DETAILED DESCRIPTION
[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of the present application.
[0025] Please refer to Figures 1 to 5 The present application provides a technical scheme: a drying equipment with automatic feeding function, comprising an oven 1, a first conveying assembly 2 is rotatably connected to the inner wall of one end of the oven 1, a storage box 3 is fixedly connected to the upper side of one end of the first conveying assembly 2, a rotating plate 4 is rotatably connected to the upper side of the other end of the first conveying assembly 2, a second conveying assembly 5 is rotatably connected between the inner walls of the oven 1, a cleaning assembly 6 is rotatably connected below the second conveying assembly 5 on the inner walls of the oven 1, a heating rod 7 is fixedly connected to the inner top wall of the oven 1, a fan 8 is fixedly connected above the heating rod 7, a third conveying assembly 9 is rotatably connected to one side of the second conveying assembly 5, and a synchronous part 10 is rotatably connected to the outer wall of the oven 1 at positions corresponding to the second conveying assembly 5 and the cleaning assembly 6.
[0026] The second conveying assembly 5 is composed of a chain wheel 501, a chain 502 and a chain plate 503, the chain wheels 501 are coaxial and adjacent in twos in the transverse direction, the chain 502 is engaged between two chain wheels 501 that are not coaxial and connected in different groups, and the chain plates 503 are rotatably connected between the chains 502 through pins.
[0027] The cleaning assembly 6 comprises a steering rod 601, a rolling brush 602, a first bevel gear 603 and a second bevel gear 604, the first bevel gear 603 and the second bevel gear 604 are rotatably connected to one side of the inner wall of the oven 1, the first bevel gear 603 and the second bevel gear 604 are vertically distributed and connected in meshing, one end of the shaft rod of the first bevel gear 603 is fixedly connected to the bottom of the steering rod 601, and the rolling brush 602 is sleeved on the outer wall of the steering rod 601.
[0028] The synchronous part 10 is composed of two synchronous wheels and a toothed belt engaged on the outer wall of the synchronous wheels, and the cleaning assemblies 6 are connected through another two synchronous parts 10.
[0029] In the present embodiment, as Figure 1As shown, the oven 1 has heat dissipation vents on both sides of its outer wall, and a viewing window with tempered glass is opened on the outer wall of the oven 1 opposite to the storage box 3. Half of the third conveying component 9 is rotatably connected to the inside of the oven 1, and the other half is rotatably connected to the outside of the oven 1. At the same time, the oven 1 has a discharge port above the corresponding third conveying component 9. The third conveying component 9 consists of two sets of rollers and a conveyor belt covering the outside of the rollers. The heat dissipation vents on both sides of the outer wall of the oven 1 can effectively dissipate the heat generated inside the oven 1 by the operation of the heating rod 7. This helps to maintain the stability of the temperature inside the oven 1 and ensures that the drying process is carried out in a suitable temperature environment, thereby improving the stability of the tea drying quality. The viewing window allows the operator to directly observe the drying status of the tea inside the oven 1, such as the change in tea color and the conveying speed, to ensure that the tea achieves the ideal drying effect and improve the controllability of product quality. The fact that half of the third conveying component 9 is inside the oven 1 and half is outside achieves seamless connection between the drying and discharge processes, reduces the residence time of the material in the oven 1, and reduces the risk of over-drying.
[0030] In this embodiment, as Figure 1 As shown, the structure of the first conveying component 2 is the same as that of the second conveying component 5, and they are inclined. The bottom wall of the storage box 3 is a 45° inclined base plate, and the lowest point of the base plate is located above the lower end of the first conveying component 2. The rotating plate 4 is rotatably connected above the higher end of the first conveying component 2, and the two ends of the rotating plate 4 have a sawtooth structure. The inclined distribution of the first conveying component 2, combined with the inclined base plate of the storage box 3, and the rotation of the rotating plate 4, allows for precise control of the flow rate of material entering the next process by adjusting the rotation speed of the rotating plate 4. Operators can feed large quantities of tea raw materials into the storage box 3 without worrying about excessive tea flowing into the drying area at the same time. This avoids repeated feeding and prevents a large amount of material from flowing into the subsequent processing area at once, which would lead to poor tea drying effect. The sawtooth of the rotating plate 4 can disperse and loosen the material, which helps the material to better contact with hot air or other processing media in the subsequent drying or processing, improving the processing effect and quality.
[0031] In this embodiment, as Figure 1As shown, the second conveying components 5 are distributed at equal distances vertically. One end of the uppermost second conveying component 5 is located below the higher end of the first conveying component 2, and the other end of the lowermost second conveying component 5 is located above the third conveying component 9. Guide plates 11 are fixedly connected between adjacent second conveying components 5, and the guide plates 11 are symmetrically distributed. Each guide plate 11 consists of a vertical short plate and inclined long plates distributed at 45°, with the inclined plates of the guide plates 11 adjacent to the chain plate 503 of the corresponding second conveying component 5. The second conveying components 5, distributed at different heights, continuously alternate through transmission, ensuring that the tea leaves are evenly heated and dried at different height levels within the drying oven 1, which is beneficial for improving… The uniformity and consistency of drying ensure drying quality. The arrangement of the second conveying component 5 with the first conveying component 2 and the third conveying component 9 helps the material to be transferred in an orderly manner between different components, avoiding spillage and waste. The guide plate 11 prevents tea leaves from falling off the chain plate 503 during the transfer between the two sets of second conveying components 5 at different heights. Its inclined long plate can guide the tea leaves to be smoothly transferred from the chain plate 503 of the upper second conveying component 5 to the chain plate 503 of the lower second conveying component 5 along the inclined direction, realizing a smooth transition of tea leaves between different layers, reducing the accumulation and scattering of tea leaves during the transfer process, and improving the stability and efficiency of material transfer.
