Description

Technical Field

[0001] The invention belongs to the technical field of agricultural irrigation equipment, and in particular relates to a drip irrigation emitter and a drip irrigation device. Background Art

[0002] Drip irrigation is a type of local irrigation, which consists of five parts: the head hub, the main pipe, the branch pipe, the capillary tube, and the emitter. The head hub is responsible for water intake, pressurization and water treatment, and is composed of a delivery pump, a fertilizer tank, a filter, a pressure gauge, a flow meter and other components; ② The main pipe plays a role in water delivery; ③ The branch pipe plays a role in water distribution, and distributes irrigation water to the irrigation area according to the size of the control area and the water demand of the crop; ④ The capillary tube is connected to the branch pipe to send water to the vicinity of the root of the crop; ⑤ The emitter, including: drippers, water outlets, etc., each with different types and shapes, is used to evenly wet the soil at the root of the crop. The drip irrigation capillary tube and emitter are arranged under the surface, which is called underground drip irrigation. The outstanding advantage of drip irrigation is that it saves a lot of water, especially underground drip irrigation, because irrigation water can significantly reduce soil surface evaporation, and the utilization efficiency of irrigation water is higher. The high degree of automation of drip irrigation can keep the soil moisture in the optimal state at all times.

[0003] However, the emitter is often clogged. In the related art, a plug or continuous rotation of the impeller is used to prevent or reduce the probability of the emitter being clogged. However, mud will cause the plug to be blocked, resulting in the plug being unable to open and close normally, and there is still a risk of emitter clogging. The solution of using an impeller to rotate and stir to prevent mud from clogging the emitter requires increasing the water supply pressure, which increases the energy consumption of the drip irrigation system.

[0038] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0039] The embodiment of the present invention further proposes a drip irrigation emitter 1000, comprising a housing 1, a cover 2, an opening component 4, an elastic pad 3 and a dredging head 5, wherein the housing 1 has a receiving cavity 101, the bottom of the housing 1 has a water outlet 1022, the cover 2 is detachably connected to the housing 1, the cover 2 is used to seal the receiving cavity 101, the elastic pad 3 is located between the housing 1 and the cover 2, the elastic pad 3 divides the receiving cavity 101 into a first cavity 1011 and a second cavity 1012, and the opening component 4 is installed on the elastic pad 3 The opening component 4 has an open state and a closed state. In the open state, the first cavity 1011 and the second cavity 1012 are connected. In the closed state, the first cavity 1011 and the second cavity 1012 are independent of each other. The dredging head 5 is detachably connected to the elastic pad 3. The dredging head 5 is located in the second cavity 1012. The dredging head 5 is located directly above the water outlet 1022, and the dredging head 5 can be moved close to or away from the water outlet 1022 driven by the elastic pad 3 to allow the dredging head 5 to move in the water outlet 1022.

[0040] Specifically, Figure 1 and Figure 2 As shown, the upper end of the shell 1 has an opening, and the interior of the shell 1 is hollow to form a accommodating chamber 101. One end of the shell 1 has a connector 16, which is connected to the drip irrigation tape 15. The water outlet 1022 is located at the bottom of the shell 1, and the water outlet 1022 is connected to the accommodating chamber 101. The cover body 2 is located above the shell 1, and the cover body 2 seals the accommodating chamber 101. The elastic pad 3 is pressed between the shell 1 and the cover body 2. The elastic pad 3 is elastic, that is, the elastic pad 3 can be stretched or contracted. For example, the elastic pad 3 can be a rubber pad.

[0041] The elastic pad 3 divides the accommodating cavity 101 into a first cavity 1011 and a second cavity 1012 which are distributed up and down, and the volume of the first cavity 1011 is smaller than that of the second cavity 1012. There is an opening component 4 between the first cavity 1011 and the second cavity 1012. When the opening component 4 is in an open state, the first cavity 1011 and the second cavity 1012 are connected. When the opening component 4 is in a closed state, the first cavity 1011 and the second cavity 1012 are relatively independent.

