Description

[Detailed Description of the Invention] This invention relates to a pretreatment device for a drum barker, and more specifically, to an improvement of a drum barker equipped with a pretreatment device.

In conventional general drum barkers, a large number of protruding blades are attached to the inner surface of the can body, and when the log placed in the can body changes its position as the can body rotates, it touches the protruding blades and breaks the bark. It is configured to be peeled off.

Therefore, is it structurally placed inside the can? The bark is peeled off only by the frictional effect of the contact between the raw wood and the protruding blade, and when stripping hard trees such as small-diameter trees, frozen trees, walnuts, and oaks, the protruding blade often breaks and the peeling efficiency is poor. There was a drawback.

In order to eliminate these drawbacks, a system has been put into practical use in which a gap is formed between two rotating can bodies and a rotary ivy is inserted between the two to forcibly peel off the bark. In this case, although a considerable effect can be expected, the peeling efficiency is still low in the case of hard trees such as frozen books, walnuts, and oaks as mentioned above.

The purpose of this invention is to eliminate these drawbacks, and the purpose of this invention is to provide an inclined fixed can body between the rotary can body constituting the drum cover and the raw wood input section, and a plurality of holes in the bottom of the can body. A part of the rotary force vines having a plurality of notches formed around the periphery is inserted into the fixed case through these holes, and a plurality of rotary force vines are pivotally supported on the mounting base. One end of this mounting base is pivotally supported on a fixed platen base, the other end of the mounting base is supported by the fixed platen board via an elastic member, and the prime mover for rotating the rotary force is supported on the fixed platen base. The front of the drum coverr, which is installed on a board stand, and is configured such that a part of the log plowing member is inserted into the fixed case through a hole formed near a cutter entry hole of the fixed case. A processing device is provided.

An embodiment of this invention shown in the drawings will be described in detail below.

Figure 1 is a side view of the drum coverr with a pretreatment device of this invention. In the figure, 1 is a fixed base plate formed of concrete, and on this fixed base plate 1 are a wood removal section 2, a drum coverr 3 , a pre-processing device 4, and an input section 5 are arranged in series.

The wood removal section 2 and the drum coverr 3 are of a well-known construction.
In the figure, 31 is a rotating can body, 32a and 32b are rails attached to the outer periphery of the can body, 33 is a pulley (not shown) to which a belt is connected to the can rotation power source, and 34a and 34b are each a pair of cans. This is a body support roller set.

An inclined can body 41 having a diameter slightly smaller than the diameter of the rotary can body 31 that holds the pretreatment device 4 is fixed on the fixed base plate 1 with support members 42a and 42b, as shown in FIG.
At the bottom of the can body 41, as will be described later, there are a cutter insertion hole 42 through which a pair of rotary force vines 43a and 43b are inserted into the can body, and an insertion hole 61 through which a log plying member 60 is inserted into the can body. Multiple holes are opened regularly in the lengthwise direction of the can.

As shown in FIGS. 2, 3, and 4, the rotary force vine unit 49 is equipped with two rotary force vines 43a and 43b each having teeth (notches) 431 on the periphery. The shafts 432a and 432b are supported by a pair of bearing members 45a and 45b, two of which are mounted on the inclined surface 441, and gears 46a and 46b are mounted to the shafts 432a and 432b, respectively, and a chain is inserted between them. 461 is hung, and the gear 46C is attached to the above-mentioned shaft 432a, and the shaft 442 is pivoted to the bearing 11 on the fixed base plate 1 at one end of the lower part of the mounting base 44, and the axis of the above-mentioned shaft 442 is The gear 4 attached to the output shaft of the prime mover 47 whose axis center is at the same level as the output shaft 471
72, and a spring 48 is attached to the other end of the mounting base 44 and the fixed base plate 1 either directly or via the base 12.

