Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain processing technology, specifically a cleaning and screening device for grain processing. Background Technology
[0002] Grains are the main source of energy needed by the human body. The world's main grains include rice, wheat, rye, sorghum, corn and millet. Grain processing refers to the business activities of transforming raw grains into semi-finished grains or finished grains, or vice versa.
[0003] As people's requirements for food increase, the quality of grain has become a major concern. During the processing of grain, screening devices are needed to remove larger impurities. However, existing screening devices are prone to clogging at the feed inlet after the grain is poured in. Furthermore, during the screening process, impurities can easily clog the screen holes, preventing the grain from being screened properly. Utility Model Content
[0004] The purpose of this invention is to provide a cleaning and screening device for grain processing to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a cleaning and screening device for grain processing, comprising a box body, a feeding hopper fixedly connected to the top of one end of the box body, a connecting cylinder fixedly connected to the interior of the box body near the feeding hopper, the bottom of the feeding hopper communicating with the connecting cylinder, a first motor fixedly connected to the outer side of the top of the box body, a first connecting shaft fixedly connected to the output end of the first motor, one end of the first connecting shaft rotatably connected to the interior of the bottom of the feeding hopper, and a plurality of rotating blades fixedly connected to the outer side of the first connecting shaft.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] This utility model provides a technical solution: such as Figure 1 , Figure 2 and Figure 3 As shown in this embodiment, a grain processing cleaning and screening device includes a housing 1. A feeding hopper 2 is fixedly connected to the top of one end of the housing 1. A connecting cylinder 7 is fixedly connected to the inside of the housing 1 near the feeding hopper 2. The bottom of the feeding hopper 2 is connected to the connecting cylinder 7. A first motor 3 is fixedly connected to the outside of the top of the housing 1. A first connecting shaft 6 is fixedly connected to the output end of the first motor 3. One end of the first connecting shaft 6 is rotatably connected to the inside of the bottom of the feeding hopper 2. Several rotating blades 15 are fixedly connected to the outside of the first connecting shaft 6. Grain is fed into the feeding hopper 2 for screening. The grain enters the connecting cylinder 7 through the feeding hopper 2. During this process, the first motor 3 drives the rotating blades 15 to rotate through the first connecting shaft 6, agitating the grain so that it can fall smoothly into the connecting cylinder 7 without clogging the feeding hopper 2.
[0023] A second motor 4 is fixedly connected to the outer side of one end of the housing 1. A second connecting shaft 8 is fixedly connected to the output end of the second motor 4. The second connecting shaft 8 is located inside the connecting cylinder 7, and a conveying blade 9 is fixedly connected to the outer side of the second connecting shaft 8. When the grain enters the connecting cylinder 7, the second motor 4 drives the conveying blade 9 to rotate through the second connecting shaft 8 to convey the grain.
[0024] like Figure 2 and Figure 4 As shown, two symmetrically arranged hanging plates 10 are fixedly connected to the top inside the box 1. A screening cylinder 11 is rotatably connected between the two hanging plates 10. One end of the connecting cylinder 7 is connected to the screening cylinder 11. The screening cylinder 11 is placed inside the two hanging plates 10. The hanging plates 10 are used to suspend the screening cylinder 11 so that it can be connected to the connecting cylinder 7.
[0025] One end of the screening cylinder 11 is fixedly connected to the cylinder cover 14, and one end of the second connecting shaft 8 is fixedly connected to the middle of one side of the cylinder cover 14. Several sets of screening holes 16 are opened on the surface of the screening cylinder 11. The screening holes 16 are used to screen the grain. Since the second connecting shaft 8 is connected to the cylinder cover 14, the second motor 4 drives the screening cylinder 11 to rotate through the second connecting shaft 8. During the rotation of the screening cylinder 11, the grain will turn over inside the screening cylinder 11 and then pass through the screening holes 16. Larger impurities in the grain will remain inside the screening cylinder 11.
[0026] like Figure 1 and Figure 2As shown, a discharge hopper 5 is fixedly connected to the bottom of the box 1. The feed end of the discharge hopper 5 is located directly below the screening cylinder 11, and the discharge end of the discharge hopper 5 is located on the surface of the bottom of the box 1. The grain after being screened by the screening cylinder 11 will enter the discharge hopper 5 through the feed end of the discharge hopper 5 and then be discharged from the discharge end of the discharge hopper 5.
[0027] A through groove 13 is provided on the top of one end of the box body 1. The through groove 13 is located near the cylinder cover 14, and a door is hinged to one end of the through groove 13. By opening the door, the staff can disassemble and remove the screening cylinder 11 through the through groove 13 to clean the impurities inside the screening cylinder 11.
[0028] like Figure 4 and Figure 5 As shown, a connecting plate 12 is fixedly connected to the top between the two hanging plates 10, and two scrapers 17 are fixedly connected to the bottom of the connecting plate 12. The two scrapers 17 are in contact with the outer surface of the screening cylinder 11. During the rotation of the screening cylinder 11, if a large impurity blocks the screening hole 16, the impurity will come into contact with the scraper 17, and the scraper 17 will apply pressure to the impurity and push it back into the screening cylinder 11 to avoid the screening hole 16 from being blocked and the grain being unable to be screened.
[0029] This utility model provides a grain processing cleaning and screening device. The specific working principle is as follows: Grain is fed into the feed hopper 2 for screening. The grain enters the connecting cylinder 7 through the feed hopper 2. During this process, the first motor 3 drives the rotating blade 15 to rotate through the first connecting shaft 6, which agitates the grain so that it can fall smoothly into the connecting cylinder 7 without clogging the feed hopper 2. After the grain enters the connecting cylinder 7, the second motor 4 drives the conveying blade 9 to rotate through the second connecting shaft 8, which conveys the grain into the screening cylinder 11. Since the second connecting shaft 8 is connected to the cylinder cover 14, the second motor 4 drives the screening cylinder 11 to rotate through the second connecting shaft 8. During the rotation of the screening cylinder 11, the grain will turn over inside the screening cylinder 11 and then pass through the screening holes 16. Larger impurities in the grain will remain inside the screening cylinder 11. The grain that has passed through the screening holes 16 will enter the discharge hopper 5 from the feed end of the discharge hopper 5 and then be discharged from the discharge end of the discharge hopper 5.
