The quality of construction performance affects both the progress of construction and the final performance of the product. The fluidity of the coating has a great influence on the construction performance of the coating, so it is very important to control the fluidity of the coating within an ideal range.

The combination of the measuring tube and the measuring scale can be used to characterize the fluidity of coatings with higher viscosity, as well as the fluidity of coatings with lower viscosity. This fluidity measuring device can not only greatly save the time of the entire experimental process, but also reduce the error of the entire experiment.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0023] Reference Figure 1-4 The utility model discloses a material fluidity testing device, comprising a base 1 and a test seat 2, a flow groove 5 is provided on the top of the test seat 2, the base 1 and one end of the test seat 2 are hinged, an adjustment mechanism is provided between the base 1 and the test seat 2, the adjustment mechanism comprises a support rod 3 with one end rotatably connected to the middle part of the test seat 2, the other end of the support rod 3 is abutted against a support groove 4, and a plurality of support grooves 4 are evenly provided on the top of the base 1.
[0024] The test seat 2 is a rod-shaped structure, and the flow groove 5 is opened along the length direction of the test seat 2. The test seat 2 rotates around the hinged end, and the material to be tested is poured from the top of the flow groove 5 to observe its flow effect. It can be used to detect the fluidity of fluid materials, such as mortar, coatings, powders and other materials.
[0025] The cross section of the flow channel 5 is V-shaped.
[0026] The V-shaped groove can effectively reduce the amount of test materials used during testing compared to rectangular, circular and arc-shaped grooves, and is also convenient for cleaning after each test.
[0027] Scale lines 12 are provided on the side wall of the test seat 2 along the extension direction of the flow slot 5 .
[0028] The graduation marks 12 facilitate reading of the flow distance of the material.
[0029] A rotatable feeding funnel 6 is provided at one end of the test seat 2 away from the hinge, and the feeding funnel 6 is located directly above the flow slot 5 .
[0030] When in use, pour a certain amount of material into the feeding funnel 6, and the material flows from the feeding funnel 6 into the flow groove 5, and flows from top to bottom in the flow groove 5. The feeding funnel 6 is larger at the top and smaller at the bottom, and the radial size of the opening at the top of the feeding funnel 6 is larger than the width of the flow groove 5, which is convenient for adding material into the flow groove 5.
[0031] A rotating shaft seat 9 is arranged on the side wall of the test seat 2, and a rotating shaft 10 is arranged inside the rotating shaft seat 9. The axis of the rotating shaft 10 is perpendicular to the extension direction of the flow groove 5. One end of the rotating shaft 10 is connected to the outside of the feed funnel 6, and the other end is arranged with a connecting rod 8. A counterweight block 7 is arranged at the end of the connecting rod 8 away from the rotating shaft 10.
[0032] The feed funnel 6, the rotating shaft 10, the connecting rod 8 and the counterweight 7 are fixedly connected, and the rotating shaft 10 and the rotating shaft seat 9 are rotatably connected via a bearing. The mass of the counterweight 7 is greater than the total mass of the feed funnel 6 and the material when the material is added to the feed funnel 6. The counterweight 7 is acted upon by gravity to drive the feed funnel 6 to always be in a vertically upward state, thereby avoiding the situation in which the accuracy of the fluidity value is affected due to the different flow velocities when the material flows from the feed funnel 6 into the flow groove 5 due to the synchronous tilting of the feed funnel 6 with the test seat 2.
[0033] Since the feed funnel 6 is rotatably connected to the test seat 2, the corresponding positions of the feed funnel 6 and the flow trough 5 (the position of the landing point when the material flows from the feed funnel 6 to the flow trough 5) are slightly different after each angle adjustment. Therefore, after each angle adjustment, the distance to the landing point can be measured according to the scale line 12, and the distance can be subtracted when recording and comparing the fluidity values at different angles to reduce the error.
[0034] A receiving groove 11 is provided at the bottom of the test socket 2 , and the bottom of the receiving groove 11 is open.
[0035] The storage groove 11 is located on the rotation track of the support rod 3. The support rod 3 is U-shaped as a whole. The top of the support rod 3 is rotationally connected to the test seat 2. When use is over, the support rod 3 is rotated so that the cross bar at the bottom of the support rod 3 is stored in the storage groove 11.
[0036] Working principle: When in use, lift the test seat 2, rotate the support rod 3, and place the bottom end of the support rod 3 against the support groove 4, so that the test seat 2 maintains a certain inclination angle, and pour a certain amount of the material to be tested into the feed funnel 6. The material to be tested flows from the feed funnel 6 into the flow groove 5, and flows downward from the upper end of the flow groove 5. The fluidity value at the inclination angle is measured according to the scale line 12.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
