Description

Technical Field

[0001] The present invention relates to a rice milling machine, and particularly to a rice milling machine for rice processing. Background Art

[0002] Rice, also known as paddy rice, is a food made from paddy after processes such as cleaning, hulling, milling, and finished product finishing. Rice is the main food for people in most parts of China, so rice is also one of the important grain crops in China. To make standard rice, a series of processing is required. After the paddy is filtered for impurities and air-dried multiple times, the outer hull needs to be removed. After the outer hull is removed, there is still a layer of bran on the surface of the brown rice. Then, a rice milling machine is needed to polish off the bran on the surface of the brown rice. The polished-off bran is the bran powder. After polishing, the rice changes from brown rice to white rice, and after further polishing, it becomes pearl rice, which is the semi-finished product.

[0003] When the traditional rice milling machine polishes brown rice, the polished bran powder will accumulate in the tooth holes of the traditional rice milling machine. Long-term accumulation of bran powder is likely to block the tooth holes, making it impossible for the bran powder to be discharged smoothly from the tooth holes. At the same time, when the bran powder splashes, it scatters everywhere and is likely to accumulate in the corners of the parts of the traditional rice milling machine, making it difficult to collect the bran powder centrally. Therefore, we urgently need a rice milling machine for rice processing that can scrape off the bran powder accumulated on the holes and also scrape off the bran powder accumulated in the corners, facilitating the centralized collection of bran powder. Summary of the Invention

[0004] To overcome the problem that long-term accumulation of bran powder is likely to block the tooth holes and at the same time the bran powder scatters everywhere when it splashes, the present invention provides a rice milling machine for rice processing that can scrape off the bran powder accumulated on the holes and also scrape off the bran powder accumulated in the corners, facilitating the centralized collection of bran powder.

The bran powder wrapping housing 54 is connected to the outside of the rice milling cylinder 53 by bolts. The bran powder wrapping housing 54 is used to prevent bran powder from splashing. The power shaft 52 passes through the lower part of the rice milling cylinder 53. The inclined frame 55 is connected to the inner side of the middle part of the triangular support 1 by bolts. The inclined frame 55 is obliquely arranged. The inclined frame 55 is used to guide the flow of bran powder. The soft aluminum plate 56 is welded to the bottom of the inclined frame 55. The rice milling roller 57 is arranged on the side of the power shaft 52 away from the motor 51. The lower part of the rice milling roller 57 passes through the inclined frame 55. The rice milling roller 57 is located inside the rice milling cylinder 53. A plurality of fixed grinding strips 58 are welded to the outside of the rice milling roller 57. The rice milling roller 57 drives the fixed grinding strips 58 to rotate at a high speed to mill paddy rice.

[0033] The reciprocating screening mechanism 6 includes a sliding inclined frame 61, a movable hopper 62, a belt sleeve 63, a sieve 64, a fixed push plate 65 and a cam 66. The sliding inclined frame 61 is slidably connected to the lower part of the triangular support 1. The sliding inclined frame 61 is obliquely arranged and is used for guiding white rice. The power shaft 52 passes through the sliding inclined frame 61. The sliding inclined frame 61 is located below the inclined frame 55. The movable hopper 62 is rotatably connected to the middle of the power shaft 52. The upper end of the belt sleeve 63 is fixedly connected to the lower part of the movable hopper 62. The power shaft 52 passes through the belt sleeve 63. The lower end of the belt sleeve 63 is fixedly connected to the upper side of the sliding inclined frame 61. The movable hopper 62 and the belt sleeve 63 are used to prevent white rice from flowing out of the holes in the sliding inclined frame 61. The sieve 64 is fixedly connected to the sliding inclined frame 61 and is used for screening white rice to further separate white rice and bran powder. The sieve 64 is located above the bran powder collection frame 3. The fixed push plate 65 is welded to the bottom of the sliding inclined frame 61. The power shaft 52 passes through the fixed push plate 65. The cam 66 is arranged on one side of the power shaft 52 close to the motor 51. The cam 66 contacts the fixed push plate 65, and the rotation of the cam 66 will squeeze the fixed push plate 65 to move.

