Special loading device for lime-soil mixing

Abstract

The invention discloses a special loading device for lime-soil mixing, and belongs to the technical field of building construction equipment. The special loading device for lime-soil mixing comprisesa plurality of discharging bins arranged on a rack in parallel, wherein a screening mechanism for loosening soil is arranged on an inlet of each discharging bin; a stirring mechanism for loosening thesoil in each discharging bin for the second time is arranged on the bottom part of each discharging bin; and a metering and conveying mechanism for metering and conveying the soil is arranged under an outlet of each discharging bin. According to the special loading device for lime-soil mixing provided by the invention, the soil is loosened through each screening mechanism arranged on the inlet ofeach discharging bin in advance so as to be prevented from being blocked and accumulated on a feed inlet, the loosened soil is loosened for the second time on the bottom part of each discharging binthrough each stirring mechanism so as to be prevented from arching in each discharging bin to influence discharging, and the soil fallen from an outlet of each discharging bin falls to each metering and conveying mechanism so as to be metered and conveyed to a stirring station for stirring. By utilizing the special loading device for lime-soil mixing provided by the invention, the soil can be fallen smoothly, the burdening speed can be effectively improved, and the accuracy in metering the soil is ensured.

Description

technical field [0001] The invention belongs to the technical field of building construction equipment, and in particular relates to a special feeding device for lime-soil mixing. Background technique [0002] The construction quality of the high-speed railway subgrade directly affects the operation safety of the high-speed railway. The high-speed railway subgrade has high design standards, difficult construction, and especially high construction quality. In the prior art, high-speed railway foundations have the following requirements for improved soil filling construction: 1. The soil quality must be screened; At present, the stabilized soil mixing station is usually used for mixing in actual construction. However, the following problems occurred in the actual mixing process of improved soil: [0003] 1. The upper screen of the upper hopper is easy to block, accumulate, and unloading is not smooth; 2. After the soil material enters the interior of the hopper, because the ...

AI Technical Summary

Problems solved by technology

[0003] 1. The upper screen of the upper hopper is easy to block, accumulate, and unloading is not smooth; 2. After the soil material enters the interior of the hopper, because the structure of the hopper is an inverted cone, the upper opening is large and the lower opening is small, in large quantities, When the fast soil material passes through, it will be crowded and connected in the middle and lower part, forming an arched soil layer, which cannot be fed or intermittently fed, which will affect the passage of subsequent soil materials, thereby affecting the batching capacity; 3. Intermittent feeding, Or the impact of large groups of falling materials will cause inaccurate measurement of soil materials; 4. The actual effect is very low
