Description

Technical Field

[0001] This utility model belongs to the field of agricultural irrigation technology, specifically relating to an automatic irrigation system for water-saving and drought-resistant wheat fields. Background Technology

[0002] Traditional self-propelled irrigation equipment often suffers from design flaws in its height adjustment mechanism. Most equipment uses a single-sided independent adjustment method, which lacks a precise guiding and limiting structure during the adjustment process. This makes it difficult for the height of the two walking wheels to be synchronized. When the height difference between the two sides of the field exceeds a certain limit, the equipment will tilt significantly. This tilt not only increases the stress load at the pipe connection points but also causes uneven irrigation width, resulting in insufficient irrigation in the edge areas of wheat fields. Furthermore, when the equipment moves in the field or encounters terrain changes such as field ridges or soil protrusions, the vibration of the machine body can easily cause stress concentration at the pipe connection points, leading to loosening or seal failure and causing irrigation water leakage. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide an automatic irrigation system for wheat fields that saves water and resists drought, thereby solving the aforementioned issues.

[0004] To achieve the above objectives, a water-saving and drought-resistant automatic irrigation system for wheat fields includes a self-propelled base and a main diversion pipe. One end of the main diversion pipe has a connector, and a connecting pipe is located in front of the connector. The connector and the connecting pipe are connected by a corrugated telescopic pipe. A positioning frame is installed above the self-propelled base, and a limit plate is installed in front of the positioning frame. A guide rail that is slidably connected to the limit plate is installed on the outer wall of the corrugated telescopic pipe. Two adjusting frames are installed on the self-propelled base, and adjusting rods are threadedly connected to the self-propelled base and the adjusting frames. A support plate is rotatably connected to the bottom of the adjusting rod, and an installation rod is located below the support plate. The support plate and the installation rod are connected by a spring, and two self-propelled wheels are installed on one side of the installation rod.

[0017] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0018] Example 1:

[0019] like Figure 1As shown in Figure 4, this utility model provides the following technical solution: it includes a self-propelled base 1 and a main guide pipe 2. One end of the main guide pipe 2 is provided with a connector 21, and a connecting pipe 22 is provided on the front side of the connector 21. The connector 21 and the connecting pipe 22 are connected by a corrugated telescopic pipe 23. A positioning frame 25 is installed on the top of the self-propelled base 1. A limit plate 27 is installed on the front side of the positioning frame 25. A guide rail 24 that is slidably connected to the limit plate 27 is installed on the outer wall of the corrugated telescopic pipe 23. Two adjusting frames 3 are installed on the self-propelled base 1. An adjusting rod 31 is threadedly connected to the self-propelled base 1 and the adjusting frame 3. A support plate 32 is rotatably connected to the bottom of the adjusting rod 31. An installation rod 33 is provided below the support plate 32. The support plate 32 and the installation rod 33 are connected by a spring 34. Two self-propelled wheels 36 are installed on one side of the installation rod 33.

[0020] In this implementation scheme: the self-propelled base 1 serves as the carrier of the load-bearing device, moving along both sides of the wheat field. Two self-propelled bases 1 support the truss irrigation pipe, causing the truss to shift above the wheat, irrigating it by spraying water. A connector 21 is welded and fixed to one end of the main diversion pipe 2. A connecting pipe 22 is fitted to the front of the connector 21, and a corrugated expansion joint 23 achieves a sealed connection between the connector 21 and the connecting pipe 22. The corrugated expansion joint 23, with its corrugated outer wall design and the use of an elastic material, allows it to contract. It is fixed to the top of the self-propelled base 1 by bolts. A positioning frame 25 is installed, with a limit plate 27 welded to the front side of the positioning frame 25. A guide rail 24 is welded to the outer wall of the corrugated expansion pipe 23, forming a sliding fit with the limit plate 27. This sliding connection between the guide rail 24 and the limit plate 27 allows the connecting pipe 22 to connect with the truss irrigation pipe used for irrigation. When the two self-propelled bases 1 move along both sides of the wheat planting area, causing the truss to move laterally across the wheat for irrigation, the height of the two self-propelled bases 1 cannot be kept consistent due to their movement along the sides of the land. At this time, the corrugated expansion pipe 22 can be used to connect the connecting pipe 22 and the connector 21. The flexible connection of the telescopic pipe 23, together with the guide rail 24, slides on the limiting plate 27, allowing the guide rail 24 to retract and the connecting pipe 22 to move up and down. The guide rail 24 slides on the inner wall of the limiting plate 27, enabling the truss to move stably between the two main diversion pipes 2, while preventing the truss from being affected by the up-and-down bumping of the two self-propelled bases 1, which would affect the sealing connection between the truss irrigation pipe and the main diversion pipe 2. Two adjusting frames 3 are symmetrically installed on both sides of the self-propelled base 1, which can be adjusted by rotating the adjusting rod 31. The bottom of the adjusting rod 31 is connected to the support plate 32 through a rotating connection structure such as a bearing. The lower part of the support plate 32... The base is equipped with an installation rod 33, and the support plate 32 is connected to the installation rod 33 by a connecting plate 35. The self-propelled wheel 36 rotates on one side of the installation rod 33, so that the self-propelled wheel 36 supports the self-propelled base 1 and allows it to walk on the ground. At this time, the height of the support plate 32 can be adjusted by adjusting the adjustment rod 31, and the height of the installation rod 33 can be adjusted. When the height difference between the springs 34 on the left and right sides of the self-propelled base 1 is large, the self-propelled wheels 36 on the left and right sides can be adjusted to make the self-propelled base 1 maintain stable self-movement. This allows the self-propelled base 1 on both sides of the land to move smoothly, increasing the connection and sealing stability of the truss irrigation pipe.

