Description

Technical Field

[0001] The present invention relates to the field of tea essence preparation, and specifically to a crusher and a crushing method for preparing natural tea essence. Background Art

[0002] Tea therapy has a long history in China. In "Supplements to Materia Medica" by Chen Cangqi, a pharmacologist in the Tang Dynasty, it is mentioned that "all medicines are for various diseases, and tea is for all diseases", indicating that tea has the efficacy of preventing and treating diseases. Modern science has proved that there are more than 500 chemical components in tea, mainly including catechins, tea polyphenols, theophylline, flavonoids, etc. These components have unique effects on preventing and treating cancer, cardiovascular diseases, diabetes, etc., and at the same time have the effects of promoting the production of body fluid and relieving cough, anti-aging, anti-radiation, etc. In recent years, tea foods, especially tea beverages, have developed rapidly, and the additive tea essence used therein has also emerged accordingly.

[0003] When preparing natural tea essence, it is first necessary to use a crusher to crush the tea leaves to form tea powder. However, when the existing crushers are crushing, they crush the tea leaves as a whole. During the tea processing process, the aroma substances in the tea stalks will transfer to the leaf buds, resulting in very little aroma in the tea stalks. If the leaf buds and tea stalks are crushed as a whole, the effective content in the tea powder will be low, which will not only affect the efficiency of preparing natural tea essence, but also cause waste of enzymes in the subsequent enzymatic hydrolysis process, and affect the purity and quality.

[0015] A crushing method for preparing natural tea essence includes the following steps:

[0016] S1: Place the tea leaves on the conveyor belt for conveyance. Meanwhile, start the motor. The rotation of the motor drives the rotation of the first threaded rod, which in turn drives the fourth moving plate to move downward. When the fourth moving plate moves downward, it drives the third connecting plate to move downward synchronously, causing the convex strips to successively abut against and slide along the side wall of the conveyor belt, thereby forming a vibration effect on the conveyor belt, and thus flattening the tea leaves on the conveyor belt to avoid stacking.

[0017] S2: When the fourth moving plate moves downward, it drives the first moving plate, the second moving plate, and the third moving plate to move downward synchronously. Meanwhile, the sliding pin slides downward along the vertical section. When the rolling block abuts against the leaf buds or tea stalks of the tea leaves and, under the action of the pressure regulating mechanism, crushes the leaf buds, while the tea stalks will not be crushed.

[0018] S3: When the sliding pin slides to the bottom of the vertical section, under the action of the first spring, the sliding pin slides along the horizontal section. At this time, the first moving plate and the second moving plate on each group of moving plate groups move away from each other, so that the rolling block can crush the leaf buds, and, under the action of the rolling block, the tea stalks can be rotated to turn the tea leaves over, so that the crushing is more complete and the effect is better.

[0019] S4: Reverse the motor to drive the fourth moving plate, the first moving plate, and the second moving plate to move upward. At the same time, the sliding pin slides upward along the inclined section, so that the first moving plate, the second moving plate, and the third moving plate move back to their original positions, causing the rolling block to be briefly separated from the tea leaves. Repeating this process, the first moving plate and the second moving plate can reciprocate. At the same time, the first moving plate and the second moving plate are staggered and move in opposite directions. Under the conveying action of the conveyor belt, it can prevent the rolling block from shifting the tea leaves to one side, enabling the rolling block to intermittently and reciprocally rub and crush the leaf buds. At the same time, it can prevent the rolling block from continuously rubbing the tea stalks and avoid breaking the tea stalks.

[0020] S5: During crushing, start the exhaust fan to draw air through the connecting pipe. At the same time, when the fourth moving plate moves upward, the convex strips will also form a vibration effect on the conveyor belt, causing the leaf bud powder intermittently and reciprocally rubbed and crushed by the rolling block to enter the collection cover through the filter holes, and be sucked through the connecting pipe and sent into the filter box for collection. Under the filtering action of the filter plate, the leaf bud powder falls into the collection box for collection, while the unbroken tea stalks continue to be conveyed by the conveyor belt and fall into the collection box for collection, thus facilitating the classified collection of leaf bud powder and tea stalks.

