DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1 and 2 As shown, a diversion and debris picking device for coal mines includes a main conveyor 1 for conveying raw coal, a mounting frame 12 is fixedly provided above the main conveyor 1, and at least one first diverter plate 2 and at least one second diverter plate 3 are fixedly connected to the bottom of the mounting frame 12, the first diverter plate 2 and the second diverter plate 3 are both perpendicular to the main conveyor 1, the first diverter plate 2 is close to the incoming end of the main conveyor 1, the distance between the first diverter plate 2 and the main conveyor 1 is greater than the distance between the second diverter plate 3 and the main conveyor 1, and an angle is left between the first diverter plate 2 and the second diverter plate 3 and the conveying direction of the main conveyor 1, and a plurality of sorting robotic arms 8 for sorting the raw coal diverted by the first diverter plate 2 and the second diverter plate 3 are provided on the side of the main conveyor 1.

[0023] After mining, raw coal is transported via the main conveyor 1. When the raw coal reaches the first diverter plate 2, raw coal and debris with a volume exceeding the first threshold are blocked by the first diverter plate 2 and then move along the surface of the first diverter plate 2, being diverted by the first diverter plate 2. Coal and debris with a volume less than the first threshold can pass under the first diverter plate 2. When the raw coal reaches the second diverter plate 3, raw coal and debris with a volume exceeding the second threshold but less than the first threshold are diverted by the second diverter plate 3, while raw coal and debris with a volume less than the second threshold can pass under the second diverter plate 3. The raw coal diverted by the first and second diverter plates 2 and 3 is diverted in different directions, thereby achieving preliminary screening of large-volume raw coal and debris. Afterwards, the sorting robot 8 sorts the diverted raw coal, removing coal with a volume exceeding the first threshold and coal with a volume between the first and second thresholds from the main conveyor 1, thus achieving thorough sorting of the large-volume raw coal and debris. Because the large volume of raw coal and debris has been preliminarily screened by the first diversion plate 2 and the second diversion plate 3 and diverted to different locations, the sorting robot 8 only needs to be able to grab the large volume of raw coal and debris after diversion. The range of action is smaller, easier to control, and the action time is shorter, and the sorting efficiency is higher.

[0024] In this embodiment, two first diverter plates 2 are provided. The distance between the two first diverter plates 2 gradually increases from the inlet end to the discharge end of the main conveyor 1, and one of the first diverter plates 2 is located near the inlet end of the main conveyor 1. A first conveying area 5 is formed between the first diverter plates 2 and the edge of the main conveyor 1. The first conveying area 5 corresponds to at least one sorting robot arm 8. After being screened by the two first diverter plates 2, raw coal and debris with a volume reaching a first threshold are diverted to locations near the two sides of the main conveyor 1. Because raw coal and debris with a volume reaching the first threshold have the largest mass, diverting them to the edge of the main conveyor 1 can reduce the travel distance of the sorting robot arm 8 during the process of transferring this portion of raw coal and debris, thereby reducing the load on the sorting robot arm 8. In addition, the two first diverter plates 2 are arranged one after the other along the conveying direction of the main conveyor 1 to prevent raw coal and debris with a volume reaching the first threshold from becoming stuck between the two first diverter plates 2. If the raw coal and debris whose volume reaches the first threshold value fail to move smoothly along the first diverter plate 2 at the previous first diverter plate 2 , they can also be diverted at the next first diverter plate 2 .

[0025] Similar to the first diverter plate 2, in this embodiment, two second diverter plates 3 are provided. The distance between the two second diverter plates 3 gradually increases from the incoming material end to the outgoing material end of the main conveyor 1. One of the second diverter plates 3 is located near the incoming material end of the main conveyor 1. The two second diverter plates 3 are located on the side of the two first diverter plates 2 facing the outgoing material end of the main conveyor 1. A second conveying area 6 is formed between the second diverter plates 3 and the first conveying area 5. The second conveying area 6 corresponds to at least one sorting robot arm 8. The distribution and configuration of the two second diverter plates 3 are the same as those of the first diverter plates 2 and will not be repeated here.

