[0002] The high-density polyethylene film, abbreviated as HDPE film, is a plastic coil composed of HDPE. HDPE is a thermoplastic resin with high crystallinity and non-polarity. The main advantages of using HDPE film are its excellent anti-seepage performance, corrosion resistance and durability. It can effectively extend the service life of landfills, reduce the risk of environmental pollution, and ensure the safety of the surrounding ecological environment. When the current device is working, due to the limited length of the high-density polyethylene film, it needs to be replaced after use. However, it is not convenient to replace the high-density polyethylene film.

[0003] In the prior art CN213836758U, through the designed second connecting block, rotating shaft, connecting shaft and limiting block, it is convenient to rotate the connecting shaft upward, so that the film body can be drawn out from the upper part for replacement. Through the provided first connecting block, inserting rod, pull ring, fixing plate and first spring, it is convenient to fix the connecting shaft, so that the film body can rotate smoothly on the connecting shaft, solving the problem of inconvenient replacement of the high-density polyethylene film.

[0004] After the HDPE film is laid by this device, it cannot effectively compact the HDPE film. The HDPE film may not fit closely with the ground, resulting in a shortened service life of the laid HDPE film. Content of the Utility Model

[0005] The purpose of the utility model is to provide an HDPE film laying device for the bottom of a landfill, which solves the problem that after the HDPE film is laid by this device, it cannot effectively compact the HDPE film, and the HDPE film may not fit closely with the ground, resulting in a shortened service life of the laid HDPE film.

Detailed Embodiment

[0018] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0019] The first embodiment of this application is as follows:

[0020] Please refer to Figure 1 - Figure 2 , Figure 1 , which is a schematic diagram of the overall structure of the first embodiment of the HDPE film laying device at the bottom of the landfill of the present utility model. Figure 2 , which is a schematic diagram of the overall structure of the first embodiment of the HDPE film laying device at the bottom of the landfill of the present utility model in another direction.

[0021] The present utility model provides an HDPE film laying device at the bottom of a landfill, including a base 101, four walking wheels 102 and a compaction mechanism. The compaction mechanism includes two electric telescopic rods 103, a fixing plate 104, a telescopic assembly, a mounting rod 106, a mounting frame 112, a limiting assembly, two reinforcing rods 105, a rotating shaft 113 and a pressure roller 114. The base 101 has a through groove 111. The telescopic assembly includes a telescopic spring 107 and a mounting plate 108. The limiting assembly includes a fixing frame 109 and a sleeve 110. Through the foregoing solution, the problem that the HDPE film cannot be effectively compacted after being laid by the device, and the HDPE film may not fit tightly with the ground, resulting in a shortened service life of the laid HDPE film, is solved.

[0022] In this specific embodiment, the four walking wheels 102 are arranged above the base 101. The two electric telescopic rods 103 are fixedly connected to the base 101 and are located on both sides of the through groove 111. The two ends of the fixing plate 104 are respectively fixedly connected to the output ends of the two electric telescopic rods 103. The telescopic assembly is arranged on the fixing plate 104. One end of the mounting rod 106 is arranged on one side of the telescopic assembly. The other end of the mounting rod 106 passes through the through groove 111 and is fixedly connected to the mounting frame 112. The rotating shaft 113 is rotatably connected to the mounting frame 112 and is located inside the mounting frame 112. The pressure roller 114 is rotatably connected to the rotating shaft 113. When laying the HDPE film, the two electric telescopic rods 103 are started simultaneously. The piston rods of the two electric telescopic rods 103 contract and drive the fixing plate 104 to move downward. The downward movement of the fixing plate 104 brings a downward pressure to the mounting rod 106 through the telescopic assembly. The mounting rod 106 transmits the downward pressure to the pressure roller 114 through the mounting frame 112. The pressure roller 114 presses on the HDPE film. When laying the HDPE film, the four walking wheels 102 drive the device to move. At this time, the pressure roller 114 rotates around the rotating shaft 113 as the central axis. The pressure roller 114 rolls on the ground where the HDPE film has just been laid, pressing the HDPE film firmly on the ground, thereby increasing the service life of the HDPE film.

