Description

一种交叉斜置式宽度可调开沟机
技术领域
本发明涉及设施农业开沟作业机械，具体而言涉及一种交叉斜置式宽度可调开沟机。
背景技术
随着温室蔬菜种植面积不断扩大，反季节栽培发展迅速，极大地改变了土地原有的理化性质和生物学环境。主要表现在以下几个方面：1、土壤盐渍化；2、有机质含量下降，土壤板结；3、土壤微生物区系严重恶化，有益菌群急剧减少，疫病、根腐病等土传病害严重发生。而秸秆生物反应堆技术一方面可以解决农村大量剩余秸秆的综合利用问题，控制设施农业土壤病害的传播，减少农药用量，改善农产品品质，生产出有机、绿色农产品；另一方面也能使设施蔬菜土壤的理化性质和生物学性状得到改善，进而获得高产、优质、早熟的蔬菜产品，对我国的设施蔬菜生产具有重要的意义。
但秸秆生物反应堆技术中关键的开沟施工环节依然靠手工作业，劳动强度大，工作环境差，效率低且作业质量差，对秸秆生物反应堆技术的进一步推广已构成约束。
发明内容
本发明的目的是提供一种交叉斜置式宽度可调开沟机，该交叉式宽度可调开沟机可以实现开沟宽度自动调节且整机结构简单、性能可靠、稳定性较高。
为实现上述目的，本发明采取以下技术方案：
一种交叉斜置式宽度可调开沟机，包括悬挂机架，其特征在于：所述悬挂机架左右两侧对称布置有左开沟刀组件和右开沟刀组件，所述左开沟刀组件中的开沟刀片和右开沟刀组件的开沟刀片在轴线方向上交叉布置；所述左开沟刀组件的前后两端分别经左前摇臂和左后摇臂与悬挂机架铰接相连，所述右开沟刀组件分别经右前摇臂和右后摇臂与悬挂机架铰接相连；左开沟刀组件前端经连接法兰盘I与液压马达I相连，右开沟刀组件前端经连接法兰盘Ⅱ与液压马达Ⅱ相连；所述左开沟刀组件后端与右开沟刀组件的后端分别与双杆液压缸的两端铰接相连。
上述技术方案中，所述的悬挂机架设有三个铰接点可与拖拉机等农用机械相连，经液压管路将农用机械自身的液压油输送给液压马达I、液压马达Ⅱ和双杆液压缸。液压马达I、液压马达Ⅱ可以分别驱动左开沟刀组件和右开沟刀组件旋转，实现开沟抛土作业，双杆液压缸的伸缩可以调节该开沟机的开沟宽度，而且开沟作业的宽度是无级可调的。该交叉式宽度可调开沟机可以实现开沟宽度自动调节且整机结构简单、性能可靠、稳定性较高。

具体实施方式
下面结合附图，对本发明做进一步说明：
如图1、图2、图3和图4所示，一种交叉斜置式宽度可调开沟机，包括悬挂机架5、左开沟刀组件1、右开沟刀组件9、液压马达I4、液压马达Ⅱ6、双杆液压缸11、连接法兰盘I3、连接法兰盘Ⅱ7、左前摇臂2、左后摇臂12、右前摇臂8、右后摇臂10、弧形机罩13，所述悬挂机架5左右两侧对称布置有左开沟刀组件1和右开沟刀组件9，左开沟刀组件1的前后两端分别经左前摇臂2和左后摇臂12与悬挂机架5铰接相连，右开沟刀组件9的前后两端分别经右前摇臂8和右后摇臂10与悬挂机架5铰接相连；左开沟刀组件1和右开沟刀组件9均由刀轴、开沟刀片、螺栓组装而成；左开沟刀组件1前端与连接法兰盘I相连，连接法兰盘I经法兰螺栓与液压马达I相连，右开沟刀组件9前端与连接法兰盘Ⅱ相连，连接法兰盘Ⅱ经法兰螺栓与液压马达Ⅱ相连；所述左开沟刀组件1后端与右开沟刀组件9的后端分别与双杆液压缸11的两端铰接相连；左开沟刀组件1和右开沟刀组件9上侧分别设置有弧形机罩13。
所述左开沟刀组件1中的开沟刀片和右开沟刀组件9的开沟刀片在轴线方向上交叉布置，左开沟刀组件1和右开沟刀组件9沿作业方向成后端低前端高倾斜布置。
悬挂机架5设有三个铰接点可与动力机械相连，经液压管路将动力机械自身的液压油输送给液压马达I、液压马达Ⅱ和双杆液压缸11。液压马达I、液压马达Ⅱ可以分别驱动左开沟刀组件1和右开沟刀组件9旋转，实现开沟抛土作业，双杆液压缸11的伸缩可以调节该开沟机的开沟宽度。该交叉式宽度可调开沟机可以实现开沟宽度自动调节且整机结构简单、性能可靠、稳定性较高。
本实施例只是对本发明的构思和实现的一个说明，并非对其进行限制，在本发明构思下，未经实质变换的技术方案仍然在保护范围内。
