Description

Technical Field

[0001] The present invention relates to the technical field of conveying devices, in particular to rice processing equipment capable of controlling feeding. Background Art

[0002] The rice processing process mainly includes cleaning, hulling, rice milling, and finished product finishing. Among them, rice milling is the key step to remove the cortex of the brown rice surface to obtain white rice. During the entire rice processing process, the state of the rice husk has an important influence on the quality of the final rice. Especially in the rice milling process, keeping the rice husk at a certain moisture level can significantly improve the processing effect. For example, the dry rice husk increases its hardness, and the rice milling machine roller needs to overcome greater resistance when rolling the rice husk and brown rice, which will increase the energy consumption of the equipment and reduce the speed and efficiency of rice milling. At the same time, too low moisture content will make the rice husk dry and fragile. During the rice milling process, the gap between the rice husk and the brown rice will be The friction force increases. This greater friction force will cause the brown rice to be subjected to greater external force, which will easily cause the brown rice to break, thereby increasing the proportion of broken rice. Too much broken rice will affect the appearance quality and taste of the rice, reduce the grade and economic value of the rice, and in addition, the increased wear of equipment components will shorten the service life of the equipment and increase the maintenance cost of the equipment; too low moisture content of rice husk may cause more heat to be generated during the rice milling process. If this heat cannot be dissipated in time, the temperature of the brown rice will rise, which will affect the quality of the rice. High temperature may cause the starch in the rice to gelatinize and the protein to denature, resulting in a worse taste of the rice, changes in the steaming and cooking characteristics, and a weakening of the aroma.

[0017] Reference Figures 1-8The present invention proposes a rice processing device with controllable feeding, comprising a feeding pipe 1, a feeding trough 2 is provided at the top of the feeding pipe 1, a feeding channel connected to the bottom of the feeding trough 2 is provided in the feeding pipe 1, and during rice milling, rice is poured into the feeding trough 2, and the rice enters the feeding channel by gravity, and a rice humidity detection mechanism and a moisturizing mechanism are installed in the feeding channel, the rice humidity detection mechanism is used to detect the humidity of rice and rice husks in the feeding channel, and the rice humidity detection mechanism is an infrared humidity detection device 7, and the detection probe of the infrared humidity detection device 7 is installed at the top of the feeding channel. The inner wall of the rice enters the feeding channel and is transported downward and the humidity of the rice husk is detected. After the humidity of the rice husk is detected, the rice is moistened by the moistening mechanism, so that the rice husk absorbs water and softens, which is convenient for rice milling. The moistening mechanism is used to replenish water according to the humidity of the rice husk detected by the rice humidity detection mechanism; the moistening mechanism includes a heat preservation box 4 and a heat insulation plate 5. An installation groove is provided inside the bottom of the feeding channel, the heat preservation box 4 is fixedly installed in the installation groove, and the heat insulation plate 5 is installed on the top surface of the heat preservation box 4. The top surface of the heat insulation plate 5 coincides with the bottom conveying surface of the feeding channel, and the heat insulation plate 5 is provided with a heat preservation box 4 connected to the heat preservation box 4. There are multiple air outlet holes 6, and the number of air outlet holes 6 is multiple. The multiple air outlet holes 6 are arranged in a matrix on the insulation board 5. The feeding pipe 1 is equipped with an air inlet pipe 8 connected to the insulation box 4. During the specific operation, steam is generated by an external electric steam generator and enters the insulation box 4 through the air inlet pipe 8. The flow rate of the steam can be controlled by controlling the operation of the air pump, so that a corresponding amount of steam is added according to the humidity of the rice husk, so that the effect of moistening the rice is optimal and the occurrence of excessive moisture is reduced. The steam then enters the feeding channel through the air outlet holes 6 and contacts the rice to moisten and soften the rice husk (usually requires It takes 10-30 minutes to moisten the rice husks. When the wetness of the rice husks is not required to be high, it can be completed in 10-15 minutes). A conveying channel is also provided in the feeding pipe 1 after moistening. A conveying auger 3 is rotatably installed in the conveying channel. A discharge port connected to the conveying channel is provided at the bottom of the feeding pipe 1. A motor 23 for driving the conveying auger 3 to rotate is installed in the feeding pipe 1. The motor 23 drives the conveying auger 3 to rotate and control the feeding of the moistened rice. The speed of the conveying auger 3 can be controlled to control the feeding amount. The rice transported by the conveying auger 3 enters the discharge port and enters the next process.

