Description

Technical Field

[0001] This utility model relates to the technical field of rice milling mechanisms, and in particular to a rice milling mechanism for rice flour processing. Background Technology

[0002] Wet rice noodles are a type of fresh rice product made primarily from rice through processes such as washing, soaking, grinding, fermentation, steaming, and pressing. Rice is the core edible part of paddy rice after hulling and milling. The core purpose of this processing is to remove the outer husk, bran, and germ through a rice milling machine, transforming brown rice into white rice to meet consumer needs. The rice milling process first removes the hard husk to obtain brown rice, and then removes the fiber-rich bran layer and easily oxidized germ through whitening, ultimately forming soft, white, refined rice.

[0003] The rice milling mechanism is the core equipment for processing paddy rice into edible rice. It mainly consists of a feeding device, a milling chamber, a discharge system, a bran separation component, and a transmission device. Its core working area is the milling chamber, which contains high-speed rotating milling rollers. Through friction and milling, the bran and germ of the brown rice are removed. The outer part is wrapped with a rice sieve to discharge the rice bran, and the bran separation is achieved by a fan or a bran suction device.

[0004] In traditional rice milling machines, when the moisture content of the paddy is high, some of the water is squeezed out as the paddy is pressed in the feeding box. The adhesion of the paddy is significantly enhanced due to the formation of a liquid film on its surface, which causes some of the paddy to stick together and form clumps. This makes it very easy for arch bridges to form in the feeding box, making it difficult for the paddy to enter the milling chamber for processing. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art where the high moisture content of rice causes arch bridges to form in the feed box, making it difficult for the rice to enter the milling area for processing. Therefore, this invention proposes a rice milling mechanism for rice flour processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rice milling mechanism for rice flour processing includes a feed hopper fixedly installed on a milling chamber, a discharge hopper fixedly installed on the feed hopper, an auger roller rotatably installed inside the discharge hopper, and feeding rods evenly arranged on the cylindrical surface of the auger roller. An arch frame is fixedly installed inside the feed hopper, and a feeding zone is formed between the arch frame and the auger roller. When rice enters the feeding zone, the feeding rods break up the clumps of rice, allowing the rice to enter the discharge hopper. The milling chamber is equipped with an adjusting component to change the flow rate of rice entering the milling chamber.

[0008] To facilitate changing the rice flow rate, preferably, the adjusting component includes feeding plates symmetrically installed in the rice milling chamber, wherein at least one feeding plate is rotatably installed on the side wall of the rice milling chamber, a control shaft is fixedly installed inside the feeding plate, and an adjusting rod is axially slidably sleeved at the end of the control shaft via a sliding key connection, the free end of the adjusting rod extends outside the rice milling chamber, and an unlocking component is provided on the adjusting rod. When the adjusting rod rotates, the adjusting rod drives the control shaft and the feeding plate to rotate.

[0009] To facilitate fixing the adjusting rod, the unlocking component further includes a locking block fixedly installed on the adjusting rod. A locking groove is provided on the rice milling chamber, and the locking block can be fitted into the locking groove. When the adjusting rod moves, the locking block is locked or unlocked from the locking groove.

[0010] To facilitate adjustment of the material feed plate rotation angle, the outer periphery of the locking groove is provided with multiple arc-shaped grooves, which are connected to the locking groove. When the locking block is engaged with the arc-shaped groove, the locking block and the adjusting rod are fixed together.

[0011] To prevent the auger roller from being difficult to rotate, preferably, the arch frame is mainly composed of a support frame and zigzag support bars. The support frame is fixedly installed in the feed hopper, and the support bars are arranged at equal intervals on the support frame. When the rice enters the feed hopper, the rice collides with the support frame, causing the clumps of rice to disperse.

[0012] In order to drive the auger roller, preferably, the shaft of the auger roller extends to the outside of the rice milling chamber, and a drive wheel is fixedly installed on the shaft. The drive wheel is connected to the drive device through belt drive.

[0013] Compared with the prior art, this utility model provides a rice milling mechanism for rice flour processing, which has the following beneficial effects:

[0014] 1. The rice milling mechanism for rice noodle processing uses a screw roller in conjunction with a feeding rod. When the screw roller rotates, the feeding rod breaks up the rice in the feeding area, preventing rice from sticking together and forming an arch bridge in the feed hopper, which would otherwise make it difficult for the rice to enter the milling chamber, thus effectively improving the rice milling efficiency.

[0015] 2. The rice milling mechanism for rice noodle processing uses an adjustable feeding plate to work in conjunction with the milling chamber. By changing the opening and closing gap of the feeding plate, the flow rate of rice can be easily controlled, avoiding the problem of too much rice entering the milling area and reducing milling efficiency.

