[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] One embodiment provided by this utility model: Reference Figures 1-3 A tea crushing and drying box includes a cylindrical body 1. A roller 2 is rotatably connected to the inner periphery of the cylindrical body 1. The outer wall of the roller 2 has filter holes. The roller 2 is conical in shape and has a gap between it and the inner wall of the cylindrical body 1 to allow airflow. A rotating shaft 3 is rotatably connected to the middle of the inner side of the cylindrical body 1. The rotating shaft 3 is driven to rotate by a motor. A crushing belt 4 for crushing tea leaves is fixedly connected to the outer wall of the rotating shaft 3. The crushing belt 4 is spirally wound around the outer wall of the rotating shaft 3, and convex teeth for assisting in crushing tea leaves are fixedly connected to its inner periphery. The spiral wound posture is adapted to the roller 2. The inner wall shape of the cylinder 2 is such that when the tea leaves are tumbled in the cylinder 2, the tea leaves are impacted by the rotating shaft 3 and the crushing belt 4 in the opposite direction, causing them to break. Both the cylinder 2 and the rotating shaft 3 are driven by meshing wheel sets. The right side of the cylinder 1 is fixedly connected to the air outlet 9 for discharging hot air. The inside of the air outlet 9 is equipped with a cleaning component to block and clean tea leaf debris. The cleaned tea leaf debris is collected by the collection component installed on the bottom side of the cylinder 1. The left side of the cylinder 1 is fixedly connected to the air inlet 16 for receiving hot air. The front side of the cylinder 1 is equipped with a cylinder cover 17 with a locking structure. Specifically, during the tea crushing process, the rotating shaft 3 and the drum 2 rotate in opposite directions, creating a speed difference. The drum 2 rotates at a slower speed to prevent the tea from being over-crushed. The rotating shaft 3 drives the connected crushing belt 4 to crush the tea inside the drum 2. At the same time, hot air enters the inside of the cylinder 1 through the air inlet 16 and comes into contact with the tea in the drum 2. As the drum 2 tumbles the tea, it allows the tea to fully interact with the hot air, causing the moisture to evaporate and be discharged from the air outlet 9 along with the hot air.

[0019] Reference Figures 2-4 The meshing gear set includes a planet carrier 8 fixedly connected to the rear side of the cylinder 1. Multiple planet gears 7 are rotatably connected to the middle end of the planet carrier 8. A sun gear 6 is meshed with the inner circumference of the multiple planet gears 7. The sun gear 6 is fixedly connected to the rear end of the rotating shaft 3. A toothed ring 5 is meshed with the outer circumference of the multiple planet gears 7. The toothed ring 5 is fixedly connected to the rear side of the roller 2. Specifically, the motor drives the rotating shaft 3 to rotate. The rotating shaft 3 rotates by meshing multiple planetary gears 7 with the sun gear 6 on its outer wall. The planetary gears 7 then mesh synchronously with the gear ring 5 connected to the outer ring of the roller 2 to rotate, so that the rotating shaft 3 and the roller 2 rotate in opposite directions.

[0020] Reference Figure 2 and Figure 5 The cleaning assembly includes a brush 11 that slides horizontally in the middle of the inner wall of the air outlet 9. A filter screen 10 for intercepting debris is provided on the top side of the brush 11, and the filter screen 10 is fixedly connected to the inner wall of the air outlet 9. A reciprocating screw 12 is rotatably connected to the rear side of the upper air outlet 9. The rear end of the brush 11 is sleeved on the outer wall of the reciprocating screw 12. The rear end of the reciprocating screw 12 is connected to the outer wall of the rear end of the rotating shaft 3 through two synchronous pulleys driven by a synchronous belt. Specifically, as the hot air is discharged from the air outlet 9, the tea leaves will pass through the roller 2 and arrive at the air outlet 9 along with the hot air. The filter screen 10 on the inner wall of the air outlet 9 will intercept them, causing the tea leaves to accumulate on the filter screen 10. The rotating shaft 3 drives the reciprocating screw 12 to rotate through the synchronous belt and synchronous pulley. This causes the reciprocating screw 12 to drive the brush 11 to move back and forth, causing the bristles on its surface to brush the surface of the filter screen 10. The tea leaves will then re-enter the cylinder 1 through the air outlet 9 and fall into the collection basket 13.

[0021] Reference Figure 2 and Figure 6 The collection assembly includes a collection basket 13 fixedly connected to the bottom side of the cylinder 1. A baffle plate 14 is fixedly connected to the inner wall of the collection basket 13. A discharge cover 15 equipped with a lock is rotatably connected to the bottom side of the collection basket 13. The baffle plate 14 is in an inclined state and its front end is bent. Specifically, when tea leaves fall through the inclined baffle plate 14 in the collection basket 13 to the bottom of the baffle plate 14, the airflow entering the collection basket 13 will be guided along the bottom trajectory of the baffle plate 14, so that the tea leaves are blocked by the end of the baffle plate 14, making it difficult for them to leave the inside of the collection basket 13, and thus they are collected. The tea leaves can be removed by opening the discharge cover 15 on the bottom of the collection basket 13.

[0022] Working Principle: First, the tea leaves to be crushed and dried are placed into the drum 2 inside the cylinder 1. Then, the cylinder cover 17 is closed and locked. The motor is then started to drive the rotating shaft 3 to rotate. The rotating shaft 3 rotates through a sun gear 6 on its outer wall, meshing with multiple planetary gears 7. The planetary gears 7 synchronously mesh with the gear ring 5 connected to the drum 2, causing the rotating shaft 3 and drum 2 to rotate in opposite directions, creating a speed difference. The drum 2 rotates at a slower speed to prevent over-crushing of the tea leaves. The rotating shaft 3 drives the connected crushing belt 4 to crush the tea leaves inside the drum 2. Simultaneously, hot air enters the cylinder 1 through the air inlet 16 and comes into contact with the tea leaves in the drum 2. As the drum 2 tumbles the tea leaves, they are fully exposed to the hot air, causing moisture to evaporate. The tea leaves are then discharged through the air outlet 9 along with the hot air. During the process of the hot air exiting through the air outlet 9, the crushed tea leaves... The slag will pass through the drum 2 and arrive at the air outlet 9 along with the hot air. It will be intercepted by the filter screen 10 on the inner wall of the air outlet 9, causing the slag to accumulate on the filter screen 10. The rotating shaft 3 drives the reciprocating screw 12 to rotate through the synchronous belt and synchronous pulley. The reciprocating screw 12 drives the brush 11 to move back and forth, causing the bristles on its surface to brush the surface of the filter screen 10. The slag will then re-enter the drum 1 through the air outlet 9 and fall into the collection basket 13. It will slide down the inclined baffle plate 14 in the collection basket 13 to the bottom side of the baffle plate 14. The airflow entering the collection basket 13 will be guided along the bottom track of the baffle plate 14, so that the slag is blocked by the end of the baffle plate 14 and is not easy to leave the inside of the collection basket 13, thus being collected. After the crushing and drying are completed, the motor operation is stopped, the drum cover 17 is opened, the dried and crushed tea leaves are taken out, and the discharge cover 15 on the bottom side of the collection basket 13 is opened to take out the slag waste.

[0023] It is worth noting that the circuits, protection systems, and motors involved in the above embodiments all adopt corresponding existing technologies based on actual conditions, and therefore will not be described in detail in the embodiments of this application.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
