Description

Technical Field

[0001] This invention belongs to the field of rice-coarse separation technology, and particularly relates to a lifting device for a rice-coarse separation screen. Background Technology

[0002] Paddy-brown rice separation is a core process in paddy processing that utilizes the differences in physical properties between paddy rice and brown rice, such as specific gravity, particle size, and coefficient of friction, to grade the mixture using mechanical devices. This process employs a horizontally reciprocating separating plate or vibrating screen. Brown rice sinks and is then conveyed upwards by a bi-directionally inclined separating plate with raised points, while paddy rice floats and slides downwards. The separated paddy rice is returned to the hulling machine for secondary processing, while the brown rice enters the milling process. The process requires that the brown rice content be controlled below 40 grains / kg, and the brown rice content in the returned hulled paddy rice should not exceed 10%. This process directly affects milling precision and production efficiency. Incomplete separation will lead to increased equipment energy consumption, damage to brown rice, and dust and noise pollution.

[0003] In existing rice-hulling separation screens, the separated rice needs to be transported back to the rice huller for secondary processing using a lifting device. The mechanisms involved in the processing are relatively complex, which not only increases manufacturing and maintenance costs but also reduces the efficiency of rice processing. To avoid the above situation, a lifting device for rice-hulling separation screens is provided. Summary of the Invention

[0014] Compared with the prior art, the embodiments of this application have the following main advantages: By combining and using a separation and lifting mechanism and a separation and lifting motor, the core contribution of these two mechanisms lies in integrating the two major functions of "rice-hulling separation" and "rice lifting" into the same transmission system. This achieves an integrated structural design, directly solving the problems of separate equipment and redundant mechanisms in the prior art. This design eliminates the need for an additional independent bucket elevator or screw conveyor, reducing the equipment footprint and transmission nodes, and lowering manufacturing and maintenance costs. Simultaneously, the rice is at a high position after separation, facilitating direct return to the rice huller for secondary processing, shortening the material transfer path, and improving processing continuity and efficiency. By combining and using a separation and lifting mechanism, a separation and lifting motor, a sample inspection mechanism, a sampling mechanism, and identification blocks, this combination not only achieves integrated separation and lifting but also integrates online automatic sampling and quality inspection functions, forming a closed-loop system of "separation-lifting-inspection". This significantly improves the automation level and quality control capabilities of the processing. This closed-loop feedback mechanism effectively ensures separation accuracy, prevents defective products from flowing into subsequent rice milling processes, and reduces energy consumption and the risk of rice grain damage. The base mechanism, through its adjustable reciprocating motion, adds auxiliary screening excitation to the entire separation and lifting process, enhancing the stratification effect of materials on the metal separation mesh and improving separation purity and adaptability. Compared to solutions relying solely on gravity and transmission vibration, this design significantly improves separation efficiency and purity. Furthermore, operators can flexibly adjust the frequency and amplitude of the reciprocating motion according to rice variety, moisture content, or processing speed, enhancing the equipment's adaptability to different materials. This motion mechanism is integrated within the base, eliminating the need for complex external structures, simplifying maintenance, and further solidifying the overall compactness and reliability of the device.

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] This invention provides a lifting device for a rice bran separator, including a base mechanism 1: a separation lifting mechanism 2 is provided at the upper end of the base mechanism 1, a separation lifting motor 5 is fixedly connected to the outer wall of the base mechanism 1, a sample sampling mechanism 3 is fixedly connected to the outer wall of the base mechanism 1, a sampling mechanism 4 is provided on the inner wall of the separation lifting mechanism 2, and an identification block 6 is fixedly connected to the outer wall of the separation lifting mechanism 2. The separation and lifting mechanism 2 includes a separation and lifting drive assembly 202 disposed on the base mechanism 1, and a metal separation mesh assembly 201 is disposed on the outer wall of the separation and lifting drive assembly 202. The separation lifting drive assembly 202 includes a drive shaft 2021, a linkage chain condition 2022 is engaged with the outer wall of the drive shaft 2021, and an inner belt component 2023 is attached to the outer wall of the linkage chain condition 2022.

