Engineering material crushing and mixing system

Abstract

An engineering material crushing and mixing system comprises a soil block crushing device, a coconut coir block crushing device, a batching device and a screening device, wherein the soil block crushing device comprises a first stirring unit and a soil block crusher; the coconut coir block crushing device comprises material feeding volume adjusting units, a second material stirring unit and a coconut coir block crusher; the batching device comprises a third material stirring unit and material volume control units; and the screening device comprises a rotary screen and a screening hopper. The engineering material crushing and mixing system is high in automation degree, reliable in operation, and high in crushing efficiency; a matching unit is arranged, so that the material mixing and matching are made to be uniform; scrap iron adsorption units are adopted and the scrap iron mixed in the material can be adsorbed; and during the screening process, grain-sized material meeting the requirement is screened out through a screening material discharge port, and large-grain material is discharged through a material guiding box for reclamation.

Description

technical field [0001] The invention belongs to the technical field of material mixing, and in particular relates to an engineering material crushing and mixing system. Background technique [0002] Coconut peat is coconut husk fiber powder, which is a naturally degradable and pure natural organic medium that falls off during the processing of coconut husk fiber. Put the coconut peat that comes off during the processing of coconut shreds in the open air, and after being exposed to the sun and rain, reduce its salinity and conductivity. Coconut peat is very suitable for cultivating plants. When using coconut peat to cultivate plants After that, the root system of the plant grows very fast, which is conducive to the growth of the plant. 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. After processing, coconut peat usually needs to be compressed into blocks for...

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. After processing, coconut peat usually needs to be compressed into blocks for easy transportation, but it needs to be used. Crushed into powder, it is easy to mix with soil and sand to form a culture substrate. At present, manual crushing, mixing and sieving of coconut peat and soil blocks are generally used, which is time-consuming and laborious, and the existing crushing When the device crushes coconut peat and soil blocks, the crushing effect is not good. The crushed coconut peat and soil often have different particle sizes, resulting in uneven mixing of coconut peat, soil and sand, and the coconut peat and coconut peat It needs repeated back and forth crushing 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 effect and uneven mixing ratio. It is prone to material blockage and low working efficiency. The existing screening device has poor screening effect, and when there are too many large particles in the screen body, it needs to be shut down for manual cleaning, which increases labor intensity; in addition, the existing crushing device The broken structure is often in an integrated structure or is not easy to disassemble. When the broken structure is damaged, it cannot be used or it is difficult to replace the broken structure, resulting in a waste of resources.
