Description

Technical Field

[0001] This utility model belongs to the technical field of excavator attachments and equipment, and relates to a screening bucket bow-shaped frame type frame. Background Technology

[0002] A screening bucket is a functional attachment for engineering machinery adapted to excavators. Its main function is to perform operations such as screening, crushing, aerating, mixing, and separating solid materials. Its main structure consists of four parts: the attachment connection frame, the frame, the screening bucket, and the transmission system. The frame is a crucial part of the overall structure of the screening bucket. The attachment connection frame and the transmission system are both mounted on the frame. The load during the screening bucket's operation is directly applied to the frame, and during material handling, the frame directly functions as the bucket. Therefore, the overall stress on the screening bucket frame is quite complex. Thus, the structural design of the screening bucket frame plays a vital role in the overall stability and safety of the screening bucket.

[0003] Currently, the frame structure design of screening bucket machines mainly falls into two categories: frame type and box beam type. Among them, the frame type frame typically uses profiles or steel plates welded into a cage, with the screening bucket placed inside. This structure boasts strong static load-bearing capacity, simple structure, and ease of manufacturing, making it the most widely used frame type. However, because the frame type frame uses an integrated frame, deformation at any point in the frame is directly transmitted to the screening bucket or transmission system, easily leading to premature failure of the transmission system. Furthermore, due to the frame structure, the operating space is limited when loading, unloading, and maintaining the screening bucket, making maintenance inconvenient. Box girder frames are mostly used for small-tonnage screening buckets. They use curved box girders as the main structure for mounting attachments and the transmission system. The bucket part of the frame is not directly connected to the mounting part for the transmission system. One end of the bucket is fixed and the other end is free. When shoveling and transporting materials, the structure has a certain degree of elasticity, which can achieve energy absorption and buffering. When using a box girder frame, the sides and bottom of the bucket are open, providing a large operating space for loading, unloading and maintenance of the bucket, and making maintenance convenient. However, because the box girder frame is cantilevered, its torsional and bending stiffness is significantly lower than that of a frame frame for the same weight. In addition, the manufacturing difficulty and cost of curved box girders are relatively high.

[0004] In summary, existing technologies suffer from problems such as inconvenient frame maintenance and high manufacturing difficulty and cost. Utility Model Content

The two sides of the end of the top connecting beam are connected to the upper arch arm plate and the arch beam plate respectively.

[0012] A foot pad is connected to the end of the lower bow arm plate away from the bow beam plate.

[0013] The bucket structure includes an upper baffle, one side of which is fixed to the front connecting beam. Shovel side plates are respectively attached to both ends of the upper baffle. One end of the shovel side plate is connected to the end of the front connecting beam, and the other end is connected to the shovel lip.

[0014] An inner bending plate is attached to the shovel lip and the shovel side plate, respectively; a guide plate is attached to the inner bending plate near the upper baffle.

[0040] This embodiment proposes a screening bucket bow-shaped frame frame, including a front connecting beam 117, bow-shaped side frames at both ends of the front connecting beam 117, a top connecting beam 105 and a tail connecting beam 118 connecting the bow-shaped side frames, and a bucket structure on one side of the front connecting beam 117 between the bow-shaped side frames.

An inner bent plate 111 is attached to the side of the shovel lip 112 closest to the side plate 110, and the inner bent plate 111 is fixedly connected to both the shovel lip 112 and the side plate 110.

Roller support plates 122 are attached to the side walls of the side plate reinforcing plate 114 near the shovel side plate 110. Roller support plates 121 are provided on the roller support plates 122.

[0042] In this embodiment, the screening bucket bow-shaped frame 1, as shown... Figure 1 and Figure 2 As shown, the lower bow arm plate 101, bow beam plate 102, and upper bow arm plate 103 are connected to each other to form a bow arm structure. The two ends of the lower bow arm plate 101 and the upper bow arm plate 103 are connected together by the bow arm connecting plate 115 to form a bow-shaped side frame. The two bow-shaped side frames are connected together by the top connecting beam 105, the front connecting beam 117, and the tail connecting beam 118 to form a bow-shaped frame main frame structure. The tail connecting beam 118 is connected to the tail reinforcing column 116. The tail cylinder fixing plate 119 and the motor box 104 are connected to the tail connecting beam 118 and the tail reinforcing column 116.

[0043] Combination Figure 2 and Figure 3 As shown, the tail cylinder fixing plate 119 of the arched frame frame 1 of the screening bucket is used to install the screening bucket 3 and the transmission system 4, and the motor box 104 is used to protect the transmission system 4. The main frame structure of the arched frame is formed by the lower arch arm plate 101, the arch beam plate 102, the upper arch arm plate 103, the arch arm connecting plate 115, the top connecting beam 105, the front connecting beam 117, and the tail connecting beam 118, which mainly plays a role in bearing and supporting the screening bucket 3 and the transmission system 4.

[0044] The front connecting beam 117, upper baffle 109, shovel side plate 110, inner bending plate 111, shovel lip 112, guide plate 113, and side plate reinforcing plate 114 of the arched frame frame 1 of the screening bucket together form the bucket section of the arched frame frame 1. The upper baffle 109 prevents materials from directly impacting or abrading the front connecting beam 117, thus preventing damage to the main frame structure. The inner bending plate 111 connects the shovel side plate 110 and shovel lip 112 and guides the material into the screening bucket 3. The shovel lip 112 scoops up material and enters the screening bucket 3. The guide plate 113 covers the gap between the inner bending plate 111 and the screening bucket 3, guiding the material into the screening bucket 3. The side plate reinforcing plate 114 protects the shovel side plate 110 during material scooping, preventing wear on the shovel side plate 110.

[0045] The top plate 106 of the screening bucket bow-shaped frame 1 is connected to the top connecting beam 105. The top plate 106 is used to connect the attachment connecting frame 2. The top beam connects the square column 107 and the top reinforcing column 108 to strengthen the top of the screening bucket bow-shaped frame 1. When the material is being transported, the load of the shovel lip 112 will be transferred to the front connecting beam 117, so that the deformation only acts on the shovel lip 112 and the shovel side plate 110 of the screening bucket bow-shaped frame 1.

[0046] The inner side of the shovel side plate 110 in the screening bucket bow-shaped frame 1 is connected to a roller support plate 122. A roller assembly 121 is installed on the roller support plate 122. The roller assembly 121 is used to support the screen bucket 3, offset the additional bending moment caused by the sinking and shaking of the screen bucket 3 to the transmission system 4, and reduce the jumping when the screen bucket 3 rotates. The roller assembly 121 does not restrict the axial freedom of the screen bucket 3 at this location. When the material is being transported, the axial deformation of the shovel lip 112 and the shovel side plate 110 cannot be transmitted to the transmission system 4 through the screen bucket 3. The lower end of the lower bow arm plate 101 in the screening bucket bow-shaped frame 1 is connected to a foot pad plate 120. The foot pad plate 120 and the shovel lip 112 are used to place the screening bucket.

[0047] This utility model adopts an arc-shaped frame structure 1, which retains the advantages of high rigidity, low cost and low manufacturing difficulty of the frame frame, and also retains the good toughness of the box beam frame. The bucket part of the frame has a certain elastic deformation space, which can effectively protect the transmission system. Compared with the frame frame, it has a larger construction operation space when loading, unloading and maintaining the screen bucket.
