Description

Technical Field

[0001] The utility model relates to the technical field of material cleaning in sintering production, in particular to an automatic material cleaning trolley. Background Art

[0002] The sintering batching area is an indispensable part of the entire sintering production line, and is directly related to the production capacity and product quality of the entire sintering production line. In this area, the batching belt head is a key part connecting the drum mixer and the batching belt conveyor. It not only accurately transports the raw materials from the batching belt conveyor to the drum mixer, but also ensures the continuity and stability of the material flow during this process. However, a common problem in the existing technology is that due to the certain gap between the belt and the drum mixer and the fact that this area is not a closed space environment, a certain amount of dust and falling materials will occur when the belt conveyor feeds the materials into the drum.

[0003] This dust not only pollutes the production environment and affects employee health, but also increases the difficulty and cost of equipment maintenance. The problem of material droplets is even more serious. Most of the material tends to accumulate directly below the belt. Long-term accumulation can affect the normal operation of the belt conveyor, wear the bottom rollers, and shorten the equipment's service life. Excessive material accumulation can also pose safety hazards such as equipment failure and extended downtime. Furthermore, the confined space at the drop point creates numerous inconveniences for workers during daily operations, including difficult cleaning and numerous blind spots in monitoring. These factors significantly increase the risk factor of production operations. Utility Model Content

[0004] The utility model aims to provide an automatic material-clearing trolley, which can solve the problem of difficulty in clearing materials when the existing batching belt machine head is lowered and dropped.

[0005] The lifting of the ...

[0006] In the technical solution of the automatic material cleaning trolley, a more specific technical solution may be: side blocking wheels that roll on the side of the guide rail are further installed on both sides of the trolley frame.

[0007] In some possible implementation schemes, a pusher scraper limiting structure is provided in the trolley frame.

[0008] In some possible implementation schemes, the pusher scraper is made of polymer material.

[0009] In some possible implementation schemes, the push scraper is made of polyurethane material.

[0010] In some possible implementation schemes, two sets of the support wheels and the side blocking wheels are installed on the outer side of each side plate.

[0011] In some possible implementation schemes, the power machine uses an electro-hydraulic push rod with a motor.

[0012] In some possible implementation schemes, the control end of the motor is connected to a controller, and the controller is wirelessly connected to a remote control terminal.

[0013] Due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0014] 1. This automatic material cleaning trolley is deployed under the head of the batching belt conveyor. Its compact and flexible structure makes it easy to fit into various narrow spaces. By setting a springboard and guide rails that extend into the drum mixer, the trolley with a pusher scraper is driven by a power machine to reciprocate on the guide rails, so that the pusher scraper can scrape the accumulated material on the springboard into the drum mixer, which can effectively clean the material, improve the cleaning efficiency, and significantly reduce material accumulation. The multiple spaced pusher scrapers configured inside the trolley adopt zoned cleaning, which reduces the load borne by each pusher scraper individually. The cleaning resistance of the trolley is smaller, ensuring that the cleaning process is both meticulous and comprehensive. The close sliding fit between the pusher scraper and the springboard surface greatly improves the scraping and collection efficiency, and the dispersed layout of the pusher scrapers reduces the force on each individual, thereby enhancing the overall cleaning effect. The power machine drives the trolley and pusher scraper to move as a whole, which can withstand greater loads, reduce transportation resistance, and transport more materials.

[0015] 2. Side chocks provide additional lateral support and guidance for the trolley. In complex or uneven working environments, the side chocks can effectively prevent the trolley from tipping over or straying from the intended track, thereby ensuring the trolley's stability and reliability during operation. The contact between the side chocks and the side of the guide rail also acts as a buffer, mitigating impact forces caused by sudden acceleration or deceleration or encountering obstacles, thereby protecting the guide rail from damage and extending the service life of the trolley's structure.

[0016] 3. A pusher scraper limiting structure is set in the trolley frame to ensure that the pusher scraper can maintain an effective cleaning posture during the cleaning process, and avoid the pusher scraper losing effective contact with the surface to be cleaned due to excessive reverse rotation.

[0017] 4. The push scraper is made of polymer materials, especially polyurethane materials, which have excellent wear resistance, usually 3-5 times that of rubber. It can effectively resist the wear of materials and extend the service life. It has high strength, a wide hardness range, can withstand large loads and impact forces, is corrosion-resistant, and can maintain good performance under different working conditions.

[0018] 5. The number of support wheels and side wheels installed can provide more stable support and guidance for the trolley, making the trolley run more smoothly on the guide rail and reducing the additional resistance caused by shaking or deviation. The two work together to greatly enhance the overall stability of the trolley, and can flexibly respond to various working conditions, ensuring that the trolley can run stably under various conditions and improving safety.

[0019] 6. The electro-hydraulic push rod combines the advantages of the electric motor and the hydraulic system, can generate powerful thrust, can easily cope with various heavy loads and complex working conditions, and improve work efficiency and reliability.

