Description

Technical Field

[0001] This utility model belongs to the field of waterproof membrane construction, and in particular relates to a waterproof membrane wet laying machine. Background Technology

[0002] The use of integrated wet-laying machines for waterproof membrane rolls is becoming increasingly common. These machines combine functions such as hopper operation, slurry spreading, waterproof membrane spreading, and membrane compaction, completing the process in one operation and significantly increasing efficiency compared to manual labor. However, most currently used integrated wet-laying machines for waterproof membrane rolls have the following drawbacks: 1. Poor sealing at the hopper discharge port, leading to leakage when not in use; 2. Inability to effectively spread and evenly distribute the slurry from the discharge port; 3. Lack of forward propulsion, requiring manual pushing by workers. Therefore, structural improvements to existing integrated wet-laying machines for waterproof membrane rolls are needed to overcome these problems. Summary of the Invention

[0003] The problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a waterproof membrane wet laying machine.

[0004] This invention is achieved through the following technical solution: A waterproof membrane wet-laying machine includes an integrated wet-laying machine. The frame of the integrated wet-laying machine is provided with a hopper, a membrane roll, and a pressure roll in sequence from front to back. The two ends of the pressure roll are hinged to the frame of the integrated wet-laying machine. A pallet valve is provided at the discharge port of the hopper. The two fan-shaped gates on both sides of the pallet valve are wrapped with U-shaped rubber pads at their closest ends. A support rod is fixed on the frame in front of the membrane roll. The support rod is located behind the hopper. A support plate is fixed downward on the lower surface of the support rod. A brush is fixed downward at the bottom of the support plate.

[0005] Preferably, a dual-axis motor is provided in the middle of the upper surface of the support rod. The left and right motor shafts of the dual-axis motor are respectively connected to the rotating shaft through bearings. The outer end of the rotating shaft is fixed together with the driving pulley. A driven pulley is fixed on the axle of the rear wheel of the wet paving machine. The driving pulley and the driven pulley are connected by a belt.

[0007] Preferably, the height of the brush is 4-6cm.

[0008] Preferably, the brush is fixed to the support plate by structural adhesive.

[0009] Preferably, the U-shaped rubber pad is a nitrile rubber pad.

[0010] This invention provides an integrated wet-laying machine for waterproof membranes. It ensures a tight seal at the material inlet to prevent grout leakage. After the grout is spread on the ground, a brush can spread and smooth the grout, ensuring the bonding quality of the waterproof membrane. At the same time, the machine can be moved forward by a dual-axis motor, reducing the labor intensity of workers.

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0014] This embodiment includes a wet-laying integrated machine, which is widely used on construction sites. The existing wet-laying integrated machine generally includes a hopper 1, a roll material roller 2, and a pressure roller 3 from front to back on the frame. The hopper 1 is used to hold the slurry and spread it through the discharge port. The roll material roller 2 is used to connect the waterproof membrane into a tube. The waterproof membrane can rotate around the roll material roller 2 and then be released and laid on the slurry. The pressure roller 3 is located at the rear of the wet-laying integrated machine. The two ends of the pressure roller 3 are hinged to the frame of the wet-laying integrated machine. The pressure roller 3 is placed on the ground and rolls the laid waterproof membrane to ensure a tight bond between the waterproof membrane and the slurry. The shut-off valve at the discharge port of hopper 1 is mostly a pallet valve 4. The pallet valve 4 includes two sector gates 5, two meshing gears 7, and two fixed shafts 6. The gears 7 can rotate around the fixed shafts 6. The two gears 7 are respectively connected to the sector gates 5 on both sides. By manually or through an actuator, pushing the rocker arm 18 causes the gears 7 to rotate the sector gates 5 along the axis, opening the two sector gates 5 to both sides, allowing the slurry to fall from the discharge port. When it is necessary to close the discharge port, pushing the rocker arm 18 again resets the sector gates 5, stopping the falling slurry, and the two sector gates 5 close the discharge port. In this embodiment, the pallet valve 4 used is a manual pallet valve. The front part of the rocker arm 18 of the pallet valve 4 is attached to the frame of the wet-laying machine, and the rear end of the rocker arm 18 is fixed to the sector gates 5. The pallet valve 4 is a common and mature component, and its structure and working principle will not be described in detail here. The existing jaw valve 4 has a shortcoming: when the two sector gates 5 are closed, they are difficult to close completely, leaving a gap between them, which causes slurry leakage. This embodiment improves upon this by wrapping U-shaped rubber gaskets 8 around the adjacent ends of the sector gates 5 on both sides of the jaw valve 4. This allows the gap between the two sector gates 5 to be completely filled by the U-shaped rubber gaskets 8 when they are closed, improving the sealing of the hopper 1's discharge port and solving the slurry leakage problem. In this embodiment, the U-shaped rubber gasket 8 is preferably made of nitrile rubber, which has good oil resistance, wear resistance, and sealing properties, and can better resist the erosion of the slurry inside the hopper 1.

[0015] The improvement in this embodiment lies in that a support rod 9 is fixed on the front frame of the roll material roller 2. The support rod 9 is parallel to the roll material roller 2 along the width direction of the wet-laying machine, and is located between the hopper 1 and the roll material roller 2. A vertical support plate 10 is fixed downward on the lower surface of the support rod 9, and a brush 11 is fixed downward at the bottom of the support plate 10. The brush 11 is used to spread and evenly distribute the falling slurry. In this embodiment, the brush 11 has a height of 4-6 cm and is bonded to the bottom of the support plate 10 with structural adhesive.

[0016] The improvement in this embodiment lies in that a dual-axis motor 12 is installed in the middle of the upper surface of the support rod 9. The left and right motor shafts of the dual-axis motor 12 are respectively connected to rotating shafts 13 via bearings. The rotating shafts 13 are supported on the frame of the wet paving machine via bearings. The outer ends of the rotating shafts 13 on both sides are fixed to the drive pulleys 14. Driven pulleys 16 are fixed on the axles of the two rear wheels 15 of the wet paving machine. The drive pulleys 14 and driven pulleys 16 are connected by a belt 17. The dual-axis motor 12 drives the rotating shafts 13 to rotate, the rotating shafts 13 drive the drive pulleys 14 to rotate, the drive pulleys 14 drive the driven pulleys 16 to rotate via the belt 17, and the driven pulleys 16 drive the axles to rotate, thereby driving the rear wheels 15 to rotate. The speed of the dual-axis motor 12 can be controlled by a controller, thereby controlling the travel speed of the entire wet paving machine, ensuring the paving and compaction quality, and also greatly reducing the labor intensity of workers.

[0017] During construction, slurry is placed into hopper 1, waterproof membrane is placed on roll roller 2, and the end of the waterproof membrane is placed on the ground. Dual-axis motor 12 is turned on, and rocker arm 18 is pushed to open the discharge port. Slurry leaks from the discharge port of hopper 1, and brush 11 spreads and smooths it evenly. The waterproof membrane rotates and is released to lay on the slurry. The pressure roller 3 at the rear compacts the laid waterproof membrane. Throughout the process, no worker needs to push the wet laying machine. The speed of the wet laying machine can be controlled according to the actual situation. After the construction is completed, dual-axis motor 12 is turned off, and rocker arm 18 is pushed to close the discharge port.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; those skilled in the art should understand that modifications can still be made to the technical solutions described in the above embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
