Description
Technical field
The utility model belongs to bulk density detection technique field, in particular to a kind of for detecting coarse aggregate bulk density
Experimental rig.
Background technique
Coarse aggregate bulk density is detected and is tested, it is desirable that coarse aggregate freely falls into appearance from the surface 5cm of capacity tube
Graduated cylinder.However rely primarily on artificial estimated distance during test at present and fallen into coarse aggregate in cylinder from certain altitude with spade,
In this way since artificial error can generate certain influence to test result.Therefore, it is necessary to one kind to be suitable for detection rough set material heap
The device of product density, and application method should be as economic, practical, convenient as possible, quick.
Utility model content
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of for detecting coarse aggregate accumulation
The experimental rig of density, by support rod, fixed frame, bearing platform, Weighing system, display system, capacity tube, movable platform, dress
Funnel and fixing bolt are constituted, wherein
The capacity tube is located on the Horizontal load-bearing platform of experimental rig bottom, and the bearing platform lower part connection weighs system
It unites and passes through display system output data；
The charging hopper is fixed in movable platform and adjusts charging hopper bottom by the vertical motion of movable platform
The distance between the dodge gate and capacity tube in portion；The movable platform is anchored fixed frame by fixing bolt and realizes that position is fixed；
The dodge gate of the charging hopper bottom is opened and closed by motor control；
The support rod is vertically arranged and is provided with scale, and the cross tube of upper end Connection Bracket, it is flat that lower end connects load-bearing
Platform.
Preferably, it is provided with stop bail on the vertical bar of the fixed frame, as the movable lower limit of movable platform, bail is high
At least 5cm at the top of capacity tube.
Preferably, the capacity tube is straight barrel type device for volume measurement, and the charging hopper lower part is butt wide at the top and narrow at the bottom
Conical hopper, small bottom faces of the dodge gate as frustoconical.
The utility model leads to by by making funnel be fixed on exact height as needed with graduated support rod
The dodge gate for crossing funnel bottom makes coarse aggregate free-falling, to can guarantee coarse aggregate from higher than capacity tube to the full extent
It is freely fallen at 5cm, avoids human error, be capable of the accuracy of guarantee test, and test principle is simple, easy to operate, warp
It helps practical.
Detailed description of the invention
Fig. 1 is the structural schematic diagram for detecting the experimental rig of coarse aggregate bulk density.
Description of symbols:
1- support rod, 2- bearing platform, 3- weighing system, 4- display system, 5- capacity tube, 6- movable platform, 7- charging
Funnel, 8- dodge gate, 9- fixing bolt, 10- fixed frame.
Specific embodiment
To make those skilled in the art more fully understand the technical solution of the utility model, below with reference to embodiment to this
A kind of experimental rig for detecting coarse aggregate bulk density that utility model provides is described in detail.Following embodiment is only used
In the range for illustrating that the utility model rather than limits the present invention.
It is a kind of for detecting the experimental rig of coarse aggregate bulk density, by support rod, fixed frame, bearing platform weighs system
System, display system, capacity tube, movable platform, charging hopper and fixing bolt are constituted.Capacity tube is located at the water of experimental rig bottom
On flat bearing platform, bearing platform lower part connects Weighing system and passes through display system output data；Charging hopper is fixed on
Adjusted in movable platform and by the vertical motion of movable platform between the dodge gate and capacity tube of charging hopper bottom away from
From；Movable platform is anchored fixed frame by fixing bolt and realizes that position is fixed；The dodge gate of charging hopper bottom passes through motor control
System folding.Support rod is vertically arranged and is provided with scale, the cross tube of upper end Connection Bracket, and lower end connects bearing platform.Gu
Determine to be provided with stop bail on the vertical bar of frame, as the movable lower limit of movable platform, bail is higher than at least 5cm at the top of capacity tube.
Capacity tube is straight barrel type device for volume measurement, and charging hopper lower part is frustoconical funnel wide at the top and narrow at the bottom, and dodge gate is as butt
The small bottom faces of taper.
Embodiment 1
Referring to Fig. 1, a kind of experimental rig for detecting coarse aggregate bulk density of the utility model includes with graduated
Support rod 1, fixed support rod fixed frame 10, can along the movable platform 6 that support rod moves up and down, be fixed in movable platform
Charging hopper 7, bearing platform 2, the bearing platform charging hopper bottom openable dodge gate 8, be connected with supporting rod
On Weighing system 3, the mobile fixing bolt 9 of display system 4, capacity tube 5, control movable platform.
Specific implementation step is described as follows:
It selects suitable capacity tube to be placed on the weighing system of bearing platform according to the specification of coarse aggregate, reads capacity tube
Weight.Bolt is unscrewed, movable platform is moved to along support rod by a certain scale according to code requirement, guarantees funnel dodge gate and holds
Cylinder head distance is 5cm, tightens bolt, fixed movable platform.The dodge gate for closing funnel bottom is scooped up slightly with tack spade
Gather materials and pour into charging hopper, opens dodge gate after funnel is full, making to gather materials freely falls into capacity tube, so several times, until
Gather materials and finally fills capacity tube.The artificial particle for removing protrusion nozzle surface, and gap is inserted with suitable particle, make protrusion with
Depressed section is generally equalized, reads cylinder by display system and adds the weight gathered materials.
The utility model accurately controls charging height for measuring road surface coarse aggregate bulk density, by scale, excludes people
For the influence of factor, so that testing result is accurate and reliable, compensating for detection coarse aggregate bulk density can only substantially estimate that charging is high
The deficiency of degree, it is easy to operate, it is economical and practical.
It is explained in detail above in conjunction with example of the embodiment to the utility model, but the utility model is not limited to
Example is stated, within the knowledge of a person skilled in the art, the utility model aims can also not departed from
