The mode of company of reinforcing plate and main cutting board has two kinds at present: one is that the reinforcing plate 01 shown in figure 1 is connected with the main cutting plate 02 in a butt welding way; the connecting mode has the problems that the structural strength of the bucket body is low, and the bucket bottom is easy to bump into the ground when impacting the ground in the flat ground operation, so that the bucket bottom plate is easy to fatigue and damage. Secondly, as shown in fig. 2, the reinforcing plate 001 is welded with the main blade 002 through the reinforcing rib 003, a cavity is formed between the reinforcing plate 001 and the bucket bottom plate 004 due to the structure, the reinforcing rib 003 and the reinforcing plate 001 cannot be welded due to the small cavity of the cavity, the reinforcing plate 001 and the main blade 002 are butt-welded, and the weld is severe in load and easy to wear; in the flat ground operation, when the bottom of the bucket hits the ground, although the strength is guaranteed, the processing technology requirement is higher, the consumables are wasted, and the production efficiency is low.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that an engineering machine tool bucket is provided to solve the problem that current engineering machine tool bucket intensity is not enough and production efficiency is low.
The utility model provides a technical scheme that technical problem adopted does: the engineering machinery bucket comprises a bucket body provided with a bucket bottom plate, wherein the front end of the bucket bottom plate is connected with a main cutting board, a reinforcing plate is arranged on the outer surface of the bucket bottom plate close to the main cutting board, a step groove is formed in the bottom surface of the main cutting board close to the bucket bottom plate, and the front end of the reinforcing plate is lapped on the step groove of the main cutting board.
In the above technical solution of the construction machinery bucket, a more specific technical solution may also be: the step groove is provided with a lapping surface which is low in the front and high in the back, the front end of the reinforcing plate is welded on the lapping surface of the step groove, and the back end of the reinforcing plate is welded and connected with the bucket bottom plate.
Further: the bucket bottom plate is connected with the shaft seat, and side sealing plates are arranged on two sides of the bucket bottom plate.
Further: each side seal plate is connected with a cutting board at the front end.
Further: the two knife boards are respectively connected with the main knife board.
Further: and a plurality of auxiliary reinforcing plates are arranged on the outer surface of the bucket bottom plate from the position close to the shaft seat to the position close to the reinforcing plates.
The utility model relates to a front is the direction of the engineering machinery bucket.
Since the technical scheme is used, compared with the prior art, the utility model following beneficial effect has: 1. because the step groove on the side of the main cutter plate close to the bucket bottom plate is provided with the lap joint surface with the lower front part and the higher rear part, the reinforcing plate and the main cutter plate are in lap joint, the production efficiency is improved, the reinforcing plate and the main cutter plate form a stress beam frame, the butt joint connection is avoided at the position with severe load, the bucket body is protected, and the strength of the engineering machinery bucket is enhanced; when the engineering machinery bucket loads materials on the hard ground, the bucket can be attached to the ground without damaging the ground; when the bucket of the engineering machinery impacts the ground, the force borne by the reinforcing plate is relieved through the side sealing plates and the knife plates on the two sides, so that the rigidity and the strength of the bucket are increased, the structure is simple, and the maintenance is convenient; in addition, the weld joint between the reinforcing plate and the main cutting plate is prevented from being subjected to shear load, the side surface is stressed, the reliability is further improved, and the service life is prolonged; 2. compared with the existing mode that the reinforcing plate is connected with the main cutter plate in a butt welding mode, the strength and the rigidity of the engineering machinery bucket are guaranteed, and the service life is prolonged; compared with the mode that the reinforcing plate is connected with the main cutter plate in a welding mode through the reinforcing ribs, the welding seam of the engineering machinery bucket is prevented from being subjected to shearing load, the side face of the bucket is stressed, and the reliability is further improved; meanwhile, reinforcing ribs are omitted, the material types are reduced, the production efficiency is improved, and the production cost is saved.

Detailed Description
The invention is described in detail below with reference to the accompanying drawings:
as shown in fig. 3 and 4, the construction machinery bucket comprises a bucket body provided with a bucket bottom plate 5, the front end of the bucket bottom plate 5 is welded with a main cutting board 2, the bucket body of the embodiment further comprises a shaft seat 3, the shaft seat 3 is welded with the rear end of the bucket bottom plate 5, two sides of the bucket bottom plate 5 are respectively provided with a side sealing plate 6, the front end of each side sealing plate 6 is welded with one cutting board 4, and the lower ends of the two cutting boards 4 are respectively welded with two sides of the main cutting board 2; the outer surface of the bucket bottom plate 5 close to the main cutter plate 2 is provided with a reinforcing plate 1, the bottom surface of the main cutter plate 2 close to the bucket bottom plate 5 is provided with a step groove, the step groove is provided with a lapping surface which is low in front and high in back, the front end of the reinforcing plate 1 is welded on the lapping surface of the step groove, and the back end of the reinforcing plate 1 is welded with the bucket bottom plate 4; a plurality of auxiliary reinforcing plates 7 are welded on the outer surface of the bucket bottom plate 4 from the position close to the shaft seat 3 to the position close to the reinforcing plate 1, so that the strength of the bucket bottom plate 5 is increased.
Because the step groove of the nearly bucket bottom plate 5 side of main cutting board 7 is equipped with the high faying face in front low back for reinforcing plate and main cutting board are the overlap joint welding seam, and the welding seam is arranged rationally, avoids the butt weld to be connected in the abominable department of load, has cancelled the strengthening rib that bucket bottom plate 5 and reinforcing plate 1 are connected simultaneously, makes reinforcing plate 1 and main cutting board 2 form a atress roof beam structure, has improved the intensity and the rigidity of scraper bowl, has protected the scraper bowl body. When the engineering machinery bucket loads materials on the hard ground, the bucket can be attached to the ground without damaging the ground; when the bucket of the engineering machinery impacts the ground, the force borne by the reinforcing plate 1 is relieved through the side sealing plates 6 and the knife boards 4 on the two sides; in addition, the weld joint of the reinforcing plate 1 and the main cutter plate 2 is prevented from being subjected to shearing load, the side surface is stressed, the reliability is further improved, and the service life is prolonged.
