A novel water pipe support mechanism for greenhouse sprinkler irrigation machines

Abstract

This utility model provides a novel water pipe support mechanism for a greenhouse sprinkler irrigation machine, including a support frame, a water pipe support plate, multiple abutment plates, and multiple sealing plates. A support cylinder is located on one side of the support frame. Inside the support cylinder is a transmission component for moving the multiple abutment plates closer together and further apart. When the multiple abutment plates separate, they abut and fix the water pipe support plate; when the multiple abutment plates come together, they release the abutment and fixation. A support rod is bolted to the side of the support frame away from the support cylinder. The mechanism is designed with an upward tilt angle. After the water pipe falls in, it automatically slides to the outer corner of the water pipe support plate. The deformation caused by the accumulated length of the water pipe is limited by gravity, extending only outwards and downwards, and cannot bend upwards, completely preventing it from coming off. Also designed with an upward tilt angle, after the water pipe falls in, it can slide to the outer corner of the support roller and remain in this position throughout the entire movement, ensuring stable support.

Description

Technical Field

[0001] This utility model relates to the field of irrigation technology, and in particular to a novel water pipe support mechanism for greenhouse sprinkler irrigation machines. Background Technology

[0002] In a precision irrigation system for greenhouses, the water pipe support mechanism is a core component that ensures the stable operation of the sprinkler irrigation machine. It supports the weight of the pipe through the water pipe support plate and relies on the support rollers to realize the synchronous movement of the sprinkler trolley and the water pipe, which directly affects the uniformity of irrigation and the life of the equipment.

[0003] Currently, most water pipe supports for sprinkler irrigation machines from different brands at home and abroad adopt horizontal support schemes, including different forms such as flat plate supports and round pipe supports. After the water pipe is placed on the support, it is generally stationary at 1 / 3 of the support. Part of the support is deformed by gravity, causing the water pipe to tilt inward, increasing the risk of the water pipe coming off the hook. In addition, in traditional support mechanisms, the water pipe support and bracket, and the support roller and axle are mostly fixed by bolts, nuts and other threaded connections. In greenhouse environments with high humidity, residual moisture can easily cause fasteners to rust and get stuck. Disassembly requires repeated rust removal and the use of special tools such as wrenches, which takes a long time.

[0004] Therefore, it is necessary to provide a new type of greenhouse sprinkler irrigation machine water pipe support mechanism to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a novel water pipe support mechanism for greenhouse sprinkler irrigation machines.

[0006] This utility model provides a novel water pipe support mechanism for a greenhouse sprinkler irrigation machine, comprising a support frame, a water pipe support plate, multiple abutment plates, and multiple sealing plates. A support cylinder is located on one side of the support frame. Inside the support cylinder is a transmission component for moving the multiple abutment plates closer together and further apart. When the multiple abutment plates separate, they abut and fix the water pipe support plate; when the multiple abutment plates come together, they release the abutment and fixation. A support rod is bolted to the side of the support frame away from the support cylinder for further fixing. One end of the receiving rod is fixedly connected to the snap-fit ​​base. The supporting roller is rotated and sleeved on the outer circumference of the fixed receiving rod. The snap-fit ​​base is equipped with a drive component for driving multiple sealing plates to move closer and further apart. When the multiple sealing plates move apart, they seal the supporting roller. When the multiple sealing plates move further apart, they release the seal on the supporting roller. Angle 1 is formed between the water pipe support plate and one side of the receiving frame, and angle 2 is formed between the supporting roller and the other side of the receiving frame. Two water pipes are placed at angle 1 and angle 2 respectively.

[0007] Preferably, the transmission assembly includes a lead screw motor, a guide lead screw, a lead screw slider, and a connecting column. Multiple abutment slots are respectively opened on the outer circumference of the receiving cylinder. The lead screw motor is located on one side of the inner wall of the receiving cylinder, and the connecting column is located on the other side of the inner wall of the receiving cylinder. The output end of the lead screw motor is connected to one end of the guide lead screw, and the other end of the guide lead screw is rotatably connected to the connecting column. The outer surface of the guide lead screw is threadedly connected to the lead screw slider. An active transmission assembly is provided between the lead screw slider and the abutment plate, and an auxiliary transmission assembly is provided between the connecting column and the abutment plate.

[0008] Preferably, the active transmission assembly includes multiple hinged bases 1, multiple transmission plates, and multiple hinged bases 2. The multiple hinged bases 1 are arranged in a circumferential array on the outer side of the lead screw slider. The multiple hinged bases 2 are fixedly connected to the edges of the multiple abutment plates on the same side. The multiple hinged bases 1 and the multiple hinged bases 2 are rotatably connected to the multiple transmission plates.

