[0002] Red ginseng is an important variety of commercial ginseng. There are many types of red ginseng. Red ginseng is a cooked ginseng. Long-term consumption of red ginseng can improve human immunity, resist fatigue, resist radiation, inhibit tumors, and adjust the human endocrine system. Red ginseng has the characteristics of being hot, strong, and effective. It is the first choice tonic for those with yin excess and yang deficiency. Red ginseng is often used in medical treatment of collapse or tonic. In the deep processing of red ginseng, a crushing and screening device is needed to crush and screen the dried raw materials.

[0003] For example, the patent with publication number CN219647681U discloses a ginseng crushing device with filtering function. This patent uses the vibrator in the filtering component to vibrate, so that the ginseng material falling on the filter screen is screened by the filter screen, so as to avoid the ginseng material that does not meet the particle size requirements being mixed in the material that meets the requirements, improve the quality of ginseng powder, and make the ginseng material that does not meet the particle size requirements be discharged through the discharge channel, and the material that meets the requirements falls into the bottom of the crushing box through the filter screen and is discharged through the discharge pipe. However, in the actual use of this type of equipment, it is still necessary to manually transfer the ginseng material that does not meet the particle size requirements to the inside of the equipment for re-crushing, which results in the problem of being time-consuming and labor-intensive when using it.

[0014] A red ginseng deep processing device is provided, wherein the red ginseng deep processing device is equipped with the crushing and screening device as described above.

[0015] A red ginseng deep processing method, applied to the crushing and screening device, comprises the following steps:

[0016] S1: Start the double-output shaft reduction motor to make the two crushing rollers work through the driving gear, the double gear and the driven gear, and then add the material into the shell to crush the material, and the crushed material can fall onto the screen plate;

[0017] S2: The crushing roller will also drive the driving rod to rotate, and when the driving rod contacts the driving wheel, it will squeeze the driving wheel, so that it drives the screen plate to move through the connecting plate and the sliding rod. As the crushing roller continues to rotate, the driving rod will separate from the driving wheel, and the vibration spring will recover from the compressed state, at which time it can drive the screen plate to vibrate back and forth to screen the material;

[0018] S3: When the crushing roller drives the cam to squeeze the pulley seat, the lifting seat will move downward, and the first baffle will be driven to block the material above the screen plate. When the convex part of the cam is separated from the pulley seat, the tension spring will pull the lifting seat under the limit of the connecting ear, and the first baffle will be driven to move upward. At this time, the transposition plate will rotate around the rotating shaft, so that the second baffle moves downward under the limit of the side plate. Therefore, the first baffle and the second baffle are used to intermittently block the material during screening, thereby extending the residence time of the material on the screen plate.

[0019] S4: The material passing through the sieve plate can be discharged from the discharge port at the bottom of the shell, and the material blocked by the sieve plate will fall from the return frame to the lower end of the conveying pipe. At this time, the double-output shaft reduction motor will also drive the sprocket to rotate, so that the chain drives the scraper to circulate and move continuously in the conveying pipe, so that the scraper can push the material to the upper part of the conveying pipe, and the material will fall from the discharge frame to the top surface of the guide plate;

[0020] S5: When the sprocket rotates, it will push and pull the piston rod back and forth through the connecting rod. When the piston rod is pushed, the air inside the cylinder can enter the shunt pipe through the second one-way valve at one end of the top, and blow to the scraper from the nozzle at the top. In this process, the external air can be replenished into the cylinder from the first one-way valve at the other end of the bottom of the cylinder. When the piston rod is pulled, the other set of the first one-way valve and the second one-way valve will repeat the above work.

[0021] S6: During the blowing process, the airflow will also blow to the guide plate, causing the guide plate to be subjected to force. When the scraper covers the nozzle, the force on the guide plate will change. Therefore, the guide plate can be vibrated under the action of the supporting spring, so that when the material falls on the guide plate, it can be vibrated to the crushing roller.

