DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Reference Figure 1-Figure 9 As shown, the present invention provides a belt pressing device for a mining belt conveyor, comprising a frame 1, and also comprising: a conveyor belt 101, the conveyor belt 101 is installed on the surface of the frame 1, and is used to transport coal mines;

[0036] The belt pressing and cleaning mechanism 2 is used to press the conveyor belt 101 to prevent the conveyor belt 101 from being lifted up due to the occurrence of folded corners. When the coal is not being transported, it can be converted into a cleaning component to clean the conveyor belt 101. The belt pressing and cleaning mechanism 2 includes two first track frames 201 respectively fixedly connected to the two sides of the frame body 1. The first track frame 201 is internally slidably connected with a slider 202. The end surface of the slider 202 is fixedly connected with a vertical rod 203. The arc surface of the vertical rod 203 is slidably connected with a fixed frame 204. The inner wall of the fixed frame 204 is rotatably connected with a round rod 205. One end of the round rod 205 is fixedly connected with a first motor 206. The output end of the first motor 206 is fixedly connected with a pressing wheel 207. The two pressing wheels 207 are provided with bristles on the sides close to each other.

[0037] In this embodiment, when the fixed frame 204 moves, the slider 202 will slide along the inside of the first track frame 201 to limit the position of the fixed frame 204, and the pressure wheel 207 plays a role in pressing the conveyor belt 101 to prevent the conveyor belt 101 from being bent and lifted up.

[0038] In a further embodiment, referring to Figure 3 and Figure 4 As shown, two adjustment components 208 are used to adjust the position and angle of the pressure wheel 207 so that the pressure wheel 207 can be transformed into a cleaning component. The adjustment component 208 includes a second track frame 2081, a second motor 2082, a screw 2083 and a fixing block 2084;

[0039] The second track frame 2081 is fixedly connected to the side wall of the first track frame 201, the second motor 2082 slides with the inner wall of the second track frame 2081, the screw 2083 is fixedly connected to the output end of the second motor 2082, the fixed block 2084 is threadedly connected to the arc surface of the screw 2083, and the fixed block 2084 is fixedly connected to the side wall of the fixed frame 204.

[0040] In this embodiment, when the screw 2083 rotates, the threaded fixing block 2084 will move, and the front and rear positions of the fixing frame 204, that is, the position of the pressure wheel 207 on the conveyor belt 101, can be adjusted. When the fixing frame 204 slides up and down along the arc surface of the vertical rod 203, the second motor 2082 will slide up and down with the help of the second track frame 2081. The entire adjustment component 208 plays the role of adjusting the pressure wheel 207, so that the pressure wheel 207 can be transformed into a cleaning component to clean the conveyor belt 101.

[0041] In a further embodiment, referring to Figure 3 and Figure 6As shown, the end face of the fixing frame 204 is fixedly connected with a vertical block 209 , and a plug rod 210 is slidably inserted on the surface of the vertical block 209 . The arc surface of the vertical rod 203 is provided with a plurality of plug holes 211 , and the size of the plug rod 210 matches the size of the plug hole 211 .

[0042] In this embodiment, the combination of the insertion rod 210 and the insertion hole 211 plays the effect of stabilizing the position of the fixing frame 204, that is, stabilizing the position of the pressure wheel 207 on the conveyor belt 101.

[0043] In a further embodiment, referring to Figure 3 , Figure 5 and Figure 7 As shown, the protective cleaning mechanism 3 is used to block and protect the debris thrown out by the pressing wheel 207 when the pressing wheel 207 is used as a cleaning component, and can be transformed into a cleaning component to clean the pressing wheel 207 when the pressing wheel 207 presses the conveyor belt 101. The protective cleaning mechanism 3 includes two connecting plates 301 respectively fixedly connected to the two sides of the frame 1, and the surface of the connecting plate 301 is fixedly connected to a spring 302, and the end of the spring 302 away from the connecting plate 301 is fixedly connected to a strip plate 303, and the surface of the strip plate 303 is fixedly connected to a protective plate 306;

[0044] In this embodiment, the cross-sectional shape of the protection plate 306 is an arc shape. When the pressure wheel 207 cleans the conveyor belt 101, the protection plate 306 plays a protective role on both sides, that is, it blocks the broken coal pieces thrown out by the pressure wheel 207 during cleaning.

[0045] Rectangular frames 304 are fixedly connected to both sides of the frame 1 , two strip plates 303 are respectively inserted into the inner walls of the two rectangular frames 304 , and a support column 305 is fixedly connected to the bottom of the rectangular frame 304 , and the bottom of the support column 305 is fixedly connected to the frame 1 .

[0046] In this embodiment, the rectangular frame 304 serves to stabilize the position of the protective plate 306. That is, when the protective plate 306 blocks the broken coal pieces thrown out by the pressure wheel 207, it prevents the spring 302 from being deformed due to the excessive impact force of the broken coal pieces, causing the protective plate 306 to shake. Under the action of the friction between the strip plate 303 and the rectangular frame 304, the stability of the protective plate 306 can be improved.

