Description

Technical Field

[0001] This utility model belongs to the field of greenhouse irrigation technology, specifically referring to an automatic irrigation machine for greenhouse vegetable cultivation. Background Technology

[0002] Greenhouses are closed or semi-closed environments where natural rainfall cannot enter. Vegetables require a continuous and stable supply of water for growth (such as leaf transpiration, flowering, and fruiting), and rely entirely on artificial irrigation. Otherwise, water shortage will lead to poor growth and reduced yield. Therefore, it is necessary to water the vegetables in the greenhouse regularly.

[0003] In existing technologies, watering vegetables in greenhouses is commonly done manually by spraying water onto the vegetables with a handheld hose. However, this method has drawbacks: it places a heavy workload on the workers and can easily result in uneven irrigation. Therefore, improvements are needed. Utility Model Content

[0004] The technical problem this invention aims to solve is that, in the prior art, manual irrigation is used to water vegetables in greenhouses, which is inefficient and prone to uneven irrigation.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: an automatic irrigation machine for greenhouse vegetable planting includes a greenhouse body, a groove plate is fixedly connected horizontally to the upper part of the greenhouse body, a slider is horizontally slidably arranged in the groove plate, a support plate is fixedly connected to the upper end of the slider, a lifting plate is vertically inserted through the support plate and the slider, an irrigation device is provided on the side wall of the greenhouse body and the lower end of the lifting plate, a left and right adjustment device is provided on the side wall of the groove plate and connected to the slider, and a lifting drive device is provided on the upper end of the support plate and connected to the lifting plate.

[0006] Furthermore, the left and right adjustment device includes a fixing plate, which is fixed to the middle of the side wall of the slot plate. A dual-axis motor is fixedly connected to the fixing plate, and a lead screw is provided at the output end of the dual-axis motor. An ear plate is horizontally fixed to the side wall of the slider and passes through the side wall of the slot plate and is threadedly connected to the lead screw.

[0007] Furthermore, the lifting drive device includes a vertical plate, which is disposed on the upper end surface of the support plate. A drive motor is fixedly connected to the vertical plate, and a gear is rotatably disposed between the vertical plates and poweredly connected to the drive motor. A rack is disposed in the lifting plate and meshes with the gear.

[0008] Furthermore, the irrigation device includes a water tank located outside the shed, a water pump mounted on the water tank, a flexible hose mounted on the water pump and passing through the shed, and an irrigation pipe horizontally fixed to the lower end of the lifting plate along the length of the shed and connected to the flexible hose, with drainage holes evenly distributed at the lower end of the irrigation pipe.

[0009] Furthermore, the rack is embedded in the lifting plate, and a baffle is provided at the upper end of the rack.

[0010] Furthermore, a limiting groove is provided on the side wall of the groove plate, and a limiting block matching the limiting groove is provided on the slider.

[0011] Furthermore, a control panel is provided on the shed body, and the control panel is connected to the dual-axis motor, the drive motor, and the water pump electrical control signal.

[0012] The beneficial effects achieved by adopting the above-described structure are as follows:

[0013] 1. This utility model features an irrigation device where a water pump draws water from a tank, delivers it through a hose to an irrigation pipe, and then drips it onto the vegetables through a drain hole, saving manpower for irrigation. A dual-axis motor drives a lead screw to rotate, which in turn drives sliders on both sides to slide in opposite directions within a trough, thus providing full coverage irrigation for the vegetables in the greenhouse. This results in more even irrigation and improved irrigation efficiency.

[0014] 2. This utility model, by setting up a lifting drive device, drives a motor to drive a gear to rotate, and the gear meshes with a rack to realize the lifting of the lifting plate, thereby driving the irrigation pipe to adjust its height. This allows it to adapt to irrigating vegetables of different heights and has a wide range of applications. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] like Figure 1-4 This utility model discloses an automatic irrigation machine for greenhouse vegetable cultivation, comprising a greenhouse body 1, a groove plate 2 fixedly connected horizontally to the upper part of the greenhouse body 1, a slider 3 horizontally slidably arranged in the groove plate 2, a support plate 4 fixedly connected to the upper end of the slider 3, a lifting plate 5 vertically penetrating the support plate 4 and the slider 3, an irrigation device 6 provided on the side wall of the greenhouse body 1 and the lower end of the lifting plate 5, a left and right adjustment device 8 provided on the side wall of the groove plate 2 and connected to the slider 3, and a lifting drive device 7 provided on the upper end of the support plate 4 and connected to the lifting plate 5.

