Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable cultivation technology, and in particular to an automatic irrigation device for fruit and vegetable cultivation. Background Technology

[0002] Fruits and melons need a lot of water to maintain their physiological activities. When rainfall is uneven, irrigation can ensure the water supply for fruits and melons. In arid areas with little rain, the growth of fruits and melons will be affected without irrigation, and may even lead to the death of seedlings. In areas with variable rainfall, irrigation can supplement water as needed. Irrigation can regulate soil moisture and temperature, which is conducive to root growth and nutrient absorption. Appropriate irrigation helps to keep the soil moist and create a good environment for the roots. Reasonable irrigation will result in plump, juicy, sweet, and delicious fruits.

[0003] Agricultural irrigation is crucial for fruit and vegetable cultivation, but traditional irrigation methods have many drawbacks. These methods often consume a lot of water and have low water utilization efficiency. For example, with flood irrigation, a large amount of water resources are wasted during transportation and infiltration. Furthermore, it is impossible to accurately control the amount and area of ​​irrigation, which can easily lead to soil salinization and may also spread crop diseases and pests, affecting the yield and quality of fruits and vegetables. In addition, traditional irrigation relies on manual operation, which is labor-intensive, has a complex irrigation process, and is inefficient, making it difficult to meet the needs of modern large-scale fruit and vegetable cultivation.

[0004] In some existing technologies, traditional irrigation methods often require manual checks of soil moisture to determine whether to irrigate. This involves a high degree of manual intervention and is labor-intensive. There is a lack of devices that can automatically irrigate according to the required amount of water. Furthermore, the irrigation height requirements of fruits and vegetables vary at different growth stages, and the plant height also varies among different varieties. There is a lack of structures that can easily adjust the irrigation height. Utility Model Content

[0005] The main objective of this invention is to provide an automatic irrigation device for fruit and vegetable cultivation. This device can effectively solve the problems mentioned above in the existing technologies, where traditional irrigation methods often require manual checks of soil moisture to determine whether to irrigate, resulting in high manual involvement and labor intensity. Furthermore, there is a lack of devices that can automatically irrigate according to the required water volume. Additionally, the irrigation height requirements of fruits and vegetables vary at different growth stages, and the plant heights of different varieties of fruits and vegetables also differ, resulting in a lack of structures that facilitate the adjustment of irrigation height.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An automatic irrigation device for fruit and vegetable cultivation includes a water supply pipe, an irrigation mechanism installed on the rear side of the outer surface of the water supply pipe, installation mechanisms symmetrically installed on the left and right sides of the outer surface of the water supply pipe, a humidity monitoring mechanism installed at the bottom of each of the installation mechanisms, a water pump box installed at the bottom of the water supply pipe, and a height adjustment mechanism installed on the outer surface of the water pump box.

[0008] Preferably, a drive box is installed on the top of the height adjustment mechanism, and a connecting water pipe is installed at the front end of the water pump box.

[0009] Preferably, the irrigation mechanism includes several water pipes 2, a curved water pipe 3 is installed at the left end of the water conveying pipe 1, and nozzles are fixedly connected to the rear ends of the curved water pipe 3 and the several water pipes 2. Sealing mounting seats are installed at the ends of the curved water pipe 3 and the several water pipes 2 near the water conveying pipe 1, and the several sealing mounting seats are fixedly connected to the water conveying pipe 1.

[0010] Preferably, each of the aforementioned installation mechanisms includes two clamps, which are arranged symmetrically at the top and bottom. The lower clamp has symmetrically arranged slots at the front and back. The inner surfaces of the two slots are symmetrically connected with spring pieces. The opposite sides of the two spring pieces are slidably connected with limit tooth plates. The opposite sides of the two limit tooth plates are symmetrically arranged with limit telescopic plates. The other side of the limit telescopic plates is installed on the inner wall of the slot.

[0011] Preferably, the two limiting toothed plates located on the same side of the same end are provided with a retaining seat on their opposite sides, and the tops of the two retaining seats are respectively fixedly connected to the front and rear sides of the bottom of the upper clamp on the same side of the same end.

[0012] Preferably, a top plate is symmetrically fixedly connected to the top of each of the slots, and a connecting plate is fixedly connected to the bottom of each of the clamps at the lower end. A control component is fixedly connected to the rear end of the connecting plate, and an electric telescopic rod is installed on the inner side of the control component.

