Description

Technical Field

[0001] This invention relates to the field of forestry cultivation technology, and in particular to an automatic irrigation device for cultivating forestry seedlings. Background Technology

[0002] In the process of cultivating forestry seedlings, scientific and reasonable irrigation and fertilization are key links to ensure the healthy growth of seedlings. In the early stage of growth, seedlings are particularly sensitive to the demand for water and nutrients. Traditional manual irrigation and fertilization methods have problems such as low efficiency, high labor intensity and waste of resources. Especially in large-scale seedling cultivation, manual operation is difficult to guarantee the uniformity of irrigation and the precision of fertilization, which can easily lead to uneven seedling growth and even affect the survival rate due to local over-watering or fertilizer damage.

[0003] While existing automatic irrigation equipment has alleviated reliance on manual labor to some extent, it still has many limitations. First, traditional automatic irrigation devices lack precision in water flow control, which can easily lead to localized waterlogging or drought. Furthermore, the spraying range is fixed and cannot adapt to the needs of different seedbed layouts. Second, most devices have limited functionality, only capable of basic watering and lacking integration with fertilization systems. This makes it difficult to manage water and fertilizer in a coordinated manner and achieve precise proportions. In addition, the fertilization process in existing technologies largely relies on manual labor or independent machinery, making it difficult to accurately control the amount of fertilizer applied, which can easily lead to uneven fertilization or waste.

[0048] Working principle: The automatic irrigation device for forestry seedling cultivation of the present invention realizes the automated coordinated operation of irrigation and fertilization through mechanical linkage. The water in the water tank 23 is pressurized by the booster pump 25 through the connecting pipe 24 and then transported to the rotating irrigation component 32 through the output pipe 26. The shaft 311 of the drive component 31 is driven by the transmission between the main wheel 312 and the pulley 313, and drives the pulley 315 to rotate through the synchronous belt 316, thereby driving the rotating shaft 323 to rotate. The rotating bar 324 at the left end of the rotating shaft 323 is connected to the rotating component 32 through the connecting arm 325. The linkage of 6 causes the worm gear 329 and worm 328 to mesh and drive, ultimately driving the diverter 3210 and water pipe 3211 to rotate at a constant speed around the axis of the worm 328, achieving wide-angle and uniform spraying from the spray nozzle 3212. The pulley 635 at the left end of the shaft 311 drives the pulley 634 through the synchronous belt 636, driving the main rod 631 to rotate. The toothed gear 632 on the main rod 631 meshes with the rack 618 at the front end of the door 617. Through the intermittent rotation of the toothed gear 632, the door 617 is controlled to move between the limit bars 616. The sliding mechanism periodically opens the hopper 615, allowing fertilizer to flow from the storage hopper 612 into the fertilizer accumulation chute 614. The sprocket 2 624 at the right end of the shaft 311 drives the sprocket 1 623 via the chain 625, causing the rotating rod 621 and the quantitative fertilizer dispensing wheel 622 to rotate. The grooved structure of the quantitative fertilizer dispensing wheel 622 quantitatively extracts fertilizer from the fertilizer accumulation chute 614, which falls through the fertilizer outlet hopper 613 into the conveying pipe 7. Finally, through the cooperation of the soil-distributing fertilizer cylinder 8 and the soil-collecting component 9, the fertilizer is precisely buried in the soil. The push rod 4 is linked with the control gate 5, and adjustments are made accordingly. The contact position between the main wheel 312 and the control gate 5 controls the movement of the device. The device synchronously distributes the power of the drive component 31 to the irrigation and fertilization mechanism through the mechanical transmission system, ensuring the timing and amount of water and fertilizer application, and avoiding resource waste. This device achieves precise synchronous control of water and fertilizer through a purely mechanical structure, eliminating the need for a complex electrical control system, thus reducing energy consumption and maintenance costs. The rotary spraying and quantitative fertilization design adapts to different terrains and seedling distribution needs, significantly improving seedling efficiency and survival rate, and is suitable for large-scale forestry production scenarios.
