Description
Technical Field
[0001] The utility model relates to the technical field of low mud cleaning grab buckets, in particular to a grab bucket type bottom mud sampler capable of automatic cleaning. Background Art
[0002] This sediment sampler is mainly used for collecting sediment and benthic animals in lakes. During the sampling process on lakes, due to wind and waves, weather and other reasons, the sampling efficiency is low. If the sampling purpose is not achieved due to various reasons such as the inability of the sediment sampler to collect sediments or the small number of samples in the collected sediments, the sediment collection work must be carried out again. Therefore, the efficiency of the sediment sampler seriously affects the progress and quality of the relevant water environment survey;
[0003] During the sampling process of the existing grab-type mud sampler, the mud at the bottom of the lake is relatively viscous and is easily attached to the inner wall of the mud sampler during the bagging process. Sometimes, even a large piece of mud cannot fall off. The mud on the inner wall of the mud sampler has to be cleaned for each sampling point. The composition of lake bottom mud is complex, and there is no lack of some inorganic toxic components, pathogenic microorganisms and parasite eggs. Mud samplers are mostly made of metal and have sharp edges. It is very unsafe to clean the attached mud by hand on a shaking boat.
[0004] The existing grab type mud sampler is connected with a single connecting rod. After the mud sampling grab touches the bottom, the groove leaves the short rod so that the connecting rod can be disengaged from the short rod, allowing the left grab and the right grab to be closed. However, in the actual sampling process, the connecting rod is often unable to be disengaged normally because it is too close to the short rod, and the left grab and the right grab cannot be closed, resulting in low sampling efficiency.
[0005] Therefore, it is necessary for us to design a cleanable grab-type sediment sampler which has high safety factor, convenient operation and can be easily produced. Summary of the invention

[0009] Preferably, the grab bucket comprises a left grab bucket and a right grab bucket, the left grab bucket and the right grab bucket are connected by a cross beam, and a second rotating shaft is provided at the bottom of the cross beam.
[0010] Preferably, there are two buckle hooks in total.
[0011] Preferably, a plurality of air-permeable overflow holes are provided at the lower portion of the outer wall of the grab bucket.
[0012] Preferably, a slideway is provided on the outer wall of the grab bucket near the upper part of the operating rod, and a cleaning mechanism is provided in the slideway, the cleaning mechanism includes a slider, a fixed block, a slider base, a linear spring and a wire rope; the slider is embedded in the slideway and slides back and forth, a slider base is provided at the bottom of the slider, one side of the slider base is connected to the wire rope, the other end of the slider base away from the wire rope is connected to a linear spring, the other end of the linear spring is connected to a fixed block, and the fixed block is arranged on the inner wall of the grab bucket near the crossbeam.
[0013] Preferably, there are two operating rods, which are respectively fixed at the two ends of the top of the grab bucket. The operating rod is a hollow rod, one end of which is provided with a hole, and a steel wire rope is embedded inside the operating rod. One end of the steel wire rope passes through the hole and is connected to the slider base. The other ends of the two operating rods are hingedly connected away from the hole.

DETAILED DESCRIPTION
[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: an automatically cleanable grab bucket type bottom mud sampler, comprising a grab bucket 1, an opening and closing mud grabbing mechanism and a cleaning mechanism, wherein an opening and closing mud grabbing mechanism is provided on the outer wall of the grab bucket 1, and the opening and closing mud grabbing mechanism is used to grab low mud, and a cleaning mechanism is provided on the inner wall of the grab bucket 1, and the cleaning mechanism is used to clean the low mud in the grab bucket 1.
[0024] Furthermore, the opening and closing mud grabbing mechanism includes a hook 2, which is hingedly arranged on the outer wall of the grab bucket 1. An operating rod 4 is also arranged on the upper part of the outer wall of the grab bucket 1, and the operating rod 4 is used to control the grab bucket 1 to realize the opening and closing function. If it is necessary to grab the low mud in the water, the hooks 2 on the surface of the grab bucket 1 are firstly connected to each other, and the connected grab bucket 1 is thrown into the water, so that the grab bucket 1 sinks in the water. Since the grab buckets 1 are connected by the hooks 2, the grab bucket 1 remains in an open state during the sinking process in the water. After the grab bucket 1 sinks to the bottom of the water, the staff controls the operating rods 4 at both ends to press downward, so that the left grab bucket and the right grab bucket rotate upward in opposite directions. At this time, the hooks 2 at both ends that are connected also move in opposite directions. After the hooks 2 at both ends move in opposite directions for a certain distance, the clamping heads of the hooks 2 at both ends will automatically disengage.
