Description

Technical Field

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

[0002] Core splitting is an important link in the process of geological exploration. Core splitting refers to the operation process of dividing the cylindrical core obtained by drilling into two parts along the longitudinal direction or a specific direction. The 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 devices usually use mechanical force to push the splitting knife into the core, and rely on the extrusion force between the splitting knife and the core to cause the core to split into two semi-cylindrical shapes when the internal stress reaches the limit. However, during the splitting operation, usually, the operator needs to manually place the core under the splitting knife, and 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 splitting knife descending, which is likely to pose a safety hazard to the operator. Moreover, the core may generate fragment splashing 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. In view of this, we propose a core splitting device for geological exploration drilling. Summary of the Invention

The material box trolley is used to receive the core sample in a semi-cylindrical structure that slides out of the inside of the supporting frame.

[0015] A method for using a geological exploration drilling core splitting device includes the following steps:

[0016] S1. Loading operation: When the multi-functional plate assembly is in the unfolded state, place the core sample between the two arc-shaped bars of the first curved plate. By operating the second hydraulic cylinder, pull the toothed plate to slide on the fixed frame. During the sliding process of the toothed plate, drive the second control gear to rotate clockwise through the upper tooth opening, drive the first control gear to rotate counterclockwise through the first lower tooth opening, and drive the transmission gear to rotate counterclockwise through the second lower tooth opening. The transmission gear drives the third control gear to rotate clockwise, and further drives the feeding baffle, the discharging baffle, and the upper baffle to gradually form a closed state. When the discharging baffle rotates 45 degrees clockwise, the second lower tooth opening is separated from the transmission gear. At this time, the discharging baffle forms a stationary state, and the bottom of the supporting frame of the discharging baffle contacts the inner bottom surface of the machine frame. Moreover, the feeding baffle and the upper baffle continue to rotate. During the rotation of the feeding baffle, the inclination of the first curved plate gradually increases, so that the core sample rolls along the inner curved surface of the first curved plate towards the lower end. The core sample rolls into the positioning groove in the supporting frame through multiple guiding bars until the multi-functional plate assembly forms a closed state, completing the loading operation;

[0017] S2. Core splitting operation: By operating the first hydraulic cylinder, drive the splitting knife to cut the core sample vertically downward, cutting the core sample into two halves. During the process of cutting the core sample, the splashing debris is blocked by the feeding baffle and the upper baffle;

[0018] S3. Unloading operation: By operating the second hydraulic cylinder, push the toothed plate to slide on the fixed frame. During the sliding process of the toothed plate, first drive the first control gear and the second control gear to rotate simultaneously, so that the feeding baffle and the upper baffle gradually form an unfolded state. When the first control gear rotates 45 degrees, the second lower tooth opening contacts and meshes with the transmission gear. As the toothed plate continues to slide, the second lower tooth opening drives the transmission gear to rotate, further driving the third control gear to rotate, causing the discharging baffle to rotate until the feeding baffle, the discharging baffle, and the upper baffle complete the unfolded state. At this time, affected by the inclination angle of the supporting frame, the core sample in the supporting frame slides out of the positioning groove to the outside of the supporting frame and into the material box trolley. At the same time, repeat the loading operation in S1 to perform the core splitting operation on the next core sample.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The present invention designs a multi-functional plate assembly with a deployed state and a retracted state inside the rock splitting assembly. When the multi-functional plate assembly is in the retracted state, the cylindrical core sample drilled is split into two semi-cylindrical core samples by the rock splitting assembly. During the splitting process, the flying debris that may be generated on the core is enclosed by the retracted feeding baffle and the upper baffle, causing it to fly inside and making it difficult to fly into the environment outside the rock splitting assembly, effectively protecting the safety of the operator. When the multi-functional plate assembly is in the deployed state, the core sample after splitting slides out automatically under the influence of the inclination generated by the deployed blanking baffle itself, forming automatic blanking. There is no need for the operator to manually blank, which not only improves work efficiency but also avoids potential safety hazards in manual blanking.

[0021] 2. The present invention designs an adjustment assembly. When the second hydraulic cylinder pushes the toothed plate to slide on the fixed frame forward, the toothed plate will first drive the control gear one and the control gear two to rotate simultaneously, causing the feeding baffle and the upper baffle to gradually form a deployed state. As the toothed plate continues to slide, the lower tooth opening two contacts and meshes with the transmission gear, and the lower tooth opening two drives the transmission gear to rotate, further driving the control gear three to rotate, causing the blanking baffle to rotate until the feeding baffle, the blanking baffle, and the upper baffle complete the deployed state, realizing automatic blanking. When the second hydraulic cylinder pulls the toothed plate to slide on the fixed frame back, similarly, it can first drive the blanking baffle to rotate back to its original position, and through the continuous sliding of the toothed plate, it further drives the feeding baffle and the upper baffle to form a retracted state, forming an enclosing effect, and the operation is simple and fast.

