Description

TECHNICAL FIELD

[0001] The utility model relates to a mud taking device field, especially to a manual mud taking device capable of taking deep and thick soft soil layer thin mud. BACKGROUND

[0002] At present, with the vigorous development of coastal cities, the requirements of river dredging, environmental protection, construction and development, indoor geotechnical test often needs to be done, that is, soil mechanics analysis (natural water content, rock-soil state, mass density, liquid limit plastic limit, compression modulus and some related indexes) of thin mud. When the water content of deep and thick layer thin mud is very high, the mud cannot be taken out by the usual drilling sampling equipment or thin-walled soil sampler, and the sampling work cannot be completed.

[0003] The conventional mud taking barrel is filled when it is just inserted into the mud taking barrel, so the mud at the required depth cannot be taken.

[0004] Patent No. "201020286187.3" discloses a "flowing soft soil exploration and taking device", but the patent cannot take the required depth of mud, and the mud enters the exploration head in the early stage, so it cannot guarantee that the mud taken at the end is the required depth of mud UTILITY MODEL CONTENT

[0005] The utility model aims to provide a manual mud taking device capable of taking deep and thick soft soil layer thin mud.

[0006] The innovation of the utility model lies in that the mud taking device in the utility model can accurately take the mud at the required depth.

[0007] To achieve the above utility model purpose, the technical scheme of the utility model is as follows:

[0008] A manual mud taking device capable of taking deep and thick soft soil layer thin mud, comprising a guide rod, a mud loading barrel connected to the guide rod, the top and bottom of the mud loading barrel being open, a floating ball arranged in the mud loading barrel, the bottom opening size of the mud loading barrel being smaller than the cross-sectional size of the floating ball; a limiting piece arranged on the top of the mud loading barrel for limiting the floating ball in the mud loading barrel, a first pull rope arranged on the floating ball for pulling the floating ball, the first pull rope being pulled out from the bottom of the mud loading barrel.

[0009] Further, the guide rod is composed of a plurality of rod segments, and the plurality of rod segments are detachably connected. The depth can be flexibly adjusted.

[0010] Further, the plurality of rod segments are screw-connected. The disassembly and assembly speed is fast.

[0011] Further, a second pull rope is further arranged on the floating ball, and the second pull rope is pulled out from the top of the mud loading barrel. When the floating ball is stuck, the second pull rope can be pulled to pull up the floating ball.

[0012] Furthermore, both the No. 1 and No. 2 pull ropes are steel wire ropes.

[0013] Furthermore, the limiting component is a cross-shaped structure connected to the top of the mud-filling bucket, and the top dimension of the mud-filling bucket is larger than the cross-sectional dimension of the float. This ensures that the mud-filling bucket is not clogged during insertion, and that insertion resistance is low.

[0014] Furthermore, the mud-filling bucket is located near the bottom of the guide rod.

[0015] The beneficial effects of this utility model are:

[0016] 1. In this utility model, the buoyancy of the float in the soft mud is used so that the float is initially located at the top of the mud bucket. When it reaches the specified depth, the No. 1 pull rope is pulled, and the float squeezes the mud out of the mud bucket. The mud at the required depth flows into the mud bucket, and the bottom of the mud bucket is blocked by the float. It can be pulled out by the guide rod.

[0017] 2. In this utility model, the length of the guide rod can also be flexibly adjusted according to the insertion depth.

[0018] 3. In this invention, the second pull rope can also be used to give the float an upward pull, making the float less likely to get stuck. Attached Figure Description

[0020] Figure 2 This is a schematic diagram of the limiting component. Detailed Implementation

[0021] The technical solutions in the embodiments of this utility model will now be clearly and completely described with reference to the accompanying drawings.

[0022] Example 1: As Figure 1 , 2 As shown, an artificial mud-collecting device for obtaining thick soft soil layer sludge includes a guide rod 1, which is composed of several rod segments 1.1, which are detachably connected and spirally connected.

[0023] A mud-filling bucket 2 is connected to the guide rod 1. The top and bottom of the mud-filling bucket 2 are open. A float 3 is provided inside the mud-filling bucket 2. The bottom opening size of the mud-filling bucket 2 is smaller than the cross-sectional size of the float 3. A limiting member 5 is provided at the top of the mud-filling bucket 2 to limit the float 3 inside the mud-filling bucket 2. The limiting member 5 is a cross-shaped structure connected to the top of the mud-filling bucket 2. The top size of the mud-filling bucket 2 is larger than the cross-sectional size of the float 3.

[0024] The float ball 3 is provided with a first pull rope 4 for pulling the float ball 3, and the first pull rope 4 is pulled out from the bottom of the mud loading barrel 2. The float ball 3 is also provided with a second pull rope 6, and the second pull rope 6 is pulled out from the top of the mud loading barrel 2. The first pull rope 4 and the second pull rope 6 are both steel wires.

[0025] When working, the mud taking device is inserted into the mud, the float ball 3 floats up in the soft mud, so that the float ball is initially located at the top of the mud loading barrel 2, when reaching the specified depth, the first pull rope 4 is pulled, the float ball 3 extrudes the mud in the mud loading barrel 2, the mud at the required depth flows into the mud loading barrel 2, and the bottom of the mud loading barrel 2 is blocked by the float ball 3, and the mud loading barrel 2 is pulled out through the guide rod.
