Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a kitchen waste processing machine that crushes kitchen waste generated during cooking, etc., and separates and removes moisture from the kitchen waste, while at the same time reducing its volume.

[Conventional technology]

Usually, most of the kitchen waste generated during cooking in the kitchen contains a large amount of water and is easily spoiled in a short period of time, and when accumulated, it is heavy and difficult to handle.

For this reason, it is common practice to drain the water from kitchen waste using a colander or a net before disposing of it, but this only allows the water adhering to the surface of the kitchen waste to be separated by natural flow; It is not possible to remove the moisture trapped between kitchen waste. In addition, it takes a considerable amount of time to thoroughly drain the water, which is not only inefficient, but also unsanitary, with cockroaches and flies getting stuck in the kitchen waste while draining the water.

[Problem that the invention seeks to solve]

This invention was made as a result of intensive research in view of the current situation, and it is possible to squeeze and separate water from kitchen waste containing a large amount of water, and reduce its weight and volume.
The purpose of the present invention is to provide a kitchen waste processing machine that can effectively process kitchen waste.

[Means for solving problems]

The kitchen waste processing machine according to the present invention is provided with a hopper for inputting kitchen waste, faces a lower end outlet of the hopper, supports a pair of crushing rollers for crushing the kitchen waste, at least one of which is movable toward and away from the other; A kitchen waste processing machine is provided with a pressurized pusher and a pusher that can freely move forward and backward to feed the kitchen waste toward the rotating crushing surfaces of the two crushing rollers, and the kitchen waste thrown into a hopper is A pusher that slides back and forth at the lower end of the waste feeds it toward the crushing surfaces of both crushing rollers, and by crushing it with both crushing rollers, it reliably removes even the moisture contained in the kitchen waste and makes the kitchen waste smaller and more compact. This prevents kitchen waste from rotting and maintains a clean condition, while also making it easier to handle when transporting food waste.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the kitchen waste processing machine of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the kitchen waste processing machine of the present invention has a hopper 1

A shaped spring 20 is interposed to constantly press and bias the upper crushing roller 3 so that it can move toward and away from the upper crushing roller 3 in the vertical direction. As a result, the lower crushing roller 4 is rotated by the upper crushing roller 3 due to the pressure contact between both rollers 3.4, and when the food waste is sent by the pusher 5 to the crushing surface C of both rollers 3, 4, both It is crushed between crushing rollers 3 and 4, and water is squeezed out. Here, both the crushing rollers 3 and 4 are vertically arranged, and the lower crushing roller 4 is in pressure contact with the upper crushing roller 3 at the highest position on the circumferential surface of the lower crushing roller 4, so that the squeezed water is removed. The water flows well along the right half of the circumferential surface of the lower crushing roller 4, and the lower water receiver falls into the dish 7. 21
and 22 are crushing surfaces C of both crushing rollers 3 and 4, respectively.
This is a scraping tool placed on the lower side of rotation.

The pusher 5 is disposed directly below the outlet 2 of the hopper 1, facing the crushing surfaces C of the crushing rollers 3 and 4. This pusher 5 is formed into a hollow box shape surrounded by a stainless steel plate, and its width is made almost the same as that of the crushing rollers 3 and 4, and the pushing end surface 5a facing the crushing surface C is a boat-shaped downward slope. The kitchen waste is prevented from escaping above the omper 1 during feeding, and the large kitchen waste is preliminarily pulverized into small pieces by the sharp upper tip of the pushing end surface 5a.

