Referring to fig. 1 and 2, two ends of the trolley 1 in the length direction are respectively provided with a rotating shaft 3, two sides of the trolley 1 in the length direction are respectively connected with a supporting plate 31, and the rotating shafts 3 are rotatably connected with the supporting plates 31 on the two sides through bearings. Conveying chains 32 are respectively arranged on two sides of the long edge of the trolley 1, two ends of each conveying chain 32 are respectively meshed with a transmission chain wheel 33, and the transmission chain wheels 33 are respectively connected to the rotating shaft 3 in a rotating mode through bearings.

Referring to fig. 1 and 2, the conveying chains 32 are pallet chains, the conveying chains 32 on both sides are connected with mounting blocks 4 through bolts, a slag scraping plate 5 is connected between the mounting blocks 4, and the bottom side of the slag scraping plate 5 is attached to the upper surface of the trolley 1. In order to improve the stability of the conveying chain 32 during movement, two conveying chains 32 are provided on the same side of the trolley 1, and eight transmission chain wheels 33 are provided in cooperation with the conveying chains 32, wherein two transmission chain wheels 33 form a group.

Referring to fig. 1 and 2, when a workpiece is heat-treated, a portion of oxides generated from the workpiece may fall on the surface of the trolley 1. After the heat treatment of the workpiece is finished, the trolley is moved out of the hearth 2, the workpiece is conveyed away by using the lifting equipment, and partial oxide is left on the surface of the trolley 1. At this time, the worker rotates the transmission sprocket 33 on the rotation shaft 3 far from the hearth 2, and in order to improve the convenience of rotating the transmission sprocket 33, a first gear 34 is fixedly sleeved on the rotation shaft 3, a second gear 35 is meshed with the first gear 34, and the outer diameter of the second gear 35 is smaller than that of the first gear 34. The second gear 35 is connected to the carriage 1 through a bearing housing, and a handle 351 for driving the second gear 35 to rotate is provided on the bearing housing. Because the outer diameter of the second gear 35 is smaller than the outer diameter of the first gear 34, the worker can rotate the rotating shaft 3 with a smaller force than the direct rotation of the rotating shaft 3, and the labor-saving effect is achieved.

Referring to fig. 1 and 2, the rotating shaft 3 drives the transmission sprocket 33 to rotate during rotation, the transmission sprocket 33 drives the conveying chain 32 to move during rotation, so that the mounting block 4 drives the scraper 5 to move along the upper surface of the trolley 1, and the bottom side of the scraper 5 is attached to the upper surface of the trolley 1 during movement, so as to scrape off oxides on the upper surface of the trolley 1.

Referring to fig. 1, in order to reduce the amount of impurities overflowing through both ends of the slag scraping plate 5 during the slag scraping process, the slag scraping plate 5 is disposed in a "V" shape in a plan view. In the slag scraping process, the impurities are guided by the slag scraping plate 5 and are gathered towards the middle part of the slag scraping plate 5, so that the overflowing amount of the impurities through the two ends of the slag scraping plate 5 is reduced.
