[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment 1: A feeding device for an asphalt mixing station, such as Figure 1-5As shown, it includes a concrete silo 1 which is transparent on the left and right, and a plurality of batching devices 2 are arranged at intervals on the left and right in the concrete silo 1, which are used to batch the aggregates according to the specified proportion. Specifically, the batching device 2 includes a plurality of storage bins 21 arranged at intervals in the upper and lower parts, and the bottom of the storage bin 21 is a conical structure with a gradually decreasing horizontal cross-section, so that most of the weight of the aggregates in the storage bin 21 is applied to the storage bin 21 where it is located, and a vibration motor 6 is fixed on the storage bin 21. The vibration motor 6 can prevent the aggregates from being blocked or stuck and accelerate the flow of the aggregates. An infrared sensor is arranged on the inner top of the storage bin 21 at the bottom, and the insufficient aggregates in the storage bin 21 can be detected in time through the infrared sensor, and a signal is sent to notify the staff to carry out the aggregate mixing. In addition, two adjacent storage bins 21 are connected by plugging, and the bottom of the upper storage bin 21 is inserted into the top of the lower storage bin 21 and extends into the lower storage bin 21. The top of the concrete bin 1 is provided with a plurality of through holes that are transparent from top to bottom. The top of the uppermost storage bin 21 is inserted into the through holes and is flush with the upper surface of the concrete bin 1. A measuring bucket 22 is provided at the bottom of the lowermost storage bin 21, and the bottom of the lowermost storage bin 21 is inserted into the measuring bucket 22. A conveyor belt 11 is provided below the measuring bucket 22, and the conveyor belt 11 is fixed to the inner bottom of the concrete bin 1; a bracket 23 is fixed to the bottom of the measuring bucket 22, and the bracket 23 is fixed to the inner bottom of the concrete bin 1.

[0027] A supporting device for independently supporting each storage bin 21 is provided in the concrete bin 1. Specifically, the supporting device includes a plurality of supporting rods 4 fixedly arranged in the concrete bin 1 and extending along the front-to-back direction. The supporting rods 4 are I-beams. The front and rear ends of the supporting rods 4 are respectively inserted into and pre-buried in the front and rear sides of the concrete bin 1. The plurality of supporting rods 4 are respectively located on the left and right sides of each storage bin 21. The left and right sides of the storage bin 21 are fixedly provided with a plurality of angle compensation brackets 3 arranged at intervals in front and back. The bottom of the angle compensation bracket 3 is a horizontal angle, and the angle compensation bracket 3 is fixed on the supporting rods 4. By arranging the supporting rods 4 on both sides of each storage bin 21 and supporting the conical side surface of the bottom of the storage bin 21 by the angle compensation bracket 3, it is possible to avoid the storage bin 21 located below from being subjected to excessive gravity load and causing risks. At the same time, the storage bin 21 with a tapered structure whose horizontal cross-section gradually decreases can apply most of the weight of the aggregate in the storage bin 21 to the storage bin 21, thereby avoiding excessive pressure on the aggregate located below, resulting in uneven batching and affecting the quality of the finished product.

A steel mesh plate 7 is fixedly provided on the top of the storage silo 21 located at the top. The cross section of the steel mesh plate 7 is larger than the through hole. The steel mesh plate 7 is located at the bottom of the silo, and the steel mesh plate 7 is pressed against the top of the concrete silo 1. The warehouse 8 can shield the top of the storage silo 21 at the top to prevent rainwater from directly entering the storage silo 21 at the top on rainy days; the steel mesh plate 7 can form a layer of protection between the silo and the storage silo 21 at the top to prevent workers from falling accidentally, and prevent large pieces of aggregate or other debris from entering the storage silo 21, and when the silo is full of aggregate, the steel mesh plate 7 can bear part of the pressure and transmit the pressure to the concrete floor silo 1 to prevent the storage silo 21 at the top from bearing too much gravity.

[0029] A triangular slope 9 is provided inside the silo, and the triangular slope 9 is fixedly cast in the warehouse 8. The triangular slope 9 makes the bottom of the silo present a structure with a cross-section gradually decreasing from top to bottom, which assists the aggregate in the silo to enter the storage silo 21; an anti-ridge 10 is provided at the bottom of the opening of the silo, and the anti-ridge 10 is fixedly cast on the top of the concrete silo 1. The anti-ridge 10 can prevent water outside the warehouse 8 from entering the silo, causing the aggregate in the storage silo 21 to become wet.

[0030] Working principle: When in use, the aggregate is shoveled into the silo by a forklift, and the aggregate in the silo is filled into multiple storage silos 21 from top to bottom in sequence. The storage silo 21 at the bottom transports the aggregate to the measuring bucket 22, and the measuring bucket 22 puts a specified amount of aggregate onto the conveyor belt 11 as required. The conveyor belt 11 transports the prepared aggregate to the mixing device through the bucket elevator to mix with the asphalt liquid.
