Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, specifically a device for rapid coating and drying of rapeseed seeds. Background Technology

[0002] With the continuous advancement of agricultural modernization, the requirements for seed treatment in the rapeseed planting industry are increasing. Seed coating and drying are crucial steps before rapeseed planting. Good coating can enhance the seeds' resistance to diseases and pests and improve the germination rate, while effective drying can ensure the storage quality of the seeds and the subsequent sowing effect.

[0003] In existing technologies, traditional rapeseed coating equipment often suffers from uneven coating. Due to improper stirring methods or limited stirring range, the coating material cannot fully contact the seeds, resulting in some seeds being over-coated while others are under-coated or even uncoated. This seriously affects seed quality and subsequent growth. In the dehydration and drying stage, most existing dehydration devices rely solely on centrifugal dehydration, which has low efficiency and leaves a lot of residual moisture in the seeds. This not only prolongs the subsequent drying time and increases energy consumption, but also easily leads to uneven drying due to the uneven moisture content of the seeds. Furthermore, existing coating and dehydration / drying equipment are usually two separate devices, and the process of transferring seeds between different devices is cumbersome. Therefore, we propose a rapid rapeseed coating and drying device to solve the above problems. Utility Model Content

A rotating tube is fixedly connected to the inner wall of the upper cover plate. The upper end of the rotating rod passes through the inner wall of the rotating tube and extends to the top of the upper cover plate. A magnetic ring is sleeved on the surface of the rotating rod. The rotating tube and the magnetic ring are connected by a reciprocating thread. A set of blades is fixedly connected to the surface of the magnetic ring. A strip groove is formed on the surface of the magnetic ring. An L-shaped plate is slidably connected to the inner wall of the strip groove.

[0007] Preferably, the dehydration device further includes an annular frame, which is fixed at both ends of the draining bucket. A heating coil is sleeved on the surface of the annular frame.

[0008] Preferably, the driving device further includes a driving wheel, which is fixed to the right end of the driving shaft.

[0011] This utility model provides an improved device for rapid coating and drying of rapeseed seeds, which has the following improvements and advantages compared with the prior art:

[0012] Firstly, this utility model achieves efficient coating operations through a unique structural design in the coating device. The rotating rod and rotating tube are connected to the magnetic ring via a reciprocating thread transmission. When the drive device drives the two to rotate, the magnetic ring moves up and down along the rotating rod, and the blades on its surface stir the seeds in all directions, allowing the coating material to fully contact the seeds. This design greatly improves the uniformity and quality of coating.

[0013] Secondly, this invention achieves a preheating function in the dehydration stage through the principle of electromagnetic induction. When the magnetic ring in the coating device moves up and down to cut the magnetic field lines around the coil, it generates an induced current. This current is transmitted to the heating coil in the dehydration device, causing the heating coil to heat up. While the seeds are centrifuged and dehydrated, the heating coil preheats the seeds, accelerating the evaporation of moisture in the seeds and improving the dehydration efficiency. Moreover, when the preheated seeds enter the drying chamber for final drying, the drying time is shortened and energy consumption is reduced because the seeds have already lost some moisture in advance.

[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] This utility model provides an improved device for rapid coating and drying of rapeseed seeds. The technical solution of this utility model is as follows:

[0024] like Figure 1 - Figure 5 As shown, a device for rapid coating and drying of rapeseed includes a base plate 1, a side plate 2 fixedly connected to the upper surface of the base plate 1, an annular plate 4 fixedly connected to the side wall of the side plate 2, a support plate 5 fixedly connected to the upper surface of the annular plate 4, a coating device, a dehydration device and a driving device arranged above the base plate 1, the coating device including a conical cylinder 6, the conical cylinder 6 being arranged above the annular plate 4, the upper end of the conical cylinder 6 being fixedly connected to an upper cover plate 7, the side wall of the upper cover plate 7 being hinged to an opening and closing plate 8, the dehydration device including a connecting cylinder 18, the connecting cylinder 18 being fixed to the inner wall of the annular plate 4, the right end of the connecting cylinder 18 being rotatably connected to a drain bucket 19, and the driving device including a motor 27, the motor 27 being fixed to the upper surface of the support plate 5, the output end of the motor 27 being fixedly connected to a drive shaft 28.

