Problems solved by technology
When the second conveyor drives the second conveyor to rotate, if the angle of rotation is too large, there will be a large offset between the second conveyor's material receiving point and the first conveyor's blanking point, resulting in material leakage, increasing roadway cleaning work, and affecting roadheaders. Shipping efficiency
[0003] A secondary rotary structure in the related art has devices such as a guide shaft, a shift fork cylinder, a sliding frame, and a bead. The structures such as the guiding shaft and the sliding frame are not only complicated in structure, but also difficult in processing technology. At the same time, the actual When in use, the rotation effect is poor, and the offset cannot be completely offset, and there is still a relatively serious leakage of material

The invention provides a second conveyer revolving structure of a tunneling machine, comprising a connecting frame, a first connecting block, a second connecting block and a second conveyer revolving table, wherein the connecting frame is fixedly connected to the tunneling machine; one end of the first connecting block is rotationally connected with the connecting frame, and the other end of the first connecting block is rotationally connected with the second conveyer revolving table; one end of the second connecting block is fixedly connected with the connecting frame; the second conveyer revolving table is connected with the second connecting block through the matching of a slide block and a slide rail, when the tunneling machine is enabled to rotate, the connecting frame can drive the second conveyer revolving table to rotate through the first connecting block and the second connecting block. Correspondingly, the invention also provides a tunneling machine. By adopting the technical scheme provided by the invention, the alignment of the receiving point of a second conveyer to the receiving point of a first conveyer is realized, and further, the structure is simple and reliable, and the cost is low.
Description
technical field [0001] The invention relates to the technical field of mechanical rotary structures, and in particular, relates to a two-carriage rotary structure of a roadheader and a roadheader. Background technique [0002] At present, the rotary structure of the second transport (ie the second conveyor, referred to as "second transport") of the roadheader is basically connected to the tail of the second transport turntable through a long pin shaft, and the second transport rotary table and the connecting frame are directly connected through the pin shaft. Swivel connection. When the second conveyor drives the second conveyor's turntable to rotate, if the turning angle is too large, there will be a large offset between the second conveyor's material receiving point and the first conveyor's blanking point, resulting in material leakage, increasing the roadway cleaning work, and affecting the roadheader. Shipping efficiency. [0003] In the related art, a two-running rota...
