Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, and in particular to a dual-spindle rice milling machine. Background Technology

[0002] A rice milling machine is a machine that mills and husks grains. With the development of agriculture and the increase in grain production, the demand for grain processing machines is also increasing. Among them, rice milling machines are being used more and more widely, which makes the demand for rice milling machines even higher.

[0003] However, most traditional equipment uses airflow screening. Although it can screen most impurities, traditional airflow screens mainly rely on the action of airflow to separate rice grains and impurities in a suspended state. For some impurities that are similar in weight and shape to rice grains, such as immature rice grains and small impurities with husks, it is difficult to accurately separate them by relying solely on the buoyancy and gravity of the airflow. As a result, some impurities may still remain in the screened rice grains, which seriously affects the processing quality of the equipment.

[0004] Therefore, it is necessary to provide a dual-spindle rice milling machine to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides a dual-shaft rice milling machine, which solves the problem that traditional devices using airflow sieves cannot effectively separate impurities, resulting in a significant reduction in processing quality.

[0006] To solve the above-mentioned technical problems, this utility model provides a dual-shaft rice milling machine comprising: a main body, the main body including a dual-shaft rice milling module, a dust extraction module, and a screening module; the screening module including a first driving component installed inside the main body, a rotating wheel provided on the output end of the first driving component, a horizontal shaft provided on the rotating wheel, a vertical connecting rod for connection provided on the horizontal shaft; a vertical guide groove provided on the main body, a screening guide block provided inside the vertical guide groove for guidance; a second sieve plate for screening the processed rice installed on the screening guide block; a device fixing block provided on the second sieve plate, a screening rotating shaft provided on the device fixing block; the screening module including a first sieve plate installed on the dual-shaft rice milling module; a small particle impurity collection box for collecting screened impurities provided below the first sieve plate; and a device door for convenient collection of bottom material provided on the main body.

[0007] Preferably, the vacuuming module includes a second driving component mounted on the dual-shaft rice milling module, and a reciprocating component for reciprocating motion is provided on the output end of the second driving component, and a cleaning brush is provided on the output end of the reciprocating component.

[0008] Preferably, the main body of the device is provided with a transverse sliding groove for guidance, and a sliding guide block is slidably connected inside the transverse sliding groove. The dust collection module is provided with an air intake filter, a vacuum cleaner is installed on the dust collection module, an air intake pipe is provided on the vacuum cleaner, and an air outlet is provided on the vacuum cleaner for exhaust.

[0009] Preferably, the dual-shaft rice milling module includes a drive box installed on the outer surface of the main body of the device, a rice milling component that can process rice is provided on the dual-shaft rice milling module, a discharge port is provided on the rice milling component, and a feed port is installed on the dual-shaft rice milling module.

[0010] Preferably, the device fixing block and the vertical connecting rod are rotatably connected by a screening shaft, and the screening guide block is slidably connected to the vertical guide groove.

[0011] Preferably, the sliding guide block is slidably connected to the transverse slide groove.

[0012] Preferably, the main body of the device is provided with an observation window for easy observation, and the main body of the device is equipped with a controller for controlling the operation of the device.

[0013] Compared with related technologies, the dual-spindle rice milling machine provided by this utility model has the following beneficial effects:

[0014] This invention provides a dual-shaft rice milling machine. Processed rice is discharged from the outlet and passes through a first screen plate for initial screening of small particles and impurities such as pebbles. Then, the operator controls a first drive unit to move a horizontal shaft, which in turn drives a second screen plate in a reciprocating motion for secondary screening. This device uses graded screening instead of traditional air-powered screening. It first removes larger impurities and then uses a fine screen to further screen out impurities and imperfect grains, enabling more comprehensive and precise separation of impurities in the rice. In contrast, this effectively avoids the situation where traditional air-powered screening relies mainly on wind and the suspension characteristics of particles, which may not effectively remove impurities similar in shape and weight to rice grains, thus improving processing quality.
