Description

[Detailed description of the invention] The present invention relates to a crusher for wood chips.

Grinding of wood chips and bark (pulverized products) is one of the recent uses of resources, and can be used as a heat source or as a moisture source of poultry excrement.
The range of uses and amounts of firewood, compost gland material, etc. are increasing, and the demand for them is rapidly increasing. However, conventional crushers cannot crush easily crushed materials such as It was possible to crush products with low moisture content and high fiber quality, but those with high moisture content or very strong fibers, such as the bark of cedar, elm, lauan, or North Pacific wood, were able to be crushed. Strong and long wood bark with dense and fibrous texture, or 60% water content.
(WB) When trying to crush wood bark that is too bright, conventional crushers that use screens to adjust the particle size often get clogged with the screen, making it impossible to crush the bark. Grinding work was carried out by frequently stopping the continuous rotation to remove clogging of the screen, or by removing the screen. Therefore, it was not possible to grind wood chips and bark in an efficient and rational continuous manner, and the grinding products had irregular particle sizes, making it difficult to obtain good quality products.

The present invention solves the problems of conventional pulverizers, and uses a compact pulverizer that does not cause clogging, is efficient, and produces high-quality pulverized products with increased Cl content. The purpose is to provide a machine.

The details will be explained below based on the drawings of one embodiment of the present invention.

Fig. 1 is a partially cutaway perspective view of an embodiment of the non-invention crushing machine;

Figures J and 4 are perspective views of the same hammer, Figure 2 is a top view seen from arrow direction (D) in Figure 4, and Figure M6 is wood chips used as raw material for the machine of the present invention. FIG. 7 is an explanatory diagram of a crushed wood product manufactured by the machine of the present invention.

The wood chips/medium bark crusher of the present invention is generally a horizontal type (broadly referred to as a diagonal horizontal type), and the temporarily crushed material is crushed by hammers (26...) as the rotor rotates. When struck in the tangential direction of the circumference, a thrust (

... is pivoted to the rotor (2) by a pin and has a straight fixed blade, and each control will be explained one by one.

(1) is a crushing device of the present invention, which receives the crushed material (b) of wood chips and bark as shown in Fig. 6 from a hopper-shaped input one stroke, and has a cylindrical crushing base installed horizontally. As the rotor, which is rotatably supported coaxially within the shaft, rotates, a plurality of hammers (2) are moved in the radial direction of the outer circumference by centrifugal force as appropriate in the axial direction. The blades protrude at intervals, and between the top surface of the hammer caI (285) and the crushing chamber (a plurality of fixed universals spaced circumferentially on the inner circumferential wall of the IG) across a gap (C). The material to be crushed (goods) is crushed and the fibers as shown in Fig. 7 are crushed through the discharge port (2).
This product produces the following pulverized chip-shaped powder (e), and is used for transporting meji, hammer... At least the front surface in the direction of one turn of the tip facing the axial direction of the rotor circle (264Jl)
is positioned facing the discharge port (2) with a forward inclination angle (θ), thereby applying a thrust (F8) to the material to be crushed (B) from the input direction to the discharge side according to the rotation of the rotor (■). This is the special feature of the company.

The crushing chamber aI has a cylindrical shape, and the mating surfaces of the upper and lower 7 lunges 4 U-, which correspond to the central horizontal plane, are divided into an upper chamber (10a) and a lower chamber (10b) into lower halves. A hopper-shaped inlet αD is provided at one end of the royal chamber (101), and an outlet @ is provided at the lower part of the lower chamber (10b) diagonally opposite to the inlet. The outlet (2) is for the material to be crushed (transfer).

Each of the disks (2) (23 Between each disk, there are eight hammers (towards) ... which are pivoted on the periphery of the disk at a pitch of 46'.As shown in Figure 4, the hammers (towards) 2) has a boss part (262) having a shaft hole (261) that can be rotated to extend the page 6, and the boss part (262) and the head part (
264), and the front surface (264a) of the head section (164) in the rotational direction and the front surface (2!681) of the stem section (268) are connected to the discharge port - It is tapered with an anterior inclination angle (θ). Therefore, the direction of this oblique angle (θ) is such that when the rotor (2) is assembled into the rotor (2), the rotor (2) rotates as shown in FIGS. 1 and 2.

