Description

Technical Field

[0001] The utility model relates to the technical field of spray devices, in particular to a low-pressure irrigation spray device. Background Art

[0002] Irrigation sprinklers are mainly used to irrigate crops or artificially transplanted or planted flowers, plants and trees. According to the different water pressures, they can be divided into high pressure, medium pressure and low pressure. Among them, high-pressure irrigation sprinklers are rarely used, and medium pressure is the most used. Generally, medium-pressure sprinklers are used for field crop irrigation, while low pressure is often used for nurseries, young vegetables or grass and flowers in cities to ensure that the plants are not harmed.

[0003] The nozzle of the sprinkler irrigation device is vertically upward. When the low-pressure irrigation sprinkler device is stopped, some impurities can easily enter the nozzle. At the same time, due to the low water pressure of the low-pressure irrigation sprinkler device, some impurities may not be flushed out, which will cause blockage in the nozzle and affect the normal operation of the irrigation sprinkler device. Utility Model Content

[0004] The utility model proposes a low-pressure irrigation sprinkler device to solve the problem that some impurities can easily enter the sprinkler head, and the water flow pressure of the low-pressure irrigation sprinkler device is relatively small, which may fail to flush out some impurities, thus clogging the sprinkler head and affecting the normal operation of the irrigation sprinkler device.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a low-pressure irrigation sprinkler device, comprising a chassis, a rotating tube is rotatably connected to the top of the chassis, three branch pipes are evenly fixedly connected to the outer surface of the rotating tube, a plurality of nozzles are evenly fixedly connected to the outer surface of the branch pipes, and a protective device is arranged on the top of the plurality of nozzles, the protective device comprises a threaded pin, one end of the threaded pin is fixedly connected to one end of the rotating tube, a circular ring is rotatably connected to the outer surface of the threaded pin, a protective plate is evenly fixedly connected to the outer surface of the circular ring, a groove is provided at the bottom of the protective plate, a nut is threadedly connected to the outer surface of the threaded pin, a water inlet pipe is fixedly connected to one side of the chassis, and a positioning device is arranged on the outer surface of the chassis.

[0006] The effect achieved by the above components is: by setting three protective plates and rotating the ring, the ring will drive the protective plates to rotate synchronously until the three protective plates completely block the nozzles on the top of the three branch pipes respectively, and the nozzles completely enter the interior of the groove, and then rotate the nut to make the nut move downward on the outer surface of the threaded pin, so that the nut gradually squeezes the ring until the ring and the rotating tube cannot rotate relative to each other, so that the protective plate can be fixed, and the protective plate can protect the top of the nozzle, which is beneficial to prevent impurities from entering the nozzle and causing the nozzle to be blocked.

[0007] Preferably, a rubber pad is fixedly connected to the top end of the rotating tube, and the outer surface of the threaded pin is inserted into the inner wall of the rubber pad.

[0008] The effect achieved by the above components is that by arranging the rubber pad, the top end of the rotating tube can be replaced to abut against one side of the nut, thereby increasing the friction between the nut and the rotating tube, and further preventing the ring and the protective plate from rotating.

[0009] Preferably, one end of the threaded pin is fixedly connected with a round block, and the outer diameter of the round block is larger than the outer diameter of the threaded pin.

[0010] The effect achieved by the above-mentioned components is: by setting the round block, one end of the threaded pin is blocked, which is helpful to prevent the problem of the nut being separated from the threaded pin and lost due to misoperation.

[0011] Preferably, a sponge pad is fixedly connected to one side of the inner wall of the groove, and the bottom of the sponge pad is flush with the top of the nozzle in the vertical direction.

[0012] The effect achieved by the above components is: by setting the sponge pad, it can abut against the top of the nozzle when the protective plate blocks the nozzle, which can improve the protective performance of the protective plate while playing a certain protective role in the nozzle.

[0013] Preferably, an extension block is fixedly connected to one side of the protective plate, and a magnetic block is fixedly connected to one end of the extension block and the branch pipe, and the two magnetic blocks are magnetically attracted to each other.

