Abstract

PURPOSE:To freely change the angle of a blade to a working machine by using a system in which left- and right-handed blade fitting braces are fixed to a bracket sliding on a blade fitting frame, and the position of the bracket is altered on either side. CONSTITUTION:The basal ends of braces 10 and 10' for fitting a blade 5 are fixed to a bracket 13 sliding on the rail 14 of a blade fitting frame 3 by means of a pin. When a bracket moving cylinder 15 is actuated, the bracket 13 moves on the rail 14, and the blade 5 turns left and right at a free coupler 11 as the center and takes a desired angle in relation to a working machine 1.

経済であるなどの欠点を有していた。Conventionally, there are obstacles such as other fixed equipment around the processing of lump and granular mineral materials in mines, the movement of lump and granular raw materials or products in various parts of factories, and the movement of lump and granular cargo in ship tanks. Mini wheel loaders and two-way dozers have been used to carry out all transportation work within a limited range. However, when these vehicles are used, for example, in indoor raw material storage areas such as factories with limited space, there are cases where bulk and granular raw materials are pushed into the opening of a hopper provided on the work surface, or when there is a small space. When collecting grain, etc. in a casket from the area of action of the clamshell packet of a unloading crane, i.e. the center of the hatch, it is necessary to push the object to be processed from around the hopper or hatch, but conventional work vehicles cannot do this. The blades are fixed perpendicular to the direction of travel of the vehicle and only have a push/pull function, so they must frequently change direction, go forward or backward, etc. Lever operations for switching and shocks when switching between forward and backward directions increased operator fatigue. In addition, the repetition of forward and backward movement is extremely wasteful as half of the movement is in the reverse direction, resulting in extremely high fuel consumption for the same amount of cargo handling, and in addition, the required processing time is also long, resulting in damage to the vehicle. It also had serious drawbacks, such as being extremely inefficient and uneconomical.

The blade (5) can be moved up and down, and the blade (5) can be tilted forward and backward three-dimensionally by fully extending and retracting the cylinder (8) for varying the longitudinal angle of the blade. In addition to these angle actions, in the work vehicle of the present invention, if the left and right horizontal angle angle cylinders are slid on the slide rail (14) in the front and back directions by hydraulic means, the vehicle progresses. The angle made by the blade (5) with respect to the direction can be varied in the horizontal plane.

Due to this effect, objects can be partially placed into the hopper one after another without changing the traveling direction of the dozer. That is, in the past, as shown in Fig. 4, for example, in the case of cargo handling on a ship, the purpose could not be achieved unless the dozer was operated at right angles toward the center of the hold (81) @ hatch (82) and repeatedly moved back and forth. Hold partition (8
8) Because of this, it was very difficult to perform the treatment with this dozer as shown in the work mode (84) shown in the figure. However, when using the horizontal angle two-way dozer of the present invention, the two-way blade is in the pushing state while the two-way blade is in the ship wall or Hold partition (33
], the work pattern (35) shown in Fig. 5 is obtained.
Objects can be easily and almost completely concentrated in the center of the no-tsuchi.

This brings about many effects such as being able to safely and efficiently select the form. Also, in terms of manufacturing, compared to conventional two-way dozers, it has the advantage of making it easier to manufacture special parts and reducing costs.
