Problems to be solved by the compact tractor attachments
The present compact tractor attachments can use not only so-called new wood, but also recycled wood as a semi-finished material, the assembly volume is considerably smaller than the traditional direct PTO wood chipper, and thus it costs less investment costs, additionally , it's an object to supply a way and apparatus which will be used flexibly and is essentially suitable for manufacturing an OSB chip.
Means for Solving the Problems
This traced back to the essential features, but changed the boundary conditions from the bottom up. This relates especially to the choice of the size of the semi-finished material. Such a semi-finished material is taken into account to be bar-shaped because the dimensions in one spread is larger than the dimensions within the spread perpendicular to the spread.
With the tactic consistent with the compact tractor attachments also because the device like this method, now a considerably different semi-finished material, i.e. not only new wood of superior material but also new wood of less good material, wood with knots, And branches and recycled wood are often used. Here, samples of the recycled wood include packaging wood that's generated enormously.
As described above, the tactic and apparatus of this compact tractor attachments can basically produce expensive OSB chips, but also can produce lower quality wood chips at an equivalent time. If different categories of wood chips are produced, they will be classified through subsequent classification steps.
DETAILED DESCRIPTION OF THE COMPACT TRACTOR ATTACHMENTS for Branson Tractors, Kioti Tractor, and so on.
Hereinafter, embodiments of this compact tractor attachments are going to be described intimately with regard to the drawings.
As are often seen from FIGS. 1 and 2, the pto wood chipper includes a rotor 1 driven by a shaft 2. The rotor 1 has an annular portion (crown portion) composed of a plurality of blades 3 parallel to the axial direction. Similarly, a cutter basket having a plurality of cutters 4 provided in parallel within the axial direction surrounds the rotor 1. The rotor 1 and therefore the cutter basket are further arranged during a casing 5 and are surrounded together by this casing. The casing 5 is given a supply port 6 for a bit of wood to be supplied and a discharge port for a finished wood chip.
FIG. 2 shows the rod-shaped semi-finished material 20 in two places. within the present specification, the semi-finished material may be a cubic block unless otherwise specified. However, rather than the block, this semi-finished material may produce other shapes, for instance it's going to have an irregular outer surface. what's important is just that the semi-finished material 20 is more or less rod-shaped, i.e. having a predetermined longitudinal length, during a plane extending perpendicular to the longitudinal direction. it's only longer than the lateral length.
The semi-finished material 20 is fed into the shaft-like supply port 6 (see arrow). Then, this semi-finished material 20 reaches the inner chamber surrounded by the rotor 1. At this point, the semi-finished material 20 is laid down naturally or by an appropriate orientation device, in order that the semi-finished material extends generally along the longitudinal axis of the rotor head 2, and as a result it's more or less parallel to the cutter 4. The semi-finished material is considerably larger, especially especially length, compared to a bit of wood that has been poured into conventional cutter-ring type pto wood chippers.
FIG. 3 shows the cutter assembly during a cross section perpendicular to the axis. This cutter assembly may be a component of the cutter ring of the apparatus .
Each cutter assembly is assembled as follows: the holding block 10 holds the cutting cutter 11. The cutting cutter is fixed to the holding block 10 by a clamp plate 12 and screws 13.
Each holding block 10 features a wear surface 10.1. Critically important is that the wear and tear surface 10.1 facing towards the device axis is substantially flat and thus not concentric as within the prior art.
In this case, the wear and tear surface 10.1 is made from a wear plate 10.2. This wear plate is fixed on the remaining holding block 10 on its own surface. the wear and tear surface 10.1 could also be formed from a wear layer . This wear layer is preferably formed by coating of the wear and tear layer by surfacing welding or spray coating and subsequent surface treatment.
In the embodiment consistent with FIG. 3, a stock cutter 14 is provided. This stock cutter is fixed to the holding block 10 on the side opposite to the cutting cutter 11, and functions along side the cutting cutter of the adjacent cutter assembly. In contrast to the present , the embodiment of FIG. 4 is configured such no stock cutter is provided.
