Technical Field

[0001] This utility model relates to the field of planar rotary cleaning screen technology, specifically an adjustable planar rotary cleaning screen for rice. Background Technology

[0002] A planar rotary screen is a commonly used screening device, widely used in chemical, pharmaceutical, and food industries. Its working principle is to separate solid particles according to their size by using the aperture size of the screen mesh.

[0003] For example, the utility model application with application number 202320097819.9 discloses a flat rotary cleaning screen for rice processing. The flat rotary cleaning screen similar to the above application still has the following shortcomings: although it is convenient to screen rice, it is not convenient to flexibly adjust the mesh density of the screen, and its applicability is not good.

[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed an adjustable rice planar rotary cleaning screen. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable rice planar rotary cleaning sieve to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable rice planar rotary cleaning sieve, comprising a base, a sieve box, and adjustable sieve components. The sieve box is located on the upper right side of the base, and two sets of adjustable sieve components are installed on the upper side of the sieve box. The adjustable sieve components include a mounting frame, a feed roller, a screen, a drive motor, and a cover plate. The mounting frame is located on the inner circumference of the sieve box, and feed rollers are rotatably installed in the grooves on both sides of the mounting frame. A screen is installed on the outer side of the feed rollers. A drive motor is installed at one end of the feed rollers, and the drive motor is located in the inner groove of the frame of the mounting frame. A cover plate is fixed on the upper side of the mounting frame, and the cover plate is inclined inward.

[0007] Furthermore, a support base is fixed on the upper left side of the base, and a drive mechanism is installed on the upper side of the support base.

[0008] Furthermore, a movable support frame is fixed at the bottom of the screening box, and the movable support frame is slidably connected to the base.

[0009] Furthermore, a first hopper is installed below the right side mounting frame of the upper set of adjustable screening components, and a second hopper is installed below the right side mounting frame of the lower set of components.

[0010] Furthermore, a third feeding hopper is installed on the lower right side of the screening box, and a material blocking component is installed on the left side of the third feeding hopper, the second feeding hopper, and the first feeding hopper.

[0011] Furthermore, the material blocking assembly includes a rotating shaft, a baffle, and a micro motor. The rotating shaft is rotatably connected to the inner wall of the mounting frame or the screen box, and a baffle is fixed to the lower side of the rotating shaft. A micro motor is installed at one end of the rotating shaft.

[0012] Furthermore, a guide plate is provided above the baffle and the rotating shaft, and the guide plate is fixedly connected to the inner wall of the mounting frame or the screen box, and the guide plate has an inclined structure.

[0013] Furthermore, the screen is provided with a feeding channel at the feed inlet of the first or second hopper, and a hollow support frame is provided on the lower side of the screen and is fixedly connected to the inner wall of the screen box.

[0014] This utility model provides an adjustable flat rotary rice cleaning sieve, which has the following beneficial effects:

[0015] This utility model is equipped with an adjustable screening component. The screen outside the take-up and untake-down rollers is composed of multiple flexible meshes of different densities. By unwinding the screen with one take-up and untake-down roller and winding it up with the other take-up and untake-down roller, screens of different densities can be adjusted, making it highly adaptable. The hollow support frame, which is fixedly connected to the inner wall of the screening box, can support the screen and prevent it from being deformed and damaged due to excessive pressure.

[0016] This utility model is equipped with a material blocking component. The drive mechanism facilitates the planar rotation of the screening box and its internal adjustable screening components, thereby causing the screening box to vibrate in the horizontal direction. This allows the rice to be evenly distributed on the upper and lower rows of screens and vibrate through the screen. The inclined guide plate guides the rice, and similarly, the baffle blocks the rice, preventing unscreened rice from being directly discharged through the second and third hoppers. The micro motor and rotating shaft facilitate the rotation of the baffle, allowing it to open during discharge for convenient and timely discharge. Attached Figure Description

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figures 1-3 As shown, an adjustable rice planar rotary cleaning sieve includes a base 1, a sieve box 4, and adjustable sieve components 6. The sieve box 4 is located on the upper right side of the base 1, and two sets of adjustable sieve components 6 are installed on the upper side of the interior of the sieve box 4. The adjustable sieve components 6 include a mounting frame 601, a take-up and release roller 602, a screen 603, a drive motor 604, and a cover plate 605. The mounting frame 601 is located on the inner circumference of the sieve box 4, and the take-up and release roller 602 is rotatably mounted in the grooves on both sides of the mounting frame 601. The screen 603 is located on the outer side of the take-up and release roller 602. The drive motor 604 is installed at one end of the take-up and release roller 602 and is located in the inner groove of the frame of the mounting frame 601. The cover plate 605 is fixed on the upper side of the mounting frame 601. Furthermore, the cover plate 605 is inclined inward, and the screen 603 has a discharge groove at the feed inlet of the first feed hopper 7 or the second feed hopper 8. The lower side of the screen 603 is provided with a hollow support frame 12 that is fixedly connected to the inner wall of the screen box 4. The screen 603 on the outside of the take-up and untake-down roller 602 is composed of multiple flexible meshes of different densities. By unwinding the screen 603 with the take-up and untake-down roller 602 on one side and winding the screen 603 with the take-up and untake-down roller 602 on the other side, the screen 603 of different densities can be adjusted, which has good applicability. Each screen 603 mesh has a discharge groove at the feed inlet of the first feed hopper 7 or the second feed hopper 8 to facilitate material discharge. The discharge groove of the screen 603 is not cut off, so it will not affect the winding and unwinding of the screen 603.

