[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figure 1-7, the present invention provides a technical solution: a sand quality improvement device for coastal beach restoration, including a sand quality improvement device main body 1. An installation plate 6 is provided on the sand quality improvement device main body 1, and support rollers 5 are symmetrically installed on both sides of the lower end of the installation plate 6. Above the installation plate 6 is a screening drum 11, and a screen 1103 is provided on the screening drum 11. And a feed hole 1104 is opened at the front end of the screening drum 11. A material guiding hopper 7 and a waste collection box 9 are penetrated and clamped on the installation plate 6. And the material guiding hopper 7 is located below the screen 1103, and the waste collection box 9 is located below the tail end of the screening drum 11. A positioning cylinder 2 is provided at the front end of the screening drum 11. An upper cover plate 204 is fixed to the upper end of the positioning cylinder 2 by bolts, and a second lifting hydraulic cylinder 10 is fixed to the upper end of the upper cover plate 204 by bolts. This structure enables the positioning cylinder 2 to play a role in actively limiting the installation cylinder 13. Through the active penetration and cooperation between the positioning cylinder 2 and the discharge branch pipe 1301, the lifting adjustment of the installation cylinder 13 is not affected. And an installation cylinder 13 is movably inserted into the positioning cylinder 2. The output end of the second lifting hydraulic cylinder 10 is penetrated and cooperated with the upper cover plate 204, and the output end of the second lifting hydraulic cylinder 10 is bolted to the top of the shell of the installation cylinder 13. This structure enables the installation cylinder 13 to perform lifting adjustment processing relative to the positioning cylinder 2 under the positioning of the upper cover plate 204. A first positioning sleeve 201 and a second positioning sleeve 202 with corresponding structures are sleeved outside the positioning cylinder 2, and the bottom of the positioning cylinder 2 is a flared support skirt 203. This structure enables the positioning cylinder 2 to be reliably supported at the bottom by the support skirt 203 during positioning. And through the setting of the support skirt 203, the spiral feeder 4 can be protected, making the sand quality improvement construction safer. The first positioning sleeve 201 is movably matched with the positioning cylinder 2, and the first positioning sleeve 201 is bolted to the installation plate 6. This structure enables the positioning cylinder 2 to move relative to the installation plate 6 under the limitation of the first positioning sleeve 201. The second positioning sleeve 202 is bolted to the positioning cylinder 2, and a first lifting hydraulic cylinder 3 is bolted between the second positioning sleeve 202 and the installation plate 6. This structure enables the second positioning sleeve 202 to perform lifting processing through the first lifting hydraulic cylinder 3, and the lifting movement of the positioning cylinder 2 relative to the installation plate 6 can be realized. Therefore, when the positioning cylinder 2 descends, it can be reliably supported by the support skirt 203. And after the positioning cylinder 2 rises, it does not affect the movement of the support rollers 5. And a spiral feeder 4 is rotatably installed in the installation cylinder 13. An inclined discharge branch pipe 1301 is integrally provided on the side of the installation cylinder 13, and the discharge branch pipe 1301 is movably penetrated and cooperated with the installation cylinder 13. And the discharge branch pipe 1301 is located in the feed hole 1104. An electric motor support frame 8 is fixed to the upper end of the installation plate 6 by welding, and a rotating electric motor 12 is bolted above the electric motor support frame 8. The output end of the rotating electric motor 12 is connected to the middle part of the tail end of the screening drum 11 through a coupling. This structure drives the screening drum 11 to rotate through the rotating electric motor 12, enabling the sand entering the screening drum 11 to be screened to remove impurities in the sand.The main body 1 of the sandy soil improvement device directly takes materials on the coastal sandy land through the screw feeder 4, reducing transportation equipment. At the same time, by adjusting the lifting of the installation cylinder 13, the depth of material taking can be controlled to better carry out the sandy soil improvement treatment. A positioning collar 1101 is fixed to the outer ring of the front end of the screening drum 11 by bolts, and a groove is provided in the middle of the outer ring of the positioning collar 1101. With this structure, the screening drum 11 can be stably processed at the front end through the positioning collar 1101. Auxiliary support rollers 1102 that are respectively engaged with the groove parts of the positioning collar 1101 are provided on both sides of the front end of the screening drum 11, and the fixed ends of the auxiliary support rollers 1102 are fastened to the mounting plate 6. With this structure, through the engagement of the auxiliary support rollers 1102 with the positioning collar 1101, the function of anti-deviation positioning is achieved, avoiding the influence on the rotation of the screening drum 11. A material guiding slope 902 is provided at the bottom of the waste collection box 9, and a through hole is provided at the lowest end of the material guiding slope 902 of the waste collection box 9. And an outlet control plate 901 is fixed to the through hole of the waste collection box 9 by bolts. With this structure, the waste collection box 9 can collect and process the screened impurities, and facilitate the discharge of the impurities. And during the movement of the main body 1 of the sandy soil improvement device, the screened sand can be leveled through the material guiding slope 902, improving the efficiency of coastal beach restoration.,

[0026] Working principle: When using the sand quality improvement device for coastal beach restoration, first, the main body 1 of the sand quality improvement device moves on the beach through the frame structure composed of the mounting plate 6 and the support rollers 5. First, start the first lifting hydraulic cylinder 3, so that the first lifting hydraulic cylinder 3 drives the second positioning sleeve 202 to move downward under the positioning of the mounting plate 6, and the positioning cylinder 2 moves through the limit of the first positioning sleeve 201, and the support skirt 203 supports on the sand to ensure the reliable positioning of the main body 1 of the sand quality improvement device. Then start the second lifting hydraulic cylinder 10, so that the second lifting hydraulic cylinder 10 drives the mounting cylinder 13 to move downward under the positioning of the upper cover plate 204. The positioning cylinder 2 performs active limit processing on the mounting cylinder 13. At the same time, the discharge branch pipe 1301 is also actively limited through the penetration with the mounting cylinder 13. Since the discharge branch pipe 1301 is always located in the feed hole 1104, when the screw conveyor 4 is started, the sand can be spirally conveyed into the screening drum 11. The screening drum 11 moves the sand to the screen 1103 under the drive of the rotating motor 12 and performs screening through the screen 1103. The motor support frame 8 is used for the reliable positioning of the rotating motor 12. The positioning collar 1101 cooperates with the auxiliary support roller 1102 to realize the reliable operation processing of the screening drum 11. After the sand is screened, it falls onto the sand again through the guiding of the guiding hopper 7. The screened impurities are discharged into the waste collection box 9 from the tail end. After opening the discharge control plate 901, they can be discharged uniformly. By controlling the descending depth of the mounting cylinder 13, the depth of the sand that needs to be improved in quality can be achieved. After the main body 1 of the sand quality improvement device improves the sand quality of one part, it moves continuously to ensure that the sand quality in each place is improved. During the movement of the main body 1 of the sand quality improvement device, the guiding slope 902 levels the sand, thus completing a series of operations.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
