Description

Technical Field

[0001] The invention relates to the technical field of conveyor belts, in particular to a smash-resistant buffer conveyor belt. Background Art

[0002] Conveyor belts are suitable for transporting powdered and block materials between various processes and sections. They have high production efficiency and are a necessary means for continuous transportation of materials in modern large-scale production. Existing conveyor belts are composed of an upper covering layer, a skeleton layer, a lower covering layer and side rubber layers on both sides of the skeleton layer. The upper covering layer and the lower covering layer are made of rubber. The skeleton layer of the belt is the strong layer of the belt, which bears the main pulling force during the operation of the belt. The upper and lower covering rubbers play a role in protecting the skeleton layer. In the processes of stone mining, cement plant ore feed inlet, limonite screening, etc., due to the high material density, sharp shape, large conveying volume, high linear speed, large drop and other reasons, higher requirements are placed on the conveyor belt.

[0003] The existing conveyor belt is frequently impacted during use, causing the buffer layer to gradually lose its elasticity, resulting in serious local wear of the conveyor belt, which requires local repair, increasing labor and material costs. The existing buffer conveyor plate reduces the impact force by adding anti-dust scrapers, but this method causes the overall operation of the conveyor belt to be unstable, which is easy to cause local stress concentration and cause failure. To this end, we propose a smash-resistant buffer conveyor belt. Summary of the invention

The conveyor mechanism 1 includes a material retaining frame 101. Both the front and rear ends inside the material retaining frame 101 are rotatably connected with driving rollers 102. A conveyor belt 103 is engaged inside the material retaining frame 101 between the driving rollers 102. The setting of the driving rollers 102 facilitates the smooth operation of the conveyor belt 103. Both the front and rear ends of the bottom of the material retaining frame 101 are provided with load-bearing frames connected to an external fixing mechanism, and the load-bearing frames play a load-bearing role for the material retaining frame 101. The side wall of the conveyor belt 103 contacts the inner wall of the material retaining frame 101, and anti-slip blocks are provided on both the inner wall of the conveyor belt 103 and the outer wall of the driving roller 102. The setting of the anti-slip blocks effectively prevents the conveyor belt 103 from slipping. The material retaining frame 101 is divided into left and right parts. The setting of the material retaining frame 101 facilitates the replacement of the conveyor belt 103, and the material retaining frame 101 plays a guiding role for the conveyor belt 103.

[0027] The inner wall of the material baffle 101 is connected to the fixing bolt 105 through the bolt tube 104. The bolt tube 104 is fixedly connected to the inner wall of the material baffle 101 on the left side of the conveyor belt 103. A fixing hole meshing with the fixing bolt 105 is provided on the side wall of the material baffle 101 on the right side of the conveyor belt 103. Threads meshing with the outer wall of the fixing bolt 105 are provided on the inner wall of the bolt tube 104.

Both ends of the belt adjusting roller 106 are slidably connected to the adjusting grooves through the rotating rods provided. The setting of the adjusting grooves facilitates the adjustment of the position of the belt adjusting roller 106.

[0028] Fixing blocks 107 are sleeved on both ends of the belt adjusting roller 106 located outside the material baffle 101. A buffer spring 108 is fixedly connected to the bottom end of the fixing block 107. The setting of the buffer spring 108 forms an elastic connection between the belt adjusting roller 106 and the conveyor belt 103. A buffer hydraulic rod 109 is fixedly connected to the bottom end of the buffer spring 108. The bottom wall of the material baffle 101 is connected to the buffer hydraulic rod 109 through a fixing bracket. The buffer hydraulic rod 109 is composed of an electric hydraulic rod. A tension detection module 110 is fixedly connected between the buffer hydraulic rods 109. The tension detection module 110 is driven by an external power device. The tension detection module 110 plays a role in real-time monitoring of the force exerted by the conveyor belt 103 on the buffer spring 108.

[0029] The left end of the driving roller 102 at the rear end of the material baffle 101 is connected to an external motor through a gear. The external motor drives the conveyor belt 103 to run through the driving roller 102 at the rear end of the material baffle 101. The buffer hydraulic rod 109 adjusts the buffer spring 108 through the tension detection module 110. The buffer spring 108 drives the belt adjusting roller 106 to move through the fixing block 107, thereby realizing the tension adjustment of the conveyor belt 103. A cleaning roller 4 is provided inside the rear end of the material baffle 101 near the outer wall of the driving roller 102. The left end of the cleaning roller 4 is connected to an external motor.

