Description

Technical Field

[0001] This invention belongs to the field of rice milling machine technology, specifically a rice milling machine with a feeding and guiding mechanism. Background Technology

[0002] Rice refers to paddy rice that has undergone processing such as hulling and bran removal. Rice is one of the main staple foods for humans and one of the most important food crops in the world. Rich in nutrients such as carbohydrates, protein, vitamins, and minerals, rice is an indispensable source of nutrition in people's daily diet.

[0003] Rice can be processed and cooked in various ways, such as boiling and steaming, to make rice, porridge, and other foods. In many Asian countries, rice is a staple food, and people eat it cooked with various dishes. Rice can also be processed into rice noodles, rice cakes, and rice grains for making various foods, such as rice noodles, rice cakes, and pastries. The processing methods and uses of rice vary, making it widely used in a variety of dishes and cooking methods.

[0004] In the rice processing, milling is necessary to break down rice grains into different sizes for later use. Current rice milling machines are not ideal for sieving the milled rice grains, resulting in inconsistent grain sizes that affect usability. Furthermore, guiding the rice during feeding is difficult, and the rice grains easily create dust during the feeding process. Therefore, improvements are needed. Summary of the Invention

[0009] Preferably, the circulation mechanism includes a screen, which is fixedly connected inside the housing. A fixed cylinder is fixedly connected to the left end of the housing, and a feed inlet is fixedly connected to the lower right side of the fixed cylinder. The feed inlet is fixedly connected to the housing. A guide plate is fixedly connected to the upper right side of the fixed cylinder and is fixedly connected to the housing.

[0010] Preferably, one end of the first spring is fixedly connected to the cylinder, and the other end of the first spring is fixedly connected to the slide rod. The first spring is designed so that its force can be applied to the slide rod.

[0011] Preferably, the feeding mechanism includes a third motor. The third motor is fixedly connected to the right end of the housing. A fixed rod is fixedly connected to the lower end of the output end of the third motor. A vertical rod is rotatably connected to the inside of the fixed rod via a bearing. A hinge rod is rotatably connected to the outside of the vertical rod via a bearing. A connecting frame is hinged to the outside of the hinge rod. An impact block is fixedly connected to the inside of the connecting frame. The impact block contacts the feeding port. A guide rod is fixedly connected to the left end of the connecting frame.

[0015] The beneficial effects of this invention are as follows: This invention relates to a rice milling machine with a feeding and guiding mechanism, which has the characteristics of screening the milled rice and guiding the rice feeding process to prevent dust. In specific use, compared with traditional rice milling machines with feeding and guiding mechanisms, this rice milling machine with feeding and guiding mechanism has the following beneficial effects:

[0016] Firstly, the screen is designed to separate the rice after milling, ensuring that thoroughly milled material can be recycled. The feed inlet allows for the recovery of incompletely milled rice. The rotation of the reamer allows the incompletely milled material to be reintroduced into the chamber for milling, achieving material circulation and ensuring complete milling of the rice. Furthermore, during the feeding process through the cylinder, the plug can move back and forth vertically, allowing the annular seat to open and close continuously. This enables the batch feeding of rice to be milled, avoiding the impact of excessive rice raw material addition on the uniformity of milling.

[0017] Secondly, by designing the discharge port and extension cylinder, the crushed material can be discharged. Under the action of the third motor, the fixed rod, vertical rod and hinge rod can be driven to rotate, thereby realizing the reciprocating movement of the connecting frame in the horizontal direction. This allows the impact block to impact the discharge port, causing the discharge port to vibrate and avoid blockage during discharge, thus improving discharge efficiency. Through the insertion of the ball and the groove, the relative position of the extension cylinder and the discharge port can be adjusted and fixed. When the handle is pulled to move the extension cylinder, the relative position of the extension cylinder and the discharge port can be adjusted, which facilitates the guidance of the discharge process at different heights and avoids dust caused by different heights of the collection container.

[0031] The feeding mechanism 8 includes a second motor 81. The second motor 81 is fixedly connected to the right end of the cylinder 13. The output end of the second motor 81 is rotatably connected to the cylinder 13. A rotating shaft 82 is fixedly connected to the left end of the output end of the second motor 81. The rotating shaft 82 is rotatably connected to the cylinder 13 via a bearing. A top block 83 is fixedly connected to the lower end of the rotating shaft 82. A protrusion 84 is in contact with the lower end of the top block 83. A sliding rod 85 is fixedly connected to the lower end of the protrusion 84. The sliding rod 85 slides against the cylinder 13. A moving connection is provided. A first spring 86 is installed inside the cylinder 13. One end of the first spring 86 is fixedly connected to the cylinder 13, and the other end is fixedly connected to a sliding rod 85. The design of the first spring 86 allows its force to act on the sliding rod 85. A connecting rod 87 is fixedly connected to the lower end of the sliding rod 85, and a blocking block 88 is fixedly connected to the lower end of the connecting rod 87. An annular seat 89 is slidably fitted onto the outer side of the blocking block 88, and the annular seat 89 is fixedly connected to the cylinder 13. A feeding mechanism 8 is designed to feed rice raw materials into the box 1 in batches.

