However, the device can only solve one aspect of the problem, and there are other problems that may cause the tea leaves to break during the working process. Summary of the invention

[0005] The purpose of the utility model is to provide a tea drying device which can reduce the breakage of tea leaves, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A tea drying device capable of reducing tea breakage comprises a bracket, a box body fixedly connected above the bracket, a motor fixedly connected outside the box body, an air inlet is provided on the side of the box body close to the motor, a drying component for drying is connected inside the box body, a heating component for heating air is connected inside the box body, a feed inlet and a feed outlet are respectively provided above and below the box body, a cover plate is rotatably connected at the feed inlet and the discharge port, a handle is fixedly connected on the cover plate, and an annular groove is provided inside the box body.

[0008] When the tea leaves need to be dried, pull the handle to open the cover, then put the tea leaves to be dried into the drying component, start the motor, and the motor will drive the drying component to work. At the same time, the heating component will also start, sucking in the air outside the box, and then heating the air to the required temperature through the heating step, and then passing it into the box. At this time, the moisture contained in the tea leaves will be carried away and discharged by the air, thereby achieving the purpose of drying the tea leaves. After the tea leaves are dried, pull the handle to open the cover at the bottom of the box, and then open the drying component, so that all the tea leaves in the drying component can be collected, making collection more convenient and improving work efficiency.

[0009] A further improvement of the technical solution of the utility model is that the drying component includes a driving gear, which is fixedly connected to the output end of the motor, a plurality of driven gears are evenly arranged on the outside of the driving gear, the driven gears are respectively meshed with the driving gear, a gear ring is arranged on the outside of the driven gear, the gear ring is fixedly connected to the box body, the gear ring is meshed with the driven gear, a support rod is fixedly connected to the driven gear, the support rod is slidably connected to the annular groove, a screen box is fixedly connected to one end of the support rod away from the driven gear, screens are rotatably connected to both sides of the screen box, bolts are threadedly connected to the screen and one side of the screen box, the screen is fixed to the screen box by bolts, and the circular plate in the center of the annular groove is fixedly connected to the driving gear.

[0010] The above technical solution is adopted. In this solution, when the drying component is working, the motor starts and drives the driving gear fixedly connected to its output end to rotate. The driving gear will drive several driven gears meshing with it to rotate. Because the driven gear is meshed with the ring gear and the ring gear is fixedly connected to the box body, the driven gear not only rotates on its own but also revolves around the driving gear. In this way, the drying component can fully contact the tea leaves with hot air during the drying process, improve the drying efficiency of the drying component, and the tea leaves are not easy to break during the drying process. Screens are arranged on both sides of the screen box so that when the drying device stops, the tea leaves can be easily taken out no matter which side is on which side, which greatly improves the working efficiency of the device.

[0011] A further improvement of the technical solution of the utility model is that the heating component includes an air intake duct and a ventilation duct, an air intake fan is fixedly connected inside the air intake duct, the air intake fan is fixedly connected to the air intake duct, an electric heating wire is provided in the air intake duct, the electric heating wire is fixedly connected to the air intake duct, a filter is provided at the air inlet, and the filter is fixedly connected to the box.

[0012] The above technical solution is adopted. In this solution, when the heating component starts to work, the air intake fan rotates to inhale the air outside the box, which is heated by the electric heating wire and converted into hot air and transported into the box. Then the tea leaves in the screen box are dried. The hot air absorbs the water vapor contained in the tea leaves in the screen box, and then is discharged to the air inlet through the ventilation pipe for reuse. Because the discharged gas still has a higher temperature, it can save resources and costs, reduce the time required for drying, improve work efficiency, and reduce the temperature difference in the box, so that the tea leaves are not easily broken during the drying process. A filter is set at the air inlet to intercept impurities in the air, thereby ensuring that the tea leaves are not contaminated during the drying process.

[0013] A further improvement of the technical solution of the utility model is that an intake air temperature sensor is fixedly connected to one end of the intake pipe away from the air inlet, and a conical opening is provided at one end of the intake pipe away from the air inlet.

