[0002] Coal mine electromechanical transportation refers to a way of transporting materials such as ore, ore sand, coal, etc. inside and outside the coal mine by using mechanical equipment and electrical equipment. It mainly improves the transportation efficiency through mechanized means, reduces the labor input, and thus improves the production efficiency of the coal mine. The ways of coal mine electromechanical transportation are mainly divided into two categories: surface transportation and underground transportation.

[0003] Among them, track transportation is one of the main transportation methods in underground mining mines. The main equipment includes tracks, mine cars, traction equipment and auxiliary mechanical equipment, etc. Mine cars can be divided into freight mine cars, personnel cars and special mine cars (such as explosive cars, water trucks) according to their uses. The main mine cars for transportation are fixed car body type, tipping type, side-dumping type, flat car and bottom-dumping type, etc.;

[0004] In the prior art, since the mine car is towed by an electric locomotive to transport the mined coal and other items, and during the transportation of the coal by the mine car, because the coal is usually directly poured into the interior of the mine car, the coal will accumulate inside the mine car and the coal is not leveled. If there is jolting or a slope during the transportation process, it is very easy for the coal to fall from the interior of the mine car. Summary of the Invention

[0005] The purpose of the utility model is to provide a coal mine electromechanical transportation device, which can cause the coal to be transported to continuously rotate due to the continuous rotation of the feeding tray, and evenly fall into the interior of the mine car, avoiding the accumulation of coal at a single position after entering the interior of the mine car and causing the coal to fall when the mine car jolts, so as to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a coal mine electromechanical transportation device, including a mine car, a feeding component is jointly arranged on the upper side and inside of the mine car, the feeding component includes a feeding hopper fixedly connected to the upper side of the mine car, and the feeding hopper is communicated with the mine car;

[0008] Preferably, a plurality of inclined discharge ports are formed in the outer side of the feeding tray, and the plurality of discharge ports are communicated with each other.

[0009] Preferably, a lubricating component is provided inside the mine car, and the lubricating component includes storage cylinders fixedly installed on the upper side of the mine car, and the number of storage cylinders is two.

[0010] Preferably, conveying pipes are communicated with the outer sides of the two storage cylinders respectively, and the two conveying pipes are both communicated with the inside of the mine car. The two storage cylinders are respectively located on the left and right sides of the loading hopper.

[0011] Preferably, baffles are slidably connected to the interiors of the two conveying pipes, and connecting rods are fixedly connected to the sides of the two baffles away from each other.

[0012] Preferably, first magnetic blocks are fixedly connected to the ends of the two connecting rods away from each other, and clamping grooves are formed inside the side walls of the two conveying pipes.

Specific implementation manners

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] The present utility model provides a technical solution:

[0028] Please refer to Figures 1 to 5 , a coal mine electromechanical transportation device, including a mine car 1. A feeding component 2 is jointly provided on the upper side and inside of the mine car 1. The feeding component 2 includes a feeding hopper 21 fixedly connected to the upper side of the mine car 1, and the feeding hopper 21 is communicated with the mine car 1;

[0029] The lower side of the feeding hopper 21 is communicated with a rotating ring 22. The rotating ring 22 is rotatably connected inside the mine car 1. The lower side of the rotating ring 22 is communicated with a discharging tray 23. An annular rack 24 is fixedly connected to the outer side of the rotating ring 22. A driving motor 25 is fixedly installed on the upper side of the mine car 1. The output end of the driving motor 25 is fixedly connected to a gear 26. The gear 26 is rotatably connected inside the mine car 1. The outer side of the gear 26 meshes with the outer side of the annular rack 24.

[0030] A plurality of inclined discharge ports are provided on the outer side of the blanking tray 23, and the plurality of discharge ports are communicated with each other.

[0031] When the baffle 33 moves, it will disengage from the conveying pipe 32, and notches are provided at the lower part of the connecting rod 34.

