Description

Technical Field

[0001] This utility model relates to the field of irrigation sprinkler technology, and in particular to a micro-sprinkler fixing device for precision drip irrigation in greenhouses. Background Technology

[0002] In drip irrigation systems, micro-sprinklers are a key component, delivering water evenly to the roots of crops in the form of tiny droplets to meet their growth needs. However, in practical applications, securing the micro-sprinklers becomes a problem. If not securely fixed, the micro-sprinklers are prone to displacement or falling off, leading to uneven irrigation or system failure. Furthermore, the complex environment inside greenhouses, including temperature and humidity variations, as well as changes in crop growth patterns, all pose challenges to the secure fixing of micro-sprinklers.

[0003] Currently, there are some micro-sprinkler fixing devices on the market, but most of these devices suffer from problems such as limited fixing methods, poor adaptability, and complex installation, making it difficult to meet the needs of different environments and crop growth stages within greenhouses. Therefore, developing a micro-sprinkler fixing device that is simple in structure, easy to install, firmly fixed, and adaptable to the complex environment of greenhouses has significant practical significance and application value.

[0004] Chinese utility model patent application number CN215655971U discloses a fixed irrigation sprinkler head with pressure regulation function. Its features include a pressure regulating device with a cavity groove at its upper end. A sealing ring is detachably connected to the opening of the cavity groove. A piston is movably connected inside the sealing ring. A sliding hook block is fixedly connected to the side wall of the piston rod, and a pressure plug is fixedly connected to the bottom of the piston rod. Clip blocks are movably connected to the left and right side walls of the cavity groove. The pressure plug changes the water flow rate by pressing down and pulling up the piston rod, thereby changing the water pressure. Different pressure regulation functions are achieved by fixing the nozzle with sliding hook blocks and clip blocks at different positions. A threaded rod is connected to the fixing ring; rotating the nut tightens the thread to secure the irrigation sprinkler head, making it stable and preventing loosening.

[0005] In the above-mentioned device, the nozzle is usually fixed by a threaded connection. However, when the working time is too long or under water pressure, the threaded connection between the nozzle and the fixing ring may loosen, resulting in an unstable connection.

[0006] To address this, a micro-sprinkler fixing device for precision drip irrigation in greenhouses is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a micro-sprinkler fixing device for precision drip irrigation in greenhouses, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a micro-sprinkler fixing device for precision drip irrigation in greenhouses, comprising a fixing sleeve and a sprinkler head, wherein the sprinkler head is threadedly connected to the fixing sleeve. The fixing sleeve contains a clamping component for clamping and fixing the bottom end of the sprinkler head. An auxiliary component for driving the clamping component is located on the side of the clamping component away from the bottom end of the sprinkler head. The auxiliary component is pultrusively connected to the clamping component. A disassembly component for releasing the clamping state is slidably fitted at the top of the auxiliary component. The disassembly component is pultrusively connected to the upper end of the sprinkler head. When the sprinkler head rotates and engages with the threaded fixing sleeve, the disassembly component drives the clamping component to clamp and fix the bottom end of the sprinkler head, improving the stability of the sprinkler head connection. When the disassembly component disengages from the sprinkler head, the clamping components move away from each other, releasing the clamping of the bottom end of the sprinkler head.

[0009] A rubber pad is fixed at one end of each clamping component that is close to the other. When the clamping components clamp the bottom of the nozzle, the rubber pad fits tightly against the bottom of the nozzle, increasing the rotational friction of the bottom of the nozzle and improving the stability of the connection. The rubber pad also seals the bottom of the nozzle, preventing water leakage at the connection between the nozzle and the fixing sleeve.

[0010] Preferably, one end of the fixing sleeve has an installation port, the inner wall of the installation port has a threaded groove, a partition is fixed to the inner wall of the fixing sleeve, the clamping assembly is disposed inside the partition, and the clamping assembly is elastically connected to the inner wall of the partition.

