Description

Technical Field

[0001] This utility model relates to the field of tobacco anther threshing technology, specifically a tobacco anther threshing machine. Background Technology

[0002] In recent years, the drawbacks of the traditional tobacco seed production model have gradually become apparent, with the structural shortage of labor resources being particularly prominent. This is manifested in an unstable workforce, an aging workforce, and a high turnover rate of skilled workers. Low levels of mechanization in the production process lead to excessive labor intensity and low work efficiency, negatively impacting the overall efficiency of seed production. Looking at the entire tobacco seed production process, while land preparation, irrigation, fertilization, and plant protection have achieved initial mechanization or facility-based systems based on successful experience in tobacco leaf production, the unique aspects of seed production, which also account for the largest share of labor demand, such as field pollination, pollen collection, anther threshing, capsule harvesting, and seed screening and grading, remain primarily traditional manual operations, severely hindering the technological upgrading of the tobacco seed production industry.

[0003] To further improve the mechanization level of tobacco seed production, reduce the labor intensity of workers, increase production efficiency, and solve the key core technologies that restrict tobacco seed production, the plan is to start from important links such as field pollination and anther collection, and develop special mechanized equipment suitable for tobacco seed production by leveraging modern agricultural machinery design concepts and manufacturing technologies. Utility Model Content

[0004] The purpose of this invention is to provide a tobacco anther threshing machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tobacco anther threshing machine, comprising:

[0006] Rack 1;

[0007] A synchronous belt conveyor is installed in the middle of the frame. A pressing conveyor is provided above the synchronous belt conveyor. The pressing conveyor includes a pressing synchronous belt with its bottom parallel to the synchronous belt conveyor and a drive motor for driving the pressing synchronous belt to rotate.

[0008] A threshing mechanism is located on one side of the synchronous belt conveyor. The threshing mechanism includes a rotating main shaft, and multiple connecting plates are fixedly connected at equal intervals to the outer side of the main shaft. Multiple threshing steel needles are inclinedly arranged at the end of each connecting plate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , 2 As shown in Figures 3, 4, and 5, this utility model provides a technical solution: a tobacco anther threshing machine, comprising: a frame 1; a synchronous belt conveyor 2 installed in the middle of the frame 1, the synchronous belt conveyor 2 including a support frame, synchronous pulleys rotatably installed at both ends of the support frame, a synchronous conveyor belt installed on the outside of the two synchronous pulleys, and a motor driving the synchronous pulleys to rotate; a pressing conveying section is provided above the synchronous belt conveyor 2, the pressing conveying section including a pressing synchronous belt 5 arranged parallel to the bottom of the synchronous belt conveyor 2, and a drive motor 6 driving the pressing synchronous belt 5 to rotate; a threshing mechanism is located on one side of the synchronous belt conveyor 2, the threshing mechanism including a main shaft 7 rotatably arranged in the middle of the frame 1, multiple connecting plates 15 are equidistantly installed on the outside of the main shaft 7 by bolts, and multiple threshing steel needles 8 are inclinedly arranged at the end of each connecting plate 15; a screening section is located below the synchronous belt conveyor 2 for screening and separating anthers.

[0024] It should be noted that this utility model is equipped with a corresponding operation panel and frequency converter. During operation, the operator is responsible for feeding the tobacco flowers and placing them on top of the synchronous belt conveyor 2. Under the squeezing and conveying action of the synchronous belt conveyor 2 and the pressing synchronous belt 5, the tobacco flowers are slowly conveyed forward. During this period, the main shaft 7 drives the threshing steel needle 8 to rotate through the connecting plate 15. The threshing steel needle 8 contacts the tobacco flowers and combs off the petals of the tobacco flowers. At the same time, it combs off the anthers in the fireworks. After the combed-off anthers enter the screening section, they fall into the vibrating sieve provided by the vibrating motor. The anthers and petals are separated after sorting.

[0025] Please see Figure 1 , 2As shown in Figures 3 and 5, the pressing and conveying unit also includes a vertical plate 3 fixed to one side of the top of the frame 1. A drive motor 6 is fixed to one side of the vertical plate 3, and a drive synchronous pulley 14 is fixedly connected to the output end of the drive motor 6. Two driven synchronous pulleys 4 are rotatably connected to one side of the vertical plate 3. The drive synchronous pulley 14 and the two driven synchronous pulleys 4 are arranged in an isosceles triangle structure. The two drive synchronous pulleys 14 and the driven synchronous pulleys 4 are connected by a pressing synchronous belt 5. The two driven synchronous pulleys are rotatably mounted on one side of the vertical plate 3 and are responsible for driving the movement of the pressing synchronous belt. The pressing synchronous belt 5 connects the drive synchronous pulley 14 and the driven synchronous pulleys 4. Under the transmission action, the pressing synchronous belt and the synchronous belt conveyor 2 convey the tobacco flowers to achieve pressing and conveying. The drive motor 6 is located on one side of the vertical plate 3 and drives the drive synchronous pulley 14 to rotate through the rotation of the motor. The rotation of the drive synchronous pulley 14 drives the two driven synchronous pulleys 4 to rotate. The driving synchronous pulley 14 and the two driven synchronous pulleys 4 are connected by a pressing synchronous belt 5, which works together to make the pressing synchronous belt 5 run along the transmission system. When the tobacco flowers are conveyed by the synchronous belt conveyor 2 to the area between the synchronous belt conveyor 2 and the pressing synchronous belt 5, the pressing synchronous belt, under the combined action of their heights, ensures that the tobacco flowers are stably and evenly transferred during the conveying process by squeezing and conveying them, avoiding material slippage or uneven conveying. The operation of the pressing synchronous belt 5 ensures that the tobacco flowers receive appropriate pressure and conveying between the synchronous belt conveyor and the pressing synchronous belt, thereby improving the threshing effect of the anthers and ensuring that the anthers are more easily separated from the petals.

[0026] Please see Figure 1 , 5 As shown, the spindle 7 is rotatably mounted in the middle of the frame 1, and the drive motor 9 for driving the spindle 7 is mounted on one side of the frame 1 via a motor bracket and bolts.

[0027] It should be noted that the drive motor 29 of this utility model drives the connecting plate 15 to rotate through the main shaft 7. The connecting plate 15 drives the threshing steel needle 8 to rotate clockwise. During the process of the tobacco flowers being slowly conveyed at the top of the synchronous belt conveyor 2, the threshing steel needle 8 repeatedly combs the tobacco flowers, combing off the petals and anthers from the tobacco flowers.

[0028] Please see Figure 1 , 2 As shown in Figures 3 and 4, the screening section includes a second frame 10 fixed below the first frame 1. A hopper 12 is fixed to the top of the second frame 10 by a spring 11. The hopper 12 is inclined and its end is located below the synchronous belt conveyor 2. Vibration motors 13 are fixed to both sides of the hopper 12, and a screen 16 is fixedly connected to the middle of the hopper 12.

[0029] It should be noted that, in this invention, after the tobacco flowers are combed and threshed by the threshing steel needles 8, they fall onto the screen 16 guided within the hopper 12. The vibrating motor 13 drives the hopper to vibrate, and the material moves along the vibration direction on the screen. The anthers are sieved through the mesh of the screen, while the petals, being larger, are intercepted by the screen and discharged through the two outlets at the ends of the hopper 12, which face different directions.
