Material mixing station for LID soil changing and filling engineering

Abstract

A material mixing station for LID soil changing and filling engineering comprises a coir block pulverizing system, a soil block pulverizing system, a proportioning system and a screening system. The material mixing station is high in automation degree and reliable in work. Coir blocks and soil blocks are respectively cut and pulverized by the coir block pulverizing system and the soil block pulverizing system, so that the material pulverizing effect is good, pulverizing efficiency is high, feeding amount is adjusted through a feeding amount adjusting device, material blockage is avoided, through the proportioning system, the materials are mixed and proportioned evenly, by a scrap iron adsorption device, scrap iron mixed in the materials can be adsorbed, by a third shifting device, accumulation of the coir blocks is avoided, therefore, the material mixing station works stably, the materials of which grain sizes meet requirements are screened from a screening discharge hole in a screening process, and large granular materials are discharged via a guiding box and is reused. By an anti-blockage device, the screening effect is good, and work efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of engineering material mixing, and in particular relates to a LID soil replacement engineering material mixing station. Background technique [0002] Low-impact development, referred to as LID, its full English name is LowImpactDevelopment, which is a rainstorm management and non-point source pollution treatment technology developed in the late 1990s. The control of runoff and pollution makes the development area as close as possible to the natural hydrological cycle. Low-impact development (LID) is an ecological technology system that can easily realize urban rainwater harvesting and utilization. The key lies in in-situ collection, natural purification, nearby utilization or recharge of groundwater. Low-impact development (LID) is a city that emphasizes maintaining and protecting the natural hydrological functions of the site, effectively alleviating the increase in flood peak flow caused by the increase ...

Problems solved by technology

In the process of using coconut peat as a culture substrate, it is necessary to mix coconut peat with soil and sand, and sieve it to meet the required particle size. At present, manual crushing and mixing of coconut peat and soil blocks are generally used. And screening, time-consuming and laborious, and when the existing crushing device is crushed coconut peat and soil block, the crushing effect is not good, and the crushed coconut peat and soil often have different particle sizes, resulting in coconut peat and soil and sand. The mixing is uneven, and the coconut peat and soil blocks need to be crushed back and forth many times to meet the requirements, which is easy to cause accumulation, affects the continuity of the crushing process, and also reduces the crushing efficiency

The existing proportioning device has poor mixing and proportioning effect, uneven mixing ratio, prone to material clogging, and low work efficiency. The existing screening device is prone to material clogging during the screening process, and the screening effect is poor , and when there are too many large particles remaining in the screen body, it needs to be shut down for manual cleaning, which increases the labor intensity
