Referring to Figures 1-3, a biochar application soil leaching sample collection device includes an upper plate 1 and a lower plate 2 arranged in parallel up and down, and two vertical slide rails are symmetrically and fixedly connected to the opposite sides of the upper plate 1 and the lower plate 2. 3, the vertical slide rail 3 is connected with the slide plate 6, and the sliding connection of the slide plate 6 and the vertical slide rail 3, and then the movement of the sampling cylinder 5 is limited, and the opposite sides of the two slide plates 6 are fixedly connected with the lower side opening. In the sampling cylinder 5 , a sampling port 4 is opened in the middle of the lower plate 2 , and the inner diameter of the sampling port 4 is larger than the outer diameter of the sampling cylinder 5 .

A multi-stage electric push rod 9 is fixedly installed through the middle of the upper end of the upper plate 1, which is the prior art. The telescopic end of the multi-stage electric push rod 9 is fixedly connected with a fixed rod 10, and the lower end of the fixed rod 10 is rotatably connected to a limit plate 11. , the outer side of the fixing rod 10 is provided with a positioning mechanism, the inner wall of the upper end of the sampling cylinder 5 is vertically sealed and slidingly connected with a sample plate 13, and the upper end of the sampling cylinder 5 is provided with a first socket 12 for the limit plate 11 to pass through. The upper end of 13 is provided with a second socket 14 into which the limiting plate 11 extends, and the shape and size of the first socket 12 and the second socket 14 are the same. The inner diameter of the limiting cavity 15 is equal to the width of the second socket 14, the width of the limiting plate 11 is smaller than the width of the first socket 12, and the limiting plate 11 is limited by size limitation.

It should be noted that the length of any side of the limit plate 11 is larger than the cross-sectional diameter of the multi-stage electric push rod 9, and the purpose of this setting is to prevent the limit plate 11 from passing through the first socket 12 or extending into the second socket 12. Socket 14 is blocked in the process.

A first spring 7 is movably sleeved on the outer wall of the vertical slide rail 3 , and the two ends of the first spring 7 are respectively abutted against the sliding plate 6 and the lower plate 2 , which facilitates the reset of the sampling cylinder 5 in the later stage.

The positioning mechanism includes a rotating cylinder 16 fixedly connected to the upper end of the limit plate 11, and the rotating cylinder 16 is sleeved on the outer side of the fixed rod 10. The outer wall of the fixed rod 10 is provided with four evenly distributed slots 8, and the inner wall of the rotating cylinder 16 and At the corresponding position of the slot 8 , the connecting plug 18 is fixed symmetrically by the second spring 17 .

It should be noted that two of the four slots 8 are in a parallel relationship with the limiting plate 11 , and the other two are in a three-dimensional vertical relationship. Gradually disengage, the second spring 17 is in a compressed state, and continues to rotate, the insert block 18 will be re-inserted into the slot 8 under the elastic force of the second spring 17, and the 90° rotation of the limit plate 11 is realized.