[0009] Preferably, the auxiliary transmission assembly includes multiple auxiliary base 1, multiple auxiliary transmission plates and multiple auxiliary base 2. The multiple auxiliary base 1 are arranged in a circumferential array on the outer side of the connecting column. The multiple auxiliary base 2 are fixedly connected to the edge of the multiple abutment plates on the side close to each other, away from the multiple hinge base 2. The multiple auxiliary base 1 and the multiple auxiliary base 2 are rotatably connected to the multiple auxiliary transmission plates.

[0010] Preferably, the drive assembly includes a servo motor, a servo motor shaft, a drive gear, a driven gear, and a driven gear shaft. A meshing groove is provided inside the snap-fit ​​base. The servo motor is embedded inside the snap-fit ​​base. The output end of the servo motor is connected to one end of the servo motor shaft. The other end of the servo motor shaft is rotatably connected to the side wall of the meshing groove. A drive gear is fitted onto the outer surface of the servo motor shaft. A driven gear shaft is rotatably positioned between the inner walls on both sides of the meshing groove. A driven gear is rotatably fitted onto the outer surface of the driven gear shaft. The driven gear meshes with the drive gear. A drive assembly is provided between the driven gear and multiple sealing plates.

[0011] Preferably, the drive assembly includes multiple guide plates and multiple guide shafts. Multiple arc-shaped guide grooves are arranged in a circular array on the driven gear. Multiple guide grooves are arranged in a circular array on the outer side of the snap-fit ​​base. The multiple guide grooves are connected to the meshing grooves. Multiple guide plates are fixedly connected to the side of multiple sealing plates that are close to each other. The multiple guide plates are slidably connected inside the multiple guide grooves. Multiple guide shafts are fixedly connected to the end of the multiple guide plates that is away from the multiple sealing plates. The multiple guide shafts slide through the multiple guide grooves and are slidably connected inside the multiple arc-shaped guide grooves.

[0012] Compared with related technologies, the novel greenhouse sprinkler irrigation machine water pipe support mechanism provided by this utility model has the following beneficial effects: By setting it to an upward tilt angle, the water pipe will automatically slide to the outer corner of the water pipe support plate after falling in. The deformation caused by the accumulation of the water pipe's length is limited by gravity, extending only outward and downward, and cannot bend upward, thus completely preventing it from coming out. Similarly, by designing it to have an upward tilt angle, the water pipe can slide to the outer corner of the supporting roller after falling in, and will always remain in this position throughout the entire movement, ensuring stable support.

[0013] The transmission assembly moves multiple contact plates together and apart. When the contact plates separate, they quickly and firmly secure the water pipe support plate, ensuring it remains stable and does not shift during sprinkler operation. When the contact plates move together, they can be released directly without disassembling complex connection structures, significantly simplifying the water pipe support plate disassembly process and saving replacement time and manpower. The drive assembly moves multiple sealing plates together and apart. When the sealing plates separate, they reliably seal the supporting rollers, preventing them from shifting or falling off due to vibration or stress during sprinkler operation, ensuring stable roller operation. When the sealing plates move apart, they quickly release the roller's restraint without disassembling related components, making the removal and replacement of the supporting rollers more convenient and reducing maintenance difficulty.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please refer to the following: Figure 1-7 ,in, Figure 1 A schematic diagram of a preferred embodiment of a novel greenhouse sprinkler irrigation machine water pipe support mechanism provided by this utility model; Figure 2 for Figure 1 The diagram shows the structural schematic of the support frame; Figure 3 for Figure 1 The diagram shows the structure of the water pipe support plate.

[0018] In the specific implementation process, such as Figure 1-7As shown, the assembly includes a receiving frame 1, a water pipe support plate 2, multiple abutment plates 8, and multiple sealing plates 901. A receiving cylinder 5 is located on one side of the receiving frame 1. Inside the receiving cylinder 5 is a transmission assembly for moving the multiple abutment plates 8 closer together and further apart. When the multiple abutment plates 8 separate, they abut and fix the water pipe support plate 2; when the multiple abutment plates 8 come together, they release the abutment and fixation on the water pipe support plate 2. A receiving rod 4 is bolted to the side of the receiving frame 1 away from the receiving cylinder 5. One end of the fixed receiving rod 4 is fixedly connected to a clamping base. The base 9, with the supporting roller 3 rotatably mounted on the outer circumference of the fixed supporting rod 4, has a drive assembly inside the base 9 for moving multiple sealing plates 901 closer together and further apart. When the multiple sealing plates 901 are apart, they seal the supporting roller 3; when the multiple sealing plates 901 are far apart, they release the seal on the supporting roller 3. An angle 1 is formed between the water pipe support plate 2 and one side of the supporting frame 1, and an angle 2 is formed between the supporting roller 3 and the other side of the supporting frame 1.

