It also refers to unsolidified soft fine-grained or extra-fine-grained soil deposited in hydrostatic or slow-flowing water and formed by physicochemical and biological actions. In fact, sediment is a modern deposit. In addition, depending on the particle size, the sedimentary mud is either powdery or clayey. Although rarely seen, there are also fine sands and ultrafine sands. Among them, clay minerals in beach mud are mainly illite and montmorillonite, and freshwater mud is mainly illite and kaolinite. In addition, the organic matter content in the sediment may be 2 to 3% at most, and 10 to 12% may be contained in a large amount. It decreases with increasing depth.

Conventionally, for dredging of narrow rivers, it is common to use a sewage pump to extract the bottom mud as it is. Occasionally, plastic bags can be found in the mud deposits. If a plastic bag is sucked into the pipe of a sewage pump at the time of dredging, it may cause clogging. Further, in the conventional dredging work, it is difficult to adjust the position and angle of the suction pipe at the riverbed, and sludge extraction is really inconvenient. In addition, it is difficult to extract directly because it is a riverbed work due to the accumulated mud.

This can be applied to various operating environments. Since the second ripple tube 92 is fixed by the nut 97, the screw rod 96, the connection socket 95 and the support rod 98, it is difficult for the end of the second ripple tube 92 to hang down, which hinders the rotation of the water inlet tube 91.

1 also moves downward in conjunction with it. Since the stop ring 61 is pressed against the position limiting plate 83, the position limiting plate 83 also moves downward while moving the stop ring 61 downward. Further, the first ripple tube 82 is stretched downward in conjunction with the position limiting plate 83. As a result, the working distance of the dredging mechanism 8 and the adjusting mechanism 9 at the time of dredging is greatly increased. Further, since the position limiting plate 83 has entered the inside of the stop ring 61 at a certain distance, the position limiting plate 83 can be easily moved during the process of moving the position limiting plate 83 downward by the stop ring 61 (movement stroke). It does not come off from the stop ring 61.

, The first pulley 51 and the second pulley 53 are sequentially arranged from right to left. With this configuration, when the motor 41 is started, the first pulley 51 and the second pulley 53 rotate. The push mechanism and the stirring mechanism are rotated synchronously in conjunction with the second pulley 53. As a result, the accumulated mud can be sufficiently agitated, and therefore the mud accumulated on the river bottom can be agitated, which can contribute to the subsequent dredging operation.

To move the stop ring 61 downward in conjunction with the downward movement of the stirring shaft 71. Here, since the stop ring 61 is pressed against the position limiting plate 83, the position limiting plate 83 is also moved down while the stop ring 61 is moved down. As a result, the first ripple tube 82 is extended downward in conjunction with the position limiting plate 83. Therefore, the dredging working distance of the dredging mechanism 8 and the adjusting mechanism 9 is increased. That is, the suction depth of the accumulated mud can be changed. This makes it convenient to use this device. Further, since the second ripple tube 92 has flexibility,
The angle of the water pipe 91 can be changed at a constant angle by the rotation of the column 93 and the connection rod 94 and the rotation between the connection socket 95 and the support rod 98. With such an operation design, if the plastic bag blocks the water inlet pipe 91 during dredging, the impact force of the water flow pushes the push rod 102 into the water inlet pipe 91, and the hook mechanism 104 pushes the plastic bag into the plastic bag. Is blocked in the space on the left side of the fixing rod 101 in the water inlet pipe 91, and one part of the plastic bag is hooked by the specific configuration of the hook mechanism 104. Therefore, the plastic bag cannot enter the water inlet pipe 91 through the gap between the hook mechanism 104 and the water pipe 91, but the accumulated mud is sucked through the gap between the hook mechanism 104 and the side wall of the water pipe 91. On the other hand, when the dredging is finished, take out this device and
The impact force of the water flow disappears inside the water inlet pipe 91, the push rod 102 is moved to the outside of the water inlet pipe 91 by the elastic force of the return spring 103, and the plastic bag is further pushed out. Therefore, such a configuration prevents the plastic bag from blocking the water inlet pipe 91. Further, since the adjusting mechanism 9 capable of adjusting the orientation angle during the dredging work is provided, it can be applied to the sedimented mud dredging under various conditions. Further, since the blockage prevention mechanism 10 is provided, the control mechanism 9 is not blocked by the waste plastic bag. also,
Since a stirring mechanism is provided to stir the accumulated mud, it can contribute to the subsequent dredging work. moreover,
Since the position limiting configuration 6 is provided, the dredging mechanism 8 can be moved in the vertical direction in synchronization with the stirring mechanism, and the stirring and dredging work can be performed regardless of the depth of the river channel.

