[0002] At present, with the progress of agricultural science and technology, the agricultural production capacity will continue to improve. And with the growth of the population and the improvement of the living standards of residents, the consumption demand for agricultural products will continue to grow. In particular, high-quality, safe and healthy agricultural products will be more favored by consumers.

[0003] In order to improve the quality of agricultural products and meet the market demand, an impurity removing device is usually used to remove impurities in agricultural products. At present, the impurity removing device usually separates impurities from agricultural products by the vibration of a vibrating screen, making the agricultural products roll and jump up and down on the screen, which is suitable for the impurity removal of various granular agricultural products, such as wheat, corn, soybeans, etc.

[0004] Although the current impurity removing device has a simple structure and is easy to operate, its vibration impurity removal can only shake the agricultural products up and down in one direction, resulting in low impurity removal efficiency and inability to perform multi-dimensional screening. When facing impurities with high viscosity, it cannot completely screen them out. Therefore, it needs to be improved and optimized. Summary of the Utility Model

[0016] 1.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] As Figures 1 to 8 shown, the present invention provides a impurity removal device for agricultural product processing, including a fixed platform 1, a blanking plate 2 is fixedly installed on the top of the fixed platform 1, and a screen 3 is arranged inside the fixed platform 1;

[0029] A vibration frame 4 is movably installed inside the fixed platform 1. Sliding blocks 5 are fixedly installed at the four corners of the vibration frame 4. Limit grooves 6 are opened at the four corners of the inner wall of the fixed platform 1. The sliding blocks 5 are movably installed inside the limit grooves 6. Chutes 10 are opened on the front and rear sides of the vibration frame 4. Moving blocks 9 are fixedly installed on the front and rear sides of the bottom of the screen 3. The two groups of moving blocks 9 are movably installed inside the chutes 10. Teeth 11 are opened on the left and right sides of the two groups of moving blocks 9;

[0030] The front and rear sections of the inner wall of the fixed platform 1 are rotatably installed with first vibration blocks 12. One ends of the two groups of first vibration blocks 12 are fixedly installed with first driving blocks 13. The front and rear sides of the inner wall of the fixed platform 1 are rotatably installed with second vibration blocks 14. The second vibration blocks 14 are located on the left side of the first vibration blocks 12. One ends of the two groups of second vibration blocks 14 are fixedly connected with second driving blocks 15. The two groups of second driving blocks 15 are fixedly connected through a transmission rod 16. The two groups of first driving blocks 13 are also fixedly connected through a transmission rod 16. There are two groups of transmission rods 16.

[0031] When impurity screening and removal operations are required, the staff add agricultural products on top of the sieve mesh 3 through the feeding plate 2. Then, the staff start the motor 18. The operation of the motor 18 drives the first driving wheel 17 to rotate. The first driving wheel 17 meshes with the transmission wheel 19, and the transmission wheel 19 and the second driving wheel 20 are connected by a transmission belt 21 for transmission, causing the second driving wheel 20 to rotate. At this time, the rotation directions of the first driving wheel 17 and the second driving wheel 20 are opposite. When the first driving wheel 17 and the second driving wheel 20 rotate one week, the first vibration block 12 and the second vibration block 14 rotate, lifting the vibration frame 4. And due to the elastic potential energy of the return spring 8, after the vibration frame 4 is lifted, the slider 5 moves downward along the return spring 8 for reset, completing a single up-and-down vibration. At the same time, when the first vibration block 12 rotates, the first driving block 13 rotates, and through the teeth 11, the sieve mesh 3 is pushed to the left along the vibration frame 4. And under the rotation of the second driving block 15, the second driving block 15 will reset the sieve mesh 3 to the right through the teeth 11 at the bottom of the moving block 9, completing a single left-and-right screening. During screening, the impurities between the agricultural products will vibrate up and down and left and right, screening stubborn impurities into the interior of the fixed table 1 and falling onto the top of the guide plate 22. Then, the staff start the negative pressure fan 24. The negative pressure environment provided by the negative pressure fan 24 causes the negative pressure fan 24 to suck the impurities on the top of the guide plate 22 into the interior of the collection box 23 through the dust collection pipe 26, completing the collection of impurities.

[0032] Through the operation of the motor 18, the first vibration block 12 and the second vibration block 14 rotate in opposite directions simultaneously, jolting the sieve mesh 3 up and down. At the same time, when the first vibration block 12 rotates, the first driving block 13 rotates, and through the moving block 9, the sieve mesh 3 is pushed to the left along the vibration frame 4. And under the rotation of the second driving block 15, the second driving block 15 will reset the sieve mesh 3 to the right through the moving block 9 at the bottom of the sieve mesh 3, completing a single left-and-right screening. Compared with traditional devices, this device makes the movement of materials on the sieve mesh more complex and sufficient through a multi-dimensional vibration method, which helps to further improve the impurity removal effect. And the up-and-down and left-and-right vibration impurity removal is applicable to a wider range of materials, including materials with poor fluidity and high viscosity. Through multi-dimensional vibration, the separation of impurities and materials can be better achieved.

