Description

Technical Field

[0001] The present invention relates to the technical field of mechanical detection in the tea industry, and in particular to a detachable detection device for a drum tea-fixing machine. Background Art

[0002] The continuous drum-type tea-withering machine, which primarily operates by stirring, is suitable for both the fine-grained withering of premium teas and the large-scale processing of bulk teas. It is currently the most widely used tea-withering equipment. It significantly improves withering efficiency and effectively reduces labor costs. The drum of a drum-withering machine is cylindrical and typically installed inside the machine. Some users also embed the entire machine into the wall, with the opening tilted downward. The drum's discharge port is a small cylindrical design with internal fan blades.

[0003] The DG / T 079-2021 "Tea Withering Machine" standard specifies the technical parameters of a drum tea withering machine, including its inner diameter and depth. The inner diameter of the drum directly determines the height and trajectory of the tea leaves within the drum, while the depth of the drum determines the thickness of the tea leaves within the drum. A suitable drum inner diameter and depth ensure a more balanced movement of the tea leaves within the drum, allowing them to fully engage with the hot air. This not only reduces heat consumption and plays a positive role in energy conservation and environmental protection, but also better preserves the tea's color and aroma, significantly improving the withering effect.

[0004] However, due to the compact internal structure of the drum and the presence of components such as guide vanes, it is difficult to manually enter the drum to measure the inner diameter and depth during on-site inspection of the withering machine. Furthermore, this measurement method has poor repeatability, making it difficult to ensure data accuracy.

[0005] In view of this, it is urgent to study a detachable drum fixing machine detection device that is simple to operate, high in precision and easy to store. Summary of the Invention

The side of each triangle 31 is provided with a scale 32 and a fixing clamp 33. The fixing clamp 33 is passed through a moving rod 34 and a fixing knob 35 for locking the moving rod 34. The position of the moving rod 34 on the scale 32 is adjusted by the fixing clamp 33. When measuring, the three moving rods 34 are aligned with the outer edge of the opening of the roller A of the roller fixing machine, so that the regular triangular prism 2 is coaxial with the roller A.

[0037] Preferably, the end of the telescopic ruler 5 is a zero scale, and when each section of the telescopic ruler is at its maximum extension, a bayonet is provided with an adjacent telescopic ruler to prevent retraction.

[0038] Preferably, the threaded rod 62 is provided with a rotating handle 622 .

[0039] Preferably, the base 7 is further provided with two vertical guide rods 72, the bottom of the screw rod 71 is rotatably connected to the base 7, and a turntable 711 is provided on the top of the screw rod 71. The lifting platform 6 is passed through the screw rod 71 and the two vertical guide rods 72.

[0041] Preferably, the base 7 is further provided with four rollers 73 .

[0042] The working principle of the present invention is described as follows:

[0043] When in use, install the three triangles 31 on the regular triangular prism 2 in sequence, and clamp the fixing clamp 33 on the triangle 31, so that the three fixing clamps 33 are in the same position as the scale 32 of the corresponding triangle 31, pass the three moving rods 34 through the fixing clamp 33, and lock the moving rods to the fixing clamp through the fixing knob 35, adjust the extended length through the scale line on the moving rod 34, and ensure that the ends of the moving rods 34 are in contact with the opening of the roller A or maintain the same spacing (about 2-3mm), and according to the principle of geometry, make the arc formed by the three fixing clamps 33 basically coaxial with the circle of the opening of the roller A of the fixing machine and the size is basically equal. If the deviation is too large, further adjust the corresponding height and inclination by adjusting the turntable 711 of the screw 71 and the rotating handle 621 of the threaded rod 62, so as to ensure that the downward-tilted roller A of the roller fixing machine is in a coaxial position with the regular triangular prism 2.

[0044] Measurement of the inner diameter of the drum: Use the clamp 43 to fix the two-way distance meter 41 so that it is at 90° to the axis of the drum, extend the two-way distance meter 41 into the specified position in the drum A of the tea withering machine through the telescopic rod 4, use the rotating handle 42 to adjust the distance measurement direction, set the two-way distance meter 41 to measure regularly and read the data, obtain multiple sets of measurement data and record the data. Since there are fan blades on the inner wall of the drum, when adjusting the rotating handle 42, it is necessary to try to avoid the two-way distance meter sensing light beam being blocked by the fan blades. When a measurement value that is significantly smaller than the drum radius appears, it should be discarded as abnormal data because it may be caused by interference from the fan blades, and such data can be directly discarded. Finally, multiple sets of valid data that match the actual radius of the drum in different directions can be screened out to obtain the final inner diameter value and ensure measurement accuracy.

[0045] Measuring the depth of the drum: Adjust the telescopic ruler 5 to the extended state and extend it into the drum A. The zero point of the telescopic ruler 5 is at its tip. When extending the telescopic ruler 5, the tail section of the telescopic ruler should be extended first. After the tail is fully extended, the adjacent telescopic rulers should be extended in sequence until the tail of the telescopic ruler reaches the bottom of the drum A. Since each section of the telescopic ruler is equipped with a latch, when the tail of the telescopic ruler touches the bottom, each section of the telescopic ruler will not retract. Then, reach into the opening of the drum A to adjust the position of the movable clamp 52 and turn on the infrared transmitter 51. Since the drum A is cylindrical and its opening gradually shrinks, the sensing beam of the infrared transmitter needs to be aimed at the intersection of the straight section of the cylinder and the shrinking section. At this time, the depth of the drum A can be determined based on the position of the movable clamp 52 on the telescopic ruler 5.

[0046] After the inspection is complete, the movable clamp 52 can be removed from the telescopic ruler 5. The telescopic rod 4 and the telescopic ruler 5 are then retracted toward the regular triangular prism 2 and finally stored inside the regular triangular prism 2. The three movable rods 34 are then removed from the fixed clamp 33. The fixed clamp 33 is then removed from the set square 31. The three set squares 31 are then removed from the regular triangular prism 2. The bracket 1 is then removed from the tilting plate 61 using the sliding latch 613. The tilting plate's angle is restored by turning the rotary handle of the threaded rod 62. The lifting platform 6 is then lowered above the base 7 using the turntable 711 of the screw rod 71. Each component is detachable, making it easy to store and carry, making it suitable for on-site measurements of outsourced projects.

[0047] In summary, the advantages of the present invention are as follows: the present invention can improve the measurement accuracy through the positioning device, and use the two-way rangefinder to rotate to obtain multiple sets of data, eliminate abnormal data, and use the infrared emitter on the telescopic ruler to accurately locate the junction of the roller and the straight cylinder, thereby further improving the measurement accuracy. In addition, the measuring and positioning parts of the present invention can be disassembled, which is convenient for storage when not in use, and is also convenient for use outside, easy to carry, and the entire operation is simple and easy to implement.

Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included within the scope of protection of the claims of the present invention.
