Abstract
Description
Technical Field
[0001] This utility model belongs to the field of grain processing technology, and in particular relates to a feeding control device for grain processing. Background Technology
[0002] Grains mainly include cereal crops (such as rice, wheat, and corn) and legume crops (such as soybeans, mung beans, and red beans). These crops provide humans with abundant nutrition and energy, and are an important material basis for maintaining life activities.
[0003] For example, Chinese patent CN210192383U discloses a feeding control device for grain processing. Its key technical features include a feeding box and processing equipment. A control component is installed inside the feeding box, comprising a mounting cylinder and adjusting plates. Multiple adjusting plates can close the mounting cylinder; when closed, the plates abut each other to form a rectangle. A fixed shaft, fixedly connected to the adjusting plate, passes through each plate. Each fixed shaft exits from the same side of the mounting cylinder, and a linkage component is located at the end of the fixed shaft exiting the mounting cylinder. One of the fixed shafts is a drive shaft, with both ends extending out of the mounting cylinder. A servo motor for driving the drive shaft is located on the outer side of the mounting cylinder away from the linkage component. A control switch for controlling the servo motor's opening and closing is located on the outer wall of the feeding box, and the control switch is electrically connected to the servo motor. This device can adjust the amount of grain fed, thereby improving grain processing efficiency.
[0004] The aforementioned patent has the following problems:
[0005] The patented device has several drawbacks in its use. For example, when workers pour grain into the device, the falling grain generates dust. If this dust is released directly into the environment without treatment, workers may inhale it, potentially harming their health. Furthermore, the grain may contain stones; if these stones enter the feeding control device directly, they will be carried to the next processing step, ultimately affecting the grain's edibility and safety. Therefore, we propose a feeding control device for grain processing. Utility Model Content
[0006] The purpose of this invention is to provide a feeding control device for grain processing to solve the problems mentioned in the background art.
[0007] In view of this, the present invention provides a feeding control device for grain processing, comprising:
[0008] The housing has a sliding groove inside, a sliding frame is slidably installed in the sliding groove, a stainless steel filter screen is fixedly installed in the sliding frame, a rotating disk is rotatably installed in the sliding groove on both sides of the sliding frame, the two rotating disks are coaxially connected, and the tops of the two rotating disks are in contact with the sliding frame. An auger is rotatably installed in the housing below the sliding frame.
[0009] A drive assembly, located within the housing, is used to drive one of the rotating disks and the auger to rotate;
[0010] A fixed frame is fixedly installed inside the housing and above the first sliding frame. A second stainless steel filter screen is fixedly installed inside the fixed frame. A second sliding frame is fixedly installed inside the housing and on one side of the fixed frame. An activated carbon filter screen is fixedly installed inside the second sliding frame. A third sliding frame is fixedly installed inside the housing and on one side of the second sliding frame. A HEPA filter screen is fixedly installed inside the third sliding frame. Two negative pressure fans are fixedly installed inside the housing and on one side of the third sliding frame.
[0011] A fixing component is located inside the housing and is used to fix the positions of sliding frame two and sliding frame three.
[0012] In this technical solution, when grain needs to be fed, the worker first pours the grain continuously into the shell. The grain then falls to the top of the stainless steel filter screen one. At the same time, two negative pressure fans are activated. The two negative pressure fans will draw the dust generated by the falling grain through the stainless steel filter screen two and onto the activated carbon filter screen. The stainless steel filter screen two will intercept the grain, ensuring that all the grain enters the top of the stainless steel filter screen one. Then the dust enters the activated carbon filter screen, which can adsorb large dust particles. The dust then enters the HEPA filter screen, which adsorbs small dust particles. Finally, the dust-free air is discharged to the outside through the two negative pressure fans, ensuring that the dust will not affect the working environment.
[0013] The power unit can drive one of the rotating discs to rotate, and the rotating disc drives the other rotating disc to rotate. After the two rotating discs rotate 90°, the sliding frame will slide downward under the action of gravity, which can screen the grain and ensure that the grain can fall through the stainless steel filter screen onto the auger. The stones in the grain will stay on the top of the stainless steel filter screen. The power unit can drive the auger to rotate and transport the grain to the discharge port of the shell for discharge. The power unit can control the discharge speed and filter the stones in the grain to ensure that the grain is free of stones.
