[0004] In existing rice milling machines, after the material is fed in, it needs to be screened by a sieve and then subjected to gravity removal of sand and gravel by a grain destoner before being transported to a rice huller for dehulling. The overall impurity removal process is quite complex and complicated, which reduces the efficiency of feeding the material into the rice huller. Therefore, we need to propose a combined rice milling machine. Utility Model Content

This reduces the processing steps required for the material to enter the rice huller for hulling, improves the efficiency of impurity removal, and thus increases the material processing efficiency, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a combined rice milling machine, comprising:

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a combined rice milling machine, comprising:

[0025] The support 10 and the material screening structure 20 installed on the support 10 are provided. The material screening structure 20 is equipped with a material lifting mechanism 30 for conveying materials. The material lifting mechanism 30 enables the material to move inside the material screening structure 20. The material screening structure 20 is used to remove impurities from the material during the conveying process.

[0026] The material screening structure 20 includes a first guide cylinder 201, a transfer channel 205, and a second guide cylinder 207. The transfer channel 205 is located at the upper end of the outer side of the first guide cylinder 201, and the discharge end of the transfer channel 205 is located at the lower end of the outer side of the second guide cylinder 207. Multiple sets of first screen holes 204 are opened in the middle of the outer side of the first guide cylinder 201, and multiple sets of second screen holes 206 are opened on the lower surface of the transfer channel 205. The diameter of the first screen holes 204 is larger than the diameter of the second screen holes 206, and the diameters of both the first screen holes 204 and the second screen holes 206 are smaller than the diameter of the grain, so as to remove small particle impurities in the grain.

[0027] The material lifting mechanism 30 includes a first conveying component, a second conveying component, and an anti-blocking component. The first conveying component is installed inside the second guide cylinder 207, the second conveying component is located inside the first guide cylinder 201, and the anti-blocking component is located at the feed end of the first guide cylinder 201. A first synchronous belt 305 is provided between the first conveying component and the second conveying component, and a second synchronous belt 3010 is provided between the second conveying component and the anti-blocking component.

[0028] Specifically, the first conveyor can drive the second conveyor to operate synchronously through the first synchronous belt 305. At the same time, the second synchronous belt 3010 drives the anti-blocking component to operate synchronously, thereby facilitating the feeding of grain to avoid layering and ensuring the stability of grain conveying. During the conveying process, impurities can be screened out through the first screen hole 204 and the second screen hole 206. The first guide cylinder 201 and the second guide cylinder 207 are both inclined to facilitate the falling out of impurities through the first screen hole 204 and the second screen hole 206.

[0029] The first conveying component includes a first rotating shaft 302 rotatably disposed in the inner cavity of the second guide cylinder 207. The lower end of the first rotating shaft 302 passes through the second guide cylinder 207 and is driven by a drive motor 301. A first spiral blade 303 is disposed on the outer side of the first rotating shaft 302. The upper end of the first rotating shaft 302 passes through the second guide cylinder 207 and is provided with a first synchronous pulley 304 for mounting the first synchronous belt 305.

[0030] In this embodiment, the first rotating shaft 302 inside the second guide cylinder 207 is driven to rotate by the drive motor 301, thereby enabling the first rotating shaft 302 to drive the first spiral blades 303 to convey the screened grains. The grains are then conveyed into the huller through the discharge channel 208, improving the efficiency of material conveying.

[0031] The second conveying component includes a second rotating shaft 307 rotatably disposed in the inner cavity of the first guide cylinder 201. The upper end of the second rotating shaft 307 passes through the first guide cylinder 201 and is provided with a second synchronous pulley 306 for mounting the first synchronous belt 305. A second spiral blade 308 is provided on the outer side of the second rotating shaft 307. The lower end of the second rotating shaft 307 passes through the first guide cylinder 201 and is provided with a third synchronous pulley 309 for mounting the second synchronous belt 3010.

[0032] In a further preferred embodiment, the second synchronous pulley 306 is driven to rotate by the first synchronous belt 305, which in turn drives the second rotating shaft 307 to rotate. The grain in the feed hopper 203 is conveyed upward by the second spiral blade 308, and passes through the first screen hole 204 during the conveying process, through which large particles of impurities and sand are screened out.

