The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0031] See also Figures 1 to 5As shown, the utility model provides a cement sample production device with prefabricated slits of various angles and lengths, comprising: a frame 1, a table 2, a slit cylinder 5, a double-layer mounting frame 7, a rotating mechanism, a plug-in rail 10 and a slit unit 12. Several slit units 12 are assembled and fixed in the plug-in rail 10. The length of the slit structure can be adjusted by changing the number of assemblies. The utility model has strong flexibility and can select an appropriate number of slit units 12 for assembly as needed. In addition, the assembled plug-in rail 10 and the slit unit 12 can be driven to rotate by the rotating mechanism to achieve angle adjustment. Combined with the above-mentioned length adjustment, cement samples with different angles and lengths can be produced, and the overall practicality is strong.

[0032] A table 2 is installed on the frame 1, and a cement mold 13 is placed on the top of the table 2. The cement mold 13 is transparent from top to bottom, and its 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. The output end of the slitting cylinder 5 is installed with a double-layer mounting frame 7. The slitting cylinder 5 can drive the double-layer mounting frame 7 and the structures, mechanisms, components, etc. installed on the double-layer mounting frame 7 to rise and fall.

[0034] The rotating mechanism includes a rotating electric cylinder 81, and a rack 82 is installed at the output end of the rotating electric cylinder 81. The moving rack 82 drives the gear 83 engaged with it to rotate. The rotating electric cylinder 81 can be extended to drive the rack 82 to move, thereby driving the gear 83 to rotate, thereby achieving angle adjustment. After the adjustment is completed, because the gear 83 is engaged 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 by the gear 83 to deflect. A plurality of slitting units 12 are inserted into the insertion rail 10. The slitting units 12 are assembled into a slitting assembly. The slitting units 12 are assembled into the insertion rail 10, fixed to the insertion rail 10, and abutted against each other. The slitting units 12 and the insertion rail 10 form a sheet-like slitting structure.

[0036] As a preferred embodiment, a humidity sensor 3 is provided on the top surface of the table 2. Several humidity sensors 3 can be provided. Figure 1 and Figure 2 Specifically, after placing the cement mold 13 on the table 2, at least one humidity sensor 3 is located in the lower opening of the cement mold 13. When cement is added to the cement mold 13 to make a sample, the humidity sensor 3 can monitor the humidity of the sample, which is convenient for subsequent cutting operations, avoiding the collapse of the cutting seam caused by the cement sample not being formed, and avoiding the phenomenon of excessive forming of cement making it impossible to pull out the unit mold, etc.

[0037] As a preferred embodiment, a through hole is provided on the top plate 4 for the output end of the slitting oil cylinder 5 to pass through, and the guide limit rod 6 installed on the top plate of the double-layer mounting frame 7 passes through the sleeve on the top plate 4. Figure 1 and Figure 3 Specifically, it is necessary to ensure 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 cylinder 81 is mounted on one side of the L-shaped mounting bracket 84, and the rack 82 is slidably mounted on the inner surface of the other side of the L-shaped mounting bracket 84 through the sliding component 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, the L-shaped mounting frame 84 is provided with a stopper assembly 86 for blocking and protecting the mounting frame. Figure 4 , by blocking, the protection of the rack 82 and the rotary cylinder 81 is strengthened.

[0040] As a preferred embodiment, the insertion rail 10 is provided with an insertion slot 101, the insertion slot 101 includes two ports and an opening provided on the bottom surface of the insertion rail 10, the top of the slitting unit 12 is provided with an insertion portion 121, and the bottom surface of the slitting unit 12 is provided with a slitting blade surface 123, combined with Figure 1 and Figure 3 Specifically, the insertion portion 121 is stuck in the insertion slot 101 of the insertion rail 10. When installing the slitting unit 12, the insertion portion 121 can be inserted from the openings at both ends of the insertion slot 101 of the insertion rail 10. The middle part of the slitting unit 12 is held and driven 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. In actual use, after assembling several slitting units 12, positioning pins can be inserted into the slitting units 12 at both ends; positioning pins can also be inserted into each slitting unit 12.

[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 and assembled on the insertion rail 10, and the slitting units 12 are fixed by inserting the positioning pins into the positioning pin holes 11. Then, the rotary electric cylinder 81 is controlled to extend, and the gear 83 is driven to rotate through the rack 82. The rotating shaft of the gear 83 drives the mounting plate 9 and the insertion rail 10 installed with the mounting plate 9 to rotate. After rotating to the required angle, the rotary 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, 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 several slitting units 12 is buried in the cement sample. When the humidity sensor 3 continues to detect the humidity of the cement sample and reaches another threshold, the slitting cylinder 5 is started, and the output end of the slitting cylinder 5 retracts.

In actual use, the cement mold 13 is first installed and the materials required for the specimen are cast. Then, the drying device 14 is fixed on all sides of the cement mold 13, and the sample production device is controlled to make the slitting unit 12 penetrate into the cement mold 13. Finally, the drying device 14 is started before the specimen is heated to speed up the specimen production process.

[0046] Preferably, a stopwatch 15 is provided on the outer surface of the drying device 14. This allows the heating and ventilation times of the drying device 14 to be set during the specimen preparation process. When the preset time is reached, the drying device 14 stops heating and ventilation and sends a message to the experimenter via the wireless network to facilitate the next step.

[0047] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. 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 figures. For example, if the device in the 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.