[0020] The linkage condition 2022 includes multiple link shafts 20223. Both ends of the link shaft 20223 are connected to link blocks 20222. One end of the link shaft 20223 is fixedly connected to a first side bracket 20221. The end of the link shaft 20223 away from the first side bracket 20221 is fixedly connected to a second side bracket 20224. The second side bracket 20224 is fixedly connected to the connecting shaft 20223 by bolts, and the outer walls of the first side bracket 20221 and the second side bracket 20224 are both provided with mesh slots. The second side bracket 20224 is connected to the connecting shaft 20223 by bolts so that the second side bracket 20224 can be disassembled and the metal separation mesh 2011 can be replaced as needed. The inner belt component 2023 includes a belt 20231 adhered to the outer wall of the connecting block 20222. A notch 20232 is provided on one side of the belt 20231, and a thin layer 20233 is correspondingly provided on one side of the belt 20231. A separate lifting motor 5 is used for starting and control. Figure 1 As shown, the drive shaft 2021 rotates to the upper right, which in turn drives the linkage 2022, inner belt 2023, and metal separation mesh assembly 201 to rotate to the upper right as well. When the pre-processed paddy is poured onto the metal separation mesh 2011, under the influence of gravity and the vibration generated by the operation of the machine, the processed brown rice, which is smaller in volume but denser than paddy, will pass through the metal separation mesh 2011 and finally fall onto the belt 20231. Because the surface of the belt 20231 is smooth, the brown rice slides down, while the paddy falls onto the metal separation mesh 2011 and is blocked by the baffle 2012. It then moves up with the metal separation mesh 2011, thus separating the paddy and brown rice. At this time, the position of the paddy is also raised. The paddy in the upper position can be transferred to the rice huller for further processing as needed. The outer walls on both sides of the belt 20231 are raised to collect brown rice. The notch 20232 and the thin layer 20233 are both located on the raised sides of the belt 20231. The thickness of the raised part of the belt 20231 with the thin layer 20233 is half the thickness of other parts at the same location.

[0021] The drive shaft component 2021 includes a central shaft 20211, a plurality of limiting baffles 20212 are fixedly connected to the outer wall of the central shaft 20211, and a linkage gear 20213 is fixedly connected to the outer wall of the central shaft 20211. Among them, the linkage gear 20213 and multiple link shafts 20223 are meshed together, and two adjacent limit baffles 20212 form a limit groove that cooperates with the link block 20222.

[0022] The metal separation mesh assembly 201 includes a metal separation mesh 2011 inserted into the inner wall of the first side bracket 20221 and the second side bracket 20224, and a baffle member 2012 is inserted into the outer wall of the metal separation mesh 2011. The baffle component 2012 includes a plastic baffle 20121, the bottom of which has a card slot 20122, and the plastic baffle 20121 and the metal separation mesh 2011 are connected by the card slot 20122.

[0023] It should be noted that, due to the existing system where the separated paddy rice is transported back to the huller for secondary processing after screening, the process involves a lifting device, which is quite complex. This not only increases manufacturing and maintenance costs but also reduces the efficiency of paddy rice processing.

