Abstract

The utility model discloses a tamping bar, which is formed by connecting a plurality of tamping bar units end to end. The axial outer surface of each tamping bar unit is provided with scales which are used for measuring the depth. The head of the first tamping bar unit is in a column shape. The tail parts of the first tamping bar unit and the tamping bar units which are located behind the first tamping bar unit are provided with column-shaped grooves, and the inner circumferential surfaces of the column-shaped grooves are processed with threads. The heads of the second tamping bar unit and the second tamping bar units arranged behind the second tamping bar unit are provided with screw rods, and the screw rods of the heads of the tamping bar units are matched with the grooves of the tail parts of the tamping bar units. The outer circumferential surfaces of the tail parts of the first tamping bar unit and the tamping bar units which are located behind the first tamping bar unit are provided with circular clamp grooves, and a padding plate is arranged in the clamp groove of the first tamping bar unit. The tamping bar has a simple structure, is convenient to carry and measure, and has the advantages of safety and reliability.

Description

Tamper

Technical field

The utility model relates to a kind of instrument that loads explosive in the blasting engineering in the past borehole, especially relates to a kind of tamper.

Background technology

When loading explosive toward borehole is interior, the amount of fill that needs to use the tamper tamping and measure explosive, present, used tamper generally is the simple and easy tamper that bamboo pole is done, and generally only has about 5 meters, the above does not have scale, as required, generally marks scale with adhesive plaster above the bamboo pole; Yet in or the Long-hole Bench Blasting height generally more than 10 meters, the length of simple and easy tamper own is inadequate; The frequent landing of adhesive plaster, certainty of measurement is inaccurate; About 5 meters on bamboo pole carries also inconvenient.

As from the foregoing, obviously there is defective in existing simple and easy tamper, and remains to be improved.

Summary of the invention

For the deficiencies in the prior art part, the utility model aims to provide a kind of tamper, and is to guarantee carrying, measure convenience, safe and reliable.

The technical solution adopted in the utility model: a kind of tamper, connected from beginning to end by some tampers unit and to form, be provided with the scale that fathoms in each tamper unit axial external surface, the first tamper unit header is cylindrical, the later tamper unit tail in the first tamper unit and the first tamper unit is provided with cylinder shape groove, inner peripheral surface at cylinder shape groove is processed with screw thread, the head of the tamper unit that the second tamper unit and the second tamper unit are later is provided with threaded rod, and the head threads bar of described tamper unit and the groove of described tamper unit tail are complementary; In the first tamper unit and the outer circumference surface of the afterbody of later all tamper unit, the first tamper unit be processed with an annular draw-in groove.

In the draw-in groove of the first tamper unit tail, be provided with backing plate.

Adopt said apparatus, when in borehole, loading explosive, according to blast hole depth, the head of tamper unit can be connected successively with afterbody, with the head tamping explosive of the first tamper unit, because all tamper unit are provided with scale, can also measure explosive payload; In addition, in the draw-in groove of the first tamper unit tail, be provided with backing plate, backing plate is supported on the ground surface of big gun hole, such convenient operation when connecting the second tamper unit, and safe and reliable, when connecting the second tamper unit, in the time of need connecting again the 3rd tamper unit, take off backing plate and be loaded on the draw-in groove of the second tamper unit tail, as required, with this repetitive operation.

The utility model is simple in structure, carries, measures conveniently, and is safe and reliable.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the first tamper cellular construction schematic diagram;

Fig. 3 is the second tamper cellular construction schematic diagram;

Fig. 4 is the backing structure schematic diagram;

In the accompanying drawing: 2 second tamper unit, 1 first tamper unit, 3 draw-in grooves, 4 backing plates, 5 grooves, 6 threaded rods, 7 pilot holes.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, be provided with the scale that fathoms in each tamper unit axial external surface, the unit of described scale is 10 centimetres, namely the tamper unit shaft is 10 centimetres to the distance of each compartment, the length of each tamper unit is 2 meters, diameter is 5 centimetres of steel pipes, and the first tamper unit 1 head is cylindrical, and end face is solid.The first tamper unit 1 and the first tamper unit 1 later tamper unit tail are provided with cylinder shape groove 5, are processed with screw thread at the inner peripheral surface of cylinder shape groove 5; The head of the tamper unit that the second tamper unit 2 and the second tamper unit 2 are later is processed with threaded rod 6, and the threaded rod 6 of described tamper unit header is complementary with the groove 5 of described tamper unit tail; In the first tamper unit 1 and the outer circumference surface of the afterbody of later all tamper unit, the first tamper unit 1 be processed with an annular draw-in groove 3, in the draw-in groove 3 of the first tamper unit 1 afterbody, be provided with backing plate 4, be provided with pilot hole 7 at backing plate 4, backing plate 4 is stuck in the draw-in groove 3 by the pilot hole 7 on the body, like this when connecting tamper, first the first tamper unit 1 is positioned in the big gun hole, the first tamper unit 1 hangs on the backing plate 4, connects the second tamper unit 2 more convenient again.
