Description

Technical Field

[0001] The utility model relates to the field of tea production, in particular to a feeding and conveying device of a tea stir-frying machine. Background Art

[0002] In the tea production process, in order to remove the active enzymes in tea and evaporate the excess moisture in tea raw materials, people will perform a stir-frying operation on the tea raw materials. The stir-frying of tea has gradually developed from the most primitive sun drying and drying (making tea cakes for preservation) to the current pan-frying stir-frying, hot air stir-frying, steam stir-frying, microwave stir-frying, and steam-hot air hybrid stir-frying. Among them, pan-frying stir-frying has the widest range of applications. With the development of industrialization, the tea-frying equipment has gradually developed into an automated structure. In order to provide raw materials for the stir-frying machine faster, a corresponding conveying device needs to be installed at the feeding port of the tea stir-frying machine.

[0003] The existing feeding and conveying device of a tea stir-frying machine mainly blows by wind. For example, a feeding and conveying device of a tea stir-frying machine shown in the Chinese patent public number CN220222490U blows tea raw materials from the fixed branch pipe of the feeding branch pipe through a blower device. After the tea is blown from the fixed branch pipe into the discharge pipe, the discharge pipe is connected to the inside of the tea stir-frying machine to continuously input tea into the stir-frying machine on a small scale (ensuring the uniform input of tea), so that the tea can be fully heated and avoid the situation of uneven local heating.

[0004] This feeding and conveying device of a tea stir-frying machine can greatly improve the conveying efficiency of tea, thereby improving the production efficiency of tea production. However, when facing tea stir-frying machines of different models, since the inlet heights of different types of tea stir-frying machines are different, the height of the discharge pipe of this device cannot be adjusted in time according to the actual situation (the height of the fixed branch pipe of this device is fixed by a bracket), thus affecting the production efficiency. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is that the height of the fixed branch pipe of the existing feeding and conveying device of a tea stir-frying machine cannot be adjusted, so that the height of the discharge pipe cannot be adjusted according to the actual situation.

[0006] To solve the above technical problems, the technical solution provided by the present utility model is as follows: a feeding and conveying device for a tea withering machine, including a conveying frame, above which there are successively sleeved a blowing device, a blanking branch pipe, a fixed branch pipe and a discharge pipe. Below the fixed branch pipe, there is a height adjusting device. Between the blanking branch pipe and the fixed branch pipe, there is a bendable pipe structure. The height adjusting device includes a telescopic device above the conveying frame and a fixing plate below the fixed branch pipe. Above the fixing plate, there are several detachable fixing clips sleeved on the outer wall of the fixed branch pipe. The bendable pipe structure includes a stretchable plastic pipe sleeved on the feed inlet of the fixed branch pipe and the discharge outlet of the blanking branch pipe, and a composite joint structure located on the outer wall of the stretchable plastic pipe.

[0007] As an improvement, the composite joint structure is connected to the stretchable plastic pipe through sealant.

[0008] As an improvement, the angle of the blanking port of the blanking branch pipe is perpendicular to the discharge outlet of the main pipe of the blanking branch pipe.

[0009] As an improvement, the fixing plate is connected to the detachable fixing clip through a bolt structure, and the output shaft of the height adjusting device is connected to the bottom surface of the fixing plate by welding.

[0010] As an improvement, on one side of the fixed branch pipe, there is an auxiliary blowing device. Inside the fixed branch pipe, there is a blowing partition layer, and on the inner wall of the fixed branch pipe, there are several one-way inclined air blowing ports.

[0011] As an improvement, the auxiliary blowing device is connected to the air inlet of the blowing partition layer through a blowing hose.

[0012] As an improvement, on one side of the discharge pipe, there is a hot air pump, and the hot air pump is connected to the side hole of the discharge pipe through a high-temperature resistant hose.

[0013] As an improvement, the blowing device, the auxiliary blowing device, the hot air pump and the telescopic device are all connected to the conveying frame through bolt structures.

[0014] As an improvement, the inner walls of the blanking branch pipe and the stretchable plastic pipe are both provided with spiral lines.

[0015] As an improvement, the blowing device, the auxiliary blowing device, the hot air pump and the telescopic device are all connected to the power supply through wires.

[0016] The advantages of the present utility model compared with the prior art are as follows: The height of the fixed branch pipe can be changed by the height adjustment device of the present device, so as to indirectly adjust the height of the outlet of the discharge pipe, enabling it to match tea withering machines of different heights. Moreover, a bendable pipe structure is installed between the blanking branch pipe and the fixed branch pipe. The composite joint structure of the bendable pipe structure can be like the structure of a shrimp shell, which can ensure that the stretchable plastic pipe inside the composite joint structure is not damaged by external forces while not affecting the movement angle.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following further describes the present utility model in detail with reference to the accompanying drawings.

