Detailed implementation manners

[0017] The following further describes the present invention in detail with reference to the drawings so that those skilled in the art can implement it according to the description in the specification.

[0018] It should be understood that the terms such as "having", "including", and "comprising" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0019] As Figure 1 , 2 shown, the present invention provides a belt cleaning and transfer device, which includes: A baffle 1, which is arranged at the tail of the previous belt; And a collection and transfer assembly 2, which is arranged at the head of the current belt; Wherein, The collection and transfer assembly 2 includes: A C-shaped connecting plate 21, which is fixed to the head of the current belt; A first coal scraping plate 22, which is trapezoidal and arranged at two-thirds of the head of the current belt, and the bottom end is in contact with the surface of the current belt. A connecting rod 23 is hinged between the first coal scraping plate 22 and the C-shaped connecting plate 21, and a resisting spring 24 is sleeved on the connecting rod 23; A second coal scraping plate 25, which is inclined and arranged at one-half of the head of the current belt; A coal scraping and transfer sleeve 26, which is arranged on the C-shaped connecting plate 21, and one end of the coal scraping and transfer sleeve 26 is connected to the first coal scraping plate 22 and the second coal scraping plate 23, and the other end is connected to the baffle 1.

[0020] As Figure 3 and Figure 4 shown, in an embodiment of the belt cleaning and transfer device provided by the present invention, The baffle is of a U-shaped structure and is fixed to the left and right longitudinal beams of the belt conveyor tail through U-shaped clamping legs; The baffle includes a left baffle, a right baffle and a rear baffle; The middle position of the U-shaped clamping leg is a clamping portion that clamps with the longitudinal beam, and both sides are fixed to the edges of the left baffle and the right baffle through bolts.

[0021] The traditional left and right coal baffle and leakage prevention at the belt conveyor tail are converted into adding a rear baffle on the left and right, which eliminates the occurrence of material spillage accidents at the tail of the transport belt conveyor in terms of design.

[0022] As Figure 5 and Figure 6 shown, in an embodiment of the belt cleaning and transfer device provided by the present invention, a positioning plate with a triangular cross-section is arranged on the front side of the baffle, and an arc-shaped baffle is arranged on the front side of the positioning plate.

[0023] As Figure 7 shown, in an embodiment of the belt cleaning and transfer device provided by the present invention, a plurality of short shafts are arranged at the position where the arc-shaped baffle contacts the belt, a triangular roller is fixed to the head end of the short shaft through a bearing, and a rubber ring is attached to the outer surface of the triangular roller.

[0024] The hard friction between the arc-shaped baffle anti-leakage assembly and the transport belt is converted into rolling friction, reducing the frictional resistance when the transport belt starts; preventing the spillage of materials at the belt conveyor tail and extending the service life of the transport belt.

[0025] In an embodiment of the belt cleaning and transfer device provided by the present invention, an electric cleaning brush is further arranged at the head of the current belt conveyor.

[0026] The installation and working process of the present invention are as follows: Firmly connect the U-shaped clamping legs with the left and right longitudinal beams of the L-shaped or straight-line belt transfer machine tail; then connect the baffle with screws through the screw holes; install the triangular positioning plate on the baffle with screws; then install the collection and transfer assembly and the electric cleaning brush; install the arc-shaped baffle on the triangular positioning plate.

[0027] After the installation and fastening work is completed, start the first transport belt from the wellhead in sequence until the last belt at the production working face starts, the shearer starts cutting work, coal is fed to the tail of the last transport belt through the scraper conveyor and the transfer machine, and as the belt runs, the coal is transported from the tail to the head and spilled on the tail of the previous belt.

[0028] The first coal scraping plate scrapes the materials carried on the surface of the belt from above the belt at two-thirds of the cylindrical drum at the head of the belt, and guides them into the tail of the previous belt through the coal scraping transfer sleeve; the second coal scraping plate scrapes the surface of the belt again at one-half of the belt head, and guides the scraped materials into the tail of the previous belt through the coal scraping transfer sleeve; under the action of the abutting spring and the connecting rod, the first coal scraping plate is always in close contact with the conveyor belt.

[0029] To prevent accidents such as the deviation of the conveyor belt caused by unclean belt cleaning, at the same time, the motor of the electric cleaning brush rotates, transmits the power to the speed governor, the brush shaft, the key and the slot, and the cleaning brush rotates to clean the surface of the conveyor belt for further cleaning.

[0030] At this time, all the coal carried by the conveyor belt and the materials adhered to the surface of the belt are guided into the baffle, piled up on the tail of the belt conveyor, and will not be scattered on the floor around the tail of the belt conveyor.

[0031] When the previous conveyor belt is running normally, the materials (coal) scattered at the tail of the belt are transported out of the well through the tail of the previous belt under the combined action of the baffle, the triangular position adjusting plate and the arc-shaped baffle.

[0032] When the previous conveyor belt suddenly stops and the next belt continues to transport materials and fills up the tail of the previous belt, the coal receiving plate of the coal piling alarm system, through the transmission rod, the power receiving plate, the numerical control processing element, etc., cuts off the power supply of the conveyor belt head; while transmitting the stop information to the dispatching room, the conveyor belt stops working. From the design, the occurrence of the accident of burying the tail of the conveyor belt is eliminated. Technically, the scattering of materials at the tail of the belt is prevented, and the labor intensity of the post workers is reduced.

[0033] The present invention integrates belt cleaning, anti-leakage of coal piling at the tail, and emergency stop protection, and can collect and classify the coal at the tail of the conveyor belt to prevent it from being scattered on the bottom plate; when the coal piles up at the tail, it automatically cuts off the rotating power of the next conveyor belt; uses the C leakage coal scraping plate to clean the belt clean.

[0034] The present invention has the following advantages: 1. No matter what state the tail of the conveyor belt is in, the piled coal on the belt will not be scattered on the bottom plate.

[0035] 2. Collect and classify the coal cleaned by the cleaning device at the head of the next belt, and guide it into the tail of the belt through the trough to ensure that it will not fall on the bottom plate.

[0036] 3. Convert the mechanical coal piling protection into a numerical control alarm detection system.

[0037] 4. Convert the hard friction between the coal baffle and the tail of the conveyor belt into rolling friction, and extend the service life of the belt.

[0038] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those skilled in the art, additional modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and the examples shown and described herein.
