Description

Machine to distribute and level paving materials.

Technical sector

The present invention is related to the arrangement of the materials that extend to pave any type of surface, proposing a self-propelled machine of reduced dimensions and weight, with which you can work in places of little extension

State of the art

The extent of the materials, such as sand, concrete, etc., which They are used in paving and / or surface construction, perform manually or using specially designed machines and  Ready for that function.

The use of machines in that need implies a considerable savings in labor and time, which affects definitive in an economic advantage of the cost of execution; but with currently existing machines it is only possible to operate in large places, so that in places of space reduced, such as basement floors, decks and construction platforms, etc., the work must be done manually, with all inconveniences of difficulty, time and cost that this implies.

Object of the invention

In accordance with the present invention a machine is proposed that works in a self-propelled way and that is formed according to a structural realization of reduced dimensions and weight, resulting suitable for working in places of little space, with respect to those It can also be incorporated and removed very easily.

This machine object of the invention consists of a chassis that goes incorporated with respect to three rolling bearings provided with respective drive motorizations, being one of the Actable braces in orientation while at one end of the chassis incorporates a head of action on the material to extend, which is supported by active supports of height adjustment, going all the related functional set with a government team that is remotely commandable for the functioning.

The distribution of the rolling bearings determines a large machine movement maneuverability, with each support with a pair of parallel wheels, which determines a large weight load distribution, allowing operation on surfaces not consistent

The wheels of the supports are incorporated by means of a support tilting, allowing to absorb the irregularities of the displacement surface without affecting the work of the machine.

The wheels of the adjustable support are also arranged in a height-adjustable support, which allows the position to be adapted of the machine depending on the deformations that the operating surface

The head support supports are related to proximity detectors with respect to the work surface, what which determines an automatic positioning of the head in the height and inclination corresponding to the surface of application.

Both the head assembly and the wheels located more towards The outside on the sides of the machine, are easily removable, being able to be incorporated on the rest of the set of the machine, in an arrangement that further reduces the dimensions for storage and transport.

Therefore, said machine object of the invention is certainly of very advantageous characteristics, acquiring own life and preferential character for the function to which it is destined.

Detailed description of the invention

The object of the invention relates to a machine intended to distribute paving materials on surfaces corresponding, so that, by its characteristics, this machine is suitable for working in places of reduced space, where conventional machines of the same function cannot operate.

The recommended machine consists of a structural chassis (1), which It is arranged on a support of three rolling supports, two of which are formed by wheels (2 and 3) of orientation fixed, while the third support is formed by wheels (4) of variable orientation

This results in a machine assembly that can maneuver in very little space, composing the supports by pairs of corresponding parallel wheels (2, 3 and 4), among which determine a distribution of the weight load that makes reduced the incidence at each support point, allowing to operate on relatively soft surfaces, such as dirt, sand, concrete cool, etc.

The pairs of wheels (2, 3 and 4) that form the supports go arranged in axes incorporated on corresponding hydraulic motor-reducers (5), so that the set of machine support is provided with all-wheel drive, facilitating movements; while through mentioned motor-reducers (5) the pairs of wheels (2, 3 and 4) they remain in a tilting assembly, facilitating the support on irregular surfaces.

The pairs of wheels (2 and 3) of fixed orientation are arranged parallel to the front of the machine while the pair of wheels (4) of variable orientation goes individually in the rear, this pair of wheels (4) being arranged in relationship with a vertical axis (6) that allows the orientation rotation by means of lateral actuator cylinders (7) and also in mounting by means of a support (8) of vertical regulation that allows vary the height

On the front of the machine is incorporated supported by the chassis (1) a head (9) transversely arranged, along of which are included an endless distributor (10), a leveling auger  (11) and a vibrator (12), which are the organs responsible for make a uniformly flush distribution of materials of application on the corresponding surfaces.

The head (9) is supported by vertical cylinders (13), which allow varying the height and inclination of the mentioned head (9) to keep it parallel to the surface of application. To do this at the bottom of the head (9) go arranged proximity detectors (not shown) with respect to to the work surface, in relation to which cylinders (13) have receivers (14) that act the actuation of said cylinders (13) depending on the signals of the above mentioned proximity detectors for  position the head (9) properly with respect to the work surface.

The entire functional set of the machine is controlled by a government team (15), which is likely to be commanded to distance, either by means of a wave communication control radio, or through a cable, so that the machine can be governed without any operator having to go over it, avoiding with it the human accidents.

Under these conditions the machine can be placed by means of a crane anywhere where your intervention is required, such as they can be the elevated and covered work platforms in the constructions, or in underground plants, to carry out the jobs required by a remote control with the remote corresponding distance, since through the equipment (15) the machine receives the orders that are transmitted to it and is activated to Take them to effect.

Solidarity to the chassis (1) some hooks are provided (16), in respect of which the subjection with chains, cables, or similar means, for lifting the machine in their incorporation and withdrawal from workplaces.

The wheels on the outside of the wheel pairs (2 and 3) Fixed orientation, they are easily removable, just as the head (9), so that said outer wheels (2 and 3) and the head (9) can be disassembled and placed on the rest of the machine assembly, as shown in figures 4 and 5, with what which is obtained a very small disposition of the machine, in a position that is advantageous for storage and transport.
