[0002] During corn processing, the corn hilum is usually mixed with impurities such as corn grits and broken kernels, making it impossible to obtain corn hilum with high purity.

[0003] Currently, corn hilum screening mostly uses single vibrating screens, which have limited separation accuracy and are prone to waste; or traditional air separation is used, but unstable airflow control leads to low separation accuracy. Some more complex equipment suffers from complex structures, high costs, and difficulty in adapting to different materials.

The machine separates corn piths from other substances through an air separation structure, and then classifies and collects corn piths according to size through grading and screening, thereby improving screening efficiency and realizing automated separation and screening.

[0006] To solve the above problems, the technical solution of the present invention is: a corn germ screening machine, comprising; An air classifier and a vibrating box are provided, with a screw conveyor between the air classifier and the vibrating box. The upper part of the air classifier is provided with a feeding structure, and the lower part of the air classifier is provided with an air classifier structure. Motor 1 is fixedly connected to the bottom of the vibrating box. A rotating shaft is fixedly connected to the upper output end of the motor 1. Two movable ring groove frames and one fixed ring groove frame are sequentially fitted on the surface of the rotating shaft from top to bottom. A sieve plate is placed inside the movable ring groove frame. A limiting structure is provided between the rotating shaft and the movable annular groove frame; A control structure is provided on one side of the vibration box and is used to control the up and down movement of the movable ring groove frame.

[0007] Preferably, the control structure includes: Motor 2, the output end of which is fixedly connected to a turntable, and the other end of which is fixedly connected to a connecting rod; A connecting plate, one end of which is fixedly connected to a fixing frame, and the other end of which is fixedly connected to four corners of four adjusting rods. Each pair of adjusting rods is fixedly connected to two movable annular groove frames, and one end of each connecting rod is rotatably connected to the inside of the connecting plate.

[0008] Preferably, the vibration box has four sets of vertical holes on the side near the fixed frame. The adjusting rod is slidably connected inside the vertical holes. A protective shell is fixedly connected to one side of the vibration box. One end of the motor is fixedly connected to the inside of the protective shell. Two mounting plates are fixedly connected to both ends inside the protective shell. A vertical rod is fixedly connected between the two mounting plates on the same side. The two ends of the connecting plate are sleeved on the surface of the vertical rod. A spring is sleeved on the surface of the vertical rod. The spring is located between the mounting plate and the connecting plate.

[0009] Preferably, both the movable annular groove frame and the screen plate are provided with mesh holes, with the upper mesh holes being larger than the lower mesh holes. Both the movable annular groove frame and the fixed annular groove frame have an opening on one side, and the opening is provided with a discharge structure.

[0010] Preferably, the discharge structure includes a discharge cylinder, and a sliding baffle is provided on one side of the discharge cylinder.

[0011] Preferably, the limiting structure includes a sleeve, the sleeve is fixedly connected inside the center of the sieve plate, the sleeve is slidably sleeved on the surface of the rotating shaft, a thin plate is fixedly connected inside the sleeve, a cross keyway is formed inside the thin plate, and a cross key that mates with the cross keyway is fixedly connected inside the rotating shaft.

Detailed Implementation

[0024] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0025] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0026] To make the content of this invention easier to understand, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] like Figure 1-7 As shown, a corn seed screening machine includes an air separator 1 and a vibrating box 2. A screw conveyor 3 is provided between the air separator 1 and the vibrating box 2. The upper end of the air separator 1 is provided with a feed inlet 37, and the upper end of the vibrating box 2 is provided with a feed inlet 38. The output end of the screw conveyor 3 is connected to the feed inlet 38.

[0028] In this embodiment, corn kernels and related products can be added to the air classifier 1 through the feed inlet 37. After air classification, heavier corn residue and other substances can be removed, allowing the corn kernels to enter the vibrating box 2 through the screw conveyor 3 and the feed inlet 38 for vibration grading and screening.

[0029] The upper part of the air classifier 1 is provided with a feeding structure 4, and the lower part of the air classifier 1 is provided with an air classifier structure 5. The feeding structure 4 includes multiple sets of staggered inclined plates 31, which are rotatably connected to the inside of the air classifier 1. The lower end of the inclined plate 31 is fixedly connected with a spring 32, and the other end of the spring 32 is fixedly connected to the inner wall of the air classifier 1. The air classifier structure 5 includes: a fan 33 fixedly connected to one side of the air classifier 1, and an air duct 34 at the output end of the fan 33. The air duct 34 extends into the inside of the air classifier 1 and is located below the feeding structure 4. The receiving port 36 is connected between the air classifier 1 and the inlet of the screw conveyor 3. The receiving box 35 is located at the bottom of the inside of the air classifier 1.

[0030] In this embodiment, when a large amount of corn kernels and related products fall onto the inclined plate 31 through the feed inlet 37, the inclined plate 31 transmits pressure to the spring 32, which is compressed to prevent damage. When the amount of material is large, the inclination angle of the inclined plate 31 can be increased to accelerate the falling of the material. Multiple sets of staggered inclined plates 31 can ensure that the material falls evenly and avoids being affected during air separation. When the material falls to the blower 33, the blower 33 blows the corn kernels in the material into the receiving port 36 through the air duct 34, so that the corn kernels without other materials enter the vibrating box 2 through the screw conveyor 3.

