Abstract
The invention relates to a scraper feeder with an external chain, which consists of a driving device, scrapers, a circular chain, a connecting ring, a sealing chain, a head chain wheel assembly, a tail chain wheel assembly, a rack, a baffle and a wear-resistant bottom plate. And a sealing chain is connected between every two scrapers, and the heights of the sealing chain and the scrapers are consistent. A gap is reserved between the bottom edge of the baffle and the wear-resistant bottom plate, two ends of the scraper extend out of the gap, the sealing chain and the scraper run in the gap, the gap is small, and leakage of materials can be prevented. The material is loaded on the wear-resisting bottom plate, and transmission passes through aircraft nose sprocket assembly drive scraper blade motion, and the scraper blade is pushing away the material through the internal friction power of material and is sliding on the wear-resisting bottom plate to realize the transportation of material, and the bottom plate is not leaked the material, because ring chain, go-between all can not contact the material outside the baffle, greatly reduced wearing and tearing, prolonged life.
Description
Technical Field
The invention relates to a scraper feeder with an external chain, which is mainly used for transshipment feeding and transportation of materials such as coal, rock, ore and the like.
Background
The prior plate feeder has too many rollers, complex structure, insufficient breaking force of a traction chain and no conveying length of a scraper conveyor, gaps exist among chain plates, material leakage is difficult to avoid, and the problems of dead locking of walking wheels, deviation, damage and the like exist. When the scraper conveyor conveys hard rocks or ores, the traction chain runs in conveying materials, abrasion is large, the hard materials are easily extruded between the end of the scraper and the side wall of the groove box to cause scraping and blocking, chain breakage occurs, and chain jumping occurs easily after the materials are brought into a chain nest of the driving chain wheel.
Disclosure of Invention
The invention provides a scraper feeder with an external chain, which aims to solve the problems of the existing plate feeder and scraper conveyor in the feeding process.
The technical scheme adopted by the invention for solving the technical problems is as follows: a scraper feeder with an external chain is composed of a driving device, scrapers, a circular chain, a connecting ring, a sealing chain, a machine head chain wheel assembly, a machine tail chain wheel assembly, a rack, a baffle and a wear-resistant bottom plate. The frame comprises medium plate and a plurality of support post, and wear-resisting bottom plate passes through the bolt fastening on the frame medium plate. The driving device is arranged on one side of the head of the frame, and the tail tensioning device is arranged on one side of the tail of the frame. The scraper, the circular chain and the connecting ring jointly form a scraper chain, and a closed circular chain driving system is formed by the scraper chain, the machine head chain wheel assembly and the machine tail chain wheel which are respectively positioned at the head and the tail of the machine frame and circularly moves under the action of the driving device. And a sealing chain is connected between every two scrapers, and the heights of the sealing chain and the scrapers are consistent. The frame is connected with a wear-resistant bottom plate which is easy to replace, the two side baffles are fixed with the frame, a gap is reserved between the baffles and the wear-resistant bottom plate, the two ends of the scraper extend out of the gap, and the sealing chain and the scraper run in the gap to block leakage of materials. Guide wheels are arranged on the machine head chain wheel assembly and the machine tail chain wheel assembly, the sealing chain is supported and reversed, and the machine tail tension device prevents the circular chain from loosening. The material is loaded on the wear-resisting bottom plate, and transmission passes through aircraft nose sprocket assembly drive scraper blade motion, and the scraper blade is pushing away the material through the internal friction power of material and is sliding on the wear-resisting bottom plate to realize the transportation of material, and the bottom plate is not leaked the material, because ring chain, go-between all can not contact the material outside the baffle, greatly reduced wearing and tearing, prolonged life.
The invention has the beneficial effects that: the circular chain and the connecting ring for traction are not contacted with materials, so that the abrasion is greatly reduced, the service life is prolonged, the material leakage of the bottom plate is avoided, the structure is simple, the failure rate is low, and the falling impact is not afraid.
Description of the drawings:
the invention is further illustrated with reference to the following figures and examples.
FIG. 1 is a sectional view taken along line A-A.
Fig. 2 is a sectional view B-B.
Fig. 3 is a top view of the overall structure with the baffles removed.
In the figure, 1, a frame, 2, a baffle, 3, a scraper, 4, a material, 5, a sealing chain, 6, a connecting ring, 7, a circular chain, 8, a wear-resistant bottom plate, 9, a head chain wheel assembly, 10, a tail chain wheel assembly, 11, a driving device and 12, a tail tensioning device are arranged.
The specific implementation mode is as follows:
in fig. 1, 2 and 3, a scraper feeder with an external chain is composed of a frame 1, a baffle 2, a scraper 3, a sealing chain 5, a connecting ring 6, a circular chain 7, a wear-resistant bottom plate 8, a nose chain wheel assembly 9, a tail chain wheel assembly 10, a driving device 11, and a tail tensioning device 12. The scraper 3, the circular chain 7 and the connecting ring 6 jointly form a scraper chain, and a closed circular chain driving system is formed by the scraper chain, the head chain wheel assembly 9 and the tail chain wheel assembly 10 which are respectively positioned at the head and the tail of the machine frame 1 and circularly moves under the action of the driving device 11. And a sealing chain 5 is connected between every two scraping plates 3, and the heights of the sealing chain 5 and the scraping plates 3 are consistent. The wear-resistant bottom plate 8 which is easy to replace is laid on the rack 1, the two side baffles 2 are fixed with the rack 1, a gap is reserved between the bottom edge of each baffle 2 and the wear-resistant bottom plate 8, two ends of each scraper 3 extend out of the gap, and the sealing chain 5 and the scrapers 3 run in the gap to block leakage of the materials 4. Guide wheels are arranged on the machine head chain wheel assembly 9 and the machine tail chain wheel assembly 13, the sealing chain 5 is supported and reversed, and the machine tail tension device 12 prevents the circular chain 7 from loosening. Material 4 loads on wear-resisting bottom plate 8, and drive arrangement 11 drives scraper blade 3 through aircraft nose sprocket assembly 9 and moves, and scraper blade 3 is pushing away material 4 through the internal friction of material 4 and is sliding on wear-resisting bottom plate 8 to realize the transportation of material 4. The invention has the advantages that the material leakage of the bottom plate is avoided in the using process, the circular chain 7 and the connecting ring 6 are arranged outside the baffle 2 and can not contact the material 4, the abrasion is greatly reduced, the service life is prolonged, the structure is simple, the failure rate is low, and the falling impact is not afraid.
