[0002] The screening process plays a vital role in the rice processing process. It effectively removes impurities through the screening process, such as small bricks, sand, soil, iron products, etc. that may be mixed in during the growth, harvesting, and drying of rice, ensuring the purity of the rice. In addition, the screening process also has a grading function, which can classify paddy or rice according to particle size and shape, thereby producing a variety of grades of rice products that meet the needs of different consumers.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figures 1 to 4 A blocking-preventing screening device for rice processing comprises a left support 1, a right support 2, a screening structure 3, a feeding structure 4, an blocking-preventing structure 5 and a positioning assembly 6. The surfaces of the left support 1 and the right support 2 are both provided with round holes matching the screening structure 3. The left support 1 and the right support 2 are assembled at both ends of the screening structure 3 through the positioning assembly 6. The feeding structure 4 is assembled on the outer surface of the left support 1. The blocking-preventing structure 5 is assembled between the left support 1 and the right support 2, and the blocking-preventing structure 5 is located above the screening structure 3. The outer surface of the left support 1 is equipped with a power structure, and the power structure drives the screening structure 3 to rotate. A collecting box 7 is assembled between the left support 1 and the right support 2, and the collecting box 7 is located below the screening structure 3.

[0031] The left support 1 and the right support 2 support the screening structure 3. The power mechanism on the left support 1 can drive the screening structure 3 to rotate. The rotation of the screening structure 3 can screen the rice more effectively.

[0032] The feeding structure 4 is used to guide the rice to fall into the screening structure 3 .

[0033] The anti-blocking structure 5 acts on the sieve holes of the screening structure 3 to make the rice stuck in the sieve holes fall off, thereby optimizing the screening structure 3 and preventing it from blocking.

[0034] The anti-blocking structure 5 is located above the screening structure 3 and will not affect the falling and collection of the screened rice.

[0035] The sieved rice will fall into the collecting box 7.

[0036] like Figure 7 and Figure 8 As shown, the anti-blocking structure 5 includes a mounting plate 51 and a nozzle 52. The mounting plate 51 is installed between the left support 1 and the right support 2, and a cavity is opened inside the mounting plate 51. The end of the cavity close to the feeding structure 4 is connected to the external pipeline. The nozzle 52 is evenly fixed on the lower surface of the mounting plate 51, and the nozzle 52 is connected to the cavity. The output end of the nozzle 52 faces the screening structure 3.

[0037] The external pipeline uses a high-pressure gas pipeline, which can provide high-pressure gas to the cavity of the mounting plate 51, and then spray it out from the nozzle 52, generating high-pressure gas to blow toward the sieve holes of the screening structure 3, so that the rice stuck on the sieve holes falls off.

[0038] In actual application, a sensor can be installed on the side of the mounting plate 51 to sense whether the sieve holes are blocked by rice. When blockage occurs, the corresponding nozzle 52 can be controlled to start to complete the anti-blocking and cleaning work.

[0039] Specifically, if Figure 2 As shown, a support plate 11 is fixedly installed on the lower side of the outer surface of the left support 1, and the power structure is assembled on the support plate 11. A fixing rib 14 is fixedly installed between the support plate 11 and the left support 1, and a box body mounting groove 15 is opened on the outer periphery of the outer surface of the left support 1.

[0040] Specifically, if Figure 2 As shown, the power structure includes a motor 12 and a driving gear 13 . The motor 12 is fixedly mounted on the support plate 11 , and the driving gear 13 is fixedly mounted on the output end of the motor 12 .

[0041] like Figure 2 , Figure 4 and Figure 6 As shown, the screening structure 3 includes a cylindrical screen 31, a driven gear 32 and a spiral plate 33. The driven gear 32 is fixedly mounted on the outer surface of one end of the cylindrical screen 31 close to the feed structure 4, and the driven gear 32 is meshed with the driving gear 13. The spiral plate 33 is fixedly mounted on the inner surface of the cylindrical screen 31, and an annular plate 34 is fixedly mounted on the inner surface of the cylindrical screen 31 at the feed end.

[0042] The power of the motor 12 is transmitted to the cylindrical screen 31 through the meshing of the driving gear 13 and the driven gear 32, thereby driving the cylindrical screen 31 to rotate, thereby completing the screening of the rice.

[0043] The spiral plate 33 installed in the cylindrical screen 31 will rotate together with the cylindrical screen 31, thereby driving the rice to move in the cylindrical screen 31, avoiding the accumulation of rice and making it dispersed, thereby improving the screening effect.

[0044] The length of the screening structure 3 can be adjusted by design, and the spacing of the spiral plates 33 can be adjusted to control the speed at which the rice moves forward.

