Description

Technical Field

[0001] This application relates to the technical field of tobacco seedling cultivation, and in particular to an irrigation device for flue-cured tobacco seedling transplanting. Background Technology

[0002] Transplanting is a two-stage seedling raising method. First, seeds are sown in a mother bed. Once the tobacco seedlings have developed a certain number of true leaves, they are transplanted to ordinary seedbeds, nutrient bags, or nutrient trays for further cultivation until they become robust seedlings suitable for field transplanting. This method is effective in preventing premature flowering of flue-cured tobacco due to low temperatures caused by premature transplanting. Currently, manual sprinkler irrigation is commonly used in the transplanting stage of flue-cured tobacco, supplemented by humidity sensors to allow for manual adjustment of irrigation volume and frequency, reducing water waste. Intelligent temperature and humidity controllers maintain suitable environmental conditions for transplanting, thereby improving the efficiency of transplanting.

[0003] However, in traditional drip irrigation, water droplets often fall through the same point, which can easily cause the soil to shift due to different water absorption rates. At the same time, the roots of tobacco plants tend to grow towards the water droplet, which can lead to soil loss near the irrigation point, affecting the growth of the roots and causing poor growth of tobacco seedlings. Utility Model Content

[0004] Therefore, it is necessary to provide an irrigation device for flue-cured tobacco seedling cultivation to address the problem that the single location of drip irrigation affects the growth of tobacco seedlings.

On this basis, open the irrigation water tank so that the water in the irrigation water tank flows into the water flow channel of the irrigation support. The water flows into the drip irrigation component along the water flow channel so that the water can drip into the soil of the tobacco seedling through the drip irrigation component.

[0037] See Figure 1 and Figure 3 This application presents an embodiment of a flue-cured tobacco seedling irrigation device 100, which includes an irrigation water tank 10, an irrigation support 20, an irrigation seat 30, a drip irrigation component 40, and a drive mechanism 50.

[0038] The irrigation tank 10 specifically includes a tank body and a tank cover. The tank cover is hinged and installed at the opening on the top of the tank body to allow water to be added to the tank body.

[0039] The bottom of the tank is equipped with multiple casters to facilitate the movement of the irrigation tank 10, allowing for flexible switching between the water replenishment position and the irrigation working position.

[0040] Please continue reading. Figure 1 and Figure 3 The irrigation support 20 has a water flow channel 21 inside, which is connected to the irrigation water tank 10. The irrigation seat 30 is fixedly connected to the irrigation support 20. The irrigation seat 30 has a rotating cavity 31 inside and a receiving cavity 32 outside, which is used to hold the tobacco seedlings. The drip irrigation component 40 is rotatably disposed in the rotating cavity 31. The drive mechanism 50 is disposed on the irrigation support 20 and is connected to the drip irrigation component 40 for transmission, so as to drive the drip irrigation component 40 to rotate around the tobacco seedling.

[0041] In summary, implementing the technical solution of this embodiment will achieve the following beneficial effects: When using the flue-cured tobacco seedling irrigation equipment 100 of this solution, the position of the irrigation support 20 is adjusted so that the irrigation seat 30 surrounds the outside of the tobacco seedling, that is, the tobacco seedling is in the center of the receiving cavity 32; on this basis, the irrigation water tank 10 is opened so that the water in the irrigation water tank 10 flows into the water flow channel 21 of the irrigation support 20, and the water flows into the drip irrigation component 40 along the water flow channel 21, so that the water can be dripped into the soil of the tobacco seedling through the drip irrigation component 40. Then, the drive mechanism 50 is started, and the drive mechanism 50 drives the drip irrigation component 40 to rotate in the rotating cavity 31. The drip irrigation component 40 rotates around the tobacco seedling in a circumferential direction, so that the drip irrigation component 40 can evenly drip water to different positions of the soil around the tobacco seedling, avoid the root system of the tobacco seedling from growing off-center, and prevent the problem of poor growth of the tobacco seedling.

[0042] In one embodiment, the flue-cured tobacco seedling irrigation equipment 100 further includes a water outlet pipe 60 and a water pump 70. The water inlet of the water outlet pipe 60 is connected to the water outlet of the irrigation water tank 10, the water outlet of the water outlet pipe 60 is connected to the water inlet of the water pump 70, the water outlet of the water pump 70 is connected to the water flow channel 21, and the water pump 70 is used to electrically connect to a humidity sensor.

