Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rice processing technology, specifically relating to a rice-brown separator for rice processing. Background Technology
[0002] Rice processing refers to the process of handling paddy rice through a series of steps to produce edible rice. Rice husk separation is a crucial step in rice processing, aiming to separate the paddy husk from the brown rice. This process is primarily achieved through a vibrating sieve physical method, ensuring that the resulting brown rice is ready for further processing.
[0003] A separator is used when separating rice from brown rice. Different types of rice or brown rice have different sizes and weights. However, common separators do not have vibration amplitude adjustment function. The machine cannot adjust the separation method according to the characteristics of rice, which leads to incomplete separation of rice husk and brown rice, or some rice husk is mixed with brown rice, affecting the final separation effect and product quality. Utility Model Content
[0004] The purpose of this invention is to provide a rice husk and brown rice separator for rice processing, which can adjust the vibration amplitude of the separator according to different types of rice, so as to better separate the rice husk and brown rice in the rice, reduce losses and increase the rice yield.
[0005] The specific technical solution adopted by this utility model is as follows:
[0006] A rice processing rice separator includes a base frame and a screening frame. The screening frame is slidably connected to the inner side of the base frame. A screening screen is fixedly connected to the inner wall of the screening frame. A discharge port is opened on one side of the screening frame and is flush with the screening screen. An outlet is opened on the other side of the screening frame and is flush with the bottom of the inner wall of the screening frame. An amplitude adjustment mechanism is provided at the bottom of the screening frame. The amplitude adjustment mechanism includes: a servo motor, which is fixedly installed on the inner side of the base frame; a rotating disk, which is fixedly connected to the output shaft at the top of the servo motor; an adjustment frame, which is connected to the top of the rotating disk via a rotating shaft; a lead screw, one end of which is connected to the inner wall of the adjustment frame via a bearing, and the other end of which extends to the outer side of the adjustment frame; a sliding block, which is threadedly connected to the surface of the lead screw and slidably connected to the inside of the adjustment frame; and a connecting rod, the other end of which is connected to the top of the sliding block via a rotating shaft and the other end of which is connected to the bottom of the screening frame via a rotating shaft.
[0007] Preferably, sliding grooves are provided on both sides of the base frame, and guide rods are fixedly connected to the inner walls of the sliding grooves. Sliding members are fixedly connected to both sides of the screening frame. The sliding members are distributed and sleeved on the surface of the guide rods and slidably connected to the inside of the sliding grooves.
[0008] Preferably, a telescopic spring is movably sleeved on the surface of the guide rod, and the ends of the telescopic spring are respectively fixedly connected to the inner wall of the sliding member and the sliding groove.
[0009] Preferably, a knob is fixedly connected to the end of the lead screw, and the knob is circular in shape.
[0010] Preferably, a flow-blocking plate is fixedly connected to the inner wall of the screening frame, and the bottom of the flow-blocking plate is toothed.
[0011] Preferably, an extension plate is fixedly connected to the bottom of the screening frame, and the extension plate is connected to the end of the connecting rod via a rotating shaft.
[0012] The technical effects achieved by this utility model are as follows:
[0013] In this invention, when screening rice, the material is first added to the screening mesh inside the screening frame. Then, a servo motor is activated, driving a rotating disk. This rotating disk, in turn, drives an adjusting frame at the top. The adjusting frame's rotation simultaneously drives a lead screw and a sliding block. The sliding block's rotation, in turn, causes one end of a connecting rod connected to the rotating shaft to rotate around the rotating disk. Simultaneously, the other end of the connecting rod causes the screening frame to oscillate back and forth inside the base frame. This oscillation of the screening frame effectively screens the material inside. During the screening process... The position of the sliding block can be adjusted to move it away from the axis of the rotating disk, which will cause the screening frame to shake more strongly through the connecting rod. When the sliding block is adjusted closer to the axis of the rotating disk, the shaking amplitude of the screening frame will be reduced. When adjusting the position of the sliding block, the screw can be rotated. When the screw rotates, it will drive the threaded sliding block to slide parallel inside the adjustment frame, so its position can be quickly adjusted. Thus, the shaking amplitude of the screening frame can be flexibly adjusted according to the position of the sliding block. The shaking amplitude can be optimized according to the characteristics of the rice, making the separation effect more precise. Attached Figure Description

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0020] like Figures 1-3 As shown, a rice processing rice separator includes a base frame 1 and a screening frame 101. The screening frame 101 is slidably connected to the inner side of the base frame 1. A screening screen 102 is fixedly connected to the inner wall of the screening frame 101. A discharge port 103 is provided on one side of the screening frame 101 and is flush with the screening screen 102. An outlet port 104 is provided on the other side of the screening frame 101 and is flush with the bottom of the inner wall of the screening frame 101. An amplitude adjustment mechanism is provided at the bottom of the screening frame 101. The amplitude adjustment mechanism includes: a servo motor 201, which is fixedly installed on the inner side of the base frame 1; a rotating disk 202, which is fixedly connected to the output shaft at the top of the servo motor 201; an adjustment frame 203, which is connected to the top of the rotating disk 202 via a rotating shaft; and a lead screw 204, one end of which is connected to the inner wall of the adjustment frame 203 via a bearing, and the other end of which passes through the adjustment frame 203. The outer side of the frame 203; a sliding block 205, which is threaded to the surface of the lead screw 204 and slidably connected to the inside of the adjusting frame 203; a connecting rod 206, the other end of which is connected to the top of the sliding block 205 via a rotating shaft; the other end of the connecting rod 206 is connected to the bottom of the screening frame 101 via a rotating shaft. With the cooperation of the amplitude adjustment mechanism, the position of the sliding block 205 can be adjusted according to the characteristics of the rice to adjust the shaking amplitude of the screening frame 101. When the sliding block 205 is away from the axis of the rotating disk 202, the shaking amplitude of the screening frame 101 will increase, and vice versa. A larger vibration amplitude is needed to separate larger or harder rice to improve the separation efficiency, while a smaller or softer rice may require a smaller vibration amplitude. Thus, by adjusting the shaking amplitude, the rice husk and brown rice in the rice can be better separated, reducing losses and increasing the rice yield.
