Description

Technical Field

[0001] This invention relates to the technical field of agricultural product transportation, and in particular to an intelligent transportation lifting device based on rice production and processing. Background Technology

[0002] In existing automated rice processing production lines, bucket elevators, Z-type elevators, and other material lifting equipment are the core equipment for the vertical transfer of paddy rice, brown rice, and polished rice between various processing stages. They directly determine the conveying efficiency, finished product quality, and the stability of continuous production line operation. Currently, conventional rice lifting equipment on the market generally suffers from the common industry problem of rice and rice bran dust adhering to the material plates and inner walls of the hoppers during actual production. This makes it impossible to achieve thorough unloading and cleaning, severely restricting the intelligent and continuous processing of high-quality rice. The core reasons for material adhesion are mainly multifaceted: First, after rice is milled and polished, a large amount of ultrafine rice bran powder and starch particles adhere to the surface of the rice grains. In the humid environment of the workshop, these particles are easily moistened and form a sticky medium, adhering to the inner wall of the material plate. Second, the high-speed friction between rice, bran powder, and metal or plastic material plates and hoppers easily generates static electricity, further enhancing the adsorption and adhesion effect of the fine bran powder. Third, traditional elevator material plates mostly adopt a right-angle folded edge structure, with no anti-sticking structure or flow guiding design on the inner wall. Material easily accumulates at the corners and edges, and there is no automatic material cleaning function.

[0003] Material buildup and adhesion on the conveyor plates reduces their effective volume, significantly decreasing material loading rate and equipment conveying capacity. This makes it impossible to match the production line's rated processing efficiency, hindering overall capacity improvement. Furthermore, the elevator is a closed-loop structure, and long-term residue of adhered material easily breeds mold, pests, and even harmful substances, posing not only food safety risks but also causing material mixing during batch changes, affecting the appearance and quality of the finished rice. In addition, material clumping exacerbates friction and wear on internal components, increasing motor load, energy consumption, and maintenance costs. Frequent manual shutdowns for cleaning are also necessary, resulting in high labor intensity, severe dust pollution, and safety hazards. Finally, material adhesion leads to unstable conveying flow and uneven material supply, causing disordered material level signals in upstream and downstream processing equipment, triggering idling and overflow alarms. This completely impacts the automation and unmanned continuous operation of the rice processing production line, making it difficult to meet the production demands of modern intelligent rice processing. Summary of the Invention

[0004] In view of the problem that rice tends to stick together and accumulate on the material plate in the existing technology, an intelligent transportation and lifting device based on rice production and processing is proposed.

[0005] This application provides an intelligent transport and lifting device based on rice production and processing. Its purpose is to: by adopting a cooperative structure in which a material plate is slidably embedded inside the material box, during the downward deflection of the material box, the material plate slides upward relative to the material box using the structural linkage relationship. Through the sliding cooperation between the surface of the material plate and the inner wall of the material box, the rice bran and residual rice adhering, sticking, and clumping on the inner wall of the material box can be actively scraped and cleaned.

[0006] The technical solution of the present invention is as follows: an intelligent transportation and lifting device based on rice production and processing, including a lifting cylinder, a discharge port opened at the upper end of the lifting cylinder, a feed port opened at the lower end of the lifting cylinder, and a lifting unit disposed inside the lifting cylinder, the lifting unit including a lifting component and a bottom scraping component disposed inside the lifting cylinder; The lifting component includes tension rollers disposed at the upper and lower ends of the inner wall of the elevator cylinder, a transmission belt disposed between the two tension rollers, and multiple transport components disposed on the transmission belt. Each transport component includes a mounting block disposed on the side wall of the transmission belt, a shaft rotatably disposed on the mounting block, a deflection block disposed on the outer wall of the shaft, a material box disposed at one end of the deflection block, a material plate slidably disposed inside the material box, a connecting plate disposed on the lower side wall of the mounting block, a connecting pin disposed on the side wall of the connecting plate, and a hinge rod hinged between the connecting pin and the lower end of the material plate. A variable component is installed between the shaft and the elevator cylinder. The variable component includes drive gears disposed at both ends of the shaft, and control gear plate one and control gear plate two disposed on both sides of the inner wall of the hoist cylinder, respectively. Both control gear plate one and control gear plate two are located on the movement path of the drive gears, and the drive gears are mounted on the outer wall of the shaft through damping bearings.

