DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] like Figure 1As shown, this embodiment discloses a sample ejection device for a large-caliber sediment sampler, including a sample tube ejection module 1 and a bracket, wherein the bracket includes a sample tube bracket 5 and a sampling tube bracket 6, a pulley 4 is provided on the sample tube bracket 5, and a sampling tube 2 installed with the sample tube ejection module is placed on the sampling tube bracket 6. In this embodiment, the lengths of the sample tube bracket and the sampling tube bracket are not less than the length of the sampling tube, ensuring that after the sample tube ejection module ejects the sample tube 3 and the sample from the sampling tube 2, the sample tube 3 can fall on the sample tube bracket, thereby preventing the sample tube from falling from the bracket after being ejected, causing damage to the sample and the sample tube.

[0020] In this embodiment, the connection mode between the sample tube bracket and the sampling tube bracket is not fixed, and can be designed as an integrated structure or detachably connected by bolts. The integrated design structure is more solid, and the detachable connection is convenient for storage and transportation.

[0021] like Figure 2-3 As shown, the sample tube ejection module includes a sampling tube fixing sleeve 7, a cylinder, and an ejection plate 10. A limited slot hole 13 is provided on the sampling tube fixing sleeve, and the limited slot hole is an elliptical waist structure. A base 12 is provided below the sampling tube fixing sleeve 7, and a through hole is provided in the middle of the base. The cylinder telescopic rod 11 passes through the through hole and is connected to the ejection plate 10. A sample tube positioning plate 9 is fixedly provided above the ejection plate. The size of the sample tube positioning plate is slightly smaller than the inner diameter of the sample tube. When working, the sample tube positioning plate is inserted into the sample tube; the size of the ejection plate is larger than the inner diameter of the sample tube and smaller than the inner diameter of the sampling tube. When working, the ejection plate ejects the sample tube from the sampling tube.

[0022] In this embodiment, the sampling tube fixing sleeve is installed at the sampling tube joint when working. The sampling tube fixing sleeve 7 is a semicircular structure. A sampling tube connecting sleeve 8 is arranged on the base corresponding to the opposite side of the sampling tube fixing sleeve 7. The height of the sampling tube connecting sleeve is lower than that of the sampling tube fixing sleeve.

[0023] When the utility model is used, after the underwater vertical sediment sampler completes sampling, the extra-long sampling tube needs to be recovered in sections during the recovery process, and then the sample in the sampling tube is taken out. When sampling the sampling tube recovered in sections, the sample tube ejection module is installed at the sampling tube joint through the sampling tube fixing sleeve 7, and the sampling tube with the sample tube ejection module installed is placed on the sampling tube bracket, and the oil cylinder starts to work. First, the sample tube positioning plate is inserted into one end of the sample tube, and the sample tube ejection module is positioned, and then the oil cylinder is started, and the oil cylinder telescopic rod is extended, and the ejection plate ejects the sample tube together with the sample in the sample tube and drops it onto the sample tube bracket. The pulley on the sample tube bracket can help the sample tube slide forward to avoid damage to the sample tube and the sample due to poor movement after the sample tube falls on the sample tube bracket.

[0024] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
