Preferably, described cylindrical body is made up of the straight shape tube that an arc tube and that is positioned at the top is positioned at the below, and this arc tube inserts with tangential direction with the junction of this straight shape tube.
By above-mentioned to description of the present utility model as can be known, compared with prior art, the weighing hopper that the utility model is used for asphalt concrete regenerating equipment to the chute of a mixing bowl has following beneficial effect:
At first, the utility model is close at the external surface of cylindrical body and is provided with a conduction oil heat-insulation unit, has avoided asphalt-regenerating material Yin Wendu to descend causing viscosity to increase so that the undesirable condition that stops up chute takes place, and what guarantee to produce carries out in order;
Secondly, pipe-line system is the channel-section steel that opening is close to the cylindrical body external surface, and conduction oil can directly contact with the cylindrical body external surface, and heat insulation effect is guaranteed;
The 3rd, pipe-line system is coated with heat preservation rock outward, and heat preservation rock is coated with corrosion resistant plate outward, and heat waste is less, safety, efficient;
The 4th, the one side of asphalt-regenerating materials flow is provided with detachable liner plate in the cylindrical body, but after by the asphalt-regenerating grinding abrasion instantaneously changing liner plate, convenient for maintaining is avoided production is caused big adverse effect;
The 5th, cylindrical body is made up of the straight shape tube that an arc tube and that is positioned at the top is positioned at the below, arc tube can solve interference problems such as straight shape tube and pitch machine crossbeam, pipeline, the incomparable advantage of straight shape tube is especially arranged in the corner, simultaneously straight shape tube has advantages such as quick blanking again, the utility model designs in conjunction with the advantage of the two, insert with tangential direction in the junction of the two simultaneously, can eliminate at the two junction asphalt-regenerating material the direct impact of cylinder inboard wall, prolong the application life of chute.
