Problems solved by technology

The transfer process of the dump truck is as follows: entering the hopper to pick up the material—opening the arc door of the hopper to discharge the material—closing the door after the dump truck is full—driving the dump truck away from the material receiving point to the concrete paving site—— Another dump truck enters the hopper to pick up the material - start the next cycle, the material transfer from the hopper to the dump truck is intermittent, if the belt conveying capacity is large, the unavoidable interruption of the material flow from the hopper to the dump truck will lead to It cannot be transferred out in time, due to the limitation of the transfer capacity from the hopper in the construction warehouse to the dump truck, which affects the speed of entering the warehouse of the roller compacted concrete conveying system

Embodiment 1

[0022] Such as figure 1 , figure 2 Among them, a concrete belt feeding and transferring device includes a belt feeding line 3, a hopper 1 is arranged under the belt feeding line 3, a plurality of discharge ports 7 are arranged under the hopper 1, and a plurality of discharge ports The port 7 is provided with a discharge door 4 .

[0023] The discharge door 4 is usually a hydraulic cylinder arc door.

[0024] According to the parameters such as the production capacity of the mixing plant, the conveying capacity of the feeding line, the construction strength, and the performance parameters of the dump truck, combined with the parameters such as the angle of repose of the RCC, the structure of the dump truck, and the discharge capacity, the opening and closing speed of the material door, and the material opening Due to the influence of arch plugs, it is designed and manufactured with 3 outlets on the left, middle and right, and a certain storage volume, the opening and closing...

Embodiment 2

[0027] A method for transferring concrete belts into warehouses, comprising the following steps:

[0028] A hopper 1 is set on the surface of the roller compacted concrete silo, and the hopper 1 is fed by the belt supply line 3, and three discharge ports 7 are set under the hopper 1, arranged according to the left, middle and right positions, and the three discharge ports Below the port 7, there are at most three rows of dump trucks 5 to supply the surface of the roller compacted concrete silo, and the concrete belt can be quickly transferred into the silo by the above-mentioned method.

[0029] In the optimized scheme, the inclination angle of the discharge port 7 located on the left and right sides is greater than the angle of repose of the concrete stream 6 . The distance between each discharge port 7 is greater than the width of the dump truck 5 . The distance between each discharge port 7 and the ground is greater than the height of the dump truck 5 .

[0030] Such as ...

Abstract

The invention relates to a concrete belt warehousing and transferring device and method. The device comprises a belt supply line, wherein a hopper is arranged below the belt supply line, a plurality of discharge ports are formed below the hopper, and discharge doors are arranged on the plurality of discharge ports and are hydraulic cylinder arc doors. According to the concrete belt warehousing and transferring device, by adopting the structure, the arrangement number of warehouse surface transfer hoppers is reduced, the hopper with three discharge ports can simultaneously carry out dumping operation on three dumpers, the transferring capability is about 3 times that of the hopper with single discharge port, the large dam pouring construction speed is increased, the warehouse surface equipment arrangement difficulty is favorably simplified, and the contradiction between a great amount of concrete continuous belt warehousing and interrupted conversion of hopper and dumper is solved.

Description

technical field [0001] The invention relates to the field of concrete conveying, in particular to a concrete belt feeding and transferring device for roller compacted concrete. Background technique [0002] In the construction of roller compacted concrete dams, belt feed lines, hoppers, and dump trucks are often used as the means of conveying RCC into the warehouse. The belt feed line transports a large amount of RCC to the hopper in the construction warehouse, and then the unloading of the hopper The material door is opened and closed to release the RCC material to the dump truck, and then transferred to the dam paving site by the dump truck, and the bulldozer will flatten the pavement according to the parameters required by the process. In the past, the hopper in the dam rolling construction warehouse had only one discharge port in the middle, and the belt feed line had a large conveying volume of RCC and continuously supplied materials. The dump truck opened through the d...
