Description

Technical Field

[0001] The present invention relates to the technical field of positioning and fastening devices, and particularly to a positioning and fastening device for a tea green screening powder sieve and a using method thereof. Background Art

[0002] The positioning and fastening device for a tea green screening powder sieve is a device specifically designed to ensure the stable and accurate operation of the screening powder sieve during the tea green screening process in the tea processing field. The positioning and fastening device is used on the tea green screening powder sieve and realizes the precise positioning and firm fixation of the screening powder sieve through a specific structural design and working principle. This device can ensure that the screening powder sieve does not displace or shake during the screening process, thereby guaranteeing the accuracy and efficiency of screening, and is widely used in places such as tea processing enterprises and tea planting bases. Especially in processes such as tea screening and grading, this device plays a crucial role. By using the positioning and fastening device, the stability and accuracy of the screening powder sieve can be ensured, and the efficiency and quality of tea screening can be improved.

[0003] The existing defects are as follows: 1. Patent document CN118752391A discloses a positioning device for fastener production and processing, "relating to the technical field of positioning, a positioning device for fastener production and processing, including a polishing machine, an inner wall clamping and positioning mechanism is arranged on the inner wall of the polishing machine; by setting the inner wall clamping and positioning mechanism, the installation is relatively stable and cannot be directly pulled out. When it needs to be directly pulled out, just hold three push blocks with one hand and press them inward, then the three push blocks can drive the moving rod to move through the connecting plate, thereby loosening the pressed pressing plate. At this time, when the internal thread sleeve is pulled outwards again, the thread groove in the internal thread sleeve can squeeze the side of the inclined pressing plate, pushing the pressing plate, round rod, and sliding rod to deform the spring B with relatively small elasticity at this time, so that the thread groove in the internal thread sleeve will disengage from the extrusion of the pressing plate and be pulled out, completing the function of quickly positioning and disassembling the internal thread sleeve", but the existing positioning and fastening device cannot conveniently wash the tea green; 2. Patent document CN118438196A discloses a positioning device for fastener processing, "including a tapping device. At the bottom end of the output shaft of the tapping device, there is a sleeve device. At the bottom of the sleeve device, there is a guiding device. The bottom of the guiding device is fixedly connected to a buffer bottom plate. The sleeve device includes a protective cylinder shell. When the device performs tapping and drilling operations on the components clamped inside the protective cylinder shell, since the components are always located inside the protective cylinder shell, the remaining materials splashed during tapping will always be blocked by the protective cylinder shell, ensuring that the remaining materials fall above the mesh bottom plate for cleaning. When the tapping screw moves up and down, the air outlets of the bent guiding shells on both sides can blow off the remaining materials on the outer surface of the tapping rod during this process, ensuring that the tapping rod will not have serious tool wear problems due to the increase of attached waste residues during continuous operation", but the existing positioning and fastening device cannot collect and filter the sewage after flushing; 3. Patent document CN116748930A discloses a positioning device for fastener production and processing, "including a base. Above the base, there is a top plate. Between the base and the top plate, there are fixedly connected connecting curved plates. On the top of the top plate, there are respectively provided a feeding port, a discharging port and a notch. In the present invention, by utilizing the negative pressure suction effect, a pressure difference is formed on the upper and lower surfaces of the large end of the upper part of the bolt, and adsorption fixation is achieved. At the same time, in cooperation with the air supply mechanism, the gas introduced through the bottom pipe into the side clamping assembly pushes the clamping blocks distributed around the bolt to uniformly clamp the outer arc surface of the bolt. By increasing the positioning pressure in different directions, the stability is further improved while reducing the pressure of side clamping, avoiding over-clamping of the bolt under rigid extrusion, thereby further improving the clamping stability while avoiding damage to the bolt surface. The rounding at the large end of the upper part of the actual bolt is stable and reliable, and the quality of the processed bolts is high, with good use effects", but the existing positioning and fastening device cannot handle impurities.

