Description

Technical Field

[0001] This utility model relates to the field of seedling technology, and more specifically, to a tobacco seedling raising workbench. Background Technology

[0002] In today's tobacco production industry, the quality of the seedling stage directly affects the final yield and quality of tobacco leaves. Traditional tobacco seedling cultivation methods have long relied on simple seedbeds, but with industry development, their limitations have become increasingly apparent. From the sowing stage, manual operation is limited by human factors, making it difficult to ensure that the spacing and depth of seed sowing are maintained at a highly consistent level. This problem directly leads to uneven seedling growth in the early stages, making it difficult to standardize subsequent management work such as irrigation, fertilization, and pest and disease control, ultimately affecting the overall yield and quality uniformity of tobacco leaves.

[0003] Traditional seedbed techniques are inadequate in controlling the seedling environment. Tobacco seedlings have specific and precise requirements for environmental factors such as temperature, humidity, and light at different growth stages. For example, during seed germination, relatively high and stable humidity and suitable temperature are needed to promote rapid and uniform germination; while in the later stages of seedling growth, the duration and intensity of light have different requirements. However, traditional seedling methods often cannot accurately control these changes, resulting in poor growth environments and hindered development of tobacco seedlings.

[0004] In conclusion, there is an urgent need to develop a tobacco seedling cultivation workbench to meet the pressing demand of the modern tobacco industry for high-quality tobacco seedling cultivation, and to address the issues of improving the precision of manual operation and environmental control capabilities.

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 between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] See Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a tobacco seedling raising workbench, including:

[0039] The seedling box 100 has an opening for a storage compartment and a box door 170 on its side;

[0040] The seedling rack 400 is set inside the receiving chamber. The seedling rack 400 is equipped with two sets of seedling components. The two sets of seedling components are distributed vertically and vertically aligned with the support columns 410. The seedling components are detachably connected to the outer side of the support columns 410.

[0041] The irrigation mechanism 200 is located above the seedling rack 400. The irrigation mechanism 200 is equipped with a slider 250. A control valve 240 is fixedly connected to the lower surface of the slider 250. Three sets of nozzles 241 in different directions are provided on the lower surface of the control valve 240. The control valve 240 is connected to the water supply tank 230 through the water supply pipe 220. A water pump 280 is provided at the outlet of the water supply tank 230.

[0042] The heating mechanism 300 is located on the side of the seedling rack 400 and is used to heat the gas entering the seedling box 100.

[0043] Specifically, a support plate 150 is provided at the bottom of the container. The support plate 150 is convex in shape. Drainage holes 160 are provided on the low planes on both sides of the support plate 150. A first drive motor 420 is bolted to the bottom of the high plane of the support plate 150. The output end of the shaft of the first drive motor 420 is connected to the bottom of the support column 410.

[0044] As can be seen from the above, when cultivating seedlings, the seedling components are first detachably connected to the outer side of the support column 410. Since the two sets of seedling components are distributed vertically and aligned vertically, according to the actual seedling needs, seedling trays 452 are placed on the seedling components, and the potting soil is filled in and seeds are sown to complete the preliminary preparation work for seedling cultivation.

[0045] Start the water pump 280. The water pump 280 delivers water from the water supply tank 230 to the control valve 240 through the water supply pipe 220. The slider 250 can move above the seedling rack 400, which moves the control valve 240 and the nozzle 241 below it to the position of the seedling component that needs to be watered. The control valve 240 can control the flow of water. The three sets of nozzles 241 in different directions can water the seedling component from different angles to ensure that the seedling area receives a uniform water supply and meets the water needs of the seedlings.

[0046] When the temperature inside the seedling tray 100 is lower than the set value, the heating mechanism 300 is activated. The heating mechanism 300 heats the gas entering the seedling tray 100, maintaining a suitable temperature environment for seedling growth. If it is necessary to provide all-around lighting or other operations to the seedling components, the first drive motor 420 is activated. The shaft of the first drive motor 420 drives the support column 410 to rotate, thereby causing the seedling components connected to the outer side of the support column 410 to rotate as well. This facilitates operation of the seedling components in different positions and allows the seedlings to receive light and other conditions from different angles, promoting their uniform growth.

