Description

Technical Field

[0001] This utility model relates to the field of agricultural and forestry sprinkler irrigation technology, and in particular to a pipeline anti-pressure mechanism for agricultural and forestry sprinkler irrigation. Background Technology

[0002] In the process of agricultural and forestry sprinkler irrigation, an issue that cannot be ignored is how to safely cross the pipelines through roads. Roads are the only way for pedestrians and motor vehicles to pass through. When the pipelines cross the roads, the damage caused by motor vehicles must be taken into account. Once the pipelines are damaged, it will not only lead to the interruption of sprinkler irrigation and affect the normal growth of plants, but also increase additional maintenance costs and time costs.

[0003] A search of Chinese Patent Publication No. CN222687670U reveals a pressure-resistant device for garden sprinkler irrigation pipes, relating to the technical field of pressure-resistant devices. The device includes a base plate and a baffle. Limiting components are fixedly connected to the opposing surfaces of a first and second support assembly on the same side. A connecting shaft is rotatably connected to the middle of the two first and two second support assemblies. An inclined plate is symmetrically rotatably connected to the baffle. A driving assembly is provided at the lower part of the baffle, used to drive the movement of the first and second support assemblies. This invention allows the first and second support assemblies to move by operating the driving assembly, enabling the device to adjust the height of the baffle according to the size of the water pipe. The rotatable connection between the baffle and the inclined plate allows for adjustment of the inclined plate's placement angle according to different height positions, ensuring the lower end of the inclined plate remains in contact with the ground. The inclined plate provides support to the baffle, enhancing its pressure resistance.

[0004] However, in implementing the relevant technology, the following problems were found in the above-mentioned anti-pressure device for sprinkler irrigation pipelines: In the prior art, when the baffle is adjusted to a suitable height and is run over by a motor vehicle, the bidirectional threaded rod, main rod one and main rod two are under stress. Long-term use can easily lead to deformation and damage to the bidirectional threaded rod, main rod one and main rod two. Based on this, this utility model designs an anti-pressure mechanism for agricultural and forestry sprinkler irrigation pipelines to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a pressure-resistant mechanism for pipelines used in agricultural and forestry sprinkler irrigation, so as to solve the problem mentioned in the background art that long-term use can easily lead to deformation and damage of the bidirectional threaded rod, main rod one and main rod two.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pipeline anti-pressure mechanism for agricultural and forestry sprinkler irrigation, including a base, a bearing plate provided on the top of the base, and inclined plates rotatably connected to both sides of the bearing plate;

[0007] The top of the base and the bottom of the support plate are slidably connected to a connecting frame, and the top of the base is provided with a connecting rod one and a connecting rod two, which are hinged to each other. The two ends of the connecting rod one and the connecting rod two are respectively hinged to the connecting frame.

[0008] Each base has a support component on its top, which is used to support the load-bearing plate.

[0009] As a preferred embodiment, the support component includes a fixed cylinder, a threaded block, and a screw rod. The fixed cylinder is located at the top of the base, the threaded block is rotatably connected to the top of the fixed cylinder, and the screw rod is threadedly connected to the threaded block.

[0010] As a preferred embodiment, the support component includes a limiting cylinder, a telescopic rod, and slots. The limiting cylinder is located at the top of the base, and the telescopic rod is slidably connected to the limiting cylinder. The slots are respectively opened through the outer walls of the limiting cylinder and the telescopic rod.

[0011] As a preferred embodiment, a screw rod is threadedly installed at the top end of the telescopic rod.

[0012] As a preferred embodiment, a bidirectional lead screw is rotatably connected to the bottom of the bearing plate, and a worm gear is fixedly installed on the outer side wall of the bidirectional lead screw.

[0013] As a preferred embodiment, a worm gear is rotatably connected to the bottom of the bearing plate, and the worm gear is meshed with the worm wheel.

[0014] As a preferred embodiment, a limiting plate one and a limiting plate two are fixedly installed on the top of the base.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. By setting up support components, a bearing plate, and an inclined plate, after the bearing plate is adjusted to a suitable height, the inclined plate is rotated upward to adjust the height of the support components. The support components are rotated upward to contact the bottom of the bearing plate, and the inclined plate is rotated downward to contact the ground. When a motor vehicle runs over the inclined plate and the bearing plate, the stability of the bearing plate is increased by the support components, thereby effectively solving the problem of deformation and damage of the bidirectional threaded rod, main rod one, and main rod two under rolling pressure in the existing technology.

[0017] 2. Through the worm, worm wheel and double screw, the worm is rotated to drive the worm wheel to rotate, and the worm wheel drives the double screw to rotate, so that the connecting frame at the bottom of the bearing plate moves closer to each other. The connecting frame drives the movement of connecting rod one and connecting rod two, adjusting the height of the bearing plate, so that the inclined surface at the bottom of one side of the inclined plate fully contacts and adapts to the road surface.

