The outer surface of each rotating rod 7 is rotatably connected to a limiting block 8 near the top through a second bearing. The bottom of each limiting block 8 is bonded and connected with an anti-skid pad 9. The top of each rotating rod 7 is movable through the bottom of each anti-skid pad 9. The controller 210 is installed on the outer wall of the casing 6. The rotating plate 202 is above the funnel 4. The four connecting blocks 5 are divided into two groups, and the bottom of one group of connecting blocks 5 is on the same horizontal plane as the bottom of the collapse cone 3. The bottoms of the two anti-skid pads 9 are respectively in contact with the top of one group of connecting blocks 5.

[0026] The effect achieved is that when the slump of concrete needs to be detected, the concrete slump detection device is first placed on a stable ground, and then the controller 210 is connected to an external power supply, and then the controller 210 is turned on, and the use program is set. When everything is ready, the motor 209 is directly started by the controller 210. At this time, the output end of the started motor 209 will drive the connecting rod 208 and the first gear 206 to rotate together, and the rotating first gear 206 will drive the second gear 207 to rotate on the outer surface of the round rod 201 through the cooperation of the first bearing, and the rotating second gear 207 will drive the mounting plate 204 to rotate, and the rotating mounting plate 204 will drive the connecting rod 208 and the first gear 206 to rotate. The electric push rod 205 is driven to rotate. At the same time, the rotating electric push rod 205 will drive the rotating plate 202 to rotate on the round rod 201, and the rotating rotating plate 202 will also drive the laser ranging sensor 203 to rotate. When the rotating plate 202 rotates 90 degrees, the controller 210 is used to turn off the motor 209. Then, the funnel 4 is used to put the concrete that needs to be tested for slump into the interior of the slump cone 3 three times. After each injection of concrete, the injected concrete is compacted with the prepared tamping rod. Then, the funnel 4 is removed, and the excess concrete on the top of the slump cone 3 is scraped flat with the prepared scraper. Then, the slump cone 3 is pressed with another set of connecting blocks 5, and then the two limit blocks 8 are placed. After rotating 180 degrees, another set of connecting blocks 5 is used to lift the slump cone 3 vertically. At this time, the concrete inside the slump cone 3 will begin to collapse. When the concrete inside the slump cone 3 collapses completely, the controller 210 is used to start the motor 209, so that the rotating plate 202 drives the laser distance sensor 203 to reset and move back to the original position. Then, the controller 210 is used to turn off the motor 209, and then the electric push rod 205 is started. At this time, the telescopic end of the started electric push rod 205 drives the rotating plate 202 to move on the round rod 201, and the moving rotating plate 202 drives the laser distance sensor 203 to move. When the bottom of the rotating plate 202 just touches the highest point of the concrete after collapse, At this time, the controller 210 is used to close the electric push rod 205, and then the controller 210 is used to start the laser distance sensor 203. At this time, the laser distance sensor 203 will start to measure the distance between the bottom of the rotating plate 202 and the top of the workbench 1. Then the laser distance sensor 203 will transmit the measured distance data to the controller 210 in the form of an electrical signal. Then the controller 210 will directly display the received distance data on the screen of the controller 210 for the staff to watch. When the staff knows the height of the concrete after collapse, the height displayed on the controller 210 (the height after the concrete collapse) is directly subtracted from the height of the collapse cylinder 3 to obtain the accurate slump data of the concrete.

[0027] Working principle: When it is necessary to detect the slump of concrete, the concrete slump detection device is first placed on a stable ground, and then the controller 210 is connected to the external power supply, and then the controller 210 is turned on, and the use program is set. When everything is ready, the motor 209 is started directly by the controller 210. At this time, the output end of the started motor 209 will drive the connecting rod 208 and the first gear 206 to rotate together, and the rotating first gear 206 will drive the second gear 207 to rotate on the outer surface of the round rod 201 through the cooperation of the first bearing, and the rotating second gear 207 will drive the mounting plate 204 to rotate, and the rotating mounting plate 204 will drive the motor 209 to rotate. The electric push rod 205 rotates. At the same time, the rotating electric push rod 205 drives the rotating plate 202 to rotate on the round rod 201, and the rotating rotating plate 202 also drives the laser ranging sensor 203 to rotate. When the rotating plate 202 rotates 90 degrees, the controller 210 is used to turn off the motor 209. Then, the funnel 4 is used to put the concrete that needs to be slump tested into the interior of the slump cone 3 three times. After each injection of concrete, the injected concrete is compacted with the prepared tamping rod. Then, the funnel 4 is removed, and the excess concrete on the top of the slump cone 3 is scraped flat with the prepared scraper. Then, the slump cone 3 is pressed with another set of connecting blocks 5, and then the two limit blocks 8 are rotated. 180 degrees, and then use another set of connecting blocks 5 to vertically lift the slump cylinder 3. At this time, the concrete inside the slump cylinder 3 will begin to collapse. When the concrete inside the slump cylinder 3 has collapsed, the controller 210 is used to start the motor 209, so that the rotating plate 202 drives the laser distance measuring sensor 203 to reset and move back to the original position. Then, the controller 210 is used to first turn off the motor 209, and then the electric push rod 205 is started again. At this time, the telescopic end of the started electric push rod 205 will drive the rotating plate 202 to move on the round rod 201, and the moving rotating plate 202 will drive the laser distance measuring sensor 203 to move. When the bottom of the rotating plate 202 just touches the highest point of the concrete after the collapse, this The controller 210 is used to close the electric push rod 205, and then the controller 210 is used to start the laser distance sensor 203. At this time, the laser distance sensor 203 will start to measure the distance between the bottom of the rotating plate 202 and the top of the workbench 1. Then the laser distance sensor 203 will transmit the measured distance data to the controller 210 in the form of an electrical signal. Then the controller 210 will directly display the received distance data on the screen of the controller 210 for the staff to watch. When the staff knows the height of the concrete after collapse, the height displayed on the controller 210 (the height after the concrete collapse) is directly subtracted from the height of the collapse cylinder 3 to obtain the accurate slump data of the concrete.

[0028] Among them, the first bearing and the second bearing are commonly used in reality.

The model is selected according to the actual use, so the motor 209, the electric push rod 205, the laser ranging sensor 203 and the controller 210 are not explained in detail.
