Description

Technical Field

[0001] This utility model relates to the field of oat processing technology, and in particular to an oat processing selection and grading device. Background Technology

[0002] With the increasing awareness of health, people are growing their demand for nutritious foods. Oats, rich in dietary fiber, protein, vitamins and various minerals, have become a popular healthy grain. In the oat processing process, selection and grading are crucial steps that directly affect the quality of the final product and its market competitiveness.

[0003] Traditional grading devices mostly use a single vibration mode with a regular vibration pattern. During the screening process, the oats cannot be fully tumbled and bounced, resulting in incomplete contact between the oats and the sieve holes. This leads to incomplete separation of particles of different sizes, resulting in low grading efficiency and accuracy, which makes it difficult to meet the market demand for high-quality oats. In order to solve the above problems, this utility model provides an oat processing and grading device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an oat processing selection and grading device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An oat processing and grading device includes a grading box, an installation frame fixedly connected to the bottom of the grading box, return springs fixedly connected to the four corners of the upper surface of the installation frame, a common connecting frame fixedly connected to the upper ends of the four return springs, a screening box movably connected inside the connecting frame, a screening groove opened at the lower end of the screening box, a power component inside the grading box, a top plate fixedly connected to the upper surface of the grading box, a feeding funnel fixedly connected to the upper end of the top plate, an installation shell fixedly connected to one side of the grading box, and a discharge inclined plate fixedly connected inside the installation frame.

[0007] As a further improvement of this utility model, the power assembly includes two rotating rods rotatably connected inside the grading box via bearings. Two cams are fixedly connected to the surface of each of the two rotating rods. Two semi-circular impact blocks adapted to the cams are fixedly connected to both sides of the connecting frame. Synchronous pulleys are fixedly connected to the same end of each of the two rotating rods. The same synchronous belt is sleeved on the surface of the two synchronous pulleys.

[0008] As a further improvement of this utility model, a servo motor is fixedly installed inside the mounting shell, and the power end of the servo motor passes through the grading box and is connected to one of the rotating rods.

[0009] As a further improvement of this utility model, a sleeve rod is fixedly connected to the lower end of the inside of the reset spring, and a guide rod is fixedly connected to the upper end of the inside of the reset spring, and the guide rod is movably connected inside the sleeve rod.

[0010] As a further improvement of this utility model, a discharge chute is provided at the lower end of the front side of the grading box, and the discharge chute is connected to the discharge inclined plate.

[0011] As a further improvement of this utility model, a protective door is hinged to the upper end of the front of the grading box, and a handle is fixedly connected to the front of the protective door.

[0012] As a further improvement of this utility model, sliding grooves are provided on both sides inside the connecting frame, and sliders that are adapted to the sliding grooves are fixedly connected to both sides of the screening box.

[0013] As a further improvement of this utility model, each of the four corners of the lower surface of the grading box is fixedly connected to a support base, and each of the four support bases is fixedly connected to a buffer base at its lower end.

[0014] The beneficial effects of this utility model are:

[0015] By setting up a power assembly, during operation, the four cams fixedly connected to the two rotating rods have different initial angles. Driven by a servo motor, the two rotating rods rotate synchronously through a synchronous wheel and a synchronous belt, which in turn drives the four cams to strike the semi-circular impact blocks on both sides of the connecting frame in sequence. This sequential impact of cams with different initial angles, combined with the elasticity of the return spring, causes the screening box to vibrate in multiple directions and irregularly. This vibration mode allows the oats to tumble and jump fully in the screening box, resulting in more comprehensive contact between the oats and the sieve holes, more thorough separation of particles of different sizes, improved grading efficiency and accuracy, and effectively enhanced quality of oat products.

[0016] By incorporating a reset spring, the internal sleeve and guide rod structure provides precise guidance for the spring's extension and retraction, effectively enhancing the structural stability of the entire grading device. During the vibration of the screening box, the reset spring continuously undergoes compression and extension movements. This stable structural design reduces the failure rate of the equipment during operation, lowers the risk of component damage, and thus extends the service life of the equipment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-3 An oat processing and grading device includes a grading box 1, a mounting frame 2 fixedly connected to the bottom of the grading box 1, return springs 3 fixedly connected to the four corners of the upper surface of the mounting frame 2, a connecting frame 4 fixedly connected to the upper ends of the four return springs 3, a screening box 5 movably connected inside the connecting frame 4, a screening groove 23 opened at the lower end of the screening box 5, a power component inside the grading box 1, a top plate 6 fixedly connected to the upper surface of the grading box 1, a feeding funnel 7 fixedly connected to the upper end of the top plate 6, a mounting shell 8 fixedly connected to one side of the grading box 1, and a discharge inclined plate 17 fixedly connected inside the mounting frame 2.

