Description

Technical Field

[0001] This utility model relates to the field of screening device technology, and in particular to a rapid screening device for tea processing. Background Technology

[0002] The screening device is used to screen tea leaves during tea processing. It consists of a base, screening box, screening screen, feed box, spring assembly, damping rod, motor assembly, discharge plate assembly, and eccentric block. When using the screening device, the worker feeds the tea leaves from the feed box onto the screening screen inside the screening box. The first motor is started, and it is connected to the eccentric block via a reducer and coupling, causing the eccentric block to vibrate. This, in turn, causes the first spring and damping rod to continuously shake on the base. Because the screening box is tilted, the tea leaves move downwards under the vibration, causing smaller tea leaves to fall from the screening screen to the bottom of the screening box. Normal tea leaves on the screening screen are discharged from the first discharge plate, while smaller tea leaves at the bottom of the screening box are discharged from the second discharge plate, thus achieving rapid tea leaf screening.

[0003] The inventor discovered in his daily work that when the sieving device was in use, the workers would directly pour the tea leaves into the sieving screen, causing the tea leaves to pile up on the screen. In order to prevent the piled-up tea leaves from being difficult to sieve, the workers would also spread the piled-up tea leaves out by hand after pouring in the tea leaves, which could increase the labor intensity of the workers. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in actual use, when workers directly pour tea leaves into the sieving mesh, the tea leaves pile up on the mesh. To prevent the piled-up tea leaves from being difficult to sieve, workers have to spread the piled-up tea leaves out by hand after pouring them in, which may increase the labor intensity of workers. Therefore, this invention proposes a rapid sieving device for tea processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rapid sieving device for tea processing, comprising a base, a first spring and a damping rod fixedly connected to the upper end of the base, a sieving box fixedly connected to the other end of the first spring and the damping rod, a sieving screen fixedly connected to the inner wall of the sieving box, a first discharge plate and a second discharge plate fixedly connected to the left end of the sieving box, a feed box fixedly connected to the upper end of the sieving box, a first motor installed at the lower end of the sieving box, the first motor controlling the rotation of an eccentric block, a spreading assembly provided on the inner wall of the sieving box, the spreading assembly including a mounting frame inserted at the upper end of the sieving box, the mounting frame being higher than the sieving screen, two identical mounting holes being opened on the front side of the sieving screen, a mounting roller rotatably connected to the inner wall of the mounting hole by means of a bearing, a mounting groove being opened on the arc surface of the mounting roller, a belt mounted by means of the mounting groove being provided between the two mounting rollers, and a spreading plate fixedly connected to the arc surface of the belt.

[0006] The effect achieved by the above components is as follows: by setting up the spreading component, when spreading out a pile of tea leaves, the tea leaves can slide out from the space between the mounting frame and the sieve. Through the drive mechanism, the belts in the two mounting holes on the mounting frame rotate in different directions, which drives the spreading plate to rotate, so that the spreading plate comes into contact with the tea leaves and spreads them to both sides. This achieves the effect of minimizing the need for manual spreading of tea leaves and reducing the labor intensity of workers.

[0007] Preferably, a second motor is installed at the upper end of the mounting frame, and the second motor controls the rotation of the mounting roller.

[0008] The effect achieved by the above components is as follows: the second motor is started, and the second motor is connected to the mounting roller through the reducer and coupling, thereby causing the mounting roller to rotate, which in turn causes the belt on the upper side to rotate.

[0009] Preferably, a gear is fixedly connected to the lower end of the mounting roller, and a toothed ring is meshed with the arc surface of the gear, the toothed ring being fixed to the lower mounting roller.

[0010] The effect achieved by the above components is as follows: the rotation of the upper mounting roller causes the gear to rotate, which in turn causes the lower mounting roller connected to the gear ring to rotate, thereby driving the lower belt to rotate, and thus causing the belts in the two mounting holes on the mounting frame to rotate in different directions.

[0011] Preferably, the gear ring and gear pass through the mounting frame, and a rubber sleeve is fixedly connected to the surface of the spreading plate.

[0012] The effect achieved by the above-mentioned components is to prevent the tea leaves from being damaged when the board is spread out by setting up the rubber sleeve.

[0013] Preferably, a fixing component is provided between the mounting frame and the screening box, the fixing component being used to fix the mounting frame to the screening box.