[0025] Furthermore, the coating device also includes a coil 9, which is sleeved on the surface of the conical cylinder 6. A fixed support plate 10 is rotatably connected to the lower end of the conical cylinder 6. A rotating rod 11 is installed inside the conical cylinder 6. A rotating tube 12 is fixedly connected to the inner wall of the upper cover plate 7. The upper end of the rotating rod 11 passes through the inner wall of the rotating tube 12 and extends to the top of the upper cover plate 7. A magnetic ring 35 is sleeved on the surface of the rotating rod 11. The rotating tube 12 and the magnetic ring 35 are connected by a reciprocating thread. A set of blades 13 is fixedly connected to the surface of the magnetic ring 35. A strip groove 14 is opened on the surface of the magnetic ring 35. An L-shaped plate 15 is slidably connected to the inner wall of the strip groove 14. A strip plate 16 is fixedly connected to the side wall of the L-shaped plate 15. The strip plate 16 is fixedly connected to the inner wall of the conical cylinder 6. A switch valve 17 is rotatably connected to the lower end of the fixed support plate 10. The switch valve 17 is rotatably connected to the upper end of the connecting cylinder 18. Due to the limiting effect of the strip groove 14 and the L-shaped plate 15, the magnetic ring 13 is rotatably connected to the inner wall of the conical cylinder 6. The magnetic ring 35 does not rotate with the rotating rod 11, but moves with the strip plate 16. Since the strip plate 16 is fixedly connected to the conical cylinder 6, the magnetic ring 35 rotates in the same direction as the conical cylinder 6, but in the opposite direction to the rotating rod 11. Therefore, the magnetic ring 35 reciprocates on the rotating rod 11. The coil 9 is sleeved on the surface of the conical cylinder 6 and cooperates with the magnetic ring 35 to generate electromagnetic induction. When the magnetic ring 35 moves up and down along the rotating rod 11, it cuts the magnetic field lines around the coil 9 and generates an induced current to power the heating coil 21 of the dehydration device, realizing the preheating of the dehydration stage. The rotating rod 11 and the rotating tube 12 are connected to the magnetic ring 35 through a reciprocating thread drive. When the drive device drives the two to rotate, the magnetic ring 35 moves up and down along the rotating rod 11. This design allows the blades 13 on the surface of the magnetic ring 35 to stir the seeds in all directions during the up and down movement, ensuring that the coating material is in full contact with the seeds, avoiding uneven local coating, and improving the uniformity and quality of coating.

[0026] Furthermore, the dehydration device also includes a ring frame 20, which is fixed to both ends of the draining bucket 19. A heating coil 21 is fitted on the surface of the ring frame 20. The output end of the coil 9 is electrically connected to the input end of the heating coil 21. A fixed circular plate 22 is rotatably connected to the right end of the draining bucket 19. A switch valve 23 is rotatably connected to the right end of the fixed circular plate 22. A slide rail 24 is fixedly connected to the right end of the fixed circular plate 22, which is fixed to both ends of the draining bucket 19 to provide stable support for the heating coil 21. The slide rail 24 is fixed to the right end of the fixed circular plate 22 to provide a guide channel for the dehydrated seeds, so that the seeds can slide smoothly into the drying box 25 along a predetermined path.