[0014] The above-mentioned technical scheme is adopted, in which an intake temperature sensor is fixedly connected to the end of the air intake pipe away from the air inlet to detect the temperature of the gas after being heated by the heating wire, so as to be used to timely adjust the temperature of the heating wire, thereby improving work efficiency. The conical mouth is provided at the end of the air intake pipe away from the air inlet because the gas flows faster when it is transported in the pipe. The conical mouth can slow down the flow speed of the gas when it flows out of the air intake pipe, thereby preventing the tea leaves from being broken due to excessive wind speed.

[0015] A further improvement of the technical solution of the utility model is that an elastic baffle is rotatably connected to one end of the ventilation pipe close to the air inlet pipe.

[0016] The above-mentioned technical solution is adopted, in which an elastic baffle is rotatably connected to one end of the ventilation duct close to the air inlet duct to achieve a one-way conduction effect. When the gas pressure in the box is sufficient, the elastic baffle opens under the action of pressure to block the air inlet. At this time, the gas inside the box begins to circulate internally, which greatly saves costs and reduces the time required for drying.

[0017] A further improvement of the technical solution of the utility model is that half of the width of the screen box is smaller than the distance between any two driven gears.

[0018] The above technical solution is adopted, in which half of the width of the screen box is set to be smaller than the distance between any two driven gears in order to prevent the screen boxes from colliding with each other during the rotation process and causing the tea leaves to be broken, thereby protecting the device and the tea leaves at the same time and reducing the breakage rate of the tea leaves, thereby improving the working efficiency of the device.

[0019] A further improvement of the technical solution of the utility model is that a water vapor absorption device is fixedly connected to the inlet of the ventilation pipe.

[0020] The above technical solution is adopted, in which a water vapor absorption device is fixedly connected to the inlet of the ventilation duct to absorb the water vapor absorbed by the tea leaves themselves in the gas, so that the exhausted hot air can be reused, which greatly saves the heating cost, and the water vapor absorption device is arranged at the inlet of the ventilation duct to achieve the effect of easy replacement.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model provides a tea drying device capable of reducing the breakage of tea leaves. An air intake temperature sensor is fixedly connected to one end of the air intake duct away from the air intake port, which can detect the temperature of the gas heated by the electric heating wire, so as to timely adjust the temperature of the electric heating wire, thereby improving the working efficiency. A conical mouth is provided at one end of the air intake duct away from the air intake port because the gas flows faster when it is transported in the duct. The conical mouth can slow down the flow speed of the gas when it flows out of the air intake duct, thereby preventing the tea leaves from being broken due to excessive wind speed.

[0023] 2. The utility model provides a tea drying device which can reduce the breakage of tea leaves. An elastic baffle is rotatably connected to one end of the ventilation duct close to the air inlet duct to achieve a one-way conduction effect. When the gas pressure in the box is sufficient, the elastic baffle opens under the action of pressure to block the air inlet. At this time, the gas inside the box begins to circulate internally, which greatly saves costs and reduces the time required for drying.

[0024] 3. The utility model provides a tea drying device that can reduce the breakage of tea leaves. The half of the width of the screen box is set to be smaller than the distance between any two driven gears in order to prevent the screen boxes from colliding with each other during the rotation process and causing the tea leaves to break. This can protect the device and the tea leaves at the same time, reduce the breakage rate of the tea leaves, and improve the working efficiency of the device.

[0025] 3. The utility model provides a tea drying device which can reduce the breakage of tea leaves. A water vapor absorption device is fixedly connected to the inlet of the ventilation duct to absorb the water vapor absorbed by the tea leaves themselves in the gas, so that the exhausted hot air can be reused, which greatly saves the heating cost. In addition, the water vapor absorption device is arranged at the inlet of the ventilation duct to facilitate replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] When the drying part is working, the motor 3 starts, driving the driving gear 10 fixedly connected to its output end to rotate, and the driving gear 10 will drive several driven gears 11 meshed with it to rotate, because the driven gear 11 is meshed with the ring gear 12 and the ring gear 12 is fixedly connected to the housing 2, so the driven gear 11 not only rotates on its own, but also revolves around the driving gear 10, so that the drying part can make the tea leaves fully contact with the hot air during the drying process, improve the drying efficiency of the drying part, and the tea leaves are not easy to break during the drying process. Screens 15 are respectively arranged on both sides of the screen box 14 so that when the drying device stops, no matter which side it is, the tea leaves can be easily taken out, which greatly improves the working efficiency of the device.