Detailed Implementation

[0023] 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.

[0024] This utility model provides, for example Figure 1-4The illustrated anti-pressure mechanism for agricultural and forestry sprinkler irrigation pipes includes a base 1, a bearing plate 2 on the top of the base 1, and inclined plates 3 rotatably connected to both sides of the bearing plate 2. When a motor vehicle runs over the inclined plates 3 and the bearing plate 2, the vehicle will not directly run over the pipe, thus protecting the pipe and ensuring smooth sprinkler irrigation. Connecting frames 5 are slidably connected to the top of the base 1 and the bottom of the bearing plate 2, respectively. Connecting rod 6 and connecting rod 7 are respectively provided on the top of the base 1, and are hinged together. The two ends of connecting rod 6 and connecting rod 7 are respectively hinged to the connecting frames 5. Support components 4 are provided on the top of the base 1. After the bearing plate 2 is adjusted to a suitable height, it rotates... The support component 4 moves upward to contact the bottom of the bearing plate 2, providing stable support for the bearing plate 2. The support component 4 is used to support the bearing plate 2. A double-acting screw 8 is rotatably connected to the bottom of the bearing plate 2. A worm wheel 9 is fixedly installed on the outer wall of the double-acting screw 8. A worm 10 is rotatably connected to the bottom of the bearing plate 2. The worm 10 and the worm wheel 9 are meshed together. Rotating the worm 10 drives the worm wheel 9 to rotate. The worm wheel 9 drives the double-acting screw 8 to rotate. The double-acting screw 8 drives the connecting frame 5 at the bottom of the bearing plate 2 to move closer to each other. The connecting frame 5 drives the connecting rod 6 and the connecting rod 7 to move, realizing the height adjustment of the bearing plate 2, so that the inclined surface of one side of the bottom of the inclined plate 3 fully contacts and adapts to the road surface.

[0025] In this embodiment, as Figure 1 As shown, the support component 4 includes a fixed cylinder 41, a threaded block 42, and a screw 43. The fixed cylinder 41 is located on the top of the base 1. The threaded block 42 is rotatably connected to the top of the fixed cylinder 41. The screw 43 is threadedly connected to the threaded block 42. After the height of the bearing plate 2 is adjusted, the threaded block 42 is rotated to drive the screw 43 to move upward and contact the bottom of the bearing plate 2, thus providing stable support for the bearing plate 2.

[0026] In this embodiment, as Figure 4 As shown, the support component 4 includes a limiting cylinder 401, a telescopic rod 402, and a slot 403. The limiting cylinder 401 is located on the top of the base 1. The telescopic rod 402 is slidably connected to the limiting cylinder 401. The slot 403 is respectively opened through the outer side wall of the limiting cylinder 401 and the telescopic rod 402. The top of the telescopic rod 402 is threaded with a screw 404. The telescopic rod 402 is moved upward to a suitable position, and the limiting cylinder 401 and the slot 403 on the telescopic rod 402 are connected with bolts and nuts to limit the height of the telescopic rod 402. When the top of the telescopic rod 402 does not contact the bottom of the bearing plate 2 after the height of the telescopic rod 402 is adjusted, the screw 404 is rotated to contact the bottom of the bearing plate 2.

[0027] In this embodiment, as Figure 2As shown, a first limiting plate 11 and a second limiting plate 12 are fixedly installed on the top of the base 1. The pipe passes between the first limiting plate 11 and the second limiting plate 12. The pipe is limited by the first limiting plate 11 and the second limiting plate 12, and the pipe is prevented from being crushed and damaged by the inclined plate 3 and the bearing plate 2.

[0028] Working principle of this utility model: This utility model is a pipeline anti-pressure mechanism for agricultural and forestry sprinkler irrigation. First, when in use, the base 1 is placed in the use position, and the worm gear 10 is rotated to drive the worm wheel 9 to rotate. The worm wheel 9 drives the double-acting screw 8 to rotate. The double-acting screw 8 drives the connecting frame 5 at the bottom of the bearing plate 2 to move closer to each other. The connecting frame 5 drives the connecting rod 1 6 and the connecting rod 2 7 to move, thereby realizing the height adjustment of the bearing plate 2, so that the inclined surface at the bottom of one side of the inclined plate 3 fully contacts and adapts to the road surface.

[0029] Then, the inclined plate 3 is rotated upward to adjust the height of the support component 4. The screw block 42 is rotated to drive the screw 43 to move upward and contact the bottom of the bearing plate 2, providing stable support for the bearing plate 2. The pipe is passed between the limiting plate 11 and the limiting plate 12. Finally, the inclined plate 3 is rotated downward to contact the ground. When a motor vehicle runs over the inclined plate 3 and the bearing plate 2, the stability of the bearing plate 2 is increased by the support component 4.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
