DETAILED DESCRIPTION

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.

The utility model provides a conveying device for concrete aggregates as shown in FIGS. 1 to 3, comprising two support frames 1 and a conveyor belt 2, wherein the two support frames 1 are used to support the conveyor belt 2, and the conveyor belt 2 is used to convey concrete aggregates, and the two support frames 1 cooperate with the conveyor belt 2 to make the conveyor belt 2 run under the action of a motor, which are all prior arts and are not described in detail here, and the conveyor belt 2 is located between the two support frames 1, and a drop gap is provided between both sides of the conveyor belt 2 and the corresponding support frames 1 for large aggregates to leave the conveyor belt 2, and the drop gap is provided for large aggregates in the concrete aggregates to pass through for centralized collection and treatment;

A filter plate 4 is movably provided above the conveyor belt 2. The filter plate 4 is in a V-shaped structure, and the conveyor belt 2 and the filter plate 4 fit together to filter the large aggregate in the concrete aggregate. One end of the conveyor belt 2 is the loading end, and the other end is the unloading end. The tip of the V-shaped structure of the filter plate 4 faces the loading end. The conveyor belt 2 is used to transport concrete aggregate. After passing through the filter plate 4, the concrete aggregate is divided into large aggregate and small aggregate on both sides of the filter plate 4. The large aggregate moves along the outer surface of the V-shaped structure of the filter plate 4 and then detaches from the conveyor belt 2. The small aggregate continues to be transported by the conveyor belt 2 after passing through the filter plate 4.

Specifically, the concrete aggregate is first conveyed to the loading end of the conveyor belt 2, and then the concrete aggregate is transported by the conveyor belt 2. During the transportation process, the large aggregate and the small aggregate in the concrete aggregate contact with the filter plate 4 together. After the small aggregate in the concrete aggregate passes through the filter plate 4, it continues to be transported to the unloading end of the conveyor belt 2, while the large aggregate in the concrete aggregate cannot pass through the filter plate 4. The large aggregate will move along the surface of the filter plate 4 under the transmission of the conveyor belt 2.

The two support frames 1 are fixedly connected with a protruding baffle 3 on one side close to each other. The protruding baffle 3 is fitted to the upper surface of the conveyor belt 2. The protruding baffle 3 is located on the side of the V-shaped structure close to the loading end, and is used to block the concrete aggregate that has just entered the conveyor belt 2 to prevent the concrete aggregate from scattering from the conveyor belt 2. A feeding gap is reserved between the protruding baffle 3 and the V-shaped structure for large aggregate to enter the dropping gap. When the large aggregate in the concrete aggregate falls into the dropping gap through the feeding gap, the large aggregate is removed from the conveyor belt 2.

A spring telescopic rod 5 is fixedly provided at the end of the protruding baffle plate 3, which has a telescopic characteristic. The telescopic rod 5 is telescopic when subjected to force, and one end of the spring telescopic rod 5 away from the protruding baffle plate 3 is fixedly connected to the filter plate 4. When the concrete aggregate contacts the filter plate 4, the spring telescopic rod 5 is telescopic when subjected to force, and the filter plate 4 vibrates under the elastic force of the spring telescopic rod 5 to avoid blockage of the filter plate 4 during the filtering process of large aggregate. The spring telescopic rod 5 is in a suspended state, leaving a gap between it and the conveyor belt 2 to avoid contact between the large aggregate and the telescopic rod 5 when passing through the feeding gap.

Specifically, when the concrete aggregate contacts the filter plate 4, the telescopic rod 5 is forced to expand and contract, and the filter plate 4 vibrates under the elastic force of the spring telescopic rod 5. Driven by the conveyor belt 2, the small aggregate in the concrete aggregate quickly moves through the filter plate 4, while the large aggregate in the concrete aggregate cannot pass through the filter plate 4. The large aggregate will move along the vibrated surface of the filter plate 4 under the transmission of the conveyor belt 2, and the large aggregate will enter the feeding gap and then fall from the feeding gap to the falling gap. At this time, the large aggregate is removed from the conveyor belt 2.

A large aggregate collecting hopper 6 is arranged below the conveyor belt 2. The large aggregate collecting hopper 6 is a rectangular box structure, which is used to collect the large aggregate after filtration and centrally process it. The upper end of the large aggregate collecting hopper 6 is open, and the opening is directly below the drop gap, so that the large aggregate can fall after being moved out from the conveyor belt 2. When the filtered large aggregate moves along the surface of the filter plate 4, it passes through the feed gap between the protruding baffle plate 3 and the filter plate 4, and then moves out from the conveyor belt 2, and falls from the drop gap between the support frame 1 and the conveyor belt 2 to the large aggregate collecting hopper 6 for centralized processing.
