Description

Technical Field

[0001] This utility model relates to the technical field of tea lifting machines, specifically a tea cooling lifting machine for white tea processing. Background Technology

[0002] Cooling is necessary during the processing of white tea because the process includes picking, withering, drying, and storage, with cooling being crucial during the drying stage. Specifically, the drying process for white tea is typically divided into two stages: initial drying and re-drying. In the initial drying stage, the temperature of the dryer is controlled at 100-120℃ for a certain period of time. Then, the temperature is controlled at 80-90℃ for a longer, lower-temperature drying. After the white tea is dried, it needs to be unloaded and cooled. This cooling process helps ensure even drying and maintains the quality of the tea leaves.

[0003] After white tea leaves are removed from the drying equipment, they not only need to be cooled but also transported to another processing step. The simplest way is to pour the tea leaves onto an elevator, where they are exposed to air for effective heat dissipation as they are conveyed forward. However, existing tea cooling elevators can only transport tea leaves upwards and cannot adjust their height. This means that the distance between the tea leaves and the inlet of different equipment cannot be adjusted when the elevator is conveying tea leaves to different devices. Therefore, we propose a tea cooling elevator for white tea processing. Utility Model Content

[0004] This invention provides a tea cooling and lifting machine for white tea processing, which has the advantage of adjustable tea conveying height and solves the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A tea cooling and lifting machine for white tea processing is designed, including a first support frame and a second support frame. The first support frame is horizontal and has walking devices on both sides. The second support frame is inclined upward and its bottom is rotatably installed in the first support frame. Both the first and second support frames are provided with conveying devices. The first support frame has a first support frame on both sides and the second support frame has a second support frame on both sides. A rotating seat is provided between the two second support frames. The rotating seat is rotatably connected to one end of an adjusting screw. A threaded seat is provided on the adjusting screw. The threaded seat is located between the two first support frames. The threaded seat and the rotating seat are both installed on a support rod. The two ends of the support rod are rotatably connected to the second support frame and the first support frame, respectively.

[0006] Preferably, a material guide funnel is provided at the top of the second support frame.

[0007] Preferably, the walking device includes support legs located at the four corners of the first support frame, and omnidirectional wheels are installed at the bottom of the support legs.

[0008] Preferably, a material trough is provided above the end of the first support frame away from the second support frame, and a material discharge port is provided at the bottom of the material trough. The two sides of the material trough are respectively connected to the first support frame through a frame.

[0009] Preferably, two baffles arranged in a "V" shape are symmetrically arranged below the material trough.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figures 1 to 5 This utility model provides a technical solution: a tea cooling and lifting machine for white tea processing, including a first support frame 1 and a second support frame 4. The first support frame 1 is horizontal and has walking devices on both sides. The walking devices include support legs 3 set at the four corners of the first support frame 1. Universal wheels are installed at the bottom of the support legs 3. The universal wheels are braked universal wheels for easy movement and positioning.

[0023] like Figure 1 and Figure 2 As shown, the second support frame 4 is tilted upwards, and its bottom is rotatably mounted inside the first support frame 1, allowing it to rotate around the first support frame 1 and thus adjust its tilt. First support frames 12 are provided on both sides of the first support frame 1, and second support frames 5 are provided on both sides of the second support frame 4. A rotating seat 9 is located between the two second support frames 5, and one end of an adjusting screw 16 is rotatably connected to the rotating seat 9. A threaded seat 10 is threaded onto the adjusting screw 16, and the threaded seat 10 is located between the two first support frames 12. Both the threaded seat 10 and the rotating seat 9 are mounted on a support rod 11, and both ends of the support rod 11 are rotatably connected to the second support frames 5 and the first support frames 12, respectively.

[0024] like Figure 4As shown, the adjusting screw 16 is perpendicular to the support rod 11, and the adjusting screw 16 is installed at the top of the first support frame 12 and the second support frame 5. This allows the adjusting screw 16 to have a certain distance from the first support frame 1 and the second support frame 4. When the adjusting screw 16 is rotated, one end of the adjusting screw 16 rotates in the rotating seat 9, while the other end of the adjusting screw 16 will extend and retract along the threaded seat 10. When the length of the adjusting screw 16 between the threaded seat 10 and the rotating seat 9 increases, the second support frame 4 rotates around the first support frame 1 and decreases in height. When the length of the adjusting screw 16 between the threaded seat 10 and the rotating seat 9 decreases, the second support frame 4 rotates around the first support frame 1 and increases in height, thereby increasing the inclination of the second support frame 4.

