Description

Wheeled sludge dredger with steering device {control direction device have a wheel type sludge dredge}

The present invention relates to a wheel-type sludge dredger with a steering device, and in particular, to enable the dredger to move at a low speed while maintaining a constant speed, so that the sludge stacked on the floor can be collected evenly and the dredger is stopped. The present invention relates to a wheeled sludge dredger having a steering device for improving the workability and mobility by allowing the user to turn 360 degrees.

In general, sludge on the lake or shore is washed by rainwater during rainy weather or by artificial throwing, and sludge is accumulated on the bottom of the lake or shore by artificial throwing. This sludge accelerates water pollution and damages the surrounding landscape. Will be broken.

Therefore, in order to improve verticality by increasing the collection rate of sludge stacked on the bottom surface, the dredger can move at low speed while maintaining a constant speed so that the sludge stacked on the bottom can be collected evenly. In addition, the dredger should be able to turn 360 degrees while it is stationary to facilitate movement and improve workability.

As described above, since the collection rate of sludge is improved according to the moving speed and the turning capability of the dredger, the technical trends of the dredger have been recently improved to improve the functionality of the dredger.

Meanwhile, in the related art, referring to FIG. 9, a registration number 20-301737 (name: sludge collection device) registered and filed by the same person, first, a hull 2 having buoyancy is formed, and the hull 2 has a tip. The boom 44 is installed so that it can be raised or lowered, the front end portion of the boom 44 is provided with a collecting device 4 for collecting sludge stacked on the bottom surface of the water.

And a control unit 26 for adjusting the operation of the boom 44 and the collecting device 4 is installed in the middle portion of the hull (2), the power received from the engine unit not shown in the rear of the hull (2) Screws for generating propulsion and keys for adjusting the direction of movement are provided.

The scoops and tall are usually installed and applied to the hull.

Referring to the operation of the conventional technology configured as described above is as follows.

First, the control unit 26 is operated to lower the boom 44 to position the collection device 4 on the bottom of the water. When the collection device 4 is operated, the sludge accumulated on the bottom of the water moves to the outside. Done.

In the above state, the dredger is moved while the screw is rotated by the power provided from the engine unit, which is not shown. In this case, when the dredger is to be moved, the key is adjusted by turning the key, which is not shown. Adjust it.

Since the prior art described above is moved by a rotating scruw, the dredger is difficult to move at a low speed while maintaining a constant speed according to the sleep situation, and thus, the sludge stacked on the floor cannot be collected evenly. There is this.

Another problem is that dredgers moved by KEI have a large turning radius, which makes it difficult to turn dredgers in narrow places, resulting in poor workability and mobility.

The present invention aims to allow the dredger to move at low speed while maintaining a constant speed, so that the sludge stacked on the floor can be collected evenly.

Another object is to allow the dredger to rotate 360 degrees while stationary, thereby improving workability and mobility.

Accordingly, the hydraulic motors a and b 22 and 24 simultaneously move in the forward direction and rotate the wheels 26 forward and move along the bottom surface of the water, which causes the hull 4 (see FIG. 6) to rotate the wheels 26. ) Will move forward in proportion to the distance traveled along the underwater surface.

Unlike the above, when the control part 8 (refer to FIG. 3) is operated again to operate the directional control valves a, b (16, 18) in order to reverse the hull 4, the flow direction of the oil is changed so that the hydraulic motor The a, b (22, 24) is operated in the reverse direction to reverse the wheel 26.

Thus, the hull 4 (see FIG. 6) will retract together in proportion to the distance the wheels 26 have traveled along the underwater surface.

Unlike the above, when turning the hull 4, the control part 8 (see Fig. 3) is operated to operate the direction control valve c56 (in this case, the direction control valve d 58 is selectively turned on). When the direction control valve d 58 is kept off, the oil supplied from the oil pump 14 passes through the direction control valve c 56 and reaches the adjustment cylinder a 46 so that the rod ( 50) is advanced.

As a result, the rod 50 pushes the lever 42 to rotate the rotary shaft 34 in one direction, as shown in FIG. 7, so that the column 28 and the hydraulic motor a 22 (see FIG. 5), The wheels 26 (see FIG. 7) and the like are simultaneously moved, wherein the wheels 26 are positioned on a line parallel to the side wall surface of the hull 4 and inclined at a predetermined angle.

Therefore, by operating the hydraulic motor a 22, the wheel 26 rotates at a predetermined angle and rotates along the bottom of the water while turning the hull 4 (see FIG. 7), and at the same time, the idle state The hydraulic motor b 24 (see FIG. 3) causes the wheel 26 to move idling along the swinging hull 4 (see FIG. 7).

At this time, if the wheel 26 on the hydraulic motor a (22) side is continuously rolling, and the wheel (26) located on the hydraulic motor b (24) is stopped and in the current position, the hull (4) at the current position It will rotate 360 degrees.

When the control part 8 (refer FIG. 3) is operated in the above-mentioned state, the direction control valve c56 is operated again, and it returns to the original position, and the rod 50 is lever 42 (refer FIG. 7). By rotating the rotary shaft 34 to rotate the rotary shaft 34, the guide 30, the hydraulic motor a 22 (see FIG. 5), the wheel 26 (see FIG. 7) and the like are returned to their original positions.

When the hydraulic motors a, b (22, 24) (see Fig. 3) are operated as described above in the above state, the wheels 26 move along the underwater surface to move the hull 4 (see Fig. 7). Will be advanced or reversed.

In this state, the control unit 8 is operated to operate the direction control valve a 16 so that oil is supplied to the hydraulic motors a, c and 22 and 62, and at the same time, the direction control valve b 18 is The off state is maintained so that the hydraulic motors b and d (24, 64) can idle.

Therefore, by operating hydraulic motors a and c (22 and 62), the wheels 26 and 60 rotate in a state inclined at a predetermined angle and roll along the bottom of the water while turning the hull 4 (see Fig. 4). At the same time, the hydraulic motors b, d (24, 64) (see Fig. 8) in the idle state move the wheels 26, 60 idling along the swinging hull 4 (see Fig. 4).

At this time, the wheels 26, 60 on the hydraulic motors a, c (22, 62) continue to roll, and the wheels 26, 60 on the hydraulic motors b, d (24, 64) stop and stop at the current position. When in the hull, the hull rotates 360 degrees.

Unlike the above, when the control part 8 (refer to FIG. 8) is operated and the directional control valve c 56 is operated again to return to the original position, the rods 50 and 70 are lever 42 (refer to FIG. 4). ) Rotates the rotary shaft 34 to reverse, and the guide 30 and the hydraulic motors a, c (22, 62) (see Fig. 8) and the wheels 26, 60, etc. are returned to their original positions.

When the hydraulic motors a, b, c, d (22, 24, 62, 64) are operated as described above in the above state, the wheels 26, 60 move forward together with the hull 4 (see Fig. 4). Or reverse.
