Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engineering machinery, in particular to a reinforced bucket structure. Background Art
[0002] A bucket refers to the bucket installed on an excavator, also called a digging bucket. According to the working method, it is divided into a backhoe bucket and a front shovel bucket. The backhoe bucket is commonly used.
[0003] The inventor discovered the following technical problems:
[0004] (1) The bucket structure cannot adapt to the existing large and super large excavators. Bucket cracking problems often occur in the market. Please refer to the attached Figure 1 There is no reinforcement feature on the outside of the rear part of the excavator bucket. When the bucket is excavating, the main stress-bearing parts are the ear plate and the support plate, which have weak ability to resist deformation. The market increases the structural strength by increasing the plate thickness, but simply increasing the plate thickness will increase the manufacturing cost;
[0005] (2) When the bucket is used to dig rocks, in most cases only a single tooth on each side of the bucket is used for digging. Figure 2 The front blade of the existing bucket is a straight surface with no protruding parts. After the bucket teeth are assembled, they are on the same horizontal plane. When the bucket is used for single-sided excavation, the force point is the center of the bucket tooth. The straight-line distance between the force point and the fixed center of the bucket is longer, and the torque on the rear of the bucket is larger, resulting in cracks caused by frequent knocking. Utility Model Content
[0006] The utility model aims to provide a reinforced bucket structure, which can solve the technical problem of the existing bucket being too low.
[0007] To achieve the above purpose, the utility model proposes a reinforced bucket structure, including a bucket body, an ear plate and a front edge plate, wherein the rear side of the bucket body is provided with an ear plate, an ear plate pasting plate is installed on the side wall of the ear plate, a support plate is installed on the side wall of the ear plate, and a plurality of reinforcing ribs are installed on the side wall of the support plate;
[0008] A front blade plate is arranged at the front side of the bucket body, arc steps are arranged at two ends of the front blade plate, and bucket teeth are evenly distributed on the front blade plate.
[0009] It is further configured that a tooth guard is arranged between the tooth guards, and the tooth guard is covered and fixed on the front blade plate.
[0010] It is further configured that the mouthguard is obliquely arranged corresponding to the arc-shaped step, and the mouthguard is covered and fixed on the arc-shaped step.
[0011] It is further configured that the bucket tooth is fixedly mounted on the front edge plate via a tooth seat.
[0012] It is further configured that the support plate is a V-shaped plate, and the reinforcing ribs are evenly arranged along the outer wall of the support plate.
[0013] It is further configured that the reinforcing rib is a trapezoidal plate, and the height of the reinforcing rib decreases in a direction away from the ear plate.
[0014] It is further configured that the large end surface of the reinforcing rib is fixedly connected to the ear plate.
[0015] It is further configured that the bucket body is surrounded by a lower side plate, a rear wall plate and an upper side plate.
[0016] It is further configured that the lower end of the ear plate is fixedly connected to the rear wall plate.
[0017] It is further configured that a hanging hole is provided through the ear plate and the ear plate attached plate.
[0018] Beneficial effects of one or more of the above technical solutions:
[0019] (1) To address the problem of weak force concentration on the bucket ear plate and support plate, an ear plate contact plate is added to the bucket ear plate, and trapezoidal reinforcement ribs are set on the support plate to enhance the ability of the ear plate and support plate to resist deformation. Compared with simply increasing the plate thickness, adjusting the structure is more cost-effective.
[0020] (2) By adjusting the shape of the front blade plate and the position of the tooth seat, the front blade plate is in a convex state, and the bucket teeth are not in the same horizontal plane after assembly. After the adjustment is completed, the bucket tooth that contacts the rock when the bucket is buckling the stone will change from the original one bucket tooth to two bucket teeth, so that the excavation process changes from the original single-tooth excavation to double-tooth excavation. This can reduce the torque generated when using the bucket for single-sided excavation and avoid the occurrence of bucket cracking. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The specific implementation of this embodiment is described below in conjunction with the accompanying drawings.
[0031] A reinforced bucket structure, referring to Figure 3 , a bucket body 1, an ear plate 2 and a front edge plate 4, the ear plate 2 is arranged on the rear side of the bucket body 1, the ear plate 2 is installed on the side wall of the ear plate 2, the support plate 3 is installed on the side wall of the ear plate 2, and a plurality of reinforcing ribs 31 are installed on the side wall of the support plate 3. By reinforcing the bucket connecting seat, the ability of the bucket connecting seat to resist deformation is enhanced.
[0032] Reference Figure 4 A front blade plate 4 is provided on the front side of the bucket body 1, and arc steps 41 are provided at both ends of the front blade plate 4. Bucket teeth 43 are evenly distributed on the front blade plate 4. The form of the front blade plate 4 is changed so that the bucket teeth 43 are not in the same horizontal plane after the bucket is assembled, so that the bucket can be used for single-sided excavation.
[0033] In order to prevent the front blade plate 4 from being damaged during excavation, guard teeth 44 are arranged between the bucket teeth 43. The guard teeth 44 cover and are fixed on the front blade plate 4. The guard teeth 44 wrap the front blade plate 4 and the guard teeth 44 bear the damage to the front blade plate 4 caused by external impact.
[0034] The tooth guard 44 is obliquely arranged corresponding to the arc-shaped step 41 , and the tooth guard 44 covers and is fixed on the arc-shaped step 41 .
[0035] The bucket tooth 43 is fixedly mounted on the front blade plate 4 through the tooth seat 42 to ensure stable installation of the bucket tooth 43 .
[0036] Reference Figure 3 The support plate 3 is a V-shaped plate, and the reinforcing ribs 31 are evenly arranged along the outer arc-shaped wall surface of the support plate 3 , and the reinforcing ribs 31 improve the strength of the support plate 3 .
[0037] The reinforcing rib 31 is a trapezoidal plate, and the height of the reinforcing rib 31 decreases in the direction away from the ear plate 2, forming an angle at the connection between the ear plate 2 and the support plate 3. The angle will cause stress concentration during use. Therefore, the trapezoidal reinforcing rib 31 is welded to the side walls of the ear plate 2 and the support plate 3.
[0038] The large end face of the reinforcing rib 31 is fixedly connected to the ear plate 2. The ear plate 21 is welded to the ear plate 2 and then to the support plate 3 to form a small weld of the connecting seat. After welding is completed, the reinforcing rib 31 is welded to the ear plate 2 and the support plate 3 respectively. After welding is completed, the bucket connecting seat is strengthened. The ability of the reinforced bucket connecting seat to resist deformation is significantly improved compared with before strengthening.
[0039] The bucket body 1 is surrounded by a lower side plate 11 , a rear wall plate 12 and an upper side plate 13 , and the lower side plate 11 , the rear wall plate 12 and the upper side plate 13 form a shell which is open at the top and closed at the bottom.
[0040] The lower end of the ear plate 21 is fixedly connected to the rear wall plate 12. The ear plate 21 is welded to the ear plate 2 and then welded to the support plate 3 to form a small weld of the connecting seat. A lifting hole 22 is opened through the ear plate 2 and the ear plate 21. The lifting hole 22 can be passed through a sling for lifting during lifting.
[0041] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