[0032] In this embodiment, as Figure 1 As shown, the chain plate 503 is distributed in a ring along the chain 502, and the surface of the chain plate 503 is provided with mesh-like through holes for ventilation. The chain plate 503 is distributed in a ring along the chain 502, which can form a stable circulating conveying structure. Its metal material can ensure that the tea leaves move forward stably and continuously during the conveying process, and its surface through holes can allow the hot air in the drying oven 1 to penetrate the material layer more fully. Taking tea drying as an example, the hot air can directly contact each tea leaf, accelerate the moisture evaporation rate, improve the drying efficiency, and make the tea drying more uniform and thorough.
[0033] In this embodiment, as Figure 1 As shown, a collection trough 12 is slidably connected below the second conveying component 5 at the bottom of the oven 1. During the drying of tea or other material processing, some debris, dust or falling material particles will be generated. The collection trough 12 can effectively catch these substances falling from the through holes of the chain plate 503, preventing them from accumulating at the bottom of the oven 1, avoiding pollution of the internal environment of the oven 1, keeping the inside of the equipment clean, and facilitating the normal operation and maintenance of the equipment.
[0034] In this embodiment, as Figure 1As shown, the steering rod 601 forms a horizontal flipping structure on the inner wall of the oven 1 via the first bevel gear 603 and the second bevel gear 604. The roller brush 602 is located between the adjacent second conveying components 5, and the roller brush 602 is closely attached to the lower part of the corresponding chain plate 503, forming a rotating structure through the driven chain plate 503. The roller brush 602 is closely attached to the lower part of the chain plate 503. When the chain plate 503 rotates, it will drive the roller brush 602 to rotate. This rotation allows the roller brush 602 to thoroughly and continuously clean the surface of the chain plate 503. It can effectively remove tea leaves, dust and other impurities remaining on the chain plate 503, ensuring the cleanliness of the chain plate 503, thereby avoiding contamination of the dried tea leaves by impurities and improving product quality. With the transmission of the first bevel gear 603 and the second bevel gear 604, the horizontal flipping structure can flip the roller brush 602 to a suitable position when cleaning is not required, so as to avoid affecting the normal operation of the conveying components; when cleaning is required, the roller brush 602 can be quickly flipped to the working position so that it fits against the chain plate 503 for cleaning.
[0035] The method of use and advantages of this utility model: The drying equipment with automatic feeding function operates as follows:
[0036] like Figure 1 , Figure 2 and Figure 3As shown, the drying oven 1 is equipped with a temperature sensor and a temperature controller, which can precisely control the working state of the heating rod 7 to ensure that the tea is dried within the set suitable temperature range. The storage box 3 is used to store the tea to be processed, and its bottom wall is designed with an inclination. After the power is turned on, the motor drives the first conveying component 2 to operate. The first conveying component 2 and the second conveying component 5 have the same structure, both consisting of sprockets 501, chains 502 and chain plates 503. A set of coaxial sprockets 501 rotates under the drive of the motor, and drives the other sprockets 502 through the chain 502. A set of sprockets 501 rotates, thereby driving the chain plate 503. The storage box 3 with its inclined bottom plate transports the tea leaves from the lowest point to the highest point of the first conveying assembly 2 under the action of gravity and the transmission of the chain plate 503. The rotating plate 4, located above the higher end of the first conveying assembly 2, has serrated ends and acts as a stripper to prevent a large amount of tea leaves from flowing into the subsequent processing area at the same time. The tea leaves falling from the highest point of the first conveying assembly 2 land on the chain plate 503 of the uppermost second conveying assembly 5. The tea leaves are driven by the chain plate 503 and guided by the guide plate 11. Guided by the bottom, the tea leaves sequentially enter the middle and lower second conveyor components 5. The fan 8 and heating rod 7 on the top wall of the drying oven 1 work together to generate hot air to dry the tea leaves. Finally, the tea leaves are discharged from the bottom second conveyor component 5 to the third conveyor component 9, realizing the discharge. After the drying process is completed, the power is turned on, the synchronizing component 10 operates, and the two synchronous pulleys at the shaft of the second bevel gear 604 in the middle cleaning component 6 rotate. Through the toothed belt, the upper and lower sets of synchronous pulleys rotate synchronously, thereby driving the second bevel gear 604 connected to it on the same shaft. 04. Synchronous rotation causes the three first bevel gears 603 to rotate horizontally, thereby causing the steering rod 601, which is fixed to the first bevel gear 603, to rotate horizontally. This causes the roller brush 602, which is sleeved on the outer wall of the steering rod 601, to unfold and adhere to the bottom of the chain plate 503. When the chain plate 503 is driven, the roller brush 602 generates relative movement with it, cleaning the surface of the chain plate 503. Since the surface of the chain plate 503 has ventilation holes, the dust generated during cleaning falls into the collection groove 12 that is slidably connected below. The dust can be collected and cleaned by removing the collection groove 12.
