[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1: As Figure 1-6 As shown, a screen assembly includes a screen frame 1 set on a tea shaking screen device, including a screen frame assembly 3, a discharge port 32, and a sieving assembly 2. Part of the screen frame assembly 3 is inserted into the screen frame 1. In use, a shaking assembly is installed on the outside of the screen frame 1 to shake the screen frame 1, the screen frame assembly 3, and the sieving assembly 2. The shaking assembly includes at least one vibration motor. When energized, the vibration motor is operated to shake the screen frame assembly 3 and the sieving assembly 2 to perform shaking and sieving.
[0024] The sieving assembly 2 is disposed within the screen frame assembly 3. The sieving assembly 2 includes a mounting plate 21 detachably connected to the screen frame assembly 3. A screen 24 is fixedly connected to one side of the mounting plate 21 on the screen frame assembly 3. The screen 24 and the mounting plate 21 are designed at a 90° angle. The mounting plate 21 is connected to the screen frame assembly 3 by bolts. The screen 24 is a sieve plate used for sieving tea leaves. A discharge plate 23 is fixedly connected to the end face of the screen 24 away from the mounting plate 21. The discharge plate 23 and the screen 24 are designed at an angle to increase the discharge speed and prevent tea leaves from accumulating on the discharge plate. At position 23, it rebounds again to the surface of the screen 24. A partition 22 is fixedly connected to the end face of the discharge plate 23 within the screen frame assembly 3. The partition 22 defines the positions of the discharge plate 23 and the screen 24. The total length and width of the screen 24 and the discharge plate 23 are consistent with the internal length and width of the screen frame assembly 3. The bottom of the partition 22 is L-shaped, and the bottom of the partition 22 abuts against the inner bottom of the screen frame assembly 3. The length of the protruding part of the partition 22 should be designed according to the width of the specific storage frame 31. The L-shaped partition 22, such as... Figure 6 As shown, its protruding part will abut against the bottom of the discharge port 32, and the part located inside the screen frame assembly 3 will abut against the bottom of the screen frame assembly 3, increasing the overall support of the screening assembly 2. At the same time, the two sides of the screen mesh 24 and the discharge plate 23 are consistent with the internal length of the screen frame assembly 3, which will further increase the support between the screening assembly 2 and the screen frame assembly 3, reduce the shaking amplitude of the screening assembly 2 after being subjected to force, and the protruding part of the top of the partition plate 22 extends to the outside of the discharge port 32, further reducing the probability of the screening assembly 2 and the screen frame assembly 3 falling off.
[0025] The overall effect of this embodiment is as follows: before use, the sieving assembly 2 and the screen frame assembly 3 are assembled. Since the limiting groove 4 and the mounting plate 21 are designed at 90°, the mounting plate 21 is connected to the screen frame assembly 3 by bolts. The screen mesh 24 is a screen plate used for sieving tea leaves. At the same time, the discharge plate 23 and the screen mesh 24 are designed with inclined surfaces to increase the discharge speed and prevent tea leaves from accumulating at the discharge plate 23 and rebounding to the surface of the screen mesh 24. The protruding part of the partition plate 22 will abut against the bottom of the discharge port 32, and the part located inside the screen frame assembly 3 will abut against the bottom of the screen frame assembly 3, increasing the overall support of the sieving assembly 2. The force, and the fact that the sides of the screen 24 and the discharge plate 23 are the same length as the inside of the screen frame assembly 3, will further increase the support force between the screen assembly 2 and the screen frame assembly 3, reduce the shaking amplitude of the screen assembly 2 after being subjected to force, and the protruding part of the top of the partition plate 22 extends to the discharge port 32, further reducing the probability of the screen assembly 2 and the screen frame assembly 3 falling off. Then, a shaking component is installed on the outside of the shaking screen frame 1 to shake the shaking screen frame 1, the screen frame assembly 3 and the screen assembly 2. The shaking component includes at least one vibration motor. The vibration motor is powered on to operate and shake the screen frame assembly 3 and the screen assembly 2 to perform shaking screening.
[0026] Example 2: Figure 1-6 As shown, a screen assembly has a limiting groove 4 provided in the shaking screen frame 1 and the screen frame assembly 3. The limiting groove 4 is used to fix the screen frame assembly 3 and the shaking screen frame 1. A connector 5 is slidably inserted into the limiting groove 4. The connector 5 is used to insert into the limiting groove 4.
