    [0038]具体实施方式
    [0039]为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对实施例中的技术方案进行清楚、完整地描述,以下实施例用于说明本发明,但不用来限制本发明的范围。
    [0040]实施例1:参照图1、图2、图3、图5、图7,一种园林废弃物处理用粉碎装置,包括罐体1,罐体1上转动连接有罐盖101,如图1、图2所示,罐体1上设置有电机,电机用于罐盖101的转动,还包括:两组转动板103,转动连接在罐体1内,转动板103用于将罐体1分割成上下两层;多组排液口1031,均设置在转动板103上,排液口1031内设置有电子阀;多组伸缩杆301,固定连接在罐盖101上,伸缩杆301的输出端上固定连接有多组插杆302,插杆302用于抵在转动板103上;多组喷液口1021,呈圆周状设置在罐体1内,喷液口1021用于将罐体1内的水保持旋涡状流动;水泵7,连接在罐体1底部,水泵7上连接有管路一701、管路二702、管路三703,管路一701和管路三703用于将罐体1内的水排出罐体1,管路二702用于向喷液口1021补水,管路一701、管路三703内均设置有滤网,罐体1内固定连接有固定板104,固定板104上转动连接有伸缩缸105,伸缩缸105的伸缩端与转动板103转动连接,罐体1内设置有粉碎室2,粉碎室2内转动连接有多组粉碎辊201,粉碎辊201用于粉碎转动板103上落下的塑料瓶或者木头,还包括两组储存罐5,储存罐5上连接有连接软管501,储存罐5用于储存粉碎室2内粉碎的塑料瓶或者木头。
    [0041]本装置在使用的时候,需要将本装置安装在园林的湖面内,此时本装置罐体1的罐口略低于水面,由于湖面可能会有一些漂浮的废弃物,如塑料瓶、树枝等,此时便可启动水泵7(此刻转动板103中排液口1031的电子阀处于打开状态,此时水将充盈整个罐体1),通过管路一701、管路三703的配合(管路一701、管路三703是进液还是出液,受到水泵7的控制,当管路一701出液,则管路三703为出液,此时将罐体1内的水排出),将罐体1中的水排出,使其排到外界的湖水内,此时会产生一定的负压,进而将外界的水吸入,此时的水会将水面上的废弃物吸附,使其进入罐体1内,由于排液口1031打开但是转动板103仍处于阻挡状态,此时水能进入下方的粉碎室2内,最终通过管路一701、管路二702排出(部分较小的杂物将会被滤网遮挡,此时可启动粉碎辊201对其进行粉碎,随之直接排出罐体1),但是较大的将堆积在转动板103上,当罐体1内装有一定量的杂物的时候(一般占据转动板103至罐口空间一半的时候,可通过在罐体1内设置传感器,用于检测内部储存废弃物的量),便可通过电机使罐盖101进行转动,进而使罐盖101对罐体1的罐口进行遮挡,避免外界水以及废弃物的流入,此时排液口1031内的电子阀仍处于打开状态,故多余的水会继续进行流出,当水占据转动板103至罐口空间一半的时候,便可关上水泵7,此时可启动伸缩杆301,使收缩至罐盖101内的插杆302(插杆302平时位于伸缩杆301内,且完全收缩的情况下,自身的尖锐端位于罐盖101内,不伸出罐盖101,多组插杆302呈圆周状设置,且均匀分布,用于刺穿废弃物,使其表面形成插孔),此时插杆302的下移,将会插入下方的废弃物内(塑料瓶或者树枝),直至插杆302抵住下方的转动板103,后续插杆302复位,恢复到初始状态,此时由于插杆302收回罐盖101内,故一些粘连的废弃物将掉落至下方,此时便可反向启动水泵7,通过水泵7将外界的水吸入,进而使水通过管路二702进入喷液口1021内(此时水泵7反转,管路三703将进液,将外界的水吸入,管路三703上也可设置滤网