Description

Technical Field

[0001] The utility model relates to the technical field of rice screening, in particular to a rice processing screening machine. Background Art

[0002] As a key equipment in the field of grain processing, the core responsibility of rice screening machine is to accurately screen and clean rice to remove impurities, thereby ensuring the purity and overall quality of rice. However, in actual application, although the rice screening machine adopts a multi-layer screening design and effectively separates rice from impurities through sieve holes of different diameters, there are still some defects and challenges that cannot be ignored.

[0003] First of all, from the perspective of discharging, the multi-layer screening design of the rice screening machine improves the screening accuracy, but it also makes the discharging process relatively cumbersome. The materials on each layer of the screen need to be handled separately, which undoubtedly increases the complexity and difficulty of the operation, and may also lead to a decrease in the overall screening efficiency.

[0004] Secondly, rice grains getting stuck in the sieve holes is a common and annoying problem. This is mainly due to the combined influence of multiple factors such as the shape, size and humidity of the rice grains. In some cases, some rice grains may get stuck in the sieve holes due to irregular shapes or high humidity, which will not only reduce the screening efficiency, but may also cause damage to the screen, further affecting the service life and performance of the sieving machine.

[0005] Therefore, in response to the above problems, it is necessary for us to further optimize and improve the rice screening machine to improve its screening efficiency and ease of operation and ensure the smooth progress of the rice processing process. Utility Model Content

[0006] The main purpose of the utility model is to provide a rice processing screening machine, which can effectively solve the problems raised in the background technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A rice processing and screening machine comprises a support frame, a transmission device, a reducer, a driving motor, a feed port and a rotating drum, wherein two transmission devices are arranged at the upper end of the support frame, a first rotating drum and a second rotating drum are mounted on the two transmission devices, and one of the transmission devices is connected to the driving motor via a reducer;

[0009] An outer screening cylinder is provided between the first rotating cylinder and the second rotating cylinder, and the outer screening cylinder is driven to rotate by a power assembly to achieve material screening in the outer screening cylinder;

[0010] The first rotating cylinder and the second rotating cylinder are connected to a connecting cylinder through a connecting piece, and an inner screening cylinder is arranged between the two connecting cylinders. The material is screened by the inner screening cylinder, and a jumping ring is arranged on the inner screening cylinder. Screening holes are opened on the surfaces of the inner screening cylinder and the jumping ring, which drive the material to jump and then pass through the screening holes for screening.

[0011] As a further preferred embodiment of the present invention, the driving motor, the reducer and the transmission device are fixed to the support frame by bolts, and the annular transmission device is fixed to the first rotating cylinder or the second rotating cylinder by bolts;

[0012] As a further preferred embodiment of the present invention, the outer screening cylinder is fixed to the first rotating cylinder and the second rotating cylinder by bolts, and a sealing ring is provided at the connection between the outer screening cylinder and the first rotating cylinder and the second rotating cylinder;

[0013] As a further preferred embodiment of the present invention, the connecting cylinder is welded and fixed to the inner screening cylinder, and the inner screening cylinder is integrally designed with the jump ring, and the cross-sections of the jump ring and the inner screening cylinder are wavy in design;

[0014] As a further preferred embodiment of the present invention, the side wall of the connecting cylinder is provided with a plurality of circular holes, the circular holes on the first rotating cylinder and the second rotating cylinder are directly opposite to the circular holes on the connecting cylinder, the connecting members are bolts, nuts and anti-slip washers, the bolts pass through the two circular holes and are sleeved with nuts and anti-slip washers to achieve the fixing of the three;

[0015] As a further preferred embodiment of the present invention, the outlets of the second rotating cylinder and the connecting cylinder are discharge ports, and the outer screening cylinder and the inner screening cylinder realize multi-layer screening.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] In the utility model, the multi-layer screening structure adopted by the rice screening machine includes an outer screening cylinder and an inner screening cylinder, which realizes the preliminary screening and further detailed screening of the material. This multi-layer design ensures that the material can be effectively processed when passing through each layer of screening, greatly improving the overall screening efficiency. The multi-layer screening structure can remove impurities and rice particles that do not meet the requirements in the material layer by layer, ensuring the purity and quality of the rice after screening. The coordinated use of the outer screening cylinder and the inner screening cylinder makes the screening effect more accurate and meets the needs of different users for rice quality. The multi-layer screening structure has high design flexibility, and the number of screening layers and the size of the sieve holes can be adjusted according to actual production needs. This design enables the rice screening machine to adapt to the screening needs of rice of different types and qualities, and improves the versatility and adaptability of the equipment.