[0021] like Figures 1-2As shown, sliding grooves 301 are provided on both sides of the base frame 1. Guide rods 302 are fixedly connected to the inner wall of the sliding grooves 301. Sliding members 303 are fixedly connected to both sides of the screening frame 101. The sliding members 303 are distributed and sleeved on the surface of the guide rods 302 and slidably connected to the inside of the sliding grooves 301. When the screening frame 101 shakes, the screening frame 101 can drive the sliding members 303 on both sides to slide smoothly inside the sliding grooves 301 under the guidance of the guide rods 302. Therefore, the cooperation between the sliding grooves 301 and the guide rods 302 ensures the smooth movement of the screening frame 101. When the screening frame 101 shakes, the sliding members 303 can avoid unnecessary lateral displacement through the guiding action of the guide rods 302, reduce the impact of vibration on the structure, and thus improve the stability of the entire equipment.
[0022] like Figures 1-2 As shown, a telescopic spring 4 is movably sleeved on the surface of the guide rod 302. The ends of the telescopic spring 4 are fixedly connected to the inner walls of the sliding member 303 and the sliding groove 301, respectively. The telescopic spring 4 is elastic and can provide elastic force during the movement of the sliding member 303 to enhance the amplitude. At the same time, when the sliding member 303 moves, the spring provides elastic support to prevent the sliding member 303 from excessively deviating or causing unnecessary shaking due to inertia.
[0023] like Figure 3 As shown, a knob 5 is fixedly connected to the end of the lead screw 204. The knob 5 is circular in shape. The circular knob 5 is very ergonomic when operating, and the user can easily grasp and rotate it. The position of the knob 5 can be easily adjusted, which helps to achieve precise rotation adjustment. It can achieve smooth and consistent rotation, thereby making the movement accuracy of the lead screw 204 higher and enabling more precise adjustment of the position of the slider 205.
[0024] like Figures 1-2 As shown, a baffle plate 6 is fixedly connected to the inner wall of the screening frame 101. The bottom of the baffle plate 6 is toothed. The toothed design of the bottom of the baffle plate 6 can not only effectively break the accumulation of materials during the screening process, but also help to separate the chaff from the rice, making the chaff separation effect better. At the same time, it avoids the material from stagnating or accumulating on the surface of the screening mesh 102, thereby improving screening efficiency and flowability.
[0025] like Figure 3 As shown, an extension plate 7 is fixedly connected to the bottom of the screening frame 101. The extension plate 7 is connected to the end of the connecting rod 206 through a rotating shaft. The extension plate 7 can increase the connection area and stability between the screening frame 101 and the connecting rod 206. When the screening frame 101 shakes or vibrates, it maintains good stability, avoiding a small connection area between the connecting rod 206 and the screening frame 101, and preventing uneven shaking of the screening frame 101. This improves the stability of the screening equipment and helps to improve the accuracy and effect of the screening process.
[0026] The working principle of this utility model is as follows: When screening rice, the material can first be added to the screening mesh 102 inside the screening frame 101. Then, the servo motor 201 is run, which drives the rotating disk 202 to rotate. The rotation of the rotating disk 202 drives the top adjustment frame 203 to rotate. The rotation of the adjustment frame 203 simultaneously drives the lead screw 204 and the sliding block 205 to rotate. The rotation of the sliding block 205 simultaneously drives one end of the connecting rod 206 connected to the rotating shaft to rotate around the rotating disk 202. At the same time, the other end of the connecting rod 206 drives the screening frame 101 to swing back and forth inside the base frame 1. The back and forth swinging of the screening frame 101 can screen the material inside. The screened rice will pass through the screening mesh 102 and fall to the bottom of the screening frame 101. Then, the rice is discharged from the screening frame 101 through the discharge port 104. The lighter paddy rice is sieved onto the screening screen 102 and then discharged through the discharge port 103 under the action of the inclined base frame 1. During the screening process, the position of the sliding block 205 can be adjusted to move it away from the axis of the rotating disk 202. This allows the screening frame 101 to shake more strongly via the connecting rod 206. When the sliding block 205 is closer to the axis of the rotating disk 202, the shaking amplitude of the screening frame 101 is reduced. When adjusting the position of the sliding block 205, the screw 204 can be rotated. When the screw 204 rotates, it will drive the threaded sliding block 205 to slide parallel inside the adjusting frame 203, thus quickly adjusting its position. In this way, the shaking amplitude of the screening frame 101 can be flexibly adjusted according to the position of the sliding block 205. The shaking amplitude can be optimized according to the characteristics of the paddy rice, making the separation effect more precise.
[0027] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