[0021] Advantages of the present invention:

[0022] (1) A crusher and crushing method for preparing natural tea essence according to the present invention, by setting a vibration mechanism, etc. When it is necessary to crush tea leaves, the tea leaves are placed on the conveyor belt for transportation. At the same time, the motor is started, and the rotation of the motor drives the rotation of the first threaded rod, which in turn drives the fourth moving plate to move downward. When the fourth moving plate moves downward, it drives the third connecting plate to move downward synchronously, so that the convex strips successively abut and slide against the side wall of the conveyor belt, thereby forming a vibration effect on the conveyor belt, which facilitates the flattening of the tea leaves on the conveyor belt, avoids stacking, and thus makes the subsequent crushing effect better. Moreover, after the crushing is completed, when the fourth moving plate moves upward, the convex strips will also form a vibration effect on the conveyor belt, which facilitates the collection of the tea leaf powder on the conveyor belt.

[0023] (2) A crusher and crushing method for preparing natural tea essence according to the present invention, by setting a grinding mechanism, etc. When the fourth moving plate moves downward, it drives the first moving plate, the second moving plate and the third moving plate to move downward synchronously. At the same time, the sliding pin slides downward along the vertical section. When the rolling block abuts against the leaf bud or tea stalk of the tea leaf and, under the action of the pressure regulating mechanism, crushes the leaf bud, while the tea stalk will not be crushed. When the sliding pin slides to the bottom of the vertical section, under the action of the first spring, the sliding pin slides along the horizontal section. At this time, the first moving plate and the second moving plate on each group of moving plate groups move away from each other, so that the rolling block can crush the leaf bud, and, under the action of the rolling block, the tea stalk can rotate, causing the tea leaf to turn over, so that the crushing is more complete and the effect is better. Then, the motor is reversed to drive the fourth moving plate, the first moving plate and the second moving plate to move upward. At the same time, the sliding pin slides upward along the inclined section, so that the first moving plate, the second moving plate and the third moving plate move back to their original positions, causing the rolling block to be separated from the tea leaf briefly. Repeating this process can make the first moving plate and the second moving plate move reciprocally. At the same time, the first moving plate and the second moving plate are arranged alternately and move in opposite directions. Under the conveying action of the conveyor belt, it can prevent the rolling block from deflecting the tea leaf to one side, enabling the rolling block to intermittently reciprocally rub and crush the leaf bud. At the same time, it can prevent the rolling block from continuously rubbing the tea stalk, avoiding the crushing of the tea stalk, and separating and collecting the leaf bud powder and the tea stalk through the collection mechanism, improving the efficiency of preparing natural tea essence, avoiding the waste of enzymes in the enzymatic hydrolysis process, and improving the purity and quality of natural tea essence.

[0024] (3) For a crusher and crushing method for preparing natural tea essence according to the present invention, by providing a pressure regulating mechanism, etc., when the first moving plate and the second moving plate drive the rolling block to move downward through the pressure regulating mechanism and abut against the tea leaves, the sliding disk is thus pushed to move upward along the inner wall of the air storage pipe, squeezing the air in the air storage pipe. When the pressure in the air storage pipe reaches the maximum value, the sealing ball is pushed to move. At the same time, the second spring is compressed, so that the sealing ball no longer abuts against the conical pipe, and thus the air in the sliding disk is discharged through the exhaust pipe, thereby controlling the maximum squeezing force of the connecting disk on the tea leaves, ensuring that it can crush the leaf buds without crushing the tea stalks, guaranteeing the crushing effect. Moreover, by rotating the rocker, the rotation of the rocker drives the rotation of the second threaded rod, and then drives the filter disk to move, that is, adjusting the compression amount of the second spring and the squeezing force between the sealing ball and the conical pipe, and further adjusting the maximum squeezing force of the rolling block on the tea leaves, with stronger applicability and better use effect.

