Description

Technical Field

[0001] This application relates to the field of seedling equipment technology, and more specifically, to a seedling raising device for forestry. Background Technology

[0002] Traditional forestry seedling cultivation mainly uses open-air seedbeds or simple greenhouses, which result in large fluctuations in temperature and humidity, and low efficiency in artificial irrigation and fertilization, making precise management difficult. In order to reduce energy consumption and improve seedling cultivation efficiency, forestry seedling cultivation equipment is often used.

[0003] The prior art publication CN220458058U provides a seedling raising device suitable for forestry seedling bases. This device can achieve the effect of cultivating seedlings by setting up an installation plate and a seedling trough. At the same time, through the set water storage tank and nozzles, the seedlings can be watered and nutrient solution replenished in a timely manner, which greatly accelerates the cultivation efficiency and reduces the cultivation cost.

[0004] While the existing technical solutions described above have improved seedling efficiency to some extent, they still have the following drawbacks: To increase the yield of seedlings per batch, workers often use multi-layer seedling cultivation methods as described in the above technical solutions. However, multi-layer three-dimensional seedling cultivation devices generally suffer from poor irrigation uniformity. The leaves of the upper seedlings retain a large amount of water, while the lower layers receive insufficient water, resulting in uneven water distribution. This not only wastes water resources but also seriously affects the survival rate of seedlings. In view of this, we propose a seedling cultivation device for forestry. Utility Model Content

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figure 1 and Figure 2 This application discloses a seedling raising device for forestry, comprising: a load-bearing frame 1, two drive chains 6 installed on the load-bearing frame 1, a driving mechanism installed on one side of the load-bearing frame 1, the driving mechanism being used to drive the drive chains 6 to rotate, a plurality of support plates 4 fixedly installed on each of the two drive chains 6, a placement box 3 installed between the two support plates 4, a lifting plate 8 fixedly installed on both sides of the placement box 3, the lifting plate 8 being constrained by the support plates 4 and rotatably connected to them, a plurality of seedling boxes 5 installed inside the placement box 3, and an irrigation mechanism installed above the load-bearing frame 1.

[0029] The driving mechanism includes two rotating rods 2 rotatably connected to the load-bearing frame 1. Both sides of the rotating rods 2 are fitted with sprockets 12, which are meshed with the drive chain 6. An electric motor 11 is fixedly installed on the load-bearing frame 1, and the output end of the electric motor 11 is connected and fixed to one of the rotating rods 2.

[0030] The irrigation mechanism includes a liquid distribution box 9 installed above the load-bearing frame 1. Multiple nozzles 10 are fixedly connected to the lower side of the liquid distribution box 9. A water pump 15 is installed on one side of the liquid distribution box 9. A connecting pipe 14 is fixedly connected between the output end of the water pump 15 and the liquid distribution box 9.

[0031] When watering is needed for the seedlings in the seedling tray 5, water enters the distribution box 9 under the action of the water pump 15 and is sprayed out through the nozzle 10. During this process, the motor 11 runs intermittently, and the rotating rod 2 drives the sprocket 12 to rotate. Since the sprocket 12 is meshed with the drive chain 6, the drive chain 6 then drives the seedling tray 5 to rise and fall intermittently, ensuring the uniform distribution of water during irrigation. This method effectively solves the problem of excessive water retention in the upper layer of seedling leaves and insufficient water intake in the lower layer in traditional multi-layer seedling devices, avoiding the risk of water waste and decreased seedling survival rate.

[0032] Reference Figure 1 and Figure 4 A sensing water outlet mechanism is also installed on one side of the liquid distribution box 9. The sensing water outlet mechanism includes an elastic telescopic rod 7 fixedly installed on the support plate 4. A ball bearing 16 is embedded at the end of the elastic telescopic rod 7. A pressure sensor 17 is fixedly installed on one side of the seedling box 5. The ball bearing 16 is in active contact with the pressure sensor 17. A solenoid valve 13 is installed on the connecting pipe 14. The solenoid valve 13, the water pump 15 and the pressure sensor 17 are all electrically connected to the external control mechanism.

[0033] During the intermittent lifting and lowering of the seedling box 5 driven by the drive chain 6, when the elastic telescopic rod 7 drives the ball bearing 16 to squeeze the pressure sensor 17, after reaching the pressure threshold, the solenoid valve 13 and the water pump 15 will start running under the control of the external control mechanism to irrigate the seedlings. When the ball bearing 16 disengages from the pressure sensor 17 and the seedling box 5 moves away from under the liquid distribution box 9, the solenoid valve 13 will close, the water pump 15 will stop running, and the nozzle 10 will stop spraying water. In this way, over-watering can be avoided, thereby achieving precise irrigation and improving water resource utilization.

[0034] Reference Figure 2 and Figure 3 The bottom of the seedling box 5 is densely covered with water-permeable holes 501, and the lower side of the placement box 3 is provided with a drainage groove 301. The drainage groove 301 and the water-permeable holes 501 can prevent excessive water accumulation in the seedling box 5, which would affect the normal growth of the seedlings.

[0035] This application effectively solves the problem of excessive water retention in the upper layer of seedling leaves and insufficient water intake in the lower layer in traditional multi-layer seedling raising devices by setting up a drive chain 6, a lifting plate 8, and a driving mechanism, thus avoiding the risk of water waste and reduced seedling survival rate. At the same time, by setting up an elastic telescopic rod 7, a solenoid valve 13, and a pressure sensor 17, it can avoid over-watering, thereby achieving precise irrigation and improving water resource utilization.

[0036] The implementation principle of a forestry seedling raising device according to this application embodiment is as follows: When relevant personnel use this technical solution for seedling raising, the motor 11 operates intermittently, the rotating rod 2 drives the sprocket 12 to rotate, and the drive chain 6 then drives the seedling box 5 to intermittently rise and fall. When the elastic telescopic rod 7 drives the ball bearing 16 to press the pressure sensor 17, after reaching the pressure threshold, under the control of the external control mechanism, the solenoid valve 13 and the water pump 15 then operate, and water enters the liquid distribution box 9 and is sprayed out through the nozzle 10 to irrigate the seedlings. This process is continued for an appropriate time to complete the seedling irrigation operation.
