定に保つことができるものである。 Conventionally, as shown in Figures 1 and 2, a ski device that is attached to the back of the blade of a work vehicle such as an angle plow for snow removal or a cold dozer to maintain a constant excavation depth of the blade during work has been used. A pair of pin support pieces 4 (only one is shown in the figure) is attached to the left and right sides of the rear surface of 2, and each pin support piece 4 supports a pin 6 that extends in a substantially vertical direction. One end of each bracket 8 is pivotally supported so as to be able to swing, and a cylinder 10 extending vertically is fixed to the other end of each bracket 8, and the height can be adjusted vertically within the cylinder by rotating a handle 12. A shaft 14 whose position is adjustable is provided, and the longitudinal intermediate portion of a long plate-shaped ski 16 is pivoted at the lower end of the shaft so as to be able to swing in a vertical plane. The lever ski 16 can be pivoted about the pin 6 as shown by the two-dot chain line in Figure 1, or the bracket 8' can be mounted directly on the back of the blade as shown in Figure 3.
is fixed, and a disk-shaped ski 16 is provided at the lower end of a shaft whose height can be adjusted up and down by rotating a handle 12 in the cylindrical body 10 at the tip of the bracket so as to be able to swing in a vertical plane. There is one that is pivoted almost at the center of '. These ski devices are capable of keeping the excavation depth of the blade 2 constant by sliding the skis 16, 16' on the snow surface or the ground during operation.

湾曲面に形成してある。 FIGS. 4 and 5 show an embodiment of the present invention, which, like the conventional device described above, has pin support pieces 4a spaced apart vertically on both sides of the back surface of the blade 2. 1 and 4a 2 (only the pin support piece on one side is shown in the figure), and a pin 6a extending approximately perpendicular to each pin support piece 4a 1 and 4a 2 .
A ski support bracket 8 is pivoted at one end around each pin 6a so as to be able to swing in a substantially horizontal plane, and the other end of each bracket 8 is A cylindrical body 10 extending in the vertical direction is fixed, and a handle 1 is inserted into the cylindrical body 10.
A shaft 14 whose height can be adjusted by moving up and down by the rotation operation of 2 is provided, and at the lower end of the shaft 14 there is a ski 16a in the form of a long curved plate, at the longitudinal center of the ski 16a so as to be able to swing in a vertical plane. It is centrally supported.
However, in the device of this embodiment, the ski 1
When the ski 6a slides along the snow surface or the ground, etc., in order to prevent the bending force from acting directly on the shaft 14 and the cylindrical body 10 of the bracket in the front-rear direction (especially backward), as shown in the figure, the ski The tip of the pin 16a is connected to the lower end of a rotatable pin 6a firmly attached to the blade 2 with a pin 18, and the force of bending in the longitudinal direction (especially backward) is applied to the pin 6a.
It is characterized by being received in a. Also,
When the height position of the ski 16 is adjusted as shown by the two-dot chain line in FIG. The entire bottom surface of 16a is formed into a smooth curved surface projecting downward as shown in the figure.

させることによりピン６ａのガタ付を防止する。 FIG. 6 shows another embodiment of the present invention, which is substantially similar to the previous embodiment, but differs in the following points. That is, in this embodiment, the pin 6a is installed so that when the height position of the ski 16a is adjusted by rotating the handle 12, the height position of the tip of the ski 16a can also be adjusted at the same time.
The height position can be changed vertically with respect to the pin support pieces 4a 1 and 4a 2 . The height position of the pin 6a can be adjusted by selectively adjusting one of the plurality of pin holes 22 formed in the pin 6a in order to fix the stopper 20 that engages on the pin support piece 4a 1 to the upper end of the pin 6a. This is done by changing the position of the locking pin 24 inserted into. Note that by interposing the spacer 26 between the pin support piece 4a2 and the enlarged portion of the lower end of the pin 6a, the pin 6a is prevented from wobbling.
