Description

Technical Field

[0001] The present invention relates to the technical field of seedling raising, and particularly to a seedling raising device for preventing the roots of forest container seedlings from piercing through the bags. Background Art

[0002] In the process of modern forestry seedling raising, the container seedling raising technology has been widely used in large-scale afforestation and ecological restoration projects due to its advantages such as flexible land use, convenient transportation, and high seedling survival rate. Especially in the forest nursery cultivation stage, how to construct a microenvironment suitable for the root development of seedlings and achieve efficient seedling emergence through automated operation has become the key development direction of containerized seedling raising technology. Based on this demand, researching and developing a seedling raising device with functions of breathable root protection, anti-piercing of bags, and convenient seedling taking has important engineering value and practical significance for improving the seedling outplanting rate and the efficiency of standardized seedling raising.

[0003] In the prior art, plastic seedling raising containers with closed bottoms or plug tray structures with leakage holes are mostly used as seedling raising carriers, and the interior is filled with culture substrates (such as peat soil or mixed substrates), and seedling cultivation is completed by manual sowing or planting. To ensure root ventilation, most devices are provided with a number of exhaust holes at the bottom of the container, or indirect ventilation is achieved by suspending the tray, and at the same time, some solutions adjust the microclimate of the seedbed by adding a shading film, a humidity control system, or a circulation fan.

[0004] However, the above-mentioned traditional structures still face prominent problems in long-term use, that is, the roots of seedlings are prone to penetrate through the ventilation holes at the bottom of the container or break through the film and extend outside the container, forming a phenomenon of piercing through the bags, resulting in serious root breakage and seedling damage, and ultimately affecting the survival rate and outplanting quality. In addition, some structures have not fully solved the problem of natural separation of roots and substrates, resulting in low efficiency of seedling taking operations and high labor intensity, which seriously restricts the automation and efficiency improvement of large-scale seedling raising operations. How to construct a structural system that can effectively inhibit root piercing through the bags and facilitate rapid seedling emergence has become a key technical problem that urgently needs to be solved in the current forest container seedling raising device.

[0028] Working principle: when it is necessary to use the seedling raising device for seedling raising operations, first, the hollow tube 11 is laid with soil, and then the seedlings are placed inside the soil. After the telescopic rod 23 is compressed by pulling the sliding plate 20, the block 21 is separated from one side of the external rack 14, and then the knob 19 is turned to make the gear 18 mesh and rotate with the external rack 14, thereby driving the connecting rod 16 inside the connecting ring 13 to move, and then the connecting rod 16 drives the limiting plate 15 to slide within the hollow tube 11 within a limited position. Through the movement of the limiting plate 15, the arc-shaped hollow plate 17 is driven to adjust the internal volume of the hollow tube 11 according to the use requirements. When water is applied inside the soil, it flows into the top of the box body 31 through the internal holes of the hollow tube 11, and is discharged into the box body 31 through the through holes 32 for storage. The impurities are filtered through the filter box 28 to achieve the effect of filtering sewage. At this time, the filtered water can be reused through the cooperation of the drain pipe 29 and the valve 30. The impurities can be cleaned by pulling out the filter box 28. During the seedling cultivation process, the fan 26 is started, and the external air is filtered through the dust cover 27 and discharged into the space between the box body 31 and the fixed plate 2 by the fan 26, thereby achieving the effect of ensuring the air permeability of the seedling root system. When the seedling cultivation is completed, the rotating card plate 9 is disengaged from the inside of the buckle 10 by rotating. At this time, the reaction force of the spring 5 is used to drive the J-shaped rod 4 to slide within the L-shaped bracket 3, and then the J-shaped rod 4 drives the push plate 7 to quickly push the seedling soil out of the hollow cylinder 11, thereby achieving the effect of quickly removing the seedling.
