Abstract

The utility model relates to a novel lengthened bucket handle for the digger. The rear low cover plate is welded with the front low cover plate. The front, middle and rear side plates are welded each other to the two side walls of the front and rear low cover plate. The front, middle and rear upper plates are welded each other with the front, middle, rear side plate at the two side walls, so the hollow bucket handle is formed. An enforced rib plate is welded in the bucket handle, ends of the plate are fixed to be linked to the front end of the bucket handle; the front low cover plate is provided with a box enforcement element in order to enforce locally and prolong the operation life; the arc section is cancelled and the stress concentration area is eliminated, the safe operation performance is improved; the prolonged operation part can meet the application requirement of the iterative and variable load in the strip mine. The utility model is applied to be equipped with the shovel of WK10 electrical digger for ore loading operation.

Description

The novel lengthened dipper of excavator

Technical field

The utility model belongs to the excavator field of components, relates to a kind of novel lengthened dipper of excavator.

Background technology

Existing excavator boom, be to be welded into hollow box body by lower cover, side plate, upper plate, normally lower cover and front side board change section part are designed to arc nest shape, when welding, this structure is difficult to coincide mutually, making arc nest deformation section transitional region that stress very easily take place concentrates and ftractures, there is hidden danger, influences application life; And existing excavator boom is because limited length, and its digging radius, unloading radius, discharge height can not satisfy the opencut instructions for use of changeable load repeatedly.

Summary of the invention

It is a kind of safe and convenient to use that the purpose of this utility model is to provide, and increases the service life the novel lengthened dipper of the excavator that has wide range of applications.

The technical solution adopted in the utility model: the novel lengthened dipper of a kind of excavator, comprise lower cover, termination, side plate, upper plate, thereafter lower cover and preceding lower cover welding, before, during and after side plate be welded to each other and with the welding of the two sides of front and back lower cover, before, during and after upper plate be welded to each other and be welded on two sides before, during and after above the side plate, constitute hollow dipper thus, be welded with the reinforcement gusset in the dipper, the termination connects firmly at the dipper front end; The lower cover bottom surface is provided with a box-shaped intensive aspect before described.

Described box-shaped intensive aspect front portion is the inclined-plane, and the rear portion is a cambered surface.

The working portion lengthening 0.85-1.5 rice of described dipper postmedian.

The positive beneficial effect that the utility model had:

1. cancel arc nest deformation section, eliminated area of stress concentration, improved safe application performance;

2. a box-shaped intensive aspect is set up in preceding lower cover bottom surface, carry out local stiffening, gain in strength, increase the service life;

3. Background Job has partly been extended 1.5 meters, can satisfy the opencut instructions for use of changeable load repeatedly, had wide range of applications;

4. reasonable in design, increase work efficiency 30%, be applicable to the spader of WK10 electric excavator supportingly, load the ore operation.

Description of drawings

Fig. 2 is the vertical view of the utility model structural representation;

Fig. 3 is an A-A sectional view among Fig. 1.

The specific embodiment

Consult Fig. 1, Fig. 2, shown in Figure 3, the novel lengthened dipper of a kind of excavator comprises back lower cover 1, preceding lower cover 2, box-shaped intensive aspect 3, termination 4, front side board 5, latus inframedium 6, back side panel 7, rear upper plate 8, middle upper plate 9, preceding upper plate 10, strengthens gusset 11 etc.; Thereafter lower cover 1 welds with preceding lower cover 2, front side board 5, latus inframedium 6, back side panel 7 are welded to each other, and with the two sides welding of back lower cover 1 and preceding lower cover 2, and weld seam staggers mutually, and rear upper plate 8, middle upper plate 9, preceding upper plate 10 are welded to each other, and be welded on the front side board 5, latus inframedium 6 of two sides, above the back side panel 7, and weld seam staggers mutually, constitute the rectangle hollow dipper thus, be welded with number in the dipper and strengthen gusset 11, the dipper front end is inserted and be welded in termination 4; For satisfying instructions for use, can be with the working portion lengthening 0.85-1.5 rice of dipper postmedian; Owing to cancelled the arc nest deformation section structure of existing dipper, have additional a box-shaped intensive aspect 3 in preceding lower cover 2 bottom surfaces especially, carry out local stiffening, to gain in strength, box-shaped intensive aspect 3 front portions are the inclined-plane, the rear portion is a cambered surface.

Claims

1. novel lengthened dipper of excavator, comprise lower cover, termination, side plate, upper plate, thereafter lower cover and preceding lower cover welding, before, during and after side plate be welded to each other and with the welding of the two sides of front and back lower cover, before, during and after upper plate be welded to each other and be welded on two sides before, during and after above the side plate, constitute hollow dipper thus, be welded with the reinforcement gusset in the dipper, the termination connects firmly at the dipper front end; It is characterized in that described preceding lower cover (2) bottom surface is provided with a box-shaped intensive aspect (3).

2. the novel lengthened dipper of excavator according to claim 1 is characterized in that described box-shaped intensive aspect (3) front portion is the inclined-plane, and the rear portion is a cambered surface.

3. the novel lengthened dipper of excavator according to claim 1 is characterized in that the working portion lengthening 0.85-1.5 rice of described dipper postmedian.
