Description

Technical Field

[0001] This invention belongs to the field of mining geological exploration technology and relates to a mining geological rock crushing and sampling device. Background Technology

[0002] In the field of mining geological exploration, obtaining rock samples is fundamental to conducting mineral resource assessments and geological structure analyses, and mining geological rock crushing and sampling devices are key equipment for achieving this process. Currently, there are many types of mining geological rock crushing and sampling devices on the market, each with different uses to meet sampling needs in various scenarios. These are mainly divided into large sampling devices and handheld crushing devices. The operation of handheld crushing devices typically involves the operator holding the device to strike the target rock, breaking it up, and then collecting the crushed sample. However, these handheld crushing devices present certain safety hazards and operational inconveniences in practical applications.

[0003] A Chinese utility model patent with publication number CN220339683U discloses a mining geological rock crushing and sampling device, comprising a gripping cylinder. A circular block is disposed inside the top of the gripping cylinder. Two connecting strips are symmetrically fixed to the surface of the circular block, one end of each connecting strip being fixedly connected to the inner wall of the gripping cylinder. A screw is disposed inside the gripping cylinder. The top of the screw is rotatably connected to the bottom of the circular block via a bearing, and the bottom of the screw is rotatably connected to the bottom of the gripping cylinder via a bearing. A knob is fixed to the bottom of the screw. A sliding cylinder is threadedly connected to the surface of the screw and slidably connected inside the gripping cylinder. A hammer is disposed at the top of the sliding cylinder.

[0004] The existing technology has the following technical defects: However, while the aforementioned technical solution effectively addresses the issue of fixed-length sampling hammers being inconvenient to carry due to their overall length, it suffers from several drawbacks in practical use. These drawbacks can easily lead to rock fragmentation, which can cause injury to operators. Furthermore, the complex terrain (such as slopes and rock piles) makes efficient and complete collection of the crushed rock samples difficult. Additionally, the initially crushed rock blocks are often quite large, requiring further crushing. This second crushing process inevitably results in further fragmentation, making sample collection more time-consuming and labor-intensive. It also increases the risk of the target sample mixing with impurities in the surrounding environment, affecting sample purity and the accuracy of subsequent testing results. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: to address the issue mentioned in the background art that rock fragments are easily generated after hammering rocks, and the fragmented rock fragments can easily cause personal injury to operators. The rock blocks after initial crushing are usually large and often need to be crushed again. However, during the second crushing process, rock fragments will still be generated and scattered. This not only makes sample collection more time-consuming and labor-intensive, but also easily leads to the target sample mixing with other impurities in the surrounding environment. The present invention provides a rock crushing and sampling device for mining geology.

[0010] A pull rod is fixedly connected to the end face of the limiting plate. The pull rod passes through the tail of the mounting tube and is slidably connected thereto. A pull ring is fixedly connected to the end of the pull rod.

[0011] The internal hexagonal ring is equipped with a hexagonal wrench, and a rotating handle is fixedly connected to the hexagonal wrench.

[0012] The anti-splash assembly includes a collection shell fixedly connected to the head of the installation pipe. The collection shell is conical in shape. A retaining ring corresponding to the breaking cone is provided at the front of the collection shell. The collection shell has evenly distributed collection openings on its inner side. A storage shell is fixedly connected to the outer side of the collection shell. The storage shell is connected to the inside of the collection shell.

A horizontal tube is sleeved at the end of the crossbar. An inclined plate is fixedly connected between the horizontal tube and the rack. A reinforcing plate is fixedly connected between the horizontal tube and the inclined plate.

