[0002] The consistency of cement mortar is different from the general concept of "thinness and thickness". The consistency of cement mortar indicates "fluidity", which refers to whether the mortar is easy to flow under its own gravity or external force. Its size is expressed by the sinking value, that is, the depth in millimeters of the cone of the cement mortar consistency meter sinks into the mortar. The greater the consistency measured by the cement mortar consistency meter, the greater the fluidity, that is, the greater the depth of the cone sinking, the greater the consistency and the better the fluidity.

It should be understood that the embodiments shown in the accompanying drawings are not intended to limit the scope of the present invention, but are only intended to illustrate the essential spirit of the technical solution of the present invention.

[0030] The present embodiment provides a cement mortar consistency testing device, comprising a base 1, a dial 2, a measuring container 3, and a test cone 4; a side rod 12 is provided on one side of the base 1; the dial 2 is slidably provided on the side rod 12, a measuring pointer 201 and a measuring component are provided on the dial 2, and the measuring component is connected to the measuring pointer; the measuring container 3 is provided on the base 1 and is located below the dial 2; the test cone 4 is slidably provided on the side rod 12 and is located between the dial 2 and the measuring container 3.

[0031] As a preferred embodiment, the test cone 4 is made of steel or copper, the height of the test cone should be 145 mm, and the diameter of the cone bottom should be 75 mm;

[0032] As a preferred embodiment, the measuring container 3 is made of a steel plate, and the shape of the measuring container 3 can be set to be rectangular;

[0033] As a preference, the outer shape of the measuring container 3 may be rectangular, and the inner shape may be conical, the height of the conical tube is preferably 180 mm, and the inner diameter of the cone bottom is preferably 150 mm.

[0034] Specifically, a limit frame 10 is further provided on the periphery of the measuring container 3. The limit frame 10 plays a role of fixing and tightening the measuring container 3 during the vibration process, thereby preventing the measuring container 3 from tipping over due to excessive vibration amplitude during the vibration process.

[0035] Specifically, the measuring assembly includes a rack measuring rod 202 and a gear 203; the gear 203 is arranged at the back center of the dial 2, and the gear 203 is connected to the measuring pointer 201;

[0036] The rack measuring rod 202 is arranged on the back side of the scale plate 2 , and the rack measuring rod 202 is meshed with the gear 203 .

[0037] Specifically, a vibration assembly is provided at the bottom of the measuring container 3; the vibration assembly includes a placement plate 5, a limit plate 6 and a vibration motor 7; a plurality of limit rods 501 are provided at the bottom of the placement plate 5, and the top ends of the plurality of limit rods 501 pass through the through holes on the placement plate 5 and are connected to the limit plate 6, and a shock-absorbing spring 502 is provided on the outer side of the outer wall of each limit rod 501, and the shock-absorbing spring 502 is located between the base 1 and the placement plate 5; the vibration motor 7 is located at the bottom center position of the placement plate 5.

[0038] Specifically, a first slider 8 is provided on the side rod 12, and the first slider 8 is connected to the dial 2 through a connecting rod; a second slider 9 is provided on the side rod 12, and the second slider 9 is located below the first slider 8, and the second slider 9 is connected to the test cone 4 through a connecting rod.

[0040] When in use, the staff puts the mortar mixture into the measuring container 3 at one time, and the mortar surface is preferably 10mm lower than the container mouth, and starts the vibration motor. The vibration of the vibration motor drives the placement plate 5 to vibrate upward or downward. The placement plate 5 vibrates upward or downward so that the placement plate 5 compresses the shock-absorbing spring 502. The shock-absorbing spring rebounds after being compressed, thereby playing a buffering and shock-absorbing effect on the device. The limit plate 6 prevents the placement plate 5 from being separated from the limit rod 501 during the upward or downward vibration process; the device plays a role in leveling the cement mortar in the measuring container, better testing the consistency of the cement mortar, and improving the accuracy of the test results;

[0041] After the mortar surface in the measuring container is flat and compacted, unscrew the brake screw on the second slider 9, and move the test cone connected to the second slider downward. When the tip of the test cone just touches the mortar surface, tighten the brake screw so that the lower end of the rack measuring rod just touches the upper end of the sliding rod 11, and align the test pointer to the zero point;

[0042] Unscrew the brake screw on the second slider 9 to allow the test cone to continue to move downward and measure the time. Tighten the screw immediately within a certain period of time (preferably 10 seconds) to make the lower end of the rack measuring rod contact the upper end of the sliding rod 11. Read the sinking depth from the dial (accurate to 1 mm), which is the consistency value of the mortar.

[0043] The device improves the accuracy of cement mortar consistency testing, is beneficial to reducing the error of the test value and obtaining more accurate figures, improves the accuracy of consistency testing, reduces manpower and material resources, and has strong practicality.