As shown in FIG. 5, the input section 5 has a substantially U-shaped hopper 51.
A time support plate 53 supported by a shock absorbing spring 52 is disposed at the bottom of the support plate, a plurality of live rollers 54 are attached to the upper surface of the support plate, and a prime mover 55 for driving the live rollers is attached to the lower surface of the support plate. A chain 56 between the main motor and the motor for transmitting the rotational force of the motor to each live roller.
a, 56b are attached.

The rotary power vine unit 49, which consists of two rotary power vines 43a and 43b, a mounting base, a prime mover 47, etc., which control a part of the pre-processing device 4 described above, is as shown in FIGS. 2 and 3. The rotary force vines 43a and 43b of each unit are arranged so as to overlap each other, and together with the rotary force vines 43a and 43b, as shown in FIG. The chamfering is made so that even if the log a fed in the direction of the arrow collides with the rotary force vines 43a and 43b, it can easily overcome them.

Further, the rotary power ivy 43a, 43b have different shapes and numbers of teeth (notches) protruding from their outer peripheries, so as to give an irregular blow to the log a and improve the debarking effect.

Further, the aforementioned log plying member 60 is inserted into the can body through an insertion hole 61 provided on the lower surface of the can body 41, as shown in FIG. The end is pivotally connected to the support column 64 through the pivot shaft 65.
It consists of a structure in which it is pivotally connected to a hydraulic or air cylinder or an electric drive device 66 via.

The drum barker of this invention is constructed as described above, and the operation for peeling the logs will be explained below.

First, although not shown, the rotary drum cover 3, rotary cutters 43a, 43b, and live roller 54 are rotated as indicated by the arrows using an operation panel.

Next, the logs a are loaded into the hopper 51 of the input section 5 using a transportation means such as a hawk lift, and the logs a are sequentially fed into the pretreatment device 4 by live rollers 54.

In the pre-treatment device 4, depending on the type and condition of the log to be debarked,
The two rotary force vines 43a and 43b of each rotary force vine unit 49 in the series are made to have different rotational directions from the rotary force vines of other rotary force vine units, or the rotational speed of the rotary force vines is made different for each unit. While the log a is stirred in the fixed can body 41 and transferred using the tilt of the can body toward the rotary drum barker 3, the teeth (notches) of the rotary power ivy 43a and 43b are used to sufficiently coat the bark. At the same time, the skin of the tree and the bark are separated by a sufficient blow, and the log plying member 60 is moved up and down to surely send the log into the next rotary drum barker 3.

As is well known, in the drum barker 3, which has countless notches in the rotary can body 31, the log a is stirred inside the can body, and the notches act to scrape the bark, so that the bark is almost completely molted, and the bark is removed from the drainage part 2. Dispose of stripped logs and bark.

In the pretreatment device 4 described above, one end of the mounting base plate 1 is connected to the fixed base plate 1.
Since the other end is supported by a spring 48, shock can be absorbed and the teeth of the rotary force vine are less likely to break.

As described above, according to this invention, an inclined fixed can body is provided between the rotary can body that forms the drum bar force and the raw wood input section, and a plurality of holes are formed in the bottom of the can body, and these holes are A part of the rotary force vines having a plurality of notches formed around the periphery is inserted into the fixed case, and a plurality of rotary force vines are pivotally supported on a mounting base, and one end of the mount is inserted. The rotary forceps are pivotably supported on a fixed platen, and the other end of the mounting plate is supported by the fixed platen via an elastic member, and a motor for rotating the rotary force is installed on the fixed platen, and the A part of the log lifting member is inserted through a shaped hole near the cutter insertion hole in the fixed can body, so that the logs transferred from the log input section enter the inclined fixed can body from the bottom. Pre-processing for stripping is performed using multiple rotary power vines, but the mounting base of the rotary power vines is elastically supported by the fixed platen, so there is no breakage of the notch blades, and the slope of the fixed can prevents the logs from peeling. However, in the present invention, a log lifting member is inserted from the bottom of the fixed can body to push up the pretreated logs, which has the effect of ensuring that the logs are transferred to the drum barker reliably. be.
