Description

Technical Field

[0001] The invention relates to a chain bucket type truck unloading and cleaning integrated machine, belonging to the technical field of chain bucket type truck unloading machines. Background Art

[0002] A chain bucket car unloader is a piece of machinery specifically designed for unloading railway freight cars. It primarily consists of a gantry, a chain bucket elevator and its lifting mechanism, a belt conveyor, and a travel mechanism. Chain bucket car unloaders are primarily used to unload bulk materials such as coal, sand, lime, coke, and other granular materials from freight cars within industrial and mining enterprises.

[0003] At present, chain bucket unloaders are generally used to unload materials from railway open cars. The traditional unloading method is that a bucket elevator is lowered into the open car to be unloaded, and the reciprocating chain bucket scoops out the material and lifts it to a certain height, pouring it into the unloading hopper, and then leaking it into the conveyor belt through the unloading hopper to realize the unloading operation. For example: Announcement No. CN215923808U, a car unloader, which includes a door-shaped bracket and a lifting frame installed on the door-shaped bracket, a motor installed on the lifting frame, a transmission sprocket installed on the motor, a chain installed on the transmission sprocket, and a chain bucket fixed on the chain to form a chain bucket unloader. The unloader realizes the unloading operation of the material in the car through the reciprocating motion of the chain bucket. However, in the actual unloading process, due to the large turning radius of the reciprocating chain bucket, the bucket elevator unloads the material in the open car to be unloaded. Since there is a dead angle between the bucket elevator and the inner wall of the open car to be unloaded (the chain bucket forms an arc angle with the inner wall during the turning process after taking out the material, and the side wall and the bottom of the open car are at a vertical angle, so the material accumulated in the area formed by the arc angle and the vertical angle cannot be taken out by the chain bucket. This position is called a dead angle), resulting in incomplete cleaning of the bucket elevator material. Manual cleaning is required. On the one hand, manual cleaning work is labor-intensive, and on the other hand, it is time-consuming and labor-intensive, resulting in low unloading efficiency.

[0004] The current existing method is to use a car unloading sweeper to clean the materials unloaded by the chain bucket unloader, thereby completing the unloading operation. However, in order to unload the materials, the company needs to purchase an additional sweeper, which increases the cost of purchasing the sweeper. Moreover, the use of a sweeper cannot solve the problem of low unloading efficiency, and a certain amount of investment is still required to complete the unloading operation. In addition, during railway train transportation, when train cars transport bulk materials (such as coal), the number of cars generally reaches dozens or even hundreds. When using a chain bucket unloader and a sweeper to unload the car, the unloading is affected and the car's residence time is prolonged, which also affects the scheduling of the car's entry and exit.

[0005] Therefore, in order to solve the above problems, it is urgent to propose a chain bucket type unloading and cleaning integrated equipment to achieve thorough unloading and improve unloading efficiency. Summary of the Invention

[0006] In order to solve the above problems, the present invention proposes a chain bucket type unloading and cleaning integrated equipment and unloading cleaning method to solve the problem that the current existing chain bucket type unloading machine does not unload bulk materials thoroughly, and still needs to be cleaned again manually or using a cleaning machine after unloading, resulting in high labor intensity, low unloading efficiency, high unloading time, and increased costs.

[0007] The technical solution adopted by the present invention to solve the above-mentioned technical problems is:

[0008] A chain bucket type truck unloading and cleaning integrated device, comprising:

[0009] The gantry is used to walk on the track on the ground. The gantry is a stable working platform and provides an installation and walking platform for the chain bucket lifting and reclaiming mechanism;

[0010] The chain bucket lifting and reclaiming mechanism is slidably mounted on the door frame and is used to dig out bulk materials. It includes a guide frame and a chain bucket mechanism mounted on the guide frame.

[0011] The cleaning and collecting mechanism comprises a storage frame and a cleaning mechanism. The storage frame is installed on the guide frame, and the cleaning mechanism is slidably installed in the storage frame.

[0012] Preferably, a first conveying mechanism is installed on the door frame.

[0013] Preferably, a second conveying mechanism is further included, one end of the second conveying mechanism is hinged on the door frame, a lifting rope is installed on the door frame, and the lifting rope is connected to the other end of the second conveying mechanism.

[0014] Preferably: the cleaning mechanism includes a scissors frame, a lifting frame, a scraper mechanism and a vertical brush mechanism, one end of the scissors frame is installed on the storage frame, and the other end is installed with a lifting frame, the scraper mechanism is installed at the lower end of the lifting frame, and vertical brush mechanisms are installed on both sides of the scraper mechanism.

[0015] Preferably, a first oil cylinder is installed on the storage frame, and an output end of the first oil cylinder is connected to the scissors frame to realize the storage or extension of the scissors frame in the storage frame.

