Problems solved by technology
[0002] The traditional collection equipment is heavy and difficult to transport. When operating the existing collection equipment, manual excavation is often used. The hands of the staff often rub against the hemp rope, which greatly damages the hands of the staff, thereby reducing the overall sampling cost of the collection personnel. efficiency
Moreover, due to the manual operation of traditional collection equipment, there are many restrictions on the use of the device, and the scope of application is narrow.

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 bucket type mud collecting device and relates to the environment detection device field. The device comprises a sampling portion, a pulling rope and a starting device. The sampling portion comprises a grab bucket and a mud sample storage warehouse. The grab bucket and the mud sample storage warehouse are rotatably connected. The grab bucket is provided with a springback device. When there is no external stress on the springback device, a closed cavity is formed between the grab bucket and the mud sample storage warehouse. The starting device comprises a starter and a spring component, the spring component is arranged on the mud sample storage warehouse and is connected to the pulling rope, the starter is slidably connected with the pulling rope, and the grabbucket is detachably connected to the spring component through a grab bucket fixing portion. During delivery and sampling processes, manpower is not needed, efficient sampling is ensured during repeated sampling, and the device is suitable for collection of river bottom mud samples of various terrains and various depths.
