注意称为的节点(fill)，它们用于确保质量表面m是一个连续的表面（手推车……）然而，放大后，我看到线条之间不连续。我该如何解决这个问题？

角框北侧和东侧的白色空间是由于节点默认具有非零值inner sep。outer sep可以进行的其他更改是相对于其他节点定位节点以及使用节点锚点。
只需添加inner sep=0pt,outer sep=0pt即可\tikzstyle{ground}{...}解决角落方块的问题。

为了响应 OP 更新的代码，我做了一些更改，主要是沿路径定义节点，以便更自动地放置它们。例如
\draw [-latex,ultra thick] (M.north east) ++ (0cm, 0.5cm) -- +(1cm,0cm);
\node (y1) at (M.north east) [xshift = 1.2cm, yshift = 0.5cm] {$y_1$};
可以替换为
\draw [-latex,ultra thick] (M.north east) ++(0cm, 0.5cm) -- +(1cm,0cm) node [right] (y1) {$y_1$};
它将y1节点放置在刚刚绘制的箭头的末端，在我看来，这已经将标签$y_1$置于自然位置，对我来说，这比定义节点相对于箭头起点的位置更有意义。当然，仍然可以使用xshift和yshift进行精细定位，但现在这些移位只需要进行小得多的调整（正如我下面所做的定位节点b）。

答案2
新答案
正如 Hans-Peter E. Kristiansen 指出的那样，我最初的假设（原始答案）patterns是错误的，尽管它不会使解决方案无效。
无论如何，我一直在努力解决看似 OP 的问题：How to draw a filled wall+ground corner with a certain width。
我之前的回答和戴博文的回答都是以未绘制的节点为基础的，后来这些节点被用作绘制图案角的参考。
在这种情况下，我展示了另一种方法。
首先，绘制带有（或不带有）所有所需标签的机械系统：
现在我们想绘制一个足够大的地面角来容纳系统。但可能我们不知道或不想计算系统尺寸。没问题，TikZ可以帮助我们，因为在每个绘图命令之后，它都会计算一个current bounging box足够大的节点来包含到目前为止所绘制的内容。这就是下图中虚线红色矩形所示的内容：
并且这个current bounding box节点的角可以作为参考来绘制所需的墙面和地面。
作为示例，\drawwall已定义命令来简化此任务。它使用三个参数，第一个是current bounding box.north与墙最顶部线之间的垂直距离，第二个是current bounding box.east与地面最右端之间的距离，第三个是墙/地面宽度。
%#1 - vertical oversize
%#2 - horizontal oversize
%#3 - wall width
\newcommand{\drawwall}[3]{%
\draw[ground]%
(current bounding box.south west)|-
([shift={(-#3,#1)}]current bounding box.north west)|-
([shift={(#2,-#3)}]current bounding box.south east)|-
cycle;
}
通过这个命令很容易获得：
或者
无需担心系统尺寸、规模……

原始答案
我认为每个patterns都有自己的起源，因此它们在每个节点内都是独立绘制的。
因此，如果您想获得连续的图案，您应该将填充区域声明为一个整体。
我在下面的代码中所做的就是保留你的ground和wall节点作为参考，但不绘制或填充任何图案。一旦它们存在，它们就可以用来声明整个区域：
\draw[pattern=north east lines ] (wall.south west)|-(ground.south east)|-(wall.north east)|- cycle;
为了理解上一行，您应该记住wall节点已旋转（rotate=-90），因此其左上角是south west而不是north west，而右下角是north east。
有了先前的声明，fill节点就不再需要了。
我还将tikzstyle弃用的声明更改为tikzstyle。
