Description

Technical Field

[0001] This utility model relates to the field of pollen shaking sieve technology, and in particular to a shaking sieve for processing pollen. Background Technology

[0002] Pollen is the reproductive cell produced by the stamens of plants. Rich in protein, vitamins, minerals, and bioactive components, it is widely used in the food, health product, cosmetic, and pharmaceutical industries. For example, pine pollen and rapeseed pollen can be processed into nutritional supplements with immune-boosting and antioxidant effects. However, freshly collected pollen usually contains impurities (such as fragments of branches and leaves, insect remains, and soil particles), and the pollen particles are uneven in size. Direct use can affect product quality and safety; therefore, a sieving process is necessary to remove impurities and grade the pollen.

[0003] Traditional pollen sieving equipment mainly uses vibrating screens or rotary screens. The screen is driven by a motor to vibrate or rotate, so that pollen particles are separated by passing through screens with different aperture sizes. However, relying solely on a single rotation or vibration action results in poor pollen dispersion, leading to incomplete grading of pollen particles of different sizes and affecting product purity. Utility Model Content

[0004] To address the shortcomings of relying solely on rotation or vibration, which results in poor pollen dispersion and incomplete grading of pollen of different particle sizes, thus affecting product purity, this invention provides a shaking sieve machine for processing pollen. It has the advantages of dual mixing and dispersion, improving pollen sieving efficiency, and solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a shaking sieve machine for processing pollen, including a base, support plates fixedly installed on both sides of the base, a sieve cylinder provided on the inner side of the two support plates, sliders symmetrically fixedly installed on both sides of the sieve cylinder, a slide rail provided in the middle of the corresponding surface of the two support plates, the two sliders respectively slidably installed inside the slide rail, compression springs fixedly installed at the upper and lower ends of the two sliders, the other end of the compression springs respectively fixedly installed inside the slide rail, a protrusion fixedly installed on one side of the upper end of the sieve cylinder, a groove provided on the top of one of the support plates, a drive rod rotatably installed on the inner wall of the groove, and a cam fixedly installed in the middle of the drive rod.

[0006] Each time the cam rotates once, the cam's protrusion contacts the protrusion block and pushes it once, driving the screen cylinder to slide upward along the slide rail and compress the compression spring at the upper end.

[0007] By setting the cam, it contacts the protrusion once per revolution, driving the screen cylinder to slide up and down and compress the spring, causing the screen cylinder to reciprocate to disperse pollen and improve screening efficiency.

[0008] Preferably, a forward and reverse motor is mounted on the upper end of a support plate near the groove, and the output end of the forward and reverse motor is connected to one side of the drive rod via a coupling.

[0009] By using a forward and reverse motor, the drive rod drives the cam to rotate in both directions, so that the screen cylinder continuously receives reciprocating oscillation power, ensuring the continuity of the screening process.

[0010] Preferably, three screens are fixedly installed on the inner wall of the screening cylinder, and the three screens are arranged vertically in a uniform manner with the aperture of the screens decreasing from large to small. A discharge port is provided at the bottom of the screening cylinder.

[0011] By arranging the screens from large to small, pollen can be vertically sieved evenly according to its particle size, and accurately graded through the corresponding discharge hopper and outlet, thus improving sieving efficiency and precision.

[0012] Preferably, three discharge hoppers are fixedly installed on the surface of the screening cylinder, and the three discharge hoppers correspond to three screens. A fixing plate is fixedly installed on the top of the screening cylinder.

[0013] With three discharge hoppers corresponding to the screen, pollen of different particle sizes can be directly discharged from the corresponding discharge hopper after being screened by the screen, realizing the rapid collection of graded pollen and improving screening efficiency.

[0014] Preferably, a rotary motor is installed at the upper end of the fixed plate, and a rotary shaft is installed at the bottom of the fixed plate. The rotary motor is connected to the top of the rotary shaft via a coupling. Multiple stirring rods are fixedly installed on the surface of the rotary shaft, and the bottom of the stirring rods is in contact with the upper end of the screen.

[0015] By using a rotary motor and stirring rod, the rotary motor drives the stirring rod to rotate, which stirs and breaks up the pollen on the screen, preventing clumping and improving screening efficiency and uniformity.

