Abstract

The invention relates to a chain external scraper feeder. Grinding base plate composition. A sealing chain is connected between every two scrapers, and the height of the sealing chain and the scraper is the same. There is a gap between the bottom edge of the baffle plate and the wear-resistant bottom plate, and both ends of the scraper protrude from this gap. The sealing chain and the scraper run in this gap, and the gap is small, which can prevent the leakage of materials. The material is loaded on the wear-resistant bottom plate, and the transmission device drives the scraper to move through the machine head sprocket assembly. The scraper pushes the material to slide on the wear-resistant bottom plate through the internal friction of the material, so as to realize the transportation of the material, and the bottom plate does not leak. , Since the ring chain and the connecting ring are outside the baffle and cannot touch the material, the wear is greatly reduced and the service life is prolonged.

Description

A chain external scraper feeder

technical field

The invention relates to a chain external scraper feeder, which is mainly used for the transfer and feeding transportation of coal, rock, ores and other materials.

Background technique

The current apron feeder has too many rollers, complex structure, insufficient breaking force of the traction chain, and cannot achieve the transport length of the scraper conveyor, and there are gaps between the chain plates, which is difficult to avoid material leakage, and there are also walking wheel jams. Death, deviation, damage, etc. When the scraper conveyor is transporting hard rocks or ore, the traction chain runs in the conveying material, and the wear is large, and the end of the scraper and the side wall of the tank are easy to squeeze into the hard material, causing the scraping card, chain breakage, material After being brought into the chain pocket of the drive sprocket, the phenomenon of chain skipping is easy to occur.

SUMMARY OF THE INVENTION

In order to solve the problems existing in the feeding process of the existing plate feeders and scraper conveyors, the present invention provides an external chain scraper feeder.

The solution adopted by the present invention to solve the technical problem is: an external chain scraper feeder, which consists of a driving device, a scraper, a circular chain, a connecting ring, a sealing chain, a head sprocket assembly, and a tail sprocket Components, frame, baffle, wear-resistant bottom plate. The frame is composed of a middle plate and several supporting columns, and the wear-resistant bottom plate is fixed on the middle plate of the frame by bolts. The driving device is installed on one side of the head of the frame, and the tail tensioning device is installed on one side of the tail of the frame. The scraper, the ring chain and the connecting ring together form the scraper chain, which together with the head sprocket assembly and the tail sprocket located at the head and tail of the frame respectively form a closed ring chain drive system, under the action of the driving device circular motion. A sealing chain is connected between every two scrapers, and the height of the sealing chain and the scraper is the same. The frame is connected to the wear-resistant bottom plate which is easy to replace. The two side baffles are fixed with the frame. There is a gap between the baffle plate and the wear-resistant bottom plate. Both ends of the scraper protrude from this gap. It runs in this gap to block the leakage of materials. The nose sprocket assembly and the tail sprocket assembly are provided with guide wheels to support and reverse the sealing chain, and the tail tensioning device prevents the ring chain from loosening. The material is loaded on the wear-resistant bottom plate, and the transmission device drives the scraper to move through the machine head sprocket assembly. The scraper pushes the material to slide on the wear-resistant bottom plate through the internal friction of the material, so as to realize the transportation of the material, and the bottom plate does not leak. , Since the ring chain and the connecting ring are outside the baffle and cannot touch the material, the wear is greatly reduced and the service life is prolonged.

The beneficial effects of the invention are: the circular chain and the connecting ring used for traction are not in contact with the material, which greatly reduces the wear and improves the service life;

Detailed ways:

In Figure 1, Figure 2 and Figure 3, a chain external scraper feeder consists of 1. frame, 2. baffle, 3. scraper, 5. sealing chain, 6. connecting ring, 7. Ring chain, 8. Wear-resistant bottom plate, 9. Machine head sprocket assembly, 10. Machine tail sprocket assembly, 11. Drive device, 12. Machine tail tensioning device. The scraper 3, the ring chain 7 and the connecting ring 6 together form a scraper chain, and the head sprocket assembly 9 and the tail sprocket assembly 10 located at the head and tail of the frame 1 respectively form a closed ring chain drive system , cyclically moves under the action of the driving device 11 . A sealing chain 5 is connected between every two scrapers 3 , and the height of the sealing chain 5 and the scraper 3 is the same. An easily replaceable wear-resistant bottom plate 8 is laid on the frame 1. The two side baffles 2 are fixed with the frame 1. There is a gap between the bottom edge of the baffle 2 and the wear-resistant bottom plate 8. The gap protrudes, and the sealing chain 5 and the scraper 3 run in this gap to block the leakage of the material 4 . The nose sprocket assembly 9 and the tail sprocket assembly 13 are provided with guide wheels to support and reverse the sealing chain 5, and the tail tensioning device 12 prevents the ring chain 7 from loosening. The material 4 is loaded on the wear-resistant bottom plate 8, the driving device 11 drives the scraper 3 to move through the machine head sprocket assembly 9, and the scraper 3 pushes the material 4 to slide on the wear-resistant bottom plate 8 through the internal friction force of the material 4, so as to realize Transportation of material 4. In the present invention, the bottom plate does not leak material during the use process. Since the circular chain 7 and the connecting ring 6 are not in contact with the material 4 outside the baffle plate 2, the wear and tear are greatly reduced, the service life is prolonged, the structure is simple, the failure rate is low, and it is not afraid of falling. material impact.
