Description

Technical Field

[0001] This invention relates to the field of bean sprout conveying technology, specifically a bean sprout lifting and conveying device. Background Technology

[0002] After harvesting, bean sprouts need to be bagged. Existing technologies utilize conveying devices to automatically transport bean sprouts to the packaging bags for convenient bagging. Examples include a bean sprout weighing and sorting device disclosed in Chinese Utility Model Patent No. CN202020645095.3, a bean sprout packaging machine conveyor belt feeding device disclosed in Utility Model Patent No. CN202020401067.7, a bean sprout conveying and sorting device disclosed in Utility Model Patent No. CN202120890553.4, and a bean sprout nylon mesh belt lifting and transporting device disclosed in Utility Model Patent No. CN202120490865.6, etc.

[0003] However, existing bean sprout conveying devices have the following drawbacks: 1. The overall size is large, requiring multiple people to operate during production and assembly, which makes production and assembly inconvenient, and also increases the labor intensity and error rate of workers, while also increasing production costs. 2. When bean sprouts are fed to the conveyor belt, they will pile up together and need to be dispersed manually using tools such as rakes. This operation is labor-intensive, costly, and has low production efficiency. 3. During operation, the conveyor belt may deviate, loosen, or even break due to the force of the motor and the weight of the bean sprouts, resulting in poor working stability and a short service life. 4. After washing, the bean sprouts will be transported. The moisture on the bean sprouts will stick to the conveyor belt, causing a large amount of dust, insects, hair and other foreign objects to adhere to the conveyor belt. This not only makes it difficult to clean, but also contaminates the bean sprouts, causing secondary pollution after washing.

[0004] Therefore, further improvements are necessary. Summary of the Invention

The combing device is located on the conveyor chain plate and is rotatably arranged on the body. Its rotation direction is opposite to the conveying direction of the conveyor chain plate. Alternatively, the combing device is fixedly arranged on the body.

[0007] A pre-installed positioning component is provided between the inner sides of the first steering lifting component and the second steering lifting component at their respective ends.

[0008] The upper end of the first steering lifting component and the lower end of the second steering lifting component rely on each other. The connector is positioned and inserted into the connector to achieve a pre-positioning between the first steering lifting component and the second steering lifting component. After the first steering lifting component and the second steering lifting component are pre-positioned, they are fixed to each other on the inside by fasteners and / or welding.

[0013] The lifting guide rail assembly includes a first steering lifting guide rail assembly fixedly arranged along the trajectory of the first lower steering lifting plate, and a second steering lifting guide rail assembly fixedly arranged along the trajectory of the second lower steering lifting plate.

[0014] The first lower steering lifting plate is composed of a first lower horizontal section and a first lower lifting section. The first steering lifting guide rail assembly includes a first horizontal guide rail, a second horizontal guide rail, a first inclined lifting guide rail, and a second inclined lifting guide rail. The first horizontal guide rail and the second horizontal guide rail extend horizontally and are parallel vertically. The first horizontal guide rail is fixedly mounted on the first lower horizontal section. The first inclined lifting guide rail and the second inclined lifting guide rail extend inclinedly upward and are fixedly mounted on the first lower lifting section in a parallel front-back manner.

[0015] The second lower steering lifting plate is composed of a second lower lifting section and a second lower horizontal section. The second steering lifting guide rail assembly includes a third inclined lifting guide rail, a fourth inclined lifting guide rail, a third horizontal guide rail, and a fourth horizontal guide rail. The third inclined lifting guide rail and the fourth inclined lifting guide rail extend obliquely upwards and are fixedly arranged in parallel front to back on the second lower lifting section. The third horizontal guide rail and the fourth horizontal guide rail extend horizontally and are fixedly arranged in parallel vertically on the second lower horizontal section.

[0016] An upper fixing rod and a lower fixing rod are fixedly installed at the upper and lower positions of the first lower horizontal section, respectively. The cleaning box is located below the first lower horizontal section. The lower fixing rod extends toward the cleaning box. The second horizontal guide rail is located inside the cleaning box and is fixedly installed on the lower fixing rod. The upper fixing rod extends away from the cleaning box and is fixedly installed with a feeding hopper.

[0017] There is an arc-shaped transition between the first lower horizontal segment and the first lower rising segment, and between the second lower rising segment and the second lower horizontal segment.

[0018] A first arc-shaped guide plate is fixedly provided at the arc-shaped transition position between the first lower horizontal section and the first lower lifting section, and a second arc-shaped guide plate and a third arc-shaped guide plate are fixedly provided at the arc-shaped transition position between the second lower horizontal section and the second lower lifting section.