[0025] Furthermore, the grab 1 includes a left grab and a right grab, which are connected by a crossbeam 5, and a second rotating shaft 16 is provided at the bottom of the crossbeam 5; after the hook 2 of the grab 1 falls off, the left grab and the right grab move inward at the same time by their own gravity, and the grab 1 is closed to grab the low mud in the water. When the grab 1 is closed, the wire rope 15 is tightened, driving the slider 3 to slide along the slide 6 to the end, thereby driving the two silicone slide bars 14 in the grab 1 to move from bottom to top to the top of the grab 1, so as to facilitate the bottom mud to enter the inside of the grab 1.
[0026] Furthermore, there are two buckle hooks 2, and the heads of the buckle hooks 2 are in an "L" shape.
[0027] Furthermore, a plurality of air-permeable overflow holes 7 are provided at the lower portion of the outer wall of the grab bucket 1; after the low-lying mud is grabbed, the excess water in the low-lying mud is discharged through the air-permeable overflow holes 7.
[0028] Furthermore, a slideway 6 is provided on the outer wall of the grab 1 near the upper part of the operating rod 4, and a cleaning mechanism is provided in the slideway 6, which includes a slider 3, a fixed block 8, a slider base 10, a linear spring 11 and a wire rope 15; the slider 3 is embedded in the slideway 6 and slides back and forth, and a slider base 10 is provided at the bottom of the slider 3, and a wire rope 15 is connected to one side of the slider base 10, and the other end of the slider base 10 away from the wire rope 15 is connected to a linear spring 11, and the other end of the linear spring 11 is connected to a fixed block 8, and the fixed block 8 is arranged on the inner wall of the grab 1 near the crossbeam 5; there are two operating rods 4, and the operating rods 4 are fixed on the top of the grab 1 At both ends, the operating rod 4 is a hollow rod, one end of the operating rod 4 is provided with a hole, and the wire rope 15 is embedded in the operating rod 4, one end of the wire rope 15 passes through the hole and is connected to the slider base 10, and the two operating rods 4 are hingedly connected at the other end away from the hole; when the low mud needs to be cleaned after grabbing, the staff first controls the operating rod 4 to press inward, so that the operating rods 4 at both ends move in the same direction to drive the left and right grab buckets of the grab bucket 1 in the opposite direction, rotating from bottom to top, and opening the grab bucket 1 from a closed state. After opening, the slider 3, due to the lack of the tension of the wire rope 15, is driven by the elastic force of the linear spring 11 itself to move the slider 3 along the slideway 6 toward the crossbeam 5.
[0029] Furthermore, the other end of the wire rope 15 on the slider base 10 away from the linear spring 11 is also connected to the limiter 9, and there are two limiters 9 in total, which are arranged above the inner wall of the grab bucket 1, and a limit ring 17 is arranged inside the limiter 9; and when the sliders 3 at both ends move, they also drive the wire rope 15 to pull the limiter 9 inward, so that the linear spring 11 is protected by the limiter 9 to prevent the linear spring 11 from exceeding the elastic limit and failing; the limit ring 17 inside the limiter 9 can share the gravity of the grab bucket 1 and the bottom mud, so as to prevent the slider 3 and the linear spring 11 from being damaged during the pulling process due to its own excessive weight.
[0030] Furthermore, the cleaning mechanism also includes a connecting rod 12, a first rotating shaft 13 and a silicone slide bar 14; one end of the connecting rod 12 is connected to the bottom of the slider base 10, and the other end of the connecting rod 12 is connected to the silicone slide bar 14, and the connecting rod 12 and the silicone slide bar 14 are connected through the first rotating shaft 13, and the other end of the silicone slide bar 14 is away from the connecting rod 12 and is hinged to the second rotating shaft 16 of the grab bucket 1; and the sliders 3 at both ends slide along the slideway 6 while driving the slider base 10 to move together, so that the slider base 10 moves while pushing the connecting rod 12 and the silicone slide bar 14 inward, so that the silicone slide bars 14 at both ends slide from top to bottom on the inner wall of the grab bucket 1, and the low mud in the grab bucket 1 is pushed out, thereby achieving a cleaning effect.
