[0026] 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 should not be understood as limiting the present invention.

[0027] Please refer to the following Figures 1 to 3 The invention describes a coal mine electromechanical automatic feeding device according to an embodiment of the present invention.

[0028] like Figures 1 to 3 As shown, the coal mine electromechanical automatic feeding device of the embodiment of the present invention includes: a belt conveying mechanism 1, a base 2, an adjustment mechanism 3 and a cleaning mechanism 4. The belt conveying mechanism 1 includes a conveying frame 11, a belt 12 and a driving assembly 13. The belt 12 and the driving assembly 13 are both arranged on the conveying frame 11. The driving assembly 13 is connected to the belt 12 to drive the belt 12 to rotate relative to the conveying frame 11. The base 2 is installed below the conveying frame 11. The adjustment mechanism 3 is arranged between the conveying frame 11 and the base 2. The adjustment mechanism 3 is used to adjust the inclination angle of the conveying frame 11. The cleaning mechanism 4 includes a water tank 41 and a spray head 42. The water tank 41 is installed on the base 2. The spray head 42 is arranged on the conveying frame 11 and is connected to the water tank 41. The spray head 42 can spray water toward the belt 12.

[0029] According to the coal mine electromechanical automatic feeding device of the embodiment of the present invention, since the adjustment mechanism 3 can adjust the inclination angle of the conveying frame 11, the inclination angle of the conveying frame 11 can be adjusted according to the different loading and unloading heights of the coal mine, so that the belt 12 can transport coal mines of different heights. In addition, since the spray head 42 is arranged on the conveying frame 11 and can spray water toward the belt 12, the coal slag attached to the belt 12 can be removed to improve the conveying efficiency of the coal mine electromechanical automatic feeding device. And since the adjustment mechanism 3 can adjust the inclination angle of the conveying frame 11, the cleaned sewage can be discharged obliquely to the outside of the belt 12 under the action of gravity to avoid the problem of water accumulation in the belt 12. It can be understood that the adjustment mechanism 3 and the cleaning mechanism 4 work together in coordination, so that the coal mine electromechanical automatic feeding device can not only adjust the inclination angle of the conveying frame 11 according to the different loading and unloading heights of the coal mine, but also quickly clean the belt 12, which is conducive to improving the transmission efficiency of the feeding device.

[0030] Optionally, the adjustment mechanism 3 includes a fixed frame 31 and a lifting assembly 32, the fixed frame 31 and the lifting assembly 32 are arranged at intervals along the front-rear direction of the conveying frame 11, the lower end of the fixed frame 31 is fixedly connected to the base 2, the upper end of the fixed frame 31 is pivotally connected to the conveying frame 11, and the lifting assembly 32 includes a lifting drive rod 321 and a rotating shaft seat 322, the lower end of the lifting drive rod 321 is connected to the base 2, the upper end of the lifting drive rod 321 is pivotally connected to the rotating shaft seat 322, and the rotating shaft seat 322 is fixedly connected to the conveying frame 11. It can be understood that the upper end of the fixed frame 31 is hinged to the conveying frame 11, and the upper end of the lifting assembly 32 is hinged to the conveying frame 11 through the adapter seat. When the lifting drive rod 321 is raised and lowered, the pitch angle of the conveying frame 11 and the belt 12 can be adjusted, thereby meeting different conveying conditions of the feeding device, and the structural design is simple and the reliability is high.

[0031] Optionally, there are multiple spray heads 42, which are arranged at intervals along the length direction of the belt 12 and arranged on one side of the width direction of the belt 12. It is understandable that multiple spray heads 42 can spray water at the same time to improve the cleaning efficiency of the belt 12. Since the spray heads 42 are arranged on one side of the width direction of the belt 12, interference with the transportation of the coal mine can be avoided.

[0032] A plurality of spray heads 42 are connected to a water tank 41 via a hose 43, and the water tank 41 is installed in the space between the base 2 and the conveying frame 11. Since the spray heads 42 are connected to the water tank 41 via the hose 43, when the pitch angle of the conveying frame 11 changes, the flexibility of the hose 43 can be used to prevent the hose 43 from being pulled, thereby improving the reliability of the connection between the hose 43, the spray heads 42, and the water tank 41.

