Technical Field

[0001] This utility model belongs to the field of forklifts, and more specifically, relates to a forklift for civil engineering. Background Technology

[0002] A loader used in civil engineering typically refers to a heavy-duty construction machine used in civil engineering projects such as construction sites, road construction, and bridge construction to shovel, load, transport, and unload bulk materials (such as sand, gravel, soil, and concrete aggregate).

[0003] They are divided into wheel loaders and tracked loaders. Wheel loaders use tires to move, have good mobility, high speed, and are easy to move. They cause less damage to the road surface and are the most common type on civil construction sites. They are also commonly referred to as "shovel loaders".

[0004] Tracked loaders use tracks to move, resulting in low ground pressure, high traction, and good stability. They are suitable for working on soft, muddy, or rugged ground, but they are slow and inconvenient to move.

[0005] The bucket is the most crucial and forward-facing working device of a loader. It is directly responsible for scooping, holding, and unloading materials, and its design, materials, and condition directly determine the loader's operating efficiency, fuel consumption, and service life.

[0006] Currently, the buckets of loader trucks on the market are of a fixed size. When the size needs to be adjusted during project use, another loader truck with a different bucket size is required to perform the task. For the project, this increases the maintenance costs of the loader truck and also increases the waiting time for loader truck tasks. Utility Model Content

[0007] To address the above deficiencies, this utility model provides a loader for civil engineering, including a loader body, wherein the tilting cylinder of the loader body is connected to the bucket via the boom, and the bucket includes two movable shovels and one fixed shovel.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 3 As shown, this embodiment provides a loader for civil engineering, including a loader body 1. The tilting cylinder of the loader body 1 is connected to the bucket 6 via the boom 2, which is the same as the structure and usage of existing loaders. The bucket 6 has two movable shovel plates 602 and one fixed shovel plate 601. The top of the fixed shovel plate 601 is connected to a positioning plate 61. Limit seats 62 are fixed on both sides of the positioning plate 61. The sliding grooves 63 of the two limit seats 62 are movably connected to the movable shovel plates 602. The movable connection is achieved by having a sliding rod in each limit seat 62. 64. Two sliding rods 64 are welded to the left and right sides of the positioning plate 61 respectively and are located on the same horizontal line. The top of the two movable shovel plates 602 on the opposite side are slidably connected to the adjacent sliding rods 64 through the welded sliding seat 65. The sliding seat 65 is sleeved on the outside of the sliding rod 64. In addition, in order to ensure that the boom 2 can drive the bucket 6 to rotate normally and synchronously, the sliding rod 64 needs to be set as a four-sided rod. Compared with the traditional cylindrical shape, synchronous rotation can be achieved through the matching ridge surface. The far end of the sliding rod 64 is fixed with a limit blade to prevent it from falling off during sliding.

[0022] The insertion ends 603 of the two movable shovel plates 602 are inserted into the through slots 604 inside the fixed shovel plate 601. The through slots 604 allow the fixed shovel plate 601 to be passed through from both sides. Specifically, magnets 608 are embedded in the ends of the two insertion ends 603 that are close to each other, and the two magnets 608 have opposite magnetic poles, which facilitates the positioning and fixing effect after retraction (the bucket 6 is made of steel, the same material as the bucket on a traditional forklift). Side plates 5 are fixed to the ends of the two movable shovel plates 602 that are far from each other. Linkage plates 4 are fixed to the top of the two side plates 5, and a middle plate 3 is provided between the two linkage plates 4 on the sliding seat 65. The middle plate 3 is fixed to the top of the positioning plate 61. It should be noted that the two linkage plates 4 and the middle plate 3 are set separately. Figure 3 As shown, the linkage plate 4 is integrally formed from a triangular plate and a flat plate, while the side plate 5 is fixed to the movable shovel plate 602 and also to the linkage plate 4. The three can be regarded as a whole and perform synchronous overall movement.

[0023] The bottom edge of the bucket 6 is also welded with several equally spaced shovel teeth 605. The shovel teeth 605 located at the movable shovel plate 602 are solid. The shovel teeth 605 located at the fixed shovel plate 601 have a tooth hole 606 with the same diameter as the through groove 604. The shovel teeth 605 located at the insertion end 603 are short shovel teeth 607 that can be inserted into the tooth hole 606. Their function is to ensure that there are shovel teeth 605 available for use whether the movable shovel plate 602 is extended or retracted.

[0024] like Figure 3As shown, the connecting end of the boom 2 is fixed to the back of the fixed shovel plate 601. Two opposing electric cylinders 7 are installed on the back of the positioning plate 61. The output ends of the two electric cylinders 7 are respectively fixed to the connecting seats 8 fixed to the top of the two linkage plates 4. The two electric cylinders 7 drive their respective connected connecting seats 8 synchronously through extension and retraction, thereby synchronously driving the side plate 5, the movable shovel plate 602 and the linkage plate 4, which are regarded as a whole, to move synchronously. This enables the movable shovel plate 602 to extend or retract relative to the fixed shovel plate 601, thereby adjusting the size of the bucket 6. It should be noted that the maximum extension distance of the electric cylinder 7 should be less than the width of the insertion end 603 to prevent gaps from forming between the insertion end 603 and the fixed shovel plate 601, which would affect the normal shoveling work.

[0025] It should be noted that the structure described in this utility model can be implemented in many different forms and is not limited to the embodiments described. Any equivalent transformations made by those skilled in the art based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, such as the loading and unloading of other items, are included within the protection scope of this utility model.
