Detailed Description
The present utility model will be further described with reference to the accompanying drawings and detailed description, wherein it is to be understood that, on the premise of no conflict, the following embodiments or technical features may be arbitrarily combined to form new embodiments.
Referring to fig. 1-4, a closed-end grab sampler of the present embodiment includes two grabs 1, and two sets of connection mechanisms mounted on the two grabs 1, wherein a first connection rod 2 and a second connection rod 3 are rotatably connected between the two sets of connection mechanisms, and a driving mechanism is mounted on the first connection rod 2 and the second connection rod 3 together, so that the two grabs 1 can simultaneously open and close;
the driving mechanism comprises a unhooking mechanism, two fixed blocks 4 arranged outside the first connecting rod 2, a first roller 5 arranged outside the second connecting rod 3, and a steel wire rope 6 and a second roller 12 arranged between the two fixed blocks 4;
the grabbing ends of the two grab buckets 1 are provided with a plurality of grabbing teeth 11, and materials can be conveniently grabbed through the plurality of grabbing teeth 11.
The connecting mechanism comprises a first connecting piece 8 movably connected to the tops of the two grab buckets 1 and a second connecting piece 9 movably connected to the side edges of the two grab buckets 1, wherein the two first connecting pieces 8 are both rotatably connected to the outside of the first connecting rod 2, and the two second connecting pieces 9 are both rotatably connected to the outside of the second connecting rod 3.
