Description

Technical Field

[0001] This application relates to the field of mining stone cutting machine technology, and in particular to a cooling water cover for a mining saw blade. Background Technology

[0002] In mining operations, the main method is to use a stone cutting machine to cut the ore into movable stone. Currently, when the saw blade is rotating to cut the stone, water needs to be sprayed onto the saw blade to reduce its temperature, thereby ensuring that the saw blade can cut normally.

[0003] Currently, the main method for cooling saw blades is to use water covers. The water covers are fixedly installed on the mining stone cutting machine and cover the saw blade. Multiple nozzles connected to the water covers spray water toward the saw blade to cool it down. At the same time, the water covers can also block the debris generated during cutting to prevent debris from flying and causing safety hazards.

[0004] Regarding the aforementioned technologies, the water cover is generally fixed to the main body of the mining stone cutting machine with bolts. When the saw blade needs to be repaired or replaced regularly, the water cover, being close to the saw blade, usually needs to be disassembled simultaneously, which is inconvenient and affects the work efficiency. Utility Model Content

[0005] To address the inconvenience and reduced work efficiency caused by the need for simultaneous disassembly of the water cover when the saw blade requires regular maintenance or replacement, this application provides a cooling water cover for mining saw blades.

[0006] The technical solution for a cooling water cover for mining saw blades provided in this application is as follows:

[0007] A cooling water cover for a mining saw blade includes a stone cutting machine body, a main shaft, a saw blade, a mounting plate, a left side plate, a top plate, and a right side plate. The main shaft is rotatably connected to the stone cutting machine body, and the saw blade is mounted on the main shaft. The mounting plate is vertically mounted on the stone cutting machine body, and the left side plate is slidably connected to the mounting plate vertically. The left side plate has a front side plate and a rear side plate on its front and rear sides, respectively. The mounting plate has a first driving mechanism for driving the left side plate to slide. One end of the top plate is rotatably connected to the mounting plate, and a water supply pipe is provided at the bottom of the top plate. The water supply pipe has multiple nozzles, and the mounting plate has a second driving mechanism for driving the top plate to rotate. The right side plate is rotatably connected to one end of the top plate, and the top plate has a third driving mechanism for driving the right side plate to rotate.

[0008] By adopting the above technical solution, the main body of the stone cutting machine provides overall support. The rotation of the main shaft drives the saw blade to rotate, thereby cutting the ore. The saw blade is located within the space enclosed by the left side plate, front side plate, rear side plate, top plate, and right side plate, which isolates the flying debris caused by the rotation of the saw blade. The water supply pipe and nozzle spray water towards the saw blade, thereby cooling the saw blade and reducing dust. When the saw blade needs to be replaced, the first drive mechanism drives the left side plate to rise and no longer obstructs the saw blade. At the same time, the second drive mechanism drives the top plate to flip upward, and the third drive mechanism drives the right side plate to flip upward as well, without obstructing the maintenance or replacement of the saw blade. This facilitates the maintenance or replacement of the saw blade and improves the problem that when the saw blade needs to be regularly maintained or replaced, the water cover usually needs to be disassembled at the same time, which is inconvenient and affects the work efficiency. In addition, the upward flipping of the top plate and right side plate also exposes the water supply pipe and nozzle, making maintenance and replacement easier and ensuring the cooling effect on the saw blade.

[0009] Optionally, the first drive mechanism includes a lead screw, a lifting plate, and a first rotating motor. The lead screw is rotatably connected to the mounting plate about a vertical direction. The lead screw passes through the lifting plate and is threadedly connected to the lifting plate. The left side plate is connected to the lifting plate. The first rotating motor is mounted on the mounting plate, and the rotating shaft of the first rotating motor is connected to the lead screw.

[0010] By adopting the above technical solution, the first rotating motor is started to drive the lead screw to rotate, thereby driving the lifting plate to rise and fall vertically, and then driving the left side plate to rise and fall. The lifting and falling of the left side plate is achieved through threaded connection, making the lifting and falling more stable and reliable.

