Technical Field
[0001] The invention relates to the technical field of tunnel boring machine equipment, and in particular to a tunnel boring machine capable of simultaneously reducing surrounding pollution. Background Art
[0002] A roadheader is a machine used to dig tunnels on straight ground. There are many types of roadheaders: according to the operating object, they are divided into ordinary machines and tunnel boring machines; according to the operating method, they are divided into open roadheaders and shield roadheaders. They are mainly composed of a traveling mechanism, a working mechanism, a loading mechanism and a transfer mechanism. The current mining roadheader drill bits are prone to generate coal dust during construction, which poses a great threat to operating workers.
[0003] For example, a mining tunneling machine with a dustproof device, whose publication number is CN215057337U, has the following technical solutions: it includes a machine body, a first telescopic column, a second telescopic column, a rotating machine, a drill bit, a spring telescopic sleeve, a rubber surrounding edge, a drill nail, a hydraulic support rod, a water spray head, a first push rod, a push block, and a second push rod. The utility model adjusts the drill bit to a suitable position for mining work through the first telescopic column, the second telescopic column and the hydraulic support rod. When the drill bit is mining, the spring telescopic sleeve is compressed, and the rubber surrounding edge is attached to the outside of the mining position of the drill bit to form a closed space to prevent the dust generated during the work from spreading out. The water spray head is used to spray the coal ash at the mining position. The water mist dust reduction treatment further improves the dust reduction effect. The push block fixedly connected to the first push rod and the second push rod can push the mined coal seam to both sides of the machine through the driving device, effectively reducing the resistance encountered when the device moves forward, and further improving the working efficiency of the device. However, when the device is removing dust, it is necessary to press the spring telescopic sleeve against the drill hole. When used in a tunnel boring machine with multiple drill bits, it is difficult to completely seal the drill hole, so that dust will still escape to the surroundings, causing pollution to the surrounding environment. Moreover, when the tunnel boring machine completes drilling and moves away, the spring telescopic sleeve is detached from the drill hole, and incomplete dust cleaning may still occur, which reduces the dust reduction effect of the device and has defects when used.

[0032] 1. A collection component is provided. When the main body of the tunnel boring machine is in use, the motor is started, and the motor drives the rotating shaft and the fan blades to rotate. The fan blades extract air from the dust collecting pipe and the inside of the conical cylinder, and then extract the dust from the outside of the main body of the tunnel boring machine.

The rotation of the slave bevel gears drives the arc plate to rotate. The arc plate is similar to a cam and can intermittently squeeze the connecting block. When squeezing, the sliding rod is first compressed, and the sliding rod drives the fixed plate to move. The fixed plate stretches the spring three, and the fixed plate breaks up the water mist sprayed from the nozzle, thereby increasing the spray angle and spray range and improving the dust reduction effect. At the same time, when squeezing the connecting block, the arc plate will drive the connecting block to move.

[0057] Embodiment 1: Figure 1-6 and Figure 8-9As shown, a collecting component 6 is provided. When the tunnel boring machine body 1 is in use, the motor 61 is started, and the motor 61 drives the rotating shaft 62 and the fan blades 64 to rotate. The fan blades 64 exhaust air from the dust collecting pipe 2 and the inside of the conical tube 8, and then extract the dust on the outside of the tunnel boring machine body 1. After the dust and gas are guided by the guide block 11, the flow rate becomes larger, thereby improving the dust collection effect. At the same time, the rotating shaft 62 drives the main gear 65 to rotate, and the main gear 65 drives multiple slave gears 69 to rotate, and the slave gears 69 only rotate on their own.
[0058] And the diameter of the slave gear 69 is larger than that of the main gear 65, so that the slave gear 69 drives the inner ring 67 to rotate slowly, and the inner ring 67 drives the connecting rod 610 and the rotating member 611 to rotate, and the rotating member 611 drives the scraper rod 612 to rotate, and the scraper rod 612 assists in scraping the air inlet surface of the filter plate 12, and when the scraper rod 612 rotates to the position of the blocking rod 616, the scraper rod 612 is squeezed and swung by the blocking rod 616, and the scraper rod 612 cooperates with the fixed block 613 to compress the spring 1 614, so that the dust accumulated on the scraper rod 612 will be scraped by the blocking rod 616 and collected in the sundries box 4, thereby reducing the adhesion of dust on the scraper rod 612, and also reducing the blockage of the filter plate 12, thereby improving the dust collection efficiency and reducing the escape of dust.
[0059] A spray assembly 7 is provided on one side of the dust collecting pipe 2 near the collecting box 3, and the spray assembly 7 includes symmetrically arranged mounting blocks 71, the inner sides of the two mounting blocks 71 are fixedly connected with sliding rods 72, the outer sides of the sliding rods 72 are slidably connected with mounting rings 73, the outer sides of the sliding rods 72 are sleeved with springs 74, the outer sides of the rotating shaft 62 are fixedly connected with main bevel gears 75, and the inner wall of the dust collecting pipe 2 is symmetrically installed with slave bevel gears 76.
[0060] The mounting ring 73 is located at the inner side of the two mounting blocks 71 , the second spring 74 is slidably connected to the slide bar 72 , one end of the second spring 74 is fixedly connected to the mounting block 71 , and the other end of the second spring 74 is fixedly connected to the mounting ring 73 .
[0061] The slave bevel gear 76 is meshed with the main bevel gear 75 , an arc plate 77 is fixedly connected to one side of the slave bevel gear 76 , a connecting block 78 is fixedly connected to one side of the mounting ring 73 close to the slave bevel gear 76 , and a nozzle 712 is installed inside the mounting ring 73 .
[0062] The main bevel gear 75 is located on one side of the mounting ring 73 close to the motor 61 , the slave bevel gear 76 is rotationally connected to the dust collecting pipe 2 , the arc plate 77 is in contact with the connecting block 78 , and a sliding rod 79 is connected to the interior of the connecting block 78 .