[0025] (4) For a crusher and crushing method for preparing natural tea essence according to the present invention, by providing a collection mechanism, etc., during crushing, the exhaust fan is started, and air is exhausted through the connecting pipe, so that the leaf bud powder crushed by being intermittently rubbed back and forth by the rolling block enters the collection cover through the filter holes, and is sucked through the connecting pipe and then sent into the filter box for collection. Under the filtering action of the filter plate, the leaf bud powder falls into the collection box for collection, while the unbroken tea stalks continue to be conveyed along the conveyor belt and then fall into the collection box for collection, thus facilitating the classified collection of the leaf bud powder and the tea stalks.

[0043] As Figures 1 - 13 shown, a crusher for preparing natural tea essence according to the present invention includes a bottom plate 1 and a conveyor 11 provided on the upper side wall of the bottom plate 1. The conveyor 11 includes a conveyor belt 1101, and a plurality of filter holes 12 are arranged in an array on the surface of the conveyor belt 1101. The upper side wall of the bottom plate 1 is fixedly connected with an L-shaped support plate 13. A crushing mechanism for crushing tea buds is provided on the upper side wall of the support plate 13, and a collection mechanism for collecting tea powder is provided on the upper side wall of the support plate 13. It can crush the tea buds alone without crushing the tea stalks. Moreover, it is convenient to classify and collect the crushed tea powder and tea stalks, thereby increasing the effective content in the tea powder. This can not only improve the efficiency of preparing natural tea essence, but also avoid waste of enzymes in the enzymatic hydrolysis process, and improve its preparation purity and quality.

[0044] The crushing mechanism includes multiple groups of moving plate groups arranged in an array. Each group of moving plate groups includes a first moving plate 201 and a second moving plate 202. The moving plate groups are connected to the upper side wall of the support plate 13 through a lifting mechanism. A plurality of pushing components for pushing the moving plate groups to move are arranged on the upper side wall of the support plate 13, and the pushing components are located on both sides of the conveyor belt 1101. A plurality of reset components for resetting each group of moving plate groups are arranged on the upper side wall of the support plate 13, and the reset components are located on both sides of the conveyor belt 1101. The lower side wall of the moving plate group is connected with a plurality of third moving plates 203 arranged in an array through a pressure regulating mechanism. The lower side wall of the third moving plate 203 is fixedly connected with a plurality of crushing blocks 204 arranged in an array. The crushing blocks 204 include two symmetrically arranged rounded corners 205. Under the action of the pushing component, the first moving plate 201 and the second moving plate 202 reciprocate. At the same time, the first moving plate 201 and the second moving plate 202 are arranged alternately, and the moving directions are opposite. Under the conveying action of the conveyor belt 1101, it can be avoided that the crushing blocks 204 push the tea leaves to one side, so that the crushing blocks 204 can intermittently reciprocate and rub and crush the leaf buds. At the same time, it can be avoided that the crushing blocks 204 keep rubbing the tea stalks, which can avoid the breakage of the tea stalks. The leaf bud powder and the tea stalks are separately collected through the collecting mechanism, which improves the efficiency of preparing natural tea essence, avoids the waste of enzymes in the enzymolysis process, and improves the purity and quality of natural tea essence. At the same time, under the action of the reset component, the crushing blocks 204 can be briefly separated from the tea leaves, avoiding the crushing blocks 204 from continuously rubbing the tea stalks, which can avoid the breakage of the tea stalks. Moreover, under the action of the pressure regulating mechanism, it is ensured that the crushing blocks 204 can only crush the leaf buds, and the tea stalks will not be crushed.

