Description

Technical Field

[0001] The invention relates to the technical field of geological exploration, in particular to an electric rotary sampler used for geological exploration. Background Art

[0002] Geological exploration is the work of investigating and detecting geological conditions through various means and methods, the main purpose of which is to find out the underground geological structure, mineral resources, rock and soil characteristics and other information;

[0003] When conducting geological exploration, an electric rotary sampler is required. A geological exploration sampler is a tool specifically used to obtain samples from the soil. These samples are crucial for understanding many aspects of underground geological structure.

[0004] The current samplers still have the following deficiencies:

[0005] 1. When using some common electric rotary samplers, the sampling operation is usually completed by driving the sampling tube to rotate and move downward. However, in this process, the stability of the sampling tube in the rotating downward stage is poor, which can easily cause the sampler to shake, affecting the sampling work;

[0006] 2. When using some common electric rotary samplers, after the sampling is completed using the sampling tube, the soil in the sample tube needs to be taken out. This operation is not only time-consuming but also laborious, which greatly increases the difficulty of sampling work and seriously affects the efficiency of sampling work;

[0007] 3. When some existing common electric rotary samplers are in use, usually, two motors are required for their operation, one of which is responsible for driving the sampling tube to rotate, and the other is used to drive the sampling tube to move downward. Dual motors mean more parts and a more complex circuit system. This dual-motor mode will increase the failure rate of the sampler when in use. Summary of the invention

[0022] The present invention provides an electric rotary sampler for geological exploration, which has the following beneficial effects:

[0023] The electric rotary sampler for geological exploration uses a height adjustment component. When the electric rotary sampler is used, a reduction motor is started to drive a threaded rod and a large gear to rotate. The threaded rod drives a moving plate, a first connecting rod, a hexagonal barrel, a first small bevel gear, an L-shaped mounting plate, a second connecting rod, a second small bevel gear, a third small bevel gear, a rotating tube and a large bevel gear to move downward. At the same time, the large gear drives the second small gear, a transmission rod and a first small gear to rotate. The transmission rod drives the first small bevel gear, the first connecting rod and the hexagonal barrel to rotate through the large bevel gear, the third small bevel gear, the second connecting rod and the second small bevel gear. The sampling component can be driven to rotate and move downward through the hexagonal barrel, so that the failure rate of the sampler when in use can be reduced.

[0024] The electric rotary sampler for geological exploration uses a limit assembly. When the electric rotary sampler is used, a synchronizer is used to control two second electric push rods to start simultaneously. The two second electric push rods drive the corresponding arc blocks, U-shaped support blocks, support wheels and scrapers to move. The second electric push rods are self-locking, so that a plurality of support wheels clamp the sampling assembly, which can improve the stability of the sampling assembly when it rotates and moves downward, thereby improving the stability of the sampler when in use.

[0025] The electric rotary sampler for geological exploration uses a sampling component. When the electric rotary sampler is used, after the sampling component finishes sampling, the screws connecting the arc plate and the convex ring are removed, and then the convex ring is rotated 180 degrees, and then the arc plate is moved upward to separate the arc plate from the sampling tube, so as to facilitate the subsequent removal of soil in the sampling tube, facilitate sampling work, and improve the convenience of using the sampler.

[0026] The electric rotary sampler for geological exploration uses a moving component. When the electric rotary sampler is used and the sampler needs to be moved, a synchronizer is used to control two first electric push rods to start simultaneously, driving a bottom plate to move upward, and then the sampler can be moved to a use location through four universal wheels at the bottom of the U-shaped plate. Then, a synchronizer is used to control the two first electric push rods to start simultaneously, and the two first electric push rods drive the corresponding bottom plates to move downward and contact the ground. The first electric push rods are self-locking, so that the sampler can be moved easily, thereby improving the convenience of using the sampler.

[0027] The electric rotary sampler for geological exploration uses a scraper and a cleaning component. When the electric rotary sampler is used, when the reduction motor is started to perform sampling, the threaded rod, the large gear, the second small gear, the transmission rod, the first small gear and the toothed belt drive the third small gear, the third connecting rod and the cleaning roller to rotate. The brush on the cleaning roller can clean the surface of the sampling component, and the scraper can scrape the soil attached to the surface of the sampling component. After the sampling tube is used, there is no need to clean the surface of the sampling tube separately, thereby improving the convenience of the sampler when used. BRIEF DESCRIPTION OF THE DRAWINGS
