Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a supply section of a storage hopper for various kinds of particulate matter after crushing waste materials.

[0002]

[Technical background] Various types of waste are crushed not only when they are recycled but also when they are incinerated or landfilled.
It must be a certain size. Preferably, it should be granular. If it is large, handling at the time of incineration and landfill is inconvenient, and management of the incineration state becomes complicated, and
This is because there are many voids and effective landfilling cannot be performed.

The crushed waste is once stored in the hopper and then appropriately transported to the intended processing site. The storage hopper P generally has a shape shown in FIG. 6, and a supply chute (supply pipe) 1 is connected to the upper surface of the storage hopper P so that the crushed particulate matter a from a crusher or the like can remove the chute 1. Sent through. The stored material a is appropriately discharged through the gate 3.

During this feeding, the chute 1 may be attached to the upper surface of the storage hopper P while being inclined with respect to the upper surface of the storage hopper P, as shown in the figure, due to the structure of the equipment and the transportability (transportability).

[0005]

When the granular material a is sent to the storage hopper P by the inclined chute 1, the storage shape and capacity in the hopper P change depending on the feeding amount and speed. That is, if it is fast, it is biased to the front A zone side and is not stored in the B zone side. Also,
If the feeding amount is large, B is caused by the interference between the granular materials a.
Although it is also fed to the zone, it is also biased to the A zone side, and if the feed amount is small, most of it is fed to the A zone side.

Therefore, when the granular material a is fed into the hopper P by the inclined chute 1 of this type, as shown in FIG. In this biased storage state, an unbalanced load is applied to the hopper P, which may cause deformation of the hopper P.

In addition, the reservoir in the A zone is the supply port 2
If it is closed, it cannot be stored any more, and although it has a sufficient storage space in the B zone, it cannot be stored. That is, the biased storage reduces the effective storage amount with respect to the entire capacity of the hopper P.

By the way, as shown by the chain line in FIG.
If you feed straight to the center of the upper surface of the hopper P,
Although each of the above problems can be solved to some extent, in some cases, as described above, the shoot 1 must be inclined.

Under such circumstances, it is an object of the present invention to eliminate uneven storage in the hopper and increase the effective storage amount.

[0010]

In order to solve the above-mentioned problems, in the present invention, there is provided a supply section structure in which a downwardly inclined chute is guided to the center of the upper surface of the storage hopper, and the inclined chute is connected to the storage hopper. Above the supply port, a downward repulsion gate plate is provided that crosses the supply path of the inclined chute, and the repulsion gate plate passes through the supply port and reaches the required position in the storage hopper, and at the same time, is required in the vertical direction. The construction is such that the angle can be adjusted and fixed (claim 1).

In this structure, the frame of the inclined chute is provided with a horizontal rotation shaft, the upper edge of the repulsion gate plate is fixed to the rotation shaft, and the arm orthogonal to the rotation shaft is fixed. By connecting a means for rotating and fixing the arm to the arm, the repulsion gate plate can be adjusted and fixed at a required angle (claim 2).

It is preferable that the repulsive gate plate can be adjusted in vertical length.

[0013]

According to the present invention thus constructed, the arm of the rotary shaft is rotated to rotate and fix the repulsion gate plate at a required angle, and the particulate matter (reservoir) sent from the chute is transferred to the repulsion gate plate. Make sure it hits and falls to the required position in the hopper.

That is, in the initial stage of storage, the repulsive gate plate is projected from the chute to the front side of the supply port (see the solid line state in FIG. 2) and is stored to the front side of the inclined chute of the hopper. As the storage proceeds, the repulsion gate plate is gradually retracted (in the direction of the chain line in FIG. 2) so that it is uniformly stored in the entire area of the hopper.

At this time, the length of the repulsion gate plate is adjusted according to the size and properties of the stored material. This is because if it is too long, a large object will have a larger contact portion and will not smoothly fall into the hopper.