[0043] Please continue reading. Figure 1During operation, water in the irrigation tank 10 flows into the water pump 70 through the outlet pipe 60, and then the water pump 70 provides the power source to continuously flow into the water flow channel 21, meeting the drip irrigation needs of the tobacco seedlings. Furthermore, the water pump 70 is connected to a humidity sensor. Based on the real-time monitoring of ambient humidity by the humidity sensor, the water pump 70 can flexibly control the water flow rate delivered into the water flow channel 21, thereby ensuring that the amount of water dripped into the soil of the tobacco seedlings is appropriate and guaranteeing the safe growth of the tobacco seedlings.

[0044] Please continue reading. Figure 2 and Figure 3 In another embodiment, the drive mechanism 50 includes a drive motor 51 and a transmission assembly 52, the drip irrigation assembly 40 includes a drip irrigation disc 41 and a drip irrigation pipe 42, the drive motor 51 is connected to the transmission assembly 52, the transmission assembly 52 is rotatably disposed inside the water flow channel 21, the drip irrigation disc 41 is rotatably disposed inside the rotating cavity 31 and is connected to the transmission assembly 52, and the drip irrigation pipe 42 is mounted on the drip irrigation disc 41 and can rotate circumferentially around the tobacco seedling.

[0045] During irrigation, the drive motor 51 drives the transmission component 52 to rotate, and the transmission component 52 synchronously drives the drip irrigation disc 41 to rotate, so that the drip irrigation disc 41 drives the drip irrigation pipe 42 to rotate around the tobacco seedling in a circumferential direction, so as to evenly drip water into the soil in the circumferential direction of the tobacco seedling and prevent the roots of the tobacco seedling from growing off-center.

[0046] More specifically, the transmission assembly 52 includes a first transmission wheel 521, a transmission component 522, and a second transmission wheel 523. The drive motor 51 is connected to the first transmission wheel 521. The first transmission wheel 521 and the second transmission wheel 523 are arranged at intervals along the first direction of the irrigation bracket 20. The transmission component 522 is sleeved on the outside of the first transmission wheel 521 and the second transmission wheel 523. The transmission component 522 is connected to the drip irrigation disc 41.

[0047] That is, the drive motor 51 directly drives the first transmission wheel 521 to rotate, and the first transmission wheel 521 then drives the second transmission wheel 523 to rotate synchronously through the transmission component 522. The first transmission wheel 521 and the second transmission wheel 523 tension and support the transmission component 522, so that the transmission component 522 can drive the drip irrigation disc 41 to rotate, realizing the ring drip irrigation of the drip irrigation pipe 42. The transmission component 52 has a simple structure and stable and reliable operation.

[0048] For example, both the first transmission wheel 521 and the second transmission wheel 523 are sprockets, and the transmission component 522 is a chain. In this case, the transmission assembly 52 is specifically a sprocket mechanism. Of course, in other optional embodiments, the transmission assembly 52 can also be a synchronous belt pulley mechanism, etc., and can be flexibly selected according to actual needs.

[0049] Understandably, in the above embodiment, the transmission component 522 drives the drip irrigation disc 41 to rotate through friction.

[0050] Please continue reading. Figure 3 and Figure 4 To prevent slippage from affecting the driving efficiency of the transmission component 522 on the drip irrigation tray 41, in one embodiment, the transmission component 522 is provided with a plurality of actuating teeth 524, which are arranged along the rotation direction of the transmission component 522. The drip irrigation tray 41 is provided with a plurality of mating teeth 411, which are arranged in the circumferential direction of the drip irrigation tray 41. The actuating teeth 524 abut against the mating teeth 411.

[0051] That is, by means of the meshing of the actuating tooth 524 and the mating tooth 411, the actuating tooth 524 can reliably actuate the mating tooth 411, thereby driving the drip irrigation disc 41 to rotate, effectively preventing slippage due to insufficient friction, and ensuring the working efficiency of the drip irrigation pipe 42 and the uniformity of water drip irrigation.