[0016] Preferably, the scraper mechanism includes a scraper housing, a motor, an active scraper sprocket, a driven scraper sprocket, a scraper chain, and a scraper. The scraper housing has a material ejection port at its upper portion. The motor is mounted on the upper end of the scraper housing. The active scraper sprocket is mounted on the motor. The driven scraper sprocket is mounted on the lower end of the scraper housing via a rotating shaft and a bearing seat. The active scraper sprocket and the driven scraper sprocket are connected and mounted via a scraper chain. A plurality of scrapers are mounted on the scraper chain. The rotation of the motor drives the scraper chain to circulate, forming a material storage area between adjacent scrapers. The scrapers scrape bulk material from the bottom into the interior of the scraper housing. The scrapers cooperate with the inner wall of the scraper housing to lift the bulk material in the scraper housing and ultimately eject it through the material ejection port.

[0017] Preferably: the vertical brush mechanism includes a vertical brush rotating motor, a vertical brush, a vertical brush rotating frame and a corner brush. The vertical brush rotating frame is installed on the side wall of the scraper mechanism, and the vertical brush is installed on the vertical brush rotating frame through a bearing seat. The vertical brush rotating frame is also installed with a vertical brush rotating motor. The upper end of the vertical brush is installed in conjunction with the vertical brush rotating motor, and the lower end of the vertical brush is installed with a corner brush.

[0018] Preferably, the chain bucket mechanism includes a hopper fixed on the chain. Driven by the active roller, the hopper at the bottom scoops up the material and rises to the top along with the chain, and unloads the material onto the first conveying mechanism by turning over.

[0019] A chain bucket type unloading vehicle cleaning method is implemented based on a chain bucket type unloading vehicle cleaning integrated device, comprising the following steps:

[0020] Step S1, controlling the gantry to move to the end of the truck to be unloaded, and adjusting the position of the chain bucket lifting and reclaiming mechanism on the gantry so that the lifting and reclaiming mechanism is directly above the truck to be unloaded;

[0021] Step S2, controlling the chain bucket mechanism in the chain bucket lifting and reclaiming mechanism to fall, so that the hopper in the chain bucket mechanism digs the bulk material from one end of the truck to be unloaded until the bulk material at the end of the truck to be unloaded is emptied;

[0022] Step S3: Control the gantry to move so that the bulk materials dug by the chain bucket mechanism can leave working space for the cleaning mechanism;

[0023] Step S4: Extend the cleaning mechanism from the storage frame, and make the vertical brush mechanism of the cleaning mechanism fit against the inner wall of the end of the truck to be unloaded;

[0024] Step S5, start the cleaning mechanism, the vertical brush mechanism of the cleaning mechanism rotates to clean the inner wall of the truck to be unloaded, and clean the bulk materials remaining on the inner wall to the bottom of the truck to be unloaded. At the same time, start the scraper mechanism, and the scraper mechanism lifts the cleaned bulk materials through the reciprocating motion of the scraper and throws them into the working area of ​​the chain bucket mechanism through the material throwing port, and unloads the materials onto the first conveying mechanism as the chain bucket mechanism is in working condition.

[0025] A chain bucket type unloading vehicle cleaning method is implemented based on a chain bucket type unloading vehicle cleaning integrated device, comprising the following steps:

[0026] Step 1: Control the gantry to move to the end of the truck to be unloaded, and adjust the position of the chain bucket lifting and reclaiming mechanism on the gantry so that the lifting and reclaiming mechanism is directly above the truck to be unloaded;

[0027] Step 2: Control the chain bucket mechanism in the chain bucket lifting and reclaiming mechanism to fall. The hopper in the chain bucket mechanism starts from one end of the truck to be unloaded and digs out bulk materials layer by layer. When the last layer of bulk materials is dug out, the cleaning mechanism extends from the storage frame and makes the vertical brush mechanism of the cleaning mechanism fit on the inner wall of the end of the truck to be unloaded.

[0028] Step 3: Start the cleaning mechanism, and the vertical brush mechanism of the cleaning mechanism rotates to clean the inner wall of the truck to be unloaded, and clean the bulk materials remaining on the inner wall to the bottom of the truck to be unloaded. At the same time, start the scraper mechanism, and the scraper mechanism lifts the cleaned bulk materials through the reciprocating motion of the scraper and throws them into the working area of ​​the chain bucket mechanism through the material throwing port, and unloads the materials onto the first conveying mechanism as the chain bucket mechanism is in working condition.

[0029] The beneficial effects of the present invention are as follows: the chain bucket type truck unloading and cleaning device not only improves operational efficiency and safety by achieving simultaneous unloading and cleaning, but also effectively reduces labor costs, coal dust pollution, and equipment wear, thereby improving overall production efficiency and environmental standards. Furthermore, this automated cleaning method can optimize resource allocation, improve the cleanliness of the working environment, and reduce downtime and operating costs.

