Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of grain and chaff separation, and particularly relates to an intelligent gravity grain and chaff separator. BACKGROUND

[0002] The gravity grain and chaff separator is used for separating the grain and chaff by using the physical property differences of the specific gravity, particle size and friction coefficient of the grain and chaff. Under the action of the transverse reciprocating shaking separation plate, the grain and chaff mixture is gradually automatically classified, the chaff with large specific gravity and small particle size sinks, and the chaff is transported by the bidirectional inclined convex point separation plate to move obliquely upward above the separation plate and then flows out. The grain with small specific gravity and large particle size floats on the upper layer of the chaff, slides obliquely downward below the separation plate and then flows out, so that the separation according to the quality is achieved.

[0003] The rice quality analyzer is often used to detect the material separated by the gravity grain and chaff separator. The rice quality analyzer is a device for evaluating the appearance quality of rice by using advanced optical technology and image processing algorithms. The principle mainly includes four parts of light source, sensor, image processing and data analysis. The sensor is one of the core components of the rice quality analyzer. The sensor can receive the light signal reflected back by the irradiated rice sample and convert it into an electric signal. These electric signals contain the spectral information of the rice sample, which can reflect the color, transparency, texture and other characteristics of the rice.

[0004] At present, the Chinese patent with the publication number CN219084458U and the publication date of May 26, 2023 discloses an automatic sampling detection device of a rice huller and an intelligent rice huller. The automatic sampling detection device controls the sampling mechanism of the rice huller to perform the sampling action, and transports the sampled grain and chaff mixture to the rice quality analyzer through the conveying hose for analysis. Since the conveying hose is used for conveying, the damage and breakage probability of the material particle sample in the conveying process is reduced. In addition, the rice quality analyzer is arranged beside the rice huller, the sample conveying path is shortened, the time from sampling to detection is shortened, the damage and breakage probability of the material particle sample in the conveying process is further reduced, the analysis accuracy of the rice quality analyzer is improved, the intelligent adjustment effect of the rice huller is improved, and the grain loss is reduced.

[0005] The sampling device is usually installed below the outlet of the rice huller. After sampling, the sample is conveyed to the rice quality analyzer through the chute, and the data such as the shelling rate and the chaff breaking rate are communicated to the control system of each rice huller to control the processing parameters, so as to improve the processing effect of the rice huller.

[0016] The further arrangement of the present application is that the two sampling pipes are provided with electromagnetic valves.

[0017] By using the above technical scheme, when suction is generated in one sampling pipe, the electromagnetic valve of the other sampling pipe needs to be closed, so as to avoid confusion of different materials sucked in the two sampling pipes.

[0018] The further arrangement of the present application is that the material receiving groove is in a tubular shape covering the falling positions of the materials in the multiple layers of material distribution sieve plates, and the side edge of the material receiving groove is provided with a material receiving opening extending in parallel with the extension direction of the material receiving groove.

[0019] By using the above technical scheme, since the materials are all sliding down from the multiple layers of material distribution sieve plates arranged in the material distribution device, the material distribution sieve plates of different heights will fall at different positions, and the material receiving groove is in a tubular shape covering the falling positions of the materials in the multiple layers of material distribution sieve plates, so that the material receiving opening of the material receiving groove can simultaneously receive the materials sliding down from the multiple layers of material distribution sieve plates, and finally the rice quality analyzer can obtain the data of the materials sliding down from all the material distribution sieve plates.

[0020] The further arrangement of the present application is that the driving member comprises a driving shaft connected to the end of the receiving groove away from the fixed pipe, a through hole provided at the end of the guide sleeve away from the fixed pipe and through which the driving shaft passes, a rodless cylinder provided at the end of the guide sleeve away from the fixed pipe and the driving block is rotationally connected to the end of the driving shaft, and a servo motor provided on the driving block of the rodless cylinder and the output shaft is connected to the driving shaft.

[0021] By adopting the above technical scheme, when it is necessary to receive the falling material in the guide sleeve, the servo motor is first used to drive the driving shaft to rotate, so that the receiving port of the receiving groove faces upward, and then the falling material in the guide sleeve can fall into the receiving groove through the receiving port, and after the receiving is completed, the rodless cylinder is used to drive the receiving groove to pass through the connecting hole and then enter the fixed pipe, and then the suction fan is used to generate suction in the fixed pipe through the suction pipe and the sampling pipe, so that the material in the receiving groove is sucked out, and the material can be sent into the rice quality analyzer under the action of the suction force.

[0022] At the same time, when the receiving groove does not need to receive material, the servo motor is used to drive the driving shaft to rotate, so that the receiving port of the receiving groove faces downward, and at this time the falling material in the guide sleeve can no longer enter the receiving groove.