[0052] Please continue reading. Figure 2 Furthermore, based on any of the above embodiments, multiple drip irrigation components 40 are provided, and the multiple drip irrigation components 40 are arranged side by side at intervals along the first direction of the irrigation support 20 on the same side or opposite sides of the transmission component 52. In this way, the multiple drip irrigation components 40 can be driven simultaneously by the transmission component 52 to rotate synchronously, so that the multiple drip irrigation components 40 can simultaneously achieve uniform drip irrigation and nurturing of multiple tobacco seedlings, thereby improving the working capacity of the flue-cured tobacco transplanting seedling irrigation equipment 100.

[0053] The first direction specifically refers to Figure 2 The direction of arrow S1 in the diagram.

[0054] Furthermore, in another embodiment, the drive mechanism 50 further includes a linkage 53, and at least two transmission components 52 are provided. The at least two transmission components 52 are arranged side by side at intervals along the second direction of the irrigation bracket 20. Adjacent transmission components 52 are connected by a linkage 53. Each transmission component 52 has a plurality of drip irrigation components 40 on one side.

[0055] In this way, the linkage 53 can realize the linkage of at least two transmission components 52, thereby realizing the linkage rotation of multiple drip irrigation components 40, meeting the needs of large-scale planting for simultaneous drip irrigation of more tobacco seedlings, further improving the working capacity of irrigation equipment, reducing the number of irrigation equipment required, and lowering costs.

[0056] The second direction specifically refers to Figure 2 The direction of the middle arrow S2.

[0057] Please continue reading. Figures 3 to 5Furthermore, based on any of the above embodiments, the flue-cured tobacco seedling irrigation equipment 100 also includes a blockage-clearing mechanism 80. The blockage-clearing mechanism 80 is disposed on the drip irrigation tray 41 and located within the rotating cavity 31. The blockage-clearing mechanism 80 is configured to cooperate with the drip irrigation pipe 42. An actuating part is provided on the side wall of the rotating cavity 31, and the actuating part is in transmission cooperation with the blockage-clearing mechanism 80 to drive the blockage-clearing mechanism 80 to clear the drip irrigation pipe 42. With the continuous rotation of the drip irrigation tray 41, the blockage-clearing mechanism 80 can periodically clear the drip irrigation pipe 42, preventing the drip pipe from becoming clogged and thus preventing normal drip irrigation of the tobacco seedling soil.

[0058] Specifically, in one optional embodiment, the triggering part is provided as a ramp surface 312, and the side wall of the rotating cavity 31 is also provided with a control groove 311. The edge of the control groove 311 is provided with a ramp surface 312. The unblocking mechanism 80 includes a control block 81, a pressure pipe 82, a push-pull rod 83 and an unblocking push plate 84. One end of the pressure pipe 82 is fixed on the drip irrigation tray 41. The control block 81 is movably connected to the inner wall of the pressure pipe 82. The push-pull rod 83 is movably inserted into the other end of the pressure pipe 82. The end of the push-pull rod 83 extending out of the pressure pipe 82 is connected to the unblocking push plate 84. The unblocking push plate 84 can extend into or out of the cavity of the drip irrigation pipe 42.

[0059] As the drip irrigation tray 41 rotates, when the control block 81 moves above the slope surface 312, it moves upward and inserts into the air pressure pipe 82, increasing the air pressure inside the pipe. This increases the pressure, pushing the push rod 83 downward. The push rod 83 then pushes the unblocking plate 84 into the drip irrigation pipe 42 to remove impurities clogging the pipe. When the control block 81 slides off the slope surface 312, it disengages from the air pressure pipe 82, reducing the air pressure and creating suction on the push rod 83. This causes the push rod 83 to pull the unblocking plate 84 out of the pipe, ensuring that water from the drip irrigation tray 41 flows normally into the pipe 42 for drip irrigation.

[0060] Furthermore, the unblocking mechanism 80 also includes an elastic element 85. One end of the elastic element 85 is connected to the inner wall of the air pressure pipe 82, and the other end of the elastic element 85 is connected to the control block 81. When the control block 81 slides down the slope surface 312, the elastic element 85 simultaneously applies an elastic thrust to the control block 81, ensuring that the control block 81 reliably disengages from the air pressure pipe 82, and preventing the problem of the push-pull rod 83 being unable to pull the unblocking push plate 84 out of the drip irrigation pipe 42, thus blocking the drip irrigation pipe 42.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