DETAILED DESCRIPTION

[0056] The present invention is further illustrated below with reference to specific examples. It should be understood that these examples are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, modifications of various equivalent forms of the present invention made by those skilled in the art all fall within the scope defined by the claims attached to this application. Specific implementation method one:

[0058] In conjunction with the instructions Figures 1-11 , explaining this embodiment, this embodiment discloses a chain bucket type unloading and cleaning integrated device, comprising:

[0059] The gantry 1 is a gantry structure assembled by welding steel structures and used for traveling on the ground track. It can provide a stable working platform for the operation of the entire chain bucket unloader. A traveling mechanism 28 is installed at the bottom of the gantry 1. The traveling mechanism includes traveling wheels, a reducer and a traveling motor. The traveling wheels are rotatably mounted on the bottom of the gantry 1 through bearings, and the traveling wheels are driven to rotate by the traveling motor and reducer, so that the entire gantry 1 can travel on the ground track.

[0060] The chain bucket lifting and material-retrieving mechanism 2 is slidably mounted on the gantry 1 and is used to dig bulk materials. It includes a guide frame 3 and a chain bucket mechanism 4 mounted on the guide frame 3; wherein, the guide frame 3 is a square frame formed by welding and assembling steel beams or square tubes, and walking wheels and a motor reducer for driving the walking wheels are installed on the guide frame 3. A track is laid on the gantry 1, and the walking wheels of the guide frame 3 are mounted on the track of the gantry 1. The position of the guide frame 3 on the gantry 1 is adjusted by the walking wheels to align the chain bucket mechanism 4 with the truck to be unloaded in the gantry 1; in addition, the chain bucket mechanism 4 is slidably mounted in the guide frame 3, and the chain bucket mechanism 4 can realize rising or falling movements along the guide frame 3; the chain bucket mechanism 4 includes a bucket 27 fixed on the chain. Driven by the active roller, the bucket 27 at the bottom scoops up the material and rises to the top with the chain, and unloads the material onto the first conveying mechanism 8 by flipping.

[0061] The cleaning and collecting mechanism 5 includes a receiving frame 6 and a cleaning mechanism 7. The receiving frame 6 is mounted on the guide frame 3, and the cleaning mechanism 7 is slidably mounted in the receiving frame 6. When the cleaning mechanism 7 is working, the cleaning mechanism 7 extends from the receiving frame 6. When the cleaning mechanism 7 does not need to work, the cleaning mechanism 7 is stored in the receiving frame 6, thereby increasing the operating range of the chain bucket lifting and reclaiming mechanism 2 and preventing its range of movement from being interfered with by the cleaning mechanism 7. This allows the entire chain bucket unloading cleaning equipment to have a good activity space, thereby improving the space utilization rate and flexibility of the equipment.

[0062] The cleaning mechanism 7 includes a scissors frame 11, a lifting frame 12, a scraper mechanism 13 and a vertical brush mechanism 14. One end of the scissors frame 11 is installed on the storage frame 6, and the other end is installed with the lifting frame 12. The scraper mechanism 13 is installed at the lower end of the lifting frame 12, and vertical brush mechanisms 14 are installed on both sides of the scraper mechanism 13.

[0063] The scraper mechanism 13 includes a scraper housing 16, a motor 17, an active scraper sprocket 18, a driven scraper sprocket 19, a scraper chain 20 and a scraper 21. The upper portion of the scraper housing 16 has a material ejection port 22. The motor 17 is mounted on the upper end of the scraper housing 16. The active scraper sprocket 18 is mounted on the motor 17. The driven scraper sprocket 19 is mounted on the lower end of the scraper housing 16 through a rotating shaft and a bearing seat. The active scraper sprocket 18 and the driven scraper sprocket 19 are connected and installed through the scraper chain 20. A plurality of scrapers 21 are installed on the scraper chain 20. Figure 11 As shown, the active scraper sprocket 18 is driven to rotate by the rotation of the motor 17, and the active scraper sprocket 18 drives the scraper chain 20 to circulate, and a material storage area is formed between two adjacent scrapers 21. The scraper 21 scrapes the bulk material at the bottom into the scraper shell 16, and through the cooperation between the scraper 21 and the inner wall of the scraper shell 16, the bulk material in the scraper shell 16 is lifted and finally thrown out through the material throwing port 22.

[0064] The vertical brush mechanism 14 includes a vertical brush rotating motor 23, a vertical brush 24, a vertical brush rotating frame 25 and a corner brush 26. The vertical brush rotating frame 25 is installed on the side wall of the scraper mechanism 13. The vertical brush 24 is installed on the vertical brush rotating frame 25 through a bearing seat. The vertical brush rotating motor 23 is also installed on the vertical brush rotating frame 25. The upper end of the vertical brush 24 is installed in conjunction with the vertical brush rotating motor 23, and the lower end of the vertical brush 24 is installed with a corner brush 26.

