[0034] As Figure 1 、 Figure 2 and Figure 3 shown, the embodiment of this application provides a core cutter, which includes a support mechanism 100, a cutting mechanism 200, a pushing mechanism 300 and a cooling mechanism 400; wherein, the support mechanism 100 includes a workbench plate 110 for supporting the core and a support frame 120 for supporting the workbench plate 110. The support frame 120 includes four support columns 130 whose tops are respectively connected to the four corners of the bottom of the workbench plate 110 and fixing plates 140 respectively connected to two support columns 130. A reinforcing rod 190 is connected between two adjacent support columns 130, and the fixing plate 140 is respectively connected to three reinforcing rods 190. The bottom of each support column 130 is connected with a universal wheel 150. One side of the workbench plate 110 is hinged with a baffle 160. When the baffle 160 rotates to the vertical arrangement, it is located on the side of the belt 270. The bottom of the baffle 160 is connected with a connecting plate 170. When the baffle 160 rotates to the vertical arrangement, the connecting plate 170 rotates to the bottom of a reinforcing rod 190 for detachable connection with bolts.
[0035] The cutting mechanism 200 includes a core barrel 210 detachably connected to the workbench plate 110 by bolts, a cutting saw blade 220 rotatably disposed below the workbench plate 110, and a cutting drive mechanism for driving the cutting saw blade 220 to rotate; the top of the cutting saw blade 220 penetrates through the workbench plate 110 and the bottom wall of the core barrel 210 and extends into the core barrel 210. When the cutting saw blade 220 rotates, it cuts through the core in the core barrel 210; the cutting drive mechanism includes a transmission shaft 230, a cutting motor 240 connected to the fixing plate 140, a belt 270, and two pedestal bearings 280 connected to the bottom of the workbench plate 110. A saw blade 250 is fixedly sleeved on one end of the transmission shaft 230, and a pulley 260 is connected to the other end of the transmission shaft 230. The transmission shaft 230 is a stepped shaft, and locking nuts 231 for fixing the saw blade 250 and the pulley 260 are respectively connected by threads at both ends. Gaskets 232 are also sleeved on the transmission shaft 230 on both sides of the saw blade 250. Both ends of the belt 270 are respectively sleeved on the pulley 260 and the output shaft of the cutting motor 240. The transmission shaft 230 is rotatably connected to the two pedestal bearings 280. A sleeve 233 is sleeved on the transmission shaft 230, and both ends of the sleeve 233 press against the two pedestal bearings 280. The transmission shaft 230 and the sleeve 233 are connected by a pin key; the pulley 260 is fixedly connected to the transmission shaft 230 by a key connection.
[0036] The pushing mechanism 300 is a pushing cylinder, and a pressure sensor 310 is connected to the end of the cylinder rod of the pushing cylinder; when the cylinder rod of the pushing cylinder extends, it drives the core to axially move through the core barrel 210, and the pressure sensor 310 detects the pressure received by the core; wherein the rodless chamber and the rod chamber of the pushing cylinder are respectively connected to two air outlets of a two-position three-way solenoid valve through air pipes, and the air inlet of the two-position three-way solenoid valve is connected to an air pump through an air pipe. By controlling the air pump and the two-position three-way solenoid valve, the extension and retraction of the cylinder rod of the pushing cylinder can be controlled. The pushing cylinder and its supporting facilities are prior arts, so their specific structures will not be described in detail.
[0037] The cooling mechanism 400 includes a recovery tank 410 fixed below the workbench plate 110 and a cooling water pipe 420 with one end penetrating into the core barrel 210. The recovery tank 410 is used to receive water and debris flowing out of the core barrel 210, and a stop valve 430 for connecting or disconnecting the cooling water pipe 420 is provided on the cooling water pipe 420.
