    [0001] PROCEDURE FOR CLEANING OF IN SITU AND USEFUL EXTRACTION SHRUBS
    [0002]
    [0003]
    [0004]
    [0005] OBJECT OF THE INVENTION
    [0006]
    [0007] The present invention relates to a method for cleaning shrubs in situ, that is, in mountains and pastures, and to an extraction tool specifically used for said process. It fits into the technical sector of forest cleaning for energy use.
    [0008]
    [0009] BACKGROUND OF THE INVENTION
    [0010]
    [0011] Currently it is considered unviable to clean bushes (broom, broom, heather, juniper, boxwood, etc.) in mountain ranges, mountains, pastures, etc. because of the high economic cost that these jobs represent, since these bushes have no industrial application or energy use, which added to the difficulty in felling, transport and stocking due to its high branching and space occupation -most of the even being empty - prevents its profitability. Its elimination, in addition, with current means implies the use of chain cutters that what they do is spread the clearing and forces a subsequent collection, manual or mechanized that increases the costs. On the other hand these brushcutters do not produce clean cuts and leave open stems, and if you try to lower the height of the debris erode the terrain and shorten the life of the chains.
    [0012]
    [0013] For these reasons the cleaning of these shrubs of mountains and pastures has been abandoned, being a necessity as much for the feeding of cattle as for the prevention of fires.
    [0014]
    [0015] These works could only be carried out if the State took charge of them, or making the product (biomass) that is obtained profitable. Of course, currently a lot of biomass is obtained from our forests but it does not come from the scrub, the difficulties enunciated and why its combustion poses for its high content of chlorine and moisture, which is why many thousands of hectares of these thickets that exist in our country are wasted, even more so when it can generate a profitable synergy, such as cleaning These thickets of our natural spaces.
    [0016]
    [0017] DESCRIPTION OF THE INVENTION
    [0018]
    [0019] The procedure for cleaning shrubs in situ of the invention comprises the steps of: - performing, by means of pre-hugging, the extraction of the bushes by means of an extraction tool that is mounted on a self-propelled machine, and carrying the bushes for chopping,
    [0020] -pick in situ the shrubs extracted by means of a chopper to reduce its size and increase its material compaction, and
    [0021] -transport to storage or point of consumption.
    [0022]
    [0023] The tool of the invention, on the other hand, comprises:
    [0024] a clamp provided with arms and means for opening and closing said arms, for holding the bush or shrubs for extraction, and
    [0025] -a fixing anchor to a self-propelled machine.
    [0026]
    [0027] In this way, the tool not only starts or cuts the bush or shrubs, but also extracts and carries in piles or rows for immediate processing (chopped) in situ or even deposits directly into the chopper, for once reduced its size, transport it easily from the bush or pasture. Subsequently, the product can be marketed as biomass, which can be burned for energy use in boilers suitable for combustion of fuels with high chlorine content, typically industrial boilers, to obtain heat or hot water or steam to generate electricity directly or with cogeneration.
    [0028]
    [0029] With the method and tool of the invention, the following advantages are obtained:
    [0030] -cleaning of the mountain, with which we obtain greater spaces for cattle grazing and corresponding subsidies,
    [0031] -prevention and better action against fires, as well as the economic saving of public money that supposes in costs of extinction of the fires that are avoided,
    [0032] - reduce pollutant emissions (carbon monoxide, etc.) of industries by consuming biomass with respect to the consumption of fossil fuels (gas oil, gas), and therefore greater environmental balance, contributing to improve the decline of global warming, lower the price of electricity if we produce electricity, lower costs in fuel consumption (from 30 to 60%) improving the competitiveness of the products,
    [0033] -balance costs in the production of this biomass with respect to others.
    [0034] -provide work in rural areas.
    [0035] -high profitability when joining the mechanization of the forest cleaning of the system with the profitability produced of this biomass before the current fuels.
    [0036]
    [0037] Another advantage of the tool of the invention is that, in places where it allows, either by the slope of the ground, the density of the bushes or even the diameter of the trunk of the same, these can be started with the single embrace of the scrub and then pulled upwards without the need for blade action. The cattle ranchers prefer the uprooted because there is no trunk on the ground subject to the ground, with which the cattle and people trip when they handle them; Likewise, many lesions in the hooves of the cows produced by these trunks when they are stuck between them are avoided.