[0065] The cleaning mechanism 7 is able to retract or extend the storage frame 6 through the action of the first oil cylinder 15. Specifically, the storage frame 6 is equipped with the first oil cylinder 15, and the output end of the first oil cylinder 15 is connected to the scissors frame 11 for retracting or extending the scissors frame 11 in the storage frame 6.

[0066] In this embodiment, the working principle of a chain bucket type unloading and cleaning integrated device is:

[0067] Taking the simultaneous unloading and cleaning operation of a train open car (for coal transportation) as an example, when the train open car enters the unloading area and stops, the gantry 1 is first controlled to move to the end of the wagon to be unloaded, and the position of the chain bucket lifting and reclaiming mechanism 2 on the gantry 1 is adjusted so that the lifting and reclaiming mechanism 2 is directly above the wagon to be unloaded; secondly, the chain bucket mechanism 4 in the chain bucket lifting and reclaiming mechanism 2 is controlled to fall, and the hopper 27 in the chain bucket mechanism 4 deeply digs bulk materials from one end of the wagon to be unloaded until the bulk materials at the end of the wagon to be unloaded are emptied; thirdly, the gantry 1 is controlled to move a certain distance so that the bulk materials dug by the chain bucket mechanism 4 can leave working space for the cleaning mechanism 7; Again, the cleaning mechanism 7 is extended from the storage frame 6, and the vertical brush mechanism 14 of the cleaning mechanism 7 is attached to the inner wall of the end of the truck to be unloaded; finally, the cleaning mechanism 7 is started, and the vertical brush mechanism 14 of the cleaning mechanism 7 rotates to clean the inner wall of the truck to be unloaded, and the bulk materials remaining on the inner wall are swept to the bottom of the truck to be unloaded. At the same time, the scraper mechanism 13 is started, and the scraper mechanism 13 lifts the cleaned bulk materials through the reciprocating scraper 21 and throws them into the working area of ​​the chain bucket mechanism 4 through the material throwing port 22, and with the chain bucket mechanism 4 in the working state, the materials are unloaded onto the first conveying mechanism 8.

[0068] In this embodiment, during the coal unloading operation on the train, the chain bucket unloader with its own cleaning function can realize the simultaneous unloading and cleaning, which fully ensures the positive effects of industrial and mining enterprises in improving work efficiency, reducing costs, and ensuring safety. The advantages are as follows:

[0069] 1. Improve operational efficiency. Simultaneous unloading and cleaning can significantly improve work efficiency. Compared with traditional coal unloading, traditional operations usually unload coal first and then clean up. This operation is time-consuming, especially when unloading large quantities of coal. The chain bucket unloader's built-in cleaning function can clean while unloading coal, not only reducing idle time but also avoiding downtime due to cleaning. In addition, its consistency and efficiency shorten the total time of each unloading cycle, improving overall production efficiency.

[0070] 2. Reduce labor costs. The simultaneous unloading and cleaning operation significantly reduces the need for manual intervention. In traditional unloading, manual cleaning is often required after unloading, increasing labor consumption. However, the chain bucket unloader with built-in cleaning function can achieve automated cleaning, eliminating the need for repeated cleaning personnel or additional cleaning operations after unloading, significantly reducing labor costs.

[0071] 3. Improve operational safety. During coal unloading, coal slag, coal fragments, and coal dust often fall onto the tracks or the work area. If these materials are not cleaned up promptly, they can easily cause workers to slip or equipment to malfunction. Synchronous cleaning effectively reduces these falling materials and reduces the risk of accidents caused by uneven surfaces or accumulated coal fragments. It also keeps the work site clean and ensures a safe working environment.

[0072] 4. Improve the cleanliness of the working environment. The cleaning function can clean the work site in real time during the coal unloading process, preventing the accumulation of coal dust, coal slag and other waste materials on the ground and in the surrounding area, thereby keeping the workplace clean and tidy. This not only improves the working environment for staff, but also enhances the company's image. The application of the cleaning function is particularly important in companies that focus on environmental protection and site cleanliness.

[0073] 5. Reduced downtime. In traditional coal unloading operations, unloading and cleaning must be performed separately, often resulting in idle downtime. In particular, unloading can be temporarily halted during the cleaning process, resulting in reduced production efficiency. The chain bucket unloader's built-in cleaning function allows for simultaneous unloading and cleaning, minimizing idle time and improving operational continuity and efficiency.

[0074] 6. The chain bucket unloader's built-in cleaning function optimizes equipment and personnel allocation. Tasks that previously required multiple devices and more manpower can now be completed with a single device and a single operator. This not only improves resource utilization but also streamlines and simplifies operational processes, reducing unnecessary resource waste and lowering operating costs.

[0075] 7. Enhanced operational automation: The chain bucket unloader's built-in cleaning function enhances the automation of the entire coal unloading process. Automated cleaning reduces manual intervention and enhances the intelligence of the operational process. This increased automation not only reduces errors caused by human error but also reduces operator workload, making operations safer and more precise.