[0014] The effect achieved by the above components is to fix the mounting frame to the screening box by setting the fixing components.

[0015] Preferably, the fixing component includes pins that are slidably inserted at both ends of the mounting frame, one end of the pin having a sliding surface, and the pin being inserted into the screening box.

[0016] The effect achieved by the above components is as follows: the mounting bracket is inserted into the screening box, so that the pin contacts the screening box with the help of the sliding surface, so that the pin is pushed into the mounting bracket, the reset mechanism is compressed, and after the mounting bracket is fully inserted into the screening box, the reset mechanism resets, so that the pin is inserted into the screening box, thereby fixing the mounting bracket to the screening box.

[0017] Preferably, a second spring is fixedly connected to the right end of the pin, and the other end of the second spring is fixed to the mounting bracket.

[0018] The effect achieved by the above components is that the pin is pushed into the mounting bracket and the second spring is compressed.

[0019] Preferably, a pull rope is fixedly connected to the right end of the pin, and the pull rope passes through the mounting frame.

[0020] The effect achieved by the above components is that pulling the pull rope causes the pin to retract into the mounting bracket, thereby dragging the mounting bracket for disassembly.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] In this invention, by setting up a spreading component, when spreading a pile of tea leaves, the tea leaves can slide out from the space between the mounting frame and the sieve. Through the driving mechanism, the belts in the two mounting holes on the mounting frame rotate in different directions, causing the spreading plate to rotate, so that the spreading plate comes into contact with the tea leaves and spreads them to both sides. This achieves the goal of minimizing the need for manual spreading of tea leaves, reducing the labor intensity of workers. It also solves the problem that when workers directly pour tea leaves into the sieve, the tea leaves are piled up on the sieve. In order to prevent the piled-up tea leaves from being difficult to sieve, workers will still spread the piled-up tea leaves by hand after pouring in the tea leaves, which may increase the labor intensity of workers.

[0030] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a rapid screening device for tea processing includes a base 1, a first spring 5 and a damping rod 4 are fixedly connected to the upper end of the base 1, a screening box 6 is fixedly connected to the other end of the first spring 5 and the damping rod 4, a screening screen 7 is fixedly connected to the inner wall of the screening box 6, a first discharge plate 9 and a second discharge plate 10 are fixedly connected to the left end of the screening box 6, a feed box 8 is fixedly connected to the upper end of the screening box 6, a first motor 11 is installed at the lower end of the screening box 6, the first motor 11 controls the rotation of the eccentric block, and a spreading component 2 is provided on the inner wall of the screening box 6.

[0031] Reference Figure 3 and Figure 4 as well as Figure 5As shown in this embodiment: the spreading component 2 includes a mounting frame 21 inserted at the upper end of the screening box 6. The mounting frame 21 is higher than the screening screen 7. The front of the screening screen 7 has two identical mounting holes 22. The inner wall of the mounting holes 22 is provided with mounting rollers 23 that are rotatably connected by bearings. The arc surface of the mounting rollers 23 has mounting grooves 24. A belt 25 is installed between the two mounting rollers 23 through the mounting grooves 24. The arc surface of the belt 25 is fixedly connected to the spreading plate 26. By setting up the spreading component 2, when spreading a pile of tea leaves, the tea leaves can slide out from the space between the mounting frame 21 and the screening screen 7. Through the driving mechanism, the belts 25 in the two mounting holes 22 on the mounting frame 21 rotate in different directions, thereby driving the spreading plate 26 to rotate. Thus, the spreading plate 26 contacts the tea leaves and spreads them to both sides, thereby minimizing the need for manual spreading of tea leaves and reducing costs. Due to the increased labor intensity of the workers, a second motor 27 is installed at the upper end of the mounting frame 21. The second motor 27 controls the rotation of the mounting roller 23. When the second motor 27 is started, it is connected to the mounting roller 23 through a reducer and a coupling, causing the mounting roller 23 to rotate, which in turn causes the upper belt 25 to rotate. A gear 28 is fixedly connected to the lower end of the mounting roller 23. The arc surface of the gear 28 meshes with a gear ring 29, which is fixed to the lower mounting roller 23. When the upper mounting roller 23 rotates, the gear 28 rotates, causing the lower mounting roller 23 connected to the gear ring 29 to rotate, which in turn drives the lower belt 25 to rotate. This causes the belt 25 in the two mounting holes 22 on the mounting frame 21 to rotate in different directions. The gear ring 29 and the gear 28 pass through the mounting frame 21. A rubber sleeve is fixedly connected to the surface of the spreading board 26 to prevent the spreading board 26 from damaging the tea leaves.