    [0046]
    [0047] PREFERRED EMBODIMENT OF THE INVENTION
    [0048]
    [0049] The method for cleaning bushes (1) in situ of the invention comprises the steps of (see fig 1):
    [0050] -Make, by means of a previous embrace, the extraction of the bushes (1) by means of a tool (2) of extraction that is mounted on a self-propelled machine (3), and hauling, by means of said machine (3) ideally for saving on machinery, the bushes (1) for chopping,
    [0051] -pick in situ the bushes (1) extracted by chopper (19) to reduce its size and increase its material compaction, and
    [0052] -transport to storage or point of consumption.
    [0053]
    [0054] Subsequently, the product can be marketed as biomass that can be burned for energy use in boilers suitable for combustion of fuels with high chlorine content, typically industrial boilers where the metal walls are replaced by refractory brick walls to prevent corrosion due to combustion in the presence of chlorine, to obtain heat or hot water or steam to generate electricity directly or with cogeneration.
    [0055]
    [0056] Preferably the chopping will be sized for a minimum production of 30 tons per hour, since in the profitability tests performed the most reasonable benefits have been obtained from this volume of processing.
    [0057]
    [0058] Ideally, the transfer of the chopped product (20) for storage is carried out in trailers (4) pulled by agricultural tractor (5), since they will frequently be the only vehicles that will be able to access the extraction and chopping site (the mountain or pastures, many sometimes in heights or accessible by little practicable roads). This way of proceeding makes cheaper the production costs of this biomass compared to biomasses from other sources.
    [0059]
    [0060] Furthermore, the self-propelled machine (3) preferably comprises a machine of 2000 kilos, in order to carry a tool (2) with sufficient dimensions without penalizing its ability to access the work site due to excess size.
    [0061]
    [0062] Specifically, the extraction tool (2) for the process for cleaning bushes (1) in situ of the invention comprises (see figs 2 and 3):
    [0063] - a clamp (6) provided with arms (7a, 7b) and means for opening and closing said arms (7a, 7b), for hugging the bush (1) or bushes for extraction,
    [0064] - an anchor (9) for attachment to a self-propelled machine (3).
    [0065] Very preferably the clamp (6) comprises a central base (10) in which the anchor (9) is arranged, and two lateral arms (7a, 7b) provided with first vertical joints (11) for joining said base (10). ); comprising means for actuating said arms (7a, 7b) in opening and closing, since in this way a reduced number of arms (7a, 7b) of reduced length is achieved. The means for actuating the arms (7a, 7b) comprise a first hydraulic cylinder (12) (see fig 2) which is connected at one of its ends to the first joint (11) of the first arm (7a) and by the another end to the second arm (7b) opposite by means of a second articulation (14) eccentric with respect to the first articulation (11) of said second arm (7b); comprising a connecting rod (18) (see also fig 3) which is connecting said second joint (14) with a third joint (17) of the first arm (7a), eccentric with respect to the first joint (11) of said first arm ( 7a), so that when the first cylinder (12) is actuated, the simultaneous rotation of the arms (7a, 7b) occurs around its first joints (11).
    [0066]
    [0067] Additionally, the tool (2) may comprise a lower cutting blade (8) of the stem of said bush (1) or bushes that acts in coordination with the clamp (6). Said blade (8) is preferably disposed inferiorly flush with the clamp (6), since in this way it has a certain shearing effect that improves the effectiveness of the cut and minimizes the stripping. The blade (8) can be fixed and projected towards the zone of action of the clamp (6), so that when closing said clamp (6) press the bushes (1) against the blade (8) to make the cut. Alternatively, said blade (8) can be fixed to the base (10) through a fourth lateral articulation (15), comprising advance means of the blade (8) by turning it around said fourth articulation (15) to run under the clamp that holds the bush (1) or shrubs and section all its stem or stems.
    [0068]
    [0069] The advancing means of the blade (8) normally comprise a second hydraulic cylinder (16) (see fig 2) attached at one end to the base (10) and at the end opposite the blade (8).
    [0070]
    [0071] To increase the profitability of the process, it will be convenient to have adequate investment in both machinery and personnel to obtain the biomass, and have a commercial network for the sale of the boilers and the installation, feeding, and maintenance of the boilers.
    [0072]
    [0073] The nature of the invention being sufficiently described, it is indicated that the description thereof and its preferred embodiment must be interpreted in a non-limiting manner, and that it encompasses all of the possible variants of embodiment that are deduced from the content of the present specification. and of the claims.