[0007] Furthermore, when the deflection block moves to the control tooth plate area 1, the corresponding drive gear meshes with the control tooth plate 1 and deflects towards the connecting plate. When the deflection block moves to the control tooth plate area 2, the corresponding drive gear meshes with the control tooth plate 2 and deflects back to its original position.

[0008] Furthermore, the bottom scraping component includes a square plate disposed on the inner side wall of the elevator cylinder, a support seat disposed on the side wall of the square plate, an adaptation plate rotatably disposed on the support seat, a return spring disposed between the adaptation plate and the support seat, a shaking scraper slidably disposed on the end of the adaptation plate away from the square plate, a shaking component disposed on the adaptation plate, and a collection component installed on the end of the adaptation plate away from the square plate.

[0009] Furthermore, the shaking assembly includes a guide plate disposed on the upper end of the adapting plate, a through groove formed inside the guide plate, a movable rod slidably disposed inside the through groove, a connecting rod hinged between the movable rod and the square plate, a secondary rod slidably disposed inside the movable rod, the secondary rod being fixedly connected to the side wall of the shaking scraper, and a driving element being installed between the movable rod and the adapting plate.

[0010] Furthermore, the width of the through groove is slightly larger than the length of the movable rod, allowing the movable rod to vibrate in the vertical direction.

[0011] Furthermore, the driving element includes a connecting seat disposed at the lower end of the movable rod, a driving rod rotatably disposed on the connecting seat, a limiting block disposed on the side of the connecting seat near the square plate, and a wave plate disposed at the upper end of the adapting plate, with the lower end of the driving rod located on the wave plate.

[0012] Furthermore, the collecting element includes a collecting box disposed at the lower end of the adapting plate and a collecting groove formed on the adapting plate, the collecting groove being located on one side of the shaking scraper.

[0013] Furthermore, a collection pipe is fixedly installed on the lower side wall of the collection box, and a negative pressure pump is provided at one end of the collection pipe. The collection pipe sucks the collected rice grains out of the elevator cylinder through the negative pressure pump.

[0014] The beneficial effects of this invention are: 1. By employing a sliding and embedded material plate structure within the material box, during the downward deflection of the material box, the material plate slides upward relative to the material box using structural linkage. Through the sliding contact between the material plate surface and the inner wall of the material box, adhering, sticking, and clumping rice bran and residual rice can be actively scraped and cleaned from the inner wall of the material box. Traditional elevators rely on passive material discharge via centrifugal or natural discharge. This structure enables simultaneous self-cleaning of the inner wall with each discharge cycle, avoiding the problem of long-term material accumulation and adhesion on the corners and walls of the material box, preventing residual material from becoming damp, moldy, clumping, and hardening, and eliminating the technical defects of material residue sticking to the elevator box.

[0015] 2. Through the coordinated action of the deflection of the loading box and the sliding of the material plate, the material plate eventually slides to the top of the loading box and is completely exposed. Combined with the scraping components built into the barrel, the fine bran powder and adhering rice grains on the surface of the material plate can be thoroughly scraped and cleaned, overcoming the shortcomings of traditional material plates that cannot completely clean the material and leave large amounts of residue after unloading. This effectively prevents the accumulation of adhering residue at the bottom of the elevator caused by the material plate during circulation, significantly reducing the probability of equipment jamming, belt slippage, and motor overload. At the same time, it avoids repeated friction and impact breakage of residual rice grains, significantly reducing broken rice loss during rice conveying and effectively ensuring the quality and whole rice yield of the finished product.

[0016] 3. After completing the scraping operation on the material plate, the vibrating scraper can quickly reset, generating high-frequency vibrations during the reset process. This automatically shakes off fine bran and residual rice adhering to the plate surface into the collection component, solving the secondary problems of traditional cleaning components being prone to material sticking and incomplete cleaning. The entire structure achieves comprehensive, integrated, and automatic cleaning of the inner wall of the material box, the surface of the material plate, and the cleaning scraper. No manual intervention is required to stop the machine and open the lid to clean accumulated material, significantly reducing labor intensity and dust risks, minimizing equipment downtime, and effectively ensuring the continuity and stability of rice conveying. It is suitable for the operation requirements of intelligent unattended processing production lines. Attached Figure Description

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Example 1, referring to Figures 1-4 as well as Figures 8-9 The first embodiment of the present invention provides an intelligent transport and lifting device based on rice production and processing, including a lifting cylinder 1, a discharge port 2 opened at the upper end of the lifting cylinder 1, a feed port 3 opened at the lower end of the lifting cylinder 1, and a lifting unit installed inside the lifting cylinder 1. The lifting unit includes a lifting component and a bottom scraping component installed inside the lifting cylinder 1.

