[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 5 .

[0028] In view of the problems mentioned in the above background technology, the embodiment of the utility model provides a double-layer conveying device to solve the above technical problems, and its technical solution is as follows:

[0029] A double-layer conveying device, comprising:

[0030] A first conveying device 200, a second conveying device 300 and a plurality of height adjustment devices 400; the second conveying device 300 is arranged on the first conveying device 200 through the plurality of height adjustment devices 400;

[0031] The second conveying device 300 includes two second side plates 310, a plurality of rollers rotatably arranged between the two second side plates 310, and a conveying belt drivingly connected to the plurality of rollers;

[0032] The second side plate 310 includes an upper top plate 311 and a lower bottom plate 312 which are arranged parallel to each other and spaced apart from each other, and a vertical connecting plate connecting the upper top plate 311 and the lower bottom plate 312;

[0033] The height adjustment device 400 includes a fixing seat 410, a long head bolt 420, an upper nut 431, and a lower nut 432;

[0034] The fixing seat 410 is fixed on the first side plates 210 on both sides of the first conveying device 200;

[0035] The long head bolt 420 is vertically fixed on the fixing seat 410;

[0036] The lower bottom plate 312 on the second side plate 310 is provided with a plurality of mounting holes 312a that match the positions of the long head bolts 420;

[0037] The long head bolt 420 is vertically inserted into the mounting hole 312a, and the upper nut 431 and the lower nut 432 are connected to the long head bolt 420 up and down and are respectively located at the top and bottom of the lower base plate 312; tightening the upper nut 431 and the lower nut 432 can lock the second side plate 310 on the long head bolt 420.

[0038] The working principle of a double-layer conveying device provided by an embodiment of the utility model is as follows: when height adjustment is required, the second conveying device 300 is dragged by lifting or hoisting equipment; the worker adjusts the height position of the upper nut 431 and the lower nut 432 on the long head bolt 420 until it is adjusted to a suitable position, then lifts or drops the second conveying device 300 to a suitable position, and then tightens the upper nuts 431 and the lower nuts 432 on both sides of the lower base plate 312.
