In order to achieve the purpose, the utility model provides the following technical scheme:

the utility model provides a belt conveyor belt anti-tear device, connects in the baffle on belt funnel front end lower edge including rotating, the baffle towards the one end of belt funnel is provided with position sensor, position sensor links to each other with the time delay relay, the lower extreme of baffle is located the belt top, and contactless.

Preferably, the position sensor is of a model 1080-60NUP-KK 0.

Preferably, the model of the time delay relay is JS 14P.

Compared with the prior art, the utility model has the following beneficial effects:

1. the belt anti-tearing device of the belt conveyor can send out a tearing alarm before or when a belt is scratched, so that the belt conveyor is stopped, and the longitudinal scratching and tearing of the belt are prevented.

2. The belt tearing prevention device of the belt conveyor can give an alarm and jump when sundries are blocked at a belt feed opening, and materials are blocked before or when a belt is scratched, so that the belt is prevented from being torn.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention; it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work are within the scope of the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top/bottom", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "sleeved/connected," "connected," and the like are to be construed broadly, e.g., "connected," which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1, a structural schematic diagram that a belt of a belt conveyor is torn by foreign matters in the prior art is shown, in fig. 1, when a foreign matter 4 is clamped in a feed opening, three fulcrums, namely a rear wall of a belt funnel 5, a lower edge of a front wall of the belt funnel 5 and the belt 1, can be stressed on the belt to force the fulcrums to scratch the belt 1, and a supporting roller 2 is arranged below the belt 1, so that an alarm can be given before the belt 1 is scratched as long as an anti-tearing device is arranged at one stress point, the belt conveyor is stopped, and the belt 1 is effectively prevented from being scratched or longitudinally torn. The three fulcrums are analyzed, wherein the positions of the fulcrums of the rear wall of the funnel 5 and the belt 1 cannot be determined, the sizes of foreign matters are different, the positions of the stress fulcrum and the fulcrums are different, and meanwhile, the positions can be changed along with the movement or tearing of the conveying belt, but the lower edge fulcrum of the front wall of the belt funnel 5 is unchanged, so that the fulcrums can be used as mounting points of the anti-tearing device.

For this purpose, as shown in fig. 2-4, the utility model provides a belt tearing prevention device for a belt conveyor, which comprises a baffle 6 rotatably connected to the lower edge of the front end of a belt funnel 5, wherein a position sensor 7 is arranged at one end of the baffle 6 facing the belt funnel 5, the position sensor 7 is connected with a time delay relay 8, and the lower end of the baffle 6 is positioned above a belt 1 and is not contacted.

In the structure of the utility model, the baffle 6 is connected with the lower edge of the front end of the belt funnel 5 in a rotating way, and the position sensor 7 can be connected in a clamping or bolt connection way.

In the present invention, the position sensor 7 is of the type 1080-60NUP-KK 0.

In the mechanism provided by the utility model, a baffle 6 is arranged at the position of a fulcrum under the front wall of the belt funnel 5 or extends forwards and downwards, and the distance between the baffle 6 and the bottom of the belt 1 is increased by 50mm according to the height of materials so as to avoid misoperation. Get into foreign matter 4 and can block in the material at the back wall of belt funnel 5, baffle 6, 1 three points department of belt, move ahead along 1 direction of operation of belt, baffle 6 slope, touch position sensor 5, position sensor 5 gives delay relay 8 with signal transmission, delays 5s delay relay 8 and lasts the received signal, and belt 1 jumps and stops. Therefore, the purpose of preventing the longitudinal scratching and tearing of the belt is achieved, and the false action caused by scratching unit materials by the belt 1 in a large block or without causing the belt is prevented due to the addition of the delay relay 8 (delay 5 s).

The use method and the notes of the utility model are as follows:

the using method comprises the following steps:

get into foreign matter 4 and can block at 5 back walls of belt funnel, baffle 6, 1 three points of belt in the material, move ahead along 1 direction of operation of belt, baffle 6 slope, touch position sensor 7, position sensor 7 gives delay relay 8 with signal transmission, delays 5S delay relay 8 and lasts received signal, and the belt jumps and stops.