[0013] Preferably, each of the humidity monitoring mechanisms includes a support frame, an electronic soil moisture monitor is installed on the inner side of the support frame, and locking blocks are symmetrically engaged on the lower side of the inner surface of the support frame.

[0014] Preferably, the height adjustment mechanism includes an outer frame, a movable seat slidably connected to the inner surface of the outer frame, a threaded rod threadedly connected to the inner surface of the movable seat, protective ramps symmetrically fixed to the lower side of the outer surface of the outer frame, mounting brackets symmetrically fixed to the front and rear of the outer surface of the movable seat, the mounting brackets being installed on the outer surface of the water pump box, the drive box being installed on the top of the outer frame, and the top of the threaded rod being rotatably connected to the output end of the drive box.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This device, through its designed humidity monitoring mechanism, uses an electronic soil moisture monitor to automatically monitor the soil moisture content in real time. When the soil moisture content is less than a preset value, the sensor at the electronic soil moisture monitor transmits the data to the controller at the water pump box, controlling the water pump to turn on. This achieves automatic irrigation of fruits and vegetables. Unlike irrigation based on experience or scheduled time, the electronic soil moisture monitor can automatically monitor soil moisture content in real time. Irrigation is only started when the soil moisture content is less than a preset value. This can accurately meet the water requirements of fruit and vegetable growth, eliminating the need for frequent manual checks of soil moisture and manual operation of irrigation equipment, saving labor costs, and to a certain extent helping to improve fruit yield and quality.

[0017] 2. This device, through its designed height adjustment mechanism, drives the threaded rod via a drive box, enabling the mounting bracket, along with the water pump box and water pipeline, to move up and down. This allows for electric adjustment of the irrigation height for melons and fruits, meeting the irrigation needs of different growth stages and varieties. It ensures that irrigation water is precisely applied to the roots or other parts of the plant, promoting growth and contributing to increased yield and quality of the melons and fruits.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Example 1, as Figure 1 As shown, an automatic irrigation device for fruit and vegetable cultivation includes a water supply pipe 1, an irrigation mechanism 2 installed on the rear side of the outer surface of the water supply pipe 1, installation mechanisms 3 symmetrically installed on the left and right sides of the outer surface of the water supply pipe 1, a humidity monitoring mechanism 4 installed at the bottom of each of the installation mechanisms 3, a water pump box 5 installed at the bottom of the water supply pipe 1, and a height adjustment mechanism 6 installed on the outer surface of the water pump box 5.

[0027] In this embodiment, the height adjustment mechanism 6 is fixed to the ground by an external fixing component, allowing it to support the water supply pipe 1 and other structures. The humidity monitoring mechanism 4 is then installed on the outer surface of the water supply pipe 1 via an installation mechanism 3. This installation mechanism facilitates quick and easy installation and removal of the humidity monitoring mechanism 4. The humidity monitoring mechanism 4 monitors the soil moisture content in real time. When the moisture content is less than a preset value, the controller inside the water pump box 5 activates the water pump, allowing the water supply pipe 1 to irrigate the fruits and vegetables in conjunction with the irrigation mechanism 2. When the electronic soil moisture monitor 402 detects that the soil moisture meets the preset value, the controller inside the water pump box 5 shuts off the water pump, stopping irrigation. The height adjustment mechanism 6 is driven by the drive box 7, allowing for vertical adjustment of the irrigation height, thus improving the applicability of the device.

[0028] For details, please refer to Figure 1 In this embodiment, a drive box 7 is installed on the top of the height adjustment mechanism 6, and a connecting water pipe 8 is installed at the front end of the water pump box 5;

[0029] Further reference Figure 1 and Figure 2 In this embodiment, the irrigation mechanism 2 includes several water pipes 201. A curved water pipe 203 is installed at the left end of the water conveying pipe 1. Sprinklers 202 are fixedly connected to the rear ends of the curved water pipe 203 and several water pipes 201. Sealing mounting seats 204 are installed at the ends of the curved water pipe 203 and several water pipes 201 near the water conveying pipe 1. Several sealing mounting seats 204 are fixedly connected to the water conveying pipe 1.

