[0001] This invention belongs to the field of belt conveyor cleaning technology, specifically a patting device for belt conveyors, and particularly relates to a device for managing the return material on large-angle corrugated belts. Background Technology

[0002] Belt conveyors are friction-driven systems that transport loose materials or packaged goods. They are widely used in coal mines, power plants, cement plants, coal preparation plants, ports, boilers, coking plants, and non-ferrous metal industries.

Detailed Implementation

[0045] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Example 1

[0047] Please see Figure 1 - Figure 6 This application provides a tapping device for a belt conveyor, comprising:

[0048] A fixed base plate 100 is installed inside the belt conveyor frame;

[0049] The beating mechanism 200 installed inside the fixed base plate 100 automatically cleans residual materials in the grooves of the large-angle corrugated belt by utilizing the reciprocating motion and vibration effect generated by the beating mechanism 200 on the belt surface. It can continuously clean residual materials in the belt grooves without stopping the machine or reducing the efficiency of the conveying system. The operation and stop of the beating cleaning device are precisely controlled by the electronic control system to achieve fully automatic operation and ensure operational safety. This device not only improves cleaning efficiency and reduces manual intervention, but also reduces maintenance costs and extends service life due to its simple structure, stable operation, and strong adjustability. Therefore, it has significant application value in the field of industrial material handling. The beating mechanism 200 includes a roller component 201 that is rotatably installed inside the fixed base plate 100 to vibrate and beat the inner surface of the belt, a driving component 204 that drives the roller component 201 to rotate, a connecting rod component 203 that makes the roller component 201 move repeatedly, and a pushing component 205 that pushes and cleans the outer surface of the belt.

[0050] In this embodiment, preferably, the roller component 201 that strikes the inner surface of the belt includes:

[0051] A stabilizing base 2013 is fixed to the lower surface of the fixed base plate 100. A fixed shaft 2012 is provided through the inside of the stabilizing base 2013 to support the fixed shaft 2012.

[0052] 2011, a slapping roller used to strike and beat the inner surface of a belt;

[0053] A connecting plate 2014 is fixed to the surface of the slapping roller 2011 and rotatably sleeved on the fixed shaft 2012 at the other end. The connecting plate 2014 can rotate around the fixed shaft 2012, so that the slapping roller 2011 moves back and forth with the connecting plate 2014.

[0054] In this embodiment, preferably, the drive component 204 that provides power to the beating roller 2011 includes:

[0055] Two bearing seats 2044 are fixed on the lower surface of the fixed base plate 100. A drive shaft 2043 is rotatably installed inside the bearing seat 2044. One drive shaft 2043 is connected to the reducer 2042, and the other drive shaft 2043 is connected to the pusher component 205.

[0056] The reducer 2042, which is installed on the outer surface of the bearing housing 2044, can adjust the speed of the drive shaft 2043 to ensure that the operating frequency of the beater roller 2011 matches the belt conveying speed. The drive motor 2041 is provided on the rear surface of the reducer 2042.

[0057] In this embodiment, preferably, the connecting rod component 203 rotates with the transmission shaft 2043, causing the eccentric wheel 2033 and eccentric shaft 2034 to rotate, which in turn drives the lower support 2035 to rotate, moves the connecting rod component 2036, causes the upper support 2031 to deflect, and drives the beater roller 2011 to reciprocate around the fixed shaft 2012. The connecting rod component 203 that drives the beater roller 2011 to reciprocate includes:

[0058] The upper support 2031 is rotatably sleeved on the end of the beater roller 2011, and a connecting rod 2036 is provided on the lower surface of the upper support 2031.

[0059] An eccentric wheel 2033 is installed at the inner end of the drive shaft 2043, and an eccentric shaft 2034 is provided on the inner surface of the eccentric wheel 2033.

[0060] A lower support seat 2035 is sleeved on the eccentric shaft 2034, and a connecting shaft 2032 is provided between the two lower support seats 2035 so that the two lower support seats 2035 rotate synchronously, thereby driving another transmission shaft 2043 to rotate.

[0061] In this embodiment, preferably, a pushing member 205 for pushing material onto the outer surface of the belt is provided at the outer end of the leftmost drive shaft 2043. Using the pushing member 205, material on the outer surface of the belt can be pushed and collected towards the edge while the belt is vibrating and patting. The pushing member 205 includes:

[0062] A vertical shaft 2051 is vertically installed on the outside of the fixed base plate 100. A rotating component for driving the vertical shaft 2051 to rotate is provided at the outer end of the transmission shaft 2043. The rotating component includes a fixed worm gear 2057 fixedly sleeved on the vertical shaft 2051 and a driving worm 2058 sleeved on the outer end of the transmission shaft 2043. The driving worm 2058 meshes with the fixed worm gear 2057.