,此时管路一701关闭,水将通过管路二702排出),此时剩余的水将呈螺旋状流动,进而促使废弃物进行翻转,由于先前刺穿了废弃物,尤其是一些塑料瓶,此时的翻转会使水快速的进入其中,同时内部的气体将快速排出(能漂浮在水面上的塑料瓶,一般是内部有气体),此时这些塑料瓶将快速沉底,而树枝将继续浮在水面上,以此实现分层(在分层的过程中,可通过伸缩杆301使插杆302再次下移,来到转动板103与罐口空间一半的位置,增加塑料瓶与水的接触时间,避免部分塑料瓶浮在水面无法与水充分接触,将内部的气体排除,或者直接刺到底部,增加塑料瓶上插孔的数量,增加水进入塑料瓶内的可能,也可两种方式相互配合使用,当水多的时候,便可打开转动板103上的排液口1031排出),此时便可使伸缩缸105收缩,使沉底的塑料瓶从转动板103与罐体1内壁之间的缝隙排出(此过程要重复多次,因塑料瓶会随着水一起流入,部分塑料瓶会由于位于中心,在转动板103反转的时候,会随着液体流动而移动,但不会一次性全部来到下方的粉碎室2,需要重复多次,此时要持续向罐体1内补充水,进而便于有效地分离),在分离完成后,此时粉碎室内是塑料瓶,而转动板103上则是树枝。
    [0042]后续便可通过粉碎辊201,通过粉碎辊201对塑料瓶进行粉碎,最后打开其中一个连接软管501(连接软管501内部设置有电子阀),粉碎室2内部的水以及粉碎成碎片的塑料瓶一起进入其中一个储存罐5内(在粉碎完成后,可通过打开上方转动板103的电子阀,使部分水留下,进而对粉碎轴上可能残留的一些塑料片进行冲击,使其流到底部,便于完全的排出,同时粉碎室2内的大部分水需要通过水泵7进行排出至外界,避免大量的水流入影响储存罐5的储存量),在对塑料瓶完成粉碎后,便可再次使转动板103转动,使残留的树木来到下方的粉碎室,进行粉碎,后续排至另一组储存罐5内(两组储存罐5中一组是塑料碎片,而另一组不光包括树枝,一些浮水的杂物,如泡沫板、树叶等,本申请主要目的是将一些浮在水面上的塑料瓶从杂物中分离,便于回收再利用),完成分类储存,后续塑料片可进行回收处理,而树枝碎片可直接进行掩埋,或者焚烧,起到堆肥的作用。
    [0043]本申请中管路三703还有一种实施方式,如图9所示,管路三703可额外设置多组,额外设置的呈环状设置,且进水端贴近水面,这样在进行后续排液口1031喷水的时候,便可通过这种网状的结构将周围较远的水面废弃物进行吸取(吸水产生的流动,会带动较远的废弃物的流动,使其靠近罐体1,便于对一些较远的废弃物进行处理),在排水的时候,可直接从初始的管路三703进行排出。
    [0044]实施例2:参照图2、图3、图6,一种园林废弃物处理用粉碎装置,与实施例1基本相同,更进一步的是:罐体1内固定连接有隔板102,隔板102用于防止水的流出,喷液口1021固定连接在隔板102上。
    [0045]如图2、图3、图6所示,隔板102呈圆环状设置,其中间区域设置有一个横板,圆环用于避免水通过转动板103与罐体1的内部排出,而中间的横板用于避免水通过两组转动板103之间的间隙排出,为确保密封,转动板103表面可设置为橡胶层,通过挤压形变增加密封性。
    [0046]实施例3:参照图5、图7,一种园林废弃物处理用粉碎装置,与实施例2基本相同,更进一步的是:粉碎室2上固定连接有驱动电机203,粉碎室2底部啮合连接有多组传动齿轮202,驱动电机203的输出端与其中一组传动齿轮202固定连接,传动齿轮202与粉碎辊201固定连接。
    [0047]通过驱动电机203和传动齿轮202的设置,可有效地使粉碎辊201进行同步的转动,对塑料瓶或者树枝进行粉碎。
