Description

Technical Field

[0001] The invention relates to the technical field of core splitting and sampling, and more specifically to a geological exploration and drilling core splitting and sampling device. Background Art

[0002] Core splitting is an important part of geological exploration. Core splitting refers to the process of splitting the cylindrical core obtained by drilling into two parts along the longitudinal direction or a specific direction. Its purpose is to be able to observe and analyze the rock structure, mineral composition, pore characteristics, etc. inside the core in detail without destroying the overall structural characteristics and representativeness of the core.

[0003] Existing core splitting equipment usually uses mechanical force to push the splitter into the core, and relies on the squeezing force between the splitter and the core to split the core into two semi-cylindrical shapes when the internal stress reaches the limit; however, during the splitting operation, the operator is usually required to manually place the core under the splitter. After the splitting is completed, the operator still needs to manually pick up and collect the core. During this period, there may be a risk of the splitter splitting down, which is easy to cause safety hazards to the operator. In addition, the core may produce fragments due to the impact force. These fragments have a certain speed and energy and may hit the operator's eyes, face or other parts of the body, causing harm to the operator.

[0015] A method for using a geological exploration drilling core splitting device comprises the following steps: S1. Loading operation: when the multifunctional plate assembly is in the unfolded state, the core sample is placed between the two arc-shaped strips of the curved plate 1, and the hydraulic cylinder 2 is operated to pull the tooth plate to slide on the fixed frame. During the sliding process, the tooth plate drives the control gear 2 to rotate clockwise through the upper tooth opening, drives the control gear 1 to rotate counterclockwise through the lower tooth opening 1, and drives the transmission gear to rotate counterclockwise through the lower tooth opening 2. The transmission gear drives the control gear 3 to rotate clockwise, and further drives the feed baffle, the unloading baffle and the upper baffle to gradually form a retracted state. , when the lower baffle rotates 45 degrees clockwise, the lower tooth mouth 2 is separated from the transmission gear. At this time, the lower baffle is in a stationary state, and the bottom of the support frame of the lower baffle contacts the inner bottom surface of the frame. In addition, the feed baffle and the upper baffle continue to rotate. During the rotation of the feed baffle, the inclination of the curved plate 1 gradually increases, so that the core sample rolls along the inner curved surface of the curved plate 1 to the lower end. The core sample rolls into the positioning groove in the support frame through multiple guide bars until the multi-function plate assembly forms a retracted state, completing the feeding operation; S2, splitting operation, through the hydraulic cylinder 1, drives the splitter to split the core sample vertically downward, cutting the core sample into two halves. In the process of splitting the core sample, the flying debris is blocked by the feed baffle and the upper baffle; S3, unloading operation, through the work of hydraulic cylinder 2, push the tooth plate to slide on the fixed frame, during the sliding process, the tooth plate preferentially drives the control gear 1 and the control gear 2 to rotate simultaneously, so that the feed baffle and the upper baffle gradually form an expanded state, when the control gear 1 rotates 45 degrees, the lower tooth mouth 2 contacts with the transmission gear and forms an engaged state, as the tooth plate continues to slide, the lower tooth mouth 2 drives the transmission gear to rotate, and further drives the control gear 3 to rotate, so that the unloading baffle rotates, until the feed baffle, the unloading baffle and the upper baffle complete the expanded state, at this time, the core sample in the support frame is affected by the inclination angle of the support frame, so that the core sample slides out from the positioning groove to the outside of the support frame and enters the material box cart, and at the same time, repeat the loading operation of S1 to perform the splitting operation on the next core sample.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention designs a multifunctional board assembly with an expanded state and a folded state inside the stone splitting assembly. When the multifunctional board assembly is in the folded state, the drilled cylindrical core sample is split into two core samples with semi-cylindrical structures through the stone splitting assembly. In the splitting process, splashing fragments that may be generated on the core are protected by the feed baffle and the upper baffle in the folded state, so that they splash inside and are difficult to splash into the environment outside the stone splitting assembly, thereby effectively protecting the safety of the operator. When the multifunctional board assembly is in the expanded state, the core sample that has been split is affected by the inclination of the unloading baffle in the expanded state and automatically slides out, thereby forming automatic unloading, without the need for the operator to manually unload the material, thereby improving the work efficiency and avoiding the potential safety hazards of manual unloading.

[0017] 2. The present invention designs an adjustment component. When hydraulic cylinder 2 pushes the tooth plate forward to slide on the fixed frame, the tooth plate will preferentially drive control gear 1 and control gear 2 to rotate simultaneously, so that the feed baffle and the upper baffle gradually form an expanded state. As the tooth plate continues to slide, lower tooth mouth 2 contacts and forms an engagement state with the transmission gear. Lower tooth mouth 2 drives the transmission gear to rotate, and further drives control gear 3 to rotate, so that the unloading baffle rotates until the feed baffle, the unloading baffle and the upper baffle complete the expanded state, thereby realizing automatic unloading. When hydraulic cylinder 2 pulls the tooth plate back to slide on the fixed frame, similarly, it can preferentially drive the unloading baffle to rotate and reset, and through the continuous sliding of the tooth plate, it drives the feed baffle and the upper baffle to form a retracted state, forming a protective effect, and the operation is simple and quick.

[0018] 3. The present invention places the core sample on the top surface of the curved plate 1 of the feed baffle in the expanded state. When the feed baffle is controlled by the adjustment component to gradually form a retracted state, the inclination of the curved plate 1 gradually increases, so that the core sample rolls toward the lower end along the inner curved surface of the curved plate 1, and the core sample rolls into the positioning groove in the support frame through a plurality of guide bars until the multi-function plate assembly forms a retracted state to complete the loading operation. The present invention does not require the operator to manually place the core sample under the splitting knife, thereby avoiding possible risks. The core sample is automatically rolled into the support frame by the process of the feed baffle changing from the expanded state to the retracted state, and the cylindrical core sample is rolled into the positioning groove on the bottom surface of the support frame through the arc concave structure of the positioning groove, so as to position and support the cylindrical core sample, thereby improving the accuracy of splitting the sample, simplifying the operating steps of the operator, and ensuring the safety of the operator.

[0019] 4. The present invention designs two arc-shaped bars on the curved plate 1, adjusts the position of the adjustment block on the U-shaped plate, and fixes the adjustment block on the U-shaped plate with a screw, so that the distance between the two arc-shaped bars can be adjusted. The present invention can further adjust the distance between the two arc-shaped bars according to the length of the core sample, and restricts the position of the two ends of the core sample through the two arc-shaped bars, thereby avoiding the deviation of the rolling path of the core sample, and further improving the stability and accuracy of the core sample feeding.
