摘 要

城市绿化过程中，每年都会修剪下大量的树枝，修剪下的树枝形状各异、大小不等、粗细不均，收集整理十分不便。由于树枝蓬松，运输效率低，费时又费力，而且运输安全性差。而运出的枝桠，部分被送到垃圾场，部分被烧掉。虽然树枝处理了，但污染了环境，浪费了人力物力。因此枝桠处理不但是令市政府部门头疼的问题，也是工厂、学校、小区、果园等每年都要面临的问题。

将树枝就地粉碎削片再储存在一个大容量的料仓里，不仅可以节省运输成本、减少树枝堆积用地、净化环境，削片粉碎后的枝叶碎渣还可以用于生产有机堆肥，改良土壤，进行循环利用；或加工成制浆造纸和生产人造板所需的工艺木片；或进行粉碎后循环利用，制作成了压缩燃料块或作为裸露地覆盖物，能变废为宝。近年来，树枝削片粉碎处理悄然兴起，带动了储存料仓的发展，其中运用螺旋叶片实现了进料和出料的功能，这不仅大大改变了以往人力处理枯枝落叶的模式、加快了树枝树叶的处理速度，而且节省了费用，还减轻了工人的劳动量，成了枝桠处理的必然趋势。

因此，在研制树枝粉碎粉碎机的同时，为了提高枝桠处理效率、扩大枝桠的用途、提高枝桠的利用率、节约资源、美化环境，对于粉碎车料仓系统的设计也是必不可少的。

Abstract

Urban greening process, every year under a lot of pruning branches, trim branches under different shapes, sizes, thickness uneven, collected very inconvenient. Because branches fluffy, low transport efficiency, time-consuming and laborious, and poor transportation safety. And out of the branches, some were sent to landfills, some were burned. Although the branch to deal with, but the pollution of the environment, waste of manpower and resources. Therefore, treatment is not only to make the branches municipal government departments headaches, problems are factories, schools, community, orchards faced every year.

    The branches on the spot and then crush shavings stored in a large-capacity silos, not only can save transportation costs, reduce branch stacking space, cleaning up the environment, leaves crushed slag chippers can also be used in the production of organic compost, soil , for recycling; or processed into pulp and paper and wood production of wood-based panels process required; or crushed recycled, made into fuel pellets or compressed as bare ground cover, turning waste into treasure. In recent years, branch chippers pulverized sprung up, led the development of the storage silo, which use helical blade to achieve a feed and discharge of the function, which not only greatly changed in the past of human handling litter mode to speed up the branches the processing speed of the leaves, but also saves costs, but also reduce the amount of labor workers, has become an inevitable trend in the processing branches.

    Thus, in the development branch crushing mill, while the branches in order to improve efficiency and expand the use of branches, branches to improve efficiency, saving resources, landscaping, car silos for ground system design is essential.

Keywords: silo; large capacity; helical blade; feeding and discharging; silo systems
