[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.
[0024] Please refer to the following Figure 1 and Figure 2 The present invention describes a coal conveying and transferring device and a coal conveying system according to an embodiment of the present invention.
[0025] like Figure 1 and Figure 2As shown, the coal conveying and transferring device according to the embodiment of the utility model includes: a coal conveying assembly 1, a coal conveying hopper 2 and a detection assembly 3. The coal conveying assembly 1 includes a first coal conveyor 11 and a second coal conveyor 12, the first coal conveyor 11 is arranged above the second coal conveyor 12, the coal conveying hopper 2 includes a hopper body 21 and an observation window 22, the hopper body 21 is provided with a coal inlet 211 and a coal outlet 212, the first coal conveyor 11 is connected to the coal inlet 211, the second coal conveyor 12 is arranged below the coal outlet 212, the observation window 22 is installed on the hopper body 21 and arranged adjacent to the coal outlet 212, when the coal 4 at the coal outlet 212 is abnormally accumulated, the coal 4 can squeeze and open the observation window 22.
[0026] The detection component 3 includes a first sensor 21 and a controller (not shown). The controller is electrically connected to the first sensor 21 and the first coal conveyor 11. The first sensor 21 is arranged on the funnel body 21 and cooperates with the observation window 22. When the observation window 22 is opened, the first sensor 21 can transmit an alarm signal to the controller to shut down the first coal conveyor 11.
[0027] According to the coal conveying and transferring device of the embodiment of the utility model, the first coal conveyor 11 can convey the coal 4 to the hopper body 21 through the coal inlet 211, and then fall into the second coal conveyor 12 through the coal outlet 212 of the hopper body 21. When the coal 4 at the coal outlet 212 is abnormally accumulated, the coal 4 can squeeze and open the observation window 22. When the observation window 22 is opened, the first sensor 21 can transmit an alarm signal to the controller to stop the first coal conveyor 11. In this way, the entire hopper body 21 can be prevented from being blocked by the coal 4, and the problem of "belt compression" caused by the accumulation of coal 4 on the second coal conveyor 12 can be avoided. Therefore, the coal conveying and transferring device of the embodiment of the utility model can effectively detect the coal mine accumulation situation at the coal outlet 212, with high reliability, and can effectively avoid the problem of coal accumulation at the coal outlet 212.
[0028] It is understandable that the first coal conveyor 11 and the second coal conveyor 12 can be belt conveyors, and of course, can also be auger conveyors. The present application does not limit the specific conveying structure of the first coal conveyor 11 and the second coal conveyor 12.
[0029] When an abnormal pile of coal appears at the coal drop port 212 of the hopper body 21, the coal 4 will squeeze the observation window 22 under the action of gravity, and the observation window 22 will be opened under the action of this external force, so that the first sensor 21 can send a corresponding electrical signal to the controller by detecting the opening and closing of the observation window 22. That is, when the observation window 22 is opened, the first sensor 21 can transmit an alarm signal to the controller to power off and stop the first coal conveyor 11. When the observation window 22 is in a closed state, the first sensor 21 transmits an electrical signal to the controller indicating that the first coal conveyor 11 can work normally.
[0030] Optionally, a protruding block 221 is provided on the observation window 22, and the first sensor 21 is a contact switch, which is detachably mounted on the funnel body 21. When the observation window 22 is in a closed state, the contact switch cooperates with the protruding block 221, and when the observation window 22 is in an open state, the contact switch is spaced apart from the protruding block 221. For example, the protruding block 221 can be welded on the observation window 22 to facilitate the processing and manufacturing of the observation window 22. In addition, the coal conveying and transferring device of the embodiment of the utility model sets the first sensor 21 as a contact switch, which has higher reliability and accuracy and lower cost than other sensors such as laser sensors.
[0031] Furthermore, the first sensor 21 is located outside the funnel body 21. That is, the protruding block 221 and the first sensor 21 are both located outside the funnel body 21, so that when the coal 4 is transferred, damage to the protruding block 221 and the first sensor 21 can be avoided, the reliability of the first sensor 21 is ensured, and the service life of the first sensor 21 is extended.
[0032] In some embodiments, the coal conveying and transferring device further includes an alarm (not shown), which is electrically connected to the controller, and when the observation window 22 is opened, the controller can control the alarm to start. For example, the alarm can be a buzzer, and when the coal 4 is abnormally accumulated and causes the observation window 22 to be squeezed open, the first sensor 21 transmits an alarm signal to the controller, and the controller can control the alarm to start, thereby timely reminding the staff, thereby greatly reducing the impact on production time caused by congestion, and providing a strong guarantee for building a safe mine.
[0033] In another example, there are multiple first sensors 21, and the multiple first sensors 21 are arranged at intervals around the circumference of the observation window 22. Therefore, when one first sensor 21 fails, other first sensors 21 can also detect the opening and closing state of the observation window 22, thereby further ensuring the safe operation of the equipment.
[0034] In some embodiments, the detection component 3 also includes a second sensor 32, which is electrically connected to the controller. The second sensor 32 is disposed on the inner side of the hopper body 21, and the second sensor 32 is located between the coal inlet 211 and the coal outlet 212, and is separated from the coal drop path of the coal material 4. For example, the second sensor 32 can be a distance sensor, that is, when the second sensor 32 detects that the height of the coal pile reaches a certain threshold, it can send a transmission alarm signal to the controller to shut down the first coal conveyor 11. The coal conveying and transferring device of the embodiment of the utility model adopts a dual detection method of the first sensor 21 and the second sensor 32 to detect the abnormal coal stacking condition of the coal conveying and transferring device, which can further improve the detection accuracy of the detection component 3, and greatly reduce the probability of accidents such as belt damage, production stoppage, and belt compression caused by congestion in the coal conveying hopper 2.
[0035] A coal conveying system according to another embodiment of the utility model includes the coal conveying and transferring device of the embodiment of the utility model.
[0036] According to the coal conveying system of the embodiment of the utility model, the first coal conveyor 11 can convey the coal 4 to the hopper body 21 through the coal inlet 211, and then fall into the second coal conveyor 12 through the coal outlet 212 of the hopper body 21. When the coal 4 at the coal outlet 212 is abnormally accumulated, the coal 4 can squeeze and open the observation window 22. When the observation window 22 is opened, the first sensor 21 can transmit an alarm signal to the controller to shut down the first coal conveyor 11. In this way, the entire hopper body 21 can be prevented from being blocked by the coal 4, and the problem of "belt compression" caused by the accumulation of coal 4 on the second coal conveyor 12 can be avoided. Therefore, the coal conveying and transfer device of the coal conveying system of the embodiment of the utility model can effectively detect the coal mine accumulation situation at the coal outlet 212, with high reliability, and can effectively avoid the problem of coal accumulation at the coal outlet 212.
