After filling, take the placing barrel out vertically to allow the cement to collapse on the board. Then, compare the highest point of the placing barrel and the concrete to obtain the slump of the concrete. Currently, when testing the slump, it is not convenient to measure the distance between the highest point of the concrete and the placing barrel. During measurement, the staff needs to manually pick up the concrete, which is prone to shaking during the picking process, resulting in data deviation.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] Example 1

A groove is provided at the lower part of the frame 1. By placing tools in the groove, the tools can be collected and stored for easy later retrieval. A testing platform 2 for concrete testing is provided on the upper part of the frame 1, and the testing platform 2 is a cube. The placing cylinder 3 for placing concrete is placed in the middle of the testing platform 2. An arc plate extends outward from the upper edge of the placing cylinder 3 to facilitate retrieval when the slump is measured. The guide hopper 25 is fixed to one side of the upper part of the placing cylinder 3. The guide hopper 25 gradually moves inward from top to bottom, so as to play a guiding role when the concrete is placed in the placing cylinder 3. It also includes a slide rail 4. The slide rail 4 is provided on the rear and left sides of the testing platform 2. A sliding frame 5 is slidably connected to the two slide rails 4. The sliding frame 5 slides back and forth on the slide rail 4 on the rear side, and the left side of the sliding frame 5 moves back and forth on the left slide rail 4. A scale 6 for measuring the slump of concrete is slidably connected to the sliding frame 5.

[0030] When the staff needs to use the device to test the concrete, the staff pours the concrete into the placement tube 3 through the guide hopper 25. After pouring, the staff pulls the sliding frame 5 backward, and the sliding frame 5 drives the scale 6 to move backward away from the placement tube 3. After the movement is completed, the placement tube 3 is pulled upward to make the concrete collapse on the surface of the testing platform 2. When the concrete no longer collapses, the staff moves the scale 6 so that the scale 6 is located on the edge of the concrete after the collapse, and then the scale 6 measures the size of the collapse, thereby achieving the purpose of facilitating the staff to detect the slump of the concrete. After checking, the staff cleans the concrete on the testing platform 2.

After taking it out, the staff pushes the bracket 13 downward, and the first elastic member 12 is squeezed and deformed, so that the bracket 13 drives the scraper 14 to move downward, and then the scraper 14 is stuck in the placing tube 3 to scrape the concrete on its inner wall, thereby facilitating the cleaning of the placing tube 3. After cleaning, the staff releases the bracket 13, and the first elastic member 12 drives the bracket 13 to move upward and reset, and then the staff moves the scale 6 to measure the concrete collapse data. After the measurement is completed, the staff starts the motor 15, and the output shaft of the motor 15 rotates to drive the rotary The movable rod 16 rotates, and the rotating rod 16 drives the roller 17 to rotate. The roller 17 drives the pull rope 18 to move forward, and the pull rope 18 drives the scraper plate 19 to move forward. The second elastic member 24 is squeezed and deformed, and the scraper plate 19 drives the concrete to move forward into the funnel 20, and then the concrete on the detection table 2 is scraped off, so as to achieve the purpose of automatically cleaning the concrete. The scraped concrete falls into the mold 22, and then the mold 22 collects the concrete. After scraping, the staff turns off the motor 15, and the second elastic member 24 drives the scraper plate 19 to move backward and reset. Then the staff pulls the baffle 26 to the left so that the baffle 26 no longer limits the mold 22. At this time, the staff pulls the mold 22 forward, takes out the concrete in the mold 22 and cleans it. After cleaning, the staff puts the mold 22 back to its original position and inserts the baffle 26 into the support frame 21 to limit the mold 22.
