Description

Technical Field

[0001] The utility model relates to the field of drying equipment, in particular to a grain processing and drying equipment. Background Technique

[0002] Grain processing refers to the process of processing raw grains (such as paddy, wheat, corn, etc.) through processes such as cleaning, hulling, peeling, grinding, and screening into finished grains of different grades in granular or powdery form. Grain processing machinery is the key equipment used in this process, and they can efficiently complete various processing tasks to ensure the quality and safety of grain products.

[0003] A dryer is a device used to remove excess moisture from grains during the grain processing process. Grains often contain a high level of moisture after harvest, and if not dried in time, it is easy to cause mildew and a decline in quality. Therefore, the dryer plays a crucial role in grain processing. The working principle of the dryer is usually to generate heat by burning fuel or using electric energy, etc., heat the air inside the dryer, introduce the heated air into the dryer through the air duct, conduct heat exchange with the grains, take away the moisture in the grains, and the wet air generated during the drying process is discharged through the dehumidification system. At the same time, fresh air is supplemented to continue the drying process, forming a cycle. The dryer can quickly remove the excess moisture in the grains, shorten the drying time, and by precisely controlling parameters such as the drying temperature and humidity, it can ensure that the dried grains reach the ideal moisture content, maintaining their nutritional value and quality. The dryer can reduce losses caused by mildew, pests, etc., and improve the utilization rate and economic value of grains.

[0004] In order to ensure the smooth circulation of moisture in grains, traditional dryers usually have multiple groups of ventilation holes arranged at equal intervals on the outer wall, so that water vapor can be discharged from the device smoothly through these ventilation holes. The long-term circulation of water vapor will cause dust to adhere inside the ventilation holes, thereby affecting the continued use of the device and reducing the use efficiency of the device. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide a grain processing and drying equipment to solve the technical problems mentioned in the above background technique.

At the same time, through the setting of the transmission component, when the transmission cylinder and the linkage cylinder encounter the limitation of the air duct, they can still rotate smoothly through the drive of multiple transmission rods and can still rotate under the drive of the linkage ring, making the cleaning efficiency of the brushes better and avoiding the influence of the air duct on the brushes.

[0010] Further, the transmission component includes a spring, a transmission block, a connecting rod and a brake rod. A spring is installed in the transmission cylinder, and a transmission block corresponding to the spring is slidably installed in the transmission cylinder.

[0011] By adopting the above technical solution, it is ensured that under the action of the spring, the transmission block can smoothly slide out of the transmission cylinder.

[0012] Further, the end of the transmission block is rotatably installed with a connecting rod, the other end of the connecting rod is rotatably connected to the end of the brake rod, and the brake rod is rotatably connected to the transmission cylinder.

[0013] By adopting the above technical solution, it is ensured that the rotation of the brake rod can smoothly drive the transmission block and at the same time release the restriction of the transmission block on the linkage cylinder.

[0014] Further, the bottom of the transmission block is designed with an inclined side, two groups of connecting rods are symmetrically arranged on the outer wall of the transmission cylinder 5, the center position of the brake rod is rotatably connected to the transmission cylinder, and the center of the bottom of the brake rod and the center of the air duct are on the same plane.

[0015] By adopting the above technical solution, it is ensured that the rotation of the brake rod can first release the restriction between the transmission cylinder and the linkage cylinder.

[0016] Further, multiple groups of transmission rods are arranged at equal angles on the outer wall of the transmission ring. The ends of the two groups of brushes are designed in a semicircle, and the ends of the two groups of brushes close to the transmission component are in contact with each other.

[0017] By adopting the above technical solution, it is ensured that the dust in the air holes on the outer wall of the grain dryer can be completely cleaned between the two groups of brushes.

[0018] Further, the end of the linkage cylinder is designed with an inclined edge parallel to the end of the transmission block, and the end of the transmission cylinder is designed with a corresponding inclined edge, and the end of the transmission cylinder does not contact the end of the linkage cylinder.

[0027] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.