[0027] The limiting groove 4 includes a first groove 41, a second groove 42, a third groove 43, and a fourth groove 44. The first groove 41 and the second groove 42 are located at both ends of the fourth groove 44, and the third groove 43 is located on the back of the first groove 41, the second groove 42, and the fourth groove 44, for the insertion piece 5 to slide. The side of the fourth groove 44 is designed in an "L" shape to limit the position of the insertion piece 5. The sides of the first groove 41 and the second groove 42 are designed in a circular shape to insert the insertion piece 5. The width of the third groove 43 is the same as the width of the fourth groove 44. The width of the fourth groove 44 is smaller than the diameter of the first groove 41, and the diameter of the first groove 41 is smaller than the diameter of the second groove 42. The insertion piece 5 slides and inserts in the limiting groove 4 to limit the screen frame assembly 3 and the shaking screen frame 1.
[0028] In order to fix the screen frame assembly 3 and the shaking screen frame 1, the connector 5 includes a sliding plate 53 that is inserted into the third slot 43. The sliding plate 53 is circular and the top of the sliding plate 53 is fixedly connected to the plug post 51. The diameter of the sliding plate 53 is the same as the diameter of the second slot 42.
[0029] The insertion post 51 extends to the outside of the limiting groove 4 and is fixedly connected to the limiting plate 52. The diameter of the limiting plate 52 is smaller than the diameter of the first groove 41. In use, the sliding plate 53 is inserted into the second groove 42 until the sliding plate 53 is moved into the third groove 43 in the shaking screen frame 1. Then the limiting plate 52 is pushed, so that the insertion post 51 moves from the position of the second groove 42 to the position of the first groove 41 under the action of the sliding plate 53 and the third groove 43, thus fixing the screen frame assembly 3 and the shaking screen frame 1. Afterwards, when the shaking component of the screen frame assembly 3 shakes at the position of the shaking screen frame 1, the insertion part 5 will shake at the position of the first groove 41. However, the shaking frequency is controllable. The fourth groove 44 is designed in an "L" shape, which requires horizontal movement and then vertical upward movement. However, the shaking of this device is not enough to produce such a large displacement. At the same time, the insertion and fixing reduces the threaded connection between the screen frame assembly 3 and the shaking screen frame 1, reducing the probability of loosening due to threaded shaking.
[0030] The sieve frame assembly 3 includes a storage frame 31 inserted into the vibrating sieve frame 1. The top of the storage frame 31 extends outside the vibrating sieve frame 1. The top view of the top of the storage frame 31 is designed in a "hui" character shape. The limiting groove 4 is provided on the storage frame 31. The top of the storage frame 31 designed in a "hui" character shape enables the limiting groove 4 on the vibrating sieve frame 1 and the storage frame 31 to be aligned without an additional positioning structure when the vibrating sieve frame 1 and the storage frame 31 are inserted into each other.
[0031] The storage frame 31 is designed with a second discharge port 33 and a first discharge port 32. The second discharge port 33 and the first discharge port 32 are respectively arranged on both sides of the storage frame 31. The lowest point of the first discharge port 32 is higher than the highest point of the second discharge port 33. The first discharge port 32 is used for larger tea leaves after sieving, and the storage frame 31 is used to collect smaller tea leaves after sieving.
[0032] The first discharge port 32 is inserted into the partition plate 22. The bottom of the partition plate 22 abuts against the inner bottom of the storage frame 31, and the first discharge port 32 abuts against the partition plate 22.
[0033] The effect achieved by the entire second embodiment is as follows: Insert the sliding plate 53 into the second slot 42 until the sliding plate 53 is displaced into the third slot 43 inside the vibrating sieve frame 1, and then push the limiting plate 52, so that the inserting column 51 moves from the position of the second slot 42 to the position of the first slot 41 under the action of the sliding plate 53 and the third slot 43, and the sieve frame assembly 3 and the vibrating sieve frame 1 can be fixed. After that, when the vibrating component at the position of the vibrating sieve frame 1 where the sieve frame assembly 3 is located vibrates, the inserting part 5 will shake at the position of the first slot 41, but the vibration frequency is controllable, and the fourth slot 44 is designed in an "L" shape, which requires horizontal and then vertical upward movement, and the vibration of this device is not sufficient to generate such a large displacement. At the same time, the inserting and fixing reduces the threaded connection between the sieve frame assembly 3 and the vibrating sieve frame 1, reducing the probability of loosening due to threaded vibration. At the same time, the top of the storage frame 31 designed in a "hui" character shape enables the limiting groove 4 on the vibrating sieve frame 1 and the storage frame 31 to be aligned without an additional positioning structure when the vibrating sieve frame 1 and the storage frame 31 are inserted into each other. During the sieving operation, the first discharge port 32 is used for larger tea leaves after sieving, and the storage frame 31 is used to collect smaller tea leaves after sieving.