[0024] Specifically, in this embodiment, the solution mainly utilizes the base mechanism 1, the separation and lifting mechanism 2, the separation and lifting motor 5, the sample sampling mechanism 3, the sampling mechanism 4, and the identification marker 6 in a coordinated manner. In use, the device is first installed below the rice output end of the rice huller. The separation and lifting motor 5 is then started and controlled. Figure 1 As shown, the drive shaft 2021 rotates to the upper right, which in turn drives the linkage 2022, inner belt 2023, and metal separation mesh assembly 201 to rotate to the upper right as well. When the pre-processed paddy is poured onto the metal separation mesh 2011, under the influence of gravity and the vibration generated by the operation of the machine, the processed brown rice, which is smaller in volume but denser than paddy, will pass through the metal separation mesh 2011 and finally fall onto the belt 20231. Because the surface of the belt 20231 is smooth, the brown rice slides down, while the paddy falls onto the metal separation mesh 2011 and is blocked by the baffle 2012. It then moves up with the metal separation mesh 2011, thus separating the paddy and brown rice. At this time, the position of the paddy is also raised. The paddy in the upper position can be transferred to the rice huller for further processing as needed. When the monitoring probe 303 detects the position of the identification block 6, the separation lifting motor 5 is controlled to rotate slowly or pause so that the sampling mechanism 4 can take a sample and send it to the sampling component 307. The first telescopic hydraulic cylinder 401 is activated and controlled to move the inner sliding frame 402 and the sampling component 403 in the direction of the thin layer 20233 on the upper surface of the belt 20231. Simultaneously, the second telescopic hydraulic cylinder 40311 is activated and controlled to move the sampler 4035 to collect the brown rice on the belt 20231. Because the front end of the inner sliding frame 402 is tilted upwards, and the outer wall of the short sliding shaft 4036 is slidably connected to the inner wall of the inner sliding frame 402, the position of the sampler 4035 is also... As it rises, when it reaches the maximum height limit, the electronic lock 40334 releases the lock on the connecting plate 4034, and starts and controls the use of the ejection hydraulic cylinder 40333 to slightly lift the connecting plate 4034. The sampler 4035 rotates outward along the short sliding shaft 4036 as the rotation axis. At the same time, the first telescopic hydraulic cylinder 401 continues to move the inner sliding frame 402 and ejects the thin layer 20233 through the inner sliding frame 402, thereby realizing the pouring of the brown rice collected in the sampler 4035 into the sampling component 307. The starting and control system uses the push-and-retract hydraulic cylinder 3071 to push the inner limit slide 3072 along the inner wall of the external connecting slot 306. After the sampling mechanism 4 samples brown rice and sends it to the sampling slot 30741, the starting and control system uses the push-leveling hydraulic cylinder 30743 to move the push plate 30744. The push plate 30744 pushes the excess brown rice in the sampling slot 30741 to the auxiliary slot 30742. The mass of the brown rice is weighed by the electronic scale 3073, and the density of the brown rice is calculated based on the mass and unit volume. This determines whether the amount of paddy rice in the brown rice is within the acceptable range. If it meets the standard, the device continues to work. If it does not meet the standard, the machine is stopped and a suitable metal separating screen 2011 is replaced or the device is repaired.

[0025] In this embodiment, the drive shaft 2021 is rotated by the separation lifting motor 5, which drives the linkage condition 2022, the inner belt component 2023, and the metal separation mesh assembly 201 to move synchronously to the upper right. The rice mixture is separated into layers on the metal separation mesh 2011 by gravity and mechanical vibration: the brown rice, due to its small volume and high density, passes through the mesh and falls onto the smooth belt 20231 and slides down, while the paddy rice is blocked by the baffle component 2012 and is conveyed upward with the metal separation mesh 2011, directly completing the position lifting.

