Description

Technical Field

[0001] This utility model belongs to the technical field of carriage cleaning equipment, specifically a residual coal cleaning machine. Background Technology

[0002] During coal transportation, the interior of the wagons often requires regular cleaning due to the accumulation of coal dust and slag. This cleaning work not only affects transportation safety but also relates to environmental protection and operational efficiency.

[0003] Existing semi-automatic truck cleaning equipment typically involves using a crane to hoist the cleaning device, which then cleans the interior walls and bottom of the truck bed using tools such as roller brushes and scrapers. Currently, most cleaning equipment uses bolts or welding to fix the scrapers to the machine body, resulting in no adjustable scraper angle and no cushioning effect between the scraper and the machine body. This makes the scrapers prone to damage during the machine's forward or backward movement.

[0004] Therefore, this application proposes a coal scraper to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problems of existing snow removal equipment where the scraper is fixedly connected to the machine body, the scraper angle cannot be adjusted, and there is insufficient cushioning between the scraper and the machine body. A brief overview of this invention is provided below to offer a basic understanding of certain aspects of it. It should be understood that this overview is not an exhaustive summary of the invention. It is not intended to identify key or essential parts of the invention, nor is it intended to limit the scope of the invention.

[0006] The technical solution of this utility model:

[0007] The coal scraper includes a frame, a roller mechanism, a horizontal brush, a scraper mechanism, a motor, and a belt pulley transmission mechanism. The roller mechanism and the horizontal brush are rotatably mounted on the frame. The motor is fixedly mounted on the frame. The actuator of the motor is connected to the roller mechanism through the belt pulley transmission mechanism. Scraper mechanisms are symmetrically arranged on the left and right sides of the frame.

[0008] The scraper mechanism includes a mounting column, a first connecting rod, a second connecting rod, a scraper, and an elastic mechanism. The mounting column is connected to the frame, and the first connecting rod is mounted on the mounting column. The other end of the first connecting rod is hinged to one end of the second connecting rod, and the other end of the second connecting rod is hinged to the scraper. The mounting column and the scraper are connected through the elastic mechanism.

[0009] Furthermore, the elastic mechanism includes a connector, an adjusting ring, a spring, a support rod, and a base. A spring and a support rod are disposed between the connector and the base. The spring is fitted onto the support rod. One end of the spring is connected to the base, and the other end of the spring contacts the adjusting ring. An external thread is machined on the connector. The adjusting ring is threadedly connected to the connector. The connector is hinged to the mounting post, and the base is hinged to the scraper.

[0010] Furthermore, the roller mechanism includes a rotating shaft, a mounting plate, and blades. The two ends of the rotating shaft are rotatably mounted on the frame via bearing seats. Mounting plates are symmetrically arranged on the rotating shaft. Multiple blades are evenly distributed around the rotating shaft. The two ends of each blade are connected to the mounting plate.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0023] The connections mentioned in this utility model are divided into fixed connections and detachable connections. Fixed connections (i.e., non-detachable connections) include, but are not limited to, conventional fixed connection methods such as folded connections, riveted connections, adhesive connections, and welded connections. Detachable connections include, but are not limited to, conventional disassembly methods such as threaded connections, snap-fit ​​connections, pin connections, and hinged connections. When a specific connection method is not explicitly defined, it is assumed that at least one existing connection method can always be found to achieve the function, and those skilled in the art can choose according to their needs. For example, a welded connection can be chosen for fixed connections, and a hinged connection can be chosen for detachable connections.

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] Example 1, combined with Figures 1-5 This embodiment describes a residual coal sweeper, which includes a frame 1, a roller mechanism 3, a horizontal brush 4, a scraper mechanism 5, a motor 6, and a belt pulley transmission mechanism 7. The roller mechanism 3 and the horizontal brush 4 are rotatably mounted on the frame 1. The motor 6 is fixedly mounted on the frame 1. The actuator of the motor 6 is connected to the roller mechanism 3 through the belt pulley transmission mechanism 7. The scraper mechanism 5 is symmetrically arranged on the left and right sides of the frame 1.