[0023] like Figures 1-2As shown, a support base 2 is fixed on the upper left side of the base 1, and a drive mechanism 3 is installed on the upper side of the support base 2. A movable support frame 5 is fixed at the bottom of the screening box 4, and the movable support frame 5 is slidably connected to the base 1. A first hopper 7 is installed below the right side mounting frame 601 of the upper set of adjustable screening components 6, a second hopper 8 is installed below the right side mounting frame 601 of the lower set, and a third hopper 9 is installed on the lower right side of the screening box 4. A baffle assembly 10 is installed on the left side of the third hopper 9, the second hopper 8, and the first hopper 7. The drive mechanism... 3. This facilitates the planar rotation of the screening box 4 and its internal adjustable screening component 6, thereby causing the screening box 4 to vibrate in the horizontal direction. This allows the rice to be evenly distributed and vibrated through the upper and lower rows of screens 603. The upper adjustable screening component 6 can screen the rice once, and the unscreened rice is fed through the first hopper 7. The lower adjustable screening component 6 can screen the rice a second time, and the unscreened rice is fed through the second hopper 8. The rice after the second screening is fed through the third hopper 9, thus achieving the purpose of separation.

[0024] like Figure 1 and Figure 3 As shown, the baffle assembly 10 includes a rotating shaft 1001, a baffle 1002, and a micro motor 1003. The rotating shaft 1001 is rotatably connected to the inner wall of the mounting frame 601 or the screen box 4, and the baffle 1002 is fixed to the lower side of the rotating shaft 1001. The micro motor 1003 is installed at one end of the rotating shaft 1001. A guide plate 11 is provided above the baffle 1002 and the rotating shaft 1001, and the guide plate 11 is fixedly connected to the inner wall of the mounting frame 601 or the screen box 4. The guide plate 11 has an inclined structure. The inner wall of the box 4 is a fixedly connected hollow support frame 12 that can support the screen 603 and prevent the screen 603 from being deformed and damaged due to excessive pressure. The inclined guide plate 11 can guide the rice. Similarly, the baffle 1002 can block the rice and prevent unscreened rice from being directly fed into the second feed hopper 8 and the third feed hopper 9. The micro motor 1003 and the rotating shaft 1001 can easily drive the rotation of the baffle 1002, so that the baffle 1002 can be rotated and opened during feeding for convenient and timely feeding.

[0025] In summary, as Figures 1-3As shown, this adjustable rice planar rotary cleaning sieve first pours rice onto the upper sieve 603. The sieve 603 outside the take-up and untake-down roller 602 is composed of multiple flexible meshes of different densities. The hollow support frame 12, which is fixedly connected to the inner wall of the sieve box 4, can support the sieve 603 and prevent it from being deformed and damaged due to excessive pressure. The take-up and untake-down roller 602 on one side rotates to unwind the sieve 603, and the take-up and untake-down roller 602 on the other side rotates to wind the sieve 603, thus adjusting the density of the sieve 603. Then, the drive mechanism 3 drives the planar rotary motion of the sieve box 4 and its internal adjustable sieve assembly 6, thereby causing the sieve box 4 to vibrate in the horizontal direction. This causes the rice to be evenly distributed on the upper and lower rows of sieves 603 and vibrate through the sieve. Each sieve 603 mesh corresponds to the first feed hopper 7 or the second feed hopper 8. The feed inlet is equipped with a discharge chute for easy feeding. The adjustable screening assembly 6 on the upper side can screen the rice once. Unscreened rice is fed through the first discharge hopper 7. The adjustable screening assembly 6 on the lower side can screen the rice a second time. Unscreened rice is fed through the second discharge hopper 8. The rice after the second screening is fed through the third discharge hopper 9, thus achieving the purpose of separation. In this process, the inclined guide plate 11 can guide the rice. Similarly, the baffle 1002 can block the rice, preventing unscreened rice from being directly fed through the second discharge hopper 8 and the third discharge hopper 9. When feeding, the micro motor 1003 and the rotating shaft 1001 can drive the baffle 1002 to rotate and open, so that the baffle 1002 can be rotated to open for timely feeding. This completes the use process of the adjustable rice planar rotary cleaning screen.
