[0060] The application provides a construction method of the diamond paving construction cart, comprising the following steps:

[0061] S1: The diamond is contained in the storage box 2.

[0062] S2: The caking of the diamond is crushed by starting the crushing device.

[0063] S3: The conveying pipeline inputs the diamond in the storage box 2 into the distribution box 3.

[0064] S4: The diamond is screened through the sieve plate 31 in the distribution box 3. The small particle diamond meeting the design requirement is spread on the ground through the multiple discharge holes of the distribution box 3. The large particle diamond is left on the sieve plate 31.

[0065] S5: The driving device is started. The output shaft of the first motor 42 drives the sliding block to vertically slide in the sliding groove. The sliding rod 43 axially slides in the sliding hole, so that the sweeping brush 32 moves the large particle diamond to the opposite sides of the sieve plate 31 to avoid the large particle diamond from blocking the sieve plate 31.

[0066] S6: The base 1 is pushed, so that the small particle diamond is spread on the ground. The arc-shaped push plate 5 in the middle portion of the base 1 pushes the diamond accumulated on the ground to be flat. The rolling roller 61 of the pressing device flattens the ground and the diamond.

[0067] In the embodiment, the roller is an electric roller. The rear end of the base is arranged with a handle. The rear end of the base is formed with a pedal. The arc-shaped push plate and the flattening device are arranged below the pedal.

[0068] In construction, the operator stands on the pedal and moves the base by the electric roller to uniformly lay the small-grained diamond sand on the ground. When there is a little accumulation of diamond sand, the arc-shaped push rod at the rear end of the base can push the accumulated diamond sand flat, and then the diamond sand is flattened by the rolling roller, so that the surface of the terrace is flat.

[0069] The diamond sand paving construction cart can uniformly spread the diamond sand. Specifically, the diamond sand with large particles or wet clumps is cut and scattered by the crushing device, and then the diamond sand is transported to the distribution box through the conveying pipeline. After the diamond sand in the distribution box is screened by the screen plate, the diamond sand with uneven particle size is blocked above the screen plate, and the diamond sand with uniform particle size after filtration falls from the discharge port of the distribution box. With the movement of the base, the diamond sand is spread on the ground. The scraper on the roller scrapes the diamond sand adhered to the surface of the roller, and finally the arc-shaped push plate pushes the diamond sand on the ground flat, and then the diamond sand just pushed flat is flattened again by the rolling roller, so that the diamond sand is uniformly paved by the construction cart, and the road construction work efficiency is improved.

[0070] The diamond sand paving construction cart can uniformly spread the diamond sand, and when encountering uneven road surface, the arc-shaped push plate can drive the elastic push piece to contract and elongate, so that the arc-shaped push plate is lifted to facilitate the flattening work of the arc-shaped push plate.

[0071] The diamond sand paving construction cart can prevent the screen plate from being blocked by the diamond sand. The driving structure can sweep the large-grained diamond sand to the opposite sides of the screen plate by the sweeping brush, and the diamond sand blocked in the screen holes of the screen plate is brushed down, so that the screen plate is not blocked after a long time of use, and the spreading efficiency of the diamond sand is improved.

[0072] The diamond sand paving construction cart has anti-skid lines on the outer ring of the roller. When the roller rolls on the road surface, some diamond sand will adhere to the outer side of the roller, which will affect the rolling of the roller. The scraper can scrape the diamond sand on the outer side of the roller, the tension spring and the hinge shaft reduce the friction between the scraper and the roller, reduce the damage to the scraper, facilitate the rolling of the roller, and improve the utilization rate of the diamond sand and the practicability of the construction cart.

[0073] The above description is only the preferred embodiment of the present application and the explanation of the applied technical principles. Those skilled in the art should understand that the scope of the application involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, and also covers other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with the technical features disclosed in the present application (but not limited to) with similar functions to form technical solutions.
