Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and in particular to an irrigation device for agricultural planting greenhouses. Background Technology

[0002] In modern agricultural production, greenhouse cultivation plays a vital role, providing a relatively stable growing environment for crops, effectively extending the crop growth cycle, and increasing yield. However, the irrigation system that supports it has long faced numerous problems that need to be solved.

[0003] Fixed sprinkler irrigation devices involve installing fixed sprinklers on the top of the greenhouse or at specific locations, with water sprayed from the sprinklers at a fixed angle and within a fixed range.

[0004] However, while the current fixed sprinkler irrigation system reduces the intensity of manual labor to some extent, and irrigation can be carried out simply by opening the water supply valve after the sprinkler is fixed on the top of the greenhouse or in a specific position, it cannot adapt to the changes in height and shape of crops at different growth stages because the position of the sprinkler is fixed.

[0005] For example, during the seedling stage of crops, the sprinkler head may be too high, resulting in an excessive spray area and some water being wasted in non-planted areas. Later in the growth stage of crops, as the plants grow taller, the fixed sprinkler head may not be able to deliver water to the area below the crops, leading to insufficient irrigation.

[0006] At the same time, this device is also difficult to use for greenhouses with irregular planting layouts to achieve precise irrigation, which can easily lead to irrigation dead zones and affect crop yields.

[0007] Therefore, how to provide an irrigation device for agricultural greenhouses is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0008] One objective of this invention is to provide an irrigation device for agricultural greenhouses. This invention can precisely adjust the height of the irrigation pipe through components such as servo motors and lead screws to adapt to crops of different heights. It can also flexibly switch the angle of the irrigation pipe and select vertical or horizontal spraying according to the crop shape to improve water use efficiency.

[0009] An agricultural greenhouse irrigation device according to an embodiment of the present utility model includes an irrigation vehicle, a truss, and an irrigation pipe;

[0010] The irrigation vehicle is fixedly mounted on both sides with brackets. T-shaped grooves are formed in the brackets, and T-shaped sliders are slidably mounted in the T-shaped grooves. The outer side of the T-shaped sliders is connected to the irrigation pipe via hinges. Several sets of nozzles are installed on the outer wall of the irrigation pipe. A lead screw is vertically and rotatably mounted in the T-shaped grooves. A servo motor is fixedly mounted on the top of the brackets. The output shaft of the servo motor is connected to the lead screw for transmission. A screw hole is vertically opened through the inside of the T-shaped slider. The lead screw passes through the screw hole and is threaded into the screw hole.

[0011] Furthermore, a rotating shaft is installed on the upper part of the outer wall on both sides of the irrigation pipe, and a limit block is movably installed on the rotating shaft. Limit buckles are correspondingly installed on the rear wall of the two sets of limit blocks.

[0012] Furthermore, a connector is installed on the rear side of the top of the irrigation vehicle, and flexible hoses are fixedly installed on the top of the two sets of irrigation pipes. The other end of each set of flexible hoses is connected to the connector.

[0013] Furthermore, the irrigation vehicle is equipped with drive wheels around its perimeter, allowing it to move while mounted on the truss.

[0014] Furthermore, the two sets of limiting blocks are fixedly connected by limiting buckles, and the two sets of limiting blocks are fitted onto the bracket.

[0015] Furthermore, the drive wheel is a solid rubber wheel, and the outer surface of the drive wheel is provided with anti-slip patterns.

[0016] Furthermore, an induction guide rail is laid on the truss along the travel route of the irrigation vehicle, and an induction probe is installed at the bottom of the irrigation vehicle to monitor the relative position of the irrigation vehicle and the induction guide rail in real time.

[0017] Furthermore, the truss is made of aluminum alloy, and the surface of the truss is anodized to form a dense oxide film.

[0018] The beneficial effects of this utility model are:

[0019] 1. This utility model, through the ingenious combination of a servo motor, lead screw, T-shaped slider, and screw hole, can precisely control the vertical height of the irrigation pipe. This means that whether it is a tall vine-like crop or a leafy vegetable growing close to the ground, the nozzle can be ensured to be at the optimal spraying height, so that the water flow evenly covers each crop, greatly improving the accuracy of irrigation, reducing the problem of uneven irrigation caused by unsuitable height, and ensuring a uniform supply of water needed for crop growth.