[0022] 3. The present invention places the core sample on the top surface of the curved plate one of the deployed feeding baffle. When the feeding baffle is gradually controlled by the adjustment assembly to form a retracted state, the inclination of the curved plate one gradually increases, causing the core sample to roll along the inner curved surface of the curved plate one towards the lower end. The core sample rolls into the positioning groove in the supporting frame through multiple guiding strips until the multi-functional plate assembly forms a retracted state, completing the feeding operation. This enables the present invention to avoid the need for the operator to manually place the core sample under the splitting knife, thereby avoiding potential risks. Through the process of the feeding baffle changing from the deployed state to the retracted state, the core sample is driven to automatically roll into the supporting frame, and through the arc concave surface structure of the positioning groove, the cylindrical core sample rolls to the positioning groove on the inner bottom surface of the supporting frame, forming positioning and support for the cylindrical core sample, which not only improves the accuracy of sample splitting, simplifies the operation steps of the operator, but also ensures the safety of the operator.

[0023] 4. In the present invention, two arc-shaped strips are designed on the first curved plate. By adjusting the position of the adjusting block on the U-shaped plate and fixing the adjusting block on the U-shaped plate with a screw, the distance between the two arc-shaped strips can be adjusted. Further, the present invention can adjust the distance between the two arc-shaped strips according to the length of the core sample. The positions of both ends of the core sample are restricted by the two arc-shaped strips, avoiding the deviation of the rolling path of the core sample, and further improving the stability and accuracy of feeding the core sample.

[0045] Example 1, as Figures 1 to 12 shown, a geological exploration drilling core splitting device related to the present invention includes a stone splitting assembly 1, a multifunctional plate assembly 2 is arranged inside the stone splitting assembly 1, and an adjusting assembly 3 is arranged on the side wall of the stone splitting assembly 1.

[0046] In an embodiment of the present invention, the rock splitting assembly 1 is used to split a drilled cylindrical core sample into two core samples with a semi-cylindrical structure; the multi-functional plate assembly 2 is composed of a feeding baffle 21, a discharging baffle 22 and an upper baffle 23; the adjusting assembly 3 is used to control the feeding baffle 21, the discharging baffle 22 and the upper baffle 23 to form an unfolded state or a folded state; in the unfolded state, the feeding baffle 21 is used for feeding, and the discharging baffle 22 is used for discharging; in the folded state, the feeding baffle 21 and the upper baffle 23 are used to enclose the inside of the rock splitting assembly 1, and the discharging baffle 22 is used for centering and supporting the cylindrical core sample; by designing the multi-functional plate assembly 2 with an unfolded state and a folded state inside the rock splitting assembly 1 in the present invention, when the multi-functional plate assembly 2 is in the folded state, the drilled cylindrical core sample is split into two core samples with a semi-cylindrical structure by the rock splitting assembly 1. During the splitting process, the flying debris that may be generated on the core is protected by the folded feeding baffle 21 and the upper baffle 23, so that it splashes inside and is difficult to splash into the environment outside the rock splitting assembly 1, effectively protecting the safety of the operator. When the multi-functional plate assembly 2 is in the unfolded state, the split core sample slides out automatically under the influence of the inclination generated by the unfolded discharging baffle 22 itself, forming automatic discharging without manual discharging by the operator, which not only improves the work efficiency but also avoids the potential safety hazards of manual discharging.

[0047] As another embodiment of the present invention, the rock splitting assembly 1 includes a frame 101, a first hydraulic cylinder 102 is arranged at the top of the frame 101, the output end of the first hydraulic cylinder 102 is connected with a movable plate 103, a splitting knife 104 is connected to the bottom of the movable plate 103, two ends of the top surface of the movable plate 103 are symmetrically arranged with sliders 105, a chute is arranged on the side wall of the slider 105, and a slide bar 106 that matches the shape of the chute is arranged on the inner side wall of the frame 101. The movable plate 103 is slidably matched with the slide bar 106 through the slider 105. By the operation of the first hydraulic cylinder 102, the splitting knife 104 is driven to split the core sample vertically downward, cutting the core sample into two halves. During the downward splitting process of the splitting knife 104, the movable plate 103 at its top slides downward along the slide bar 106 through the slider 105, which can ensure the verticality of the downward splitting of the splitting knife 104 and improve the stability of the downward splitting of the splitting knife 104.