[0021] The lifting components include tension rollers 101 rotatably mounted on the upper and lower ends of the inner wall of the elevator cylinder 1, a transmission belt 102 fixedly sleeved between the two tension rollers 101, and multiple transport components mounted on the transmission belt 102. Each transport component includes a mounting block 103 fixedly mounted on the side wall of the transmission belt 102, a shaft 104 rotatably mounted on the mounting block 103, a deflection block 105 fixedly mounted on the outer wall of the shaft 104, a material box 106 fixedly mounted on one end of the deflection block 105, a material plate 107 slidably mounted inside the material box 106, a connecting plate 108 fixedly mounted on the lower side wall of the mounting block 103, a connecting pin 109 fixedly mounted on the side wall of the connecting plate 108, and a hinge rod 110 hinged between the connecting pin 109 and the lower end of the material plate 107. A variable component is installed between the shaft 104 and the elevator cylinder 1.

[0022] The variable component includes drive gears 111 fixedly installed at both ends of shaft 104, and control gear plates 112 and 113 fixedly installed on both sides of the inner wall of the hoist cylinder 1. Control gear plates 112 and 113 are both located on the movement path of drive gears 111. Drive gears 111 are installed on the outer wall of shaft 104 through damping bearings.

[0023] When the deflection block 105 moves to the area of ​​the first control gear plate 112, the corresponding drive gear 111 meshes with the first control gear plate 112 and deflects towards the connecting plate 108. When the deflection block 105 moves to the area of ​​the second control gear plate 113, the corresponding drive gear 111 meshes with the second control gear plate 113 and deflects back to its original position.

[0024] Specifically, the lifting component is used to transport rice from a low position to a high position to meet the needs of subsequent rice processing. When the loading box 106 and the material plate 107 are transported upwards, the rice is in the process of being transported. The rice is located inside the loading box 106, and the material plate 107 is located below the rice for support. When the loading box 106 and the material plate 107 move downwards, they are in an unloaded state. Therefore, it is most appropriate to clean the rice adhering to their surfaces during the downward movement. Each rotation will clean the rice on the surface of the loading box 106 and the material plate 107, which can effectively reduce the time of rice adhesion, prevent rice from clumping, and effectively improve transportation efficiency.

[0025] If the material plate 107 is always located inside the material box 106, it is not convenient to clean the rice grains adhering to the surface of the material plate 107. Therefore, by designing the material plate 107 to move along the inner wall of the material box 106, the material plate 107 can clean the rice grains adhering to the inner wall of the material box 106 during the movement, and also ensure that the material plate 107 can be exposed for subsequent cleaning.

[0026] As the material container 106 and the material plate 107 move upward, the material plate 107 is located at the lowest point of the material container 106 (refer to...). Figure 9 The two work together to form a container, which can transport rice upwards synchronously during the upward movement. When the material box 106 and the material plate 107 move downwards, the deflection block 105 drives the material box 106 to deflect synchronously. Because the material plate 107 is limited by the hinge rod 110, the material plate 107 moves along its interior during the deflection of the material box 106. Therefore, the rice grains adhering to the inner wall of the material plate 107 are cleaned during the movement.

[0027] By employing a sliding fit structure where the material plate 107 is embedded inside the material box 106, during the downward deflection of the material box 106, the material plate 107 slides upward relative to the material box 106 using the structural linkage. Through the sliding fit between the surface of the material plate 107 and the inner wall of the material box 106, the rice bran and residual rice adhering, sticking, and clumping on the inner wall of the material box 106 can be actively scraped and cleaned. Traditional elevators rely on passive material discharge through centrifugal discharge and natural discharge. This structure can achieve synchronous self-cleaning of the inner wall with each discharge cycle, avoiding the problem of long-term material accumulation and layering on the corners and walls of the material box 106, preventing residual material from becoming damp, moldy, clumping, and hardening, and eliminating the technical defects of material residue sticking to the elevator cylinder 1.

