A kind of improved loading shovel

Technical field the utility model relates to a kind of improved loading shovel, requires the higher improved loading shovel of discharge height especially for loading and unloading.

The loader that background technology is present, be mainly used in the handling operation of material, the scraper bowl structure is more single, and the structure of scraper bowl is directly restricting the discharge height of loader, restricting the handling operation efficient of loader, if increase discharge height, generally be the length that simply increases loading arm, consider that simultaneously swing arm increases, center of gravity reach during the scraper bowl loaded material, complete machine stability is bad, so the bucket capacity of loading shovel also will suitably reduce, the handling operation efficient of loader has reduced again like this, for understanding this problem, rationally improve the bucket capacity and the discharge height of loader, thereby goal of the invention of the present utility model has been proposed for the discharge height scope of extended loading machine handling operation and raising loader handling operation efficient.

Summary of the invention goal of the invention of the present utility model is will increase discharge height in order to overcome the loader that exists in the present prior art, generally be the length that simply increases loading arm, consider that simultaneously swing arm increases, center of gravity reach during the scraper bowl loaded material, complete machine stability is bad, so the bucket capacity of loading shovel will suitably reduce, the deficiency that reduced again of the handling operation efficient of loader like this, promptly in order rationally to improve the bucket capacity and the discharge height of loader, thereby the discharge height scope of extended loading machine handling operation and raising loader handling operation efficient, and the technical solution that proposes promptly provides a kind of improved loading shovel.This improved loading shovel, mainly by middle bucket body [1], pull bar bracing frame [2], swing arm medial branch support [3] and swing arm lateral branch support [4], distolateral plate [7], sword plate [8] and both sides bucket body plates [5] and interior plate [9] constitute, this loading shovel is hinged with bearing pin with the receipts tipping bucket pull bar of loader by pull bar bracing frame [2], swing arm medial branch support [3], swing arm lateral branch support [4] are hinged with bearing pin with the swing arm of loader, at the swing arm of loader and receive to shovel under the effect of tipping bucket pull bar and dig handling operation.It is characterized in that respectively having an end bucket body [5] and distolateral plate [7] and the portion of bucket body thereafter of interior plate [9] sealing to protrude from the end bucket [6] of the back bucket body of middle bucket body [1] at the two ends of middle bucket body.The swing arm lateral branch support [4] that cooperates with swing arm medial branch support [3] is fixed on the interior plate [9] of the end bucket [6] that protrudes backward, such structure is owing to increased that part of scraper bowl bucket capacity that protrudes, so can make suitably retraction of sword plate [8] during design, the bucket capacity that sword plate [8] retraction is reduced is replenished by the scraper bowl bucket capacity place that protrudes, thereby center of gravity is moved after also taking place during the scraper bowl loaded material, swing arm also can suitably increase, the discharge height and the whole stability of loader have so just been increased greatly, thereby expanded the discharge height scope of loader handling operation, also can improve the handling operation efficient and the safety of loader.The utility model loading shovel, simple in structure, easily realize.Cost is low, but the discharge height scope of extended loading machine handling operation and raising loader handling operation efficient.

Appended drawings 1 is the vertical view of improved scraper bowl of the present utility model, and accompanying drawing 2 is A-A revolved sectional views of accompanying drawing 1.Vertical view when Fig. 1 is the utility model scraper bowl horizontal positioned, the meaning of component part numbers is in the accompanying drawings: 1, middle bucket body, 2, the pull bar bracing frame, 3, swing arm medial branch support, 4, swing arm lateral branch support, 5, both sides bucket body plate, 6, the end bucket, 7, distolateral plate, 8, the sword plate, 9, interior plate.

Specific embodiment concrete structure embodiment of the present utility model is provided by the embodiment of accompanying drawing.Accompanying drawing is vertical view and the A-A revolved sectional view thereof according to a kind of loading shovel that the utility model proposes.

Describe in detail according to a kind of loading shovel structure and the working condition that the utility model proposes below in conjunction with accompanying drawing.The swing arm of this improved loading shovel and loader and pull bar hinge mounted, mainly by middle bucket body [1], pull bar bracing frame [2], swing arm medial branch support [3] and swing arm lateral branch support [4], distolateral plate [7], interior plate [9], sword plate [8] and both sides bucket body plates [5] are welded, the inner two of its bucket body has the scraper bowl bucket capacity that protrudes, position as [6] in the accompanying drawing 1 can see that the scraper bowl bucket body part that both sides protrude is made of both sides bucket body plates [5], interior plate [9] and distolateral plate [7].The swing arm lateral branch support [4] that cooperates with swing arm medial branch support [3] is fixed on the interior plate [9] of the end bucket [6] that protrudes backward.Swing arm lateral branch support [4] is fixed on the interior plate [9], and the advantage of its protrusion is that swing arm lateral branch support [4] has become the end face fixed support after the improvement by original cantilever support, has improved the rigidity and the stability of its support.Each position of this loading shovel can suitably increase some reinforcing ribs and stiffener as required, also can change the outfit as required on the sword plate [8] to go up the scraper bowl bucket tooth.This improved loading shovel pull bar bracing frame [2] is hinged with bearing pin with the receipts tipping bucket pull bar of loader, swing arm medial branch support [3], swing arm lateral branch support [4] are hinged with bearing pin with the swing arm of loader, at the swing arm of loader and receive to shovel under the effect of tipping bucket pull bar and dig handling operation.The structure that swing arm lateral branch support [4] and interior plate [9] be connected as a single entity of having drawn in the accompanying drawings, if in order to be suitable for the design of trembling of different tonnages, swing arm lateral branch support [4] can be separated with interior plate [9], keep its original installation dimension distance.Perhaps,,, also swing arm lateral branch support [4] directly can be removed, and its endoporus that supports the swing arm bearing pin is directly designed on interior plate [9] for simplified design for the scraper bowl of less tonnage.Above-mentioned these remodeling do not influence application and practice that this is suitable for the major technique feature of the novel scraper bowl structure that protrudes.Can make suitably retraction of sword plate [8] during design, the scraper bowl bucket capacity that the bucket capacity that sword plate [8] retraction is reduced protrudes from both sides is replenished, like this, during the scraper bowl loaded material center of gravity also take place backward, to moving down, therefore, swing arm also can suitably increase, and has so just increased the discharge height of loader greatly, thereby expanded the discharge height scope of loader handling operation, also can improve the handling operation efficient of loader.Since center of gravity backward and move down, also make the resistance to overturning of loader improve, increased the security performance of work production.
