Description

Technical Field

[0001] The utility model relates to the technical field of mud sample taking, in particular to a toothed connecting rod type mud grabbing bucket. Background Art

[0002] When investigating and studying water ecology, grab buckets are often used to collect a large number of samples. However, since the traditional grab bucket structure is too simple, the following problems may occur during use: 1. The bucket lacks a fixed structure. When the bucket is extended into the mud, it is easy for the bucket to close due to resistance, resulting in insufficient mud entering the bucket, causing failure in mud sample collection; 2. The bottom of the bucket is not closed tightly. When the grab bucket is picked up, a large amount of mud sample leaks out from the gap at the bottom of the bucket, reducing the mud sample collection effect, and easily causing the loss of fine particles in the mud sample, resulting in changes in the content of various substances in the mud sample, and reducing the accuracy of mud sample research.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-9The utility model provides a technical solution: a toothed connecting rod type mud bucket, comprising a vertically arranged connecting pipe 1, two corresponding mud buckets 3 are installed at the bottom of the connecting pipe 1 through a movable connecting shaft 12, the tops of the two mud buckets 3 are provided with a spring assembly 2, and the inner side of the edge of the opening at the bottom of the mud bucket 3 is provided with a toothed plate 4, a grab tube 7 is movably installed on the top of the connecting pipe 1, and handles 8 are movably installed on the top two ends of the grab tube 7 through a rotating assembly 9, a traction rope 5 is provided through the interior of the connecting pipe 1 and the grab tube 7, and the bottom part of the traction rope 5 is forked to form a traction branch rope 501, and the bottom of the traction branch rope 501 is fixedly connected to the two ends of the top of the mud bucket 3.

[0030] In this embodiment, the bottom of the connecting tube 1 is provided with two arcuate through-slots 103. The spring assembly 2 includes two arcuate rods 201, each mounted on the upper surface of the two mud buckets 3. One end of each arcuate rod 201 extends into the through-slots 103. A compression spring 202 is sleeved on the outer side of the arcuate rod 201, and the diameter of the compression spring 202 is larger than the diameter of the through-slots 103. With this arrangement, when the traction rope 5 pulls the mud bucket 3 to rotate, the elastic force of the compression spring 202 is overcome, forcing the arcuate rod 201 to pass through the through-slots 103, allowing the mud bucket 3 to rotate upward around the movable connecting shaft 12, thereby opening the mud bucket 3. When the mud bucket 3 loses the traction of the traction rope 5, the compression spring 202 loses its extrusion force, and the elastic force of the compression spring 202 pushes the mud bucket 3 outward, causing the mud bucket 3 to rotate downward around the movable connecting shaft 12, until the mud bucket 3 is fully closed.

[0031] In this embodiment, the outer ends of the two toothed plates 4 are provided with meshing digging teeth 401. The toothed plates 4 are provided with a plurality of mounting holes 402, through which the toothed plates 4 can be bolted to the inside of the mud bucket 3. By providing the stainless steel toothed plates 4 inside the bottom opening of the mud bucket 3, the digging teeth 401 on the toothed plates 4 can be used to more conveniently insert the mud bucket 3 into the mud. At the same time, due to the meshing of the digging teeth 401, when the mud bucket 3 is closed, the digging teeth 401 are cross-coupled and the two toothed plates 4 are tightly coupled together, thereby making the mud bucket 3 more tightly closed and preventing mud sample from leaking from the gap at the bottom of the mud bucket 3.

[0032] In this embodiment, an extension tube 6 is provided between the connecting tube 1 and the grab tube 7. The extension tube 6 can extend the overall length of the grab bucket 3, allowing the bucket 3 to reach deeper into the silt, thereby widening the sampling range of the collector.

[0033] In this embodiment, a first connecting ring 102 is provided at the top of the connecting tube 1, a first connecting groove 602 and a second connecting ring 601 are provided at the bottom and top of the extension tube 6, respectively, and a second connecting groove 703 is provided at the bottom of the gripping tube 7. The inner walls of the first connecting groove 602 and the inner walls of the second connecting groove 703 are both provided with identical internal threads, and the outer walls of the first connecting ring 102 and the outer walls of the second connecting ring 601 are both provided with identical external threads, with the internal threads corresponding to the external threads. The threaded fit between the first connecting ring 102 and the second connecting groove 703 allows the gripping tube 7 to be mounted on the connecting tube 1, facilitating sampling of the grabbing bucket 3. The threaded fit between the first connecting ring 102 and the first connecting groove 602, and between the second connecting ring 601 and the second connecting groove 703, allows the extension tube 6 to be mounted between the connecting tube 1 and the gripping tube 7, thereby increasing the overall length of the grabbing bucket 3.