[0032] The feeding mechanism 9 includes a third motor 91. The third motor 91 is fixedly connected to the right end of the housing 1. A fixed rod 92 is fixedly connected to the lower end of the output end of the third motor 91. A vertical rod 93 is rotatably connected to the inside of the fixed rod 92 via a bearing.

A groove 97 is formed inside the feeding port 6. A ball bearing 98 is movably sleeved inside the groove 97. There are multiple grooves 97. The grooves 97 are evenly distributed inside the feeding port 6. By designing multiple grooves 97, the balls 98 can roll into the grooves 97 at different positions. The balls 98 are slidably connected to the extension cylinder 10. A slider 99 is movably sleeved on the outside of the balls 98. A guide rod 991 is fixedly connected to the lower end of the slider 99. Both the slider 99 and the guide rod 991 are slidably connected to the extension cylinder 10. A crossbar 992 is slidably sleeved inside the guide rod 991. The crossbar 992 is fixedly connected to the extension cylinder 10. A second spring 993 is provided on the outside of the crossbar 992. One end of the second spring 993 is fixedly connected to the guide rod 991, and the other end of the second spring 993 is fixedly connected to the extension cylinder 10. By designing the second spring 993, the force of the second spring 993 can act on the guide rod 991. By designing the feeding mechanism 9, the rice feeding process can be guided.

[0033] The invention is used as follows: When in use, rice raw material is first added into the cylinder 13 through the feeding port 14. At the same time, the output end of the second motor 81 drives the rotating shaft 82 to rotate. The rotating shaft 82 drives the top block 83 to rotate, causing the top block 83 to separate from the protrusion 84. At this time, under the elastic action of the compressed first spring 86, an upward counter-force is given to the slide rod 85, causing the connecting rod 87 to pull the blocking block 88 to separate from the annular seat 89. At this time, the rice inside the cylinder 13 will be conveyed into the box 1 through the cylinder 13. When the top block 83 contacts the protrusion 84 again, the blocking block 88 can be pressed into the annular seat 89 to re-seal it. The annular seat 89 can be opened and closed continuously, which can realize the batch feeding of rice to be crushed and avoid the rice raw material being added too much at one time, which would affect the uniformity of crushing.

[0034] When the rice enters the box 1, the output of the drive motor 4 drives the rice milling roller 5 to rotate and mill the rice. The milled rice is filtered and screened by the screen 71 to ensure that the thoroughly milled material can be recycled. The rice that is not fully milled will move along the inclined surface of the screen 71 and enter the fixed cylinder 72 through the feed port 73. At the same time, the output of the first motor 75 drives the rotating rod 76 and the reamer 77 to rotate, which can convey the rice upward and then feed it back into the box 1 through the guide plate 74. The incompletely milled material can be poured back into the box 1 for milling, realizing the recycling and milling of the material and ensuring that the rice is fully milled.

[0035] After the rice is crushed, the material is discharged outward through the discharge port 6 and the extension cylinder 10. During the feeding process, the third motor 91 works simultaneously. The output end of the third motor 91 drives the fixed rod 92 to rotate, the fixed rod 92 drives the vertical rod 93 to rotate, and the vertical rod 93 drives the hinge rod 94 to deflect. The hinge rod 94 pulls the connecting frame 95 to move back and forth in the horizontal direction. The connecting frame 95 drives the guide rod 994 to slide along the guide seat 995. The connecting frame 95 can drive the impact block 96 to move in the horizontal direction, so that the impact block 96 can impact the discharge port 6, which can make the discharge port 6 vibrate to avoid blockage during feeding and improve feeding efficiency.

[0036] When the position of the extension cylinder 10 needs to be adjusted, pull the handle 11. The handle 11 moves the extension cylinder 10, which in turn moves the ball bearing 98 along the groove 97. The arc surface inside the groove 97 will squeeze and push the ball bearing 98 to roll horizontally. The ball bearing 98 moves the slider 99, which in turn moves the guide rod 991 along the crossbar 992 and squeezes the second spring 993, which can separate the ball bearing 98 from the groove 97. As the extension cylinder 10 moves, the second spring 993 will give the guide rod 991 an outward push. The guide rod 991 will push the slider 99 and the ball bearing 98 to reset, allowing the ball bearing 98 to roll into the groove 97 at another position. This allows the relative position of the extension cylinder 10 and the discharge port 6 to be adjusted and fixed, which facilitates different height guidance during the discharge process and avoids dust generation caused by different heights of the collection container.