[0028] The embodiments of the present utility model will be described below according to the overall structure of the present utility model.

[0029] A grain processing and drying device, such asFigure 1 - Figure 4 As shown in the figure, it includes a grain dryer 1. A transmission ring 2 is rotatably installed on the outer wall of the grain dryer 1. A transmission rod 3 is fixedly installed on the outer wall of the transmission ring 2. The end of the transmission rod 3 is rotatably installed with a transmission cylinder 4. A linkage ring 11 is rotatably installed on the outer wall of the grain dryer 1. A linkage rod 10 corresponding to the transmission rod 3 is fixedly installed on the outer wall of the linkage ring 11. The end of the linkage rod 10 is rotatably installed with a linkage cylinder 9. A transmission component for the user to drive the linkage ring 11 is installed in the transmission cylinder 4. Brushes 12 are fixedly installed on the outer walls of the transmission rod 3 and the linkage rod 10. When the grain dryer 1 is working, the motor drives the transmission ring 2 to start rotating. At this time, the transmission rod 3 on the outer wall of the transmission ring 2 moves simultaneously, thereby driving the transmission cylinder 4 to start rotating. At this time, under the transmission of the transmission block 6, the linkage cylinder 9 and the linkage rod 10 start rotating simultaneously, causing the linkage ring 11 to move simultaneously. At this time, as the motor in the grain dryer 1 continues to rotate, the transmission rod 3 and the linkage rod 10 drive the brushes 12 on the outer walls to start rotating. At this time, under the cleaning of the brushes 12, the dust in the air vents on the outer wall of the grain dryer 1 is cleaned by the brushes 12.

[0030] Please refer to Figure 2 , a torsion spring for driving the transmission cylinder 4 is installed in the transmission rod 3, and a torsion spring for driving the linkage cylinder 9 is installed in the linkage rod 10. Under the restriction of the air duct, after the transmission cylinder 4 and the linkage cylinder 9 rotate, they can be reset smoothly through the action of the torsion spring, ensuring that when the air duct does not restrict the transmission cylinder 4 and the linkage cylinder 9, they can be reset smoothly.

[0031] Please refer to Figure 2 , the transmission component includes a spring 5, a transmission block 6, a connecting rod 7 and a brake rod 8. A spring 5 is installed in the transmission cylinder 4, and a transmission block 6 corresponding to the spring 5 is slidably installed in the transmission cylinder 4. Under the action of the self-stress of the spring 5, the transmission block 6 starts to move towards the end of the transmission cylinder 4 away from the transmission rod 3, ensuring that under the action of the spring 5, the transmission block 6 can smoothly slide out of the transmission cylinder 4.

[0032] Please refer to Figure 2 , the end of the transmission block 6 is rotatably installed with a connecting rod 7, the other end of the connecting rod 7 is rotatably connected to the end of the brake rod 8, and the brake rod 8 is rotatably connected to the transmission cylinder 4. Under the restriction of the transmission cylinder 4, when the brake rod 8 rotates, the transmission block 6 is driven to slide in the transmission cylinder 4 through the linkage of the connecting rod 7, ensuring that the rotation of the brake rod 8 can smoothly drive the transmission block 6 to release the restriction of the transmission block 6 on the linkage cylinder 9 at the same time.

[0033] Please refer to Figure 2, the bottom of the transmission block 6 is designed with a bevel edge, and there are two groups of connecting rods 7 symmetrically arranged on the outer wall of the transmission cylinder 45. The center position of the brake rod 8 is rotatably connected to the transmission cylinder 4, and the center of the bottom of the brake rod 8 and the center of the air guiding pipe are on the same plane. Through multiple groups of connecting rods 7, the transmission block 6 can be driven to move better. Under the action of the air guiding pipe, the end of the brake rod 8 first impacts the air guiding pipe, ensuring that the restriction between the transmission cylinder 4 and the linkage cylinder 9 can be released first through the rotation of the brake rod 8.