[0016] This utility model has the following advantages:

[0017] 1. By setting a forward and reverse motor to drive the drive rod to rotate, the cam periodically contacts the protrusion, driving the screen cylinder to slide along the slide rail and squeeze the compression spring. After the cam disengages from the protrusion, the compression spring releases its elastic potential energy to drive the screen cylinder to reset, causing the screen cylinder to produce a reciprocating shaking motion. At the same time, the rotating motor drives the rotating shaft and stirring rod to rotate. During the shaking of the screen cylinder, the pollen on the screen is stirred and dispersed simultaneously. The two work together to form a dual mixing and dispersing mechanism of shaking and stirring, so that the pollen particles on the screen undergo vertical vibration dispersion and horizontal stirring and loosening at the same time, effectively breaking the adhesion between particles, avoiding agglomeration and screen blockage, and achieving the effect of efficient screening and precise grading.

[0018] 2. By setting three vertically arranged screens with uniform apertures from large to small on the inner wall of the screening cylinder, and cooperating with the corresponding discharge hopper and bottom discharge port on the surface of the screening cylinder, when pollen enters the screening cylinder, large particles of impurities and pollen are first intercepted by the upper large-aperture screen and discharged through the corresponding discharge hopper. Medium-sized pollen passes through the upper screen and is intercepted by the middle screen and discharged through the middle discharge hopper. Small-sized pollen passes through the middle screen and is further screened by the lower screen. Finally, the fine particles are discharged from the bottom discharge port. This multi-stage screening structure can complete the grading of pollen of different particle sizes in one go, avoiding the cumbersome process of multiple screenings required by traditional equipment, improving processing efficiency, and ensuring the purity and quality of pollen particles at each level.

[0024] 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.

[0025] Please see Figures 1-4A sieving machine for processing pollen includes a base 1, with support plates 2 fixedly installed on both sides of the base 1. A sieving cylinder 3 is provided on the inner side of the two support plates 2. Slider blocks 11 are symmetrically fixedly installed on both sides of the sieving cylinder 3. A slide rail 10 is provided in the middle of the corresponding surface of the two support plates 2. The two sliders 11 are slidably installed inside the slide rail 10, so that the sieving cylinder 3 can slide stably up and down along the slide rail 10 under the action of the drive mechanism. This provides guidance for the reciprocating sieving of the sieving cylinder 3, limits its movement direction, and ensures that it does not deviate or tilt during the sieving process. At the same time, with the elastic action of the compression spring 12, the movement of the sieving cylinder 3 is stable and controllable, improving the stability and reliability of the sieving process.

[0026] Compression springs 12 are fixedly installed at both ends of the two sliders 11. The other ends of the compression springs 12 are fixedly installed inside the slide rails 10. A protrusion 17 is fixedly installed on one side of the upper end of the sieve cylinder 3. The elastic deformation of the spring provides continuous vibration power, so that the sieve cylinder 3 can shake smoothly and have a buffering effect, avoiding pollen damage caused by rigid impact, while enhancing the continuity and uniformity of the sieving process.

[0027] One of the support plates 2 has a groove 13 on its top. A drive rod 15 is rotatably mounted on the inner wall of the groove 13. A cam 16 is fixedly mounted in the middle of the drive rod 15. A forward and reverse motor 14 drives the drive rod 15 to rotate, causing the cam 16 to periodically contact the protrusion 17. This drives the screen cylinder 3 to slide along the slide rail 10 and squeeze the compression spring 12. After the contact is broken, the compression spring 12 releases its elastic potential energy to reset the screen cylinder 3, causing the screen cylinder 3 to oscillate up and down.

[0028] Please see Figures 2-4 When the cam 16 rotates once, the protrusion of the cam 16 contacts the protrusion block 17 and pushes it once, driving the screen cylinder 3 to slide upward along the slide rail 10 and compress the compression spring 12 at the upper end. A forward and reverse motor 14 is installed on the upper end of a support plate 2 near the groove 13. The output end of the forward and reverse motor 14 is connected to one side of the drive rod 15 through a coupling, providing a continuous power source for the reciprocating swaying of the screen cylinder 3, so that the cam 16 can periodically contact and disengage from the protrusion block 17, ensuring that the screen cylinder 3 obtains stable up and down reciprocating motion;