[0019] Example 1 like Figures 1-6As shown, the mining geological rock crushing and sampling device of the present invention includes an installation pipe 1, an installation plate 2 slidably connected to the inner side of the installation pipe 1, a crushing cone 3 provided on the end face of the installation plate 2, a screw hole 4 opened on the crushing cone 3, a screw rod 5 threadedly connected to the screw hole 4, the other end of the screw rod 5 being fixedly connected to the installation plate 2, an anti-splashing component adapted to the crushing cone 3 provided on the installation pipe 1, a pop-out component adapted to the installation plate 2 provided inside the installation pipe 1, a locking mechanism adapted to the pop-out component provided inside the pop-out component, and a fixed connection to the outer side of the installation pipe 1. The grip 35; the anti-rock splash assembly is used to prevent rock splashing and collect rock particles, and the anti-rock splash assembly also includes a crushing mechanism; the ejection assembly includes a fixing plate 7 fixed inside the mounting tube 1, a crushing spring 6 fixedly connected between the fixing plate 7 and the mounting plate 2, a rack 8 fixedly connected to the top of the mounting plate 2, the rack 8 passing through the tail end face of the mounting tube 1 and slidably connected to the mounting tube 1, and symmetrical movable openings 20 on the outer side of the mounting tube 1, with movable blocks 21 slidably connected to the mounting plate 2 in each of the two movable openings 20. The ejector assembly further includes a drive shaft 10 rotatably connected within the mounting tube 1 and extending through both sides thereof. A gear 9, meshing with a rack 8, is fixedly connected to the drive shaft 10. Hexagonal rings 12 are fixedly connected to both ends of the drive shaft 10. The locking mechanism includes symmetrically opened limiting openings 13 at the tail of the mounting tube 1. A limiting plate 14 is slidably connected within the limiting openings 13. A limiting spring 18 is fixedly connected between the limiting plate 14 and the tail of the mounting tube 1. A pawl 15 is fixedly connected to the limiting plate 14. The hexagonal rings 12... A ratchet 11 is fixedly connected to the mounting tube 1, which engages with the pawl 15. A protective shell 19 corresponding to the limiting opening 13, ratchet 11, and pawl 15 is fixedly connected to the outside of the mounting tube 1. An internal hexagonal ring 12 passes through the protective shell 19 and is rotatably connected to it. A pull rod 16 is fixedly connected to the end face of the limiting plate 14. The pull rod 16 passes through the tail of the mounting tube 1 and is slidably connected to it. A pull ring 17 is fixedly connected to the end of the pull rod 16. A hexagonal wrench 42 is provided inside the internal hexagonal ring 12. A rotating handle 43 is fixedly connected to the hexagonal wrench 42.

[0020] First, insert the hex wrench 42 into the inside of the internal hex ring 12. Then, rotate the handle 43 to rotate the hex wrench 42 and the internal hex ring 12 clockwise. Simultaneously, the internal hex ring 12 drives the ratchet 11 and gear 9 to rotate clockwise. When the ratchet 11 rotates clockwise, it will repeatedly push the pawl 15 away from the ratchet 11 to compress the limit spring 18. When the gear 9 rotates clockwise, it will drive the rack 8 to move towards the pull ring 17. Simultaneously, the rack 8 will pull the mounting plate 2, screw 5, and crushing cone 3 towards the pull ring 17 to compress the crushing spring 6, which will concentrate the force. When the mounting plate 2 moves to the limit position towards the pull ring 17, you can stop rotating the handle 43. Simultaneously, the rebound force of the limit spring 18 will push the limit plate 14 and the pawl 15 to slide towards the gear 9, so that the pawl 15 holds the ratchet 11 and fixes the position of the crushing cone 3.

[0021] Example 2 like Figures 1 to 8 As shown, the anti-splashing assembly of the present invention includes a collection shell 22 fixedly connected to the head of the mounting pipe 1. The collection shell 22 is conical in shape. A retaining ring 24 corresponding to the breaking cone 3 is provided at the front of the collection shell 22. The collection shell 22 has evenly distributed collection openings 23 on its inner side. A storage shell 25 is fixedly connected to the outer side of the collection shell 22. The storage shell 25 is connected to the inside of the collection shell 22. A sealing cap 26 is fitted on the end face of the storage shell 25.

[0022] During operation, the handle 35 is held to contact and press the retaining ring 24 against the rock, so that the retaining ring 24 completely covers the area to be broken. Next, the limit plate 14 is pulled away from the gear 9 by the pull ring 17 and the pull rod 16 until the pawl 15 disengages from the ratchet 11. At this time, the elastic force of the breaking spring 6 is released instantly, pushing the mounting plate 2, screw 5 and breaking cone 3 out of the outside of the mounting tube 1, so that the breaking cone 3 can hammer the rock. When the rock is hammered, it will splatter. These rocks will be blocked by the collection shell 22 and enter the inner cavity of the collection shell 22 through the collection opening 23. Finally, they will slide down into the storage shell 25 on the lower side by gravity. This not only prevents rock particles from splattering, but also collects them, effectively avoiding the problem of rock particles scattering on the ground and being inconvenient to pick up.

