Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal transportation technology, specifically to a fully automatic hydraulic coal leveling device. Background Technology
[0002] Coal leveling is a crucial step in coal transportation. Traditional methods often rely on manual operation, which is not only inefficient but also difficult to guarantee the leveling effect. Some mechanized coal leveling devices have emerged on the market, but these devices are often complex in structure, cumbersome to operate, and lack precise control over the flatness of the coal.
[0003] According to a public announcement (publication number: CN221777088U), a fully automatic hydraulic coal leveler includes a gantry frame. A lifting mechanism is installed on the inner side of the gantry frame, and a lifting frame is mounted on the lifting mechanism. Two hangers are symmetrically slidably installed at the bottom of the lifting frame. Mounting plates are fixedly connected to the bottom of each hanger, and a rolling roller is installed between the two mounting plates. The rolling roller has multiple specifications. An adjustment mechanism for adjusting the distance between the two mounting plates is provided inside the lifting frame. This utility model allows for adjustment of the distance between the two mounting plates, enabling the fixing of rolling rollers of different specifications on the two mounting plates. This facilitates the replacement of the rolling rollers by workers according to the width of the car body and the type of coal. Selecting appropriate rolling rollers can improve the coal leveling efficiency and effect of the equipment.
[0004] While the aforementioned applications achieve coal leveling through lifting mechanisms and rolling rollers, their structures are relatively complex, resulting in high operation and maintenance costs. Furthermore, they require a large footprint, making operation inconvenient. Therefore, we propose a fully automatic hydraulic coal leveling device. Utility Model Content

A connecting column two is fixedly connected to the side of the lifting arm. Rollers are provided on the side of the lifting arm.
[0008] For example, in at least one embodiment of the present invention, a fully automatic hydraulic coal leveling device is provided, which further includes: a scraper, a scraper fixedly connected to the side of the lifting frame, a reinforcing rib fixedly connected to the bottom of the lifting frame, and the side of the reinforcing rib fixedly connected to the side of the scraper. Its function is to enhance the structural strength of the lifting frame. At the same time, the scraper can further level the coal on the worktable when the lifting frame moves, thereby improving the coal leveling effect.
[0009] The side of the lower pressure plate penetrates and slides through the circumferential surface of the limiting post, and the circumferential surface of the guide post penetrates and slides through the top of the lifting frame. Its function is to ensure the stability of the lower pressure plate during the lifting process and prevent it from shifting or shaking.
[0010] The guide pillars are provided in two symmetrical positions along the vertical central axis of the lifting frame. The side cross-section of the lower pressure plate is U-shaped, which increases the contact area between the lower pressure plate and the lifting frame and improves the stability of the lower pressure plate during the lifting process.
[0011] The first connecting column is located above the lower pressure plate, and the second connecting column is located below the lower pressure plate. Their function is to achieve effective connection and support of the lifting arm through the cooperation of the first connecting column and the second connecting column.
[0012] The rollers and lifting arms are arranged in a number that are symmetrical about each other along the vertical central axis of the lifting frame. The telescopic end of the hydraulic cylinder passes through and is slidably connected to the top of the lifting frame. The function of the rollers is to reduce the friction of the lifting arms during movement and improve the operating efficiency of the device.
[0013] The beneficial effects of the embodiments of this utility model are as follows: 1. This utility model achieves automatic, efficient, and stable leveling of coal through the cooperation of components such as the bridging plate, lifting frame, and hydraulic cylinder in the coal pressing device. During operation, the telescopic end of the hydraulic cylinder drives the lower pressing plate to move up and down. The lower pressing plate is guided by guide columns and limit columns, ensuring the stability of the lifting process. Simultaneously, the lifting arm and spring design provide a buffering effect when the lower pressing plate contacts the coal, preventing excessive compaction. The bottom scraper design further levels the coal during the lower pressing plate's lifting process, thereby improving the leveling effect. Attached Figure Description

[0022] like Figures 1-4 As shown, it illustrates a fully automatic hydraulic coal leveling device according to an embodiment of the present invention, including a workbench 1, a hydraulic system 2 on the top of the workbench 1, an electric lubrication pump 3 on the top of the workbench 1, an electrical control device 4 on the top of the workbench 1, a walking device 5 on the bottom of the workbench 1, a counterweight box 6 on the bottom of the workbench 1, and a coal pressing device 7 on the side of the workbench 1.
