[0028] Embodiment 1

[0029] The embodiment provides a scraper assembly of a scraper truck, the scraper assembly of the scraper truck comprises a chain on both sides and a scraper 5 between the two chains, the chain comprises an inner chain plate 1 and an outer chain plate 2, that is, the chain in the scraper 5 assembly adopts the chain composed of the inner and outer chain plates 2 to drive, instead of the conventional ring chain. The inner chain plate 1 or the outer chain plate 2 is provided with a protruding plate 3, and the protruding plate 3 is provided with a mounting hole 4. The two ends of the scraper 5 are provided with U-shaped plates, the U-shaped plates are clamped on the protruding plate 3, the U-shaped plates are provided with connecting holes 8 corresponding to the mounting holes 4, and the scraper 5 assembly further comprises a mounting pin penetrating through the mounting holes 4 and the connecting holes 8.

[0030] The scraper assembly of the scraper truck, in which the protruding plate 3 is pre-set on the inner chain plate 1 or the outer chain plate 2, and the U-shaped plate is pre-set at both ends of the scraper 5, when the scraper 5 and the chain need to be connected, the protruding plate 3 is only inserted into the U-shaped plate, and then the protruding plate 3 and the U-shaped plate are connected through the mounting pin, thereby realizing the connection of the chain and the scraper 5. In this embodiment, the scraper 5 is connected by the chain composed of the inner and outer chain plates 2. The lower part of the chain of this type is consistent in height, that is, the lower end surfaces of the inner and outer chain plates 2 in the chain unit remain on a plane, which can reduce the vibration of the chain during movement, reduce the chain shock, and improve the stability of the operation of the scraper 5; at the same time, the chain plate structure of the chain is also convenient for setting the protruding plate 3, thereby facilitating the connection of the scraper 5 and the chain.

[0031] Specifically, in this embodiment, the running resistance of the scraper 5 is large, in order to improve the connection strength of the chain and the scraper 5, the protruding plate 3 extends along the longitudinal direction of the scraper 5 assembly, and only the protruding plate 3 is longitudinally arranged. At this time, when the scraper 5 is subjected to resistance of forward and backward movement, the protruding plate 3 can bear the resistance through a larger area, thereby improving the bearing capacity and avoiding the scraper 5 from being separated from the chain.

[0032] Specifically, in this embodiment, in order to facilitate installation and also to avoid interference between the protruding plate 3 and the chain plate of the chain, the protruding plate 3 is arranged on the outer chain plate 2. It should be noted that the scraper 5 is arranged at a predetermined distance, that is, not every outer chain plate 2 needs to be connected with the scraper 5.

[0033] Specifically, in this embodiment, a specific style of the U-shaped plate is also provided, the U-shaped plate includes an end plate 6 located at the end of the scraper 5, the upper side and the lower side of the end plate 6 are respectively provided with a transverse plate 7 extending towards the chain, and the end plate 6 and the transverse plate 7 form the U-shaped plate. Compared with directly forming a U-shaped structure by slotting on the scraper 5, the U-shaped plate formed by the end plate 6 and the transverse plate 7 can improve the strength of the U-shaped plate by increasing the strength of the end plate 6 and the transverse plate 7, which can be thickening, volume increase or material optimization, thereby avoiding the weak point of stress at the U-shaped plate.

[0034] Specifically, in this embodiment, in order to ensure the operation of the chain and avoid the chain from falling downward when running to the lower part of the bottom plate, the scraper 5 assembly further includes a support plate, the support plate is located at the lower part of the bottom plate of the truck compartment of the scraper 5, the support plate is welded and fixed on the longitudinal beam of the scraper 5 truck, and the chain is located at the upper part of the support plate.

[0035] Specifically, in the embodiment, in order to improve the service life of the scraper 5 and improve the scraping effect of the scraper 5, a rubber plate is arranged at the rear part of the scraper 5, and the rubber plate extends downward to the lower part of the lower end surface of the scraper 5. The rubber plate can make the scraper 5 scrape the material more completely, and the scraper 5 can also play a buffering role to avoid impact damage of the scraper 5.

[0036] 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 under the utility model concept of the present application is included in the patent protection range of the present application, and should be protected by the present application.
