Description
Technical Field
The utility model relates to the technical field of stone test devices, in particular to a lateral discharging los Angeles abrasion tester.
Background
The los angeles abrasion tester mainly makes steel balls and aggregates rub and impact through steel cylinder rotation, measures the friction and impact resistance of coarse aggregates under standard conditions, and expresses the abrasion loss (%) as the abrasion loss.
The existing los angeles abrasion tester has the following defects: (1) the roller cover is fixed on the roller through four bolts, the nut needs to be unscrewed to take down the heavy roller cover in each test, the sample is placed into the roller, then the roller cover is covered, the bolts are screwed, and the process of opening and closing the roller is complex, time-consuming and labor-consuming. (2) The bolt and the nut are easy to slide and difficult to replace after being used for many times, and the later use is influenced. (3) After each test, the roller needs to be manually rotated to enable test piece residues to fall to the receiving tray along the roller opening, the receiving tray is manually cleaned, and the receiving tray is heavy, horizontally placed and located below the roller, so that the cleaning work consumes time and labor.
Because los angeles abrasion testing machine is drum-type, it is comparatively loaded down with trivial details to collect the sample. Generally, the feeding port is opened first, the steel ball is taken out, then the feeding port is fastened, the los Angeles abrasion instrument is rotated, the feeding port is inclined downwards, the material receiving disc is placed at the bottom of the feeding port to collect scattered samples, loss of the samples is difficult to avoid in the process, and the test precision is low.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model aims to provide the los angeles abrasion testing machine capable of discharging laterally, the roller can be inclined through the lifting device, so that materials in the roller can be conveniently and quickly converged into a screen through the side opening gate and the material guide slope, the labor amount of personnel is greatly reduced, meanwhile, the collection link of the material collecting disc is reduced, the sample loss is reduced, and the test accuracy is improved.
In order to achieve the purpose, the utility model adopts the following technical scheme.
A laterally-discharged los Angeles abrasion tester comprises a roller, a motor device and a lifting device, wherein the roller is supported on a side bracket through a roller rotating shaft, and an output shaft of the motor device is connected with the roller rotating shaft and used for driving the roller to rotate; the side of the roller is provided with a fan-shaped opening for loading and unloading. The roller, the motor device and the material guiding slope are fixed on the instrument base through a support. A certain gap exists between the material guiding slope and the roller, and the normal rotation of the roller is not influenced.
The side fan-shaped opening part is provided with an opening door, the opening door is controlled through a hinge shaft, and the hinge shaft is fixed on the side wall of the roller. The opening door is fixed by a buckle switch when being closed and opened.
This los angeles wearing and tearing testing machine discharge gate is provided with the guide slope, and the ejection of compact of being convenient for can be directly with the sample screen cloth of joining in, reduces the link that the material collecting disc was collected and then reduces the sample loss.
Compared with the prior art, the utility model has the advantages.
The laterally-discharging los Angeles abrasion testing machine can solve the problem that materials cannot be conveniently discharged after an asphalt mixture test is finished in a los Angeles abrasion testing device in the prior art, a roller can be inclined through a lifting device, so that the materials in the roller can be conveniently, quickly and easily discharged from a side discharge hole, the labor capacity of personnel is reduced, meanwhile, the situation that fine residual materials cannot be discharged in the roller to affect the test accuracy is also prevented, and the test accuracy is greatly improved.

Detailed Description
The technical solution of the present invention is further described in non-limiting detail with reference to the following examples and the accompanying drawings.
A basic structure of a los Angeles abrasion tester with lateral discharging.
As shown in figure 1, a lateral discharging los Angeles abrasion tester comprises a roller 1, a motor device 2 and a lifting device 10; the roller 1 is connected with a motor device through a rotating shaft 3; a fan-shaped opening gate 8 is arranged on the side edge of the roller 1; the opening door 8 is fixed by a buckle switch 9 when being opened and closed; a material guide slope 7 is arranged below the opening gate 8 to facilitate discharging; the left and right sides of the instrument base 10 are respectively provided with an inclination angle rotating shaft 5 and a hydraulic lifter 6; the roller 1, the motor device 2 and the material guiding slope 7 are all fixed on the instrument base 10 through a bracket 4.
