Abstract
The utility model provides a gravity impact drill. A lower transverse rod is fixed on the lower part of a lengthened drilling rod; an upper transverse rod is fixed on the lengthened drilling rod at a certain distance; an upper slide sleeve is arranged in the middle of the upper transverse rod and a lower slide sleeve is arranged in the middle of the lower transverse rod; the two slide sleeves are internally provided with a slide rod; tooth-shaped strips are fixed at the left side of the slide rod and a baffling block is arranged at the lower parts of the tooth-shaped strips of the slide rod; a supporting rod is arranged at the left sides of the tooth-shaped strips; the upper end of the supporting rod is fixed on the left end of the upper transverse rod; the lower end of the supporting rod is fixed on the left side of the lower transverse rod; a driver is arranged in the middle of the supporting rod; a semi-tooth ring is fixed on the periphery of the driver; a heavy hammer is arranged at the lower end of the slide rod; and hammer teeth are arranged at the lower part of the heavy hammer.
Description
Technical field
The utility model relates to a kind of Churn drill, the gravity Churn drill of particularly using in a kind of borehole engineering.
Background technology
At present, the Churn drill of using in the borehole engineering all is that power places outside the hole, with the oil thread rope drill hammer impinge upon earth strata pore-forming that plays, causes thus power loss huge.
Summary of the invention
The utility model has remedied above shortcoming, and a kind of gravity Churn drill is provided.
The utility model is achieved by the following technical solution:
A kind of gravity Churn drill, the extension arm bottom is sheer pole fixedly, fixedly cross tube keeps at a certain distance away on the extension arm, be provided with slip cap in the middle of the cross tube, be provided with the lower slider cover in the middle of the sheer pole, be provided with sliding bar in two slip caps, the left side of sliding bar is the profile of tooth bar fixedly, profile of tooth bar bottom is provided with block on the sliding bar, the profile of tooth bar left side is provided with support bar, and post upper is fixed in the cross tube left end, and the sheer pole left end is fixed in the support bar lower end, be provided with driver in the middle of the support bar, the driver circumference is fixed half ring gear; The sliding bar lower end is provided with weight, and the weight bottom is provided with the hammer tooth.
The utlity model has following characteristics:
When the utility model driver drives half ring gear rotates, have the part of tooth to raise by profile of tooth bar driving weight on half ring gear, part anodontia on half ring gear is not because driving the profile of tooth bar, weight drop impinge upon earth strata pore-forming, power free of losses.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is structural representation of the present utility model;
Among the figure: 1, extension arm, 2, cross tube, 3, upper slip cap, 4, sheer pole, 5, the lower slider cover, 6, sliding bar, 7, block, 8, support bar, 9, driver, 10, half ring gear, 11, weight, 12, the hammer tooth, 13, the profile of tooth bar.
The specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model, this embodiment extension arm 1 bottom is sheer pole 4 fixedly, fixedly cross tube 2 keeps at a certain distance away on the extension arm, be provided with slip cap 3 in the middle of the cross tube, be provided with lower slider cover 5 in the middle of the sheer pole, be provided with sliding bar 6 in two slip caps, the left side of sliding bar is profile of tooth bar 13 fixedly, profile of tooth bar bottom is provided with block 7 on the sliding bar, the profile of tooth bar left side is provided with support bar 8, and post upper is fixed in the cross tube left end, and the sheer pole left end is fixed in the support bar lower end, be provided with driver 9 in the middle of the support bar, the driver circumference is fixed half ring gear 10; The sliding bar lower end is provided with weight 11, and the weight bottom is provided with hammer tooth 12.
During the utility model work, driver drives half ring gear rotates counterclockwise, and has the moving sliding bar of part driving profile of tooth band, the weight of tooth to move upward on half ring gear, when half ring gear turns over anodontia partial arc, because not driving the profile of tooth bar, sliding bar, weight fall, impinge upon earth strata.
