Description

Technical Field

[0001] The utility model relates to the technical field of crawler beams, in particular to a crawler beam for a mining machinery crushing and screening machine. Background Art

[0002] The track beam of a crushing and screening machine refers to a structural component used to support and support the crawler system of a mining machinery (such as a crushing and screening machine). It is usually made of a strong metal material and is designed to bear the weight and load of the equipment during operation, while ensuring the stability and mobility of the equipment. Publication No. CN205225250U discloses a track beam of a mining machinery crushing and screening machine, including a main beam body (1), one end of the main beam body (1) is fixed with a sealing plate (2), a hydraulic motor mounting shaft hole (3) is fixed on the sealing plate, a plurality of sprocket mounting seats (4) are fixed on the top of the main beam body, a plurality of supporting wheel mounting holes (5) are opened on the bottom surface of the main beam body, and a wear-resistant protective chain plate (6) is fixed on the lower edge of the main beam body. However, this type of crawler beam is used in a mining environment, and a lot of dust and particulate matter are flying in the working environment. The accumulation of these impurities may affect the normal operation of the crawler beam, which will affect the traction and stability of the crawler. The accumulation of impurities may also cause the crawler to slip or wear unevenly, affecting the operating performance and production efficiency. The cleaning and maintenance of the crawler beam becomes more difficult, requiring additional time and labor to remove dust and perform necessary maintenance, which increases operating and maintenance costs, so it needs to be improved.

The exhaust end of the exhaust fan 10 is connected to the collection chamber 12 through a pipe 11. The exhaust end of the exhaust fan 10 is provided with a pipe 11. Start the exhaust fan 10 and suck out the air inside the mounting plate 4 through the pipe 11, connecting pipe A13, connecting pipe B14 and suction head 8, so that dust impurities and particles can be sucked into the inner side of the collection chamber 12 through the suction head 8, connecting pipe A13, connecting pipe B14. The collection chamber 12 is fixedly installed on the surface of the mounting plate 4, one end of the suction head 8 is connected to the connecting pipe A13, the side of the collection chamber 12 is connected to the connecting pipe B14, and a dust collecting plate 15 is provided on the inner side of the collection chamber 12.

[0027] Example 2

[0028] See also Figure 4-7, a slot 16 is provided at the bottom end of the mounting plate 4, a limiting slot 17 is provided on the inner side of the mounting plate 4, a block 18 is slidably connected to the inner side of the limiting slot 17, a spring 19 is provided on the inner side of the limiting slot 17, one end of the spring 19 is fixedly installed on the inner side of the mounting plate 4, and the other end of the spring 19 is fixedly installed on the side of the block 18, a top plate 20 is slidably connected to the inner side of the suction head 8, a T-shaped connecting block 21 is provided on the surface of the connecting tube A13, a T-shaped connecting slot 22 is provided on the inner side of the connecting tube B14, a threaded sleeve 23 is threadedly connected to the surface of the connecting tube A13, and the connecting tube The surfaces of A13 and the connecting tube B14 are both provided with threads, and the threads on the inner side of the threaded sleeve 23 are engaged with the threads on the surfaces of the connecting tubes A13 and B14, so that the suction head 8 can be quickly disassembled and assembled, and the suction head 8 can be quickly maintained to prevent the suction head 8 from being clogged with internal dust after being used for too long and affecting the dust collection effect. The suction head 8 is adjusted to a position and pushed upward along the mounting plate 4. At this time, the suction head 8 will first come into contact with the block 18, and under the action of pressure and the inclined surface, the block 18 will be driven to shrink along the limit groove 17 and squeeze the spring 19.

[0029] Working principle: When working, first install the crawler on the crawler beam body 1, then align the slot 5 of the mounting plate 4 with the connecting plate 3 and slide it in. After insertion, rotate the limit plate 7 and make it rest against the surface of the connecting plate 3. Then, during the operation of the crushing and screening machine, the crawler will be driven to rotate along the crawler beam body 1. When the crawler passes through the brush plate 6, the dust and particles carried on the inside of the crawler will be brushed off by the brush plate 6, and then fall to the inside of the mounting plate 4 under the action of gravity, and then the exhaust will be started. The machine 10 sucks out the air inside the mounting plate 4 through the pipe 11, the connecting pipe A13, the connecting pipe B14 and the suction head 8, so that dust impurities and particles can be sucked into the inner side of the collection chamber 12 through the suction head 8, the connecting pipe A13 and the connecting pipe B14, and stay on the inner side of the dust collecting plate 15, which improves the working environment while ensuring the normal operation of the crawler beam body 1 and avoids affecting the traction and stability of the crawler. When the suction head 8 needs to be maintained, first turn the threaded sleeve 23 and tighten it on the threaded sleeve. Under the action of the screw sleeve 23, the threaded sleeve 23 is no longer against the connection between the connecting pipe A13 and the connecting pipe B14. Then, the top plate 20 is pushed outward and the block 18 is driven to slide along the limit groove 17 under the action of pressure, and the block 18 is pulled out from the inside of the suction head 8. At this time, under the action of gravity, the suction head 8 will drive the connecting pipe A13 to come out from the inner side of the mounting plate 4 and the slot 16 respectively, so that the maintenance and cleaning of the suction head 8 can be carried out. When installing, first adjust the position of the suction head 8 and push it upward along the mounting plate 4. At this time, The suction head 8 will first come into contact with the block 18, and under the action of pressure and the inclined surface, the block 18 will be driven to shrink along the limit groove 17. As the suction head 8 enters, the block 18 will finally push the top plate 20 under the action of the spring 19 and reset inside the suction head 8. During this process, the T-shaped connecting block 21 will be driven to slide along the T-shaped connecting groove 22. Then, the threaded sleeve 23 is rotated in the opposite direction and, under the action of the thread, it will be pressed against the connection between the connecting pipe A13 and the connecting pipe B14 again. At this time, the fixed installation of the suction head 8 is completed.
