Description

Technical Field

[0001] This utility model relates to the field of cleaning grab bucket technology, and in particular to a cleaning grab bucket. Background Technology

[0002] A pumping station is a general term encompassing structures such as irrigation and drainage pumping stations, intake pump houses, and outlet pump houses. Pumping stations regulate the water level of reservoirs, rivers, or lakes by controlling the start-up, shutdown, and flow rate of the pumps. During dry seasons or when water levels are too low, pumping stations can pump water into reservoirs to increase water levels and storage capacity. During rainy seasons or when water levels are too high, pumping stations can pump out excess water to prevent reservoir overflow or flood disasters. However, during floods, the floodwaters wash aquatic plants, dead branches, and garbage from upstream to the pumping station's intake, clogging it. At this time, a grab bucket is needed to clear the garbage. Current grab buckets generally consist of openable and closable grab plates and a controller to control the bucket's raising and lowering. Under the control of the controller, the grab bucket grabs the garbage at the intake. Because current grab buckets use two grab plates to open and close to grab garbage, when the two plates are closed, the sides of the grab bucket are not sealed, which can easily cause garbage to fall from the sides of the grab bucket as it rises. This fallen garbage may re-enter the water body, causing secondary pollution and affecting water quality and the ecological environment. Furthermore, for debris tightly attached to the grates or embedded in the grates, simple grabbing is insufficient; workers may need to operate repeatedly and constantly adjust the grab bucket angle, which is time-consuming and labor-intensive. When there are sharp objects in the garbage, they may damage the cleaning equipment or cause personal injury, posing a safety hazard. Utility Model Content

[0003] This utility model provides a cleaning grab bucket that can overcome some or all the defects of the prior art.

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0017] Example 1 like Figures 1 to 8 As shown, a cleaning grab bucket mainly includes a mounting frame 1, a first grab plate 2, a side grab plate 3, a second grab plate 4, and a rake tooth system 5.

[0018] Mounting bracket 1 serves as the main load-bearing structure, comprising a mounting bracket body 100. A main controller 101 is integrated at the upper center of the mounting bracket body 100. The main controller 101 integrates signal reception and execution, and wiring for connecting the motor, all using existing materials and structures. The front side of the mounting bracket body 100 is connected to the first gripping plate 2 via a hinge 103 and a first cylinder system 104. The hinge 103 consists of a protrusion 1031 with a through hole welded to the mounting bracket body 100, a hinge connector 1032 located on the first gripping plate 2, and a connecting shaft 1033 passing through both, allowing the first gripping plate 2 to rotate around the connecting shaft 1033. The first cylinder system 104 includes a first cylinder 1042 fixed to the mounting bracket body 100 via a first cylinder system fixing member 1041. The end of the first cylinder piston rod 1043 of the first cylinder 1042 is hinged to a first cylinder system passive member 1044 welded to the first gripping plate 2. When the piston rod of the first cylinder 1042 extends or retracts, it can drive the first gripper plate 2 to open and close.

[0019] The mounting bracket body 100 has side holes 106 on both its left and right sides. The side gripping plate 3 is mounted on the mounting bracket body 100 through the holes 106 via its rotating shaft 302. Nested rings 303 are fitted at both ends of the rotating shaft 302 for axial positioning. The second cylinder system 105 is fixed to the mounting bracket body 100 via a second cylinder system fixing member 1051, and the end of the second cylinder piston rod 1053 is hinged to the second cylinder system driven member 1054 welded to the rotating shaft 302. Therefore, the movement of the second cylinder 1052 can drive the side gripping plate 3 to rotate as a whole via the rotating shaft 302, thus achieving opening and closing.

[0020] The second gripper plate 4 is directly welded and fixed to the rear side of the bottom surface of the mounting frame body 100.

[0021] The first grab plate 2 consists of a first grab plate body 200 and multiple first grab plate teeth 201 at its lower edge. Multiple first grab plate fixing piles 2021 are welded laterally between adjacent grab teeth to increase structural rigidity.

[0022] The second grab plate 4 consists of a second grab plate body 400 and multiple grab teeth on its lower edge. Its structure is more complex, integrating a rake tooth system 5: a motor groove 407 is machined in the middle of its upper end; second grab plate fixing posts 4021 are welded between the grab teeth; motor shaft holes 403 and rake tooth shaft holes 404 are machined on the body; and transmission covers 405 and rake tooth shaft covers 406 are fixed to both sides by bolts for protection and sealing of the transmission components.

[0023] The rake tooth system 5 is integrated within the second gripper plate 4: the motor 501 is bolted to the motor slot 407. The motor shaft 502 extends from one end of the motor, passes through the motor shaft hole 403, and waterproof rings 5061 are fitted at both the extended and inserted ends to ensure a seal. A drive wheel 503 is keyed to the end of the motor shaft 502. The rake tooth shaft 507 passes through the rake tooth shaft hole 404, and a driven wheel 504 is keyed to one end of it, located within the transmission cover 405. The drive wheel 503 and the driven wheel 504 are connected by a belt 505. Multiple rake teeth 500 are fixedly fitted onto the rake tooth shaft 507 by keys or welding, and are located within the tooth gaps of the second gripper plate 4.

[0024] The workflow is as follows: Lowering and loosening: The worker operates the remote control to send a specified signal command to the main controller 101. Upon receiving the signal, the grab bucket is lowered to the debris area. The motor 501 is started, and the power is transmitted sequentially through the motor shaft 502, the drive wheel 503, the belt 505, and the driven wheel 504 to the rake tooth shaft 507, driving the rake teeth 500 to rotate at high speed and loosen the debris.

[0025] Grabbing: The piston rod of the first cylinder 1042 extends, pulling the first gripper plate 2 around the hinge 103 towards the second gripper plate 4 to close. Simultaneously, the piston rods of the second cylinders 1052 on both sides extend, pulling the rotating shaft 302 via the driven component 1054 of the second cylinder system, causing the side gripper plates 3 on both sides to rotate inward and close. At this point, the first gripper plate 2, the second gripper plate 4, and the two side gripper plates 3 together form a hopper to catch the debris.

[0026] Lifting and transporting: Lifting the entire grab bucket prevents captured debris from leaking out from both sides due to the obstruction of the side grab plates 3.

[0027] Unloading: Upon reaching the unloading point, the piston rods of the first cylinder 1042 and the second cylinders 1052 on both sides retract, driving the first grab plate 2 and the side grab plate 3 to open, and the debris falls down by gravity.

[0028] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, none of which exceed the protection scope of this application.

[0029] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