[0022] The present invention provides a crushing and screening device and a red ginseng deep processing device and a processing method, which have the following beneficial effects:

[0023] 1. When the double-output shaft reduction motor of the present invention enables the two crushing rollers to crush the material through the driving gear, the double gear and the driven gear, it can also drive the sprocket to rotate at the same time, and the sprocket is meshed with the chain, so that the chain drives the scraper to circulate and move continuously in the conveying pipe. Therefore, when the material particles that do not meet the particle size requirements are blocked by the screen plate, they will fall from the return frame to the lower end of the conveying pipe. At this time, the scraper can push the material to move inside the conveying pipe, and when the material is located at the upper part of the conveying pipe, the material will be re-added to the top of the crushing roller from the discharge frame under the action of gravity. Therefore, in the process of crushing the material, the uncrushed and incomplete material can be automatically crushed again without manual transfer, which makes the operation labor-saving and convenient.

[0024] 2. During the operation of the crushing roller, the present invention will also drive the driving rod to rotate, and when the driving rod contacts the driving wheel, it will squeeze the driving wheel, so that it drives the screen plate to move through the connecting plate and the sliding rod. At this time, the vibration spring close to the connecting plate will be compressed, and as the crushing roller continues to rotate, the driving rod is separated from the driving wheel, and the vibration spring will recover from the compressed state, and then the screen plate can be driven to move back, and the elasticity of the vibration spring is used to amplify the vibration. Therefore, during use, the screen plate can be vibrated back and forth without adding an additional power source, so as to screen the material, thereby saving the use cost, and the side plates can cover both sides of the screen plate to prevent the material from passing through both sides of the screen plate.

[0025] 3. The tension spring of the present invention will pull the lifting seat under the limit of the connecting ear, so that the pulley seat and the cam are in close contact. Therefore, when the crushing roller drives the cam to rotate, the lifting seat will move up and down reciprocatingly, and when the lifting seat moves up, it will drive the first baffle to move up. At this time, the transposition plate will rotate around the rotating shaft, so that the second baffle moves down under the limit of the side plate, and when the first baffle moves down, the second baffle can be moved up by the transposition plate. Therefore, during the screening process, the first baffle and the second baffle can be used to intermittently block the material, thereby extending the residence time of the material on the screen plate, avoiding the material from sliding too fast and falling into the return frame without being completely screened, thereby improving the overall screening effect.

[0026] 4. In the process of sprocket rotation, the present invention will push and pull the piston rod back and forth through the connecting rod, and when the piston rod is pushed, the air inside the cylinder can enter the diverter pipe through the second one-way valve at one end of the top, and blow to the scraper from the nozzle at the end, thereby preventing the material from adhering to the scraper and affecting the effect of material stripping. In this process, external air can be replenished into the cylinder from the first one-way valve at the other end of the bottom of the cylinder, and when the piston rod is pulled, the other group of the first one-way valve and the second one-way valve will repeat the above work, so that jet cleaning can be performed during the reciprocating movement of the piston rod, thereby improving the effect of material stripping. At the same time, the airflow will also blow to the guide plate, so that the guide plate is subjected to force, and when the scraper blocks the nozzle, the force on the guide plate will change, so that the guide plate can be vibrated under the action of the support spring, so that when the material falls on the guide plate, the material can be vibrated to the crushing roller to avoid the situation of material accumulation.

Secondly, the crushed material can fall onto the screen plate 406. At this time, the side plate 407 can block the two sides of the screen plate 406 to prevent the material from passing through the two sides of the screen plate 406. At the same time, the crushing roller 304 will also drive the driving rod 401 to rotate, and when the driving rod 401 contacts the driving wheel 405, it will squeeze the driving wheel 405, so that it drives the screen plate 406 through the connecting plate 404 and the sliding rod 402. 6 moves, and as the crushing roller 304 continues to rotate, the driving rod 401 will separate from the driving wheel 405, and the vibration spring 403 will recover from the compressed state, and at this time, the screen plate 406 can be driven to vibrate back and forth to screen the materials.