[0023] The further arrangement of the present application is that the end of the receiving groove away from the driving shaft is provided with a filter screen plate, the side of the filter screen plate away from the receiving groove is provided with a fixed shaft, the end of the fixed shaft away from the filter screen plate is wrapped with a filter screen pipe for collecting dust and impurities in the guide sleeve, the end of the filter screen pipe close to the filter screen plate is open and the end of the filter screen pipe away from the filter screen plate is closed, a dust falling gap is left between the open end of the filter screen pipe and the filter screen plate, the end of the fixed pipe away from the guide sleeve is provided with a dust discharging port through which the filter screen pipe passes, and the outer wall of the fixed pipe at the dust discharging port is provided with a cover plate hinged to the outer wall of the fixed pipe on the upper side.

[0025] When the material falling in the guide sleeve needs to be taken, first, the servo motor drives the driving shaft to rotate, so that the material receiving port of the material receiving groove faces upward, then the material falling in the guide sleeve can fall into the material receiving groove through the material receiving port, after the material receiving is completed, the rodless cylinder drives the material receiving groove to pass through the connecting hole and then enters the fixed tube; at this time, the filter screen tube can push the cover plate of the ash discharge port and move to the outside of the fixed tube, and the filter screen plate at the end of the material receiving groove can move to the position of the ash discharge port, at this time, under the action of the suction force of the extraction fan, the position of the ash discharge port can suck the air outside, then the suction force formed at the ash discharge port can act on a part of the filter screen tube, so that the dust and impurities accumulated in the filter screen tube move towards the ash discharge port side, until the dust and impurities move to the ash falling gap between the opening end of the filter screen tube and the filter screen plate, due to the blocking effect of the filter screen plate, the dust and impurities can fall at the position of the ash falling gap, and finally the dust and impurities accumulated in the filter screen tube can be emptied, so that the dust inside the material can be cleaned.

[0028] By adopting the above technical solution, when the rodless cylinder drives the material receiving groove to pass through the connecting hole and then enters the fixed tube and the filter screen tube moves to the outside of the fixed tube, the driving shaft drives the rubber disc sleeve to move towards the connecting hole side, and after the rubber disc sleeve abuts against the connecting hole, the connecting hole can be covered by the rubber disc sleeve, the air entering the fixed tube from the connecting hole can be blocked by the rubber disc sleeve, so that the suction force formed in the fixed tube is concentrated at the position of the ash discharge port, and finally the suction force at the ash discharge port can drive the dust and impurities accumulated in the filter screen tube to move towards the ash discharge port side.

[0029] The beneficial effects of the present application are: after a batch of total mixed materials falls from the feeding hopper, different materials can be discharged from the first discharge port, the second discharge port and the third discharge port through the uniform material device, the material distribution device, the reciprocating oscillation mechanism and the separation assembly; when the materials fall from the guide sleeve in the first discharge port and the third discharge port, the drive cylinder drives the partition plate to move to different positions along the connecting shaft, and when the partition plate is in different positions, the sampling assembly samples part of the materials falling in the guide sleeve to obtain multiple groups of sampled materials, then the multiple groups of sampled materials are sequentially sent into the rice quality analyzer for quality analysis, and the rice quality analyzer can obtain the quality results of each group of sampled materials, then the rice quality analyzer can select the partition plate position corresponding to the sampled material with the best quality result, and then the drive cylinder moves the partition plate to the partition plate position, finally the width range of the discharge area separated by the partition plate can be precisely controlled to ensure that the different materials discharged from the first discharge port, the second discharge port and the third discharge port are in the best state;

[0030] Then, after the second batch of total mixed materials falls from the feeding hopper, the sampling assembly samples part of the materials falling in the guide sleeve again, so that the different materials discharged from the first discharge port, the second discharge port and the third discharge port during the separation of each batch of total materials can always be in the best state;

[0031] When the sampling assembly is used, when the receiving groove does not need to receive materials, the servo motor drives the drive shaft to rotate, so that the receiving port of the receiving groove faces downward, at this time the materials falling in the guide sleeve can no longer enter the receiving groove; at the same time, the receiving groove is connected with the filter screen tube by the filter screen plate and the fixed shaft, at this time the filter screen tube is located in the fixed tube and the open end of the filter screen tube is wrapped at the position of the connecting hole, and the suction fan remains in the open state, so that the suction fan provides suction in the fixed tube towards the guide sleeve, at this time the dust and impurities generated in the guide sleeve due to the falling materials can be sucked into the filter screen tube and accumulated in the filter screen tube;

