[0023] In order to make the technical scheme and advantages of the utility model more clear and obvious, the utility model is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0024] The utility model provides a technical scheme: refer to Figure 1 Figure 7 The utility model discloses a fresh tea leaf dewatering device, including conveyor 1 and gas heater 2, gas heater 2 is fixedly installed on the top side of the drying channel of conveyor 1, is equipped with gas injection mechanism 4 on the shell of conveyor 1, is equipped with storage assembly 3 on the conveying belt of conveyor 1;

[0025] Storage assembly 3 includes storage box 31, and the box wall of storage box 31 is meshed, is equipped with mesh plate 32 in the top opening of storage box 31, and the outer peripheral wall of mesh plate 32 is in contact with the inner wall of storage box 31, and limiting mechanism 33 is equipped in storage box 31.

[0026] ​In the improved fresh tea dehydration device, the operator first puts a proper amount of tea into the storage box 31, and then puts the mesh plate 32 into the storage box 31. At this time, the mesh plate 32 is always located at a specific position in the storage box 31 due to the constraint of the limiting mechanism 33 on the mesh plate 32, and there is a large gap between the mesh plate 32 and the tea. After the filling of the tea in a plurality of storage boxes 31 is completed, the operator puts the tea on the conveying belt of the conveyor 1 in sequence, and starts the conveyor 1 to push the storage boxes 31 into the drying channel of the conveyor 1 in sequence. At the same time, the air heated by the gas heating device is quickly injected into the storage boxes 31 through the air injection mechanism 4, and the tea in the storage boxes 31 is blown in sequence. Through the airflow, the fresh tea in the storage boxes 31 is blown up, and the tea is turned over at the same time, so that the tea is in full contact with the hot airflow. Finally, through the heat exchange between the hot airflow and the tea, the heating and dehydration treatment is completed.

[0027] In further preferable embodiments of the present application, as shown in Figure 1 and Figure 2 , a plurality of limiting rods 5 with semicircular cross-section are fixedly arranged on the conveying belt of the conveyor 1, and the spacing between adjacent two limiting rods 5 is equal.

[0028] In the present embodiment, when the storage box 31 is placed on the conveying belt of the conveyor 1, the storage box 31 is directly placed on the adjacent two limiting rods 331, so that the friction between the storage box 31 and the conveying belt of the conveyor 1 is increased through the mutual resistance between the limiting rods 331 and the storage box 31, thereby avoiding the pushing force applied to the storage box 31 by the airflow when the airflow passes through the storage box 31, which causes the storage box 31 to slip and affects the operation of the device.

[0029] In further preferable embodiments of the present application, as shown in Figure 1 and Figure 3 , the air injection mechanism 4 comprises a plurality of flow guide pipes 41, and the plurality of flow guide pipes 41 are arranged in the conveying belt of the conveyor 1. The two ends of each flow guide pipe 41 are fixedly penetrated through the shell of the conveyor 1. The top end of the flow guide pipe 41 is provided with an expanded port, and the top end of the flow guide pipe 41 is in contact with the conveying belt of the conveyor 1. The front side of the conveyor 1 is provided with a flow divider 42, and a plurality of exhaust ends of the flow divider 42 are fixedly penetrated through the pipe wall of the corresponding flow guide pipe 41. The air inlet end of the flow divider 42 is in communication with the exhaust end of the gas heater 2.

[0030] In the embodiment, the gas heated by the gas heater 2 is injected into the guide pipes 41 through the shunt pipe 42, and the gas injected into the guide pipes 41 first fills the guide pipes 41 and is discharged from the top opening of the guide pipes 41 in a linear flow state, and the gas flow discharged from the guide pipes 41 flows upwards through the holes of the conveying belt of the conveyor 1 and flows back into the gas heater 2 at the top side of the drying tunnel of the conveyor 1 for heat recovery of the gas.

[0031] In further preferable embodiments of the present application, as shown in Figure 1 , Figure 4 and Figure 5 , the limiting mechanism 33 comprises two limiting strips 331, the left and right sidewalls of the mesh plate 32 are arc-shaped, the two limiting strips 331 are oppositely arranged at the bottom side of the mesh plate 32, and each limiting strip 331 is fixedly connected with the inner wall of the storage box 31, the bottom side of the limiting strip 331 is coplanar with the bottom side of the mesh plate 32, the top side of the limiting strip 331 is arc-shaped and in contact with the arc surface of the mesh plate 32, and a handle 336 is fixedly arranged at the middle position of the top side of the mesh plate 32.

[0032] In the embodiment, when the mesh plate 32 is inserted into the opening of the storage box 31, the limiting strips 331 limit the mesh plate 32, so that there is enough gap between the mesh plate 32 and the inner bottom wall of the storage box 31 for the floating of the fresh tea leaves.

[0033] In further preferable embodiments of the present application, as shown in Figure 4 , Figure 6 the inner wall of the storage box 31 oppositely has a plurality of storage grooves 332, the storage grooves 332 are provided with elastic sheets 333 in a semi-annular cross-sectional shape, the upper and lower ends of the elastic sheets 333 are fixedly connected with the inner walls of the corresponding storage grooves 332, and the outer arc wall of the elastic sheet 333 is in contact with the arc surface of the top side of the mesh plate 32.

