Description

Technical Field

[0001] This utility model relates to the field of rapeseed processing technology, specifically to a drying and screening device for rapeseed. Background Technology

[0002] Rapeseed, also known as rapeseed, belongs to the Brassicaceae family and is not only an important oilseed crop in China but also a significant source of nectar for bees. Its seeds are a key raw material for extracting high-quality oil and are widely used in various fields. Before oil extraction, rapeseed typically undergoes drying and screening processes to reduce its moisture content and remove impurities such as stones.

[0003] As mentioned in the published Chinese patent CN222174768U, a rapeseed screening and drying integrated machine includes: "An operating table covered with a dust suppression cover, three support plates fixed on the upper surface of the operating table, a drying and screening component mounted on the support plates, and a drive component mounted on the drying and screening component; this utility model, by adding a drying and screening component, allows rapeseed to be placed into a screening mesh tank during use, and then the screening mesh tank is threaded onto a second bevel gear. The drive motor rotates, causing the rotating rod to drive the screening mesh tank to screen the rapeseed, leaving plump and high-quality rapeseed. Simultaneously, a hot air blower delivers hot airflow into the rotating rod, and the support rod disperses the hot airflow into the screening mesh tank. This allows the device to dry the rapeseed simultaneously with the hot airflow, simplifying the rapeseed processing and improving the efficiency of rapeseed screening and drying."

[0004] Through a search of the aforementioned patents, we found that this technology still has certain drawbacks in its use. Because the screening tank is threaded onto the second bevel gear, both the drying and screening of rapeseed take place within the screening tank. Therefore, the screening tank needs to be disassembled and reassembled when placing and removing the rapeseed after processing, which causes operational inconvenience and poor smoothness in the drying and screening process, resulting in low efficiency. Therefore, to address the aforementioned technical problems in the existing technology, we have specifically designed a rapeseed drying and screening device. Utility Model Content

[0017] 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.

[0018] Please see Figure 1-5A drying and screening device for rapeseed includes a housing 1. A heat dissipation mesh 101 is installed on the back of the housing 1 to facilitate the dissipation of heat from inside the housing 1. A drying cylinder 8 is installed inside the housing 1, and an electric heating plate 9 is installed on the outer wall of the drying cylinder 8. The electric heating plate 9 is connected to mains power via wires. When the electric heating plate 9 is activated, it heats the drying cylinder 8, thereby heating the rapeseed inside. A feed hopper 4 is connected to the top of the drying cylinder 8. A stirring rod 10 is rotatably connected to the inner bottom wall of the drying cylinder 8. The bottom of the stirring rod 10 extends through to the bottom of the drying cylinder 8 and is connected to a driven bevel gear 11. A servo motor is installed on the right side of the housing 1. The power output shaft of the servo motor 3 extends through the interior of the housing 1 and is connected to a rotating rod 301. The rotating rod 301 is equipped with a driving bevel gear 302 that meshes with the driven bevel gear 11. After the servo motor 3 starts, it can use its power output shaft to drive the driving bevel gear 302 to rotate, thereby driving the driven bevel gear 11 that meshes with it to rotate, and finally driving the rotating rod 301 to rotate. Inside the housing 1 and located on one side of the bottom of the drying cylinder 8, a screening assembly is also provided. The screening assembly includes a screening frame 13 and a receiving frame 14. On the right side of the housing 1, there is also a discharge frame 5 that communicates with the screening frame 13 and a discharge frame 6 that communicates with the receiving frame 14.

[0019] Please see Figure 2 , Figure 4 as well as Figure 5 In this embodiment, both the screening frame 13 and the receiving frame 14 are designed as inclined structures. The screening frame 13 is fixed to the top of the receiving frame 14 by four springs 16, and the bottom of the receiving frame 14 is fixed to the inner bottom wall of the box 1 by a support frame. The inner bottom wall of the screening frame 13 is evenly provided with drainage holes, and the inner bottom wall of the receiving frame 14 is a smooth surface. One side of the screening frame 13 extends into the discharge frame 5, and one side of the receiving frame 14 extends into the discharge frame 6.

[0020] Specifically, the inclined screening frame 13 and receiving frame 14 facilitate the sliding of rapeseed and impurities, allowing them to enter the discharge frame 5 and discharge frame 6 respectively. The spring 16 of the screening frame 13 is fixed to the top of the receiving frame 14, providing support for the screening frame 13 and allowing it to vibrate, thus facilitating the falling of impurities through the holes on the bottom wall of the screening frame 13 into the receiving frame 14. Please see Figure 1 , Figure 2 as well as Figure 5 In this embodiment, a servo motor 2 is also installed on the front of the housing 1. The power output shaft of the servo motor 2 extends through the interior of the housing 1 and is connected to an eccentric wheel 201. The eccentric wheel 201 is located between the screening frame 13 and the receiving frame 14.