[0028] The deflection of the loading box 106, combined with the upward sliding of the material plate 107, causes the material plate 107 to slide to the top of the loading box 106 and become completely exposed. This, along with the scraping component built into the elevator cylinder 1, thoroughly removes and cleans the fine bran powder and adhering rice grains from the surface of the material plate 107. This overcomes the shortcomings of traditional material plates 107, which cannot completely clean the material and leave large amounts of residue after unloading. It effectively prevents the accumulation of adhering residue at the bottom of the elevator cylinder 1 as it is carried back by the material plate 107, significantly reducing the probability of equipment jamming, belt slippage, and motor overload. Simultaneously, it prevents residual rice grains from repeatedly rubbing and impacting, significantly reducing broken rice loss during rice conveying and effectively ensuring the quality and whole rice yield of the finished product.

[0029] Example 2, refer to Figures 3-8 This is the second embodiment of the present invention, which differs from the first embodiment in that: the scraping component includes a square plate 201 fixedly installed on the inner side wall of the elevator cylinder 1, a support seat 202 fixedly installed on the side wall of the square plate 201, an adaptation plate 203 rotatably installed on the support seat 202, a return spring 204 fixedly installed between the adaptation plate 203 and the support seat 202, a shaking scraper 205 slidably installed on the end of the adaptation plate 203 away from the square plate 201, a shaking component installed on the adaptation plate 203, and a collection component installed on the end of the adaptation plate 203 away from the square plate 201.

[0030] The shaking assembly includes a guide plate 301 fixedly mounted on the upper end of the adapting plate 203, a through groove opened inside the guide plate 301, a movable rod 302 slidably mounted inside the through groove, a connecting rod 303 hinged between the movable rod 302 and the square plate 201, a secondary rod 308 slidably mounted inside the movable rod 302, the secondary rod 308 being fixedly connected to the side wall of the shaking scraper 205, and a driving element installed between the movable rod 302 and the adapting plate 203.

[0031] The width of the through slot is slightly larger than the length of the movable rod 302, allowing the movable rod 302 to vibrate vertically. The driving element includes a connecting seat 304 fixedly mounted on the lower end of the movable rod 302, a driving rod 305 rotatably mounted on the connecting seat 304, a limiting block 306 fixedly mounted on the side of the connecting seat 304 near the square plate 201, and a wave plate 307 fixedly mounted on the upper end of the adapting plate 203. The lower end of the driving rod 305 is located on the wave plate 307.

[0032] Specifically, the bottom scraping component is used to scrape and clean the rice adhering to the surface of the exposed material plate 107, preventing the rice from sticking to the surface of the material plate 107 for a long time and causing clumping or mold. The working principle of the bottom scraping component is to place the adapting plate 203 and the shaking scraper 205 at one end in the downward movement path of the deflected material plate 107, so that the lower end of each downward material plate 107 will contact the upper end of the shaking scraper 205. At the same time, the material plate 107 will exert downward pressure on the adapting plate 203 during the downward movement, and the shaking scraper 205 will scrape and clean the surface of the material plate 107 during the pressure process.

[0033] As the material plate 107 moves downward and is pressed against the lower end of the vibrating scraper 205, the vibrating scraper 205 is subjected to pressure from the lower end, causing the vibrating scraper 205 to drive the adapting plate 203 to deflect. During the deflection process, the adapting plate 203 ensures that the material plate 107 can move downward normally, while enabling the vibrating scraper 205 to scrape the surface of the material plate 107 completely.

[0034] By setting a shaking component, when the shaking scraper 205 scrapes and cleans the surface of the material plate 107, it will not shake due to the limitation of the material plate 107, thereby ensuring the stability of the material plate 107 scraping rice. When the adapting plate 203 is resetting, the shaking scraper 205 will shake briefly, and the rice adhering to the surface of the shaking scraper 205 will be shaken off during the shaking process.

[0035] The working principle of the shaking component is as follows: When the adaptation plate 203 deflects along the support seat 202, the movable rod 302 deflects synchronously with it. During the deflection process, due to the limiting of one end of the connecting rod 303, the movable rod 302 will be displaced relative to the guide plate 301. During the deflection process, the connecting rod 303 will generate a pulling force on it, causing the movable rod 302 to move in the direction of the connecting rod 303. During the reset process, the connecting rod 303 will generate a pushing force on one end of it, causing the connecting rod 303 to push the movable rod 302 away from the direction of the connecting rod 303.

