Description

Technical Field

[0001] The utility model belongs to the technical field of geological and mineral exploration, in particular to a sampling and excavation device for geological exploration. Background Art

[0002] Geological and mineral exploration is based on advanced geological science theories. On the basis of a large amount of field geological observations and the collection and collation of relevant geological data, it uses comprehensive geological means and methods such as geological surveying, geophysical and geochemical exploration, and drilling and exploration projects to obtain reliable geological and mineral information. After searching, the patent with application number 202020420867.3 discloses a sampling device for geological and mineral exploration, including a shell and a fixed plate. A limiting sleeve is connected to the middle of the bottom end of the shell. A circular fixing hole is drilled in the middle of the fixing plate. The limiting sleeve is nested in the corresponding fixing hole. Four groups of bottom columns are welded to the four corners of the bottom end of the fixing plate. A threaded hole is drilled in the bottom of the bottom column. A screw is rotatably connected to the threaded hole.

[0003] However, during actual use, the applicant found that dust would be generated during the geological exploration sampling and excavation process. The dust would adhere to the heat dissipation window on the outer shell of the motor, and the filter window at the heat dissipation window could not be removed, making it difficult to thoroughly clean the dust on the filter window. This would hinder the ventilation efficiency inside the shell and prevent the motor from dissipating heat smoothly. In view of this, we proposed a sampling and excavation device for geological exploration. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-3 As shown, the utility model provides a technical solution:

[0021] A sampling and excavation device for geological exploration includes a chassis 1, a motor 7 is fixedly installed inside the chassis 1, a battery pack is provided inside the chassis 1 for powering the motor 7, and an on-off switch of the motor 7 is provided on the chassis 1, which will not be described in detail here. Heat dissipation windows 11 are symmetrically provided on the chassis 1 on the front and rear sides of the motor 7, and handles 2 are symmetrically fixedly connected to the two sides of the chassis 1. A handle glove 21 is fixedly sleeved on the middle part of the handle 2. The setting of the handle glove 21 is used to increase the friction between the personnel's hand and the handle 2 and make the personnel more comfortable when holding the handle 2. The rotating end of the motor 7 is fixedly connected to the drill rod 6 through a coupling, and the lower end of the drill rod 6 is fixedly connected to the sampling barrel 4. The lower end of the sampling barrel 4 is evenly provided with drill teeth. The bottom of the chassis 1 is fixedly connected to a splash shield 3, through The splash shield 3 is set up to prevent flying soil and rocks from causing injuries to the operator's head during geological exploration sampling and excavation, which is safer. When conducting geological exploration sampling and excavation, two operators can stand on both sides of the chassis 1 respectively, and manually hold the handles 2 on both sides respectively, and place the lower end of the sampling tube 4 on the ground where the sampling is required, and drive the motor 7 to rotate. The rotation of the motor 7 can drive the drill rod 6 to rotate, and the rotation of the drill rod 6 can drive the sampling tube 4 to rotate. At the same time, the sampling tube 4 can be manually pressed downward to screw the sampling tube 4 into the ground, so that geological exploration sampling can be carried out through the sampling tube 4. The flying soil and rocks caused by the rotation of the sampling tube 4 can be blocked by the splash shield 3 to prevent the flying soil and rocks from causing injuries to the operator's head.

[0022] The filter window 5 is inserted in the position of the heat dissipation window 11 on the top of the chassis 1, and an insertion slot 12 is provided at the position of the heat dissipation window 11 on the top of the chassis 1. The filter window 5 is inserted in the insertion slot 12. The center position of the top of the chassis 1 is rotatably connected with a rotating shaft 8 through a bearing. The lower end of the rotating shaft 8 is elastically connected to the chassis 1 through a torsion spring. A blocking arm 9 is sleeved and fixed on the rotating shaft 8. The bottom of the blocking arm 9 slides along the top of the chassis 1, and the two ends of the blocking arm 9 respectively abut against the top of the two filter windows 5. By rotating the rotating shaft 8, the blocking arm 9 is driven to rotate so that the end of the blocking arm 9 is removed from the top of the filter window 5, and the filter window 5 can be pulled out from the insertion slot 12, and the dust attached to the filter window 5 can be thoroughly cleaned, thereby better ensuring efficient ventilation at the heat dissipation window 11 and enabling the motor 7 to dissipate heat smoothly. The upper end of the rotating shaft 8 is sleeved and fixed with a handle 10. When dust is collected on the filter window 5, the dust on the filter window 5 will adhere to the filter window 5. When the dust collected on the filter window 5 is too much and affects the internal ventilation and heat dissipation of the chassis 1, the handle 10 can be manually rotated clockwise to drive the rotating shaft 8 to rotate together with the blocking arm 9. The blocking arm 9 can rotate so that its two ends are moved away from above the two filter windows 5. At this time, the personnel can pull out the two filter windows 5 from their insertion slots 12 and thoroughly clean the dust on the filter windows 5. After cleaning, the handle 10 can be manually rotated clockwise again to drive the rotating shaft 8 and the blocking arm 9 to rotate. At this time, the rotation of the rotating shaft 8 can compress the torsion spring, and then the two filter windows 5 are inserted into the two insertion slots 12 one by one, and the handle 10 is released. At this time, under the elastic force of the torsion spring, the rotating shaft 8 will be driven to return to rotation, thereby driving the blocking arm 9 to return to rotation, so that the two ends of the blocking arm 9 are respectively moved to above the two filter windows 5, so that the two filter windows 5 can be quickly limited.

[0023] Working principle: During use, when conducting geological survey sampling and excavation, two operators can stand on both sides of the chassis 1 respectively, and manually hold the handles 2 on both sides respectively, and place the lower end of the sampling tube 4 on the ground where the sampling is required, and drive the motor 7 to rotate. The rotation of the motor 7 can drive the drill rod 6 to rotate, and the rotation of the drill rod 6 can drive the sampling tube 4 to rotate. At the same time, the sampling tube 4 can be pressed down manually to screw the sampling tube 4 into the ground, so that geological survey sampling can be carried out through the sampling tube 4. The splashing soil and rocks caused by the rotation of the sampling tube 4 can be blocked by the splash shield 3 to prevent the splashing soil and rocks from causing injuries to the operator's head. The dust generated during the geological survey sampling process will adhere to the filter window 5. When there is a lot of dust attached to the surface of the filter window 5, it will affect the interior of the chassis 1. When the interior is ventilated and heat dissipated, the handle 10 can be manually rotated clockwise to drive the rotating shaft 8 to rotate together with the blocking arm 9. The rotation of the blocking arm 9 can move its two ends away from above the two filter windows 5. At this time, the personnel can pull out the two filter windows 5 from their insertion slots 12 and thoroughly clean the dust on the filter windows 5. After cleaning, the handle 10 is manually rotated clockwise again to drive the rotating shaft 8 and the blocking arm 9 to rotate. At this time, the rotation of the rotating shaft 8 can compress the torsion spring, and then the two filter windows 5 are inserted into the two insertion slots 12 one by one, and the handle 10 is released. At this time, under the action of the elastic force of the torsion spring, the rotating shaft 8 will be driven to reset and rotate, thereby driving the blocking arm 9 to reset and rotate, so that the two ends of the blocking arm 9 are respectively moved to above the two filter windows 5, and the two filter windows 5 can be quickly limited.
