Detailed Implementation

[0014] 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.

[0015] Please see Figure 1-4 This utility model provides an embodiment of a rapid sieving device for flour quality testing, comprising a support platform 1, a support base 8 mounted on the top of the support platform 1, springs 2 mounted on the outer side wall of the support base 8, connecting blocks 17 mounted on the top of each spring 2, a sieving box 3 mounted on the top of each support base 8, and the outer side wall of the sieving box 3 fixed to one side of the connecting block 17. A filter screen 6 is mounted on the top of each sieving box 3, and a discharge hopper 20 is mounted on the bottom of each sieving box 3, with a discharge port 18 at the bottom of each discharge hopper 20. A filter screen 6 is mounted on both sides of the bottom of the discharge hopper 20. Push rod 14, and push block 15 is installed at the bottom of each push rod 14. Rotating rod 12 is movably arranged inside the support platform 1. Servo motor 9 is installed on one side of rotating rod 12. Cam 13 is installed on the outer side wall of rotating rod 12. Vibration motor 7 is installed on one side of each screening box 3 through mounting bracket 5. There are several cams 13 and push blocks 15. There is a one-to-one correspondence between several cams 13 and push blocks 15. There are several springs 2. Several springs 2 are distributed in a ring at equal intervals on the outer side wall of spring 2, so that the three sets of screening boxes 3 can stably perform vibration screening work together. Specifically, such as Figure 1 and Figure 2As shown, when a single sieving box 3 is needed to sieve flour samples, one of the three sieving boxes 3 is selected, and the vibration motor 7 on one side of the sieving box 3 is turned on to make it vibrate for sieving. If multiple flour samples need to be sieved, the servo motor 9 is started. The servo motor 9 drives the rotating rod 12 to rotate, and the rotating rod 12 drives the cam 13 to rotate. The rotation of the cam 13 pushes the push block 15 to move up and down. The up and down movement of the push block 15, through the push rod 14 and the elastic force of the spring 2, pushes the three sieving boxes 3 to work simultaneously, vibrating up and down to sieve the flour samples, thus sieving the three flour samples at one time.

[0016] Both sides of the top of the filter screen 6 are equipped with a bracket 19, and the top of the bracket 19 is equipped with a pull ring 4. The cross-section of the bracket 19 is larger than the cross-section of the screening box 3. The bracket 19 and the screening box 3 form a locking structure, which makes it easy to disassemble the filter screen 6. The filter screen 6 can also be stably installed inside the screening box 3. Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, when disassembling the filter screen 6, hold the pull rings 4 on both sides of the top of the screening box 3 and pull the screening box 3 upwards so that the hanger 19 moves out from the outer wall of the screening box 3, and the filter screen 6 can be taken out from the screening box 3. When installing, align the hanger 19 with the two sides of the screening box 3 and lock them together, so that the filter screen 6 can be installed inside the screening box 3.

[0017] Fixing plates 10 are installed on both sides of the support platform 1. Telescopic cylinders 16 are installed on both sides inside the fixing plates 10. Stabilizing seats 11 are installed at the bottom of the telescopic cylinders 16. There are two sets of stabilizing seats 11. The two sets of stabilizing seats 11 are symmetrically distributed about the central axis of the support platform 1, which provides better stability for the screening device. Specifically, such as Figure 1 and Figure 2 As shown, before the screening device is put into operation, the telescopic cylinders 16 on both sides of the support platform 1 are activated. The telescopic cylinders 16 push the stabilizing seat 11 downward to fit against the placement surface of the screening device, thus supporting the screening device and placing it stably.

[0018] Working principle: Take the sieving device and activate the telescopic cylinders 16 on both sides of the support platform 1. The telescopic cylinders 16 will push the stabilizing seat 11 downwards to fit against the placement surface of the sieving device, thus supporting the sieving device and ensuring its stable placement. When using the device, select the appropriate method according to the number of flour samples to be tested. If multiple flour samples need to be sieved, pour the three flour samples into the three sieving boxes 3 inside the support platform 1, above the filter screens 6. Then, start the servo motor 9 to drive the rotating rod 12 to rotate. The rotation of the rotating rod 12 drives the cam 13 to rotate, and the rotation of the cam 13 pushes the pusher block 15 up and down. When the push block 15 moves up and down, it drives the three sets of sieving boxes 3 to work simultaneously through the spring force of the push rod 14. The up and down movement vibrates and sieves the three sets of flour samples. Under the action of vibration, the flour samples larger than the mesh of the filter screen 6 are discharged through the discharge port 18 at the bottom of the discharge hopper 20, while the flour smaller than the mesh of the filter screen 6 and impurities remain above the filter screen 6. Then, by holding the pull rings 4 on both sides of the top of the sieving box 3 and pulling the filter screen 6 upward, the hanger 19 moves out from the outer wall of the sieving box 3, so that the filter screen 6 can be removed from the sieving box 3. Then, the flour and impurities sieved above the filter screen 6 can be cleaned off.

[0019] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
