow and the rotating blades, allowing the water flow to be better dispersed, so that the crops in the high-standard farmland are evenly and fully irrigated.

[0017] 2. By setting up a self-cleaning mechanism, the baffle plate is rotated by the drive device, thus intermittently interrupting the water flow. This causes the pressure on the connecting rod to fluctuate as the water falls, which in turn compresses the first spring on the sliding column in the inner groove of the connecting rod in the fixed seat. This causes the cleaning mechanism on one end of the connecting rod to slide up and down. Simultaneously, the centrifugal force from the rotation of the drive device causes the pressure rod to compress the second spring, allowing the flexible brush on the scraper to extend into the nozzle and unclog the scale in the nozzle. Since the flexible brush is made of flexible material, it does not affect the rotation of the scraper. Therefore, the nozzle can be unclogged without disassembling the nozzle body, improving applicability and reducing irrigation costs. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: a high-standard irrigation sprinkler head device for farmland;

[0026] Example 1:

[0027] In order to ensure that crops in high-standard farmland are evenly and fully irrigated, a number of equally spaced spray holes 7 are provided on the outer surface of the nozzle body 6, and an irrigation device 8 is provided on the inner surface of the nozzle body 6. The irrigation device 8 includes: a drive device 801, a rotating shaft 802 is rotatably mounted on the output end of the drive device 801, and a rotating blade 803 is sleeved on the outer surface of the bottom end of the rotating shaft 802. The rotating blade 803 is curved.

[0028] The driving device 801 drives the rotating blades 803 on the rotating shaft 802 to rotate at a constant speed. The water flow is dispersed by the rotating blades 803, increasing the dispersion area of ​​the water flow. The dispersed water flow is sprayed out through several equally spaced nozzles 7 on the outer surface of the nozzle body 6, increasing the irrigation area and covering every corner of the farmland. The curved shape of the rotating blades 803 further increases the contact area between the water flow and the rotating blades 803, allowing the water flow to be dispersed better.

[0029] The upper surface of the connecting pipe 2 is provided with a water inlet pipe 1. The water inlet pipe 1 is rectangular in shape. Several irrigation devices 8 are equidistantly distributed on the inner surface of the water inlet pipe 1 in the horizontal direction. A sealing gasket 10 is provided at the connection between the water inlet pipe 1 and the connecting pipe 2.

[0030] The rectangular shape of the inlet pipe 1 helps to distribute water more evenly, reduce water flow resistance and pressure loss, improve irrigation efficiency, and the internal corners of the square pipe can reduce the accumulation of dirt and impurities, thus avoiding pipe blockage.

[0031] Example 2:

[0032] Based on Embodiment 1, in order to realize the up and down sliding of the cleaning mechanism, a baffle plate 804 is rotatably installed at the top of the rotating shaft 802. The outer surface of the top of the rotating shaft 802 is provided with a self-cleaning mechanism. The self-cleaning mechanism includes: a fixed seat 9, an inner groove 901 is opened on the inner surface of the fixed seat 9, a first elastic member is provided on the bottom surface of the inner groove 901, a connecting rod 904 is elastically connected to the output end of the first elastic member, a sliding column 902 is fixedly installed on the bottom surface of the inner groove 901, and a first spring 903 is sleeved on the outer surface of the sliding column 902. The sliding column 902 and the first spring 903 form the first elastic member.

[0033] The drive device 801 drives the baffle plate 804 to rotate, thereby intermittently interrupting the water flow. This causes the pressure on the connecting rod 904 to fluctuate as the water flows down, which in turn causes the connecting rod 904 to compress the first spring 903 on the slide column 902 in the inner groove 901 of the fixed seat 9, thereby driving the cleaning mechanism on the support plate 905 at one end of the connecting rod 904 to slide up and down.

[0034] Example 3:

[0035] In order to clear the scale in the nozzle 7, in addition to the second embodiment, a support plate 905 is fixedly installed at the end of the connecting rod 904 away from the first elastic member. The inner surface of the support plate 905 is provided with a second elastic member. The output end of the second elastic member is elastically connected to a scraper 908. The side surface of the scraper 908 is provided with several flexible brushes 909. The pressure rod 906 penetrates the inner surface of the support plate 905. A second spring 907 is provided at the connection between the pressure rod 906 and the support plate 905. The second spring 907 is sleeved on the outer surface of the pressure rod 906. The pressure rod 906 and the second spring 907 form the second elastic member. The self-cleaning mechanism extends into the inner surface of the nozzle 7 by the centrifugal force when the drive device 801 rotates.

[0036] The centrifugal force generated when the drive device 801 rotates causes the pressure rod 906 to compress the second spring 907, which in turn causes the flexible brush 909 on the scraper 908 to extend into the nozzle 7 and unclog the scale in the nozzle 7. Since the flexible brush 909 is made of flexible material, it does not affect the rotation of the scraper 908, so the nozzle 7 can be unclogged without disassembling the nozzle body 6.

[0037] Working principle: First, connect one end of the inlet pipe 1 to the water pipe, start the water pump to make the water flow into the connecting pipe 2, and then into the nozzle body 6. The drive device 801 drives the rotating blades 803 on the rotating shaft 802 to rotate at a constant speed. The water flow is dispersed by the rotating blades 803, increasing the dispersion area of ​​the water flow. The dispersed water flow is sprayed out through several equally spaced spray holes 7 on the outer surface of the nozzle body 6, increasing the irrigation area and covering every corner of the farmland. The curved shape of the rotating blades 803 further increases the contact area between the water flow and the rotating blades 803, making the water flow more dispersed. Secondly, the drive device 801 simultaneously drives the baffle plate 804 to rotate, thereby further dispersing the water flow. Intermittent interruption causes the pressure on the connecting rod 904 to fluctuate as the water flows down. This causes the connecting rod 904 to compress the first spring 903 on the sliding column 902 within the inner groove 901 of the fixed base 9. This drives the cleaning mechanism on the support plate 905 at one end of the connecting rod 904 to slide up and down. Simultaneously, the centrifugal force from the rotation of the drive device 801 causes the pressure rod 906 to compress the second spring 907. This allows the flexible brush 909 on the scraper 908 to extend into the nozzle 7 and unclog the scale inside. Since the flexible brush 909 is made of flexible material, it does not affect the rotation of the scraper 908. Therefore, the nozzle 7 can be unclogged without disassembling the nozzle body 6, improving applicability and reducing irrigation costs.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
