Description

[0003] At present, chain bucket unloading machine is generally used to unload materials from railway open wagon.The traditional unloading method is that bucket elevator is lowered into the open wagon to be unloaded, and the material is lifted to a certain height by reciprocating chain bucket, and then poured into the unloading hopper, and finally leaked into the conveying belt machine to realize unloading operation.For example: the announcement number CN215923808U, a kind of unloading machine, the unloading machine includes door-shaped support and lifting frame installed on the door-shaped support, motor is installed on the lifting frame, transmission sprocket is installed on the motor, chain is installed on the transmission sprocket, chain bucket is fixed on the chain, forming chain bucket unloading machine.The unloading machine realizes unloading operation on the material in the wagon through the reciprocating movement of chain bucket.But in the actual unloading process, due to the large turning radius of reciprocating chain bucket, the bucket elevator unloads the material in the open wagon to be unloaded, and there is a cleaning dead angle between the bucket elevator and the inner wall of the open wagon to be unloaded (a circular arc angle is formed between the inner wall and the chain bucket during the turning process after the chain bucket picks up the material, and the vertical angle is formed between the side wall of the open wagon and the bottom, so the area formed by the circular arc angle and the vertical angle accumulates the material that cannot be picked up by the chain bucket, which is called cleaning dead angle), which leads to incomplete cleaning of the material in the bucket elevator.Artificial cleaning is needed, which is labor-intensive on the one hand, and time-consuming and laborious on the other hand, resulting in low unloading efficiency.

[0066] In this embodiment, the working principle of a chain bucket unloading sweeper is as follows:

[0067] With the example of synchronous operation of train open car (coal) unloading and cleaning, the train open car enters the unloading area and stays, first, the portal 1 is controlled to walk to the end of the unloading car to be cleaned, and the position of the chain bucket lifting and taking material mechanism 2 on the portal 1 is adjusted, so that the lifting and taking material mechanism 2 is above the unloading car to be cleaned; secondly, the chain bucket mechanism 4 in the chain bucket lifting and taking material mechanism 2 is controlled to fall, the hopper 27 in the chain bucket mechanism 4 digs into the bulk material from one end of the unloading car to be cleaned, until the bulk material at the end of the unloading car to be cleaned is dug out; thirdly, the portal 1 is controlled to travel a distance, so that the bulk material dug by the chain bucket mechanism 4 can leave a working space for the cleaning mechanism 7; fourthly, the cleaning mechanism 7 is stretched out 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 unloading car to be cleaned; finally, the cleaning mechanism 7 is started, the vertical brush mechanism 14 of the cleaning mechanism 7 rotates to clean the inner wall of the unloading car to be cleaned, and the bulk material remaining on the inner wall is cleaned to the bottom of the unloading car to be cleaned, at the same time, the scraper mechanism 13 is started, the bulk material after cleaning is lifted by the reciprocating scraper 21 and thrown into the working area of the chain bucket mechanism 4 through the material throwing port 22, and the material is unloaded to the first conveying mechanism 8 along with the working state of the chain bucket mechanism 4.

[0068] In this embodiment, in the train coal unloading operation, the chain bucket unloading machine with cleaning function can realize synchronous unloading and cleaning, which fully guarantees the positive role of industrial and mining enterprises in improving work efficiency, reducing cost, and ensuring safety, and has the following advantages:

[0069] 1. Improve work efficiency, synchronous unloading and cleaning can greatly improve work efficiency. Compared with the traditional unloading, the traditional operation usually unloads coal first and then cleans, which will cause time waste, especially in the case of large amount of coal unloading. Using the self-cleaning function of the chain bucket unloading machine, the cleaning can be carried out at the same time as the unloading, which not only reduces the idle time, but also avoids the situation of stopping due to cleaning. In addition, the continuity and efficiency of the operation make the total time of each round of coal unloading operation shortened, improving the overall production efficiency.

[0070] 2. Reduce labor cost, the synchronous unloading and cleaning operation mode greatly reduces the need for manual intervention. In the traditional unloading mode, after unloading coal, manual intervention is often needed for cleaning, which increases the consumption of human resources. The chain bucket unloading machine with self-cleaning function can realize automatic cleaning, avoiding repeated hiring of cleaning personnel or additional arrangement of cleaning operation after unloading coal, which significantly reduces the labor cost.

[0071] 3. Enhancing safety during operations, coal residue, coal fines, and dust often fall onto the tracks or the work area during the unloading process. If not cleaned up promptly, these substances can cause workers to slip or equipment to malfunction. Synchronized cleaning can effectively reduce these falling objects and reduce the risk of accidents caused by uneven ground or accumulated coal fines. At the same time, it can keep the work site clean and ensure a safe working environment.

