[0027] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0028] like Figure 1 - Figure 4 As shown, this utility model provides a technical solution:

[0029] A rice polishing machine with a sieving function includes:

[0030] The base 1 has two upright plates 2 and a partition plate 3 fixedly connected to it. One side of one of the upright plates 2 is fixedly connected to a motor 7 and a fixing frame 4. A polishing chamber 5 is fixedly connected between the two upright plates 2. A feed port 6 is provided on the polishing chamber 5. The output end of the motor 7 is coaxially fixedly connected to a No. 1 pulley 13 and a polishing roller 9. One end of the polishing roller 9 is coaxially fixedly connected to a spiral propeller 8.

[0031] A rotating shaft 14 is rotatably connected to the side wall of the fixed frame 4. The rotating shaft 14 passes through the fixed frame 4 and is coaxially fixed to two ends of a second pulley 15 and a first bevel gear 16, respectively. A belt is sleeved between the second pulley 15 and the first pulley 13. A crankshaft 17 is rotatably connected inside the fixed frame 4. A second bevel gear 23 is coaxially fixed to the crankshaft 17. A connecting rod 18 is rotatably connected to the crankshaft 17. The first bevel gear 16 and the second bevel gear 23 mesh with each other.

[0032] Specifically, when the motor 7 is started, it drives the polishing roller 9 and the first pulley 13 to rotate. At the same time, it drives the screw propeller 8, which is coaxially fixedly connected to the polishing roller 9. The first pulley 13 then drives the second pulley 15 to rotate via the belt, thereby driving the rotating shaft 14 to rotate, which in turn drives the first bevel gear 16 to rotate. Since the first bevel gear 16 and the second bevel gear 23 mesh with each other, and the second bevel gear 23 is coaxially fixedly connected to the crankshaft 17, the rotating shaft 14 will drive the crankshaft 17 to rotate.

[0033] A screening box 10 and a collection box 21 are provided between one of the upright plates 2 and the partition plate 3. A pull rod 22 is fixedly connected to one side of the screening box 10. The pull rod 22 is rotatably connected to one end of the connecting rod 18. Two sliding rods 19 are fixedly connected to the other side of the screening box 10.

[0034] The slide rod 19 passes through the partition 3 and is slidably connected to it. One end of the two slide rods 19 is fixedly connected to the first limiting plate 12. A spring 24 is sleeved on the outer wall of the slide rod 19. The two ends of the spring 24 abut against the first limiting plate 12 and the partition 3 respectively.

[0035] Specifically, one end of the connecting rod 17 pulls the pull rod 22, which in turn pulls the screening box 10. The screening box 10 completes the horizontal reciprocating motion through the pull rod 22 and two sliding rods 19. The reciprocating motion of the screening box 10 increases the flowability of rice in the screening box 10, which can improve the screening efficiency of the sieve plate 11. The spring 24 can buffer the screening box 10 and reduce the risk of the device jamming.

[0036] The bottom of the screening box 10 has a groove, and a screen plate 11 is slidably connected in the groove. A second limiting plate 20 is fixedly connected to one side of the screen plate 11, and a handle is fixedly connected to the second limiting plate 20.

[0037] Polishing discs are laid on the inner wall of polishing chamber 5, and multiple scrapers are provided on polishing roller 9;

[0038] The collection box 21 is positioned directly below the screening box 10;

[0039] Specifically, the rice is first pushed by the spiral propeller 8 to the polishing drum 9 after entering the polishing bin 5, and then is scraped by the scraper on the polishing drum 9 and rubbed with the polishing sheet on the inner wall of the polishing bin 5, and the polished rice enters the screening box 10, and the broken rice and dust generated during polishing of the rice fall into the collecting box 21 through the sieve plate 11, and the sieve plate 11 can be fixed at the bottom of the screening box 10 by tightening the screws on both sides of the second limiting plate 20.

[0040] The working principle of the utility model is as follows:

[0041] The motor 7 drives the polishing drum 9 and the first belt pulley 13 to rotate, and simultaneously drives the spiral propeller 8 fixedly connected coaxially with the polishing drum 9, and the first belt pulley 13 drives the second belt pulley 15 to rotate through the belt, thereby driving the rotating shaft 14 to rotate, and further driving the bevel gear 16 to rotate, since the first bevel gear 16 and the second bevel gear 23 are engaged with each other, and the second bevel gear 23 is fixedly connected coaxially with the crankshaft 17, so the rotating shaft 14 drives the crankshaft 17 to rotate, thereby driving one end of the connecting rod 17 to make circular motion, and the other end of the connecting rod 17 drives the screening box 10 to move through the pull rod 22, thereby enabling the screening box 10 to complete the reciprocating motion in the horizontal direction.

[0042] At this time, the rice to be polished is poured from the feeding hopper 6, and the rice enters the polishing bin 5 and is pushed by the spiral propeller 8 to the polishing drum 9, and the polished rice falls into the screening box 10 from the discharge port, and the broken rice and dust generated during polishing of the rice fall into the collecting box 21 through the sieve plate 11, and the reciprocating motion of the screening box 10 increases the flowability of the rice in the screening box 10, thereby improving the screening efficiency of the sieve plate 11.

[0043] After the polishing of the rice is completed, the motor 7 is turned off, the collecting box 21 is removed, and the materials in the collecting box 21 are taken out, then the collecting box 21 is put back to the original position, the screws for fixing the second limiting plate 20 are unscrewed, the second limiting plate 20 is pulled out through the handle, thereby taking out the sieve plate 11, at this time, the complete rice screened is fallen into the collecting box 21, and the collection of the complete rice is completed, and the taken-out sieve plate 11 can be cleaned or replaced.

[0044] The preferred embodiments of the utility model are described in detail above, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by those skilled in the art without departing from the purpose of the utility model.
