Abstract

PROBLEM TO BE SOLVED: To provide a grinder capable of maintaining the center of gravity of a rotating part during grinding and capable of reducing the vibration of the whole device. SOLUTION: A crushing blade 8 is pivotally supported in freely rotatable state with a shaft part 15 as the center at the tip of a roller chain 7 mounted to a rotary shaft 5 in a crushing chamber 4. A shaft part 15 being the rotation center of the crushing blade 8 and the center position of gravity of the crushing blade 8 are made to be coincided so that the gravity center balance of the rotary part may not collapse even if tip crushing blade 8 is rotated with a supporting point as the center during grinding. In such a way, the gravity center balance of the rotary part is maintained and the vibration of the whole device is reduced even if the crushing blade 8 is varied with own supporting point as the center during grinding.

[0008]

DETAILED DESCRIPTION OF THE INVENTION The invention according to claim 1 is provided with a pulverizing chamber for pulverizing a processed material supplied from an input port, an outlet provided at a lower portion of the pulverizing chamber, and a pulverizing chamber. A vertical rotating shaft that is driven and rotated by a motor, a bendable connecting body that is connected to the rotating shaft and rotates about the rotating shaft, and a crusher that is rotatably provided at the tip of the connecting body. The center of rotation of the crushing blade coincides with the center of gravity of the crushing blade. With this configuration, even if the crushing blade rotates around its own support point during crushing, the center of gravity of the rotating portion is formed. The balance can be maintained and the vibration of the entire apparatus can be reduced.

According to a second aspect of the present invention, in the crusher according to the first aspect, the crushing blade has a substantially circular shape and a peripheral edge thereof has a saw blade shape. It has the same effect and the crushing performance is further improved.

According to a third aspect of the present invention, there is provided the crusher according to the first aspect, wherein the crushing blade is formed by stacking a plurality of blades. And a plurality of crushing blades act as scissors to cut fibrous materials and the like.

According to a fourth aspect of the present invention, there is provided the crusher according to the third aspect, wherein the crushing blade has a polygonal shape and a corner has an edge. And the crushing performance is further improved.

(Embodiment 1) FIG. 1 is a side sectional view of a crusher according to Embodiment 1 of the present invention, and FIG. 2 is a transverse sectional view of the crusher.

In FIG. 1, 1 is a motor, 2 is a bracket, 3 is a pulverized material discharge path, and 4a is a substantially cylindrical casing forming a peripheral side wall of the crushing chamber 4. 5 is a vertical rotating shaft driven by the motor 1 to rotate, 6 is a fixed blade protruding from the peripheral wall of the crushing chamber, 7 is a roller chain as a bendable connecting body connected to the rotating shaft 5, 8 is a roller chain 7 is a crushing blade that is rotatably (rotatably) axially attached to the tip of the shaft 7 by the shaft 15. As shown in the figure, the crushing blade 8 has its center, which is the position of the center of gravity, mounted on the shaft portion 15 (FIG. 2).
See also). Reference numeral 9 denotes a bottom plate fixed to the bracket 2, 10 denotes an input port of the processed material at the upper part of the crushing chamber 4, and 11 denotes an input port 1.
0. Therefore, when the motor 1 is driven, the roller chain 7 rotates about the rotation shaft 5.

Reference numeral 12 denotes a bottom of the sink. When the upper end of the casing 4a is connected to the bottom 12 of the sink, the crusher is mounted on a sink. A discharge port 13 is attached to the lowermost portion of the pulverized material discharge path 3. 14 is a water tap. The connecting member is not limited to the roller chain 7, but may be a chain member such as a chain, a flexible member such as a wire, nylon, or a rope, or an elastic member such as rubber or a spring. If it is a crushed material, it is less likely to be locked during the initial stage of grinding or during grinding.

In FIG. 2, the crushing blade 8 has a disk shape.
Its periphery is shaped like a saw blade. The shaft 15, which is the center of rotation of the crushing blade 8, matches the center of gravity of the crushing blade 8.
Further, with the roller chain 7 extended, the distance between the tip of the crushing blade 8 and the peripheral wall of the crushing chamber is constant, and the crushing effect can be further improved.

With regard to the crusher configured as described above,
The operation will be described below. First, kitchen garbage is introduced from the inlet 10 of the crusher. Next, the motor 1 is started while the faucet 14 is opened and water is flowing, and the roller chain 7 and the crushing blade 8 are rotated. Then, the roller chain 7 and the crushing blade 8 are in a state of being opposed to the inside of the casing 4a, that is, the inner surface of the pulverizing section by centrifugal force.

The thrown garbage is rotated by the roller chain 7 and blown toward the crushing blade 8 and the fixed blade 6 by centrifugal force. Here, the kitchen waste is cut between the fixed blade 6 and the crushing blade 8 rotating at a high speed and finely crushed. At this time, since the crushing blade 8 is attached to the roller chain 7 and rotates around the shaft portion 15 each time it collides with the garbage, the rotation center of the crushing blade 8 coincides with the position of the center of gravity. Therefore, since the balance of the center of gravity of the rotating part (the rotating shaft 5, the roller chain 7, and the crushing blade 8) is rotated without breaking, the vibration of the entire apparatus is reduced.

(Embodiment 2) FIG. 3 is a perspective view showing the vicinity of a crushing blade of a crusher according to Embodiment 2 of the present invention. FIG.
, A crushing blade 8a is provided at the tip of the roller chain 7,
A plurality of upper and lower (two in this embodiment) shafts 8b are rotatable about a shaft portion 15 serving as a support point. Crushing blade 8a,
8b is a square having an edge at a corner.

As described above, since the crushing blades 8a and 8b are composed of a plurality of upper and lower crushing blades, each of the crushing blades 8a and 8b is crushed during the crushing.
As a and 8b oscillate, fibrous materials which are hard to be crushed are also sandwiched between the crushing blades 8a and 8b, and cut by the action of scissors.

Although the crusher according to the above embodiment uses kitchen waste as a processed material, the present embodiment can also be applied to a case where processed material other than kitchen waste, such as a foam tray, a plastic bottle, a magazine, or used paper, is used. In addition, the processed material such as a foam tray, a plastic bottle, a magazine, or the like is naturally dropped or moved to the crushed material discharge path 3 by a blower (not shown) or the like, and is discharged from the discharge port 13 to the outside.

[0021]

As described above, according to the present invention, even if the crushing blade fluctuates around its own support point during crushing, the balance of the center of gravity of the rotating portion can be maintained, and the vibration of the entire apparatus can be reduced.
Further, according to the third aspect of the invention, the same effect as the first aspect of the invention is obtained, and the plurality of crushing blades function as scissors, so that the fibrous material and the like can be cut more reliably. .
