Referring to fig. 1 to 3, the utility model provides a dumping mechanism of a dump truck, which comprises 2 chains respectively arranged at two sides of a carriage and scraping plates arranged on the chains and vertical to the length direction of the carriage,

wherein the chain comprises: a plurality of pairs of inner link plates 1 disposed opposite to each other and spaced apart from each other; the sleeves 2 are of a cylindrical structure and are inserted between two ends of the inner chain plate 1; the number of the pin shafts is the same as that of the sleeve 2, the pin shafts are inserted into the sleeve 2, and two ends of the pin shafts protrude outwards relative to two ends of the sleeve 2; a plurality of external link plates arranged opposite to each other and separately; two ends of the pin shaft sequentially penetrate through the inner chain plate 1 and the outer chain plate to enable the inner chain plate 1 and the outer chain plate to be connected, and the inner chain plate 1 and the outer chain plate are repeatedly arranged at intervals;

the outer chain plate is of a thin plate-shaped structure, the outer chain plate is axially symmetric in the width direction, two ends of one side of the outer chain plate in the width direction protrude outwards along the width direction of the outer chain plate and extend towards each other to form a pair of clamping lugs, the clamping lugs and the end surface of the outer chain plate surround to form a bayonet, and the clamping lugs are provided with screw holes.

The scraper blade is including the plate body that is square tubular structure, the plate body both ends are provided with the installation department, the plate body sets up in the bayonet socket, the installation department pass through the bolt with the screw is fixed, the installation department including set up in with plate body both ends and to the installation piece 11 that both sides extend, installation piece 11 is provided with the through-hole, the bolt can run through-hole and spiro union in 10, the installation department still including set up in the plate body both ends and to the inserted sheet 12 of the outside extension of scraper blade length direction, inserted sheet 12 can insert in bayonet 41.

With regard to the structure of the bayonet 41, specifically, the outer link plate 4 is axisymmetric in the width direction thereof, and is bilaterally symmetric in the drawing, both ends of one side of the outer link plate 4 in the width direction protrude outward in the width direction of the outer link plate 4 and extend oppositely to form a pair of clamping lugs 42, and the pair of clamping lugs 42 and the end surface of the outer link plate 4 surround to form the bayonet 41. In specific implementation, the minimum distance between the clamping lugs 42 is 35-40mm, the maximum width of the clamping opening 41 is 50-60mm, the height of the clamping opening 41 can be set to be 4-5mm, and in order to facilitate the placement of the scraper, the size of the scraper is used as a basis, and the scraper can be flexibly adjusted in specific implementation.

In the present embodiment, as shown in fig. 1, the end surface of the outer link plate 4 between the lugs 42 is disposed straight, which has an advantage in that the scraper is structurally stable after installation and is not easily deformed. The end faces of the inner chain plate 1 on the same side as the clamping lugs 42 are arranged straightly, and the upper end face of the inner chain plate 1 does not protrude out of the outer chain plate 4 in the rotating process in order not to influence the rotating action.