FIGS. 1 to 6 show a river channel dredging device with a blockage prevention mechanism. It includes a plastic housing 1 installed symmetrically and a fixing plate 2 connected between both plastic housings 1.
The fixed plate 2 is provided with a variable vertically long dredging mechanism 8. The dredging mechanism 8 penetrates the upper end of the fixing plate 2 and extends to the lower side of the fixing plate 2. The dredging mechanism 8 includes a connecting pipe 81 fixedly installed at the upper end of the fixing plate 2, and a first ripple pipe 82 connected to the lower end of the connecting pipe 81 and penetrating the bottom end of the fixing plate 2. The first ripple tube 82 can exhibit the expansion / contraction function. A position limiting plate 83 is fixedly installed at the outer end of the first ripple tube 82 near the lower side. When the stirring mechanism is moved down by the push mechanism, the position limiting configuration is also moved down. The position limiting plate 83 is moved downward in conjunction with the position limiting configuration. Thereby, the first ripple tube 82 is stretched downward. In this way, the dredging mechanism 8 and the adjusting mechanism 9 can be moved down as the stirring mechanism is moved down. With this configuration, the dredging of the accumulated mud can be performed well.

Below the dredging mechanism 8, an adjustment mechanism 9 that can automatically adjust the dredging angle according to changes in the external environment.

A water pipe 91 fixedly installed at one end opposite to the position limiting plate 83 of the second ripple pipe 92, a column 93 fixedly installed on the outer wall of the water pipe 91, and fixed to the bottom end of the position limiting plate 83. The connection rod 94 to be installed, the support rod 98 fixedly installed at the right end of the water pipe 91, the screw rod 96 connected to the upper end of the position limiting plate 83 by the nut 97, and the screw rod 96 fixedly installed at the lower end of the screw rod 96. Includes connection socket 95. Here, the column 93 and the connecting rod 94 are rotatably connected. The support rod 98 and the connection socket 95 are rotatably connected. The second ripple tube 92 and the first ripple tube 82 communicate with each other. The water pipe 91 is a column 93
It is possible to rotate around the rotation point between the water pipe and the connection rod 94, that is, the angle of the water inlet pipe 91 can be rotated and adjusted. This can be applied to various operating environments. Since the second ripple tube 92 is fixed by the nut 97, the screw rod 96, the connection socket 95 and the support rod 98, it is difficult for the end of the second ripple tube 92 to hang down, which hinders the rotation of the water inlet tube 91. There is no.

An obstruction prevention mechanism 10 for preventing obstruction of the adjustment mechanism 9 due to a mixture in the sediment is provided on one side of the adjustment mechanism 9 on the opposite side of the dredging mechanism 8. The blockage prevention mechanism 10 includes a fixed rod 101 fixedly installed on the inner wall of the water inlet pipe 91, a push rod 102 slidably connected to the central portion of the fixed rod 101, and a plurality of fixed rods 102 fixedly installed on the outer wall of the push rod 102. Including the hook mechanism 104 of. A return spring 103 is fixedly installed at the left end of the fixed rod 101. The left end of the return spring 103 is in contact with the hook mechanism 104. 1. The return spring 103 is located on the outside of the push rod 102 1. Each hook mechanism 104 has a push rod 10
2 contains a plurality of cones arranged in a circumferential shape. When the inconvenience of the plastic bag blocking the water inlet pipe 91 occurs, the plastic bag pushes the push rod 102 into the water inlet pipe 91 by the slash force of the water flow. Moreover, the hook mechanism 104 blocks the plastic bag in the space on the left side of the fixing rod 101 in the water inlet pipe 91. also,
Depending on the specific configuration of the hook mechanism 104, one part of the plastic bag is hooked. Therefore, the plastic bag has the water pipe 91 through the gap between the hook mechanism 104 and the water pipe 91.
Although it cannot occur inside, the deposited mud is sucked in through the gap between the hook mechanism 104 and the side wall of the water pipe 91. On the other hand, when the dredging is completed, the apparatus is taken out, the impact force of the water flow disappears inside the water inlet pipe 91, the push rod 102 is moved to the outside of the water inlet pipe 91 by the elastic force of the return spring 103, and further, the plastic bag. Stick out. As a result, the plastic bag cannot block the water pipe 91.

The stirring mechanism includes a stirring shaft 71 fixedly installed at the output end of the linear motor 76, and a plurality of stirring claws 72 fixedly installed at the bottom end of the stirring shaft 71 and uniformly arranged. When stirring the accumulated mud, the accumulated mud can be further sufficiently agitated by the stirring claw 72, and the obstruction due to the accumulated mud is reduced.

A position limiting configuration 6 for driving the dredging mechanism 8 and the stirring mechanism to move in the vertical direction in synchronization is provided on the outside of the stirring mechanism. The position limiting configuration 6 includes a stop ring 61 provided on the outside of the stirring shaft 71, and at least two positioning rods 62 fixedly installed between the stop ring 61 and the stirring shaft 71. The left end of the position limiting plate 83 extends into the inside of the retaining ring 61,
It is in contact with the bottom end of the stop ring 61. When the stirring shaft 71 moves downward, the stop ring 6
1 also moves downward in conjunction with it. Since the stop ring 61 is pressed against the position limiting plate 83, the position limiting plate 83 also moves downward while moving the stop ring 61 downward. Further, the first ripple tube 82 is stretched downward in conjunction with the position limiting plate 83. As a result, the working distance of the dredging mechanism 8 and the adjusting mechanism 9 at the time of dredging is greatly increased. Further, since the position limiting plate 83 has entered the inside of the stop ring 61 at a certain distance, the position limiting plate 83 can be easily moved during the process of moving the position limiting plate 83 downward by the stop ring 61 (movement stroke). It does not come off from the stop ring 61.

