Description

Technical Field

[0001] The utility model belongs to the technical field of sweepers, and in particular relates to a sweeper used in underground coal mines. Background Art

[0002] Cleaning and tidying up the underground working environment in coal mines is a key link in ensuring production safety and improving work efficiency. The underground working environment in coal mines is complex and changeable. Not only is the space small and the light insufficient, but it is also often accompanied by the generation of a large amount of granular garbage such as slag, coal dust, and rock fragments. If these garbage are not cleaned up in time, they will not only accumulate in important areas such as tunnels and working faces, affecting the normal operation of equipment and the safety of workers' passage, but may also cause sparks due to friction and impact, increasing the risk of safety accidents such as coal mine explosions and fires.

[0003] Traditionally, cleaning operations in coal mines mainly rely on manual handheld vacuum pumps or brooms. Workers need to bend over or squat, put the nozzle of the vacuum pump or broom close to the ground, and clean up the garbage one by one. This operation method is not only labor-intensive and inefficient, but also requires long-term operation in an environment with high dust concentration, posing a serious threat to workers' respiratory system, skin and other health. In recent years, with the continuous improvement of the mechanization and automation level of coal mines, some coal mining companies have begun to try to introduce mechanized cleaning equipment, such as electric sweepers and vacuum trucks. However, most of these devices are designed for ground or open-air environments. Their size, weight, power system, etc. are not suitable for the special environment of coal mines. Utility Model Content

[0027] Please refer to Figure 1 - Figure 3 As shown in the figure, specifically, the adjusting frame 21 is fixedly arranged on the top end of the vehicle body 1 away from the cavity 12, the threaded rod 22 is movably arranged in the adjusting frame 21 through a bearing, the threaded block 23 is threadedly screwed on the outer side of the threaded rod 22, the threaded block 23 is in sliding fit with the inner wall of the adjusting frame 21, the servo motor 24 is arranged on the outer side of the adjusting frame 21 close to the threaded rod 22 through a fixed seat, the output end of the servo motor 24 is in transmission connection with the shaft of the threaded rod 22 through a shaft coupling, the through slot 25 is arranged on the side of the vehicle body 1 close to the adjusting frame 21, the through slot 25 is arranged corresponding to the adjusting frame 21, the lifting rod 26 is movably arranged in the through slot 25, the lifting rod 26 is fixedly connected to the threaded block 23 on the side close to the threaded block 23, and the connecting plate 27 is fixedly arranged on the output end of the lifting rod 26.

[0028] As can be seen from the above, the dust suction pump 13 is arranged in intercommunication with the inside of the cavity 12, the dust suction pump 13 draws the garbage on the ground into the inside of the cavity 12 through the dust suction port 15 and the hose 14, the threaded rod 22 is driven to rotate by the servo motor 24, and then moves the threaded block 23 back and forth in the adjusting frame 21 by rotating, and in this way, the lifting rod 26 is driven to move synchronously, the lifting rod 26 drives the dust suction port 15 to move through the clamping frame 28, and the lifting rod 26 can also drive the dust suction port 15 to move close to or away from the ground, so as to realize full coverage of the cleaning area.

[0029] In use, first start the dust suction pump 13, and then start the servo motor 24, the servo motor 24 drives the threaded rod 22 to rotate, the threaded rod 22 drives the threaded block 23 to move back and forth, and the clamping frame 28 drives the dust suction port 15 to move synchronously, and the cleaning work is completed.

[0030] Example two:

[0031] Please refer to Figure 3 -Figure 4 As shown, the clamping frame 28 is fixedly installed on one side of the connecting plate 27, two lead screws 29 are movably installed in the clamping frame 28 through bearings, the two lead screws 29 are fixedly connected between them, the outer sides of the two lead screws 29 are oppositely threaded, and the outer sides of the two lead screws 29 are movably installed with movable blocks 210 through threaded engagement.

[0032] Please refer to Figure 4 As shown, specifically, a knob 211 is movably installed on the outer side of the clamping frame 28 close to one side of the lead screw 29, the knob 211 is in transmission connection with the shaft of the lead screw 29, a connecting strip 212 is fixedly installed on the side of the movable block 210 away from the clamping frame 28, a clamping plate 213 is fixedly installed on the end of the connecting strip 212 away from the movable block 210, the clamping plate 213 has a C-shaped structure in cross section, and the clamping plate 213 is in abutment with the outer wall of the dust suction port 15.

[0033] As can be seen from the above, since the outer sides of the two lead screws 29 are oppositely threaded, when the knob 211 drives the lead screw 29 to rotate, it will drive the two movable blocks 210 to approach or move away from each other, and in turn synchronously drive the clamping plates 213 to approach each other, thereby achieving the clamping effect of the dust suction port 15.

[0034] In use, first introduce the dust suction port 15 below the vehicle body 1 and place it on one side of the clamping frame 28, then rotate the knob 211 to drive the lead screw 29 to rotate, at this time the two movable blocks 210 are caused to approach each other by the action of the lead screw 29, and at the same time drive the clamping plates 213 to approach the dust suction port 15, until the dust suction port 15 is clamped, and finally start the servo motor 24 to drive the dust suction port 15 to move back and forth horizontally to perform cleaning work.

[0035] The present application can be applied to the cleaning work in large coal mine underground, because the slag, coal dust and other garbage generated in the mining process appear frequently, which seriously affects the operation efficiency, normal operation of equipment and workers' health.