[0047] During the irrigation process, excess water will drip from the seedling components onto the support plate 150 at the bottom of the container. The drainage holes 160 on the low planes on both sides of the support plate 150 allow the waste liquid to flow out, making it easy to collect and treat, maintaining a clean environment inside the seedling box 100, and avoiding water accumulation that could adversely affect seedling growth.

[0048] Specifically, two support blocks 110 are symmetrically connected to the lower side of the seedling box 100, and the water supply tank 230 is fixed to the upper surface of the support block 110 on one side of the seedling box 100. A set of moving wheels 120 are fixed to the lower surface of both support blocks 110.

[0049] Understandably, the lower surfaces of the two support blocks 110 on the underside of the seedling box 100 are fixed with casters 120, allowing the entire seedling box 100 and related equipment to be easily moved. In practical applications, such as when the placement of the seedling box 100 needs to be adjusted according to different lighting conditions, temperature environments, or spatial layouts, it can be easily moved by simply pushing it, thus improving the flexibility of equipment use and space utilization efficiency.

[0050] Specifically, a waste liquid tank 130 is provided below the support plate 150. The waste liquid tank 130 is fixedly connected to the lower surface of the seedling box 100, and a sealing plug 140 is detachably connected to the side of the waste liquid tank 130.

[0051] Understandably, timely collection of waste liquid can effectively prevent prolonged contact between the liquid and the bottom of the seedling tray 100, avoiding corrosion and rust caused by water accumulation, thus extending the service life of the seedling tray 100. Furthermore, it prevents waste liquid from spilling and polluting the surrounding environment, providing a safe, hygienic, and stable working environment for seedling cultivation.

[0052] See Figure 4 As shown, the seedling assembly is provided with a connecting ring 430. Two sets of first rotary motors 470 are fixedly connected to the side of the connecting ring 430. The output ends of the shafts of the two sets of first rotary motors 470 are provided with rotating disks 440. Four seedling trays 452 are provided on the surface of each rotating disk 440. The seedling trays 452 are fixedly connected to the rotating disks through connecting rods 450. The connecting rods 450 are L-shaped. A gravity balancing device 451 is provided at the bend of the connecting rods 450. The connecting rods 450 and the gravity balancing device 451 are rotatably connected to ensure that the seedling trays 452 face upwards.

[0053] As can be seen from the above, the connecting rod 450 is L-shaped and a gravity balancing device 451 is installed at the bend, which is rotatably connected to the connecting rod 450. This ensures that no matter how the rotating disk 440 rotates, the seedling tray 452 always faces upward. This prevents the soil and seedlings in the seedling tray 452 from tipping over or falling due to the rotation of the rotating disk 440, ensuring the stability and continuity of the seedling cultivation work, avoiding damage to the seedlings caused by the tilting or flipping of the seedling tray 452, and improving the seedling success rate.

[0054] Understandably, the rotatable design of the rotating disc 440 allows for easy manipulation of specific seedling trays 452 when necessary (such as watering, fertilizing, or checking seedling growth), improving operational flexibility. Furthermore, this design adapts to varying environmental conditions such as light and temperature, allowing for adjustment of the orientation and position of the seedling trays 452 to achieve the optimal seedling environment.

[0055] Specifically, a slide rail 480460 is provided on the inner side of the connecting ring 430, and a slide rail is provided on the outer side of the support column 410. The slide rail and the slide rail 480460 are connected.

[0056] See Figure 5 As shown, the slider 250 is sleeved on the outside of the crossbar 251 and the screw 252. The screw 252 and the crossbar 251 are placed horizontally. The slider 250 is slidably connected to the crossbar 251, and the screw 252 is rotatably connected to the slider 250. The crossbar 251 is fixedly connected to the seedling box 100, and the screw 252 is rotatably connected to the seedling box 100. One end of the screw 252 passes through the seedling box 100 and is connected to the second drive motor 210. A transmission component is provided on the upper surface of the slider 250.

[0057] Specifically, the transmission assembly includes a worm gear 270 and a power unit. The worm gear 270 is fixedly connected to the shaft 271 and is located at the end of the shaft 271 away from the slider 250.