The third arc-shaped guide plate is located between the other end of the fourth inclined lifting guide rail and the fourth horizontal guide rail.

[0020] The spraying device includes a spraying bracket and a spraying pipe. Two spraying brackets are provided and symmetrically fixed on the first lower lifting section. The spraying pipe is located above the cleaning tank and is provided on the spraying bracket. The water inlet of the spraying pipe is connected to the water in the cleaning tank or to an external water supply end. The water outlet of the spraying pipe is provided with a spray nozzle facing the conveyor chain plate.

[0021] The combing device includes a combing bracket, a combing driver, and a combing shaft. There are two combing brackets, which are located above the feeding hopper and symmetrically fixed on the first lower lifting section. The combing driver is fixed on one of the combing brackets and is driven to connect with the combing shaft. A plurality of combing rods are arranged around the combing shaft. The combing shaft rotates between the two combing brackets under the drive of the combing driver.

[0022] The surface of the conveyor chain plate is evenly distributed with multiple conveyor positioning posts, and several combing rods are evenly distributed around the combing shaft. When the combing shaft rotates, they move in and out between adjacent conveyor positioning posts or are close to or away from the conveyor positioning posts to comb the bean sprouts that are supported on the conveyor chain plate rotating on the first inclined lifting guide rail.

[0023] The outer ends of the first lower horizontal section and the second lower horizontal section are respectively rotatably equipped with a first drive shaft and a second drive shaft. The first drive shaft and the second drive shaft are respectively driven by a first drive gear and a second drive gear.

The two ends of the conveyor chain are respectively engaged and rotated on the first drive gear and the second drive gear. The middle part is sequentially supported and rotated on the first horizontal guide rail, the first arc-shaped guide plate, the first inclined lifting guide rail, the third inclined lifting guide rail, the second arc-shaped guide plate, the third horizontal guide rail, the fourth horizontal guide rail, the third arc-shaped guide plate, the fourth inclined lifting guide rail, the second inclined lifting guide rail, and the second horizontal guide rail.

[0024] The present invention, through the improvement of the above-described structure, has the following advantages compared with the prior art: 1. The intermediate component is fixed between the symmetrical plates, thus forming the first steering lifting assembly and the second steering lifting assembly. During assembly, the first and second steering lifting assemblies rely on each other and can be pre-positioned. After pre-positioning, they are then fixed to each other. This not only simplifies the structure of the first and second steering lifting assemblies and facilitates their production and processing, but also improves the assembly convenience and accuracy of the first and second steering lifting assemblies, reduces production costs, and increases production efficiency. In addition, after assembly, no assembly marks will appear on the outer surface of the machine body, which can improve the appearance neatness and precision of the machine body, and effectively ensure the assembly stability between the components, thereby improving the stability and lifespan of the machine body.

[0025] 2. Since the lifting guide rail assembly always supports the middle position of the conveyor chain plate when it rotates, it can effectively prevent the conveyor chain plate from deviating, loosening, or even breaking during operation. In addition, the conveyor chain plate also rotates along the trajectory of the lifting guide rail assembly during operation, which enables the conveyor chain plate to perform long-term and stable lifting and conveying work at the designated position, making it highly practical.

[0026] 3. A rotating or fixed combing device is used to comb the bean sprouts on the rotating conveyor chain plate, so that the bean sprouts piled on the conveyor chain plate can be broken up. This allows the bean sprouts to be evenly dispersed while being lifted and conveyed on the conveyor chain plate. This not only improves the uniform dispersion efficiency of bean sprouts and reduces the lifting and conveying time of bean sprouts, thus improving production efficiency, but also avoids manual operation, reducing labor intensity and error rate.

[0027] 4. Place at least part of the lifting guide rail assembly inside the cleaning chamber. When the conveyor chain plate rotates, at least one part of it should be inside the cleaning chamber, allowing the water inside the cleaning chamber to soak the rotating conveyor chain plate. In addition, use the spray device on the machine body or the cleaning chamber to spray and wash the conveyor chain plate. Through the combination of soaking and spraying, the conveyor chain plate can be effectively cleaned to avoid the problem of contamination of the conveyor chain plate and bean sprouts caused by foreign objects such as dust, insects, and hair adhering to the conveyor chain plate, thereby ensuring the cleanliness of the conveyor chain plate and reducing secondary contamination of bean sprouts during the lifting and conveying process.