[0021] Specifically, by starting the servo motor 2, its power output shaft can drive the eccentric wheel 201 to rotate, thereby facilitating the application of shaking force to the screening frame 13, which in turn facilitates the screening of impurities in the rapeseed when the screening frame 13 shakes.

[0022] Please see Figure 1 , Figure 2 as well as Figure 5 In this embodiment, the top of the drying cylinder 8 is fixed to the inner top wall of the box body 1. The inner bottom wall of the drying cylinder 8 is designed as an inclined structure. The bottom of the drying cylinder 8 near the screening frame 13 is connected to the discharge port 12. The discharge port 12 is located above the screening frame 13 and is also designed as an inclined structure. A pull rod 7 is also provided on the front of the box body 1 at the position corresponding to the discharge port 12. One end of the pull rod 7 moves through the interior of the box body 1 and is fixed with a sealing cover 701. One side of the sealing cover 701 is inserted into the discharge port 12. A fixing frame 15 for supporting the pull rod 7 is also fixed on the inner wall of the box body 1. The pull rod 7 moves through the fixing frame 15.

[0023] Specifically, the inner bottom wall of the drying cylinder 8 is designed with an inclined structure, which allows the rapeseed to slide easily from the inclined surface and be discharged from the outlet 12. The outlet 12 has a sealing cover 701, which can block the outlet 12 during the drying operation to prevent the rapeseed from leaking out. When discharge is needed later, simply pull the lever 7. The lever 7 is stabilized by the support of the fixing frame 15, which makes it easy for the sealing cover 701 to be stably removed from or inserted into the outlet 12.

[0024] Please see Figure 2 In this embodiment, stirring blades are equidistantly arranged on the rod body of the stirring rod 10, and a gap is left between the side of the stirring blades away from the stirring rod 10 and the inner wall of the drying cylinder 8.

[0025] Specifically, when the stirring rod 10 rotates, it can simultaneously drive the stirring blade connected to it to rotate, thereby stirring the camellia seeds inside the drying cylinder 8, achieving a turning effect, and making the heating more uniform. The stirring blade is far away from the inner wall of the drying cylinder 8, which can prevent the stirring blade from squeezing and damaging the rapeseed when rotating.

[0026] In use: The rapeseed that needs to be dried and screened is fed from the feed hopper 4 into the drying cylinder 8, and the electric heating plate 9 is activated to heat the rapeseed inside the drying cylinder 8. Then, the servo motor 2 3 is activated. The power output shaft of the servo motor 2 3 drives the rotating rod 301 to rotate, which in turn drives the active bevel gear 302 to rotate, which in turn drives the driven bevel gear 11 to rotate, and finally drives the stirring rod 10 to rotate. The stirring blades on the stirring rod 10 are used to stir the rapeseed inside the drying cylinder 8, making it move and simulating the effect of stir-frying, thus improving the drying effect of the rapeseed. After the rapeseed drying is completed, the staff can start the servo motor 2, which drives the eccentric wheel 201 to rotate, which shakes the screening frame 13. Then, the pull rod 7 is pulled to remove the sealing cover 701 from the discharge port 12, so that the rapeseed inside the drying cylinder 8 can be directly discharged into the screening frame 13. As the screening frame 13 shakes, the rapeseed on the screening frame 13 can be screened, so that impurities such as stones in the rapeseed are screened out and fall into the receiving frame 14. Finally, the rapeseed on the screening frame 13 is discharged from the discharge frame 5, and the impurities on the receiving frame 14 are discharged from the discharge frame 6.

[0027] It should be noted that since the box body 1 has two drying cylinders 8 inside, each with a feed hopper 4 at the top, an electric heating plate 9 on the surface, a driven bevel gear 11 and a driving bevel gear 302 at the bottom, and a discharge port 12 and a sealing cover 701 on one side, the two drying cylinders 8 can work simultaneously, increasing the amount of rapeseed dried and screened each time, thereby improving efficiency. Alternatively, the two drying cylinders 8 can work intermittently, with one drying cylinder 8 drying while the other discharges and refills the cylinder with rapeseed. The intermittent operation does not affect each other, thus saving time. This avoids the situation where only one drying cylinder 8 requires discharging the dried rapeseed before refilling it with rapeseed. The choice of which method to use depends on the actual situation.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
