Description
Technical Field
[0001] The utility model belongs to the technical field of tea processing, and particularly relates to a tea leaf uniformly crushing device. Background Art
[0002] Currently, tea processing typically requires crushing the leaves to separate the green tea leaves for use in tea bags, animal feed, or other applications. Therefore, the quality of the crushed leaves is crucial for subsequent tea processing. However, most existing tea crushers can only crush the leaves once, resulting in uneven crushing. If the crushed leaves do not meet the requirements, they must be manually transferred and crushed again, which is cumbersome and inconvenient, hindering subsequent tea processing and requiring improvement. Utility Model Content
[0003] In view of this, the purpose of the present invention is to provide a tea leaf uniform crushing device, which can achieve multiple uniform and effective crushing of tea leaves by automatically turning the crushing drum at a certain time, so as to solve the above problems.

The conical guide groove has two small-diameter ends arranged opposite to each other and connected through a square crushing groove opened at the center of the dividing column. Turntables are rotatably provided on the left and right groove walls of the crushing groove. One turntable is coaxially fixedly connected to the output shaft of the second motor built into the dividing column on the side away from the other turntable. The opposite sides of the two turntables are detachably connected with support plates. Crushing shafts are fixedly connected between the centers of the two support plates and between the edges of the two support plates, and the crushing shafts located at the edges are circumferentially spaced and evenly distributed on the circumferential side of the crushing shaft located in the center. Each crushing shaft is fixed with crushing blades, and the crushing blades on the crushing shafts located at the edges are staggered with the crushing blades on the crushing shaft located in the center. The bottom of the crushing barrel is in an inverted cone and is connected to a discharge pipe with a discharge valve.
[0005] Preferably, electric push rods are fixedly provided on the upper parts of the left and right outer sides of the crushing cylinder, and the telescopic ends of the electric push rods face upward and are fixedly connected to the cover plate.
[0006] Preferably, magnets are embedded in the centers of opposite sides of the two turntables, and a number of internally threaded blind holes are opened on the edges at uniform circumferential intervals. The support plate is magnetic and a number of internally threaded through holes are opened on the edges at uniform circumferential intervals. The support plate abuts against the corresponding turntable and is magnetically connected to the corresponding magnet. The internally threaded through holes correspond one-to-one to the internally threaded blind holes on the same side, and the same butterfly bolt is screwed between the corresponding internally threaded through holes and the internally threaded blind holes.
[0007] Preferably, the support plate is adapted to the corresponding turntable.
[0008] Preferably, the internally threaded through hole is matched with the corresponding internally threaded blind hole and both are matched with the corresponding butterfly bolt.
[0009] The present invention has the following beneficial effects: when crushing tea leaves, the feed valve is first opened, and the tea leaves are fed into the crushing drum through the feed pipe. The tea leaves are then guided by the guide grooves on the upper side of the dividing column and flow into the crushing trough. Simultaneously, the second motor is operated to drive the two rotating discs, the support disc between the two rotating discs, and the multiple crushing shafts to rotate, so that the crushing blades on the crushing shafts can crush the passing tea leaves once. The coordination between the central crushing shaft and the multiple side crushing shafts, as well as the staggered distribution of the crushing blades on both, effectively enhances the crushing effect and ensures overall crushing quality. The tea leaves after the primary crushing fall into the crushing drum below the dividing column. After the entire batch of tea leaves has been crushed, the feed valve is closed, and the first motor is operated again, driving the entire crushing drum to rotate 180 degrees, thereby inverting the entire crushing drum and automatically bringing the primary crushed tea leaves to the upper side. Guided by the corresponding guide grooves, the primary crushed tea leaves can then re-enter and flow through the crushing trough, achieving a second crushing of the tea leaves. At the same time, a timer starts running. After reaching the set time, an electrical signal is sent to the controller, causing it to automatically control the first motor to operate again, causing the crushing drum to rotate 180 degrees again, completing the third crushing process of the tea leaves as described above. This cycle, coordinated with each other, allows the crushing drum to automatically rotate at regular intervals to achieve multiple, uniform and effective crushing of the tea leaves. The final crushed tea leaves are more uniform, meeting actual needs, and without the need for manual transfer and crushing, making operation simpler and more convenient, and facilitating subsequent processing of the tea leaves. After crushing, the angle of the crushing drum is adjusted so that the discharge pipe faces downward, and the discharge valve is opened to discharge the tea leaves through the discharge pipe. Furthermore, the adjustable cover plate, the fixed connection between the divider column and the cover plate, and the removable connection between the support disk and the turntable allow the entire divider column to be easily removed from the crushing drum and the support disk to be flexibly disassembled and assembled, allowing for convenient replacement of the crushing blades when needed, making the device more convenient and practical.

