[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1

[0029] A tea grinding device, such as Figures 1 to 6As shown, the device includes a base 1, a bracket 9 is fixed to the top outer wall of the base 1 by bolts, a storage component is installed on one side inner wall of the bracket 9, a storage cylinder 5 is fixed to the top of the bracket 9 by bolts, a limit ring 7 is fixed to the bottom of the storage cylinder 5, and the bottom of the limit ring 7 and the storage component are connected by a feeding pipe 13. A drive motor 6 is fixed to one side outer wall of the bracket 9 by bolts, and a rotating column 15 is connected to the output end of the drive motor 6 by a coupling. A through hole 14 is opened inside the rotating column 15, and a grinding roller is installed on one side outer wall of the rotating column 15.

[0030] The storage cylinder 5 can be used to store tea leaves that need to be ground. In the initial state, the through hole 14 and the bottom of the storage cylinder 5 are misaligned to ensure that the bottom of the storage cylinder 5 is blocked by the rotating column 15, preventing the tea leaves from overflowing. When the tea leaves need to be ground, the drive motor 6 drives the rotating column 15 to rotate. When the through hole 14 on the rotating column 15 rotates to a relative opening with the bottom of the storage cylinder 5, the tea leaves in the storage cylinder 5 enter the through hole 14 through the bottom of the storage cylinder 5, and finally enter the storage component through the through hole 14 and the feed pipe 13. Then, the limiting ring 7 indirectly drives the grinding roller to reciprocate at a certain angle. During the reciprocating swing, the grinding component reciprocates to grind the tea leaves in the storage component. At the same time, during this process, the through hole 14 and the bottom of the storage cylinder 5 intermittently open, so that the tea leaves are intermittently fed during the grinding process, so as to avoid the tea leaves in the storage component not being replenished in time after grinding.

[0031] The storage assembly includes an arc-shaped box 3 and a connecting plate 8. The connecting plate 8 is fixed to the inner wall of one side of the bracket 9 by bolts, and the arc-shaped box 3 is fixed to one end of the connecting plate 8 by bolts. A screen 12 is fixed to the bottom of the arc-shaped box 3.

[0032] The tea leaves to be ground are stored in the arc-shaped box 3. After the tea leaves are ground by the grinding rollers, the ground tea leaves are sieved by the screen 12. Tea leaves that meet the grinding particle size fall through the screen 12, while tea leaves that do not meet the grinding particle size are retained by the screen 12 and continue to be ground by the grinding components, thereby ensuring the grinding effect and avoiding the problem of incomplete grinding of tea leaves.

[0033] The grinding roller assembly includes an intermediate rod 16 and a connecting frame 17. The intermediate rod 16 is welded to the outer wall of one side of the rotating column 15, and the connecting frame 17 is welded to one end of the intermediate rod 16. An electric telescopic rod 4 is fixed to the top outer wall of the connecting frame 17 by bolts, and a fixed seat 20 is fixed to the output end of the electric telescopic rod 4 by pins. A U-shaped frame 18 is welded to the bottom of the fixed seat 20, and a grinding roller 19 is rotatably connected between the inner walls on both sides of the U-shaped frame 18.

[0034] The gap between the grinding roller 19 and the inner wall of the arc-shaped box 3 can be adjusted by using the electric telescopic rod 4. When the grinding roller 19 reciprocates under the indirect drive of the drive motor 6, the grinding roller 19 grinds the tea surface by rolling.

[0035] A collection box 2 is installed on the top outer wall of the base 1 via a positioning component;

[0036] The ground tea leaves can be collected using collection box 2.

[0037] The positioning component includes a positioning block 10 and a positioning groove 23. The positioning block 10 is fixed to the top outer wall of the base 1 by screws, and the positioning groove 23 is opened at the bottom of the collection box 2. The positioning groove 23 and the positioning block 10 are positioned by insertion.

[0038] The positioning groove 23 at the bottom of the collection box 2 is connected to the positioning block 10 to prevent personnel from accidentally touching the collection box 2 with their feet or hands during the collection process, which could cause the collection box 2 to move or open, thus ensuring the safety of the collection.

[0039] Working principle: The storage cylinder 5 stores the tea leaves to be ground. Initially, the through hole 14 in the rotating column 15 and the bottom of the storage cylinder 5 are misaligned, preventing the tea leaves from overflowing. When grinding is required, the drive motor 6 is started. The output of the drive motor 6 drives the rotating column 15 to rotate via a coupling. When the through hole 14 on the rotating column 15 rotates to a relative opening with the bottom of the storage cylinder 5, the tea leaves in the storage cylinder 5 enter the through hole 14 through the bottom of the storage cylinder 5, and finally enter the arc-shaped box 3 in the storage assembly through the through hole 14 and the feed pipe 13. During the rotation of the rotating column 15 driven by the drive motor 6, the grinding rollers are indirectly driven to reciprocate at a certain angle. When the grinding rollers are working, the electric telescopic rod 4 can... The gap between the grinding roller 19 and the inner wall of the arc-shaped box 3 is adjusted. The grinding roller 19 reciprocates under the indirect drive of the drive motor 6. During the reciprocating motion, the grinding roller 19 grinds the tea leaves in the arc-shaped box 3 by rolling. The tea leaves after being ground by the grinding roller 19 remain in the arc-shaped box 3. The ground tea leaves are sieved by the screen 12 at the bottom of the arc-shaped box 3. Tea leaves that meet the grinding particle size fall through the screen 12, while tea leaves that do not meet the grinding particle size are intercepted by the screen 12 and continue to be ground by the grinding components. This ensures the grinding effect and avoids the problem of incomplete grinding of the tea leaves. A collection box 2 is installed on the top outer wall of the base 1 through a positioning component. The ground tea leaves that fall through the screen 12 fall into the collection box 2 to collect the ground tea leaves.

[0040] Example 2

[0041] A tea grinding device, in order to improve grinding efficiency, such as Figures 1 to 6 As shown, this embodiment makes the following additions based on embodiment 1: a cleaning assembly is installed on one side of the outer wall of the fixed base 20. The cleaning assembly includes a nozzle 21 and a pad 22. The pad 22 is fixed to the side wall of the fixed base 20 by bolts, and the nozzle 21 is fixed to the surface of the pad 22.

[0042] After grinding, some tea leaves will adhere to the inner wall of the arc-shaped box 3 and the surface of the screen 12. If they are not cleaned, they are prone to mold growth and affect subsequent use. By setting up a spray nozzle 21, when its top is connected to a water pipe (not shown) via a connector, the inner wall of the arc-shaped box 3 and the surface of the screen 12 can be cleaned by rinsing. Since the spray nozzle 21 can reciprocate with the grinding rollers, it can clean different parts of the inner wall of the arc-shaped box 3, thereby avoiding cleaning dead corners.

[0043] A lever frame 11 is installed on both sides of the connecting frame 17;

[0044] The agitator 11 is U-shaped, which agitates the tea leaves in the arc-shaped box 3 when the agitator 11 reciprocates according to the grinding roller, thereby making the contact between the tea leaves and the grinding roller 19 more uniform and preventing some tea leaves from adhering to the inner wall of the arc-shaped box 3 so that the grinding roller 19 cannot contact them for grinding.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
