[0002] The multi-functional tunneling machine has many functions such as coal mine excavation, rock loading, and coal mining. It is the most common and advanced tunneling machinery in underground coal mines, and plays a very important role in the mechanized production of modern coal mine excavation.

[0003] At present, in order to prevent the dust generated during the excavation process from affecting the workers' vision, the existing multi-purpose excavator is equipped with a spray component on the machine body, which can spray water mist to the contact point between the excavation cutter head and the coal rock while cutting the coal rock. Since the multi-purpose excavator will generate a large amount of dust when in use, the effect of dust removal by relying solely on spraying is not very ideal. The dust in the air near the excavation cutter head cannot be fully removed, which will affect the normal work of the staff. For this reason, we propose a dust removal device for a multi-purpose excavator in coal mines to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-5 A dust removal device for a coal mine underground excavator comprises an excavator body 1, a mounting column 2 is connected to the front end of the excavator body 1, and an excavation head 3 is installed at the end of the mounting column 2, a connecting ring 4 is sleeved on the outer side of the mounting column 2, and telescopic tubes 12 are evenly inserted inside the connecting ring 4, and the ends of the telescopic tubes 12 are all connected with dust suction heads 5, the side of the connecting ring 4 is connected to a collecting box 7 through a first connecting tube 6, and the collecting box 7 is installed at the top of the excavator body 1, an air pump 8 is provided on the side of the collecting box 7, and the inside of the air pump 8 is connected to the collecting box 7 through a second connecting tube 9, the collecting box 7 is large in size, so that the staff does not need to clean it frequently, and the collecting box 7 is set to a transparent material, so that the staff can check the storage volume inside it conveniently, the air pump 8 is a prior art, and can attract the generated dust to the inside of the collecting box 7, and the side wall of the collecting box 7 is distributed with a covering plate 13.

[0024] Further, see Figure 3 It can be known that the top end of the telescopic tube 12 is connected to the cylinder 10 through the rectangular block 11, and the bottom end of the cylinder 10 is connected to the outer wall of the connecting ring 4. The telescopic principle of the cylinder 10 is a prior art and will not be elaborated here. It can drive the telescopic tube 12 to continuously reciprocate and extend to increase the absorption range of the dust collector head 5.

[0025] Further, see Figure 4 and Figure 5 It can be known that the inner side of the covering plate 13 is symmetrically connected with a connecting rod 14, and the other end of the connecting rod 14 is connected to the pushing plate 15. By setting the connecting rod 14, the connection between the covering plate 13 and the pushing plate 15 can be achieved. When it is necessary to clean the dust inside the collecting box 7, the staff can pull the covering plate 13, so that the pushing plate 15 is pushed inside the collecting box 7 to push out the dust inside the collecting box 7.

[0026] Further, see Figure 4 and Figure 5It can be known that an electric slide 16 is provided at the top of the collection box 7, and the top of the push plate 15 extends to the inside of the electric slide 16. The working principle of the electric slide 16 is to control the motor to drive the screw to drive the movement of the slider, and the slider and the top of the push plate 15 are connected, so that on this basis, the connecting rod 14 can be smoothly moved in the collection box 7 to automatically push out the dust inside the collection box 7. The specific operating principle of the electric slide 16 is the existing technology and will not be elaborated here. Through the setting of the electric slide 16, the collection box 7 does not need to be manually cleaned by the staff.

[0027] Further, see Figure 5 It can be seen that the side wall of the collecting box 7 is provided with a hole adapted to the second connecting pipe 9, and the inner wall of the hole is connected to a filter 17. The setting of the filter 17 can effectively prevent dust and debris from entering the interior of the air pump 8 to ensure the normal operation of the air pump 8.

[0028] Further, see Figure 4 It can be seen that a sealing strip is connected to the inner side of the covering plate 13, and a sealing groove matched with the sealing strip is opened on the side of the collecting box 7, and the longitudinal section of the sealing groove and the sealing strip is arranged as a U-shaped structure. The sealing groove and the sealing strip arranged in the U-shaped structure are not shown in the figure. Through the mutual cooperation of the two, the tightness of the covering plate 13 when covering the side of the collecting box 7 can be effectively guaranteed.

[0029] Further, see Figure 3 It can be known that the side of the telescopic tube 12 away from the vacuum head 5 is connected to the connecting ring 4 through a thread, and there are two groups of rectangular blocks 11, one group of which is connected to the side of the telescopic tube 12, and the other group of rectangular blocks 11 is connected to the top of the cylinder 10. The two groups of rectangular blocks 11 are connected by bolts, and a threaded groove is provided at the position corresponding to the telescopic tube 12 inside the connecting ring 4. When a single telescopic tube 12 is damaged, the staff can use tools to disassemble the rectangular block 11 connected to the side and the rectangular block 11 connected to the top of the cylinder 10, and then rotate the telescopic tube 12 to remove it from the inside of the connecting ring 4 for replacement.

[0030] Working principle: When the utility model is used, the staff can first drive the comprehensive excavation machine body 1, and cooperate with the excavation head 3 set at the front end of the comprehensive excavation machine body 1 to realize the excavation and mining of the coal mine. During the excavation process of the excavation head 3, water mist will be sprayed inside it to achieve the purpose of preliminary dust removal. In addition, through the operation of the air pump 8, the generated dust can pass through the dust suction head 5, the telescopic tube 12, the connecting ring 4 and the first connecting tube 6 in turn and enter the interior of the collection box 7 for collection. During the process of the dust suction head 5 attracting dust, the cylinder 10 can be started intermittently, so as to drive the telescopic tube 12 to move back and forth continuously. It can be extended and retracted to increase the suction range of the dust suction head 5, thereby effectively ensuring the dust suction effect. During the excavation process, when the collection box 7 is almost full, the staff can remotely control the operation of the electric slide 16, so that it can drive the push plate 15 to move inside the collection box 7 to push out the dust particles collected inside the collection box 7. After the pushing is completed, the push plate 15 can be reset by the electric slide 16, so that the cover plate 13 is again in contact with the side wall of the collection box 7 to achieve the sealing of the collection box 7, which is convenient for subsequent continued use. The above is the entire working principle of the utility model.

[0031] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

[0032] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
