Description

Technical Field

[0001] The invention relates to the technical field of core splitting machines, in particular to a core splitting machine. Background Art

[0002] A core splitting machine, also known as a core splitter, is a mechanical device used to split the core during the core sampling process. It cuts the core sample column obtained by drilling, and then judges, studies and tests the cut core sample column, analyzes the composition of the sample column, and provides laboratory data and plans for subsequent mineral exploration and mining.

[0003] When existing core splitting machines cut different types of core columns, manual labor is required to assist them in completing the work during the core splitting process. For example, after the core column is split, it will fall at a designated location, but different types of cores need to be stored separately. Falling at the same location can easily cause confusion, which requires staff to constantly pick up cores manually, which makes the core cutting efficiency low. At the same time, when cutting, one end of the core column needs to be held to operate, which is inconvenient to use. Therefore, further optimization is made to the above problems. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a core splitting machine, which is convenient for distinguishing and transporting the core column to the designated position after the core column is cut, avoiding the problem of mixing caused by falling at the same position, and at the same time avoiding manual replacement of core column samples and reducing the situation of holding the core column for operation, thereby improving the efficiency of core column cutting.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a core splitting machine, comprising a frame, a top cover and legs, the top cover is slidably connected in a slideway opened at the top of the frame, the legs are fixedly connected at the four corners of the bottom of the frame, a partition is provided inside the frame, a driving block is provided in the middle of the back of the partition, the output end of the driving block passes through the partition and is fixedly connected to a cutting blade, a core barrel is fixedly connected to the top of the left side of the frame, the other end of the core barrel extends obliquely to the inside of the frame and is clamped on the surface of the cutting blade, a collecting plate is fixedly connected to the right side wall inside the frame and below the core barrel, and the collecting plate is connected to the outlet opened at the bottom right of the frame; A transmission component for conveying core columns is provided at the outlet portion on the right side of the frame, a bracket is fixedly connected to the top of the right side of the frame, and a bottom end of the bracket is fixedly connected to the right end of the transmission component, a positioning plate is provided on the left side of the frame near the core barrel, a material replacement component for replacing core columns is provided on the surface of the positioning plate, and the transmission component drives the material replacement component to rotate along the surface of the positioning plate.

[0006] The present invention has the following beneficial effects: The core splitting machine can put a core column into a core barrel, and the driving block drives the cutting blade to rotate. The core barrel is arranged in an inclined manner, and the core column slides downward by its own gravity, so as to cooperate with the cutting blade to perform mid-cutting, thereby reducing the need for workers to hold the other end of the core column. The cut core column slides onto the surface of the transmission component through the collection plate, and the transmission component can be used to transport the mid-cut core column to the front and rear ends of the right side of the frame, so as to facilitate the distinguishing and preservation of different types of core columns, reduce the mixing of core column samples, and facilitate the collection of workers, thereby improving work efficiency. The core splitting machine can store water in the water storage chamber. When the core column is cut, the water in the water storage chamber is transported to the position of the cutting blade through the connecting pipe 1, which is convenient for cooling the cutting blade and reducing the dust generated when the core column is cut. Since the water outlet position of the connecting pipe 1 is higher than the drainage position, the water flows from top to bottom and flows out from the other end of the connecting pipe 1, close to the cutting blade, reducing the consumption of energy (here refers to the water pump and electricity) when using the water source. A core splitting machine, when the core column is cut, the core sample slides onto the surface of the conveyor belt through the collecting plate by its own gravity, and then the motor is started (forward or reverse), which can drive the roller to rotate and synchronously drive the conveyor belt to move, so that the next isolation belt position corresponds to the outlet position, which is convenient for conveying the core sample to the designated position. Different types of core samples can be distinguished through the isolation belt to avoid mixing; The core splitting machine, when the drum rotates, synchronously drives the gear rod, driving rod one, driving rod two, driving rod three, driving rod four, driving rod five, driving rod six and the gear to rotate, and drives the roller to rotate at the same time. Since the fixing belt is wrapped around the surface of the roller, the fixing belt drives the clamping part to move along the surface of the positioning plate at the same time; the core column can be placed in advance inside the fixing cylinder, and when the position of the next isolation belt is compared with the outlet position, the clamping part just corresponds to the inlet position of the core cylinder, and when the sleeve at one end of the bending rod moves to the arc plate position of the connecting rod, the pressure plate and the stop rod at the other end of the bending rod move upward under the action of the spring, and will not block the other end of the core column. At this time, the core column automatically slides into the core cylinder under the action of gravity, which is convenient for the cutting blade to perform mid-cutting, and further improves the mid-cutting efficiency of the core column; The core splitting machine can collect water from the cutting blade when the temperature is reduced through the collection shell, which is convenient for centralized storage. The filter plate inside the collection shell can filter the residues in the cutting process. When the water temperature is cooled, the water pump can be started to allow the water inside the collection shell to enter the water storage chamber through the second connecting pipe and the third connecting pipe, which is convenient for recycling. The core splitting machine can be moved by the moving wheels at the bottom of the legs, and the chassis at the bottom can be supported on the ground by rotating the adjusting rod, thereby increasing the stability of the equipment and facilitating adjustment according to the use environment, thereby further improving the flexibility of the equipment itself.