[0023] As shown in the Figure 1 and 2 drawings, it includes a conveying frame 1. Above the conveying frame 1, there are successively sleeved an air blowing device 2, a blanking branch pipe 3, a fixed branch pipe 4, and a discharge pipe 5. After sleeving the air blowing device 2, the blanking branch pipe 3, the fixed branch pipe 4, and the discharge pipe 5 in sequence, items such as sealing rubber strips are used to seal the interfaces, and the blower is fixed to the conveying frame 1 with screws.

[0024] The inner wall of the blanking branch pipe 3 is provided with a spiral line 73, which ensures the stability of the rotation of tea leaves in the pipe, and its function is the same as that of the rifling in a gun barrel.

[0025] The discharge port angle of the discharge branch pipe 3 is perpendicular to the discharge port of the main pipeline of the discharge branch pipe 3, so that when the tea leaves enter the main pipeline of the discharge branch pipe 3, the sliding direction is the same as the blowing direction of the blowing device 2, thereby preventing the tea leaves from blocking the blowing device 2 under the action of gravity.

[0026] As the instruction manual Figure 1 , 3 As shown in Figure 4, a height adjusting device 6 is provided below the fixed branch pipe 4, and the height adjusting device 6 includes a telescopic device 61 located above the conveying frame 1 and a fixed plate 62 located below the fixed branch pipe 4, and a plurality of detachable fixing clamps 63 sleeved on the outer wall of the fixed branch pipe 4 are provided above the fixed plate 62, and the fixed plate 62 is connected to the detachable fixing clamp 63 through a bolt structure, and the telescopic device 61 is connected to the conveying frame 1 through a bolt structure, and the output shaft of the height adjusting device 6 is connected to the bottom surface of the fixed plate 62 through welding, and the height of the fixed branch pipe 4 and the discharge pipe 5 can be indirectly changed by adjusting the height of the telescopic device 61, so that the discharge port of the discharge pipe 5 matches the feed port of the withering machine in height.

[0027] An auxiliary air blowing device 41 is provided on one side of the fixed branch pipe 4, and the auxiliary air blowing device 41 is connected to the conveying frame 1 through a bolt structure. A blast partition 42 is provided inside the fixed branch pipe 4, and a plurality of unidirectional inclined air blowing ports 43 are provided on the inner wall of the fixed branch pipe 4. The auxiliary air blowing device 41 is connected to the air inlet of the blast partition 42 through an air blowing hose 44. The wind force of the auxiliary air blowing device 41 blows the tea leaves entering the fixed branch pipe 4 to continue to move toward the discharge pipe 5. Because the angle of the air blowing port 43 is unidirectionally inclined, the unidirectionality of the wind direction is ensured to avoid backflow of the tea leaves. Because the material of the air blowing hose 44 connected to the auxiliary air blowing device 41 is a hose, it can automatically change the bending angle with the height of the fixed branch pipe 4.

[0028] A hot air pump 51 is provided on one side of the discharge pipe 5, and the hot air pump 51 is connected to the conveying frame 1 through a bolt structure. The hot air pump 51 is connected to the side hole of the discharge pipe 5 through a high-temperature resistant hose 52. The hot air provided by the hot air pump 51 can preheat the tea raw materials before entering the withering machine.

[0029] The flexible pipe structure 7 includes a stretchable plastic tube 71 which is sleeved on the feed port of the fixed branch pipe 4 and the discharge port of the discharge branch pipe 3, and a composite joint structure 72 located on the outer wall of the stretchable plastic tube 71. The inner wall of the stretchable plastic tube 71 is provided with a spiral line 73. The composite joint structure 72 is connected to the stretchable plastic tube 71 by a sealant (the composite joint structure 72 is similar to the structure of a shrimp shell and is commonly used at the joints of a space suit). The composite joint structure 72 protects the stretchable plastic tube 71 to prevent the stretchable plastic tube 71 from being squeezed or pierced by external force.

[0030] When the utility model is specifically implemented, the air blowing device 2, the auxiliary air blowing device 41, the hot air pump 51 and the telescopic device 61 are connected to a power source through wires. The conveying rack 1 is pushed to the feeding port of the de-enzyming machine. The height of the discharge pipe 5 is changed by adjusting the telescopic device 61 so that it is inserted into the feeding port of the de-enzyming machine, and the height of the telescopic device 61 is fixed.

[0031] The hot air pump 51 is started to preheat the discharge pipe 5. After reaching the temperature, the air blowing device 2 and the auxiliary air blowing device 41 are started. The tea raw materials are put into the main pipe of the blanking branch pipe 3 from the blanking port of the blanking branch pipe 3. Under the blowing of the air blowing device 2, after the tea is blown into the fixed branch pipe 4, under the blowing of the wind force at the air blowing port 43, the tea continues to fly towards the discharge pipe 5. After flying into the discharge pipe 5, the tea is heated by the hot air blown out by the hot air pump 51, and then flies into the feeding port of the de-enzyming machine for the de-enzyming operation.

[0032] The above describes the utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the utility model, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and without departing from the creative purpose of the utility model, without creative design, structures and embodiments similar to the technical solution are designed, they shall fall within the protection scope of the utility model.