[0011] Optionally, the second drive mechanism includes a gear and a rack. The top plate is rotatably connected to the mounting plate via a first rotating pin. The gear is coaxially connected to the first rotating pin. The rack is vertically mounted on the lifting plate. The gear and rack mesh.

[0012] By adopting the above technical solution, the lifting plate drives the rack to rise and fall during the lifting process. Since the rack meshes with the gear, it drives the gear to rotate in both directions, which in turn drives the first rotating pin to rotate in both directions, thereby driving the top plate to rotate. No additional power source is required, saving costs.

[0013] Optionally, the third drive mechanism includes a worm gear, a worm, and a second rotating motor. The right side plate is rotatably connected to the top plate via a second rotating pin. The worm gear is coaxially connected to the second rotating pin. The second rotating motor is mounted on the top plate. The worm is mounted on the rotating shaft of the second rotating motor. The worm gear meshes with the worm.

[0014] By adopting the above technical solution, starting the second rotating motor drives the worm to rotate, which in turn drives the worm wheel to rotate, thereby driving the second rotating pin to rotate, thus realizing the rotation of the right side plate. The worm gear transmission has self-locking properties, which makes the rotation of the right side plate more accurate and reliable.

[0015] Optionally, the front side plate has a transverse insertion hole, a locking rod is inserted into the insertion hole, a return spring is sleeved on the locking rod, one end of the return spring is connected to the locking rod, and the other end of the return spring is connected to the front side plate. The right side plate has a positioning hole corresponding to the locking rod, and the locking rod is inserted into the positioning hole when the return spring tends to align the insertion hole with the positioning hole.

[0016] By adopting the above technical solution, when the insertion hole and the positioning hole are aligned, the return spring can cause the locking rod to be inserted into the positioning hole, thereby locking the front side plate and the right side plate, thus enhancing the stability of the cooling water cover structure of the mining saw blade.

[0017] Optionally, the mounting plate has multiple waist-shaped grooves, and the main body of the stone cutting machine is fixedly connected to each waist-shaped groove. The limiting post passes through the waist-shaped groove and is threaded with a positioning nut.

[0018] By adopting the above technical solution, a waist-shaped groove is opened on the mounting plate, and the limiting post on the main body of the stone cutter passes through the waist-shaped groove and is fixed by the positioning nut. This allows for the adjustment and positioning of the mounting plate on the main body of the stone cutter, making it convenient to adjust the installation position of the cooling water cover of the mining saw blade according to actual needs.

[0019] Optionally, the left side plate, top plate, right side plate, front side plate, and rear side plate are all provided with buffer pads on the side near the saw blade.

[0020] By adopting the above technical solution, buffer pads are installed on the side of the left side plate, top plate, right side plate, front side plate and rear side plate near the saw blade, which can play a buffering role, reduce the damage of the debris brought up by the saw blade during operation to each side plate, and extend its service life.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The first drive mechanism drives the left side plate to slide vertically, the second drive mechanism drives the top plate to rotate, and the third drive mechanism drives the right side plate to rotate, thereby realizing the enclosure and removal of the saw blade, which facilitates the repair or replacement of the saw blade. This improves the problem that when the saw blade needs to be repaired or replaced regularly, the water cover usually needs to be disassembled at the same time, which is inconvenient and affects the work efficiency.

[0023] 2. The screw, lifting plate, and first rotating motor are designed to enable the lifting of the left side plate via a threaded connection, making the lifting of the left side plate more stable and reliable.

[0024] 3. The gear and rack configuration allows the lifting plate to move up and down, driving the rack to rotate in both directions simultaneously, thus driving the top plate to rotate in both directions. No additional power source is required, saving costs. Attached Figure Description

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses a cooling water cover for a mining saw blade 2. (Refer to...) Figure 1-2 The cooling water cover for the mining saw blade 2 includes a stone cutting machine body 1, a main shaft 11, a saw blade 2, a mounting plate 3, a left side plate 4, a top plate 5, and a right side plate 6. The main shaft 11 is rotatably connected to the stone cutting machine body 1 and can rotate at high speed under the drive of a motor within the body 1. The saw blade 2 is coaxially mounted on the main shaft 11. A groove is formed on the inner wall of the saw blade 2, and a positioning key is embedded in the main shaft 11, which is also engaged in the groove. Fastening nuts are threaded onto both sides of the main shaft 11, thus facilitating the installation of the saw blade 2.