[0030] The irrigation system 2 includes several water pipes 201. A curved water pipe 203 is installed at the left end of the water conveying pipe 1. Both the curved water pipe 203 and the rear end of the water pipe 201 are connected to the nozzles 202. The end closest to the water conveying pipe 1 is fixedly connected to the water conveying pipe 1 through a sealing mounting seat 204. After the water pump is started, the water flows in the water conveying pipe 1, and is diverted through the sealing mounting seat 204 to the water pipes 201 and the curved water pipe 203. Finally, it is evenly sprayed from the nozzles 202 to the fruit and vegetable planting area.

[0031] Further reference Figure 1 , Figure 3 and Figure 4 In this embodiment, each of the several installation mechanisms 3 includes two clamps 301. The two clamps 301 are arranged symmetrically up and down. The clamp 301 at the lower end has a slot 302 symmetrically arranged in front and back. The inner surfaces of the two slots 302 are symmetrically connected to spring pieces 303. The opposite sides of the two spring pieces 303 are slidably connected to limit tooth plates 304. The opposite sides of the two limit tooth plates 304 are symmetrically arranged with limit telescopic plates 305. The other side of the limit telescopic plates 305 is installed on the inner wall of the slot 302.

[0032] The card holder 306 has a locking tooth installed on the outer side of one end near the inner end of the limiting tooth plate 304. When the card holder 306 is pressed down, the spring piece 303 is squeezed and extended, so that the card holder 306 can be locked into the slot 302 inside the clamp 301. When the card holder 306 is locked into the inner side of the slot 302, the spring piece 303 elastically rebounds and engages with the locking tooth at the limiting tooth plate 304 and the locking tooth on the outer side of the card holder 306 to achieve the effect of limiting and fixing the card holder 306. Thus, the card holder 306 can be fixed in place, and the two clamps 301 can be fixed to the outer surface of the water supply pipe 1.

[0033] Further reference Figure 3 and Figure 4In this embodiment, two limiting tooth plates 304 located on the same side of the same end are provided with a card seat 306 on opposite sides. The tops of the two card seats 306 are respectively fixedly connected to the front and rear sides of the bottom of the upper clamp 301 on the same side of the same end. The tops of several card slots 302 are symmetrically fixedly connected with top plates 307. The bottoms of several clamps 301 located at the lower end are fixedly connected with connecting plates 308. The rear end of the connecting plate 308 is fixedly connected with a control component 309. An electric telescopic rod 310 is installed on the inner side of the control component 309.

[0034] Further reference Figure 1 , Figure 3 and Figure 5 In this embodiment, each of the several humidity monitoring mechanisms 4 includes a support frame 401. An electronic soil moisture monitor 402 is installed on the inner side of the support frame 401, and a locking block 403 is symmetrically engaged on the lower side of the inner surface of the support frame 401.

[0035] The electronic soil moisture monitor 402 in the humidity monitoring unit 4 automatically monitors the moisture content in the soil in real time. Based on specific humidity sensing technology, the monitor converts soil moisture information into electrical signals. When the water content in the soil is less than the preset value, the sensor at the electronic soil moisture monitor 402 transmits the data representing soil moisture to the controller at the water pump box 5. The controller analyzes and processes the received data to determine whether irrigation needs to be started.

[0036] If irrigation is required, the water pump in the water pump box 5 is turned on under the command of the controller. Water is drawn from the water pipe 4 8, and sprayed out through the water delivery pipe 1 and the nozzle 202 of the irrigation mechanism 2 to achieve the effect of automatically irrigating the melons and fruits.

[0037] Through the designed humidity monitoring mechanism 4, the electronic soil moisture monitor 402 can automatically monitor the moisture content in the soil in real time. When the moisture content in the soil is less than the preset value, the sensor at the electronic soil moisture monitor 402 transmits the data to the controller at the water pump box 5 to control the water pump to turn on, thereby achieving the effect of automatic irrigation of melons and fruits. The electronic soil moisture monitor 402 can automatically monitor the soil moisture content in real time. Unlike irrigation based on experience or timed irrigation, irrigation is only started when the soil moisture content is less than the preset value. This can accurately meet the water requirements of melon and fruit growth, avoid root hypoxia and disease caused by over-irrigation, and growth inhibition caused by insufficient irrigation. There is no need for frequent manual checks of soil moisture and manual operation of irrigation equipment, saving labor costs and helping to improve fruit yield and quality to a certain extent.