[0045] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0046] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0047] See Figures 1-17 The bean sprout lifting and conveying equipment includes a body, which is S-shaped or Z-shaped and includes a first steering lifting component 1 and a second steering lifting component 2 whose ends can be pre-positioned and fixed to each other. The first steering lifting component 1 and the second steering lifting component 2 are respectively composed of symmetrical plates and intermediate parts located between the symmetrical plates.

[0048] In this embodiment, the intermediate component is fixed between the symmetrical plates, thereby forming the first steering lifting assembly 1 and the second steering lifting assembly 2. During assembly, the first steering lifting assembly 1 and the second steering lifting assembly 2 rely on each other and can be pre-positioned. After pre-positioning, they are then fixed to each other. This not only simplifies the structure of the first steering lifting assembly 1 and the second steering lifting assembly 2 and facilitates their production and processing, but also improves the assembly convenience and accuracy of the first steering lifting assembly 1 and the second steering lifting assembly 2, reduces production costs, and improves production efficiency. In addition, after assembly, no assembly marks will appear on the outer surface of the machine body, which can improve the appearance neatness and precision of the machine body, and effectively ensure the assembly stability between the components, thereby improving the stability and lifespan of the machine body.

[0049] The machine body is equipped with a lifting guide rail assembly, a conveyor chain plate 7, a conveyor driver 8, a cleaning box 10, and a combing device 16.

[0050] In the aforementioned components, the lifting guide rail assembly is fixedly installed along the trajectory of the machine body and is at least partially located within the cleaning chamber 10. The conveying driver 8 is driven and connected to the conveying chain plate 7. The conveying chain plate 7 is in a closed state and rotates on the lifting guide rail assembly under the drive of the conveying driver 8. During rotation, it is at least located within the cleaning chamber 10. Since the lifting guide rail assembly always supports the middle position of the conveying chain plate 7 during rotation, it can effectively prevent the conveying chain plate 7 from shifting, loosening, or even breaking during operation. In addition, the conveying chain plate 7 also rotates along the trajectory of the lifting guide rail assembly during operation, thereby enabling the conveying chain plate 7 to perform long-term and stable lifting and conveying work at a designated position, which is highly practical.

[0051] The machine body or cleaning box 10 is also equipped with a spraying device 15 for spraying and washing the conveyor chain plate 7. The combing device 16 is located on the conveyor chain plate 7. The combing device 16 is rotatably mounted on the machine body and its rotation direction is opposite to the conveying direction of the conveyor chain plate 7. Alternatively, the combing device 16 is fixedly mounted on the machine body.

[0052] A rotating or fixed combing device 16 is used to comb the bean sprouts on the rotating conveyor chain plate 7, so that the bean sprouts piled on the conveyor chain plate 7 can be broken up, so that the bean sprouts can be evenly dispersed while being lifted and conveyed on the conveyor chain plate 7. This not only improves the uniform dispersion efficiency of bean sprouts and reduces the lifting and conveying time of bean sprouts, thus improving production efficiency, but also avoids manual operation, reducing labor intensity and error rate.

[0053] At least part of the lifting guide rail assembly is placed inside the cleaning chamber 10. When the conveyor chain plate 7 rotates, at least one position is inside the cleaning chamber 10, so that the water in the cleaning chamber 10 can soak the rotating conveyor chain plate 7. In addition, the conveyor chain plate 7 is sprayed and washed using the spray device 15 on the machine body or the cleaning chamber 10. Through the combination of soaking and spraying, the conveyor chain plate 7 can be effectively cleaned to avoid the problem of contamination of the conveyor chain plate 7 and bean sprouts caused by foreign objects such as dust, insects, and hair adhering to the conveyor chain plate 7, thereby ensuring the cleanliness of the conveyor chain plate 7 and reducing secondary contamination of bean sprouts during the lifting and conveying process.

[0054] Furthermore, a pre-installed positioning component is provided between the inner sides of the first steering lifting component 1 and the second steering lifting component 2 at their respective ends. The pre-installed positioning component includes a connector 3 and a connector positioning component 4. The connector 3 is fixedly installed on the inner side of the upper end of the first steering lifting component 1, and the connector positioning component 4 is fixedly installed on the inner side of the lower end of the second steering lifting component 2. Alternatively, the connector positioning component 4 is fixedly installed on the inner side of the upper end of the first steering lifting component 1, and the connector 3 is fixedly installed on the inner side of the lower end of the second steering lifting component 2.