[0026] In a further preferred embodiment of the present invention, the sampling mechanism 4 includes a first telescopic hydraulic cylinder 401 fixedly connected to a first side bracket 20221. An inner sliding frame 402 is fixedly connected to the telescopic end of the first telescopic hydraulic cylinder 401, and a sampling component 403 is provided on one side of the inner sliding frame 402. The first telescopic hydraulic cylinder 401 is activated and controlled to move the inner sliding frame 402 and the sampling component 403 from the surface of the belt 20231 towards the thin layer 20233 of the belt 20231. Simultaneously, the second telescopic hydraulic cylinder 40311 is activated and controlled to move the sampler 4035 to collect the brown rice on the belt 20231. The front end of sampler 4035 is raised, and the outer wall of short sliding shaft 4036 is slidably connected to the inner wall of inner sliding frame 402. The position of sampler 4035 is also raised accordingly. When the maximum height is reached, electronic lock 40334 releases the lock on connecting plate 4034, and starts and controls the ejection hydraulic cylinder 40333 to slightly lift connecting plate 4034. Sampler 4035 rotates outward along short sliding shaft 4036 as the rotation axis. At the same time, first telescopic hydraulic cylinder 401 continues to move inner sliding frame 402 and ejects thin layer 20233 through inner sliding frame 402, thereby realizing the pouring of brown rice collected in sampler 4035 into sampling component 307. Among them, such as Figure 6As shown, the front end of the inner sliding frame 402 is raised so as to touch the thin layer 20233, and the outer wall of the first telescopic hydraulic cylinder 401 is tightly fitted with the notch 20232 in the belt 20231. The sampling assembly 403 includes a pusher connector 4031 fixedly connected to one side of the inner sliding frame 402. One end of the pusher connector 4031 is connected to a limit connector 4032. A connector 4033 is fixedly connected to the outer wall of the limit connector 4032. A connector plate 4034 is inserted into the inner wall of the connector 4033. A sampler 4035 is fixedly connected to the outer wall of the connector plate 4034. Short sliding shafts 4036 are fixedly connected to both sides of the sampler 4035. The outer wall of the short sliding shafts 4036 is slidably connected to the inner wall of the inner sliding frame 402. The pusher connector 4031 includes a second telescopic hydraulic cylinder 40311 fixedly connected to one side of the inner sliding frame 402. The telescopic end of the second telescopic hydraulic cylinder 40311 is fixedly connected to a limit connecting slider 40312. The upper and lower ends of the limit connecting slider 40312 are both fixedly connected to magnetorheological fluid packs 40313. The connecting seat 4033 includes a seat body 40331 fixedly connected to the limiting connecting seat 4032. The top of the seat body 40331 is provided with a slot 40332. An electronic lock 40334 is fixedly connected to the outer wall of one end of the seat body 40331. An ejection hydraulic cylinder 40333 is fixedly connected to the outer wall of the seat body 40331. One side of the connecting plate 4034 has a lock hole, which is used in conjunction with the electronic lock 40334. Under normal conditions, the electronic lock 40334 is fixedly connected to the connecting plate 4034 through the lock hole. The inner wall of the limiting connecting seat 4032 is provided with a vertical sliding groove. The limiting connecting slider 40312 and the magnetorheological fluid pack 40313 are both set on the inner wall of the vertical sliding groove. The limiting connecting slider 40312 is fitted and slidably connected with the inner wall of the vertical sliding groove. The outer wall of the limiting connecting seat 4032 is provided with an electromagnetic block 4037 that works in conjunction with the magnetorheological fluid pack 40313. Among them, the outer cladding layer of magnetorheological fluid package 40313 is provided with anti-slip protrusions; During the operation of the second telescopic hydraulic cylinder 40311, when the limiting connecting seat 4032, connecting seat 4033, and connecting insert 4034 are slightly raised along with the sampler 4035, the relative positional relationship between the limiting connecting seat 4032 and the limiting connecting slider 40312 also changes. When the sampler 4035 moves to the highest position, the electromagnetic block 4037 is activated, and a magnetic field is quickly formed around the magnetorheological fluid package 40313. The magnetorheological fluid package 40313 hardens, and the lower magnetorheological fluid package 40313 comes into close contact with the vertical sliding groove in the limiting connecting seat 4032, forming a fixed connection.

[0027] The sample sampling mechanism 3 includes a first external connecting seat 301 fixedly connected to the outer wall of the base mechanism 1, a second external connecting seat 302 fixedly connected to the outer wall of the first external connecting seat 301, a third external connecting seat 304 fixedly connected to the outer wall of the second external connecting seat 302, a monitoring probe 303 fixedly connected to one side of the second external connecting seat 302, a lifting hydraulic cylinder 305 fixedly connected to the outer wall of the third external connecting seat 304, an external connecting slot 306 fixedly connected to the telescopic end of the lifting hydraulic cylinder 305, and a sampling component 307 provided on the inner wall of the external connecting slot 306. The monitoring probe 303 and the identification block 6 are used together. During use, the position of the monitoring probe 303 remains fixed, while the identification block 6 moves with the separation and lifting mechanism 2. When the monitoring probe 303 detects the position of the identification block 6, the separation and lifting motor 5 is controlled to rotate slowly or pause so that the sampling mechanism 4 can take a sample and send it to the sampling component 307.

