Description

[Technical Field]

[0001] The present invention relates to a method for reducing the volume of trash in a trash container by elevating a drive unit itself when compressing and reducing the volume of trash in the container. [Background technology]

[0002] Conventionally, various types of garbage volume reduction means have been used, a typical example of which is a means for compressing and reducing the volume of garbage by lowering a compression plate into a garbage container. Hydraulic cylinders are often used as the driving source, and pantograph systems are also used, but there are no examples of the drive unit lifting system shown in the present invention. Summary of the Invention [Problem to be solved by the invention]

[0003] It is desirable for a garbage volume reduction device to be able to be used in a small space, but the hydraulic cylinder method mentioned above has the problem that the hydraulic cylinder is positioned vertically above the garbage container, making the overall height of the device large. Also, the pantograph method uses an X-shaped telescopic link mechanism, which makes it possible to make the compression mechanism compact, but there is a risk that garbage will get into the gap between the garbage compression device and the driving member such as the feed screw when the garbage compression device descends, causing a malfunction. In view of the above, the present invention was invented with the aim of providing a new and useful means for achieving sufficient compression and volume reduction of garbage in a small space by raising and lowering the drive unit itself using a roller chain and sprockets, rather than a hydraulic cylinder or pantograph system. [Means for solving the problem]

[0004] As a means for solving the problems, the present invention has the following configuration. In other words, a housing capable of accommodating a garbage container has a drive unit that can be raised and lowered relative to the housing, a lift plate that can be raised and lowered relative to the drive unit, and the lower end of the lift plate has a pressing part for compressing the garbage, and the garbage is compressed using the lifting method of the drive unit.The present invention is a garbage compression volume reduction method using the drive unit lifting method configured as described above. [Effects of the Invention]

[0005] According to the present invention, the garbage volume in the garbage container can be compressed and reduced by a dual lifting system, which involves lifting the drive unit and the lifting plate, resulting in a garbage volume reduction method and device that is more compact than conventional systems.In addition, by using a rearward diagonal positioning system for the drive unit, as described below, the movable range of the garbage input door can be increased. [Brief explanation of the drawings]

[0006] [Figure 1] Illustrative diagram of the structure and function of the present invention [Figure 2] Explains the structure and function of another embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0007] Hereinafter, an embodiment of the present invention will be described. In the figure, reference numeral 1 denotes the housing, which is a hollow metal box body, with an opening and closing door (not shown) on the front for inserting and removing the garbage container, and above this opening and closing door there is a garbage inlet with a push-open type garbage inlet door 2. A top-open garbage container 3 made of synthetic resin or the like is placed on the bottom of the housing. Reference numeral 4 denotes a fixed plate, the upper part of which is bent at a right angle and screwed to the upper part of the housing so as to hang down, and a chain connector 5 is provided on the lower end side of this fixed plate to connect and fix the roller chain described below to the fixed plate.

[0008] Reference numeral 6 denotes an upper sprocket and 7 a lower sprocket, and a roller chain 8 is positioned between these sprockets. Reference numeral 9 denotes a lifting plate, the lower part of which is bent at a right angle to form a pressing part 10, and a chain connector 11 similar to the chain connector described above is provided above the lifting plate, connecting and fixing the roller chain to the lifting plate. A drive shaft 12 is fixed to the upper sprocket 6, and a driven shaft 13 is fixed to the lower sprocket 7. These shafts are rotatably held by an appropriately shaped shaft holder (not shown), thereby maintaining the relative positions of the shafts.

[0009] A geared (reduction) motor (not shown) is provided to drive the drive shaft, and this motor is fixed in an appropriate position to the shaft holder. A pair of upper and lower sprockets are provided (the one shown in the figure is the front side), and the shaft holder is raised and lowered by a guide mechanism (not shown) provided along the top and bottom of the inner surface of the housing. The upper sprocket, drive shaft, lower sprocket, driven shaft, chain connector 11, roller chain, shaft holder, and motor constitute the drive unit 20.

[0010] The function and use of the present invention will now be described. To use the present invention, first open the door on the front of the housing, place the garbage container inside the housing, close the door, and then insert garbage into the garbage inlet. Once a certain amount of garbage has accumulated inside the container, turn on the motor switch and the drive unit will begin operating. As the motor rotates, the drive shaft starts to rotate clockwise, which causes the sprocket to start rotating and the roller chain to start moving.

[0011] This roller chain is fixed to the fixed plate via chain connector 5, and the upper part of the fixed plate is fixed to the upper surface inside the housing, so the upper sprocket starts to descend, and at the same time the lower sprocket and motor begin to descend. The lifting plate is connected and fixed to the roller chain via chain connector 11, so the lifting plate also descends relative to the lower sprocket. The lower end of the lifting plate is bent to form a pressing portion, and when this pressing portion descends, the trash inside the trash container is compressed and reduced in volume.

[0012] In other words, the drive unit descends relative to the fixed plate, and the lifting plate also descends relative to the lower sprocket located below the drive body, providing a double descending element, allowing the vertical dimensions of the housing to be compact. After compression, the motor rotates in the reverse direction, returning the drive unit to its initial position. When a certain amount of compressed garbage has been collected, the garbage container is removed from the housing and disposed of.

[0013] Figure 2 shows another example of the present invention. While the previous example has a fixed plate hanging down from the center of the top surface of the housing, this example has a fixed plate positioned diagonally at the rear inside the housing, and as shown in the figure, it is characterized by the fact that the opening and closing angle of the garbage disposal door can be made large. For this reason, the upper bending angle of the fixing plate is made slightly acute, and the pressing portion is also made slightly acute. Furthermore, by arranging the pressing portion obliquely as described above, the position of the pressing portion when lowered can be brought closer to the center of the waste container.

[0014] The present invention has been described above. The present invention is characterized by a double lifting system in which both the drive unit and the lifting plate are lifted, and can provide a space-saving housing not available in the past. The illustrated embodiment is merely an example, and the shapes of the fixed plate, lifting plate, etc. can be modified as needed. The shape and configuration of the shaft holder can also be freely chosen as long as it is suited to the purpose. As described above, the present invention provides a space-saving and efficient garbage compression and volume reduction device. [Explanation of symbols]