[0038] The working principle of the core cutting machine provided by the embodiment of the present application is as follows: Before the core splitting and cutting operation, check whether each mechanism component is safely assembled and working properly. Subsequently, after connecting the water source and the cooling water pipe 420 with a water pump and a water pipe, turn on the water pump and the stop valve 430, so that the cooling water of the water source is introduced into the core pipe 210 through the cooling water pipe 420 by the water pump. Then, insert one end of the core into the core pipe 210, and place the other end at the cylinder rod of the pushing mechanism 300. Turn on the power supply of the cutting motor 240. The output shaft of the cutting motor 240 drives the pulley 260 and the transmission shaft 230 to rotate through the belt 270, and then drives the saw blade 250 to rotate. Control the pushing cylinder piston rod of the pushing mechanism 300 to extend to push the core to move axially through the core pipe 210, so that the top extends into the core pipe 210 after passing through the workbench plate 110 and the bottom wall of the core pipe 210, and the rotating saw blade 250 in the core pipe 210 cuts the core passing through the core pipe 210. During the cutting process, the pressure sensor 310 detects the pressure data of the core in real time. At the same time, the cooling water introduced into the core pipe 210 by the cooling water pipe 420 continuously flushes the contact part between the saw blade 250 and the core, and makes the flushing wastewater and debris flow out of the core pipe 210 and into the recovery tank 410 to be recycled into the wastewater recovery bucket pre-placed at one end. After the core cutting is completed, turn off the cutting motor 240 and the stop valve 430, and control the pushing cylinder piston rod of the pushing mechanism 300 to retract to complete the core cutting operation.
[0039] Wherein, one side of the workbench plate 110 is hinged with a baffle 160. The bottom of the baffle 160 is connected with a connecting plate 170. When the baffle 160 rotates to a vertical arrangement, the connecting plate 170 rotates to the bottom of a reinforcing rod 190 for detachable connection with bolts, so as to facilitate the operator to rotate the baffle 160 to the side of the belt 270 and fix it to protect the belt 270 when needed, and to separate the baffle 160 from the bottom of the reinforcing rod 190 and rotate it up for the operator to repair the cutting mechanism 200 when needed.
[0040] In other alternative embodiments, such as Figure 4 As shown, a core guiding groove 180 for supporting and restricting the axial movement of the core is further provided on the top of the workbench plate 110. The core guiding groove 180 is located between the core pipe 210 and the pushing mechanism 300. The pushing mechanism 300 is used to drive the core guiding groove 180 to support the core to move axially through the core pipe 210. The core guiding groove 180 is a groove body with a semi-circular cross-section.
[0041] In other alternative embodiments, such as Figure 5As shown, the core barrel 210 is threadedly connected with three positioning bolts 290 arranged at intervals along its circumferential direction. When the positioning bolts 290 rotate, they move axially and radially with respect to the core barrel 210 to press against or stop pressing against the core passing through the core barrel 210. By providing the positioning bolts 290 arranged at intervals along the circumferential direction of the core barrel 210 and threadedly connected to the core barrel 210, it is convenient for the operator to rotate the positioning bolts 290 to move them radially with respect to the core barrel 210 to press against or stop pressing against the core passing through the core barrel 210, so as to fix the radial position of the core and ensure that the core stably passes through the core barrel 210 for cutting operations. At the same time, it is also possible to stably cut cores of different specifications and diameters smaller than its inner diameter using the core barrel 210. In other alternative embodiments, the core barrel 210 may also be connected with two or more groups of positioning bolts 290. Each group of positioning bolts 290 is arranged at intervals along the axial direction of the core barrel 210, and each group includes at least one positioning bolt 290 that moves axially and radially with respect to the core barrel 210 to press against or stop pressing against the core passing through the core barrel 210 when rotated.
[0042] In other alternative embodiments, a display screen electrically connected to the pressure sensor 310 may also be provided, so as to display in real time the pressure exerted on the core detected by the pressure sensor 310 through the display screen, thereby helping the operator to judge the core cutting situation. When the core gets stuck, the pressure detected by the pressure sensor 310 will increase significantly. At this time, the operator can turn off the cutting motor 240 to stop cutting and avoid damaging the core by the cutting saw blade 220.
