Abstract

The utility model discloses a bucket wall structure of a digging bucket of a loading machine, which comprises a bucket wall plate, L-shaped steel, a plurality of support plates which are in uniform arrangement and angular steel, wherein the bucket wall plate is bended for forming a bucket body, and the support plates are fixed on the surface of the bucket wall plate opposite to the bucket body, wherein the bucket wall structure also comprises a folding and bending plate which comprises a bucket wall part and a bending and folding part, wherein the parts of the bucket wall part and the bucket wall plate near the top ends are in mutual lap joint and are fixedly welded, the edges of two connecting corners of the L-shaped steel are respectively connected with the surfaces of the bucket wall part of the bucket wall plate and the folding and bending plate opposite to the bucket body, the bending and folding part of the folding and bending plate is bended and folded in the direction opposite to the bucket body, and is fixedly welded with the top part of the angular steel. The bucket wall structure of the utility model does not need large-area steel plates for making the bucket wall plates, and the digging bucket conforming the requirement can be produced only through using the standard steel plates.

Description

A kind of headwall structure of loading shovel

Technical field

The utility model relates to the structure of loading shovel, relates in particular to a kind of headwall structure of loading shovel.

Background technology

At present, the headwall structure of general loading shovel is essentially structure as shown in Figure 1, 2 on the market, is made up of headwall plate 1, transverse slat 6, gripper shoe 2 and angle steel 3.Headwall plate 1 is bent to form bucket body 4, and it is welded with gripper shoe 2 and angle steel 3 on face of bucket body 4 dorsad, and angle steel 3 is located at the position that headwall plate 1 relies on the top dorsad on the face of bucket body 4, and angle steel 3 welded top have transverse slat 6, and transverse slat 6 is fixing with angle steel 3 and 1 welding of headwall plate.The length requirement of headwall plate 1 is longer, and the steel plate of standard model is difficult to form satisfactory scraper bowl bucket body 4, thus often need the steel plate of specific size customized, the production technology relative complex, and cost of production improves.

Summary of the invention

It is low that the purpose of this utility model provides cost of production, the headwall structure of the loading shovel that stock utilization is high in the manufacturing process.。

For achieving the above object, headwall structure of the present utility model comprises the headwall plate, L shaped steel, the gripper shoe of a plurality of even settings and angle steel, the headwall plate is bent to form bucket body, gripper shoe is fixed in the headwall backboard on the face of bucket body, wherein, this headwall structure also comprises a bending plate, bending plate comprises headwall part and bending part, the part at described headwall part and the close top of headwall plate overlaps mutually and welds fixing, the limit of two joint angles of L shaped steel respectively with the headwall of headwall plate and bending plate part dorsad the face of bucket body link to each other, the bending part of bending plate is to the direction bending of bucket body dorsad, and the welded top of itself and angle steel is fixed.

In sum, compared with prior art, headwall structure of the present utility model does not need large-area steel plate to make the headwall plate, only uses the steel plate of standard model just can produce satisfactory scraper bowl.
