It is an object of the invention to overcome the shortcoming of prior art, it is provided that a kind of small diameter hole device for dragging dregs, fishing juice effect is good, easy installation and removal.
For solving above technical problem, the technical scheme is that a kind of small diameter hole device for dragging dregs, it is different in that: it includes catcher pipe, pellet, basket and drill bit, mobilizable described pellet it is provided with and for holding the pellet seat of pellet in the tube chamber of described catcher pipe, described pellet seat is infundibulate, described billiards diameter is less than pellet seat upper shed place diameter, billiards diameter is more than pellet seat lower opening diameter, described catcher pipe upper end is provided with the first retention device of restriction pellet range of movement, catcher pipe lower end is provided with the second retention device stoping clinker to enter pellet seat, the lower end of described catcher pipe passes sequentially through reducing joint, basket, reamer is connected to drill bit, described drill bit medial wall is provided with dross device.
By above technical scheme, described first retention device and the second retention device are the round pin being horizontally through catcher pipe tube chamber.
By above technical scheme, described pellet is steel ball.
By above technical scheme, described dross device is steel wire or steel plate or iron plate, and the medial wall of described drill bit is provided with the hole being easily installed dross device.
By above technical scheme, described catcher pipe outer tube wall being symmetrically set with two the first grooves, be symmetrically arranged with two the second grooves before and after on described catcher pipe outer tube wall, described second groove is arranged on the lower section of described first groove.
Contrast prior art, the beneficial features of the present invention is as follows:
1), this small diameter hole device for dragging dregs, when descending, water in hole enters pellet seat, promote pellet upwards movable, first retention device can limit pellet and move all the way up, in hole, residue also enters basket with water, when stopping descending, pellet can fall to sealing pellet seat, making the water having been enter into drilling rod stay in drilling rod, it is to avoid time up, the residue entered in basket is washed away again by drilling rod internal water pressure, dross device also functions to block the effect of slightly larger residue simultaneously, and so forth up and down repeatedly, thus reaching to drag for the purpose of slag;
2), this small diameter hole device for dragging dregs, the middle lower end of pellet seat is provided with the second retention device being horizontally through pellet seat inner chamber, and the situation that the second retention device can prevent slightly larger clinker from entering pellet seat upper end and cause pellet can not seal pellet seat completely occurs;
3), this small diameter hole device for dragging dregs, be provided with drill bit, in hole, clinker is excessive so that when being difficult to pull out, it is possible to first passes through this drill bit and directly pulverizes clinker, then carries out dragging for slag, easy to use, time saving and energy saving;
4), this small diameter hole device for dragging dregs, catcher pipe outer tube wall on be provided with the first groove, the second groove, it is simple to above bore time fork fork, easy to use, drill bit is dismantled and the rock dust taken up, chip, iron filings etc. can be poured out, then basket is rinsed well, easy to clean.
Accompanying drawing explanation
