[0009] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0010] Example 1

[0011] like Figure 1 As shown, embodiment 1 of the present invention provides a plant nutrient component measuring device, including a measuring instrument and a grinder, wherein the grinder includes a fixed seat 4, a grinding mortar 2 with a plurality of grinding grooves, and a plurality of grinding pestles 3 corresponding to the grinding grooves one by one, each of the grinding pestles 3 is provided with a first drainage flow hole 31, the first drainage flow hole 31 extends from the grinding end of the grinding pestle 3 to the non-grinding end, the end of the first drainage flow hole 31 close to the grinding end is movably blocked by a first drainage plug 32, the end of the first drainage flow hole 31 close to the non-grinding end is connected to the measuring instrument through a drainage tube 1, the non-grinding ends of the grinding pestles 3 are connected to the fixed seat 4, and the fixed seat 4 is connected to the grinding mortar 2 through an electric push rod 5.

[0012] In the embodiment of the present invention, the grinder is used to grind plants to obtain grinding liquid, and the measuring instrument is used to measure the nutrient content in the grinding liquid. In this embodiment, a first drainage hole 31 is set in the grinding pestle 3, and the first drainage hole 31 is plugged by the first drainage plug 32 during grinding. The electric push rod 5 drives each grinding pestle 3 to move up and down together through the fixed seat 4, thereby realizing the pounding and grinding of the plant. After the grinding is completed, organic solvent extraction or other processing steps are performed according to the plant category and the specific measurement items. After the processing is completed, the first drainage plug 32 is pulled out, and the drainage of the processed grinding liquid is realized through the grinding pestle 3 and the drainage tube 1, and it is drained to the detection instrument for detection, thereby realizing the automation of the detection process and improving the grinding and detection efficiency.

[0013] The drainage tube 1 can be realized by a siphon tube, so that the automatic drainage of the grinding liquid can be realized through the siphon phenomenon. A peristaltic pump or a titration pump can also be installed on the drainage tube 1 to realize the drainage of the grinding liquid.

[0014] The plant nutrient component measuring device provided by the embodiment of the present invention has the technical effect of high grinding and detection efficiency.

[0015] Preferably, the grinding grooves are distributed in a circle, and the electric push rod 5 is arranged at the center of the circle.

[0016] The grinding grooves are distributed in a circle, so that each grinding pestle 3 is also distributed in a circle during grinding. The electric push rod 5 applies a thrust to the fixed seat 4 at the center of the circle formed by each grinding pestle 3, so that each grinding pestle 3 can grind at the same time, and the force on each grinding pestle 3 is uniform and stable.

[0017] Preferably, the measuring instrument is a spectrometer or a chromatograph.

[0018] Spectrometers and chromatographs analyze plant nutrients such as nitrogen, potassium, and phosphorus through spectral analysis and chromatographic analysis.

[0019] Preferably, the grinding end and the non-grinding end of the grinding pestle 3 are detachably connected.

[0020] The grinding end and the non-grinding end are detachably connected, so as to facilitate the cleaning of the first drainage hole 31 inside the grinding pestle 3.

[0021] Preferably, Figure 1 As shown, the grinding mortar 2 is provided with a second drainage hole 21 connected with the grinding groove, and the second drainage hole 21 is movably blocked by a second drainage plug 22 .

[0022] Some grinding liquids or extracts are not easy to transmit through the drainage tube 1, so a second drainage hole 21 is set to provide a second way to transmit the grinding liquid extract. First, the first drainage hole is plugged by the first drainage plug 32, and the second drainage hole is plugged by the second drainage plug 22. After grinding through the grinding end, the first drainage hole or the second drainage hole is opened to realize the drainage of the grinding liquid. Similarly, when draining through the second drainage hole, a siphon or a peristaltic pump or a titration pump can also be used to realize the drainage and transmission of the grinding liquid. The apertures of the first drainage hole and the second drainage hole are preferably set to different sizes to meet different drainage requirements. At the same time, the first drainage hole and the second drainage hole are preferably detachably connected to the filter screen to meet the filtering requirements of some grinding liquids or extracts.

[0023] Preferably, Figure 1 As shown, the grinding grooves are of different sizes.

[0024] Grinding grooves of different sizes are suitable for grinding different plants and different plant parts.

[0025] Preferably, Figure 1 As shown, the grinding pestle 3 is provided with a limiting plate 33 matching the depth of the corresponding grinding groove.

[0026] A limit plate 33 is provided on the grinding pestle 3 to limit the upper and lower pounding pestles during grinding. An elastic buffer, such as a rubber pad, a spring, etc., is preferably provided on the side of the limit plate 33 facing the grinding mortar 2 to achieve buffering during grinding and avoid excessive wear on the grinding mortar 2 and the grinding pestle 3.

[0027] Preferably, Figure 1 As shown, the grinding surface of the grinding end is a curved surface or a flat surface.

[0028] The curved and flat grinding surfaces each have their own advantages and disadvantages. The curved surface is suitable for grinding the roots, stems, leaves and other parts of the plant that are not too hard and not easy to roll, while the flat surface is suitable for grinding the seeds and other parts of the plant that are relatively hard and easy to roll. The grinding end of each grinding pestle 3 is set to a different grinding surface, so that the plant nutrient component measuring device provided by the present invention can be used for grinding detection of different parts of different plants at the same time. A plurality of grinding ends with different grinding surfaces are also set for each grinding pestle 3, and the grinding end is detachably connected to the non-grinding end, so that the corresponding grinding end can be selected for use during grinding, providing a more free and convenient choice.

[0029] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