[0045] The collection mechanism includes a collection groove 302 opened on the upper side wall of the support plate 13, and a collection cover 303 is fixedly connected to the bottom of the collection groove 302. A fixed plate 304 is fixedly connected to the side wall of the support plate 13, and an exhaust fan 305 is fixedly connected to the side wall of the fixed plate 304.

An air outlet pipe 308 is fixedly connected to the side wall of the filter box 307, and a filter plate 309 is fixedly connected to one end of the air outlet pipe 308 close to the filter box 307. A collection box 301 for collecting tea stalks is arranged on the upper side wall of the bottom plate 1. During crushing, the exhaust fan 305 is started, and air is drawn through the connecting pipe 306, so that the leaf bud powder crushed by the intermittent reciprocating rubbing of the rolling block 204 enters the collection cover 303 through the filter holes 12, and is sucked through the connecting pipe 306 and then sent into the filter box 307 for collection. Under the filtering action of the filter plate 309, the leaf bud powder falls into the collection box 310 for collection, while the uncrushed tea stalks continue to be conveyed by the conveyor belt 1101 and then fall into the collection box 301 for collection, thus facilitating the classified collection of leaf bud powder and tea stalks.

The motor 608 is started, and the rotation of the motor 608 drives the rotation of the first threaded rod 607, thereby driving the fourth moving plate 605 to move up and down. Moreover, when the fourth moving plate 605 moves, it can form a vibration effect on the conveyor belt 1101, which not only facilitates the flattening of the tea leaves on the conveyor belt 1101 to avoid stacking, so that the subsequent crushing effect is better, but also facilitates the collection of the tea leaf powder on the conveyor belt 1101 after the crushing is completed.

When the fourth moving plate 605 moves, it drives the third connecting plate 1401 to move downward synchronously, so that the convex strips 1402 are successively abutted against and slide on the sidewall of the conveyor belt 1101, thereby forming a vibration effect on the conveyor belt 1101.

[0049] The reset assembly is fixedly connected to the first connection block 901 on the sidewall of each moving plate group. Two symmetrically arranged first fixing blocks 902 are fixedly connected to the lower sidewall of the first connection block 901.

An air inlet pipe 405 is fixedly connected to the side wall of the air storage pipe 401. A one-way valve is fixedly connected in the air inlet pipe 405. The conducting direction of the one-way valve is from the outside to the inside of the air storage pipe 401. An exhaust pipe 406 is fixedly connected to the side wall of the air storage pipe 401. A tapered pipe 407 is fixedly connected in the exhaust pipe 406. A filter disk 408 is connected in the exhaust pipe 406 through a moving mechanism. A sealing ball 410 is connected to the side wall of the filter disk 408 through a second spring 409. The sealing ball 410 abuts against the inner side wall of the tapered pipe 407. When the first moving plate 201 and the second moving plate 202 drive the rolling block 204 to move downward through the pressure regulating mechanism and abut against the tea leaves, the sliding disk 402 is pushed to move upward along the inner side wall of the air storage pipe 401, squeezing the air in the air storage pipe 401. When the pressure in the air storage pipe 401 reaches the maximum value, the sealing ball 410 is pushed to move. At the same time, the second spring 409 is compressed, so that the sealing ball 410 no longer abuts against the tapered pipe 407, and the air in the sliding disk 402 is discharged through the exhaust pipe 406, thereby controlling the maximum squeezing force of the connecting disk 404 on the tea leaves, ensuring that it can crush the tea buds but not the tea stalks, ensuring the crushing effect. And when the moving plate group moves upward to reset, under the gravity of the third moving plate 203, the rolling block 204, etc., the sliding disk 402 slides downward to reset. At the same time, external air enters the air storage pipe 401 through the air inlet pipe 405.