[0072] 4. Improving the cleanliness of the work environment, the cleaning function can clean the work site in real time during the unloading process, avoiding the accumulation of coal dust, coal residue, and other waste on the ground or surrounding area, thus maintaining the cleanliness of the work site. This not only improves the working environment for workers, but also enhances the image of the enterprise, especially in some enterprises that emphasize environmental protection and site cleanliness, the application of the cleaning function is crucial.

[0073] 5. Reducing downtime, in traditional unloading operations, unloading and cleaning need to be performed separately, often resulting in idle downtime. In particular, during the cleaning process, unloading may be temporarily halted, resulting in reduced production efficiency. The self-cleaning function of the chain bucket unloader can simultaneously perform unloading and cleaning, minimizing idle time and improving the continuity and efficiency of operations.

[0074] 6. Through the self-cleaning function of the chain bucket unloader, the configuration of equipment and personnel can be optimized. Tasks that originally required multiple devices and more manual operations can now be completed by one device and one operator. This not only improves resource utilization, but also makes the operation process more concise and efficient, reducing unnecessary resource waste and lowering operating costs.

[0075] 7. Enhancing automation level, the application of the self-cleaning function of the chain bucket unloader improves the automation level of the entire unloading process. Through automated cleaning, the human involvement is reduced, improving the intelligent level of the operation process. The improvement of automation not only reduces errors caused by human factors, but also reduces the work intensity of operators, making the operation safer and more accurate.

[0076] 8. Improving overall operational efficiency, in summary, the application of the self-cleaning function of the chain bucket unloader makes the entire unloading process more efficient, energy-saving, environmentally friendly, and safe. By reducing unnecessary operation steps and lowering operating costs, enterprises can significantly improve their overall operational efficiency. In long-term operations, this advantage will be more pronounced, especially in large-scale unloading operations, which can save enterprises a lot of manpower, material resources, and time costs.

In this way, the second conveying mechanism 9 can be unfolded and folded under the action of the lifting rope 10, when the whole device stops working, the lifting rope 10 drives the second conveying mechanism 9 to be folded and stored, and when the device works, one end of the second conveying mechanism 9 is arranged at the bottom of the falling hopper 29, the bulk materials conveyed by the first conveying mechanism 8 fall into the second conveying mechanism 9 through the falling hopper 29, and the second conveying mechanism 9 conveys the bulk materials to a position far away from the chain bucket unloading and cleaning integrated device, so that the bulk materials are transferred. Specific embodiment four:

[0082] The drawings are combined with the description Figure 12 , Figure 13 and Figure 7, it is illustrated that the chain bucket unloading cleaning machine of the embodiment, the cleaning mechanism 7 of the embodiment is further designed, the operation stability of the cleaning mechanism 7 is optimized, and then the cleaning effect of the cleaning mechanism 7 is improved, and specifically, the upper end of the scissor frame 11 is installed on the storage frame 6 through the oil cylinder frame 30, a plurality of hinged shafts 31 are arranged on the scissor frame 11, the cylinder end of the first oil cylinder 15 is also installed on the oil cylinder frame 30, the output end of the first oil cylinder 15 is provided with a scissor frame supporting mechanism 32, the scissor frame supporting mechanism 32 comprises a supporting mounting seat plate 33 and a first sliding groove 34 arranged on the supporting mounting seat plate 33, one end of the supporting mounting seat plate 33 is installed on the output shaft of the first oil cylinder 15, the other end of the supporting mounting seat plate 33 is fixedly installed with one of the hinged shafts 31 at the center of the scissor frame 11, when the scissor frame 11 needs to be unfolded, the output shaft of the first oil cylinder 15 is stretched out, the output shaft of the first oil cylinder 15 pushes the hinged shaft 31 at the center of the scissor frame 11 through the supporting mounting seat plate 33, so that the scissor frame 11 is unfolded, when the scissor frame 11 needs to be retracted, the output shaft of the first oil cylinder 15 is retracted, and the hinged shaft 31 at the center of the scissor frame 11 is sequentially slid into the first sliding groove 34. In the embodiment, the first sliding groove 34 can ensure that the scissor frame 11 is stably landed and stably recovered, and at least two hinged shafts 31 on the scissor frame 11 are required to be in the first sliding groove 34 when the scissor frame 11 is required to be unfolded during use. By clamping the hinged shaft 31 through the first sliding groove 34 of the scissor frame supporting mechanism 32, the stability of the scissor frame 11 during operation is improved, and the shaking and shaking of the scissor frame 11 are avoided to be transmitted to the cleaning mechanism 7, so that the cleaning mechanism 7 is stable during operation, and the cleaning brush cannot completely contact the inner side wall of the vehicle to be dumped due to shaking, so that the cleaning is not complete. Therefore, under the action of the scissor frame supporting mechanism 32, the working stability of the cleaning mechanism 7 is improved, and the cleaning effect is improved.