[0018] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown in, the moistening mechanism also includes a movable plate 9, a conical plug 10 and an electric push rod 11; the movable plate 9 is slidably installed in the heat preservation box 4, and the conical plug 10 is fixedly installed on one side of the movable plate 9. The end of the conical plug 10 can be inserted into the air outlet 6 to form an annular channel. The conical plug 10 is inserted into the air outlet 6 to adjust the cross-sectional area of the annular channel. The electric push rod 11 is used to drive the movable plate 9 to slide in the heat preservation box 4. When moisturizing, when the steam is discharged through the annular channel, the movable plate 9 and the conical plug 10 can be pushed synchronously by the work of the electric push rod 11, so that the position of the conical plug 10 in the air outlet 6 is changed, so that the cross-sectional area of the annular channel is changed, thereby controlling the amount of steam passing through, and the amount of steam discharged can be adjusted according to the moisture content of the rice husk, ensuring the moistening effect of the rice husk and reducing excessive moisture. In addition, the design of the conical plug 10 can also push out the rice stuck in the air outlet 6, reducing the situation where the tip of the rice is stuck in the air outlet 6 and causing blockage.

[0019] like Figure 2 and Figure 3 As shown in the figure, the humidifying mechanism also includes a drain pipe 12; the water inlet end of the drain pipe 12 is connected to the insulation box 4. In actual conditions, after the steam enters the insulation box 4, it may condense into water droplets on the inner wall of the insulation box 4 and accumulate in the insulation box 4. Long-term accumulation may cause the water to flow out through the air outlet 6, resulting in excessive water mixing on the rice husk, affecting the moisture condition of the rice husk. Therefore, a drain pipe 12 is provided, and the amount of water in the insulation box 4 is detected by a sensor, and the accumulated water is discharged through the drain pipe 12 to discharge the condensed water droplets to ensure the humidifying effect.

[0020] like Figure 2 and Figure 3 As shown in the figure, a feeding mechanism is also installed in the feeding channel, which is used to push the rice in the feeding channel. In actual conditions, after the steam enters the feeding channel, the steam may condense into water droplets, and the rice will stick to the feeding channel, affecting the feeding of the rice. Therefore, the rice in the feeding channel is transported to the conveying channel through the feeding mechanism.

[0021] like Figure 2 and Figure 3 As shown in the figure, the feeding mechanism includes a conveyor belt 13 and a scraper 14; the conveyor belt 13 is installed in the discharge channel, and the conveying surface of the conveyor belt 13 is arranged parallel to the conveying direction of the discharge channel. There are multiple scrapers 14, and multiple scrapers 14 are arranged at intervals on the conveyor belt 13. The conveyor belt 13 drives the multiple scrapers 14 to rotate in a circular manner, and the circularly rotating scrapers 14 scrape the rice in the discharge channel, thereby ensuring that the rice in the discharge channel is transported.

[0022] like Figure 2 、 Figure 3 、 Figure 4 and Figure 8 As shown in , an elastic sheet 15 is provided between the scraper 14 and the conveyor belt 13. The scraper 14 is arranged perpendicular to the conveying surface of the conveyor belt 13. The top surface of the heat insulation plate 5 is fixedly connected with an obstruction protrusion 16. When the conveyor belt 13 drives the scraper 14 to rest against the obstruction protrusion 16, the elastic sheet 15 bends, and the scraper 14 passes over the obstruction protrusion 16. The elastic sheet 15 rebounds and resets. The elastic sheet 15 drives the scraper 14 to rebound and throws off the rice stuck on the scraper 14. In actual conditions, after the steam enters the discharge channel, although there is a coordinated conveying effect of the scraper 14 and the conveyor belt 13, steam may condense into water droplets on the scraper 14. , there will be rice stuck on the scraper 14, so when the scraper 14 scrapes the rice to the connection point of the discharge channel and the conveying channel, the scraper 14 rests on the obstruction protrusion 16, and the corresponding elastic sheet 15 bends and deforms. As the conveyor belt 13 continues to work, it drives the scraper 14 to move synchronously until the scraper 14 slides over the obstruction protrusion 16. Under the rebound action of the bent elastic sheet 15, the scraper 14 rebounds and resets. When the scraper 14 rebounds and resets following the elastic sheet 15, the sticky rice on the scraper 14 will also be thrown out into the conveying channel, thereby reducing the rice sticking to the scraper 14 and ensuring the conveying of the rice.

