Description
Technical Field
[0001] The invention relates to the field of rice processing, and more specifically to rice processing equipment and a rice processing technology. Background Art
[0002] Rice is a finished product made from rice grains after cleaning, husking, milling, and finishing. The embryo and endosperm of rice contain nearly 64% of rice nutrition and more than 90% of the nutrients required by the human body. It is the main food of people in the south. The rice processing process is the process of removing the husk and cortex of rice. Rice grains are composed of husk, cortex, embryo and endosperm. The purpose of rice processing is to separate the endosperm from other parts with the minimum degree of crushing to make rice with better edible quality. The rice processing process will produce impurities such as husk and fine sand. When separating, drum separation equipment is generally used to make the rice roll in it to separate impurities. However, during the screening process of these equipment, the rice is easy to slide along the drum wall. When there is a lot of accumulated rice, it is not easy to turn it over, which makes the screening speed slow. Summary of the invention

[0007] The processing technology of the rice processing equipment comprises the following steps;
[0008] S1: placing the rice to be screened between multiple filter plates;

DETAILED DESCRIPTION
[0022] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0023] The present invention will be further described below in conjunction with the accompanying drawings.
[0024] like Figure 1 and Figure 2 , in order to solve the problem of increasing rice screening efficiency.
[0025] The square rod 101 is welded to the middle section of the rotating shaft 11, and the two side plates 102 are welded to the two sides of the rotating shaft 11. Each side plate 102 is provided with a plurality of straight grooves 103. A sliding rod 104 is slidably connected between each two corresponding straight grooves 103 on the two side plates 102, and each filter plate 105 is rotatably connected between the two sliding rods 104.
[0026] Each straight groove 103 is located on the radius line of the side plate 102, and two adjacent straight grooves 103 are arranged alternately in height. When the rice is screened, the rice is placed between the multiple filter plates 105, and then the rotating shaft 11 is driven to rotate, thereby driving the square rod 101 to rotate, thereby driving the side plate 102 to rotate, and then driving the multiple sliding rods 104 and the filter plates 105 to rotate. The filter plates 105 are provided with multiple through holes so that impurities can pass through, so that the rice can roll therein to screen the impurities therein. While the rotating shaft 11 rotates, the multiple sliding rods 104 are driven to move synchronously back and forth in the straight grooves 103, so that the multiple filter plates 105 can shrink and expand synchronously inwardly, and then in the process of rotation, the space where the rice is located is continuously expanded, so that the rice is repeatedly lifted and dropped, so as to prevent the rice from always sliding against the filter plate, so that the rice grains collide and stir with each other, thereby increasing the turning effect of the rice during the filtering process, and thereby increasing the screening speed of the impurities therein.
[0027] like Figure 3 and Figure 4 , in order to solve the problem of relative transformation between multiple filter plates 105.
[0028] The cover plate 109 is welded on the rotating shaft 11 , the driving plate 106 is rotatably connected between the cover plate 109 and the side plate 102 , the driving plate 106 is processed with an inclined groove 107 corresponding to the straight groove 103 , and the coil spring 109 is welded between the side plate 102 and the driving plate 106 .
[0029] When the rotating shaft 11 rotates, the driving plate 106 and the side plate 102 rotate relative to each other. Initially, the slide bar 104 is located at the end where the inclined groove 107 and the straight groove 103 overlap on the outside. When the driving plate 106 rotates, the inclined groove 107 rotates relative to each other, so that the overlapping part of the inclined groove 107 and the straight groove 103 moves, and then the inclined groove 107 drives the slide bar 104 to move in the straight groove 103 toward the rotating shaft 11, so that the plurality of filter plates 105 and the rotating shaft 11 rotate relative to each other. The drive plate 106 is moved and the distance between the multiple filter plates 105 is reduced at the same time. When the drive plate 106 rotates relative to the side plate 102, the coil spring 109 is compressed. Then, when the multiple filter plates 105 move to the innermost side, the relative rotation between the drive plate 106 and the side plate 102 is stopped, and the compressed coil spring 109 is reset. Similarly, the multiple slide bars 104 are reset, and then the drive plate 106 is intermittently driven to rotate relative to the side plate 102 during the rotation of the rotating shaft 11, thereby achieving the problem of changing the relative positions of the multiple filter plates 105 during the screening process.