[0027] Furthermore, the drive device also includes a drive wheel 29, which is fixed to the right end of the drive shaft 28. The drive wheel 29 is meshed with an upper driven wheel 30 and a lower driven wheel 31. The upper driven wheel 30 is fixedly connected to the upper end of the rotating rod 11, and the lower driven wheel 31 is fixedly connected to the upper end of the rotating tube 12. The lower end of the rotating rod 11 passes through the inner wall of the fixed support plate 10 and the switch valve 17 and extends into the interior of the connecting cylinder 18. The lower end of the connecting cylinder 18 is rotatably connected to a universal joint 32, and the lower end of the universal joint 32 is rotatably connected to a connecting shaft 33. Multiple symmetrically arranged connecting rods 34 are fixedly connected to the surface of the connecting shaft 33. Each connecting rod 34 is fixedly connected to the inner wall of the drain bucket 19, connecting the rotating rod 11 and the connecting shaft 33. This allows for power transmission at different angles, ensuring that the power of the rotating rod 11 is stably transmitted to the drain bucket 19.

[0028] Furthermore, a drying chamber 25 is fixedly connected to the upper surface of the base plate 1, a baffle 26 is fixedly connected to the upper surface of the drying chamber 25, and a support block 3 is fixedly connected to the upper surface of the drying chamber 25. The support block 3 is fixedly connected to the surface of the slide 24. One end of the support block 3 is fixed to the upper surface of the drying chamber 25, and the other end is fixedly connected to the slide 24, providing a stable mounting point for the slide 24, bearing the weight of the seeds after dehydration and the sliding impact force, preventing the slide 24 from deforming or sagging, and ensuring the stability of the seed transfer path.

[0029] Furthermore, the upper ends of the fixed support plate 10 and the first switch valve 17 are both provided with fan-shaped holes, and the left ends of the fixed circular plate 22 and the second switch valve 23 are both provided with semi-circular holes. The upper ends of the fixed support plate 10 and the first switch valve 17 are both provided with fan-shaped holes, and the two are connected by rotation. When the fan-shaped holes are aligned, a complete discharge channel is formed, and when they are misaligned, the channel is completely closed. The left ends of the fixed circular plate 22 and the second switch valve 23 are both provided with semi-circular holes, and the two are connected by rotation. When the semi-circular holes are aligned, a complete circular discharge port is formed, and when they are misaligned, the port is closed.

[0030] Working principle: Open the opening plate 8, put the rapeseed seeds into the conical cylinder 6, start the motor 27, and drive the drive shaft 28 to drive the drive wheel 29 to rotate. The drive wheel 29 simultaneously engages the upper driven wheel 30 and the lower driven wheel 31. The upper driven wheel 30 drives the rotating rod 11 to rotate, and the lower driven wheel 31 drives the rotating tube 12 to rotate. Since the rotating rod 11 and the rotating tube 12 are connected by a reciprocating thread transmission, the magnetic ring 35 moves up and down along the rotating rod 11. The movement of the magnetic ring 35 causes it to generate electromagnetic induction with the coil 9 sleeved on the surface of the conical cylinder 6, generating a current. This current is transmitted to the heating coil 21. During this process, the blades 13 on the surface of the magnetic ring 35 stir the seeds to ensure uniform coating. After coating is completed, open the switch valve 17 to allow the fixed tray to rotate. Aligning the fan-shaped hole of switch valve 17 with the seed, the seed falls into the connecting cylinder 18 and enters the draining bucket 19. The lower end of the rotating rod 11 drives the draining bucket 19 to rotate at high speed through the universal joint 32 and the connecting shaft 33, realizing centrifugal dehydration. At the same time, the heating coil 21 uses the current generated by electromagnetic induction to heat up the seeds in the draining bucket 19, accelerate the evaporation of moisture, and shorten the time for the subsequent drying process. After dehydration, switch valve 23 is opened, so that the fixed circular plate 22 is aligned with the semi-circular hole of switch valve 23. The seed slides into the drying box 25 along the slide 24. The drying box 25 performs the final drying treatment on the seed. During this process, the baffle 26 and the support block 3 ensure the stability of the structure, ensure the smooth transfer and drying of the seed, and complete the entire coating and drying process.

[0031] The foregoing description enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
