Embodiment Construction
[0016] In order to better understand the essence of the present invention, the present invention will be further described below in conjunction with specific embodiments and accompanying drawings.
[0017] The present invention is applicable to the field of environmental detection devices, and the structure of specific embodiments is as follows figure 1 As shown, a grab-type mud mining device includes a mud sample storage bin 1, an outer grab 3 and an inner grab 4, the inner and outer grabs are connected by bearings, and the outer grab 3 and the inner grab 4 can be closed when they are closed. overlap to form a closed cavity with the mud sample storage bin 1. The bearings of the inner and outer grabs are provided with rebound devices to ensure the closure of the inner and outer grabs and increase the grabbing force during sampling, preferably torsion springs 7 . Both the outer grab bucket 3 and the inner grab bucket 4 are provided with grab bucket fixing ropes 5 .

The invention discloses a grab type mud mining device, which relates to the field of environmental detection devices and includes a sampling part, a traction rope and a starting device. The sampling part includes a grab bucket and a mud sample storage bin. The grab is rotatably connected to the mud sample storage bin. The grab is equipped with a rebound device; when there is no external stress on the rebound device, the grab bucket and the mud sample storage bin A closed cavity is formed between them. The starting device includes a starter and a spring component. The spring component is arranged on the mud sample storage bin and connected to the traction rope. The starter and the traction rope are slidably connected. The grab is detachably connected to the spring component through the grab bucket fixing part. The present invention does not need manpower in the feeding and sampling process, ensures high-efficiency sampling during repeated sampling, and is suitable for collecting river bottom mud samples of various terrains and depths.
