[0015] Based on the above rice production, processing and selection equipment, the present invention also proposes a rice production and processing method, comprising the following steps: Step 1: primary screening: the first motor drives the vibrating screen mechanism to eccentrically shake, thereby screening out large debris such as stones in the rice raw material, and then guides the rice raw material after the primary screening to the material separation screen plate in the surrounding edge through the discharge hopper; Step 2: secondary screening: the second motor drives the material separation screen plate to rotate within the surrounding edge, further screening the rice raw material discharged from the discharge hopper, and then screening out the broken rice in the rice raw material; Step three, during the secondary screening process, the induced draft fan operates to absorb the broken rice husks during the discharge process of the discharge hopper and the separation process of the separation screen through the suction force of the airflow generated by the induced draft fan, and store them in the storage room.

[0016] The beneficial effects of the present invention are: The present invention uses the first motor to work and the first sieve mesh to shake to sort out large debris such as stones in the rice raw material. Since the mass of large debris such as stones is larger than that of rice, the large debris such as stones gradually gathers toward the edge of the shaking plate under the action of inertia. After a certain amount of debris is gathered, it is shaken out and discharged from the elastic cloth bag through the gap between the fixed ring and the shaking plate, and stored in the upper sorting bin. The screened rice raw material of the present invention enters the lower sorting bin through the discharge hopper and falls on the second screen. The second screen can screen the rice raw material, so that the incomplete rice grains with smaller size fall and are discharged from the first discharge port. In this process, the second screen is driven by the second motor to rotate, that is, the height of the second screen in the fan-shaped area is gradually reduced, so that the rolling speed of the rice in the fan-shaped area is slowed down, that is, the rolling time of the rice on the second screen is increased, thereby improving the screening effect of the rice. The present invention allows the screened rice to approach the baffle on one side as the second screen rotates, and rolls on the electric heating wire as the height of the fan-shaped area decreases. In this process, the electric heating wire in the baffle is heated and transfers the heat to the heat conducting sheet. The rice that passes through the channel can be dried by the electric heating wire and the heat conducting sheet until the fan-shaped area rotates to the lower position, and is discharged from the discharge port reserved at the bottom of the surrounding edge, and then guided out of the second discharge port through the hopper below. In the secondary screening process of the present invention, the output shaft of the second motor rotates to drive the roller brush to rotate through the meshing action of the second bevel gear and the first bevel gear, thereby rolling the second screen from bottom to top to avoid clogging of the holes of the second screen.

[0021] See also Figure 2 and Figure 3The vibrating screen mechanism 2 includes a fixed ring 21, a plurality of springs 22 arranged in an annular shape are fixed to the periphery of the fixed ring 21, the outer ends of the springs 22 are fixed to the box body 1, a rocking plate 23 is arranged on the inner side of the bottom of the fixed ring 21, a plurality of fixed blocks 25 arranged in an annular shape are fixed to the periphery of the rocking plate 23, and the fixed blocks 25 are fixed to the inner side wall of the fixed ring 21, a first screen 24 is fixed to the inner side of the bottom of the rocking plate 23, a cross rod 26 is fixed to the inner side of the top of the fixed ring 21, a crank 27 is rotatably connected to the center of the cross rod 26, the crank 27 is fixed to the output shaft end of the first motor 3, and the bottom of the rocking plate 23 is fixed to the inner side of the first screen 24. An elastic cloth bag 28 is fixed, and the bottom of the elastic cloth bag 28 is fixed to the outer periphery of the top opening of the discharge hopper 4. The crank 27 is driven to rotate by the first motor 3, and the crank 27 pushes the fixed ring 21 to move eccentrically in the upper sorting bin 11, and then the first screen 24 sorts out large debris such as stones in the rice raw material. Since the mass of large debris such as stones is larger than that of rice grains, the large debris such as stones gradually gathers to the edge of the shaking plate 23 under the action of inertia. After gathering to a certain amount, they are shaken out and discharged from the elastic cloth bag 28 through the gap between the fixed ring 21 and the shaking plate 23, and stored in the upper sorting bin 11.