[0032] When the material falling in the guide sleeve needs to be taken, first, the servo motor drives the driving shaft to rotate, so that the material receiving port of the material receiving groove faces upward, then the material falling in the guide sleeve can fall into the material receiving groove through the material receiving port, and after the material receiving is completed, the rodless cylinder drives the material receiving groove to pass through the connecting hole and then enters the fixed tube; at this time, the filter screen tube can push the cover plate of the ash discharge port and move to the outside of the fixed tube, and the filter screen plate at the end of the material receiving groove can move to the position of the ash discharge port, at this time, under the action of the suction of the extraction fan, the position of the ash discharge port can suck the air outside, then the suction formed at the ash discharge port can act on a part of the filter screen tube, so that the dust and impurities accumulated in the filter screen tube move to the ash discharge port side, and when the dust and impurities move to the ash falling gap between the opening end of the filter screen tube and the filter screen plate, the dust and impurities can fall at the position of the ash falling gap due to the blocking action of the filter screen plate, and finally the dust and impurities accumulated in the filter screen tube can be emptied, so that the dust inside the material is cleaned.

[0033] At the same time, the suction of the extraction fan in the fixed tube extracts the material in the material receiving groove, and the material can be sent into the rice quality analyzer under the action of the suction. BRIEF DESCRIPTION OF DRAWINGS

[0049] Principle: After a batch of total mixed materials falls into the feeding hopper 4, different materials can be made to fall out of the first discharge port 63, the second discharge port 64 and the third discharge port 65 through the material uniformizing device 3, the material distributing device 2, the reciprocating oscillation mechanism 5 and the separation assembly 6; wherein when the materials fall out of the first discharge port 63 and the third discharge port 65 through the guide sleeve 8, the separation plate 62 is moved to different positions along the connecting shaft 611 by the driving cylinder 612, and when the separation plate 62 is at different positions, part of the materials falling in the guide sleeve 8 are sampled by the sampling assembly 9 to obtain multiple groups of sampled materials, and then the multiple groups of sampled materials are sequentially sent into the rice quality analyzer 7 for quality analysis, and the rice quality analyzer 7 can obtain the quality results of each group of sampled materials, and then the rice quality analyzer 7 can select the position of the separation plate 62 corresponding to the sampled material with the best quality result, and then the driving cylinder 612 is used to move the separation plate 62 to the position of the separation plate 62, so as to finally realize fine control of the width range of the separation area of the separation plate 62, so as to ensure that the different materials discharged from the first discharge port 63, the second discharge port 64 and the third discharge port 65 are in the best state;

[0050] Then, after the second batch of total mixed materials falls into the feeding hopper 4, part of the materials falling in the guide sleeve 8 are again sampled by the sampling assembly 9, so that the different materials discharged from the first discharge port 63, the second discharge port 64 and the third discharge port 65 can always be in the best state during the separation of each batch of total materials;

[0051] In the use of the sampling assembly 9, when the receiving trough 95 does not need to receive materials, the servo motor 974 drives the driving shaft 971 to rotate, so that the receiving port 951 of the receiving trough 95 faces downward, and the falling materials in the guide sleeve 8 cannot enter the receiving trough 95. At the same time, the receiving trough 95 is connected with the filter screen tube 954 through the filter screen plate 952 and the fixed shaft 953. At this time, the filter screen tube 954 is located in the fixed tube 94, and the open end of the filter screen tube 954 is wrapped around the connecting hole 96. The suction fan 91 is kept in an open state, so that the suction fan 91 provides suction in the fixed tube 94 to suck air from the guide sleeve 8, and the dust and impurities generated by the falling materials in the guide sleeve 8 are sucked into the filter screen tube 954 and accumulated in the filter screen tube 954.

[0052] When the falling materials in the guide sleeve 8 need to be received, the servo motor 974 drives the driving shaft 971 to rotate, so that the receiving port 951 of the receiving trough 95 faces upward, and then the falling materials in the guide sleeve 8 fall into the receiving trough 95 through the receiving port 951. After the receiving is completed, the rodless cylinder 973 drives the receiving trough 95 to pass through the connecting hole 96 and enter the fixed tube 94 through the driving shaft 971. At this time, the filter screen tube 954 can push the cover plate 942 of the dust outlet 941 and move to the outside of the fixed tube 94, and the filter screen plate 952 at the end of the receiving trough 95 can move to the position of the dust outlet 941. At this time, under the action of the suction of the suction fan 91, the position of the dust outlet 941 can suck air from the outside, and then the suction formed at the dust outlet 941 can act on a part of the filter screen tube 954, so that the dust and impurities accumulated in the filter screen tube 954 move towards the dust outlet 941. When the dust and impurities move to the dust falling gap between the open end of the filter screen tube 954 and the filter screen plate 952, they can fall at the position of the dust falling gap due to the blocking action of the filter screen plate 952, and finally the dust and impurities accumulated in the filter screen tube 954 can be emptied, so that the dust inside the materials can be cleaned.

[0053] At the same time, the suction fan 91 generates suction in the fixed tube 94 to suck the materials in the receiving trough 95, and the materials can be sent into the rice quality analyzer 7 under the action of the suction.
