Description

Technical Field

[0001] This utility model relates to the field of mining blasting technology, specifically a mining blasting hole cleaning device. Background Technology

[0002] Mining blasting holes refer to a technique used in mining operations where holes are drilled and filled with explosives for blasting. Blasting holes are primarily used to break rocks and ores to facilitate mineral extraction. To improve blasting effectiveness, the inner walls of the mining blasting holes need to be cleaned.

[0003] A cleaning device for open-pit blasting holes disclosed in CN220195780U has a welded fixed connection between the entire clamp sleeve and the dust suction rod. Its groove adopts a structure design that is smaller at the top and larger at the bottom, which can effectively constrain and protect the plate frame. At the same time, this structure also facilitates the need for quick disassembly of the plate frame during subsequent use, providing convenience for users.

[0004] However, this mining blast hole cleaning device has the following disadvantages:

[0005] (1) The cleaning function of the mining blast hole cleaning device is weak. When using the device, it cannot brush the dust on the inner wall of the hole. When the device is vacuuming, the dust on the inner wall of the hole may be too tightly adsorbed and cannot be vacuumed, which may cause the cleaning effect of the inner wall of the hole to be poor.

[0006] (2) The protective function of the mining blast hole cleaning device is relatively weak. When in use, the device will first break the rocks in the hole before absorbing the dust in the inner wall of the hole. However, the device may not be able to completely break the rocks in the hole, which may cause the dust suction device to suck in large rocks and cause internal damage. Utility Model Content

[0007] The purpose of this invention is to provide a mining blast hole cleaning device to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a mining blasting hole cleaning device, comprising a fixed plate, a fixed rod fixedly connected to the bottom of the fixed plate, a connecting cylinder provided on the outer surface of the fixed rod, a rectangular groove formed on the outer surface of the connecting cylinder, an adjusting plate snapped into the inner wall of the rectangular groove, a docking plate fixedly connected to the side of the adjusting plate, a circular slot formed on the outer surface of the docking plate, a spring fixedly connected to the inner wall of the circular slot, a docking ball fixedly connected to one end of the spring, a cleaning brush fixedly connected to one end of the adjusting plate, a dust suction rod fixedly connected to the top of the fixed plate, a dust suction head fixedly connected to one end of the dust suction rod, a fixing bolt threadedly connected to the top of the dust suction head, a fixing cover threadedly connected to one end of the fixing bolt, a protective net fixedly connected to the outer surface of the fixing cover, and a rubber sleeve fixedly connected to the bottom of the inner wall of the fixing cover.

[0009] Preferably, the bottom of the fixing rod is provided with an arc-shaped groove, and a crushing blade is fixedly connected to the inner wall of the arc-shaped groove. Workers can use the crushing blade on the fixing rod to crush the stones at the bottom of the inner wall of the blasting hole.

[0010] Preferably, the inner wall of the spring is provided with a telescopic rod, one end of which is fixedly connected to the center of the back of the ball, and the telescopic rod can prevent the spring from tilting.

[0011] Preferably, one end of the docking plate is slidably connected to a sliding groove, and the inner wall of the sliding groove is provided with a retaining groove. The inner wall of the retaining groove is engaged with one end of the docking ball. The docking plate docks in the sliding groove, and the docking ball docks with the retaining groove on the inner wall of the sliding groove.

[0012] Preferably, the top two ends of the fixing plate are provided with circular slots, and friction pads are fixedly connected to the inner walls of the circular slots. The friction pads provided on the fixing plate can facilitate the staff to hold the device.

[0013] Preferably, the top of the fixing cover is provided with a threaded groove, and the inner wall of the threaded groove is threaded to one end of the fixing bolt, and one end of the fixing bolt is screwed into the inner wall of the fixing cover.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This mining blast hole cleaning device, through the arrangement of a fixed rod, connecting cylinder, adjusting plate, docking plate, spring, docking ball, and cleaning brush, allows the operator to adjust the length of the adjusting plate on the inner wall of the connecting cylinder according to the size of the hole when dust on the inner wall of the blast hole cannot be sucked away. The docking plate on the adjusting plate will move on the inner wall of the connecting cylinder, and the docking ball on the docking plate will be locked in the slot on the inner wall of the connecting cylinder, allowing the cleaning brush on the adjusting plate to rotate and brush against the inner wall of the blast hole. This arrangement can improve the cleaning effect of the inner wall of the blast hole inside the device.

[0016] 2. This mining blast hole cleaning device, with its suction rod, suction head, fixing bolts, fixing cover, protective net, and rubber sleeve, requires the operator to cover the suction head with the fixing cover before suction, screw the fixing bolts into the threaded grooves corresponding to the suction head, and let the protective net on the fixing cover cover the suction head. The rubber sleeve inside the fixing cover is fitted onto the suction rod. This setup prevents incompletely broken stones from entering the suction head when the operator starts it.
