Description

  The present invention relates to a so-called volume reduction device that reduces the volume of dust in a dust box.

  Conventionally, there is a device for reducing the volume of dust in the dust box (trash box), but the plate body is moved up and down by hydraulic pressure and the dust is compressed by this plate body. As shown in the present invention, the crank There is no garbage volume reduction device using the mechanism.

As described above, since the conventional dust volume reducing device is a method of moving the plate up and down with hydraulic pressure, a hydraulic device for sending oil to an actuator such as a cylinder is required, which makes the entire device large. It was expensive and its operability was not sufficient.
The present invention was invented in order to solve the problems associated with the conventional dust volume reducing device as described above, and an object thereof is to provide a simple dust volume reducing device using a motor and a crank mechanism. Is.

As means for solving the problems, the present invention comprises the main part of an outer frame, a pressing plate provided in the outer frame, and a pressing plate driving mechanism.
That is, an outer frame having an appropriate shape is formed, and a pressing plate is provided at an appropriate position in the outer frame so as to be rotatable about one end thereof, and a pressing plate driving mechanism for rotating the pressing plate is provided in the outer frame. Provided.
The present invention is a dust box volume reducing device having the above-described configuration.

  According to the present invention, a pressing plate driving mechanism using a pressing plate and a motor is provided in the outer frame, and the mechanism has the pressing plate that rotates around one end of the pressing plate. Therefore, the apparatus can compress and reduce the volume efficiently because it is a device that compresses dust by turning rather than simply moving the plate up and down. In addition, since the apparatus is simple, a new and useful apparatus that can be installed at low cost can be provided.

Hereinafter, embodiments of the present invention will be described.
In the figure, reference numeral 1 denotes an outer frame, which is formed by joining a metal rectangular plate body into a square frame shape, a trapezoidal accessory plate 2 at the front of the lower end, and an L-shaped cross section at the rear. The contact plates 3 are fixed to each other.
Further, the support shaft holding plates 4 are respectively fixed to both sides of the outer frame rear middle position. This support shaft holding plate has a shape in which a small plate is fixed to an inner middle portion of an L-shaped plate.
A motor mounting plate 5 is formed by fixing a U-shaped plate for reinforcement on a flat plate, and is fixed to the lower surface of the upper part of the outer frame. Reference numeral 6 denotes a speed reducer incorporating a plurality of gears, and is screwed to the lower part of the motor mounting plate. Reference numeral 7 denotes a motor which is provided integrally with the reduction gear. The motor mounting plate is appropriately provided with a hole for projecting the motor shaft and a hole for screwing. A flat arm 8 has one end attached to the output shaft of the speed reducer, and a rod-like rod 9 is pivotally supported on the other end of the arm.
Reference numeral 10 denotes a support shaft, which is attached between the support shaft holding plates via bearings (not shown).
Reference numeral 11 denotes a pressing plate. The pressing plate is formed into a substantially triangular shape in a side view and a quadrangular shape in a plan view by fixing a plurality of flat plates. As shown in FIG. 2, both sides of the pressing plate are extended and fixed to the supporting shaft through a supporting shaft. In addition, a reinforcing rib is fixed at an appropriate position inside, and a substantially U-shaped support plate 12 is fixed near the center. The lower end of the rod is pivotally supported by this support plate.
The above-mentioned motor, speed reducer, arm, and rod constitute a pressing plate drive mechanism.
Although not shown, a switch for operating the apparatus is attached at a suitable position on the outer frame, and power is distributed to the motor and the switch.

In order to use the present invention, a dust box containing dust to be reduced in volume is first pushed down the outer frame. Since the accessory plate 2 is fixed to the outer frame, the dust box enters the outer frame along the accessory plate, but the lower plate 3 is located at the lower rear part of the outer frame, and the lower part of the dust box hits the outer plate. Move to position. Further, a plate body is located in the middle portion of the support shaft holding plate, and as shown in FIG. 2, the upper end of the dust box is located close to the plate body, and the upward movement of the dust box is restricted. The pressing plate is moved upward so as not to hinder the insertion of the dust box.
Next, when the motor starts rotating by the switch operation, the reduction gear configured integrally with the motor also starts to operate. An arm is attached to the output shaft of the speed reducer, and a rod is rotatably supported on the rod end and a pressing plate is rotatably supported on the rod end, so that the arm moves circularly but the rod moves close to reciprocating motion. One end of the pressing plate is attached to a pivotable support shaft, and the rod end is pivotally supported via the support plate. Therefore, when the arm rotates, the pressing plate moves up and down in an arc shape within a predetermined range.
The dust in the dust box can be compressed and reduced by the vertical movement of the pressing plate.
After the volume reduction is completed, the dust box can be taken out in the reverse operation as described above, and the next volume reduction can proceed.

FIG. 6 shows another example of the present invention. In the above-mentioned example, the rod is a simple rod, but in this example, this rod is divided and a spring is interposed so that an excessive load is not applied to the movable element of the device when dust is compressed. .
A round bar-like slider 14 having a stepped portion is slidably positioned in a tubular upper rod 13 having a stepped portion and a hole in the lower portion thereof, the lower portion of the slider is fixed to the lower rod 16, and a compression coil is provided in the middle portion of the slider. In the structure with the spring 15 interposed, if excessive force is applied to the lower rod during dust compression, the slider can move upward while sliding in the upper rod against the force of the spring, and the motor is overloaded It is possible to prevent the operation parts from being damaged. Other configurations are the same as in the above-described example.
As described above, the present invention uses a motor and compresses and reduces the volume of dust by continuous up and down movement of the pressing plate, so that the configuration thereof compared to a conventional volume reducing device using hydraulic pressure. Therefore, it is possible to obtain a dust volume reducing device having various advantages such as being simple and capable of being manufactured at low cost and being easy to operate.
Note that the above-described example is an embodiment of the present invention, and other approximate shapes may be used.
Usually, the outer frame is used by being fixedly installed on the floor surface.