[0022] See also Figure 2 , Figure 4 and Figure 5 The material separation screen plate 6 includes a second screen 61, which is rotatably arranged in the surrounding edge 5. A plurality of drainage guide components 62 for drying the selected rice raw materials on the second screen 61 are fixed on the upper surface of the second screen 61, and each drainage guide component 62 is rotationally symmetrical about the center of the surrounding edge 5 and the second screen 61. A fixed plate 63 is fixed at the center of the second screen 61, and the fixed plate 63 is fixed to the output shaft end of the second motor 8. A roller brush component 64 for cleaning the second screen 61 under the synchronous drive of the second motor 8 is radially arranged on one side of the bottom of the second screen 61. The bottom of the surrounding edge 5 is not closed, and a material discharge port is formed above the second screen 61. The screened rice raw materials enter the lower sorting bin 12 through the discharge hopper 4 and fall on the second screen 61. Figure 2 and Figure 4 It can be seen that the rice raw materials dropped from the discharge hopper 4 can fall into the fan-shaped area formed by the two discharge guide components 62 at the high places, and the landing point is at the expanded end of the fan-shaped area. Under the action of gravity, the rice raw materials move from the expanded end of the fan-shaped area to the contracted end where the fixed plate 63 is located, and the second screen 61 can screen the rice raw materials, so that the smaller incomplete rice grains are screened and discharged from the first discharge port 15. In this process, the second screen 61 is driven by the second motor 8 to move to the first discharge port 15. Figure 4 The second screen 61 rotates in the direction of the middle arrow, that is, the height of the second screen 61 in the fan-shaped area gradually decreases, so that the rolling speed of the rice in the fan-shaped area is slowed down, that is, the rolling time of the rice on the second screen 61 is increased, thereby improving the screening effect of the rice.

[0023] See also Figure 4 and Figure 6 The drainage assembly 62 includes a baffle 621, which is an arc-shaped structure. A plurality of heat-conducting sheets 622 are fixed on the inner arc surface of the baffle 621. A channel through which the rice with edges can pass is formed between the heat-conducting sheets 622 on the baffle 621. The baffle 621 is embedded with a heating wire 623 distributed corresponding to the channel. As the fan-shaped area rotates, the screened rice can approach the baffle 621 on one side, and roll on the heating wire 623 as the height of the fan-shaped area decreases. In this process, the heating wire 623 in the baffle 621 is heated and the heat is transferred to the heat-conducting sheet 622. The rice that has passed through the channel with edges can be dried by the heating wire 623 and the heat-conducting sheet 622 until the fan-shaped area rotates to a lower position and is discharged from the discharge port reserved at the bottom of the surrounding edge 5, and then is guided out of the second discharge port 16 through the hopper below.

[0024] See also Figure 7 The roller brush assembly 64 includes a roller shaft 641, an external fixed sleeve of the roller shaft 641 is provided with a roller brush 642, one end of the roller shaft 641 is rotatably connected to a first support 643 fixed on the surrounding edge 5, and the other end of the roller shaft 641 is rotatably connected to a second support 644 fixed on the bracket 7, and a first bevel gear 645 is fixed to one end of the roller shaft 641 close to the second support 644, and a second bevel gear 646 meshing with the first bevel gear 645 is fixed to the output shaft of the second motor 8. During the secondary screening and selection process, the output shaft of the second motor 8 can rotate to drive the roller brush 642 to rotate through the meshing action of the second bevel gear 646 and the first bevel gear 645, thereby rolling the brush on the rotating second screen 61 from bottom to top, thereby avoiding clogging of the holes of the second screen 61.

[0025] Furthermore, a guard plate 647 is fixed on the second support 644, and the first bevel gear 645 and the second bevel gear 646 are both located below the guard plate 647. The guard plate 647 blocks the secondary screened rice to prevent it from falling on the first bevel gear 645 and the second bevel gear 646 and affecting the meshing transmission.