[0018] The jump ring set on the surface of the inner screening cylinder can cause the material to jump during the screening process. This jumping action helps the material to form a more even distribution around the screening hole, thereby improving the uniformity and efficiency of the screening. The design of the jump ring helps prevent the material from clogging at the screening hole. When the material passes through the screening hole during the jumping process, the impact force generated by the jump ring can effectively clear the material clogging on the screen hole, ensuring the smooth progress of the screening process. Through the design of the jump ring, the material can pass through the screening hole faster during the screening process, thereby reducing the residence time of the material in the screening machine. This not only improves the screening efficiency, but also reduces the energy consumption and operating costs of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 - Figure 4 As shown, a high-efficiency multi-layer screening rice processing equipment mainly includes a support frame 1, a transmission device 2, a reducer 3, a drive motor 4, a feed port 5, and key working parts - a rotating cylinder and an outer screening cylinder 8, and an inner screening cylinder 11.

[0026] At the solid upper end of the support frame 1, two transmission devices 2 are firmly mounted, each of which carries the first rotating drum 6 and the second rotating drum 7. In particular, one of the transmission devices 2 is closely connected to the driving motor 4 through the reducer 3 to ensure stable operation and precise control of the rotating drum.

[0027] In order to achieve a multi-level screening effect, we cleverly set an outer screening drum 8 between the first rotating drum 6 and the second rotating drum 7. Through the carefully designed power assembly, the outer screening drum 8 can rotate efficiently, thereby achieving preliminary screening of the material.

[0028] In order to further enhance the screening effect, we also connect two connecting cylinders 9 between the two rotating cylinders through connecting parts 10 (specifically bolts, nuts and anti-slip gaskets), and install an inner screening cylinder 11 between the two connecting cylinders 9. This design allows the material to be further screened more finely through the inner screening cylinder 11 after being preliminarily screened by the outer screening cylinder 8.

[0029] The design of the inner screening cylinder 11 is particularly unique, with a jump ring 12 on its surface, the two being designed as one body, and both having a wavy cross section. This design can effectively drive the material to jump, making the material smoother when passing through the screening hole 13, thereby achieving efficient screening.

[0030] In order to ensure the stability and sealing of the equipment, the driving motor 4, the reducer 3 and the transmission device 2 are tightly fixed on the support frame 1 by bolts. At the same time, sealing rings are provided at the connection between the outer screening drum 8 and the first rotating drum 6 and the second rotating drum 7 to prevent material leakage.

[0031] The connecting cylinder 9 and the inner screening cylinder 11 are fixed by welding to ensure the stability of the structure. At the same time, the side wall of the connecting cylinder 9 is provided with a plurality of circular holes, which correspond to the circular holes on the first rotating cylinder 6 and the second rotating cylinder 7, and are fixed by bolts, nuts and anti-slip gaskets.

[0032] Finally, the multi-layer screened material is discharged from the outlet (i.e., the discharge port) of the second rotating cylinder 7 and the connecting cylinder 9, completing the entire screening process. This highly efficient multi-layer screening rice processing equipment not only improves the screening efficiency, but also ensures the accuracy of the screening effect, bringing significant benefits to the rice processing industry.

[0033] Screening process:

[0034] The driving motor 4 is started, and transmits power to the transmission device 2 through the reducer 3. The transmission device 2 drives the first rotating drum 6 and the second rotating drum 7 to start rotating.

[0035] When the rice enters the device from the feed port 5, it first falls into the outer screening drum 8. The outer screening drum 8 rotates with the rotation of the first rotating drum 6 and the second rotating drum 7 to perform preliminary screening on the rice.

[0036] The rice after preliminary screening enters the inner layer through the gap between the outer screening cylinder 8 and the rotating cylinder. Under the guidance of the two connecting cylinders 9, the rice enters the inner screening cylinder 11.

[0037] The inner screening cylinder 11 rotates with the rotation of the connecting cylinder 9, and the jumping ring 12 on its surface helps the rice to jump during the screening process. When the jumping rice passes through the screening hole 13, finer particles fall through the screening hole 13, achieving fine screening.

[0038] After the screening is completed, the screened rice is discharged from the outlet (i.e., the discharge port) of the second rotating drum 7 and the connecting drum 9. Rice of different particle sizes is collected into different collection containers, completing the entire screening process.

[0039] During the whole screening process, the various parts of the equipment are fastened by bolts, nuts and anti-skid pads to ensure the stability of the equipment operation. A sealing ring is provided at the connection between the outer screening cylinder 8 and the rotating cylinder to effectively prevent material leakage.

[0040] Through this high-efficiency multi-layer screening rice processing equipment, rice can undergo multi-level screening, ensuring the screening efficiency and accuracy of the screening effect, bringing significant benefits to the rice processing industry.
