Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sampling devices, in particular to a coal mine geological sampling device. Background Art
[0002] Coal geological sampling is a crucial step in the exploration and mining process. It involves collecting representative samples from the coal ore body for subsequent analysis, testing, or identification. The goal is to understand the coal's composition, properties, processing performance, and industrial value. By sampling and analyzing the coal's composition (such as combustible materials, non-combustible materials, and harmful impurities) and characteristics, the coal type and industrial grade are determined. Evaluating the industrial value of coal provides basic data for its processing, utilization, sales, and environmental assessment.
[0003] However, in the prior art, such coal mine geological sampling devices, such as the Chinese patent application No. 202220772393.8, are used for coal mine geological sampling devices. Coal mine samples are sampled by an auger that rises and falls and rotates. However, after sampling, the samples are taken out and directly transferred to the aggregate bucket. However, when the auger rotates, the geological material just transported up may not be the required sampling depth, and the surface geological soil will also be transported to the aggregate bucket. In this way, there is no separation structure, resulting in poor sampling effect of the device. Therefore, an improved coal mine geological sampling device is needed to address this problem. Utility Model Content
[0004] The purpose of the utility model is to provide a coal mine geological sampling device to solve the problems raised in the above background technology.
[0005] The cam is secured to the upper portion of the frame by an L-shaped latch, and the lower portion of the L-shaped latch is secured to the lower portion of the frame by an L-shaped latch.
[0006] Preferably, a first discharge port is provided on one side of the lower end of the separation bin, and a second discharge port is provided on the side of the lower end of the separation bin away from the first discharge port. Through the two discharge ports, the soil layer transported out before the auger is inserted into the target depth can be discharged from the first discharge port, and after the auger is inserted into the target depth, the second auger is reversed, so that the soil layer at this time can be discharged from the second discharge port. In this way, the soil layer discharged by the first auger can be automatically separated, thereby achieving a better sampling effect.
[0007] Preferably, a second motor is fixedly provided on one side of the surface of the separation bin, and the second motor is transmission-connected to the rotating shaft where the second auger is located, so that the second auger can be driven to rotate by the second motor.
[0008] Preferably, an electric push rod is fixedly provided on the upper end of the fixed frame, and a connecting plate is fixedly provided on the upper end of the sliding rod. The movable end of the electric push rod is fixedly connected to the connecting plate. The sliding rod and all structures fixedly connected to the sliding rod can be driven up and down by the extension and retraction of the electric push rod, so that the first dragon can be inserted into the soil layer, so that sampling work can be carried out.
[0009] Preferably, a roller is movably provided on one side of the lower end of the fixed frame via a rotating shaft, and the roller can facilitate the movement of the entire pushing device.
[0010] Preferably, a filter plate is movably provided on one side of the surface of the fixed frame, and the filter plate can be installed as needed. The filter plate of this device is fastened to the fixed frame by interference fit, and the filter plate can be installed when oversampling samples needs to be filtered, so that only small samples can enter the separation chamber.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] 1. The utility model utilizes the continuously rotating first auger to transport the sample to the sampling tube and the upper end of the fixed frame. Then the sample can slide from the fixed frame into the separation chamber. At this time, the device has two discharge ports. Before the auger is inserted into the target depth, the soil layer transported out can be discharged from the first discharge port. After the auger is inserted into the target depth, the second auger is reversed, and the soil layer at this time can be discharged from the second discharge port. In this way, the soil layer discharged by the first auger can be automatically separated, thereby achieving a better sampling effect.
[0013] 2. When using the utility model, the filter plate can be installed as needed. The filter plate is fitted on the fixed frame with interference fit. When oversampling samples need to be filtered, the filter plate can be installed. In this way, only small samples can enter the separation chamber, thereby eliminating the need for subsequent sample sorting. BRIEF DESCRIPTION OF THE DRAWINGS

The device has two discharge ports. When the auger is inserted into the target depth, the soil layer transported out can be discharged from the first discharge port 11. When the auger is inserted into the target depth, the second auger 10 is reversed, and the soil layer at this time can be discharged from the second discharge port 12.