[0023] Example 3 like Figures 1-9 As shown, the crushing mechanism of the present invention includes a pressure plate 27 disposed inside the storage shell 25. A crossbar 28 penetrating the storage shell 25 is fixedly connected to the end face of the pressure plate 27. A fixing ring 30 is fixedly connected to the crossbar 28. A return spring 29 is sleeved on the crossbar 28 between the fixing ring 30 and the storage shell 25. The two ends of the return spring 29 are fixedly connected to the storage shell 25 and the fixing ring 30, respectively. The crushing mechanism also includes a positioning post 31 fixedly connected to the mounting pipe 1. The positioning post 31 is provided with a positioning hole 36 adapted to the crossbar 28. The top of the positioning post 31 is open. A first threaded hole 37 is provided, and a first bolt 38 is threadedly connected to the first threaded hole 37. The first bolt 38 contacts the crossbar 28. A horizontal tube 32 is sleeved at the end of the crossbar 28. An inclined plate 33 is fixedly connected between the horizontal tube 32 and the rack 8. A reinforcing plate 34 is fixedly connected between the horizontal tube 32 and the inclined plate 33. A baffle 39 is provided on the outside of the storage shell 25, penetrating the storage shell 25 and slidably connected thereto. The baffle 39 is L-shaped and inclined. A second threaded hole 40 is provided at the top of the baffle 39, and a second bolt 41 is threadedly connected to the second threaded hole 40.

[0024] During operation, first loosen the second bolt 41 and pull the baffle 39 to its limit position, but avoid detaching the baffle 39 from the storage shell 25. Next, pull the crushing cone 3 towards the pull ring 17 to its limit position using the above operation, and use the pawl 15 to hold the ratchet 11 so that the gear 9 will not rotate. Then loosen the first bolt 38. At this time, the return spring 29 pushes the fixing ring 30 and the pressure plate 27 to slide towards the horizontal tube 32 to their limit position. Next, rotate the entire mounting tube 1 and the collection shell 22 to rotate the storage shell 25 containing the rock particles to the top. At this time, the rock particles will fall into the inside of the collection shell 22. Slightly shake the mounting tube 1 and the mounting plate 2 to make all the rock particles enter the storage shell below. Inside shell 25, the rock particles are in contact with pressure plate 27. Next, by pulling ring 17 as described above, the pawl 15 is disengaged from ratchet 11. At this time, mounting plate 2 and crushing cone 3 will pop out again. When mounting plate 2 pops out, it will also drive rack 8 and inclined plate 33 to slide quickly towards collection shell 22. Simultaneously, inclined plate 33 pushes horizontal tube 32 to slide towards collection shell 22. When horizontal tube 32 slides to the designated position, the inner wall of horizontal tube 32 will push horizontal bar 28 and pressure plate 27 to move towards collection shell 22, compressing return spring 29. In this way, pressure plate 27 can quickly press the rock particles, thereby achieving the purpose of crushing the rock again. If multiple crushing of the rock is required, the above operation can be repeated multiple times.

