Description

Technical Field

[0001] The invention relates to the technical field of buckets, and in particular to a steering and positioning structure of a skid loader bucket. Background Art

[0002] The skid steer loader bucket is an important part of the skid steer loader and is used for various operations such as loading, digging, and handling. The skid steer loader bucket is generally composed of a cover plate, side plates, baffles, blades, corner edges, and side edges. Among them, the blade is the main cutting edge when the bucket digs materials and is located at the front of the lower end of the bucket. Holes are reserved on the blade for adding bucket teeth and auxiliary blades to enhance the wear resistance and service life of the bucket.

[0003] The material of the bucket has an important impact on its performance and service life. Common bucket materials include molten iron cast copper buckle steel plate, martensitic stainless steel plate and high-quality structural steel plate. These materials have excellent properties such as wear resistance, tensile strength and impact toughness, and can meet the use requirements under different working conditions.

[0004] The steering mechanism of the existing skid loader bucket is usually composed of a tie rod, a boom, a drive cylinder and other components. The bucket is driven by hydraulic power to steer relative to the boom. The traditional steering positioning structure is relatively complex, including multiple components and connection points, which increases the difficulty and cost of maintenance. At the same time, the complex structure may also lead to an increase in the failure rate.

[0005] In summary, the prior art lacks a technology for simplifying the steering and positioning structure of a skid steer loader bucket as much as possible while ensuring functionality and stability. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings existing in the background technology and to propose a steering positioning structure for a skid loader bucket.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is: a steering positioning structure of a skid loader bucket, comprising a frame, a swivel seat rotatably connected to the frame, a steering positioning mechanism being fixedly installed on the frame and the swivel seat, the steering positioning mechanism comprising an electric push rod A, an adjusting disk being fixedly connected to the electric push rod A, a plurality of positioning plug rods being slidably matched on one side of the adjusting disk in an annular structure, a spring being fixedly connected to the inner end of the positioning plug rod, and the other end of the spring being fixedly connected to the inner wall of the adjusting disk, a bucket being rotatably connected to the swivel seat, a positioning disk being fixedly connected to the bucket and the swivel seat, a plurality of positioning grooves being provided on the positioning plug rod, the positioning groove being movably plugged into the positioning groove, a pushing plate being slidably matched to the bucket, an adjusting frame being slidably matched in the bucket, a swivel frame being rotatably connected to the adjusting frame, and a bucket covering mechanism being rotatably connected to the swivel frame.

[0011] Preferably, an electric push rod B is fixedly connected to the bottom end of the adjusting frame, and the other end of the electric push rod B is fixedly connected to the inner wall of the bucket. A rotating shaft is rotatably connected to the middle of the adjusting frame, a driving wheel is fixedly connected to the top of the rotating shaft, and a driven wheel is fixedly connected to the middle of the rotating frame, and the driven wheel is meshed with the driving wheel for transmission.

The steering positioning mechanism in the present application has a relatively simple structure, which is convenient for replacement and maintenance, and reduces costs. At the same time, by setting a hydraulic cylinder B, it is possible to drive the bucket to rotate horizontally, thereby improving the flexibility of the bucket, which not only helps to improve the operating efficiency and quality of the loader, but also helps to expand its application scope and market prospects.

[0017] By setting a push plate on the bucket, objects on the bucket can be pushed out smoothly when transferring and unloading bricks or fragile items, avoiding the breakage of objects caused by direct dumping, reducing the splashing of materials during dumping, improving the cleanliness of the working area, avoiding the instability caused by dumping operations, reducing the risks to operators and the surrounding environment during operations, and reducing the problem of material scattering caused by dumping operations, thereby reducing subsequent cleaning work;

[0018] By setting up the bucket covering mechanism, the bucket covering mechanism can be conveniently stored on the adjustment frame and the rotating frame. At the same time, the bucket covering mechanism prevents small particles of materials from splashing, while maintaining a clear line of sight and improving operation safety. The covering can prevent materials or dust from contaminating the operating area or the surrounding environment, keep the working area clean, reduce the cleaning work caused by material splashing, and improve the continuity and efficiency of the operation. At the same time, when used outdoors on rainy days, the material can be covered and protected, thereby enhancing its adaptability under different working conditions.
