The operating state of the tractor-mounted breaker according to the present invention configured as described above will be described schematically.

1 to 5, at the rear of the tractor (not shown), the vertical finish plate 10, 11, the breaking house 20, the breaking long shaft 30 on which the breakthrough blade member 40 is built, After installing the breaker consisting of the crash breaking device 50 and the power transmission device 110, it is operated in a stony paddy field, a field, an orchard, etc. to perform a breakthrough operation.

In this way, when the tractor is driven forward, the breaker seated on the floor surface by the skids 2 on both sides moves in the direction of travel of the tractor, and the upper center of the front fixing plate 21 of the breakthrough house 20 The power of the tractor is transmitted to the crushing long shaft 30 by the power transmission device 110 provided in the vertical finish plate 11, and the breaker blade member 40 of the crushing long shaft 30 in a clockwise direction (in the direction of the arrow) By rotating the stone, the stone embedded in the floor is pulled up and crushed first.

Briefly explaining the operation of this, as in FIGS. 1 and 6, the power of the tractor is transmitted to the input shaft 112 of the gearbox 111 constituting the power transmission device 110, so that the front bevel gear 113 It is rotated, and the side bevel gear 114 that meshes with the front bevel gear 113 rotates, and the horizontal connection shaft 115 which has one end rotatably connected to the side bevel gear 114 rotates. The crushing long shaft 30 is rotated by the pulleys 122 and 123 and the belt 124 constituting the power transmission member 120 installed at the end of the shaft 115.

In this way, as the long crushing shaft 30 rotates in a clockwise direction, a plurality of crushing blade members 40 which are staggeredly fixed to the outer circumferential surface of the crushing long shaft 30 rotate at high speed, so that the crushing blade 45 The stone is first crushed by the crushing force and centrifugal force of the crushing blade 44 made of cemented carbide and is mixed with the soil and scattered in the axial direction, while in the inner area of the front fixing plate 21 and the rear rotating finish plate 22 The gap adjustment crushing member 60, the front bump crushing member 80, and the rear bump crushing member 90 constituting a plurality of bumping crushing devices 50 that are fastened and fixed are collided and crushed secondarily.

That is, the stone is crushed first by the crushing force and the centrifugal force of the crushing blade 44 of the crushing blade 45, mixed with the soil, and scattered clockwise, while the inside of the front fixing plate 21 and the rear rotating finish plate 22 The inclined induction crushing blade 64 of the gap adjusting crushing member 60 constituting a plurality of bumping crushing devices 50 fastened to the area, the square rod-shaped crushing blade 86 of the front bumping crushing member 80 and the rear It collides with the inclined crushing blade 96 and the vertical crushing blade 97 of the bumping crushing member 90 at high speed and crushed secondarily.

At this time, the first crushed stone collides with a plurality of inclined guiding crushing blades 64 constituting the gap-adjusting crushing member 60 and crushed, leading to the crushing long shaft 30 region along the inclined slope to the crushing long shaft 30 region. As a result, rolling down to the area of the blocking member 100 installed in the front of the front fixing plate 21 of the breakthrough house 20 is blocked (see FIG. 4).

As shown in Fig. 7 that is crushed in this way, the stone and soil are inclined induction crushing blade 64 fixed to the front control hammer plate 62, the front hammer plate 82 and the rear hammer plate 92, and a square bar type crushing blade. (86), while passing between the inclined crushing blade 96 and the vertical crushing blade 97 is supported by the hydraulic piston 144 and the hydraulic cylinder 142 of the rotating member 140 constituting the rotating means 130 , While hitting the inclined crushing blade 96 inside the rear rotating finish plate 22, whose rotation angle is adjusted by the fixed hinge 133 and the rotating hinge 134, is treated as a floor surface, and at the same time, the breakthrough house 20 It is processed by hitting the chain-type blocking member 100 installed in the front of the front fixing plate 21 of the.

On the other hand, as shown in Figs. 8a and 8b, the front control plate 21 is fastened and fixed to the inside of the front fixing plate 21 and the circular closure 54 so that the primary crushed stone collides and secondly crushes the gap control crushing member 60 constituting the 61) is the adjusting plate moving member 70, and the particle size of the stone to be crushed is controlled by adjusting the gap with the crushing blade 45 on the outer circumferential surface of the crushing long shaft 30.

Briefly explaining the operating state for this, the tightening force of the bolt 65 and the nut 66 constituting the gap adjustment crushing member 60 are sequentially released loosely, and then an adjustment nut fixed to the front fixing plate 21 ( The adjusting bolt 74 fastened to the screw hole 72a of 72) is rotated clockwise.

Then, as the adjusting bolt 74 is fastened to the screw hole 72a of the adjusting nut 72 and moved to the rear, the end of the adjusting bolt 74 pushes the front adjusting plate 61 to the rear. As the horizontal moving hole (61a) of (61) is moved to the end along the bolt (65), the front control plate (61) is the maximum distance between the crushing blade (45) on the outer circumference of the crushing long shaft (30). Becomes narrower (see Fig. 8a).

Thereafter, the tightening force of the bolt 65 and the nut 66 constituting the gap adjustment crushing member 60 is completely tightened, and then the crushing blade 45 on the outer circumferential surface of the crushing long shaft 30 by operating the tractor When the stone is crushed as a crushing force, the particles of the stone to be crushed remain 2~4mm (big sand).

In this state, as shown in FIG. 8B, the tightening force of the bolt 65 and the nut 66 constituting the gap adjustment crushing member 60 is sequentially released and then the adjustment nut 72 fixed to the front fixing plate 21 ) By rotating the adjustment bolt 74, which is fastened to the screw hole 72a, in a counterclockwise direction to release the force pushing the front adjustment plate 61 backward as the adjustment bolt 74, and then the front adjustment plate 61 ) When the operator pulls forward, the horizontal moving hole 61a moves forward along the bolt 65 to the end, so that the front control plate 61 moves to the crushing blade 45 on the outer circumference of the crushing long shaft 30 The gap of the is widened to the maximum.

Thereafter, the tightening force of the bolt 65 and the nut 66 constituting the gap adjustment crushing member 60 is completely tightened, and then the crushing blade 45 on the outer circumferential surface of the crushing long shaft 30 as a rotational force due to the operation of the tractor When the stone is crushed as a crushing force, the particle of the stone to be crushed is maintained at 30mm~50mm.

That is, the front and rear moving distance of the front control plate 61 is appropriately adjusted and used according to the working environment so that the operator moves along the bolt 65 as much as the length of the horizontal moving hole 61a.

The tractor-mounted breakthrough device according to the present invention described above is not limited to the above-described embodiment, and those of ordinary skill in the field to which the present invention belongs without departing from the gist of the present invention claimed in the following claims Anyone will say that there is a technical idea to the extent that various changes can be implemented.
