Description

Technical Field

[0002] In solid mineral exploration, rock sampling is a crucial step, which provides key data for understanding geological structure, ore deposit properties, mineral composition and degree of mineralization. During the sampling process, sampling devices are needed to obtain rock samples at different depths.

[0003] The prior art has the following defects. On the one hand, different types of rocks have different physical properties, including hardness, particle size and structure. The vibration or impact force of the sampling device is too large, which is easy to produce more debris and dust. In addition, some rocks may contain clay or fine powder minerals, which may also increase the amount of dust generated, thereby reducing the protection of workers. On the other hand, the connection between some existing core drill bits and joints usually adopts a threaded design. If the threaded connection is over-tightened during installation, resulting in over-tightening of the threads, it may increase the difficulty of disassembly. Over-tightening may cause a tight bond between the threads, requiring more force to release the connection, and the threaded connection parts may be damaged or worn, which may cause the threads to fail or deform, thereby increasing the difficulty of disassembly. Therefore, a rock sampling device for solid mineral exploration is proposed to solve the above problems. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 3 The utility model provides an embodiment: a rock sampling device for solid mineral exploration, including a rotating rod 1, the top of the rotating rod 1 can be connected to an existing motor, so that the motor can drive the entire rotating rod 1 and a drill bit 9 to rotate and perform drilling sampling. The outer wall of the rotating rod 1 is in contact with a dust cover 2, and the dust cover 2 can move vertically on the outer wall of the rotating rod 1, and can also rotate along the outer wall of the rotating rod 1. The outer wall of the dust cover 2 is elastically connected to a cannula 4 through a reset spring 3, and the right end of the cannula 4 is rotatably connected to a ball 5, and the ball 5 is connected to the outer wall of the cannula 4 through the ball 5. The outer wall contact of the rotating rod 1 can reduce the friction between the rotating rod 1 and the dust cover 2, and can keep the position of the dust cover 2 unchanged when the rotating rod 1 rotates. The inner wall of the dust cover 2 is penetrated and fixedly connected with a nozzle 6. The nozzle 6 is an existing water mist spray, which can reduce the dust in the dust cover 2 and prevent the dust from diffusing to the outside. The outer wall of the nozzle 6 is provided with a conveying mechanism, and the bottom end of the rotating rod 1 is provided with a drill bit 9. The drill bit 9 is an existing core drill bit 9 technology, and the subsequent sampling process can be completed through the drill bit 9. This is the existing technology and will not be described in detail.

[0032] Reference Figure 4-Figure 5The top of the drill bit 9 is fixedly connected with an insert block 10, and the inner wall of the insert block 10 is penetrated and slidably connected with a pressing plate 11, and the pressing plate 11 is used to bring the card plate 13 to move horizontally. The pressing plate 11 is provided with two groups, and the two groups of pressing plates 11 are elastically connected by a positioning spring 12. One end of the positioning spring 12 is fixed to the left end pressing plate 11, and the other end positioning spring 12 is fixed to the right end pressing plate 11. When the pressing plates 11 are close to each other, the positioning spring 12 is compressed. When resetting, the pressing plates 11 are separated from each other by the elastic force of the positioning spring 12. The outer wall of the pressing plate 11 is fixedly connected with a card plate 13, and the card plate 13 is penetrated and slidably connected to the inner wall of the insert block 10. The insert block 10 is plugged into the inner wall of the rotating rod 1, and the card plate 13 is plugged into the inner wall of the rotating rod 1. The inner wall of the rotating rod 1 is provided with a notch corresponding to the card plate 13, which can allow the card plate 13 to be plugged into the rotating rod 1 to limit the entire drill bit 9.

[0033] Reference Figure 1-Figure 3 The outer wall of the dust cover 2 is fixedly connected to one end of the return spring 3. When the insert tube 4 moves to the left, the return spring 3 will be stretched. When resetting, the insert tube 4 is reset by the elastic force of the return spring 3. The other end of the return spring 3 is fixedly connected to the inner side wall of the insert tube 4. The insert tube 4 passes through and is slidably connected to the inner wall of the dust cover 2. The insert tube 4 is plugged into the outer wall of the rotating rod 1. The outer wall of the rotating rod 1 is provided with a plurality of notches corresponding to the insert tube 4, so that when the dust cover 2 is not in use, the insert tube 4 can be plugged into any one of the notches to limit the dust cover 2. The ball 5 contacts the outer wall of the rotating rod 1. The conveying mechanism includes a conveying pipe 7, which is composed of two pipes, which respectively convey water to the nozzle 6 for spraying. The conveying pipe 7 is arranged on the outer wall of the nozzle 6. The connecting end of the conveying pipe 7 is fixedly connected with a connecting pipe 8, which is connected to an external water tank. The water is conveyed to the conveying pipe 7 and the nozzle 6 through the connecting pipe 8 by the water pump in the water tank.

[0034] Working principle: First, when drilling and sampling is needed, just move the cannula 4 to the left and stretch the reset spring 3 to separate the cannula 4 from the notch on the upper outer wall of the rotating rod 1, then move the entire dust cover 2 to let the dust cover 2 move downward along the outer wall of the rotating rod 1, let the bottom end of the dust cover 2 contact the ground, then release the cannula 4 and use the reverse elastic force of the reset spring 3 to reset the cannula 4. Due to the notch on the outer wall of the lower end of the rotating rod 1, the cannula 4 is still in a stretched state at this time. At this time, the rotating rod 1 and the drill bit 9 are rotated by an external device. Due to the contact relationship between the dust cover 2 and the rotating rod 1, the position of the dust cover 2 can be guaranteed not to change. During the drilling and sampling process, the rotating rod 1 will slowly drill a hole downward along the middle part of the dust cover 2, and at the same time, the external water tank pump will be started to transfer water to the connecting pipe 8, so that the connecting pipe 8 will transport the water to the delivery pipe 7, and the delivery pipe 7 will distribute the water to the nozzle 6 for spraying, so that the nozzle 6 will spray in a water mist manner, which can reduce the dust in the dust cover 2.

[0035] After the drilling is completed, the entire dust cover 2 can be moved upward. When the insert tube 4 coincides with the groove on the upper outer wall of the rotating rod 1, the reverse elastic force of the reset spring 3 is used to reset the insert tube 4, so that the insert tube 4 is plugged into the groove on the upper outer wall of the rotating rod 1 to position the entire dust cover 2.

[0036] When the drill bit 9 needs to be disassembled, it is only necessary to press the plug block 10 to make the plug block 10 and the clamping plate 13 move closer to each other and compress the positioning spring 12, so that the clamping plate 13 is separated from the inner wall groove of the rotating rod 1, and then the plug block 10 is separated from the inner wall of the rotating rod 1. When a new drill bit 9 is subsequently installed, it is only necessary to first connect the plug block 10 with the rotating rod 1. When the clamping plate 13 coincides with the inner wall groove of the rotating rod 1, release the pressing plate 11 and use the reverse elastic force of the positioning spring 12 to restore the pressing plate 11 and the clamping plate 13, so that the clamping plate 13 is connected with the inner wall groove of the rotating rod 1 to limit the entire drill bit 9, thereby reducing the possible difficulties in the threaded disassembly method.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