[0009] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0010] See also Figures 1 to 10 The present invention provides a core splitting machine; it includes a frame 1, a top cover 2 and a support leg 3, the top cover 2 is slidably connected in a slideway opened on the top of the frame 1, and the support leg 3 is fixedly connected to the four corners of the bottom of the frame 1.

[0011] like Figure 3 As shown, fastening rings are threadedly connected at the four corners of the top of the frame 1, and the bottom ends thereof extend into the slideway, so as to limit the top cover 2. The top cover 2 is slidably connected to the top of the frame 1, so as to facilitate sealing of the top of the frame 1 and reduce the problem of splashing of water and rock cuttings and dust during the splitting process. At the same time, it is easy to disassemble and facilitate the maintenance of the equipment inside the frame 1 at a later time.

[0012] The supporting leg 3 includes a moving wheel 301 arranged at the bottom thereof, a supporting plate 302 arranged at one side of the moving wheel 301 , an adjusting rod 303 threadedly connected to the upper surface of the supporting plate 302 , and a chassis 304 sleeved on the bottom of the adjusting rod 303 .

[0013] In order to maintain the stability of the equipment, the top of the adjustment rod 303 can be rotated to support the chassis 304 to the ground, which is convenient for improving the stability of the equipment support. When the equipment needs to be moved, the adjustment rod 303 is rotated to raise the chassis 304, and the moving wheel 301 can be used to move it, thereby improving the flexibility of the equipment.

[0014] A partition 4 is provided inside the frame 1, and a driving block 5 is provided in the middle of the back side of the partition 4. The output end of the driving block 5 passes through the partition 4 and is fixedly connected to a cutting blade 6. A core barrel 7 is fixedly connected to the top of the left side of the frame 1. The other end of the core barrel 7 extends to the inside of the frame 1 in an inclined shape and is clamped on the surface of the cutting blade 6. A collecting plate 8 is fixedly connected to the right side wall inside the frame 1 and below the core barrel 7. The collecting plate 8 is connected to an outlet opened at the bottom right side of the frame 1.

[0015] A transmission assembly for conveying core columns is provided at the outlet portion on the right side of the frame 1, a bracket 9 is fixedly connected to the top of the right side of the frame 1, and a bottom end thereof is fixedly connected to the right end of the transmission assembly, a positioning plate 10 is provided on the left side of the frame 1, near the core barrel 7, a material changing assembly for replacing core columns is provided on the surface of the positioning plate 10, and the transmission assembly drives the material changing assembly to rotate along the surface of the positioning plate 10.

[0016] like Figure 3 and Figure 4 As shown, when the core column is placed inside the core barrel 7, the driving block 5 (with an electric motor as the power source) is started to drive the cutting blade 6 to rotate, so as to perform a center cut on the core column. A hollow groove (shown in the figure, not numbered) is provided at one end of the core barrel 7 that penetrates into the frame 1 and is sleeved on the surface of the cutting blade 6. The purpose of such a setting is to facilitate the cutting blade 6 to penetrate into the interior of the core barrel 7 and perform a center cut on the core column inside it; like Figure 1 As shown, a conical cylinder (shown in the figure, not numbered) is provided at the inlet end of the core barrel 7, which can increase the inlet size of the core barrel 7 and facilitate the core column to better enter the interior of the core barrel 7 when sliding downward; the core barrel 7 is fixed to the surface of the frame 1 by bolts, which is convenient for disassembly, assembly and replacement.

[0017] The transmission assembly at the bottom can be supported by the bracket 9 to maintain stability during use. The collecting plate 8 below the core barrel 7 is U-shaped and inclined, which is convenient for the cut core column to slide out from the outlet. A strip groove is provided on the surface of the collecting plate 8. The purpose of this arrangement is to allow the water source of the cutting blade 6 to flow into the inside of the water collecting shell 37 when it is cooled down, thereby reducing the discharge from the outlet. A plurality of sample slots are provided on the upper surface of the support 9 to store different types of sample columns for easy access during detection and analysis.

