Problems solved by technology

Due to the unreasonable structural design of ordinary grabs, when using grabs to grab powder materials with small particles, large dust is often generated during the process of opening and unloading the grabs, which is not conducive to the health of on-site workers. The surrounding environment also causes some pollution

Embodiment Construction

[0010] The invention relates to a grab bucket for loading and unloading bulk materials. Its structure includes a grab bucket main body and a dust suction device connected with the grab bucket main body, which constitute an air suction grab bucket.

[0011] The following combines examples and Figure 1 to Figure 3 The present invention is further described.

[0012] The structure of the air suction grab provided by the present invention is the same as that of the prior art, mainly including upper beam 3, support rod 4, lower beam 6, pulley 7, lug 8, jaw plate 9, hinge shaft 10, steel wire rope 11.

[0013] In the air suction grab provided by the present invention, the dust collection device is a remote control dust collection device. This dust suction device mainly is made up of bellows 2, control box 13, accumulator 14, and they are fixedly contained on the upper beam 3. A suction pipe 5 is connected to the bottom of the bellows 2, and the lower end of the suction pipe exte...

Abstract

The present invention provides an air absorption grab bucket used for charging and discharging bulk cargo material, which comprises a grab bucket body and a dust suction device which is connected withthe grab bucket. The present invention adopts a novel structure, so during the process of discharging, a remote controller can be used for starting an exhaust fan (15) in the dust suction device which is installed at a grab bucket crossbeam (3); an air absorption pipe (5) is used for absorbing the flying dust around the grab bucket; the dust is absorbed to the lower layer of the fan by the air absorption pipe, and air is exhausted from an air outlet through a filter screen, so as to realize that the discharging process of the grab bucket produces no dust, which can improve the environment ofthe working site, avoids causing pollution to the surrounding environment and at the same time is in favor of the body health of the field working personnel.

Description

technical field [0001] The invention relates to a material grasping device of a crane, in particular to an air suction grab. Background technique [0002] At present, major domestic ports mainly use grab cranes for loading and unloading bulk materials. Grab buckets are a kind of pick-up device for cranes to load and unload bulk materials. The structure mainly includes steel wire ropes, pulleys, upper beams, lower beams, and struts. and jaw plates. Due to the unreasonable structural design of ordinary grabs, when using grabs to grab powder materials with small particles, large dust is often generated during the process of opening and unloading the grabs, which is not conducive to the health of on-site workers. The surrounding environment also causes certain pollution. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an air suction grab, which can realize dust-free operation during the unloading process. [0004]...