[0030] The feeding mechanism 2 is arranged at the top of the rear end of the material baffle 101. The feeding mechanism 2 includes a feeding bin 201. A discharge port is provided at the bottom of the front end of the feeding bin 201. The feeding bin 201 is fixedly connected to the top of the rear end of the material baffle 101. A blanking wheel 202 is rotatably connected to the top end inside the feeding bin 201. The setting of the blanking wheel 202 facilitates intermittent blanking of stones. Semi-circular grooves are provided at both the upper and lower ends inside the blanking wheel 202. The setting of the semi-circular grooves facilitates the limiting of stones. A rotating wheel 203 is fixedly connected to the right end of the blanking wheel 202 outside the feeding bin 201. A driving wheel 204 is engaged with the rear end of the rotating wheel 203. A servo motor 205 is fixedly connected to the right end of the driving wheel 204. The top wall of the servo motor 205 is connected to the side wall of the feeding bin 201 through a set bracket. The buffer mechanism 3 is arranged inside the feeding mechanism 2. The buffer mechanism 3 includes a rotating shaft 301. The right side wall of the feeding bin 201 is rotatably connected to the rotating shaft 301 through a set connecting block 206. The connecting block 206 fixes the rotating shaft 301. A connecting frame 302 is fixedly connected between the side wall of the connecting block 206 and the side wall of the material baffle 101. The connecting frame 302 supports the buffer mechanism 3. Blocking plates 303 are fixedly connected to both the upper and lower sides of the outer wall of the rotating shaft 301. The blocking plates 303 are arranged in a 180-degree fan shape. There is an angle between the blocking plates 303 arranged at the upper and lower ends of the rotating shaft 301. The angular arrangement of the blocking plates 303 prevents the stones from directly falling above the conveyor belt 103 from the blocking plate 303 at the top of the rotating shaft 301.

[0031] The bottom wall of the material blocking plate 303 at the bottom of the rotating shaft 301 and the outer wall of the conveyor belt 103 are slidably connected. The bottom end of the rotating shaft 301 is fixedly connected with a worm gear 304. A worm 305 is engaged with the right side of the worm gear 304. Both ends of the worm 305 are rotatably connected to the side wall of the material blocking frame 101 by arranging limit blocks. The rear end of the worm 305 is fixedly connected with a driving motor 306. The driving motor 306 is connected to the side wall of the material blocking frame 101. A rotating groove 207 engaged with the material blocking plate 303 is provided inside the feed bin 201 and on the right side wall of the material blocking frame 101. The rotating groove 207 plays a role in supporting and guiding the material blocking plate 303. Dust scrapers 208 are fixedly connected to the outer wall of the feed bin 201 and the side wall of the material blocking frame 101 near the rotating groove 207. The dust scrapers 208 clean the stones adhered to the top of the material blocking plate 303. The stones enter the feeding mechanism 2 from the feed bin 201. The servo motor 205 drives the driving wheel 204 to intermittently rotate for two weeks. The driving wheel 204 drives the rotating wheel 203 to rotate 180 degrees. The rotating wheel 203 drives the blanking wheel 202 to perform quantitative blanking of the stones. The stones entering the feed bin 201 fall on the material blocking plate 303 at the top of the rotating shaft 301. The driving motor 306 drives the worm gear 304 to rotate through the worm 305. The worm gear 304 drives the material blocking plate 303 to rotate through the rotating shaft 301. When the material blocking plate 303 at the top of the rotating shaft 301 moves out of the feed bin 201, the stones fall on the material blocking plate 303 at the bottom of the rotating shaft 301. The rotating shaft 301 continuously drives the material blocking plate 303 to rotate. The material blocking plate 303 at the bottom of the rotating shaft 301 drives the stones to enter the conveyor belt 103 under the action of the material blocking frame 101. At the same time, the material blocking plate 303 at the top of the rotating shaft 301 limits the feed bin 201 again. The cleaning roller 4 removes the dust on the surface of the conveyor belt 103 under the action of an external motor.

[0032] Working principle: When the impact-resistant and buffer conveyor belt is in use, an external motor drives the conveyor belt 103 to run through the driving roller 102 at the rear end of the material baffle 101. The buffer hydraulic rod 109 adjusts the buffer spring 108 through the tension detection module 110. The buffer spring 108 drives the belt adjusting roller 106 to move through the fixing block 107, so as to realize the tension adjustment of the conveyor belt 103. The stone enters the feeding mechanism 2 from the feeding bin 201. The servo motor 205 drives the driving wheel 204 to rotate intermittently for two weeks. The driving wheel 204 drives the rotating wheel 203 to rotate 180 degrees. The rotating wheel 203 drives the blanking wheel 202 to carry out quantitative blanking of the stone. The stone entering the feeding bin 201 falls on the material blocking plate 303 at the top of the rotating shaft 301. The driving motor 306 drives the worm gear 304 to rotate through the worm 305. The worm gear 304 drives the material blocking plate 303 to rotate through the rotating shaft 301. When the material blocking plate 303 at the top of the rotating shaft 301 moves out of the feeding bin 201, the stone falls on the material blocking plate 303 at the bottom of the rotating shaft 301. The rotating shaft 301 continuously drives the material blocking plate 303 to rotate. The material blocking plate 303 at the bottom of the rotating shaft 301 drives the stone to enter the conveyor belt 103 under the action of the material baffle 101. At the same time, the material blocking plate 303 at the top of the rotating shaft 301 limits the feeding bin 201 again. The cleaning roller 4 removes the dust on the surface of the conveyor belt 103 under the action of the external motor.
