具体实施方式
以下由特定的具体实施例说明本发明的实施方式，熟悉此技术的人士可由本说明书所揭露的内容轻易地了解本发明的其他优点及功效。
如图1所示，一种土壤污染监测装置，包括装置本体1，所述装置本体1包括重金属传感器22、酸碱传感器23和显示屏28，所述装置本体1左右两侧的内部分别设有左内腔3和右内腔4，所述左内腔3内部底端左侧固定有第一底缸5，所述第一底缸5内部滑动连接有第一活塞6，所述第一活塞6上端转动连接有丝杆12，所述第一底缸5上端开口外侧固定有螺帽11，所述丝杆12上端沿着所述第一底缸5延伸出所述螺帽11，所述丝杆12与所述螺帽11转动连接，所述左内腔3内部底端右侧固定有第二底缸7，所述第二底缸7内部下侧滑动连接有第二活塞8，所述第二活塞8上端相接有连杆9，所述连杆9上端相接有第三活塞10，所述第三活塞10与所述第二底缸7滑动连接，所述第二底缸7上端固定连接有呈L字型结构的连接管16，所述连接管16尾端贯穿过所述装置本体1，所述装置本体1上端中间固定有第三底缸17，所述第三底缸17内部上侧滑动连接有第四活塞18，所述第四活塞18下端相接有活塞杆19，所述装置本体1下端中间开有底槽2，所述活塞杆19下端贯穿到所述底槽2内部，所述活塞杆19下端相接有压板20，所述第一底缸5与所述第二底缸7之间的下侧相接有连管，所述第一底缸5和所述第二底缸7均与所述连管相通，所述连接管16头端贯穿到所述第二底缸7内部与所述第二底缸7相通，所述连接管16尾端贯穿到所述第三底缸17内部与所述第三底缸17相通，所述第一底缸5、所述第二底缸7、所述连接管16和所述第三底缸17内部均布置有液压油，首先，将装置本体1放在地上，通过顺时针转动丝杆12，随着丝杆12与螺帽11顺时针转动而往下拧入，而将第一活塞6推动着在第一底缸5内往下移动，随着第一活塞6往下移动将液压油沿着连管推入第二底缸7，而使第二活塞8被液压油推动往上移动，进而利用连杆9带动第三活塞10往上推动液压油，随着第三活塞10将液压油利用连接管16推入第三底缸17内，而使第四活塞18被液压油推动着往下移动，从而可以利用活塞杆19将压板20推着带动锥杆21往下插入土壤内部。
另外，当逆时针转动丝杆12时，随着丝杆12与螺帽11逆时针转动而往上拧出，而将第一活塞6拉着在第一底缸5内往上移动，随着第一活塞6往上移动抽动着液压油在第一底缸5内液面上升，而使第二活塞8下液压油液面降低，进而使第三活塞10往下移动将第三底缸17内的液压油抽入第二底缸7内，使第四活塞18随着液压油被抽出第三底缸17而往上移动，从而可以利用活塞杆19将压板20拉着带动锥杆21往上拔出土壤，这样不仅更加 省力，而且更加方便。
如图1至图2所示，根据上述实施例所述，进一步的，所述装置本体1左右两端上侧均固定安装有轴承29，每个所述轴承29远离所述装置本体1的一端均转动连接有呈L字型结构的锁杆24，所述装置本体1左右两端下侧均铰接有踩板14，所述踩板14右端开有凹槽15，所述踩板14与所述锁杆24相贴，在转动丝杆12的时候，由于踩板14平时垂直着被锁杆24挡着与装置本体1相贴，使得通过轴承29转动锁杆24到不再挡住踩板14，这时踩板14活动展开至呈水平状，这样用脚踩在踩板14上的凹槽15内，可以避免出现因为转动丝杆12而使装置本体1移位的现象。
如图1至图3所示，根据上述实施例所述，本实施例与上述实施例不同的是，所述右内腔4内部转动连接有转轴25，所述转轴25外部固定有卷线筒26，所述转轴25外部贯穿设置有空心圆板27，所述空心圆板27位于所述卷线筒26左方与所述右内腔4固定连接，所述空心圆板27内部设有螺旋弹簧片30，所述螺旋弹簧片30头尾两端分别与所述转轴25和所述空心圆板27焊接，当锥杆21往下移动插入土壤内时，随着重金属传感器22和酸碱传感器23也插入土壤，可以拉动着信号线从卷线筒26外壁解下，而使卷线筒26通过转轴25顺时针转动。
当转轴25顺时针转动时，可以拉动螺旋弹簧片30的头端卷在转轴25外壁，反之，当锥杆21往上移动拔出土壤内时，随着螺旋弹簧片30因为弹力而复位，可以带动转轴25逆时针转动，随着转轴25带动卷线筒26逆时针转动而将信号线重新缠在卷线筒26外壁，从而不会因为信号线长短的问题而影响重金属传感器22和酸碱传感器23进入土壤。
如图1所示，作为优选的，所述丝杆12上端贯穿过所述装置本体1，所述丝杆12上端通过电焊焊接有手轮13，在需要转动丝杆12的时候，通过握住手轮13，可以更加省力的转动丝杆12。
如图1所示，具体的，所述压板20下端左右两侧均通过电焊焊接有锥杆21，所述重金属传感器22固定安装在右侧的所述锥杆21右端，所述酸碱传感器23固定安装在左侧的所述锥杆21左端，所述显示屏28安装在所述装置本体1上端右侧，所述重金属传感器22和所述酸碱传感器23均通过信号线与所述显示屏28连接，当锥杆21被压板20带动往下移动的时候，随着左右两根锥杆21插入土壤内，而使重金属传感器22和酸碱传感器23同时插入土壤内，使得通过重金属传感器22和酸碱传感器23读取土壤中的重金属含量和酸碱度，之后再通过信号线将土壤中的重金属和酸碱度的数据传输至显示屏28显示出来。
以上显示和描述了本发明的基本原理和主要特征和本发明的优点。本行业的技术人员应该了解，本发明不受上述实施例的限制，上述实施例和说明书中描述的只是说明本发明的原 理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
