Description
Technical field
The utility model relates to a kind of hot aggregate meausring apparatus of asphalt mixing plant, specifically a kind of door opener of hot aggregate.
Background technology
It is the metering of " accumulating " increment that hot aggregate in asphalt mixing plant weighs mode, four-point suspension.When carrying out aggregate and weighing, open successively to No. five bin gates from a bin gate, carry out increment weighing by the proportioning set in advance.Turn clockwise around axle because traditional bin gate is unified under the drive of cylinder, when No. four, No. five bin gate blowings time, in the process that bin gate is opened, some hot aggregate gets on aggregate weighing hopper right plate, a side knock is had to aggregate weighing hopper, make No. four, No. five weighings of expecting inaccurate, cause asphalt mixing ratio error to strengthen, directly affect the performance of whole asphalt.Meanwhile, because the hot aggregate of a part (mainly No. five material) does transverse movement when blowing, after working long hours, there will be the phenomenon of spreading.
Accordingly, how to solve that the hot aggregate of existing equipment weighs that inaccurate, mixing ratio error is large, the bad problem such as to be connected of spreading, door-opening mechanism cover and aggregate weighing hopper seeming necessary in the art.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of door opener of hot aggregate, and weighing precision can be made to improve, and increases assembly space, can effectively prevent spreading phenomenon again.
To achieve these goals, the door opener of a kind of hot aggregate of the utility model, comprise door-opening mechanism cover, be arranged on the multiple bin gates on door-opening mechanism cover, bin gate switching mechanism, and the aggregate weighing hopper be positioned at below bin gate, arranged on left and right sides bin gate passes through bin gate switching mechanism to aggregate weighing hopper intermediate symmetry blowing, the bin gate in described left side turns clockwise unlatchings under bin gate switching mechanism drives, and described right side bin gate rotarily opens counterclockwise under the drive of bin gate switching mechanism bin gate switching mechanism.
Further, described bin gate switching mechanism comprises cylinder, rocking arm, clamping plate, axle; Described one end and cylinder hinged, the other end welds with axle, bin gate by Boards wall on axle.
Further, described cylinder by shaft end ring bolt, shaft end ring and key and rocking arm hinged.
Further, described clamping plate and shaft connection place are provided with and adjust back-up ring and copper sheathing.
Further, described cylinder is band valve cylinder, saves space, easy to use.
The door-opening mechanism of hot aggregate is designed to Central Symmetry blowing form by the utility model, makes the hot aggregate fallen in aggregate weighing hopper be in its center, reduces the side knock to aggregate weighing hopper in stream dropping process, effectively improves the weighing precision of hot aggregate.Suitably can reduce door-opening mechanism cover lower ending opening size (in accompanying drawing, A is to size) simultaneously, facilitate the connection between cover and aggregate weighing hopper and solve its spreading problem.

Detailed description of the invention
In order to make those skilled in the art person understand the utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the door opener of the hot aggregate of the utility model, comprise door-opening mechanism cover 3, be arranged on the multiple bin gates 2 on door-opening mechanism cover 3, bin gate switching mechanism 1, and the aggregate weighing hopper 5 be positioned at below bin gate 2, arranged on left and right sides bin gate 2 passes through bin gate switching mechanism 1 to aggregate weighing hopper 5 intermediate symmetry blowing, the bin gate 2 in described left side turns clockwise unlatchings under bin gate switching mechanism 1 drives, and described right side bin gate 2 rotarily opens counterclockwise under the drive of bin gate switching mechanism 1 bin gate switching mechanism 1.
A kind of embodiment of above-mentioned bin gate switching mechanism 1 as shown in Figure 2, comprises cylinder 11, rocking arm 15, clamping plate 16, axle 19; Described rocking arm 15 one end is hinged by shaft end ring bolt 12, shaft end ring 13 and key 14 and cylinder 11, and the other end welds with axle 19, and bin gate 2 is fixed on axle 19 by clamping plate 16, and clamping plate 16 and axle 19 junction are provided with and adjust back-up ring 17 and copper sheathing 18.Wherein cylinder 11 is preferably band valve cylinder, saves space, easy to use.
When cylinder 11 is started working, it is with moving axis 19 to rotate by rocking arm 15, and axle 19 drives bin gate 2 to rotate around it by clamping plate 16 again, thus realizes the opening and closing of bin gate.
This door-opening mechanism adopts two ends bin gate to the mechanism form of intermediate symmetry blowing.When carrying out aggregate and weighing, two bin gates 2 in left side turn clockwise around axle under the drive of cylinder 11, and three bin gates 2 on right side are rotated counterclockwise around axle under the drive of cylinder 11.The hot aggregate that bin gate 2 opens each model rear falls aggregate weighing hopper 5 along aggregate weighing hopper center, ensure that the center of gravity of whole hot aggregate is in the center of scale hooper, effectively reduce the side knock to aggregate weighing hopper in dropping process simultaneously, improve weighing precision, ensure the accuracy of whole asphalt proportioning.Simultaneously because whole stream centrally falls position, door-opening mechanism cover 3 bottom size (namely in Fig. 2 A to size) can suitably reduce, and facilitates it to be connected when actual production with aggregate weighing hopper.This door-opening mechanism not only can improve the weighing precision of hot aggregate conscientiously, can solve again traditional spreading and install inconvenient problem.