[0013] Preferably, the usage method of this positioning and fastening device is as follows: Step S1: After the tea greens are screened, the water inlet pump supplies water from the outside to the water storage tank. Before the water enters the interior of the water storage tank, the water from the outside is transported to the filter frame through the water inlet pipe. The impurity filter screen in the filter frame filters the water from the outside and then enters the water storage tank. The impurity filter screen is removed from the sealing screw groove by rotating the sealing screw cap. The impurity filter screen can be disassembled, cleaned, or installed through the sealing screw groove. The limit block is used to limit the position of the impurity filter screen to prevent deviation. When the filtered water enters the water storage tank, the observation window can observe the water level line in the water storage tank. The floating plate moves on the sliding rod as the water level rises. Subsequently, the water inlet end of the water pump extends into the interior of the water storage tank, and the water outlet end extends into the interior of the spray plate. The water pump transports the water in the water storage tank to the spray plate. The spray plate supplies liquid to the spray heads, and the spray heads are used to wash the dust on the tea greens. Step S2. After the tea green is rinsed, the rinsing water needs to be collected and filtered for convenient discharge. The outer collecting cylinder is placed inside the installation groove. Subsequently, the linkage block is fixed to the linkage groove through the fixing rod, so that the linkage rod is fixedly connected to the bottom of the lifting plate through the large screening net for the discharge of the rinsing water. When the lifting plate adjusts its height according to the working environment, the movement of the lifting plate can drive the movement of the linkage rod, and the movement of the linkage rod drives the slider to move in the chute, so that the inner collecting cylinder ring moves inside the outer collecting cylinder, increasing the accommodation volume of the outer collecting cylinder. Subsequently, when the rinsing water enters the outer collecting cylinder, the fine filter screen filters out the impurities in the sewage, completing the treatment of the sewage. When discharging the water, the outer collecting cylinder has its own drainage end. The fixing rod is removed from the linkage groove, and then the fixing rod is fixed to the locking groove through the corresponding through groove to fix the position of the inner collecting cylinder ring, preventing the inner collecting cylinder ring from automatically sinking and causing the waste water to overflow. Subsequently, the outer collecting cylinder is removed from the installation groove for convenient discharge of the waste water; Step S3. After the waste water is filtered, the impurities on the filter screen need to be disassembled and cleaned. The blocking plate is used to lift and limit the fine filter screen, and the inclined plate is used to prevent the waste water from accumulating on the top of the detachable inner plate during the filtering process. Subsequently, the detachable inner plate is pulled, so that the hemispherical block is squeezed against the hemispherical groove, and the spring is compressed, causing the hemispherical block to move out of the hemispherical groove, thus disassembling the detachable inner plate. After the disassembly is completed, the fine filter screen is slowly pulled out from the top of the blocking plate, completing the disassembly of the fine filter screen for convenient cleaning later; Step S4. When the rinsing water enters the outer collecting cylinder, the fine filter screen filters out the impurities in the sewage, completing the treatment of the sewage. However, if the impurities accumulate on the fine filter screen for a long time, the mesh holes will be blocked, resulting in the inability to perform subsequent filtering. Therefore, the fine filter screen needs to be disassembled and cleaned. The detachable inner plate is pulled, so that the hemispherical block is squeezed against the hemispherical groove, and the spring is compressed, causing the hemispherical block to move out of the hemispherical groove, thus disassembling the detachable inner plate. After the disassembly is completed, the fine filter screen is slowly pulled out from the top of the blocking plate, completing the disassembly of the fine filter screen.