Description

Technical Field

[0001] This utility model relates to the field of coal mining machine technology, and in particular to the cutting auxiliary tool of intelligent deep-well fully mechanized coal mining machine. Background Technology

[0002] A coal mining machine is a piece of equipment used in coal mining, primarily for excavating coal seams in underground mines. It typically consists of several components, including cutting tools, a transmission system, and an electric motor. Coal mining machines can automatically or semi-automatically cut, collect, and transport coal seams, greatly improving the efficiency and safety of coal mining.

[0003] In operation, existing intelligent deep-well fully mechanized coal mining machines collect coal using a cutting head at one end. After collection, the coal is transported via a conveyor belt. During transport, the cutting head is used to crush the coal. During crushing, a certain amount of water is sprayed to reduce dust. Since the coal itself has a high moisture content, some coal tends to stick to the cutting head during crushing, increasing the weight of the cutting head and thus increasing the load on the equipment. Utility Model Content

[0004] The main purpose of this utility model is to provide an auxiliary cutting tool for intelligent deep-well fully mechanized coal mining machines.

[0005] The objective of this utility model can be achieved by adopting the following technical solution: The intelligent deep-well fully mechanized coal mining machine includes a cutting auxiliary tool holder. Multiple cutting blades are equidistantly installed on the outer side of the tool holder. A cleaning component is provided on each cutting blade. The cleaning component includes a support shaft connected to the cutting blade. A bushing is rotatably connected to the outer side of the support shaft. A connecting seat is fixed to the outer side of the bushing. A connecting rod is fixed to one side of the connecting seat. A cleaning block is fixed to one end of the connecting rod.

[0006] Preferably, the cutting blade includes a blade head, a mounting base, and a mounting hole, and the blade head is welded to the mounting base.

[0007] Preferably, the mounting hole is formed on the mounting base, and the mounting base is connected to the tool holder through the mounting hole and bolts.

[0008] Preferably, the tool holder has a connecting groove in the middle, and the connecting groove extends through the tool holder.

[0009] Preferably, the connecting groove has symmetrically formed limiting grooves, and the limiting grooves have a rectangular structure.

[0010] Preferably, the mounting base has a slot, and the support shaft is fixedly connected to the slot and the mounting base.

[0011] The beneficial effects of this technology are: By setting up a cleaning component, when the cutter head drives the cutting blade to rotate and crush the coal, the bushing will drive the connecting seat to rotate the support shaft due to the influence of centrifugal force. During the rotation, the cleaning block will hit the cutting head in the cutting blade through the connecting rod. The vibration generated by the impact can cause the coal adhering to the cutting head to fall off, thereby reducing the weight of the cutting blade and thus reducing the load on the device.

[0014] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0015] like Figures 1-3 As shown, the intelligent deep-well fully mechanized coal mining machine cutting auxiliary tool provided in this embodiment includes a tool holder 1. Multiple sets of cutting blades 2 are equidistantly installed on the outer side of the tool holder 1. A cleaning component 3 is provided on the cutting blade 2. The cleaning component 3 includes a support shaft 301 connected to the cutting blade 2. The support shaft 301 can support the bushing 302. The bushing 302 is rotatably connected to the outer side of the support shaft 301. The bushing 302 can drive the connecting seat 303 to rotate. The connecting seat 303 is fixed to the outer side of the bushing 302. The connecting seat 303 can drive the connecting rod 304 to rotate. The connecting rod 304 is fixed to one side of the connecting seat 303. The connecting rod 304 can drive the cleaning block 305 to impact the cutter head 201. The cleaning block 305 is fixed to one end of the connecting rod 304. When the cleaning block 305 impacts the cutter head 201, it will generate a certain vibration.

[0016] like Figure 1As shown, the cutting blade 2 includes a blade head 201, a mounting base 202, and a mounting hole 203. The blade head 201 is welded to the mounting base 202 to facilitate fixing the blade head 201 to the mounting base 202.

[0017] like Figures 1-2 As shown, mounting holes 203 are formed on mounting base 202, and mounting base 202 and blade holder 1 are connected by mounting holes 203 and bolts, which makes it convenient for workers to use bolts to fix the cutting blade 2 on the blade holder 1 through the mounting holes 203 on mounting base 202, thereby making it convenient for blade holder 1 to drive the cutting blade 2 to rotate.

[0018] like Figures 1-2 As shown, a connecting groove 4 is provided in the middle of the tool holder 1, and the connecting groove 4 passes through the tool holder 1, so that the tool holder 1 can be connected to the external drive shaft through the connecting groove 4.

[0019] like Figures 1-2 As shown, symmetrical limiting grooves 5 are provided on the connecting groove 4, and the limiting grooves 5 have a rectangular structure, which can be adapted to the limiting block of the drive shaft during the installation process.

[0020] like Figures 1-2 As shown, a slot 6 is provided on the mounting base 202, and the support shaft 301 is fixedly connected to the slot 6 and the mounting base 202, so that the bushing 302, the connecting seat 303 and the connecting rod 304 can rotate in the support shaft 301 in the slot 6.

[0021] The working principle of this device is as follows: In actual use, the cutter holder 1 is connected to the external drive shaft through the connecting groove 4. During the connection process, the limiting groove 5 is adapted to the limiting block of the drive shaft. After the connection is completed, the cutter holder 1 is fixed on the drive shaft, and the drive shaft drives the cutter holder 1 to rotate. The operator uses bolts to fix the cutting blade 2 on the cutter holder 1 through the mounting holes 203 on the mounting base 202, so that the cutter holder 1 can drive the cutting blade 2 to rotate. During the rotation, the cutter head 201 crushes the coal. At the same time, due to the influence of centrifugal force, the bushing 302 will drive the connecting base 303 to drive the support shaft 301 to rotate. During the rotation, the connecting rod 304 will drive the cleaning block 305 to impact the cutter head 201 in the cutting blade 2. The vibration generated by the impact can make the coal adhering to the cutter head 201 fall off, thereby reducing the weight of the cutting blade 2 and thus reducing the load of the device.

[0022] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