[0055] The upper end of the first steering lifting component 1 and the lower end of the second steering lifting component 2 rely on each other. The connector 3 is positioned and inserted into the connector positioning component 4 to achieve the pre-positioning between the first steering lifting component 1 and the second steering lifting component 2. This can improve the assembly accuracy and convenience between the first steering lifting component 1 and the second steering lifting component 2. After the first steering lifting component 1 and the second steering lifting component 2 are pre-positioned, they are fixed to each other on the inside by fasteners and / or welding.

[0056] Specifically, the inner end of the insertion positioning member 4 is pre-fixed to the inner side of the upper end of the first steering lifting assembly 1 by fasteners and / or welding, and the outer end extends out of the first steering lifting assembly 1 and is provided with an opening slot 4.1. The inner end of the insertion member 3 is pre-fixed to the inner side of the lower end of the second steering lifting assembly 2 by fasteners and / or welding, and the outer end extends out of the second steering lifting assembly 2 and is positioned and inserted into the insertion positioning member 4 through the opening slot 4.1.

[0057] After the first steering lifting assembly 1 and the second steering lifting assembly 2 are prepositioned, the outer end of the insertion positioning member 4 and the inner side of the lower end of the second steering lifting assembly 2 rely on each other and are fixed to each other by fasteners and / or welding, and / or the outer end of the insertion member 3 and the inner side of the upper end of the first steering lifting assembly 1 rely on each other and are fixed to each other by fasteners and / or welding.

[0058] In this embodiment, the inner end of the insertion positioning component 4 is pre-fixed to the inner side of the upper end of the first steering lifting component 1 by welding, and the inner end of the insertion component 3 is pre-fixed to the inner side of the lower end of the second steering lifting component 2 by welding. After the first steering lifting component 1 and the second steering lifting component 2 are pre-positioned, the outer end of the insertion positioning component 4 and the inner side of the lower end of the second steering lifting component 2 rely on each other and are fixed to each other by fasteners, so that the fixed assembly between the first steering lifting component 1 and the second steering lifting component 2 can be completed. The assembly position is accurate, and the assembly is convenient and stable.

[0059] The first steering lift assembly 1 includes left and right symmetrical first lower steering lift plates 1.1 and a first steering lift intermediate piece 1.2 located between the left and right first lower steering lift plates 1.1. The two ends of the first steering lift intermediate piece 1.2 are welded and fixed to the inner side of the left and right first lower steering lift plates 1.1 respectively. The first lower steering lift plates 1.1 are L-shaped with an initial horizontal inclination upward, and their corners are all arc-shaped or angular transitions.

[0060] The second steering lifting assembly 2 includes left and right symmetrical second lower steering lifting plates 2.1 and a second steering lifting intermediate piece 2.2 located between the left and right second lower steering lifting plates 2.1. The two ends of the second steering lifting intermediate piece 2.2 are welded and fixed to the inner side of the left and right second lower steering lifting plates 2.1 respectively. The second lower steering lifting plates 2.1 are L-shaped that initially tilts upward and extends horizontally, and their corners are all arc-shaped or angular transitions.

[0061] In this embodiment, the first lower steering lift plate 1.1 is an L-shaped structure that initially tilts horizontally upwards, with arc-shaped transitions at all corners. A first steering reinforcement 1.3 is fixedly installed at the corner of the first lower steering lift plate 1.1. The second lower steering lift plate 2.1 is an L-shaped structure that initially tilts upwards and extends horizontally, with arc-shaped transitions at all corners. A second steering reinforcement 2.3 is fixedly installed at the corner of the second lower steering lift plate 2.1.

[0062] By using the first steering reinforcement 1.3 and the second steering reinforcement 2.3, the structural strength at the corners of the first lower steering lifting plate 1.1 and the second lower steering lifting plate 2.1 can be improved, avoiding problems such as bending and breakage.

[0063] Multiple first steering lifting intermediate components 1.2 and second steering lifting intermediate components 2.2 are respectively provided and fixedly installed along the trajectory of the first lower steering lifting plate 1.1 and the second lower steering lifting plate 2.1, thereby effectively improving the structural strength of the first steering lifting assembly 1 and the second steering lifting assembly 2. In addition, after assembly, the machine body is an open S-shape in the upper and lower and front and back, which allows bean sprouts to be fed vertically at the bottom of the machine body and unloaded vertically at the top of the machine body, thereby reducing the space occupation rate. At the same time, since the machine body is open, it is convenient to clean bean sprouts, foreign objects and other objects adhering to the inner wall of the machine body and the inner components of the machine body, and it is also convenient to disassemble and maintain the inner components of the machine body.

