As shown in Figure 1, a kind of Los Angeles Abrasion Test device convenient for discharging comprising have chassis 1, the first column 3, Two columns 4, roller 5, electric machine assembly 10,1 bottom of chassis are provided with multiple stabilizer blades 2, to stablize the experimental rig on support top. Noise is very big caused by due to the vibration of abrasion test device and by vibration, thus for stabilizer blade 2, preferably selection has and subtracts The structure and material of function are shaken, for example stabilizer blade 2 is made using yielding rubber material, or contain damping spring structure using interior Mechanical part.

In the one end on 1 top of chassis, it is provided with opposite thirty years of age of two columns, the first column 3 and the second column 4, first Column 3 and the setting of the second column 4 interval, and roller 5 is accommodated therebetween with setting up.First column 3 and the second column 4 use Plate-shaped member, it is preferred to use steel are made.Roller 5 is rotated around the roller shaft 8 being located among roller 5, and passes through roller Shaft 8 is supported on the first column 3 and the second column 4 at its both ends；In order to preferably support roller 5 to rotate, especially have Benefit, roller shaft 8 is by bearing support on the first column 3 and the second column 4.

The other end on 1 top of chassis is provided with the electric machine assembly 10 that driving roller 5 rotates, and electric machine assembly 10 is by being located at The electric machine assembly support 11 of its bottom is fixedly fastened on chassis 1.Electric machine assembly 10 is preferably composed with motor and reduction gearbox, Motor is exported into deceleration torque increase by reduction gearbox, and is connected by the output shaft 9 of electric machine assembly with roller shaft 8, and then drive Roller 5 rotates.

It is provided with conventional material opening on the circumferential wall of roller 5, material vent cover is provided in material opening, to object Material opening is closed and is sealed, to carrying out addition asphalt in roller 5；Particularly, in material vent cover It is provided with convenient for the handle 6 of operation material vent cover.

Asphalt and aiming at the problem that defective material inconvenience removal after the test in the prior art, the utility model is mentioned Effective solution scheme is gone out: on a part of section of the circumferential wall of roller, being obliquely arranged along the axial direction of roller There is the section 7 projected radially outwardly, as illustrated in fig. 1 and 2.The inner cavity of section 7 is connected to 5 inner space of roller, one end of section 7 Distance apart from 5 central axis of roller is equal to the radius of roller 5, and then along axial direction, section 7 is apart from 5 central axis of roller The distance of line constantly increases, and an inclined protrusion is finally presented.

Preferably, the distance of the central axis of the lateral extent roller 5 positioned at the second column 4 of section 7 is equal to roller 5 Radius, and it is axially extending along the direction of the first column 3 of direction, and the distance of central axis of the section 7 apart from roller 5 is increasingly Greatly, reach maximum on the side wall of the roller 5 and in the side for closing on the first column 3.In 5 side wall of roller for closing on the first column 3 On, and the position for corresponding to section 7 is provided with Dump gate 12, as shown in Figure 1.

When being tested using the experimental rig, asphalt is put into roller 5 by the material opening of roller 5 In, and check that Dump gate 12 is closed.Then starting electric machine assembly 10 drives roller 5 to rotate.After test period has arrived, stop electricity Then section 7 is turned to bottommost by the rotation of thermomechanical components 10, at this point, the asphalt of bulk and winged material fine crushing are all It slides and is stacked on the position of section 7；Then open Dump gate 12, by some conventional tools by asphalt and Defective material removal comes out, and does not need particularly to be removed to inside roller 5, simple to operation and will not have inside roller 5 The adhesion and deposition of material, can substantially reduce the workload of operator；It is clean since winged material fine crushing being weighed Removing roller 5 in winged material can effectively improve the accuracy of test.

For the ease of section 7 to be turned to the bottom of roller 5, it is highly preferred that the material vent cover and the area Section 7 is in centrosymmetric position on roller 5.Therefore, handle 6 can be turned to, then phase by the top by handle 6 Ground section 7 is answered to be located at the bottommost of roller 5.

It will be apparent to those skilled in the art that can make various other according to the above description of the technical scheme and ideas Corresponding change and deformation, and all these changes and deformation all should belong to the protection of the utility model claims Within the scope of.