[0034] Embodiment Three: As Figure 1-5 shown, a tea vibrating sieve device includes the vibrating sieve frame 1 and the above-mentioned sieve mesh assembly. A feed plate 11 is detachably connected to one end face of the vibrating sieve frame 1. Tea enters the interior of the storage frame 31 inside the vibrating sieve frame 1 through the feed plate 11. A support frame 12 is detachably connected to the bottom of the vibrating sieve frame 1. The support frame 12 is used to support the vibrating sieve frame 1 and the sieve frame assembly 3.
[0035] The effect achieved by the entire third embodiment is that the tea leaves enter the inside of the storage box 31 in the shaking sieve box 1 through the feeding plate 11, are sieved at the position of the sieve mesh 24, and the sieved tea leaves will be discharged through the first discharge port 32 and the storage box 31, realizing the tea sieving operation of the entire device.
[0036] Working principle: When using this sieve mesh assembly and tea leaf shaking sieve device, an external power supply is connected. First, before use, the sieving component 2 and the sieve frame component 3 are assembled. Since the limiting groove 4 and the mounting plate 21 are designed at a 90° angle, the mounting plate 21 is connected to the sieve frame component 3 by bolts. The sieve mesh 24 is a sieve plate for sieving tea leaves. At the same time, the discharge plate 23 and the sieve mesh 24 are designed in an inclined plane to increase the discharge speed and prevent tea leaves from accumulating at the discharge plate 23 and rebounding to the surface of the sieve mesh 24 again. The protruding part of the partition plate 22 will abut against the bottom of the first discharge port 32, and the part located inside the sieve frame component 3 will abut against the bottom of the sieve frame component 3, increasing the overall support force of the sieving component 2. At the same time, the two sides of the sieve mesh 24 and the discharge plate 23 are the same as the internal length of the sieve frame component 3, which will further increase the support force between the sieving component 2 and the sieve frame component 3, reduce the shaking amplitude of the sieving component 2 after being stressed, and the protruding part at the top of the partition plate 22 extends outside the first discharge port 32, further reducing the probability of the sieving component 2 and the sieve frame component 3 falling off. Then, a shaking component is installed outside the shaking sieve box 1 to shake the shaking sieve box 1, the sieve frame component 3 and the sieving component 2. The shaking component at least includes one vibration motor. The vibration motor is controlled to operate by power supply, shaking the sieve frame component 3 and the sieving component 2 for shaking sieving. The tea leaves enter the inside of the storage box 31 in the shaking sieve box 1 through the feeding plate 11, are sieved at the position of the sieve mesh 24, and the sieved tea leaves will be discharged through the first discharge port 32 and the storage box 31, realizing the tea sieving operation of the entire device;
[0037] Secondly, insert the sliding plate 53 into the second slot 42 until the sliding plate 53 is displaced into the third slot 43 in the shaking sieve box 1, and then push the limiting plate 52, so that the inserting column 51 moves from the position of the second slot 42 to the position of the first slot 41 under the action of the sliding plate 53 and the third slot 43, and the sieve frame component 3 and the shaking sieve box 1 can be fixed. Then, when the shaking component at the position of the sieve frame component 3 and the shaking sieve box 1 shakes, the inserting part 5 will shake at the position of the first slot 41, but the shaking frequency is controllable. And the fourth slot 44 is designed in an "L" shape, which requires horizontal and then vertical upward movement, and the shaking of this device is not enough to generate such a large displacement. At the same time, the inserting fixation reduces the threaded connection between the sieve frame component 3 and the shaking sieve box 1 and reduces the probability of the thread shaking and loosening. At the same time, the top of the storage box 31 designed in a "hui" character shape makes it unnecessary for an additional positioning structure when the storage box 31 and the shaking sieve box 1 are inserted, and the limiting grooves 4 on the shaking sieve box 1 and the storage box 31 can be aligned, and finally the work of this sieve mesh assembly and tea leaf shaking sieve device is completed.
