Chinese utility model patent, authorized announcement number "CN216926138U", discloses a deep and shallow stratified sampling device for mineral exploration engineering. This device uses a sampling box to collect soil samples, and the amount of soil samples collected is relatively large, which is convenient for testing. Two sampling slots of different heights are opened on one side of the sampling drill bit, so the position of the sampling box is set according to the position of the sampling slots. In this way, soil samples of different depths are stored in the two sampling boxes, which can perform stratified sampling of soil or rock layers at different depths.

[0003] During the use of the above-mentioned technical solutions, the high-speed rotating saw teeth of the drill bit will throw rock cuttings and ore fragments radially when cutting rock strata, forming a large amount of splash material. Some of the splash fragments contain valuable samples, resulting in sample loss. Repeated sampling is required to ensure analytical accuracy, which increases the operation time and cost. At the same time, the splash material may hit operators or equipment, causing safety accidents, especially in narrow tunnels or high-altitude operation scenarios where the risk is even higher. Therefore, we propose a rapid sampling prospecting drill bit device. Utility Model Content

[0020] Sampling drill 1: As the core drilling component, its bottom end is fixedly connected to the drilling teeth 11, and it cuts into the ore layer through high-speed rotation to achieve sampling; the internal feed trough 15 provides installation space for the spiral guide blade 16 to realize continuous transport of ore samples; the external rotating sleeve is connected to the positioning disk 4 to form a relative rotating structure to drive the drilling action.

[0021] Splash-proof positioning cylinder 2: It is slidably sleeved on the outside of the sampling drill bit 1. Its bottom has a positioning groove 10 to be embedded in the surface of the mineral layer, fixes the position of the device and supports the splash-proof structure; the top is slidably connected to the arc plate 5 through the slide rod 3 to ensure that it can slide freely with the drilling depth and block the splash of slag.

[0022] Slide rod 3: It is fixedly connected to the top of the splash-proof positioning cylinder 2 and slides with the through hole 17 of the arc plate 5 to realize the guiding sliding of the splash-proof positioning cylinder 2; a limit ring 6 is installed on the outer surface to prevent it from falling off during the sliding process.

[0023] Positioning disc 4: Rotatably sleeved on the outside of sampling drill 1, with a transmission groove 14 inside to accommodate the meshing transmission of gear 12 and gear ring 13; a handle 8 is fixedly connected to the outer surface for the operator to hold, and a protective cover 7 is installed to protect the internal transmission components.

[0024] Arc plate 5: It is fixedly connected to the outer surface of the positioning plate 4. Three through holes 17 are opened at the top and slidably connected to the slide rod 3 to provide sliding support for the splash-proof positioning cylinder 2. At the same time, the sliding range is limited by the limiting ring 6.

[0025] Limiting ring 6: It is fixedly connected to the outer surface of the slide rod 3 and located above the arc plate 5. It prevents the slide rod 3 from slipping out of the through hole 17 by physical blocking, and ensures the connection stability between the splash-proof positioning cylinder 2 and the positioning plate 4.

[0026] Protective cover 7: Fixedly connected to the outer surface of the positioning disk 4, covering the drive motor 9 and transmission components, preventing dust or slag from splashing onto critical components during drilling, extending equipment life and improving operational safety.

[0027] Handle 8: Fixedly connected to the outer surface of positioning disk 4, providing the operator with a hand-held force point, making it easy to align the control device with the surface of the ore layer and adjust the drilling angle.

[0028] Drive motor 9: Fixedly installed at the bottom of positioning disk 4, its output end extends into the transmission groove 14 and connects to gear 12. It converts electrical energy into mechanical energy to drive gear 12 to rotate, providing power for drilling.

[0029] Positioning groove 10: It is opened at the bottom of the splash-proof positioning cylinder 2. It is embedded in the surface of the mineral layer through a sharp groove structure, which enhances the friction between the device and the mineral layer, prevents displacement or swinging during drilling, and improves the fixing effect.

[0030] Drilling tooth 11: Fixedly connected to the bottom end of sampling drill bit 1, made of high-hardness alloy material, it cuts into the ore layer through high-speed rotation, breaks the rock and forms a sampling channel, and is a key component that directly performs drilling operations.

[0031] Gear 12: Fixedly connected to the output end of the drive motor 9, located inside the transmission groove 14, meshing with the gear ring 13, transmitting the motor's rotational power to the sampling drill 1, driving it to rotate at high speed relative to the positioning disk 4.