[0048] As another embodiment of the present invention, the adjusting assembly 3 includes a second hydraulic cylinder 301, a control gear one 303, a control gear two 304, a transmission gear 305, a control gear three 306 and a toothed plate 307. The adjusting assembly 3 further includes a fixed frame 302 arranged on the outer side wall of the frame 101;

[0049] Among them, the second hydraulic cylinder 301 is arranged on the outer wall of the frame 101, and the first control gear 303, the second control gear 304, the transmission gear 305 and the third control gear 306 are respectively arranged movably on the outer wall of the frame 101; the output end of the second hydraulic cylinder 301 is connected with a toothed plate 307, and the toothed plate 307 is respectively meshed and connected with the first control gear 303 and the second control gear 304. The toothed plate 307 and the transmission gear 305 have a separated state and a meshed state, and the transmission gear 305 and the third control gear 306 are meshed and connected;

[0050] Furthermore, the fixing frame 302 is composed of two fixing blocks 3021 and two sliding rods 3022. The two fixing blocks 3021 are symmetrically arranged on the outer wall of the frame 101, and the sliding rods 3022 are arranged between the two fixing blocks 3021; a plurality of sliding plates 3071 are integrally formed on the side wall of the toothed plate 307, and sliding holes matching the sliding rods 3022 are formed on the side wall of the sliding plates 3071. The sliding plates 3071 are slidably matched with the sliding rods 3022 through the sliding holes, and the toothed plate 307 is slidably matched with the fixing frame 302 through the sliding plates 3071; an upper tooth opening 3072 meshed with the second control gear 304 is arranged on the top surface of the toothed plate 307, a first lower tooth opening 3073 meshed with the first control gear 303 is arranged on the bottom surface of the toothed plate 307, and a second lower tooth opening 3074 is also arranged on the bottom surface of the toothed plate 307. When the toothed plate 307 slides forward along the sliding rod 3022, the second lower tooth opening 3074 contacts the transmission gear 305 to form a meshed state. When the toothed plate 307 slides back along the sliding rod 3022, the second lower tooth opening 3074 gradually forms a separated state from the transmission gear 305, so that the toothed plate 307 and the transmission gear 305 have a meshed state and a separated state.

[0051] In the present invention, by designing the adjusting assembly 3, when the second hydraulic cylinder 301 pushes the toothed plate 307 to slide on the fixing frame 302 forward, the toothed plate 307 will first drive the first control gear 303 and the second control gear 304 to rotate simultaneously, so that the feeding baffle 21 and the upper baffle 23 gradually form an unfolded state. When the first control gear 303 rotates by 45 degrees, the second lower tooth opening 3074 contacts the transmission gear 305 and forms a meshed state. As the toothed plate 307 continues to slide, the second lower tooth opening 3074 drives the transmission gear 305 to rotate, further driving the third control gear 306 to rotate, so that the blanking baffle 22 rotates until the feeding baffle 21, the blanking baffle 22 and the upper baffle 23 are in an unfolded state, realizing automatic blanking. When the second hydraulic cylinder 301 pulls the toothed plate 307 to slide on the fixing frame 302 back, similarly, it can first drive the blanking baffle 22 to rotate and reset, and through the continuous sliding of the toothed plate 307, further drive the feeding baffle 21 and the upper baffle 23 to form a closed state, forming a protective effect. The operation is simple and fast, which can not only improve work efficiency, but also provide a relatively safe working environment for the splitting operation.

The blanking baffle 22 includes a supporting frame 2201. A positioning groove 2202 is arranged on the inner bottom surface of the supporting frame 2201. The positioning groove 2202 is set as an arc concave surface structure, and the arc concave surface structure is used to guide the cylindrical core sample to roll onto the inner bottom surface of the supporting frame 2201 into the positioning groove 2202, so as to position and support the cylindrical core sample. The side wall of the supporting frame 2201 is rotatably connected to the inner side wall of the frame 101 through a second rotating rod 2203. The second rotating rod 2203 penetrates through the side wall of the frame 101 and is connected to the third control gear 306.

In the present invention, the core sample is placed on the top surface of the first curved plate 2103 of the feeding baffle 21 in the unfolded state. When the feeding baffle 21 is gradually controlled by the adjusting assembly 3 to form a folded state, the inclination degree of the first curved plate 2103 gradually increases, so that the core sample rolls along the inner curved surface of the first curved plate 2103 to the lower end. The core sample rolls into the positioning groove 2202 in the supporting frame 2201 through a plurality of guiding strips 2104 until the multi-functional plate assembly 2 forms a folded state, completing the feeding operation. This enables the present invention to avoid the need for an operator to manually place the core sample under the splitting knife 104, thereby avoiding possible risks. Through the process of the feeding baffle 21 changing from the unfolded state to the folded state, the core sample is automatically rolled into the supporting frame 2201, and through the arc concave surface structure of the positioning groove 2202, the cylindrical core sample rolls onto the inner bottom surface of the supporting frame 2201 into the positioning groove 2202, positioning and supporting the cylindrical core sample, which not only improves the accuracy of sample splitting, simplifies the operation steps of the operator, but also ensures the safety of the operator.

