FOREST

OBJECT OF THE INVENTION

The present invention refers to a new crushing machine for agricultural and / or forestry use for the crushing of materials deposited in the non-rooted soil such as branches, pruning remains or the like, which also has the particularity that structurally it can be disassembled into two different modules easily and quickly, so that one of the modules or equipment of the machine of the invention can function independently as a floor crusher for less demanding or less fine crushing.

For this, the feeding grinding machine of the invention comprises a feeding module or equipment on which a grinding module or equipment is secured by mechanical fixing means; where the feeding equipment comprises a rigid frame formed by vertical side plates where there are sockets for coupling with the crushing equipment, a screen with counter-blades that forms a crushing cavity and a counter-comb grid distributed between the gaps of some tines of a feeder rotor, and this feeder equipment also comprises the aforementioned feeder rotor with tines secured at two opposite ends of the rigid frame, which is driven by a hydraulic motor with which it connects, and height-adjustable wheels located on the sides rigid frame; and where the crushing equipment comprises a main frame where all the components of the equipment are secured, such that articulated rear side covers that support a roller and are driven by at least one hydraulic cylinder, a crusher rotor with blades or hammers in connection with mechanical means of actuation, a curtain of protection plates and a head.

The field of application of the invention is included within the sector of the manufacture and marketing of agricultural machinery Feeder shredder that is modular and convertible into a floor stand shredder.

BACKGROUND OF THE INVENTION

At present there are several types of horizontal axis agricultural and forestry shredders that can be classified into two groups depending on the application required by the user. These two groups of crushers are known as underfloor crushers and fed crushers.

The work carried out by the floor crushers is to crush material that does not require a very fine or rigorous finish. This is the case, for example, of the crushing of herbs, shrubs, weeds or similar, where what is sought is a non-specific crushing without a specific requirement in the crushing. On the contrary, the work carried out by the feeder crushers is a much more specific type of crushing than in the previous case, where the aim is to obtain a very fine finish of material deposited on the ground, as is the case of the crushing of branches, pruning remains or similar.

Well, with the feeder crushing machine object of the present invention both feed crushing and ground crushing are achieved by means of a single machine, which is made up of two independent structural equipment that can be coupled and uncoupled. For this, the machine as a whole is made up of a feeder equipment on which a shredding equipment anchors, so that with this connection both equipment are structurally complemented to carry out the crushing of branches, pruning remains or similar; Whereas when both units are uncoupled through their respective sockets located in each of their frames, the crushing equipment of the machine of the invention can independently carry out the crushing of herbs, shrubs, weeds or the like.

Therefore, with the proposed object of the present invention, it is possible to combine two different types of shredding with a single machine, so that this convergence of functionalities gives the whole machine a great flexibility. At the same time, it provides the associated advantage of reducing structural costs to a company or user, who to date has required the purchase of at least two machines to carry out two different types of crushing, than with the machine of the The invention is solved with the purchase or acquisition of a single machine, which performs both a fed-type crushing and a counter-ground type crushing, through the coupling or uncoupling of two independent mechanical equipment.

Thus, the structural configuration of the feeder crushing machine for agricultural and forestry works object of the present invention is constituted by a modular structure that improves the versatility of the crushing machines known to date in this sector.

The following is a detailed description of the invention that completes these general ideas introduced at this point.

DESCRIPTION OF THE INVENTION

The feeder grinding machine object of the present invention comprises a feeder equipment located in the lower part of the machine on which a grinding equipment is fixed by mechanical means through sockets located in their respective frames. So, the feeding equipment comprises a rigid frame where a feeder rotor with tines in connection with a hydraulic motor and height-adjustable wheels is secured, so that this rigid frame in turn comprises vertical side plates with fittings, a screen with counter knives and a counter-comb screen; and where the crushing equipment comprises a main frame where all the components of the equipment are secured, articulated rear side covers that support a roller and that are driven by at least one hydraulic cylinder, a crusher rotor with blades or hammers in connection with some mechanical means of actuation, a curtain of protection plates and a head.