    [0048]实施例4:参照图5、图7、图8,一种园林废弃物处理用粉碎装置,与实施例3基本相同,更进一步的是:罐体1内固定连接有气泵4,气泵4的出气端和进气端上分别连接有出气管401和进气管402,储存罐5上连接有充气气囊一502,充气气囊一502与出气管401连接,罐体1上连接有充气气囊二6,充气气囊二6上连接有出气副管403,出气副管403与充气气囊二6相通,进气管402远离气泵4的一端上连接有浮水球4021,出气管401、进气管402、出气副管403内均设置有电子阀。
    [0049]本装置在使用的时候,且确保罐体1能浮在水中,可通过气泵4,将外界气体吸入,进而使其进入充气气囊二6内,进而使罐体1能浮在水中(气泵4为双向泵,可将充气气囊二6中的气体吸走,通过进气管402排出,同时具体位置可在罐体1上设置传感器,便于确定罐体1的位置),其中充气气囊二6可不设置,但此时需要对罐体1位置进行固定,避免罐体1沉底,本实施例采用使用充气气囊二6的方式,便于在雨季或者旱季的使用。
    [0050]同时储存罐5平时可沉在水中,便于粉碎后的塑料片或者树枝通过连接软管501进入储存罐5内,同时避免部分水面废弃物堆积在储存罐5附近,形成悬浮物浮岛,影响对水面废弃物的回收处理,在后续工做人员需要进行回收的时候,便可打开气泵4,使气体进入充气气囊一502内,进而使原先沉在水中的储存罐5悬浮,来到水面上,便于工作人员将储存罐5打捞起来。
    [0051]本装置中的储存罐5还有一种实施方式,如图10所示,在储存罐5内部设置筛网503,此时储存罐5形成两个空间,筛网503下方的空间内设置加热丝504,并在充气气囊一502上设置连接管,连接管内设置电子阀,同时在储存罐5顶部设置排气口505,排气口505内设置单向出气阀,此时在使用的时候,粉碎后的塑料片或者树枝碎屑将会顺着水通过连接软管501进入储存罐5内,此时便可打开气泵4和加热丝504,气泵4会将外界气体吸入,进而进入充气气囊一502内,最终通过连接管进入储存罐5内,同时筛网503会将粉碎后的废弃物以及水进行分离,水将进入下方,同时加热丝504产生的热量将会使底部的水升温,最终产生水蒸气(此过程中筛网503上方的废弃物将会被同步加热,对可能携带的一些虫卵、病菌进行消杀),而水蒸气最终将通过排气口505排出,后续随着加热的进行,水将蒸发完毕(常规状态下会留有一定的水,便于储存罐5沉在水中,而不会漂浮在水面,在最后即将要进行打捞的时候,才进行蒸发),最后气体将直接与加热丝504接触,此时具有一定温度的气体将与废弃物接触,对废弃物进行烘干,而多余的气体将通过排气口505排出,排出的气体在一定程度上能增加水的水氧含量(在正常加热的时候,气体可增加液体流动速度,进而使水温整体持平,促进水的蒸发与沸腾,同时多余的气体也会排出),这样烘干完成后,能有效减少储存罐5中水的含量,减少重量的同时,在自身浮力的作用下,会浮在水面上,便于后续的打捞,充气气囊一502可保证在装有大量废弃物的情况下,能浮在水面。
    [0052]本发明通过插杆302与水的配合,能有效地将浮在水面上的塑料瓶进行沉底,对塑料瓶与树枝等浮水杂物进行分离,便于后续单独对塑料瓶和树枝的粉碎,便于进行回收再利用。
    [0053]以上所述仅是本发明的较佳实施例而已,并非对本发明作任何形式上的限制,虽然本发明已以较佳实施例揭露如上,然而并非用以限定本发明,任何熟悉本专利的技术人员在不脱离本发明技术方案范围内,当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例,但凡是未脱离本发明技术方案的内容,依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰,均仍属于本发明方案的范围内。