[0020] 2. This utility model utilizes an angle adjustment structure composed of a rotating shaft, a limiting block, and a limiting buckle. Operators can easily switch the irrigation pipe between vertical and horizontal positions. For crops with different growth habits and plant shapes, such as tall corn and sorghum, vertical spraying is used to irrigate deep into the roots, while short strawberries and lettuce are sprayed horizontally to fully cover the leaves. This precisely adapts to the irrigation needs of various crops, further improving water use efficiency and avoiding water waste in non-target areas. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0028] refer to Figure 1-4 An agricultural greenhouse irrigation device includes an irrigation vehicle 1, a truss 2, and an irrigation pipe 6;

[0029] The irrigation truck 1 has brackets 3 fixedly installed on both sides. T-shaped grooves 8 are opened in the brackets 3. T-shaped sliders 10 are slidably installed in the T-shaped grooves 8. The outside of the T-shaped sliders 10 is connected to the irrigation pipe 6 through hinges 13. Several sets of nozzles 7 are installed on the outer wall of the irrigation pipe 6. A lead screw 17 is vertically and rotatably installed in the T-shaped grooves 8. A servo motor 11 is fixedly installed on the top of the brackets 3. The output shaft of the servo motor 11 is connected to the lead screw 17 for transmission. A screw hole 12 is vertically opened through the inside of the T-shaped slider 10. The lead screw 17 passes through the screw hole 12 and is threadedly engaged with the screw hole 12.

[0030] Among them, a rotating shaft 14 is installed on the upper part of the outer wall on both sides of the irrigation pipe 6, and a limit block 15 is movably installed on the rotating shaft 14. A limit buckle 16 is installed on the rear wall of the two sets of limit blocks 15 respectively.

[0031] Specifically, the two sets of limiting blocks 15 are fixedly connected by limiting buckles 16, and the two sets of limiting blocks 15 are fitted on the bracket 3. When it is necessary to adjust the angle of the irrigation pipe 6, the limiting buckles 16 can be opened first, and the limiting blocks 15 can be rotated around the pivot 14 to release the restraint on the irrigation pipe 6. Then, the irrigation pipe 6 can be rotated to a horizontal state by the hinge 13.

[0032] Secondly, a connector 4 is installed on the rear side of the top of the irrigation truck 1, and hoses 5 are fixedly installed on the top of the two sets of irrigation pipes 6. The other end of the two sets of hoses 5 are connected to the connector 4. The water source is connected to the connector 4 on the top of the irrigation truck 1 through an external pipe. The water is diverted through the connector 4 to the two hoses 5, and then transported to the irrigation pipes 6, and finally sprayed out from the nozzle 7 to achieve large-area irrigation.

[0033] In this embodiment, irrigation can be completed by spraying the crops with each set of nozzles 7, and the irrigation pipe 6 can be easily switched between vertical and horizontal postures. Therefore, the irrigation method can be freely adjusted according to the type of crop. For example, vertical spraying can be used when irrigating tall crops, while horizontal spraying can be used when irrigating low-lying crops. In addition, the servo motor 11 can also drive the T-shaped slider 10 and the irrigation pipe 6 to move up and down, thereby adjusting the height and improving flexibility.

[0034] refer to Figure 1-4 The irrigation truck 1 is equipped with drive wheels 9 around its perimeter, and the irrigation truck 1 can move on top of the truss 2 via the drive wheels 9;

[0035] Specifically, an induction guide rail is laid on the truss 2 along the travel route of the irrigation vehicle 1, and an induction probe is installed at the bottom of the irrigation vehicle 1. The induction probe monitors the relative position of the irrigation vehicle 1 and the induction guide rail in real time. Before the irrigation operation begins, the induction guide rail is pre-set on the truss 2. It can be installed by means of pasting or fixing with slots to ensure accurate positioning. After the irrigation vehicle 1 starts, the induction probe at the bottom senses the distance and position deviation from the induction guide rail in real time. Once there is a deviation from the preset track, the control system will automatically adjust the speed and direction of the drive wheel 9 to bring the irrigation vehicle 1 back to the correct track, ensuring uniform and comprehensive irrigation coverage.

