Description

Technical Field

[0001] The present invention belongs to the technical field related to water conservancy construction, and in particular relates to a mobile and convenient self-cleaning device for water conservancy construction dredging machinery. Background Art

[0002] In various water conservancy projects, there is mud and silt to varying degrees. If not dealt with in time, the river channel will be blocked. Once a flood occurs after the river channel is blocked, serious consequences and losses will occur. Therefore, dredging equipment is needed to perform dredging regularly.

[0003] Problems with existing technologies:

[0004] 1. The existing self-cleaning device of dredging machinery usually extracts the sludge in the river channel when cleaning the sludge, and transports the extracted sludge to a designated location for treatment, so as to achieve the effect of dredging the river channel. However, the sludge contains a large amount of water, which takes up more space, resulting in low cleaning efficiency.

[0005] 2. In the process of cleaning silt, the existing dredging mechanical self-cleaning device is generally equipped with moving wheels at the bottom of the device. Although it can conveniently drive the dredging device to move, when the dredging device is placed beside the river during the dredging process, it is easy for the dredging device to roll into the river, reducing the safety of the dredging device.

[0006] 3. The existing self-cleaning device for dredging machinery is not convenient for cleaning the sludge collected inside the device after the sludge cleaning is completed, which makes it inconvenient to clean the inside of the device after use.

[0007] 4. The existing silt-clearing mechanical self-cleaning device is prone to the presence of large stone particles and other impurities in the sludge during the pumping process, which can easily cause the device to become blocked during the pumping process, thereby affecting the normal pumping of the device.

[0008] 5. The existing self-cleaning devices for dredging machinery are generally inconvenient to break up the silt compacted on the surface during use, and the operator needs to manually clean the silt compacted on the surface before the subsequent pumping work can be carried out, which affects the pumping efficiency of the device.

[0052] The working principle of the present invention is:

[0053] When using the device for dredging, first move the device to the designated position, then remove the fixing frame 2 from the cart body 1 by using the two pulling handles 11 provided. In this process, the concave plate 2 64 is driven downward by rotating the threaded rod 2 65 with the cooperation of the four L-shaped rods 62, thereby driving the four ground-inserting nail rods 2 61 to pass through the two limiting holes provided inside the two limiting plates 63 and move downward a certain distance. At this time, the fixing frame 2 is placed at the designated position and the four ground-inserting nail rods 2 61 are only inserted into the dredging position to ensure the stability of the fixing frame 2 during the dredging process.

[0054] Then, the dual-axis motor 94 is started to drive the breaking rod 92 to rotate, so that the silt can be broken up during the silting process to prevent the silt from sticking together, and in the process of breaking up the silt, the rotation of the bevel gear 1 96 can drive the rotating rod 3 98 to rotate under the action of the provided bevel gear 2 97, and the rotation of the rotating rod 3 98 can drive the mounting rod 914 to reciprocate in the front-to-back direction under the cooperation of the provided L-shaped push rod 913, the pushing frame 912, the limiting block 911 and the limiting rod 910, and then the cleaning push plate 916 can be driven to reciprocate in the front-to-back direction under the action of the provided mounting block 915, thereby achieving the cleaning process of impurities on the surface of the L-shaped filter plate 8;

[0055] In the process of breaking up the sludge, the pump 10 is started to pump the sludge into the collection box 19 with the cooperation of the pumping pipe 21 and the pumping hose 12. In the process of pumping the sludge into the collection box 19, the L-shaped filter plate 8 and the fixing frame 2 can filter the larger solids or branches and other impurities in the sludge to avoid clogging of the device. When the sludge enters the collection box 19, the drain valve provided on the drain pipe 32 is opened, and with the cooperation of the filter net 33 and the drain pipe 32, a large amount of water contained in the sludge entering the collection box 19 can be discharged from the collection box 19 to avoid the water occupying more space. At this time, the collection and treatment process of the sludge can be achieved;

[0056] When the device is used up and the sludge collected in the collecting box 19 needs to be dumped, the motor 2 79 is started to drive the threaded rod 3 74 to rotate, and then the connecting frame 72 can be driven to move upward under the action of the fixed rod 2 73. In the process of driving the connecting frame 72 to move upward, the collecting box 19 can be driven to rotate upward around the hinge shaft 36 under the cooperation of the fixed cross plate 77, the sliding rod 78, the fixed rod 3 76 and the fixed plate 6 75. At this time, the electric hydraulic rod 15 is started to drive the connecting cross plate 13 to move downward, and then the retaining plate 26 can be driven to rotate upward around the rotating rod 1 27 under the cooperation of the toothed plate 18, the meshing gear 17, the rotating rod 1 27 and the L-shaped plate 25, so as to achieve the opening process of the rear end of the collecting box 19, and the sludge in the collecting box 19 can be conveniently dumped out at this time.

[0057] During the dredging process of the device, the rotation of the output shaft of the motor 510 drives the worm 59 to rotate, and then the two worm wheels 58 can drive the two rotating rods 56 to rotate relative to each other. Through the relative rotation of the two rotating rods 56, the two mounting horizontal plates 512 can be driven to move downward with the cooperation of the rotating plate 54, T-shaped sliding sleeve 53, fixed horizontal bar 511 and fixed plate four 52. Then, with the cooperation of the vertical rod 51, the anti-skid bottom plate 46 can be driven to move downward until the anti-skid bottom plate 46 overlaps the ground. At this time, the movement of the device can be restricted, increasing the stability of the device during use. Then, according to the actual situation, the two threaded rods 45 can be rotated to drive the two mounting plates 44 to move downward, thereby driving the four ground nail rods 42 to pass through the anti-skid bottom plate 46 until they are inserted into the soil, thereby further increasing the stability of the device during use.

[0058] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
