The fixed frame protrusion 110 is to prevent rotation of the main frame 200 by being caught by the main frame protrusion 210 when the main frame 200 is rotated by a predetermined angle with respect to the fixed frame 100.

Referring to FIG. 1, a support rod 231 may be attached to one end of the main frame 200. As the support rod 231 is fitted to the holder 233 so that the fixing frame 100 is positioned above the ground, the fixing frame 100 may be easily fixed to the tractor (not shown).

1 and 2, the blade connecting frame 300 is connected to the other side of the main frame 200. The blade connecting frame 300 may be formed in a plate shape. Hereinafter, the connection structure of the main frame 200 and the blade connecting frame 300 will be described.

Referring to FIG. 2, the vertical hinge shaft 320 protrudes in the vertical direction on an upper surface of the blade connecting frame 300. The vertical hinge shaft 320 has a first vertical hinge shaft 320-1 having a lower end integrally fixed to an upper surface of the connecting frame 300, and a second vertical hinge connected to an upper end of the first vertical hinge shaft 320-1 . It may include a hinge shaft (320-2). The second vertical hinge shaft 320-2 may have a smaller diameter than the first vertical hinge shaft 320-1 .

Referring to FIG. 2, the rotating plate 220 is rotatably fitted to the second vertical hinge shaft 320-2. On the other hand, the separation preventing jaw 330 is formed on the second vertical hinge shaft 320-2 to prevent the rotating plate 220 from being separated upward.

2, the other side of the main frame 200 is fixedly connected to the rotating plate 220. The main frame 200 may be fixedly connected to the rotating plate 220 by welding the lower portion of the other peripheral surface to the rotating plate 220. Accordingly, the blade connecting frame 300 can rotate in the horizontal direction with respect to the main frame 200.

1 and 3, the blade 400 is connected to the blade connecting frame 300. The blade 400 is connected to the blade connecting frame 300 to be rotatable in the direction of the tractor (not shown) or in the opposite direction of the tractor (not shown). Hereinafter, the connection structure of the blade connecting frame 300 and the blade 400 will be described.

Referring to FIG. 3, the blade 400 may include an upper plate 410 and a lower plate 420 connected downward to the upper plate 410. The coupling plate 410P is attached to the upper plate 410 of the blade 400, and the outer rotation support cylinder 430 is integrally formed on the coupling plate 410P.

3, the blade connecting frame 300 is formed integrally with the inner rotary support cylinder (310). The rotary rod R is fitted to the inner rotary support cylinder 310 and the outer rotary support cylinder 430 while the inner rotary support cylinder 310 and the outer rotary support cylinder 430 are positioned on the same line. Accordingly, the blade 400 may rotate in the direction of the tractor (not shown) or the opposite direction of the tractor (not shown).

1 and 4, the restoring means 500 is connected to the blade connecting frame 300 and the blade 400, and the restoring means 500 includes a spring support rod 510 and a restoring spring 520.

Referring to Figure 4 the spring support rod 510 is fixed to the upper plate of the lower blade 400. The upper side of the spring support bar 510 is protruded upward through the blade connecting frame 300.

Therefore, when the blade 400 rotates in the direction of the tractor (not shown) or the opposite direction of the tractor (not shown), the blade 400 returns to its original position by the elastic restoring force of the restoring spring 520. If there is an obstacle on the road surface during snow removal, the lower plate 420 of the blade 400 is caught by the obstacle. In this case, when the blade 400 does not rotate in the opposite direction to the tractor (not shown), the impact caused by the obstacle is transmitted to the tractor (not shown) without being alleviated, thereby causing damage to the tractor (not shown). This may occur. In this embodiment, the blade 400 rotates in the opposite direction to the tractor (not shown) in this case, and thus, the impact caused by the obstacle is alleviated. On the other hand, when the lower plate 420 of the blade 400 exceeds the obstacle, the blade 400 is rotated in the direction of the blade connecting frame 300 by the elastic restoring force of the restoring spring 520 to return to the original position.

Referring to FIG. 5, the actuator 600 is connected to the fixed frame 100 and the blade 400. Actuator 600 may include a cylinder tube 510 and a piston rod 620. The actuator 600 may be connected to the blade 400 so that the cylinder tube 510 side may be rotatable in the vertical and horizontal directions to the fixed frame 100 and the piston rod 620 may be rotatable in the vertical and horizontal directions. have. As the piston rod 620 slides in a linear direction with respect to the cylinder tube 510, the blade 400 can rotate about the vertical hinge axis 320 .

According to an embodiment of the present invention, since the main frame 200 is fitted to the fixed frame 100 so that the main frame 200 can rotate in the circumferential direction of the main frame 200, the main frame 200 is fixed to the main frame 200 according to the left and right tilting states of the road surface. It rotates with respect to (100), the end of the lower plate 420 of the blade 400 is always in contact with the road surface. Accordingly, there is an advantage that can effectively perform the ground leveling and snow removal work.

According to an embodiment of the present invention, when there is an obstacle on the road surface during operation, the blade 400 contacts the obstacle and rotates in the opposite direction to the tractor (not shown). Accordingly, the impact force due to the contact with the obstacle is alleviated, the impact applied to the tractor (not shown) is reduced, there is an advantage that the risk of damage to the tractor (not shown) is reduced.
