Problems solved by technology

[0003] Existing buckets are formed by welding multiple steel plates. Since the steel plates cannot be completely connected along the welds, it is easy to crack and deform along the welds during use and be scrapped.

Embodiment Construction

[0020] The integral cast steel bucket of the present invention is composed of bucket ears 3, bucket body 4 and tooth seat 5, which are manufactured as a whole by casting method. When the bucket 2 is in use, the bucket ear 3 is connected to one end of the forearm 1 of the excavator (see figure 1 shown).

[0021] The manufacturing method of described monolithic cast steel bucket is:

[0022] a. Manufacture the model 10 according to the shape of the bucket, and the model 10 is made of polystyrene material, which is what we usually call the lost foam;

[0023] b. Brush the refractory paint on the surface of the model 10, and form a hard shell after drying;

[0024] c. Put the model 10 and the pouring system 6, 7 into the sand box 11 at the same time, fill in the dry sand 9, vibrate, and cover the plastic film 8 on the top of the sand box 11;

[0025] d. Start the vacuum pump to empty the air in the sand box 11 through the vacuum pipeline 12, so that the dry sand 9 has a certain...

Abstract

The invention relates to an integral cast steel dredge bucket. The dredge bucket consists of a bucket ear, a bucket body and a teeth seat, wherein the bucket ear, the bucket body and the teeth seat are made into a whole body by using a casting method. The dredge bucket is manufactured by using a lost foam shell casting method; the dredge bucket is cast into a whole body by using alloy steel as a raw material; and after the casting process is finished, the base is strengthened by thermal treatment; and thus the mechanical strength and the wearing resistance of the dredge bucket are improved and the probability of deformation and cracking of the bucket wall caused by over-large partial stress is reduced, so that the service life is prolonged.

Description

technical field [0001] The invention relates to an integral cast steel bucket. Background technique [0002] The bucket is a part used on the excavator. All the operations of the excavator are centered on the bucket, so its function is very important. [0003] Existing buckets are welded after forming by adopting multiple steel plates. Since the steel plates cannot be completely connected along the weld seam, it is easy to crack and deform along the weld seam during use and be scrapped. Contents of the invention [0004] The object of the present invention is to overcome the defects of the above-mentioned prior art, and provide an integral cast steel bucket that prevents the bucket wall from cracking and deforming and prolongs the service life of the bucket. [0005] To achieve the above object, the present invention adopts the following technical solutions: [0006] An integral cast steel bucket, which is composed of bucket ears, bucket body and tooth seat, is character...
