[0027] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The accompanying drawings provide embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0029] Combine Figure 1-4 As shown, a chain plate dryer includes:

[0030] The base 1 is the main structure of the chain plate dryer, which is rectangular and hollow inside.

[0031] The conveyor 2 is arranged inside the base 1 and is a chain plate conveyor 2, and the chain plate is set as a mesh chain plate to further increase the air permeability and enhance the drying effect;

[0032] The heating component 3 is arranged inside the base 1 and below the mesh chain plate, and quickly heats and dries the material on the surface of the mesh chain plate by spraying high-temperature air upward;

[0033] The material storage bin 4 is provided at the top of one side of the base 1 and stores the materials to be processed;

[0034] The storage box 5 is provided at the bottom of the other side of the base 1 and is used to collect the materials after drying;

[0035] A protective cover 6 is provided at the bottom of the base 1 as a protective shell;

[0036] The sieve leveling assembly 7 is arranged on the protective cover 6 and pushes the material on the surface of the conveyor 2 to move in the reverse direction by rotating, so as to avoid uneven drying due to accumulation of materials.

[0037] Specifically; in this embodiment, the upper half of the storage bin 4 is set to be rectangular, the lower half is set to be bucket-shaped, and a discharge port 41 is provided at the center of the bottom surface. Considering the width of the conveyor 2 during actual use, the discharge port 41 should be simultaneously set to a rectangular structure, and its width should be slightly smaller than the width of the mesh chain plate on the top surface of the conveyor 2, to ensure that the material can be stably discharged into the interior of the conveyor 2, while expanding the range of material discharge and increasing the contact range between the material and the hot air.

[0038] In the general discharge process, the material will naturally accumulate in the center, while the material on both sides is relatively less. Therefore, the simple discharge structure cannot effectively utilize the mesh chain plate on the top of the conveyor 2. In this embodiment, a dividing plate 42 should be installed on the inner wall of the discharge port 41 close to the feeding direction. The bottom of the dividing plate 42 extends downward and close to the top surface of the mesh chain plate, and a conical protrusion is also provided on the end surface of the dividing plate 42, such as Figure 4 As shown, in the actual use of this structure, since the material is accumulated in the center of the mesh chain plate, when feeding, the accumulated material will be guided to both sides through the inclined side walls of the protrusion, which can not only reduce the thickness of the material accumulation, but also allow the material to extend to both sides and expand the coverage of the material on the mesh chain plate, effectively improving the drying effect.

[0039] The screening assembly 7 includes a plurality of movable shafts 71 longitudinally arranged on the protective cover 6. The plurality of movable shafts 71 are arranged at intervals and are rotatably connected to the protective cover 6. A cylindrical connecting portion 72 is fixedly installed at the center of each movable shaft 71. A plurality of slots 73 are arranged around the outer wall of the connecting portion 72. A sieve plate 74 is provided inside each slot 73. When the sieve plate 74 runs to a vertical state, a certain distance is left between it and the surface of the mesh chain plate, and the distance is exactly the standard thickness of the material.

[0040] In the above structure, the structure mainly utilizes the simultaneous rotation of multiple movable shafts 71 to drive the screen plate 74 to rotate in the opposite direction, so that it pushes the material with a thickness higher than the standard in the opposite direction. When the excess material is pushed in the opposite direction, it will cause it to move to the lower part of the four sides, so that the material on the mesh chain plate can not only maintain the standard thickness, but also effectively improve the coverage area on the mesh chain plate, greatly improving the drying effect and ensuring that the material is heated evenly.

[0041] In the structure of the screen leveling assembly 7, a driving gear should be provided at both ends of each movable shaft 71, and a chain 78 should be used between two adjacent movable shafts 71 to transmit the two driving gears together, for example Figure 3 As shown, a driving motor 77 is provided on one side of the protective cover 6 through a motor base. The driving motor 77 is in transmission connection with one of the movable shafts 71 , that is, all the transmission shafts can be driven to rotate by driving one transmission shaft.

[0042] Moreover, in the above-mentioned sieve leveling assembly 7, the connecting parts 72 on the multiple movable shafts 71 should also have an adjustment structure. The purpose is to facilitate the use of this embodiment for different materials. For example, the standard thickness of relatively fluffy tea leaves and seeds can be set higher. Therefore, an adjusting ring 75 is provided at one end of the movable shaft 71. The adjusting ring 75 should be rotatably installed on the end face of the movable shaft 71, and the inward side of the adjusting ring 75 is also provided with a vortex-shaped groove, and the end face of the adjusting ring 75 is just connected with the end faces of all the slots 73, and both ends of the sieve plate 74 are provided with protrusions, one end of which is movably inserted into the groove, and the other end is movably connected to the inside of the movable shaft 71 using a groove structure. Therefore, whenever the adjusting ring 75 rotates, the entire sieve plate 74 will gather toward the center or expand outward. This structure is similar to the adjustment method of the chuck structure, which can effectively control the outward expansion length of the sieve plate 74, thereby controlling the distance between it and the surface of the mesh chain plate.

[0043] In the above structure, in order to facilitate the twisting of the adjustment ring 75, the back of the adjustment ring 75 should also extend outward to the outside of the movable shaft 71 and be provided with an adjustment handle 76. The staff can twist the adjustment ring 75 by holding the adjustment handle 76.

[0044] The heating component 3 adopts a hot air drying structure, which is composed of three parts: a blower 31, an air duct 33 and an electric heater 32. The blower 31 and the electric heater 32 are interconnected to form a hot air blower structure, that is, after the blower 31 inputs external air into the electric heater 32, the electric heater 32 uses an electric heating plate or an electric heating wire to heat the air and then inputs it into the air duct 33. In this structure, the blower 31 is fixedly connected to the inner wall of the base 1 through a metal bracket, and the air duct 33 extends as a whole along the conveying direction and is arranged with a plurality of air holes on the top surface, so that the hot air can be conveyed upward.

[0045] The air duct 33 is divided into a main pipe 331 and a branch pipe 332, wherein the main pipe 331 extends horizontally along the conveying direction, while the branch pipe 332 is arranged longitudinally, and its two ends are fixedly connected to the interior of the base 1 respectively. The main pipe 331 and the branch pipe 332 are interconnected. The multiple longitudinally arranged branch pipes 332 can not only expand the exhaust range of the hot air, but also provide stable support for the entire air duct 33 through the connection with the base 1.

[0046] The air inlet end of the blower 31 extends outward and forms an opening on the side end face of the base 1. A filter 34 should be provided at the opening to filter dust in the external air to prevent the drying material from being contaminated and to avoid clogging of the air duct 33.

[0047] In this heating structure, a solenoid valve 35 (SMC's SY7320C solenoid valve can be used) should be set at the connection between the air duct 33 and the electric heater 32. At the same time, a flow meter 36 (FSC400 ultrasonic flow meter can be used) is provided on one side of the solenoid valve 35 to monitor the hot air delivery speed in real time, thereby controlling the hot air delivery volume by controlling the solenoid valve 35.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the technical solutions of the embodiments of the present invention.