[0029] Three screens 5 are fixedly installed on the inner wall of the screening cylinder 3. The three screens 5 are arranged vertically and evenly from large to small aperture inside the screening cylinder 3. A discharge port is opened at the bottom of the screening cylinder 3. Three discharge hoppers 9 are fixedly installed on the surface of the screening cylinder 3, and the three discharge hoppers 9 correspond to the three screens 5. By setting three screens 5 with vertically arranged screens of evenly small aperture from large to small aperture on the inner wall of the screening cylinder 3, and cooperating with the corresponding discharge hoppers 9 on the surface of the screening cylinder 3 and the discharge port at the bottom, when pollen enters the screening cylinder 3, large particles of impurities and pollen are filtered out. First, the pollen particles are trapped by the upper large-aperture screen 5 and discharged through the corresponding discharge hopper 9. Medium-sized pollen particles are trapped by the middle screen 5 after passing through the upper screen 5 and discharged through the middle discharge hopper 9. Small-sized pollen particles are further screened by the lower screen 5 after passing through the middle screen 5. Finally, the fine particles are discharged from the bottom discharge port. This multi-stage screening structure can complete the grading of pollen particles of different sizes in one go, avoiding the cumbersome process of multiple screenings required by traditional equipment, improving processing efficiency, and ensuring the purity and quality of pollen particles at all levels.

[0030] A fixed plate 4 is fixedly installed on the top of the sieve cylinder 3. A rotary motor 6 is installed on the upper end of the fixed plate 4, and a rotary shaft 7 is installed on the bottom of the fixed plate 4. The rotary motor 6 is connected to the top of the rotary shaft 7 through a coupling. Multiple stirring rods 8 are fixedly installed on the surface of the rotary shaft 7. The bottom of the stirring rods 8 is in contact with the upper end of the screen 5. The rotary motor 6 drives the rotary shaft 7 and the stirring rods 8 to rotate. During the shaking of the sieve cylinder 3, the pollen on the screen 5 is stirred and dispersed simultaneously. The two work together to form a dual mixing and dispersing mechanism of shaking and stirring, so that the pollen particles on the screen 5 simultaneously undergo vertical vibration dispersion and horizontal stirring and loosening, effectively destroying the adhesion between particles, avoiding agglomeration and screen clogging, and achieving the effect of efficient screening and precise grading.

[0031] Working principle: In actual use, the pollen to be processed is first poured into the top of the sieve cylinder 3. The forward and reverse motor 14 is started to drive the drive rod 15 to rotate, which drives the cam 16 to start rotating. When the cam 16 rotates one revolution, its protruding part contacts the protruding block 17 once. At this time, the cam 16 pushes the protruding block 17 through the teeth, so that the sieve cylinder 3 slides upward along the slide rail 10 of the support plate 2. The slider 11 moves upward synchronously in the slide rail 10 and compresses the compression spring 12 at the upper end.

[0032] At this time, the compression spring 12 stores elastic potential energy. When the teeth of the cam 16 disengage from the protrusion 17, the compression spring 12 releases elastic potential energy, causing the screen cylinder 3 to return to its original position. The slider 11 moves down in the slide rail 10 and stretches the compression spring 12 at the lower end. This cycle repeats, causing the screen cylinder 3 to oscillate up and down periodically.

[0033] While the sieve cylinder 3 is shaking, the rotary motor 6 is started, which drives the rotating shaft 7 and the stirring rod 8 fixed on the surface of the rotating shaft 7 to rotate through the coupling. The bottom of the stirring rod 8 is in contact with the upper end of the screen 5. As the rotating shaft 7 rotates, the stirring rod 8 continuously stirs and disperses the pollen on the screen 5.

[0034] The up-and-down shaking of the sieve cylinder 3 causes the pollen particles to jump in the vertical direction and come into full contact with the sieve 5, while the horizontal stirring of the stirring rod 8 breaks the agglomeration of the pollen particles and promotes the particles to be evenly distributed on the sieve 5.

[0035] Under the dual motion action, large particles and pollen with larger diameters are first intercepted by the uppermost large-aperture screen 5 and discharged through the corresponding discharge hopper 9. Pollen particles that fail to pass through the upper screen 5 continue to fall and are screened a second time by the middle screen 5. Pollen that meets the aperture of the middle screen 5 is discharged from the middle discharge hopper 9, while fine pollen particles pass through the middle screen 5 and are further screened by the lowermost screen 5 before being discharged from the discharge port at the bottom of the screening cylinder 3. This process ultimately achieves precise grading of pollen of different particle sizes and removal of impurities.
