Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation technology, and more specifically, to a protective support frame for agricultural water supply pipes. Background Technology

[0002] The protective support frame for agricultural irrigation water supply pipes is an important facility used to fix, support and protect irrigation pipes. Its function is to prevent the pipes from shifting, deforming or being damaged due to gravity, external forces or environmental factors (such as temperature changes, soil settlement, mechanical vibration, etc.).

[0003] In the prior art, such as the "Protective Support Frame for Farmland Irrigation Water Supply Pipe" in Chinese Patent Publication No. CN220727355U, a bidirectional rotating screw is set between the base plate and the mounting plate, and several rotating rods are used to achieve fixed support for the water supply pipe. At the same time, the angle of the water pipe can be bent according to the needs of use, so as to facilitate irrigation work in different directions.

[0004] However, in actual use, the weight of the water supply pipe is mostly borne by the bidirectional rotating screw. After long-term use, the screw is prone to damage due to stress. Furthermore, when adjusting the height of the water supply pipe, the device can only raise or lower both sides of the water supply pipe simultaneously. When the water supply pipe is installed on uneven ground, it is difficult to adjust the height of one side of the water supply pipe separately to adapt to the complex installation environment. Utility Model Content

[0005] This utility model provides a protective support frame for agricultural irrigation water supply pipes. It features two symmetrical height adjustment mechanisms that allow for individual adjustment of the height of the mounting plate and the water supply pipe on one side. Furthermore, a first rotating rod can share the stress on the screw, and the sliding plate ratchet can transfer the stress on the screw to the mounting base. This solves the problems mentioned in the background art.

[0006] In existing support frames, the weight of the water supply pipe is mostly borne by the height-adjusting screw, which is not suitable for long-term use. Furthermore, existing support frames make it difficult to adjust the water supply pipe on one side individually to adapt to complex installation environments.

[0007] To achieve the above objectives, the protective support frame for agricultural irrigation water supply pipes includes a mounting plate and a base plate. Two symmetrically distributed height adjustment mechanisms are provided between the mounting plate and the base plate. Each height adjustment mechanism includes a first rotating rod and a second rotating rod rotatably connected between the mounting plate and the base plate. A mounting seat is fixedly connected to the top surface of the base plate, and a screw is rotatably connected to the top of the mounting seat. A threaded slider is fixedly connected between the two second rotating rods, and the threaded slider and the screw are connected by a through thread.

[0008] In the above technical solution, the two height adjustment mechanisms are used to adjust the height of the two sides of the mounting plate. By rotating the screw, the threaded slider can drive the second rotating rod to rotate, thereby realizing the height adjustment of the mounting plate. At the same time, the first rotating rod can share the stress on the screw and play a protective role for the screw.

[0009] In another technical solution, the mounting base is provided with a support and limiting component inside, and the mounting base is provided with a through mounting groove. The support and limiting component includes a first ratchet tooth fixedly connected to the bottom surface of the mounting groove and two sliding plates. The two sliding plates are respectively fixedly connected to both sides of the two second rotating rods.

[0010] Each of the sliding plates has a movable groove on its opposite side, and a connecting rod is rotatably arranged between the two movable grooves. A ratchet gear is fixedly connected to the outside of the connecting rod, and the ratchet gear meshes with the first ratchet tooth.

[0011] In this technical solution, the support limiting component shares the stress on the screw from the threaded slider through the sliding plate, ratchet, first ratchet and mounting base, and keeps the height of the mounting plate stable after the height adjustment mechanism has adjusted the height of the mounting plate.

[0012] Based on this, in order to prevent the height of both sides of the mounting plate from dropping synchronously due to the weight of the water supply pipe during long-term irrigation, a movable cover is slidably connected inside the movable groove. A positioning groove is opened on one side of the movable cover. Positioning blocks are fixedly connected to both ends of the connecting rod, and the positioning blocks are slidably connected to the positioning groove.

[0013] The inner wall of the movable groove is fixedly connected with a second ratchet tooth distributed in a ring, and the outer side of the movable cover is provided with movable teeth, which mesh with the second ratchet tooth.

[0014] The movable cover has a groove on its outside, the movable tooth is slidably connected to the groove, and a return spring is fixedly connected between the movable tooth and the groove.

