Description

Technical Field

[0001] The invention belongs to the technical field of rice screening, and in particular relates to dust removal, drying and screening equipment for rice production. Background Art

[0002] Rice is a food made from paddy rice through processes such as cleaning, husking, milling and finishing. It is very nutritious and is one of the main foods for people in most parts of my country.

[0003] During the rice production and processing process, it is inevitable that there will be impurities such as dust, rice debris, and even gravel. In order to ensure the quality of rice, the rice needs to be screened.

[0004] In the prior art, most of the gravel in the rice is screened out by a screen. In order to improve the screening efficiency and avoid clogging, power is applied to the screen to drive the screen to move. However, during the movement of the screen, fine and light impurities such as dust and debris are still easily mixed in the rice and pass through the screen holes, affecting the screening effect. Summary of the invention

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0041] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0042] like Figure 1 As shown, it is a structural diagram of a rice production dust removal and drying screening device provided by an embodiment of the present invention, and the screening device comprises:

[0043] A housing 1, wherein a dust removal slot 28 is provided on one side of the housing 1;

[0044] A split double-layer sieve plate assembly is installed in the housing 1 and switches between two states: a throwing plate and a sieve plate;

[0045] A linked intermittent pushing and switching assembly is installed in the shell 1, corresponding to the split double-layer screen plate assembly. After pushing the split double-layer screen plate assembly several times for dust removal, the split double-layer screen plate assembly is switched to a switching state, and then the split double-layer screen plate assembly is pushed several times for screening.

[0046] In one embodiment of the present invention, the rice production dust removal, drying and screening equipment is provided with a split double-layer sieve plate assembly and a linkage intermittent push-top and switch assembly to address the problems raised in the prior art, wherein the split double-layer sieve plate assembly has two states. In the throwing plate state, no screening work is performed. The linkage intermittent push-top and switch assembly is used to apply force to drive it to swing, thereby driving the rice to be thrown up, and dust removal is performed during the throwing process. Dust can be blown out from the dust removal slot 28. After several times, the linkage intermittent push-top and switch assembly can drive the split double-layer sieve plate assembly to switch to the sieve plate state, and the linkage intermittent push-top and switch assembly continues to apply force. Rice can be screened in this process, and qualified rice falls to the bottom of the shell 1 (the bottom of the shell 1 can be set to a funnel shape to facilitate rice discharge).

[0047] like Figure 2 , Figure 5 As shown, as a preferred embodiment of the present invention, the split double-layer sieve plate assembly includes:

[0048] A sieve plate 2 is movably mounted in the housing 1;

[0049] Sieve plate 2 3 is connected with sieve plate 1 2 in a limited sliding manner. Sieve plates 1 2 and 2 3 are respectively provided with sieve holes. The sieve holes on sieve plates 1 2 and 2 3 are staggered or correspond to each other, thereby driving the split double-layer sieve plate assembly to be in a throwing plate state or a sieve plate state.

[0050] The sieve plate 2 is rotatably installed in the shell 1 through a movable shaft 29, and a baffle is provided in the shell 1 to prevent the sieve plates 1 2 and 2 3 from overturning, and the edges on both sides of the sieve plate 2 are provided with flexible protective belts connected to the inner wall of the shell 1 to prevent the rice from spilling during the throwing process. The sieve hole diameters on the sieve plates 1 2 and 2 3 are selected according to the screening requirements. In the initial state, the sieve holes on the sieve plates 1 2 and 2 3 are staggered with each other. At this time, the sieve plates 1 2 and 2 3 constitute a throwing plate, and the rice will not be screened. When the linked intermittent pushing and switching assembly pushes the sieve plate 2 3 to drive the sieve plate 2 3 and the sieve holes on the sieve plate 2 to correspond, the sieve plate 1 2 and the sieve plate 2 3 constitute a sieve plate, and screening can be carried out.

[0051] like Figures 2 to 3 As shown, as another preferred embodiment of the present invention, limit lock sliders 4 are provided on both sides of the sieve plate 2, and a limit lock groove 5 is provided on the sieve plate 1 2, and the sieve plate 2 3 is connected to the sieve plate 1 2 by sliding and clamping the limit lock sliders 4 and the limit lock groove 5.

[0052] The limit lock slider 4 is clamped in the limit lock slot 5 to ensure that the sieve plate 1 2 and the sieve plate 2 3 can be connected together, and at the same time, the sieve plate 2 3 and the sieve plate 1 2 can move relative to each other to switch states.

[0053] like Figures 2 to 4 As shown, as a preferred embodiment of the present invention, the linkage intermittent ejection and switching assembly includes:

[0054] A driving device 6 is installed outside the housing 1;

[0055] A driving intermittent gear 9 is drivingly connected to the output end of the driving device 6;

[0056] A dial wheel 7 is connected to the driving intermittent gear 9, and a dial plate 8 is provided on the dial wheel 7;

[0057] Gear 12 is located on one side of the driving intermittent gear 9 and continuously meshes with the teeth on the driving intermittent gear 9. When the driving intermittent gear 9 rotates to the toothless edge and cooperates with gear 12, it drives gear 12 to rotate several full circles. A reciprocating ejection assembly is installed on the gear 12;

[0058] The second gear 13 is located at one side of the first gear 12 and is continuously meshed with the first gear 12. The second gear 13 is connected with a dust blowing assembly.

