Description

Technical Field

[0001] The present application relates to the technical field of geological exploration, and in particular to a solid mineral sampling device for geological exploration. Background Art

[0002] Geological exploration sampling refers to the process of collecting geological samples from the surface or underground for analysis and research during geological exploration. The purpose is to obtain information about geological structure, geological composition, underground resource distribution, etc., in order to carry out geological surveys, resource evaluation, mineral exploration and other work.

[0003] In the process of sampling underground solid mineral samples, the sampling equipment will exert a certain force and vibration when scraping in the drilled hole, which can easily cause damage to the soil structure above the scraping position. Especially in strata that are prone to collapse, such as loose soil or sandstone, the vibration during the scraping process will make the soil layer unstable, causing the soil at different depths to fall or even collapse. Utility Model Content

[0004] In view of this, the purpose of the utility model is to solve the shortcomings existing in the background technology and to propose a solid mineral sampling equipment for geological exploration to solve the problems existing in the prior art.

[0006] Preferably, the push-against protection mechanism includes a slot provided on a fixed frame, the inner wall of the slot is slidably connected with a shift push rod, and there are five groups of shift push rods. The push-against protection mechanism cooperates with the driving mechanism to enable the arc-shaped support plate to be supported against the inner wall of the underground borehole, thereby reducing the probability of soil layer collapse during the sampling process.

[0007] Preferably, an arc-shaped supporting plate is provided at one end of the shift push rod away from the fixed frame, and a guide shaft is fixedly connected to the upper surface of the arc-shaped supporting plate. An end block is provided on the top of the guide shaft. Five groups of arc-shaped supporting plates are provided, and the same number of corresponding shift push rods and other components are also provided.

[0008] Preferably, the outer surface of the straight rod is rotatably connected to a transmission gear, and a plurality of guide arc holes are opened on the outer surface of the transmission gear. The inner walls of the guide arc holes are slidably connected to the outer surface of the guide shaft, and the guide arc holes have the effect of limiting the driving of the guide shaft.

[0009] Preferably, the driving mechanism comprises a motor fixedly mounted on the top of the fixing frame, the output end of the motor is fixedly connected with a driving gear, and the outer surface of the driving gear is meshingly connected with the outer surface of the transmission gear.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. The solid mineral sampling equipment for geological exploration can perform pressure protection on the inner wall of the hole through the driving mechanism and the push-pull protection mechanism, effectively reducing the impact of vibration on the soil structure, maintaining the stability of the soil layer above the sampling site, and reducing the risk of loosening and collapse of the soil layer.

[0012] 2. The solid mineral sampling equipment for geological exploration has an inclined sampling shovel that can maintain the stability of sample scraping and reduce the chance of sample leakage. At the same time, it ensures that the sampling equipment can scrape more samples and accurately collect target mineral samples, thereby improving the accuracy and representativeness of sampling.

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] See also Figure 1-3 A solid mineral sampling device for geological exploration includes a straight rod 1, the bottom of the straight rod 1 is fixedly connected to a chassis 2, the outer surface of the chassis 2 is provided with a plurality of sampling shovels 3, the outer surface of the straight rod 1 is rotatably connected to a fixing frame 4, the fixing frame 4 is provided with a pushing and protecting mechanism for abutting against the inner side of the hole wall to maintain the stability of the soil layer, and the fixing frame 4 is provided with a driving mechanism.

[0019] Through the above technical solution, when the device is in use, the device is inserted deep into the underground hole after drilling. Through the driving mechanism and the pushing and resisting protection mechanism, the five groups of arc-shaped supporting plates 7 can be moved outward synchronously until they are against the inner wall of the hole. Finally, the straight rod 1 can be rotated to make the three groups of inclined sampling shovels 3 rotate at the same time, thereby scraping the sample.

[0020] Specifically, the push protection mechanism includes a slot 5 formed on the fixing frame 4, and the inner wall of the slot 5 is slidably connected with a displacement push rod 6, and the number of the displacement push rod 6 is five groups.

[0021] Through the above technical solution, the five groups of displacement push rods 6 are evenly distributed on the fixing frame 4 , and they are displaced synchronously during the process of sliding and pushing outward along the slot 5 .

[0022] Specifically, an arc-shaped abutment plate 7 is provided at one end of the displacement push rod 6 away from the fixed frame 4 , a guide shaft 8 is fixedly connected to the upper surface of the arc-shaped abutment plate 7 , and an end block 9 is provided on the top of the guide shaft 8 .

[0023] Through the above technical solution, the arc-shaped design of the arc-shaped supporting plate 7 is compatible with the cross-sectional shape of the drill shaft of the drilling rig, and the end block 9 plays a limiting role to maintain the overall stability of the movement of the guide shaft 8.

[0024] Specifically, the outer surface of the straight rod 1 is rotatably connected to a transmission gear 10 , and the outer surface of the transmission gear 10 is provided with a plurality of guide arc holes 11 , and the inner walls of the guide arc holes 11 are slidably connected to the outer surface of the guide shaft 8 .

[0025] Through the above technical solution, five groups of guide arc holes 11 are provided, which respectively correspond to the corresponding guide shafts 8 .

[0026] Specifically, the driving mechanism includes a motor 12 fixedly mounted on the top of the fixing frame 4 , an output end of the motor 12 is fixedly connected with a driving gear 13 , and an outer surface of the driving gear 13 is meshedly connected with an outer surface of the transmission gear 10 .

[0027] Through the above technical solution, the driving gear 13 drives the transmission gear 10 to rotate during the rotation process. Under normal circumstances, when the straight rod 1 is rotated, the transmission gear 10 will not rotate synchronously with the straight rod 1 due to the limitation of the driving gear 13.

[0028] Working principle: When the device is in use, the whole device is first inserted into the underground hole after drilling until the bottom plate 2 contacts the bottom wall of the hole. At this time, in order to keep the soil layer above the sampling site stable, the motor 12 can be turned on to drive the driving gear 13 to rotate. The driving gear 13 will drive the transmission gear 10 meshing with it to rotate. During the rotation of the transmission gear 10, the position of the guide arc hole 11 will change accordingly, and the guide shaft 8 will rotate along the guide arc hole 11. As the guide arc hole 11 and the guide shaft 8 slide, the shift push rod 6 will be driven, so that the shift push rod 6 on the fixed frame 4 will slide synchronously along the corresponding slot 5 to the outside. At this time, the arc-shaped supporting plate 7 at the end of the displacement push rod 6 will move outward at the same time until the five groups of arc-shaped supporting plates 7 are completely against the inner wall of the hole, thereby protecting the protrusion of the inner wall of the hole from pressure. Finally, the rotatable straight rod 1 drives the chassis 2 to rotate, and the three groups of inclined sampling shovels 3 on the chassis 2 can scrape the mineral samples on the soil layer. Through the pressure protection of the inner wall of the hole, the influence of vibration on the soil layer structure is effectively reduced, the stability of the soil layer above the sampling position is maintained, and the risk of loosening and collapse of the soil layer is reduced. Keeping the soil layer stable can ensure that the sampling equipment can accurately collect the target mineral samples when scraping the samples, thereby improving the accuracy and representativeness of the sampling.

[0029] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