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention is equipped with a flushing mechanism, which is used to flush the dust on the selected tea greens. After the tea greens are screened, the water inlet pump supplies water from the outside to the water storage tank. Before the water enters the interior of the water storage tank, the water from the outside is transported to the filter frame through the water inlet pipe, and the impurity filter screen in the filter frame filters the water from the outside and then enters the water storage tank. Moreover, the impurity filter screen is removed from the sealing screw groove by rotating the sealing screw cap, and the impurity filter screen can be disassembled, cleaned or installed through the sealing screw groove. The limiting block is used to limit the position of the impurity filter screen to prevent deviation. When the filtered water source enters the water storage tank, the observation window can observe the water level line in the water storage tank. The floating plate moves on the sliding rod as the water level rises. Subsequently, the water inlet end of the water pump extends into the interior of the water storage tank, and the water outlet end extends into the interior of the spray plate. The water pump transports the water in the water storage tank to the spray plate, and the spray plate supplies liquid to the spray heads, and the spray heads are used to flush the dust on the tea greens; 2. The present invention is equipped with a waste water filtering mechanism, which is used to filter and process the water after being flushed by the flushing mechanism. After the tea greens are flushed, it is necessary to collect and filter the flushed water for convenient discharge. The collection outer cylinder is placed into the installation groove, and then the linkage block is fixed to the linkage groove through the fixing rod, so that the linkage rod is fixedly connected to the water discharged through the large screening net to the bottom of the lifting plate. When the lifting plate adjusts its height according to the working environment, the movement of the lifting plate can drive the movement of the linkage rod, and the movement of the linkage rod drives the slider to move in the sliding groove, so that the collection inner barrel ring moves inside the collection outer cylinder, increasing the accommodation volume of the collection outer cylinder. Subsequently, when the flushed water enters the collection outer cylinder, the fine filter screen filters the impurities in the sewage, completing the treatment of the sewage. When discharging the water, the collection outer cylinder is self-equipped with a drainage end. The fixing rod is removed from the linkage groove, and then the fixing rod is fixed to the locking groove through the corresponding through groove to fix the position of the collection inner barrel ring, preventing the situation that the collection inner barrel ring automatically sinks and causes the waste water to overflow. Subsequently, the collection outer cylinder is removed from the installation groove to facilitate the discharge of the waste water; 3. The present invention is equipped with a disassembly and cleaning mechanism. The disassembly mechanism is used to disassemble the fine filter screen. After the waste water is filtered, the impurities on the filter screen need to be disassembled and cleaned. The blocking plate is used to lift and limit the fine filter screen, and the inclined plate is used to prevent the waste water from accumulating on the top of the detachable inner plate during the filtering process. Subsequently, the detachable inner plate is pulled, so that the hemispherical block is squeezed against the hemispherical groove, and the spring is compressed so that the hemispherical block is removed from the hemispherical groove, then the detachable inner plate is disassembled. After the disassembly is completed, the fine filter screen is slowly pulled out from the top of the blocking plate, completing the disassembly of the fine filter screen, which is convenient for later cleaning; 4. In the present invention, with a fine filter screen, hemispherical blocks and springs installed, when the rinsed water enters the collection outer cylinder, the fine filter screen filters out impurities in the sewage. Pulling the detachable inner plate causes the hemispherical blocks to be squeezed against the hemispherical grooves, so that the springs are compressed and the hemispherical blocks are moved out of the hemispherical grooves, then the detachable inner plate can be disassembled. After the disassembly is completed, slowly pull the fine filter screen out from the top of the blocking plate, and the disassembly of the fine filter screen is completed.