[0032] The mounting plate 3 has a vertically shaped groove 31 along its upper edge. Multiple grooves are provided. A limiting post 12 is welded and fixed to the right side wall of the stone cutting machine body 1 corresponding to each groove 31. The limiting post 12 passes through each groove 31 and is threaded with a positioning nut 13. The positioning nut 13 presses against the mounting plate 3, thus fixing the mounting plate 3 to the stone cutting machine body 1. The design of the groove 31 allows the mounting plate 3 to be adjusted vertically to a certain extent. The left side plate 4 is vertically slidably connected to the mounting plate 3. The saw blade 2 is located on the right side of the left side plate 4. A front side plate 41 and a rear side plate 42 are vertically welded to the front and rear sides of the left side plate 4, respectively. The mounting plate 3 is equipped with a first driving mechanism for driving the left side plate 4 to slide. The top plate 5 is rotatably connected to the mounting plate 3 at its left end. A water supply pipe 51 is installed at the bottom of the top plate 5, which is connected to an external water source. Multiple nozzles 52 are installed on the water supply pipe 51, and the spray direction of the nozzles 52 is towards the saw blade 2. The mounting plate 3 is provided with a second drive mechanism for driving the top plate 5 to rotate. The right side plate 6 is rotatably connected to the right end of the top plate 5. The top plate 5 is provided with a third drive mechanism for driving the right side plate 6 to rotate. The saw blade 2 is located within the space enclosed by the left side plate 4, the front side plate 41, the rear side plate 42, the top plate 5, and the right side plate 6.

[0033] In operation, the spindle 11 rotates, driving the saw blade 2 to cut the ore. The saw blade 2 is located within the space enclosed by the left side plate 4, front side plate 41, rear side plate 42, top plate 5, and right side plate 6, thus isolating the flying debris caused by the rotation of the saw blade 2. The water supply pipe 51 and the nozzle 52 spray water towards the saw blade 2, cooling it and reducing dust. When the saw blade 2 needs to be replaced, the first drive mechanism drives the left side plate 4 to rise, no longer obstructing the saw blade 2. At the same time, the second drive mechanism drives the top plate 5 to flip upward, and the third drive mechanism drives the right side plate 6 to flip upward as well, without hindering the maintenance or replacement of the saw blade 2. This facilitates the maintenance or replacement of the saw blade 2, improving the problem that when the saw blade 2 needs regular maintenance or replacement, the water cover usually needs to be disassembled simultaneously, which is inconvenient and affects work efficiency. In addition, the upward flipping of the top plate 5 and the right side plate 6 also exposes the water supply pipe 51 and the nozzle 52, making maintenance and replacement easier and ensuring the cooling effect on the saw blade 2.

[0034] In addition, refer to Figure 2 To reduce damage to the side plates caused by flying debris during the rotary cutting process of the saw blade 2, buffer pads 7 are installed on the side of the left side plate 4, top plate 5, right side plate 6, front side plate 41, and rear side plate 42 near the saw blade 2. The buffer pads 7 are made of elastic materials such as rubber, and their function is to reduce the wear of flying debris on the side plates themselves during the cutting process and extend their service life.

[0035] For example, refer to Figure 1The first driving mechanism includes a lead screw 32, a lifting plate 33, and a first rotary motor 34. The lead screw 32 is rotatably connected to the mounting plate 3, passes through the lifting plate 33, and is threadedly connected to it. The left side wall of the lifting plate 33 abuts against the mounting plate 3, and the right side of the lifting plate 33 is welded to the left side plate 4. The first rotary motor 34 is bolted to the bottom of the mounting plate 3, and its rotating shaft is connected to the lead screw 32. Starting the first rotary motor 34 drives the lead screw 32 to rotate, which in turn drives the lifting plate 33 to slide vertically, thereby raising and lowering the left side plate 4. The movement of the left side plate 4 is smooth and reliable.

