Detailed description of the invention
Embodiment one, as shown in Figure 1 to Figure 3, this sampler forms primarily of three parts:
1) the square blade fixed head 1 of 3cm × 3cm, fixed head can adopt plank, plastic plate or aluminium alloy plate to make, at the side opening blade installation slot of fixed head, and drill screw holes, for fixed blade.
2) 2 four, the rectangle blade of 3cm × 1cm, every a slice is fixed in the side blade installation slot of fixed head, and uses screw 21 fastening, and four blades form a coherent square cut instrument along fixed head surrounding.
3) the square backing plate 3 of 4cm × 4cm, is provided with the groove 31 of a 3cm × 3cm in the central authorities of backing plate, further, can lay a rubber blanket in a groove, for blade contact, protective effect is formed to the cutting edge of blade.
Using method is as follows: be laid on backing plate 3 by open and flat for cotton leaf 4, and by hand-held for the fixed head being fixed with four groups of blades and pressed by top, four groups of blades are just in time stuck in the square indentations of backing plate, and just can obtain rapidly area is 9cm
2blade, claim after dry weight, directly can calculate specific leaf weight.
By the application of above-mentioned sampler, quantitatively can obtain the blade of certain area, the cotton leaf sample for 3cm × 3cm such as, intercepted in the present embodiment.
Embodiment two, as shown in Figures 4 to 7, also comprises an only device for auxiliary pressing, by being arranged on device by above-mentioned fixed head and backing plate, realizes sampling fast, in batches, accurately.
Particularly, as Fig. 4, this device comprises C shape support 5, base plate 6, top board 7 and spring 8, wherein base plate 6 and top board are separately fixed at lower end and the upper end of C shape support 5, and on base plate 6, there are first draw-in groove 61 in central authorities, for square, the profile of size and backing plate 3 matches, top board 7 centre is provided with a circular guide cylinder 71, is provided with a spring fitting step, and is provided with gathering sill wherein in guide cylinder.
