- the problem to be solved is the interference between the wheels and the lift arm when the entire length of the airframe including the loader is shortened, and the accompanying increase in the size of the intermediate link.
- the present invention takes the following means to solve the above-mentioned problems.
- the loading device of the present invention has a lift arm that is pivotally supported by a bracket fixed to a vehicle and pivoted up and down by a lift arm cylinder, and a lift arm at the front end of the lift arm. It has an attachment that is swingably supported, and a bucket link that is connected to the attachment and transmits the expansion and contraction of the bucket cylinder. A packet link and a bucket cylinder are connected to the intermediate link, and the lift arm and the bucket link are offset between the plates constituting the intermediate link.
- the lift arm fulcrum, the bucket cylinder fulcrum, and the lift arm cylinder fulcrum in the bracket fixed to the vehicle are present on the same plane.
- FIG. 1 is a side view of a loading device mounted on a work vehicle.
- FIG. 6 is a perspective view of the same.
- FIG. 10 is a diagram showing a packet dump state.
- FIG. 11 is a diagram showing the stroke setting of the bucket cylinder.
- the bucket link 15 offset to the lift arm 11 is disposed in the intermediate link 13, the bucket link 15 can be easily offset with respect to the lift arm 11.
- Fig. 10 is a diagram showing the packet dump state
- Fig. 10 (a) is an overall side view of the loader in the packet dump state
- Fig. 10 (b) is a side view showing the packet support unit in the packet dump state.
- the lift arm 11 and the bucket link 15 both support the packet 18 at the tip.
- the lift arm 11 and the bucket link 15 are rotatably connected to an attachment 19, and the packet 18 is attached to the attachment 19.
- the lift arm 11 is connected to the attachment 19 by a pin l id
- the bucket link 15 is connected to the attachment 19 by a pin 15b.
- the bucket link 15 is disposed outside the lift arm 11. As shown in FIG. 8, the bucket link 15 is offset with respect to the lift arm 11. The bucket link 15 is disposed at a position that does not overlap the lift arm 11 in the vertical direction (in plan view). Between the two plates of the intermediate link 13, the lift arm 11 is arranged at the center in the left-right direction, and between the two plates of the intermediate link 13, the bucket link 15 is arranged outside the lift arm 11. Yes. Thereby, it is possible to avoid interference between the lift arm 11 and the bucket link 15 when the packet 18 is moved up and down and swings.
- the stopper l ie can be easily configured and the durability of the stopper l ie can be improved.
- Fig. 11 is a diagram showing the stroke setting of the bucket cylinder
- Fig. 11 (a) is a diagram showing the maximum stroke state of the bucket cylinder
- Fig. 11 (b) is a diagram showing the excessive rotation state of the packet. .
- the bucket cylinder 14 When the lift arm 11 is rotated downward, the bucket cylinder 14 is rotated downward as shown in Fig. 11 (a), with the claw 18b provided at the lower edge of the packet 18 directly below the pin id. This is to prevent the packet 18 from rotating toward the work vehicle side from the pin l id which is the rotation fulcrum of the packet 18. That is, the maximum stroke of the bucket cylinder 14 is set to a length La in which the claw 18b is directly below the pin id in a state where the lift arm 11 is lowered. To limit the stroke of the bucket cylinder 14, attach a stopper to the bucket cylinder 14, make the stopper mounted on the rod in the cylinder contact the cylinder in the maximum stroke state, and increase the stroke length La It can comprise so that it may not extend above.
- the bucket link 25 has a reverse U-shaped cross section at a portion not pivotally supported in a front view.
- two plates 25c ′ 25c extending downward are attached to the lower surface of the plate 25b arranged in the horizontal direction.
- the lift arm 11 is positioned between the plates extending downward.
- the strength of the bucket link 25 can be improved while avoiding interference with the lift arm 11.
- the cross-sectional area that contributes to rigidity can be increased while reducing the vertical width of the bucket link 25, the bucket link 25 can be made compact, and the degree of freedom in design of the link mechanism for packet oscillation is reduced. Can be improved.