[0025] Because conveying devices are provided on both the surface of the first support frame 1 and the second support frame 4, the conveying device on the first support frame 1 transports the tea leaves towards the second support frame 4, allowing the tea leaves to be transported to the conveying device on the surface of the second support frame 4. The conveying device on the surface of the second support frame 4 can pull the tea leaves down from its top, causing the tea leaves to be lifted and then lowered. When the inclination of the second support frame 4 changes, the height at which the tea leaves fall can be changed.

[0026] In order to collect the falling tea leaves, a guide funnel 6 is provided at the top of the second support frame 4. The two sides of the guide funnel 6 are connected to the sides of the second support frame 4 through the frame, and the larger end of the guide funnel 6 is facing up and the smaller end is facing down, so that the tea leaves falling from the top of the second support frame 4 can be collected better.

[0027] Furthermore, in order to better place the tea leaves above the first support frame 1, a material trough 13 is provided above the end of the first support frame 1 away from the second support frame 4. The bottom of the material trough 13 is provided with a discharge port 14. The two sides of the material trough 13 are connected to the first support frame 1 through the frame. The tea leaves can be poured into the material trough 13 and fall onto the conveying device through the discharge port 14.

[0028] Meanwhile, two baffle plates 15 are symmetrically arranged in a "V" shape below the material trough 13. The baffle plates 15 are located above the middle of the conveying device, and the side of the baffle plates 15 that is far apart from each other is "L" shaped and detachably connected to the first support frame 1. Specifically, the side of the baffle plate 15 is fixed to the side of the first support frame 1 with bolts, which makes it easy to disassemble and assemble the baffle plate 15. This allows the tea leaves falling from the discharge port 14 to be concentrated between the two baffle plates 15. Since the distance between the two baffle plates 15 is located in the middle of the surface of the conveying device, the tea leaves falling from the two baffle plates 15 will fall directly into the middle of the surface of the conveying device.

[0029] The specific structure of the conveying device will be described below, such as... Figure 5As shown, the conveying device includes a conveyor belt 2 located on the surface of the first support frame 1 and the second support frame 4. Each conveyor belt 2 is provided with multiple drive shafts 18. The two ends of the drive shaft 18 are rotatably connected to the first support frame 1 and the second support frame 4 respectively. Specifically, bearing seats are rotatably installed at both ends of the drive shaft 18, and then the bearing seats are installed on the first support frame 1 and the second support frame 4.

[0030] Next, a drive device 17 connected to the transmission shaft 18 is provided on one side of the first support frame 1 and the second support frame 4. Here, the drive device 17 is a drive motor or a combination of a motor and a reducer. When the drive device 17 rotates, it can drive the conveyor belt 2 to rotate around the transmission shaft 18.

[0031] The drive shaft 18 in this application is not only used to tension the conveyor belt 2, but also, located between the two ends of the conveyor belt 2, can support the conveyor belt and prevent it from sinking and deforming. The conveyor belt 2 is a flat conveyor belt, in which case the drive shaft 18 corresponds to the conveyor belt 2, meaning the conveyor belt 2 is supported and driven by the drive shaft 18. The conveyor belt 2 can also be a conveyor chain mesh or a conveyor chain plate; in this case, both ends of the drive shaft 18 are equipped with sprockets, the type of which matches the drive chain on both sides of the conveyor chain mesh or conveyor chain plate. During installation, the drive chain on both sides of the conveyor chain mesh or conveyor chain plate is simply placed on the sprockets.

[0032] Furthermore, although the tea leaves can be cooled by walking on the conveyor belt 2, in order to accelerate the airflow around the tea leaves, a strip cover plate 8 is provided parallel above the surface of the conveyor device located on the second support frame 4. The two sides of the strip cover plate 8 are connected to the second support frame 4 through the frame. Multiple air outlets 7 are provided on the strip cover plate 8, and a fan is installed in each air outlet 7. The fan can draw air outward or blow air towards the surface of the tea leaves. When the fan rotates, it can drive the airflow around the tea leaves, which helps the tea leaves to dissipate heat better.

[0033] Based on the above embodiments, further optimization is possible by providing several spaced partitions (not shown in the figure) along the surface of the conveyor belt 2, with cavities formed between adjacent partitions, so that the tea leaves can fall into each cavity and will not scatter.

[0034] Based on the above embodiments, further optimizations can be made. In order to make it easier to rotate the adjusting screw 16, a hexagonal prism head is provided coaxially at the end of the adjusting screw 16 away from the rotating seat 9. This makes it convenient to directly rotate the adjusting screw 16 with a wrench. At least one nut is also provided on the adjusting screw 16, which can be tightened when the adjusting screw 16 is stationary.

[0035] Based on the above embodiments, it should be further explained that the second support frame 4 is rotatably installed inside the first support frame 1 at approximately two-thirds of its length, so that the first support frame 1 has protruding portions on both sides of the second support frame 4, which can effectively support the second support frame 4.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
