[0032] A table top 2 is installed on the frame 1, and a cement mold 13 is placed on the top of the table top 2. The cement mold 13 is transparent from top to bottom, and the shape and size can be positioned to meet the needs of sample production.

[0033] The slitting cylinder 5 is installed on the top surface of the top plate 4, and a double-layer mounting frame 7 is installed at the output end of the slitting cylinder 5.

The rotating electric cylinder 81 can be extended to drive the rack 82 to move, thereby driving the gear 83 to rotate, and then realize the angle adjustment. After the adjustment is completed, because the gear 83 is meshed with the rack 82, the gear 83 is not easy to rotate and is at the rotated angle.

[0035] The insertion rail 10 is driven to deflect by the gear 83, and a plurality of slit units 12 are inserted in the insertion rail 10, and the plurality of slit units 12 are assembled into a slit assembly. The slit units 12 are assembled in the insertion rail 10, and the slit units 12 are fixed to the insertion rail 10, and the plurality of slit units 12 are attached to each other, and the plurality of slit units 12 and the insertion rail 10 form a sheet-like slit structure.

Figure 1 and Figure 3 Specifically, it is ensured that the output end of the slitting cylinder 5 is extended to drive the double-layer mounting frame 7 to move downward stably to avoid deviation, thereby ensuring the accuracy of the slitting angle and improving the stability of the device operation.

[0038] As a preferred embodiment, the rotary electric cylinder 81 is mounted on one side of the L-shaped mounting frame 84, and the rack 82 is slidably mounted on the inner surface of the other side of the L-shaped mounting frame 84 through a sliding assembly 85. Figure 1 and Figure 4 , so that the rack 82 moves more smoothly, avoids the rack 82 from falling or tilting outward, and ensures that the rack 82 and the gear 83 are firmly engaged.

[0039] As a preferred embodiment, a stopper assembly 86 is provided on the L-shaped mounting frame 84 to play a blocking and protective role. Figure 4 , the protection of the rack 82 and the rotary electric cylinder 81 is strengthened by blocking.

The middle part of the slitting unit 12 is held to drive the slitting unit 12 to slide to a suitable position. The opening on the bottom surface of the insertion slot 101 is used to accommodate the upper and middle part of the slitting unit 12, so that the slitting unit 12 can slide in the insertion slot 101.

[0041] As a preferred embodiment, a positioning hole 122 is provided on the insertion portion 121, and a positioning pin hole 11 is provided on the insertion rail 10. A positioning pin is inserted into the positioning pin hole 11 and the slitting blade surface 123 to fix the slitting unit 12 to the insertion rail 10. Figure 1 and Figure 3 Specifically, by inserting positioning pins, the fixation between a single slitting unit 12 and the insertion rail 10 is achieved.

[0042] When making cement samples, first pre-place the cement mold 13 to ensure that there are one or more humidity sensors 3 in the lower opening of the cement mold 13 at the bottom of the cement mold 13, then lay a bottom film with openings, and expose the humidity sensors 3 from the openings of the bottom film. Then place the cement mold 13 and add the prepared cement slurry into the cement mold 13.

[0043] According to the cutting requirements, an appropriate amount of cutting units 12 are selected to be assembled on the plug-in rail 10, and the slitting unit 12 is fixed by inserting the locating pin into the locating pin hole 11, and then the rotating electric cylinder 81 is controlled to extend, and the gear 83 is driven to rotate through the rack 82.

After rotating to the required angle, the rotating electric cylinder 81 is turned off to complete the length and angle adjustment.

[0044] The humidity sensor 3 is used to detect the humidity of the cement sample. After the humidity sensor 3 detects that the humidity of the cement sample reaches a threshold value, the slitting cylinder 5 is started, and the slitting cylinder 5 extends downward, driving the double-layer mounting frame 7 to move downward, so that the slitting assembly composed of a plurality of slitting units 12 is buried in the cement sample.

[0047] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0048] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.