As previously mentioned, the structural assembly of the machine of the invention is formed by the coupling or assembly of the crushing equipment on the feeding equipment through some sockets located in their respective frames. Specifically, the main frame of the grinding equipment has a preferably tongue and groove type fitting on its main frame, while the feeding equipment has an homologous fitting located on vertical side plates of its rigid frame. So that once both frames are anchored by their sockets, they are also fixed by mechanical means, preferably bolts and screws. So as a whole, the machine of the invention is constituted by the union of both equipments or modules, which in combination act as a feeder crushing machine for agricultural and forestry work. Another detail of the invention is that both equipment can also be separated and the crushing equipment can act as a floor crusher.

The feeding equipment that makes up the lower part of the machine of the invention on which the grinding equipment is attached, is made up of a rigid frame that is formed by vertical side plates that provide rigidity to the assembly and is where some fittings are located where coupling occurs; a screen that forms a crushing cavity and has a plurality of counter knives distributed along its surface; and a lattice or a counter-comb grating, where each of the counter-combs is distributed between each of the gaps of some tines of a feeder rotor. The feeding equipment also comprises the aforementioned feeder rotor with tines that is secured at two opposite ends of the rigid frame and is driven by a hydraulic motor with which it connects, this hydraulic motor being in connection with the hydraulic circuit of the tractor or carrier vehicle that moves the whole machine along agricultural or forest land; and some wheels located on the sides of the rigid frame that are adjustable in height and achieve a correct support for the entire team on the ground.

For its part, the crushing equipment of the machine of the invention forms the upper module of the machine and comprises a main frame, which has the function of supporting all the components of the equipment and offering structural rigidity to withstand all related loads and stresses. with crushing work; hinged rear covers on each side of the main frame, between which a roller is supported, and are foldable by the action of at least one hydraulic cylinder; a grinding rotor that is secured by its ends to the main frame acting as a cutting tool, and is formed by a tube with lugs attached to the rotation of the rotor and where knives or hammers are anchored; this crushing rotor is in connection with mechanical drive means comprising a kinematic chain formed by a multiplier box with a lateral extension, a set of lateral belts and pulleys and pockets that house bearings; and a curtain of protection plates secured in the front part of the main frame that avoids projections to the outside during the crushing of the material.

For all these reasons, once each of the components that make up both the feeding equipment and the grinding equipment that make up the feeding grinding machine of the invention have been described, the operation of the set is described below.

In accordance with the foregoing, when the feeder crushing machine is working, the side covers of the crushing equipment are raised or open and the roller acts as a pusher for the weed, of the type of branches, pruning debris or similar, and for this the machine of the invention is moved in reverse by the carrier vehicle or the like. In this case, the tine feeder rotor lifts the branches from the ground and leads them to the crushing cavity, formed by the screen with the counter blades of the feeding equipment and by the crushing rotor with the blades or hammers of the crushing equipment. Thus, while the material is shredded by the crushing rotor, the counter knives retain the branches in the crushing cavity, improving this chopping until the material reaches a specific measure and passes through the holes in the screen.

As previously mentioned, another detail of the invention is that the equipment that makes up the machine can be separated, so that the crushing equipment can work independently as a floor crusher. In this case, the crushing equipment works with the lids lowered or closed, so that the roller remains on the ground acting as a point of support. In this case, the whole of the crushing equipment is moved forward by a carrier vehicle or the like and the material to be crushed, such as herbs, shrubs or the like, passes through the protection plate to the crusher rotor where it is directly crushed.

Therefore, the crushing machine of the invention has a structural configuration according to a feeding equipment and a crushing equipment, which gives the assembly great flexibility. Thus, the convergence of functionalities of the machine of the invention gives the set great versatility and at the same time considerably reduces the structural costs of manufacture and acquisition, since with a single machine two different types of crushing can be carried out depending on whether the machine operates with its two assembled equipment, or if the machine operates only with the shredder equipment. Specifying that both the assembly and disassembly of both equipment is carried out by means of the action of a tractor or similar, without the need for additional elements or vehicles.
