Description

Technical Field

[0001] This utility model relates to a tobacco seed pelleting machine. Background Technology

[0002] Seed pelleting technology is a technique that uses specific powders and solutions to process seeds into small spheres of uniform size and regular shape. Tobacco, as one of my country's important economic crops, has seeds that are light in weight (approximately 0.02~0.025 mg) and tiny in size (approximately 3.081 x 10⁻⁶). -12 x3.85x10 -12 Tobacco seeds, when grown naked (in cubic meters), often exhibit lower resistance to adverse conditions and are susceptible to pests and diseases. Seed pelleting technology not only effectively increases the volume of tobacco seeds but also provides them with essential nutrients and fungicides, resulting in stronger seedlings, disease prevention, and improved resistance to adverse conditions. Using pelleted seeds for seedling cultivation saves on seed usage, facilitates sowing, ensures uniform germination, and conserves labor, thereby improving the overall production quality and economic benefits of tobacco. Traditional seed pelleting is generally done manually, which is time-consuming, labor-intensive, and inefficient. It also suffers from high dependence on operator experience and inconsistent quality. Utility Model Content

[0003] This invention addresses the aforementioned problems by providing a tobacco seed pelleting machine that is convenient and efficient to use.

[0004] The present invention is constructed as follows: it includes a frame and a coating pan body that is mounted on the frame and is rotatable. Above the coating pan body is a powder feeding mechanism for feeding powder into the coating pan body and an annular atomizing mechanism for spraying liquid into the coating pan body. The annular atomizing mechanism includes an annular body, and multiple annular atomizing nozzles are provided below the annular body.

[0005] Furthermore, the coating pan body includes a cylindrical body and a turntable disposed at the bottom of the cylindrical body, and the inner wall of the cylindrical body is provided with a plurality of stirring blades.

[0006] Furthermore, a drive component for driving the turntable to rotate is provided below the turntable.

[0007] Furthermore, the drive assembly includes a motor, a worm gear reducer, and a rotating shaft. The motor is connected to the worm gear reducer, the worm gear reducer is connected to the rotating shaft, and the rotating shaft passes through the platform of the frame and is connected to the turntable.

[0008] Furthermore, a bottom plate is provided below the cylinder, and an avoidance groove is provided in the middle of the bottom plate, with the turntable positioned above the bottom plate.

[0009] Furthermore, the upper and lower ends of the cylinder are open, and flanges are provided on the outer sides of the openings at the upper and lower ends of the cylinder.

[0010] Furthermore, an adhesive tank and a nutrient solution tank are provided on the outside of the annular body. The annular body is connected to the adhesive tank and the nutrient solution tank via pipelines, and each pipeline is equipped with a valve and a pressurizing device.

[0011] Furthermore, the powder feeding mechanism includes a vacuum feeder and a material cylinder arranged sequentially from top to bottom. The input end of the material cylinder is connected to the vacuum feeder, and the output end of the material cylinder is provided with a discharge pipe that extends to the top of the coating pan.

[0012] Furthermore, a screw conveyor is installed inside the discharge pipe.

[0013] Furthermore, a support plate frame is provided below the material cylinder, and a pressure sensor is installed below the support plate frame.

[0014] Compared with the prior art, this utility model has the following beneficial effects: This utility model has a simple structure, reasonable design, and is easy to use. The seed pelleting process is stable and efficient. During the coating operation, a certain mass of tobacco seeds is accurately weighed and placed into the coating pan. Then, the driving component of the coating pan is turned on, and the motor of the driving component rotates the turntable inside the coating pan. At this time, the seeds rapidly migrate towards the edge of the turntable under the strong centrifugal force and form a stable circulation pattern along the inner wall of the coating pan. Simultaneously, the powder feeding mechanism is activated. Precisely metered powder falls uniformly from the feeding pipe through the feeding cylinder and auger feeding device, fully interacting with the seeds on the high-speed rotating turntable. The process involves uniform mixing, simultaneously activated by the ring-shaped atomizing mechanism. The ring-shaped atomizing nozzles spray the solution evenly in a mist form, ensuring comprehensive and deep mixing of the solution with the seeds and powder within the coating pan. Throughout the coating process, the solution is supplied continuously at a low flow rate to maintain appropriate moisture on the seed and powder surfaces, while the powder is precisely replenished in predetermined batches. As the seeds continuously move within the coating pan, they adhere to the sprayed solution and falling powder, gradually coating the seed surface and ultimately forming pellets. This completes the pelleting coating process for tobacco seeds, significantly improving work efficiency and quality. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] Example 1: As Figure 1-8 As shown in the present invention, a tobacco seed pelleting machine is provided, including a frame 1 and a coating pan 2 mounted on the frame and rotatable. Above the coating pan is a powder feeding mechanism 3 for feeding powder into the coating pan and an annular atomizing mechanism 4 for spraying liquid into the coating pan. The annular atomizing mechanism includes an annular body 401, and multiple annular atomizing nozzles 402 are provided below the annular body. The interior of the annular body is a cavity, which is connected to the annular atomizing nozzles, an adhesive tank, and a nutrient solution tank via pipelines.

[0025] The inner ring of the aforementioned annular body is also provided with a Y-shaped pipe 403, and the inner cavity of the Y-shaped pipe is also connected to the cavity of the annular body.