[0064] The first lower steering lifting plate 1.1 and the second lower steering lifting plate 2.1 have opposite turning directions, and their corners are arc-shaped transitions. As a result, the machine body is S-shaped after assembly. In addition, the machine body is open after assembly, which facilitates the cleaning of bean sprouts and foreign objects adhering to the symmetrical plates and intermediate parts. It also facilitates the disassembly and maintenance of the symmetrical plates, intermediate parts, and other parts set on the above-mentioned components, making it highly practical.

[0065] The lifting guide rail assembly includes a first steering lifting guide rail assembly 5 fixedly installed along the trajectory of the first lower steering lifting plate 1.1, and a second steering lifting guide rail assembly 6 fixedly installed along the trajectory of the second lower steering lifting plate 2.1.

[0066] In this embodiment, the first steering lifting guide rail group 5 and the second steering lifting guide rail group 6 are each provided with at least two guide rails. The at least two guide rails are separated from each other, while the adjacent guide rails are connected to each other, so that the conveyor chain plate 7 can receive and rotate on at least two guide rails.

[0067] Specifically, the first lower steering lifting plate 1.1 is composed of a first lower horizontal section 1.6 and a first lower lifting section 1.7. The first steering lifting guide rail group 5 includes a first horizontal guide rail 5.1, a second horizontal guide rail 5.2, a first inclined lifting guide rail 5.3 and a second inclined lifting guide rail 5.4. The first horizontal guide rail 5.1 and the second horizontal guide rail 5.2 extend horizontally and are parallel vertically. The first horizontal guide rail 5.1 is fixedly installed on the first lower horizontal section 1.6. The first inclined lifting guide rail 5.3 and the second inclined lifting guide rail 5.4 extend inclinedly upward and are fixedly installed on the first lower lifting section 1.7 in a parallel front-to-back manner.

[0068] The second lower steering lifting plate 2.1 is composed of a second lower lifting section 2.6 and a second lower horizontal section 2.7. The second steering lifting guide rail group 6 includes a third inclined lifting guide rail 6.1, a fourth inclined lifting guide rail 6.2, a third horizontal guide rail 6.3, and a fourth horizontal guide rail 6.4. The third inclined lifting guide rail 6.1 and the fourth inclined lifting guide rail 6.2 extend inclinedly upwards and are fixedly arranged in parallel front and rear on the second lower lifting section 2.6. The third horizontal guide rail 6.3 and the fourth horizontal guide rail 6.4 extend horizontally and are fixedly arranged in parallel vertically on the second lower horizontal section 2.7.

[0069] The first lower horizontal section 1.6 is fixedly equipped with an upper fixing rod 17 and a lower fixing rod 14 at the upper and lower positions respectively. The cleaning box 10 is located below the first lower horizontal section 1.6. The lower fixing rod 14 extends toward the cleaning box 10. The second horizontal guide rail 5.2 is located inside the cleaning box 10 and is fixedly installed on the lower fixing rod 14. The upper fixing rod 17 extends away from the cleaning box 10 and is fixedly installed with a feeding hopper 18.

[0070] In this embodiment, the feeding hopper 18 and the cleaning box 10 are arranged vertically. The feeding hopper 18 is fixed above the first lower horizontal section 1.6 by the upper fixing rod 17. Bean sprouts are placed on the feeding hopper 18 by a robot or manually. The feeding hopper 18 then collects the bean sprouts and places them on the conveyor chain plate 7 rotating above the first lower horizontal section 1.6, thereby achieving centralized feeding of bean sprouts. The second horizontal guide rail 5.2 is fixed below the first lower horizontal section 1.6 by the lower fixing rod 14, so that the conveyor chain plate 7 rotating on the second horizontal guide rail 5.2 can be immersed in the cleaning water in the cleaning box 10, thereby achieving cleaning of the conveyor chain plate 7.

[0071] The bottom of the cleaning chamber 10 is provided with a chamber support leg 10.1, and the chamber is tilted to one side by the chamber support leg 10.1. A switch valve 10.2 is provided below the tilted side of the cleaning chamber 10.

[0072] The bottom of the cleaning tank 10 is tilted to the other side by a tank support 10.1 on one side. At the same time, the switch valve 10.2 is located below the tilted side of the cleaning tank 10. The user can open the switch valve 10.2 to allow the water in the cleaning tank 10 to flow out automatically. The structure is simple and reasonable and easy to use.

[0073] The transitions between the first lower horizontal segment 1.6 and the first lower rising segment 1.7, and between the second lower rising segment 2.6 and the second lower horizontal segment 2.7, are all curved.

