At the same time, too much manual intervention makes it difficult to control the processing rhythm, and the processing cycle of a single sample is too long. When facing the demand for batch samples, the low efficiency of the traditional method is particularly prominent, and it cannot meet the timeliness requirements of scientific research projects or engineering detection.

DETAILED DESCRIPTION

[0021] Embodiments of the present application are described in detail below with reference to the attached drawing figures, wherein the same or like reference numerals used in different figures refer to the same or like components. The embodiments described below are merely exemplary for the purposes of explanation and are not to be understood as limiting the present application.

[0022] In the present application, unless otherwise explicitly specified and limited, a first feature is "on" or "under" a second feature can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature is "above", "over" and "on top of" the second feature can be that the first feature is directly above or obliquely above the second feature, or only means that the first feature is horizontally higher than the second feature. The first feature is "below", "under" and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or only means that the first feature is horizontally lower than the second feature.

[0023] In the field of rock sample processing and molding technology, the molding processing of columnar rock samples is a key pre-step for carrying out rock mechanics tests. Such tests (such as uniaxial compressive strength test, elastic modulus determination, etc.) have very high requirements for sample size accuracy, and the original rock taken from the field needs to be processed into columnar samples of specific specifications through cutting, polishing and other processes to ensure the accuracy and reliability of the test data. The traditional molding equipment has significant limitations in the processing process: the operator needs to first cut the rock raw material into a roughly columnar shape through a cutting device, and then transfer it to a polishing device for end face flattening and outer wall smoothness processing. The step-by-step operation of the two processes not only prolongs the processing period of a single sample, reduces the overall test preparation efficiency, but also faces serious safety and maintenance problems in actual operation. A large amount of rock debris and dust generated during cutting and polishing will splatter irregularly, not only easily adhering to the surface of the equipment's precision components causing wear and tear or failure, affecting the service life of the equipment, but also diffusing in the operating environment, posing a direct threat to the respiratory system and eye health of the operator, and there is a great occupational safety hazard. In view of this, the columnar rock sample molding equipment developed by the present invention realizes the flow operation of cutting and polishing through a series of innovative designs, and the specific implementation is as follows: Example one: as Figures 1-3As shown, a cylindrical rock sample forming device includes a forming box 1. One end of the forming box 1 is connected to a conveying component 2. The conveying component 2 conveys the rock sample via a conveying motor, pulleys, and a belt structure. The conveying component 2 is used to centrally transport the extracted rock sample into the forming box 1 for centralized processing. A processing disc 3 is rotatably engaged inside the forming box 1. Multiple feeding slots 4 are provided on the circular side wall of the forming box 1. Multiple clamping components 5 are provided inside the processing disc 3. The clamping components 5 are used to precisely clamp the rock sample and then rotate it for cutting and grinding. The clamping components 5 include a first servo motor 51 disposed inside the processing disc 3. A rotating rod 52 is fixedly disposed on the output shaft of the first servo motor 51. The rotating rod 52 is rotatably connected to the processing disc 3. A first drive gear 53 and a second drive gear 54 are sequentially disposed on the outer surface of the rotating rod 52. The processing disc 3... Multiple processing grooves 55 are formed on the circular sidewall. Each processing groove 55 is adapted to a corresponding feeding groove 4 to complete the feeding, cutting, grinding and unloading operations, forming a streamlined construction process. The upper and lower ends of the processing groove 55 are symmetrically rotatably equipped with a first driven gear 56 and a second driven gear 57. The first driven gear 56 and the second driven gear 57 are respectively meshed with a first driving gear 53 and a second driving gear 54. Both the first driven gear 56 and the second driven gear 57 are rotatably connected to the processing disk 3. The upper end of the first driven gear 56 is equipped with a first hydraulic telescopic cylinder 58. The end of the first hydraulic telescopic cylinder 58 extends to the bottom of the first driven gear 56 and is equipped with a clamping plate 59. The lower end of the clamping plate 59 is equipped with an elastic pad layer, which uses the elastic deformation of the material to disperse the clamping force and avoid excessive local stress that could cause the rock to crack; at the same time, it increases the friction to prevent the sample from sliding. In this embodiment, the first hydraulic telescopic cylinder 58 drives the clamping plate 59 to clamp and fix the rock sample. After the clamping is stable, the first servo motor 51 drives the first drive gear 53 and the second drive gear 54 to rotate through the rotating rod 52. Thus, the first drive gear 53 and the second drive gear 54 drive the first drive gear 53 and the second drive gear 54 that mesh with it to rotate, so as to realize the uniform rotation of the clamped rock sample. During the uniform rotation, the rock sample is formed and processed in sequence by the cutting and grinding device, thereby improving work efficiency.

[0024] Furthermore, such as Figure 4 As shown, the outer surface of the forming box 1 is equipped with processing components 6 on the outside of the two feeding troughs 4. The two processing components 6 sequentially complete the cutting and grinding operations of the rock sample. According to relevant industry specifications, combined with experimental standard requirements, equipment technical parameters and processing capabilities, and taking into full account the characteristics of the rock itself (such as particle size distribution and homogeneity), a comprehensive adjustment is made to determine the forming size of the columnar rock sample. The core principle is to ensure that the sample is representative, the experimental data is accurate and reliable, and the operation process is feasible.

[0025] Specific size selection can refer to the following common specifications: small size sample: diameter 50mm, height 100mm, suitable for general uniaxial compressive strength, triaxial compression and other basic mechanics experiments; medium size sample: diameter 75mm, height 150mm, mainly used for large particle size rock testing or higher precision experimental scenarios; large size sample: diameter 100mm and above, height 200mm and above, mainly used for simulating the mechanical properties of large volume rock in the field, and requires special large equipment for processing and testing. During the field sampling stage, the initial size of the rock sample is usually large, and if it is directly polished, it will significantly increase the working hours. Therefore, it is recommended to first cut the sample into a cylinder by the cutting device, so that its diameter is slightly larger than the target sample size, and then precise polishing is performed to improve the processing efficiency and accuracy of the sample.