[0028] The sampling assembly 307 includes a push-and-retract hydraulic cylinder 3071 fixedly connected to the inner wall of the outer connecting slot 306 and an inner limiting slide 3072 slidably connected to the inner wall of the outer connecting slot 306. The telescopic end of the push-and-retract hydraulic cylinder 3071 is fixedly connected to the outer wall of the inner limiting slide 3072. An electronic scale 3073 is fixedly connected to the top of the inner limiting slide 3072. A sampling slot seat 3074 is provided on the top of the electronic scale 3073. The sampling slot seat 3074 includes a sampling slot seat 30741 adhered to the electronic scale 3073 and a sub-slot seat 30742 fixedly connected to the inner limit slide 3072. A pushing hydraulic cylinder 30743 is fixedly connected to the outer wall of the sampling slot seat 30741. A pushing plate 30744 is fixedly connected to the telescopic end of the pushing hydraulic cylinder 30743. A slanted material receiving plate 30745 is fixedly connected to the top of the sub-slot seat 30742. During use, as needed, the push-and-retract hydraulic cylinder 3071 is activated and controlled to push the inner limit slide 3072 along the inner wall of the outer connecting slot 306. After the sampling mechanism 4 samples brown rice and sends it to the sampling slot 30741, the push-leveling hydraulic cylinder 30743 is activated and controlled to move the push plate 30744. The push plate 30744 pushes the excess brown rice in the sampling slot 30741 to the auxiliary slot 30742. The mass of the brown rice is weighed by the electronic scale 3073, and the density of the brown rice is calculated based on the mass and unit volume. This determines whether the amount of paddy rice in the brown rice is within the acceptable range. If it meets the standard, the device continues to work. If it does not meet the standard, the machine is stopped and a suitable metal separating screen 2011 is replaced or the device is repaired. Among them, such as Figure 8As shown, the inner wall of the sampling trough 30741 is provided with a "quantitative scraper". The groove below the "quantitative scraper" in the sampling trough 30741 is a unit volume groove, and the bottom of the push plate 30744 is aligned with the "quantitative scraper". When only the unit volume groove in the sampling trough 30741 is filled with brown rice, the mass of the brown rice is weighed by the electronic scale 3073, and the density of the brown rice is calculated based on the mass and the unit volume, thereby determining whether the amount of paddy rice in the brown rice is within the qualified range.

[0029] In this embodiment, the identification marker 6 moves synchronously with the separation and lifting mechanism 2. When the monitoring probe 303 detects its position, the system can control the separation and lifting motor 5 to decelerate or pause, providing a precise operating window for the sampling mechanism 4. The sampling mechanism 4 collects samples from the brown rice layer on the belt 20231 through the linkage of the first telescopic hydraulic cylinder 401 and the second telescopic hydraulic cylinder 40311. The inner sliding frame 402 pushes open the thin layer 20233, automatically pouring the sample into the sample sampling mechanism 3. This process requires no manual intervention, avoiding efficiency loss caused by downtime sampling. The sample sampling mechanism 3 can weigh and calculate the volume of the sample, and determine in real time whether the brown rice content meets the standard. If it does not meet the standard, the system can promptly alarm or stop the machine, prompting the replacement of the metal separation mesh 2011 or equipment repair.

[0030] In a further preferred embodiment of the present invention, the base mechanism 1 includes a fixed base assembly 101, an inner wall of which is provided with a movable base 102, a toothed plate 103 is fixedly connected to the top of the movable base 102, a support column 104 is fixedly connected to the top of the movable base 102, a separation lifting motor 5 is fixedly connected to the support column 104, and the two ends of the central shaft 20211 are rotatably connected to the inner wall of the support column 104.

[0031] The fixed base assembly 101 includes a fixed base 1011, and a plurality of rolling shafts 1012 are embedded in the top of the fixed base 1011. The fixed base 1011 and the movable base 102 are in contact. A horizontal bar seat 1015 is fixedly connected to the inner wall of the fixed base 1011, and a regulating motor 1013 is fixedly connected to the outer wall of the horizontal bar seat 1015. The output shaft of the regulating motor 1013 is fixedly connected to a regulating gear 1014 through a coupling. The outer wall of the regulating gear 1014 meshes with the outer wall of the toothed plate 103, and the movable base 102 is disposed between the fixed base 1011 and the horizontal bar seat 1015. In use, the start and control motor 1013 is used to drive the control gear 1014 to rotate. Because the control gear 1014 and the toothed plate 103 work together, the movable base 102 can move back and forth within a certain range inside the fixed base 1011, thereby driving the main body of the device to perform reciprocating motion within a short stroke, thus improving the screening effect between paddy rice and brown rice.

[0032] In this embodiment, the base mechanism 1 includes a fixed base assembly 101 and a movable base 102. A regulating motor 1013 drives a regulating gear 1014 to mesh with a toothed plate 103, enabling the movable base 102 to perform short-stroke, controllable back-and-forth reciprocating motion within the fixed base 1011. This motion is transmitted to the entire separation and lifting mechanism 2, causing additional lateral shaking of the rice and brown rice mixture on the metal separation mesh 2011. This intensifies the tumbling and loosening of the material, facilitating faster and more complete passage of brown rice through the mesh openings, while also preventing rice from accumulating and becoming stuck.
