[0026] By adopting the above technical solution, the installation of water pipe 42 is convenient, making it easy to replace later and improving the quality of spraying.

[0027] Specifically, the adjusting device 46 includes a guide frame 464, which is fixedly connected to one side surface of the support base 44. A drive motor 466 is fixedly connected to the bottom end of the guide frame 464. A lead screw 465 is connected to the output end of the drive motor 466. A movable rod 461 is connected to the surface of the lead screw 465. An installation groove 462 is opened at the upper end of the movable rod 461. A positioning bolt 463 is threadedly connected inside the installation groove 462.

[0028] By adopting the above technical solution, when spraying different seedling trays, the adjustable water pipe 42 can be positioned to raise the height of the spray pipe 41 to prevent it from obstructing the seedling trays. Simultaneously, two sets of drive motors 466 are turned on to rotate the lead screw 465. At this time, the movable rod 461 moves upward along the inside of the guide frame 464, and at the same time pushes the water pipe 42 at the upper end of the movable rod 461 upward, ensuring the convenience of adjusting the height of the spray pipe 41 so as to avoid the seedling trays and improve the stability of the spraying operation.

[0029] Specifically, a snap-fit ​​seat is fixed to the upper side of the guide frame 464 corresponding to the support seat 44, and a damping pad is fitted inside the snap-fit ​​seat.

[0030] By adopting the above technical solution, the guide frame 464 can be installed on the upper side of the support base 44 through the snap-fit ​​seat, and the installation position of the guide frame 464 can be easily adjusted to improve the applicability of the equipment.

[0031] In this embodiment, when the seedling tray passes the upper end of the seedling tray conveyor belt 2, water is supplied to the water pipe 42 through the connecting pipe 45. At the same time, water is sprayed from the bottom end of the spray pipe 41 to humidify the coated seeds in the seedling tray, improve the seed germination rate, and ensure the cultivation quality of tobacco.

[0032] When spraying different seedling trays, the adjustable water pipe 42 is used to raise the height of the spray pipe 41 to prevent it from obstructing the seedling trays. Simultaneously, two sets of drive motors 466 are turned on to rotate the lead screw 465. At this time, the movable rod 461 moves upward along the inside of the guide frame 464, and at the same time pushes the water pipe 42 at the upper end of the movable rod 461 upward, ensuring the convenience of adjusting the height of the spray pipe 41 so as to avoid the seedling trays and improve the stability of the spraying operation.

[0033] Example 2

[0034] The difference between this embodiment and embodiment 1 is that, specifically, the positioning sensing component 3 includes a fixing block 31, which is fixedly connected to one side surface of the water pipe 42. A limit cover 32 is fixedly connected to the upper end of the fixing block 31, and a positioning cylinder 33 is fixedly connected to the bottom end of the limit cover 32. An adjusting column 36 is inserted into the inside of the positioning cylinder 33, and a photoelectric sensor 35 is fixedly connected to the bottom end of the adjusting column 36. A limit spring 37 is connected inside the adjusting column 36, and a positioning insert 34 is fixedly connected to one end of the limit spring 37.

[0035] By adopting the above technical solution, when the seedling tray passes through the interior of the tobacco planter body 1 and moves from the seedling tray conveyor belt 2, the photoelectric sensor 35 senses the seedling tray at the upper end of the seedling tray conveyor belt 2. When the photoelectric sensor 35 is blocked, it indicates that the seedling tray has passed.

[0036] After adjusting the height of the water pipe 42, the position of the photoelectric sensor 35 needs to be readjusted. Pressing the positioning block 34 compresses the limiting spring 37, causing the positioning block 34 to retract into the adjusting column 36. Then, adjust the height of the photoelectric sensor 35 according to its usage requirements, ensuring that the positioning block 34 aligns with the insertion hole inside the positioning cylinder 33. Releasing the positioning block 34 resets the limiting spring 37, pushing the positioning block 34 into the insertion hole inside the positioning cylinder 33. This ensures the ease of adjustment and positioning of the adjusting column 36, guarantees the quality of the photoelectric sensor 35, prevents missed detections, and ensures operational stability.

