Description

Cutting shear with sliding.

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

Background of the invention

Biomass packaging is used to reduce 80% of forest waste produced after logging forests, such as small logs, branches, bushes and crusts that fall into the biomass category. With the collection of this waste is achieved a double benefit: on the one hand the energy production and, on the other, the reduction of the risks of forest fire declaration.

The devices for cutting bales of biomass are usually located in the final part of the balers

There are currently various types of devices destined to the cut of biomass, but, in general, they present a gouge cutting chain based mechanism. These are gadgets are inefficient and durable, since the wear of the chains causes its breakage with relative frequency.

The present invention of a cutting shear with sliding, applicable to a compaction device or biomass packaging, presents different advantages with respect to Existing devices: produces a cleaner cut of the bale; it requires less maintenance, and is more robust, which allows to reduce breakdowns, with the consequent reduction of costs and productivity increase.

Therefore, the shear with sliding of the invention supposes a new more advantageous alternative with compared to those offered by cutting devices so far existing for the cutting of biomass bales.

Description of the invention

The present invention relates to a shear Sliding cutter applicable to a compaction machine or biomass packing.

The corresponding device is constituted essentially by a structure or chassis, one or several knife holder, one or more blades, one or more double cranks and one or several hydraulic cylinders.

The chassis is the structure that supports the shear in question and which, in turn, allows the coupling of said cutting device to a compacting or packing apparatus of biomass To him are articulated the knife holders and the hydraulic cylinders.

The blades, mounted on the knife holder, can be fixed or interchangeable, in which case they will be atomillable to the knife holders.

Each knife holder is attached to a cylinder hydraulic through a double rod that is responsible for receive the linear movement of the hydraulic cylinder and transmit it to the corresponding knife holder, getting it to perform a circular movement that allows to open and close the blade when The cylinders change position. So that the crank can transmit this movement, it is necessary that at the junction of the connecting rod with the cylinder has some rolling pins.

Each knife holder has, therefore, two points of support, one of which is fixed to the chassis, while the other moves, coinciding with one of the support points of the cranks double. The cranks also have two points of support; one of they are the one already indicated, coinciding with the mobile support point of the  knife holder, and the other is at the junction point of said connecting rod with the hydraulic cylinder.

The hydraulic cylinders, responsible for knife holder movement, perform the necessary force to that the cut occurs. The cylinders are placed horizontally at the bottom and / or top and are articulated to the chassis, of so that the efforts are absorbed by it.

Thus, as described, it can be summarized that the cutting mechanism of the present invention functions from the following way: the hydraulic cylinder moves linearly and transmits the movement to the cranks, which, in turn, transmit it to the knife holder, thus producing the cutting movement of the knife.

The shear with sliding, object of The invention presents as innovation the transmission of movement between the hydraulic cylinder and the knife holder a through a double rod. In addition to the cut is produced by middle of the shears placed coplanarly in order to cover all the periphery of the biomass bale.

Detailed description of a preferred embodiment

To help you better understand everything described previously, an embodiment is described below preferred of the invention, which corresponds to a cutting shear with sliding comprising the parts and elements that are indicate and describe in detail the act followed.

It consists essentially of a structure or chassis (1), which absorbs cutting forces and allows, in turn, the coupling of the shear to the machine compactor to which it is intended; by four knife holders (2), in those that are mounted the blades (3); by four cylinders hydraulic (4), by four double connecting rods (5) connected to the cylinders using articulation bolts (6) and a support ring an "optional" feed funnel, which allows the fastening the funnel to the shear chassis (7). The four of them Knife holders are symmetrical, and are mounted two at a time, as It is indicated in Figure 3, producing each pair of blades a cut. The cuts are produced coplanarly, being necessary for the total cutting of the bale (8) the cutting of both pairs of blades (3).

The knife holders (2) have two points of support, one of them is fixed to the chassis (1) and is different in each one of them. The other is mobile and the cranks are articulated doubles (5), which transmit the movement of the cylinders hydraulic (4) to the knife holder (2), getting these make a circular movement that allows to open and close the blades (3). When the cylinders are closed, the blades they separate and allow the bale to pass (8). Subsequently the cylinders are opened by sectioning the bale to the desired length. The cylinders are placed horizontally on top and bottom of the device and are articulated to the chassis, which is the mechanical element that absorbs stress.

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.