[0020] 7. The motor can be started and stopped remotely to reduce direct contact between personnel and equipment and reduce safety risks. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will be further described below in conjunction with the accompanying drawings:

[0026] Figures 1 to 3The automatic material clearing trolley shown mainly includes a trolley body, a power machine, a springboard 8 and a guide rail 9. It is installed below the ingredient belt head 12, wherein the guide rail 9 is installed on the springboard 8, and one end of the springboard 8 and the guide rail 9 is suspended and extends into the cylindrical mixer 13, and has no connection with the cylindrical mixer 13 to avoid hindering the rotation of the cylinder of the cylindrical mixer 13. The trolley body is arranged between the power machine and the cylindrical mixer 13, and the power machine is connected to the trolley body. The trolley body is driven by the power machine to move back and forth on the guide rail 9 to remove accumulated materials.

[0027] like Figure 2 and Figure 3 As shown, the trolley body includes a trolley frame 3, a push scraper 5, support wheels 10 and side wheels 11. The trolley frame 3 is the main structure of the entire trolley, and is composed of two side panels 3-2 and a connecting plate 3-1 connecting one end of the two side panels 3-1, forming a U-shaped structure. The opening between the two side panels 3-2 close to the end of the drum mixer 13 serves as the scraping port of the trolley. The trolley frame 3 is made of No. 4 channel steel to ensure sufficient strength and rigidity. The parallelism of the frame must be strictly aligned to ensure the stability of the trolley during movement. Two sets of support wheels 10 and side wheels 11 are installed on the outside of each side panel 3-2 of the trolley frame 3. The support wheels 10 roll on the upper end surface of the guide rail 9 to ensure the smooth movement of the trolley on the guide rail 9. The side wheels 11 roll on the side of the guide rail 9 to play a positioning and guiding role to prevent the trolley from deviating from the track.

[0028] In some specific embodiments, three spaced-apart pusher scrapers 5 are installed in the trolley frame 3. The surface of the pusher scraper 5 faces the drum mixer 13 in a natural state. The upper end of the pusher scraper 5 is connected to the side plate 3-2 of the trolley frame 3 through the rotating shaft 4, and the lower end is slidably fitted with the surface of the springboard 8. During the movement of the trolley, the pusher scraper 5 can effectively scrape up the accumulated materials and bring them into the drum mixer 13. In addition, a pusher scraper 5 limiting structure is also provided in the trolley frame 3 to ensure the stability and accuracy of the scraper during the scraping process. Specifically, a channel steel 7 serving as a scraper limiting structure is fixed to the side of the rotating shaft 4 near the upper end of the side plate 3-2 of the trolley frame 3. The channel steel 7 is close to the back of the pusher scraper 5. A limiting block 6 matching the channel steel 7 is provided on the pusher scraper 5. The limiting block 6 cooperates with the channel steel 7 to limit the maximum rotation angle of the pusher scraper 5 to no more than 90°. It is worth mentioning that the push scraper 5 is made of polymer material, preferably polyurethane material, which is wear-resistant and not easy to damage.

[0029] In some possible embodiments, the power machine utilizes an electro-hydraulic push rod 1 with a motor, with the recommended model being XDGF1750-1400 / 30. The cylinder of the electro-hydraulic push rod 1 is secured by a mounting bracket 2 and connected to the trolley frame 3 via a connecting rod, driving the trolley's reciprocating motion on the guide rails 9. The motor's control terminal is connected to a controller that wirelessly connects to a remote control terminal, enabling remote start / stop and frequency adjustment. A frequency-modulated motor is recommended to adjust the trolley's movement frequency and speed as needed.

[0030] In some possible embodiments, the guide rail 9 is made of 40° angle steel. Its surface must be smooth and flat to reduce resistance and wear during trolley movement. Furthermore, the guide rail 9 must be larger than the trolley frame 3 to prevent the trolley from becoming stuck on the rail 9 during movement. The guide rail 9 should be appropriately set based on the stacking position of the conveyor belt and the relative distance from the drum mixer to ensure that accumulated material is cleaned up.

[0031] When material accumulates beneath the batching conveyor head 12, the operator sends a command to the controller via the remote control terminal. Upon receiving the command, the controller activates the motor of the electro-hydraulic push rod 1, driving the trolley to reciprocate along the guide rails 9. During its movement, the pusher blade 5 within the trolley frame 3 scrapes up the accumulated material in the gap area and carries it into the drum mixer 13. By adjusting the motor frequency and push rod stroke, the trolley's movement speed and scraping efficiency can be flexibly controlled. Once the cleaning is complete, the operator sends another command via the remote control terminal to shut down the motor and stop the trolley.

[0032] The automatic material cleaning trolley provided by the utility model realizes the automatic cleaning function of the accumulated materials under the batching belt conveyor through reasonable design and layout, indirectly protects the use of the belt pressing cylinder and roller, relieves the labor intensity of workers on the job, and ensures the full recycling of the blanked materials. The trolley has a compact structure, is easy to operate, has high efficiency and low maintenance cost, and can significantly improve the automation level and production efficiency of the production line. Based on the original blanking speed of 10kg / 30min, 600kg of mineral materials can be cleared and reused per hour, and 14.4t of mineral materials can be cleared and reused per day. The price of each ton of material is 1,200-1,300 yuan, which can save 17,000-19,000 yuan per month. It will ensure that the cost of mineral materials of about 510,000 yuan will not be lost each month, and save about 10,000 yuan in labor costs.

[0033] The protection scope of the present invention is not limited to the above-mentioned specific embodiments, but covers all changes, modifications, combinations or applications based on the concept of the present invention without departing from the core spirit and substantial content of the present invention, which should be included in the protection scope of the present invention.
