Technical Field

[0001] The utility model relates to the field of food processing, in particular to an energy-saving and efficient grain drying machine. Background Art

[0002] Grain dryers are equipment used to remove moisture from crops to improve their preservation and quality. They play an important role in agricultural production, especially during the harvest season when the weather is humid or when crops need to be dried quickly after harvest to prevent mildew and damage. The working principle of a grain dryer usually involves exposing wet crops to appropriate conditions through heating and ventilation to evaporate the moisture. Different types of grain dryers have different designs and working principles, including batch dryers, fluidized bed dryers, belt dryers, etc. Choosing a suitable dryer depends on factors such as the type and amount of crops, the drying speed requirements, and the available energy.

[0003] Due to design or operation problems, traditional dryers usually pile grains neatly on conveying equipment during drying, and achieve continuous drying through the conveying equipment, which ensures that the grain is dried while also ensuring the grain production efficiency. However, this drying method will cause the grain to pile up, resulting in uneven drying. The top part of the grain may be over-dried while the bottom part of the grain pile still contains too much moisture, failing to achieve the ideal drying effect, affecting production efficiency and timeliness. Therefore, an energy-saving and efficient grain dryer is proposed to solve the above problems. Utility Model Content

[0032] Specifically, the support frame 1 is used to connect and support its internal parts, the connecting shaft 2 is used to transmit power, and the two ends are connected to the eccentric shaft 3 to make the eccentric shaft 3 move synchronously, the connecting shaft 2 cooperates with the eccentric shaft 3 to generate eccentric force, driving the connecting rod 4 to move back and forth left and right, and the vibrating screen 5 is connected through the connection between the connecting rod 4 and the vibrating screen 5 to make the vibrating screen 5 vibrate continuously. The bottom of the vibrating screen 5 is a screen for screening out dust and debris attached to the grain. The four connecting rods 6 are mainly used to limit the vibrating screen 5 to ensure that the vibrating screen 5 can only move back and forth left and right without shaking. The outer shell 7 is used to protect its internal structure, and the heating rod 8 is used to generate heat and volatilize the moisture of the grain.

[0033] Reference Figure 3 - Figure 5 The cleaning component includes a waste frame 14, the front and rear sides of the waste frame 14 are fixedly connected between the inner sides of the two support frames 1, a waste trough 15 is fixedly connected to the bottom of the waste frame 14, a motor 16 is fixedly connected to the front end of the waste trough 15, a threaded rod 17 is fixedly connected to the output end of the motor 16, a scraper 18 is threadedly connected to the outer wall of the threaded rod 17, a discharge port 20 is opened on the front side of the inner wall of the waste trough 15, and the transmission component includes two connecting rods 3 9, the right sides of the two connecting rods 3 9 are fixedly connected to the left side of the shell 7, a linkage shaft 2 12 is rotatably connected between the two connecting rods 3 9, and the outer wall of the linkage shaft 2 12 is rotatably connected to a grain box 1 11, a linkage shaft 2 12 is rotatably connected inside the grain box 11, a conveyor belt 13 is sleeved between the linkage shaft 2 12 and the linkage shaft 12, and the linkage shaft 2 12 and the linkage shaft 1 2 are connected by a belt, and a grain box 2 10 is fixedly connected on the right side of the two support frames 1, and the top of the grain box 2 10 is located below the right side of the vibrating screen 5, and the inner bottom wall of the waste trough 15 is fixedly connected to a limit strip 19, and the bottom of the scraper 18 is slidably connected to the outside of the limit strip 19, and the front and rear ends of the threaded rod 17 are rotatably connected to the front and rear sides of the inner wall of the waste trough 15, and the bottom of the scraper 18 is slidably connected to the inner wall of the waste trough 15.

[0034] Specifically, the waste frame 14 is used to receive the dust and debris screened out from the vibrating screen 5. The dust and debris are all concentrated in the waste trough 15 through the inclined surface of the waste frame 14. The waste trough 15 is used to collect dust and debris. The motor 16 is used to drive the parts inside the waste trough 15 to work. The threaded rod 17 is used to drive the scraper 18 to move back and forth inside the waste trough 15. The limit bar 19 is used to limit the movement direction of the scraper 18, ensuring that the scraper 18 can only move back and forth without any random movement. The discharge port 20 is used to quickly remove dust and debris. The connecting rod three 9 is used to connect the transmission components. The grain box one 11 is used to place wet grain to be dried. The connecting shaft two 12 is used to drive the conveyor belt 13 to operate. The conveyor belt 13 rotates to transfer the grain in the grain box one 11 to the vibrating screen 5 for drying. The grain box two 10 is used to receive and place the dried grain that falls from the vibrating screen 5.

[0035] Working principle: when it is necessary to dry grain, first preheat the heating rod 8 through an external power supply, and pour the wet grain into the grain box 11 at the same time. When the heating rod 8 reaches the appropriate temperature, the conveyor belt 13 is controlled by the external power supply. When the conveyor belt 13 is running, the linkage shaft 12 will drive the linkage shaft 2 to rotate through the belt, and the linkage shaft 2 will drive the eccentric shaft 3 to rotate, and then it will push the connecting rod 4 to reciprocate left and right, and the connecting rod 4 will drive the vibrating screen 5 to vibrate left and right continuously. At this time, the partition on the conveyor belt 13 will continuously transfer the grain from the grain box 11 to the left side of the vibrating screen 5, and finally fall onto the vibrating screen 5. When vibrating, the grain piled together will be shaken apart, and the temperature of the heating rod 8 will make the grain evenly heated, which will speed up the drying process. Water evaporates, and the vibrating screen 5 is a slope inclined to the right. During the vibration process, the grain will slowly move to the right and eventually fall into the grain box 10. The vibrating screen 5 will screen out dust and debris during the vibration process. The dust and debris will be collected by the waste frame 14 and concentrated in the waste trough 15. When all the grain is dried, the motor 16 is controlled to rotate by an external power supply, driving the threaded rod 17 to rotate, and the scraper 18 will move from the back to the front. A trash can is placed under the discharge port 20. Dust and debris will eventually fall into the trash can through the push of the scraper 18. This drying method will not cause grain accumulation, solves the problem of uneven drying, which causes some grains to be over-dried while some still contain too much water, and effectively improves work efficiency.
