Description

Technical Field

[0001] This utility model belongs to the technical field of conveying devices, and in particular relates to an aggregate conveying device for premixed concrete processing. Background Technology

[0002] Ready-mixed concrete refers to concrete mixtures that are centrally measured and mixed at a professional batching plant according to the design mix ratio, and then transported to the construction site for pouring within a specified time by concrete mixer trucks. In the production process of ready-mixed concrete, the raw materials need to be transported to the mixer through an aggregate conveying device.

[0003] However, during the process of conveying concrete aggregates, the aggregates fall from the conveyor belt. Due to uneven force or loss of guidance during the fall, the tension on both sides of the belt becomes unbalanced, causing the belt to deviate to one side. This results in the aggregates spilling due to the tilt in the falling direction, as well as the rollers getting stuck and the belt being damaged by friction. Utility Model Content

[0004] The purpose of this utility model is to provide an aggregate conveying device for ready-mixed concrete processing. By setting a limiting mechanism and an adjusting mechanism, it can not only guide and restrict the flow direction of aggregates during feeding and limit the scattering range of aggregates, thus preventing aggregates from spilling onto the edge of the belt or under the idlers, reducing idler jamming and belt friction damage caused by material spillage, but also adjust the position of the limiting arc plate according to the aggregate guiding requirements, forcing the material to fall vertically along the center line of the belt, reducing the interference of lateral force on the belt track, and avoiding unilateral accumulation that causes uneven load and deviation, thus solving the existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0012] Furthermore, the adjusting push plate is provided with a limiting slot inside, and a limiting block is provided on the top of the adjusting push plate, with the limiting block being fixedly fitted inside the limiting slot.

By fixing the limiting block inside the limiting sides, the adjusting push plate can be assembled together. The limiting slots are distributed in a linear array inside the adjusting push plate.