[0030] like Figure 4 , to solve the problem of rice falling out of the equipment during screening.
[0031] The fixed end of the first hydraulic rod 111 is fixed to the side plate 102 by screws, and the movable end of the first hydraulic rod 111 is fixed to the slide plate 110 by screws. The slide plate 110 is slidably connected to the square rod 101 and is located between the other side plate 102 and the filter plate 105.
[0032] Initially, the first hydraulic rod 111 is in an extended state. At this time, there is a gap between the slide plate 110 and the filter plate 105, which makes it easy to add rice into the equipment. Then, the first hydraulic rod 111 is driven to contract, thereby driving the slide plate 110 to slide toward the filter plate 105 on the square rod 101, so that it contacts the filter plate 105, and then the shaft 11 is driven to rotate to screen the rice, thereby preventing the rice from falling out of the filter plate 105. After the screening is completed, the first hydraulic rod 111 is driven to extend, and similarly, the slide plate 110 is reset, thereby facilitating the removal of rice from the equipment.
[0033] like Figure 5 , to solve the problem of rotation of the rotating shaft 11.
[0034] The rotating shaft 11 is rotatably connected to the fixing frame 12, the motor 201 is fixed to the fixing frame 12 by screws, the first pulley 202 is key-connected to the output shaft of the motor 201, the second pulley 203 is key-connected to the rotating shaft 11, and the first pulley 202 and the second pulley 203 are connected by a belt.
[0035] When processing is carried out, the driving motor rotates, thereby driving the first pulley 202 to rotate, and then driving the second pulley 203 to rotate through the belt, and then driving the rotating shaft 11 to rotate, so as to achieve the purpose of rice screening. The first pulley 202 is key-connected to the output shaft of the motor 201, and the second pulley 203 is key-connected to the rotating shaft 11. Then, by changing the transmission ratio between the two pulleys, the rotation speed of the rotating shaft 11 is changed, so as to facilitate the processing of different types of rice.
[0036] like Figure 6 , in order to solve the problem of driving the driving plate 106 to rotate relative to the side plate 102 during the screening process.
[0037] The cam 204 is welded on the output shaft of the motor 201 , the lower end of the clamping block 205 is in contact with the cam 204 , and the clamping block 205 is slidably connected to the fixing frame 12 .
[0038] When the motor 201 is working, its output shaft rotates continuously, thereby driving the cam 204 to rotate. Then, when the raised part of the cam 204 rotates upward, the block 205 is pushed up, so that the block 205 contacts the driving plate 106. When the rotating shaft 11 rotates, it drives the side plate 102 to rotate. Due to the existence of the coil spring 108, the driving plate 106 and the following side plate 102 rotate synchronously. Then, when the block 205 moves upward and contacts the driving plate 106, the driving plate 106 is made stationary through friction. At this time, the side plate 102 continues to rotate, thereby achieving the purpose of rotating the driving plate 106 relative to the side plate 102. As the output shaft of the motor 201 continues to rotate, the contact portion between the cam 204 and the block 205 becomes shorter, and then the block 205 drops due to its own gravity and no longer contacts the driving plate 106. Then, the driving plate 106 is driven by the coil spring 108 to rotate and reset.
[0039] like Figure 7 , in order to further increase the screening rate of rice by the equipment.
[0040] One end of the rotating shaft 11 is rotatably connected to the rotating frame 301 in the longitudinal direction, and the rotating frame 301 is rotatably connected to the equipment frame 13 in the transverse direction.
[0041] When rice is added to the device, the rotating frame 301 is driven to rotate, so that the other end of the rotating shaft 11 is lifted, and rice is added between the filter plates 105 from the other end. After the slide plate 110 moves to close the filter plate 105, the rotating shaft 11 is driven to rotate, and the rotating frame 301 is rotated reciprocatingly, thereby driving the fixed frame 12 and the rotating shaft part to rotate as a whole, so that the rice in the filter plate 105 moves in a circular motion while moving along the axial direction, and then moves along a spiral line in the filter plate 105, thereby further increasing the stirring effect on it and increasing the screening rate.