[0051] The moving mechanism includes a second fixed block 501 and a third fixed block 502 fixedly connected to the side wall of the exhaust pipe 406. A third sleeve rod 503 is fixedly connected to the side wall of the second fixed block 501. A third sleeve 504 is sleeved on the side wall of the third sleeve rod 503. The other end of the third sleeve 504 is fixedly connected to the side wall of the filter disc 408. A second threaded pipe 505 is fixedly connected to the side wall of the filter disc 408. A second threaded rod 506 is threadedly connected inside the second threaded pipe 505. The other end of the second threaded rod 506 is rotatably connected to the side wall of the third fixed block 502. A handwheel 507 is fixedly connected to the other end of the second threaded rod 506. A scale mark 508 is provided on the side wall of the exhaust pipe 406. By rotating the handwheel 507, the rotation of the handwheel 507 drives the rotation of the second threaded rod 506, thereby driving the filter disc 408 to move. By observing the scale mark 508, the compression amount of the second spring 409 and the extrusion force between the sealing ball 410 and the conical pipe 407 can be adjusted, and further the maximum extrusion force of the rolling block 204 on the tea leaves can be adjusted, with stronger applicability and better use effect.

[0052] Each driving mechanism includes a U-shaped plate 701 fixedly connected to the upper side wall of the support plate 13. A strip-shaped opening 702 is formed in the side wall of the U-shaped plate 701. The first connecting block 901 slides in the strip-shaped opening 702. Two symmetrically arranged sliding grooves in a triangular shape are formed in two opposite side walls of the U-shaped plate 701. The sliding groove includes a vertical section 703, a horizontal section 704, and an inclined section 705. Two symmetrically arranged sliding pins 706 are fixedly connected to the side wall of the first connecting block 901, and the sliding pins 706 slide in the sliding groove. The side wall of the U-shaped plate 701 is rotatably connected to a rotating block 1002 through a rotating pin 1001, and a stop block 1003 is fixedly connected to the side wall of the rotating block 1002. A stop rod 1004 is fixedly connected to the side wall of the U-shaped plate 701. When the fourth moving plate 605 moves downward, it drives the first moving plate 201, the second moving plate 202, and the third moving plate 203 to move downward synchronously. At the same time, the sliding pin 706 slides downward along the vertical section 703. When the rolling block 204 abuts against the leaf buds or tea stalks of the tea leaves, and under the action of the pressure regulating mechanism, the leaf buds are crushed, while the tea stalks are not crushed. When the sliding pin 706 slides to the bottom of the vertical section 703, under the action of the first spring 904, the sliding pin 706 slides along the horizontal section 704. At this time, the first moving plate 201 and the second moving plate 202 on each group of moving plate groups move away from each other, so that the rolling block 204 can crush the leaf buds, and, under the action of the rolling block 204, the tea stalks can be rotated to turn the tea leaves over. If the rolling block 204 presses on the tea stalks, when the sliding plate moves, the tea stalks can be rotated to turn the tea leaves over. If the rolling block 204 presses on the leaf buds, after the leaf buds are crushed, under the action of the rounded corner 205, the tea stalks can also be pushed to rotate to turn the tea leaves over, so that the crushing is more complete and the effect is better. Then, the motor 608 is reversed to drive the fourth moving plate 605, the first moving plate 201, and the second moving plate 202 to move upward. At the same time, the sliding pin 706 slides upward along the inclined section 705, so that the first moving plate 201, the second moving plate 202, and the third moving plate 203 move back to their original positions, and the rolling block 204 is briefly separated from the tea leaves. Repeating this way, the first moving plate 201 and the second moving plate 202 can move back and forth. At the same time, the first moving plate 201 and the second moving plate 202 are arranged alternately, and the moving directions are opposite. Under the conveying action of the conveyor belt 1101, it can prevent the rolling block 204 from pushing the tea leaves to one side, so that the rolling block 204 can intermittently reciprocate and rub and crush the leaf buds, and at the same time, it can prevent the rolling block 204 from continuously rubbing the tea stalks, avoid the tea stalks from being broken, and separate and collect the leaf bud powder and the tea stalks through the collecting mechanism, improve the efficiency of preparing natural tea essence, avoid the waste of enzymes in the enzymolysis process, and improve the purity and quality of natural tea essence.