[0074] A first arc-shaped guide plate 11 is fixedly installed at the arc-shaped transition position between the first lower horizontal section 1.6 and the first lower lifting section 1.7. A second arc-shaped guide plate 12 and a third arc-shaped guide plate 13 are fixedly installed at the arc-shaped transition position between the second lower horizontal section 2.7 and the second lower lifting section 2.6.

[0075] The first arc-shaped guide plate 11 is located between the first horizontal guide rail 5.1 and the first inclined lifting guide rail 5.3. One end of the third inclined lifting guide rail 6.1 is connected to the first inclined lifting guide rail 5.3. The second arc-shaped guide plate 12 is located between the other end of the third inclined lifting guide rail 6.1 and the third horizontal guide rail 6.3. One end of the fourth inclined lifting guide rail 6.2 is connected to the second inclined lifting guide rail 5.4. The third arc-shaped guide plate 13 is located between the other end of the fourth inclined lifting guide rail 6.2 and the fourth horizontal guide rail 6.4.

[0076] In this embodiment, the first steering reinforcement 1.3 is disposed on the outer side of the corner of the first steering lifting assembly 1, the first arc-shaped guide plate 11 is disposed on the inner side of the corner of the first steering lifting assembly 1, the second steering reinforcement 2.3 is disposed on the outer side of the corner of the second steering lifting assembly 2, and the second arc-shaped guide plate 12 and the third arc-shaped guide plate 13 are respectively disposed on the inner side of the corner of the second steering lifting assembly 2. The first steering reinforcement 1.3 corresponds to the first arc-shaped guide plate 11 internally and externally, and the second steering reinforcement 2.3 corresponds to the second arc-shaped guide plate 12 and the third arc-shaped guide plate 13 internally and externally. This can further improve the structural strength of the first steering lifting assembly 1 and the second steering lifting assembly 2, and improve the stability and lifespan of the machine body. In addition, the first arc-shaped guide plate 1... 1. The arrangement of the second arc-shaped guide plate 12 and the third arc-shaped guide plate 13 allows arc-shaped transitions to be formed between the first horizontal guide rail 5.1 and the first inclined lifting guide rail 5.3, between the third inclined lifting guide rail 6.1 and the third horizontal guide rail 6.3, and between the fourth inclined lifting guide rail 6.2 and the fourth horizontal guide rail 6.4. This enables the conveyor chain plate 7 to achieve arc-shaped filtering between horizontal and inclined conveying, effectively reducing friction at corners and dispersing the force acting on the conveyor chain plate 7, resulting in more uniform stress distribution. This prevents deformation or even breakage of the conveyor chain plate 7, thereby improving the stability of the conveyor chain plate 7 at the turning points of the first turning lifting guide rail group 5 and the second turning lifting guide rail group 6.

[0077] After assembly, the body forms an S-shape by utilizing the arc transitions between the first lower horizontal section 1.6 and the first lower lifting section 1.7, and between the second lower lifting section 2.6 and the second lower horizontal section 2.7.

[0078] The spray device 15 includes a spray bracket 15.1 and a spray pipe 15.2. There are two spray brackets 15.1, which are symmetrically fixed on the first lower lifting section 1.7. The spray pipe 15.2 is located above the cleaning box 10 and is set on the spray bracket 15.1. The water inlet end of the spray pipe 15.2 is connected to the water in the cleaning box 10 or to the external water supply end. The water outlet end of the spray pipe 15.2 is provided with a spray nozzle 15.3 facing the conveyor chain plate 7.

[0079] In this embodiment, the spray nozzle 15.3 first sprays and washes the surface of the conveyor chain plate 7 rotating below the first lower lifting section 1.7 to complete the pre-cleaning of the conveyor chain plate 7. The dirt sprayed out will fall directly into the cleaning box 10. The conveyor chain plate 7 that continues to rotate then enters the cleaning box 10 for soaking to complete the final cleaning of the conveyor chain plate 7, so as to ensure the effective cleaning of the conveyor chain plate 7.

[0080] The spraying direction of the spray nozzle 15.3 is perpendicular to the direction of the conveyor chain plate 7, so that the cleaning liquid sprayed by the spray nozzle 15.3 can directly act on the surface of the conveyor chain plate 7, improving the cleaning effect. In addition, the spray pipe 15.2 can be connected to the water in the cleaning tank 10, so that the water in the cleaning tank 10 can be recycled, achieving both soaking and spraying. Furthermore, the spray pipe 15.2 can also be connected to an external water supply terminal to use external water to spray and clean the conveyor chain plate 7.