This pusher 5 is supported so as to be able to slide forward and backward on a sliding guide plate 23 connected to the machine frame 6. The sliding guide plate 23 is located slightly below the crushing surface C, and its side end is connected to the drainage gap 23. It is provided so as to face the circumferential surface of the lower crushing roller 4 across from it. The pusher 5, which is thus supported on the sliding guide plate 23 so as to be able to move forward and backward, has a motor 12 disposed at the lower end of the machine frame 6, a belt 13, a reducer 14, an intermediate shaft 16,
A connection provided at the tip of the swinging arm 28 that rotates the eccentric cam 27 via the pusher belt transmission mechanism 25 and the camshaft 26 and swings in contact with the eccentric cam 27! 29 is engaged with the passive pin 30 protruding from the side surface of the pusher 5, and the swinging arm 28
is driven forward and backward toward the crushing surface C, and the fourth

A passive pin 30 is slidably supported in a left-right relief groove 33 formed on the side wall of the
The pusher 5 is urged in the backward direction through the. Furthermore, when the feeding pressure of the pusher 5 exceeds a certain level, the buffer spring 32 shrinks and deforms to absorb the movement of the swing arm 28 and prevent the pusher 5 from being forced to feed.

The advancing and retreating cycles of the pusher 5, which is slid back and forth in this manner, are set so that the amount of kitchen waste taken in by the crushing rollers 3 and 4 is slightly larger than that of the kitchen waste. When feeding, preliminary dehydration is performed.

The water tray 7 is disposed extending from below the lower crushing roller 4 to below the sliding guide plate 23 to catch the water squeezed between the crushing rollers 3 and 4 by the sliding of the pusher 5. The water collected in the tray 7 is led out of the machine frame 6 through a drain pipe 34, and is discharged, for example, to a sewer pipe in the kitchen.

In addition, the kitchen waste from which water has been removed by the crushing rollers 3 and 4, that is, the processed kitchen waste d, is stored in a collection located below the rotational center of the lower crushing roller 4 on the lower side of the rotation of the crushing rollers 3 and 4. It is housed in box 8. This accumulation box 8 is opened and closed by opening and closing the lid 36 from the loading/unloading port 35 opened in the side wall of the machine frame 6.
A bottom plate 37 is supported in the inner court of the collection box 8 so as to be able to swing up and down. A switch 38 is provided, and a balance spring 39 is provided to determine the weight of garbage at which the switch 38 is activated. When the accumulated amount of processed kitchen waste d approaches the limit amount, the switch 38 is activated, and notification devices such as a buzzer and an indicator lamp attached to the machine frame 6 are activated, and the processed kitchen waste in the collection box 8 is activated. Encourage the disposal of d. Note that 40 is a waste bag set in the collection box 8.

[Effect]

In the kitchen waste processing machine of the present invention configured in this manner, when the start switch (not shown) is turned on after putting kitchen waste into the flopper 1, the motor 12 is driven, the belt 13, the speed reducer 14, and the belt transmission mechanism are turned on. 15, the crushing roller 3 is rotationally driven in the clockwise direction and the crushing roller 4 is rotationally driven in the counterclockwise direction via the intermediate shaft 16 and the belt transmission mechanism 17. The pusher 5 is driven forward and backward via a belt transmission mechanism 25, a camshaft 26, an eccentric cam 27, and a swing arm 28. At the same time, valve 1
1 is opened, water is sprinkled into the hopper 1 from the water sprinkling pipe 10, and the food waste in the hopper 1 is weighted by this water spraying and is surely dropped to the outlet 2 side. Then, it is pushed by the pushing end surface 5a of the pusher 5 and sent to the crushing surfaces C of both the crushing rollers 3 and 4, and is crushed between the two crushing rollers 3.4 to squeeze out the moisture and compress it. Volume becomes smaller. At this time, crushing is performed without changing the distance between the crushing roller 4 and the upper crushing roller 3 by the action of the spring 20 depending on the hardness or softness of the food waste or the size thereof. The water separated from the kitchen waste is collected in a water tray 7 and drained out of the machine via a drain pipe 34. In addition, the processed kitchen waste d is dropped into the disposal bag 40 of the collection box 8,
When the accumulated amount exceeds a certain amount, the switch 3B is activated to notify that the waste bag 40 needs to be replaced. After the treatment work is completed, the motor 12 is stopped by turning off the starting switch, and at the same time, the valve 11 is also closed and the water supply to the water sprinkling pipe 10 is also stopped.