[0053] A crushing method for preparing natural tea essence, comprising the following steps:

[0054] S1: Place the tea leaves on the conveyor belt 1101 for transportation. At the same time, start the motor 608. The rotation of the motor 608 drives the rotation of the first threaded rod 607, which in turn drives the fourth moving plate 605 to move downward. When the fourth moving plate 605 moves downward, it drives the third connecting plate 1401 to move downward synchronously, so that the convex strip 1402 abuts against and slides along the side wall of the conveyor belt 1101 in turn, thereby forming a vibration effect on the conveyor belt 1101, so as to spread the tea leaves on the conveyor belt 1101 flat and avoid stacking, so that the subsequent crushing effect is better. Moreover, after the crushing is completed, when the fourth moving plate 605 moves upward, the convex strip 1402 will also form a vibration effect on the conveyor belt 1101, so as to facilitate the collection of the tea powder on the conveyor belt 1101;

[0055] S2: When the fourth moving plate 605 moves downward, it drives the first moving plate 201, the second moving plate 202 and the third moving plate 203 to move downward synchronously. At the same time, the sliding pin 706 slides downward along the vertical section 703. When the rolling block 204 abuts against the leaf bud or tea stalk of the tea leaves and under the action of the pressure regulating mechanism, the leaf bud is crushed, while the tea stalk is not crushed. When the first moving plate 201 and the second moving plate 202 drive the rolling block 204 to move downward through the pressure regulating mechanism and abut against the tea leaves, it pushes the sliding disk 402 to move upward along the inner wall of the air storage pipe 401, squeezing the air in the air storage pipe 401. When the pressure in the air storage pipe 401 reaches the maximum value, it pushes the sealing ball 410 to move. At the same time, the second spring 409 is compressed, so that the sealing ball 410 no longer abuts against the conical pipe 407, so that the air in the sliding disk 402 is discharged through the exhaust pipe 406, so as to control the maximum squeezing force of the connecting disk 404 on the tea leaves, ensure that it can crush the leaf buds and not crush the tea stalks, ensure the crushing effect, and by rotating the rocker 507, the rotation of the rocker 507 drives the rotation of the second threaded rod 506, which in turn drives the filter disk 408 to move, that is, adjust the compression amount of the second spring 409 and the squeezing force between the sealing ball 410 and the conical pipe 407, and then adjust the maximum squeezing force of the rolling block 204 on the tea leaves, with stronger applicability and better use effect;

[0056] S3: When the sliding pin 706 slides to the bottom of the vertical section 703, under the action of the first spring 904, the sliding pin 706 slides along the horizontal section 704. At this time, the first moving plate 201 and the second moving plate 202 on each group of moving plate groups move away from each other, so that the rolling block 204 can crush the leaf buds, and under the action of the rolling block 204, the tea stalk can be rotated to turn the tea leaves over, so that the crushing is more complete and the effect is better;

[0057] S4: Reverse the motor 608 to drive the fourth moving plate 605, the first moving plate 201 and the second moving plate 202 to move upward. At the same time, the sliding pin 706 slides upward along the inclined section 705, so that the first moving plate 201, the second moving plate 202 and the third moving plate 203 move back to their original positions, causing the rolling block 204 to be briefly separated from the tea leaves. Repeating this process can make the first moving plate 201 and the second moving plate 202 move back and forth. At the same time, the first moving plate 201 and the second moving plate 202 are arranged alternately and move in opposite directions. Under the conveying action of the conveyor belt 1101, it can prevent the rolling block 204 from pushing the tea leaves to one side, enabling the rolling block 204 to intermittently and reciprocally rub and crush the leaf buds. At the same time, it can prevent the rolling block 204 from continuously rubbing the tea stalks and avoid breaking the tea stalks;

