[0022] Referring to Figures 1-4 , an embodiment provided by the present utility model: a concrete paver with adjustable scraper, which includes a paver body 1. A bracket 11 is fixedly installed on one side of the paver body 1 away from the operation handle. A power device 12 is fixedly connected to the upper end of the bracket 11. A mounting plate 13 is fixedly connected to the lower end of the bracket 11. An electric push rod 14 is fixedly connected to the side wall of the mounting plate 13 away from the operation handle. A push block 15 is fixedly connected to the output end of the electric push rod 14. Telescopic connecting rods 16 are fixedly connected to the non-adjacent side walls of the push block 15. One end of the telescopic connecting rod 16 away from the push block 15 is fixedly connected to a push rod 161. One end of the push rod 161 away from the telescopic connecting rod 16 is fixedly connected to a fourth connecting seat 17. A scraper body 2 is fixedly connected to one end of the bracket 11 away from the operation handle. First connecting seats 21 are fixedly connected to the non-adjacent side walls of the scraper body 2. Side plate assemblies 22 are arranged on the non-adjacent side walls of the scraper body 2. The side plate assembly 22 includes a side plate body 221. A second connecting seat 222 is fixedly connected to the side wall of the side plate body 221 close to the scraper body 2. The second connecting seat 222 is rotatably connected to the first connecting seat 21. A third connecting seat 23 is fixedly connected to the side wall of the side plate body 221 close to the paver body 1. The third connecting seat 23 is rotatably connected to the fourth connecting seat 17.

[0023] This setting starts the electric push rod 14, causing the electric push rod 14 to drive the push block 15 to slide linearly at the lower end of the bracket 11, causing the push block 15 to drive the telescopic connecting rod 16 to move linearly, causing the telescopic connecting rod 16 to drive the push rod 161 to move linearly, causing the push rod 161 to drive the fourth connecting seat 17 to move linearly, causing the fourth connecting seat 17 to pull the third connecting seat 23, and the fourth connecting seat 17 and the third connecting seat 23 rotate relative to each other, and the third connecting seat 23 rotates around the first connecting seat 21 as the center, thereby realizing the rotation of the side plate body 221, realizing the shape transformation of the scraping plate body 2 and the side plate body 221, and forming a push groove type.

[0024] A clamping groove 223 is provided at the upper end of the side plate body 221, a sliding groove 224 is provided on the side wall of the side plate body 221 away from the scraping plate body 2, a lengthening plate 225 is arranged inside the side plate body 221, the lengthening plate 225 is slidably connected with the sliding groove 224, an installation groove 226 is provided at the upper end of the lengthening plate 225, a spring 227 is arranged inside the lengthening plate 225, one end of the spring 227 is fixedly connected with the inner bottom wall of the installation groove 226, the other end of the spring 227 is fixedly connected with a limiting column 228, the limiting column 228 is slidably connected with the installation groove 226, and is used to press the limiting column 228, so that the limiting column 228 squeezes the spring 227, so that the limiting column 228 slides out of the clamping groove 223 and at the same time slides into the installation groove 226, and then after pulling the lengthening plate 225 to an appropriate position and making the installation groove 226 located directly below the clamping groove 223, then using the elastic force of the spring 227, the spring 227 pushes the limiting column 228 to snap into the clamping groove 223, thereby realizing the lengthening of the side plate body 221.

[0025] A baffle 18 is fixedly connected to the lower end of the mounting plate 13, and one end of the baffle 18 away from the mounting plate 13 is fixedly connected to the bracket 11, which is used to protect the electric push rod 14 and prevent concrete from splashing onto the surface of the electric push rod 14.

[0026] The height of the push block 15 is equal to the height of the mounting plate 13, realizing the sliding connection between the lower end of the push block 15 and the upper surface of the baffle 18, and the baffle 18 can be used to support the push block 15 to increase the movement stability of the push block 15.

[0027] A controller 3 is fixedly connected to the operating handle of the paver body 1, and the controller 3 is electrically connected to the electric push rod 14, which is used to control the start of the electric push rod 14 through the controller 3.

[0028] Both the installation groove 226 and the limiting column 228 are T-shaped, which is used to limit the limiting column 228 by the T-shaped shape to prevent the limiting column 228 from sliding out of the installation groove 226 directly due to the elastic force of the spring 227.

[0029] Working principle: First, start the electric push rod 14. The electric push rod 14 drives the push block 15 to slide linearly at the lower end of the bracket 11. The push block 15 drives the telescopic connecting rod 16 to move linearly. The telescopic connecting rod 16 drives the push rod 161 to move linearly. The push rod 161 drives the fourth connecting seat 17 to move linearly. The fourth connecting seat 17 pulls the third connecting seat 23, and the fourth connecting seat 17 and the third connecting seat 23 rotate relative to each other, and the third connecting seat 23 rotates around the first connecting seat 21, thereby realizing the rotation of the side plate body 221, realizing the shape transformation of the scraping plate body 2 and the side plate body 221, and making it form a pushing groove type. Secondly, the limit post 228 can be pressed. The limit post 228 squeezes the spring 227, and the limit post 228 slides out of the card slot 223 and at the same time slides into the installation slot 226. Then, after pulling the extension plate 225 to an appropriate position and making the installation slot 226 directly below the card slot 223, then using the elastic force of the spring 227, the spring 227 pushes the limit post 228 into the card slot 223, thereby realizing the lengthening of the side plate body 221.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. 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 for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
