Description
Technical Field
[0001] The utility model belongs to the technical field of dust collection for rock drilling rigs, in particular to a dust collector for rock drilling rigs. Background Art
[0002] A rock drill is a mechanical device used to drill holes in brittle materials such as rock or concrete. A dust collector is a device that collects suspended dust and mist from the gas. It is typically installed between the rock drill's jet disc and the jet dust collection pipe. The dust collector's suction pipe is typically connected to the rock drill at or near the machine's outlet. To more effectively collect dust, the suction pipe needs to fit snugly against the rock drill's outlet.
[0003] Existing dust collectors include: a shell, a filter element, a blower, a dust outlet, etc. The blower sucks dust from the outside of the shell into the shell, and then discharges it outward after being filtered by the filter element, thereby reducing the pollution intensity of the dust generated during operation to the air.
[0004] However, there are still some problems with the dust collector of rock drilling rigs. Generally, the drilling rig has a large amount of work and a long working time. If the filter element in the dust collector is disassembled and cleaned, the disassembly frequency is frequent and the workload is large. As a result, after the filter element is used for a long time, the gas filtering effect is reduced. Therefore, a dust collector for rock drilling rigs is proposed to address the above problems.

[0008] Preferably, a box door is provided on the front side of the shell, a second limiting groove is symmetrically opened inside the shell, a dust collecting box is provided inside the box door, and second limiting blocks are fixedly connected to both sides of the dust collecting box. After the dust collector is finished running, the box door is opened and the dust collecting box is pulled outward to clean the cleaning water and dust debris that fall into the dust collecting box during cleaning.
[0009] Preferably, the second limit block is slidably connected to the inside of the second limit groove, a dust suction tube is fixedly connected to one side of the shell, one end of the dust suction tube is fixedly connected to a rubber ring, a reinforcement ring is provided on the outside of the rubber ring, and the rubber ring is sleeved on one end of the pipe next to the drill bit of the rock drilling rig, thereby increasing the friction with the rock drilling rig and improving the tightness of the connection between the two.

[0011] Preferably, one end of the bolt is threadedly connected to the inside of the fixing nut, and one end of the bolt is fixedly connected to a limiting plate. The limiting plate is located on one side of the reinforcement ring. The bolt, nut and limiting plate cooperate to reduce the size of the reinforcement ring opening, thereby reducing the circle dimension of the reinforcement ring and improving the tightness of the connection between the vacuum tube and the rock drilling rig.
[0012] The benefits of the present invention lie in that a cleaning assembly is provided inside the dust collector and is located outside the filter element. The position of the hollow connecting ring is adjusted by rotating the screw rod, so that the hollow connecting ring can move back and forth outside the filter element, thereby allowing clean water to flow to the surface of the filter element.

[0023] The connection position between the dust collection pipe 19 of the dust collector and the rock drilling rig is usually at or near the outlet of the machine. Generally, the drilling rig has a large amount of work, and the filter element contains a lot of dust, so the filter element needs to be cleaned to ensure the filtering effect of the filter element. In actual use, the water pump 10 is started to pump the clean water in the water tank 11 into the hollow connecting ring 12, and the water flows to the surface of the filter element through the water outlet 14. Then the drive motor 4 is started to drive the screw rod 5 to rotate. Because the internal thread of the adjusting block 6 matches the thread on the surface of the screw rod 5, the position of the adjusting block 6 and the connecting block 7 is adjusted when the screw rod 5 rotates, and then the transmission pipe 9 is driven to move synchronously through the connecting block 7. Because the upper part of the transmission pipe 9 is a hose, which is connected to the connecting block 7 and the lower end is a hard pipe, when the connecting block 7 moves, the hollow connecting ring 12 is driven to move synchronously through the transmission pipe 9, so that the bristles 13 move back and forth on the surface of the filter element, thereby cleaning the filter element, thereby maintaining the cleanliness of the filter element and avoiding affecting the gas purification degree under long-term operation.

[0025] When the dust suction pipe 19 is connected to the rock drilling rig, the rubber ring 20 is put on one end of the pipe next to the drill bit of the rock drilling rig, so that the reinforcement ring 21 is put on the outside of the pipe, and the connecting plate 22 is inserted into one side of the reinforcement ring 21 to make a preliminary connection at the opening of the reinforcement ring 21. Then, the bolt 24 is inserted into the reinforcement ring 21, and the bolt 24 is rotated at the same time so that the tail end is screwed into the fixing nut 23 and cooperates with the limit plate 25 to reduce the size of the opening of the reinforcement ring 21, thereby reducing the circle dimension of the reinforcement ring 21, improving the fit between the rubber ring 20 and the rock drilling rig pipe, and then improving the tightness of the connection between the dust suction pipe 19 and the rock drilling rig, thereby avoiding the dust suction pipe 19 from falling off the rock drilling rig due to excessive vibration during the operation of the rock drilling rig.
[0026] Working principle: put the rubber ring 20 on one end of the pipe next to the drill bit of the rock drilling rig, so that the reinforcement ring 21 is put on the outside of the pipe, turn the bolt 24, screw its tail end into the fixing nut 23, and cooperate with the limit plate 25 to reduce the size of the opening of the reinforcement ring 21, thereby reducing the circle dimension of the reinforcement ring 21, improving the tightness of the connection between the dust suction pipe 19 and the rock drilling rig, and then connect the dust suction pipe 19 to the rock drilling rig, and then start the fan to suck the dust gas generated by the rock drilling rig into the dust suction pipe 19, filter it through the filter element and discharge it outward, and drive the water pump 10 to pump the clean water in the water tank 11 into the hollow connecting ring 12, and flow to the surface of the filter element through the water outlet 14, and then start the drive motor 4 to drive the screw 5 to rotate, adjust the position of the adjustment block 6 and the connecting block 7, and the transmission pipe 9 moves synchronously. When the connecting block 7 moves, the hollow connecting ring 12 is driven to move synchronously through the transmission pipe 9, so that the bristles 13 move back and forth on the surface of the filter element, thereby cleaning the filter element.