[0050] like Figure 2 As shown, based on Example 1, the utility model provides a technical solution: preferably, half of the width of the screen box 14 is smaller than the distance between any two driven gears 11.

[0051] In this embodiment, half of the width of the screen box 14 is set to be smaller than the distance between any two driven gears 11 in order to prevent the screen boxes 14 from colliding with each other during the rotation process and causing the tea leaves to be broken, thereby protecting the device and the tea leaves at the same time and reducing the breakage rate of the tea leaves, thereby improving the working efficiency of the device.

[0052] The working principle of the tea drying device which can reduce the breakage of tea leaves will be described in detail below.

[0053] like Figure 1-5As shown, when it is necessary to dry tea leaves, pull the handle 8 to open the cover 7, then put the tea leaves to be dried into the drying component, start the motor 3, at this time, the motor 3 will drive the drying component to work, and at the same time, the heating component is also started at the same time, sucking in the air outside the box 2, and then heating the air to the required temperature through the heating step, and then passing it into the box 2. At this time, the moisture contained in the tea leaves will be taken away and discharged by the air, thereby achieving the purpose of drying the tea leaves. After the tea leaves are dried, pull the handle 8 to open the cover 7 at the bottom of the box 2, and then open the drying component, so that all the tea leaves in the drying component can be collected, making collection more convenient and improving work efficiency. When the drying part is working, the motor 3 starts, driving the driving gear 10 fixedly connected to its output end to rotate, and the driving gear 10 will drive several driven gears 11 meshed with it to rotate, because the driven gear 11 is meshed with the ring gear 12 and the ring gear 12 is fixedly connected to the housing 2, so the driven gear 11 not only rotates on its own, but also revolves around the driving gear 10, so that the drying part can make the tea leaves fully contact with the hot air during the drying process, improve the drying efficiency of the drying part, and the tea leaves are not easy to break during the drying process. Screens 15 are respectively arranged on both sides of the screen box 14 so that when the drying device stops, no matter which side it is, the tea leaves can be easily taken out, which greatly improves the working efficiency of the device. When the heating component starts to work, the air intake fan 19 rotates to inhale the air outside the box 2, which is heated by the electric heating wire 20 and turned into hot air and transported to the box 2, and then the tea leaves in the screen box 14 are dried. The hot air absorbs the water vapor contained in the tea leaves in the screen box 14, and then is discharged to the air inlet 4 through the ventilation pipe 18 for reuse. Because the discharged gas still has a higher temperature, it can save resources and costs, reduce the time required for drying, improve work efficiency, and reduce the temperature difference in the box 2, so that the tea leaves are not easily broken during the drying process. A filter 21 is provided at the air inlet 4 to intercept impurities in the air, thereby ensuring that the tea leaves are not contaminated during the drying process. An intake temperature sensor 22 is fixedly connected to the end of the intake duct 17 away from the air inlet 4 to detect the temperature of the gas heated by the electric heating wire 20, so as to timely adjust the temperature of the electric heating wire 20 to improve work efficiency. The conical mouth 23 is set at the end of the intake duct 17 away from the air inlet 4 because the gas flows faster when it is transported in the duct. The conical mouth 23 can slow down the flow of the gas when it flows out of the intake duct 17 to prevent the tea leaves from being broken due to excessive wind speed. An elastic baffle 24 is rotatably connected to the end of the ventilation duct 18 close to the intake duct 17 to achieve a one-way conduction effect. When the gas pressure in the box 2 is sufficient, the elastic baffle 24 opens under the action of pressure to block the air inlet 4. At this time, the gas inside the box 2 begins to circulate internally, which greatly saves costs and reduces the time required for drying.At the same time, a water vapor absorption device 25 is fixedly connected at the entrance of the ventilation duct 18 to absorb the water vapor absorbed by the tea leaves themselves in the gas, so that the discharged hot air can be reused, which greatly saves the heating cost. In addition, the water vapor absorption device 25 is arranged at the entrance of the ventilation duct 18 to achieve the effect of easy replacement. The half of the width of the screen box 14 is set to be smaller than the spacing between any two driven gears 11 to prevent the screen boxes 14 from colliding with each other during the rotation process and causing the tea leaves to break. In this way, the device and the tea leaves can be protected at the same time, and the breakage rate of the tea leaves can be reduced. The working efficiency of the device is improved.

[0054] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