[0081] Two spray brackets 15.1 are symmetrically fixed to the bottom side of the first lower lifting section 1.7, and movable adjustment parts 15.4 are provided on them. The movable adjustment parts 15.4 are adjustablely mounted on the spray brackets 15.1, and the spray pipes 15.2 are fixedly mounted on the movable adjustment parts 15.4.

[0082] In this embodiment, the movable adjusting member 15.4 is provided with an adjusting groove, and the spray bracket 15.1 is provided with a fixing hole. The fixing hole and the adjusting groove correspond to each other, and a fastener is provided between them. By using the tightening and loosening of the fastener, the position between the movable adjusting member 15.4 and the spray bracket 15.1 can be adjusted, thereby adjusting the distance of the spray nozzle 15.3 acting on the conveyor chain plate 7.

[0083] The combing device 16 includes a combing bracket 16.1, a combing driver 16.2, and a combing shaft 16.3. There are two combing brackets 16.1, which are located above the feeding hopper 18 and symmetrically fixed on the first lower lifting section 1.7. The combing driver 16.2 is fixed on one of the combing brackets 16.1 and is drivenly connected to the combing shaft 16.3. Several combing rods 16.4 are arranged around the combing shaft 16.3. The combing shaft 16.3 rotates between the two combing brackets 16.1 under the drive of the combing driver 16.2.

[0084] In this embodiment, the combing shaft 16.3 is assembled using two symmetrical combing brackets 16.1, so that the combing shaft 16.3 spans across the conveyor chain plate 7, and the combing driver 16.2 drives the combing shaft 16.3 to rotate when it is working.

[0085] Multiple conveyor positioning posts 7.1 are evenly distributed on the surface of the conveyor chain plate 7, and several combing rods 16.4 are evenly distributed around the combing shaft 16.3, and move in and out between adjacent conveyor positioning posts 7.1 or close to and away from the conveyor positioning posts 7.1 when the combing shaft 16.3 rotates, so as to comb the bean sprouts on the conveyor chain plate 7 that is supported by the first inclined lifting guide rail 5.3.

[0086] In this embodiment, bean sprouts are fed from the feeding hopper 18 and piled up on the conveyor chain plate 7. The conveyor chain plate 7 lifts and conveys the bean sprouts upward. When the bean sprouts are lifted and conveyed, they pass through the combing device 16. The combing shaft 16.3 is opposite to the direction of the bean sprout lifting and conveying. The positions of several combing rods 16.4 are staggered from the positions of the conveying positioning columns 7.1, so that when the combing shaft 16.3 rotates, the combing rods 16.4 can move in and out between adjacent conveying positioning columns 7.1 to break up the bean sprouts piled on the conveyor chain plate 7.

[0087] A combing cover 16.5 is provided between the left and right combing supports 16.1. The combing cover 16.5 flips between the left and right combing supports 16.1 and covers or exposes the combing shaft 16.3 when flipped. A protective cover 16.6 is also fixedly provided between the left or right combing supports 16.1 and the combing driver 16.2.

[0088] In this embodiment, the combing cover plate 16.5 is flipped to cover or expose the combing shaft 16.3. When the combing shaft 16.3 is exposed, it is convenient for workers to perform daily maintenance on the combing shaft 16.3 and manually sort the bean sprouts, so as to avoid the bean sprouts causing the combing shaft 16.3 to get stuck and thus improve the combing stability of the bean sprouts.

[0089] A combing reinforcement rod 16.7 and a back plate 16.8 are also fixedly installed between the left and right combing supports 16.1. The back plate 16.8 is located on one side of the left and right combing supports 16.1 and covers one side of the combing shaft 16.3. A hinge 16.9 is provided between the back plate 16.8 and the combing cover plate 16.5. The combing cover plate 16.5 has a 7-shaped cross section and is hinged and flipped on the back plate 16.8 through the hinge 16.9. When the combing cover plate 16.5 is hinged and flipped, it covers or exposes the top and other side of the combing shaft 16.3. When the combing cover plate 16.5 covers the combing shaft 16.3, it is fixed between the left and right combing supports 16.1 by fasteners, magnets, or buckles.

[0090] In this embodiment, two combing reinforcement rods 16.7 are provided. The two combing reinforcement rods 16.7 are fixed between the upper parts of the left and right combing brackets 16.1 at a distance from each other. The lower parts of the left and right combing brackets 16.1 are fixed to the machine body, thereby improving the assembly stability between the left and right combing brackets 16.1. In addition, by using the cooperation of the back plate 16.8 and the combing cover plate 16.5, the front, rear, sides and top of the combing shaft 16.3 can be blocked, so that the bean sprouts on the conveyor chain plate 7 are broken up by the combing shaft 16.3. This not only effectively protects the combing shaft 16.3, but also prevents the bean sprouts from flying around due to the combing work of the combing shaft 16.3.