[0059] Starting the driving device 6 can drive the driving intermittent gear 9 to rotate, and the driving intermittent gear 9 can drive the gear 12 to rotate, and the gear 12 can drive the gear 2 13 to rotate. At the same time, the size design of the driving intermittent gear 9 and the gear 12 satisfies that the driving intermittent gear 9 can drive the gear 12 to rotate several full circles in the period from the start of the rotation of the driving intermittent gear 9 to the rotation of the toothless edge and the gear 12, and the dial plate 7 rotates to the dial plate 8 to cooperate with the sieve plate 2 3, and a thrust can be applied to the sieve plate 2 3. Under this premise, the early stage is the dust removal stage, and the starting driving device 6 drives the driving intermittent gear 9 to rotate, and then drives the gear 12 to rotate. The gear 12 applies a thrust to one side of the sieve plate 2 3 through the reciprocating push-up assembly, driving the sieve plates 1 2 and sieve plates 2 3 to swing, and the rice is thrown up. At the same time, the gear 2 13 drives the dust blowing assembly to start, which can drive light impurities in the rice, such as dust, debris, etc., to be blown out of the rice, thereby achieving the purpose of dust removal.

[0060] When the driving intermittent gear 9 rotates to the toothless edge and matches with the gear 12, it is the switching stage. At this time, the gear 12 stops rotating, the sieve plate 1 2 and the sieve plate 2 3 restore the balance and no longer swing, and the paddle plate 8 moves to apply thrust to the sieve plate 2 3, driving the sieve plate 2 3 to move, and the sieve holes on the sieve plate 2 3 correspond to the sieve holes on the sieve plate 1 2 one by one, wherein the paddle plate 8 can be made of soft materials such as rubber, etc., which can not only realize the paddle movement, but also will not cause wear to the sieve plate 2 3;

[0061] The intermittent gear 9 is driven to continue to rotate. At this time, it is the screening stage. The intermittent gear 9 is driven to re-engage with the gear 12, driving the gear 12 to rotate. The gear 12 applies a thrust to one side of the sieve plate 2 3 through the reciprocating push-up assembly, driving the sieve plates 1 2 and 2 3 to swing, and the rice is thrown up, thereby improving the screening efficiency.

[0062] In order to improve the stability of the force applied to sieve plate 1 2 and sieve plate 2 3, the dial wheel 7 and the driving intermittent gear 9 can be symmetrically arranged in a group, and the two driving intermittent gears 9 are connected by a linkage shaft 10. A group of gear 12 can also be correspondingly arranged, wherein gear 1 12 and gear 2 13 on one side are installed on mounting seat 1 11, and gear 1 12 on the other side is installed on mounting seat 3 27.

[0063] like Figure 4As shown, as a preferred embodiment of the present invention, the reciprocating ejection assembly includes:

[0064] A crank disc 14 is fixedly connected to the gear 12, and a hinge column 19 is provided at the edge of the crank disc 14;

[0065] A reciprocating member 15 is vertically slidably mounted inside the housing 1 via a linear stopper 17, and a driving hammer 16 is provided on the reciprocating member 15 corresponding to the split double-layer sieve plate assembly;

[0066] A hinged column 20, mounted on the reciprocating member 15;

[0067] The connecting rod 18 has one end movably hinged to the hinge column 19, and the other end movably hinged to the hinge column 20. When the crank disc 14 rotates, the connecting rod 18 drives the reciprocating member 15 to perform reciprocating pushing motion, driving the split double-layer screen plate assembly to swing, applying a throwing force to the rice to remove dust or screen it. The rice comes into contact with the air during the throwing process, and the drying process is completed at the same time.

[0068] Gear 12 drives the crank disc 14 to rotate. During the rotation, the crank disc 14 applies a reciprocating push-pull force to the reciprocating member 15 through the connecting rod 18, thereby driving the driving hammer 16 to push upward reciprocatingly (under the action of the linear limit block 17, the driving hammer 16 is limited to reciprocating motion in a vertical state), thereby reciprocatingly applying force to the screen plate 2 3, driving the screen plates 1 2 and 2 3 to swing reciprocatingly.

[0069] like Figure 2 As shown, as a preferred embodiment of the present invention, the dust blowing assembly includes:

[0070] The rotating wheel 1 21 is mounted on the housing 1 and fixedly connected to the gear 2 13;

[0071] The second rotating wheel 22 is installed on the housing 1, and a transmission belt 23 is installed between the first rotating wheel 21 and the second rotating wheel 22;

[0072] The fan 24 is installed inside the housing 1 and is fixedly connected to the second rotating wheel 22 to separate light impurities from the thrown rice.

[0073] Gear 2 13 drives rotating wheel 1 21 to rotate, and then drives rotating wheel 2 2 to rotate through transmission belt 23, thereby driving fan 24 to rotate, and utilizing wind power to perform dust removal operation. The specific number of fans 24 can be increased or decreased according to needs.

[0074] like Figure 5 As shown, as a preferred embodiment of the present invention, the split double-layer sieve plate assembly includes a reset assembly for driving the sieve plate 2 3 to reset to the original position;

[0075] Wherein, the reset component comprises:

[0076] A second mounting seat 25, mounted on one end of the sieve plate 1 2;

[0077] The electric push rod 26 is mounted on the second mounting seat 25 , and the driving end of the electric push rod 26 corresponds to the second sieve plate 3 .

[0078] After a dust removal and screening process is completed, the electric push rod 26 is started to extend, and a thrust is applied to the sieve plate 2 3 to drive the sieve plate 2 3 to return to the original state, so as to facilitate the next operation.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