[0026] Furthermore, a diverter bar 4 is fixedly connected to the bottom of the mounting frame 12. The diverter bar 4 is perpendicular to the main conveyor 1, and the distance between the diverter bar 4 and the main conveyor 1 is less than the distance between the second diverter plate 3 and the main conveyor 1. The diverter bar 4 is located above the third conveying area 7, and the third conveying area 7 is located between the two second conveying areas 6. The diverter bar 4 is used to disperse the raw coal and debris whose volume does not reach the second threshold, to prevent the raw coal and debris whose volume does not reach the second threshold from passing between the two second diverter plates 3 from being distributed in large quantities in the middle position of the main conveyor 1, resulting in excessive movement of the sorting robot arm 8, so as to reduce the load on the sorting robot arm 8. Accordingly, the diverter bar 4 should be located above the centerline of the main conveyor 1.

[0027] Based on the above-mentioned first diverter plate 2, second diverter plate 3 and diverter lever 4, multiple conveying areas are formed on the main conveyor 1, and each conveying area corresponds to at least one sorting robot arm 8, so that the sorting robot arm 8 only needs to sort out the raw coal and debris in the corresponding conveying area. The coverage range of the sorting robot arm 8 is effectively reduced, and the load of the sorting robot arm 8 is also effectively reduced.

[0028] The first diverter plate 2, the second diverter plate 3, and the diverter baffle 4 are all fixedly connected to the mounting frame 12 via at least one suspension rod 13. The mounting frame 12 can be supported by a bracket structure disposed to the side of the main conveyor 1; the mounting frame 12 can also be supported by a hoisting structure disposed on the ceiling of the laneway, both of which are conventional techniques in the art and will not be described in detail here.

[0029] The sorting robot 8 is configured as follows: multiple bases 10 are fixedly mounted on either side of the main conveyor 1, with the sorting robot 8 mounted on each base 10. All bases 10 on the same side of the main conveyor 1 are connected to a connecting rod 11, secured by multiple anchor bolts. The coordination of the bases 10 and connecting rods 11 enhances the stability of the sorting robot 8, ensuring long-term, stable operation.

[0030] In order to facilitate the transportation of the sorted large-volume raw coal and debris to different locations for subsequent processing, multiple auxiliary conveyors 9 are arranged on the side of the main conveyor 1. The auxiliary conveyors 9 correspond to at least one sorting robot arm 8. The auxiliary conveyors 9 are used to transport the raw coal sorted by the sorting robot arm 8.

[0031] like Figure 3 As shown, considering that the contact between the raw coal and the first diverter plate 2 and the second diverter plate 3 will cause wear of the first diverter plate 2 and the second diverter plate 3, in order to extend the service life of the first diverter plate 2 and the second diverter plate 3, the first diverter plate 2 and the second diverter plate 3 are both integrally connected with an extension plate 14, and the extension plate 14 is detachably connected with a wear-resistant lining plate 15. The wear-resistant lining plate 15 is parallel to the first diverter plate 2 or the second diverter plate 3, and the wear-resistant lining plate 15 faces the incoming material end of the main conveyor 1. The wear-resistant lining plate 15 can be made of the same wear-resistant nylon material as the wear-resistant lining for the underground hoist. The specific fixing method of the wear-resistant lining plate 15 is: the wear-resistant lining plate 15 is fixedly connected to the extension plate 14 by a plurality of fixing bolts 17, and the wear-resistant lining plate 15 is provided with a receiving hole 16 for accommodating the head of the fixing bolt 17.

[0032] Finally, it should be noted that the method for the sorting robot arm to identify and grab large volumes of raw coal and debris can adopt a method based on machine vision, which is a mature existing technology and will not be repeated here.

[0033] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0034] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