[0058] S5: During crushing, start the exhaust fan 305 to draw air through the connecting pipe 306. At the same time, when the fourth moving plate 605 moves upward, the convex strip 1402 will also vibrate the conveyor belt 1101, causing the leaf bud powder intermittently and reciprocally rubbed and crushed by the rolling block 204 to enter the collection cover 303 through the filter holes 12, and be sucked through the connecting pipe 306 and then sent into the filter box 307 for collection. Under the filtering action of the filter plate 309, the leaf bud powder falls into the collection box 310 for collection, while the unbroken tea stalks continue to be conveyed by the conveyor belt 1101 and then fall into the collection box 301 for collection, thus facilitating the classified collection of the leaf bud powder and the tea stalks.

A method of crushing using the crusher for preparing natural tea essence according to any one of claims 1 to 6, characterized in that, The method includes the following steps: S1: Place the tea leaves on the conveyor belt (1101) for conveyance. Meanwhile, start the motor (608). The rotation of the motor (608) drives the rotation of the first threaded rod (607), which in turn drives the fourth moving plate (605) to move downward. When the fourth moving plate (605) moves downward, it drives the third connecting plate (1401) to move downward synchronously, causing the convex strips (1402) to successively abut against and slide along the side wall of the conveyor belt (1101), thereby forming a vibration effect on the conveyor belt (1101), flattening the tea leaves on the conveyor belt (1101) to avoid stacking. S2: When the fourth moving plate (605) moves downward, it drives the first moving plate (201), the second moving plate (202), and the third moving plate (203) to move downward synchronously. Meanwhile, the sliding pin (706) slides downward along the vertical section (703). When the rolling block (204) abuts against the leaf buds or tea stalks of the tea leaves and under the action of the pressure regulating mechanism, the leaf buds are crushed, while the tea stalks are not crushed. S3: When the sliding pin (706) slides to the bottom of the vertical section (703), under the action of the first spring (904), the sliding pin (706) slides along the horizontal section (704). At this time, the first moving plate (201) and the second moving plate (202) on each group of moving plate groups move away from each other, so that the rolling block (204) can crush the leaf buds, and under the action of the rolling block (204), the tea stalks can rotate, turning the tea leaves over, making the crushing more complete and with a better effect. S4: Reverse the motor (608) to drive the fourth moving plate (605), the first moving plate (201), and the second moving plate (202) to move upward. At the same time, the sliding pin (706) slides upward along the inclined section (705), so that the first moving plate (201), the second moving plate (202), and the third moving plate (203) move back to their original positions, causing the rolling block (204) to be briefly separated from the tea leaves. Repeating this process, the first moving plate (201) and the second moving plate (202) can move back and forth. At the same time, the first moving plate (201) and the second moving plate (202) are arranged alternately and move in opposite directions. Under the conveying action of the conveyor belt (1101), it can prevent the rolling block (204) from pushing the tea leaves to one side, enabling the rolling block (204) to intermittently reciprocally rub and crush the leaf buds, and at the same time, it can prevent the rolling block (204) from continuously rubbing the tea stalks, avoiding the breakage of the tea stalks. S5: When crushing, start the exhaust fan (305), and conduct air extraction through the connecting pipe (306). At the same time, when the fourth moving plate (605) moves upward, the convex strip (1402) will also form a vibration effect on the conveyor belt (1101), causing the intermittently reciprocating rubbing and crushing of the crushed leaf bud powder by the rolled blocks (204) to enter the collection hood (303) through the filter holes (12), and being sucked in through the connecting pipe (306) and then sent into the filter box (307) for collection. Under the filtering action of the filter plate (309), the leaf bud powder falls into the collection box (310) for collection, while the unbroken tea stalks continue to be conveyed by the conveyor belt (1101) and then fall into the collection box (301) for collection, thus facilitating the classified collection of the leaf bud powder and the tea stalks.
