Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0030] See also Figure 1-4 The utility model provides a device for measuring the release rate of nutrients in fertilizers, comprising: a box body 101, a fixed clamping plate 113 is fixedly connected to the bottom of the outer surface of the box body 101, a filter plate 112 is movably connected to the outer surface of the fixed clamping plate 113, a square plate 114 is fixedly connected to the bottom of the outer surface of the box body 101, and two L-shaped plates 116 are fixedly connected to the outer surface of the square plate 114. A pull rod 118 is movably embedded in the interior of the two L-shaped plates 116, and one end of the two pull rods 118 is fixedly connected to the limit plate 11 9. The two limit plates 119 are movably connected to the outer surfaces of the two square plates 114. The outer surfaces of the two limit plates 119 away from the square plates 114 are fixedly connected to springs 117. One ends of the two springs 117 are fixedly connected to the outer surfaces of the two L-shaped plates 116. The one-way valve 111 is rotated to release the potassium hydroxide mixed solution inside the box 101, and then enters the upper surface of the filter plate 112. After passing through the filter plate 112, the internal sediment and larger sand and gravel will be filtered to the upper surface of the filter plate 112.

[0031] like Figure 1-4 As shown, the outer surfaces of the two limit plates 119 away from the two springs 117 are fixedly connected with a clamping rod 120, and the outer surface of the filter plate 112 is provided with two clamping holes 115. Pulling the pull rod 118 drives the limit plate 119 and the clamping rod 120 to move to one side. After movement, the clamping rod 120 disengages from the inside of the clamping hole 115.

[0032] like Figure 1-4 As shown, the two clamping rods 120 are movably embedded in the two clamping holes 115. A detection box 106 is provided directly below the box body 101. The potassium hydroxide mixed solution enters the interior of the detection box 106. The interior of the detection box 106 is filled with a colored phenolphthalein solution. At this time, the phenolphthalein solution is dissolved in the potassium hydroxide mixed solution and reacts with the potassium hydroxide in the potassium hydroxide mixed solution, causing the mixed solution to change color. By observing the depth of the color change, the concentration of potassium hydroxide in the mixed solution can be determined.

[0033] like Figure 1-4 As shown, the outer surface of the detection box 106 near its bottom is fixedly connected to a water outlet pipe 107, and a one-way valve 108 is provided inside the water outlet pipe 107. The bottom of the inner wall of the box body 101 is fixedly connected to the porous barrel 102 through multiple support columns. The waste is poured into the cotton pad 103 in the porous barrel 102, and then the water liquid is poured into the cotton pad 103. The water in the washing liquid is mixed with the potassium oxide in the fertilizer to form a potassium hydroxide mixed solution.

[0034] like Figure 1-4 As shown, the gap between the porous barrel 102 and the bottom of the inner wall of the box body 101 is 10CM, and a cotton pad 103 is fixedly connected to the inner wall of the porous barrel 102 to prevent fertilizer from leaking from the small holes on the outer surface of the porous barrel 102.

[0035] like Figure 1-4 As shown, the bottom of the cotton pad 103 is movably connected to the chassis 105, and the top of the outer surface of the chassis 105 is fixedly connected to the long rod 104. When the fertilizer inside the box 101 is detected, the chassis 105 is set to prevent the fertilizer from staying at the bottom of the inner wall of the box 101 and being difficult to clean. The fertilizer inside can be drawn out by pulling the long rod 104.

[0036] like Figure 1-4 As shown, a thick tube 110 is fixedly connected to the bottom of the outer surface of the box body 101, and a one-way valve 111 is provided inside the thick tube 110. A water outlet 109 is provided at the bottom of the inner wall of the box body 101. The one-way valve 111 is rotated to release the liquid inside the box body 101 to prevent the liquid inside the box body 101 from being easily released.

[0037] Working principle: When in use, pour the waste into the cotton pad 103 in the porous barrel 102, and then pour the water liquid into the cotton pad 103. The water in the eluent is mixed with the potassium oxide in the fertilizer to form a potassium hydroxide mixed solution. The potassium hydroxide mixed solution penetrates to the outside through the small holes on the outer surface of the porous barrel 102 and is filtered through the cotton pad 103. The potassium hydroxide mixed solution enters the water outlet 109 and then reaches the inside of the thick pipe 110. Turn the one-way valve 111 to drain the potassium hydroxide mixed solution inside the box 101. The potassium hydroxide mixed solution enters the detection box 106, and the detection box 106 is filled with a phenolphthalein solution. At this time, the phenolphthalein solution dissolves in the potassium hydroxide mixed solution and reacts with the potassium hydroxide in the potassium hydroxide mixed solution to change the color of the mixed solution. By observing the depth of the color change, the potassium hydroxide concentration in the mixed solution can be judged, thereby reflecting the nutrient release rate of the fertilizer. When there is a lot of sediment and sand and gravel on the upper surface of the filter plate 112, the limit plate 119 and the clamping rod 120 are moved to one side by pulling the pull rod 118. After the movement, the clamping rod 120 is disengaged from the inside of the clamping hole 115. At this time, the filter plate 112 can be removed from the middle of the square plate 114 and the fixed clamping plate 113, and the sand and gravel sediment on its surface can be processed. Under the limiting action of the spring 117, the clamping rod 120 is clamped in the inside of the clamping hole 115 to fix the filter plate 112, and the installation and disassembly of the filter plate 112 is relatively simple.
