Description

Technical Field

[0001] This application relates to the field of grain processing equipment technology, and in particular to rice milling equipment for large-scale vertical rice processing. Background Technology

[0002] In the rice processing process, rice milling equipment is an important machine for removing the husk from paddy rice and improving the surface smoothness of rice grains. Currently, widely used rice milling equipment usually adopts a structure that combines a grinding roller and a screen. The grinding roller is located in the center, and the screen is fitted around the outside of the grinding roller. Under the mechanical force and friction generated by the high-speed rotation of the grinding roller, the husk of the paddy rice is removed and the brown rice is finely milled.

[0003] However, because the screen is mounted outside the grinding roller, it is prone to wear and clogging during long-term operation, affecting the hulling efficiency and the quality of the finished rice, requiring regular inspection and replacement. This structure, however, makes the screen disassembly and assembly process complex, and replacement operations time-consuming and labor-intensive, severely impacting the equipment's operating efficiency and ease of maintenance. Therefore, a large-scale vertical rice milling machine is proposed. Summary of the Invention

Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] This application discloses a large-scale vertical rice milling device, including a housing 1, a rotating mechanism, a feeding box 2, a screen cylinder 12, a milling roller 13, and a discharge box 11. The milling roller 13 is located inside the housing 1. The feeding box 2 and the screen cylinder 12 are partially sleeved on the outside of the milling roller 13. The inlet of the feeding box 2 is located above the milling roller 13 and extends to the outside of the housing 1. The feeding box 2 is in contact with but not connected to the screen cylinder 12, and the contact surfaces of the feeding box 2 and the screen cylinder 12 are connected. The outer surface of the housing 1 away from the feeding box 2 is set as an opening and connected to a side plate 5 by an opening and closing mechanism. A connecting mechanism is provided between the side plate 5 and the screen cylinder 12. The rotating mechanism is located at one end of the milling roller 13 and is used to drive the milling roller 13 to rotate. The discharge port of the discharge box 11 is located below the milling roller 13 and extends to the outside of the housing 1.

[0024] Furthermore, the rotating mechanism includes a motor 6, which is fixedly mounted on the outer surface of the housing 1 by a mounting bracket. The output shaft of the motor 6 passes through the housing 1 and is fixedly connected to the roller 13. A first transmission wheel 7 is fixedly connected to the output shaft of the motor 6. A second transmission wheel 8 is provided below the first transmission wheel 7. A belt 9 is fitted on the outer surface of the first transmission wheel 7 and the second transmission wheel 8. One end of the second transmission wheel 8 passes through the interior of the housing 1 and is provided with a suction fan 14. A chip discharge port 10 is provided on the surface of the housing 1 below the suction fan 14.

[0025] Furthermore, the milling roller 13 is cylindrical, and the surface of the milling roller 13 is provided with threads to guide the rice through the screen cylinder 12.

[0026] Furthermore, the surface of the sieve cylinder 12 is provided with evenly distributed wiping holes, and the wiping holes are inclined at 30°~45° toward the inside of the sieve cylinder 12. The inclined wiping holes can enhance the friction between the rice and the milling surface and promote the peeling of the rice husk.

[0027] In this embodiment, the rice enters the equipment through the feed inlet of the feed box 2. Since the surface of the grinding roller 13 is threaded, the rice is guided into the screen cylinder 12 under the action of the rotation of the grinding roller 13, and the hulling and grinding process begins.

[0028] The milling roller 13 is driven by the motor 6 to rotate at high speed, and is driven by the belt 9 between the first transmission wheel 7 and the second transmission wheel 8, which drives the suction fan 14 to run synchronously. Under the action of friction and mechanical force between the milling roller 13 and the screen cylinder 12, the husk of the rice is removed, and the brown rice is further milled to reach the required quality of polished rice.

[0029] The milled rice grains are discharged from the equipment through the discharge port of the discharge box 11. At the same time, the suction fan 14 sucks in the debris generated during the rice milling process and discharges it through the debris discharge port 10 on the surface of the shell 1, ensuring the cleanliness of the equipment interior and improving processing efficiency.

[0030] In addition, the structure and working principle of the suction fan 14 are all existing conventional technologies, and will not be elaborated here. In production, the appropriate suction fan 14 model should be selected according to the actual situation.

[0031] Furthermore, the opening and closing mechanism includes slide blocks 3 fixedly installed on both sides of the housing 1, and slide plates 20 fixedly connected to both sides of the side plate 5. The two sets of slide plates 20 are respectively inserted into the two sets of slide blocks 3. Bolts 4 are inserted into the outer surface of the slide block 3 near the opening, and the bolts 4 abut against the surface of the slide plate 20.

[0032] Furthermore, the connecting mechanism includes an insert plate 18 fixedly installed on the top of the screen cylinder 12, a socket 17 fixedly connected to the surface of the side plate 5, the insert plate 18 and the socket 17 being inserted into each other, and flexible protrusions are provided on both sides of the top of the insert plate 18.

[0033] Furthermore, both the insert plate 18 and the socket 17 are provided with insertion holes 19. An insertion rod 16 is fixedly connected inside the housing 1. The insertion rod 16 is inserted into the insertion hole 19, and the insertion direction of the insertion rod 16 into the insertion hole 19 is parallel to the insertion direction of the slide plate 20 and the slide block 3.

[0034] In this embodiment, since the screen cylinder 12 is sleeved outside the roller 13 and is in contact with but not fixedly connected to the feed box 2, the disassembly and replacement of the screen cylinder 12 is relatively simple. In specific operation, firstly, loosen the bolts 4 on both sides of the side plate 5 so that the slide plate 20 slides out of the slide block 3, thereby opening the side plate 5; at the same time, the screen cylinder 12 is removed from the housing 1, the insertion rod 16 is separated from the insertion hole 19, and then the insertion plate 18 is removed from the socket 17, so that the screen cylinder 12 can be removed. After replacement or maintenance, it is installed in the reverse order.

[0035] It should be noted that the sieve cylinder 12 and the insert plate 18 in this application are integrated and can be replaced as a whole.

[0036] In this embodiment, the flexible protrusion can be made of flexible rubber material, which can play a certain limiting role. When the plug plate 18 and the socket 17 are engaged, the flexible protrusion can fix the plug plate 18 and the socket 17 relatively, and the plug holes 19 on the plug plate 18 and the socket 17 are aligned with the plug rod 16.

[0037] Furthermore, a support rod 15 is fixedly connected to the surface of the side plate 5. A groove adapted to the support rod 15 is opened at the center of one end of the roller 13 near the side plate 5. The support rod 15 is inserted into the groove, and the support rod 15 is inserted into the groove at the end of the roller 13, which enhances the stability of the roller 13 during high-speed rotation and avoids the impact of vibration on the processing quality.

[0038] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