[0034] In this embodiment, a traction ring 13 is provided on the top outer side of the mud bucket 3, and threading holes 101 are opened on both sides of the bottom of the connecting pipe 1. The traction rope 501 passes through the threading holes 101 and is fixedly connected to the traction ring 13.

[0035] In this embodiment, a downwardly curved L-shaped positioning plate 11 is provided on one side of the grip tube 7, and a fixing ring 10 is provided on the top of the traction rope 5. As a preferred embodiment, the inner side of the positioning plate 11 can be mounted on the outer side of the grip tube 7 via a movable bearing, so that the positioning plate 11 can rotate about its axis. The downward extension of the outer end of the positioning plate 11 can be rotated upward to facilitate the removal of the fixing ring 10 from the positioning plate 11. The positioning plate 11 can be used to limit and fix the fixing ring 10, thereby limiting and fixing the traction rope 5, and the traction rope 5 can be used to keep the mud bucket 3 in an open state.

[0036] In this embodiment, the top two sides of the grip tube 7 extend horizontally outward to form an extension portion 701, and a connecting groove 702 is provided on the outer side surface of the extension portion 701. A limiting ring is provided at the opening of the connecting groove 702. The rotating component 9 includes a rotating disk 901, and a connecting disk 902 is provided on the inner side of the rotating disk 901, which extends into the limiting ring and corresponds to the connecting groove 702. As a preferred embodiment, a connecting column is provided between the connecting disk 902 and the rotating disk 901, and the connecting column passes through the limiting ring and can rotate flexibly in the limiting ring. The inner end of the handle 8 is provided with a first connecting plate 801, and the outer end of the rotating disk 901 is provided with a second connecting plate 903 corresponding to the first connecting plate 801, and the first connecting plate 801 and the second connecting plate 903 are movably connected through a connecting shaft. With such a configuration, the cooperation between the connecting plate 902 and the connecting groove 702 is utilized to enable the rotating plate 901 to rotate flexibly on the extension portion 701, thereby enabling the handle 8 to rotate flexibly. At the same time, the cooperation between the first connecting plate 801, the second connecting plate 903 and the connecting shaft enables the handle 8 to be folded and flush with the grip tube 7 for easy storage.

[0037] Working principle:

[0038] According to the depth of the silt to be mined, choose whether to install the extension tube 6. When collecting mud samples, pull the traction rope 5 upward through the fixed ring 10, use the traction rope 5 and the traction branch rope 501 to pull the mud bucket 3 upward, and overcome the elastic force of the extrusion spring 202 to make the mud bucket 3 rotate upward with the movable connecting shaft 12 as the center, and then open the two mud buckets 3, and wrap the traction rope 5 around the grab tube 7, use the fixed ring 10 and the positioning plate 11 to limit and fix the traction rope 5, so that the mud bucket 3 remains in the open state, and use the rotating assembly 9 to rotate the handle 8 to rotate the first connecting plate 801 and the second connecting plate 903 on the handle 8 to the horizontal The surface, that is, the connecting axis between the first connecting plate 801 and the second connecting plate 903 is vertically downward, and the handle 8 is held to press the mud bucket 3 downward so that the mud bucket 3 is deeply inserted into the silt, so that the silt can fully enter the mud bucket 3, and the limiting fixation of the positioning plate 11 on the fixing ring 10 is released, and the winding of the traction rope 5 is loosened. When the mud bucket 3 loses the traction of the traction rope 5, the extrusion spring 202 loses the extrusion force, and the elastic force of the extrusion spring 202 is used to push the mud bucket 3 outward, so that the mud bucket 3 rotates downward with the movable connecting axis 12 as the center until the mud bucket 3 is completely closed, and the mud sample is sealed inside the mud bucket 3, and the mud bucket 3 is lifted out by the handle 8 to take out the mud sample.
