Abstract

The utility model discloses a scraper chain of a scraper conveyor, which includes a chain and a scraper. The scraper is also fixedly provided with a grinding plate which uses non-metallic materials and the chain is a sleeve roller sub-chain or a double-plate chain. The scraper chain is characterized in that: the friction resistance is small; the operation noise is low; the structure is simple and the maintenance is easy. The utility model is widely used in the continuous transportation of materials in plant, and particularly is applicable to grain, chemicals, cement and other industries.

Description

The flight chain of slat conveyer

Affiliated technical field

The utility model relates to a kind of mechanical equipment of continuous conveying, relates in particular to the improvement of flight chain of drag-flight conveyer.

Background technology

Slat conveyer is widely used in factory's bulk cargo, and in the continuous conveying as the grain and oil material of grain and oil industry, it is strong that it has traffic capacity, the characteristics that the convey materials scope is wide.The flight chain of present slat conveyer all adopts captive joint blade structure on conduction chain, because scraper plate and the hopper and the feeding track direct contact of this structure, not only exist friction drag and running noise big, the deficiency that energy consumption is high, and after existing the scraper plate wearing and tearing, chain scraper needs to change in the lump, thereby has strengthened maintenance load, has improved maintenance cost.Especially in the grain and oil industry, flight chain mostly still adopts the casting chain with single carrier bar, when carrying the big or resistance of load inhomogeneous, often causes fractureing of carrier bar, cause whole conveying manufacturing line cisco unity malfunction, be difficult to satisfy the continuous production needs of maximization conveyor line.

Summary of the invention

In order to overcome the deficiency that above-mentioned prior art exists, main purpose of the present utility model is to provide the flight chain of the slat conveyer that a kind of friction drag is little, running noise is low.

Another purpose of the present utility model is that the flight chain of this slat conveyer has characteristics simple in structure, easy to maintenance.

The technical scheme that its technical matters that solves the utility model adopts is: the flight chain of slat conveyer, and comprise chain and be fixed in scraper plate on the chain, also be connected with the antifriction plate on the described scraper plate.

In a preferred embodiment, on scraper plate, the height of this antifriction plate is greater than the height of chain by bolted connection for described antifriction plate.

In another preferred embodiment, described scraper plate is welded on the carrier bar of chain.

After adopting said structure, owing on scraper plate, be fixedly connected with the antifriction plate made from the non-metal antifriction material, push ahead material by the slip of antifriction plate on hopper, not only make scraper plate no longer with the hopper direct contact, and the friction coefficient between antifriction plate and the hopper reduces greatly, thereby alleviated the friction drag that chain bore, reduced power consumption and running noise, improved working environment.Antifriction plate and scraper plate adopt this structure of bolted connection simultaneously, and be simple in structure, and after the wearing and tearing of antifriction plate, it is convenient to change, the service life of having improved equipment.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is flight chain one section the structural front view wherein of the utility model slat conveyer.

Fig. 2 is the birds-eye view of structure shown in Figure 1.

The specific embodiment

Fig. 1, shown in Figure 2 be a segment structure of the flight chain of the utility model slat conveyer, its actual length should be determined according to service condition.Flight chain of the present utility model includes chain 1 and scraper plate 2, chain 1 adopts two plate chains, scraper plate 2 is welded on the carrier bar of chain 1 both sides symmetrically, on the scraper plate 2 of chain 1 both sides, be fixedly connected with antifriction plate 3 by two groups of bolts 4 respectively, this connection mode helps the loading and unloading and the replacing of antifriction plate 3, not only simple in structure, and made things convenient for maintenance.

Antifriction plate 3 adopts the high-density polyethylene material, has so both reduced the friction drag of scraper plate and hopper and base plate, has also reduced running noise.The height H of antifriction plate 3 is greater than the chain plate height of chain 1 and the height h of scraper plate 2, when conveyer was worked, slack-free chain 1 from the hopper base plate, had been avoided the friction of chain 1 with base plate by 3 supports of antifriction plate, further reduce friction drag and running noise, improved conveying effect and mass transport amount.

Scraper plate 2 equidistantly is welded on the both sides carrier bar of chain 1 symmetrically, has guaranteed that feeding is stable, chain is stressed evenly.In case particularly the scraper plate load of certain root flight chain is excessive because at the weld stress concentration, intensity relatively a little less than, this root scraper plate splits off at weld, play a part " safeguard " again, guarantee the unlikely fracture of chain, make still normal operation of whole conveying flow production line.

It below only is preferred implementation of the present utility model.Described chain is not limited to two plate chains, can also adopt chains such as bush roller chaiin or dropforged chain, captive joint mode and the blade structure pattern of scraper plate and carrier bar all can adopt other corresponding usual way or pattern, and vane material also can require to adopt other to have non-metallic material wear-resisting, damping effect according to different process.These modification and improvement all should be considered as belonging to protection domain of the present utility model.