[0034] In actual operation, the staff adds the shelled paddy rice into the feeding cylinder 2, and the paddy rice will flow into the rice milling cylinder 53 from the feeding port of the feeding cylinder 2. Then the staff starts the motor 51. The high-speed rotation of the output shaft of the motor 51 will drive the power shaft 52 to rotate. The rotation of the power shaft 52 will drive the rice milling roller 57 to rotate. The rotation of the rice milling roller 57 will drive the fixed grinding strip 58 to rotate. The rotation of the fixed grinding strip 58 will polish the bran on the surface of the paddy rice in the rice milling cylinder 53. The polished bran powder will fly into the bran powder wrapping shell 54 from the holes in the rice milling cylinder 53 under the action of centrifugal force, and then fall from the bran powder wrapping shell 54 onto the inclined frame 55 and the soft aluminum plate 56. The bran powder falling on the inclined frame 55 and the soft aluminum plate 56 will flow along the inclined surface of the inclined frame 55 into the bran powder accumulation frame 4, thus polishing the bran on the surface of the paddy rice and separating the polished white rice and bran powder. The separated bran powder is collected in the bran powder accumulation frame 4.

[0035] At first, the staff put the bag storing white rice on the sliding inclined frame 61. The polished white rice will fall onto the sliding inclined frame 61 through the rice grinding cylinder 53. The white rice will flow along the inclined surface of the sliding inclined frame 61 to the sieve 64. While the power shaft 52 rotates, it will drive the cam 66 to rotate. The rotation of the cam 66 will intermittently squeeze the fixed push plate 65 to reciprocate. The reciprocating movement of the fixed push plate 65 will drive the sliding inclined frame 61 to reciprocate. The reciprocating movement of the sliding inclined frame 61 will drive the sieve 64 to reciprocate. The reciprocating movement of the sieve 64 will shake the polished white rice to shake off the bran powder remaining on the white rice. The shaken-off bran powder will fall into the bran powder collection box 3. The screened rice will flow onto the bag put on the sliding inclined frame 61, thus further screening the white rice and making the white rice and bran powder fully separated.

[0036] Embodiment 2

[0037] On the basis of Embodiment 1, as Figures 5 - 9 shown, it further includes a lifting scraping mechanism 7. The lifting scraping mechanism 7 is arranged on the sliding inclined frame 61 and connected to the triangular support 1. The lifting scraping mechanism 7 is used to scrape the bran powder remaining on the outer surface of the rice grinding cylinder 53, so that the holes of the rice grinding cylinder 53 are kept unobstructed, and further enables the rice grinding cylinder 53 to smoothly screen out the bran powder. The lifting scraping mechanism 7 includes a fixed convex plate 71, a lifting guide rod 72, a movable wheel 73, a transverse connecting rod 74, a closing sealing plate 75 and a lifting annular scraping rod 76. Two fixed convex plates 71 are welded on the upper part of the sliding inclined frame 61. The two fixed convex plates 71 are symmetrically arranged. Two lifting guide rods 72 are slidably connected to the upper part of the triangular support 1. The lifting guide rods 72 are vertically arranged. The two lifting guide rods 72 are symmetrically arranged. The movable wheel 73 is rotatably connected to the bottom end of the lifting guide rod 72. The movable wheel 73 contacts the fixed convex plate 71. The reciprocating movement of the fixed convex plate 71 will squeeze the movable wheel 73 to move up and down. The transverse connecting rod 74 is welded on the lower part of the lifting guide rod 72 on the side close to the bran powder wrapping shell 54. The transverse connecting rod 74 is slidably connected to the bran powder wrapping shell 54. A part of the transverse connecting rod 74 is located inside the bran powder wrapping shell 54. The closing sealing plate 75 is welded to the end of the transverse connecting rod 74 close to the bran powder wrapping shell 54. The closing sealing plate 75 contacts the outside of the bran powder wrapping shell 54. The closing sealing plate 75 is used to prevent the bran powder inside the bran powder wrapping shell 54 from splashing. A plurality of lifting annular scraping rods 76 are jointly welded on one side of the two transverse connecting rods 74 located inside the bran powder wrapping shell 54. The lifting annular scraping rods 76 contact the outside of the rice grinding cylinder 53. The up and down movement of the lifting annular scraping rods 76 will scrape the bran powder on the outside of the rice grinding cylinder 53.