[0023] Wherein, two ends of the telescopic spring 107 are fixedly connected to the fixed plate 104 and the mounting plate 108 respectively. One end of the mounting rod 106 is fixedly connected to the mounting plate 108 and is located inside the telescopic spring 107. The fixing frame 109 is fixedly connected to the base 101 and is located above the through groove 111. The sleeve 110 is fixedly connected to the fixing frame 109. The mounting rod 106 is slidably connected to the sleeve 110 and is located inside the sleeve 110. The two reinforcing rods 105 are respectively fixedly connected to two ends of the fixed plate 104. When laying the HDPE film, the two electric telescopic rods 103 are started simultaneously. The piston rods of the two electric telescopic rods 103 contract and drive the fixed plate 104 to move downward. At this time, the telescopic spring 107 is always in a stretched state. The fixed plate 104 gives a downward pulling force to the telescopic spring 107, and the telescopic spring 107 pulls the mounting plate 108 downward. The mounting plate 108 transmits the downward pressure to the pressure roller 114 through the mounting rod 106, the mounting frame 112 and the rotating shaft 113, so that the pressure roller 114 obtains a downward pressure greater than its own gravity. The pressure roller 114 presses on the HDPE film. When laying the HDPE film, the four traveling wheels 102 drive the device to move. At this time, the pressure roller 114 rotates around the rotating shaft 113 as the central axis. The pressure roller 114 rolls on the ground where the HDPE film has just been laid, pressing the HDPE film firmly on the ground, thereby increasing the service life of the HDPE film. The fixing frame 109 and the sleeve 110 limit the mounting rod 106, and the mounting rod 106 can only slide up and down inside the sleeve 110 to ensure that the mounting rod 106 remains vertical during use, and further ensure the downward pressure of the pressure roller 114. When the device works, the fixed plate 104 will bear the upward pulling force of the telescopic spring 107 and the downward pulling force of the two electric telescopic rods 103. The two reinforcing rods 105 reinforce the fixed plate 104 to ensure that the fixed plate 104 will not deform when the device works, increasing the structural stability of the device.

[0024] When laying the HDPE film using the present utility model, two of the electric telescopic rods 103 are started simultaneously. The piston rods of the two electric telescopic rods 103 contract, driving the fixed plate 104 to move downward. At this time, the telescopic spring 107 remains in a stretched state all the time. The fixed plate 104 gives a downward pulling force to the telescopic spring 107, and the telescopic spring 107 pulls the mounting plate 108 downward. The mounting plate 108 transmits the downward pressure to the pressure roller 114 through the mounting rod 106, the mounting bracket 112, and the rotating shaft 113, so that the pressure roller 114 obtains a downward pressure greater than its own gravity. The pressure roller 114 presses on the HDPE film. When laying the HDPE film, the four traveling wheels 102 drive the device to move. At this time, the pressure roller 114 rotates around the rotating shaft 113 as the central axis. The pressure roller 114 rolls on the ground where the HDPE film has just been laid, pressing the HDPE film firmly on the ground, thereby increasing the service life of the HDPE film. The fixed frame 109 and the sleeve 110 limit the mounting rod 106. The mounting rod 106 can only slide up and down within the sleeve 110, ensuring that the mounting rod 106 remains vertical during use, and further ensuring the downward pressure of the pressure roller 114. When the device works, the fixed plate 104 will bear the upward pulling force of the telescopic spring 107 and the downward pulling force of the two electric telescopic rods 103. The two reinforcing rods 105 reinforce the fixed plate 104, ensuring that the fixed plate 104 will not deform when the device works, and increasing the structural stability of the device.

[0025] The second embodiment of the present application is as follows:

[0026] Please refer to Figure 3 , Figure 3 which is the overall structural schematic diagram of the second embodiment of the HDPE film laying device for the bottom of the landfill of the present utility model. On the basis of the first embodiment, the HDPE film laying device for the bottom of the landfill of this embodiment further includes a dust cleaning mechanism. The dust cleaning mechanism is arranged on the base 101. The dust cleaning mechanism includes an air pump 201, an air guide pipe 202, and an air outlet pipe 203.

[0027] The air pump 201 is fixedly connected to the base 101. The two ends of the air guide pipe 202 are respectively fixedly connected to the output end of the air pump 201 and the air outlet pipe 203 and are in communication. When laying the HDPE film, the air pump 201 is started. The air pump 201 generates high-pressure air flow. The high-pressure air flow is discharged from the air outlet pipe 203 through the air guide pipe 202, blowing away the dust particles on the ground, so that the laid HDPE film fits the ground better, and further increasing the durability of the HDPE film.

[0028] The above-disclosed are only one or more preferred embodiments of the present application, and cannot be used to limit the scope of rights of the present application. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
