Description

Technical Field

[0001] This utility model relates to the technical field of anti-clogging limestone raw material conveying devices, specifically an anti-clogging limestone raw material conveying device. Background Technology

[0002] The raw materials used to produce quicklime are mainly carbonate rocks, with CaCO3 as the main element, which is what we usually call limestone. There are many types of limestone, the most common of which are: granular crystalline limestone, dense limestone, porous limestone, earthy limestone, marl limestone, chalk, dolomite, and shell-calcareous river pebbles, etc.

[0003] In existing limestone raw material transportation methods, after the mined limestone ore is transported by truck and dumped into a silo, it is then conveyed to a jaw crusher for crushing via a vibrating feeder. However, during the transportation process, the transport of a large number of large rocks into the jaw crusher may cause blockages, requiring manual handling. Manually crushing large rocks in the jaw crusher poses safety hazards. Therefore, we have proposed an anti-blockage limestone raw material transportation device to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide an anti-clogging limestone raw material conveying device to solve the problem mentioned in the background art where a large number of large stones are conveyed into the jaw crusher and damaged, causing the crusher to become clogged.

[0022] Please see Figure 1-5 This utility model provides a technical solution: an anti-clogging limestone raw material conveying device, including a base 1, a hopper 2, and a vibrating feeder 3;

[0023] The base 1 has a hopper 2 at its top, and a vibrating feeder 3 is located at the discharge port below the hopper 2. The vibrating feeder 3 contains a material distribution component 4. The base 1 also has a first feeder 5 and a second feeder 6 at its top. The second feeder 6 contains a feeding belt 12 with sieve holes on its surface. Guide plates 13 are located on both sides of the bottom of the second feeder 6, and both sets of guide plates 13 are inclined towards the center. The four bottom corners of the second feeder 6 are connected to the base 1 via a vibration component 7. The vibration component 7 includes a support plate 701, a rotating shaft 702, and a cam 703. The second feeder 6 has rollers 704, push rods 705, and first springs 706. Support plates 701 are provided at the four corners of the second feeder 6. Rotating shafts 702 are rotatably provided in each of the four sets of support plates 701. Cams 703 are installed on the rotating shafts 702. Push rods 705 are slidably provided through the top of each of the four sets of support plates 701. First springs 706 are sleeved on the push rods 705. One end of the first spring 706 is connected to the inside of the support plate 701. Rollers 704 are provided at the lower end of the push rods 705. The rollers 704 and cams 703 are in surface contact. Motors that drive the rotating shafts 702 are provided on each of the four sets of support plates 701.

[0024] The material distribution assembly 4 includes a shock absorber 401, an assembly plate 402, a moving block 403, a fixing component 404, a guide rod 405, a fixing plate 406, and a sleeve 407. The vibrating feeder 3 has three sets of assembly plates 402, each with multiple sets of limiting holes 8. Limiting rods 9 slide through the three sets of moving blocks 403, and these limiting rods 9 are adapted to the limiting holes 8. The three sets of assembly plates 402 are connected to the vibrating feeder 3 via three sets of shock absorbers 401. The vibrating feeder 3 is equipped with a shock-absorbing spring 10 and a connecting rod 11 that slides inside the shock-absorbing cylinder 401. One end of the shock-absorbing spring 10 is connected to the bottom end of the connecting rod 11, and the top end of the connecting rod 11 is connected to the bottom end of the assembly plate 402. Three sets of detachable moving blocks 403 are slidably provided inside the assembly plates 402. Three sets of guide rods 405 are provided inside the vibrating feeder 3. Fixing members 404 for fixing the guide rods 405 are hinged on both sides of the moving blocks 403. The two sets of fixing members 404 are connected by double-headed bolts.

[0025] Working principle: When using the anti-clogging limestone raw material conveying device, the raw material in the hopper 2 enters the vibrating feeder 3 below and is conveyed by the vibrating feeder 3. At the same time, multiple sets of guide rods 405 inside the vibrating feeder 3 screen the stones. At this time, larger stones are on the surface of the guide rods 405, and smaller stones enter the vibrating feeder 3 for conveying. After the stone falls above the guide rod 405, the stone and the guide rod 405 collide. At this time, the mounting plate 402 drives the connecting rod 11 below to slide inside the shock absorber 401. At the same time, the shock absorber spring 10 inside the shock absorber 401 contracts. Since the internal space of the shock absorber 401 is sealed, the internal shock absorber spring 10 contracts during the movement of the connecting rod 11, and the air in the shock absorber 401 is compressed, thus buffering the guide rod 405 and reducing the impact force. At the same time, the distance between the guide rods 405 can be adjusted according to the size of the stone. When adjusting, after pulling out the limiting rod 9 on the mounting plate 402, the moving block 403 is pulled to slide inside the mounting plate 402 to adjust the distance between the guide rods 405. After the adjustment is completed, the moving block 403 is fixed by the limiting rod 9 and the limiting hole 8. When the guide rod 405 needs to be disassembled, the fixing parts 404 on both sides of the guide rod 405 are separated using double-headed bolts. After the fixing parts 404 are unfolded by the hinge shaft, the guide rod 405 can be removed and replaced. At this time, the vibrating feeder 3 transports smaller stones to the feeding belt 12 inside the second feeder 6 for conveying. Meanwhile, larger stones, which are above the guide rod 405, are transported to the first feeder 5. The first feeder 5 transports the large stones to the external crusher for pre-crushing before entering the jaw crusher. This avoids blockage of the jaw crusher due to too many large stones entering. Since a lot of soil will remain on the surface of the stones, excessive soil... This will affect subsequent limestone production. At this point, the motor can drive the rotating shaft 702 to rotate, which in turn drives the cam 703 to rotate. The protrusions on the surface of the cam 703 drive the roller 704 to move, causing the roller 704 to push the push rod 705. Simultaneously, the first spring 706 on the surface of the push rod 705 contracts. The push rod 705 then drives the upper second feeder 6 to move. The continuous rotation of the cam 703 drives the second feeder 6 to repeatedly vibrate up and down, shaking the stones and soil on the surface of the upper feed belt 12. The soil is then screened out through the surface sieve holes and conveyed to the center through the guide plates 13 on both sides of the bottom for subsequent processing. The stones after soil screening enter the jaw crusher for crushing, thus completing a series of processes.
