Problems solved by technology

However, in the actual use process, the dirt cleaning grab needs to salvage the dirt out of the water surface for treatment, and there are defects such as complicated sewage treatment process, low treatment efficiency and high treatment cost.
In addition, because there are often large hard dirt on the trash rack, such as wood or stones, etc., this makes the shovel teeth often be crushed by the dirt on the trash rack when they move down the trash rack. Jamming, which prevents effective downward movement of the grapple

Embodiment 1

[0053] The utility model relates to a cleaning machine, which includes a grab bucket, and a crushing device for underwater crushing of dirt is arranged in the grab bucket. The crushing device includes a crushing drum 4 and an auxiliary drum 5. The crushing drum 4 can rotate at a high speed underwater, and the high-speed rotating crushing drum 4 and the auxiliary drum 5 cooperate to crush dirt.

[0054] In this embodiment, the crushing device further includes a seat body 6, a V-shaped connecting rod 7 and a driving hydraulic cylinder 16, and the number of the seat body 6, the V-shaped connecting rod 7 and the driving hydraulic cylinder 16 is preferably two sets; Wherein, the cylinder ends of two sets of driving hydraulic cylinders 16 are all movably connected to the two ends of the grab bracket 1 through bearings, and the two sets of driving hydraulic cylinders 16 are symmetrical. Two sets of pedestals 6 are fixed in the grab bucket, and the shafts at two ends of the auxiliary ...

Embodiment 2

[0059] This embodiment is basically the same as Embodiment 1, the main difference is that: the outer surface of the auxiliary cylinder 5 is fixedly provided with a connecting strip 9, and the fixed knife 8 is fixed on the connecting strip 9 by bolts. Wherein, the connecting strip 9 is fixed or integrally formed on the auxiliary cylinder 5 by bolts.

Embodiment 3

[0061] The utility model relates to a cleaning machine, which includes a grab bucket, and a crushing device for underwater crushing of dirt is arranged in the grab bucket. The crushing device includes a crushing drum 4 and an auxiliary drum 5. The crushing drum 4 can rotate at a high speed underwater, and the high-speed rotating crushing drum 4 and the auxiliary drum 5 cooperate to crush dirt.

[0062] In this embodiment, the crushing device further includes a seat body 6, a V-shaped connecting rod 7 and a driving hydraulic cylinder 16, and the number of the seat body 6, the V-shaped connecting rod 7 and the driving hydraulic cylinder 16 is preferably two sets; Wherein, the cylinder ends of two sets of driving hydraulic cylinders 16 are all movably connected to the two ends of the grab bracket 1 through bearings, and the two sets of driving hydraulic cylinders 16 are symmetrical. Two sets of seat bodies 6 are fixed in the grab bucket, and the axles at the two ends of the auxil...

Abstract

The invention discloses a trash remover. The trash remover comprises a grab bucket, and a crushing device used for crushing trash underwater is arranged in the grab bucket. The trash remover has the technical effects that trash in the grab bucket can be crushed after being grabbed underwater, the size of the trash is reduced so that the trash can pass through a trash rack smoothly, the trash can be treated without being fished out of water, the treatment procedure is simplified, the treatment efficiency is improved, and the treatment cost is reduced.

Description

technical field [0001] The invention relates to the field of water conservancy and hydropower engineering, in particular to a cleaning machine. Background technique [0002] With the increasing environmental pollution, hydropower stations and pumping stations are increasingly threatened by pollutants such as tree branches and leaves, crop weeds, and domestic garbage. In order to ensure the safe and normal operation of hydropower stations and pumping stations, it is usually necessary to set up a sewage cleaning machine to remove the dirt on the bottom of the hydropower dam and the dirt attached to the trash rack without stopping the machine or emptying the reservoir area. [0003] In the prior art, a grab-type cleaning machine is usually used to remove dirt. For example, the prior art with the Chinese patent announcement number "CN204849715U" disclosed a mechanical pressurized cleaning grab on December 9, 2015. , the technical solution is: including rotary rake, shovel teeth...
