And two ends of each square rod 16 are wound with a limiting spring 18, one end of each limiting spring 18 is fixedly connected to the square rod 16, and the other end of each limiting spring 18 is abutted against the end of the rack 54.

When the rack 54 is moved to make the mounting plate 41 abut against the two sliding plates 61 on one side of the platform 2, the end of the rack 54 will abut against the limiting spring 18 and make the limiting spring 18 compressed, the two sliding plates 61 will compress the corresponding pushing spring 17, and the magnet 62 on the sliding plate 61 will move to be separated from the iron block 72, so that the rotating plate 71 and the half cylinder 31 can be turned downwards for the next set of cement mortar to be measured.

When the pushing to the rack 54 is cancelled, the limiting spring 18 returns to the natural state and urges the rack 54 to move reversely, the rack 54 urges the mounting plate 41 to move away from the two sliding plates 61 through the gear 53 and the screw 51, and the pushing spring 17 returns to the natural state and urges the sliding plates 61 to slide and reset; two slides 61 in the same group of absorption subassembly 6 will contradict each other this moment, and when the rotor plate 71 upwards overturned, magnet 62 on two slides 61 will be able to adsorb the iron plate 72 on the rotor plate 71 to absorption subassembly 6 carries out spacing fixed to upset subassembly 7.

It should be noted that when the rack 54 is not subjected to the manual force and the thrust of the limiting spring 18, the rack 54 will be stationary on the square bar 16, and the gear 53, the lead screw 51 and the cleaning assembly 4 will also be stationary, so as to ensure the stability of the cleaning assembly 4.

The implementation principle of the cement mortar fluidity tester in the embodiment of the application is as follows: in the cement mortar measuring process, the bottoms of the two half cylinders 31 are abutted against the upper surface of the platform 2, and the cement mortar is placed in the shaping cylinder 3. When a worker pushes up the connecting rod 85, the two push rods 83 rise in the corresponding through holes 81, the two push disks 84 push the corresponding rotating plates 71 to turn upwards, the magnets 62 adsorb the iron blocks 72 on the rotating plates 71, so that the half cylinders 31 are separated from the platform 2, and the fluidity of the cement mortar can be measured.

When the pushing of the connecting rod 85 is cancelled, the two push rods 83 slide downwards due to self gravity, and the two push disks 84 are immersed into the corresponding counter bores 82, so that the push rods 83 are not easy to continuously descend, and the limit of the push rods 83 is realized.

After the fluidity measurement of the cement mortar is completed, a worker drives the rack 54 to slide on the square rod 16 through the handheld plate 55, the rack 54 drives the gear 53 and the screw rod 51 to rotate, the screw rod 51 drives the mounting plate 41 to axially slide along the limiting rod 52, and the scraper 42 and the brush 43 on the mounting plate 41 clean the cement mortar on the upper surface of the platform 2.

When the screw 51 drives the mounting plate 41 to separate from the upper surface of the platform 2, the mounting plate 41 will abut against the two sliding plates 61 on one side of the platform 2 and push the two sliding plates 61 to slide away from the corresponding rotating plates 71, the two sliding plates 61 will compress the corresponding push springs 17, and the end portions of the racks 54 will abut against the limit springs 18 and make the limit springs 18 compressed. The magnets 62 on the two sliding plates 61 are separated from the corresponding iron blocks 72, at the moment, the iron block 72 on each rotating plate 71 is only adsorbed by one magnet 62, the attraction force of one magnet 62 is insufficient, so that the rotating plates 71 and the half cylinders 31 are turned downwards due to the self gravity, and the next group of cement mortar is measured.

Then the limiting spring 18 will return to the natural state and urge the rack 54 to move reversely, the rack 54 will urge the mounting plate 41 to move away from the two sliding plates 61 through the gear 53 and the screw 51, the pushing spring 17 will return to the natural state and urge the sliding plates 61 to slide and reset; at this time, the two sliding plates 61 in the same group of the adsorption assembly 6 will interfere with each other. When the rotating plate 71 is turned upwards, the magnets 62 on the two sliding plates 61 can attract the iron blocks 72 on the rotating plate 71, so that the attraction component 6 can limit and fix the turnover component 7.

In summary, when the worker pushes up the connecting rod 85, the two half cylinders 31 are separated from the upper surface of the platform 2, so that the cement mortar flow rate can be measured. When the workman drives rack 54 through handheld board 55 and moves, can realize the clearance of the gluey sand of cement on platform 2 and the placing of a design section of thick bamboo 3 on platform 2 to the survey efficiency of gluey sand of cement has been improved.
