Description

Technical Field

[0001] The utility model relates to the technical field of mortar viscosity measurement, in particular to a mortar viscosity measuring device. Background Art

[0002] Mortar workability test is one of the key methods to study the fluidity of mortar. It can evaluate the operability and construction performance of mortar, which is of great significance for improving mortar proportion and optimization. Mortar workability refers to the flow performance and plasticity of mortar during construction, or in layman's terms, the ease of use of mortar. The workability of mortar is affected by many factors, such as the viscosity, viscosity, flow resistance, deformation ability, etc. The Stokes sphere method is used to measure the viscosity of mortar.

[0003] The Stokes ball method is a viscosity test method that uses the falling rate of a small ball in the mortar to evaluate the viscosity of the mortar. By calculating the falling rate of the small ball in the mortar, the viscosity and rheological parameters can be obtained. However, during the measurement process, the small ball in the container needs to avoid the viscosity measurement error caused by the unclear falling speed at different heights due to the tilt during the falling process. In addition, in this method, the mortar is easy to remain in the container and is not easy to clean, which will affect the subsequent viscosity measurement of the mortar. Therefore, this solution provides a mortar viscosity measurement device. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3The utility model provides a technical solution: a mortar viscosity measuring device, including a hollow tube 1 and a bottom cover 2, the top end of the hollow tube 1 is open, a longitudinal slide 3 is slidably installed on the inner wall surface of the hollow tube 1, a brush 4 is arranged on the end surface of the longitudinal slide 3 close to the inner wall of the hollow tube 1, a vertical rod 5 is fixedly inserted on the surface of the bottom cover 2 through a shaft sleeve, a round iron ball 6 is slidably installed on the vertical rod 5, a vertical through hole penetrating the upper and lower surfaces is opened inside the round iron ball 6, a wire rope 7 is fixedly tied on the outer surface of the round iron ball 6, a hanging ring hole 8 is fixedly installed on the outer surface of the bottom of the hollow tube 1, the end of the wire rope 7 passes through the hanging ring hole 8 and is wound to form a knot 9, and the knot 9 is used to prevent the round iron ball 6 from being completely dropped into the hollow tube 1 and being inconvenient to take out;

[0018] A stopwatch timer 11 is fixedly mounted on the outer surface of the hollow tube 1 through a bracket 10, and a striker 12 is inserted into the inner wall of the hollow tube 1. One end of the striker 12 passes through the hollow tube 1 and is connected to a touch switch in the stopwatch timer 11.

[0019] A scale 13 is fixed between the two stopwatch timers 11 , and the top and bottom of the scale 13 are at the same level as the two horizontal strikers 12 inside the hollow tube 1 .

[0020] A sealing gasket is provided on the outer surface of the hollow tube 1 through which the striker 12 passes, so as to prevent the mortar from leaking out from the gap between the striker 12 and the hollow tube 1 .

[0021] The bottom cover 2 and the hollow tube 1 are connected by a pipe sleeve, and an annular sealing ring 14 is provided at the connection between the bottom cover 2 and the hollow tube 1 .

[0022] Working principle:

[0023] In this solution, the hollow tube 1 is first sleeved on the bottom cover 2, and the annular sealing ring 14 on the outer surface of the bottom cover 2 is used to improve the tightness of the hollow tube and the bottom cover 2 after the sleeve connection;

[0024] Manually hold the end of the string 7 near the knot 9 and pull the string 7, so that the round iron ball 6 is pulled upward from the hollow tube 1 along the vertical rod 5, and the stirred mortar is poured into the hollow tube 1 through the funnel. The viscous mortar slowly falls in the hollow tube 1 until the hollow tube 1 is filled. Then the hand releases the string 7, and the round iron ball 6 slowly falls vertically on the uppermost surface of the mortar in the hollow tube 1. The vertical rod 5 prevents the round iron ball 6 from deflecting during the falling process in the mortar.

[0025] When the round iron ball 6 slowly falls in the mortar, it will touch the striker 12 in turn, so that the stopwatch timer 11 starts timing (the timing operation of the stopwatch timer 11 controlled by the striker 12 is ignored during the pouring and mixing of the mortar). The upper and lower height spacing difference between the two stopwatch timers 11 is a fixed distance, and the total length of the scale 13 is the height difference between the upper and lower horizontal strikers 12 in the hollow tube 1. The viscosity of the mortar is calculated by the falling speed and height;

[0026] After testing the viscosity of the mortar, pour the mortar out of the hollow tube 1. In this structure, the hollow tube 1 and the bottom cover 2 are socketed, and the bottom cover 2 can be manually removed from the bottom of the hollow tube 1. At this time, both ends of the hollow tube 1 are open, and clean water is used to flush the inside of the hollow tube 1 through an external spray head. During the flushing process, the longitudinal slide 3 can be manually held to slide around the top edge of the hollow tube 1. The top of the longitudinal slide 3 is buckled with the pipe mouth of the hollow tube 1. At this time, the brush 4 of the longitudinal slide 3 toward the inner wall of the hollow tube 1 brushes the inner wall of the hollow tube 1, and the sludge is cleaned with the clean water used for flushing to prevent the residual sludge from affecting the subsequent mortar viscosity measurement operation.
