Embodiment 1

[0032] Such as Figure 1-5 As shown, a concrete dynamic segregation detection device includes a workbench 1, a material conveying assembly 2 and a material collection tank 3, and the workbench 1 is provided with two groups of material conveying assemblies 2 arranged up and down;

[0033] The material conveying assembly 2 includes a first mounting base 20, a second mounting base 21 and a material guide pipe 22. The first mounting base 20 and the second mounting base 21 are arranged opposite to each other on the workbench 1. The first mounting base 20 and the second mounting base 21 The workbench 1 is slidingly connected, and the second mounting base 21 is detachably connected with the workbench 1;

[0034] The guide tube 22 includes a first connecting section 220 and a second connecting section 221 that change the length of the overall guide tube 22 after being stretched relative to the axial direction. The first connecting section 220 and the second connecting section 221 corr...

Embodiment 2

[0044] Such as Figure 6-8 As shown, a slide bar 13 is fixedly connected to the second mount 21, and the slide bar 13 is arranged along the telescopic direction of the material guide tube 22. A limit block 14 is slidably arranged on the slide bar 13, and the limit block 14 is connected to the first mount seat 20. Fixed connection, the middle part of the limit block 14 has a sliding cavity 15, the sliding cavity 15 is provided with a sliding roller 16 used in conjunction with the slide bar 13, and three elastic rollers used in conjunction with the sliding roller 16 are arranged in a linear array on the slide bar 13. Raised 17. The limit block 14 can drive the first installation seat 20 to slide on the slide bar 13 through the sliding roller 16, and then the expansion and contraction of the first connecting section 220 can be adjusted. In addition, after the adjustment, the limit block 14 is located on the two elastic protrusions. Between the protrusions 17, the elastic protrus...

Abstract

The invention provides concrete dynamic segregation detection equipment which comprises a workbench, material conveying assemblies and a material collecting tank, the workbench is provided with the atleast two groups of material conveying assemblies which are arranged up and down, and each material conveying assembly comprises a first mounting seat, a second mounting seat and a material guide pipe; and the first mounting seat and the second mounting seat are oppositely arranged on the workbench, the material guide pipe comprises a first connecting section and a second connecting section, thelength of the whole material guide pipe is changed after the first connecting section and the second connecting section stretch out and draw back in the axial direction, the material collecting tank is formed in the workbench and located below a discharging port, and a detection assembly is arranged on the material collecting tank. According to the concrete dynamic segregation detection equipment,concrete at different heights can be conveyed for segregation detection, so that components of the concrete at different heights after segregation can be accurately detected, the reasonable proportion of the concrete is optimized, and the construction quality of subsequent concrete is improved.

Description

technical field [0001] The invention relates to the technical field of concrete mixing, in particular to a concrete dynamic segregation detection device. Background technique [0002] Concrete segregation is a phenomenon in which the cohesion between the constituent materials of the concrete mixture is insufficient to resist the sinking of the coarse aggregate, and the components of the concrete mixture are separated from each other, resulting in uneven internal composition and structure. The reasons for segregation may be pouring, improper vibration, excessive maximum particle size of aggregate, high proportion of coarse aggregate, low content of cementitious material and fine aggregate, and excessive density of coarse aggregate compared with fine aggregate. Large, or the mixture is too dry or too thin, etc. It will affect the pumping performance of concrete, cause sticking of tanks, blockage of pipes, affect the construction period, etc., and reduce economic benefits; aff...