At this time, the corner brush 26 is used for cleaning the bulk materials and cleaning them into the working area of the scraper 21. If the cooperation of the guide material baffle 35 is not used, the bulk materials cleaned by the corner brush 26 will splash everywhere, and the bulk materials cannot be collected. However, by using the cooperation of the guide material baffle 35 and the corner brush 26, the bulk materials can be collected into the working area of the scraper 21, the scraper 21 can conveniently lift the bulk materials, and finally the bulk materials are thrown out through the material throwing port 22.

In this way, the bucket lifting and scraping plate 39 is arranged between the chain bucket mechanism 4 and the cleaning mechanism 7. When the unloading and cleaning operation is performed, on the one hand, the bucket lifting and scraping plate 39 is used to scrape the remaining bulk material on the bottom of the vehicle to be unloaded and cleaned. On the other hand, the bucket lifting and scraping plate 39 forms a space with the chain bucket mechanism 4 for the bucket 27 to pick up, and the bucket lifting and scraping plate 39 can gather the bulk material in the space, so that the bucket 27 in the chain bucket mechanism 4 can fully pick up the material in the space (the material can be as full as possible in the bucket 27), thereby improving the working efficiency of the chain bucket mechanism 4. On the other hand, the bucket lifting and scraping plate 39 also forms a cleaning space with the cleaning mechanism 7. The material on the sidewall of the vehicle to be unloaded and cleaned 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 shielding of the bucket lifting and scraping plate 39, thereby avoiding the splashing of the material after being cleaned by the vertical brush mechanism 14 to pollute the cleaned area. On the other hand, the bucket lifting and scraping plate 39 has the upper positioning column 41 and the lower bracket 42. When the unloading and cleaning operation is performed, the scraping plate 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 is lowered, the upper positioning seat 43 (a positioning hole is formed in the positioning seat 43) of the scraping plate shell 16 is positioned on the upper positioning column 41, and the positioning support frame 44 on the scraping plate shell 16 is positioned and installed on the lower bracket 42. In this way, when the cleaning mechanism 7 operates, the bucket lifting and scraping plate 39 provides a stable working platform (a working support) for the cleaning mechanism 7, thereby avoiding the shaking of the cleaning mechanism 7 during operation and affecting the cleaning effect. In addition, the bucket lifting and scraping plate 39, the scraping plate shell 16 and the scissor support mechanism 32 jointly provide an effective and stable working environment for the cleaning mechanism 7, thereby improving the working stability of the cleaning mechanism 7 and indirectly improving the cleaning effect. DETAILED DESCRIPTION

[0090] The drawings illustrating the specific embodiments of the present application are attached herewith Figure 16 , Figure 17 , Figures 20-24 , Figure 24As shown, the chain bucket unloading and cleaning machine of the embodiment further comprises an auxiliary collection baffle assembly 45 which is slidingly installed in the storage frame 6. The auxiliary collection baffle assembly 45 comprises an outer frame 46, an inner frame 47 and a shovel plate 48. The outer frame 46 is slidingly installed in the storage frame 6 and is connected and installed with the storage frame 6 by a first lifting oil cylinder 49. The inner frame 47 is slidingly installed in the outer frame 46 and is connected and installed with the outer frame 46 by a second lifting oil cylinder 50. The shovel plate 48 is hingedly installed at the bottom of the inner frame 47, and the inner frame 47 and the shovel plate 48 are further provided with a rotating oil cylinder 51. In this way, at the end of the synchronous operation of unloading and cleaning, due to the existence of the right-angle corner at the bottom of the unloading and cleaning vehicle (carriage), the bulk material (coal) at the corner of the unloading and cleaning vehicle (carriage) is accumulated, causing the unloading and cleaning to be incomplete. The auxiliary collection baffle assembly 45 of the embodiment can cooperate with the chain bucket mechanism 4 and the cleaning mechanism 7 to remove the remaining bulk material at the corner. Specifically, when the chain bucket mechanism 4 travels to the corner area, the first lifting oil cylinder 49 pushes the outer frame 46 out of the storage frame 6, the second lifting oil cylinder 50 pushes the inner frame 47 out of the outer frame 46, and the shovel plate 48 is close to the inner wall of the unloading and cleaning vehicle and falls vertically, as shown in Figure 25 and Figures 1-25 shown, until the bottom surface of the shovel plate 48 contacts the bottom surface of the unloading and cleaning vehicle. At this time, the rotating oil cylinder 51 acts, and the rotating oil cylinder 51 drives the shovel plate 48 to rotate relative to the inner frame 47, and the material 52 at the right-angle corner at the bottom of the unloading and cleaning vehicle is scooped up. The scooped-up material 52 is collected by the hopper of the chain bucket mechanism 4 to complete the unloading and cleaning operation. The auxiliary collection baffle assembly 45 can completely remove the bulk material accumulated at the corner of the carriage, reduce the labor intensity of manual unloading and cleaning, avoid the harsh working environment, and further realize the auxiliary digging / picking operation on the accumulated material at the corner in the synchronous state of the unloading and cleaning operation by slidingly installing the auxiliary collection baffle assembly 45 in the outer frame 46. This overcomes the problem that the unloading and cleaning vehicle may temporarily stop during the cleaning process, resulting in a reduction in production efficiency, improves the operation efficiency, and reduces the unloading and cleaning cost for the user.