[0014] When it is necessary to replace the activated carbon filter and HEPA filter, the staff can pull up sliding frame two and sliding frame three respectively through the fixed components to remove them, making it convenient for the staff to clean the activated carbon filter and HEPA filter and ensure that the activated carbon filter and HEPA filter will not be clogged during use. By reversing the above operation, sliding frame two and sliding frame three can be fixed into the housing, making the operation convenient and quick.
[0015] In the above technical solution, the driving component further includes:
[0016] The motor is fixedly mounted on the housing and located at one end of the auger. The output shaft of the motor passes through the housing and is fixedly connected to the auger. A second transmission wheel is fixedly mounted on the output shaft of the motor. One end of one of the rotating disks extends through a sliding groove to the outside and is fixedly mounted with a first transmission wheel. The first transmission wheel is located above the second transmission wheel, and a transmission belt is installed between the first transmission wheel and the second transmission wheel.
[0017] In this technical solution, the motor is started, and the motor is powered on and drives the second transmission wheel and the auger to rotate. The second transmission wheel drives the transmission belt, which drives the first transmission wheel to rotate. The first transmission wheel drives one of the rotating disks to rotate, and the first rotating disk drives the other rotating disk to rotate. After the two rotating disks rotate 90°, the sliding frame 1 will slide downward under the action of gravity, which can screen the grain and ensure that the grain can fall onto the auger through the stainless steel filter screen 1. The stones in the grain will stay on the top of the stainless steel filter screen 1. At the same time, the rotation of the auger can transport the grain to the discharge port of the shell for discharge. By controlling the speed of the motor, the discharge speed can be controlled, and the stones in the grain can be filtered to ensure that the grain is free of stones.
[0018] In the above technical solution, the fixing component further includes:
[0019] A limiting groove is formed inside the housing and located between sliding frame two and sliding frame three. A sliding plate is slidably installed in the limiting groove. The upper end of the sliding plate passes through the limiting groove and extends to the outside. Several tension springs fixed to the inner wall of the limiting groove are fixedly installed on one side of the sliding plate. Two guide grooves are formed at the bottom of the sliding plate. Guide posts are slidably installed in both guide grooves. Limiting strips are fixedly installed at the lower ends of both guide posts. The ends of the two limiting strips that are far apart from each other extend into sliding frame two and sliding frame three, respectively, and the ends of the two limiting strips that are far apart from each other are respectively inserted into sliding frame two and sliding frame three. Both limiting strips are slidably connected to the limiting groove.
[0020] In this technical solution, when it is necessary to replace the activated carbon filter and the HEPA filter, first pull the sliding plate away from the tension spring. At the same time, several tension springs are stretched. Then, the sliding plate drives the two guide posts to slide and move closer to each other through the two guide grooves. The two guide posts pull the two limiting strips to slide and move closer to each other. When the ends of the two limiting strips that are far apart from each other are disengaged from the sliding frame two and sliding frame three respectively, the operator can pull the sliding frame two and sliding frame three upwards to remove them. This makes it convenient for the operator to clean the activated carbon filter and the HEPA filter, ensuring that the activated carbon filter and the HEPA filter will not be clogged during use. By performing the above reverse operation, the sliding frame two and sliding frame three can be fixed into the housing. The operation is convenient and quick.
[0021] In the above technical solution, the output shaft of the motor is rotatably connected to the housing.
[0022] In this technical solution, it is ensured that the output shaft of the motor can rotate within the housing.
[0023] Furthermore, in the above technical solution, handles are fixedly installed on the top of both the second and third sliding frames.
[0024] In this technical solution, the handles make it easy for staff to pull the sliding frame two and the sliding frame three.
[0025] In the above technical solution, the filtration accuracy of the HEPA filter is greater than that of the activated carbon filter, the filtration accuracy of the activated carbon filter is greater than that of the stainless steel filter, and the filtration accuracy of the stainless steel filter is greater than that of the stainless steel filter.