[0042] It should be noted that when the pressure in the second cavity 1012 reaches the opening threshold of the opening component 4, the opening component 4 opens the first cavity 1011 and the second cavity 1012, otherwise, the opening component 4 is in a closed state.

[0043] When the opening component 4 is in the open state, the liquid in the second cavity 1012 enters the first cavity 1011. After the liquid flows into the first cavity 1011, the elastic pad 3 bulges downward under the conditions of hydraulic pressure and liquid deadweight, thereby driving the unclogging head 5 to move downward. Conversely, when the opening component 4 is in the closed state, the first cavity 1011 lacks water pressure and liquid deadweight, and bulges upward under the action of the liquid pressure in the second cavity 1012, and the unclogging head 5 moves upward.

[0044] It should be noted that the water outlet 1022 is connected to the second cavity 1012, and the connecting head 16 is also connected to the second cavity 1012. When the sprinkler 1000 drips normally, the liquid enters the second cavity 1012 from the connecting head 16 and is then discharged through the water outlet 1022. When the water outlet 1022 is blocked, the liquid in the second cavity 1012 cannot be discharged smoothly, and the connecting head 16 continues to take in water, resulting in an increase in the hydraulic pressure in the second cavity 1012. When the hydraulic pressure increases to the opening threshold of the opening component 4, the opening component 4 is pushed open under the action of the hydraulic pressure and enters the open state, so that the liquid in the second cavity 1012 enters the first cavity 1011, thereby driving the elastic pad 3 to bulge downward, thereby driving the dredging head 5 to move downward.

[0045] When the unclogging head 5 is inserted into the water outlet 1022, the unclogging head 5 mechanically unblocks the water outlet 1022. After the water outlet 1022 is unblocked, the water outlet 1022 can drain water normally, and the hydraulic pressure in the second cavity 1012 gradually decreases. When it decreases below the opening threshold, the opening component 4 is closed, and then the elastic pad 3 is reset to drive the unclogging head 5 to move upward away from the water outlet 1022, and the sprinkler 1000 can operate normally.

[0046] The thickness of the middle portion of the elastic pad 3 is greater than the thickness of the periphery, which can ensure the structural strength of the connection between the middle portion and the dredging head 5 on the basis of reducing the overall mass of the elastic pad 3 .

[0047] Installing the elastic pad 3 between the shell 1 and the cover 2 can not only improve the stability of the installation of the elastic pad 3, but also serve as a sealing pad to improve the sealing performance between the shell 1 and the cover 2, thereby ensuring the relative independence of the first cavity 1011 and the second cavity 1012.

[0048] The drip irrigation emitter 1000 of the embodiment of the present invention realizes the connection or disconnection between the first cavity 1011 and the second cavity 1012 by setting the opening component 4, and realizes the downward protrusion or reset of the middle part of the elastic pad 3 through the connection and disconnection of the first cavity 1011 and the second cavity 1012, thereby driving the clearing head 5 to move downward or upward to mechanically clear the water outlet 1022, thereby reducing the risk of blockage of the emitter 1000.

[0049] In some embodiments, the elastic pad 3 has a connecting port 31, which is used to connect the first cavity 1011 and the second cavity 1012. The opening component 4 is located at the connecting port 31 to open and close the connecting port 31. The opening component 4 includes a connecting shaft 41, a first elastic member 42 and an opening and closing plate 43. The connecting shaft 41 is located between the opening and closing plate 43 and the elastic pad 3. The opening and closing plate 43 can be rotated relative to the elastic pad 3 to open and close the connecting port 31. One end of the first elastic member 42 abuts against the opening and closing plate 43, and the other end of the first elastic member 42 abuts against the cover body 2.

[0050] Specifically, Figure 1 As shown, the connecting port 31 is opened on the elastic pad 3, and the connecting port 31 passes through the elastic pad 3. The opening component 4 is located at the connecting port 31 to realize the opening and closing of the opening, thereby realizing the connection and disconnection of the first cavity 1011 and the second cavity 1012.