[0025] Working process or working principle: In use, first insert the hex wrench 42 into the inside of the internal hex ring 12. Then, rotate the handle 43 to rotate the hex wrench 42 and the internal hex ring 12 clockwise. Simultaneously, the internal hex ring 12 drives the ratchet 11 and gear 9 to rotate clockwise. When the ratchet 11 rotates clockwise, it repeatedly pushes the pawl 15 away from the ratchet 11, compressing the limit spring 18. When the gear 9 rotates clockwise, it drives the rack 8 to move towards the pull ring 17. Simultaneously, the rack 8 pulls the mounting plate 2, screw 5, and crushing cone 3 towards the pull ring 17, compressing the crushing spring 6 and concentrating the force. When the mounting plate 2 moves to the limit position towards the pull ring 17, you can stop rotating the handle 43. Simultaneously, the rebound force of the limit spring 18 pushes the limit plate 14 and pawl 15 towards the gear 9. The pawl 15 is moved so that it grips the ratchet 11 and fixes the position of the crushing cone 3. Next, the handle 35 is held so that the retaining ring 24 contacts the rock and is pressed down so that the retaining ring 24 completely covers the area to be crushed. Then, the limiting plate 14 is pulled away from the gear 9 by the pull ring 17 and the pull rod 16 until the pawl 15 disengages from the ratchet 11. At this time, the elastic force of the crushing spring 6 is released instantly, pushing the mounting plate 2, the screw 5 and the crushing cone 3 out of the mounting tube 1, so that the crushing cone 3 can hammer the rock. When the rock is hammered, it will shard the rock. These rocks will be blocked by the collection shell 22 and enter the inner cavity of the collection shell 22 through the collection opening 23. Finally, they will slide down into the storage shell 25 below by gravity. This not only prevents rock particles from falling into the storage shell 25, but also prevents the rock particles from falling into the storage shell 25 below. The fragmented rock particles can be collected, effectively preventing them from scattering on the ground and becoming difficult to pick up. When the rock particles in the storage shell 25 need to be crushed even smaller, first loosen the second bolt 41 and pull the baffle 39 to its limit position, but be careful not to let the baffle 39 detach from the storage shell 25. Next, pull the crushing cone 3 towards the pull ring 17 to its limit position using the above operation, and use the pawl 15 to hold the ratchet 11 so that the gear 9 will not rotate. Then loosen the first bolt 38. At this time, the return spring 29 pushes the fixing ring 30 and the pressure plate 27 to slide towards the horizontal tube 32 to their limit position. Next, rotate the entire mounting tube 1 and the collection shell 22 to rotate the storage shell 25 containing the rock particles from below to the top. Rock particles fall into the inside of the collection shell 22. Slight shaking of the mounting tube 1 and mounting plate 2 causes all the rock particles to enter the storage shell 25 below. At this point, the rock particles come into contact with the pressure plate 27. Next, by pulling the pull ring 17, the pawl 15 disengages from the ratchet 11. The mounting plate 2 and crushing cone 3 then pop out again. As the mounting plate 2 pops out, it also causes the rack 8 and inclined plate 33 to slide rapidly towards the collection shell 22. Simultaneously, the inclined plate 33 pushes the horizontal tube 32 towards the collection shell 22. When the horizontal tube 32 reaches the designated position, its inner wall pushes the horizontal bar 28 and pressure plate 27 towards the collection shell 22, compressing the return spring 29. This allows the pressure plate 27 to quickly press down on the rock particles.This achieves the purpose of further crushing the rock. If multiple crushing operations are required, the above operation can be repeated. After the rock particles are crushed, the sealing cover 26 can be opened to pour out the rock particles, or the sample can be stored through the storage shell 25. The crushing cone 3 can be replaced when needed. By rotating the crushing cone 3, the crushing cone 3 can be separated from the screw 5. Furthermore, the distance between the crushing cone 3 and the mounting tube 1 can be adjusted by rotating the crushing cone 3, thereby adjusting the impact depth of the crushing cone 3 on the rock to accommodate more different types of rocks.

[0026] The present invention covers the breakage point with a collection shell 22, preventing the broken rock from splashing outwards, and the fragments are collected inside the collection shell 22. This effectively solves the problem that splashed rock fragments can easily cause personal injury to operators. Furthermore, through the cooperation between the storage shell 25, rack 8, pressure plate 27, crossbar 28, horizontal tube 32, and inclined plate 33, when the rock needs to be broken again, the horizontal tube 32 can push the crossbar 28 and pressure plate 27 to break the rock again. This effectively solves the problem that after the rock fragments are scattered, the sample collection work is more time-consuming and laborious, and it is easy for the target sample to mix with other impurities in the surrounding environment.

[0027] The descriptions of the orientation and relative positional relationships of the structures in this invention, such as front, back, left, right, up, and down, do not constitute a limitation of this invention, but are merely for the convenience of description.
