The present invention relates to a protective device Assembly for drilling on the breed, designed to reduce noise that contains the input beam, one end of which is a drill end, and somosaguas housing surrounding the input beam and the perforator and the portion of the drill rod and drill the end of the feeding beam as the end somosaguas housing is stationary relative to the feed beam of the first protective portion, while the second protective portion mounted for movement relative to the feed beam in its longitudinal direction, both of the protective parts have a hole through which the drill rod is connected with the punch, moving when drilling on a feed beam, makes a move in the drilling process.
When drilling through rock using a drilling Assembly that contains one or more shafts mounted on the base, and the hammer, with mobility mounted on a feed bar mounted on the boom. The input beam is also often installed on the end of the boom can be moved in the longitudinal direction by means of a separate cradle, thereby providing the location of the feeding beam in the desired position and in the desired direction for drilling. Due to such diverse PE is Emesene boom and the feeding beam drilling unit equip different gear cylinders or hydraulic motors which are in themselves known, and which operate by means of fluid under pressure.
A typical problem when drilling rock is noise. The noise creates a punch acting on the head of the tool, and the tool acting on the breed, as well as other various movements, such as rotation, etc. Noise, which evenly and widely distributed in the surroundings, stored, creating more and more problems, especially near residential areas. To prevent noise, lest it lead to restrictions relating to hours of work or places of work, attempts have been made to solve this problem, in particular when drilling from the surface, through the use of a variety of somosaguas buildings around the feed beam, and a hole punch. Such solutions are known, for example, from the publications WO 2006/038850, WO 00/39412, patent, Sweden No. 523874, U.S. patent No. 3667571 and Japan patent JP5-295978. The problem with all these solutions is that they are difficult to implement, and they do not muffle the noise of the entire area of the punch. In particular, the damping of the noise at the end of the housing, where the drill bit and the drill rod out of the casing during drilling, has not been satisfactory. There are attempts to resolve this problem, for example, in the publication WO 2006/038851 through is definitely the solution for damping noise, in the case of which use two damping pipe installed in the longitudinal direction of the drill rod, which is movable relative to each other. The problem with this solution is that between the parts remains a gap, and the damping can not be provided with the required efficiency.

The boom 4 can represent any known in itself a construction, therefore, there is no need for a more detailed explanation regarding arrows. Known in itself in a way that the figure is not presented, the boom 4 is pivotally attached to the base 2 to allow rotation of the boom at the desired angle with respect to the base by means known in themselves power components, such as cylinder pressure, or something similar.
The boom 4 is equipped with the rotatable together with the cradle 5, which, in turn, are equipped with a feed beam 6 having the ability to move in the longitudinal napravleniyami beam 6 can be moved relative to the tray support 5 known per se manner by means of the cylinder 6A with the medium under pressure. The feed beam 6 is known in itself by the way equipped with a hammer, not shown, for drilling through a drill stem, and, in General, known drill bit that is attached to it. Feed the timber and the hammer and part of the drill stem is surrounded by a housing 7 for sound attenuation. The drill end of the feed beam 6, that is, in the end, through which the push drilling drill bit and drill rod, is an additional protective part 8, which will be described in more detail in the context of figure 2.
The figure 2 presents a more detailed schematic side view of a variant of implementation of the construction of the protective part 8. The lower end of the housing 7 for sound attenuation, i.e. the drill head feed beam contains as of the end of the housing for damping sound of the first protective portion 7a of the protective device having a hole for the drill bit and drill rod. Protective part 8, as the second protective part, contains the suction nozzle 9, is designed for suction of dust and, on the other hand, for sound attenuation, while in the process of drilling suction nozzle must be pressed to the surface of the soil or rock. The edge of the suction nozzle 9 preferably contains edge seal 9a made of flexible material and passing around the edge of the ICA is yvouxeo nozzle, this edge seal pliable and when the pressure is in accordance with the surface of the soil or rock, while providing the most possible sealed position. In addition, the protective part 8 comprises a tubular part 10 and the suction nozzle 11, attached to it. Between the tubular part 10 and the housing 7 for sound attenuation is the bellows 12, used as a flexible protective element, which is tightly fixed at its ends to the ends of the housing for damping sound on one side and to the tubular part 10 of the suction nozzle with the other hand. There is an open connection from the suction nozzle 9 through the tubular part 10 and, respectively, of the housing for damping sound through the bellows 12 to the suction pipe 11, through which the waste during drilling, separated from probatively well, with the aim of disposal will be otkazyvatsa exhaust fan, which is in itself known, but not shown. Such solutions in the form of a device for sucking off dust and waste generated during drilling, in themselves known, and since they don't actually relate to the present invention, there is no need for more detailed clarification.
