At the other end of the shaft (4) there is an air turbine (6) located in a housing, to which the first pneumatic conduit (7) connected to the first valve (8) is connected. A nozzle (9) is attached to the pin (1) near the working head (2), directed towards the end of the working head (2) and connected to the second valve (11) with a second pneumatic conduit (10).

Description

Description of the invention

The subject of the invention is a pneumatic device for removing paving stones.

So far, a pneumatic hammer is known from the SU53420A1 patent application, which uses the energy of compressed air to drive the piston, setting it in motion and thus driving the working tool that hits the workpiece.

So far, a manual gripper (imak) for removing paving stones is known from the PPU Imal catalog. It has blades that, using physical force, are inserted between the elements of the paving surface in order to extract a single element.

However, from the catalog of Jazon Sp. z o. o. There is a well-known paving balancer that has a single blade that is inserted into the paving surface by the physical force of the operator in order to remove individual elements.

The technical problem to be solved is the need to easily remove paving surface elements, without the need to use excessive human force or damage the paving surface elements.

The subject of the invention is a pneumatic device for removing paving stones, having a pin with a handle at the first end and a working head at the other end. Its essence is that the handle is attached to the shaft with a vibration damper. There is a hole in the shaft perpendicular to its axis, in which there is a shaft with a vibrating mass at the first end. At the other end of the shaft there is an air turbine located in a housing, to which the first pneumatic conduit connected to the first valve is connected. A nozzle is attached to the pin near the working head, directed towards the end of the working head and connected to the second valve via a second pneumatic line.

A beneficial effect of the invention is that the removal of paving surface elements will become easier and, as a result, the times of renovation and paving works will be shortened.

The subject of the invention in an embodiment is shown in the drawing, in which the individual figures show:

Fig. 1 - perspective view of the device, Fig. 2 - side view of the device, Fig. 3 - device in cross-section along line A-A.

The subject of the invention in the form of a pneumatic device for removing paving stones has a pin 1, at the first end of which there is a handle 1.1, and at the other end a working head 2. The handle 1.1 is attached to the pin 1 by means of a vibration damper 3. In the pin 1 there is a hole 1.2 arranged perpendicular to its axis, in which there is a shaft 4, at the first end of which there is a vibrating mass 5. At the other end of the shaft 4 there is an air turbine 6 located in a housing to which the first pneumatic conduit 7 is connected connected to the first valve 8. A nozzle 9 is attached to the pin 1 near the working head 2, directed towards the end of the working head 2 and connected to the second valve 11 with a second pneumatic conduit 10.

The operation of the device is based on the fact that compressed air supplied through the first valve 8 and the first pneumatic conduit 7 to the air turbine 6 causes it to rotate, generating a torque which, via the shaft 4, sets the vibrating mass 5 in rotation. The mass generates an undirected vibrating movement of the spindle 1 and the working head 2, which, placed between the elements of the paving surface, causes their movement and thus enables their extraction from the paving surface. At the same time, the operator, using the second pneumatic valve 11 controlling the nozzle, can control the supply of compressed air through the second pneumatic conduit 10 to the nozzle 9, which is directed towards the working head 2. The compressed air stream is intended to remove loose particles of aggregate and dirt located in free spaces. between individual elements of the paving surface. In order to protect the operator against the adverse effects of device vibrations, the pin 1 is separated from the handle 1.1 by a vibration damper 3.
