JPS58162410A - Buffering apparatus for lump substance etc. in belt conveyor chute - Google Patents

Abstract

PURPOSE:To prevent generation of damage and troubles etc. in a carrying conveyor because of the impact due to lump substance by installing a rotary drum equipped with a plurality of buffering vanes in a throwing-in port for lump substance in a carrying conveyor, and thus permitting the impact force due to the lump substance to be absorbed by said rotary drum. CONSTITUTION:The mined substance M such as rock, earth, and sand is transported in the horizontal direction by a carrying conveyor 1, and then dropped- down onto the second carrying conveyor 10 installed downward at the terminal end of the carrying conveyor 1 and transported to a prescribed position. In this case, a rotary drum 3 equipped with a plurality of buffering van 5 on the periphery is installed inside a feeding chute 2 installed above the carrying conveyor 10, and the fitting shaft 30 of the rotary drum 3 is connected with a driving apparatus 7, and the both edges of the fitting shaft 30 are supported to be moved up and down. Said buffering van 5 is constituted of three steel rail members 51 connected in the longitudinal direction, and installed and fixed at each position equally divided into 16 parts on the whole periphery of a roll plate 32.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shock absorbing device for a block or the like in a belt conveyor chute used to throw a block or the like onto a conveyor.

Conventionally, at civil engineering construction sites, excavated materials such as earth, sand, rocks, etc. are put onto a conveyor, and then transferred from one conveyor to another conveyor to be conveyed from the mining site to a predetermined collection location. In this case, if the excavated material is a lump, when it is dropped from an upper position onto the conveyor, the falling speed of the lump increases according to the drop, and the impact force of the lump on the conveyor increases significantly. growing.

This damages the conveyor, causing breakdowns and troubles, and reducing the efficiency of civil engineering work.

The present invention provides a rotary drum equipped with a plurality of buffer blades in the input path of the lumps to the transport conveyor, and absorbs the impact force of the lumps with this rotating drum, thereby preventing damage to the transport conveyor due to the impact of the lumps. The purpose of the present invention is to provide a shock absorbing device for lumps, etc., which prevents breakdowns and troubles from occurring.

The present invention will be specifically described below based on embodiments shown in the drawings.

Figure 1 shows the equipment for transporting excavated materials installed at a civil engineering work site. Excavated materials M such as rocks and earth are transported horizontally by a first conveyor (1). Furthermore, at the end of the conveyor (1), there is a second
conveyor d.

It is dropped upward and transported to a designated location.

A shock absorbing device (2) for lumps, etc. according to the present invention is installed on the dropping input path for the mined material M. This buffer device (2
) is equipped with a charging chute (201) above the second conveyor U■, and a rotating drum (3) is installed inside the chute ■.
) and a cleaner (4) corresponding to the length of the drum is provided below the rotating drum (3) at appropriate intervals.

As shown in Fig. 2, the rotating drum (3) has a metal roll plate ■ between the end plates C31+01+ provided on the mounting shaft ■.
At the same time, a plurality of shock absorbers (5) are attached to the surface of the roll plate. Buffer (5) in the illustrated example
is made of steel rail material 511 (511 (51J) connected in the length direction, and is constructed by connecting three pieces of steel rail material (511
The mounting is fixed at each equally divided position.

In Figure 3, the mounting structure of each rail material (511) is shown, and a concave groove (to) is provided in the middle of the mounting position of each rail material (511 (base of 511 @ Sogami) Board■
, and then tighten the retaining plate (2) with a bolt, nut, or other fastener (rounded) that is engaged with the concave groove.

Both ends of the mounting shaft protrude outward from both side walls of the chute ■ and are supported by square bearings +6) +81, and one shaft end is used to drive a hydraulic motor, etc. Device(
7). Each bearing (6) is connected to the table +8) (81) via a cushioning member (81) such as cushion rubber.
It is disposed above the bearing (6) and is vertically slidably supported by guide rails vertically installed on both sides of the bearing (6).

Each table (8) is provided with an adjustment mechanism (9) for adjusting the position of the rotating drum (3) back and forth. The adjustment mechanism (9) in the illustrated example is a position adjustment port for positioning the table (8) back and forth. and a tightening bolt (93).

However, when the drive device (7) is driven to rotate the rotary drum (3) in the direction of the arrow λ shown in FIG. 1, and the mined material M is dropped downward from the first conveyor (1), Mine M increases speed and buffers (5) of rotating drum (3)

)'s downward movement along the guide rail @@, and the shock absorber member υ
It is absorbed by the buffering action of In this way, the kinetic energy of the mined material M is lost due to the collision, and the mined material M is pushed out in the direction of rotation of the rotating drum (3).
and the chute front wall (23+) and fall onto the second conveyor uol.

In addition, the clay contained in the earth and sand adheres to the surface of the rotating drum (3) and accumulates, but when this accumulated layer reaches a predetermined thickness, the cleaner ( 4), it is scraped off and this causes the chute (
2) Clogging inside can be prevented.

As described above, the present invention provides a rotating drum (3) equipped with a shock absorber (5) on the inside of the chute (2) so that the impact force of the falling lumps is absorbed by the rotating drum (3). By doing so, it is possible to prevent breakdowns and troubles from occurring due to damage to the conveyor due to the impact of lumps, and there is no risk of lowering the work efficiency of civil engineering work.

Furthermore, since the rotating drum (3) is rotated in a fixed direction by the drive device (7), the lumps dropped onto the rotating drum (3) are always pushed out in the rotating direction and are correctly delivered to a predetermined position on the conveyor α@. It has excellent effects that achieve the purpose of the invention, such as being able to lower the temperature.
