[0057] The conveying assembly is provided in two groups, and the two groups of conveying assemblies are symmetrically arranged above the frame 2. The conveying assembly comprises an L-shaped frame 601 fixed on the mounting plate 401, two rotating shafts 602 rotationally connected to the L-shaped frame 601, two conveying rollers 603 fixed on the two rotating shafts 602, the protective net 1 passing through and abutting between the two conveying rollers 603, and a third motor 604 mounted on the L-shaped frame 601 for driving the rotating shafts 602. The third motor 604 is driven, the conveying rollers 603 on the rotating shafts 602 are driven to rotate by the third motor 604, because the conveying rollers 603 abut against the protective net 1, the protective net 1 is conveyed by pulling through the rotation of the conveying rollers 603, and the conveyed protective net 1 is laid from the upper side to the lower side of the slope.

[0058] Working principle: in the process of laying the protective net 1, the protective net 1 to be laid is wound on the winding wheel 3, after winding is completed, the winding wheel 3 is moved to the upper side of the frame 2 and between the two mounting plates 401, after the movement is completed, the second motor 504 is started, the double-end screw rod 502 is driven to rotate by the second motor 504, in the process of rotation of the double-end screw rod 502, the two threaded sleeves 503 are respectively meshed with the two ends of the double-end screw rod 502 for transmission, the two mounting plates 401 are driven to move under stress, in the process of movement of the two mounting plates 401, the two mounting plates 401 after stress are driven to move close to each other under the guiding action of the guide rods 505, in the process of movement of the two mounting plates 401 close to each other, the two splines 402 are respectively inserted into the spline sleeves 403 on the two sides of the winding wheel 3, the winding wheel 3 is installed between the two mounting plates 401 through the connecting action of the two splines 402 and the two spline sleeves 403;

[0060] In the process of laying and conveying the protective net 1, the moving assembly and the guiding assembly drive the strip-shaped plate 7 to move towards the winding wheel 3. In the process of movement, the first connecting assembly drives the two U-shaped frames 1002 to move synchronously. In the process of movement of the strip-shaped plate 7 and the two U-shaped frames 1002, the flattened rollers 1004 on the two U-shaped frames 1002 abut against the protective net 1 on the winding wheel 3. Through the abutting limiting action of the two flattened rollers 1004 on the protective net 1 and the continuous moving action of the moving assembly and the guiding assembly on the strip-shaped plate 7, the strip-shaped plate 7 moves towards the two abutted and limited U-shaped frames 1002. In the process of movement, through the abutting transmission action of the two inclined grooves 1202 on the transmission plate 1201 and the two transmission pins 1203, the two U-shaped frames 1002 are driven to move under stress. In the process of movement of the two U-shaped frames 1002 under stress, the first connecting assembly drives the two U-shaped frames 1002 under stress to move away from each other. Since the flattened rollers 1004 on the two U-shaped frames 1002 abut against the protective net 1, in the process of movement of the two U-shaped frames 1002 away from each other, the two flattened rollers 1004 extrude and flatten the protective net 1, thereby ensuring the quality of the conveying and laying of the protective net 1. In the process of movement of the two U-shaped frames 1002 and the sliding plate 1001 away from each other under stress, with the sliding of the sliding plate 1001, the inclined surface 1303 of the limiting plate 1301 on the sliding plate 1001 abuts against the limiting rod 1305 on the L-shaped plate 1304. Through the abutting limiting action of the inclined surface 1303 and the limiting rod 1305 and the sliding guiding action of the second connecting assembly on the L-shaped plate 1304 under stress, the L-shaped plate 1304 is driven to slide on the strip-shaped plate 7, so that the limiting rod 1305 does not abut against the inclined surface 1303 but slides out of the limiting hole 1302 in front of the limiting rod 1305 with the continuous sliding of the sliding plate 1001. Through the resetting pushing action of the second connecting assembly on the L-shaped plate 1304, one end of the limiting rod 1305 is clamped into the inside of the limiting hole 1302. Through the limiting action of the limiting rod 1305 and the limiting hole 1302 on the sliding plate 1001 and the U-shaped frame 1002 after movement, the effect of the flattened rollers 1004 on the upper end of the U-shaped frame 1002 on the flattened protective net 1 is avoided. After flattening, the moving assembly and the guiding assembly drive the strip-shaped plate 7 to reset. In the process of resetting, the push plate 15 abuts against the connecting plate 1306, the L-shaped plate 1304 is pushed to slide, in the process of sliding, the limiting rod 1305 is driven to slide out of the limiting hole 1302. At this time, the sliding plate 1001 is no longer limited and is reset. Through the flattened operation of the sliding plate 1001, the protective net 1 is flattened repeatedly

[0061] The application forms automatic net laying operation in the process of slope protection construction, and manual net laying is no longer needed, thereby reducing labor intensity and safety hazards of operators in the process of net laying construction. Through transmission, two U-shaped frames under stress are driven to move away from each other. The flattened rollers on the two U-shaped frames abut against each other. In the process of moving away from each other, the flattened rollers extrude and flatten the protection net, thereby ensuring the quality of the conveying and laying of the protection net.