[0026] In this technical solution, the stainless steel filter screen 2 is designed to intercept the grain, ensuring that all the grain enters the top of the stainless steel filter screen 1. Subsequently, the dust enters the activated carbon filter screen, which adsorbs large dust particles. Then, the dust enters the HEPA filter screen, which adsorbs small dust particles.
[0027] In the above technical solution, the cross-section of the rotating disk is elliptical.
[0028] In this technical solution, after the two rotating disks rotate 90°, the sliding frame slides downward under the action of gravity, which can screen the grain.
[0029] The beneficial effects of this utility model are:
[0030] 1. This feeding control device for grain processing involves the following steps: When grain needs to be fed, the worker first pours the grain continuously into the housing. The grain then falls to the top of the stainless steel filter screen one. Simultaneously, two negative pressure fans are activated. These fans draw the dust generated by the falling grain through the stainless steel filter screen two and onto the activated carbon filter screen. The stainless steel filter screen two intercepts the grain, ensuring that all the grain enters the top of the stainless steel filter screen one. Subsequently, the dust enters the activated carbon filter screen, which adsorbs large dust particles. Then, the dust enters the HEPA filter screen, which adsorbs small dust particles. Finally, the dust-free air is discharged to the outside through the two negative pressure fans, ensuring that dust does not affect the working environment.
[0031] 2. This feeding control device for grain processing, through a power component, can drive one of the rotating discs to rotate, and one of the rotating discs drives the other rotating disc to rotate. After the two rotating discs rotate 90°, under the action of gravity, the sliding frame will slide downwards, which can screen the grain and ensure that the grain can fall through the stainless steel filter screen onto the auger. The stones in the grain will stay on the top of the stainless steel filter screen. The power component can drive the auger to rotate, which can transport the grain to the discharge port of the shell for discharge. The power component can control the discharge speed and filter the stones in the grain to ensure that the grain is free of stones.
[0032] 3. This feeding control device for grain processing allows operators to easily remove the activated carbon filter and HEPA filter by pulling sliding frames two and three upwards using the fixed components. This facilitates cleaning of the activated carbon filter and HEPA filter, ensuring that they do not become clogged during use. The reverse operation fixes sliding frames two and three back into the housing, making the operation convenient and quick. Attached Figure Description

[0048] Example 1:
[0049] Please see Figure 1 - Figure 8 As shown, this embodiment provides a feeding control device for grain processing, including:
[0050] The housing 1 has a sliding groove 2 inside, a sliding frame 3 is slidably installed in the sliding groove 2, a stainless steel filter screen 4 is fixedly installed in the sliding frame 3, a rotating disk 5 is rotatably installed in the sliding groove 2 on both sides of the sliding frame 3, the two rotating disks 5 are coaxially connected, and the tops of the two rotating disks 5 are in contact with the sliding frame 3. An auger 6 is rotatably installed in the housing 1 below the sliding frame 3.
[0051] A drive assembly is located inside the housing 1 and is used to drive one of the rotating disks 5 and the auger 6 to rotate.
[0052] A fixed frame 7 is fixedly installed inside the housing 1 and above the sliding frame 3. A stainless steel filter screen 8 is fixedly installed inside the fixed frame 7. A sliding frame 9 is fixedly installed inside the housing 1 and on one side of the fixed frame 7. An activated carbon filter screen 10 is fixedly installed inside the sliding frame 9. A sliding frame 11 is fixedly installed inside the housing 1 and on one side of the sliding frame 9. A HEPA filter screen 12 is fixedly installed inside the sliding frame 11. Two negative pressure fans 13 are fixedly installed inside the housing 1 and on one side of the sliding frame 11.
[0053] A fixing component is located inside the housing 1 and is used to fix the positions of sliding frame 2 9 and sliding frame 3 11.
[0054] When feeding grain, the staff first pours the grain continuously into the housing 1. The grain then falls to the top of the stainless steel filter screen 4. At the same time, two negative pressure fans 13 are activated. The two negative pressure fans 13 will suck the dust generated by the falling grain through the stainless steel filter screen 28 to the activated carbon filter screen 10. The stainless steel filter screen 28 will intercept the grain, ensuring that all the grain enters the top of the stainless steel filter screen 4. Then the dust enters the activated carbon filter screen 10, which can adsorb the large dust particles. The dust then enters the HEPA filter screen 12, which adsorbs the small dust particles. Finally, the dust-free air is discharged to the outside through the two negative pressure fans 13, ensuring that the dust will not affect the working environment.
