Description

Scissor cutting shear.

The present invention, which is intended to protect as a utility model, it refers to a cutting shear by scissors applicable to a compacting or packing apparatus biomass

Background of the invention

The compaction or packing of biomass is used to reduce forest waste by 80% produced after logging of forests, as they can be small trunks, branches, shrubs and barks that fall into the category of biomass With the collection of this waste a double is achieved benefit: on the one hand, energy production and, on the other, its removal of forests, which significantly reduces the risks of fires

The cutting elements, intended for the Bales of biomass, are located in the final part of the baler

There are currently various types of devices destined to the cut of biomass, but, in general, they present a system by gouge cutting chain. These systems are little effective and durable, since the wear of the chains causes the breaking them with relative frequency.

The present invention of cutting shear by scissors, applicable to a compacting or packing apparatus biomass, presents different advantages with respect to existing devices It produces a cleaner cut of the bale, it requires less maintenance and is more robust, which reduces breakdowns, with consequent cost reductions and increases of productivity.

Therefore, scissor cutting shears a new more advantageous alternative with respect to the mechanisms Up to now existing destined to the cut of bales of biomass.

Description of the invention

The present invention relates to a shear cutting applicable to a compacting or packing machine biomass, which consists essentially of a structure or chassis; two knife holders, where two blades are mounted; two hydraulic cylinders, and optionally, anchored to the structure,  a funnel to facilitate the entry of the bale of biomass, as well as its focused to get a more effective cut.

The knife holders are mounted on blades, which are the ones that cut the bale. These blades can be fixed or interchangeable; in this last Of course, they are screwed to two knife holders.

The two knife holders can be symmetrical, in whose case are mounted on two different planes and move with respect to a fixed point common to both, or they may not be symmetrical, in whose assumption are mounted on the same plane and move with respect to a fixed point that is not coincident in both.

The knife holders, in addition to having a fixed axis turn, which may or may not be the same for both knife holder, they have another axis of mobile rotation and they go articulated hydraulic cylinders that are responsible for move the knife holders and, therefore, perform the force necessary for the cut to occur. When the cylinder is closed, the blades separate and allow the bale to pass. Subsequently, the cylinders open to section the bale to the desired length

The cylinders are placed horizontally in the top of the shear and are attached to the chassis, of so that the efforts are absorbed by this element structural.

The cutting shear of biomass by scissors, applicable to a compacting or packing apparatus, represents a innovative realization with technical and structural characteristics not described so far in shear systems, which means a new contribution to the state of the art so far known.

Description of the drawings

To better understand what concerns us, we several figures corresponding to two embodiments are attached Preferred scissor cutting shears, one corresponding to one shear cutting by scissors of common fixed axis, and the other of scissor cutting shears with fixed double shaft.

The accompanying drawings have a character merely indicative and not limiting and in them it has been represented the next:

Figure 1 shows a perspective view of a preferred embodiment of the present invention consisting of a shear of cut by scissors of fixed fixed axis.

Figure 2 shows a perspective view of the common fixed shaft scissors cutting shear without the chassis or structure.

Figure 3 shows a front view of the set of blades, blades and cylinders belonging to the shear cutter by common fixed axis scissors.

Detailed description of a preferred embodiment

To help you better understand everything described previously, an embodiment is described below Preferred invention (see figures 1 to 4), which corresponds to a common fixed axis scissor cutting shear which comprises the parts and elements that are indicated and described in detail act Following.

This embodiment is essentially constituted by a structure or chassis (1) that absorbs cutting forces and allows, in turn, the coupling of the shear to the machine compactadota to which said shear is intended; by two symmetrical knife holder (2), which are mounted in two planes different, and on which are mounted two blades (3), which They are responsible for cutting the bale of biomass (6). These blades (3) can be fixed or, as the example shows represented in interchangeable figures 3 and 4, being in this case screwed to the corresponding knife holders (2) by middle of some screws (4).

The knife holders have two support points; one of them is coincident for the two knife holders, which is fixed at all times, like the axis (5), which is also common to both. The other point of support is mobile and they go articulated hydraulic cylinders (6), which are the ones that move the knife holder to produce the bale cut (7). Cylinders They are placed on top and are attached to the chassis.

When the cylinders (6) are closed, the blades (3) separate and allow the passage of the bale (7), while when the cylinders (6) open, the blades (3) they close, producing the bale cut (7).

The shear also incorporates a funnel (8) located at the entrance of it and attached to the structure (1), funnel whose function is to center and facilitate the entry of the bale into the shear.

Detailed description of another preferred embodiment

Scissor cutting shears with double shaft fixed object of the present preferred embodiment has, likewise that in the previous preferred embodiment, a structure or chassis which absorbs the cutting forces and allows, in turn, the coupling to the compactadota machine, to which it is intended. It also consists of two non-symmetrical knife holders (2), which are mounted on the same plane and on them are installed paths blades (3) responsible for cutting the bale of biomass Said blades (3) can be fixed or, as shown by the example shown in figure 5, interchangeable, being in this case screwed to the corresponding knife holder (2) by means of screws (4).

The knife holders have two support points; the lower ones are fixed to the chassis and are not coincident for two knife holders, but they are next to each other, at same as the fixed rotation axes (5) of each knife holder, which neither are common to both, so there are two fixed axes (5) parallel to each other.

This results in torsions in the axes are smaller and, therefore, than the risk of breakage of any of them is also minor. The other point of support is mobile and the hydraulic cylinders (6) are articulated, which are those that move to the knife holder to produce the bale cut (7). The cylinders (6) are placed on the top and are subject to the chassis. When said cylinders are closed, the blades (3) separate and allow the passage of the bale (7), while when the cylinders (6) open, the blades (3) are close producing the bale cut (7) to length desired.

The shear can incorporate, as in the previous preferred embodiment, a funnel to facilitate entry and the one centered on it from the bale to be cut.

It is not considered necessary to extend this description so that any subject matter expert is able to understand the full scope of the invention to which it refers, so how many technical effects and new benefits can be derived Of the same.

The terms in which the This technical report, consisting of its description, its claims and their drawings must always be taken in their broader and less limiting sense that is compatible with the essentiality of the invention claimed therein for the purpose of Obtain adequate registration protection.
