[0024] Refer to the instruction manual Figure 1-5 The utility model provides a hot rolling descaling machine, comprising a processing table 1 and a shell 2, wherein the shell 2 is fixed on the top of the processing table 1, a feed port 9 is provided at the front end of the shell 2, and a discharge port 10 is provided at the rear end of the shell 2, and a plurality of evenly distributed conveying rollers 3 are fixed on the top of the processing table 1, and the plurality of conveying rollers 3 are all arranged in the shell 2, and are used to convey the hot rolled plate to be descaled;

[0025] A plurality of rollers 7 are arranged inside the housing 2, and the plurality of rollers 7 are evenly distributed above the plurality of conveying rollers 3, and the bottoms of the plurality of rollers 7 are in contact with the top of the hot-rolled plate, and both ends of each roller 7 are fixed to the inner wall of the housing 2 through a bearing seat, and the rotation of the rollers 7 can reduce the friction between the rollers 7 and the hot-rolled plate;

[0026] The shell 2 is provided with a descaling component 4, which includes two frames 401, two water pipes 402 are fixedly provided inside the two frames 401, and multiple nozzles 403 are fixedly penetrated through the outer wall of the two water pipes 402 close to one side, and the multiple nozzles 403 are respectively connected to the inside of the two water pipes 402, and the two water pipes 402 are fixedly connected through a three-way pipe 404, and the two three-way pipes 404 are respectively fixed on the two frames 401;

[0027] In addition, the outer walls on both sides of the two frames 401 are connected with the same vertical plate 405, and the two sides of the top of the shell 2 are provided with a slide groove 8, and the two vertical plates 405 are respectively arranged in the two slide grooves 8. The tops of the two vertical plates 405 pass through the top of the shell 2, and the bottoms of the two frames 401 pass through the bottom of the shell 2. The slide groove 8 is used to limit the vertical plates 405, so as to improve the stability of the frame 401 when it is lifted or lowered. The two ends of the two three-way pipes 404 that are far away from each other are fixedly connected to the suction pump 6 connected to the water source. The two suction pumps 6 are respectively fixed on the two frames 401 and are used to deliver water to the water pipe 402.

[0028] Moreover, a lifting assembly 5 is provided on the outer wall of one side away from the two vertical plates 405, and the two lifting assemblies 5 both include electric push rods 501, and the two electric push rods 501 are fixed on the outer wall of the processing table 1, and the tops of the two electric push rods 501 are fixed with connecting plates 502, and the connecting plates 502 are fixed to the vertical plates 405;