[0034] Please refer to Figure 3 and Figure 4 , multiple groups of transmission rods 3 are arranged at equal angles on the outer wall of the transmission ring 2. The ends of the two groups of brushes 12 are designed as semi - circles, and the ends of the two groups of brushes 12 close to the transmission assembly are in contact. The arrangement of multiple transmission rods 3 enables the remaining multiple groups to still be driven when one group of transmission cylinders 4 and linkage cylinders 9 rotate, ensuring that the dust in the air vents on the outer wall of the grain dryer 1 can be completely cleaned between the two groups of brushes 12.

[0035] Please refer to Figure 3 , the end of the linkage cylinder 9 is designed with a bevel edge parallel to the end of the transmission block 6, and the end of the transmission cylinder 4 is designed with a corresponding bevel edge. And the end of the transmission cylinder 4 does not contact the end of the linkage cylinder 9. When the transmission cylinder 4 and the linkage cylinder 9 collide, through the inclined design of the end of the transmission block 6, it is ensured that the transmission block 6 can smoothly enter the linkage cylinder 9 under the action of the impact force, and then drive the linkage cylinder 9 again.

[0036] The working principle of the present utility model is as follows: When the grain dryer 1 is working, the transmission ring 2 is driven to rotate by the motor. At this time, the transmission rods 3 on the outer wall of the transmission ring 2 move simultaneously, and then drive the transmission cylinder 4 to start rotating. At this time, under the transmission of the transmission block 6, the linkage cylinder 9 and the linkage rod 10 start rotating simultaneously, making the linkage ring 11 move simultaneously. At this time, with the continuous rotation of the motor in the grain dryer 1, the transmission rods 3 and the linkage rods 10 drive the brushes 12 on the outer wall to start rotating. At this time, the dust in the air vents on the outer wall of the grain dryer 1 is cleaned by the brushes 12.

[0037] With the continuous rotation of the transmission ring 2, the transmission cylinder 4 gradually comes into contact with the air induction pipeline provided in the grain dryer 1. At this time, one end of the brake lever 8 is restricted by the air induction pipeline and starts to rotate on the outer wall of the transmission cylinder 4 as the transmission lever 3 rotates. At this time, the connecting rod 7 at the other end of the brake lever 8 starts to drive the transmission block 6 at the other end of the connecting rod 7 to slide inside the transmission cylinder 4 as the brake lever 8 rotates, and at the same time starts to compress the spring 5 inside the transmission cylinder 4. Finally, with the rotation of the brake lever 8, the transmission block 6 is separated from the linkage cylinder 9. At this time, the brake lever 8 stops rotating. With the continuous restriction of the air induction pipeline and without the restriction of the transmission block 6, the transmission cylinder 4 and the linkage cylinder 9 start to rotate. At this time, the brush 12 is driven to start rotating. Due to the continuous rotation of the transmission ring 2, at this time, multiple groups of transmission levers 3 and linkage levers 10 on the outer wall of the transmission ring 2 start to drive the linkage ring 11 to rotate simultaneously under the restriction of the transmission block 6. At this time, the separated transmission cylinder 4 and linkage cylinder 9 start to slide on the outer wall of the air induction pipeline. Finally, the transmission cylinder 4 and the linkage cylinder 9 slide out of the air induction pipeline. At this time, without the restriction of the air induction pipeline, under the action of the torsion springs in the transmission lever 3 and the linkage lever 10, the transmission cylinder 4 and the linkage cylinder 9 start to reset. At the same time, under the action of the spring 5 inside the transmission cylinder 4, the transmission block 6 starts to slide inside the transmission cylinder 4, and then drives the brake lever 8 to reset through the connecting rod 7. At this time, with the rotation of the transmission cylinder 4 and the linkage cylinder 9 under the action of the torsion spring, finally, the transmission block 6 inside the transmission cylinder 4 collides with the linkage cylinder 9. Due to the impact force, since the inclined sides of the transmission block 6 and the linkage cylinder 9 start to squeeze each other, it is ensured that the transmission block 6 can smoothly enter the linkage cylinder 9 under the action of the impact force, and then drive the linkage cylinder 9 again.