[0036] When the connecting rod 303 exerts a pulling force on the movable rod 302 and causes it to move relative to the connecting rod 303, the driving rod 305 on the connecting seat 304 can deflect away from the limiting block 306. Therefore, the shaking scraper 205 will not vibrate at this time. However, when the adapting plate 203 is reset, the movable rod 302 is pushed by the connecting rod 303 and moves relative to the connecting rod. At this time, the driving rod 305 cannot deflect due to the limitation of the limiting block 306. Therefore, the driving rod 305, in cooperation with the wave plate 307, causes the movable rod 302 to drive the shaking scraper 205 to vibrate continuously, thereby shaking off the rice stuck to the surface of the shaking scraper 205.

[0037] The remaining structure is the same as that in Example 1.

[0038] Example 3, referring to Figure 6 as well as Figure 8 This is the third embodiment of the present invention, which differs from the second embodiment in that: the collecting element includes a collecting box 401 fixedly installed at the lower end of the adapting plate 203, and a collecting groove opened on the adapting plate 203, the collecting groove being located on one side of the vibrating scraper 205. A collecting pipe 402 is fixedly installed on the lower side wall of the collecting box 401, and a negative pressure pump is fixedly installed at one end of the collecting pipe 402. The collecting pipe 402 uses the negative pressure pump to suck the collected rice grains out of the elevator cylinder 1.

[0039] Specifically, the collection box 401 is used to collect and process the rice after scraping and cleaning. During the shaking process, the shaking scraper 205 shakes the rice on the side wall into the collection pipe 402 inside the collection box 401. The negative pressure generated by the negative pressure pump sucks the rice inside the collection pipe 402 out of the elevator cylinder 1 and collects the rice in a centralized manner.

[0040] The remaining structure is the same as that in Example 2.

[0041] Based on embodiments 1-3, the working principle of the present invention is as follows: The rice to be lifted enters the feed inlet 3. The two tension rollers 101 rotate, driving the transmission belt 102 and the material box 106 on its surface to rotate synchronously. When the material box 106 enters the feed inlet 3, the rice will fall directly into the material box 106 and move upward synchronously with the material plate 107 and the material box 106. After moving to the upper discharge port 2, it is discharged from the discharge port 2 by inertia during the deflection process driven by the transmission belt 102, thus completing the discharge of the rice.

[0042] As the material box 106 and the material plate 107 move downwards, the drive gear 111 at one end meshes with the control gear plate 112 and rotates. During the rotation, the shaft 104 drives the deflection block 105 and the material box 106 to deflect synchronously. During the deflection, the material plate 107 is limited by the hinge rod 110, so that during the deflection of the material box 106, the material plate 107 slides along the inner wall of the material box 106. During the sliding process, the material plate 107 scrapes and cleans the rice adhering to the inner wall of the material box 106, and one end of the material plate 107 is exposed.

[0043] As one end of the material plate 107 and one end of the loading box 106 are on the same horizontal plane and continue to move downwards, the lower end of the material plate 107 will contact and press against the upper end of the vibrating scraper 205. As the material plate 107 continues to move downwards, the vibrating scraper 205, under downward pressure, causes the adapting plate 203 to deflect on the bearing seat 202. During the deflection process, the vibrating scraper 205 remains in close contact with the surface of the material plate 107. Thus, while the material plate 107 moves downwards, the vibrating scraper 205 scrapes and cleans the surface of the material plate 107, and the material plate 107 moves downwards normally. During the deflection of the adapting plate 203, the movable rod 302, limited by the connecting rod 303, interacts with the guide plate 301. During relative motion, when the adapting plate 203 deflects, the connecting rod 303 exerts a pulling force on it, causing relative motion. Since the driving rod 305 on the connecting seat 304 can deflect away from the limiting block 306, the shaking scraper 205 will not vibrate at this time. However, when the adapting plate 203 resets, the movable rod 302 is pushed by the connecting rod 303 and undergoes relative displacement. At this time, the driving rod 305 cannot deflect due to the limitation of the limiting block 306. Therefore, with the cooperation of the driving rod 305 and the wave plate 307, the movable rod 302 drives the shaking scraper 205 to vibrate continuously, thereby shaking the rice adhering to the surface of the shaking scraper 205 into the collection box 401 for collection and processing.

[0044] After the rice adhering to the inner wall of the loading box 106 and the surface of the material plate 107 is cleaned, the drive gear 111 on the outer wall of the shaft 104 meshes with the control gear plate 113 and resets it. During the reset process, the loading box 106 and the material plate 107 reset synchronously and continue to move with the transmission belt 102 to lift the rice in the feed port 3 area.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
