AI Technical Summary
During the tubular chain conveying process, rice is prone to getting stuck in the gap between the chain and the pipe, causing cross-contamination. This results in insufficiently processed rice grains entering the next process, affecting the quality and safety of the rice.
The conveying pipeline is divided into a conveying section for process x and a conveying section for process y, with a material discharge port set between the two. The material discharge port faces downward, and the rice grains are made to enter the receiving tray by gravity, so as to avoid the grains being stuck and entering the next process. At the same time, a pipe chain drive and tensioning device are set on the pipeline to ensure stable conveying.
This effectively prevents rice grains from getting stuck during transportation, ensuring that rice grains at each stage are fully processed, improving the quality and safety of rice processing, and preventing insufficiently processed rice from entering the next stage.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rice processing technology, specifically relating to an anti-cross-contamination conveying device for rice processing. Background Technology
[0002] The tubular chain conveyor used in rice processing is a specialized device for continuous conveying. It consists of a closed pipe with a drive chain or chain links inside, which propels the material along the inner wall of the pipe. This equipment has advantages such as compact structure, small footprint, and stable conveying, making it particularly suitable for conveying materials in a closed, dust-free environment.
[0003] During the conveying process, rice enters the pipe through the inlet and is propelled forward along the inner wall of the pipe by the chain or chain links, eventually being discharged from the outlet. As the material moves within the pipe, it is subjected to the thrust of the chain and the friction between the material layers, forming a stable material flow. Because the pipeline is enclosed, it can effectively prevent dust from flying and reduce environmental pollution. However, during the operation of the circulating tubular chain machine in the mobile processing center, rice needs to complete multiple processes of rice conveying and feeding to subsequent processing stages. In each process, the processing precision and post-processing state of the rice within the tubular chain vary. The conveying of rice relies entirely on the pulling of the chain. During the process of the chain pulling in the pipeline, rice grains are prone to get stuck in the gap between the chain and the pipeline, forming cross-contamination. This affects the processing precision and subsequent state of the material within the tubular chain, causing unprocessed rice to directly enter the next process. As a result, these rice grains do not undergo sufficient processing in each stage and flow into the final stage, or even leave the factory for sale. These unprocessed rice grains may contain impurities and fertilizer residues, which not only affect the appearance and taste but also pose safety risks, seriously affecting the quality of the rice and having adverse effects. Utility Model Content
[0004] The purpose of this invention is to provide a rice processing anti-cross-contamination conveying device, which aims to solve the above-mentioned problems existing in the prior art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A rice processing anti-cross-contamination conveying device includes a conveying pipe installed on a tubular chain conveyor. The conveying pipe is divided into an x-process conveying section and a y-process conveying section. The x-process conveying section is provided with an x-process inlet and an x-process outlet. The x-process outlet is connected to the next process equipment via a pipe.
[0007] The conveying section of process Y is provided with a feed inlet and a discharge outlet for process Y. The discharge outlet for process Y is connected to the equipment of the next process via a pipeline.
[0008] The conveying pipe (1) set on the tubular chain conveyor can be set with multiple process conveying sections. The x process conveying section (11) and the y process conveying section (12) are both implemented in the conveying pipe (1) on the tubular chain conveyor.
[0009] A material discharge port is also provided on the conveying pipeline between the x-process conveying section and the y-process conveying section;
[0010] The conveying pipeline is equipped with a pipe chain scraper and a chain.
[0011] In a preferred embodiment of this utility model, the conveying pipe is provided with a pipe chain drive device and a pipe chain tensioning device, and the rice grains are conveyed in the conveying pipe by the pipe chain drive device and the pipe chain tensioning device.
[0012] In a preferred embodiment of this utility model, a receiving tray is placed below the material discharge port.
[0013] In a preferred embodiment of this utility model, the opening of the material discharge port faces downward.
[0014] In a preferred embodiment of this utility model, a residual material discharge port is also provided at the end of the conveying pipeline that is away from the x-process conveying section and the y-process conveying section.
[0015] In a preferred embodiment of this utility model, the material discharge port and the residual material discharge port are staggered.
[0016] In a preferred embodiment of this utility model, the conveying pipeline is provided with a plurality of x-process conveying sections and y-process conveying sections, and at least one material discharge port is provided between each x-process conveying section and each y-process conveying section.