[0042] like Figure 7 , to solve the problem of taking out the rice after screening.
[0043] The push plate 14 is slidably connected to the fixed frame 12 , the middle section of the blanking chute 402 is rotatably connected to the push plate 14 , and a tension spring 401 is welded between the push plate 14 and the fixed frame 12 .
[0044] The diameter of the slide plate 110 is larger than that of the side plate 102, and the part with a larger diameter of the slide plate 11 contacts the inner side of the chute 402. Therefore, when the screening work is performed, the tension spring 401 is in a contracted state, so that the push plate 14 always drives the chute 402 to contact the slide plate 110. When the screening is completed, the first hydraulic rod 111 is driven to extend, thereby driving the slide plate 110 to move outward, and then the slide plate 110 pushes the chute 402 to move outward synchronously, and then the fixed frame 12 is tilted to make the rice in the filter plate 105 slide into the chute 402, and then the chute 402 is tilted to make the rice slide out of the equipment, and the middle section of the chute 402 is rotatably connected to the push plate 14, and the two are interference fit. At the same time, when the slide plate 110 moves, the chute 402 follows and moves synchronously, thereby ensuring that when rice is added, part of the rice when the slide plate 110 just moves and separates from the filter plate 105 is promptly received by the chute 402 to avoid waste.
[0045] like Figure 8 , in order to solve the problem of rotation of the rotating frame 301.
[0046] The slider 302 is slidably connected to the equipment frame 13, the fixed end of the second hydraulic rod 303 is fixed to the equipment frame 13 by screws, the movable end of the second hydraulic rod 303 is fixed to the slider 302 by screws, the rotating wheel 206 is rotatably connected to the fixed frame 12, and the rotating wheel 206 is in contact with the slider 302.
[0047] The slider 302 is a right triangle, and the rotating wheel 206 contacts the hypotenuse of the slider 302. When the rotating wheel 206 is located in the middle of the hypotenuse of the slider 302, the rotating shaft 11 is parallel to the ground. When the second hydraulic rod 303 is extended, the slider 302 is driven to move, and the rotating wheel 206 moves downward along the hypotenuse of the slider 302. Similarly, when the second hydraulic rod 303 is contracted, the slider 302 is driven to move, and the rotating wheel 206 moves upward along the hypotenuse of the slider 302, so that the rotating frame 301 reciprocates.
[0048] like Figure 7 and Figure 8 , which is the problem of taking out the rice in the feeding chute 402.
[0049] The groove shaft 403 is welded on the blanking groove 402 , and the groove shaft 403 is slidably connected to the fixing frame 12 , and the two can rotate relatively, and the push rod 404 is welded on the groove shaft 403 .
[0050] When the rice is taken out, the slider 302 is driven to move, so that one side of the rotating wheel 206 on the fixed frame 12 moves downward, and then the first hydraulic rod 111 is driven to extend, thereby driving the slide plate 110 to move, thereby pushing the chute 402 to move, thereby driving the chute shaft 403 to move, thereby making the top rod 404 contact with the bevel of the slider 302, and then being driven to rotate by the bevel, thereby driving the chute shaft 403 to rotate, and then driving the chute 402 to rotate, so that the rice in the chute 402 slides out of the equipment.
[0051] like Fig. 9 , a processing technology of rice processing equipment, comprising the following steps;
[0052] S1: placing rice to be screened between a plurality of filter plates 105;
[0053] S2: driving the first hydraulic rod 111 to contract, sealing the rice between the filter plates 105;
[0054] S3: The driving motor 201 works and drives the second hydraulic rod 303 to reciprocate and contract to screen out impurities in the rice;
[0055] S4: driving the second hydraulic rod 303 to contract, and then driving the first hydraulic rod 111 to extend, to take out the screened rice.
