Description
Technical Field
[0001] This utility model belongs to the technical field of coal mining equipment, and more specifically, it relates to a portable cylindrical spiral bidirectional coal leveling device. Background Technology
[0002] The cylindrical spiral coal leveling device is a small tool used for coal leveling. It consists of a spiral roller, a manual drive device, and a support frame. Its working principle is to drive the spiral roller to rotate manually and use the spiral blades to push and scrape the coal in both directions. It is easy to operate and has low cost. It is suitable for small coal bunkers, freight cars, and temporary coal storage areas. However, the existing devices have a fixed spiral roller length, which makes it difficult to adapt to open scenarios with varying widths, resulting in adaptability defects and limited efficiency.
[0003] Portable cylindrical spiral coal leveling devices are key tools in small-scale coal mining operations. They achieve bidirectional pushing and leveling of coal by manually driving the spiral roller to rotate. Traditional structures use rigid fixed spiral rollers, which can meet basic leveling requirements in regular spaces such as standardized coal bunkers. However, they have adaptability defects in open scenarios with varying widths and complex boundaries, such as freight cars and temporary coal storage areas. This can easily lead to dead corners where coal accumulates, affecting operational efficiency and quality.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a portable cylindrical spiral bidirectional coal leveling device in order to achieve a more practical purpose. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Example:
[0024] As attached Figure 1 To be continued Figure 4 As shown:
[0025] This utility model provides a portable cylindrical spiral bidirectional coal leveling device, including two sets of main bodies 1 with opposite rotation directions. Both ends of the two sets of main bodies 1 are rotatably mounted with mounting frames 2. The two sets of mounting frames 2 are rotatably mounted with a smoothing base 3 through an angle adjustment mechanism. A drive mechanism 4 for driving the rotation of the two sets of main bodies 1 is provided on one side of the smoothing base 3. The drive mechanism 4 includes a first universal joint 401. Both ends of the first universal joint 401 are rotatably mounted with second joints 402. One end of each of the two sets of second joints 402 passes through the side wall of the two sets of mounting frames 2 and is fixedly connected to one end of the corresponding main body 1. A motor is installed on the side wall of one set of mounting frames 2, and the output end of the motor is connected to the corresponding end of the main body 1.
[0026] The angle adjustment mechanism includes two sets of first angle adjustment gears 7 and two sets of second angle adjustment gears 8. The two sets of first angle adjustment gears 7 and second angle adjustment gears 8 mesh with each other, and both sets of second angle adjustment gears 8 are rotatably mounted on the top side of the smoothing base 3 and are connected to a motor. The motors are fixedly connected to the side wall of the smoothing base 3. The bottom center of the two sets of first angle adjustment gears 7 is equipped with a pin. The bottom end of the two sets of pins is rotatably mounted on the top side of the smoothing base 3, and the top end is respectively installed through the side wall of the two sets of mounting frames 2. Through gear transmission, the tilt angle of the spiral body can be flexibly adjusted to adapt to different width operating scenarios such as freight cars and temporary coal storage areas, breaking through the limitations of traditional fixed structures and solving the problem of coal accumulation dead corners caused by complex boundaries in open scenarios.
[0027] Among them, the bottom side of the smoothing base 3 is equipped with a smoothing push plate for smoothing the blind area in the middle. The smoothing push plate has an L-shaped cross section. The L-shaped structure extends into the middle of the working surface, smoothing areas that are difficult to cover by traditional devices, reducing dead corners of coal accumulation, ensuring that the working surface is uniform and without omissions, and improving the efficiency and quality of coal smoothing.
[0028] Among them, a rotating shaft 9 is rotatably mounted on one side of the bottom of each of the two sets of mounting brackets 2, and two sets of sliding seats 10 are mounted on the bottom of the two sets of rotating shafts 9. The two sets of sliding seats 10 have an L-shaped cross section, and multiple sets of ball bearings are embedded on opposite sides of the two sets of sliding seats 10. Movement stability: The L-shaped structure enhances the support force, and the ball bearings reduce friction, making the device move more smoothly on complex ground. The rotating shaft 9 is designed to support multi-angle adjustment, improving operational flexibility.
[0029] Each of the two sets of sliding seats 10 has a movable wheel 11 installed on its bottom side, and the bottom of each set of sliding seats 10 is higher than the bottom of each set of movable wheels 11.
[0030] Among them, the top side of the smoothing base 3 is equipped with an operating frame 5, and the top two corners of the operating frame 5 are vertically equipped with movable handles 6.
[0031] Each of the two sets of mounting brackets 2 has a sliding groove 12 on its bottom side. Each set of mounting blocks 13 is slidably installed in the sliding groove 12. Each set of cleaning plates 14 is slidably installed at the bottom end of each set of mounting blocks 13. The two sets of cleaning plates 14 are located on both sides of the outer wall of the main body 1. Multiple sets of brushes are installed on the opposite side of each set of cleaning plates 14. When the main body 1 rotates, its outer wall contacts the brushes of the cleaning plates 14, generating friction. The friction causes the cleaning plates 14 to slide along the axial direction of the main body 1 instead of rotating, thereby pushing the mounting blocks 13 to move horizontally within the sliding groove 12. The cleaning plates 14 and the mounting blocks 13 are slidably installed and not fixedly connected, ensuring that the cleaning plates 14 only slide along the axial direction of the main body 1. The sliding groove 12 constrains the movement trajectory of the mounting blocks 13, so that the cleaning plates 14 cannot rotate with the main body 1 and can only slide in a straight line.
[0032] The working principle of this embodiment is as follows: The device includes two sets of main bodies 1 with opposite rotation directions. Driven by a motor, the spiral blades push coal in both directions during the rotation process, achieving efficient scraping and avoiding repetitive operations.
[0033] Angle adjustment mechanism: It consists of two sets of meshing first angle adjustment gears 7 and second angle adjustment gears 8. The motor controls the gears to rotate, which drives the mounting frame 2 to adjust the angle, so that the screw body can adapt to different width operating scenarios such as freight cars and temporary coal storage areas.
[0034] Universal drive design: The drive mechanism 4 adopts a first universal joint 401 and a second universal joint 402 to support multi-angle power transmission and enhance adaptability to complex boundaries.
[0035] L-shaped smoothing push plate: An L-shaped push plate is installed at the bottom of the smoothing base 3 to specifically smooth the central blind area and reduce dead corners for coal accumulation;
[0036] Automatic cleaning function: The cleaning plate 14 is slidably installed through the slide groove 12 and the mounting block 13, covering both sides of the outer wall of the main body 1. The brush cleans the residual coal in real time to ensure that the working surface is uniform and flat.
[0037] The movable wheel 11 and the sliding seat 10: The movable wheel 11 is installed at the bottom of the sliding seat 10, and the bottom of the sliding seat 10 is higher than the movable wheel 11 to reduce frictional resistance. The sliding seat 10 is inlaid with ball bearings to improve the stability of movement. By setting up two sets of sliding seats 10 on both sides of the edge of the coal storage car, the main body of the device can be moved.
[0038] Operation optimization: The operating frame 5 is equipped with a movable handle 6, which is easy to push manually and reduces operator fatigue.
[0039] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art.