[0038] The reciprocating movement of the sliding inclined frame 61 will drive the fixed convex plates 71 on both sides to reciprocate. The reciprocating movement of the fixed convex plates 71 will squeeze the movable wheels 73 to move up and down. At the same time, the reciprocating movement of the fixed convex plates 71 will drive the movable wheels 73 to rotate. The up and down movement of the movable wheels 73 will drive the lifting guide rod 72 to move up and down. The up and down movement of the lifting guide rod 72 will drive the horizontal connecting rod 74 to move up and down. The up and down movement of the horizontal connecting rod 74 will drive the closing sealing plate 75 and the lifting annular scraping rod 76 to move up and down. The up and down movement of the lifting annular scraping rod 76 will scrape off the bran powder remaining on the outer surface of the rice milling cylinder 53, keeping the holes of the rice milling cylinder 53 unobstructed, so that the rice milling cylinder 53 can smoothly screen out the bran powder.

[0039] Embodiment 3

[0040] On the basis of Embodiment 2, as Figure 9 shown, it further includes a flapping mechanism 8. The flapping mechanism 8 is arranged on the sliding inclined frame 61. The flapping mechanism 8 includes means for intermittently flapping the soft aluminum plate 56, so that the bran powder accumulated on the soft aluminum plate 56 shakes into the bran powder accumulation frame 4, avoiding the accumulation of bran powder on the soft aluminum plate 56. The flapping mechanism 8 includes a fixed wedge-shaped rod 81, a fixed seat 82, a pressing rod 83, a pressing spring 84, a horizontal flapping rod 85 and a fixed spherical block 86. Two fixed wedge-shaped rods 81 are welded to the top of the sliding inclined frame 61. The fixed wedge-shaped rods 81 are arranged vertically. The two fixed wedge-shaped rods 81 are symmetrically arranged. Fixed seats 82 are welded to both sides of the inclined frame 55. The two fixed seats 82 are symmetrically arranged. The pressing rod 83 is slidably connected to the fixed seat 82. The pressing rod 83 is arranged obliquely. A pressing spring 84 is connected between the fixed seat 82 and the pressing rod 83 by a hook. The lower ends of the two pressing rods 83 are jointly rotatably connected to a horizontal flapping rod 85. The horizontal flapping rod 85 is arranged horizontally. The horizontal flapping rod 85 contacts the fixed wedge-shaped rod 81. Four fixed spherical blocks 86 are fixedly connected to the horizontal flapping rod 85. When the fixed spherical block 86 moves upward, it will contact the soft aluminum plate 56, and the fixed spherical block 86 moving upward will flap the soft aluminum plate 56.

[0041] At first, due to the fixed wedge-shaped rods 81 on both sides squeezing the transverse flapping rod 85, the compression spring 84 is in a compressed state. When the sliding inclined frame 61 moves towards the direction close to the bran powder accumulation box 4, it will drive the fixed wedge-shaped rods 81 on both sides to move. When the fixed wedge-shaped rods 81 move, they will no longer squeeze the transverse flapping rod 85. The reset of the compression spring 84 will drive the extrusion rod 83 to move obliquely upwards. The two extrusion rods 83 moving obliquely upwards will drive the transverse flapping rod 85 to move obliquely upwards. The transverse flapping rod 85 moving obliquely upwards will drive the fixed ball block 86 to move obliquely upwards. When the fixed ball block 86 moves obliquely upwards, it will contact the bottom of the soft aluminum plate 56. The fixed ball block 86 will gently pat the soft aluminum plate 56. When the sliding inclined frame 61 moves away from the bran powder accumulation box 4, it will drive the fixed wedge-shaped rods 81 on both sides to reset. The reset of the fixed wedge-shaped rods 81 will squeeze the transverse flapping rod 85 to reset obliquely downwards. The transverse flapping rod 85 resetting obliquely downwards will drive the fixed ball block 86 and the extrusion rod 83 to reset obliquely downwards. The compression spring 84 is compressed. The fixed ball block 86 resetting obliquely downwards will be separated from the soft aluminum plate 56. Thus, the fixed ball block 86 intermittently pats the soft aluminum plate 56, causing the bran powder accumulated on the soft aluminum plate 56 to shake into the bran powder accumulation box 4, and preventing the bran powder from accumulating on the soft aluminum plate 56.

