Description

Technical Field

[0001] The present invention belongs to the technical field of dust removal for roadheaders, and specifically relates to a dust removal roadheader device. Background Art

[0002] A roadheader is a machine used to excavate roadways on flat ground. As the traveling mechanism advances forward, the cutting head in the working mechanism continuously breaks rocks and transports the crushed rocks away. Since the cutting of the rock by the cutting part generates a large amount of dust, these dusts cannot dissipate in the enclosed roadway, resulting in a very high dust concentration in the roadway. These dusts cause low visibility and inability to operate continuously, and also cause great harm to the health of the personnel constructing in the roadway. Therefore, the dust removal device plays a crucial role.

[0003] In the Chinese patent with the publication number CN219262437U, a dust removal integrated device for coal mine roadways is mentioned, including a moving mechanism, a diversion mechanism, a collection mechanism, and a stabilization mechanism; the diversion mechanism is installed inside the moving mechanism; the collection mechanism is installed on the moving mechanism; the stabilization mechanism is installed on the moving mechanism; the moving mechanism includes: a moving seat, support rods, and a dust removal cylinder; the moving seat is a rectangular plate-like structure; there are two support rods in total, and the two support rods are fixedly installed on the top of the moving seat; the dust removal cylinder is fixedly installed on the top of the two support rods; because the collection hood is fixedly installed at the bottom of the dust removal cylinder, and the dust collection box is slidably installed inside the collection hood, the dust inside the dust removal cylinder automatically falls into the dust collection box under the action of gravity, realizing the automatic collection of dust, facilitating the staff to centrally process the dust. Also, because the limit knob is threadedly connected to the collection hood and contacts the dust collection box, it further plays a limiting role on the dust collection box, making the dust collection box more stable during use.

[0004] However, when sucking dust with the above technical solution, it is not convenient to adjust the sucking position, reducing the flexibility of the device in use.

[0005] Therefore, those skilled in the art have proposed a dust removal roadheader device to solve the problems raised in the background art. Summary of the Invention

[0035] As shown in the attached Figure 1 to the attached Figure 7 figures:

[0036] Embodiment 1:

[0037] The present invention provides a dust removal tunneling device, which includes a dust removal box body 1. Suction mechanisms 2 are symmetrically installed on the front side of the dust removal box body 1. One end of the suction mechanism 2 is communicated with the inside of the dust removal box body 1. Moving adjustment mechanisms 3 are respectively installed on the left and right side walls of the dust removal box body 1 on both sides of the suction mechanism 2. One end of the suction mechanism 2 away from the dust removal box body 1 is connected to the moving adjustment mechanism 3. A spraying mechanism 4 is installed on the top wall of the dust removal box body 1. The spraying mechanism 4 penetrates and extends into the inside of the dust removal box body 1. Slideway assemblies 5 are symmetrically arranged on the inner side wall of the dust removal box body 1. A filter collection assembly 6 is movably installed in the slideway assembly 5. A storage box 7 is movably installed on the bottom wall of the dust removal box body 1. A water level sensor 10 is arranged on the inner side wall of the storage box 7. An exhaust assembly 8 is communicated with the left outer side wall of the dust removal box body 1 and is located between the filter collection assembly 6 and the storage box 7. A circulation mechanism 9 is arranged on the right outer side wall of the dust removal box body 1. The other end of the circulation mechanism 9 is communicated with the spraying mechanism 4. Cooling assemblies 14 are installed on the left and right side walls of the dust removal box body 1. Connecting seats 15 are symmetrically installed at the bottom of the dust removal box body 1. An access door is installed on the rear side wall of the dust removal box body 1;

[0038] Among them, the moving adjustment mechanism 3 includes a motor box 11, an installation box 12 and a moving component 13. The motor box 11 and the installation box 12 are fixedly installed on the side wall of the dust removal box body 1. The moving component 13 is movably installed in the motor box 11. The motor box 11 is electrically connected to the moving component 13. One end of the suction mechanism 2 is installed on the moving component 13.

[0039] Specifically, the suction mechanism 2 includes a suction pipe 20, a suction hood 21 and a first suction motor 22. The first suction motor 22 is installed on the side wall of the dust removal box body 1. One end of the suction pipe 20 is installed on the side wall of the dust removal box body 1 and is communicated with the first suction motor 22 and the inside of the dust removal box body 1. The suction hood 21 is threadedly connected to one end of the suction pipe 20 away from the dust removal box body 1.

[0040] Specifically, the suction pipe 20 includes a hose part and a hard pipe part. The hard pipe parts are connected to both ends of the hose part, and the hose part and the hard pipe part are integrally formed. One hard pipe part is communicated with the dust removal box body 1, and the other hard pipe part is installed on the moving component 13.

[0041] Specifically, the moving component 13 includes a threaded adjustment rod 23, a movable sleeve 24, a moving block 25 and a mounting plate 26. The threaded adjustment rod 23 is rotatably installed in the installation box 12 through a bearing. The movable sleeve 24 is threadedly installed on the threaded adjustment rod 23. One end of the moving block 25 is connected to the movable sleeve 24, and the other end extends to the outside of the installation box 12. The mounting plate 26 is connected to the outer end of the moving block 25. The other hard pipe part is installed on the mounting plate 26. A power motor is arranged in the motor box 11, and the output end of the power motor is connected to the threaded adjustment rod 23.

