Description

MULTIFUNCTIONAL PORTABLE CONCRETE

OBJECT OF THE INVENTION

The present invention relates to a multifunctional portable honnigonera, which also has the characteristic of being removable and being constituted in a very light structure.

The object of the invention is to provide certain construction professionals, as well as certain fans of small repairs, a sling that is very light and can be transported from one place to another without any problem, being removable and offering the possibility of multiple uses.

BACKGROUND OF THE INVENTION

A good number of professionals of the small reform, usually do their work without using a slinging, since it is extremely heavy, cumbersome to store and transport, to which we must add the impossibility of raising it in elevators to the floors, regardless of the operation is noisy, and that the machine is uncomfortable to clean.

In short, the use of concrete mixers in small works what it does is complicate the professional rather than help you, so many

Small reform professionals end up kneading cement, either by hand or with beater accessories, initially designed for mixing paints, connected to a hand-held drilling machine.

Any of these jobs, in addition to being heavy and tedious, produces low quality mixtures, little homogenization, and requires an operator, who could devote himself to much more productive purposes during the eight or ten minutes necessary to properly mix each bucket that You want to beat.

There is an additional problem posed by conventional honnigoneras, and is that of its use in remote places until where the electricity supply does not reach, such as orchards, stables, fences of farms and others, so that in these cases the concrete mixers usually go equipped with a gasoline explosion engine, instead of the usual electric to motorize them, this solution is more expensive and unapproachable even for the amateur, and even for the professional of small reforms, which makes the machine heavier and difficult to store, if possible .

There are also people who are very fond of DIY and even small refonnas, and even living on farms, in single-family homes, etc., they do not usually have slingers, because it is not interesting the inconvenience of storing a sling in a storage room or garage in front of its use two or three times a year.

However, there is news of the existence of relatively light and economical honnigoneras for use by the amateur or the small builder, based on fully or partially removable or foldable supports and with the removable bowl for a lower occupation in its storage / transport, although in none of the cases there is reference that the tank has been designed to provide any other service other than kneading mortar once it has been decoupled from its support / engine system.

However, despite the fact that portable and relatively lightweight sling models are offered, however they are bulky and certainly heavy.

On the other hand, honnigoneras with the plastic tank are known, but in no case nor is their tank stackable with other containers to minimize their occupation in transport and storage, a very important objective with a view to reducing the cost of supply to the public, neither the tank is usable as a container in which the operator can transport and use the dough, nor is it intended to be used for purposes other than l. mortar making.

Mixers of fine granulometry material are also known, whose mixing vessel is a bucket or carrycot very similar to conventional ones, but where the tank is not rotary but stationary, the vanes being the ones that rotate and although a possible use for mixing cement, it is considered that they do not perform this function optimally as a mixer based on a rotating bowl, as a conventional honnigoneras.

Nor are portable concrete mixers known for mixing machines that can be operated by crank, which would be very useful in certain work situations.

DESCRIPTION OF THE INVENTION

The honnigonera that is recommended has been conceived to solve the previously exposed problem, since on the one hand the total set of the concrete mixer is extremely small, being able to estimate that in its fully folded position, that is, when it is not in use, the Honnigonera can occupy a volumetry of 60 x 50 x 20 cm.

More specifically, the honnigonera of the invention is constituted from a vat that is rotatable and inside it incorporates the corresponding paddles for the homogeneous kneading of the mortar, with the particularity that said vat, as a heavier and bulky element in a concrete mixer Conventional, it is conceived in the invention to be usable for other purposes, when it is disassembled from the concrete mixer assembly or support, so that the tank is complemented by an upper closing dome provided with a loading mouth, and whose dome is fixed to the tank with the interposition of a joint of henoethicity, by means of springs type "clip" that anchors the whole of the tank with the dome and with a lower support plate of the tank itself, which is linked, on each side, the spring type "clip" and is related to the upper closing dome, also having rings on two of the opposite sides, to close the tank and dome assembly in its use ind ependiente regarding the set that supports the support of the honorary woman proper.

The support is constituted by lower support legs, which form on each side a kind of angles with lateral plates in support functions proper, in such a way that through anchoring screws the anchoring of the lateral support plates to the corresponding support legs, being also mounted on the lateral support plates, an arm on which the tank rotated by

a motor, with gearbox, and whose arm is articulated by its

ends, or what is the same is rotating through its ends, on the

lateral supports, so that in combination with a lever it can be carried

make the inclination to a greater or lesser extent of the tank, to obtain the

suitable angle for the shake or for any eventuality that is required.

There is a tilt shaft crown, which locks in a

position determined by means of a ratchet that acts in functions of

locking clamp on the commented crown.

use the tank as a conventional spur or carrycot, so that

it will be constituted in a semi-rigid or rubbery plastic material, of the type of

which are commonly used in masonry to transport and contain the

already beaten cement to be applied, forming the dome a

stamped steel sheet with rubber gasket to provide tightness to the

fixation that is made on the lower support plate, which is rotary and will be

propelled by the engine mentioned above.