[0011] Preferably, a first gear is fixed to the outer side of the upper end of the nozzle, and a threaded block is fixed to the outer side of the middle part of the nozzle, the threaded block being threadedly engaged with the threaded groove.

[0012] Preferably, the auxiliary component includes a rotating rod, which is vertically rotatably connected to the side of the partition away from the clamping component. A second gear is fixed at the bottom end of the rotating rod, which meshes with the clamping component for transmission. The top end of the rotating rod is slidably engaged with the disassembly component.

[0013] Preferably, the disassembly assembly includes a pull rod, the lower end of which has a vertically formed second sliding groove, the upper end of which is slidably connected to the second sliding groove, the upper end of which is elastically connected to the bottom end of the second sliding groove, a guide block fixed to the outer side of the upper end of the rotating rod, a guide groove vertically formed on the inner sidewall of the second sliding groove, the guide block slidingly engaging with the guide groove, a third gear fixed to the outer side of the pull rod, the third gear meshing with the first gear, and a pull block rotatably connected to the top end of the pull rod.

[0014] Preferably, a first sliding groove is horizontally formed in the partition, the first sliding grooves are arranged opposite each other, the clamping assembly includes a clamping block, the clamping block is slidably engaged with the first sliding groove, the side of the clamping block that is far apart from each other is elastically connected to the bottom end of the first sliding groove, and a rack is horizontally fixed on the side of the clamping block that is far apart from each other, the rack meshing with a second gear.

[0015] Preferably, a rubber pad is fixed on one side of the clamping blocks that are close to each other, the middle part of the rubber pad is in contact with the bottom end of the nozzle, and the two ends of the rubber pad 401 are in contact with each other.

[0016] The beneficial effects of this utility model are:

[0017] This invention incorporates clamping blocks within the fixed sleeve. When the nozzle is threadedly connected to the fixed sleeve, the nozzle, through gear transmission, drives the clamping blocks to move closer together, clamping and fixing the bottom end of the nozzle. This prevents the threaded connection between the nozzle and the fixed sleeve from loosening due to prolonged operation or water pressure, thus improving the stability of the nozzle connection.

[0018] This invention uses rubber pads on the clamping blocks. When the clamping blocks clamp and fix the bottom end of the nozzle, the rubber pads squeeze against each other, making the rubber pads fit tightly against the bottom end of the nozzle. This increases the rotational friction at the bottom end of the nozzle, improves the stability of the connection, and the mutual squeezing of the rubber pads seals the bottom end of the nozzle, preventing water leakage at the connection between the nozzle and the fixing sleeve.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0029] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

[0030] like Figures 1 to 7As shown in the specific embodiment of this utility model, a micro-sprinkler fixing device for precision drip irrigation in greenhouses includes a fixing sleeve 1 and a sprinkler head 2. The sprinkler head 2 is threadedly connected to the fixing sleeve 1. A clamping component for clamping and fixing the bottom end of the sprinkler head 2 is provided inside the fixing sleeve 1. An auxiliary component for driving the clamping component is provided on the side of the clamping component away from the bottom end of the sprinkler head 2. The auxiliary component is pultrusively connected to the clamping component. A disassembly component for releasing the clamping state is slidably fitted at the top of the auxiliary component. The disassembly component is pultrusively connected to the upper end of the sprinkler head 2. When the sprinkler head 2 rotates and engages with the threaded fixing sleeve 1, the disassembly component drives the clamping component to clamp and fix the bottom end of the sprinkler head 2, improving the stability of the sprinkler head 2 connection. When the disassembly component disengages from the sprinkler head 2, the clamping components move away from each other, releasing the clamping of the bottom end of the sprinkler head 2.

[0031] A rubber pad 401 is fixed at one end of the clamping assembly that is close to the other. When the clamping assembly clamps the bottom end of the nozzle 2, the rubber pad 401 fits tightly with the bottom end of the nozzle 2, which increases the rotational friction of the bottom end of the nozzle 2 and improves the stability of the connection. The rubber pad 401 also seals the bottom end of the nozzle 2 to prevent water leakage at the connection between the nozzle 2 and the fixing sleeve 1.