[0033] Among them, a collection box 23 is fixedly installed on the left side of the fixed table 1. A negative pressure fan 24 is fixedly installed on the top of the collection box 23. The negative pressure fan 24 is fixedly connected to the dust collection pipe 26. A guide plate 22 is fixedly installed inside the fixed table 1. A collection port 25 is fixedly installed on the left side of the fixed table 1. One end of the dust collection pipe 26 communicates with the collection port 25.

[0034] During screening, impurities between agricultural products will shake up and down and left and right, so that stubborn impurities are screened into the inside of the fixed table 1 and fall into the top of the guide plate 22. Then the staff starts the negative pressure fan 24. The negative pressure environment provided by the negative pressure fan 24 causes the negative pressure fan 24 to suck the impurities on the top of the guide plate 22 into the collection box 23 through the dust collecting pipe 26, thereby completing the collection of impurities.

[0035] Through the negative pressure environment provided by the negative pressure fan 24, the negative pressure fan 24 can suck the impurities on the top of the guide plate 22 into the interior of the collection box 23 through the dust collecting pipe 26, thereby completing the collection of impurities. Compared with the traditional device, the device can suck the screened impurities into the interior of the collection box 23 through the negative pressure fan 24 under negative pressure, preventing dust generated by dry soil blocks during screening, ensuring the working environment of the staff, and reducing safety hazards.

[0036] The guide rods 7 are fixedly installed inside the four groups of limiting grooves 6 , and one end of the sliding block 5 and the inner wall of the limiting groove 6 are elastically connected via a return spring 8 .

[0037] Among them, a driving wheel 17 is rotatably installed on the rear side wall of the fixed platform 1, and one end of the driving wheel 17 is fixedly connected to the vibration block 12. A driving wheel 20 is rotatably installed on the rear side wall of the fixed platform 1, and one end of the driving wheel 20 is fixedly connected to the vibration block 2 14. A motor 18 is fixedly installed on the rear wall of the fixed platform 1, and the output shaft of the motor 18 is fixedly connected to the driving wheel 17.

[0038] The staff starts the motor 18, and the operation of the motor 18 drives the driving wheel 17 to rotate. The driving wheel 17 and the transmission wheel 19 are meshed with each other, and the transmission wheel 19 and the driving wheel 2 20 are connected by the transmission belt 21, so that the driving wheel 2 20 rotates, and at this time, the rotation directions of the driving wheel 17 and the driving wheel 2 20 are opposite.

[0039] A transmission wheel 19 is rotatably mounted on the rear wall of the fixed platform 1 . The transmission wheel 19 and the driving wheel 1 17 are meshed with each other. The transmission wheel 19 and the driving wheel 2 20 are connected through a transmission belt 21 .

[0040] The vibration block 1 12 and the vibration block 2 14 are located at the left and right sides of the bottom of the vibration frame 4 , and the tops of the vibration block 2 14 and the vibration block 1 12 and the bottom of the vibration frame 4 abut against each other.

[0041] The driving block 1 13 and the moving block 9 are meshed with each other, and the driving block 13 and the driving block 2 15 are at 90 degrees.

[0042] The drive block 13 rotates, and through the teeth 11 at the bottom of the moving block 9, the sieve 3 is pushed leftward along the vibration frame 4. Under the rotation of the drive block 2, the drive block 2 will reset the sieve 3 to the right through the moving block 9 at the bottom of the sieve 3, completing a single left-right screening.

[0043] The working principle and usage process of the present utility model:

[0044] When impurity screening operation is required, the staff adds agricultural products on the top of the sieve 3 through the feeding plate 2. Then the staff starts the motor 18. The operation of the motor 18 drives the rotation of the first drive wheel 17. The first drive wheel 17 and the transmission wheel 19 are meshed with each other, and the transmission wheel 19 and the second drive wheel 20 are connected by a transmission belt 21 for transmission, so that the second drive wheel 20 rotates. At this time, the rotation directions of the first drive wheel 17 and the second drive wheel 20 are opposite. When the first drive wheel 17 and the second drive wheel 20 rotate one week, the first vibration block 12 and the second vibration block 14 rotate, lifting the vibration frame 4. And through the elastic potential energy of the return spring 8, after the vibration frame 4 is lifted, the slider 5 resets downward along the return spring 8, completing a single up-down vibration. At the same time, when the first vibration block 12 rotates, the drive block 13 rotates, and through the teeth 11, the sieve 3 is pushed leftward along the vibration frame 4. Under the rotation of the drive block 2, the drive block 2 will reset the sieve 3 to the right through the teeth 11 at the bottom of the moving block 9, completing a single left-right screening. During screening, the impurities between the agricultural products will vibrate up and down and left and right, screening the stubborn impurities into the interior of the fixed table 1 and falling onto the top of the guide plate 22. Then the staff starts the negative pressure fan 24. The negative pressure environment provided by the negative pressure fan 24 enables the negative pressure fan 24 to suck the impurities on the top of the guide plate 22 into the interior of the collection box 23 through the dust collection pipe 26, completing the collection of impurities.