DETAILED DESCRIPTION
[0019] The present invention is described in further detail below with reference to the accompanying drawings and specific embodiments:
[0020] like Figures 1 to 8As shown, a tea leaf uniformly crushing device comprises a base 1, with support plates 2 fixed vertically on either side of the base 1. A horizontal, rotatable shaft 3 is mounted on the upper portion of each support plate 2. A first motor 4 is connected to one end of the shaft 3, remote from the other. A controller 5 and a timer 6 are fixed to the side of the support plate 2 on the same side as the first motor 4. Both the first motor 4 and the timer 6 are electrically connected to the controller 5. A crushing drum 7 is fixedly connected between the two shafts 3. The top of the crushing drum 7 is open and abutted against a liftable cover plate 8. A feed pipe 10 with a feed valve 9 is connected to the center of the cover plate 8. A separator column 11 is abutted and sleeved within the center of the crushing drum 7. The separator column 11 is fixedly connected to the cover plate 8 via a plurality of connecting rods 12. Conical guide grooves 13 are defined at both the top and bottom of the separator column 7. The smaller diameter ends of the two guide grooves 13 are positioned opposite each other and connected by a square crushing groove 14 defined at the center of the separator column 11. Rotating discs 15 are mounted on the left and right walls of the crushing trough 14. The side of one disc 15 facing away from the other is coaxially fixedly connected to the output shaft of a second motor 16 built into the partition column 11. Support discs 17 are detachably connected to the opposing sides of the two discs 15. Crushing shafts 18 are fixedly connected between the centers of the two support discs 17 and between the edges of the two support discs 17. The edge crushing shafts 18 are circumferentially spaced and uniformly distributed around the center crushing shaft 18. Crushing blades 19 are fixedly mounted on each crushing shaft 18. The crushing blades 19 on the edge crushing shafts 18 are staggered with those on the center crushing shaft 18. The bottom of the crushing barrel 7 is inverted conical and connected to a discharge pipe 21 with a discharge valve 20.
[0021] To crush tea leaves, first open the feed valve 9 and feed the tea leaves into the crushing drum 7 through the feed pipe 10. The tea leaves flow into the crushing trough 14, guided by the guide groove 13 on the upper side of the partition column 11. Simultaneously, the second motor 16 is operated, driving the two rotating discs 15, the support disc 17 between them, and the multiple crushing shafts 18 to rotate. The crushing blades 19 on the crushing shafts 18 then crush the passing tea leaves. The coordination between the central crushing shaft 18 and the multiple side crushing shafts 18, as well as the staggered arrangement of the crushing blades 19 on each, effectively enhances the crushing effect and ensures overall crushing quality. The crushed tea leaves fall into the crushing drum 7 below the partition 11. After the entire batch of tea leaves has been crushed, the feed valve 10 is closed and the first motor 4 is operated, driving the entire crushing drum 7 to rotate 180 degrees, causing the entire crushing drum 7 to invert, automatically bringing the crushed tea leaves to the upper side. Guided by the corresponding guide grooves 13, the crushed tea leaves can then re-enter and flow through the crushing trough 14, completing the second crushing process. Simultaneously, the timer 6 starts operating and, after reaching a set time, sends an electrical signal to the controller 5, causing it to automatically control the first motor 4 to operate again, driving the crushing drum 7 to rotate 180 degrees again, completing the third crushing process as described above. This cycle, in conjunction with each other, allows the tea leaves to be crushed uniformly and effectively multiple times through the timed automatic rotation of the crushing drum 7. The resulting crushed tea leaves are more uniform, meeting actual requirements, and without the need for manual transfer and crushing, making the operation simpler and more convenient, and more conducive to the subsequent processing of the tea leaves. After crushing, adjust the angle of the crushing barrel 7 so that the discharge pipe 21 faces downward, then open the discharge valve 20 and discharge