It is provided with a whole 131, a first guider 137, and a power transmission member 139.

The spacing adjustment portion 150 is disposed on the main body frame portion 110, contacts the transport belt 51a when the transported object 10 is not transported, and moves the transport belt 51a when the transported object 10 is transported. It is provided with a spacing rod 151, a rotating shaft 153, and a roller member 155 to receive the rotational force of the operating unit 130 to lift and lower the spaced apart from the operating unit 130.

In the configuration of the damage prevention device 100 for a belt conveyor, the main body frame portion 110 of the damage prevention device 100 for a belt conveyor has a first guider 137 disposed on a first support frame 113, and a first guider 137. 2 A second guider 30 is disposed on the support frame 115 to guide the movement of the power transmission member 139.

5 and 6, selection of the transfer belt 51a and the transfer roller unit 170 according to the presence or absence of the conveyed object 10 carried on the conveyor belt 51a of the belt conveyor damage prevention device 100 It is possible to implement personal contact.

When the transported object 10 is not transported on the transport belt 51a, the damage prevention device 100 for the belt conveyor is in a state in which the operation of the operating unit 130 is stopped, and the weight member of the spacing rod 151 ( 151a) is located at a relatively low height compared to the roller member 155 and the moving member 151b through its own weight.

The damage prevention device 100 for a belt conveyor is such that the roller member 155 is in contact with the lower side of the transport belt 51a as the weight member 151a of the spacing rod 151 is positioned relatively low, thereby causing the transport belt 51a to be damaged. The roller member 155 rotates along the traveling direction.

A separation distance d1 exists between the transfer belt 51a and the transfer roller unit 170, and as the transfer roller unit 170 maintains a stationary operation while the separation distance d1 exists, the friction time with the transfer belt 51a This reduction has the effect of extending its lifespan.

When the belt conveyor 50 is operated in the forward direction while the transported object 10 is not transported on the transport belt 51a, it contacts the roller member 155 of the spacing adjustment part 150 and moves the transport belt through minimal friction. Support and transfer of (51a) can be implemented.

In addition, the weight member 151a of the spacing rod 151 is located at a relatively low height compared to the roller member 155 and the moving member 151b, and the power transmission member 139 receives the rotational force of the operating unit 130. According to the winding movement force, it moves to a position relatively higher than the roller member 155 and the moving member 151b.

The damage prevention device 100 for a belt conveyor is such that the roller member 155 is spaced from the lower side of the transport belt 51a as the weight member 151a of the spacing rod 151 is positioned relatively high, thereby preventing the conveyed material 10 from being moved. Due to the weight, the transport belt 51a and the transport roller unit 170 come into contact with each other, and the transport roller unit 170 rotates along the moving direction of the transport belt 51a.

A separation distance d2 exists between the transfer belt 51a and the roller member 155, and while the separation distance d2 exists, the operation of the transfer roller unit 170 is maintained to support the transfer belt 51a in the moving direction. and guide.

The damage prevention device 100 for the belt conveyor stops the operation of the operation unit 130 when the conveyed object 10 on the transport belt 51a is not transported again, and then returns to the state of FIG. 6 described above, and the belt conveyor 50 ) can proceed to implement operations corresponding to the operation of ).

As a result, the damage prevention device 100 for a belt conveyor is transported on the transfer belt 51a of the belt conveyor 50 by providing a main body frame part 110, an operation part 130, and a spacing adjustment part 150.