[0017] In a preferred embodiment of this utility model, the conveying pipeline is used for cyclic conveying through the pipe chain drive device, the pipe chain tensioning device, and the pipe chain scraper and chain inside the conveying pipeline.
[0018] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:
[0019] This utility model relates to an anti-cross-contamination conveying device for rice processing. To prevent rice grains from accumulating in the gap between the chain and the pipe in the conveying pipeline, thus preventing cross-contamination, the conveying pipeline is divided into two sections: a process X conveying section and a process Y conveying section. Rice grains from process X enter the process X conveying section through the process X inlet and are then conveyed to the process X outlet by the chain conveyor under normal transport. The rice grains that are accumulating or cross-contaminating in the pipeline continue to be transported as the chain conveyor operates. Upon reaching the cross-contamination outlet, because the outlet opening faces downwards, the rice grains fall into the receiving tray below the outlet under their own gravity. This prevents the accumulating or cross-contaminating rice grains from directly flowing into the process Y conveying section, thus preventing cross-contamination during the rice grain transport process. This avoids rice grains not fully passing through each processing stage and flowing into the final stage, or even being sold after processing, affecting appearance and taste, and improving the processing quality and safety of rice grains.

Detailed Implementation
[0024] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model.

It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.
[0025] Example:
[0026] like Figure 1-3As shown, this embodiment provides a rice processing anti-cross-contamination conveying device, including a conveying pipe 1 installed on a tubular chain conveyor. The conveying pipe 1 is divided into an x-process conveying section 11 and a y-process conveying section 12. The x-process conveying section 11 is provided with an x-process inlet 2 and an x-process outlet 3. The x-process outlet 3 is connected to the next process equipment via a pipe.
[0027] The conveying section 12 of process y is provided with a process y inlet 10 and a process y outlet 6. The process y outlet 6 is connected to the equipment of the next process through a pipeline.
[0028] The conveying pipe 1 installed on the tubular chain conveyor can be set up with multiple process conveying sections, such as process x conveying section 11 and process y conveying section 12, which are both implemented in the conveying pipe 1 on the tubular chain conveyor.
[0029] A material discharge port 4 is also provided on the conveying pipeline 1 between the x-process conveying section 11 and the y-process conveying section 12;
[0030] The conveying pipeline 1 is equipped with a pipe chain scraper and chain.
[0031] In a specific application scenario, to prevent rice grains in the conveying pipe 1 from becoming stuck in the gap between the chain and the pipe, thus causing cross-contamination, the conveying pipe 1 is divided into two sections: the x-process conveying section 11 and the y-process conveying section 12. Rice grains from the x-process enter the x-process conveying section 11 through the x-process inlet 2 and are then conveyed to the x-process outlet 3 by the chain conveyor, where they are connected to the next process equipment via a pipe. At this point, rice grains stuck or cross-contaminated in the conveying pipe 1 continue to be conveyed as the chain conveyor operates. When they pass the cross-contamination outlet 4, because the outlet 4 faces downwards, the rice grains fall into the receiving tray 5 below it due to their own gravity, thus blocking the path of stuck or cross-contaminated rice grains directly into the y-process conveying section 12 and preventing cross-contamination during the rice grain conveying process. The following description, in conjunction with this application scenario, further illustrates the anti-cross-contamination conveying device for rice processing of this utility model.
[0032] Furthermore, referring to Figure 1-3 The conveying pipeline 1 is equipped with a pipe chain drive device 7 and a pipe chain tensioning device 8, and the rice grains are conveyed in the conveying pipeline 1 by the pipe chain drive device 7 and the pipe chain tensioning device 8.
[0033] In this embodiment, in order to maintain the stability of rice grains during the conveying process, a pipe chain drive device 7 and a pipe chain tensioning device 8 are installed on the conveying pipe 1 for driving, thereby cooperating with the pipe chain scraper and chain provided in the conveying pipe 1 to achieve the function of conveying rice grains.
[0034] In more detail, refer to Figure 1-3 A receiving tray 5 is placed below the material outlet 4.
[0035] In this embodiment, since the rice grains that are stuck or mixed with other materials are only caused by poor transportation during the transportation process and do not have any quality problems, they cannot be discarded just because of the mixing. In order to collect the rice grains that are stuck or mixed with other materials in the conveying pipe 1, a receiving tray 5 is placed below the mixing outlet 4 to receive them, so as to avoid the waste and pollution caused by the rice grains falling directly.
