Abstract
Description
Technical Field
[0001] This utility model relates to the field of vegetable planting technology, and in particular to a drip irrigation device for vegetable planting. Background Technology
[0002] With the continuous advancement of agricultural modernization, the demand for refined and automated water and fertilizer management in vegetable cultivation is increasing. Drip irrigation equipment, as a crucial tool for achieving precision agriculture, can deliver water and nutrients to the root zone of crops on demand and in precise quantities, thereby improving water and fertilizer utilization efficiency, reducing resource waste, and promoting healthy crop growth. This type of equipment is widely used in various vegetable cultivation scenarios, including greenhouses, open fields, and vertical farming, and has become one of the key supporting equipment in modern facility agriculture.
[0003] Existing drip irrigation systems for vegetable cultivation typically consist of a water storage device, a fertilization system, a pipeline network, and a control system. Irrigation and fertilization are accomplished through drippers or sprinklers. The water-fertilizer mixture is delivered to the root zone of the vegetables at regular intervals and in measured quantities along the pipeline under a certain pressure. However, in existing technologies, the drippers are usually fixed in position on the equipment beam, making adjustment inconvenient and difficult to adapt to different row or plant spacing. This results in a mismatch between the dripper position and the plant root system during irrigation, leading to water and fertilizer waste and affecting the uniform absorption and growth of the crops. Therefore, this paper proposes a drip irrigation system for vegetable cultivation to address these problems. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a drip irrigation device for vegetable planting, which aims to improve the problem that the position of the drippers on the crossbeam of the device is usually fixed or inconvenient to adjust in the existing technology.

[0028] 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.
[0029] Reference Figures 1-3 This utility model provides an embodiment of a drip irrigation device for vegetable cultivation, comprising a crossbeam 1, which serves as the main support for the drip irrigation device. The crossbeam 1 is horizontally mounted above the vegetable planting area, providing a stable load-bearing structure. A sliding ring 2 is slidably connected to the side wall of the crossbeam 1, allowing free movement along the length of the crossbeam 1 to adjust according to the planting spacing of the crops. This adapts to the planting needs of different types of vegetables, exhibiting good compatibility. A dripper 3 is located at the bottom of the sliding ring 2, used to evenly and slowly release the water-fertilizer mixture to the vegetable roots, improving water and fertilizer utilization and preventing resource waste. A connecting pipe 4 is fixedly connected inside the dripper 3, communicating with a water supply or fertilizer delivery device. The crossbeam 1 is equipped with a positioning mechanism to precisely fix the dripper 3 in the appropriate position, preventing... To prevent dripper position displacement due to vibration or external interference and ensure irrigation uniformity, an adjustment mechanism is provided on the side wall of the crossbeam 1. The positioning mechanism includes a positioning block 6 and a recessed hole inside the sliding ring 2. A sleeve 5 is fixedly connected inside the crossbeam 1. The positioning block 6 is slidably connected inside the sleeve 5. The sleeve 5 provides sliding guidance for the positioning block 6 and restricts its movement direction to enhance structural stability. A spring 7 is provided inside the sleeve 5. The positioning block 6 is slidably connected inside the recessed hole. One end of the spring 7 is fixedly connected inside the sleeve 5, and the other end of the spring 7 is fixedly connected to the side wall of the positioning block 6. The spring 7 provides elastic support so that the positioning block 6 is always in the pop-out state when not subjected to external force and automatically embedded in the recessed hole, playing an automatic locking role. This facilitates quick installation and fixing of the dripper position by the user. The sleeves 5 are evenly distributed inside the crossbeam 1.
[0030] Reference Figures 1-3The adjustment mechanism includes a fixed cylinder 8 and a sliding rod 9. The fixed cylinder 8 is located on both sides of the crossbeam 1, and the sliding rod 9 is slidably connected inside the fixed cylinder 8. It can reciprocate along the axial direction of the fixed cylinder 8 to adjust the height. A wing bolt 11 is threaded inside the sliding rod 9. The position of the sliding rod 9 can be locked and released by rotating the wing bolt 11. A washer 12 is provided on the outside of the wing bolt 11. A guide groove 10 is opened through the inside of the fixed cylinder 8. The wing bolt 11 is located inside the guide groove 10. The washer 12 is located between the end of the wing bolt 11 and the fixed cylinder 8. In the locked state, the washer 12 fits against the fixed cylinder 8, which effectively increases the contact area, enhances the locking force, and prevents the mechanism from loosening or shifting during use. A mounting plate 13 is fixedly connected to the top wall of the fixed cylinder 8 for connecting with external structures or devices, enhancing the installation flexibility and adaptability of the entire adjustment mechanism. A connecting block 14 is fixedly connected between the crossbeam 1 and the sliding rod 9 to ensure the synchronous movement of the crossbeam 1 and the adjustment mechanism.
[0031] Working principle: When using this equipment, first connect the water and fertilizer delivery pipe to the connecting pipe 4, and drip irrigate the vegetables below through the dripper 3. During use, the position of the dripper 3 can be adjusted according to the spacing of the vegetable planting. By sliding the sliding ring 2, it can be moved on the crossbeam 1, and by squeezing the positioning block 6, it can be moved into the inside of the sleeve 5, while the spring 7 is deformed. When the concave hole inside the sliding ring 2 moves to the top of the positioning block 6, the spring 7 loses the squeezing force and pushes the positioning block 6 upward to reset, thus locking it inside the concave hole and fixing the current position of the sliding ring 2.
[0032] When using the equipment, if it is necessary to adjust the height of the dripper 3 according to the growth height of the vegetables, the pressure on the gasket 12 can be released by twisting the wing bolt 11. At this time, the slide rod 9 can slide inside the fixed cylinder 8, thereby changing the distance between the dripper 3 and the vegetables. After the distance is adjusted, the wing bolt 11 is rotated in the opposite direction to reapply pressure to the gasket 12, so that it is tightly attached to the outside of the fixed cylinder 8, thereby fixing the position of the slide rod 9 and ensuring the height of the dripper 3.
[0033] 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.
