AI Technical Summary
When exploring for rocks and minerals, backpack drills have difficulty ensuring that the drill rod is perpendicular to the horizontal plane, especially when operating on steep rocks, where the drill rod is prone to tilting, affecting drilling accuracy.
A mineral exploration sampling device was designed. By setting a ball head and a counterweight rod on the support plate, the state of the alignment rod can be observed through the observation hole to determine whether the drill rod is perpendicular to the horizontal plane. The counterweight rod is used to assist in correcting the position of the drill rod.
It improves the accuracy of drill pipe verticality judgment, avoids drill pipe deflection, and enhances drilling accuracy.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of sampling device technology, and in particular to a mineral exploration sampling device. Background Technology
[0002] When exploring for rocks and minerals, it is necessary to drill core samples from the rocks. For rocks with uneven surfaces, large drilling rigs are difficult to install stably. Therefore, backpack drills are often used to drill cores. Backpack drills can be operated by a single person, and their structure can be referenced in patent document CN207231819U. When manually operating a backpack drill, one can only judge whether the drill rod is perpendicular to the horizontal plane by feel. Especially when operating the drill on steep rocks, errors in judgment often lead to the drill rod tilting, which requires improvement. Utility Model Content
[0003] To address the problems mentioned in the background art, the purpose of this utility model is to provide a mineral exploration and sampling device.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows:
[0005] A mineral exploration sampling device includes a base with handles on both sides. A motor is vertically mounted on the top of the base, and a drill rod is detachably connected to the motor's spindle. A support plate is mounted on the base above the motor, with a lower limiting ring fixed to the support plate and an upper limiting ring fixed to the top of the lower limiting ring. The inner walls of both the lower and upper limiting rings are spherical. A ball head is fitted between the lower and upper limiting rings, with the center of the ball head located on the axis of the drill rod. An alignment rod is fixed to the top of the ball head, and a counterweight rod is fixed to the bottom of the ball head. A through hole for the counterweight rod to move is provided on the support plate. The alignment rod and the counterweight rod are coaxially arranged. A shielding plate is horizontally arranged on the support plate above the alignment rod, and an observation hole is provided on the shielding plate corresponding to the position of the alignment rod. When the drill rod and the alignment rod are coaxial, the top of the alignment rod can be fully observed by the human eye through the observation hole.
[0006] Furthermore, the base is provided with several lower columns on its top, and the support plate is fixed to the top of the lower columns.
[0007] Furthermore, the top of the support plate is provided with several upper columns, and the shielding plate is fixed to the top of the several upper columns.
[0008] Furthermore, the length and radius of the counterweight rod are both greater than those of the alignment rod.
[0009] The beneficial effects of this utility model are: the state of the alignment rod can be viewed through the observation hole to determine whether the drill rod is perpendicular to the horizontal plane, which effectively improves the accuracy of the judgment and avoids the drill rod from deviating.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.
[0014] like Figures 1-2 As shown, a mineral exploration sampling device includes a base 1, with handles 11 on both the left and right sides of the base 1. A motor 2 is vertically mounted on the top of the base 1, and a drill rod 3 is detachably connected to the main shaft of the motor 2. Four lower columns 12 are vertically mounted on the top of the base 1, and a support plate 13 is mounted on the top of the four lower columns 12. The support plate 13 is horizontally positioned above the motor 2. A lower limit ring 4 is fixedly connected to the top surface of the support plate 13, and an upper limit ring 5 is fixedly connected to the top of the lower limit ring 4 by screws (not shown in the figure). The inner walls of both the lower limit ring 4 and the upper limit ring 5 are spherical. A ball head 6 is fitted between the lower limit ring 4 and the upper limit ring 5, with the center of the ball head 6 located on the axis of the drill rod 3. The top of the ball head 6 is fixedly connected to an alignment rod 62, and the bottom of the ball head 6 is fixedly connected to a counterweight rod 61. The support plate 13 has a through hole 131 for the counterweight rod 61 to move. The alignment rod 62 and the counterweight rod 61 are coaxially arranged. The length and radius of the counterweight rod 61 are both greater than those of the alignment rod 62. Two upper columns 14 are vertically arranged on the top of the support plate 13. A baffle plate 15 is fixedly connected to the top of the two upper columns 14. The baffle plate 15 is horizontally arranged. An observation hole 151 is opened on the baffle plate 15 corresponding to the position of the alignment rod 62. The radius of the observation hole 151 is 0.5 cm larger than the radius of the alignment rod 62. When the drill rod 3 is coaxial with the alignment rod 62, the top of the alignment rod 62 can be completely observed by the human eye through the observation hole 151.
[0015] When drilling into the rock, the worker holds the handle 11 with both hands and lets the drill rod 3 touch the rock. The worker looks down and observes the state of the alignment rod 62 through the observation hole 151. If the top of the alignment rod 62 can be fully observed, it means that the drill rod 3 is perpendicular to the horizontal plane, or the drill rod 3 has only a very small deflection angle. If the top of the alignment rod 62 cannot be fully observed through the observation hole 151, it means that the deflection angle of the drill rod 3 is too large and needs to be adjusted.
[0016] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
