Description

TECHNICAL FIELD

[0001] The utility model relates to mortar consistency detection field, concretely relates to a cement mortar consistency detection device. BACKGROUND

[0002] The consistency standard of road cement mortar is usually determined through mortar consistency test. The consistency of mortar refers to its fluidity, that is, the ability of mortar to be easily spread into a thin layer and fill the uneven places on the brick surface. The cement mortar consistency funnel detection method mainly involves pouring the uniformly stirred cement slurry into the discharge funnel until the slurry surface touches the lower end of the test rod (at this time, the slurry volume in the funnel is 1725ml), opening the control valve of the lower discharge port to make the slurry flow freely, and recording the time for the slurry to flow out completely as the consistency (fluidity) of the slurry.

[0003] However, in use, the test rod is fixed to the upper part of the suspended support rod, and the test rod is made of metal and is relatively heavy. Over a long period of time, the suspended support rod will be deformed and pressed down, causing the bottom of the test rod to change position and affecting the accuracy of the slurry volume in the funnel. The time for the slurry to flow out completely is calculated from the time the control valve is opened to the time the discharge port of the funnel can appear transparent. However, the naked eye observation of the transparent phenomenon is easily affected by light, causing inaccurate judgment of the time of appearance of transparency and affecting the calculation accuracy of the consistency.

[0017] The utility model will be described in further detail in combination with the drawings and specific embodiments:

[0018] As Figure 1 shown, a cement mortar consistency detection device, including lower discharge hopper 1, lower discharge hopper 1 top installation extends to its inside support rod 5, support rod 5 front end both sides fixed with support on the edge of lower discharge hopper 1 on stabilizing rod 8, support rod 5 screw connection has vertical test rod 7, support rod 5 is opposite lower discharge hopper 1's discharge port 2 central opening has the through hole, the through hole upper part is provided with laser range finder 11, the laser that laser range finder 11 hits is coaxial with discharge port 2 and is arranged, coaxial arrangement can guarantee the laser when the light of discharge port 2 penetrates laser range finder 2.

[0019] As Figure 2As shown, the stabilizing rod 8 is connected by the inclined rod 801 and the horizontal slide rod 802, the inclined rod 801 can form a triangular support with better stability, the inclined rod 801 is fixed on the front end side of the support rod 5, the slide rod 802 is sleeved with the adjustable sliding sleeve 9, the lower part of the sliding sleeve 9 is provided with the clamping sleeve 10 clamped on the top of the discharging hopper 1, the sliding sleeve 9 can change the position of the clamping sleeve 10, so that the stabilizing rod 8 can adapt to the discharging hopper 1 with different sizes and diameters.

[0020] As shown in Figure 1 , the control valve 3 is installed on the discharging port 2 at the bottom of the discharging hopper 1, the control valve 3 adopts a ball valve with better permeability, and the valve core will not be blocked after the ball valve is opened.

[0021] As shown in Figure 1 , the discharging hopper 1 is supported by the movable support frame 4 at the lower part, the support frame 4 is placed in the storage basin 11, the storage basin 11 is used to collect the cement slurry discharged from the discharging hopper 1, so as to avoid the spread of the slurry to pollute the environment; the outer end of the slide rod 802 is provided with a limiting block for limiting the falling of the sliding sleeve 9.

[0022] As shown in Figure 1 , the support rod 5 is clamped and arranged on the top edge of the discharging hopper 1 through the end clamping block, the outer side of the end clamping block is provided with the locking screw 6, and the locking screw 6 is convenient for dismounting and mounting the support rod 5.

[0023] The implementation principle of the cement mortar consistency detection device is:

[0024] Pour the uniformly stirred cement mortar into the discharging hopper 1 until the slurry liquid surface reaches the bottom of the test rod 7 to stop pouring (at this time, the slurry in the discharging hopper 1 is 725ml), open the control valve 3 of the discharging port 2 to make the slurry flow out freely, and open the stopwatch at this time to start timing;

[0025] At the same time of flowing out, the laser range finder 11 is opened, the laser range finder 11 will display the height from the liquid level in the discharging hopper 1 to the height of the support rod 5 on the display screen of the laser range finder 11, when the slurry in the discharging hopper 1 is completely discharged and the discharging port 2 appears to be transparent and transmits light, the laser of the laser range finder 11 will pass through the coaxial discharging port 2, and the height from the liquid surface in the lower storage basin 12 to the support rod 5 is B (as shown in Figure 3 , when the height B value is far more than the height A value from the support rod 5 to the control valve 3 (the height A value is the distance height measured by the laser range finder 11 before the experiment detection in the closed state of the control valve 3), it is judged that the discharging port 2 appears to be transparent, which means that the discharging of the discharging hopper 1 is completed, and the stopwatch can be closed to end timing, and the time obtained by the stopwatch timing is the consistency (flowability) of the slurry, so that the detected data is more accurate, and it is not necessary to observe and operate according to the human eye, and the accuracy of detecting the consistency of the slurry is better;