[0063] An upper fixing plate 2052 is installed on the upper end of the vertical shaft 2051. The upper fixing plate 2052 can rotate synchronously with the vertical shaft 2051. A sleeve 20510 is embedded in one end of the upper fixing plate 2052. The sleeve 20510 is sleeved on the vertical shaft 2051, and a limit bolt is provided between the two to facilitate the disassembly and assembly of the sleeve 20510 and the upper fixing plate 2052. The vertical shaft 2051 can be set as an electric telescopic rod to facilitate changing the height of the upper fixing plate 2052 and to adapt to the position of the belt. A reciprocating plate 2053 is rotatably provided on the upper surface of the free end of the upper fixing plate 2052.

[0064] A drive cylinder 2054 is installed on the upper surface of the reciprocating plate 2053. A support cylinder seat 20541 is provided on the upper surface of the reciprocating plate 2053 to support the drive cylinder 2054. The support cylinder seat 20541 is U-shaped and located outside the waist-shaped hole 20591. It does not affect the sliding of the guide wheel 20592 in the waist-shaped hole 20591. A pusher brush 2056 is provided at the free end of the piston rod inside the drive cylinder 2054, which can move with the extension and retraction of the piston rod.

[0065] In summary, during use, the entire beating device is installed within the belt conveyor frame. The beating roller 2011 is located inside the belt. When the belt conveys material, the drive motor 2041 operates, driving the connected reducer 2042 and drive shaft 2043. The drive shaft 2043 drives the eccentric wheel 2033 and eccentric shaft 2034 to rotate, thereby driving the connecting rod assembly 203. The connecting rod assembly 203 drives the beating roller 2011 to reciprocate around the fixed shaft 2012 at a certain frequency. The force acts on the belt, causing it to vibrate. This vibration shakes the material in the grooves out onto the belt for continued transport. During material transport, the vertical shaft 2051 and the fixed support rod 20593 extend simultaneously and are positioned above the belt, preventing the normally transported material from being pushed to the side. After material transport is completed, some material may still remain on the belt surface. At this point, the vertical shaft 2051 and the fixed support rod 20593 can be retracted simultaneously. The pusher brush 2056 is located on the outer surface of the belt and, as the drive shaft 2043 rotates, drives the drive... The moving worm gear 2058 rotates, causing the fixed worm wheel 2057 and the vertical shaft 2051 to rotate, which in turn drives the upper fixed plate 2052 to rotate. The free end of the upper fixed plate 2052 drives the reciprocating plate 2053 to deflect outward around the guide wheel 20592. When the reciprocating plate 2053 moves outward, the piston rod inside the drive cylinder 2054 extends, positioning the pusher brush 2056 on the left side. Collection mechanisms 300 can be installed on both sides of the belt, and these collection mechanisms 300 do not affect the movement of the reciprocating plate 2053, allowing it to approach the pusher brush. The opening of the collection box 301 in the collection mechanism 300 of component 205 can face upwards to facilitate material feeding. When the reciprocating plate 2053 moves to the right, the piston rod inside the drive cylinder 2054 extends and drives the pusher brush 2056 to approach the right side of the belt, so that the material is collected by the collection box 301 on the right side. In the whole process, the material stuck on the belt can be collected as much as possible, reducing material waste. When the material is being transported normally, the vibrating belt prevents the material from adhering to the inner surface of the belt groove, improving cleaning efficiency and reducing manual intervention.

[0066] Example 2

[0067] Reference Figure 6 and Figure 7 This is the second embodiment of the present invention.

[0068] In this embodiment, preferably, the upper surface of the fixed base plate 100 is provided with a support member 2059 for supporting the reciprocating plate 2053. The support member 2059 neither affects the movement of the reciprocating plate 2053 nor its deflection, while providing support and ensuring stable movement of the reciprocating plate 2053. This, in turn, drives the upper drive cylinder 2054 to work stably to clean the material from the belt surface. The support member 2059 includes:

[0069] The reciprocating plate 2053 has an oblong hole 20591 on its surface along its length. The oblong hole 20591 is long enough to facilitate the sliding of the guide wheel 20592. The guide wheel 20592 is slidably arranged inside the oblong hole 20591. The guide wheel 20592 is circular when viewed from above and H-shaped when viewed from the front, so that the guide wheel 20592 can slide in the oblong hole 20591 without falling off.

