Technical Field

[0001] The utility model relates to the technical field of quarrying equipment, in particular to a belt conveyor used in a quarry. Background Art

[0002] At present, most of my country's small and medium-sized quarries are hillside quarries with an annual production scale of 30,000 to 50,000 tons. The mining range is generally less than 0.01KM2, and the maximum mining height of the quarry is generally 20 to 50 meters. Due to the small mining boundary permitted by the mining rights and the steep original slope of the quarry terrain, it is necessary to use transmission to reduce the difficulty of mining and transportation.

[0003] A Chinese patent application CN201320473303.6 discloses a belt conveyor, and the key points of its technical solution are: the belt conveyor provided by the utility model has the following advantages compared with the prior art: first, since it includes a power mechanism, a speed reduction mechanism, a roller, a conveyor belt, rollers and a frame, the roller includes a roller shaft and a roller shell connected to the roller shaft through a bearing, the roller shell includes a blocking surface at both ends and a roller body side surface, the side surface of the roller shell is a curved surface obtained by rotating a circle around the straight line where the roller shaft is located, and the roller shaft is fixed on the frame, so that , which not only ensures that the cross-section of the conveyor belt is low in the middle and high on both sides to prevent materials from falling off, but also increases the diameter of the roller shaft, thereby improving the overall strength of the roller, reducing the number of rotations of the bearing, extending the service life of the bearing, increasing the material transportation volume, and improving work efficiency. In addition, there are no edges and corners on the surface of the roller, which reduces the wear on the belt and extends the life of the belt. Secondly, since the curve is a hyperbola or a parabola, it is not only easy to process, but also the force is evenly applied at each point, further extending its service life. Thirdly, since buffer grooves along the direction of the roller shaft are arranged at intervals on the side surfaces of the roller body of the roller shell, they play a buffering role when the material falls on the conveyor belt.

The rotating driving rod 9 rotates in the connecting plate 8, the driving rod 9 drives the blocking plate 4 to move, the blocking plate 4 drives the long plate 12 to move, and the long plate 12 drives the rubber rod 13 to move, so that the staff can level the broken stones piled to a certain height and prevent the broken stones in the conveying from falling from the surface of the conveyor belt 2. A slide plate 11 is slidably inserted in the connecting plate 8, and one side of the slide plate 11 is fixedly connected to the blocking plate 4. The rotating driving rod 9 rotates in the connecting plate 8, the driving rod 9 drives the rotating plate to move, and the blocking plate 4 drives the sliding rod to slide in the connecting plate 8, so that the blocking plate 4 is prevented from rotating with the rotation of the driving rod 9, thereby improving the stability of the device. A semicircular plate 14 is fixedly connected to the surface of the blocking plate 4, and a plug plate 15 is slidably inserted in the semicircular plate 14. A limiting groove is provided on the surface of the long plate 12, and a mounting plate 16 is fixedly connected to one side of the semicircular plate 14. Push the long plate 12 to slide on the inner surface of the sliding hole of the blocking plate 4, push the mounting plate 16 to drive the plugging plate 15 to slide in the semicircular plate 14 until the plugging plate 15 is inserted into the limiting groove of the long plate 12, so that the staff can perform regular replacement and maintenance operations on the rubber rod 13. The side of the mounting plate 16 close to the semicircular plate 14 is fixedly connected with a spring 17, and one end of the spring 17 is fixedly connected to the side of the semicircular plate 14 close to the mounting plate 16. Push the long plate 12 to slide in the sliding hole of the blocking plate 4, the long plate 12 is squeezed with the plugging rod, and the plugging rod slides in the semicircular plate 14. At this time, the spring 17 is in a stretched state until the plugging rod is aligned with the limiting groove of the long plate 12. The elastic force of the spring 17 drives the plugging rod to automatically insert into the limiting groove of the long plate 12, thereby improving the quickness of the device. The surface of the blocking plate 4 is fixedly connected with two fixing frames 18, and the size of the plugging plate 15 is adapted to the size of the limiting groove of the long plate 12. The blocking plate 4 drives the height frame to move, preventing the broken stones from coming off the edge after contacting the rubber rod 13. The end of the driving rod 9 away from the blocking plate 4 is fixedly connected with a handle 19. The handle 19 is turned to drive the driving rod 9 to rotate in the connecting plate 8, so that the staff can quickly turn the driving rod 9 to adjust the position of the rubber rod 13.

[0028] Working principle: when the staff needs to transport the crushed stones, they pull the elliptical plate 6 to drive the round rod 5 to slide in the sliding hole of the fixed bin 3, and the round rod 5 drives the baffle plate 4 to slide in the fixed bin 3, and the screw rod 7 is rotated to rotate in the elliptical plate 6 until the screw rod 7 abuts against the fixed bin 3. When the position of the rubber rod 13 and the conveyor belt 2 needs to be adjusted, the driving rod 9 is rotated to rotate in the connecting plate 8, and the driving rod 9 drives the blocking plate 4 to move, and the blocking plate 4 drives the long plate 12 to move, and the long plate 12 drives the rubber rod 13 to move, so that the staff can level the crushed stones accumulated to a certain height to prevent the crushed stones in transportation from falling from the surface of the conveyor belt 2, and the driving rod 9 is rotated to rotate in the connecting plate 8, and the driving rod 9 drives the rotating plate to move, and the blocking plate 4 drives the sliding rod to slide in the connecting plate 8, so as to avoid the blocking plate 4 rotating with the rotation of the driving rod 9, and push the long plate 12 to slide on the inner surface of the sliding hole of the blocking plate 4. The movable mounting plate 16 drives the plug plate 15 to slide in the semicircular plate 14 until the plug plate 15 is inserted into the limiting groove of the long plate 12, so that the staff can perform regular replacement and maintenance operations on the rubber rod 13, and push the long plate 12 to slide in the sliding hole of the blocking plate 4, the long plate 12 is squeezed by the plug rod, and the plug rod slides in the semicircular plate 14. At this time, the spring 17 is in a stretched state. Until the plug rod is aligned with the limiting groove of the long plate 12, the elastic force of the spring 17 drives the plug rod to automatically insert into the limiting groove of the long plate 12, thereby achieving the effect of blocking the gravel on the surface of the conveyor belt 2, avoiding the staff from placing gravel on the surface of the conveyor belt 2. Because it is necessary to continuously place gravel of different sizes on the surface of the conveyor belt 2 to maintain the workload, the gravel will accumulate to a certain height on the surface of the conveyor belt 2, resulting in the gravel falling from the surface of the conveyor belt 2 to the ground, reducing the working efficiency of the conveyor belt 2 and improving the practicability of the device.