[0032] Gear ring 13: It is fixedly sleeved on the outer surface of the sampling drill 1 and located inside the transmission groove 14. It meshes with the gear 12 to form a transmission pair, converting the rotational motion of the gear 12 into the rotation of the sampling drill 1, thereby realizing power transmission.

[0033] Transmission groove 14: It is opened inside the positioning plate 4 to provide meshing space for gear 12 and gear ring 13, while sealing the transmission structure to prevent external impurities from entering and ensuring transmission stability.

[0034] Feed trough 15: It is opened inside the sampling drill 1, runs through the drill axial direction, and provides an installation channel for the spiral guide blade 16, so that the mineral sample generated by drilling is transported upward along the trough to the external collection container under the action of rotation.

[0035] Spiral guide blade 16: Fixedly connected inside the feeding trough 15, it adopts a spiral blade structure. As the sampling drill 1 rotates, it generates axial thrust, continuously transporting the mineral sample from the bottom of the drill bit to the top outlet, realizing continuous sampling without stopping.

[0036] Through hole 17: It is opened at the top of the arc plate 5 and slides with the slide rod 3 to provide vertical sliding guide for the splash-proof positioning cylinder 2, ensuring that the splash-proof structure adapts to the drilling depth, while limiting the sliding direction to prevent deviation.

[0037] Example 1: like Figure 1-6 As shown, when sampling hard rock formations such as granite and limestone, the sampling drill 1 is aligned with the sampling point. The positioning plate 4 is pressed down by the handle 8, so that the positioning groove 10 at the bottom of the splash-proof positioning cylinder 2 is embedded into the surface of the rock formation. The initial fixation is achieved by the meshing of the groove with the rock. The drive motor 9 is started, and the gear 12 drives the gear ring 13 to rotate. The sampling drill 1 breaks the rock formation through the drilling teeth 11. At this time, the splash-proof positioning cylinder 2 forms an annular barrier because the sliding rod 3 is slidably connected to the through hole 17 of the arc plate 5, which prevents the broken rock fragments from splashing in all directions. The limiting ring 6 restricts the sliding rod 3 from sliding down too much.

[0038] Example 2: When sampling the flat and hardened structure, a splash-proof positioning cylinder 2 with a flat and anti-slip bottom is used. The material is high-hardness wear-resistant rubber with a Shore hardness of 85±5.

[0039] During sampling, the positioning disc 4 is pressed onto the concrete surface by the handle 8. The planar anti-slip structure fits tightly against the concrete surface. The planar design increases the contact area with the concrete by 20% compared to the original tooth groove structure, forming a closed annular splash barrier to prevent sharp debris generated by the drilling teeth 11 from breaking the concrete and splashing in all directions.

[0040] Furthermore, when using the device, the operator holds the handle 8 and aligns the device with the surface of the ore layer. The positioning groove 10 at the bottom of the splash-proof positioning cylinder 2 is embedded into the fixing device on the surface of the ore layer, while providing stable support for the splash-proof structure.

[0041] Start the drive motor 9, and its output end drives the gear 12 to rotate in the transmission groove 14. The gear 12 meshes with the toothed ring 13 fixed to the sampling drill 1, driving the sampling drill 1 to rotate at high speed relative to the positioning disk 4. The drilling teeth 11 rotate with the sampling drill 1 and cut into the ore layer to drill and sample.

[0042] The splash-proof positioning cylinder 2 is slidably sleeved on the outside of the sampling drill bit 1. Its top is slidably connected to the through hole 17 of the arc plate 5 through the slide rod 3, ensuring that the splash-proof positioning cylinder 2 can slide freely with the drilling depth. The limiting ring 6 restricts the sliding range of the slide rod 3 to prevent the splash-proof positioning cylinder 2 from falling off. During the drilling process, the slag is blocked by the splash-proof positioning cylinder 2 to avoid splashing onto the operators or the surrounding environment.

[0043] The sampling drill bit 1 has a feeding trough 15 inside, with a fixed spiral guide blade 16 inside. When rotating, the spiral guide blade 16 transports the mineral sample generated during drilling from the bottom of the drill bit to the top, and finally discharges it to the outside of the sampling drill bit 1 through the feeding trough 15, thus achieving continuous sampling. The protective cover 7 prevents dust or slag from splashing onto the operator.

[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