[0023] The coal pressing device 7 includes a bridging plate 701, which is fixedly connected to the side of the workbench 1. A lifting frame 702 is fixedly connected to the side of the bridging plate 701. A hydraulic cylinder 703 is fixedly connected to the top of the lifting frame 702. A lower pressure plate 704 is fixedly connected to the telescopic end of the hydraulic cylinder 703. A guide column 705 is fixedly connected to the top of the lower pressure plate 704. A limit column 706 is fixedly connected through the top of the lifting frame 702. A lifting arm 707 is hinged to the end of the limit column 706 away from the lifting frame 702. A spring 708 is provided on the circumferential surface of the limit column 706. A bottom scraper 709 is hinged to the bottom of the lower pressure plate 704. A connecting column one 710 and a connecting column two 711 are fixedly connected to the side of the lifting arm 707. A roller 712 is provided on the side of the lifting arm 707.
[0024] In some examples, a scraper 8 is fixedly connected to the side of the lifting frame 702, and a reinforcing rib 9 is fixedly connected to the bottom of the lifting frame 702. The side of the reinforcing rib 9 is fixedly connected to the side of the scraper 8. Its function is to enhance the structural strength of the lifting frame 702. At the same time, the scraper 8 can further scrape the coal on the workbench 1 when the lifting frame 702 moves, thereby improving the coal leveling effect.
[0025] The side of the lower pressure plate 704 is slidably connected to the circumferential surface of the limiting post 706, and the circumferential surface of the guide post 705 is slidably connected to the top of the lifting frame 702. Their function is to ensure the stability of the lower pressure plate 704 during the lifting process and prevent it from shifting or shaking.
[0026] There are two guide columns 705, which are symmetrical to each other along the vertical central axis of the lifting frame 702. The side section of the lower pressure plate 704 is set in a U-shape, which increases the contact area between the lower pressure plate 704 and the lifting frame 702 and improves the stability of the lower pressure plate 704 during the lifting process.
[0027] Connecting column 1 710 is located above the lower pressure plate 704, and connecting column 2 711 is located below the lower pressure plate 704. Their function is to achieve effective connection and support of the lifting arm 707 through the cooperation of connecting column 1 710 and connecting column 2 711.
[0028] The number of rollers 712 and lifting arms 707 is set to several, and they are symmetrical to each other along the vertical central axis of the lifting frame 702. The telescopic end of the hydraulic cylinder 703 passes through and slides through the top of the lifting frame 702. The function of the rollers 712 is to reduce the friction of the lifting arms 707 during the movement process and improve the operating efficiency of the device.
[0029] For example, such as Figures 1-4As shown, the operator activates the hydraulic system 2 via the electronic control device 4. The hydraulic system 2 drives the hydraulic cylinder 703 to extend and retract, and the extension end of the hydraulic cylinder 703 drives the lower pressure plate 704 to move up and down. During the raising and lowering of the lower pressure plate 704, the guide column 705 slides on the lifting frame 702 to ensure the stability of the lower pressure plate 704. At the same time, the concave design of the lower pressure plate 704 increases the contact area with the lifting frame 702, further improving stability. The lifting arm 707 is connected to the lower pressure plate 704 via connecting column one 710 and connecting column two 711, and moves with the raising and lowering of the lower pressure plate 704. The rollers 712 reduce the friction of the lifting arm 707 during movement, making the device operate more smoothly. When the pressure plate 704 descends, the bottom scraper 709 scrapes the coal to level it. At the same time, the scraper 8 further scrapes the coal as the lifting frame 702 moves, thereby improving the coal leveling effect. Meanwhile, the traveling device 5 drives the entire device to move, allowing the device to perform coal leveling operations in different working areas.
