Abstract
The utility model relates to a dust collector of a drilling machine, which comprises a dust collecting barrel and a fan. An air door is arranged at the upper end of the dust collecting barrel, the fan is disposed above the air door, and an air door closing device which is used for closing and sealing the air door is arranged in the dust collecting barrel. The dust collector of the drilling machine has the advantages that the dust collector is simple in structure, the air door can be tightly closed when in reverse blowing, so that the inside of the dust collector does not have suction force, dust on a filter element can be blown away easily, and accordingly dust accumulation in the dust collector can be prevented.
Description
Technical field
The utility model relates to a kind of dust collect plant, particularly a kind of rig dust arrester.
Background technology
The dust arrester of the control form of blowback again after present rig generally adopts high speed piston motor direct connection fan form and blowback control to adopt the rig probing to finish.The centrifugal force that the high speed piston motor drives the generation of fan high speed rotary makes air obtain kinetic energy, through spiral case and spiral case outlet diffuser part kinetic energy is converted into static pressure then.Like this, the air of blower fan outlet is exactly have a constant static-pressure distinguished and admirable, utilizes the distinguished and admirable dust that produces when collecting rig boring, after the rig probing finishes automatically to the filter core purge.But dust arrester is when the blowback dedusting, and air door is not closed, and makes dust arrester produce suction in blowback, then is difficult to blow off dust, and accumulation can make filter core block for a long time, thereby dust collecting effect is reduced.
Summary of the invention
The purpose of this utility model is exactly the weak point in the background technology, and a kind of rig dust arrester is provided,
Be provided with the air door shutoff device that air door can be closed in it.
For achieving the above object, the utility model adopts following technical scheme: the rig dust arrester, comprise dust bucket and fan, and the dust bucket upper end is provided with air door, and the air door top is provided with fan, is provided with the air door shutoff device that air door is closed tightening seal in the described dust bucket.
For a kind of optimization of the present utility model, described air door shutoff device comprises air door cover plate, supporting plate, cylinder and cushion pad, cylinder is fixed on the fixed mount that is used to install element kit in the dust bucket, cylinder is positioned at the fixed mount below, its upper end tailpiece of the piston rod is connected with the center of air door cover plate and supporting plate respectively, is respectively arranged with cushion pad between air door cover plate and the supporting plate and between cylinder block and the fixed mount.
The utility model is compared with background technology, has simple in structurely, and dead the air door pass when blowback, making does not have suction in the dust arrester, can blow the dust on the filter core easily off, thereby prevents that dust is piled up in the dust arrester.
Description of drawings
Fig. 1 is the structural representation of rig dust arrester.
Fig. 2 is the user mode figure of rig dust arrester.
The specific embodiment
Embodiment 1: with reference to Fig. 1 and 2.A kind of rig dust arrester comprises dust bucket 10 and fan 1, and dust bucket 10 upper ends are provided with air door 2, and air door 2 tops are provided with fan 1, is provided with the air door shutoff device 11 that air door 2 is closed tightening seal in the described dust bucket 10.Described air door shutoff device 11 comprises air door cover plate 3, supporting plate 5, cylinder 8, cushion pad 4 and cushion pad 7, cylinder 8 is fixed on the fixed mount 9 that is used to install element kit in the dust bucket 10, cylinder 8 is positioned at fixed mount 9 belows, its upper end tailpiece of the piston rod 6 is connected with the center of air door cover plate 3 with supporting plate 5 respectively, is respectively arranged with cushion pad 4 and cushion pad 7 between air door cover plate 3 and the supporting plate 5 and between the cylinder body of cylinder 8 and the fixed mount 9.
What need understand is: though present embodiment is to the utility model detailed explanation of contrasting; but these explanations; just to simple declaration of the present utility model; rather than to restriction of the present utility model; any the utility model that do not exceed is meant spiritual interior innovation and creation, all falls in the protection domain of the present utility model.
Claims (2)