[0033] Optionally, the belt 12 is provided with a plurality of blocks 121, which are arranged at intervals along the length direction of the belt 12, and the blocks 121 extend along the width direction of the belt 12, and the extension length of the blocks 121 is substantially consistent with the width dimension of the belt 12. It can be understood that the blocks 121 can assist in promoting the transportation of coal, so as to avoid the problem of coal reflux caused by the excessive inclination angle of the conveying frame 11, which is conducive to improving the conveying efficiency of the belt 12.

[0034] Optionally, the conveyor frame 11 includes a bottom plate 111 and two baffles 112, the belt 12 is wound on the bottom plate 111, the baffle 112 is arranged at the upper end of the bottom plate 111, and the two baffles 112 are respectively arranged on both sides of the width direction of the belt 12. It can be understood that the two baffles 112 can enclose a certain conveying space with the bottom plate 111, and the baffles 112 can stop the coal. Therefore, when the coal is transported, the problem of the coal falling from both sides of the width direction of the bottom plate 111 can be avoided.

[0035] Further, the conveying frame 11 also includes a connecting rod 113 and a plurality of fixing rods 114, the fixing rod 114 extends in the up-down direction and is connected to the baffle 112 and the bottom plate 111, the plurality of fixing rods 114 are arranged at intervals along the length direction of the bottom plate 111, and the connecting rod 113 is connected to the plurality of fixing rods 114. It can be understood that the upper end of the fixing rod 114 is connected to the baffle 112, and the lower end of the fixing rod 114 is connected to the bottom plate 111, thereby improving the firmness of the installation of the baffle 112 and the bottom plate 111. Among them, the connecting rod 113 extends in the length direction of the bottom plate 111 and is sequentially connected to the plurality of fixing rods 114, which can further improve the firmness of the overall installation of the conveying frame 11.

[0036] In some embodiments, the driving assembly 13 includes a driving motor 131 and a conveying roller 132, the conveying roller 132 is connected to the belt 12 by transmission, the driving motor 131 is connected to the conveying roller 132 by transmission, and the belt conveying mechanism 1 also includes an inlet hopper 14 and an outlet hopper 15, both of which are connected to the conveying frame 11, and the driving motor 131 is arranged below the inlet hopper 14. It can be understood that the conveying roller 132 is inserted into the belt 12, and when the driving motor 131 rotates, it can drive the conveying roller 132 to rotate, and under the action of friction, the conveying roller 132 can drive the belt 12 to rotate synchronously.

[0037] Since the drive motor 131 is disposed below the feed hopper 14 , the drive motor 131 can be shielded by the feed hopper 14 to prevent the drive motor 131 from being damaged by falling coal, which is beneficial to improving the reliability of the drive motor 131 during operation.

[0038] For example, the conveying frame 11 further includes a shielding plate 115, which is installed at the end of the conveying roller 132 to hide the conveying roller 132, thereby reducing the risk of the conveying roller 132 getting stuck in coal slag or pinching the operator's fingers.

[0039] Optionally, the driving assembly 13 further includes a protective shell 133 , which is installed on the outside of the driving motor 131 , so that the driving motor 131 can be protected by the protective shell 133 to improve the reliability of the driving motor 131 when it is working.

[0040] In some embodiments, the electromechanical automated feeding device for coal mines further comprises a plurality of wheels 5, and the plurality of wheels 5 are arranged in an array at the lower end of the base 2, thereby facilitating the movement and transportation of the electromechanical automated feeding device for coal mines.

[0041] Optionally, the electromechanical automatic feeding device for coal mines further comprises a limit block 6, which can be switched between a use position and an induction position. In the use position, the limit block 6 is placed on the ground and is engaged with the wheel 5, and in the induction position, the limit block 6 is mounted on the base 2. It can be understood that when the limit block 6 is in use, the limit block 6 can be removed from the base 2 and mounted to the position of the wheel 5, thereby limiting the rotation of the wheel 5 to constrain the position of the electromechanical automatic feeding device for coal mines.

[0042] For example, the limiting block 6 is provided with an arc-shaped matching surface, and the matching surface is in contact with the outer peripheral wall of the wheel 5 to limit the rotation of the wheel 5 .
