Description

一种制样粉碎机 【技术领域】
本发明主要涉及到制样设备领域，特指一种制样粉碎机。
【背景技术】
在现有技术的众多技术领域中，均需要进行物料样本的制作。例如，在煤样的测试领域，在对煤样进行多种试验分析之前，就需要制作具有代表性的煤料样本。在制作过程中，往往需要对煤样进行先行破碎，然后再收集，期间不能够有样本的损失，不能够令样本发生一些物理或化学变化，否则将会对最终的试验结果造成影响。
在制样过程中，常被使用到的是制样粉碎机，它是利用破碎刀具对从入料斗送入的物料进行破碎作业，然后再将破碎后的物料直接导入到一个瓶内进行收集。在这个过程中，往往会存在以下问题：破碎过程中会产生大量的粉尘或细微颗粒，容易残留和粘附在破碎刀具、破碎腔内壁上，造成样本的损失，也不利于拆卸和清洗。
【发明内容】
本发明要解决的技术问题就在于：针对现有技术存在的技术问题，本发明提供一种结构简单紧凑、能够进一步提高制样粉碎可靠性和精度的制样粉碎机。
为解决上述技术问题，本发明采用以下技术方案：
一种制样粉碎机，包括机架、控制组件及制粉组件，所述制粉组件包括入料斗、粉碎刀机构、收集盒和驱动件，所述入料斗位于粉碎刀机构的上方，所述粉碎刀机构包括粉碎腔和安装于粉碎腔内的粉碎刀，所述粉碎刀与驱动件的输出端相连，所述粉碎腔与收集盒连通，还包括一个以上的吹式清扫组件，所述吹式清扫组件包括气源和喷嘴，所述喷嘴的入口端与气源相连通，所述喷嘴的出口端朝向粉碎腔。
作为本发明的进一步改进：所述入料斗的出口位置处安装有入料控制阀，所述入料控制阀与控制组件相连。
作为本发明的进一步改进：所述收集盒的出口位置处安装有出料控制阀，所述出料控制阀与控制组件相连。
作为本发明的进一步改进：所述收集盒为具有一定高度的腔体。
作为本发明的进一步改进：所述收集盒上设置一个以上的震动下料部件。
作为本发明的进一步改进：所述收集盒与粉碎腔的接口处设置下料导流板。
作为本发明的进一步改进：所述收集盒与粉碎腔的接口处设置筛网。
作为本发明的进一步改进：所述收集盒的底部设有集料瓶。
作为本发明的进一步改进：所述收集盒呈环形布置于粉碎腔的周围并与粉碎腔连通。
作为本发明的进一步改进：所述收集盒与粉碎腔的接口处设置筛网。
作为本发明的进一步改进：所述粉碎刀为多个并呈一圈以上的排列，当为两圈以上时位于中心处的为粗碎刀，靠近粉碎腔内壁的为细碎执行件。
作为本发明的进一步改进：所述粉碎刀连接于一转盘上，所述转盘与驱动件的输出端相连。
与现有技术相比，本发明的优点在于：
1、本发明的煤经过粉碎执行件的粉碎后通过筛网完成过滤，直接进入收集盒，然后在重力的作用下自沉降，进而实现自动制样粉碎和收集煤粉过程。整个过程中煤粉是通过接料部件收集，不需要拆卸粉碎腔。在旋流的作用下，筛网上也不会有煤粉残留，不需要清理筛网，且粉碎过程中不会发生漏粉，煤粉收集效率非常高。
2、本发明利用吹式清扫组件在制粉工作结束后，将残留煤粉吹落到收集腔内，提高煤粉收集效率，同时有效防止研磨刀具托盘拐角处留有的少量煤粉残留。
3、本发明入料斗和收集盒的出口位置设置控制阀，利用控制阀可以有效控制入料、出料的速度和重量，进而优化整个破碎作业。
【附图说明】
图1是本发明在具体应用时的主视结构原理示意图。
图2是本发明中粉碎刀机构的结构原理示意图。
图例说明：
1、机架；2、控制组件；3、入料斗；4、粉碎刀机构；5、收集盒；6、集料瓶；7、驱动件；8、出料控制阀；9、震动下料部件；10、下料导流板；11、筛网；12、支承板；13、密封部；14、喷嘴；15、入料控制阀。
【具体实施方式】
以下将结合说明书附图和具体实施例对本发明做进一步详细说明。
如图1和图2所示，本发明的制样粉碎机，包括机架1、控制组件2及制粉组件，制粉组件包括入料斗3、粉碎刀机构4、收集盒5、集料瓶6和驱动件7，入料斗3位于粉碎刀机构4的上方，粉碎刀机构4包括粉碎腔和安装于粉碎腔内的粉碎刀，粉碎刀与驱动件7的输出端相连并在驱动件7的驱动下高速转动，对从入料斗3送入的物料(如：煤样)进行破碎，驱动件7可以根据实际需要采用电机或其他驱动件。破碎完的物料送入收集盒5，利用收集盒5的收集和导向将物料送入位于收集盒5底部的集料瓶6中，完成物料的收集。
本发明还包括一个以上的吹式清扫组件，吹式清扫组件包括气源和喷嘴14，喷嘴14的入口端与气源相连通，喷嘴14的出口端朝向粉碎腔。利用吹式清扫组件在制粉工作结束后，将残留煤粉吹落到收集腔内，提高煤粉收集效率，同时有效防止研磨刀具托盘拐角处留有的少量煤粉残留。同时，还可以采用多个吹式清扫组件，喷嘴14朝向不同的方式，对不同方向进行交替式或同时的吹扫，进而起到优化清扫效果的作用。
本实施例中，收集盒5为具有一定高度的腔体，利用煤粉的自重沉降进行落样。同时，进一步在收集盒5上设置震动下料部件9，利用震动下料部件9产生的震动，令粘附在收集盒5内壁上的煤料全部下落，进入集料瓶6，从而提高制样的精度。
本实施例中，在收集盒5与粉碎腔的接口处设置下料导流板10，以便完成破碎后的煤样可以快速、全部进入到收集盒5的腔体中去。
本实施例中，进一步在收集盒5与粉碎腔的接口处设置筛网11，利用筛网11对进入收集盒5的煤样进行一次过滤筛选。
本实施例中，收集盒5的腔体顶部与入料斗3的支承板12之间设置密封部13，收集盒5与粉碎腔的接口处设置于腔体的侧面，进而大大提高了收集盒5的密封性。
本实施例中，入料斗3的出口位置处安装有入料控制阀15，入料控制阀15与控制组件2相连。收集盒5的出口位置处安装有出料控制阀8，出料控制阀8与控制组件2相连。这样可以通过入料控制阀15和出料控制阀8对整个制粉过程进行控制。
如图2所示，本实施例中，粉碎腔为圆筒形，筒体的一部分或全部侧壁为筛网结构，供物料通过。若干个粉碎刀呈一圈以上的排列并连接于一转盘上，该转盘与驱动件7的输出端相连。当为两圈以上时，位于中心处的为粗碎刀，靠近粉碎腔内壁的为细碎刀。在物料下落到粉碎腔中时，粗碎刀会先对其形成破碎力，然后细碎刀会对甩起来的物料进行细碎，同时各个碎刀之间还能形成剪切力，对物料进行分割、破碎。
以上仅是本发明的优选实施方式，本发明的保护范围并不仅局限于上述实施例，凡属于本发明思路下的技术方案均属于本发明的保护范围。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理前提下的若干改进和润饰，应视为本发明的保护范围。
