Description

Technical Field

[0001] This utility model relates to the field of exploration equipment technology, and in particular to a practical drilling core splitting machine. Background Technology

[0002] In the field of core sampling during geological exploration drilling, precise core cutting is a crucial step in obtaining effective geological information. Traditional core cutting often employs handheld cutting machines, which has significant technical drawbacks: Firstly, the operation relies entirely on manual fixation of the core and stabilization of the equipment, making it difficult to achieve precise half-axial splitting, resulting in a reduced effective sample collection rate and directly affecting sampling accuracy. Secondly, when cutting without fixing the core, slippage and displacement can easily occur when the cutting blade contacts the core, posing a safety hazard. Utility Model Content

[0003] The purpose of this invention is to provide a practical drilling core splitting machine to solve the problems of unstable core fixation, low cutting efficiency, and insufficient sampling accuracy in existing core cutting technologies.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A practical core drilling splitting machine includes a cutting machine body movably mounted on a cutting base. The cutting base includes two longitudinally spaced transverse frames, the tops of which are beveled. A stiffening rod is provided between the bottoms of the two transverse frames to form a quadrilateral bottom structure, improving the stability of the splitting machine. Two mounting rods are provided transversely spaced between the tops of the two transverse frames, and a mounting plate is provided between the two mounting rods. A mounting seat is provided on the top right side of the mounting plate. The bottom right side of the cutting machine body is hinged to the mounting seat by a pin. A slot is provided on the mounting plate for the cutting blade of the cutting machine body to pass through. A cutting guide groove is inclinedly provided below the cutting machine body and is fixedly connected to the cutting base.

[0006] Furthermore, a support rod is provided between the right sides of the two transverse frames, and the two ends of the cutting guide groove are respectively fixedly connected to the mounting rod and the support rod on the left side.

[0007] Furthermore, a water spray assembly is provided on the front side of the cutting machine body. The water spray assembly includes a water spray pipe fixedly connected to the mounting plate. Several water spray heads are connected to the circumferential surface of the water spray pipe facing the cutting machine body, and a water pipe connector is connected to one end of the water spray pipe for connecting an external water pipe to supply water to the water spray pipe 61. Water is sprayed onto the cutting blade of the cutting machine body through the water spray pipe, protecting the cutting blade while reducing dust pollution.

[0008] Furthermore, a baffle is provided on the left side of the cutting machine body, and the baffle is bolted to the mounting rod on the right side to block the mud splashing out to the longitudinal sides and the right side.

[0009] Furthermore, a splash guard is provided on the upper right side of the cutting guide groove. The splash guard is fixedly connected to the cutting guide groove to block the mud splashed out from the right side of the cutting guide groove.

[0010] Furthermore, a pushing mechanism is provided on the left side of the cutting machine body. The pushing mechanism includes a slide rod, the two ends of which are fixedly connected to two transverse frames. Two sliders are slidably connected to the slide rod. A connecting rod is hinged to the left side of each slider. The left side of the two connecting rods is hinged to the same connecting block. An L-shaped grip is fixedly connected to the lower part of the connecting block. A top block is fixedly connected to the right side of the L-shaped grip. The top block can slide in contact with the cutting guide groove. A return spring is fixedly connected between the slider and the transverse frame, and the return spring is sleeved on the slide rod.

[0011] By adopting the above technical solution, this utility model has the following beneficial effects:

[0012] 1. This utility model, through the design of an inclined cutting base and cutting guide groove, allows the rock core to be placed on the cutting guide groove during operation and pushed along it for cutting. The cutting guide groove can limit and fix the rock core on both sides, ensuring the stability and safety of the cutting process and facilitating the splitting of the rock core in half. The inclined design of the cutting guide groove not only reduces the force required to push the rock core, making the cutting operation more labor-saving and improving the efficiency of rock core cutting, but also facilitates the smooth discharge of wastewater and rock chips generated during the cutting process.

[0013] 2. This utility model cuts the rock core by pushing the top block of the pushing mechanism against it and moving the rock core. After cutting, the pushing mechanism can automatically reset, avoiding the need to push the rock core directly by hand, thus improving the safety of the splitting machine and preventing accidents.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Example 1

[0022] See Figures 1-3 This embodiment of a practical core drilling splitting machine includes a cutting machine body 1, a cutting base 2, and a cutting guide groove 4. Wherein:

[0023] The cutting machine body 1 can be movably mounted on the cutting base 2. It should be noted that the cutting machine body 1 is an application of existing technology. Specifically, various brands or models of cutting machines with a power generally greater than 1500W can be selected to ensure sufficient power for cutting rock core samples of different hardness. The cutting blade selected for the cutting machine body 1 can be made of diamond material.

