[0028] Embodiment:

[0029] Please refer to Figure 1 and Figure 2 As shown, this embodiment provides a glutinous rice screening machine, including: a support base 10, a transmission assembly, a plurality of sieve meshes 102, and an adjustment assembly. The support base 10 is provided with a discharge port 101; the transmission assembly is rotatably installed on the support base 10; a plurality of sieve meshes 102 are all arranged in contact with the transmission assembly, and the sieve meshes 102 reciprocally slide relative to the support base 10 along a first preset direction; the adjustment assembly is arranged in contact with the transmission assembly, is rotatably installed on the support base 10, and drives the adjustment assembly to slide along the first preset direction towards or away from the transmission assembly.

One end is connected to the discharge port 101, and the other end is opened on the upper surface of the support base 10 and is located directly below the sieve mesh 102. The first preset direction is the X direction.

The plurality of sieve meshes 102 are respectively in contact with the transmission component in two upper and lower layers. The upper sieve mesh 102 is mainly used to screen out the broken rice and impurities, and the second sieve mesh 102 is mainly used to screen out the impurities and output them into the output channel of the support base 10. The impurities and small particles are separated from the discharge port 101. The upper sieve mesh 102 retains the glutinous rice with plump and complete grains, and the lower sieve mesh 102 retains the broken rice, which are respectively used in various production scenarios. Moreover, the vibration along the first preset direction can effectively reduce the waste caused by the breakage during the glutinous rice screening process, improve the retention rate and utilization rate of the raw materials by the equipment, and improve the screening accuracy.

[0031] Further, in some embodiments of this embodiment, as Figures 1 to 5 shown, the transmission component includes: a rotating shaft 21, a driving disk 22, and a connecting rod 231. A rotating shaft hole is provided on the support base 10, and the rotating shaft 21 is rotatably installed in the rotating shaft hole. A first limiting groove 211 is provided on the rotating shaft 21, and a rotating hole 212 is provided in the first limiting groove 211; a plurality of sieve meshes 102 are all clamped with the driving disk 22. The driving disk 22 is provided with a second limiting groove 221, which abuts against the bottom surface of the first limiting groove 211. A positioning hole 222 corresponding to the rotating hole 212 is provided on the driving disk 22; the connecting rod 231 is inserted into the positioning hole 222 and the rotating hole 212 to limit the sliding of the driving disk 22 relative to the first limiting groove 211.

[0032] In this embodiment, as Figure 5 shown, a rotating shaft hole for supporting the rotating shaft 21 is provided on the support base 10. A support element such as a bushing or a bearing is also installed between the rotating shaft 21 and the rotating shaft hole. The first limiting grooves 211 are symmetrically provided on the circumferential side of the rotating shaft 21, corresponding to the second limiting grooves 221 on the driving disk 22, and the rotating holes 212 and the positioning holes 222 correspond to each other. The connecting rod 231 is installed in the rotating hole 212 and the positioning hole 222. The connecting rod 231 is threadedly connected to the driving disk 22. The connecting rod 231 is specifically a threaded column with threads provided at both ends, and the threading directions of the two sections should be the same. The middle section of the connecting rod 231 abuts against the inner wall of the rotating hole 212, and both the driving disk 22 and the connecting rod 231 rotate around the central axis of the rotating hole 212.

[0033] Further, in some embodiments of this embodiment, as Figure 1 、 Figure 2 andFigure 3 As shown in the figure, the device further includes: a support rod 103 and a driving block 104. The support rod 103 is installed on the screen 102. A sliding hole is provided on the support seat 10, and the support rod 103 is slidably installed in the sliding hole along the extending direction of the sliding hole; the driving block 104 is installed on the support rod 103. A first clamping groove 223 is provided on the driving disk 22, and the driving block 104 abuts against the inner wall of the first clamping groove 223 and slides relative to the first clamping groove 223.

[0034] In this embodiment, as Figure 2 shown, the support rod 103 is a sliding track, and the sliding hole limits the support rod 103 to reciprocate along a first preset direction. The support rod 103 is installed at both ends of the screen 102 and is respectively connected to the support platforms on both sides of the support seat 10; as Figure 3 shown, the driving block 104 is installed on the support rod 103. A first clamping groove 223 distributed circumferentially is provided on the circumferential side of the driving disk 22. The first clamping groove 223 is an annular groove. The driving block 104 has a spherical surface. The driving block 104 partially extends into the first clamping groove 223. By rotating the rotating shaft 21, the driving disk 22 is driven to rotate around the central axis of the rotating shaft 21 to drive the driving block 104 to continuously slide in the first clamping groove 223, and can simultaneously drive the two screens 102 to reciprocate at the same time, improving the screening efficiency of the device.