[0055] The power assembly can drive one of the rotating disks 5 to rotate, and the rotating disk 5 drives the other rotating disk 5 to rotate. After the two rotating disks 5 rotate 90°, the sliding frame 3 will slide downward under the action of gravity, which can screen the grain and ensure that the grain can fall through the stainless steel filter screen 4 onto the auger 6. The stones in the grain will stay on the top of the stainless steel filter screen 4. The power assembly can drive the auger 6 to rotate and transport the grain to the discharge port of the shell 1 for discharge. The power assembly can control the discharge speed and filter the stones in the grain to ensure that the grain is free of stones.
[0056] When it is necessary to replace the activated carbon filter 10 and the HEPA filter 12, the operator can pull the sliding frame 2 9 and the sliding frame 3 11 upwards respectively through the fixed components to facilitate cleaning of the activated carbon filter 10 and the HEPA filter 12, ensuring that the activated carbon filter 10 and the HEPA filter 12 will not be clogged during use. The sliding frame 2 9 and the sliding frame 3 11 can be fixed into the housing 1 by the above reverse operation, which is convenient and quick.

A second transmission wheel 24 is fixedly mounted on the output shaft of motor 20. One end of a rotating disk 5 extends through sliding groove 2 to the outside and is fixedly mounted with a first transmission wheel 21. The first transmission wheel 21 is located above the second transmission wheel 24, and a transmission belt 22 is installed between the first transmission wheel 21 and the second transmission wheel 24.
[0059] The motor 20 is started and powered on, driving the transmission wheel 24 and the auger 6 to rotate. The transmission wheel 24 drives the transmission belt 22, which in turn drives the transmission wheel 21 to rotate. The transmission wheel 21 drives one of the rotating disks 5 to rotate, and the rotating disk 5 drives the other rotating disk 5 to rotate. After the two rotating disks 5 rotate 90°, the sliding frame 3 will slide downward under the action of gravity, which can screen the grain and ensure that the grain can fall through the stainless steel filter screen 4 onto the auger 6. The stones in the grain will stay on the top of the stainless steel filter screen 4. At the same time, the rotation of the auger 6 can transport the grain to the discharge port of the shell 1 for discharge. By controlling the speed of the motor 20, the discharge speed can be controlled, and the stones in the grain can be filtered to ensure that the grain is free of stones.
[0060] In this embodiment, the fixing component includes:
[0061] A limiting groove 14 is formed inside the housing 1 and located between sliding frame 2 9 and sliding frame 3 11. A sliding plate 15 is slidably installed in the limiting groove 14.

Two guide grooves 17 are formed at the bottom of the sliding plate 15. Guide posts 18 are slidably installed in both guide grooves 17. Limiting strips 19 are fixedly installed at the lower ends of both guide posts 18. The ends of the two limiting strips 19 that are far apart from each other extend into sliding frame 2 9 and sliding frame 3 11 respectively. The ends of the two limiting strips 19 that are far apart from each other are respectively inserted into sliding frame 2 9 and sliding frame 3 11. Both limiting strips 19 are slidably connected to the limiting groove 14.
[0062] When it is necessary to replace the activated carbon filter 10 and the HEPA filter 12, first pull the sliding plate 15 away from the tension spring 16. At the same time, several tension springs 16 are stretched. Then, the sliding plate 15 drives the two guide posts 18 to slide and move closer to each other through the two guide grooves 17. The two guide posts 18 pull the two limiting strips 19 to slide and move closer to each other. When the ends of the two limiting strips 19 that are far apart from each other are disengaged from the sliding frame 2 9 and the sliding frame 3 11 respectively, the staff can pull the sliding frame 2 9 and the sliding frame 3 11 upwards to remove them. This makes it convenient for the staff to clean the activated carbon filter 10 and the HEPA filter 12, ensuring that the activated carbon filter 10 and the HEPA filter 12 will not be blocked during use. By performing the above reverse operation, the sliding frame 2 9 and the sliding frame 3 11 can be fixed into the housing 1. The operation is convenient and quick.