[0032] In actual use, initially, the clamping components are far apart. When nozzle 2 needs to be installed, the nozzle 2 is rotated to connect with the fixed sleeve 1 via a thread. At the same time, the nozzle 2 rotates, causing the disassembly component to rotate, which in turn causes the auxiliary component to rotate, bringing the clamping components closer together until the nozzle 2 and fixed sleeve 1 are fully engaged. The clamping components simultaneously clamp and fix the bottom end of the nozzle 2, preventing the threaded connection between the nozzle 2 and fixed sleeve 1 from loosening due to prolonged working time or water pressure. This improves the stability of the connection. Furthermore, the rubber pads 401 are pressed against each other, and the clamping components apply pressure to the nozzle. The bottom of nozzle 2 is sealed to prevent water leakage at the connection between nozzle 2 and fixing sleeve 1. During drip irrigation, rubber pad 401 fits tightly against the bottom of nozzle 2, increasing the rotational friction at the bottom of nozzle 2 and improving the stability of the connection. The rubber pads 401 also press against each other to seal the bottom of nozzle 2, preventing water leakage at the connection between nozzle 2 and fixing sleeve 1. When nozzle 2 needs to be replaced, pull the disassembly assembly upward to disengage it from nozzle 2, move the clamping assemblies away from each other, release the clamp on the bottom of nozzle 2, rotate nozzle 2 to release the threaded connection, and remove nozzle 2.

[0033] As one embodiment of this utility model, such as Figures 1-3 , Figures 5-6 As shown, one end of the fixing sleeve 1 has an installation port 101, and the inner wall of the installation port 101 has a threaded groove 102. A partition 3 is fixed to the inner wall of the fixing sleeve 1, and the clamping assembly is disposed inside the partition 3. The clamping assembly is elastically connected to the inner wall of the partition 3.

[0034] As one embodiment of this utility model, such as Figures 1-3 , Figure 7 As shown, a first gear 202 is fixed on the outer side of the upper end of the nozzle 2, and a threaded block 201 is fixed on the outer side of the middle part of the nozzle 2. The threaded block 201 is threadedly engaged with the threaded groove 102.

[0035] As one embodiment of this utility model, such as Figures 1-2 , Figures 4-6 As shown, the auxiliary component includes a rotating rod 5, which is vertically rotatably connected to the side of the partition 3 away from the clamping component. A second gear 501 is fixed at the bottom of the rotating rod 5, and the second gear 501 meshes with the clamping component for transmission. The top of the rotating rod 5 is slidably engaged with the disassembly component. When the rotating rod 5 rotates, it drives the second gear 501 to rotate, causing the clamping components to move closer to each other, so that the clamping components clamp and fix the bottom of the nozzle 2, thereby improving the stability of the connection.

[0036] As one embodiment of this utility model, such as Figures 1-2 , Figures 4-6 As shown, the disassembly assembly includes a pull rod 6, with a second sliding groove 602 vertically formed at the lower end of the pull rod 6. The upper end of the rotating rod 5 is slidably connected to the second sliding groove 602, and the upper end of the rotating rod 5 is elastically connected to the bottom end of the second sliding groove 602. A guide block 502 is fixed to the outer side of the upper end of the rotating rod 5. A guide groove 603 is vertically formed on the inner sidewall of the second sliding groove 602, and the guide block 502 is slidably engaged with the guide groove 603. A third gear 601 is fixed to the outer side of the pull rod 6, and the third gear 601 meshes with the first gear 202. A pull block 7 is rotatably connected to the top end of the pull rod 6.