[0051] The connecting shaft 41 is inserted into the elastic pad 3, and the opening and closing piece 43 is sleeved on the connecting shaft 41. The opening and closing piece 43 swings relative to the elastic pad 3 with the connecting shaft 41 as the rotation axis 128. One end of the first elastic member 42 is connected to the upper end of the opening and closing piece 43, and the other end of the first elastic member 42 is connected to the cover body 2.

[0052] It should be noted that, when the pressure in the second cavity 1012 is greater than the elastic resistance of the first elastic member 42, the opening and closing piece 43 is lifted up by the pressure in the second cavity 1012 and swings relative to the elastic pad 3 to realize the opening and closing of the connecting port 31; conversely, when the pressure in the second cavity 1012 is less than or equal to the elastic resistance of the first elastic member 42, the opening and closing piece 43 fits with the elastic pad 3 under the elastic force of the first elastic member 42 to seal the connecting port 31, thereby realizing the isolation between the first cavity 1011 and the second cavity 1012.

[0053] It should be noted that the opening and closing threshold of the opening and closing piece 43 can be adjusted by replacing the first elastic piece with different elastic resistance. The greater the elastic resistance of the first elastic piece, the greater the opening and closing threshold of the opening and closing piece 43. Conversely, the smaller the elastic resistance of the first elastic piece, the smaller the opening and closing threshold of the opening and closing piece 43.

[0054] The present invention can realize the opening and closing of the opening and closing piece 43 by using the first elastic piece, realize the connection and disconnection of the first cavity 1011 and the second cavity 1012, and can also adjust the elastic resistance of the first elastic member 42 to realize different opening and closing thresholds to meet different usage scenarios. And compared with the electric control opening, the opening and closing piece 43 in the present invention is more stable and reduces the manufacturing cost when realizing the connection and disconnection of the first cavity 1011 and the second cavity 1012 by using the opening and closing piece 43.

[0055] In some embodiments, the drip irrigation emitter 1000 further includes a second elastic member 6 , which is located in the first cavity 1011 , one end of the second elastic member 6 is connected to the cover 2 , and the other end of the second elastic member 6 is connected to the elastic pad 3 .

[0056] Specifically, Figure 1 As shown, the upper end of the second elastic member 6 is connected to the cover body 2 , and the other end of the lower end of the second elastic member 6 is connected to the elastic pad 3 . The second elastic member 6 can realize the rapid reset of the elastic pad 3 .

[0057] In some embodiments, the elastic pad 3 has a guide portion 32 and a mounting portion 33, the guide portion 32 is located in the first cavity 1011, and extends in the up-down direction. The second elastic member 6 is sleeved on the guide portion 32, and the mounting portion 33 is located in the second cavity 1012, and extends in the up-down direction. The mounting portion 33 is connected to the dredging head 5.

[0058] Specifically, Figure 1 As shown, the guide portion 32 extends in the up-down direction, and the second elastic member 6 is sleeved on the outside of the guide portion 32. The guide portion 32 can provide guidance for the elastic pad 3 during the up-down movement of the elastic pad 3, and the guide portion 32 can also prevent the second elastic member 6 from being misplaced, thereby ensuring the stability of the resetting of the elastic pad 3.

[0059] The mounting portion 33 is a connecting flange, and the mounting portion 33 is located in the second cavity 1012 . The upper end of the dredging head 5 is detachably connected to the mounting portion 33 . The installation stability and efficiency of the dredging head 5 can be improved by providing the mounting portion 33 .

[0060] In some embodiments, the unclogging head 5 is rotatable relative to the elastic pad 3 .

[0061] Specifically, Figure 3 and Figure 4 As shown, a rotary joint 17 is provided between the unclogging head 5 and the mounting portion 33, a flow channel is provided inside the unclogging head 5, a plurality of spray holes 51 are provided on the unclogging head 5, the plurality of spray holes 51 are arranged at intervals along the length direction of the unclogging head 5, the axis of the spray hole 51 is eccentrically arranged with respect to the axis of the unclogging head 5, the flow channel connects the first cavity 1011 and the second cavity 1012, and the spray hole 51 connects the flow channel and the second cavity 1012.