After the disassembly is completed, the fine filter screen 30 is slowly pulled out from the top of the baffle plate 38, completing the disassembly of the fine filter screen 30, which is convenient for later cleaning; Example 4: Please refer to Figure 1 , Figure 6 , Figure 7 and Figure 8 , an embodiment provided by the present invention: A fine filter screen 30 is provided on the inner wall of the collection inner barrel ring 29. The baffle plate 38 is located on the inner wall of the collection inner barrel ring 29, and the detachable inner plate 39 is located on the inner wall of the collection inner barrel ring 29 and is above the fine filter screen 30. A clamping groove 40 is provided on the outer wall of the detachable inner plate 39. A rod body 41 is installed on the inner wall of the clamping groove 40. A pushing block 42 is installed around the outer wall of the rod body 41. A spring 43 is installed on the inner wall of the clamping groove 40, and one end of the spring 43 extends to the outer wall of the pushing block 42. A hemispherical block 44 is installed on the outer wall of the pushing block 42. A hemispherical groove 45 is provided on the inner wall of the collection inner barrel ring 29. When the rinsed water enters the collection outer cylinder 26, it passes through the fine filter screen 30 to filter the impurities in the sewage, completing the sewage treatment. If the impurities on the fine filter screen 30 accumulate for a long time, they will block the mesh holes and prevent subsequent filtering. Therefore, the fine filter screen 30 needs to be disassembled and cleaned. Then the detachable inner plate 39 is pulled, causing the hemispherical block 44 to be squeezed against the hemispherical groove 45. Then the spring 43 is compressed, causing the hemispherical block 44 to move out of the hemispherical groove 45, and the detachable inner plate 39 is disassembled. After the disassembly is completed, the fine filter screen 30 is slowly pulled out from the top of the baffle plate 38, completing the disassembly of the fine filter screen 30.

[0022] The usage method of this positioning and fastening device is as follows: Step S1. After the tea green screening is completed, the water inlet pump 10 supplies water from the external water source to the water storage tank 9. Before the water enters the interior of the water storage tank 9, the external water source transports the water through the water inlet pipe 11 to the filter frame 19. The impurity filter screen 22 in the filter frame 19 filters the external water source and then the water enters the water storage tank 9. The impurity filter screen 22 is removed from the sealing screw groove 20 by rotating the sealing screw cap 21. The impurity filter screen 22 can be disassembled, cleaned or installed through the sealing screw groove 20. The limit block 23 is used to limit the position of the impurity filter screen 22 to prevent deviation. When the filtered water source enters the water storage tank 9, the observation window 17 can observe the water level line in the water storage tank 9. The floating plate 16 moves on the sliding rod 48 as the water level rises. Subsequently, the water inlet end of the water pump 15 extends into the interior of the water storage tank 9, and the water outlet end extends into the interior of the spray plate 13. The water pump 15 transports the water in the water storage tank 9 to the spray plate 13, and the spray plate 13 supplies liquid to the spray heads 14. The spray heads 14 are used to wash the dust on the tea green. Step S2. After the tea green is washed, it is necessary to collect and filter the washed water for convenient discharge. The collection outer cylinder 26 is placed into the installation groove 25. Subsequently, the linkage block 32 is fixed to the linkage groove 33 through the fixing rod 34, so that the linkage rod 31 is fixedly connected to the washed water discharged to the bottom of the lifting plate 4 through the large screening net 8. When the lifting plate 4 adjusts the height according to the working environment, the movement of the lifting plate 4 can drive the movement of the linkage rod 31. The movement of the linkage rod 31 drives the slider 28 to move in the chute 27, so that the collection inner barrel ring 29 moves inside the collection outer cylinder 26, increasing the accommodation volume of the collection outer cylinder 26. Subsequently, when the washed water enters the collection outer cylinder 26, the fine filter screen 30 filters the impurities in the sewage, completing the treatment of the sewage. When discharging the water, the collection outer cylinder 26 has its own drainage end. The fixing rod 34 is removed from the linkage groove 33, and then the fixing rod 34 is fixed to the locking groove 37 through the corresponding through groove 36 to fix the position of the collection inner barrel ring 29, preventing the situation that the collection inner barrel ring 29 automatically sinks and causes the waste water to overflow. Subsequently, the collection outer cylinder 26 is removed from the installation groove 25 to facilitate the discharge of the waste water. Step S3. After filtering the waste water, the impurities on the filter screen need to be disassembled and cleaned. The blocking plate 38 is used to lift and limit the fine filter screen 30. The inclined plate 47 is used to prevent the waste water from accumulating on the top of the detachable inner plate 39 during the filtering process. Subsequently, the detachable inner plate 39 is pulled, so that the hemispherical block 44 is squeezed against the hemispherical groove 45, and the spring 43 is compressed so that the hemispherical block 44 is removed from the hemispherical groove 45, then the detachable inner plate 39 is disassembled. After the disassembly is completed, the fine filter screen 30 is slowly pulled out from the top of the blocking plate 38, then the disassembly of the fine filter screen 30 is completed, facilitating its cleaning in the later stage.

