[0050] Please see Figures 1-5 The present invention provides the following technical solution: a cleaning sieve for rice production, including a working box 1, and further including: a movable seat 2, a square sieve cylinder 3, a perforated sieve plate 4, a drive mechanism 5, and an impurity recovery drawer 6.

[0051] Furthermore, by Figure 1 and Figure 2As shown, in this embodiment, two movable seats 2 are symmetrically distributed and horizontally movably connected to both sides of the working box 1. A square screen cylinder 3 is fixed to the top of the movable seat 2, and a feeding hopper 31 is fixed to the top of the square screen cylinder 3. A discharge port 32 is machined on the outer side of the square screen cylinder 3, and a discharge slide plate 33 located at the bottom of the discharge port 32 is fixed on the outer side of the square screen cylinder 3. A perforated screen plate 4 is inclined and installed in the square screen cylinder 3 by a pull-out method. The square screen cylinder 3 has a disassembly and assembly port 35 through which the perforated screen plate 4 passes. A drive mechanism 5 is drivably connected to the square screen cylinder 3 and is used to drive the square screen cylinder 3 to reciprocate in the horizontal direction. An impurity recovery drawer 6 is installed in the working box 1 by a pull-out method and is located below the square screen cylinder 3. After implementing the above scheme, during use, the drive mechanism 5 is activated to drive the square screen cylinder 3 to move back and forth in the horizontal direction, causing the perforated screen plate 4 to vibrate laterally. Then, the rice to be screened is put into the feeding hopper 31. Under its own gravity, the rice enters the square screen cylinder 3 and passes through the perforated screen plate 4 to remove rice bran. The rice bran passes through the mesh of the perforated screen plate 4 and enters the impurity collection drawer 6, while the rice is fed down along the inclined surface of the perforated screen plate 4 and finally discharged from the discharge port 32. The perforated screen plate 4 of this utility model is set at an inclination and is installed in the square screen cylinder 3 by a pull-out method, which facilitates the discharge after screening and also makes it easy to replace the perforated screen plate 4 with different apertures according to the actual screening needs. The screened impurities are collected in the impurity collection drawer 6 for convenient centralized processing.

[0052] Optionally, by Figure 1 and Figure 3 As shown, in this embodiment, the drive mechanism 5 includes: a connecting beam 51, a motor frame 52, a turntable 53, a connecting arm 55, and a drive motor 56. The connecting beam 51 is fixedly connected to one end of the movable seat 2. The motor frame 52 is fixed to the end of the working box 1. The turntable 53 is rotatably connected to the motor frame 52, and a drive rod 54 is fixed at an eccentric position on the top surface of the turntable 53. One end of the connecting arm 55 is hinged to the connecting beam 51, and the drive rod 54 passes through the other end of the connecting arm 55 to form a rotating structure. The drive motor 56 is fixed on the motor frame 52 and is used to drive the turntable 53 to rotate. With the above scheme, when in use, the drive motor 56 is started to drive the turntable 53 to rotate. The turntable 53 drives the drive rod 54 to make a circular motion, and drives the connecting arm 55 to move and swing. The connecting arm 55 drives the square screen cylinder 3 to move back and forth in the horizontal direction, so that the porous screen plate 4 generates lateral vibration.

[0053] Preferably, by Figure 1 , Figure 3 and Figure 5As shown, this embodiment also includes: a fixing ear 10, a guide rod 11, and a balance spring 12. The two fixing ears 10 are symmetrically fixed to the outer wall of the working box 1. The guide rod 11 is fixed between the two fixing ears 10 and passes through the movable seat 2. Balance springs 12 are distributed at both ends of the movable seat 2 and are sleeved on the guide rod 11. With the above solution, when the square screen cylinder 3 moves, it will drive the movable seat 2 to move along the guide rod 11. The balance spring 12 contracts and has a reverse elastic force. The balance springs 12 on both sides cooperate to improve the stability of the square screen cylinder 3.

[0054] Preferably, by Figure 1 and Figure 3 As shown, this embodiment also includes: a limiting plate 41 and a locking bolt 9. The limiting plate 41 is fixed to one end of the porous screen plate 4. A threaded hole 36 is machined on the square screen cylinder 3. The locking bolt 9 passes through the limiting plate 41 and is screwed into the threaded hole 36 by thread engagement. With the above scheme, when the porous screen plate 4 is completely pushed into the square screen cylinder 3, the locking bolt 9 is tightened to ensure the stability of the porous screen plate 4.