At this time, the transposition plate 507 will rotate around the rotating shaft 508, so that the second baffle plate 50 9 moves downward under the limit of the side plate 407. Therefore, during the screening process, the first baffle plate 506 and the second baffle plate 509 can be used to intermittently block the material, thereby extending the residence time of the material on the screen plate 406. Then, the material passing through the screen plate 406 can be discharged from the discharge port below the shell 1, and the material blocked by the screen plate 406 will fall from the return frame 605 to the lower end of the conveying pipe 604.

Therefore, under the action of the support spring 708, the guide plate 709 can be vibrated, so that when the material falls on the guide plate 709, the material can be vibrated to the crushing roller 304 to avoid material accumulation.External air can be replenished into the air cylinder 703 from the first one-way valve 704 at the other end of the bottom of the air cylinder 703, and when the piston rod 702 is pulled, the other set of the first one-way valve 704 and the second one-way valve 705 will repeat the above work.

8. A red ginseng deep processing device, characterized in that: The red ginseng deep processing device is equipped with the crushing and screening device as claimed in claim 7.

9. A red ginseng deep processing method, characterized in that: The red ginseng deep processing device as claimed in claim 8 comprises the following steps: S1: Start the double-output shaft reduction motor (2) to make the two crushing rollers (304) work through the driving gear (301), the double gear (302), and the driven gear (303), and then add the material into the housing (1) to crush the material, and the crushed material can fall onto the screen plate (406); S2: The crushing roller (304) also drives the driving rod (401) to rotate, and when the driving rod (401) contacts the driving wheel (405), it squeezes the driving wheel (405), so that the sieve plate (406) moves through the connecting plate (404) and the sliding rod (402), and as the crushing roller (304) continues to rotate, the driving rod (401) separates from the driving wheel (405), and the vibration spring (403) recovers from the compressed state, and at this time, it can drive the sieve plate (406) to vibrate back and forth to screen the material; S3: When the crushing roller (304) drives the cam (501) to squeeze the pulley seat (502), the lifting seat (503) will move downward, and at this time, the first baffle (506) will be driven to block the material above the screen plate (406). When the convex part of the cam (501) is separated from the pulley seat (502), the tension spring (504) will pull the lifting seat (503) under the limit of the connecting ear (505), and the first baffle (506) will be driven to move upward. At this time, the transposition plate (507) will rotate around the rotating shaft (508) as the center, so that the second baffle (509) moves downward under the limit of the side plate (407). Therefore, during screening, the first baffle (506) and the second baffle (509) are used to intermittently block the material, thereby extending the residence time of the material on the screen plate (406); S4: The material that has passed through the sieve plate (406) can be discharged from the discharge port below the housing (1), while the material that has been blocked by the sieve plate (406) will fall from the return frame (605) to the lower end of the conveying pipe (604). At this time, the double-shaft reduction motor (2) will also drive the sprocket (601) to rotate, so that the chain (602) drives the scraper (603) to circulate and move continuously in the conveying pipe (604), so that the scraper (603) can push the material to the upper part of the conveying pipe (604), and the material will fall from the discharge frame (606) to the top surface of the guide plate (709); S5: When the sprocket wheel (601) rotates, it pushes and pulls the piston rod (702) back and forth through the connecting rod (701). When the piston rod (702) is pushed, the air inside the air cylinder (703) can enter the diverter pipe (706) through the second one-way valve (705) at one end of the top, and blow toward the scraper (603) from the nozzle at the top. During this process, the external air can be replenished into the air cylinder (703) from the first one-way valve (704) at the other end of the bottom of the air cylinder (703). When the piston rod (702) is pulled, the other set of the first one-way valve (704) and the second one-way valve (705) will repeat the above operation. S6: During the blowing process, the airflow will also blow toward the guide plate (709), causing the guide plate (709) to be subjected to force. When the scraper (603) blocks the nozzle, the force applied to the guide plate (709) will change. Therefore, the guide plate (709) can be vibrated under the action of the support spring (708), so that when the material falls onto the guide plate (709), the material can be vibrated and dropped to the crushing roller (304).
