Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a uniform fertilizer spraying mechanism for equidistant topdressing in tobacco floating seedling cultivation. Background Technology

[0002] Floating tobacco seedling raising involves floating foam trays filled with a lightweight seedling substrate on the water surface. Seeds are sown in the substrate, and seedlings take root and grow within it, absorbing water and nutrients from both the substrate and the waterbed. Topdressing techniques are crucial for ensuring robust seedling growth in floating tobacco seedling raising; typically, the seedbed needs to be fertilized 2-3 times during the process.

[0003] There is a utility model patent with application number 201720995254.0 entitled "A Precision Topdressing Device for Tobacco Floating Seedling Cultivation". It includes a handcart, which includes a tray, a handle and rollers. The handcart is equipped with a fertilizer tank, a motor, a water pump, a battery and a controller. The battery is connected to the motor, and the motor is connected to the water pump through a transmission mechanism. The water pump inlet pipe is connected to the inside of the fertilizer tank, and the water pump outlet pipe is equipped with a flow meter. The flow signal of the flow meter is transmitted to the controller, and the controller controls the motor to start and stop according to the flow signal.

[0004] Because fertilizer needs to be spread evenly to avoid localized high concentrations that could damage the tobacco seedlings, and because the seedling beds are quite long, the fertilizer application process needs to follow a "5-point S-shape" to improve uniformity. However, the above method involves manually applying fertilizer by hand, which cannot guarantee uniformity. It requires the use of a water scoop and stirring, which is not only labor-intensive but also prone to tearing the bed membrane and damaging the roots of the tobacco seedlings during the stirring process. Utility Model Content

[0005] The purpose of this invention is to solve the above problems and provide a uniform fertilizer spraying mechanism for equidistant topdressing in tobacco floating seedling cultivation, which can perform bottom fan-shaped topdressing and increase uniformity.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A uniform fertilization spraying mechanism for equidistant topdressing in floating tobacco seedling cultivation includes a fertilization spraying pipe, a movable frame, a vertical pipe passing through the upper end of the movable frame and rotatably connected to the movable frame, and a horizontal pipe set at the bottom of the vertical pipe. The main pipe of the fertilization spraying pipe extends into the vertical pipe, and the branch pipes of the fertilization spraying pipe extend out through both ends of the horizontal pipe.

[0008] Furthermore, the bottom of the mobile frame is equipped with casters.

[0009] Furthermore, the upper end of the movable frame is provided with a guide sleeve, and the vertical tube passes through the guide sleeve and is movably connected to the guide sleeve.

[0010] Furthermore, a positioning mechanism is provided between the guide sleeve and the vertical tube.

[0011] Furthermore, the positioning mechanism includes a guide groove disposed inside the guide sleeve. The guide groove includes a vertical part with its lower end communicating with the outside, a horizontal part disposed at the upper end of the vertical part, and a positioning groove disposed at the end of the horizontal part. A guide rod that cooperates with the guide groove is provided on the outer cylindrical surface of the vertical tube.

[0012] Furthermore, a box is provided at the lower end of the vertical pipe where it connects to the horizontal pipe, and arc-shaped portions are provided on both sides of the box.

[0013] Furthermore, the horizontal tube is provided with positioning screws for fixing the nozzle.

[0014] Furthermore, a handle is provided at the upper end of the vertical tube.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model includes a movable frame, a vertical pipe passing through the upper end of the movable frame and rotatably connected to the movable frame, and a horizontal pipe set at the bottom of the vertical pipe. The main pipe of the fertilizer spraying pipe extends into the vertical pipe, and the branch pipes of the fertilizer spraying pipe extend out through both ends of the horizontal pipe. When applying fertilizer at equal intervals in tobacco floating seedling cultivation, the movable frame is moved to the fertilizer spraying point, the vertical pipe is lowered, so that the horizontal pipe is lowered into the water pool under the seedling tray. The fertilizer spraying pipe sprays fertilizer in the water pool, and the vertical pipe is rotated synchronously, so that the nozzles at the ends of the branch pipes of the fertilizer spraying pipe move slowly from one side to the other in a fan shape in the water pool, ensuring the uniformity of fertilization and preventing seedling burn due to uneven fertilizer application. At the same time, it also prevents the pool membrane from being torn and the tobacco seedling roots from being damaged by stirring with water scoops. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0025] A uniform fertilizer spraying mechanism for equidistant topdressing in tobacco floating seedling cultivation includes a fertilizer spraying pipe 1, such as... Figure 5 As shown, the fertilizer spraying pipeline 1 includes a main pipeline and branch pipelines. The main pipeline and branch pipelines are connected by a three-way valve. The main pipeline is connected to the fertilizer tank, and a pump is installed on the main pipeline. Figure 1 As shown, the system also includes a movable frame 2, a vertical pipe 3 passing through the upper end of the movable frame 2 and rotatably connected to it, and a horizontal pipe 4 located at the bottom of the vertical pipe 3. The main pipe of the fertilizer spraying pipe 1 extends into the vertical pipe 3, and the branch pipes of the fertilizer spraying pipe 1 extend out through both ends of the horizontal pipe 4. When applying fertilizer at equal intervals during floating tobacco seedling cultivation, the movable frame 2 is moved to the fertilizer spraying point, the vertical pipe 3 is lowered, causing the horizontal pipe 4 to descend into the water tank under the seedling tray. The fertilizer spraying pipe sprays fertilizer in the water tank, and simultaneously the vertical pipe 3 is rotated, causing the nozzles at the ends of the branch pipes of the fertilizer spraying pipe to slowly move in a fan shape from one side to the other in the water tank at an angle of 180 degrees. This completes the fertilization work for the tobacco seedlings at that point. Fertilization is carried out sequentially. This ensures the uniformity of fertilization, preventing seedling burn due to uneven fertilizer application, and also preventing damage to the tank membrane and seedling roots caused by stirring with water scoops.

