As shown in FIGS. 1 and 2, a drum cover for a breaker according to the present invention is installed in the breaker 100.

The breaker 100 basically comprises a base frame 110, an input chamber 120 provided on the upper portion of the base frame 110, and an input conveyor 130 constituting the bottom surface of the input chamber 120 .

At this time, the input chamber 120 is provided at a predetermined height from the lower end of the base frame 110 in order to secure a sufficient installation space for the input conveyor 130.

The rear end of the closing conveyor 130 is disposed at a lower side of the closing chamber 120 in a state where the front end of the closing conveyor 130 is positioned above the center of the drum 210, So as to be upwardly inclined.

In this case, the input conveyor 130 is disposed in an inclined state so that the garbage bag, that is, the digging bag, which is carried on the input conveyor 130, is not back-drafted.

In this case, the back draft refers to a phenomenon in which the rotating drum and the inserted pebble stick are pushed backward. When the tip of the loaded conveyor 130 is positioned above the center of the drum 210 as in the present invention, This is because the drums (210), which receive the force of descent, can easily and smoothly draw the sticks.

On the other hand, in the prior art, since the feed conveyor is horizontally installed, the pebble stalks inserted by the rotating drum are pushed back, and the efficiency of feeding is lowered, thereby significantly lowering the breaking efficiency. In the present invention, As such, it is designed to completely eliminate such phenomena.

The drum 210 is installed on the input unit 200 and is rotated in a counterclockwise direction by a driving source not shown. A drum cover 300 is installed on the drum 210, So that the stick does not protrude but smoothly rotates along the drum 210.

Particularly, the drum cover 300 according to the present invention is characterized in that the drum cover 300 according to the present invention is formed as a floating type having a kind of Snake movement structure unlike the conventional fixed type.

1 and 3 to 5, the drum cover 300 has a unique shape according to the present invention. The drum cover 300 includes a side plate 310, which includes a base frame 110, Respectively.

At this time, the side plate 310 is a basic member constituting the outer shape of the drum cover 300, and is formed with an arc, which is formed in accordance with the curvature of the drum 210.

The hinge shaft 320 is fixed to both sides of the lower end of the side plate 310 by a bracket B. The hinge shaft 320 is fixed to the hinge shaft 320 fixed to the base frame 110, And is rotatably connected to the fixed bearing 330 to rotate the drum cover 300 as a whole.

2B, an extension rod 302 is fitted and fixed on a lower end of the drum cover 300, that is, a hinge shaft 320 fixed to the bracket B, The tension spring 308 is inserted into the operation rod DR and the tension spring 308 is inserted into the tension spring 308 The lower end is supported by a spring base 304 and the extension rod 302 passes through the spring base 304 and is fastened by a fixing nut 306 at its bottom surface.

The upper end of the extension rod 302 is fixed to the hinge shaft 320 so that when the drum cover 300 is opened and closed, the extension rod 302 can have rotational fluidity, So that the rotation operation of the cover 300 is not affected.

A fixing rod FR is fixed to one side of the support base 112. The fixing rod FR is fixed to the base frame 110 via a pin C via a cylinder CY.

Accordingly, the force to be applied when the drum cover 300 is opened and closed can be adjusted through the adjustment of the tension spring 308, and the load applied to the hinge shaft 320 is normally dispersed to prevent excessive force from being applied. And the length of the fixing rod FR can be varied to adjust the fixing force of the pin P when necessary.

1 and 3, a fastener 340 is fixed to both sides or an end of an upper end of the side plate 310. The fastener 340 is fastened to the cylinder rod 352 of the cover opening / And the rear end of the cover opening / closing cylinder 350 is fixed to the fastening member 360 fixed on the base frame 110.

Therefore, the drum cover 300 can be opened and closed while being rotated about the hinge shaft 320 in accordance with the forward / backward movement of the cover opening / closing cylinder 350.

A side guide 370 is provided on both sides of the inside of the side plate 310 so as to prevent the peeling of the peeled sewing thread from being scattered. A forward upper guide 380 is provided on the upper side of the side plate 310, .

In addition, a plurality of flow plates 390 as shown in FIGS. 4 and 5 are connected to the inside of the drum cover 300 in a state entangled with each other through a flow hinge 392.

At this time, the foremost end is hinged to the rear end of the front upper guide 380, and the rearmost end is connected to a mounting hole (not shown) formed at the rear end of the side plate 310 H).

Accordingly, the flow plate 390 automatically adjusts the gap with the drum 210 in accordance with the load as the snake, that is, the snaking motion, moves according to the change of the load.

As a result, even when a large-sized fishing rod enters, it automatically flows and reduces the load, so that it is possible to smoothly break the equipment without any trouble, and the breaking efficiency is increased accordingly.

In addition, a plurality of fixed blades 400 are provided on the inner surface of the flow plate 390 at intervals in the longitudinal direction.

The fixed blade 400 is provided to intersect with the breaking blade 220 (see FIG. 2) provided on the drum 210 so as to intersect with each other, thereby further promoting breakage. Particularly, the string, So as not to be wound on the axial flow such as the drum axis.

Therefore, if the drum cover 300 according to the present invention is provided, it is possible to prevent the wrapping of the strings by the string flow, thereby improving the working efficiency and increasing the throughput and processing efficiency.

In addition, the fixed blade 400 may have various shapes, such as those illustrated in FIGS. 6, 7, and 8, and may be used alone or in combination. Show.

For example, in the case of FIG. 6, a multi-stage triangular knife 410 is arranged in the form of a multi-stage triangle 410 in the form of a scallop 412, a middle knife 414 and a large knife 416, So as to facilitate the initial entry of the fish ball.

At this time, the multi-stage triangular knife 410 of the multi-stage triangle is a single type formed independently at the central portion of the blade base BA.

In another example, the case of FIG. 7 is a multi-stage triangle and a triangle composite type in which at least two single triangular knives 420 spaced apart from the multi-stage triangle knob 410 are fixed on the blade base BA, ), It is designed to be staggered without overlapping each other.

As another example, FIG. 8 shows an example in which two independent triangular knives 420 are arranged in parallel.

The reason why the fixed blade 400 is arranged as described above is that the blade and the blades are staggered with a slight gap so that a kind of scissoring function can be realized. As a result, So as to eliminate the winding-up problem.

Since the drum cover 300 according to the present invention absorbs the shock while absorbing the snake flow according to the amount of load, the overflow problem can be easily solved, and the string flow can be easily cut to a short length through the staggered arrangement of the blade. And has a unique effect of sweeping away.

Therefore, the processing efficiency is enhanced, the work efficiency is improved, and the cost is saved.
