Problems solved by technology

[0002] When the shearer is mining coal in the coal mine, on the one hand, it is inevitable that some floating coal will remain between the scraper conveyor and the coal wall working face. It is a method to push the coal onto the scraper and then transport it away, but when the amount of floating coal in a certain place reaches a certain amount, it may affect the efficiency of the scraper conveyor moving forward, which will cause disadvantages to the coal mining face. On the other hand, when the shearer runs to the end of the scraper conveyor, the coal that is thrown out by the rotation of the shearer drum and naturally collapsed will scatter down, and these floating coals are not successfully loaded onto the scraper conveyor , and with the continuous advancement of the working face, the amount of floating coal will gradually increase. If it is not cleaned in time, it will affect the coal mining efficiency. For these floating coals, the main cleaning method is to rely on manual cleaning machinery to complete, but in thin When coal seam is mined, due to the narrow space of the roadway, it is difficult to clean the floating coal, the work efficiency is low, and there are also potential safety hazards

Embodiment 1

[0061] A mobile inspection floating coal cleaning system, such as Figure 1-5 As shown, the car body 2 is included, and the car body 2 is provided with a sliding system, a machine vision and control system 3, a rotating system 19 and a coal shoveling system;

[0062] The sliding system is arranged under the car body 2, and is used to cooperate with the scraper conveyor to realize the front and rear movement of the car body. The rotating system 19 can rotate back and forth relative to the car body 2. The coal shoveling system is arranged on one side of the car body 2, and is connected Rotary system 19 is connected for shoveling coal;

[0063] Machine vision and control system 3 includes interconnected PLC controller and machine vision system, which is protected by a protective shell outside. The machine vision system is used to continuously collect images to judge the timing of execution actions, and transmit signals to the PLC controller. PLC The controller is connected with ...

Embodiment 2

[0065] A mobile inspection type floating coal cleaning system, the structure is as shown in embodiment 1, the difference is that the machine vision system includes a visual sensor, a high-speed image acquisition system, a special graphics processing system and a computer, and the computer is connected to a PLC controller;

[0066] The visual sensor includes an image sensor and a light projector. The image sensor is used to collect the distance between the car body and the end of the coal shearer or scraper conveyor and the height of the floating coal seam in real time. The light projector is used to supplement light for the image sensor so that the image sensor The image can be received more clearly, the image sensor and the light projector are embedded in the interior of the car body 2, and the exterior is protected by toughened glass;

[0067]The analog video signal collected by the visual sensor is transmitted to the high-speed image acquisition system. The high-speed image ...

Embodiment 3

[0078] A mobile inspection type floating coal cleaning system, the structure of which is shown in Embodiment 2, the difference is that the visual sensor also includes a laser radar sensor 16, and the laser radar sensor 16 is located on the coal shoveling system for detecting coal mining face The distance from the bucket of the coal shoveling system to avoid collisions when shoveling coal.

[0079] Utilizing the detection distance of the laser radar sensor 16 is the prior art. When the bucket is moved forward to charge coal, the laser radar sensor constantly detects the distance between the laser radar sensor itself and the coal mining face, and then knows the distance between the bucket and the coal wall. The distance between buckets is compared with the set value in the PLC controller. When the distance decreases to the set value, the bucket stops advancing.