[0076] 8. Improved overall operational efficiency. Overall, the use of the chain bucket unloader's built-in cleaning function makes the entire coal unloading process more efficient, energy-saving, environmentally friendly, and safe. By eliminating unnecessary operations and reducing operating costs, companies can significantly improve overall operational efficiency. This advantage becomes more pronounced over long periods of operation, especially in large-scale coal unloading operations, saving companies significant manpower, material resources, and time. Specific implementation method 2:

[0078] In conjunction with the instructions Figures 1-11, explaining this embodiment, this embodiment discloses a chain bucket type unloading and cleaning integrated equipment, the door frame 1 is equipped with a first conveying mechanism 8, the first conveying mechanism 8 is a belt conveyor, which is used to convey the bulk materials after being scooped out by the chain bucket mechanism 4, and a drop hopper 29 is installed at the end of the first conveying mechanism 8. The bulk materials conveyed by the first conveying mechanism 8 fall into the designated unloading area through the drop hopper 29. Specific implementation method three:

[0080] In conjunction with the instructions Figures 1-11 , and on the basis of the second specific embodiment, a chain bucket type unloading and cleaning integrated device in this embodiment further includes a second conveying mechanism 9, one end of which is hinged on the door frame 1, and a lifting rope 10 is installed on the door frame 1, and the lifting rope 10 is connected to the other end of the second conveying mechanism 9. The second conveying mechanism 9 is a belt conveyor. With this arrangement, the second conveying mechanism 9 can be unfolded and folded under the action of the lifting rope 10. When the entire device stops operating, the lifting rope 10 drives the second conveying mechanism 9 to fold and store. When the device is working, one end of the second conveying mechanism 9 is arranged at the bottom of the drop hopper 29, and the bulk material conveyed by the first conveying mechanism 8 falls into the second conveying mechanism 9 through the drop hopper 29. The second conveying mechanism 9 conveys the bulk material to a place away from the chain bucket type unloading and cleaning integrated device, thereby realizing the transfer of materials. Specific implementation method four:

[0082] In conjunction with the instructions Figure 6 、 Figure 12 and Figure 13, explaining this embodiment, a chain bucket type unloading cleaning integrated device of this embodiment, this embodiment further designs the cleaning mechanism 7, optimizes the running stability of the cleaning mechanism 7, and thus improves the cleaning effect of the cleaning mechanism 7, specifically: the upper end of the scissors frame 11 is mounted on the storage frame 6 through the cylinder frame 30, the scissors frame 11 has a plurality of hinge shafts 31, the cylinder end of the first cylinder 15 is also mounted on the cylinder frame 30, the output end of the first cylinder 15 is installed with a scissors frame support mechanism 32, the scissors frame support mechanism 32 includes a support mounting seat plate 33 and a support mounting seat plate The first chute 34 on the support and mounting base plate 33 has one end mounted on the output shaft of the first oil cylinder 15, and the other end of the support and mounting base plate 33 is fixedly mounted to one of the hinge shafts 31 at the center of the scissors frame 11. When the scissors frame 11 needs to be deployed, the output shaft of the first oil cylinder 15 extends and pushes the hinge shaft 31 at the center of the scissors frame 11 through the support and mounting base plate 33, thereby deploying the scissors frame 11. When the scissors frame 11 needs to be retracted, the output shaft of the first oil cylinder 15 retracts, and the hinge shaft 31 at the center of the scissors frame 11 sequentially slides into the first chute 34. In this embodiment, the first chute 34 can ensure the smooth landing and smooth recovery of the scissors frame 11. During use, it is required to ensure that when the scissors frame 11 is deployed, at least two hinge shafts 31 on the scissors frame 11 are in the first chute 34. This arrangement allows the hinge shaft 31 to be clamped by the first chute 34 of the scissor frame support mechanism 32, thereby improving the stability of the scissor frame 11 during operation, preventing the shaking and vibration of the scissor frame 11 from being transmitted to the cleaning mechanism 7. This ensures that the cleaning mechanism 7 operates stably when in operation, preventing the cleaning brush from not fully contacting the inner wall of the truck to be dumped due to vibration, resulting in incomplete cleaning. Therefore, under the action of the scissor frame support mechanism 32, the working stability of the cleaning mechanism 7 is improved, and the cleaning effect is improved. Specific implementation method five:

[0084] In conjunction with the instructions Figure 7 and Figure 8This embodiment describes a chain bucket truck unloading cleaning device. Guide baffles 35 are installed on both sides of the bottom of the scraper housing 16. The guide baffles 35 are larger than the corner brushes 26. With this arrangement, when cleaning the inner sidewall of the truck to be dumped, the vertical brush 24 is used to clean the bulk material attached to the inner sidewall of the truck to be dumped. The cleaned bulk material falls due to gravity, and the corner brushes 26 are then used to clean the bulk material and sweep it into the working area of ​​the scraper 21. Without the cooperation of the guide baffles 35, the bulk material cleaned by the corner brushes 26 would splash everywhere, failing to gather and collect the bulk material. However, with the cooperation of the guide baffles 35 and the corner brushes 26, the bulk material can be gathered and collected into the working area of ​​the scraper 21, making it easier for the scraper 21 to lift the bulk material and ultimately eject it through the material ejection port 22. Specific implementation method six:

[0086] In conjunction with the instructions Figure 14 and Figure 15 The present embodiment is described below. This embodiment is a chain bucket type truck unloading and cleaning integrated device. The scraper housing 16 includes a rear wall panel 36, side panels 37, and a sprocket mounting box 38. Side panels 37 are mounted on both sides of the rear wall panel 36. The top of the side panels 37 forms a material discharge port 22. Two sprocket mounting boxes 38 are mounted on the rear wall panel 36. The sprocket mounting boxes 38 are welded together from three vertical panels, which form a receiving cavity. The active scraper sprocket 18 and the driven scraper sprocket 19 are both mounted within the sprocket mounting boxes 38. This arrangement, in which the sprocket mounting boxes 38 of the scraper housing 16 are welded together from three vertical panels, which form a receiving cavity, not only improves the structural strength of the scraper housing 16, but also provides a closed and clean working environment for the sprocket rotation, preventing bulk material from entering the sprocket and chain, causing transmission failure and affecting the operation of the scraper mechanism. In addition, the structural design of the sprocket mounting box 38 and the scissor frame support mechanism 32 works together to further improve the working stability of the cleaning mechanism 7, thereby indirectly improving the cleaning effect. Specific implementation method seven:

[0088] In conjunction with the instructions Figure 6 、 Figure 16-19This embodiment describes a chain bucket type truck unloading and cleaning device, further comprising a bucket lift scraper 39 fixedly mounted on either side of the chain bucket mechanism 4 via connecting arms 40. The bucket lift scraper 39 comprises an upper positioning post 41 and a lower bracket 42, while the scraper housing 16 comprises a positioning seat 43 and a positioning support frame 44. Thus, the bucket lift scraper 39 is positioned between the chain bucket mechanism 4 and the cleaning mechanism 7. During the unloading and cleaning operation, the bucket lift scraper 39 is used to scrape off any remaining bulk material from the bottom of the truck being unloaded. Furthermore, the bucket lift scraper 39 and the chain bucket mechanism 4 enclose a space for the hopper 27 to scoop out material. The bucket lift scraper 39 can gather bulk material within this space, allowing the hopper 27 in the chain bucket mechanism 4 to fully scoop out the material within this space (maximum filling of the hopper 27), thereby improving the efficiency of the chain bucket mechanism 4. On the other hand, the bucket scraper plate 39 and the cleaning mechanism 7 also enclose a cleaning space. The materials on the side wall of the truck to be unloaded after being cleaned by the vertical brush mechanism 14 can fall into the working space of the corner brush 26 of the vertical brush mechanism 14 under the cover of the bucket scraper plate 39, avoiding the splashing of materials after cleaning by the vertical brush mechanism 14 and causing pollution to the cleaned area. On the other hand, the scraper plate 39 has an upper positioning column 41 and a lower bracket 42. When performing unloading and cleaning operations, the scraper mechanism 13 of the cleaning mechanism 7 is positioned on the upper positioning column 41 and the lower bracket 42. Specifically, when the cleaning mechanism 7 descends, the positioning seat 43 on the scraper shell 16 (the positioning seat 43 is processed with a positioning hole) is positioned on the upper positioning column 41, and the positioning support frame 44 on the scraper shell 16 is positioned and installed on the lower bracket 42. In this way, when the cleaning mechanism 7 is running, the bucket scraper plate 39 provides a stable working platform (working bracket) for the cleaning mechanism 7 to avoid shaking during operation of the cleaning mechanism 7, which affects the cleaning effect. In addition, the bucket scraper plate 39, the scraper shell 16 and the scissors frame support mechanism 32 work together to provide an effective and stable working environment for the cleaning mechanism 7, improve the working stability of the cleaning mechanism 7, and indirectly improve the cleaning effect. Specific implementation method eight:

[0090] In conjunction with the instructions Figure 5 、 Figure 16 、 Figure 17 、 Figure 20-24, which illustrates this embodiment, a chain bucket type truck unloading and cleaning integrated device according to this embodiment further includes an auxiliary collection baffle assembly 45, which is slidably mounted in the storage frame 6. The auxiliary collection baffle assembly 45 includes an outer frame 46, an inner frame 47, and a shovel plate 48. The outer frame 46 is slidably mounted in the storage frame 6, and the outer frame 46 is connected to the storage frame 6 via a first lifting cylinder 49. The inner frame 47 is slidably mounted in the outer frame 46, and the inner frame 47 is connected to the outer frame 46 via a second lifting cylinder 50. The shovel plate 48 is hingedly mounted at the bottom of the inner frame 47. A rotating cylinder 51 is also mounted on the inner frame 47 and the shovel plate 48. With such arrangement, at the end stage of the synchronous unloading and cleaning operation, due to the right-angled corner at the bottom of the truck (carriage) to be unloaded, the bulk materials (coal) at the corner of the truck (carriage) to be unloaded are accumulated, resulting in the problem of being unable to be completely unloaded. The auxiliary collection baffle assembly 45 of this embodiment can cooperate with the chain bucket mechanism 4 and the cleaning mechanism 7 to remove the remaining bulk materials at the corner. The specific method is: when the chain bucket mechanism 4 moves to the corner area, the first lifting cylinder 49 pushes the outer frame 46 out of the storage frame 6, and the second lifting cylinder 50 pushes the inner frame 47 out of the outer frame 46. The shovel plate 48 is close to the inner wall of the truck to be unloaded and falls in a vertical direction. Figure 24 and Figure 25 As shown, until the bottom surface of the shovel plate 48 contacts the bottom surface of the truck to be unloaded, the rotary cylinder 51 is activated, and the rotary cylinder 51 drives the shovel plate 48 to rotate relative to the inner frame 47, scooping up the material 52 at the right-angled corner of the bottom of the truck to be unloaded. The scooped material 52 is collected by the hopper of the chain bucket mechanism 4 to complete the unloading operation. The auxiliary collection baffle assembly 45 can completely remove the bulk materials accumulated in the corners of the car body, reducing the labor intensity of manual unloading and avoiding a harsh working environment. In addition, the auxiliary collection baffle assembly 45 is installed in a sliding manner in the outer frame 46 in a synchronous state during the unloading operation to assist in digging / excavating the accumulated materials in the corners, overcoming the problem that the unloading process may temporarily stop, resulting in reduced production efficiency, improving working efficiency, and reducing unloading costs for users. Specific implementation method nine:

[0092] In conjunction with the instructions Figure 1-Figure 25 , explaining this embodiment, a chain bucket type unloading vehicle cleaning method disclosed in this embodiment is implemented based on a chain bucket type unloading vehicle cleaning integrated device, comprising the following steps:

[0093] Step S1, control the gantry 1 to move to the end of the truck to be unloaded, and adjust the position of the chain bucket lifting and reclaiming mechanism 2 on the gantry 1 so that the lifting and reclaiming mechanism 2 is directly above the truck to be unloaded;

[0094] Step S2, controlling the chain bucket mechanism 4 in the chain bucket lifting and reclaiming mechanism 2 to fall, so that the hopper 27 in the chain bucket mechanism 4 digs the bulk material from one end of the truck to be unloaded until the bulk material at the end of the truck to be unloaded is emptied;

[0095] Step S3: Control the gantry 1 to move so that the bulk materials dug by the chain bucket mechanism 4 can leave working space for the cleaning mechanism 7;

[0096] Step S4: Extend the cleaning mechanism 7 from the storage frame 6, and make the vertical brush mechanism 14 of the cleaning mechanism 7 fit on the inner wall of the end of the truck to be unloaded;

[0097] Step S5, start the cleaning mechanism 7, the vertical brush mechanism 14 of the cleaning mechanism 7 rotates to clean the inner wall of the truck to be unloaded, and cleans the bulk materials remaining on the inner wall to the bottom of the truck to be unloaded. At the same time, start the scraper mechanism 13, and the scraper mechanism 13 lifts the cleaned bulk materials through the reciprocating scraper 21 and throws them into the working area of ​​the chain bucket mechanism 4 through the material throwing port 22, and unloads the materials onto the first conveying mechanism 8 as the chain bucket mechanism 4 is in the working state.

[0098] The process also includes step S6, controlling the gantry 1 to drive the chain bucket mechanism 4 and the cleaning mechanism 7 to move smoothly toward the other end of the truck to be unloaded. When the chain bucket mechanism 4 moves to the corner area, the first lifting cylinder 49 pushes the outer frame 46 out of the storage frame 6, and the second lifting cylinder 50 pushes the inner frame 47 out of the outer frame 46. The shovel plate 48 approaches the inner wall of the truck to be unloaded and falls vertically. Figure 23 and Figure 24 As shown, until the bottom surface of the shovel plate 48 contacts the bottom surface of the truck to be unloaded, the rotating cylinder 51 is actuated, and the rotating cylinder 51 drives the shovel plate 48 to rotate relative to the inner frame 47, scooping up the material 52 at the right-angle corner of the bottom of the truck to be unloaded. The scooped material 52 is collected by the hopper of the chain bucket mechanism 4 to complete the unloading operation.