As shown in Fig. 8, the centrifugal force causes the particles to expand and protrude radially to the outer circumference of the rotor, causing the objects to be crushed @'t8
While crushing, thrust (Fs) is applied toward the discharge port (2) side, and the total rotation direction (arrow view (A)
) is a consistent formula. The rear surface (264b) is also the front surface (
It has an oblique angle (θ) parallel to 264 m) and is used when the front surface is worn. While the hammer is stopped, the hammer (■) hangs downward by its own force, as shown by the dotted line in diagram m2. There are about 4 holes on the inner circumferential wall of the crushing chamber curve, excluding the input curve, the discharge port (2), and the upper and collated 7 lunges.
The fixed blades 6, which are straight with a 5' pitch, are held in the force direction and are stopped so as to form a connection (C) with the top surface (265) of the head of the hammer (2) during rotation. There are 6 and 9 layers.

The blade (to), which is close to the income port l, has a lot of wear and tear,
It is attached to a sliding blade with a holding stone that can move forward and backward in and out directions by turning the bolt. In addition, across the circumferential direction of the inner circumferential wall circle, there is a ring-shaped weir plate t131 (1
3 are fixedly attached, forming a relatively large Ichinoseki (B) with these intermediate disks (C) and (C). As mentioned above, the crusher has a structure in which it is divided into upper and lower halves and a part (101 m) of the upper kic 10a) can be opened over the entire length, so the replacement of these weir plates Q3 (13) is expensive. It is easy to carry out, and it is also possible to inspect and replace the condition of fixed-blade Klls and spades.

When the rotor ■ driven by a motor etc. rotates in the direction shown by the arrow (circumferential speed? fJ50~60./allG), the hammer (to)... breaks at one point in Figure 2. It expands radially from the state shown by the dotted line to the state shown by the dotted line and stands up radially due to the centrifugal force, and hits the material to be crushed (b) of bark among the wood chips fed from the input port uD, and heads toward the sliding blade (2) and the identification blade circle. The zero hammers that hit the stone and shear and crush it at Ichinoseki (C) stand up in a radial manner due to centrifugal force, so stones larger than Ichinoseki (C) → 14 objects are mixed in. It is also possible to prevent accidents due to foreign objects getting caught by attaching the hook in the opposite direction to the rotating direction around the circumference of the bottle.

As mentioned above, each of the hammers (2)... has an oblique angle (θ) of 1 in the forward direction (io (2644)K) of the rotation direction of the head (264), so the As shown, the force component (F
In addition to l), it also has a force component (Fs) in one direction around the rotation axis,
A thrust force is generated to the discharge port H1ll. For this reason, the object to be crushed (&4) as a whole moves in a spiral shape within the crushing chamber, making it possible to have a long transition route. Before being discharged from the discharge port 02 as a pulverized product of the size of a boy, it is blocked by a dam plate U and undergoes the crushing action of a tamper @. The degree to which this repeated crushing action is applied is determined by adjusting the gap (the thick name of the ball), which refers to denser and longer fibers compared to wood with a lot of wood, and as the proportion of bark with a high moisture content increases.

In addition to hammers with a constricted shape relative to the head (Si20), the present invention can also be applied to hammers (2) with a hollow shaft in which the fifth part (26B) of the stem is the same thickness as the head part (164). It is clear that the straight hammer (to) with no oblique angle (θ)... has a fixed blade (to)... tilted with a forward inclination angle, and the hammer (c)... . . . and the fixed blade (2). It is clear that a blade having an oblique angle (θ) (i) on both sides also falls within the scope of the present invention.

As described above, according to the pulverizer of the present invention, the objects to be pulverized (rolled) such as wood chips and bark are tilted forward at the oblique angle (θ) toward the outlet (2) side of the front surface (2641) of the rotation direction. Since the impact is crushed by a large number of hammers equipped with a
Because the M(II) is moved in a spiral shape over a long machine, the crushing/grindability ratio is high despite its compact structure, and the material to be crushed (transferred) has a high In addition to being able to select the degree of oblique angle (θ) according to It becomes possible to manufacture the product (e).