[0026] It should be noted that the descent height of the vertical pipe 3 needs to be controlled so that the horizontal pipe 4 will not damage the roots of the tobacco seedlings when the vertical pipe 3 is rotated.

[0027] like Figure 1 As shown, the movable frame 2 is a portal frame, and the bottom of the movable frame 2 is equipped with casters 5.

[0028] like Figure 1 and Figure 2As shown, the upper end of the movable frame 2 is provided with a guide sleeve 6, and the vertical tube 3 passes through the guide sleeve 6 and is movably connected to the guide sleeve 6. The vertical tube 3 can slide up and down within the guide sleeve 6, and can also rotate within the guide sleeve 6.

[0029] A positioning mechanism is provided between the guide sleeve 6 and the vertical tube 3.

[0030] like Figure 2 , Figure 3 and Figure 4 As shown, the positioning mechanism includes a guide groove 7 disposed inside the guide sleeve 6. The guide groove 7 includes a vertical part 71 with its lower end communicating with the outside, a horizontal part 72 disposed at the upper end of the vertical part 71, and a positioning groove 73 disposed at the end of the horizontal part 72. A guide rod 8 that cooperates with the guide groove 7 is provided on the outer cylindrical surface of the vertical tube 3. When it is necessary to move the position of the moving frame 2 to the next point for fertilization, the vertical tube 3 is lifted, so that the guide rod 8 on the vertical tube 3 cooperates with the guide groove 7 and moves upward along the vertical part 71 of the guide groove 7 until it moves to the top of the vertical part 71. Then, the vertical tube 3 is rotated so that the guide rod 8 moves along the horizontal part 72 until it is positioned in the positioning groove 73, thereby realizing the lifting and fixing of the vertical tube 3, and the vertical tube 3 will not fall when the moving frame 2 moves. After reaching the fertilization point, first lift the vertical pipe 3, separate the guide rod 8 from the positioning groove 73, and rotate the vertical pipe 3 along the horizontal part 72 of the guide groove 7 until the guide rod 8 reaches the vertical part 71. Then, move the vertical pipe 3 down and insert the horizontal pipe at the lower end of the vertical pipe 3 into the water tank under the seedling tray for fertilization.

[0031] like Figure 5 As shown, a box 9 is provided at the lower end of the vertical pipe 3 where it connects to the horizontal pipe 4. Arc-shaped parts 10 are provided on both sides of the box. When the fertilizer spraying pipe passes through the part where the vertical pipe 3 connects to the horizontal pipe 4, the bending angle of the fertilizer spraying pipe is reduced, wear is prevented, service life is increased, and the fertilizer spraying pipe is also easy to disassemble and assemble.

[0032] like Figure 4 As shown, the horizontal tube 4 is provided with positioning screws 11 for fixing the nozzle.

[0033] like Figure 1 As shown, the upper end of the vertical pipe 3 is equipped with a handle 12, which facilitates raising and lowering the vertical pipe 3 and also allows for rotation of the vertical pipe 3 during fertilization. When the vertical pipe 3 is lowered to its lowest point for fertilization, the handle 12 can be supported by the guide sleeve 6, thereby achieving the positioning of the height of the vertical pipe 3. Alternatively, the handle can be manually rotated by hand. Those skilled in the art can also choose to provide a baffle on the vertical pipe 3, with the baffle contacting the guide sleeve 6, to position the height of the vertical pipe 3. This is an obvious approach and will not be elaborated upon further here.
