DETAILED DESCRIPTION

[0021] In order to make the technical solution and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] The utility model provides a technical solution: Figure 1-5 The utility model discloses a tea drying machine, including a shell 1 and a gas heating device 2. A drying mechanism 3 is arranged in the shell 1. The drying mechanism 3 includes a mesh cylinder 31. The mesh cylinder 31 is rotatably installed in the shell 1 through a bearing. The gas heating device 2 is fixedly installed at one end of the bottom side of the shell 1. An exhaust member 32 is arranged on the bottom side of the mesh cylinder 31. A gear driver 33 is arranged at one end of the shell 1, and a driving end of the gear driver 33 is fixedly sleeved on the outer peripheral side of the mesh cylinder 31. A hot air reflux mechanism 4 is arranged in the mesh cylinder 31.

[0023] In this embodiment, when the improved tea drying machine is used, the hot air reflux mechanism 4 continuously extracts the gas in the housing 1 and heats it through the gas heating device 2, and then the heated gas is divided into a plurality of small air streams through the exhaust member 32 and blown on the mesh cylinder 31. The small air streams pass through the holes of the mesh cylinder 31 and blow on the tea leaves in the mesh cylinder 31, so that the heated hot air directly contacts the tea leaves in the mesh cylinder 31 to dry the tea leaves, and pushes the tea leaves at the bottom upward to assist in the turning of the tea leaves, and when the air stream passes through the holes of the mesh cylinder 31, the tea leaves inserted in the holes of the mesh cylinder 31 can be pushed out;

[0024] When the airflow flows out from the gaps between the tea leaves, the airflow can simultaneously carry the tea leaves and remove them from the mesh tube 31 together with the tea leaves, and the tea leaves are intercepted and stored at a specific position by the hot air reflux mechanism 4, thereby cleaning the tea leaves and collecting the tea leaves at the same time.

[0025] In a further preferred embodiment of the present invention, Figure 2 As shown, a baffle 34 is rotatably mounted in the opening at one end of the net cylinder 31 through a bearing, and the baffle 34 is fixedly connected to the housing 1 through a bracket, and a cover 35 is provided at the other end of the net cylinder 31, and a threaded end of the cover 35 is inserted into the opening at the other end of the net cylinder 31 and is threadedly connected to the inner wall of the opening at the other end of the net cylinder 31;

[0026] In this embodiment, when loading tea leaves, the operator screws the cover 35 out of the mesh cylinder 31, and then stuffs an appropriate amount of tea leaves into the mesh cylinder 31 from the opening of the mesh cylinder 31, and then screws the cover 35 back into the opening of the mesh cylinder 31, and the tea leaves loading operation is completed; the rotatable installation of the baffle 34 prevents the baffle 34 from rotating with the mesh cylinder 31, thereby making the support and limitation of the baffle 34 on the fixed cylinder 41 more stable.

[0027] In a further preferred embodiment of the present invention, Figure 2 and Figure 3 As shown, the exhaust member 32 includes a support plate 321 in the shape of a semicircular tube, both ends of the support plate 321 are fixedly connected to the inner wall of the shell 1, and the inner ring wall of the support plate 321 is slidably connected to the outer peripheral wall of the net tube 31, the interior of the support plate 321 is hollow, and a plurality of exhaust holes 322 are opened on the inner ring wall of the support plate 321, and the exhaust end of the gas heating device 2 is inserted into the support plate 321 and fixedly connected to the support plate 321;

[0028] In this embodiment, the gas discharged from the gas heating device 2 is directly injected into the support plate 321. Since the amount of gas discharged from the exhaust hole 322 is limited, the gas injected into the support plate 321 quickly fills the support plate 321 and forms a high-pressure chamber in the support plate 321. At the same time, a large pressure difference is generated at both ends of the exhaust hole 322, so that the heated gas is quickly discharged from the plurality of exhaust holes 322, and blows onto the tea leaves in the mesh tube 31 through the holes of the mesh tube 31, assisting the tea leaves in turning over, and simultaneously drying the tea leaves. At the same time, the hot air blends with the gas in the outer shell 1, so that a closed space with a higher temperature is formed in the outer shell 1, thereby assisting the drying of the tea leaves through the high-temperature space, and the drying rate of the tea leaves is faster.

[0029] In a further preferred embodiment of the present invention, Figure 2As shown, the hot air reflow mechanism 4 includes a fixed cylinder 41, which is fixedly installed through the center of the baffle 34, and the fixed cylinder 41 is transversely arranged at the axis position in the net cylinder 31, and a plurality of circular holes 42 are opened in a circular array on the outer peripheral wall of the fixed cylinder 41;

[0030] In this embodiment, when the hot air flows out from the gaps in the tea leaves, it carries the tea leaves and flows into the fixed tube 41 through the circular hole 42, and the airflow is guided out of the outer shell 1 by the fixed tube 41, and the airflow carrying the tea leaves is guided out of the mesh tube 31, so as to prevent the tea leaves from being re-attached to the inner wall of the mesh tube 31 when the airflow carrying the tea leaves passes through the holes in the mesh tube 31.