[0014] The effect achieved by the above components is: by setting two magnetic blocks, when the two magnetic blocks are close to each other, they will generate a magnetic force of mutual attraction, and the magnetic force can position the protective plate connected to the extension block, thereby facilitating rapid adjustment and fixation of the protective plate.

[0015] Preferably, the positioning device comprises two circular hole blocks, one side of the two circular hole blocks is symmetrically fixedly connected to the outer surface of the chassis, and the inner wall of the circular hole block is provided with a pin, one end of the pin is conical.

[0016] The effect achieved by the above-mentioned components is: by setting the pin, the conical end is convenient for inserting the pin into the ground. At the same time, after the pin is inserted into the ground, the chassis connected to the circular hole block and the ground can be positioned, which is helpful to prevent the irrigation sprinkler device from shifting on the ground during the rotation spraying process, thereby causing the problem of being unable to spray the designated area.

[0017] Preferably, one end of the latch is fixedly connected to an auxiliary block, one side of the auxiliary block is provided with a spring, the outer surface of the latch is inserted into the interior of the spring, and one end of the spring is fixedly connected to one side of the circular hole block.

[0018] The effect achieved by the above components is: by setting the spring, the spring stiffness coefficient used here is relatively low, which mainly plays the role of connecting the pin connected to the auxiliary block and the circular hole block, which is helpful to prevent the pin from easily detaching from the circular hole block and being lost.

[0019] Preferably, the other end of the spring is fixedly connected to an auxiliary ring, the outer surface of the latch is rotatably connected to the inner wall of the auxiliary ring, and one side of the auxiliary ring abuts against one side of the auxiliary block.

[0020] The effect achieved by the above components is: by setting an auxiliary ring, replacing one side of the auxiliary block to connect with one end of the spring, it is helpful to prevent the spring from being damaged by the spring when the latch rotates on the inner wall of the circular hole block.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are:

[0022] In the utility model, three protective plates are provided, which can completely cover the nozzles on the tops of the three branch pipes, and nuts and threaded pins can fix the protective plates, so that the protective plates can protect the tops of the nozzles, which is helpful to prevent impurities from entering the nozzles and causing the nozzles to be blocked.

DETAILED DESCRIPTION

[0029] Example 1, reference Figure 1-Figure 4 As shown, this embodiment discloses a low-pressure irrigation sprinkler device, including a chassis 1, a rotating tube 2 is rotatably connected to the top of the chassis 1, three branch pipes 3 are evenly fixedly connected to the outer surface of the rotating tube 2, a plurality of nozzles 4 are evenly fixedly connected to the outer surface of the branch pipes, a protective device 5 is arranged on the top of the plurality of nozzles 4, the protective device 5 includes a threaded pin 51, one end of the threaded pin 51 is fixedly connected to one end of the rotating tube 2, a ring 52 is rotatably connected to the outer surface of the threaded pin 51, a protective plate 53 is evenly fixedly connected to the outer surface of the ring 52, a groove 54 is provided at the bottom of the protective plate 53, a nut 55 is threadedly connected to the outer surface of the threaded pin 51, and a water inlet pipe 6 is fixedly connected to one side of the chassis 1. A positioning device 7 is provided on the outer surface of the chassis 1. By setting three protective plates 53 and rotating the ring 52, the ring 52 will drive the protective plates 53 to rotate synchronously until the three protective plates 53 completely block the nozzles 4 at the tops of the three branch pipes 3 respectively, and the nozzles 4 completely enter the interior of the groove 54, and then the nut 55 is rotated to make the nut 55 move downward on the outer surface of the threaded pin 51, so that the nut 55 gradually squeezes the ring 52 until the ring 52 and the rotating tube 2 cannot rotate relative to each other, so that the protective plate 53 can be fixed, and the protective plate 53 can protect the top of the nozzle 4, which is beneficial to prevent the nozzle 4 from being blocked by impurities entering the nozzle 4.