[0021] A support frame 11 is installed on the self-propelled base 1, and the support frame 11 is fixedly connected to the main irrigation pipe 2. The main irrigation pipe 2 is stably fixed above the self-propelled base 1 by the support frame 11, so as to prevent the main irrigation pipe 2 from shaking or shifting when the self-propelled base 1 encounters field ridges or soil protrusions during its self-propelled journey in the wheat field. This ensures that the sealed connection between the main irrigation pipe and the subsequent truss irrigation pipe is not damaged, and at the same time improves the structural stability of the overall device.

[0022] A limiting rod 311 is installed at the top of the support plate 32. The limiting rod 311 passes through the self-propelled base 1 and the adjustment frame 3. Through the guiding and limiting of the limiting rod 311, it is ensured that the support plate 32 can only be adjusted in the vertical direction, so as to avoid the installation rod 33 from tilting during the adjustment process. This ensures the stable support of the self-propelled wheel 36 on the self-propelled base 1, so that the self-propelled base 1 can still move smoothly when there is a large height difference on both sides of the field.

[0023] The two positioning frames 25 are connected by a fixing plate 26, and the positioning frame 25 is connected to the support frame 11 by a fixing rod 251. The fixing plate 26 enables the two positioning frames 25 to be subjected to force synchronously, preventing the deformation of a single positioning frame 25 due to the sliding load of the limiting plate 27. The fixing rod 251 fixes the positioning frame 25 to the support frame 11, further enhancing the installation stability of the positioning frame 25 and ensuring that the limiting plate 27 does not shake when the guide rail 24 slides on the limiting plate 27, thus accommodating the stable lateral movement of the truss irrigation pipe.

[0024] A limiting groove 271 is provided on the limiting plate 27, and the limiting groove 271 is slidably connected to the guide rail 24. The sliding connection between the limiting groove 271 and the guide rail 24 ensures that the connecting pipe 22 can move up and down with the bumps of the self-propelled base 1, avoiding leakage at the sealed connection between the truss irrigation pipe and the main diversion pipe 2 due to pulling, and ensuring the effective delivery of irrigation water and water-saving effect.

[0025] The mounting rod 33 has connecting plates 35 installed at both ends, and the support plate 32 has a sliding rod 351 installed at the bottom. The sliding rod 351 is slidably connected to the connecting plate 35. When the height of the support plate 32 is adjusted by adjusting the rod 31, the sliding rod 351 can slide up and down along the inner wall of the connecting plate 35, so that the mounting rod 33 always remains horizontal, preventing the mounting rod 33 from tilting. This ensures that the self-propelled wheels 36 on both sides of the mounting rod 33 contact the ground synchronously, improves the stability of the self-propelled base 1 in uneven fields, reduces the probability of device failure, and meets the design purpose of easy promotion.

[0026] The working principle of this technical solution is as follows: Two self-propelled bases 1 are placed on the two sides of the wheat field, ensuring the self-propelled wheels 36 are in stable contact with the ground. The two ends of the truss irrigation pipe are connected to the connecting pipes 22 on both sides. The sealing of the connection between the main diversion pipe 2 and the water source is checked. Based on the flatness of the ground on both sides of the wheat field, the adjusting rod 31 is rotated. Through the sliding cooperation of the support plate 32, connecting plate 35, and sliding rod 351, the height of the self-propelled wheels 36 is adjusted, allowing the self-propelled base 1 to move more horizontally. At this time, the limiting rod 311 slides along the through hole, ensuring that the support plate 32 only moves vertically. The water supply is then turned on. The water source allows water to flow through the main diversion pipe 2, connector 21, and corrugated expansion pipe 23 into the connecting pipe 22 and truss irrigation pipe. After confirming that there is no leakage at each connection, the drive system of the self-propelled base 1 is started, causing it to move at a constant speed along the edge of the wheat field. During the movement of the device, if the height difference between the two self-propelled bases 1 due to ground undulations occurs, the corrugated expansion pipe 23 will slide along the limiting groove 271 of the limiting plate 27 with the guide rail 24, realizing the adaptive adjustment of the connecting pipe 22 up and down. This avoids pulling at the connection between the truss irrigation pipe and the equipment, which could easily cause water leakage, ensuring stable irrigation by the truss irrigation pipe and uniform spraying of the wheat field.