[0055] Preferably, by Figure 1 As shown, in this embodiment, it also includes a support bar 34, which is fixed to the inner wall of the square screen cylinder 3 to support the porous screen plate 4 and further improve the stability of the porous screen plate 4.

[0056] Preferably, by Figure 1 and Figure 4 As shown, this embodiment also includes a limiting mechanism 8. After the impurity recovery drawer 6 is fully pushed into the working box 1, it is limited by the limiting mechanism 8. The limiting mechanism 8 includes: an L-shaped limiting block 81, a mounting rod 82, a limiting plate 83, a return spring 84, and a pull ring 85. The mounting rod 82 is fixed to the outer wall of the working box 1 and passes through the L-shaped limiting block 81. The limiting plate 83 is fixed to the end of the mounting rod 82 away from the working box 1. The return spring 84 is sleeved on the mounting rod 82 and is located between the L-shaped limiting block 81 and the working box 1. Between the limiting plates 83, the pull ring 85 is fixed to the outer wall of the L-shaped limiting block 81. After the above scheme is adopted, after the impurity recovery drawer 6 is completely pushed into the working box 1, the L-shaped limiting block 81 is pulled outward by the pull ring 85 and rotated at a certain angle so that one end of the L-shaped limiting block 81 is parallel to the end face of the impurity recovery drawer 6. At this time, the pull ring 85 is released and the return spring 84 releases its elastic force to reset the L-shaped limiting block 81. The impurity recovery drawer 6 is limited from the end by the L-shaped limiting block 81.

[0057] Preferably, by Figure 1 As shown, this embodiment also includes a handle 61, which is fixed to one end of the impurity recovery drawer 6. With the above solution, the impurity recovery drawer 6 can be easily moved by the handle 61 during use.

[0058] Preferably, by Figure 1 As shown, this embodiment also includes: four locking casters 7, which are fixed diagonally to the four corners of the bottom surface of the work box 1. With the above solution, the cleaning screen can be moved easily by the four locking casters 7 during use, making it convenient to use in different environments.

[0059] It should be noted that the drive motor 56 is a commercially available standard device with a built-in power switch. Those skilled in the art can make conventional selections according to their needs. Its working principle is common knowledge known to those skilled in the art and has been fully disclosed in the prior art, so it will not be elaborated further in this article.

[0060] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0061] Components not described in detail in this article are existing technologies.

[0062] The working principle and usage process of this utility model: When using the cleaning screen of this utility model, the drive motor 56 is started to drive the turntable 53 to rotate. The turntable 53 drives the drive rod 54 to make a circular motion, and drives the connecting arm 55 to move and swing. Through the connecting arm 55, the square screen cylinder 3 is driven to move back and forth in the horizontal direction, so that the porous screen plate 4 generates lateral vibration.

[0063] Then, the rice to be screened is put into the feeding hopper 31. Under its own gravity, the rice enters the square screen cylinder 3 and the rice bran mixed in the rice is removed by the perforated screen plate 4. The rice bran passes through the mesh of the perforated screen plate 4 and enters the impurity recovery drawer 6, while the rice will be fed down along the slope of the perforated screen plate 4 and finally discharged from the discharge port 32.

[0064] The perforated sieve plate 4 of this utility model is set at an angle and installed in the square sieve cylinder 3 by a pull-out method, which facilitates the discharge of the material after screening and also makes it easy to replace the perforated sieve plate 4 with different apertures according to the actual screening needs. The screened impurities are collected in the impurity recovery drawer 6 for convenient centralized processing.

[0065] When it is necessary to replace the perforated sieve plate 4, simply unscrew the locking bolt 9 and pull out the perforated sieve plate 4 directly, which is easy to operate.

[0066] When cleaning the impurity recovery drawer 6, use the pull ring 85 to pull out the L-shaped limit block 81. After the L-shaped limit block 81 is separated from the work box 1, rotate the L-shaped limit block 81 at a certain angle so that the L-shaped limit block 81 is offset from the impurity recovery drawer 6, and then the impurity recovery drawer 6 can be pulled out. The operation is convenient.
