Abstract

The utility model discloses a sliding loader arm, which comprises a boom (3), a boom driving device (4), a short rocker (7), a long rocker (5) and a vehicle frame (6). One end of the rod (7) is hinged to the vehicle frame (6), and the other end is hinged to the tail end of the moving arm (3). The new boom of the skid steer loader provided by the utility model, under the drive of the boom driving device (4), the long rocker (5) moves upward and forward, and the short rocker (7) first moves backward and then forward, During the lifting process, the driving device moves between the hinge points of the long rocker (5) to avoid interference and not affect the strength of the long rocker (5). The advantage is that the boom driving device (4) obtains a greater effective component force through the cooperation of the rod group to push the working device to lift the material, saves energy consumption during the lifting process, and obtains an approximately vertical material lifting path, making the machine more stable , the loading and unloading distance increases.

Description

skid steer loader arm

technical field

The utility model relates to a skid loader, in particular to a skid loader arm.

Background technique

At present, the rear end of the arm of the general loader is directly hinged with the vehicle frame, and the boom is driven to move in an arc with the frame hinge point as the circle point during work. In the utility model, a four-link mechanism is formed by connecting the boom and the vehicle frame of the skid steer loader through a long rocker and a short rocker. This working device can realize approximately vertical lifting of loaded materials. Compared with the loader working device whose boom is directly fixed on the frame and performs circular arc movement, this working device enables the loader to obtain greater lifting capacity, lifting height and unloading distance under the same lifting force. Improved work efficiency and loading capacity.

Utility model content

The technical problem to be solved by the utility model is to provide a skid steer loader arm capable of vertical lifting of materials, large lifting capacity, long unloading distance, convenient operation, low cost and safe use.

In order to solve the above-mentioned technical problems, the skid steer loader arm provided by the utility model includes a boom, a boom driving device, a short rocker, a long rocker and a frame, one end of the short rocker is hinged to the frame, and the other One end is hinged to the rear end of the boom, one end of the long rocker is hinged to the frame, the other end is hinged to the boom, one end of the boom driving device is hinged to the frame, and the other end is hinged to the frame. The boom articulation described above.

The skid-steer loader arm adopting the above-mentioned technical scheme adopts the curve characteristic of the connecting rod of the four-bar mechanism to realize approximately vertical lifting of materials and reasonable mechanical properties. The boom and the frame are connected by a long rocker and a short rocker to form a four-bar linkage, and this working device can achieve approximately vertical lifting of loaded materials. Compared with the loader working device whose boom is directly fixed on the frame and performs circular arc movement, this working device enables the loader to obtain greater lifting capacity, lifting height and unloading distance under the same lifting force. Improved work efficiency and loading capacity. During the lifting process, driven by the boom driving device, the long rocker moves upwards and forwards, and the short rocker rotates backwards and then forwards. During the lifting process, the driving device moves between the two hinge points of the long rocker. Avoid interference without compromising the strength of the long rocker.

To sum up, the utility model adopting the above technical solution not only realizes the vertical lifting of materials, obtains a large lifting capacity and a longer unloading distance, but also ensures the mechanical strength and stability of the working device.

Fig. 2 is a schematic diagram of folding of the utility model.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described.

Referring to Fig. 1 and Fig. 2, the head of boom 3 is equipped with bucket 1 and its bucket cylinder 2, one end of short rocker 7 is hinged with vehicle frame 6, the other end is hinged with tail end of boom 3, and one end of long rocker 5 is Hinged on the vehicle frame 6, the other end of the long rocker 5 is hinged with the boom 3, one end of the boom driving device 4 is hinged on the vehicle frame 6, and the other end of the boom driving device 4 is hinged with the boom 3.

Referring to Fig. 1 and Fig. 2, the boom 3 and the frame 6 are connected by the long rocker 5 and the short rocker 7 to form a four-bar linkage mechanism. This working device can realize the approximate vertical lifting of the bucket 1 loaded material. Compared with the loader working device that is directly fixed on the vehicle frame 6 with the boom 3, the working device enables the loader to obtain greater lifting capacity, lifting height and unloading distance under the same lifting force. Improved work efficiency and loading capacity. During the lifting process, under the drive of the boom driving device 4, the long rocker 5 moves upward and forward, and the short rocker 7 first rotates backward and then forward. Movement between points not only avoids interference but also does not affect the strength of the long rocker 5.
