Abstract
Description
Technical Field
[0001] This utility model relates to the field of loader technology, and in particular to a reinforced A-type log fork for a loader. Background Technology
[0002] In modern forestry, timber processing, and logistics, loaders are crucial material handling equipment, and the performance of their attachments directly impacts operational efficiency and safety. Currently, among loader attachments used for grabbing logs, the A-frame log fork is a common type, widely used due to its simple structure and ease of operation.
[0003] However, when faced with the task of grabbing heavier logs, the technical shortcomings of existing A-frame log grabbing forks become increasingly apparent. From a structural strength perspective, there is room for improvement in the material selection, cross-sectional design, and welding processes of key components such as the fork and support arm of existing log grabbing forks, resulting in slightly weaker overall structural strength. During the grabbing of heavy objects, the fork is subjected to significant bending moments and shear forces, making it prone to deformation, cracking, and other damage at stress concentration points. This not only increases equipment maintenance costs but also poses a safety hazard due to sudden component failure, endangering operators and the surrounding environment.
[0004] In terms of operational efficiency, the existing A-frame log grabbing fork has a significant drawback: its small opening size. When using the downward-folding grabbing fork to lift the log, the small opening limits the grabbing range and angle, requiring multiple adjustments to complete the grabbing, thus extending the single-operation time and reducing overall operational efficiency. Utility Model Content
[0005] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a reinforced A-type log fork for a loader.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] Design a reinforced A-type log fork for a loader, including a lower claw and an upper claw. There are two lower claws, which are connected by a first connecting rod and a second connecting rod, respectively. An upper claw is provided on one side of each lower claw. One end of each upper claw is sleeved on the outer wall of the first connecting rod. A baffle is fixedly installed on the other end of the upper claw. The baffle is A-shaped, and the two bottom corners of the baffle are fixedly connected to the upper claw, respectively.
[0008] Furthermore, the baffle is provided with an arc shape at its top corner that curves downwards towards the claw.
[0009] Furthermore, a crossbar is fixedly installed between the two upper claws to connect the two upper claws together.
[0010] Furthermore, a reinforcing plate is provided at the top corner of the baffle on the side away from the lower claw.
[0011] Furthermore, a first connecting block and a second connecting block are provided between the first connecting rod and the second connecting rod. There is one second connecting block, which is located in the middle position. There are two first connecting blocks, which are respectively located on both sides of the second connecting block. One end of the first connecting block and the second connecting block is provided with a mounting hole for connecting to the loader.
[0012] Furthermore, the two lower claws are respectively placed on both sides of the baffle.
[0013] The present invention proposes a reinforced A-type log fork for a loader, which has the following advantages: it can clamp larger and more logs, while the clamping radius is smaller, making it more stable when grabbing. In addition, the upper claw has better force distribution, resulting in higher safety. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figure 1-5A reinforced A-type log fork for a loader includes a lower claw 1 and an upper claw 2. There are two lower claws 1, which are connected by a first connecting rod 3 and a second connecting rod 4. The first connecting rod 3 and the second connecting rod 4 are used to connect the two lower claws 1 and serve as lateral support to fix the lower claws 1. At the same time, the first connecting rod 3 can also connect the lower claws 1 and the upper claws 2 together. An upper claw 2 is provided on one side of each lower claw 1. One end of each upper claw 2 is sleeved on the outer wall of the first connecting rod 3. A baffle 5 is fixedly installed on the other end of the upper claw 2. The baffle 5 is A-shaped, and the two bottom corners of the baffle 5 are fixedly connected to the upper claw 2.
[0022] With its lower claw 1, upper claw 2, and baffle 5 design, the opening is larger than that of the traditional A-shaped log fork, allowing it to clamp larger and more pieces of wood. At the same time, the clamping radius is smaller, making it more stable when gripping. In addition, the upper claw 2 has better force distribution, resulting in higher safety.
[0023] The top corner of the baffle 5 is designed with an arc that curves downwards towards the claw 1, which can better grip the wood. Compared to a straight line, it can better block the wood and prevent it from falling during the gripping process, thus improving the safety of the device.
[0024] A crossbar 7 is fixedly installed between the two upper jaws 2 to connect the two upper jaws 2 together.
[0025] A reinforcing plate 6 is provided at the top corner of the baffle 5 on the side away from the lower claw 1. Multiple reinforcing plates 6 are evenly distributed to increase the strength of the arc-shaped part. This can effectively disperse the pressure and bending moment borne by the arc-shaped part when gripping the wood, and avoid problems such as arc deformation and local dents caused by the pressure of heavy objects during gripping. This ensures the stable clamping of the wood by the wood-grabbing fork during the gripping process, and further improves the structural reliability and safety of the equipment during operation.
[0026] A first connecting block 8 and a second connecting block 9 are provided between the first connecting rod 3 and the second connecting rod 4. There is one second connecting block 9, which is placed in the middle position. There are two first connecting blocks 8, which are placed on both sides of the second connecting block 9 respectively. One end of the first connecting block 8 and the second connecting block 9 is provided with a mounting hole for connecting with the loader. This design can not only connect the loader, but also increase the overall strength of the lower claw 1.
[0027] The two lower claws 1 are respectively placed on both sides of the baffle 5. By staggering the baffle 5 and the lower claws 1, the baffle 5 can be embedded between the lower claws 1, thereby making the clamping radius between the baffle 5 and the lower claws 1 smaller, which can be more stable and also improve the applicability.
[0028] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