[0031] Motor 6 is fixedly connected to the bottom of the vibrating box 2. The upper output end of motor 6 is fixedly connected to a rotating shaft 7. Two movable ring groove frames 9 and one fixed ring groove frame 8 are sequentially fitted on the surface of the rotating shaft 7 from top to bottom. A screen plate 10 is placed inside the movable ring groove frame 9. Both the movable ring groove frame 9 and the screen plate 10 have mesh holes, and the upper mesh holes are larger than the lower mesh holes. An opening 24 is opened on one side of both the movable ring groove frame 9 and the fixed ring groove frame 8. A discharge structure is provided at the opening 24. The discharge structure includes a discharge cylinder 25. A sliding baffle 26 is provided on one side of the discharge cylinder 25.

[0032] In this embodiment, the starting of motor 6 can drive the rotating shaft 7 to rotate, thereby driving the screen plate 10 to rotate. The corn kernels falling on the screen plate 10 are graded and screened as the screen plate 10 rotates, and enter the discharge cylinder 25 through the opening 24 for graded and classified collection. The baffle 26 can slide to facilitate discharge.

[0033] A control structure 12 is located on one side of the vibration box 2 and is used to control the up-and-down movement of the movable ring groove frame 9. The control structure 12 includes a second motor 13, the output end of which is fixedly connected to a turntable 14, and a connecting rod 15 is fixedly connected to the edge of the other end of the turntable 14. A fixed frame 17 is fixedly connected to one end of a connecting plate 16, and four adjusting rods 18 are fixedly connected to the four corners of the other end of the fixed frame 17. Each pair of adjusting rods 18 is fixedly connected to two movable ring groove frames 9, and one end of the connecting rod 15 is rotatably connected to the inside of the connecting plate 16. Four sets of vertical holes 19 are opened on the side of the vibration box 2 near the fixed frame 17, and the adjusting rods 18 are slidably connected to the inside of the vertical holes 19.

[0034] In this embodiment, the start of motor 13 can drive turntable 14 to rotate, thereby driving connecting rod 15 to rotate with turntable 14. Under the restriction of vertical hole 19, connecting rod 15 drives connecting plate 16 to move up and down, thereby driving fixed frame 17 and adjusting rod 18 to move up and down, thereby driving movable ring groove frame 9 to move up and down, which can improve the screening efficiency of screen plate 10.

[0035] Furthermore, a protective shell 23 is fixedly connected to one side of the vibration box 2, and one end of the motor 2 13 is fixedly connected to the inside of the protective shell 23. Two mounting plates 20 are fixedly connected to both ends inside the protective shell 23. A vertical rod 21 is fixedly connected between the two mounting plates 20 on the same side. The two ends of the connecting plate 16 are sleeved on the surface of the vertical rod 21, and a spring 22 is sleeved on the surface of the vertical rod 21. The spring 22 is located between the mounting plate 20 and the connecting plate 16 respectively.

[0036] In this embodiment, the protective shell 23 is used to protect the control structure 11, and when the connecting plate 16 moves up and down, the spring 22 can absorb the power and react on the connecting plate 16 to avoid damage to the connecting plate 16 and provide a vibration effect.

[0037] The limiting structure 11 is disposed between the rotating shaft 7 and the movable ring groove frame 9; the limiting structure 11 includes a sleeve 27, the sleeve 27 is fixedly connected inside the center of the sieve plate 10, the sleeve 27 is slidably sleeved on the surface of the rotating shaft 7, a thin plate 28 is fixedly connected inside the sleeve 27, a cross keyway 29 is opened inside the thin plate 28, and a cross key 30 that mates with the cross keyway 29 is fixedly connected inside the rotating shaft 7.

[0038] In this embodiment, when motor 6 starts, it drives the rotating shaft 7 to rotate, thereby driving the cross key 30 to rotate. The cross key 30 can drive the sleeve 27 to rotate through the cross key groove 29, thereby driving the screen plate 10 to rotate. When the control structure 12 drives the movable ring groove frame 9 to move up and down, the screen plate 10 will also move up and down. At this time, the thin plate 28 slides up and down on the surface of the cross key 30 through the cross key groove 29, thereby the sleeve 27 slides up and down on the surface of the rotating shaft 7.

[0039] In practical use, when the material falls onto the inclined plate 31 through the feed inlet 37, the inclined plate 31 transmits pressure to the spring 32, compressing the spring and preventing damage. When the material volume is large, the inclination angle of the inclined plate 31 can be increased to accelerate the material's descent. Multiple staggered inclined plates 31 ensure uniform material descent, preventing interference during air separation. When the material reaches the blower 33, the activated blower 33 blows the corn kernels into the receiving port 36 through the air duct 34, allowing the corn kernels without other material to enter the vibrating box 2 via the screw conveyor 3. The motor 6 starts, driving the rotating shaft 7 to rotate, which in turn drives the cross key 30 to rotate. The cross key 30, through the cross key groove 29, drives the sleeve 27 to rotate, thereby driving... The sieve plate 10 rotates, and the corn kernels falling onto the sieve plate 10 are graded and screened as the sieve plate 10 rotates. They then enter the discharge cylinder 25 through the opening 24 for grading and collection. The motor 2 13 starts and drives the turntable 14 to rotate, which in turn drives the connecting rod 15 to rotate with the turntable 14. Under the restriction of the vertical hole 19, the connecting rod 15 drives the connecting plate 16 to move up and down, which in turn drives the fixed frame 17 and the adjusting rod 18 to move up and down, which in turn drives the movable ring groove frame 9 to move up and down, which can improve the screening efficiency of the sieve plate 10. When the control structure 12 drives the movable ring groove frame 9 to move up and down, the sieve plate 10 will also move up and down. At this time, the thin plate 28 slides up and down on the surface of the cross key 30 through the cross key groove 29, so that the sleeve 27 slides up and down on the surface of the rotating shaft 7.

The main controller can be a conventional known device such as a computer for control.

[0041] The present invention and its embodiments have been described above.

In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