[0037] Specifically, the positioning cylinder 33 has several insertion holes corresponding to the positioning insert 34 inside.

[0038] By adopting the above technical solution, the quality of position adjustment of the adjusting column 36 is improved, and the applicability of the equipment is guaranteed.

[0039] Specifically, the fixing block 31 has mounting screw holes corresponding to the positioning cylinder 33 inside, and the limiting cover 32 has an anti-slip pad bonded to its surface.

[0040] By adopting the above technical solution, it is convenient to disassemble and repair the positioning cylinder 33, and to prevent damage to the photoelectric sensor 35 from causing poor sensing quality of the equipment.

[0041] In this embodiment, when the seedling tray passes through the interior of the tobacco planter body 1 and moves from the seedling tray conveyor belt 2, the photoelectric sensor 35 senses the seedling tray at the upper end of the seedling tray conveyor belt 2. When the photoelectric sensor 35 is blocked, it indicates that the seedling tray has passed.

[0042] After adjusting the height of the water pipe 42, the position of the photoelectric sensor 35 needs to be readjusted. Pressing the positioning block 34 compresses the limiting spring 37, causing the positioning block 34 to retract into the adjusting column 36. Then, adjust the height of the photoelectric sensor 35 according to its usage requirements, ensuring that the positioning block 34 aligns with the insertion hole inside the positioning cylinder 33. Releasing the positioning block 34 resets the limiting spring 37, pushing the positioning block 34 into the insertion hole inside the positioning cylinder 33. This ensures the ease of adjustment and positioning of the adjusting column 36, guarantees the quality of the photoelectric sensor 35, prevents missed detections, and ensures operational stability.

[0043] The main body 1 of the tobacco planter in this utility model is based on existing publicly available technology, and the selected model is 2BS-6.

[0044] In this utility model, the photoelectric sensor 35 is a previously disclosed technology, and the selected model is OMCH-M18.

[0045] The working principle and usage process of this utility model are as follows: When using this utility model, water needs to be sprayed onto the seedling tray after sowing tobacco so that the coated seeds can be broken down in a timely and even manner. When the seedling tray passes through the body 1 of the tobacco planter and moves from the seedling tray conveyor belt 2, the photoelectric sensor 35 senses the seedling tray at the upper end of the seedling tray conveyor belt 2. When the photoelectric sensor 35 is blocked, it indicates that the seedling tray has passed. At this time, water is supplied to the water pipe 42 through the connecting pipe 45. At the same time, water is sprayed from the bottom end of the spray pipe 41 to humidify the coated seeds in the seedling tray, improve the seed germination rate, and ensure the cultivation quality of tobacco.

[0046] When spraying different seedling trays, the adjustable water pipe 42 is used to raise the height of the spray pipe 41 to prevent it from obstructing the seedling trays. Simultaneously, two sets of drive motors 466 are turned on to drive the lead screw 465 to rotate. At this time, the movable rod 461 moves upward along the inside of the guide frame 464, and at the same time pushes the water pipe 42 at the upper end of the movable rod 461 to move upward, ensuring the convenience of adjusting the height of the spray pipe 41 so as to avoid the seedling trays and improve the stability of the spraying operation.

[0047] After adjusting the height of the water pipe 42, the position of the photoelectric sensor 35 needs to be readjusted. Pressing the positioning block 34 compresses the limiting spring 37, causing the positioning block 34 to retract into the adjusting column 36. Then, adjust the height of the photoelectric sensor 35 according to its usage requirements, ensuring that the positioning block 34 aligns with the insertion hole inside the positioning cylinder 33. Releasing the positioning block 34 resets the limiting spring 37, pushing the positioning block 34 into the insertion hole inside the positioning cylinder 33. This ensures the ease of adjustment and positioning of the adjusting column 36, guarantees the quality of the photoelectric sensor 35, prevents missed detections, and ensures operational stability.