[0032] Reference Figure 4 As shown in this embodiment: a fixing component 3 is provided between the mounting frame 21 and the screening box 6. The fixing component 3 is used to fix the mounting frame 21 to the screening box 6. By setting the fixing component 3, the mounting frame 21 is fixed to the screening box 6. The fixing component 3 includes pins 31 that are slidably inserted at both ends of the mounting frame 21. One end of the pin 31 has a sliding surface 32. When the pin 31 is inserted into the screening box 6, the mounting frame 21 is dragged and inserted into the screening box 6, so that the pin 31 contacts the screening box 6 with the help of the sliding surface 32, so that the pin 31 is pushed into the mounting frame 21, and the reset mechanism is... After the mounting bracket 21 is fully inserted into the screening box 6, the reset mechanism resets, causing the pin 31 to be inserted into the screening box 6, thereby fixing the mounting bracket 21 to the screening box 6. The right end of the pin 31 is fixedly connected to a second spring 33, and the other end of the second spring 33 is fixed to the mounting bracket 21. The pin 31 is pushed into the mounting bracket 21, and the second spring 33 is compressed. The right end of the pin 31 is fixedly connected to a pull rope 34, which passes through the mounting bracket 21. Pulling the pull rope 34 causes the pin 31 to retract into the mounting bracket 21, thereby dragging the mounting bracket 21 for disassembly.

[0033] Working principle:

[0034] When using the screening device, the worker feeds tea leaves from the feed box 8 onto the screening screen 7 inside the screening box 6, and starts the first motor 11 (all motors used in this application are model Huilongfa 1.5KW). The first motor 11 is connected to the eccentric block through a reducer and coupling, causing the eccentric block to vibrate. This, in turn, works with the first spring 5 and damping rod 4 to continuously shake on the base 1. Because the screening box 6 is tilted, the tea leaves move downwards under the shaking, causing small tea leaves to fall from the screening screen 7 to the bottom of the inner wall of the screening box 6. After screening, the tea leaves on the screening screen 7 are... Regular tea leaves are discharged from the first discharge plate 9, while smaller tea leaves at the bottom of the inner wall of the screening box 6 are discharged from the second discharge plate 10, thus achieving rapid tea leaf screening. When the tea leaves are spread out, they can slide away from the space between the mounting frame 21 and the screening screen 7. The second motor 27 is started. The second motor 27 is connected to the mounting roller 23 through a reducer and coupling, causing the mounting roller 23 to rotate. This causes the upper belt 25 to rotate, and the upper mounting roller 23 to rotate, causing the gear 28 to rotate, which in turn causes the lower mounting roller connected to the gear ring 29 to rotate. Rotation 23 causes the lower belt 25 to rotate, which in turn causes the belts 25 in the two mounting holes 22 on the mounting frame 21 to rotate in different directions, thus causing the spreading plate 26 to rotate. This allows the spreading plate 26 to contact the tea leaves and spread them to both sides, minimizing the need for manual spreading and reducing worker workload. A rubber sleeve is used to prevent the spreading plate 26 from damaging the tea leaves. Dragging the mounting frame 21 and inserting it into the screening box 6 causes the pin 31 to contact the screening box 6 via the sliding surface 32, pushing the pin 31 back into place. When the mounting bracket 21 is inserted into the screening box 6, the second spring 33 is compressed. After the mounting bracket 21 is fully inserted into the screening box 6, the second spring 33 returns to its original position, allowing the pin 31 to be inserted into the screening box 6. (After the pin 31 is inserted into the screening box 6, fixing glue can be poured into the mounting bracket 21 to fix the pin 31 to the mounting bracket 21. When disassembling, the mounting bracket 21 is heated to melt the glue and the pin 31 is pulled out.) This fixes the mounting bracket 21 to the screening box 6. Pulling the pull rope 34 causes the pin 31 to retract into the mounting bracket 21, thereby dragging the mounting bracket 21 for disassembly.
