By setting the plug-in structure, when the two insertion rods are in the initial position, one end of the two insertion rods is inserted into the inside of the two insertion grooves, thereby supporting the rear part of the sliding plate through the two insertion rods to avoid shaking of the rear part of the sliding plate due to the absence of a support structure. After the concrete slump detection is completed, the moving structure is continuously operated, thereby extruding the two blocking blocks during the movement of the slump half-barrel, sliding the two vertical rods along the two limiting grooves, sliding the two insertion rods along the two circular grooves, and compressing the two springs two.

After each filling, the tamping rod 11 needs to be used to tamp the filled concrete, until the cavity between the two collapsed half barrels 3 is filled, and then the pouring hopper 7 is removed. At this time, the handle one 9 is rotated to drive the trowel plate 8 to rotate, so that the inclined surface of the trowel plate 8 trowels the concrete on the top of the two collapsed half barrels 3. At this time, the two motors 22 are started again to drive the two collapsed half barrels 3 to move away from each other, so that the concrete in the two collapsed half barrels 3 collapses due to gravity. At this time, the handle two 15 is rotated to ninety degrees, and then the two sliding blocks 17 are moved along the two fixed rod frames 16 to the vertical state, thereby driving the measuring ruler 14 to move to the vertical state. At this time, the measuring ruler 14 is slid down until the bottom of the measuring ruler 14 contacts the top of the collapsed concrete, and then the distance between the top of the collapsed concrete and the top of the collapsed half barrel 3 can be measured by the measuring ruler 14.

At this time, the top plate 32 moves downward because there is concrete on the top, and the four hollow cylinders 39 slide downward along the four top grooves 41, and the four springs 40 are compressed. However, the bottom of the top plate 32 is not in contact with the top of the sliding plate 31 at this time.

[0028] It should be noted that the present application is a kind of concrete detector, when using, directly place pouring hopper 7 at the top of two slump half-barrels 3, at this time, it can be filled by pouring hopper 7 to the inside of two slump half-barrels 3 three times, the adhesion state of two adhesion bands 12 is released, and the tamping rod 11 can be directly taken and used, after each filling, the tamping rod 11 is used to tamping the filled concrete, until the cavity between the two slump half-barrels 3 is filled, then the pouring hopper 7 is removed, at this time, rotate the handle 9 to drive the screed plate 8 to rotate, so that the slope of the screed plate 8 smoothes the concrete at the top of the two slump half-barrels 3, at this time, start two motors 22 to drive two slump half-barrels 3 to move away from each other, so that the concrete in the two slump half-barrels 3 collapses due to gravity, at this time, rotate the handle 15 to 90 degrees, then move the two sliding blocks 17 along the two fixed rod frames 16 to the vertical state, thereby driving the measuring ruler 14 to move to the vertical state, at this time, slide the measuring ruler 14 down until the bottom of the measuring ruler 14 contacts the top of the collapsed concrete, and the distance between the top of the collapsed concrete and the top of the slump half-barrel 3 can be measured by the measuring ruler 14, which is the slump degree of the concrete. The motor 22 is started to rotate the connecting shaft 28, and the two movable wheels 23 are rotated by the engagement of the two tooth grooves one 24 with the two tooth grooves two 25, thereby driving the two movable wheels 23 to rotate forward along the two sliding grooves two 20, thereby driving the connecting shaft 28 to move together and driving the slump half-barrel 3 to move forward through the connecting block 19, while the connecting shaft 28 moves, the motor 22 and the connecting frame 27 move together, and the connecting frame 27 slides forward along the two sliding grooves three 21 through the two sliding blocks 26; The output shafts of the two motors 22 rotate synchronously but in different directions, thereby driving the two slump half-barrels 3 to move away from each other, thereby causing the concrete in the two slump half-barrels 3 to collapse due to gravity, and thereby the subsequent concrete slump degree detection can be carried out; When the concrete slump test is completed, the fixed block 34 is pulled by the pull rod 33, and then the two resistance blocks 37 are moved forward until the distance inside the resistance block 37 is greater than the bottom diameter of the hollow cylinder 39, and the bottom of the hollow cylinder 39 is no longer in contact with the resistance block 37. At this time, the top plate 32 moves downward due to the concrete on the top, and the four hollow cylinders 39 slide down along the four top grooves 41, and the four springs 40 are compressed. However, the bottom of the top plate 32 is not in contact with the top of the sliding plate 31 at this time. At this time, continue to pull the pull rod 33, and when the front part of the knob 38 is in contact with the frontmost part of the embedded groove 36, pulling the pull rod 33 through the fixed block 34 to move the two resistance blocks 37 forward, the knob 38 is in contact with the embedded groove 36, and the sliding plate 31 is moved forward together, and then the top plate 32 is moved forward together through the four hollow cylinders 39. Because the front part of the top plate 32 is inclined, the front part of the discharge chute 30 is also inclined, so that when the top plate 32 moves forward, the front part of the top plate 32 is extruded by the front part of the discharge chute 30, and moves downward until the top plate 32 enters the through groove 29. At this time, the bottom of the top plate 32 is in contact with the top of the sliding plate 31, and the front part of the discharge chute 30 will scrape off the concrete on the top plate 32 when extruding the top plate 32. When the top plate 32 completely enters the through groove 29, the discharge chute 30 is in a completely open state, so that the concrete is discharged and falls through the discharge chute 30, and the collected concrete is collected by the external collecting device; When the concrete unloading and cleaning is completed, the above steps are reversed. When the top plate 32 moves to the inside of the discharge chute 30, the four springs 40 rebound, so that the top of the top plate 32 is again flat with the top of the bottom plate 1, and the top of the resistance block 37 is in contact with the bottom of the hollow cylinder 39, so that the hollow cylinder 39 does not slide down, and the top plate 32 is supported by the two resistance blocks 37. At this time, the slump test of the next batch of concrete can be started; When the outer surface of the slump half-barrel 3 is in contact with the blocking block 44, the motor 22 is stopped. At this time, the concrete slump test can be started, and the moving wheel 23 and the one end of the sliding groove 20 still have a reserved length. After the test is completed, the motor 22 is started again, so that the slump half-barrel 3 extrudes the two blocking blocks 44 during movement, and then drives the two vertical rods 46 to slide along the two limiting grooves 45 respectively, drives the two insertion rods 43 to slide along the two circular grooves 47 respectively, and the two springs 48 are compressed. The one end of the two insertion rods 43 is separated from the two insertion grooves 42 respectively, and the one end of the two insertion rods 43 is not in the inside of the discharge chute 30, so that the quick unloading structure 5 operates to unload and clean the concrete, and the falling concrete does not fall on the insertion rod 43, avoiding the insertion rod 43 from being unable to insert into the inside of the insertion groove 42 after being adhered to the concrete; When the two insertion rods 43 are in the initial position, one end of the two insertion rods 43 is inserted into the interior of the two insertion grooves 42 respectively, so that the rear part of the sliding plate 31 is supported by the two insertion rods 43, avoiding the shaking of the rear part of the sliding plate 31 due to the lack of support structure.