[0091] The outer ends of the first lower horizontal section 1.6 and the second lower horizontal section 2.7 are respectively rotatably equipped with a first drive shaft 1.4 and a second drive shaft 2.4. The first drive shaft 1.4 and the second drive shaft 2.4 are respectively driven by a first drive gear 1.5 and a second drive gear 2.5. The conveyor driver 8 is fixedly installed on the first lower horizontal section 1.6 or the second lower horizontal section 2.7 and is drivenly connected to the first drive shaft 1.4 or the second drive shaft 2.4. The two ends of the conveyor chain 7 are respectively engaged and rotated on the first drive gear 1.5 and the second drive gear 2.5. The middle part sequentially receives and rotates on the first horizontal guide rail 5.1, the first arc-shaped guide plate 11, the first inclined lifting guide rail 5.3, the third inclined lifting guide rail 6.1, the second arc-shaped guide plate 12, the third horizontal guide rail 6.3, the fourth horizontal guide rail 6.4, the third arc-shaped guide plate 13, the fourth inclined lifting guide rail 6.2, the second inclined lifting guide rail 5.4, and the second horizontal guide rail 5.2.

[0092] In this embodiment, the conveyor driver 8 is fixedly mounted on the second lower horizontal section 2.7 and is drivenly connected to the second transmission shaft 2.4. The conveyor driver 8, in cooperation with the second transmission gear 2.5, drives the two ends of the conveyor chain plate 7 to mesh and rotate on the first transmission gear 1.5 and the second transmission gear 2.5. The middle section sequentially receives and rotates on the first horizontal guide rail 5.1, the first arc-shaped guide plate 11, the first inclined lifting guide rail 5.3, the third inclined lifting guide rail 6.1, the second arc-shaped guide plate 12, the third horizontal guide rail 6.3, the fourth horizontal guide rail 6.4, the third arc-shaped guide plate 13, the fourth inclined lifting guide rail 6.2, the second inclined lifting guide rail 5.4, and the second horizontal guide rail 5.2.

[0093] Because the lifting guide rail assembly always supports the middle position of the conveyor chain plate 7 when it rotates, it can effectively prevent the conveyor chain plate 7 from deviating, loosening, or even breaking during operation. In addition, the conveyor chain plate 7 also rotates along the trajectory of the lifting guide rail assembly during operation, so that the conveyor chain plate 7 can perform long-term and stable lifting and conveying work at the designated position, which is highly practical.

[0094] A support frame 9 is also fixedly installed on the first steering lifting assembly 1 and / or the second steering lifting assembly 2.

[0095] In this embodiment, a first transverse rod 19 is transversely inserted between the first lower horizontal segments 1.6, which are symmetrical on both sides. A first support connecting block 20 is fixedly installed at both ends of the first transverse rod 19. A second transverse rod 21 is transversely inserted between the first lower lifting segments 1.7, which are symmetrical on both sides. A second support connecting block 22 is fixedly installed at both ends of the second transverse rod 21. A third transverse rod 23 is transversely inserted between the second lower lifting segments 2.6, which are symmetrical on both sides. A third support connecting block 24 is fixedly installed at both ends of the third transverse rod 23. The support frame 9 is fixed to the first support connecting block 20, the second support connecting block 22, and the third support connecting block 24, which not only improves the stability of the support frame 9 and the machine body, but also provides support for the entire machine body, ensuring the stable operation of the bean sprout conveyor. In addition, the support frame 9 is fixed to the outside of the machine body by means of external fixation, so it will not affect the internal components of the machine body. This not only improves the space utilization rate, but also avoids damage to the internal components of the machine body, and also facilitates the daily disassembly and maintenance of the components.

[0096] Below the second lower horizontal section 2.7, the second lower lifting section 2.6, and the first lower lifting section 1.7, there are also fixed receiving plates 25. The receiving plates 25 are inclined from top to bottom, and their lower inclined end is located above the washing box 10. This allows the bean sprouts that cannot be completely unloaded when they are lifted and conveyed to the top of the machine and are stuck to the conveyor chain plate 7 to fall onto the receiving plates 25 when they rotate back to the second lower horizontal section 2.7, the second lower lifting section 2.6, and the first lower lifting section 1.7. They will then automatically fall into the washing box 10 through the receiving plates 25. This not only improves the bean sprout recovery rate but also reduces environmental pollution.
