The lifting device includes a screw, the first end of which is fixedly connected to support B, the second end of which passes through support A, and an adjusting rod connected to the second end of the screw via a threaded drive, the adjusting rod being located above support A. This device can improve the processing quality and efficiency of sluice box roasting.

[0004] The sluice box roasting apparatus similar to the one mentioned above still has the following shortcomings:

[0006] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed an improved chute roasting device with a gas leak prevention structure, in order to achieve a more practical purpose. Utility Model Content