[0099] In this embodiment, the number of chain buckets installed in the chain bucket mechanism 4 is 40-60, and the volume of the chain bucket is 0.3-1.0 (m 3 ), the chain bucket will grab the coal or other bulk materials in the car through movement and gradually move to the unloading position. Take the C70XY general-purpose open car as an example. The load capacity of the open car is 70 tons and the volume is 77 (m 3 ), the chain bucket unloader using the unloading method of this embodiment has a working efficiency of: unloading 200-500 tons per hour (t / h), and can unload about 5 to 8 open wagons per hour, while solving the problem of manual clearing operations. Specific implementation method ten:

[0101] In conjunction with the instructions Figure 1-Figure 25, explaining this embodiment, a chain bucket type unloading vehicle cleaning method disclosed in this embodiment is implemented based on a chain bucket type unloading vehicle cleaning integrated device, comprising the following steps:

[0102] Step 1: Control the gantry 1 to move to the end of the truck to be unloaded, and adjust the position of the chain bucket lifting and reclaiming mechanism 2 on the gantry 1 so that the lifting and reclaiming mechanism 2 is directly above the truck to be unloaded;

[0103] Step 2: Control the chain bucket mechanism 4 in the lifting and reclaiming mechanism 2 to fall. The hopper 27 in the chain bucket mechanism 4 starts from one end of the truck to be unloaded. Figure 25 As shown, the bulk materials are dug out layer by layer until the last layer of bulk materials is dug out, and the cleaning mechanism 7 extends from the storage frame 6 and makes the vertical brush mechanism 14 of the cleaning mechanism 7 fit the inner wall of the end of the truck to be unloaded; the bulk materials in the truck to be unloaded are divided into 3-5 layers and unloaded layer by layer according to the capacity of the truck to be unloaded;

[0104] Step 3: Start the cleaning mechanism 7. The vertical brush mechanism 14 of the cleaning mechanism 7 rotates to clean the inner wall of the truck to be unloaded, and cleans the bulk materials remaining on the inner wall to the bottom of the truck to be unloaded. At the same time, start the scraper mechanism 13. The scraper mechanism 13 lifts the cleaned bulk materials through the reciprocating scraper 21 and throws them into the working area of ​​the chain bucket mechanism 4 through the material throwing port 22. As the chain bucket mechanism 4 is in the working state, the materials are unloaded onto the first conveying mechanism 8.

[0105] The process also includes step 4, controlling the gantry 1 to drive the chain bucket mechanism 4 and the cleaning mechanism 7 to move smoothly toward the other end of the truck to be unloaded. When the chain bucket mechanism 4 moves to the corner area, the first lifting cylinder 49 pushes the outer frame 46 out of the storage frame 6, and the second lifting cylinder 50 pushes the inner frame 47 out of the outer frame 46. The shovel plate 48 approaches the inner wall of the truck to be unloaded and falls vertically. Figure 24 and Figure 25 As shown, until the bottom surface of the shovel plate 48 contacts the bottom surface of the truck to be unloaded, the rotating cylinder 51 is actuated, and the rotating cylinder 51 drives the shovel plate 48 to rotate relative to the inner frame 47, scooping up the material 52 at the right-angle corner of the bottom of the truck to be unloaded. The scooped material 52 is collected by the hopper of the chain bucket mechanism 4 to complete the unloading operation.

[0106] In this embodiment, the bulk materials in the truck are unloaded layer by layer. During the unloading process, the bulk materials in the truck to be unloaded are divided into 3-5 layers according to the capacity of the truck to be unloaded in step 2 and unloaded layer by layer. The unloading thickness decreases layer by layer to reduce the workload of the last layer (unloading and cleaning workload). The unloading method of this embodiment has the following advantages:

[0107] 1. Layer-by-layer unloading can more accurately control the amount of material discharged at each layer, avoiding overflow or waste caused by unloading too quickly or too violently during the unloading process;

[0108] 2. For some fragile or easily damaged materials (such as granular materials), unloading layer by layer can reduce the impact force and avoid excessive impact or damage to the materials caused by one-time unloading;

[0109] 3. Layer-by-layer unloading helps ensure uniformity of materials during unloading, avoiding uneven accumulation of materials in the carriage, which may cause unloading difficulties or require additional cleaning;

[0110] 4. When the material is relatively loose, unloading it all at once may cause collapse or accumulation. Unloading it layer by layer can avoid this situation and improve the smoothness of unloading. When collapse or accumulation occurs when unloading it all at once, the collapsed and accumulated materials will overflow into the working area of ​​the cleaning mechanism 7, causing the workload of the cleaning mechanism 7 to increase, which violates the original intention of the cleaning mechanism 7 as a cleaning task, resulting in reduced cleaning efficiency and a decline in cleaning effect. Unloading it layer by layer can solve the above problem.

[0111] 5. Layer-by-layer unloading helps operators better control the unloading process and reduce safety hazards caused by hasty or uneven unloading;

[0112] 6. Finally, layer-by-layer unloading can reduce the flying or scattering of materials during the unloading process, thereby reducing environmental pollution on site and keeping the work area clean.

[0113] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are protected by the present invention.
