Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice processing technology, and in particular to a gravity rice-brown rice separator. Background Technology
[0002] During the refining process of rice, the grains and husks need to be further cleaned. Gravity grain separators are often used to separate the grains and husks. The principle is to use gravity and friction to separate the materials. It is widely used in the screening of various particulate materials.
[0003] In existing technologies, rice is usually added directly through a rice feeding hopper to a gravity rice separator, and then separated through an internal sieve plate. In this method, the rice is added in a fixed position, meaning the area added to the sieve plate is limited, which prevents the rice from being added evenly. Furthermore, rice tends to accumulate during the separation process, reducing the separation efficiency. Therefore, it is necessary to design a gravity rice separator to solve the above problems.
[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0032] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0033] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a gravity rice-brown rice separator, comprising:
[0034] Gravity rice separator 1 is equipped with a uniform adding mechanism. It should be noted that the uniform adding mechanism can uniformly add rice to the sieve plate 2, which can effectively reduce the accumulation of rice during sieving, fully sieve the rice, and improve the separation effect.
[0035] The uniform addition mechanism includes a discharge pipe 3, a cylinder 4, a power motor 6, a turntable 7, a rotating shaft 9, a reciprocating screw 10, a reciprocating screw assembly 11, a transfer box 12, and a diversion pipe 13;
[0036] The discharge pipe 3 is fixedly installed on the gravity rice separator body 1 and the cylinder 4. The power motor 6 is fixedly installed on the cylinder 4. The output end of the power motor 6 is fixedly connected to the turntable 7. The turntable 7 has a rice storage chamber 8. The rotating shaft 9 is fixedly installed between the turntable 7 and the reciprocating screw 10. The reciprocating screw assembly 11 is threadedly connected to the reciprocating screw 10. It should be noted that the reciprocating screw 10 drives the reciprocating screw assembly 11 to move laterally and reciprocally through the reciprocating spiral groove on the outer wall. This is the prior art and will not be described in detail here.
[0037] The reciprocating screw assembly 11 is fixedly connected to the transfer box 12, and the diversion pipe 13 is fixedly installed at the bottom of the transfer box 12.
[0038] Through the aforementioned uniform addition mechanism, starting the power motor 6 causes the turntable 7 to rotate, driving the rice storage chamber 8 on the turntable 7 to rotate. When the rice storage chamber 8 is connected to the rice adding hopper 5, rice enters the rice storage chamber 8. After the rice storage chamber 8 rotates and connects to the discharge pipe 3, the rice in the rice storage chamber 8 can be discharged from the discharge pipe 3 into the transfer box 12. This allows for intermittent feeding of rice, avoiding accumulation caused by excessive feeding. The turntable 7 drives the reciprocating screw 10 to rotate through the rotating shaft 9, which in turn causes the reciprocating screw assembly 11 to drive the transfer box 12 to move back and forth in the front and back directions. This allows the diversion pipe 13 to move back and forth in the front and back directions, and the rice in the transfer box 12 is discharged from multiple diversion pipes 13. This allows for uniform addition of rice to the sieve plate 2 for screening, effectively reducing the accumulation of rice during screening, fully screening the rice, and improving the separation effect.
[0039] Specifically, the uniform addition mechanism also includes a rice adding hopper 5, which is fixedly installed on the cylinder 4 and is connected to the inside of the cylinder 4.
[0040] The above-mentioned uniform addition mechanism makes it easy to add rice.
[0041] Specifically, the turntable 7 is in sealed contact with the inside of the cylinder 4, the discharge pipe 3 is connected to the inside of the cylinder 4, and the discharge pipe 3 is connected to the inside of the gravity rice separator 1. The discharge pipe 3 is located directly above the transfer box 12. It should be noted that this facilitates the rice to enter the transfer box 12 through the discharge pipe 3.
[0042] Specifically, there are multiple diversion pipes 13, and the multiple diversion pipes 13 are equally spaced. The diversion pipes 13 are connected to the inside of the transfer box 12. It should be noted that this facilitates the diversion of rice in the transfer box 12.
[0043] Specifically, a movable hole is provided on the rear side of the gravity grain separator body 1, and the reciprocating screw assembly 11 is slidably installed in the movable hole. The rotating shaft 9 is rotatably installed on the cylinder 4. It should be noted that this allows the reciprocating screw assembly 11 to move stably in the front and back directions.
[0044] Specifically, a sieve plate 2 is installed inside the gravity rice separator 1, and a vibrator is installed at the bottom of the sieve plate 2. The gravity rice separator 1 has discharge port 14 and discharge port 25 on its two sides respectively. It should be noted that this facilitates the screening of rice. The screened rice is discharged through discharge port 14, and the screened impurities are discharged through discharge port 25.
[0045] Working principle:
[0046] S1: Start the power motor 6. The output of the power motor 6 drives the turntable 7 to rotate. The turntable 7 has a rice storage chamber 8. When the rice storage chamber 8 rotates to connect with the rice adding hopper 5, rice enters the rice storage chamber 8. As the turntable 7 continues to rotate, when the rice storage chamber 8 rotates and connects with the discharge pipe 3, the rice in the rice storage chamber 8 is discharged from the discharge pipe 3 into the transfer box 12, thereby realizing the intermittent feeding of rice and avoiding the accumulation phenomenon caused by feeding too quickly.
[0047] S2: When the turntable 7 rotates, the reciprocating screw 10 is driven to rotate through the rotating shaft 9. Because the reciprocating screw assembly 11 is threadedly connected to the reciprocating screw 10, the reciprocating screw 10 drives the reciprocating screw assembly 11 to move laterally through the reciprocating spiral groove on the outer wall. This causes the reciprocating screw assembly 11 to drive the transfer box 12 to move back and forth in the front and back directions. The multiple diversion pipes 13 at the bottom of the transfer box 12 also move back and forth in the front and back directions. The rice in the transfer box 12 is discharged from the multiple diversion pipes 13 that are equally spaced and connected to the inside of the transfer box 12, and is evenly added to the sieve plate 2, effectively reducing the accumulation of rice during sieving.
[0048] S3: The vibrator installed at the bottom of the sieve plate 2 works, causing the sieve plate 2 to vibrate, and the rice evenly distributed on the sieve plate 2 is screened and separated. Gravity and friction are used to separate the grains from impurities such as husks.
[0049] The above provides a detailed description of a gravity-fed rice separator for processing rice according to this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core idea of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
