Description

Technical Field

[0001] The utility model relates to the technical field of density detection, in particular to a building block dry density testing device. Background Art

[0002] Currently, there are two main methods for testing the dry density of building materials: one is to cut the material into regular shapes, then measure its size to obtain the volume of the material, and further calculate the dry density; the other is to obtain the material volume through the drainage method, and then calculate the dry density.

[0003] The first method requires a special cutting machine, which is time-consuming and labor-intensive, and the cutting size is not accurate, which can easily cause deviations in volume calculations; the second method requires water. For materials with low density and water absorption, the drainage volume cannot be accurately obtained using the drainage method, and the true volume of the material cannot be calculated. The dry density of such materials is not suitable for measurement by this method, which is problematic. Utility Model Content

[0016] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] It should be noted that when an element is referred to as being “fixed to” another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

[0018] For ease of description, spatially relative terms such as "upper," "lower," "left," and "right" may be used herein to describe the relationship of one element or feature relative to another element or feature shown in the figures. It should be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation shown in the figures. For example, if the device in the figures is inverted, an element described as being "below" another element or feature would be positioned "above" the other element or feature. Thus, the exemplary term "below" can encompass both above and below orientations.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention.
