Four side plates 120 are connected.
In the present embodiment, the bucket body 1 includes evading portion, when the chain 4 pulls up the bucket body 1
When, it is described to evade between portion and the drawing article provided with gap 5, directly it is in contact so as to avoid chain 4 with bucket body 1,
Enter without producing friction between bucket body 1, therefore abrasion will not be caused to bucket body 1.
In the present embodiment, the portion of evading is located at the left side of trunnion base 2, equally, the side of auris dextra axle bed 3
Evade portion provided with one, in the present embodiment, second side plate 111 is evades portion, because of the second side plate 111 and the first side plate 110
Between be formed with obtuse angle, when chain 4 is connected with left trunnion base 2 and pulls bucket body 1, when chain 4 is pullled backward, chain
Bar 4 and evading is not directly contacted between portion, gap 5 is formed with, so as to avoid the friction with bucket body 1.
In addition, because, right plate 12 is set with left plate 11 for mirror image, therefore, the 4th side plate 120 is also to evade portion, because
Obtuse angle is formed between 4th side plate 120 and the 3rd side plate 121, when chain 4 is connected with auris dextra axle bed 3 and pulls bucket body
When 1, when chain 4 is pullled backward, chain 4 and evading is not directly contacted between portion, gap 5 is formed with, so as to avoid and dig
Friction between bucket body 1.
In the present embodiment, it is described evade include and second point in portion at first point, described first point and the second point are set
In on the same surface for evading portion, first point evaded in portion to the chain 4 when pulled where vertical plane
First vertical range aa and the second point evaded in portion to the chain 4 when pulled where vertical plane second it is vertical away from
Different from bb, the portion of evading includes outer surface, wherein, the outer surface for evading portion in inclined-plane or cambered surface or other do not advise
Then picture surface, in the present embodiment, the portion of evading is in inclined-plane.
In the present embodiment, the bucket body 1 is provided with back timber, and the back timber upper end is provided with the first hole for hoist, the top
It is all public for those skilled in the art that beam lower end is provided with back timber, the first hole for hoist and the second hole for hoist in the second hole for hoist, this programme
The part known, therefore indicate not in the drawings.
In another embodiment, using bucket body 1 by direction during 4 pull-up of chain to be upper, the upper end of second side plate 111
Portion is evaded in setting, and the upper end of the 4th side plate 120 is also equipped with the portion of evading, wherein, the portion of evading includes medial surface and outer
Sideways, described first point and the second point be all located at it is described evade on the medial surface in portion, or described first point and described the
2 points be all located at it is described evade on the lateral surface in portion, when chain 4 pulls bucket body 1, chain 4 passes through the He of the second side plate 111
During the upper end of the 4th side plate 120, it is not directly contacted between the portion of evading, gap 5 has been remained between the two, so that chain 4
Avoid rubbing between bucket body 1.
Before the bucket body 1 is used, left trunnion base 2 is connected with chain 4, and auris dextra axle bed 3 is connected with chain 4,
Chain 4 is connected with bucket crane, the part that bucket crane is known to the skilled person in this programme, therefore marks not in the drawings
Show, bucket crane pulls left trunnion base 2 and auris dextra axle bed 3 after pulling up chain 4, the stress of chain 4, because of left trunnion base 2 and left side
Plate 11 is connected, and auris dextra axle bed 3 is connected with right plate 12, therefore chain 4 can pull up bucket body 1, also, left plate 11
The second side plate 111 and the first side plate 110 between the first included angle A be obtuse angle, therefore, chain 4 pull bucket body 1 when, energy
It is enough to maintain gap 5 the second side plate 111 between, it is to avoid to be directly in contact with the second side plate 111 and cause friction, equally, the right side
The 3rd angle C between 4th side plate 120 of side plate 12 and the 3rd side plate 121 is obtuse angle, therefore, chain 4 can be with the 4th side plate
Gap 5 is maintained between 120, it is to avoid be directly in contact with the 4th side plate 120 and to cause friction.
The brilliant of the present invention is without the mining large-scale traction bucket of strut, by being provided on bucket body 1 by bucket
The connecting portion that body 1 is connected with drawing article, in addition, bucket body 1 includes the portion of evading, this evade portion and the drawing article it
Between gap 5 is set, so, when drawing article pulls bucket body 1 by connecting portion, because drawing article and evading is provided between portion
Gap 5, and then drawing article will not touch bucket body 1, enter without because producing friction between bucket body 1, enter without
Strut is set between drawing article to prevent drawing article and bucket body 1 from producing friction, it is of the invention because eliminating spacer member,
And then production cost and maintenance cost are saved, and because having lacked spacer member, and mitigate bucket overall weight, save
Energy expenditure in work.