Specific implementation ten

[0101] In combination with the drawings in the specification Figure 25The chain bucket unloading and cleaning method disclosed in the embodiment is realized based on a chain bucket unloading and cleaning machine, and includes the following steps.

[0102] Step one: control the portal frame 1 to travel to the end of the unloading truck to be cleaned, and adjust the position of the chain bucket lifting and taking mechanism 2 on the portal frame 1, so that the lifting and taking mechanism 2 is above the unloading truck to be cleaned.

[0103] Step two: control the chain bucket mechanism 4 in the lifting and taking mechanism 2 to fall, and the hoppers 27 in the chain bucket mechanism 4 start to dig and take the bulk material from one end of the unloading truck to be cleaned, and gradually dig and take the bulk material layer by layer, as shown in Figure 24 , until the last layer of bulk material is taken, 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 unloading truck to be cleaned; according to the capacity of the unloading truck to be cleaned, the bulk material in the unloading truck to be cleaned is divided into 3-5 layers for cleaning and unloading layer by layer.

[0104] Step three: start the cleaning mechanism 7, the vertical brush mechanism 14 of the cleaning mechanism 7 rotates to clean the inner wall of the unloading truck to be cleaned, and the bulk material remaining on the inner wall is cleaned to the bottom of the unloading truck to be cleaned, at the same time, the scraper mechanism 13 is started, the bulk material cleaned is lifted by the reciprocating scraper 21 and thrown into the working area of the chain bucket mechanism 4 through the material throwing port 22, and the bulk material is unloaded onto the first conveying mechanism 8 along with the working state of the chain bucket mechanism 4.

[0105] Step four: control the portal frame 1 to stably drive the chain bucket mechanism 4 and the cleaning mechanism 7 to travel to the other end of the unloading truck to be cleaned, when the chain bucket mechanism 4 travels to the corner area, the outer frame 46 is pushed out of the storage frame 6 by the first lifting oil cylinder 49, the inner frame 47 is pushed out of the outer frame 46 by the second lifting oil cylinder 50, the shovel plate 48 is close to the inner wall of the unloading truck to be cleaned and falls vertically, as shown in Figure 25 and ​ , until the bottom surface of the shovel plate 48 contacts the bottom surface of the unloading truck to be cleaned, at this time, the rotating oil cylinder 51 is actuated, the rotating oil cylinder 51 drives the shovel plate 48 to rotate relative to the inner frame 47, the bulk material 52 at the right-angle corner of the bottom of the unloading truck to be cleaned is scooped up, and the scooped-up bulk material 52 is collected by the hopper of the chain bucket mechanism 4 to complete the unloading work.

[0106] In the embodiment, the bulk material in the unloading truck is unloaded in the form of layer-by-layer unloading, in the unloading process, the capacity of the unloading truck to be cleaned in step two is divided into 3-5 layers for layer-by-layer unloading, and the thickness of unloading is gradually decreased layer by layer to reduce the workload of the last layer (unloading and cleaning workload); the unloading method of the embodiment has the following advantages:

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

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

[0109] 3. Layer-by-layer unloading helps to ensure the uniformity of the material during unloading, avoiding uneven accumulation of the material in the car, which leads to difficult unloading or the need for additional cleaning;

[0110] 4. When the material is relatively loose, one-time unloading may cause collapse and accumulation, and layer-by-layer unloading can avoid this situation and improve the smoothness of unloading. When one-time unloading is used and collapse and accumulation occur, the collapsed and accumulated material will overflow to the working area of the cleaning mechanism 7, increasing the workload of the cleaning mechanism 7, which is contrary to the original intention of the cleaning mechanism 7, resulting in reduced unloading efficiency and decreased cleaning effect. Layer-by-layer unloading can solve the above problems;

[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 unloading, thereby reducing environmental pollution on site and maintaining the cleanliness of the work area.

Those skilled in the art can make many forms under the inspiration of the present application without departing from the purpose of the present application and the scope protected by the claims, and these are all within the protection of the present application.