[0037] In actual use, initially, the clamping components are far apart. When it is necessary to install the nozzle 2, align the bottom end of the nozzle 2 with the mounting port 101, and mesh the first gear 202 and the third gear 601. Rotate the nozzle 2 to connect it to the mounting port 101. At the same time, the nozzle 2 rotates, causing the first gear 202 to rotate, which in turn causes the third gear 601 to rotate, which in turn causes the rotating rod 5 to rotate, which in turn causes the second gear 501 to rotate. This causes the clamping components to move closer together, clamping and fixing the bottom end of the nozzle 2. This improves the stability of the nozzle 2. When the nozzle 2 needs to be replaced, pull the pull block 7 upward, which moves the pull rod 6 upward, causing the rotating rod 5 to move downward relative to the pull rod 6 until the third gear 601 disengages from the first gear 202. The clamping components move away from each other under the elastic action, releasing the clamping and fixing of the bottom end of the nozzle 2. At the same time, the clamping components drive the second gear 501 to rotate, which drives the rotating rod 5 to rotate, which drives the pull rod 6 to rotate. Then, rotate the nozzle 2 in the opposite direction to release the threaded connection between the nozzle 2 and the mounting port 101, and remove the nozzle 2.

[0038] As one embodiment of this utility model, such as Figures 5-6 As shown, a first sliding groove 301 is horizontally opened in the partition 3. The first sliding groove 301 is arranged opposite to each other. The clamping assembly includes a clamping block 4. The clamping block 4 is slidably engaged with the first sliding groove 301. The side of the clamping block 4 that is far apart from each other is elastically connected to the bottom end of the first sliding groove 301. A rack 402 is horizontally fixed on the side of the clamping block 4 that is far apart from each other. The rack 402 meshes with the second gear 501. A rubber pad 401 is fixed on the side of the clamping block 4 that is close to each other. The middle part of the rubber pad 401 is in contact with the bottom end of the nozzle 2. The two ends of the rubber pad 401 are in contact with each other.

[0039] In actual use, initially, the clamping blocks 4 are far apart. When the nozzle 2 needs to be installed, the nozzle 2 is rotated, which drives the rotating rod 5 to rotate, causing the rack 402 to move outward from the first sliding groove 301, and causing the clamping blocks 4 to move closer together to clamp and fix the bottom end of the nozzle 2. The rubber pads 401 are pressed against each other, making the rubber pads 401 and the bottom end of the nozzle 2 fit tightly together, increasing the rotational friction of the bottom end of the nozzle 2, improving the stability of the connection, and the rubber pads 401 are pressed against each other to seal the bottom end of the nozzle 2, preventing water leakage at the connection between the nozzle 2 and the fixing sleeve 1. When the nozzle 2 needs to be replaced, the pull block 7 is pulled upward. Under the action of elasticity, the clamping blocks 4 move away from each other, releasing the clamping and fixing of the bottom end of the nozzle 2, making it easy to reverse the nozzle 2 and disengage it from the installation port 101.

[0040] Working principle: In the initial state, the clamping blocks 4 are far apart, and the upper end of the rotating rod 5 is close to the bottom end of the second sliding groove 602. When the nozzle 2 needs to be installed, the bottom end of the nozzle 2 is aligned with the mounting port 101, and the first gear 202 and the third gear 601 are meshed. The nozzle 2 is rotated and threadedly connected to the mounting port 101. At the same time, the nozzle 2 rotates, which drives the third gear 601 to rotate, which drives the rotating rod 5 to rotate, which drives the second gear 501 to rotate, which drives the clamping blocks 4 to move closer together. The clamping blocks 4 clamp and fix the bottom end of the nozzle 2, which improves the stability of the nozzle 2. When the clamping block 4 clamps and fixes the bottom end of the nozzle 2, the rubber pads 401 are squeezed against each other, making the rubber pads 401 fit tightly against the bottom end of the nozzle 2, increasing the rotational friction of the bottom end of the nozzle 2, improving the stability of the connection, and the rubber pads 401 squeeze against each other to seal the bottom end of the nozzle 2, preventing water leakage at the connection between the nozzle 2 and the fixing sleeve 1; when the nozzle 2 needs to be replaced, pull the pull block 7 upward, and under the action of elasticity, the clamping blocks 4 move away from each other, releasing the clamping and fixing of the bottom end of the nozzle 2, reversing the nozzle 2 and the mounting port 101 to separate them, and removing the nozzle 2.