[0047] One end of the protective plate 306 away from the strip plate 303 is fixedly connected with a block 307, and one end of the protective plate 306 away from the strip plate 303 is provided with a slot 308 adapted to the block 307, the arc surface of the round rod 205 is movably connected with a slide plate 309, the surface of the slide plate 309 is provided with a clamping column 310, and the surface of the strip plate 303 is provided with a clamping hole adapted to the clamping column 310.

[0048] In this embodiment, the slide plate 309 is connected to the round rod 205 in both a sliding and a rotational connection, and the two have their own friction and are not easy to rotate without external force. The two protective plates 306 can be combined together with the help of the blocks 307 and the slots 308 on each other, and with the help of the spring 302, the position of the protective plate 306 can be changed to play the role of cleaning the pressure wheel 207.

[0049] In a further embodiment, referring to Figure 1 , Figure 8 and Fig. 9 As shown, the auxiliary mechanism 4 is used for dust reduction when the coal is piled on the conveyor belt 101. The auxiliary mechanism 4 includes a baffle 401 fixedly connected to the upper part of the frame 1, the inner wall of the baffle 401 is rotatably connected to a cylinder 402, the arc surface of the cylinder 402 is fixedly connected to a first impeller 403 and two second impellers 405, the bottom of the baffle 401 is fixedly connected to two support plates 406, and the end surface of the support plate 406 is provided with a storage frame 407.

[0050] The blades of the first impeller 403 are provided with a plurality of leak holes 404, and the inner wall of the baffle frame 401 is fixedly connected with a cleaning brush 408. The two second impellers 405 are respectively located on both sides of the baffle frame 401, and the two second impellers 405 are respectively located inside the two storage frames 407.

[0051] In this embodiment, the baffle frame 401 is located above the conveyor belt 101, and the storage frame 407 is placed on the support plate 406. The storage frame 407 is filled with water. The leakage hole 404 can reduce the occurrence of the blades of the first impeller 403 being stuck with broken coal blocks, and the cleaning brush 408 serves to clean the broken coal blocks on the first impeller 403.

[0052] The working principle of the present invention is as follows: when in use, the staff dumps the coal into the baffle 401, and the coal will first contact the first impeller 403, and the first impeller 403 will rotate when hit, and drive the second impeller 405 to rotate, and the second impeller 405 will contact the water in the storage frame 407 when rotating, raising water splashes, and the coal enters the baffle 401 and contacts the conveyor belt 101, which will raise dust. The raised water splashes play a role in dust reduction, and the first impeller 403 will contact the cleaning brush 408 during the rotation process, which plays a role in cleaning the first impeller 403;

[0053] Before transporting coal, adjust the position of the protective plate 306. Pull out the strip plate 303 from the rectangular frame 304. With the help of the elastic force of the spring 302, adjust the position of the protective plate 306 at will. Combine the two protective plates 306 together through the card block 307 and the card slot 308 on themselves. Figure 5As shown, at this time, the spring 302 is in a stretched state, and then the slide plate 309 is moved to insert the clamping column 310 on the slide plate 309 into the clamping hole on the strip plate 303 to fix the position of the protective plate 306. At this time, the end of the protective plate 306 is in contact with the pressure wheel 207. When the conveyor belt 101 is transporting coal, the transmission of the conveyor belt 101 will cause the pressure wheel 207 to rotate, so that the broken coal blocks stuck to the pressure wheel 207 during the rotation process will be cleaned up by the protective plate 306, and the pressure of the pressure wheel 207 on the conveyor belt 101 can make the conveyor belt 101 not easy to be picked up;

[0054] When the coal is not being transported, the slide plate 309 is slid to disengage the clamping column 310 from the clamping hole on the strip plate 303. Under the action of the spring 302, the protective plate 306 rebounds, and then the strip plate 303 is reinserted into the rectangular frame 304. At this time, the height of the pressure wheel 207 is first adjusted by sliding the fixed frame 204 and the vertical rod 203, and then the angle of the pressure wheel 207 is adjusted by rotating the round rod 205 and the fixed frame 204, so that the brush surface of the pressure wheel 207 faces the conveyor belt 101, and then the second motor 2082 is started to drive the screw rod 2083 to rotate, and the fixed block 2084 is driven to move. After the fixed frame 204 and the vertical rod 203 are adjusted, the insertion rod 210 can be inserted into the insertion hole 211 to stabilize the pressure wheel 207. Figure 4 As shown, at this time, the first motor 206 is started to drive the pressure wheel 207 to rotate. When the conveyor belt 101 is in transmission, it will contact the brush surface of the pressure wheel 207 to clean the conveyor belt 101.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