[0015] The mechanical self-locking mechanism formed by the engagement of the No. 1 ratchet, No. 2 ratchet, ratchet gear, and movable teeth effectively reduces the impact of water flow vibration and the weight of the water supply pipe on the height of the mounting plate, thus improving the stability of the device.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In this protective support frame for agricultural irrigation water supply pipes, two symmetrical height adjustment mechanisms are set up, which can adjust the height of the mounting plate and the water supply pipe on one side separately. This allows the device to adapt to complex installation environments. In addition, the first rotating rod can share the stress on the screw, and the sliding plate ratchet can also transfer the stress on the screw to the mounting base, further protecting the screw.

[0018] Meanwhile, by setting up a support limiting component, the mechanical self-locking is formed by the cooperation between the No. 1 ratchet, the No. 2 ratchet, the ratchet gear and the movable tooth. Under long-term irrigation operation of the water supply pipe, the height of the mounting plate can be effectively prevented from changing due to water flow vibration or the weight of the water supply pipe, thus improving the stability of the device.

[0029] 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.

[0030] Currently, in existing support frames, the weight of the water supply pipe is mostly borne by the height-adjusting screw, which is unsuitable for long-term use. Furthermore, existing support frames cannot individually adjust the water supply pipe in one direction to adapt to complex installation environments. This utility model provides a protective support frame for agricultural irrigation water supply pipes. See [link to relevant documentation]. Figure 1 and Figure 2 As shown, the device includes a mounting plate 1 and a base plate 2. Two symmetrically distributed height adjustment mechanisms 3 are provided between the mounting plate 1 and the base plate 2. The height adjustment mechanism 3 includes a first rotating rod 31 and a second rotating rod 32 rotatably connected between the mounting plate 1 and the base plate 2. A mounting base 33 is fixedly connected to the top surface of the base plate 2. A screw 34 is rotatably connected to the top of the mounting base 33. A threaded slider 321 is fixedly connected between the two second rotating rods 32. The threaded slider 321 and the screw 34 are connected by a through thread. A support and limiting component 4 is provided inside the mounting base 33.

[0031] Two height adjustment mechanisms 3 are used to adjust the height of the two sides of the mounting plate 1 respectively. The first rotating rod 31 and the second rotating rod 32 share a rotating shaft at the mounting point on the bottom surface of the mounting plate 1, and the deflection directions of the two bottoms are opposite. The first rotating rod 31 can not only ensure the stable rotation of the mounting plate 1, but also share part of the weight of the mounting plate 1 and the water supply pipe. When adjusting the height of the mounting plate 1, the threaded slider 321 can be moved along the axis of the screw 34 by rotating the screw 34. Under the deflection of the second rotating rod 32, the height of the mounting plate 1 on one side can be adjusted. In actual use, the height of the mounting plate 1 can also be adjusted by rotating the two screws 34 simultaneously.

[0032] The support and limiting component 4 is used to share the stress on the screw 34 from the threaded slider 321, and to keep the height of the mounting plate 1 stable after the height adjustment mechanism 3 has adjusted the height of the mounting plate 1.

[0033] During irrigation, the movement of water inside the water supply pipe can easily cause vibration between the pipe and the mounting plate 1. Prolonged irrigation can lead to changes in the position of the threaded slider 321 on the screw 34, resulting in a discrepancy between the water supply pipe's height and the preset height. Therefore, in specific implementation, please refer to... Figure 2 and Figure 3As shown, the mounting base 33 has a through mounting groove 331. The support and limiting component 4 includes a first ratchet 41 fixedly connected to the bottom surface of the mounting groove 331 and two sliding plates 42. The two sliding plates 42 are respectively fixedly connected to both sides of the two second rotating rods 32.

[0034] The sliding plate 42 has movable grooves 421 on both sides. A connecting rod 43 is rotatably arranged between the two movable grooves 421. A ratchet 45 is fixedly connected to the outside of the connecting rod 43. The ratchet 45 meshes with the first ratchet 41.

