Abstract
Description
Technical Field
[0001] This utility model relates to the field of soil remediation, and in particular to a covering device for soil remediation. Background Technology
[0002] Soil remediation refers to the use of physical, chemical, and biological methods to transfer, absorb, degrade, and transform pollutants in the soil, reducing their concentration to acceptable levels, or converting toxic and harmful pollutants into harmless substances. Besides chemical remediation methods, physical methods such as mulching and water replenishment can also be used for remediation. A mulching device is used to cover the soil to be remediated, such as the soil covering device described in patent application number 202322470343.1, which uses a method of fixing one end of the mulch and using a winding wheel at the other end for covering and winding. However, it also has the following shortcomings:
[0003] First, its bottom frame cannot be moved in order to ensure stability after the coating is applied, and it needs to be lifted before and after use;
[0004] Secondly, the cylinder structure on it necessitates the installation of a cylinder drive structure, which increases the overall weight of the device and further increases the difficulty of lifting and carrying it during outdoor operations.
[0005] Moreover, the membrane layer is often moist due to water replenishment, and the soil adhering to it also has a certain degree of moisture, making it difficult for a single scraper to remove the adsorbed water and wet soil. Utility Model Content
[0006] The purpose of this invention is to provide a soil remediation covering device in order to solve the above-mentioned problems.
[0007] This utility model achieves the above objectives through the following technical solutions:
[0008] A soil remediation mulching device includes a base frame and a side-cushioning and lifting frame. The side-cushioning and lifting frame is fixedly installed on one end of the base frame. A winding frame is installed on the top side of the side of the side-cushioning and lifting frame. A mulching winding roller is rotatably installed on the winding frame via a winding shaft. The side-cushioning and lifting frame is provided with a pressing and adjusting groove. An adjusting slider is slidably installed in the pressing and adjusting groove. An upper pressing cylinder is rotatably installed on the adjusting slider via an upper pressing cylinder shaft. A lower pressing cylinder is rotatably installed on the side-cushioning and lifting frame below the upper pressing cylinder via a lower pressing cylinder shaft. A compression spring is connected and installed between the adjusting slider and the upper groove wall of the pressing and adjusting groove. A soil remediation membrane layer is pressed between the upper pressing cylinder and the lower pressing cylinder. A fixing clamping strip is installed at one end of the soil remediation membrane layer. The other end of the soil remediation membrane layer is wound onto the mulching winding roller.
[0009] Furthermore, the fixing clamping strip assembly consists of an upper pressure strip and a lower pressure strip. The upper pressure strip has insertion holes at both ends, and threaded ground nails are inserted into the insertion holes. The lower pressure strip has clamping threaded holes at both ends, and the threaded ground nails are threadedly connected to the clamping threaded holes.
[0010] Furthermore, a push cylinder is fixedly installed on one side of the base frame, a lifting column is inserted into the top of the push cylinder, and a push handle is installed on the top of the lifting column;
[0011] Furthermore, the lifting column is provided with several bolt holes, the push cylinder is provided with a cylinder thread hole, a cylinder bolt is internally threaded into the cylinder thread hole, and the end of the cylinder bolt is inserted into the bolt hole.
[0012] Furthermore, casters are installed at the bottom of the base frame.
[0013] Furthermore, a hexagonal slotted component is installed on one end of the take-up shaft.
[0014] The beneficial effects of this utility model are: the two ends of the film are more stable during the repair process, and the whole device is easy to move after winding. There is no need to drive the winding and lifting through the lifting structure. By squeezing and winding, the adsorbed water can be effectively removed and the wet soil can be reduced.

[0019] The present invention will be further described below with reference to the accompanying drawings:
[0020] like Figures 1-2 As shown, a soil remediation mulching device includes a base frame 1 and a side-cushioned lifting frame 2;
[0021] The side padding lifting frame 2 is fixedly installed on one end of the base frame 1. The top of the side of the side padding lifting frame 2 is equipped with a winding frame 3. The winding frame 3 is rotatably mounted with a film-coated winding roller 4 via a winding shaft.
[0022] The side pad lifting frame 2 is provided with a pressing adjustment groove 15. An adjustment slider 16 is slidably installed in the pressing adjustment groove 15. An upper pressure cylinder 21 is rotatably installed on the adjustment slider 16 through an upper pressure cylinder shaft 17. A lower pressure cylinder 19 is rotatably installed on the side pad lifting frame 2 below the upper pressure cylinder 21 through a lower pressure cylinder shaft. A compression spring 18 is connected between the adjustment slider 16 and the upper groove wall of the pressing adjustment groove 15, which drives the upper pressure cylinder 21 to press down and squeeze the water and wet soil.
[0023] A soil remediation membrane layer 5 is pressed between the upper pressure cylinder 21 and the lower pressure cylinder 19. One end of the soil remediation membrane layer 5 is equipped with a fixing clamping strip group, and the other end of the soil remediation membrane layer 5 is wound onto the film covering take-up roller 4.
[0024] like Figures 1-2 As shown, this utility model also discloses the following more optimized specific structures:
[0025] The fixing clamping strip assembly consists of an upper pressure strip 6 and a lower pressure strip 7. The upper pressure strip 6 has insertion holes at both ends, and threaded ground nails 7 are inserted into the insertion holes. The lower pressure strip 7 has clamping threaded holes at both ends, and the threaded ground nails 7 are threaded into the clamping threaded holes, so that they clamp the soil remediation membrane layer 5 and then fix it.
[0026] A push cylinder 10 is fixedly installed on one side of the base frame 1. The push cylinder 10 is away from the side pad lifting frame 2. A lifting column 13 is inserted into the top of the push cylinder 10. A push handle 14 is installed on the top of the lifting column 13.
[0027] The lifting column 13 is provided with several bolt holes 12, and the push cylinder 10 is provided with a cylinder thread hole. A cylinder bolt 11 is internally threaded into the cylinder thread hole, and the end of the cylinder bolt 11 is inserted into the bolt hole 12.

[0029] A hexagonal slotted rotating component 20 is installed on one end of the winding shaft, which is used to drive the shaft to rotate and rewind using a handheld rotating component.
[0030] like Figures 1-2 When using the soil remediation covering device shown, the fixing clip group is fixed to the end side of the soil remediation membrane 5, then stretched to cover the soil, and finally the side pad lifting frame 2 is flipped over to lay it on the ground and press the soil remediation membrane 5 to make it stable for a long time.
[0031] During winding, the side pad lifting frame 2 is flipped over so that the casters 9 support the ground. The hexagonal slotted rotating part 20 is connected to the hand-held rotating part (which can be an electric drive) to wind up the soil. During the winding process, the soil remediation membrane layer 5 is compressed to reduce moisture and wet soil.