[0023] Working principle: After the tea greens are screened, the water inlet pump 10 supplies water from the external water source to the water storage tank 9. Before the water enters the interior of the water storage tank 9, the external water source transports water through the water inlet pipe 11 to the filter frame 19, and the impurity filter net 22 in the filter frame 19 filters the external water source before entering the water storage tank 9. The impurity filter net 22 is removed from the sealing screw groove 20 by rotating the sealing screw cap 21, and the impurity filter net 22 can be disassembled, cleaned or installed through the sealing screw groove 20. The limit block 23 is used to limit the position of the impurity filter net 22 to prevent deviation. When the filtered water source enters the water storage tank 9, the observation window 17 can observe the water level line in the water storage tank 9. The floating plate 16 moves on the sliding rod 48 as the water level rises. Subsequently, the water inlet end of the water pump 15 extends into the interior of the water storage tank 9, and the water outlet end extends into the interior of the spray plate 13. The water pump 15 transports the water in the water storage tank 9 to the spray plate 13, and the spray plate 13 supplies liquid to the spray heads 14, and the spray heads 14 are used to wash the dust on the tea greens. After the tea greens are washed, the washed water needs to be collected and filtered for convenient discharge. The collection outer cylinder 26 is placed into the installation groove 25. Subsequently, the linkage block 32 is fixed to the linkage groove 33 through the fixing rod 34, so that the linkage rod 31 is fixedly connected to the washed water discharged to the bottom of the lifting plate 4 through the large screening net 8. When the lifting plate 4 adjusts its height according to the working environment, the movement of the lifting plate 4 can drive the movement of the linkage rod 31, and the movement of the linkage rod 31 drives the slider 28 to move in the sliding groove 27, so that the collection inner barrel ring 29 moves inside the collection outer cylinder 26, increasing the accommodation volume of the collection outer cylinder 26. Subsequently, when the washed water enters the collection outer cylinder 26, the fine filter net 30 filters the impurities in the sewage, completing the treatment of the sewage. When discharging the water, the collection outer cylinder 26 has its own drainage end. The fixing rod 34 is removed from the linkage groove 33, and then the fixing rod 34 is fixed to the locking groove 37 through the corresponding through groove 36 to fix the position of the collection inner barrel ring 29, preventing the situation that the collection inner barrel ring 29 automatically sinks and causes the waste water to overflow. Subsequently, the collection outer cylinder 26 is removed from the installation groove 25 for convenient discharge of the waste water. After the waste water is filtered, the impurities on the filter net need to be disassembled and cleaned. The blocking plate 38 is used to lift and limit the fine filter net 30, and the inclined plate 47 is used to prevent the waste water from accumulating on the top of the detachable inner plate 39 during the filtering process. Subsequently, the detachable inner plate 39 is pulled, so that the hemispherical block 44 is squeezed against the hemispherical groove 45, and the spring 43 is compressed, causing the hemispherical block 44 to move out of the hemispherical groove 45, then the detachable inner plate 39 is disassembled. After the disassembly is completed, the fine filter net 30 is slowly pulled out from the top of the blocking plate 38, completing the disassembly of the fine filter net 30, which is convenient for cleaning it later.

