Technical Field

[0001] The invention belongs to the technical field of canal desilting, and specifically refers to a canal desilting device for water conservancy and hydropower construction. Background Art

[0002] In water conservancy and hydropower construction, canal dredging is of vital importance. With the continuous development of engineering construction, the efficiency and quality requirements for canal dredging are becoming higher and higher.

[0003] In the process of canal dredging, there are the following problems: First, when using a sewage pump for dredging, the effect of the sewage pump is limited for some relatively viscous silt and the harder sludge layer deposited at the bottom of the canal, and it is difficult to achieve thorough dredging, and the sewage pump is easily blocked by debris, large pieces of sludge, etc.; Second, in order to reduce the blockage problem, some canal dredging devices will add a mud turning plate to turn up the silt at the bottom of the canal for subsequent treatment. However, in actual operation, the mud turning plate often adheres to a large amount of silt after use, and this silt is difficult to clean. Due to the complex canal environment, manual cleaning of the mud turning plate is not only inefficient, but also poses certain safety risks. At the same time, if the silt on the mud turning plate is not cleaned in time, it will affect the effect of its next use, reduce the dredging efficiency, and may even hinder the normal operation of the device.

On the outer wall of the rotating shaft 13 in the circumferential direction, there are multiple groups of mud turning plates 14 in a circular array with the central axis of the rotating shaft 13 as the axis. The mud turning plates 14 are located at the feeding port of the mud shoveling hopper 2 and are movably contacted with the bottom of the mud shoveling hopper 2. A shovel plate 17 is fixedly provided on the side end of the mud turning plate 14 away from the rotating shaft 13. The mud shoveling surface of the shovel plate 17 is arranged in an inclined surface. During the rotation of the mud turning plate 14, the shovel plate 17 contacts the ground. Since there is a certain angle between the shovel plate 17 and the mud turning plate 14, the sludge can be easily scraped and collected under the action of the shovel plate 17. A traveling force driven mud turning component 15 is fixedly installed on the L-shaped support plate 12. The traveling force of the vehicle body 1 itself is used to drive the mud turning plate 14 to rotate.

The auxiliary wheel 1501 rotates and drives the driving gear 1502 to rotate through the transmission belt 1 1504. The driving gear 1502 drives the driven gear 1503 to rotate. After the driven gear 1503 changes the rotation direction and speed, it drives the rotating shaft 13 to rotate through the transmission belt 2 1505. The rotating shaft 13 drives the mud turning plate 14 to continuously rotate toward the mud shoveling bucket 2 to turn over the mud, and turn the silt into the mud shoveling bucket 2.

After the sludge is collected to a certain extent, when it is necessary to clean the residual sludge in the mud shoveling hopper 2 and the mud turning plate 14, the cylinder 9 lifts the mud shoveling hopper 2, and then the tipping bucket assembly 11 drives it to flip over and dump the sludge into the material receiving chamber 505. The sewage pipe 603 is screwed to the sewage pump 602, and the sewage pipe 603 can be rotated away without affecting the flushing of the mud turning plate 14 and the mud shoveling hopper 2.

[0024] When in use, the vehicle body 1 travels to the canal, and the cylinder 9 is started according to the depth of the canal. The cylinder 9 drives the mud shovel hopper 2 to descend to the bottom of the canal through the connecting plate 7, and the auxiliary wheel 1501 contacts the bottom surface of the canal. When the vehicle body 1 travels forward, the auxiliary wheel 1501 rotates and drives at the same time. The auxiliary wheel 1501 rotates and drives the driving gear 1502 to rotate through the transmission belt 1 1504, and the driving gear 1502 drives the driven gear 1503 to rotate.

The high-pressure nozzle 403 flushes and cleans the mud hopper 2 and the mud turning plate 14, and the impact force generated when the high-pressure nozzle 403 sprays water will cause the mud turning plate 14 on the rotating shaft 13 to rotate, thereby evenly flushing the multiple groups of mud turning plates 14 on the rotating shaft 13.