[0026] It should be noted that a vent 91 is provided on the partition 9, and a damper 92 is provided in the vent 91. A rotating shaft rotatably connected to the partition 9 is fixed on the top of the damper 92. When the machine is stopped, the damper 92 is closed by gravity. When the machine is turned on, the wind suction generated by the induced draft fan 10 can lift the damper 92 to allow the rice husk to enter the storage chamber. A feed port 13 is provided on the top of the upper sorting bin 11 for adding rice raw materials to be processed. Cleaning ports 14 are provided on both sides of the upper sorting bin 11 for cleaning large debris such as sieved stones. A first discharge port 15 is provided at the bottom of the lower sorting bin 12 for discharging incomplete broken rice. A second discharge port 16 is provided on one side of the bottom of the lower sorting bin 12 for discharging selected rice. A discharge hopper is fixed in the second discharge port 16 for receiving the selected rice sieved by the sorting sieve plate 6.

[0027] A rice production and processing method comprises the following steps: Step 1: primary screening, the first motor 3 drives the vibrating screen mechanism 2 to eccentrically shake, thereby screening out large debris such as stones in the rice raw material, and then guides the rice raw material after the primary screening to the material separation screen plate 6 in the surrounding edge 5 through the discharge hopper 4; Step 2, secondary screening, the second motor 8 drives the material separation screen plate 6 to rotate in the surrounding edge 5, further screening the rice raw material discharged from the discharge hopper 4, and then screening out the broken rice in the rice raw material; Step three, during the secondary screening process, the induced draft fan 10 works to absorb the broken rice husks during the discharge process of the discharge hopper 4 and the separation process of the separation screen plate 6 under the suction of the airflow generated by the induced draft fan 10, and store them in the storage room.

[0028] The working principle and use process of the present invention are as follows: the rice raw material to be processed is added to the first screen 24 of the upper sorting bin 11 through the feed port 13, the crank 27 is driven to rotate by the first motor 3, and the fixed ring 21 is pushed by the crank 27 to move eccentrically in the upper sorting bin 11, and then the large debris such as stones in the rice raw material is sorted by the first screen 24. Since the mass of large debris such as stones is larger than that of rice grains, the large debris such as stones gradually gathers to the edge of the rocking plate 23 under the action of inertia. After gathering to a certain amount, it is shaken out and discharged from the elastic cloth bag 28 through the gap between the fixed ring 21 and the rocking plate 23, and stored in the upper sorting bin 11, and the screened rice raw material enters the lower sorting bin 12 through the discharge hopper 4 and falls on the second screen 61, as shown in FIG. Figure 2 and Figure 4It can be seen that the rice raw materials dropped from the discharge hopper 4 can fall into the fan-shaped area formed by the two discharge guide components 62 at the high places, and the landing point is at the expanded end of the fan-shaped area. Under the action of gravity, the rice raw materials move from the expanded end of the fan-shaped area to the contracted end where the fixed plate 63 is located, and the second screen 61 can screen the rice raw materials, so that the smaller incomplete rice grains are screened and discharged from the first discharge port 15. In this process, the second screen 61 is driven by the second motor 8 to move to the first discharge port 15. Figure 4 The second screen 61 rotates in the direction of the middle arrow, that is, the height of the second screen 61 in the fan-shaped area gradually decreases, so that the rolling speed of the rice in the fan-shaped area is slowed down, that is, the rolling time of the rice on the second screen 61 is increased, thereby improving the screening effect of the rice; As the fan-shaped area rotates, the screened rice can get close to the baffle 621 on one side, and roll on the electric heating wire 623 as the height of the fan-shaped area decreases. In this process, the electric heating wire 623 in the baffle 621 heats the rice and transfers the heat to the heat conductive sheet 622. The rice that has rolled on the edge of the channel can be dried by the electric heating wire 623 and the heat conductive sheet 622 until the fan-shaped area rotates to the lower position and is discharged from the discharge port reserved at the bottom of the surrounding edge 5, and then is led out of the second discharge port 16 through the hopper below. During the above-mentioned secondary screening and selection process, the output shaft of the second motor 8 rotates to drive the roller brush 642 to rotate through the meshing action of the second bevel gear 646 and the first bevel gear 645, thereby brushing the rotating second screen 61 from bottom to top, thereby avoiding clogging of the holes of the second screen 61.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