[0036] For example, refer to Figure 2 and Figure 3 The second drive mechanism includes a gear 35 and a rack 36. The rack 36 is vertically welded and fixed to the lifting plate 33. A connecting rod is connected to the left end of the top plate 5. A first rotating pin 37 is horizontally fixedly inserted into the connecting rod. The first rotating pin 37 is rotatably connected to the mounting plate 3. The gear 35 is coaxially connected to the first rotating pin 37, and the gear 35 and the rack 36 mesh with each other. During the lifting process, the lifting plate 33 drives the rack 36 to rise and fall, thereby driving the gear 35 meshing with the rack 36 to rotate, which in turn drives the first rotating pin 37 to rotate and cause the top plate 5 to flip. No additional power source is required, saving power costs.

[0037] Specifically, refer to Figure 1 The third drive mechanism includes a worm gear 53, a worm 54, and a second rotary motor 55. A second rotating pin 56 is fixedly inserted laterally into the top of the right side plate 6, and the second rotating pin 56 is rotatably connected to the right end of the top plate 5. The second rotary motor 55 is fixedly installed on the top of the top plate 5. The worm 54 is coaxially connected to the rotating shaft of the second rotary motor 55, and the worm gear 53 is coaxially connected to the second rotating pin 56, with the worm gear 53 meshing with the worm 54. Starting the second rotary motor 55 drives the worm 54 to rotate, which in turn drives the worm gear 53 and the second rotating pin 56 coaxially connected to it to rotate, thereby causing the right side plate 6 to flip up and down. The worm gear 53 and worm 54 transmission has self-locking properties, making the rotation of the right side plate 6 more precise and reliable.

[0038] Furthermore, since the saw blade 2 generates significant vibration during high-speed rotation and cutting of ore, in order to ensure the stability of the installation of each side plate and thus protect the saw blade 2, a transverse insertion hole is provided on the front side plate 41, and a locking rod 411 is inserted into the insertion hole. A return spring 412 is fitted on the locking rod 411, with one end of the return spring 412 connected to the locking rod 411 and the other end connected to the front side plate 41. A positioning hole is provided on the front side wall of the right side plate 6 corresponding to the locking rod 411. When the return spring 412 tends to align the insertion hole with the positioning hole, the locking rod 411 is inserted into the positioning hole. When the right side plate 6 is in a vertical position, the positioning hole on the right side plate 6 is aligned with the insertion hole of the front side plate 41. Under the elastic force of the return spring 412, the locking rod 411 passes through the insertion hole and is inserted into the positioning hole on the right side plate 6, thereby achieving a fixed connection between the front side plate 41 and the right side plate 6. This makes each side plate and the top form a stable whole, ensuring the protection effect of the saw blade 2 and preventing the flying of chips during the cutting process of the saw blade 2.

[0039] The implementation principle of the cooling water cover for the mining saw blade 2 in this embodiment is as follows: When the saw blade 2 is cutting, each side plate and the top plate 5 form a stable whole surrounding the saw blade 2, thereby isolating the flying debris caused by the rotation of the saw blade 2. The water pipe 51 and the nozzle 52 on the top plate 5 spray water towards the saw blade 2 to cool the saw blade 2 and reduce dust. When it is necessary to repair or replace the saw blade 2 and the nozzle 52, the first rotating motor 34 is started to drive the lead screw 32 to rotate, thereby driving the lifting plate 33 to rise, driving the left side plate 4 to rise and no longer block the saw blade 2. At the same time, during the rising process, the lifting plate 33 drives the rack 36 to rise, thereby synchronously driving the gear 35 to rotate, driving the first rotating pin 37 to rotate, thereby driving the top plate 5 to flip up. Next, the second rotating motor 55 is started to drive the worm gear 54 to rotate, which in turn drives the worm wheel 53 to rotate, thereby driving the second rotating pin 56 to rotate, realizing the upward flipping of the right side plate 6, thus exposing the saw blade 2 and the nozzle 52, which is convenient for maintenance and replacement. This improves the problem that when the saw blade 2 needs to be maintained or replaced regularly, the water cover is close to the saw blade 2 and usually needs to be disassembled at the same time, which is inconvenient for disassembly and assembly and affects the work efficiency.

[0040] The above are all optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