[0032] By adopting the above technical solution, first, start the driving motor 25 to drive the gear 26 to rotate. Since the gear 26 meshes with the annular rack 24 on the outer side of the rotating ring 22, the annular rack 24 drives the rotating ring 22 and the blanking tray 23 below it to rotate under the feeding hopper 21. Since the feeding hopper 21 is communicated with the rotating ring 22 and the blanking tray 23, after the coal mine enters the inside of the feeding hopper 21, it will directly fall into the inside of the blanking tray 23. And a plurality of discharge ports on the outer side of the blanking tray 23 are inclined. Start the blanking tray 23 to rotate continuously, and the coal mine enters the inside of the mine car 1 in a rotating state. Since the blanking tray 23 rotates continuously, the conveyed coal mine will also rotate continuously and uniformly fall into the inside of the mine car 1, avoiding the coal mine accumulating at a single position after entering the inside of the mine car 1 and causing the coal mine to fall when the mine car 1 bumps.

[0033] Specifically, as Figure 3 and Figure 4 shown, a lubricating component 3 is provided inside the mine car 1. The lubricating component 3 includes storage cylinders 31 fixedly installed on the upper side of the mine car 1, and the number of the storage cylinders 31 is two.

[0034] Conveying pipes 32 are communicated with the outer sides of the two storage cylinders 31, and the two conveying pipes 32 are both communicated with the inside of the mine car 1. The two storage cylinders 31 are respectively located on the left and right sides of the feeding hopper 21.

[0035] Sliding connections are provided between baffles 33 and the interiors of the two conveying pipes 32, and connecting rods 34 are fixedly connected to the sides of the two baffles 33 away from each other.

[0036] First magnetic blocks 35 are fixedly connected to the ends of the two connecting rods 34 away from each other. Card slots 37 are provided inside the side walls of the two conveying pipes 32. A return spring 38 is fixedly connected to the side of the card slot 37 close to the storage cylinder 31, and the other end of the return spring 38 is fixedly connected to the side of the first magnetic block 35 close to the conveying pipe 32.

[0037] Two second magnetic blocks 36 are fixedly connected to the outer side of the rotating ring 22, and the first magnetic block 35 and the second magnetic block 36 repel each other magnetically.

[0038] By adopting the above technical solution, first, while the rotating ring 22 rotates continuously, every time the two second magnetic blocks 36 on its outer side approach the first magnetic block 35, due to the magnetic repulsion between the two, the first magnetic block 35 pushes the connecting rod 34 and the baffle 33. When the baffle 33 disengages from the inside of the delivery pipe 32, the lubricant inside the storage cylinder 31 will enter the mine car 1 through the delivery pipe 32 and the notch below the connecting rod 34, and adhere to the surface of the annular rack 24. After the second magnetic block 36 moves away from the first magnetic block 35, the return spring 38 inside the card slot 37 pushes the first magnetic block 35, causing the baffle 33 to block the connection between the delivery pipe 32 and the storage cylinder 31 again. Since the storage cylinder 31 supplies lubricating fluid to the annular rack 24 while the annular rack 24 rotates continuously, it not only ensures the smooth rotation of the annular rack 24, but also absorbs the heat generated by the annular rack 24, and avoids affecting the service life of the annular rack 24.

[0039] Working principle: First, start the drive motor 25 to drive the gear 26 to rotate and drive the annular rack 24 to rotate. Subsequently, the annular rack 24 drives the rotating ring 22 and the lower blanking plate 23 below it to rotate under the feeding hopper 21. After the coal mine enters the inside of the feeding hopper 21, it will directly fall into the inside of the blanking plate 23. A plurality of discharge ports on the outer side of the blanking plate 23 are inclined. Start the blanking plate 23 to rotate continuously, and the coal mine enters the mine car 1 in a rotating state. While the rotating ring 22 rotates continuously, every time the two second magnetic blocks 36 on its outer side approach the first magnetic block 35, due to the magnetic repulsion between the two, the first magnetic block 35 pushes the connecting rod 34 and the baffle 33. When the baffle 33 disengages from the inside of the delivery pipe 32, the lubricant inside the storage cylinder 31 will enter the mine car 1 through the delivery pipe 32 and the notch below the connecting rod 34, and adhere to the surface of the annular rack 24. After the second magnetic block 36 moves away from the first magnetic block 35, the return spring 38 inside the card slot 37 pushes the first magnetic block 35, causing the baffle 33 to block the connection between the delivery pipe 32 and the storage cylinder 31 again.

[0040] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