[0033] The lower outer end of the first guide cylinder 201 is provided with a feed hopper 203, and the lower outer end of the first guide cylinder 201 is provided with a feed hole 202 that communicates with the first guide cylinder 201. The upper outer end of the second guide cylinder 207 is provided with a discharge channel 208.

[0034] Preferably, a large amount of grain is pre-stored in the feed hopper 203, and the grain enters the first guide cylinder 201 through the feed hole 202, which facilitates the second conveyor to lift the grain upward, so that it passes through the transfer channel 205 and the second guide cylinder 207 in sequence and is then fed into the rice huller through the discharge channel 208.

[0035] The anti-clogging component includes a third rotating shaft 3012 rotatably disposed at the bottom of the feed hopper 203. The lower end of the third rotating shaft 3012 passes through the feed hopper 203 and is provided with a fourth synchronous pulley 3011 for mounting the second synchronous belt 3010. The upper end of the third rotating shaft 3012 is provided with multiple sets of stirring rods 3013.

[0036] Furthermore, the third synchronous pulley 309 drives the second synchronous belt 3010 on the fourth synchronous pulley 3011, thereby driving the third rotating shaft 3012. The stirring rod 3013 on the third rotating shaft 3012 agitates the grain at the feed hole 202, preventing grain accumulation, facilitating grain entry, and improving practicality. The outer sides of the first synchronous pulley 304, the second synchronous pulley 306, the third synchronous pulley 309, and the fourth synchronous pulley 3011 are all provided with tooth grooves, while the inner walls of the first synchronous belt 305 and the second synchronous belt 3010 are provided with teeth that mesh with the tooth grooves, thereby improving the transmission effect.

[0037] It also includes a vibrating material guiding mechanism 40, which includes a material guiding cover 401 and a vibrating motor 404. A reinforcing plate 403 is fixedly connected to one side of the material guiding cover 401, and the vibrating motor 404 is located on one side of the reinforcing plate 403. The other three sides of the material guiding cover 401 are open, and the material guiding cover 401 is located at the end of the first screen hole 204 of the first material guiding cylinder 201. The material guiding cover 401 is located directly below the material transfer channel 205.

[0038] Specifically, by setting up the vibration motor 404, the guide cover 401 can transmit vibration to the first guide cylinder 201 and the transfer channel 205, thereby increasing the screening effect on the grain and accelerating the efficiency of impurities being screened out through the first sieve hole 204 and the second sieve hole 206.

[0039] The lower surface of the guide cover 401 is provided with a discharge port 405. Multiple sets of connecting bolts 402 are inserted into both sides of the guide cover 401 adjacent to the reinforcing plate 403. The multiple sets of connecting bolts 402 pass through the guide cover 401 and are bolted to the first guide cylinder 201. The discharge port 405 facilitates the collection of sand and gravel impurities screened out, and the multiple sets of connecting bolts 402 facilitate the disassembly and assembly of the guide cover 401, thus improving its practicality.

[0040] In use, the grains to be screened are fed into the feed hopper 203. Then, the drive motor 301 and the vibration motor 404 are started through the control terminal of the rice milling machine. The drive motor 301 drives the first rotating shaft 302 to rotate, which causes the first synchronous pulley 304 to drive the second synchronous pulley 306 to rotate via the first synchronous belt 305. This causes the third synchronous pulley 309 on the second rotating shaft 307 to drive the fourth synchronous pulley 3011 to rotate via the second synchronous belt 3010. This causes the stirring rod 3013 on the third rotating shaft 3012 to stir the grains and prevent them from piling up. When the feed hole 202 is blocked, the second rotating shaft 307 drives the second spiral blade 308 to transport the grain to the transfer channel 205. During the transport process, impurities and sand in the grain will be screened out through the first screen hole 204 and enter the guide cover 401. At the same time, the grain entering the transfer channel 205 will be further screened out of impurities and sand by the second screen hole 206, so that the screened grain enters the second guide cylinder 207. Under the action of the first spiral blade 303, it is convenient to lift and transport the grain into the rice huller, which improves the efficiency of grain transport.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