[0026] The scraper mechanism 5 includes a mounting column 51, a first connecting rod 52, a second connecting rod 53, a scraper 54, and an elastic mechanism 56. The mounting column 51 is connected to the frame 1. The first connecting rod 52 is mounted on the mounting column 51. The other end of the first connecting rod 52 is hinged to one end of the second connecting rod 53. The other end of the second connecting rod 53 is hinged to the scraper 54. The mounting column 51 and the scraper 54 are connected through the elastic mechanism 56.

[0027] Before use, first adjust the position of the scraper 54. With the first connecting rod 52 and the second connecting rod 53 hinged at one end, and the second connecting rod 53 hinged to the scraper 54, adjust the angle and position of the scraper 54. In this embodiment, the positions of the scrapers 54 on both sides of the frame 1 are adjusted to a forward-opening type, as shown in the attached figure. Figure 1 As shown, during the overall movement of the frame 1, the scrapers 54 on both sides gather the material at the bottom of the carriage towards the center, and then clean it sequentially through the horizontal brush 4 and the roller mechanism 3. The scrapers 54 are unconventional scrapers; the front end of the scraper 54 is machined with an arc-shaped curved edge 58, and the inner side of the arc-shaped curved edge 58 has a handle 57. The function of the handle 57 is to facilitate the operator to adjust the scraper 54. The arc-shaped curved edge 58 ensures that the scraper 54 does not make hard contact with the side wall of the carriage during the movement of the frame 1, preventing the scraper 54 from being broken. The inner side of the scraper 54 is also machined with reinforcing ribs 55, which further improve the rigidity of the scraper 54.

[0028] The connector 59 of the elastic mechanism 56 connecting the scraper 54 and the mounting post 51 is hinged to the mounting post 51. The connector 59 has external threads. A support rod 62 is provided between the connector 59 and the base 63. The base 63 is hinged to the scraper 54. A spring 61 is fitted on the outside of the support rod 62. One end of the spring 61 is connected to the base 63, and the other end is disconnected from the adjusting ring 60. The adjusting ring 60 is connected to the connector 59 by a threaded connection. The tension of the spring 61 can be adjusted by turning the adjusting ring 60, thereby adjusting the buffer stroke of the scraper 54.

[0029] The roller mechanism 3 includes a rotating shaft 31, mounting plates 32, and blades 33. The two ends of the rotating shaft 31 are rotatably mounted on the frame 1 via bearing seats. Mounting plates 32 are symmetrically arranged on the rotating shaft 31. Multiple blades 33 are evenly distributed around the circumference of the rotating shaft 31, each blade 33 arranged with higher ends and a lower middle section. In use, a motor 6 mounted on the frame 1 serves as the drive source. When the motor 6 is turned on, its actuator drives the rotating shaft 31 to rotate via a belt drive mechanism 7. The belt drive mechanism 7 is a conventional belt drive mechanism, including a driving pulley, a driven pulley, and a belt. The driving pulley is connected to the actuator of the motor 6, and the driven pulley is connected to the rotating shaft 31. The driving pulley and the driven pulley are connected by a belt. When the rotating shaft 31 rotates, it drives the blades 33 mounted on its shaft to clean the bottom surface of the carriage. The blades 33, arranged with a lower middle section and higher ends, can effectively gather materials from the bottom of the carriage. A baffle 2 is also provided on the frame 1. The baffle 2 is arranged above the roller mechanism 3. The function of the baffle 2 is to prevent the blades 33 from lifting the material during the movement of the frame 1.

[0030] This embodiment is merely an exemplary illustration of this application and does not limit its scope of protection. Those skilled in the art can make partial changes to it, as long as they do not exceed the spirit and essence of this application, they are all within the scope of protection of this application.