[0034] In the embodiment, when the mesh plate 32 is inserted into the opening of the storage box 31, the arc surfaces on both sides of the mesh plate 32 abut against the elastic sheets 333, the elastic sheets 333 can be pressed into the storage grooves 332 along the outer arc surfaces of the elastic sheets 333, and the mesh plate 32 can directly move below the elastic sheets 333 under the condition of a large external force, until the mesh plate 32 abuts against the limiting strips 331, and after the mesh plate 32 abuts against the limiting strips 331, the elastic sheets 333 are automatically ejected from the storage grooves due to the reset of the elastic sheets, and abut against the arc surfaces on both sides of the mesh plate 32, cooperating with the support and limitation of the limiting strips 331 on the mesh plate 32, so that the position of the mesh plate 32 in the storage box 31 remains stable under the condition of no large external force, and the assembly operation between the mesh plate 32 and the storage box 31 is simple and does not require other operations by the operator.

[0035] In further preferable embodiments of the present application, as shown in Figure 7 A plurality of first round rods 334 and a plurality of second round rods 335 are fixedly arranged at the middle position of the storage box 31, and the first round rods 334 and the second round rods 335 are integrally cast in a cross shape.

[0036] In the present embodiment, during the floating process of the tea leaves in the storage box 31, when the tea leaves move to the position of the first round rods 334 and the second round rods 335, the tea leaves can change the inclination angle along the outer arc surface of the first round rods 334 and the outer arc surface of the second round rods 335 due to the mutual interference of the tea leaves with the first round rods 334 and the second round rods 335, thereby turning the tea leaves to a certain extent, and the tea leaves adhered together can be blown apart by the airflow when the angle of the tea leaves changes, so that the hot airflow can fully contact the tea leaves.

[0037] Working principle: when the improved fresh tea leaf dewatering device is used, the operator first pulls the mesh plate 32 out of the storage box 31 by the handle 336, and due to the mutual interference of the arc surfaces on both sides of the mesh plate 32 with the elastic pieces 333, the elastic pieces 333 can be pressed into the storage grooves 332 along the outer arc surfaces of the elastic pieces 333, thereby automatically releasing the constraint and limiting state of the mesh plate 32, so that the mesh plate 32 can be directly pulled out of the storage box 31 under the action of a large external force;

[0038] After the operator pulls the mesh plate 32 out of the storage box 31, the operator inserts an appropriate amount of tea leaves into the storage box 31 from the opening of the storage box 31, and then inserts the mesh plate 32 into the storage box 31, at which time due to the mutual interference of the arc surfaces on both sides of the mesh plate 32 with the elastic pieces 333, the elastic pieces 333 can be pressed into the storage grooves 332 along the outer arc surfaces of the elastic pieces 333, thereby enabling the mesh plate 32 to directly move below the elastic pieces 333 under the action of a large external force, until the mesh plate 32 interferes with the limiting strips 331, and after the mesh plate 32 interferes with the limiting strips 331, the elastic pieces 333 are automatically ejected from the storage grooves due to the reset of the elastic pieces, and interfere with the arc surfaces on both sides of the mesh plate 32, which cooperates with the support and limiting of the limiting strips 331 to the mesh plate 32, so that the position of the mesh plate 32 in the storage box 31 remains stable under the condition of not being subjected to a large external force;

[0039] According to the above, the fresh tea leaves are sequentially inserted into the plurality of storage boxes 31, and then the operator starts the conveyor 1 and the gas heater 2, the gas heater 2 injects the heated gas into the plurality of guide pipes 41 through the shunt pipe 42, and since the amount of gas discharged at the guide pipe 41 is limited, the gas injected into the guide pipe 41 first fills the guide pipe 41 and is discharged from the top opening of the guide pipe 41 in a linear airflow state, and the airflow discharged from the guide pipe 41 flows upward through the holes of the conveyor 1 conveying belt and flows back into the gas heater 2 from the top side of the drying tunnel of the conveyor 1, and the heat of the gas is recovered;

[0040] With the operation of the conveyor 1, the storage boxes 31 are sequentially pushed into the drying tunnel of the conveyor 1 and sequentially pass above the exhaust ports of the guide pipes 41, the gas discharged from the guide pipes 41 passes through the holes of the storage boxes 31 and sequentially blows the tea leaves in the storage boxes 31 upward, so that the tea leaves float upward, and when the tea leaves move to the positions of the first circular rod 334 and the second circular rod 335, the tea leaves can change the inclination angle along the outer arc surface of the first circular rod 334 and the outer arc surface of the second circular rod 335 due to the mutual interference of the first circular rod 334 and the second circular rod 335, thereby turning the tea leaves to a certain extent, the floating tea leaves are in full contact with the hot airflow, and finally the heating and dewatering treatment is completed through the heat exchange when the hot airflow contacts the tea leaves, and when the tea leaves move away from the exhaust ports of the guide pipes 41, the tea leaves slowly float down due to the weakening of the airflow, avoiding that the tea leaves are always attached to the screen plate 32 due to the blowing of the airflow, affecting the airflow passing through the storage boxes 31.

[0041] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection required by the present application is defined by the appended claims and their equivalents.