On the other hand, the milkshakes paddles established in the interior of the assembly of the honnigonera, are solidly seated in welded housings inside the dome, being removable to minimize the size of the assembly once in disuse and folding.

The elements that make up the drum or vat, once washed at

At the end of the work, they can be used on a regular and daily basis, together or separately, for completely different purposes than those of kneading mortar, once they are no longer required.

The spur that constitutes the Cuba can be used for all

uses to which a common door is dedicated, and even as a container for

garbage to sweep the garden or for workshop waste in case of use by

construction professionals, as well as to transport aggregates or

debris, and in general for all purposes for which carrycotts are used and

spurs.

On the other hand, the truncated dome will be complemented with a lid associated with a hennetic seal, hanging the whole of the tank with the dome serving as a bucket of organic waste that can emanate odors, as well as to store in humid environments (basement, sheds and others), tools or products to be protected, and for all imaginable purposes to which a container or light drum can be dedicated, with anchors, airtight and even aesthetic and innovative so that the lid that seals the loading mouth it can be used either with the rubber gasket attached to provide henneticity to the container, or without it in case a frequent and non-hennetic rapid opening / closing is needed, for example, as a workshop bin, as a laundry container, or as a contender for

recyclable

It is intended that the usual mode of work with the honnigonera referred to is not using a single tank, but two, since in the first place it is a very economical material to acquire and it is also stackable in storage with other analogues, so that although the

volume of each kneading is not too large, when removing a bowl of pasta prepared for use, another is left beating in the meantime, this operation is very simple and quick to perform by releasing the perimeter clip springs that fix the bowl to the plate bottom support.

It has already been said that the Cuba will preferably be constituted in

a plastic material, which can be an ordinary and economical plastic or

be of a rubbery plastic material, the type of those currently used in

buckets dedicated to construction, of very high durability and resistance to

abrasion, although it is somewhat heavier and slightly more expensive, suitable for

its daily and intensive use by the construction professional, being able to be carried out, alternatively in a plastic for food use

for possible use in the mixing and agitation of products by the food, catering or hospitality kitchen industry, of

so that to cover this last case you can manufacture and offer dome and

kneading paddles in food grade stainless steel.

As for the gearbox associated with the drive motor, a drive cam from the outside is provided therein which will act by separating one of the gears that foon an inner cascade of cogwheels coming from the engine, in order to disengage it from the same and approaching it, in the same movement, until clutch it to another cogwheel that, in turn, teonina in an output shaft outside the box, for the insertion of the already mentioned hand-operated crank. The

commented cam serves in turn to block access to the axis where the

crank, when its position is required to obtain traction from the engine, for safety reasons.

Finally, it is planned that the concrete mixer assembly can be housed in a flattened bag of orthopedic general configuration, for storage and transport, and whose bag will be made of a resistant plastic textile material and will have a belt or strap to transport it easily hanging from the shoulder.

The tank (1) is mounted on a plate (4) as an element of

lift, fixing it by means of springs (5) clip type, which

They extend from the plate (4), in correspondence with each of the sides of the tank, to the dome (2), there are some rings (6) to close the whole of the tank (1) with the dome (2) in its independent use.

The tank (1) in its assembly on the plate (4) is rotatable on an axis (7), that axis is driven by means of a motor-reducer (8) or a gearbox (9), which can be the drive by means of a crank that can be coupled on a shaft (10) established in combination with a cam on the gearbox (9) for rotating operation of the tank (1).

On the other hand, a tilt or tilt arm of the tank (1) is provided, in order to obtain a suitable angle for the shake, an arm that is referenced with the number (11) And that is mounted through its ends on pivot shafts (12) established in lateral supports (13) related to support and support legs (14), so that the supports (13) are fixed to the legs (14) by means of clamping screws (15) ), with the particular feature that the corresponding crown of the tilt axis of the tank (1), and therefore of tilting the arm (11), is capable of being locked by means of a ratchet (16), the assembly being activated to achieve one inclination or the other by means of a lever (17), interlockable on some lugs (19) provided precisely in the inclination arm (11), lever (17) that could also be operated with the foot, according

with another position that could occupy with respect to the general support of

support of the tank (1) of the concrete mixer.

It is also provided that the tank (1) has the corresponding handles (18), to allow its manual manipulation by the user.

The tank (1) will be reinforced with vertical and outer lateral ribs, materialized as already said, in an appropriate plastic, while the components that constitute the support and support legs (14), the tilt arm (11) and the lever (17), will be materialized in steel or even aluminum sheet tube, being shaped by bending in the usual way in the industry.

On the other hand, the lateral supports (13) will be constituted by

identical semi-bodies, facing each other and materialized in sheet steel

sausage.

The dome will also be made of steel sheet

(2) and the support plate (4), the first one equipped with a rubber gasket in a petimetral groove intended to house it.