[0045] The annular plate 34 can prevent the rice from falling into the box body 41 in reverse.

[0046] Specifically, if Figure 5 and Figure 6 As shown, positioning rings 35 are fixedly installed on both sides of the outer surface of the cylindrical screen 31, and the diameter of the positioning ring 35 is larger than the diameter of the circular hole.

[0047] The positioning ring 35 is provided so that the cylindrical screen 31 can be effectively assembled between the left support 1 and the right support 2 .

[0048] Specifically, if Figure 1 and Figure 4 As shown, the feed structure 4 includes a box body 41, a feed piece 42 and a guide pipe 43. The box body 41 is assembled at the box body mounting groove 15. The upper surface of the box body 41 is equipped with the feed piece 42, and the guide pipe 43 is fixedly installed on the lower surface of the feed piece 42, and the outlet end of the guide pipe 43 is located between the annular plate 34 and the spiral plate 33. A pipeline mounting hole 44 is opened on the upper surface of the box body 41, and the external pipeline is connected to the mounting plate 51 after passing through the pipeline mounting hole 44.

[0049] The rice is put into the feeding piece 42 and then falls into the cylindrical screen 31 along the guide tube 43. The design of the outlet end of the guide tube 43 allows the rice to fall directly into the range of the spiral plate 33 in the cylindrical screen 31, and then the rice can be effectively dispersed under the action of the spiral plate 33, thereby improving the screening efficiency and reducing the possibility of clogging of the screen holes.

[0050] Specifically, if Figure 4 , Figure 7 and Figure 8 As shown, rectangular protrusions are integrally formed at both ends of the mounting plate 51, rectangular holes are opened on the surfaces of the left support 1 and the right support 2, and the rectangular protrusions are inserted into the rectangular holes, and a cover body 53 is fixedly installed on the side surface of the mounting plate 51, and the cover body 53 covers the outside of the screening structure 3.

[0051] The cross-sectional area of ​​the mounting plate 51 is larger than the rectangular hole, so after the rectangular protrusion is provided, the mounting plate 51 can be effectively installed between the left support 1 and the right support 2 .

[0052] The cover 53 can protect the cylindrical screen 31 and prevent the rice sieved from the side of the cylindrical screen 31 from falling outside, thereby ensuring that all the sieved rice can fall into the collection box 7.

[0053] Specifically, if Figure 1 and Figure 4As shown, the positioning assembly 6 includes a threaded column 61 and a threaded ring 62. Positioning holes are provided on the surfaces of the left support 1 and the right support 2, and the threaded column 61 passes through the positioning holes. A cylindrical stopper is integrally formed at one end of the threaded column 61, and the threaded ring 62 is screwed to the other end of the threaded column 61.

[0054] With the cooperation of the positioning ring 35 , the mounting plate 51 and the positioning assembly 6 , the installation and stabilization of the left support 1 , the right support 2 , the screening structure 3 and the anti-blocking structure 5 are effectively achieved.

[0055] Specifically, if Figure 1 , Figure 4 and Fig. 9 As shown, the left and right surfaces of the collecting box 7 are integrally formed with positioning rods 71, the inner surfaces of the left support 1 and the right support 2 are provided with rectangular grooves, and the positioning rods 71 ​​are inserted into the rectangular grooves, and the side surface of the collecting box 7 is provided with a discharge port 72, and the lower surface of the inner cavity of the collecting box 7 is a guiding inclined surface, and the side surfaces of the inner cavity of the collecting box 7 are located on both sides of the discharge port 72 and integrally formed with guide baffles 73, and the inner surface of the guide baffle 73 is an inclined surface, and the guiding inclined surface and the inclined surface are both facing the discharge port 72.

[0056] The guide inclined surface and the guide baffle 73 are designed so that the rice falling into the collection box 7 can be moved to the discharge port 72 by gravity. The outer side of the discharge port 72 can be directly connected to other collecting equipment or connected through a pipeline to achieve continuous screening and collection of rice.

[0057] Specifically, the outer surface of the right support 2 is equipped with a recovery box 8 .

[0058] The screened impurities will eventually fall into the recovery box 8 under the action of the spiral plate 33.

[0059] In actual applications, the cylindrical screen 31 can be replaced by selecting screens with different sizes of mesh holes to achieve different degrees of screening. When the mesh hole size is smaller than the size of rice, the functionality of the collecting box 7 and the recycling box can be adjusted, that is, the collecting box collects sand, soil, small impurities and other materials, while the recycling box completes the collection of rice.

[0060] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present invention. As long as these changes do not deviate from the concept of the present invention, they all belong to the protection scope of the present invention.
