[0015] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model more clear, the utility model technical scheme will be described clearly and completely in combination with the embodiment and the drawings of the specification.

[0016] EMBODIMENT

[0017] Figs. 1-3 In the embodiment, the double-spiral stirring feeding integrated machine suitable for mine roadway wet spraying construction comprises a connecting assembly, the connecting assembly is used for connecting the outlet of the feeding integrated machine and external equipment, the connecting assembly comprises a front connecting piece 10, a rear connecting piece 20 and a hose 30, the two ends of the hose 30 are fixedly connected with the front connecting piece 10 and the rear connecting piece 20 respectively, and a plurality of support pieces 40 are arranged between the front connecting piece 10 and the rear connecting piece 20.

[0018] The middle part of the hose 30 is arranged in a folded shape, and a corrosion-resistant layer is arranged on the inner surface of the hose 30.

[0019] In the drawings and the abstract, the front connecting piece 10, the rear connecting piece 20 and the hose 30 are only examples, the shape of the front connecting piece 10, the rear connecting piece 20 and the hose 30 is not limited, and the cross section of the hose 30 can be circular or polygonal.

[0020] The set hose 30 is connected with the outlet of the feeding integrated machine and external equipment, the feeding direction can be adjusted at will by the flexibility of the hose 30, the equipment position is adjusted or the discharge requirement in different directions is adapted.

[0021] Figs. 1-3 In the embodiment, the support 40 comprises a screw rod 41, both ends of which are movably sleeved with rotating balls 42, and the two rotating balls 42 are respectively rotatably inserted into the front connecting plate 10 and the rear connecting plate 20.

[0022] The screw rod 41 is threadedly sleeved with limiting blocks 43 on both sides of the rotating balls 42, and the limiting blocks 43 are surface-adhered to the rotating balls 42.

[0023] The support 40 can support the front connecting plate 10 and the rear connecting plate 20 at any length, and the hose 30 can be bent at different directions and angles by different support distances of the supports 40, without the need of replacing the adapter, and the use is more convenient.

[0024] Working principle: when the outlet of the feeding integrated machine is connected with external equipment, the bending state of the connecting assembly needs to be adjusted so that it can be used in cooperation with the outlet of the feeding integrated machine and the external equipment, the limiting blocks 43 are first rotated to be away from the surface-adhered position of the rotating balls 42 by a certain distance, after the limiting blocks 43 on both sides are adjusted, the front connecting plate 10 or the rear connecting plate 20 is pushed on one side to drive the hose 30 to bend, because the middle part of the hose 30 is arranged in a folded shape, the hose 30 can be bent at any angle, and the multiple rotating balls 42 are deflected by a corresponding angle to automatically adjust, then the limiting blocks 43 are rotated back to be surface-adhered to the rotating balls 42, the distance between the two rotating balls 42 is limited and fixed, the multiple supports 40 connect the front connecting plate 10 and the rear connecting plate 20 at different distances, so that the support of the hose 30 is completed, then the front connecting plate 10 and the rear connecting plate 20 are fixedly installed with the outlet of the feeding integrated machine or the external equipment by using bolts and other fixing members, and the already installed connecting assembly can also be adjusted in the bending state by using the same method.

[0025] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them.