[0023] like Figure 1-2 The left and right adjustment device 8 includes a fixing plate 9, which is fixed to the middle of the side wall of the trough plate 2. A dual-axis motor 10 is fixedly connected to the fixing plate 9. A lead screw 11 is provided at the output end of the dual-axis motor 10. An ear plate 12 is horizontally fixed to the side wall of the slider 3 and passes through the side wall of the trough plate 2 and is threadedly connected to the lead screw 11. A limit groove 23 is provided on the side wall of the trough plate 2. A limit block matching the limit groove 23 is provided on the slider 3 to ensure that the slider 3 slides smoothly. The ear plate 12 is driven to slide in the trough plate 2 by the rotation of the lead screw 11, so that the slider 3 can slide left and right in the trough plate 2 to adjust the irrigation range, make the irrigation more uniform, and improve the irrigation efficiency.

[0024] like Figure 1-4 The lifting drive device 7 includes a vertical plate 13, which is disposed on the upper end surface of the support plate 4. A drive motor 15 is fixedly connected to the vertical plate 13. A gear 14 is rotatably disposed between the vertical plates 13 and is poweredly connected to the drive motor 15. A rack 16 is disposed in the lifting plate 5 and meshes with the gear 14. The rack 16 is embedded in the lifting plate 5, and a baffle 22 is disposed at the upper end of the rack 16 to prevent the gear 14 from disengaging from the rack 16. By the gear 14 meshing with the rack 16, the lifting plate 5 can slide up and down, thereby adjusting the watering height.

[0025] like Figure 1-3 The irrigation device 6 includes a water tank 17, which is located outside the greenhouse 1. A water pump 18 is installed on the water tank 17, and a hose 19 is installed on the water pump 18 and passes through the greenhouse 1. The lower end of the lifting plate 5 is horizontally fixed to an irrigation pipe 20 along the length of the greenhouse 1 and is connected to the hose 19. The lower end of the irrigation pipe 20 is evenly distributed with drainage holes 21. Water is pumped by the water pump 18 and delivered to the irrigation pipe 20. Water can be evenly irrigated on the vegetables through the drainage holes 21.

[0026] A control panel 24 is installed on the shed body 1. The control panel 24 is connected to the electrical control signals of the dual-axis motor 10, the drive motor 15, and the water pump 18.

[0027] In practical use, the water tank 17 is filled with clean water, and the water pump 18 draws water from the water tank 17 and delivers it to the irrigation pipe 20 through the hose 19. The lower end of the irrigation pipe 20 is evenly distributed with leakage holes 21, which can evenly drip water onto the vegetables below. By starting the dual-axis motor 10, the dual-axis motor 10 drives the lead screws 11 on both sides to rotate. The lead screws 11 drive the ear plates 12 to slide in the side wall of the trough plate 2, thereby driving the sliders 3 to slide towards each other in the trough plate 2. Thus, the irrigation pipe 20 can be adjusted to water left and right until it covers all the vegetables, which greatly improves the irrigation efficiency and saves manpower.

[0028] When it is necessary to adjust the watering height of the irrigation pipe 20, the drive motor 15 drives the gear 14 to rotate. The gear 14 meshes with the rack 16, causing the lifting plate 5 to slide vertically in the slider 3. Thus, the lifting plate 5 can pull the irrigation pipe 20 to adjust its height, adapting to the irrigation of vegetables at different heights and making it more widely applicable.

[0029] It should be noted that the dual-shaft motor 10, drive motor 15 and water pump 18 involved in the solution all need to be connected to the power supply via cables and centrally controlled through the control panel 24. The control panel 24 is equivalent to a switch. This is existing technology, and those skilled in the art can clearly understand its principle and use it, so it will not be described in detail here.

[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