The method for using the positioning and fastening device for a green tea powder screening sieve according to any one of claims 1 to 8, characterized in that: The working steps of the positioning and fastening device are as follows: S1. After the screening of green tea leaves is completed, the water inlet pump (10) supplies water from an external water source to the water storage tank (9). Before the water enters the water storage tank (9), the external water source is transported to the filter frame (19) through the water inlet pipe (11). The external water source is filtered by the impurity filter (22) in the filter frame (19) before entering the water storage tank (9). The impurity filter (22) is removed from the sealing screw groove (20) by rotating the sealing screw cover (21). The impurity filter (22) is disassembled, cleaned or installed through the sealing screw groove (20). The limit block (23) is used to filter the impurities. The position of the filter (22) is limited to avoid deviation. When the filtered water source enters the water tank (9), the observation window (17) can observe the water level line in the water tank (9). The floating plate (16) moves on the slide bar (48) as the water level rises. Then, the water inlet end of the water pump (15) extends to the inside of the water tank (9), and the water outlet end extends to the inside of the spray plate (13). The water pump (15) transports the water in the water tank (9) to the spray plate (13). The spray plate (13) supplies liquid to the spray head (14), and the dust on the green tea leaves is washed away by the spray head (14). S2. After the green tea leaves are rinsed, the rinsed water needs to be collected and filtered for easy discharge. The collecting outer cylinder (26) is placed inside the mounting groove (25), and then the linkage block (32) is fixed to the linkage groove (33) through the fixing rod (34), so that the linkage rod (31) and the rinsed water are discharged to the bottom of the lifting plate (4) through the large screening net (8). When the lifting plate (4) is adjusted in height according to the working environment, the lifting plate (4) moves to drive the linkage rod (31) to move, and the linkage rod (31) moves to drive the slider (28) to move in the slide groove (27), so that the collecting inner barrel ring (29) is inside the collecting outer cylinder (26). The outer part of the collecting cylinder (26) is moved to increase the storage volume of the collecting cylinder (26). Then, when the flushed water enters the collecting cylinder (26), it passes through the fine filter screen (30) to filter the impurities in the sewage, thereby completing the sewage treatment. When the water is discharged, the collecting cylinder (26) is provided with a drainage end. The fixing rod (34) is removed from the linkage groove (33). Then, the fixing rod (34) is fixed to the locking groove (37) through the corresponding through groove (36). The position of the collecting inner barrel ring (29) is fixed to prevent the collecting inner barrel ring (29) from automatically sinking and causing the sewage to overflow. Then, the collecting cylinder (26) is removed from the mounting groove (25) to facilitate the discharge of the sewage. S3. After filtering the wastewater, impurities on the filter screen need to be removed and cleaned. The blocking plate (38) is used to lift and limit the fine filter screen (30). The inclined plate (47) is used to prevent wastewater from accumulating on the top of the removable inner plate (39) during the filtering process. The removable inner plate (39) is then pulled to squeeze the hemispherical block (44) and the hemispherical groove (45). The spring (43) is compressed to move the hemispherical block (44) out of the hemispherical groove (45). The removable inner plate (39) is then removed. After the removal is completed, the fine filter screen (30) is slowly pulled out from the top of the blocking plate (38). The removal of the fine filter screen (30) is completed, which is convenient for cleaning it later. S4, when the flushed water enters the collecting outer cylinder (26), it passes through the fine filter (30) to filter impurities in the sewage, and the sewage treatment is completed. However, if the impurities on the fine filter (30) are accumulated for a long time, the mesh will be blocked and subsequent filtering will be impossible. Therefore, the fine filter (30) needs to be disassembled and cleaned. The removable inner plate (39) is pulled so that the hemispherical block (44) and the hemispherical groove (45) are squeezed. The spring (43) is compressed so that the hemispherical block (44) is moved out of the hemispherical groove (45). Then, the removable inner plate (39) is disassembled. After the disassembly is completed, the fine filter (30) is slowly pulled out from the top of the blocking plate (38), and the disassembly of the fine filter (30) is completed.
