Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a waste input device for a crusher, which allows large box-shaped items such as refrigerators and washing machines, and long items such as waste materials to be input smoothly without blocking the input port. It is related to.

Generally, the waste that is thrown into the crusher for crushing is targeted at various types of waste that differ in size and length. A large chute is installed to accommodate it.

By the way, while increasing the depth of the chute makes it easier to accept long items when they are thrown in, sumo wrestlers often close the slot for box-shaped items such as refrigerators and laundry, as shown in Figure 4. That is, when a box-shaped waste 01 is thrown into the chute 03 from the tip of the feeding conveyor O2, the waste 01 is thrown into the chute 03 which slopes forward and downward.
It falls onto the back wall 04. At this time, the waste 01 is turned forward around the collision part 05 on the rear wall 04, and as a result, the waste 01 forms a bridge in the chute 03 near the input port 06, and There is a problem that causes it to close. The present invention provides a waste shredding machine in which large box-like items such as washing machines and refrigerators, and long items such as waste materials can be smoothly introduced into the shredding machine through the chute by appropriately providing guide members in the chute. Some provide input devices.

Embodiments of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a crushing drum consisting of a vertically installed cylindrical container 2 and an inverted conical hopper 3 connected to the upper edge of the cylindrical container 2; 4 is installed vertically at the center of the drum 1. The rotary shaft 4 has a hammer group 5 attached thereto, and is driven by an electric motor 6. An input port 7 is bored on one side of the upper surface of the hopper 3,
Further, a discharge port 8 is provided at the bottom of the cylindrical container 2.

A chute 10 facing the tip of the input conveyor 9 is provided above the input port 7, and the chute 10 has a vertical front wall 11, side walls 12, 12, and a horizontal upper wall 13. It is formed of a rear wall 14 that slopes forward and downward, and the rear wall 14 is open at the top to face the tip of the input conveyor.

15, 15 are a plurality of guide members provided in the chute 10, and the upper ends of the guide members 15, 15 are connected to the upper wall 13.
It is located in the center and its lower end is located at the lower part of the front wall 11, and is attached so that the surface facing the input conveyor 9 is inclined forward and downward.

The guide members 15, 15 are constituted by elongated rods, and the rear surfaces facing the input conveyor 9 are substantially coincident with each other, and in the left and right direction, the guide members 15, 15 are narrower than the width of a refrigerator or washing machine, and wider than the width of a long object such as waste wood. They are arranged side by side with intervals.

To explain in more detail the installation state of the guide members 15, 15, when a refrigerator or the like is placed into the chute 10 from the tip of the input conveyor 9, the input conveyor 9 is installed so that the front end of the refrigerator or the like does not hit the guide members 15, 15. A large space is formed between the tip and the guide members 15, 15, and the feed conveyor 9 falls onto the inclined rear wall 14 from the tip.
The distance between the guide members 15, 15 and the rear wall 14 is narrowed so that when the refrigerator, etc. is flipped forward with this falling point as the center of the circle, the upper end of the refrigerator, etc. abuts against the guide members 15, 15 and prevents the refrigerator from flipping. are doing.

Incidentally, reference numerals 16 and 16 indicate attachment members for attaching the guide members 15 and 15 to the front wall 11.

With the above configuration, when a refrigerator, a washing machine, etc. is loaded into the chute 10 by the current input conveyor 9, the tip of the input conveyor 9 is reversed as shown in FIG. It falls onto the inclined rear wall 14.

At this time, the refrigerator, etc. tries to turn further forward around the falling point, or the upper end of the refrigerator, etc. collides with the guide members 15, 15 on the body, and there is no turning effect, and as a result, the refrigerator, etc. state of. (m) It is guided into the crushing drum 1 by sliding on the inclined rear wall 14 surface and the hopper 3 surface.

Inside the crushing drum 1, the pieces are crushed by a group of rotating hammers 5, and the crushed pieces are discharged from a discharge port 8 at the bottom.

Next, as shown in FIG. 3, a long object such as waste material is thrown into the chute 10 from the feeding conveyor 9, and the tip of the long object passes through the gap between the guide members 15 and 15 into the chute 10. It is possible to penetrate deep into the chute 10, so that the long object can freely turn over inside the chute 10.
It will be guided into the crushing drum 1 through.

Although the guide members 15, 15 are made of rod-like members, they may also be plate-like members arranged side by side with appropriate spacing between the left and right sides.

As described above, the present invention has a slope facing the tip of the input conveyor in the chute, and a plurality of guide members arranged in parallel at appropriate intervals in the left and right direction, so that large boxes such as refrigerators, washing machines, etc. Long objects such as solid objects and waste materials can be smoothly guided into the crushing drum through the chute, thereby allowing efficient crushing work.
