[Detailed description of the invention] This invention is a new structure for a striking machine in which the operating mode of the chisel attached to the striking machine is moved away from the conventional sliding reciprocating mode along a cylindrical guide. It is related to.

The structure of conventionally used impact machines is as follows:
For example, as shown in Fig. 1, a reciprocating power piston 2 is built into a main body 1 of a striking machine, and compressed air is fed into an air chamber 3 to continuously apply reciprocating power to the reciprocating power piston 2. The striking force is transmitted to a chisel 4 located opposite the tip. The chisel 4 is located within the sheath 5 and performs striking work with its tip 6 while being guided by the circumferential surface in contact with the sheath 5. 7 is a compressed air introduction pipe, and 8 is an exhaust hole.

When performing rock drilling work or soil excavation work using such a conventional impact machine, the tip 6
Since the work efficiency cannot be improved only by vertical blows, the worker usually applies lateral pressure to the chisel 4 as a lever while continuing to strike with the tip 6. In very many cases, an additional moment is applied to the rock or soil near the tip 6 to peel it off while it remains rock-shaped. However, in conventional impact machines, in order to prevent seizure of the sliding surface between the chisel 4 and the sheath 5, measures such as installing a lubricant supply device on the sliding surface are taken to prevent accidents. However, when a striking machine is used under the above-mentioned working conditions, the occurrence of seizure accidents is almost inevitable.
Furthermore, the dust scattered when the tip 6 hits the chisel 4 enters the sliding part between the chisel 4 and the sheath 5, impeding smooth sliding movement and accelerating the frequent occurrence of seizure accidents. Therefore, improvements to the structure of conventional impact machines were desired.

In addition, in the conventional impact machine with the above structure, chisel 4
The tip 6 of the piston 2 is located on an extension of the center line of the reciprocating power piston 2, so that, for example, in a place deeper than the possible approach position of the impact machine, that is, in FIG. In some cases, such as when it was desired to drill the hole B in the direction shown in the figure, this would not be possible with the structure of the conventional impact machine.

The structure of the striking machine according to this invention will be explained in detail with reference to drawings showing an embodiment. In FIG. 3, 12 is an arm attached to the main body 11;
The tip of the arm 12 constitutes a bearing 13. The arm 12 is provided in a projecting state on one side of the main body 11,
The center of the bearing 13 is located at a position deviated from the center line XX in the operating direction of the reciprocating power piston 2 of the impact machine. A chisel 14 is formed in the shape of a hook, and one end of the chisel is pivotally supported on the bearing 13 by a pin 15 so that it can rotate around the pin 15. 17 is a striking part provided on the back side of the chisel 14, and when the striking force is applied to the striking part 17 by the reciprocating power piston 2, the tip 16 of the chisel
The structure is such that a striking force is transmitted substantially parallel to the center line XX.

When the structure of the blower is configured as described above,
As is clear from a comparison with the conventional device shown in Figure 1, there is no contact sliding surface between the chisel and the main body in the direction of the center line Even when used in such a manner, there is no risk of seizing accidents. Also,
In the proposed structure, the portion of the pin 15 where there is a slight contact and sliding action is located at a considerable distance from the tip 16, and therefore there is little possibility that dust that is scattered when struck by the tip 16 will enter. This allows for smooth and safe work to continue. Furthermore, although the example in FIG. 3 shows an example where the position of the tip 16 is a distance d away from the center line XX, by preparing chisels with different distances d, the applicable range of the operation mode It is possible to enlarge the hole B to a large width, and even in the case of the work mode shown in Fig. 2, it is possible to drill hole B extremely easily along that direction. It exhibits excellent and unique effects not found in other striking machines.