[0024] The cutting base 2 is a frame structure welded from angle steel, specifically including transverse frames 21, stiffening rods 22, mounting rods 23, and support rods 24. Two transverse frames 21 are spaced longitudinally, forming right-angled trapezoidal frames with sloping tops. A stiffening rod 22 is positioned between the bottoms of the two transverse frames 21 to form a quadrilateral bottom structure, improving the stability of the splitting machine. Two mounting rods 23 are spaced laterally between the tops of the two transverse frames 21. A mounting plate 3 is positioned between the two mounting rods 23. A mounting base 5 is welded and fixed to the top right side of the mounting plate 3. The bottom right side of the cutting machine body 1 is hinged to the mounting base 5 via a pin, facilitating installation, disassembly, and maintenance. The mounting plate 3 has a slot 31 (not shown in the figure) for the cutting blade of the cutting machine body 1 to pass through. The support rod 24 is positioned between the right sides of the two transverse frames 21. Preferably, as shown... Figure 3 The diagram shows some of the dimensions of the cutting base 2, in cm.

[0025] A cutting guide groove 4 for placing the rock core is inclinedly provided at the bottom of the cutting machine body 1. The two ends of the cutting guide groove 4 are welded and fixed to the mounting rod 23 and the support rod 24 on the left side, respectively. The cutting guide groove 4 is specifically a V-shaped groove or a U-shaped groove, which clamps and supports the rock core and limits the rock core on both sides to ensure that the rock core does not move to the sides. During operation, the rock core is placed on the cutting guide groove 4, the cutting machine body 1 is started, and the rock core is pushed by hand to move it along the cutting guide groove 4 from left to right, so that the cutting blade of the cutting machine body 1 splits the rock core in half. The cut rock core is taken out from the right side of the cutting guide groove 4.

[0026] As a preferred embodiment, such as Figure 5 As shown, a water spray assembly 6 is installed on the front side of the cutting machine body 1. The water spray assembly 6 includes a water spray pipe 61 and a water pipe connector 63. The right end of the water spray pipe 61 is fixedly welded to the mounting plate 3 via a support. Several water spray heads 62 are connected to the circumference of the water spray pipe 61 facing the cutting machine body 1, and the several water spray heads 62 are arranged at equal intervals along its length. The right end of the water spray pipe 61 is also connected to a water pipe connector 63, which is used to connect an external water pipe to supply water to the water spray pipe 61. During operation, water is sprayed from the several water spray heads 62 onto the cutting blade of the cutting machine body 1, cooling the cutting blade and reducing dust generated during the cutting process. This prevents excessive dust from damaging the cutting blade and affecting the cutting effect, thereby improving the service life of the splitting machine.

[0027] In a preferred embodiment, a baffle 7 is provided on the left side of the cutting machine body 1, and the baffle 7 is bolted to the mounting rod 23 on the right side. Simultaneously, a splash guard 8 is provided above the right side of the cutting guide groove 4. The splash guard 8 is an arc-shaped cylinder, and its bottom end is fixedly welded to the transverse outer side of the cutting guide groove 4. The baffle 7 and the splash guard 8 allow the core sample to be shielded from mud splashing to the longitudinal sides and right side during cutting, protecting the operator from being splashed and improving the practicality of the splitting machine.

[0028] Example 2

[0029] Based on the solution of Embodiment 1 described above, the splitting machine of Embodiment 2 adds a pushing mechanism 9. Specifically, as shown... Figure 4As shown, the pushing mechanism 9 is located on the left side of the cutting machine body 1. The pushing mechanism 9 includes a slide rod 91, the two ends of which are fixedly welded to two transverse frames 21. Two sliders 92 are slidably connected to the slide rod 91. A return spring 97 is fixedly connected between the sliders 92 and the transverse frames 21, and the return spring 97 is sleeved on the slide rod 91. A connecting rod 93 is hinged to the left side of each of the two sliders 92. The left side of the two connecting rods 93 is hinged to the same connecting block 94. An L-shaped grip 95 is fixedly connected to the lower part of the connecting block 94. A top block 96 is fixedly connected to the right side of the L-shaped grip 95. The bottom of the top block 96 is adapted to the shape of the cutting guide groove 4 and can slide in contact with the cutting guide groove 4. During operation, the core is placed on the cutting guide groove 4. Then, the L-shaped handle 95 is pulled to make the top block 96 abut against the left side of the core. Then, the L-shaped handle 95 is pushed to make the two sliders 92 slide along the longitudinal sides and the return spring 97 is compressed. The top block 96 abuts against the core and pushes the core to move for cutting. After cutting, the return spring 97 returns to its original position and the top block 96 returns to its original position. This avoids pushing the core directly by hand, prevents safety accidents, and improves the safety of the splitting machine.