[0036] Among them, truss 2 is made of aluminum alloy, and the surface of truss 2 is anodized to form a dense oxide film. Aluminum alloy has the advantages of being lightweight and high-strength, which makes it easy to build and install in the greenhouse, reducing the overall structural load. The oxide film after anodizing can effectively resist the erosion of humidity, high temperature and possible corrosive gases or liquids in the greenhouse, greatly extending the service life of truss 2.

[0037] Secondly, the drive wheel 9 is a solid rubber wheel, and the outer surface of the drive wheel 9 is provided with anti-slip patterns. The solid rubber wheel has good elasticity and can play a buffering role during travel, reducing the damage of vibration to various parts of the irrigation device. At the same time, the anti-slip patterns can enhance the friction between the drive wheel 9 and the surface of the truss 2, ensuring that the irrigation vehicle 1 can travel stably and reliably without slipping even when there are water stains or dust on the surface of the truss 2.

[0038] In this embodiment, the drive wheel 9 is driven by a motor, which is connected to the control system. The rotation of the drive wheel 9 can be precisely controlled according to the preset irrigation route and speed requirements, so as to realize the automated and intelligent movement of the irrigation vehicle 1.

[0039] Working principle: When irrigation is started, the water source is first connected to the connector 4 on the top of the irrigation truck 1. The water flow is split along the connector 4 to two hoses 5. The hoses 5 stably deliver the water to the inside of the irrigation pipe 6, providing the necessary conditions for subsequent water spraying. For the height adjustment of the irrigation pipe 6, the servo motor 11 on the top of the bracket 3 is started, and its output shaft drives the lead screw 17 to rotate. Since the lead screw 17 and the screw hole 12 inside the T-shaped slider 10 adopt a threaded engagement structure, during the rotation of the lead screw 17, the T-shaped slider 10 will move vertically along the axis of the lead screw 17 within the T-shaped groove 8. The outside of the T-shaped slider 10 is rigidly connected to the irrigation pipe 6 through the hinge 13, so the irrigation pipe 6 will move accordingly. The irrigation pipe 6 can be moved up and down to precisely adjust to the appropriate irrigation height for crops of different heights, meeting diverse irrigation needs. Whether the plants are tall or short, it ensures effective water coverage. Regarding the angle adjustment of the irrigation pipe 6, when it is necessary to change the spray angle, such as switching from vertical to horizontal spraying to accommodate different types of crops, the operator can first open the limiting buckle 16 on the rear wall of the limiting block 15. Then, rotating the limiting block 15 around the rotating shaft 14 releases its constraint on the irrigation pipe 6. Next, gently rotate the irrigation pipe 6 using the hinge 13 until the desired horizontal position is achieved, ensuring that the spray direction is accurately directed towards the target crop area. Precision irrigation is now achieved. The movement of the irrigation truck 1 is driven by motors on its four drive wheels 9, which are connected to an intelligent control system. Before the irrigation operation begins, workers pre-install induction guide rails on the truss 2 along the predetermined route of the irrigation truck 1. Reliable methods such as adhesive or clip fixing can be used to ensure the precise positioning of the induction guide rails. After the irrigation truck 1 starts, the sensor probes installed at its bottom continuously monitor the distance and positional deviation between itself and the induction guide rails. Once the control system determines, based on the data from the sensor probes, that the irrigation truck 1 has deviated from the preset track, even by a slight deviation, the control system will quickly and automatically adjust the drive wheels according to a preset algorithm. The control system adjusts the rotation speed and direction of the left drive wheel 9. For example, if the irrigation truck 1 deviates to the left, the control system will appropriately reduce the rotation speed of the left drive wheel 9 while increasing the rotation speed of the right drive wheel 9, causing the irrigation truck 1 to return to the right and always stay on the correct travel track. In this way, the irrigation truck 1 can move steadily along the truss 2 along the predetermined route, and spray water evenly in a fan shape or other preset ideal shape through the nozzles 7 as it moves. This achieves comprehensive, thorough, and efficient irrigation of crops in the greenhouse. While greatly improving irrigation efficiency, the precise control method effectively avoids the unnecessary waste of water resources, providing a reliable and intelligent solution for irrigation of agricultural greenhouses.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