[0065] Embodiment 2: Figure 7 and Figure 10-11 As shown, a spray assembly 7 is provided, and the pressure pump 10 is started. The pressure pump 10 draws water from the water tank 9 and sprays it through the nozzle 712 inside the mounting ring 73. The rotation of the rotating shaft 62 will also drive the main bevel gear 75 to rotate. The main bevel gear 75 drives the slave bevel gears 76 on both sides to rotate. The rotation of the slave bevel gears 76 drives the arc plate 77 to rotate. The arc plate 77 is similar to a cam and can intermittently squeeze the connecting block 78. When squeezing, the sliding rod 79 is first compressed. The sliding rod 79 drives the fixed plate 710 to move. The fixed plate 710 stretches the spring three 711.

In addition, when the tunnel boring machine is completed and moved away, there may still be incomplete dust cleaning, which reduces the dust reduction effect of the device.
[0067] Working principle: When using the device, first, Figure 1-11 As shown, when the tunnel boring machine body 1 is in use, the motor 61 is started, and the motor 61 drives the rotating shaft 62 and the fan blades 64 to rotate. The fan blades 64 exhaust air from the dust collecting pipe 2 and the conical tube 8, and then extract the dust from the outside of the tunnel boring machine body 1. After the dust and gas are guided by the guide block 11, the flow velocity becomes larger, thereby improving the dust collection effect.
[0068] At the same time, the rotating shaft 62 drives the main gear 65 to rotate, and the main gear 65 drives multiple slave gears 69 to rotate. The slave gear 69 only rotates on its own, and the diameter of the slave gear 69 is larger than the main gear 65, so that the slave gear 69 drives the inner ring 67 to rotate slowly, and the inner ring 67 drives the connecting rod 610 and the rotating member 611 to rotate, and the rotating member 611 drives the scraping rod 612 to rotate, and the scraping rod 612 assists in scraping the air inlet surface of the filter plate 12.
[0069] When the scraper rod 612 rotates to the position of the blocking rod 616, the scraper rod 612 is squeezed and swung by the blocking rod 616, and the scraper rod 612 cooperates with the fixing block 613 to compress the spring 1 614, so that the dust accumulated on the scraper rod 612 is scraped off by the blocking rod 616 and collected in the sundries box 4.
[0070] Start the pressure pump 10, which draws water from the water tank 9 and sprays it through the nozzle 712 inside the mounting ring 73. The rotation of the rotating shaft 62 will also drive the main bevel gear 75 to rotate, and the main bevel gear 75 drives the slave bevel gears 76 on both sides to rotate. The rotation of the slave bevel gears 76 drives the arc plate 77 to rotate. The arc plate 77 is similar to a cam and can intermittently squeeze the connecting block 78. When squeezing, the sliding rod 79 is first compressed, and the sliding rod 79 drives the fixed plate 710 to move. The fixed plate 710 stretches the spring three 711, and the fixed plate 710 breaks up the water mist sprayed from the nozzle 712, thereby increasing the spraying angle and spraying range, and improving the dust reduction effect.
[0071] When the arc plate 77 squeezes the connecting block 78, it will drive the connecting block 78 to move, and the connecting block 78 will drive the mounting ring 73 to slide on the slide rod 72. The spring 2 74 is used to reset the mounting ring 73, so as to facilitate the linear reciprocating movement of the mounting ring 73, further improving the spraying range and having a better dust reduction effect on the extracted flue gas. The water after spraying falls into the reflux box 5 for collection, and the gas after spraying is input into the collection box 3 for collection.
