[0029] Embodiment 1

[0030] The utility model provides a kind of self-cleaning scraper blade type dump truck, the self-cleaning scraper blade type dump truck includes carriage main body, the carriage main body includes side plate and bottom plate 3, the bottom plate 3 is provided with the scraper blade assembly around the bottom plate 3, the scraper blade assembly includes the chain 2 of left and right sides and the scraper blade 1 between two chains 2.The scraper blade 1 is around the bottom plate 3, the lower part of the bottom plate is also provided with brush, the chain 2 passes the brush.

[0031] The above-mentioned self-cleaning scraper blade type dump truck is provided with the scraper blade assembly around the bottom plate 3 on the bottom plate 3 of carriage, when needing to unload, the scraper blade assembly located at the upper part of bottom plate 3 drives material to move backward, the chain 2 of scraper blade assembly is easily adhered or extruded into material due to the hole, and the chain 2 adhered or extruded into material will affect the use of chain 2 when connecting with the driving structure such as chain wheel of chain 2.But in the embodiment, the chain 2 will pass the brush during rotation, and the soil and other materials adhered to the chain 2 can be cleaned by the brush, avoiding the influence of the material adhered to the chain 2 or extruded into the hole of chain 2 on the use of chain 2.

[0032] Specifically, in the embodiment, in order to avoid the scraper blade assembly located at the lower part of bottom plate 3 from falling, and to make the scraper blade assembly rotate stably around the bottom plate 3, the lower part of bottom plate 3 is also provided with two longitudinal support rods, and the scraper blade 1 is located at the upper part of the support rod.During the operation of the scraper blade assembly, the two support rods support the scraper blade 1, and also keep the chain 2 on both sides of the scraper blade 1 at a certain height, avoiding the falling or breaking of the scraper blade assembly.

[0033] Specifically, in the embodiment, in order to make each side of the brush clean the chain 2 uniformly, and avoid the problem that one side of the brush is overused while the other side cannot touch the chain 2, the brush is rotatably installed at the lower part of the bottom plate 3, that is, each side of the brush can clean the chain 2 uniformly during rotation.

[0034] Specifically, in the embodiment, the brush is a rolling brush, which includes a mounting shaft 5 located at the middle part and bristles 4 on the mounting shaft 5.The rolling brush can be driven to rotate by the movement of chain 2, or can be driven to rotate by other driving devices, when the driving device is needed, the mounting shaft 5 is connected with a driving device for driving the mounting shaft 5 to rotate, which can be a motor or other device, the brush is driven to rotate by the driving device, thereby improving the cleaning effect of the brush.

In addition, the sealing plate 6 is softer than the scraper 1 made of metal such as steel plate. When the hard material in the front part or the bottom plate 3 of the carriage collides with the scraper 1, the scraper 1 can also be prevented from jumping, so that the scraper 1 is attached to the bottom plate 3, the material remaining at the lower part of the scraper 1 is avoided, the scraper 1 is prevented from damaging other structures of the scraper assembly, and the service life of the scraper assembly is improved.

[0036] More specifically, in order to improve the protection effect of the sealing plate 6, the sealing plate 6 is generally made of rubber plate, and in order to make the scraper 1 better attach to the bottom plate 3 and buffer the collision between the scraper 1 and the bottom plate 3, the rear sealing plate 6 extends downward to the lower end of the rear end surface of the scraper 1 and extends downward by 0.1-3 cm. Through the arrangement, the lower end of the rear sealing plate 6 can abut against the bottom plate 3 of the carriage, so that the material is more completely scraped by the scraper 1, and the acting force between the scraper 1 and the bottom plate 3 of the carriage is buffered. Similarly, in order to better protect the upper part of the scraper 1 and make the sealing plate 6 bear the impact of the material, the rear sealing plate 6 extends upward to the upper end of the rear end surface of the scraper 1 and extends upward by 0.1-3 cm.

[0037] Specifically, in the embodiment, a plurality of scrapers 1 are arranged on the scraper assembly, but not all the scrapers 1 need to be provided with the sealing plate 6. In the embodiment, the sealing plates 6 are arranged on the scrapers 1 at intervals, that is, one sealing plate 6 is arranged in every two adjacent scrapers 1.

[0038] Specifically, in the embodiment, in order to facilitate installation of the sealing plate 6, corresponding mounting holes are arranged on the scraper 1 and the sealing plate 6, and the sealing plate 6 is installed on the scraper 1 by means of bolts penetrating through the mounting holes.

[0039] Of course, the above-mentioned is only the preferred embodiment of the present application, and does not limit the patent range of the present application. Any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection range of the present application, and should be protected by the present application.