[0035] When the second rotating rod 32 rotates at the bottom, the sliding plate 42 drives the ratchet 45 to rotate and translate along the first ratchet 41 in the mounting groove 331. When the second rotating rod 32 stops rotating, the ratchet 45 and the first ratchet 41 maintain a meshing relationship and achieve mechanical self-locking. This can effectively prevent the phenomenon of the mounting plate 1 shifting in height under long-term irrigation. Furthermore, the sliding plate 42 can decompose the stress caused by the threaded slider 321 on the screw 34 into vertical force and horizontal force. The vertical force is transmitted to the mounting base 33 by the ratchet 45, and the vertical force is transmitted to the first ratchet 41 by the ratchet 45, and finally to the mounting base 33 as well, further reducing the stress on the screw 34.

[0036] Furthermore, to further prevent the vibration of the water supply pipe from affecting the ratchet 45 and causing it to rotate, see [link to relevant documentation]. Figure 4 As shown, a movable cover 44 is slidably connected inside the movable groove 421. The movable cover 44 can slide within the movable groove 421 along its axial direction. A positioning groove 444 is provided on one side of the movable cover 44. Positioning blocks 431 are fixedly connected to both ends of the connecting rod 43. The positioning blocks 431 are slidably connected to the positioning groove 444. When it is necessary to adjust the height of the mounting plate 1, the operator can push the movable cover 44 outwards to separate the positioning blocks 431 from the positioning groove 444. At this time, the connecting rod 43 and the ratchet 45 can rotate.

[0037] Furthermore, to prevent the height of mounting plate 1 from decreasing synchronously on both sides due to the weight of the water supply pipe during prolonged irrigation, see [reference needed]. Figure 2 and Figure 5 As shown, the inner wall of the movable groove 421 is fixedly connected with a second ratchet 422 arranged in a ring. The direction of the first ratchet 41 and the second ratchet 422 can be set so that the second rotating rod 32 can rotate to push the mounting plate 1 to rise, but cannot rotate in the opposite direction to make the mounting plate 1 fall. This can effectively avoid the above problems.

[0038] In order to facilitate the staff to flexibly adjust the height of the mounting plate 1, the movable cover 44 is provided with movable teeth 443 on the outside. Movable teeth 443 mesh with ratchet teeth 422. The movable cover 44 is provided with grooves 441 on the outside. Movable teeth 443 are slidably connected to grooves 441. A return spring 442 is fixedly connected between movable teeth 443 and grooves 441.

[0039] When the second rotating rod 32 rotates in the direction that raises the mounting plate 1, the movable tooth 443 is squeezed by the tooth surface of the second ratchet 422 and retracts into the groove 441, thereby realizing the synchronous rotation of the movable cover 44, the connecting rod 43 and the ratchet 45. When the second rotating rod 32 rotates in the direction that lowers the mounting plate 1, the movable cover 44, the connecting rod 43 and the ratchet 422 are limited, so that the movable cover 44, the connecting rod 43 and the ratchet 45 can no longer rotate. When the operator needs to adjust the height of the mounting plate 1, he only needs to pull the movable cover 44 out of the sliding plate 42 to continue the adjustment operation.

[0040] The working principle of this device is as follows:

[0041] When it is necessary to adjust the height of one side of the mounting plate 1, the operator can rotate the screw 34 on the corresponding side, so that the threaded slider 321 moves along the axis of the screw 34. At this time, the bottom of the second rotating rod 32 moves with the threaded slider 321, and the whole rotates, causing the height of the corresponding side of the mounting plate 1 to change. When it is necessary to adjust the overall height of the mounting plate 1, the operator can rotate the screws 34 on both sides simultaneously, or rotate the screws 34 on both sides one after the other, so that the height of the two sides of the mounting plate 1 gradually aligns.

[0042] Before adjustment, the movable cover 44 at the corresponding position can be pulled outward to separate the positioning block 431 from the positioning groove 444, so that the connecting rod 43 and the ratchet 45 can move and rotate along the mounting groove 331. After adjustment, the movable cover 44 can be reset. During long-term use of the device, the vibration of the water flow in the water supply pipe and the weight of the water supply pipe itself may cause the overall height of the mounting plate 1 to drop. At this time, the movable tooth 443, the ratchet 45, the first ratchet 41 and the second ratchet 422 will form a mechanical self-lock, which effectively avoids the phenomenon of the height of the mounting plate 1 shifting under long-term irrigation and improves the stability of the device.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