the material through the discharge pipe 21. In addition, through the liftable setting of the cover plate 8, the fixed connection between the partition column 11 and the cover plate 8, and the detachable connection between the support plate 17 and the turntable 15, in actual use, the entire partition column 11 can be easily removed from the crushing barrel 7 and the support plate 17 can be flexibly disassembled and assembled, so that the entire crushing blade 19 can be easily replaced when needed, making the device as a whole more convenient and practical. The first motor 4 can use an existing conventional stepping motor with a brake function to cooperate with the rotation of the corresponding angle and the position locking after rotation into place. The controller 5 and the timer 6 can both use existing technologies, and their specific models can be selected according to actual conditions. No specific restrictions are made here. Their specific structure and working principle are all existing technologies and will not be described in detail here.
[0022] In this embodiment, electric push rods 22 are fixedly provided on the upper parts of the left and right outer sides of the crushing barrel 7. The telescopic ends of the electric push rods 22 face upward and are fixedly connected to the cover plate 8. Therefore, during use, the telescopic ends of the electric push rods 22 can be extended and retracted to drive the cover plate 8 and the partition column 11 to be raised and lowered as a whole, thereby cooperating to realize the opening and closing of the crushing barrel 7 and the movement of the partition column 11, so as to facilitate the overall disassembly, assembly and replacement of the support plate 17 and the crushing shaft 18 between the support plates 17.
[0023] In this embodiment, magnets 23 are embedded in the centers of opposing sides of the two turntables 15, and a plurality of internally threaded blind holes 24 are formed on the edges of the two turntables 15 at evenly spaced intervals. The support discs 17 are magnetic and have a plurality of internally threaded through holes 25 formed on the edges at evenly spaced intervals. The support discs 17 abut the corresponding turntables 15 and are magnetically connected to the corresponding magnets 23. The internally threaded through holes 25 correspond one-to-one with the internally threaded blind holes 24 on the same side, and a common butterfly bolt 26 is screwed between the corresponding internally threaded through holes 25 and internally threaded blind holes 24. In actual use, when the crushing blades become damaged and need to be replaced, the machine can be stopped and the electric push rod 22 can be operated to extend its telescopic end, thereby driving the cover plate 8 and the separator 11 upward until the separator 11 is removed from the crushing barrel 7. The butterfly bolts 26 can then be removed and the support discs 17 can be pulled upward or downward from between the two turntables 15 to completely remove the original support discs 17 and the crushing shaft 18 between the support discs 17. Next, after obtaining the support disc 17 with intact crushing blades 19, it is inserted between the two turntables 15. The support disc 17 is initially positioned and installed through the magnetic connection between the corresponding magnets 23, aligning the internally threaded through-holes 25 with the internally threaded blind holes 24. Afterwards, the butterfly bolts 26 are screwed back into place, completing the secure installation of the new support disc 17. The installation is secure and does not affect subsequent crushing operations. This allows for convenient assembly and disassembly of the entire support disc 17. The butterfly bolts 26 are easily hand-tightened, making operation simpler and more convenient, facilitating the flexible replacement of the crushing blades 19 as a whole, and making the entire device more convenient and practical.
[0024] In this embodiment, the support plate 17 is adapted to the corresponding rotating plate 15 to ensure smooth connection and fixation between the two.
[0025] In this embodiment, the internal threaded through hole 25 is matched with the corresponding internal threaded blind hole 24 and both are matched with the corresponding butterfly bolt 26 to ensure smooth installation and fixation of the support plate 17 .
[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