[0031] In a further preferred embodiment of the present invention, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a box cover 43 is fixedly installed on the other end of the bottom side of the shell 1, and a box body 44 is provided on the bottom end of the box cover 43 through a snap-fit ​​fixing sleeve, an air pump 45 is fixedly installed on the other side of the box cover 43, and the air inlet end of the air pump 45 is inserted into the box cover 43 and fixedly connected to the box cover 43, and the exhaust end of the air pump 45 is communicated with the air inlet end of the gas heating device 2 through a connecting pipe 410, a filter plate 46 is fixedly installed in the box cover 43, and the air inlet end of the air pump 45 is located above one end of the filter plate 46, an air inlet hole 47 is opened on the right side of the box body 44, and the exhaust end of the air inlet hole 47 is located below the other end of the filter plate 46, a guide shell 48 is fixedly installed at the position of the right side of the box cover 43 corresponding to the air inlet hole 47, and the interior of the guide shell 48 is communicated with the interior of the air inlet hole 47, and the interior of the guide shell 48 is communicated with the interior of the fixed cylinder 41 through an air guide pipe 49;

[0032] In this embodiment, when the mesh cylinder 31 rotates to turn the tea leaves, the air pump 45 starts to continuously extract the gas in the box cover 43, so that a negative pressure cavity is continuously formed in the box cover 43 and the box body 44, and then the gas in the fixed tube is continuously sucked in through the guide tube, so that a negative pressure cavity is continuously formed in the fixed tube. Due to the large pressure difference at both ends of the circular hole 42, the gas in the mesh cylinder 31 continuously passes through the circular hole 42 into the fixed tube to replenish the lost gas in the fixed tube, and absorbs the hot air in the outer shell 1 for circulating heating treatment, thereby greatly reducing the electric energy consumed by the gas heating device 2 when heating the gas, thereby reducing the energy consumption of the device.

[0033] In a further preferred embodiment of the present invention, Figure 5 As shown, the filter plate 46 is arranged in an inclined shape, one end of the air inlet hole 47 is arranged in a flared shape, and the other end of the air inlet hole 47 is arranged in a rectangular shape, and the inner top side of the exhaust end of the air inlet hole 47 is coplanar with the bottom side of the filter plate 46;

[0034] In the present embodiment, when the gas carrying tea leaves is discharged from the air guide pipe 49, it is directly discharged into the guide shell 48. At this time, due to the limited exhaust volume at the air inlet 47, the gas flowing into the guide shell 48 quickly fills the guide shell 48, and causes a large pressure difference at both ends of the air inlet 47. The gas in the guide shell 48 passes through the air inlet 47 and forms a rectangular airflow that blows on the filter plate 46, and slides along the inclined inner wall of the bottom side of the filter plate 46, thereby blowing off the tea leaves attached to the bottom side of the filter plate 46, and the tea leaves are intercepted by the filter plate 46 and retained in the box 44 for storage.

[0035] Working principle: When the improved tea drying machine is used, the operator first twists the cover 35 out of the net cylinder 31, then inserts a proper amount of tea leaves into the net cylinder 31 through the opening of the net cylinder 31, and then twists the cover 35 back into the opening of the net cylinder 31, and the tea feeding operation is completed;

[0036] After the tea leaves are loaded, the gear driver 33 drives the net cylinder 31 to rotate continuously, thereby quickly turning the tea leaves in the net cylinder 31;

[0037] At the same time, the operator starts the air pump 45 to continuously extract the gas in the box cover 43, and injects the gas into the gas heating device 2 for gas heating treatment, and then the heated gas is quickly injected into the support plate 321. Since the amount of gas discharged from the exhaust hole 322 is limited, the gas injected into the support plate 321 quickly fills the support plate 321 and forms a high-pressure cavity in the support plate 321, and at the same time, a large pressure difference is generated at both ends of the exhaust hole 322, so that the heated gas is quickly discharged from the exhaust holes 322, and passes through the holes of the net tube 31 to blow on the tea leaves in the net tube 31, assisting the tea leaves in the tea leaf turning treatment, and at the same time, a closed space with a higher temperature is formed in the shell 1, and the tea leaves are dried by the heated airflow;

[0038] As the gas in the box cover 43 is lost, a negative pressure cavity is continuously formed in the box cover 43 and the box body 44, and the gas in the fixed cylinder 41 is continuously sucked in through the guide tube, so that a negative pressure cavity is continuously formed in the fixed cylinder 41. Due to the large pressure difference between the two ends of the circular hole 42, the gas in the net cylinder 31 continuously passes through the circular hole 42 into the fixed cylinder 41 to replenish the lost gas in the fixed cylinder 41.

[0039] When the above-mentioned airflow passes through the holes of the mesh tube 31, the tea leaves inserted in the holes of the mesh can be pushed out, and when the airflow passes through the gaps between the tea leaves, the tea leaves in the tea leaves can be brought into the air guide pipe 49 by the airflow, and then introduced into the guide shell 48 by the air guide pipe 49. At this time, due to the limited exhaust volume at the air inlet 47, the gas flowing into the guide shell 48 quickly fills the guide shell 48, and a large pressure difference is generated at both ends of the air inlet 47. The gas in the guide shell 48 passes through the air inlet 47 and forms a rectangular airflow that blows on the filter plate 46, and slides along the inclined inner wall of the bottom side of the filter plate 46, thereby blowing off the tea leaves attached to the bottom side of the filter plate 46, and due to the interception of the filter plate 46, the tea leaves are retained and stored in the box body 44, the operation of the device is intermittently stopped, and the buckle between the box body 44 and the box cover 43 is released, so that the box body 44 can be pulled off the box cover 43, so that the collected tea leaves can be moved to a specific position for dumping through the movement of the box body 44.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected.