[0018] A water storage chamber 11 is provided inside the bracket 9, and a connecting pipe 12 connected to the water storage chamber 11 is provided at the bottom of the front side of the bracket 9, and the other end of the connecting pipe 12 extends to the inside of the frame 1, close to the cutting blade 6.

[0019] A stabilizing rod 35 is fixedly connected to the bottom of the frame 1 to increase the stability of the frame 1 during use. An L-shaped rod 36 is fixedly connected to the bottom of the stabilizing rod 35. A water collecting shell 37 is slidably connected inside the L-shaped rod 36. A water pump 38 is provided on the front of the water collecting shell 37. A connecting pipe 2 39 is fixedly connected to the water inlet end of the water pump 38 and a connecting pipe 3 40 is fixedly connected to the water outlet end. A water inlet is provided on the upper surface of the bracket 9 and is connected to the water storage chamber 11. A retaining bar 41 is provided on the inner wall of the water collecting shell 37 and a filter plate 42 is provided above the retaining bar 41.

[0020] like Figure 2 and Figure 3 As shown, a valve is provided on the surface of the connecting pipe 12. When water is injected into the water storage chamber 11 through the water inlet, water can be prevented from being discharged from the other end of the connecting pipe 12. When the core column is cut, the valve is opened. At this time, water flows from the other end of the connecting pipe 12 to the surface of the cutting blade 6 to cool it down and reduce the dust generated when the core column is cut. The waste water generated when the cutting blade 6 is cooled flows along the inner wall of the frame 1 to the inside of the water collecting shell 37 for storage. When larger particles are generated when the core column is cut, they can be filtered through the filter plate 42 to reduce the blockage problem caused by the water pump 38 when pumping water.

[0021] The other end of the connecting pipe 2 39 is fixed to the front side of the water collecting shell 37 and communicated with the interior thereof, and the other end of the connecting pipe 3 40 is fixedly connected to the front side of the bracket 9 and communicated with the water storage chamber 11 .

[0022] When the water source inside the water collecting shell 37 is cooled, the water pump 38 is started, and the water source inside the water collecting shell 37 enters the water storage chamber 11 through the connecting pipe 2 39 and the connecting pipe 3 40, so as to facilitate the recycling of the water source.

[0023] The transmission assembly includes a roller 13 fixedly connected to the right side of the frame 1, a conveyor belt 14 sleeved on the surface of the roller 13, and an isolation belt 15 fixedly connected to the surface of the conveyor belt 14. The right end of the roller 13 is fixedly connected to an auxiliary plate 16, and the bottom end of the side plate of the bracket 9 is fixedly connected to the surface of the auxiliary plate 16. A motor 17 is fixedly connected to one end of the auxiliary plate 16 along the first direction, and the output end of the motor 17 is fixedly connected to the right end of the roller 13.

[0024] like Figure 7 As shown, starting the motor 17 can drive the roller 13 to rotate. Since the conveyor belt 14 is wound around the surface of the roller 13, the two rollers 13 are driven to rotate synchronously. The conveyor belt 14 can be limited by the auxiliary plate 16 to prevent it from falling off the roller 13.

[0025] There are two rollers 13, and a gear rod 18 is fixedly connected to the left end of one of the rollers 13. An auxiliary rod 19 is fixedly connected to the back of the frame 1. The right end of the auxiliary rod 19 extends to the interior of the frame 1, close to the left end of one of the rollers 13, and the left end of the auxiliary rod 19 is fixedly connected to the positioning plate 10.

[0026] One end of the gear rod 18 extends to the interior of the auxiliary rod 19, and the interior of the auxiliary rod 19 is provided with a driving rod 20 meshingly connected to the gear rod 18, the top end of the driving rod 20 is meshingly connected to the driving rod 21, the left end of the driving rod 21 is meshingly connected to the driving rod 3 22, the other end of the driving rod 3 22 is meshingly connected to the driving rod 4 23, the top end of the driving rod 4 23 is meshingly connected to the driving rod 5 24, and the other end of the driving rod 5 24 extends to the interior of the positioning plate 10 and is meshingly connected to the driving rod 6 25.

[0027] like Figure 7 , Figure 8 and Fig. 9As shown, when the drum 13 rotates, the gear rod 18 at its left end rotates synchronously; at both ends of the driving rod 1 20, the driving rod 21, the driving rod 3 22, the driving rod 4 23, the driving rod 5 24 and the driving rod 6 25; each end is provided with a helical gear, and they are meshed and connected with each other, so when the drum 13 rotates, the driving rod 6 25 synchronously drives the gear 29 to rotate, so that the roller 26 drives the fixed belt 27 to rotate; The surface of the roller 26 is provided with teeth, and the surface of the fixed belt 27 is provided with grooves. The teeth and grooves described above are shown in the figure. The purpose of such arrangement is to enable the roller 26 to be meshed and connected with the fixed belt 27, thereby reducing the problem of the roller 26 rotating on its own and not driving the fixed belt 27 to rotate.