The active transmission assembly includes multiple hinged bases 605, multiple transmission plates 603, and multiple hinged bases 604. Multiple hinged bases 605 are arranged in a circumferential array on the outer side of the lead screw slider 602. Multiple hinged bases 604 are fixedly connected to the edge of the multiple abutment plates 8 on the same side. Multiple transmission plates 603 are rotatably connected between the multiple hinged bases 605 and the multiple hinged bases 604. The auxiliary transmission assembly includes multiple auxiliary bases 702, multiple auxiliary transmission plates 701 and multiple auxiliary bases 703. Multiple auxiliary bases 702 are arranged in a circumferential array on the outer side of the connecting column 7. Multiple auxiliary bases 703 are fixedly connected to the edge of the multiple abutment plates 8 on the same side away from the multiple hinged bases 604. Multiple auxiliary transmission plates 701 are rotatably connected between the multiple auxiliary bases 702 and the multiple auxiliary bases 703.

[0020] The water supply pipes are made of high-density polyethylene. Due to the high coefficient of thermal expansion of high-density polyethylene, and the large temperature difference at the top of the greenhouse, it is not affected by temperature changes or fatigue deformation.

[0021] In the specific implementation process, such as Figure 5-7As shown, the drive assembly includes a servo motor 908, a servo motor shaft 910, a drive gear 909, a driven gear 905, and a driven gear shaft 907. A meshing groove 911 is provided inside the locking base 9. The servo motor 908 is embedded inside the locking base 9. The output end of the servo motor 908 is connected to one end of the servo motor shaft 910. The other end of the servo motor shaft 910 is rotatably connected to the side wall of the meshing groove 911. The drive gear 909 is sleeved on the outer surface of the servo motor shaft 910. The driven gear shaft 907 is rotatably positioned between the inner walls of both sides of the meshing groove 911. The driven gear 905 is rotatably sleeved on the outer surface of the driven gear shaft 907. The driven gear 905 meshes with the drive gear 909. A drive assembly is provided between 05 and multiple sealing plates 901. The drive assembly includes multiple guide plates 902 and multiple guide shafts 903. Multiple arc-shaped guide grooves 906 are arranged in a circular array on the driven gear 905. Multiple guide grooves 904 are arranged in a circular array on the outer side of the snap-fit ​​base 9. The multiple guide grooves 904 are connected to the meshing grooves 911. Multiple guide plates 902 are fixedly connected to the side of the multiple sealing plates 901 respectively. The multiple guide plates 902 are slidably connected inside the multiple guide grooves 904. Multiple guide shafts 903 are fixedly connected to the end of the multiple guide plates 902 away from the multiple sealing plates 901 respectively. The multiple guide shafts 903 pass through the multiple guide grooves 904 and are slidably connected inside the multiple arc-shaped guide grooves 906.

[0022] The working principle of this utility model is as follows: The starting screw motor 6 drives the guide screw 601 to move the screw slider 602 toward the connecting column 7. Then, the screw slider 602 pushes multiple transmission plates 603 to rotate out of phase. As a result, the multiple transmission plates 603 push multiple abutment plates 8 through multiple abutment grooves 501 to abut against the reserved holes of the water pipe support plate 2, thereby abutting and fixing the water pipe support plate 2. By reversing the above operation, the multiple abutment plates 8 can enter the receiving cylinder 5 through the multiple abutment grooves 501 to release the abutment and fixing of the water pipe support plate 2, which facilitates the quick replacement of the water pipe support plate 2.

[0023] The supporting roller 3 is rotated and fitted onto the outer surface of the receiving rod 4. The servo motor 908 is started to drive the servo motor shaft 910 to rotate the drive gear 909. The drive gear 909 then meshes with and drives the driven gear 905 to rotate. The driven gear 905 then pushes multiple guide shafts 903 to rotate away from each other through multiple arc-shaped guide grooves 906. The multiple guide shafts 903 then push multiple guide plates 902 to move away from each other along multiple guide grooves 904. As a result, the multiple guide plates 902 push multiple sealing plates 901 to move away from each other, and the multiple sealing plates 901 then seal the supporting roller 3 to prevent it from falling off. By reversing the above operation, the multiple guide plates 902 can move along multiple guide grooves 904 to bring the multiple sealing plates 901 closer together to release the seal on the supporting roller 3, making it easier to remove the supporting roller 3.

[0024] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