[0023] like Figure 2 and Figure 3 As shown in the figure, the bottom inner wall of the feed trough 2 is arranged inclined, and a fluctuating plate 17 is rotatably installed on the bottom inner wall of the feed trough 2. A transmission mechanism is provided between the conveying auger 3 and the fluctuating plate 17. When the conveying auger 3 rotates, the transmission mechanism can convert the rotation action of the conveying auger 3 into a reciprocating shaking motion of the fluctuating plate 17. In actual conditions, the conveying auger 3 controls the feeding amount of rice. When feeding, the bottom inner wall of the feed trough 2 may be subjected to the gravity pressure of the rice above the feed trough 2, and the rice on the bottom inner wall of the feed trough 2 cannot slide down. The fluctuating plate 17 is driven by the transmission mechanism to shake back and forth, so that the mutual movement between the rice is increased, thereby ensuring smooth feeding of the rice, reducing the blockage caused by the mutual squeezing and accumulation of the rice, promoting uniform feeding of the rice, and also increasing the feeding speed.

[0024] like Figure 2 and Figure 3The transmission mechanism shown in the figure includes a No. 1 end face bevel gear block 18, a No. 2 end face bevel gear block 19, a lifting rod 20 and a downward pressure spring 21; a rotating groove is provided in the feeding pipe 1, and the rotating shaft of the conveying auger 3 is connected to the No. 1 end face bevel gear block 18, the No. 1 end face bevel gear block 18 is located in the rotating groove, the No. 2 end face bevel gear block 19 is engaged with the No. 1 end face bevel gear block 18, and the top bevel gear of the No. 2 end face bevel gear block 19 can slide with the bottom bevel gear of the No. 1 end face bevel gear block 18 The ends of the No. 1 end face bevel gear block 18 and the No. 2 end face bevel gear block 19 are circumferentially arranged with bevel gear blocks, and the lifting rod 20 is fixedly connected to the top of the No. 2 end face bevel gear block 19. The top of the lifting rod 20 passes through the feeding pipe 1 and abuts against the bottom surface of the fluctuating plate 17. The lifting rod 20 can only move up and down in the feeding pipe 1 and cannot rotate. The pressing spring 21 is sleeved on the lifting rod 20, and the two ends of the pressing spring 21 are respectively connected to the top inner wall of the rotating groove and the No. 2 end face bevel gear block 19. The top surface of the end face bevel gear block 19 is abutted, and the motor 23 is driven to drive the conveying auger 3 to rotate and convey the rice. When the conveying auger 3 rotates, its rotating shaft is driven to rotate synchronously, and its rotating shaft drives the No. 1 end face bevel gear block 18 to rotate synchronously. The bevel gear block on the end face of the No. 1 end face bevel gear block 18 and the bevel gear block on the end face of the No. 2 end face bevel gear block 19 slide together, so that the No. 2 end face bevel gear block 19 moves up and down in the rotating groove. When the No. 2 end face bevel gear block 19 rises and falls, it will drive the lifting rod 20 The lifting and lowering movements are carried out synchronously, and the fluctuating plate 17 is lifted up by the lifting rod 20. Under the action of the gravity of the rice and its own gravity, when the lifting rod 20 descends, the fluctuating plate 17 also descends synchronously, thereby realizing reciprocating shaking, thereby ensuring the discharge of rice in the feed trough 2. In addition, when the rotation speed of the conveying auger 3 becomes faster, the conveying speed of the rice is increased, and at the same time, the reciprocating shaking frequency of the fluctuating plate 17 becomes larger, thereby increasing the discharge speed of the rice in the feed trough 2.

[0025] like Figure 2 and Figure 3 As shown in the figure, a reset groove is provided on the bottom surface of the feed trough 2, and a reset spring 22 is installed in the reset groove. The two ends of the reset spring 22 are respectively connected to the bottom surface of the fluctuating plate 17 and the inner wall of the end of the reset groove. The stretched reset spring 22 pulls the fluctuating plate 17 to rotate and fall to reset. When the amount of rice in the feed trough 2 is small, the reset movement of the fluctuating plate 17 is ensured.
