[0020] To make the objectives and technical solutions of the embodiments of the present utility model clearer, the technical solutions of the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings of the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0021] As Figure 1As shown in the figure, the present utility model provides a sample preparation device, which includes a bottom plate 1, columns 2, a mold 3, side plates 4, screws 5 and nuts 6. The two ends of the bottom plate 1 are fixedly connected to the columns 2. The mold 3 is sleeved on the columns 2 and locked by the screws 5. The side plates 4 are sleeved on both sides of the mold 3 and locked by the nuts 6. The bottom plate 1 is a square plate, and the two ends of the bottom plate 1 are fixedly connected to the columns 2 for installing the mold 3. The columns 2 are cylindrical, and threaded blind holes matching the diameter of the screws 5 are opened at the top ends of the columns 2 to cooperate with the screws 5 to fix the mold 3 and prevent the mold 3 from sliding when filling samples. The mold 3 includes through holes 31, grooves 32 and studs 33. The through holes 31 are located at both ends of the mold 3. A triangular pyramid-shaped groove 32 is opened at the center of the surface of the mold 3. At least two studs 33 are provided on both sides of the mold 3. The mold 3 is a cuboid. The through holes 31 opened in the mold 3 correspond to the diameter dimensions of the columns 2 so that the columns 2 can pass through for installation. The triangular pyramid-shaped groove 32 of the mold 3 is used for filling sample powder to form a uniform reactor. The depth of the groove 32 is a1, and the length of the mold 3 is b1. In order to further limit the mold 3, L-shaped side plates 4 are installed on both sides of the mold 3. Round holes 41 are opened on the side plates 4 for the studs 33 to pass through, and the nuts 6 are tightened on the studs 33 to produce multi-position fitting of the side plates 4 with the mold 3 and the base 1, realizing effective limitation of the mold 3.
[0022] As Figure 2 shown in the figure, the present utility model provides a combustion cover plate. The cover plate 7 includes a sample groove 71 and scales 72. The sample groove 71 is located on the central surface of the cover plate 7, and the scales 72 are arranged on both sides of the sample groove 71. The sample groove 71 is used for containing a pesticide sample pile 8 and carrying out a combustion reaction. The sample groove 71 can be used to limit the sample powder to prevent sample splashing generated by heat flow during the combustion process or limit the combustion extension. The length of the sample groove 71 is a2, and the length of the sample pile 8 is b2. The size of the sample groove 71 matches the size of the mold 3 (see Figure 1 ), that is, a1 = a2, b1 = b2. The scales 72 are evenly distributed on both sides of the sample groove 71 for easy direct reading.
[0023] As Figure 3 shown in the figure, it is the usage method of the sample preparation device. After the pesticide sample in the groove 32 (see Figure 1 ) is evenly filled and compacted, the screws 5 (see Figure 1 ) and the nuts 6 (see Figure 1 ) will be unscrewed in sequence, and the side plates 4 (see Figure 1), and take out the mold 3. Invert the cover plate 7 on the mold so that the sample grooves 71 (see Figure 2 ) on the mold 3 and the cover plate 7 are fitted together. Hold the mold 3 and the cover plate 7 tightly with both hands and turn them over as a whole. Remove the mold 3 to complete the production of the sample stack 8 (see Figure 2 ) on the cover plate 7.
[0024] As Figure 4 shown, the device 9 includes a protective cover 91 and a baffle 92, and the baffle 92 is installed at the front end of the protective cover 91. The protective cover 91 is a rectangular parallelepiped metal shell, the bottom of the protective cover 91 is hollowed out, the bottom end of the protective cover 91 is turned inward, and a handle is installed at the top of the protective cover 91. The baffle 92 is made of glass, which is convenient for observing the combustion reaction and reading. Place the cover plate 7 with the uniform sample stack 8 in the protective cover 91, use a lighter to ignite the sample, and fasten the baffle 92 to directly read the burning length of the sample. At the same time, record the stopwatch time to calculate the burning rate of the sample.
[0025] In summary, the present invention provides a sample preparation device. By designing the mold 3 with a triangular pyramid-shaped groove 32 and the cover plate 7 with a scale 72, a uniform reactor is prepared by an inverted method. In addition, by externally arranging the protective cover 91 and the baffle 92, the safety and intuitiveness of the combustion performance test are realized.
[0026] Although the present invention has been disclosed as above with embodiments, it is not intended to limit the present invention. Any person with ordinary knowledge in the technical field to which the present invention pertains can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to that defined by the appended patent application scope.