[0042] As can be seen from the above, during the tunneling process, the suction position is adjusted by moving according to the main sources of dust generation. Specifically, the power motor is started to drive the threaded adjusting rod 23 to rotate, so that the movable sleeve 24, the moving block 25 and the mounting plate 26 move. Since the suction pipe 20 is installed on the mounting plate 26, when the mounting plate 26 moves, the suction pipe 20 and the suction hood 21 are driven to move, thereby adjusting the position of sucking dust and improving the flexibility of the device.

[0043] Specifically, the spraying mechanism 4 includes a spraying water tank 27, a spraying pipe 28 and three spraying heads 29. The spraying water tank 27 is installed on the top wall of the dust removal box body 1. One end of the spraying pipe 28 is communicated with the spraying water tank 27, and the other end is installed on the inner top wall of the dust removal box body 1. The spraying pipe 28 is used in cooperation with a water pump, and the three spraying heads 29 are all communicated with the spraying pipe 28.

[0044] Specifically, the circulating mechanism 9 includes a circulating water pipe 36, a connecting pipe 37 and a suction water pump 38. The connecting pipe 37 is installed on the side wall of the dust removal box body 1 and is communicated with the storage box 7. The suction water pump 38 is communicated with the connecting pipe 37. One end of the circulating water pipe 36 is installed on the suction water pump 38, and the other end is communicated with the spraying water tank 27.

[0045] As can be seen from the above, when the dusty air enters the dust removal box body 1, the spraying pipe 28 and the water pump are used in cooperation, and the spraying heads 29 are used to reduce the dust in the dusty air. The excess water enters the storage box 7. When the water in the storage box 7 reaches the water level sensor 10, the water level sensor 10 controls the suction water pump 38, so that the water enters the spraying water tank 27 through the connecting pipe 37 and the circulating water pipe 36 for recycling, saving water resources.

[0046] Specifically, the chute assembly 5 includes a chute 30 and a fixing bolt 31. The chute 30 is fixedly arranged on the inner side wall of the dust removal box body 1. An installation hole one is opened on the top wall at the front end of the chute 30, and the fixing bolt 31 is installed in the installation hole one.

[0047] Specifically, the filtering and collecting assembly 6 includes a mounting frame 32, a filter screen 33 and a collecting box 34. The filter screen 33 is fixedly connected to the inner wall of the mounting frame 32. The collecting box 34 is installed on the filter screen 33. Installation holes two 35 are opened on both sides of the mounting frame 32. The installation holes two 35 correspond to the installation hole one and are fixed by the fixing bolt 31.

[0048] As can be seen from the above, the filtering and collecting assembly 6 is movably installed in the chute 30 and is installed and fixed by the fixing bolt 31, so that the filtering and collecting assembly 6 is convenient for installation and disassembly; during the process of reducing dust by using the spraying mechanism 4, the condensed dust can fall into the collecting box 34, and for the part of the dust that does not fall into the collecting box 34, the filter screen 33 is used for filtering, and the excess water falls into the storage box 7 for storage.

[0049] Specifically, the exhaust assembly 8 includes an exhaust pipe 41 and a second suction motor 42. The second suction motor 42 is installed on the outer side wall of the dust removal box 1. The exhaust pipe 41 is installed on the second suction motor 42 and is connected to the inside of the dust removal box 1.

[0050] Embodiment 2:

[0051] In this embodiment, the cooling assembly 14 in the present invention can cool the hot air generated during tunneling;

[0052] Specifically, as Figure 2 shown, the cooling assembly 14 includes a refrigeration box 39 and a refrigeration pipe 40. The refrigeration box 39 is installed on the outer side wall of the dust removal box 1. The refrigeration pipe 40 is connected to the refrigeration box 39 and is located inside the dust removal box 1.

[0053] As can be seen from the above, the hot air entering the dust removal box 1 can be cooled by the refrigeration box 39 and the refrigeration pipe 40 and then discharged, reducing the occurrence of dangerous accidents due to too high temperature in the air.

[0054] Embodiment 3:

[0055] This embodiment relates to the working principle of the present invention. The present invention is designed to remove dust generated during tunneling. The present invention mainly uses the moving assembly 13 to adjust the position of the suction mechanism 2 to move and adjust the suction position. The specific working principle steps are as follows:

[0056] S1. First, install the dust removal box 1 on the relevant installation base of the tunneling machine through the connecting seat 15. The connecting seat 15 can be installed using bolts.

[0057] S2. Turn on the first suction motor 22, and suck the dusty air into the dust removal box 1 through the suction pipe 20 and the suction hood 21. During tunneling, the power motor can be started to drive the threaded adjustment rod 23 to rotate, so that the movable sleeve 24, the moving block 25 and the mounting plate 26 move. Since the suction pipe 20 is installed on the mounting plate 26, while the mounting plate 26 moves, it drives the suction pipe 20 and the suction hood 21 to move, so as to conveniently move and adjust the suction position according to the main source of dust generation;

[0058] S3. During the suction process, the spray pipe 28 and the water pump are used in cooperation, and the spray head 29 dusts the dusty air. The condensed dust can fall into the collection box 34. For some dust that does not fall into the collection box 34, it is filtered by the filter screen 33. The excess water falls into the storage box 7 for storage. When the water in the storage box 7 is stored to the water level sensor 10, the water level sensor 10 controls the suction water pump 38, so that the water enters the spray water tank 27 through the connecting pipe 37 and the circulating water pipe 36 for recycling;

[0059] In the above process, by starting the second suction motor 42, the air after dust reduction is discharged outside the dust removal box body 1.

[0060] The embodiments of the present invention are given for the purposes of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
