The present invention relates to a belt conveyor prevention device for improving the transport efficiency and prevention of environmental pollution by simply and efficiently preventing the lower line formation generated in the route changing chute.

일반적으로, 벨트 컨베이어를 통해 이송되는 원료가 루트 변경을 위하여 슈트를 통과할 때, 원료의 조건, 예를 들어 원료의 입도와 비중 및 원료의 종류 등의 조건과 설비조건 등이 편적 발생의 주요 원인이 되고 있다.In general, when the raw material transported through the belt conveyor passes through the chute to change the route, the main causes of the formation of the raw material are the conditions of the raw material, for example, the conditions such as the particle size and specific gravity of the raw material and the type of raw material. It is becoming.

특히, 과다한 량의 원료가 일시에 슈트를 통과하면서 과도한 양의 원료에 의하여 하부라인에 편적이 발생되었다.In particular, as an excessive amount of raw material passed through the chute at a time, the formation of the lower line caused by an excessive amount of raw material.

도 1 및 도 2는 종래의 벨트 컨베이어 이송설비 상태를 나타낸 정면도 및 편적방지용 담파가 슈트 내에 설치된 상태를 나타낸 정면도로서, 선박으로부터 호퍼(1)에 적치된 원료(7)는 그 하부의 공급부를 통해 벨트 컨베이어(2)에 불출 이송되어 루트변경용 슈트(3)를 통과하여 하부라인(101, 141, 201, 401)으로 이송된다.1 and 2 are a front view showing a state of a conventional belt conveyor conveying equipment and a front view showing a state in which the prevention of seizure dampa is installed in the chute, the raw material 7 accumulated in the hopper (1) from the vessel is the supply portion of the lower portion Discharged and conveyed to the belt conveyor 2 through the route change chute (3) to the lower line (101, 141, 201, 401).

상술된 바와 같은 이송 작업 중, 벨트 컨베이어(2)에 실리는 원료(7)의 량은 대략 시간당 2000톤 내외의 많은 양이므로, 이러한 과중한 양의 원료(7)가 루트변경용 슈트(3)를 통과할 때 슈트(3) 내에 설치된 담파(4)의 조정이 불량한 경우 과도한 량의 원료(7)가 편적되었다.During the transfer operation as described above, the amount of the raw material 7 loaded on the belt conveyor 2 is about 2000 tons per hour, so that such an excessive amount of raw material 7 causes the route change chute 3 to be removed.

따라서, 본 발명의 실시예에 따르면, 도 4 및 도 5에 도시된 바와 같이, 벨트 컨베이어(2)에 의해 이송되는 원료(7)가 루트변경용 슈트(3)를 통과할 때, 상기 삼각유도판(17, 18)의 정점을 중심으로 좌측 또는 우측 중 일측으로 상대적으로 많은 양의 원료(7)가 낙하되고, 반대측으로 낙하되는 원료(7)의 양이 상대적으로 적을 경우, 많은 양의 원료(7)가 낙하되는 측의 삼각유도판(17, 18)이 원료(7)의 낙하력에 의해 밀리게 되고, 밀려난 만큼 안내판(11, 12)을 당겨서 낙하되는 원료(7)를 하부 벨트 컨베이어(101)의 중앙으로 유도하는 작용을 한다.Therefore, according to the embodiment of the present invention, as shown in Figs. 4 and 5, when the raw material 7 conveyed by the belt conveyor 2 passes through the route changing chute 3, the triangular induction When a relatively large amount of the raw material 7 falls on one side of the left or right side around the vertices of the plates 17 and 18 and the amount of the raw material 7 falling on the opposite side is relatively small, a large amount of raw material The triangular guide plates 17 and 18 on the side on which the (7) falls are pushed down by the falling force of the raw material 7, and pull the guide plates 11 and 12 to fall as much as they are pushed. It serves to guide the center of the conveyor (101).

따라서, 상술된 내용을 요약하면 다음과 같다.Therefore, the above-mentioned content is summarized as follows.

즉, 하역기의 호퍼(1)로부터 불출되어 벨트 컨베이어(2)에 의해 이송되는 원료(7)가 슈트(3)를 통과하면서 발생되는 편적하기 위하여, 상기 슈트(3)의 중앙 하부에 설치되는 삼각유동판(17, 18)은 축봉이 부착되고 축볼트(15)가 정점에 삽입되어 힌지가능하게 설치된다.That is, a tripod provided at the center lower portion of the chute 3 in order to be generated while the raw material 7 discharged from the hopper 1 of the unloading machine and conveyed by the belt conveyor 2 passes through the chute 3. The flow plates 17 and 18 are attached to the shaft and the shaft bolt 15 is inserted into the apex and hingedly installed.

또한, 유도판(11, 12)은 상기 삼각유도판(17, 18)의 좌측 및 우측의 슈트(3) 벽면에서 축볼트(15)에 의해 축봉이 체결되어 슈트(3) 내부에서 힌지가능하게 설치된다.In addition, the guide plates 11 and 12 are coupled to the shaft bar by the shaft bolts 15 on the left and right side walls of the chute 3 on the triangular guide plates 17 and 18 so as to be hinged in the chute 3. Is installed.

이와 같이, 상기 삼각유도판(17, 18)의 하부에 각각 형성된 체결구(17a,18a)와 유도판(11, 12)에 각각 형성된 체결구(11a, 12a)를 요동가능하게 연결하기 위하여, 링크(14)의 양단에는 체결구(19)가 형성된다.As such, in order to oscillately connect the fasteners 17a and 18a formed at the lower portions of the triangular guide plates 17 and 18 and the fasteners 11a and 12a respectively formed at the guide plates 11 and 12, Fasteners 19 are formed at both ends of the link 14.

따라서, 본 발명에 따르면, 벨트 컨베이어를 통해 이송되는 원료가 루트 변경을 위하여 슈트를 통과할 때, 한 정점을 중심으로 좌우로 요동되도록 슈트 내부에 힌지결합되어 있는 삼각유도판에 의하여, 원료가 통과하는 량에 따라 유도판을 당기거나 밀어줌으로써, 원료를 하부라인 중앙으로 유도하여 원료의 편적을 방지할 수 있으므로, 환경오염의 방지 및 설비 사고의 방지와 이송 효율을 향상시킬 수 있다.Therefore, according to the present invention, when the raw material conveyed through the belt conveyor passes through the chute for changing the route, the raw material passes by the triangular guide plate hinged inside the chute so as to swing left and right about one vertex. By pulling or pushing the guide plate according to the amount, the raw material can be guided to the center of the lower line to prevent the accumulation of raw materials, thereby preventing environmental pollution, preventing equipment accidents, and improving transfer efficiency.

또한, 이송량의 변화가 심한 경우에도 담파를 조정하는 경우에 비해 자동으로 편적이 조정되므로, 편적조정시간이 절약되고, 작업자 안전사고를 예방 할수 있는 장점도 있다.In addition, even when the change in the feed amount is severe, since the knitting is automatically adjusted compared to the case of adjusting the swelling, the adjustment time is saved, there is an advantage that can prevent the worker safety accident.