[0016] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model uses a screw roller in conjunction with a feeding rod to break up the rice in the feeding zone, preventing too much rice from sticking together and forming lumps that would block the feed hopper, thus effectively improving the efficiency of subsequent rice milling.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example:

[0026] Reference Figures 1-5A rice milling mechanism for rice flour processing includes a feed hopper 1 fixedly installed on a milling chamber, and a discharge hopper 2 fixedly installed on the feed hopper 1. The feed hopper 1 has a trapezoidal cross-section. The inclined surfaces on both sides of the feed hopper 1 facilitate the rice to slide down into the discharge hopper 2 under its own weight. An auger roller 3 is rotatably installed inside the discharge hopper 2. Feeding rods 4 are evenly arranged on the cylindrical surface of the auger roller 3. The feeding rods 4 extend along the spiral direction of the auger blades and are evenly arranged to facilitate the breaking up of clumps of rice. A feed hopper 1 is also fixedly installed with... The arch frame 5 is mainly composed of a support frame and zigzag support bars. The support frame is fixedly installed inside the feed hopper 1, and the support bars are evenly distributed on the support frame. When the rice enters the feed hopper 1, the rice collides with the support frame, causing the clumps of rice to disperse, effectively preventing a large amount of clumps of rice from accumulating above the auger roller 3. A feeding zone is formed between the arch frame 5 and the auger roller 3. When the rice enters the feeding zone, the feeding rod 4 breaks up the clumps of rice, allowing the rice to enter the discharge hopper 2. The rice milling chamber is equipped with an adjusting component to change the flow rate of rice entering the rice milling chamber.

[0027] Specifically, the auger roller 3 is used in conjunction with the feeding rod 4. When the auger roller 3 rotates, the feeding rod 4 breaks up the rice in the feeding area, preventing rice from sticking together and forming an arch bridge in the feed hopper 1, which would make it difficult for the rice to enter the rice milling chamber, thus effectively improving the rice milling efficiency.

[0028] The adjusting component includes feeding plates 6 symmetrically installed in the rice milling chamber, wherein at least one feeding plate 6 is rotatably installed on the side wall of the rice milling chamber. A control shaft 7 is fixedly installed inside the feeding plate 6. An adjusting rod 8 is axially slidably sleeved at the end of the control shaft 7 via a sliding key connection. The free end of the adjusting rod 8 extends outside the rice milling chamber. An unlocking component is provided on the adjusting rod 8. When the adjusting rod 8 rotates, it drives the control shaft 7 and the feeding plate 6 to rotate, which facilitates the adjustment of the gap between the two feeding plates 6, thereby controlling the flow rate of rice falling.

[0029] Specifically, the feeding plate 6 is adjusted to work in conjunction with the rice milling chamber. By changing the opening and closing gap of the feeding plate 6, the flow rate of rice can be easily controlled, preventing excessive rice from entering the rice milling area and reducing the rice milling efficiency.

[0030] The unlocking component includes a locking block 9 fixedly installed on the adjusting rod 8. A locking groove is provided on the rice milling chamber. Multiple arc-shaped grooves are provided around the locking groove, and the multiple arc-shaped grooves are connected to the locking groove. The locking block 9 can be fitted into the locking groove. When the adjusting rod 8 is axially displaced to the first working position, the locking block 9 and the locking groove are fitted together to form a snap-fit ​​and realize the circumferential limit of the adjusting rod 8. When the adjusting rod 8 moves to the second working position, the locking block 9 disengages from the locking groove and releases the constraint. At this time, by rotating the adjusting rod 8, the control shaft 7 can be synchronously driven to drive the feeding plate 6 to adjust the angle around the axis of the adjusting shaft, which effectively prevents the problem of the two feeding plates 6 automatically adjusting their opening and closing angles due to the impact of rice on the feeding plate 6.

[0031] The shaft of the auger roller 3 extends to the outside of the rice milling chamber. A drive wheel 11 is fixedly installed on the shaft. The drive wheel 11 is connected to the drive device via belt drive. The drive device mainly consists of a drive motor and multiple pulleys working in conjunction with the belt. The drive motor is a domestic Wolong series motor used to drive the equipment. When the drive motor is working, the pulleys drive the rice milling roller 10 to rotate. Then, through the pulleys on the rice milling roller 10, the drive wheel 11 is driven to rotate via the belt, thereby making the auger roller 3 work, which is convenient to use.

[0032] In this utility model, when the rice is poured into the feed hopper 1, the rice first collides with the arch frame 5. If there are large clumps of rice falling first, they are divided by the zigzag support strips to form small clumps, which are then squeezed into the feeding area. When the auger roller 3 rotates, on the one hand, the auger blades push the rice into the discharge hopper and drop it into the adjusting part. On the other hand, the feeding rod 4 rotates with the auger roller 3 and breaks up the small clumps of rice, avoiding the problem of blockage above the auger roller 3 caused by the sticking of a lot of rice clumps.

[0033] After the rice grains enter the adjusting mechanism, the gap between the feeding plates 6 is adjusted according to the requirements. First, the adjusting rod 8 is pulled out and moved to the second working position. At this time, the locking block 9 disengages from the locking groove. Then, the adjusting rod 8 is rotated so that the control shaft 7 and the feeding plate 6 rotate along the axis of the control shaft 7. After the gap adjustment of the feeding plate 6 is completed, the adjusting rod 8 is pushed again to move it into the first working position. At this time, the locking block 9 engages with the locking groove to fix the position of the feeding plate 6 and prevent the feeding plate 6 from automatically adjusting its angle after being impacted by the rice grains.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