The arc-shaped strip 2108 is a long arc-shaped plate structure. The arc-shaped strip 2108 is used to guide the core sample to roll along the inner curved surface of the first curved plate 2103 towards the lower end, restricting the positions of both ends of the core sample and preventing the rolling path of the core sample from shifting. A plurality of screw holes 2106 are formed in the side walls of the U-shaped plate 2105. A rotating handle 2109 is arranged on the side wall of the adjusting block 2107.

The screw rod 2110 penetrates through the side wall of the adjusting block 2107 and extends into the screw hole 2106 in the side wall of the U-shaped plate 2105. By designing two arc-shaped strips 2108 on the first curved plate 2103, adjusting the position of the adjusting block 2107 on the U-shaped plate 2105, and fixing the adjusting block 2107 on the U-shaped plate 2105 with the screw rod 2110, the distance between the two arc-shaped strips 2108 can be adjusted.

A baffle strip 2304 is integrally formed at the top of the second curved plate 2303. The baffle strip 2304 can further improve the shielding effect on the splashing fragments.

[0055] As another embodiment of the present invention, a plurality of curved rods 107 are connected to the side wall of the frame 101. The top of the curved rod 107 is connected with a supporting plate 108. The top of the supporting plate 108 is set as an arc-shaped structure. The supporting plate 108 is used to support the first curved plate 2103 in the unfolded state. A material box trolley 4 is arranged on the side of the frame 101. The material box trolley 4 is a product of the prior art in the example. The top of the material box trolley 4 is arranged below the supporting frame 2201. The material box trolley 4 is used to receive the semi-cylindrical core sample that slides out from inside the supporting frame 2201.

Through the operation of the second hydraulic cylinder 301, pull the toothed plate 307 to slide on the fixed frame 302. During the sliding process of the toothed plate 307, drive the second control gear 304 to rotate clockwise through the upper tooth opening 3072, drive the first control gear 303 to rotate counterclockwise through the first lower tooth opening 3073, and drive the transmission gear 305 to rotate counterclockwise through the second lower tooth opening 3074. The transmission gear 305 drives the third control gear 306 to rotate clockwise. Further, drive the feeding baffle 21, the discharging baffle 22, and the upper baffle 23 to gradually form a closed state. When the discharging baffle 22 rotates 45 degrees clockwise, the second lower tooth opening 3074 and the transmission gear 305 are in a separated state. At this time, the discharging baffle 22 is in a stationary state, and the bottom of the supporting frame 2201 of the discharging baffle 22 contacts the inner bottom surface of the frame 101. And, the feeding baffle 21 and the upper baffle 23 continue to perform rotational motion. During the rotation of the feeding baffle 21, the inclination of the first curved plate 2103 gradually increases, so that the core sample rolls along the inner curved surface of the first curved plate 2103 towards the lower end. The core sample rolls into the positioning groove 2202 in the supporting frame 2201 through a plurality of guiding strips 2104 until the multi-functional plate assembly 2 forms a closed state, completing the loading operation;

[0058] S2. Core splitting operation: Through the operation of the first hydraulic cylinder 102, drive the splitting knife 104 to cut the core sample vertically downward, cutting the core sample into two halves. During the process of cutting the core sample, the splashing debris is blocked by the feeding baffle 21 and the upper baffle 23;

[0059] S3. Unloading operation: Through the operation of the second hydraulic cylinder 301, push the toothed plate 307 to slide on the fixed frame 302. During the sliding process of the toothed plate 307, first drive the first control gear 303 and the second control gear 304 to rotate simultaneously, so that the feeding baffle 21 and the upper baffle 23 gradually form an unfolded state. When the first control gear 303 rotates 45 degrees, the second lower tooth opening 3074 contacts and meshes with the transmission gear 305. As the toothed plate 307 continues to slide, the second lower tooth opening 3074 drives the transmission gear 305 to rotate, further driving the third control gear 306 to rotate, causing the discharging baffle 22 to rotate until the feeding baffle 21, the discharging baffle 22, and the upper baffle 23 are in the unfolded state. At this time, the core sample in the supporting frame 2201 slides out of the supporting frame 2201 from the positioning groove 2202 under the influence of the inclination angle of the supporting frame 2201 and enters the material box trolley 4. At the same time, repeat the loading operation of S1 to perform the core splitting operation on the next core sample.
