Description

  The present invention relates to a conveyor chute.

If a transported object such as ore adheres to the inner peripheral surface of the conveyor chute and gradually accumulates, the transported object will stay. Therefore, the receiving plate is suspended in a swingable position at the position where the conveyed object dropped in the conveyor chute directly hits. There are some which suppress adhesion of the conveyed product or promote peeling of the adhered conveyed product (see Patent Document 1).
Japanese Patent Laid-Open No. 11-189328

However, since it is not always the position where the dropped transported product directly hits in the conveyor chute, in the conventional example described in Patent Document 1, a backing plate is installed. There is a possibility that the transported material adheres to and accumulates at other locations.
An object of the present invention is to suppress an increase in deposits in a conveyor chute with a simple structure.

In order to solve the above-mentioned problem, a conveyor chute according to claim 1 of the present invention includes a side wall including a frame and a sheet-like elastic body attached to the frame.
A conveyor chute according to claim 2 of the present invention is characterized in that the side wall is provided at a position where a conveyed product dropped from the conveyor does not directly hit.

  According to the conveyor chute according to claim 1 of the present invention, when the conveyed product adheres to the inner peripheral surface of the conveyor chute and gradually accumulates, the elastic body bends according to the amount (weight). , Cracks occur in the cured deposits, and the tiles are broken and collapsed. That is, when the deposit reaches a certain amount of accumulation, it naturally peels off due to the flexure of the elastic body, so that an increase in the deposit can be suppressed and the stay of the transported item can be prevented. In addition, the above effect can be obtained with a simple structure in which a sheet-like elastic body is attached to the frame to form the side wall.

  Moreover, according to the conveyor chute | shooting which concerns on Claim 2, the increase in a manufacturing man-hour and cost can be suppressed by limiting to the position where adhesion of a conveyed product occurs easily and forming said side wall. That is, it is because a conventional steel plate can be used in a place where the conveyed object to be dropped directly hits and where the adhesion and accumulation of the conveyed object are difficult to occur due to the impact and vibration.

Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.
FIG. 1 is a schematic configuration of a conveyor chute. The conveyor chute 1 is installed at the head end of the belt conveyor 2 and guides a conveyed object such as ore dropped from the belt conveyor 2 downward.
As shown in FIG. 2, the conveyor chute 1 is formed by surrounding four sides with a frame 3 assembled in a lattice shape and attaching a sheet-like elastic body 4 to the inside thereof. The elastic body 4 has elasticity and is made of, for example, natural rubber as a sealing material. Further, as shown in FIG. 3, the elastic body 4 is fastened to the frame 3 by bolts 5 at several locations on the edge.

Next, the effect of this embodiment is demonstrated.
Conveyed objects such as ore adhere to the inner peripheral surface of the conveyor chute 1 and gradually accumulate. At that time, the elastic body 4 bends according to the amount (weight) of the accumulated deposits. The deposited deposit has already hardened, but due to the bending of the elastic body 4, the deposit is cracked and untied and collapsed. That is, when the deposit reaches a certain amount of deposit, it naturally peels off due to the bending of the elastic body 4. Accordingly, it is possible to suppress an increase in adhered matter and prevent staying of the conveyed product. Further, if an impact or vibration is applied to the elastic body 4 from the outside, the adhered matter that remains stuck can be easily dropped.

  In addition, in the position where the conveyed product dropped in the conveyor chute 1 directly hits, it is considered that adhesion and accumulation of the conveyed product are unlikely to occur due to the impact and vibration, so only the side surface facing this conveying direction (dropping direction) May be formed of a conventional steel plate instead of the elastic body 4, and according to this, an increase in manufacturing man-hours and costs can be suppressed. On the other hand, it is considered that adhesion and accumulation of the conveyed product are likely to occur on the other side surfaces, that is, two surfaces in the width direction and one surface in the reverse direction of the conveyance because the dropped conveyed product is not directly hit. Only the surface is formed of the elastic body 4.

It is a schematic structure of a conveyor chute. It is an overview of a conveyor chute. It is an attachment part of an elastic body.
