For the spring 30, a second rotating shaft 19 is rotatably installed between the top pressure chambers 22 on the left and right sides. A drive motor 13 is installed at the right end of the second rotating shaft 19. The drive motor 13 is fixed in the right side wall of the top pressure chamber 22 on the right side, so that the eccentric wheel 23 can be driven to rotate by starting the drive motor 13. The rotation of the wheel 23 can drive the telescopic sliding block 20 and the pressing plate 29 to reciprocately press down, thereby pressing the waterproof membrane 50 to be flat.
 In addition, in one embodiment, the power unit includes a transmission cavity 38 disposed in the laying body 10 on the left side of the guide chute 47 , and the first rotating shaft 39 extends into the transmission cavity 38 and A worm gear 37 is fixed on the left end, a worm 36 is fixed on the front side of the worm gear 37, a third rotating shaft 11 is fixed on the top of the worm 36, and a power motor 17 is fixed on the top end of the third rotating shaft 11. The laying body 10 is also installed with a linkage unit that can control the lifting carriage 26 to slide up and down through the power of the power motor 17 , so that the third shaft 11 can be driven to rotate by starting the power motor 17 . The rotation of the third shaft 11 can drive the worm 36 to rotate, the worm 36 can drive the worm wheel 37, and the worm wheel 37 can drive the oval wheel 46 to rotate ninety degrees. 43 will approach each other, thereby holding the waterproof membrane 50.
 In addition, in one embodiment, the linkage unit includes a belt cavity 15 disposed in the laying body 10, the third rotating shaft 11 extends into the belt cavity 15 and a first pulley 12 is fixed thereon, so A screw 16 extending into the lift chute 27 is rotatably installed on the left side of the belt cavity 15, and a second pulley 18 is installed on the screw 16, and the first pulley 12 and the second pulley 18 are driven A transmission belt 14 is installed, and the screw 16 is threadedly connected with the lifting carriage 26, so that when the power motor 17 is started, the screw 16 can be driven to rotate, and the rotation of the screw 16 can control the lifting carriage 26 slides up and down, and then controls the rotating drum 32 to contact or separate from the waterproof membrane 50 .
 In addition, in one embodiment, a push rod 21 is installed on the upper left side of the laying body 10 , and rollers 51 are installed around the bottom end of the laying body 10 , so that the laying body 10 can be pushed to move to lay the waterproof membrane 50 . .
 In the initial state, the lift carriage 26 is on the top wall of the lift chute 27, and the clamping plates 42 on the front and rear sides are away from each other.
When the waterproof membrane 50 needs to be laid, a part of the waterproof membrane 50 is rolled up and the rolled up part is placed on the lower side of the rotating drum 32, and then, the cylindrical part of the waterproof membrane 50 is opposed to the cylindrical rods 43 on the front and rear sides Then, start the power motor 17, the power motor 17 drives the third shaft 11 to rotate, the rotation of the third shaft 11 drives the worm 36 to rotate, the worm 36 drives the worm wheel 37, and the worm wheel 37 drives the elliptical wheel 46 to rotate ninety degrees. The elastic pressing force of the second pressing spring 45 causes the cylindrical rods 43 on the front and rear sides to approach each other, thereby clamping the waterproof membrane 50. While clamping the waterproof membrane 50, the rotation of the third shaft 11 can drive the screw 16 Rotation, the rotation of the screw 16 can control the lifting carriage 26 to slide downward, and then control the rotating cylinder 32 to contact the waterproof membrane 50, and the rotating cylinder 32 can press the waterproof membrane 50 tightly through the action of the first pressing spring 34. Then, start the drive motor 13, the drive motor 13 drives the eccentric wheel 23 to rotate, and the rotation of the eccentric wheel 23 can drive the telescopic slide block 20 and the pressure plate 29 to reciprocate and press down, and at the same time, manually push the push rod 21 to make the laying body 10 move , and then the waterproof membrane 50 can be continuously laid and flattened.
 The beneficial effects of the present invention are as follows: the present invention has a simple structure and is easy to operate, and the waterproof membrane can be pressed by the rotating drum to keep the waterproof membrane in stable contact with the ground when the laying machine is pushed to move. The waterproof membrane is laid flat to prevent the phenomenon of hollowing, which can effectively reduce the use of manpower;
 Moreover, the present application can automatically clamp the waterproof membrane, the operation is simple and convenient, and a large number of disassembly and assembly processes are not required.
 Moreover, the present invention has an ingenious structure design. After the waterproof membrane is installed, the rotating drum can be automatically slid down to press down the part of the waterproof membrane that is rolled up, without manual repeated operation, and the automation efficiency is high.
 The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the present invention. within the scope of protection.
