Description

Technical Field

[0001] This utility model relates to the field of rice processing equipment technology, and in particular to a swing-type broken rice sorting machine. Background Technology

[0002] In rice processing, the sorting of broken rice is a crucial step. Traditional sorting equipment separates broken rice by sieving it through a oscillating sieve. Referring to the existing authorized publication number CN 209577334U, "An Oscillating Broken Rice Sorting Machine," this machine uses grooves on the inner wall of the machine body to limit the oscillation range of the protrusions on the outer wall of the broken rice sorting chamber, replacing the traditional rubber spring limit function and thus extending the machine's lifespan. The baffle installed in the discharge area at the top of this oscillating broken rice sorting machine reduces the amount of rice falling, lowers the impact force on the sieve body, and extends the sieve's lifespan.

[0003] Careful research revealed that the aforementioned patents and existing technologies still have at least the following shortcomings: their functions are too limited, only capable of simple broken rice sorting operations. During the broken rice sorting process, impurities such as rice bran mixed in not only affect the screening efficiency but also cause dusting, affecting the working environment of the operators, resulting in low efficiency and unsatisfactory screening results.

[0004] To overcome these shortcomings, this utility model proposes a swing-type broken rice sorting machine.

[0031] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] Reference Figure 1-7A swing-type broken rice sorting machine includes a housing 1, a mounting box 5, a mounting frame 2, and multiple screen plates 22. A feed hopper 11 and a discharge cylinder 12 are fixedly installed on the top and bottom of the housing 1 on the side away from the mounting box 5, respectively. Multiple guide rods 21 arranged parallel to each other are fixedly installed on the inner walls of both sides of the housing 1. The mounting frame 2 is slidably mounted on the multiple guide rods 21. Multiple screen plates 22 are all fixedly installed at an incline on the inner side wall of the mounting frame 2. A U-shaped plate 42 is fixedly installed on one side of the mounting frame 2, and a reciprocating screw 41 is threaded onto the U-shaped plate 42. A motor 4 is fixedly installed on the side of the housing 1 away from the mounting box 5, and the output shaft of the motor 4 extends to... Inside the housing 1 and axially fixedly connected to the reciprocating screw 41, the mounting frame 2 can be controlled to swing back and forth along the guide rod 21. Multiple discharge cylinders 31 and multiple discharge cylinders 21 are fixedly installed on the side of the housing 1 and mounting frame 2 away from the discharge cylinder 12, respectively. The multiple discharge cylinders 21 extend into their corresponding discharge cylinders 31, allowing the material discharged from the screen plate 22 to be discharged without affecting the left-right swinging of the mounting frame 2. The mounting box 5 is located on the side of the housing 1 near the discharge assembly. A door is provided on the front of the mounting box 5, and the same connecting cylinder 51 is fixedly installed between the mounting box 5 and the housing 1. A [missing information - likely a device or component] is fixedly installed on the inner wall of the mounting box 5. A filter plate 52 is rotatably mounted inside a mounting box 5, with a fan blade 61 facing the rear of the mounting box 5. The rear end of a rotating shaft 6 is axially fixedly connected to the fan blade 61. A ratchet 62 is fixedly sleeved on the rotating shaft 6. A geared disc 63 is rotatably mounted on the rear side of the filter plate 52. A pawl 64 is hingedly mounted on the inner wall of the geared disc 63. A spring 65 is fixedly mounted on the inner wall of the geared disc 63. The end of the spring 65 away from the inner wall of the geared disc 63 is fixedly connected to the pawl 64. The pawl 64 is adapted to the ratchet 62. A toothed plate 66 is slidably mounted on the housing 1. One end of the toothed plate 66 is fixedly connected to the mounting frame 2. The end of the toothed plate 66 away from the mounting frame 2 extends into the mounting box 5 and meshes with the geared disc 63. The rotating shaft 6 can be controlled to rotate in one direction when the mounting frame 2 reciprocates left and right, thereby providing driving force for the fan blade 61. This allows the dust and rice bran raised during the material screening process in the housing 1 to be drawn into the mounting box 5 through the connecting cylinder 51 and intercepted by the filter plate 52. The front end of the rotating shaft 6 extends to the front side of the filter plate 52 and is radially fixedly mounted with an installation strip 67. Two cleaning brushes 68 are fixedly mounted on the side of the installation strip 67 near the filter plate 52. Both cleaning brushes 68 are in contact with the filter plate 52, enabling the filter plate 52 to self-clean when the rotating shaft 6 rotates, thereby effectively preventing the filter plate 52 from becoming clogged.