[0036] More preferably, refer to Figure 1-3 The opening of the material discharge port 4 faces downwards.
[0037] In this embodiment, in order to facilitate the timely discharge of rice grains that are stuck or mixed with other materials from the conveying pipe 1, the openings of the material discharge port 4 and the residual material discharge port 9 are set to face downwards. As a result, when the rice grains that are stuck or mixed with other materials pass through the material discharge port 4, they fall from the material discharge port 4 due to their own gravity, thereby separating them from the conveying pipe 1 and preventing them from being mixed into the next process.
[0038] More preferably, refer to Figure 1-3 The end of the conveying pipeline 1 that is away from the conveying section 11 of process x and the conveying section 12 of process y is also provided with a residual material discharge port 9.
[0039] In this embodiment, after the rice grains pass through the x-process conveying section 11 and the y-process conveying section 12, some residual material will inevitably remain. In order to collect and process the residual material in a unified manner, a residual material discharge outlet 9 is provided after the x-process conveying section 11 and the y-process conveying section 12 on the conveying pipeline 1 to discharge the residual material and prevent it from being mixed into the normal rice grains.
[0040] Furthermore, referring to Figure 1-3 The material discharge port 4 and the residual material discharge port 9 are staggered.
[0041] In this embodiment, in order to avoid mixing of the rice grains discharged from the discharge port 4 with the residual grains discharged from the residual discharge port 9 during the rice grain conveying process, the discharge port 4 and the residual discharge port 9 are staggered to maintain their independence.
[0042] Furthermore, referring to Figure 1-3 The conveying pipeline 1 is divided into several x-process conveying sections 11 and y-process conveying sections 12, and at least one material outlet 4 is provided between each x-process conveying section 11 and y-process conveying section 12.
[0043] In this embodiment, several x-process conveying sections 11 and y-process conveying sections 12 are set on the conveying pipeline 1 to adapt to multiple processes in the rice processing flow. At the same time, at least one series of material outlets 4 are set between each x-process conveying section 11 and y-process conveying section 12 for matching use, thereby improving the applicability.
[0044] More specifically, refer to Figure 1-3 The conveying pipeline 1 is circulated and conveyed by the pipe chain drive device 7, the pipe chain tensioning device 8, and the pipe chain scraper and chain inside the conveying pipeline 1.
[0045] In this embodiment, during the conveying of rice grains, the length of the conveying pipe 1 cannot be extended indefinitely, and for the purpose of recycling, the rice grains need to be conveyed in a cyclic manner. Therefore, the conveying pipe 1 is set to be cyclically conveyed by the pipe chain drive device 7, the pipe chain tensioning device 8, and the pipe chain scraper and chain inside the conveying pipe 1.
[0046] Working principle:
[0047] The present invention relates to a rice processing anti-cross-contamination conveying device. After rice grains enter the conveying pipe 1, the pipe chain scraper and chain in the conveying pipe 1 slide under the drive of the pipe chain drive device 7 and the pipe chain tensioning device 8, thereby driving the rice grains to be conveyed synchronously in the conveying pipe 1.
[0048] To prevent rice grains from getting stuck in the gap between the chain and the pipe in conveying pipe 1, causing cross-contamination, conveying pipe 1 is divided into two sections: process x conveying section 11 and process y conveying section 12. Rice grains from process x enter process x conveying section 11 through process x inlet 2, and are then conveyed to process x outlet 3 by the chain conveyor under normal transport conditions, and then connected to the next process equipment via a pipe. At this point, rice grains stuck in conveying pipe 1 and cross-contaminated will continue to be transported as the chain conveyor operates, causing cross-contamination. At discharge port 4, since the opening of discharge port 4 faces downward, rice grains will fall into the receiving tray 5 set below discharge port 4 under their own gravity, thereby blocking the path of the stuck and cross-contaminated rice grains directly into the conveying section 12 of process y, and preventing cross-contamination of rice grains during the conveying process; similarly, the rice grains conveyed in the conveying section 12 of process y will also enter from the inlet 10 of process y and enter the next process through the outlet 6 of process y, while the residual material is discharged through the residual material outlet 9, maintaining the integrity and independence between the processing processes of rice grains.
[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