[0058] The power unit includes a support base 260, a worm gear 262, and a second rotary motor 261. The support base 260 is fixedly connected to the slider 250 and is located on the side of the slider 250 near the worm wheel 270. The worm gear 262 is rotatably connected to the support base 260 and meshes with the worm wheel 270. The second rotary motor 261 is mounted on the slider 250, and the worm gear 262 is fixedly connected to the output end of the shaft of the second rotary motor 261.

[0059] As can be seen from the above, when the entire system requires the shaft 271 to rotate or perform other related operations, the second rotary motor 261 is activated. The second rotary motor 261 serves as the power output end; its shaft begins to rotate after being energized. Since the worm 262 is fixedly connected to the output end of the shaft of the second rotary motor 261, the rotational motion of the shaft of the second rotary motor 261 is directly transmitted to the worm 262, causing the worm 262 to rotate around its own axis.

[0060] The worm 262 and worm wheel 270 mesh with each other, and the rotation of the worm 262 drives the worm wheel 270 to rotate. Because the worm wheel 270 is fixedly connected to the shaft 271 and is located at the end of the shaft 271 away from the slider 250, the rotation of the worm wheel 270 will synchronously drive the shaft 271 to rotate. The support base 260 is fixedly connected to the slider 250, and the slider 250 can move on a specific structure. When the slider 250 moves, it drives the pouring mechanism 200 below to move simultaneously.

[0061] Understandably, the worm gear 270 and worm 262 transmission possess unique self-locking characteristics, enabling precise and stable transmission when the worm 262 drives the worm gear 270. During operation, it effectively prevents the shaft 271 from reversing due to external interference or load changes, ensuring the stable operation of the components connected to the shaft 271. For example, in equipment requiring high positional accuracy, the stable rotation of the shaft 271 ensures the accuracy of related operations.

[0062] Specifically, the heating mechanism 300 includes: a fan 310, which is located on one side of the seedling box 100, at the corresponding end of the water supply tank 230, a support block 110 is connected to the bottom of the fan 310, and an air inlet plate 320 is provided on one side of the fan 310.

[0063] Heater 340 is disposed above fan 310, and fan 310 and heater 340 are connected by air inlet pipe 330;

[0064] The seedling box 100 has an exhaust port 350 on the other side corresponding to the heating mechanism 300, and a filter screen 360 is installed inside the exhaust port 350.

[0065] As can be seen from the above, when the temperature inside the seedling box 100 needs to be increased, the entire heating mechanism 300 starts to work. The support block 110 at the bottom of the fan 310 ensures that the fan 310 is placed stably, providing a foundation for its normal operation. When the fan 310 is powered on, the air intake plate 320 guides outside air into the fan 310. The air intake plate 320 can adjust the direction and speed of air intake to a certain extent, so that the air enters the fan 310 more smoothly.

[0066] The fan 310 draws in air and delivers it upward to the heater 340 through the air intake pipe 330. After the heater 340 is turned on, it heats the air passing through it, converting electrical energy into heat energy to raise the air temperature. The heated air is then output from the heater 340 and enters the seedling box 100 to raise the ambient temperature inside the seedling box 100 and create warm conditions for seedling growth.

[0067] As hot air continuously enters the seedling box 100, the air pressure inside the box increases, and some air will be discharged from the exhaust port 350 to prevent external pollutants from flowing back into the seedling box 100. The discharged air creates air circulation inside the seedling box 100, ensuring the freshness of the air and the uniformity of the temperature inside the box.

[0068] Specifically, the top of the seedling box 100 and the box body corresponding to the box door 170 are both made of light-transmitting material.

[0069] Understandably, the translucent material allows sunlight to fully penetrate the seedling box 100, providing ample light for the seedlings to meet their photosynthetic needs, which helps the seedlings grow vigorously and improves their quality and survival rate.

[0070] People can directly observe the growth of seedlings in the seedling box 100 through the light-transmitting part, such as seedling germination, growth height, leaf condition, etc., and promptly identify problems and take corresponding measures, such as adjusting environmental conditions such as light, temperature, and humidity, or carrying out pest and disease control.

[0071] It will be understood by those skilled in the art that the above description is merely 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.