[0033] In this embodiment, in order to avoid contamination from rice bran and dust when the reciprocating screw 41 is located inside the mounting frame 2, a sleeve 43 with one end in a closed state is fixedly installed on the mounting frame 2, and the sleeve 43 is movably sleeved on the outside of the reciprocating screw 41.

[0034] In this embodiment, in order to provide stable support for the mounting box 5 and the multiple discharge cylinders 31, a support frame 32 is fixedly installed on the side of the box 1 away from the discharge cylinder 12, and the mounting box 5 and the multiple discharge cylinders 31 are all fixedly connected to the support frame 32.

[0035] In this embodiment, in order to improve the working stability of the rotating shaft 6, a support bar is fixedly installed inside the mounting box 5, and the rotating shaft 6 is rotatably connected to the support bar.

[0036] In this embodiment, in order to facilitate the flow of the material after being screened by the sieve plate 22 to the discharge cylinder 12, the bottom inner wall of the box body 1 is set with the left side higher than the right side.

[0037] In this embodiment, in order to facilitate the diversion of rice bran and other dust intercepted by the filter plate 52 to the front position inside the installation box 5, so that it can be easily removed after opening the box door, a guide plate is fixedly installed on the inner wall of the bottom of the installation box 5, and the guide plate is located on the front side of the filter plate 52.

[0038] Working principle: When in use, first connect the power supply and start the motor 4, then pour the broken rice to be sorted into the feed hopper 11. The motor 4 drives the reciprocating screw 41 to rotate, which can control the U-shaped plate 42 to drive the mounting frame 2 to swing back and forth. Since the screen plate 22 is fixedly installed on the inner side wall of the mounting frame 2 in an inclined shape, the material is screened on the screen plate 22. The finer broken rice falls through the screen holes and continues to be screened, while the coarser broken rice continues to be screened on the screen plate 22 and is discharged through the discharge cylinder 2 3 and the discharge cylinder 3 31 respectively.

[0039] As the mounting frame 2 swings back and forth, the toothed plate 66 controls the toothed disc 63 to rotate back and forth. With the cooperation of the pawl 64, spring 65 and ratchet 62, the rotating shaft 6 can be controlled to maintain unidirectional rotation, thereby providing a drive wheel for the fan blade 61. The rapid rotation of the fan blade 61 can draw the dust and rice bran raised during the material screening process in the box 1 into the mounting box 5 through the connecting cylinder 51. Under the action of the filter plate 52, the dust and rice bran are intercepted and filtered. The clean air is discharged from the rear of the mounting box 5 after passing through the filter plate 52. Since the rice bran and dust can be separated during the screening process, the screening efficiency can be improved to a certain extent.

[0040] When the rotating shaft 6 rotates, it can control the mounting strip 67 to drive the two cleaning brushes 68 to perform self-cleaning operation on the filter plate 52, thereby avoiding the filter plate 52 from being blocked and ensuring the stable operation of the device.

[0041] After screening is completed, open the door of the installation box 5 to easily remove the rice bran and other dust trapped on the guide plate, and also clean the accumulated dust inside the installation box 5.

[0042] The above provides a detailed description of the swing-type broken rice sorting machine provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