[0028] The material replacement assembly includes rollers 26 arranged at the four corners of the positioning plate 10, a fixing belt 27 wrapped around the surface of the roller 26, a clamping clamp arranged on the surface of the fixing belt 27 for supporting the core column, and a connecting rod 28 arranged at the edge of the upper surface of the frame 1 and used in conjunction with the clamping member. A gear 29 is provided on the surface of one of the rollers 26, and the gear 29 is meshed and connected with the right end of the driving rod 6 25.

[0029] The clamping member includes a fixing tube 30 fixedly connected to the surface of the fixing belt 27, a bent rod 31 inserted into the upper surface of the fixing tube 30, a spring 32 and a shift rod 34 which are sleeved on the bent rod 31 and deeply inserted into the fixing tube 30 and on the surface. One end of the bent rod 31 which is deeply inserted into the fixing tube 30 is fixedly connected to a pressing plate 43, and the surface of the other end is sleeved with a sleeve 33. The other end of the shift rod 34 passes through a slideway opened on the inner wall of the fixing tube 30 and extends to the outside.

[0030] like Figure 1 and Figure 6 As shown, the core column that needs to be cut can be placed in advance inside the fixing tube 30. Since the left end of the pressing piece 43 is arranged in an arc shape, when the core column is inserted into the fixing tube 30, the core column can be automatically clamped under the action of the spring 32; since the right end of the stop rod 34 is in a downward L shape, when the core column is inserted into the fixing tube 30, the right end of the stop rod 34 can be used to block the right end of the core column to prevent it from sliding out of the fixing tube 30; The distance that each clamp rotates to the core barrel 7 is equivalent to the distance from point a to point b on the upper surface of the conveyor belt 14 and the isolation belt 15. When point b rotates to the exit position of the frame 1, the next clamp just rotates to the entrance position of the core barrel 7, reducing the manual material replacement action and improving the use efficiency. When the fixing belt 27 rotates along the positioning plate 10 and the fixing cylinder 30 slowly moves toward the inlet position of the core barrel 7, the bending rod 31 uses the sleeve 33 at its right end to rotate along the arc plate position of the connecting rod 28. At this time, the other end of the bending rod 31 is stretched upward by the force of the spring 32. When the bending rod 31 moves to the highest point of the arc plate, the pressing plate 43 inside it no longer clamps the core column, and the right end of the stop rod 34 no longer blocks the right end of the core column. At this time, when the fixing cylinder 30 just rotates to the inlet position of the core barrel 7, the core column automatically slides into the core barrel 7 by its own gravity, so that the core column can be replaced, and at the same time, it is convenient to transport the cut core sample, reduce the mixing of the next core sample, and improve the use efficiency of the equipment.

[0031] The motor 17 mentioned above is a known technology and is only cited here, and the specific structure is not described in detail.

[0032] The electrical components appearing in this article are all connected to an external main controller and 220V~380V mains electricity, and the main controller can be a conventional known device for control such as a computer.

[0033] In the present invention, the working steps of the device are as follows: S1. When in use, the device is moved to a designated position by the moving wheel 301, and the adjusting rod 303 is rotated so that the chassis 304 supports the ground, thereby increasing the stability of the device (a rubber pad (shown in the figure) is provided on the lower surface of the chassis 304 to reduce the vibration problem when the device is in use); S2. Next, insert the core column to be cut into the support part and the interior of the fixing tube 30 in advance, close the valve on the surface of the connecting pipe 12, open the water inlet on the top of the bracket 9, and inject a proper amount of water into the water storage chamber 11. Then, place equipment (e.g., a collection box) for collecting core column samples at the front and rear ends of the conveyor belt 14. S3, start the motor 17, so that the clamping part moves to the inlet position of the core barrel 7 and stops, and with the cooperation of the connecting rod 28, it automatically slides into the interior of the core barrel 7, then start the driving block 5, use the cutting blade 6 to cut the core column in the middle, and open the valve at the same time, so that the water source flows to the position of the cutting blade 6 to cool it and reduce dust on the core column. The cut core column slides from the outlet to the surface of the conveyor belt 14 through the collecting plate 8 by its own gravity, thereby completing the middle cutting of the core column; S4, the waste water cooled by the cutting blade 6 flows to the inside of the water collecting shell 37. When the water temperature inside the water cools down, the water pump 38 is started to pump the waste water to the inside of the water storage chamber 11, which is convenient for recycling and saves water resources; S5. Repeat the above steps.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