[0026] During operation: First, a certain amount of tobacco seeds is accurately weighed and placed into the coating pan. Then, the drive unit of the coating pan is turned on, and the motor of the drive unit drives the turntable inside the coating pan to rotate. At this time, the seeds quickly migrate to the edge of the turntable under the action of strong centrifugal force and form a stable circulation pattern along the inner wall of the coating pan. At the same time, the powder feeding mechanism is started. The powder, after being precisely metered, falls at a constant speed from the feeding pipe through the feeding cylinder and auger feeding device. It is fully and evenly mixed with the seeds on the high-speed rotating turntable. Simultaneously, the annular atomizing mechanism is turned on. The annular atomizing nozzle of the annular atomizing mechanism sprays the solution evenly in an atomized form, ensuring that the solution, seeds and powder are fully and deeply mixed in the coating pan.

[0027] It is worth noting that during the entire coating process, the solution is supplied continuously at a low flow rate to maintain appropriate moisture on the surface of the seeds and materials, while the powder is replenished precisely in predetermined batches. As the seeds move continuously in the coating pan, they constantly adhere to the sprayed solution and the falling powder, causing the outer surface of the seeds to be gradually coated, eventually forming pellets and completing the pelleting coating process of tobacco seeds.

[0028] In this embodiment of the present invention, the coating pot body 2 includes a cylindrical body 201 and a turntable 202 disposed at the bottom of the cylindrical body, and a plurality of stirring blades 203 are disposed on the inner wall of the cylindrical body.

[0029] In this embodiment of the invention, a drive component for driving the turntable to rotate is provided below the turntable.

[0030] In this embodiment of the utility model, the drive assembly includes a motor 204, a worm gear reducer 205, and a rotating shaft 206. The motor is connected to the worm gear reducer, the worm gear reducer is connected to the rotating shaft, and the rotating shaft passes through the table surface of the frame and is connected to the turntable.

[0031] A bearing 207 is installed between the table surface of the frame and the turntable.

[0032] In this embodiment of the utility model, a bottom plate 208 is provided below the cylinder, and an avoidance groove is provided in the middle of the bottom plate. The turntable is located above the bottom plate.

[0033] In this embodiment of the utility model, the upper and lower ends of the cylinder are open, and flanges 209 are provided on the outer side of the openings at the upper and lower ends of the cylinder.

[0034] In this embodiment of the utility model, an adhesive tank and a nutrient solution tank are provided on the outside of the annular body. The annular body is connected to the adhesive tank and the nutrient solution tank via pipelines. Each pipeline is equipped with a valve and a pressurizing device; the pressurizing device can be a liquid pump.

[0035] During normal operation, the valves of the nutrient solution pipeline are closed, while the valves of the adhesive pipeline are open. The adhesive enters the annular body through the pipeline and is evenly sprayed through the annular atomizing nozzle to achieve adsorption between tobacco seeds and powder. In the middle stage of coating, the valves of the nutrient solution pipeline are open, while the valves of the adhesive pipeline are closed. The nutrient solution is evenly sprayed through the annular atomizing nozzle to provide nutrients for seed coating.

[0036] Of course, if necessary, the valves on the adhesive and nutrient solution pipelines can be opened simultaneously.

[0037] In this embodiment of the utility model, the powder feeding mechanism 3 includes a vacuum feeder 301 and a material cylinder 302 arranged sequentially from top to bottom. The vacuum feeder is the prior art. The input end of the material cylinder is connected to the vacuum feeder. The output end of the material cylinder is provided with a discharge pipe 303. The discharge pipe extends to the top of the coating pan body. The discharge pipe can be in the shape of a bend or an L-shape.

[0038] The aforementioned discharge pipe includes a straight pipe 304 and a bent pipe 305. The upper left side of the straight pipe has a feed inlet 306, which is directly below the output end of the material cylinder. The left side of the bent pipe is connected to the straight pipe, and the right side of the bent pipe extends into the material cylinder. The auger feeding device is installed inside the straight pipe.

[0039] In this embodiment of the utility model, an auger feeding device 307 is provided inside the discharge pipe; the auger feeding device includes an auger shaft disposed inside the straight pipe of the discharge pipe and auger spiral blades disposed on the auger device, and the auger shaft is driven to rotate by an auger motor; the auger feeding device is prior art and will not be described in detail here.

[0040] Example 2: Based on Example 1, in this embodiment of the present invention, a support plate frame 308 is provided below the material cylinder, and a pressure sensor 309 is provided below the support plate frame; three pressure sensors may be provided, and the pressure sensors here may be weighing sensors.

[0041] The pressure sensor can monitor and calculate the weight of the powder in the barrel in real time, ensuring precise control during the production process, and discharge the powder into the coating pan through the discharge pipe.

[0042] The material cylinder is installed on the support plate frame, and the lower part of the material cylinder passes through the support plate frame to form the output end of the material cylinder, which is directly opposite the input port of the auger feeding device.

[0043] In this embodiment of the utility model, the vacuum feeder is a dust-free, closed pipeline conveying device that uses vacuum suction to convey granular and powdery materials. It utilizes the pressure difference between the vacuum and the ambient space to create gas flow within the pipeline, which in turn drives the powdery materials to move, thereby completing the conveying of the powder.

[0044] The vacuum feeder 301 includes a vacuum feeder body 3011, a pneumatic valve 3012, a pneumatic control box 3013, an air filter 3014, a vacuum feeder inlet 3015, a vacuum feeder outlet 3016, and a vacuum generator 3017, etc. The vacuum feeder outlet is connected to the input end of the material cylinder, and the vacuum feeder inlet is connected to an external powder source.

[0045] When the vacuum feeder is working, when compressed air is supplied to the vacuum generator, the vacuum generator generates negative pressure to form a vacuum airflow. The powder enters the material cylinder through the feed port of the vacuum feeder. The air filter completely separates the powder from the air. When the material cylinder is full, the pneumatic control box will automatically cut off the air supply, the vacuum generator will stop working, and the hopper door will open automatically, and the material will be output from the discharge port of the vacuum feeder.
