Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete sampling, in particular to an asphalt concrete sampling device. Background Art
[0002] Concrete is an artificial stone material made by mixing cementitious materials, aggregates, water, and chemical admixtures and minerals when necessary, and hardening. In asphalt concrete testing, the workability of concrete refers to the performance of the concrete mixture being easy to operate (mixing, transporting, pouring, vibrating) and being able to obtain concrete of uniform quality and compact shape. Workability is a comprehensive technical indicator, including fluidity, cohesion and water retention. The fluidity, cohesion and water retention of concrete mixtures are interrelated and contradictory. If the cohesion is good, the water retention is often good, but the fluidity may be poor; when the fluidity is increased, the cohesion and water retention are often poor.
[0003] At present, when sampling for concrete workability testing, only the surface layer of concrete can be collected, or the surface concrete can be quickly removed to quickly take samples from the inside. Since the density of the aggregates of uncured concrete is large, it will settle downwards, and water will appear on the top. Then, the fluidity of the sample collected on the surface is bound to be greater than the true value. However, it is difficult to collect asphalt concrete inside.
[0004] Therefore, there is an urgent need to propose an asphalt concrete sampling device with simple structure and reliable sampling. Utility Model Content
[0005] In view of the above problems, the purpose of the present invention is to provide an asphalt concrete sampling device. The technical solution adopted by the present invention is as follows:
[0006] An asphalt concrete sampling device includes an outer sleeve, an upper nut seat and a lower nut seat welded to the inner wall of the outer sleeve, a sampling cup arranged at the bottom of the outer sleeve, a screw rod sleeved in the outer sleeve and threadedly connected to the upper nut seat and the lower nut seat, a baffle plate arranged at the bottom of the screw rod and placed in the sampling cup, a connecting rod arranged at the central bottom of the baffle plate, a conical head arranged at the bottom of the connecting rod, and a handle arranged at the top of the screw rod.
[0007] Furthermore, a scale is printed on the screw rod along the longitudinal direction.
[0008] Furthermore, a hand grip is sleeved on the upper portion of the outer sleeve.
[0009] Preferably, the total longitudinal length of the baffle and the connecting rod is less than or equal to the inner depth of the sampling cup.
[0010] Preferably, the upper diameter of the conical head is greater than or equal to the inner diameter of the sampling cup.
[0011] Preferably, the upper nut seat is welded to the top of the inner wall of the outer sleeve; and the lower nut seat is welded to the lower part of the inner wall of the outer sleeve.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] (1) The utility model provides a sampling cup, a baffle, a connecting rod and a conical head, and uses a screw rod for lifting and lowering adjustment to expose the lower opening of the sampling cup or close the lower opening of the sampling cup, so as to achieve sampling at a specified depth position of the asphalt concrete. It does not need to plane the surface layer of the asphalt concrete, and the sampling is simple and reliable.
[0014] (2) The utility model is provided with a conical head, which can cover the sampling cup when entering the asphalt concrete to prevent the asphalt concrete on the surface from entering the sampling cup, and can also ensure that it can enter the interior of the asphalt concrete reliably. After sampling, the sampling cup can also be covered to prevent part of the sample from leaking out.
[0015] In summary, the utility model has the advantages of simple structure, easy operation, reliable sampling, etc., and has high practical value and promotion value in the field of concrete sampling technology. BRIEF DESCRIPTION OF THE DRAWINGS

For example, A and / or B may represent three situations: A exists alone, A and B exist at the same time, and B exists alone.
[0025] The terms "first" and "second" in the description and claims of this embodiment are used to distinguish different objects rather than to describe a specific order of objects. For example, a first target object and a second target object are used to distinguish different target objects rather than to describe a specific order of target objects.
