[0002] Belt conveyor, also known as coal conveyor, is the most common coal conveying equipment. However, during the coal conveying process, the belt often deviates due to factors such as incorrect coal drop point and uneven coal quantity control, or the coal overflows the bin and the control personnel do not react in time, resulting in a large amount of coal falling onto the non-working surface of the coal conveyor. As time goes by, the coal on the non-working surface of the coal conveyor will not only accumulate more and more, but also cause the coal to fall along the line and fall into the middle of the coal conveyor, resulting in an increase in its counterweight, increasing the difficulty of cleaning for the staff and the dust pollution of this section of the belt. Utility Model Content

[0003] In response to the above problems, the present application provides a coal overflow detection device on the non-working surface of a coal conveyor belt, which solves the problem that during the coal transportation process, due to various factors, coal is easily dropped and accumulated on its non-working surface, resulting in increased counterweight and increased difficulty in cleaning, accompanied by dust pollution.

[0026] In order to more clearly illustrate the technical solutions in the embodiments of the utility model or the prior art, the utility model will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation of the utility model.

[0027] like Figure 1-Figure 4 As shown, an embodiment of the utility model provides a coal overflow detection device for a non-working surface of a coal conveyor belt, comprising a conveyor frame 1, a support leg 2 fixedly mounted at the lower end of the conveyor frame 1, an electric roller 3 rotatably arranged at the opposite side of the conveyor frame 1 and close to the end, and a conveyor belt 4 wound around the outside of the electric roller 3, a lateral coal blocking assembly 5 is symmetrically mounted on the upper end of the conveyor frame 1, and a coal overflow detection assembly 6 is arranged at the lower side of the conveyor frame 1.

[0028] A coal guide plate 11 is obliquely mounted on the side wall of the conveying frame 1 .

[0029] The outer ring of the conveyor belt 4 is evenly provided with coal material partition strips 41 along its circumferential direction.

[0030] The lateral coal blocking assembly 5 comprises a side plate 51 , the upper end surface of the conveying frame 1 is fixedly mounted with the side plate 51 , coal overflow grooves 52 are evenly formed on the side plate 51 , and a coal blocking plate 53 is hingedly connected to the position of the coal overflow groove 52 near the upper end.

[0031] During specific work, coal is manually added to the upper end surface of the conveyor belt 4, and the electric roller 3 is started. The coal is driven by the electric roller 3 to be transported along the upper working surface of the conveyor belt 4. The coal partition bar 41 can automatically isolate the coal, so as to facilitate manual control of the coal conveying amount. The side plate 51 can block the coal, thereby reducing the amount of coal moving to the non-working surface of the conveyor belt 4. When the coal is inevitably offset, the coal will squeeze the coal blocking plate 53 and open it to the outside. At this time, the coal will overflow to the coal guide plate 11 through the coal overflow groove 52, and then fall downward from the coal guide plate 11 to the coal overflow detection component 6.

[0032] The coal overflow detection assembly 6 includes an "L"-shaped rod group 61, and the "L"-shaped rod group 61 is symmetrically arranged on both sides of the lower end surface of the conveying frame 1. The lower end of the "L"-shaped rod group 61 is fixedly connected to a coal collecting box 62. The lower end of the middle part of the coal collecting box 62 is made of elastic material, and wedge blocks 63 are symmetrically installed at both ends of the bottom of the coal collecting box 62. A coal overflow detection unit 64 is fixedly installed in the middle of the lower end surface of the conveying frame 1, and the lower end of the coal overflow detection unit 64 is located below the coal collecting box 62. A cleaning unit 65 is installed on the side wall opposite to the coal overflow detection unit 64 and below the conveying belt 4.

[0033] The coal overflow detection unit 64 includes a vertical plate 641, which is fixedly installed on the middle part of the lower end surface of the conveying frame 1. A rotating rod 642 is installed on the side wall opposite to the vertical plate 641 and deviated from the middle part through a torsion spring. A pressure plate 643 is fixedly connected to the rotating rod 642 at a position close to the vertical plate 641 and located below the middle part of the coal collecting box 62. A detection plate 644 is fixedly connected to the end of the rotating rod 642 away from the pressure plate 643 and on a side different from the pressure plate 643.

[0034] The cleaning unit 65 includes a transverse plate 651, which is fixedly installed on the side wall opposite to the vertical plate 641 and close to the upper end. Flexible bristles 652 are evenly arranged on the upper end surface of the transverse plate 651, and the upper end of the flexible bristles 652 is in contact with the lower end of the conveyor belt 4.

[0035] During specific operation, the coal falls downward along the coal guide plate 11 into the coal collecting box 62. Due to the presence of the wedge block 63, the coal will continue to roll downward along the upper inclined surface of the wedge block 63 to the middle of the coal collecting box 62. Since the lower end of the middle part of the coal collecting box 62 is made of elastic material, it will deform and squeeze the pressure plate 643 downward, while driving the pressure plate 643 and the rotating rod 642 to rotate, thereby driving the detection plate 644 to deflect. At this time, the staff can determine whether coal overflow occurs by observing the offset of the detection plate 644. After the upper end surface of the conveyor belt 4 rotates to the bottom, the flexible brush 652 can clean the conveyor belt 4, thereby removing the coal attached to its surface.

[0036] Working principle: Coal is added to the upper end surface of the conveyor belt 4 manually, and the electric roller 3 is started. The electric roller 3 drives the coal to be transported along the upper working surface of the conveyor belt 4. The coal partition bar 41 can automatically partition the coal, so as to facilitate manual control of the coal conveying amount. The side plate 51 can block the coal, thereby reducing the amount of coal moving to the non-working surface of the conveyor belt 4. When the coal is inevitably offset, the coal will squeeze the coal blocking plate 53 and open it to the outside. At this time, the coal will overflow to the coal guide plate 11 through the coal overflow groove 52, and then fall downward from the coal guide plate 11 to the coal overflow detection component 6;

[0037] The coal falls downward along the coal guide plate 11 into the coal collecting box 62. Due to the presence of the wedge block 63, the coal will continue to roll downward along the upper inclined surface of the wedge block 63 to the middle of the coal collecting box 62. Since the lower end of the middle part of the coal collecting box 62 is made of elastic material, it will deform and squeeze the pressure plate 643 downward, while driving the pressure plate 643 and the rotating rod 642 to rotate, thereby driving the detection plate 644 to deflect. At this time, the staff can determine whether coal overflow occurs by observing the offset of the detection plate 644. After the upper end surface of the conveyor belt 4 rotates to the bottom, the flexible brush 652 can clean the conveyor belt 4, thereby removing the coal attached to its surface.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