Further, the fixing plate 2 is provided with a push mechanism for fixing the stirring mechanism to a limited position and driving the stirring mechanism to move in the vertical direction. The push mechanism includes a fixed cylinder 31 fixedly installed at the upper end of the second pulley 53, a mounting plate 75 connected and fixed to the upper end of the cylinder 31, and a linear motor 76 fixedly installed at the lower end of the mounting plate 75. .. The stirring mechanism is rotated by the transmission mechanism, and the stirring depth of the accumulated mud can be adjusted by the water level. The linear motor 76 may be started and driven so as to move the stirring shaft 71 downward to an appropriate position by the output end thereof. Further, the mounting plate 75 and the fixing cylinder 31 are connected by a plurality of screws and can be easily disassembled.

A transmission mechanism for rotating and driving the push mechanism is provided on the fixed plate 2. The transmission mechanism includes a fixed holder 42 fixedly installed at the upper end of the fixed plate 2, a motor 41 fixedly installed at the upper end of the fixed holder 42, and a first pulley 51 rotatably connected to the upper end of the fixed plate 2. And the second
The pulley 53, the belt 52 sewn on the outer ends of the first pulley 51 and the second pulley 53, and
including. The output end of the motor 41 penetrates the upper end of the fixed holder 42 and is fixed to the first pulley 51. A connecting pipe 81 and a fixed holder 42 between the first pulley 51 and the second pulley 53.
, The first pulley 51 and the second pulley 53 are sequentially arranged from right to left. With this configuration, when the motor 41 is started, the first pulley 51 and the second pulley 53 rotate. The push mechanism and the stirring mechanism are rotated synchronously in conjunction with the second pulley 53. As a result, the accumulated mud can be sufficiently agitated, and therefore the mud accumulated on the river bottom can be agitated, which can contribute to the subsequent dredging operation.

The operating principle of the apparatus according to the present invention will be described. First, the fixing plate 2 is assembled on the ship. Next, the motor 41 and the linear motor 76 are electrically connected to the power source on the ship. Motor 4
1 is activated, and the first pulley 51 and the second pulley 53 are rotated. By the second pulley 53
The fixed cylinder 31, the linear motor 76 and the stirring shaft 71 are rotated. In conjunction with the stirring shaft 71,
The stirring claw 72 rotates and is further inserted into the mud to sufficiently stir the accumulated mud. In this way, the sediment on the riverbed is agitated and scraped up. Further, in order to change the depth of insertion of the stirring shaft 71 into the accumulated mud, the linear motor 76 is started, and the stirring shaft 71 is directed downward in conjunction with the extension of the output end of the linear motor 76. To move the stop ring 61 downward in conjunction with the downward movement of the stirring shaft 71. Here, since the stop ring 61 is pressed against the position limiting plate 83, the position limiting plate 83 is also moved down while the stop ring 61 is moved down. As a result, the first ripple tube 82 is extended downward in conjunction with the position limiting plate 83. Therefore, the dredging working distance of the dredging mechanism 8 and the adjusting mechanism 9 is increased. That is, the suction depth of the accumulated mud can be changed. This makes it convenient to use this device. Further, since the second ripple tube 92 has flexibility,
The angle of the water pipe 91 can be changed at a constant angle by the rotation of the column 93 and the connection rod 94 and the rotation between the connection socket 95 and the support rod 98. With such an operation design, if the plastic bag blocks the water inlet pipe 91 during dredging, the impact force of the water flow pushes the push rod 102 into the water inlet pipe 91, and the hook mechanism 104 pushes the plastic bag into the plastic bag. Is blocked in the space on the left side of the fixing rod 101 in the water inlet pipe 91, and one part of the plastic bag is hooked by the specific configuration of the hook mechanism 104. Therefore, the plastic bag cannot enter the water inlet pipe 91 through the gap between the hook mechanism 104 and the water pipe 91, but the accumulated mud is sucked through the gap between the hook mechanism 104 and the side wall of the water pipe 91. On the other hand, when the dredging is finished, take out this device and
The impact force of the water flow disappears inside the water inlet pipe 91, the push rod 102 is moved to the outside of the water inlet pipe 91 by the elastic force of the return spring 103, and the plastic bag is further pushed out. Therefore, such a configuration prevents the plastic bag from blocking the water inlet pipe 91. Further, since the adjusting mechanism 9 capable of adjusting the orientation angle during the dredging work is provided, it can be applied to the sedimented mud dredging under various conditions. Further, since the blockage prevention mechanism 10 is provided, the control mechanism 9 is not blocked by the waste plastic bag. also,
Since a stirring mechanism is provided to stir the accumulated mud, it can contribute to the subsequent dredging work. moreover,
Since the position limiting configuration 6 is provided, the dredging mechanism 8 can be moved in the vertical direction in synchronization with the stirring mechanism, and the stirring and dredging work can be performed regardless of the depth of the river channel.
