Description

Technical Field

[0001] The utility model is applicable to the technical field of river channel dam soil quality detection, and particularly relates to a river channel dam soil quality collection device. Background Art

[0002] At present, the collection and processing of soil samples is an important prerequisite for the accuracy of soil testing data. The river dams of water conservancy may have loose soil due to long-term water erosion, which poses a major safety hazard. Therefore, regular dam soil sampling and analysis is required to ensure dam safety.

[0003] However, nowadays, when sampling the soil on the surface of the water conservancy river dam, it is necessary to use a corresponding sampling tube to drill holes in the corresponding position of the dam for sampling. In this process, the operator needs to support the driving mechanism for a long time. However, since the side of the dam is inclined, there is no corresponding support mechanism outside the driving mechanism for drilling sampling, which results in a large amount of labor consumption for the operator to support it manually, and the stability is insufficient, which affects the sampling quality. Therefore, we propose a soil sampling device for river dams. Utility Model Content

[0004] The main purpose of the utility model is to provide a river dam soil collection device, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A river dam soil collection device comprises a mounting plate, both ends of the side surface of the mounting plate are fixedly mounted with connecting plates, a fixing screw is rotatably installed between the inner sides of two groups of the connecting plates, a support plate is fixedly sleeved on the outer surface of the middle end of the fixing screw, and both ends of the outer surface of the fixing screw are screwed with limit nuts through threads;

[0007] The bottom surface of the outer side of the support plate is slidably sleeved with a support frame, the bottom surface of the support plate is fixedly mounted with a sliding plate, and the sliding plate is slidably mounted inside the support frame, the outer side of the support frame is movably plugged with a limiting bolt, both ends of the outer side of the sliding plate are provided with limiting screw holes, and the side edges of the limiting bolts are screwed into the limiting screw holes through threads;

[0008] A fixing plate is hingedly connected to the bottom of the support frame through a rotating shaft, and a floor is movably installed on the outer side of the bottom of the fixing plate.

[0009] By adopting the above technical solution, the positions of the support plate and the support frame are adjusted by fixing the screws, and the support frame is slidably sleeved on the outside of the support plate. The overall length and support inclination of the support plate and the support frame can be adjusted according to the inclination of the dam slope to be sampled, thereby ensuring that the floor surface at the bottom of the support frame can always fit the dam slope, providing the corresponding grip to the stability required for the operation of the entire drilling sampling mechanism, and reducing the labor consumption required by the operator for the hand support.

[0010] As an optional solution to the technical solution of the present application, a mounting frame is fixedly installed on the top surface of the mounting plate, a drilling driver is fixedly installed on the inner bottom surface of the mounting frame, a connecting piece is fixedly installed on the bottom surface of the driving shaft of the drilling driver, a mounting groove is opened inside the middle end of the mounting plate, and a sampling tube is detachably installed on the bottom of the connecting piece.

[0011] By adopting the above technical solution, the power required for the entire sampling drilling process is achieved through the structural action of the drilling driver.

[0012] As an optional solution of the technical solution of the present application, adjusting bolts are threadedly inserted on both sides of the top of the fixing plate, and the bottom of the adjusting bolts is rotatably installed inside the top of the floor panel through bearings.

[0013] By adopting the above technical solution, the pointed cone rod close to the bottom of the floor can be inserted into the soil of the dam by adjusting the structural action of the bolt, so that the position of the entire device can be reinforced.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. A river dam soil sampling device according to the technical solution of the present application, wherein a support plate is rotatably installed on the side of the mounting plate by fixing a screw rod, so that the support plate and the support frame can adjust the inclination angle on the side of the mounting plate, and then the support can be adjusted according to the inclination of the dam slope to be sampled, and then the support frame is slidably sleeved on the outside of the support plate, so that the support frame can be vertically moved on the outside of the support plate, and then the overall length of the support plate and the support frame can be adjusted according to the inclination of the dam slope to be sampled, thereby ensuring that the floor surface at the bottom of the support frame can always fit the dam slope, providing corresponding gripping force to the stability required for the operation of the entire drilling sampling mechanism, and reducing the labor consumption required by the operator for its hand support.

[0016] 2. A river embankment soil sampling device according to the technical solution of the present application can movably adjust the floor plate and the fixed plate by adjusting the bolts, so that after the adjusting bolts are turned, the floor plate can be driven to move vertically so that its bottom fits the embankment surface, and then the pointed cone rod at the bottom of the floor plate can be inserted into the soil on the embankment surface, thereby improving the stability of the support for the drilling drive machine.
