Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of rice hulling machines, and in particular to a rice hulling machine. Background Technology
[0002] Rice is a finished product made from paddy through processes such as cleaning, hulling, milling, and finishing. Rice contains nearly 64% of the nutrients in paddy and more than 90% of the nutrients needed by the human body. During the processing of rice, it needs to be hulled, and a hulling device is required in the process of hulling rice.
[0003] For example, the utility model disclosed in authorization announcement number CN219663771U discloses a rice hulling device, including a hulling box, a feeding hopper at the top of the hulling box, a discharge port fixedly connected inside the feeding inlet, and a discharge port at the bottom of the hulling box, with a discharge pipe fixedly connected inside the discharge port. This utility model, through the setting of a vibration unit, enables a motor to drive a driven rod to rotate, which in turn drives a movable rod to rotate, which in turn drives a cam to rotate. When the cam's protruding part rotates onto the sieve screen, the sieve screen moves downwards. When the protrusions move away, the sieve moves upward, vibrating and sieving the rice after it has been crushed by the rollers, thus dispersing the rice and bran. As the rice and bran fall from the sieve, the bran discharge fan blows the bran, causing it to fall into the bran collection box, while the rice flows out from the discharge pipe. This disperses the rice and bran, thereby improving the separation effect. However, during the operation of this device, some impurities such as bran adhere to the surface of the rollers during the crushing process, and the device cannot effectively clean the rollers. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a rice hulling machine, which can solve the technical problem that when the rollers are used to crush rice, some rice bran and other impurities will adhere to the surface of the rollers, and the device cannot effectively clean the rollers.

[0010] As a preferred embodiment of this utility model, a switch door is provided on one side of the box.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By activating the electric telescopic rod, the electric telescopic rod drives the fixed block to move to one side. The movement of the fixed block, in turn, drives the connecting plate and the brush layer to move to one side until the brush layer contacts the roller shaft. At the same time, two motors are activated, and the two motors drive the two roller shafts to rotate.

[0019] Please refer to Figures 1-3 As shown, this utility model provides a rice hulling machine. A filter plate 15 is provided inside the housing 1. A pair of vibrators 16 are provided at the lower end of the filter plate 15. The vibrators 16 are equipped with batteries for power supply. By starting the vibrators 16, the rice on the filter plate 15 can fall to the bottom of the housing 1. A suction pipe 17 is provided on one side of the housing 1. One end of the suction pipe 17 is connected to a collection box 18. A filter screen 19 is provided inside the collection box 18. One side of the collection box 18 is connected to a blower 20 through a pipe. A feed pipe 21 is provided at the upper end of the housing 1. A door 22 is provided on one side of the housing 1.
[0020] When in use, by starting the fan 20, the rice bran on the filter plate 15 can be sucked into the suction pipe 17 and collected in the collection box 18 through the suction pipe 17. The filter screen 19 can also block the rice bran to a certain extent.
[0021] As a further implementation of this embodiment, such as Figures 1-4As shown, an electric telescopic rod 2 is provided on one side of the housing 1. A fixing block 3 is fixedly connected to the output end of the electric telescopic rod 2. A slot 4 is provided at the lower end of the fixing block 3. A plug 5 is inserted into the slot 4. A connecting plate 6 is fixedly connected to the lower end of the plug 5. A brush layer 7 is provided at the lower end of the connecting plate 6. A limiting groove 8 is provided on one side of the connecting plate 6. A bracket 9 is fixedly connected to one side of the fixing block 3. A crossbar 10 is passed through the bracket 9. A limiting block 11 is fixedly connected to one side of the crossbar 10. A spring 12 is fixedly connected between the limiting block 11 and the bracket 9. A pair of motors 13 are provided on one side of the housing 1. The two motors 13 are located at the same height. The output end of the motor 13 passes through the housing 1 and is fixedly connected to the roller shaft 14. One end of the roller shaft 14 is rotatably connected to the housing 1. The motors 13 and the electric telescopic rod 2 on this device are electrically connected to the power supply to ensure that it can be used normally.
[0022] In use, by activating the electric telescopic rod 2, the electric telescopic rod 2 drives the fixed block 3 to move to one side. The movement of the fixed block 3 in turn drives the connecting plate 6 and the brush layer 7 to move to one side until the brush layer 7 contacts the roller shaft 14. At the same time, the two motors 13 are activated, and the two motors 13 drive the two roller shafts 14 to rotate. During the rotation of the roller shafts 14, the brush layer 7 can brush off the rice bran adhering to the roller shafts 14, thus effectively cleaning the roller shafts 14. In addition, by pulling the crossbar 10, the crossbar 10 drives the limiting block 11 to move, and at the same time the spring 12 contracts until the limiting block 11 leaves the limiting groove 8, so that the insert 5 can be removed from the slot 4. At the same time, the connecting plate 6 with the brush layer 7 can be disassembled and the brush layer 7 can be cleaned.
[0023] Specific working principle: In use, firstly, start the two motors 13, which drive the roller 14 to rotate. Then, add rice into the box 1. The roller 14 can crush the falling rice, separating the rice from the bran, and the rice falls onto the filter plate 15. At the same time, start the fan 20. Under the action of the fan 20, the rice bran on the filter plate 15 is sucked into the suction pipe 17 and then into the collection box 18 for centralized collection. The filter screen 19 can also block the rice bran to a certain extent. Finally, the collection box 18 can be opened to remove the rice bran. When it is necessary to clean the roller 14, the electric telescopic rod 2 can be started, which will drive the fixed block 3 to one side. The fixed block 3 moves into... The connecting plate 6 and the brush layer 7 are moved to one side until the brush layer 7 contacts the roller 14. At the same time, the two motors 13 are started, and the two motors 13 drive the two rollers 14 to rotate. During the rotation of the rollers 14, the brush layer 7 can brush off the rice bran adhering to the rollers 14, thus cleaning the rollers 14 effectively. In addition, by pulling the crossbar 10, the crossbar 10 moves the limiting block 11, and the spring 12 contracts until the limiting block 11 leaves the limiting groove 8, so that the insert 5 can be removed from the slot 4. At the same time, the connecting plate 6 with the brush layer 7 can be disassembled and the brush layer 7 can be cleaned. Finally, the rice at the bottom of the box 1 can be taken out by opening the switch door 22.