[0070] A fixed support rod 20593 is fixed between the upper surface of the fixed base plate 100 and the lower surface of the guide wheel 20592. The fixed support rod 20593 can be electrically telescopically adjustable to facilitate the adaptation of the electrically telescopically adjustable vertical shaft 2051. The fixed support rod 20593 supports the guide wheel 20592 and the reciprocating plate 2053.

[0071] In summary, the guide wheel 20592 is located in the oblong hole 20591. As the reciprocating plate 2053 moves, the guide wheel 20592 can always slide in the oblong hole 20591. Part of the reciprocating plate 2053 always slides in the annular groove of the guide wheel 20592, supporting the reciprocating plate 2053 while preventing the guide wheel 20592 from disengaging from the reciprocating plate 2053. The reciprocating plate 2053 moves left and right along the guide wheel 20592, thereby driving the drive cylinder 2054 on it to move and push the material stuck on the outer surface of the belt to the edge for collection.

[0072] In this embodiment, preferably, the free end of the piston rod inside the drive cylinder 2054 is provided with a long plate 2055, and the pusher brush 2056 is provided on the lower surface of the long plate 2055, so that the long plate 2055 and the pusher brush 2056 can move with the extension and retraction of the piston rod.

[0073] Example 3

[0074] Reference Figure 2 and Figure 8 This is the third embodiment of the present invention.

[0075] In this embodiment, preferably, a collection mechanism 300 located outside the belt is provided on the upper surface of the fixed base plate 100. By providing the collection mechanism 300, it can cooperate with the pushing component 205 to collect the material stuck on the belt, preventing the material from remaining on the belt indefinitely, increasing the cleanliness of material collection, and at the same time, the collected material is less likely to fall out of the collection box 301 again, avoiding waste of material stuck on the belt. The collection mechanism 300 includes:

[0076] The collection box 301 is located horizontally on the outside of the belt. The collection box 301 has an L-shaped hollow structure. The side of the collection box 301 near the belt has a feed port. The surface of the collection box 301 has a notch for the edge of the belt to be placed, so as to facilitate the subsequent material to be pushed into the collection box 301.

[0077] A dustproof layer 304 is installed on the inner surface of the feed inlet. The dustproof layer 304 can be the cloth layer of the funnel. When no external force is applied, the cloth layer will fall down, causing the rectangular feed inlet to close. This prevents external impurities from entering and prevents the collected material from being discharged again. The inner corners of the dustproof layer 304 are inclined, so that the material entering the collection box 301 falls along the inclined surface to the bottom of the collection box 301. The collection box 301 is located on the outer side of the end of the roller beater 201. A protrusion can be provided at the end of the roller beater 201. As the roller beater 201 beats the inner surface of the belt, it can drive the protrusion to move and vibrate the inclined surface of the collection box 301, causing the inclined surface to vibrate and the material to fall quickly to the bottom of the collection box 301. A rectangular feed inlet is opened on the surface of the dustproof layer 304.

[0078] In this embodiment, preferably, the bottom of the collection box 301 is provided with a discharge port, and a discharge plate 302 is provided in the discharge port to facilitate the subsequent discharge of the material collected at the bottom of the collection box 301.

[0079] In this embodiment, preferably, a rectangular notch 202 is provided on the surface of the fixed base plate 100 for the roller component 201 to move up and down, and a stand 303 is provided between the outer surface of the collection box 301 and the fixed base plate 100 to support the collection box 301.

[0080] In summary, the pusher brush 2056 pushes the material on the belt toward the collection box 301, opens the dustproof layer 304, and pushes the material from the rectangular opening on the surface of the dustproof layer 304 into the collection box 301. The material then enters the bottom of the collection box 301 along the inclined surface. While the roller component 201 vibrates up and down, it contacts the inclined outer surface of the collection box 301, accelerating the entry of the material into the bottom of the collection box 301. When the pusher brush 2056 moves back, it disengages from the dustproof layer 304, and the dustproof layer 304 naturally falls down, closing the rectangular opening again. The whole process is repeated to achieve continuous collection of material on the surface of the belt, and the collected material can be collected through the discharge plate 302.

[0081] Example 4

[0082] This embodiment is obtained by combining Embodiment 1, Embodiment 2 and Embodiment 3.

[0083] The working principle and usage process of this invention are as follows: When the belt conveyor is conveying materials, the roller beater 201 is used to vibrate and beat the inner surface of the belt so that the materials will not remain and adhere to the inner surface of the belt groove. After the material is conveyed, the pusher 205 is used to collect the residual materials on the belt surface as much as possible to reduce material waste. After collection, the trouble of additional belt cleaning is reduced. The cleaned materials are collected by the collection mechanism 300 on the outside of the belt.

[0084] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
