Abstract
The invention discloses a loader bucket bottom guard board used for a large-tonnage loader bucket, and relates to the technical field of loaders. The loader bucket bottom guard board comprises a bottom plate, a right rib plate, a left rib plate, a rear rib plate and unloading limit blocks, wherein the unloading limit blocks comprise an unloading limit block I, a cushion block and an unloading limit block II; a threaded hole is formed in the unloading limit block I; the unloading limit block I is fixed to the rear rib plate; the unloading limit block II and the cushion block are fixed on the unloading limit block I by a bolt; the cushion block is located between the unloading limit block I and the unloading limit block II; the unloading limit block II is connected with a swing arm hinged plate. The connecting parts of the swing arm hinged plate, the bucket bottom guard board and a bucket wall are prevented from being cracked and deformed, the cushion block between the unloading limit block I and the unloading limit block II is adjusted according to the actual processing condition of the bucket, and the design requirement of the unloading limit angle is met; by using the loader bucket bottom guard board, the bucket wall can be protected, the maintenance of the bucket is facilitated, and the service life of the bucket is thus prolonged.
Description
Technical field
The utility model relates to loader technical field, specifically a kind of for backplate at the bottom of the loading shovel bucket on large-tonnage loading shovel.
Background technology
Backplate at the bottom of the scraper bowl bucket of large-tonnage loader, is mainly made up of base plate, gusset, wearing plate and unloading limited block, and wherein base plate top structure is gusset after two side gussets and, and the structure of unloading limited block be entirety bulk.When loader is in the time shoveling dress, improving material, swing arm hinge hole place load is larger, swing arm articulated slab, bucket end backplate and the easy craze and transfiguration in headwall joint of scraper bowl, and scraper bowl in manufacture process because robot welding and human factor are easy to produce micro-distortion, cause loader in unloading materials process, unload spacing angle and produce deviation, do not reach expected design effect.This structure not only can cause damage to headwall but also shorten application life of scraper bowl.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides backplate at the bottom of a kind of loading shovel bucket.This structure is not only simple and easy to realize but also can extend the application life of scraper bowl.
The technical solution adopted in the utility model is: backplate at the bottom of a kind of loading shovel bucket, and it comprises base plate, right web plate, left gusset, rear gusset and unloading limited block; Described rear gusset is laterally fixed on middle part, base plate one end; Described unloading limited block is fixed on rear gusset, and unloading limited block is connected with swing arm articulated slab; Between described rear gusset and base plate, be arranged symmetrically with right web plate and left gusset; Described right web plate comprises polylith; Described left gusset comprises polylith; Described unloading limited block comprises unloading limited block I, cushion block and unloading limited block II; On described unloading limited block I, have screwed hole and be fixed on rear gusset; It is upper that described unloading limited block II and cushion block are fixed by bolts to unloading limited block I, and cushion block is between unloading limited block I and unloading limited block II, and unloading limited block II is connected with swing arm articulated slab.
It is further: described right web plate comprises right web plate I and right web plate II, and the limit of right web plate I and right web plate II right flank has chamfering; Described left gusset comprises left gusset I and left gusset II, and described left gusset I and the limit of left gusset II left surface have chamfering.
Described unloading limited block I has four screwed holes and is welded on rear gusset.
The utility model has the advantages that: increase left and right gusset and offer chamfering on gusset one side limit the intensity of having strengthened gusset and bucket end backplate, can avoid swing arm articulated slab, bucket end backplate and the headwall joint craze and transfiguration of scraper bowl, and can also be according to the cushion block between scraper bowl actual processing adjustment unloading limited block I and unloading limited block II, to meet the designing requirement at the spacing angle of unloading.At the bottom of this utility model bucket, backplate can protect headwall can facilitate again the maintenance of scraper bowl, and then extends the application life of scraper bowl.
Accompanying drawing explanation
