Description

Technical Field

[0001] This utility model relates to the technical field of river dredging, and in particular to a water conservancy river dredging device. Background Technology

[0002] Silt is an unconsolidated, soft, fine-grained or extremely fine-grained soil formed by physicochemical and biochemical processes in still or slow-flowing water environments. It is a relatively recent sediment. Excessive silt at the bottom of riverbeds provides a breeding ground for various pathogens and parasites, leading to ecological deterioration and hindering the growth of other organisms in the river. Therefore, regular silt removal is necessary. Silt removal typically involves using a suction pump connected to a suction pipe extended to the riverbed to remove the silt. However, the riverbed is complex, with varying heights, which can prevent the suction pipe from effectively removing silt. Furthermore, silt may clump together at the bottom, resulting in low dredging efficiency.

[0003] Therefore, we propose a water conservancy river dredging device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a water conservancy river dredging device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A water conservancy river dredging device includes an installation rod and a suction pipe. The suction pipe is installed on the side wall of the installation rod. A receiving groove is formed on the upper end face of the installation rod. An extension rod is provided inside the receiving groove. A return spring is connected between the extension rod and the bottom surface of the inner cavity of the receiving groove. An installation plate is provided on the upper side of the extension rod. An adjustment mechanism is provided between the extension rod and the installation plate to adjust the two. A stirring rod is rotatably connected to the lower end of the installation rod. A protective cover is connected to the side wall of the installation plate outside the stirring rod.

[0007] Preferably, a guide groove is provided on the inner wall of the storage slot, and a guide block is connected to the side wall of the extension rod corresponding to the position of the guide groove, and the guide block extends into the guide groove to cooperate with it.

[0008] Preferably, the mounting plate is L-shaped and has multiple sets of mounting holes on its sidewalls, which are engaged with external mounting bolts.

[0009] Preferably, the adjustment mechanism includes an adjustment plate connected to the upper end of the extension rod. A set of longitudinally penetrating adjustment holes are provided on the side wall of the adjustment plate. A screw and a limiting rod are respectively provided in the set of adjustment holes, and the inner wall of the adjustment hole corresponding to the position of the screw is provided with a thread.

[0010] Preferably, a drive motor is installed in the inner wall of the mounting rod, the power output end of the drive motor is connected to the stirring rod, and a crushing tooth plate is connected to the side wall of the stirring rod.

[0011] Preferably, the protective cover is a mesh cover and is semi-circular in shape. A guide wheel is rotatably connected to the side wall of the protective cover, and a coil spring is provided at the rotatable connection between the guide wheel and the protective cover.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In use, this invention utilizes the combined action of a screw, adjusting rod, and adjusting hole to extend the lower suction structure of the device downwards to the bottom of the riverbed. This allows the suction pipe to contact the riverbed and perform silt suction. Simultaneously, a crushing toothed plate is rotatably connected to the lower end of the mounting rod, which stirs and breaks up the silt structure at the bottom of the riverbed. This allows the suction pipe to suction the silt more quickly and effectively, improving overall dredging efficiency. Furthermore, as the device moves and the riverbed level fluctuates, the stirring rod, crushing toothed plate, and protective cover can be adjusted to their appropriate heights by the return spring and guide wheel. This adapts to the riverbed environment, ensuring the suction pipe remains stably positioned at a suitable height above the riverbed, guaranteeing efficient silt suction. Attached Figure Description

[0023] Reference Figure 1-4 A water conservancy river dredging device includes an installation rod 1 and a suction pipe. The upper end of the suction pipe extends upward along the installation rod 1 and an extension rod 3, and is connected to an external suction pump for pumping silt to the upper side for processing. The suction pipe is installed on the side wall of the installation rod 1. A receiving groove 2 is provided on the upper surface of the installation rod 1. An extension rod 3 is provided inside the receiving groove 2. A guide groove 301 is provided on the inner wall of the receiving groove 2. A guide block 302 is connected to the side wall of the extension rod 3 corresponding to the position of the guide groove 301. The guide block 302 extends into the guide groove 301 and cooperates with it to limit the extension rod 3 while ensuring the stability of movement and preventing it from leaving the working range of the receiving groove 2.

[0024] A reset spring 4 is connected between the extension rod 3 and the bottom surface of the inner cavity of the storage groove 2. An installation plate 5 is provided on the upper side of the extension rod 3. The installation plate 5 is L-shaped and has multiple sets of installation holes on its side wall. The installation holes cooperate with external installation bolts to install the entire device on an external mobile device, thereby driving the entire device to move in the river to carry out dredging work.

[0025] An adjustment mechanism 6 is provided between the extension rod 3 and the mounting plate 5 to adjust both. The adjustment mechanism 6 includes an adjustment plate 601 connected to the upper end of the extension rod 3. A set of longitudinally penetrating adjustment holes 602 are provided on the side wall of the adjustment plate 601. A screw 603 and a limiting rod 604 are respectively provided in the set of adjustment holes 602. The inner wall of the adjustment hole 602 corresponding to the position of the screw 603 is provided with threads. The upper end of the mounting plate is mounted on a drive motor. The power output end of the drive motor is connected to the screw 603. The screw 603 engages with the adjustment hole 602 through the threads. At the same time, the screw 603 limits the rotation angle of the extension rod 3, thereby changing the overall height of the device to the position above the riverbed.

[0026] A stirring rod 7 is rotatably connected to the lower end of the mounting rod 1. A drive motor 701 is installed in the inner wall of the mounting rod 1.

The crushing toothed plate 702 crushes the sludge under the drive of the stirring rod 7, so that the suction pipe can suck up the sludge more quickly and effectively.

[0027] Mounting plate 5 is connected to a protective cover 8 on the side wall outside the stirring rod 7. The protective cover 8 is a mesh cover and is semi-circular in shape. While blocking the crushed silt, it allows water to flow smoothly. A guide wheel 801 is rotatably connected to the side wall of the protective cover 8. With the cooperation of the return spring 4 and the guide wheel 801, the stirring rod 604, the crushing tooth plate 702 and the protective cover 8 can be adjusted to a suitable height to adapt to the riverbed environment. A coil spring is provided at the rotatable connection between the guide wheel 801 and the protective cover 8. The coil spring allows the guide wheel 801 to change a certain angle to facilitate the movement of the device on the upper side of the riverbed.