[0023] In this invention, the power assembly includes two rotating rods 9 rotatably connected inside the grading box 1 via bearings. The two rotating rods 9 are arranged in parallel and are securely mounted on both sides inside the grading box 1 via bearings. Two cams 10 are fixedly connected to the surface of each of the two rotating rods 9. The contour curve of the cams 10 can be optimized according to the vibration frequency and amplitude required for screening to ensure that a suitable impact force is generated on the connecting frame 4 during rotation, thereby achieving a high-efficiency screening effect. Two semi-circular impact blocks 11 adapted to the cams 10 are fixedly connected to both sides of the connecting frame 4. The surface of the semi-circular impact blocks 11 is smoothed to reduce the friction when in contact with the cams 10 and reduce energy loss. At the same time, its rounded shape can make the cams 10 more stable during impact and avoid generating excessive impact noise. Synchronous pulleys 12 are fixedly connected to the same end of each of the two rotating rods 9. The same synchronous belt 13 is sleeved on the surface of the two synchronous pulleys 12. The synchronous belt 13 can accurately transmit the rotation of the two synchronous pulleys 12, ensuring that the two rotating rods 9 rotate synchronously, thereby making the vibration of the screening box 5 more uniform and stable.

[0024] A servo motor 14 is fixedly installed inside the mounting housing 8. The power end of the servo motor 14 passes through the grading box 1 and is connected to one of the rotating rods 9. The servo motor 14 can precisely adjust the rotation speed according to different oat screening requirements, providing reliable power support for the entire grading device.

[0025] The lower end of the return spring 3 is fixedly connected to a sleeve rod 15, and the upper end of the return spring 3 is fixedly connected to a guide rod 16. The guide rod 16 is movably connected inside the sleeve rod 15. The fit clearance between the guide rod 16 and the sleeve rod 15 is precisely controlled to ensure that the guide rod 16 slides smoothly inside the sleeve rod 15, while avoiding shaking due to excessive clearance, which would affect the guiding effect of the return spring 3.

[0026] The lower end of the front of the grading box 1 is provided with a discharge chute 18, which is connected to the discharge ramp 17. The size and shape of the opening of the discharge chute 18 allow the small oat particles after screening to pass through smoothly. The discharge ramp 17 has a certain inclination angle, which allows the oats to slide down automatically by gravity without the need for additional power, thus improving the discharge efficiency. The upper end of the front of the grading box 1 is hinged to a protective door 19, and a handle 20 is fixedly connected to the front of the protective door 19. The handle 20 is convenient for the operator to hold.

[0027] Both sides of the connecting frame 4 are provided with sliding grooves 21. Both sides of the screening box 5 are fixedly connected with sliders 22 that are compatible with the sliding grooves 21. The surface of the sliding grooves 21 is finely processed, smooth and flat, which can reduce the friction generated by the screening box 5 during sliding. The four corners of the lower surface of the grading box 1 are fixedly connected with support seats 24. The lower ends of the four support seats 24 are fixedly connected with buffer bases 25. The buffer bases 25 are made of rubber and have good buffering and shock absorption performance. They can effectively absorb the vibration and impact generated by the device during operation, reduce the impact on the ground, and reduce the noise and wear of the device itself.

[0028] In use, the oats to be sorted and graded are added to the screening box 5 in the connecting frame 4 inside the grading box 1 through the feeding funnel 7 on the top plate 6. At this time, the four return springs 3 are in a naturally extended state, and the connecting frame 4 is in a relatively stable position under the support of the return springs 3. The four cams 10 on the two rotating rods 9 in the power assembly are in a specific initial state due to different initial angles. The servo motor 14 in the mounting shell 8 is started, and its power end drives one of the connected rotating rods 9 to rotate. Since the two rotating rods 9 have the same synchronous wheel 12 at one end and the same synchronous belt 13 is sleeved on their surfaces, the other rotating rod 9 rotates synchronously. As the rotating rod 9 rotates, the four cams 10 with different initial angles contact the semi-circular impact blocks 11 fixed on both sides of the connecting frame 4 in sequence. When they contact, the cams 10 apply a downward impact force to the connecting frame 4, causing the connecting frame 4 to... The lower compression return spring 3 drives the screening box 5 to move downward. The sleeve rod 15 at the lower end of the return spring 3 and the guide rod 16 at the upper end are movably connected, which can guide the extension and retraction direction of the return spring 3. After the cam 10 separates from the semi-circular impact block 11, the elastic force of the return spring 3 causes the connecting frame 4 and the screening box 5 to bounce upward. This is repeated, and the screening box 5 generates complex and irregular vibrations, allowing the oats to fully tumble and jump to achieve grading. Small oat particles fall through the sieve holes of the screening box 5 and slide down the discharge inclined plate 17 in the mounting frame 2 to the discharge trough 18 connected to the discharge inclined plate 17 at the lower front end of the grading box 1, where they are collected. After the work is completed, the protective door 19 can be opened by the handle 20 on the protective door 19 hinged to the front of the grading box 1. The screening box 5 can be taken out from the connecting frame 4 for further processing by using the cooperation of the sliders 22 on both sides of the screening box 5 and the sliding grooves 21 on both sides inside the connecting frame 4.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