[0038] Example 2: Based on Example 1, this example adds a height adjustment mechanism 6 to adjust the vertical height of the water supply pipe 1, irrigation mechanism 2, installation mechanism 3, humidity monitoring mechanism 4, and water pump box 5. By setting the height adjustment mechanism 6, the irrigation height of the melons and fruits can be electrically adjusted. By electrically adjusting the irrigation height, the irrigation needs of melons and fruits at different growth stages and different varieties can be met, ensuring that the irrigation water is accurately applied to the roots or the parts of the plant that need it.

[0039] For details, please refer to Figure 1 and Figure 6 In this embodiment, the height adjustment mechanism 6 includes an outer frame 601, a movable seat 602 is slidably connected to the inner surface of the outer frame 601, a threaded rod 603 is threadedly connected to the inner surface of the movable seat 602, protective ramps 604 are symmetrically fixedly connected to the lower side of the outer surface of the outer frame 601, and mounting brackets 605 are symmetrically fixedly connected to the outer surface of the movable seat 602. The mounting brackets 605 are installed on the outer surface of the water pump box 5, the drive box 7 is installed on the top of the outer frame 601, and the top of the threaded rod 603 is rotatably connected to the output end of the drive box 7.

[0040] The drive box 7 is installed on the top of the outer frame 601. The drive motor inside drives the threaded rod 603 to rotate. Since the movable seat 602 is threadedly connected to the threaded rod 603, and when the threaded rod 603 rotates, the movable seat 602 is limited by the outer frame 601 and can only slide up and down along its inner wall. The mounting bracket 605 connects the movable seat 602 and the water pump box 5, thereby enabling the mounting bracket 605 to move up and down with the water pump box 5 and the water pipeline 1, so as to achieve the purpose of electric adjustment of the irrigation height of melons and fruits.

[0041] The height adjustment mechanism 6 and drive box 7 drive the threaded rod 603, which enables the mounting bracket 605 to move up and down along with the water pump box 5 and water pipeline 1. This allows for electric adjustment of the irrigation height of the melons and fruits. By adjusting the irrigation height, the irrigation needs of different growth stages and varieties of melons and fruits can be met, ensuring that the irrigation water is accurately applied to the roots or the parts of the plant that need it, promoting growth and helping to improve the yield and quality of the melons and fruits.

[0042] The drive box 7 in this solution includes an existing mounting box, a drive motor, and a controller. The drive motor and controller are installed inside the mounting box. The controller here can be an existing motor controller that is compatible with the drive motor and can control the switching and rotation speed of the drive motor.

[0043] The water pump box 5 in this solution includes an outer casing, a water pump, and a PLC controller. The controller is linked with the humidity monitoring mechanism 4 and the drive box 7 to achieve automatic irrigation of fruits and vegetables. The PLC controller can be the Siemens S7-300 controller, which is a modular small PLC system that can directly control the equipment and monitor multiple lower-level programmable controllers. It is suitable for medium or large control systems and meets medium performance requirements.

[0044] The electronic soil moisture monitor 402 in this solution can be an existing electronic moisture monitor used to measure soil moisture.

[0045] The control component 309 in this solution includes a control box and a mounting frame as in the prior art. The control box is mounted on the top of the mounting frame. The control box further includes the mounting frame and an electric telescopic rod controller. The controller here can be the Dongyuxiang YMD602 from the prior art. Model: YMD602, voltage range: supports 12V / 24V / 36V / 48V, output power: 38W, load capacity 2000N, built-in limit switch, supports stroke control, supports communication with PLC, and is suitable for agricultural equipment.

[0046] In this scheme, the number of water pipes 201 can be gradually increased as the length of water pipeline 11 extends, thereby increasing the irrigation area.

[0047] Since the above devices are all very mature products in the prior art, they will not be described in detail in this application.

[0048] It should be noted that the specific installation method, circuit connection method and control method of the drive box 7 and water pump box 5 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0049] 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 illustrative of the principles of this 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 claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