[0035] Furthermore, in some implementation manners of this embodiment, as Figures 1 to 5 shown, the adjusting assembly includes: a sliding disk 31, a push rod 32, a rotating wheel 33, and a driving rod 34. The sliding disk 31 is slidably installed on the rotating shaft 21. A limiting groove 311 and a second clamping groove 312 are provided on the sliding disk 31. The limiting groove 311 extends along the axial direction of the sliding disk 31, and the inner wall of the limiting groove 311 abuts against the rotating shaft 21; one end of the push rod 32 is threadedly connected to the support seat 10, and one end of the push rod 32 abuts against the second clamping groove 312; the rotating wheel 33 is installed on the other end of the push rod 32; one end of the driving rod 34 is rotatably connected to the driving disk 22, and the other end is rotatably connected to the sliding disk 31.

[0036] In this embodiment, as Figure 5 shown, the limiting groove 311 is a key groove, and the rotating shaft 21 and the sliding disk 31 are connected by a spline key to limit the rotation of the sliding disk 31 relative to the central axis of the rotating shaft 21; as Figure 4 shown, rotating supports are installed on both the driving disk 22 and the sliding disk 31. Both ends of the driving rod 34 are respectively rotatably installed in the two rotating supports, and the driving rod 34 rotates relative to the driving disk 22 and the sliding disk 31 through a shaft-hole connection to improve the transmission efficiency.

[0037] Furthermore, in some implementation manners of this embodiment, as Figures 1 to 5As shown, there is an angle with adjustable size between the central axis of the driving disk 22 and the central axis of the rotating shaft 21. The driving push rod 32 slides along the axial direction to change the size of the angle, so as to change the vibration amplitude of the plurality of sieve meshes 102.

[0038] In this embodiment, as Figure 4 shown, the central axis of the sliding disk 31 coincides with the central axis of the rotating shaft 21. The sliding disk 31 slides relative to the axial direction of the rotating shaft 21 to push the driving disk 22 to rotate around the rotating shaft 21, so as to change the size of the angle between the central axis of the rotating shaft 21 and the central axis of the driving disk 22, so as to change the swing amplitude of the driving disk 22 as the driving disk 22 rotates with the rotating shaft 21, and further change the amplitude of the reciprocating motion of the driving block 104, so as to control the vibration frequency of the sieve mesh 102. Specifically, the larger the angle, the greater the stroke of the reciprocating motion of the driving block 104, so that the vibration amplitude of the sieve mesh 102 is greater.

[0039] Further, in some implementation manners of this embodiment, as Figure 3 、 Figure 4 and Figure 5 shown, the transmission assembly further includes: a driving member 232 and a connecting member 24. The driving member 232 is installed on the support base 10; one end of the connecting member 24 is in transmission connection with the driving member 232, and the other end is installed on the rotating shaft 21.

[0040] In this embodiment, as Figure 5 shown, the driving member 232 may specifically be a servo motor, and the connecting member 24 may specifically be a belt pulley and a belt. The belt pulleys in the connecting member 24 are respectively installed on the rotating shaft 21 and the driving member 232 for transmitting the rotation of the driving member 232, so as to drive the rotation of the rotating shaft 21.

[0041] Further, in some implementation manners of this embodiment, as Figure 1 、 Figure 2 and Figure 3 shown, the device further includes: a mask 105. The mask 105 covers the support base 10, and a feeding port 106 is opened on the mask 105.

[0042] In this embodiment, as Figure 1 shown, a feeding port 106 opposite to the sieve mesh 102 is opened on the mask 105 to prevent a large amount of dust generated during the screening process from escaping from the sieve mesh 102, improve the limitation of the device on dust, and thus improve the convenience of use.

[0043] In summary, when using the glutinous rice screening machine to screen glutinous rice, through multiple sieve meshes 102, the glutinous rice is graded and screened multiple times. The intact glutinous rice and broken rice are respectively retained on two different sieve meshes 102, and the impurities in the glutinous rice are uniformly collected and removed through the discharge port 101, improving the retention amount of the glutinous rice screening by the device and reducing the waste of raw materials. By rotating the push rod 32, the push rod 32 is driven to move axially through the thread, driving the sliding disk 31 to move along the axis of the rotating shaft 21. The sliding disk 31 drives the driving rod 34 to push the driving disk 22 to rotate around the central axis of the positioning hole 222, so as to change the included angle between the central axis of the driving disk 22 and the central axis of the rotating shaft 21, and control the vibration amplitude of the sieve mesh 102, improving the applicable range of the device for the production process. The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope recorded in the present invention can easily think of changes or substitutions, which should all be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
