Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pulverizer for pulverizing relatively soft materials such as lock fibers or heat insulating materials.

By loosening the lock fiber, which is made by compressing and compacting inorganic fibers whose main ingredients are silicic acid and lime,
It is recommended to apply it to fields as Keical fertilizer or to use it as a bed soil for growing seedlings for rice transplanters, but since this rock fiber is light and flexible, it will be difficult to crush it with a rotating crushing blade. It becomes difficult to crush finely as it floats up from the crushing blade, and moreover, when crushed, it loosens into light fibers that become entangled with the crushing blade and cause clogging. There are obstacles that prevent the lock fiber from being pulverized, and it is desired that a pulverizer suitable for efficiently pulverizing this lock fiber be developed.

The present invention was developed in response to this demand, and is capable of efficiently pulverizing materials that are relatively soft, such as lock fibers and heat insulating materials, and that tend to loosen into fibrous materials when crushed. Moreover, it is an object of the present invention to provide a new means by which the objects to be crushed can be transported at the same time.

In the present invention, as a means to achieve this objective, a rotational axis along the axial direction is provided at the axial center of a drum-shaped casing with the axial direction being the horizontal direction and an intake opening in the center of the front wall. A shaft is pivotally supported, a disc-shaped blade mount is mounted on the rotating shaft, and a propeller twisted in the retraction direction with respect to the intake is mounted at the center of the blade mount on the side facing the intake. A rotary blade shaped like a rotary blade is provided, and a number of cutting blades protruding from the blade mount toward the intake port are provided around the blade, and a plurality of grooves are provided on the outer edge of the periphery of the blade mount. A fixed blade is installed on the inside of the peripheral wall of the casing at a position corresponding to the rotation locus of the groove in the outer edge of the blade, and a fixed blade is installed on the peripheral wall of the casing. A pulverizer is proposed in which a conveying gutter is connected to the discharge port and a supply gutter is provided outside the intake port of the casing.

Next, an example of implementation will be described in detail with reference to the drawings.

The bearing holding member 20 is positioned so as to be aligned with the axis of the shaped casing 1.
The inner end projecting from the casing 1 penetrates the rear wall 14 of the casing 1 described above and projects into the casing 1.

The blade mount 3 is formed into a disk shape and also serves as a flywheel, and a boss portion 3 is provided at the axial center of the blade mount 3.
0 is mounted on the aforementioned rotating shaft 2 by fitting it into the inner end portion of the rotating shaft 2. The propeller-shaped rotary blade 4 is attached to a central portion of the blade mount 3 on the front side facing the intake port 1a. As shown in FIG. 5, this rotary blade 4 has a pair of blade parts 4 extending radially from a mounting seat 41 provided with a bolt hole 40 into which a set bolt 4a is inserted.
2 and 43 are formed in the shape of a protruding propeller, and when the rotary blade 4 is assembled with the set bolt 4a as shown in FIG. 3, it is rotated by the drive of the rotary shaft 2. In some cases, a twist is provided in a direction in which the object to be crushed that comes into contact is drawn in from the above-mentioned intake port 1a side.

Further, the cutting blade 5 provided around the propeller-shaped rotary blade 4 has a bolt hole 50 into which a set bolt 5a (Fig. 3) is inserted, as shown in FIG. 4, at both ends of the mounting seat 51. The blade portions 52 that stand up approximately vertically are formed in a U-shape as a whole, and the pair of blade portions 52 are arranged along an imaginary circle centered on the rotation axis of the blade mount 3. , as shown in FIG. 3, and is attached to the wall surface on the front side of the cutter holder 3 with a set bolt 5a as shown in FIG. 2.

The blade plate 6 is formed by continuous molding integrally with the blade mount 3 when the blade mount 3 is formed into a disc shape to form a flywheel.
On the outer edge thereof, V-shaped grooves 60 are formed in parallel, as shown in FIG.

The fixed blade 7 corresponds to the indentation groove 60 of the wing plate 6.

Further, the supply gutter 8 is connected to the intake port 1a of the casing 1.
It is formed in the shape of an oblique hopper surrounding the outside of the casing 1, and the proximal end thereof is connected to the edge of the intake port 1a of the casing 1.

In the illustrated embodiment, 21 is a transmission wheel provided at the outer end of the rotating shaft 2, and 90 is a machine frame a.
A set bolt 92 is installed in a mounting plate 91 provided in an arc shape on the outer circumferential side of the peripheral wall 11 of the casing 1 through a set hole provided in an arc shape along an imaginary circle centered on the axis of the drum-shaped casing 1. They are slidably fitted together, and by loosening the tightening of the set bolt 92, the casing 1 and the conveying gutter 13 can freely rotate around the axis, and this rotation allows the conveying gutter 13 to rotate freely. It becomes possible to change and adjust the protrusion angle.

The embodiment device constructed in this manner operates as follows.

While the transmission wheel 21 provided at the outer end of the rotating shaft 2 is driven and rotated by the output shaft of the prime mover, the material to be crushed R such as lock fibers is fed into the supply gutter 8 as shown by the chain line in FIG. When the object R enters the casing 1 through the intake port 1a of the casing 1, it is crushed by a large number of cutting blades 5 attached to the front side of the rotating plate-shaped blade holder 3. The air is then guided in a desired direction by the conveyor gutter 13 discharged from the discharge port 12 provided in the peripheral wall 11 of the casing 1 by the vanes 6 provided on the periphery of the blade mount 3 and discharged from the tip of the tube. will be done.

At this time, the material to be crushed R, which is slightly expanded and soft, is put into the supply gutter 8, flows into the casing 1 through the intake port 1a provided at the center of the front wall 10 of the casing 1, and rotates. Disc-shaped blade mount 3