[0030] Reference Figure 2-Figure 4 As shown, a rubber pad 56 is fixedly connected to the top of the rotating tube 2, and the outer surface of the threaded pin 51 is inserted into the inner wall of the rubber pad 56. By providing the rubber pad 56, the top of the rotating tube 2 can be replaced to abut against one side of the nut 55, thereby increasing the friction between the nut 55 and the rotating tube 2, and further preventing the ring 52 and the protective plate 53 from rotating; a round block 57 is fixedly connected to one end of the threaded pin 51, and the outer diameter of the round block 57 is larger than the outer diameter of the threaded pin 51. By providing the round block 57, one end of the threaded pin 51 is blocked, which is beneficial to prevent the problem of the nut 55 being separated from the threaded pin 51 and lost due to misoperation.

[0031] Reference Figure 2-Figure 4As shown, a sponge pad 58 is fixedly connected to one side of the inner wall of the groove 54, and the bottom of the sponge pad 58 is flush with the top of the nozzle 4 in the vertical direction. By setting the sponge pad 58, it can abut against the top of the nozzle 4 when the protective plate 53 blocks the nozzle 4, which can improve the protection performance of the protective plate 53 and at the same time play a certain protective role in the nozzle 4; an extension block 59 is fixedly connected to one side of the protective plate 53, and the extension block 59 and one end of the branch pipe 3 are fixedly connected with a magnetic block 510, and the two magnetic blocks 510 are magnetically attracted to each other. By setting two magnetic blocks 510, the two magnetic blocks 510 will generate a mutually attractive magnetic force when they are close to each other, and the magnetic force can position the protective plate 53 connected to the extension block 59, thereby facilitating the rapid adjustment and fixation of the protective plate 53.

[0032] Reference Figure 2 and Figure 5 As shown, the positioning device 7 includes two circular hole blocks 71, one side of the two circular hole blocks 71 is symmetrically fixedly connected to the outer surface of the chassis 1, and a pin 72 is inserted into the inner wall of the circular hole block 71. One end of the pin 72 is tapered. By setting the pin 72, the tapered end is convenient for inserting the pin 72 into the ground. At the same time, after the pin 72 is inserted into the ground, the chassis 1 connected to the circular hole block 71 can be positioned between the ground, which is beneficial to prevent the irrigation sprinkler from shifting on the ground during the rotation spraying process, thereby causing the problem of failure to spray the designated area.

[0033] Reference Figure 2 and Figure 5 When the bolt 72 is in the closed position, the spring 74 is pressed against the locking rim 74 so that the bolt 72 can penetrate the locking rim 74 to stop the bolt 72 from being lost.

[0034] Working principle: when it is necessary to protect the nozzle 4, rotate the nut 55 to make the nut 55 away from the rubber pad 56, and then rotate the ring 52, the ring 52 will drive the protective plate 53 to rotate synchronously, until the three protective plates 53 completely cover the nozzles 4 on the tops of the three branch pipes 3 respectively, and the nozzle 4 completely enters the interior of the groove 54, and the top of the nozzle 4 abuts against the bottom of the sponge pad 58. At this time, the magnetic block 510 on one side of the extension block 59 and the magnetic block 510 at one end of the branch pipe 3 will be magnetically attracted to each other, thereby positioning the protective plate 53 and the ring 52, and finally rotate the nut 55 to make the nut 55 move downward on the outer surface of the threaded pin 51, so that the nut 55 gradually squeezes the rubber pad 56 on the top of the ring 52 until the ring 52 and the rotating tube 2 are in contact. If the disc 72 and the ground cannot rotate relative to each other, the protective plate 53 can be fixed, and the protective plate 53 can protect the top of the nozzle 4, which is beneficial to prevent impurities from entering the nozzle 4 and causing the nozzle 4 to be blocked; when it is necessary to fix the disc and the ground, the conical ends of the two pins 72 are inserted into the ground. During this process, the auxiliary block 73 and the circular hole block 71 will gradually squeeze the spring 74, causing the spring 74 to deform. The precision coefficient of the spring 74 is small, and no large thrust will be generated on the pin 72 and the auxiliary block 73. Then, the chassis 1 connected to the circular hole block 71 and the ground can be positioned, which is beneficial to prevent the irrigation sprinkler device from shifting on the ground during the rotation spraying process, thereby causing the designated area to be unable to be sprayed.