[0062] like Fig. 9 As shown, according to the finite element analysis results, along with the rotation of the dredging head 5, the high-pressure jet generates a vortex, and the vortex fills the entire water outlet 1022, the vortex drives the soil in the water outlet 1022 to roll, and the rolling soil cuts and impacts the inner surface of the water outlet 1022, which can further remove the soil on the inner surface of the water outlet 1022.

[0063] It should be noted that by setting up multiple spray holes 51, multi-angle spraying can be achieved, which can improve the cleaning effect of the unclogging head 5. There is a preset angle between the axis of the spray hole 51 and the axis of the unclogging head 5. The sprayed water flow generates a reverse thrust to form a torque, so that the water jet recoil force generated by the high-pressure water ejected from each spray hole 51 interacts with each other to generate a rotational torque that is greater than the friction torque of the unclogging head 5, thereby causing the unclogging head 5 to rotate, and water flows out from each spray hole 51 to form a high-speed jet, which drives the unclogging head 5 to rotate and realize the cleaning operation, and the high-pressure water ejected from the spray hole 51 forms a spiral trajectory along the inner surface of the pipe, covering and flushing the inner surface of the water outlet 1022, thereby affecting the cleaning efficiency. During the rotation of the unclogging head 5, the ejected high-pressure water can converge into a conical jet, covering the dirt inside the water outlet 1022, impacting and peeling it off, thereby improving the cleaning rate and efficiency of the water outlet 1022.

[0064] Furthermore, the water in the first cavity 1011 can be discharged into the second cavity 1012 by using the spray hole 51 and the flow channel, thereby preventing excessive accumulation of water in the first cavity 1011 .

[0065] like Figures 4 to 8 As shown, the drip irrigation device of the embodiment of the present invention includes a mixing box 8, a delivery pump 13, a drip irrigation belt 15 and a plurality of emitters 1000. The delivery pump 13 is connected to the mixing box 8, and the mixing box 8 is used to stir the material. The drip irrigation belt 15 is connected to the outlet of the delivery pump 13. The plurality of emitters 1000 are respectively connected to the drip irrigation belt 15.

[0067] Optionally, the drip irrigation device further comprises a storage box 14 mounted on the upper portion of the base 7 and a connecting assembly 9 mounted on the upper portion of the base 7, wherein the connecting assembly 9 comprises a filtering component 10 disposed on the upper portion of the base 7.

[0068] A stirring assembly 12 is provided on the upper part of the base 7, and the input end of the delivery pump 13 is connected to the stirring box 8 through a connecting pipe.

[0070] The bottom of the limit block 108 is fitted with the outer side of the filter plate 102, and the sealing ring 103 is set in the gap between the filter plate 102 and the processing box 101. Through the cooperation of the processing box 101, the filter plate 102, and the sealing ring 103, the water flowing to the mixing box 8 can be filtered, thereby preventing the solid impurities in the water from affecting the mixing of materials in the mixing box 8 and reducing the risk of clogging of the drip irrigation head. At the same time, through the cooperation of the first sliding rod 105, the first sliding block 106, the third elastic member 107, and the limit block 108, it is convenient to manually disassemble the filter plate 102, thereby facilitating manual cleaning of the filter plate 102 and ensuring the normal use of the device.

[0071] Furthermore, the upper portion of the positioning block 1010 is installed with the filter plate 102. Through the cooperation of the positioning block 1010 and the positioning groove 109, the connection relationship between the filter plate 102 and the processing box 101 can be made more stable, thereby making the filter plate 102 more stable during use.

[0072] The positioning block 1010 and the magnet 11 are repelling magnets 11. When the filter plate 102 needs to be disassembled, it is only necessary to manually push the limit block 108 to separate the limit block 108 from the outer side of the filter plate 102. Since the positioning block 1010 and the magnet 11 are repelling magnets 11, the filter plate 102 can be popped up under the action of repulsive force, and then the filter plate 102 can be manually taken out upward, thereby facilitating manual cleaning of the filter plate 102 and ensuring normal use of the device.