[0042] Embodiment 4

[0043] On the basis of Embodiment 3, as Figures 9 - 10 shown, it further includes a fixed special-shaped groove plate 91, an L-shaped pull rod 92 and a fixed scraping bar 93. On one side of the top of the sliding inclined frame 61 close to the fixed wedge-shaped rod 81, two fixed special-shaped groove plates 91 are fixedly connected. The fixed special-shaped groove plates 91 are arranged vertically. The two fixed special-shaped groove plates 91 are symmetrically arranged. Two L-shaped pull rods 92 are rotatably connected to the upper part of the inclined frame 55. The two L-shaped pull rods 92 are symmetrically arranged. One end of the L-shaped pull rod 92 is slidably connected to the fixed special-shaped groove plate 91. The movement of the fixed special-shaped groove plate 91 will drive the L-shaped pull rod 92 to move. The fixed scraping bar 93 is welded to the other end of the L-shaped pull rod 92. The movement of the L-shaped pull rod 92 will drive the fixed scraping bar 93 to move. The fixed scraping bar 93 is located above the soft aluminum plate 56. The fixed scraping bar 93 is used to scrape the bran powder located below the rice milling cylinder 53.

[0044] The reciprocating movement of the sliding inclined frame 61 will drive the fixed special-shaped groove plate 91 to reciprocate. The reciprocating movement of the fixed special-shaped groove plate 91 will drive the L-shaped pull rod 92 to reciprocate along the chute of the fixed special-shaped groove plate 91. The reciprocating movement of the L-shaped pull rod 92 will drive the fixed scraping bar 93 to reciprocate. The two fixed scraping bars 93 reciprocating will continuously scrape the bran powder accumulated below the rice milling cylinder 53 to both sides of the inclined frame 55, enabling the bran powder accumulated in the corners below the rice milling cylinder 53 to flow, and thus making the discharge of the bran powder more thorough.

[0045] Embodiment 5

[0046] Based on Embodiment 4, as Figure 11 shown, it further includes a steering rod 101 and a closing blade 102. The steering rod 101 is rotatably connected to the feeding cylinder 2. The steering rod 101 is vertically arranged. The closing blade 102 is welded to the lower part of the steering rod 101. The shape of the closing blade 102 is consistent with the material dropping port of the feeding cylinder 2. The closing blade 102 is located on the upper side of the bottom of the feeding cylinder 2. When the steering rod 101 rotates, it will drive the closing blade 102 to rotate, and when the closing blade 102 rotates, it will block the material dropping port of the cylinder 2.

[0047] When the staff pours paddy into the feeding cylinder 2, the flow of paddy can be controlled by rotating the steering rod 101. When the steering rod 101 rotates, it will drive the closing blade 102 to rotate, and when the closing blade 102 rotates, it will block the material dropping port at the bottom of the feeding cylinder 2. At this time, the paddy will no longer flow into the rice milling cylinder 53. When the staff rotates the steering rod 101 in the reverse direction, the reverse rotation of the steering rod 101 will drive the closing blade 102 to rotate in the reverse direction, and the reverse rotation of the closing blade 102 will no longer block the feeding cylinder 2.

[0048] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
