To achieve these goals, the utility model provides a kind of chute blockage checking system, this checking system comprises: cover plate, be installed on the lateral opening place of coal breakage bucket, when there is chute blockage in described coal breakage bucket, coal overflows from described opening part, thus promotes described cover plate and move to the direction away from described coal breakage bucket; And proximity switch, be arranged on the predetermined position apart from described cover plate, when described cover plate moves to the direction away from described coal breakage bucket, described cover plate near described proximity switch, this proximity switch action.
Preferably, described checking system also comprises: warning device, is electrically connected with described proximity switch, sends warning when described proximity switch action.
Preferably, described cover plate is dustpan shaped cover plate.
Preferably, described checking system also comprises: connecting device, and this connecting device comprises: upper junction plate, is fixed on the top position place of described opening; And hinge, described cover plate is connected with described upper junction plate by this hinge.
Preferably, described checking system also comprises: support, is arranged on around described opening, for fixing described proximity switch.
Correspondingly, the utility model also provides a kind of coal conveyer belt equipment, and this coal conveyer belt equipment comprises above-mentioned chute blockage checking system.
By technique scheme, use cover plate and proximity switch composition chute blockage checking system, cost is low, long service life, relative to chute blockage switch or the chute blockage checking system of other type, there is not the situation being smashed and clear up sticky coal by coal cinder, and adjustment is very simple.
Other features and advantages of the utility model are described in detail in detailed description of the invention part subsequently.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for specification sheets, is used from explanation the utility model, but does not form restriction of the present utility model with detailed description of the invention one below.In the accompanying drawings:

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
Fig. 1 shows the structural representation of the chute blockage checking system that the utility model provides.As shown in Figure 1, the chute blockage checking system that the utility model provides, this system comprises: cover plate 4, be installed on lateral opening 6 place of coal breakage bucket, when chute blockage appears in described coal breakage bucket, coal overflows from described opening 6, thus promotes described cover plate and move to the direction away from described coal breakage bucket; And proximity switch 1, be arranged on the predetermined position apart from described cover plate 4, when described cover plate moves to the direction away from described coal breakage bucket, described cover plate 4 near described proximity switch 1, this proximity switch 1 action.
Wherein, the top at lateral opening 6 place of coal breakage bucket can be fixed in side by cover plate 4 by connecting device, this connecting device comprises: upper junction plate 5, is fixed on the top position place of described opening 6; And hinge, described cover plate 4 is connected with described upper junction plate 5 by this hinge 2, and then cover plate 4 is covered and is close to opening 6.
Proximity switch 1 can be fixed on the predetermined position of distance cover plate 4 by support 3, this support 3 can be installed on distance cover plate 4 appropriate position around cover plate 4, such as, the left side (as shown in fig. 1) of cover plate 4, right side or appropriate position, downside can be arranged on.In addition, proximity switch 1 and coal breakage bucket or and cover plate 4 between distance can be set to adjustable.
