[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0058] In the embodiments of this invention, please refer to Figures 1 to 8 A sample crushing device for geological and mineral exploration, comprising a feed housing 2, and further comprising:

[0059] The top of the arc-shaped shell 1 is connected to the bottom of the feed shell 2 and communicates with its interior. The bottom of the arc-shaped shell 1 is provided with several sets of discharge holes.

[0060] The discharge housing 3 is located inside the arc-shaped housing 1 and rotates against its inner wall. The discharge housing 3 is arc-shaped and has several sets of discharge holes.

[0061] Motor 4 is connected to the arc-shaped housing 1;

[0062] The crushing mechanism 5 has one end connected to the feed housing 2 and the other end connected to the output end of the motor 4, and is used to perform initial crushing of the sample.

[0063] Crushing mechanism 2 6 has one end connected to the discharge shell 3 and the other end connected to the output end of the motor 4, and is used to perform secondary crushing of the sample;

[0064] The pressing mechanism 7 is used to shield and press the sample. The pressing mechanism 7 includes: a triangular pressing plate 71, located inside the feeding shell 2, and the triangular pressing plate 71 is located on top of the crushing mechanism 5; a pressure drop and recovery assembly 72, one end of which is connected to the crushing mechanism 6 and the other end of which is connected to the arc shell 1, for driving the triangular pressing plate 71 to move longitudinally; and a pressure buffer assembly 73, one end of which is connected to the triangular pressing plate 71 and the other end of which is connected to the pressure drop and recovery assembly 72, for buffering the pressure.

[0065] The collection mechanism 8 is connected to the bottom of the arc-shaped housing 1 and is used to collect samples that fall from the discharge hole 1.

[0066] In this embodiment, the top of the feed housing 2 is a slanted structure, and the inner diameter of the feed housing 2 gradually decreases from top to bottom, forming a frustum shape that is larger at the top and smaller at the bottom.

[0067] As one embodiment of the present invention, please refer to Figure 1 , Figures 3 to 5 The crushing mechanism 5 includes:

[0068] The crushing roller 51 is located inside the feed housing 2 and is rotatably connected to it. The crushing roller 51 is provided in several groups.

[0069] Gear 52 is connected to crushing roller 51, and two adjacent sets of gears 52 are in a meshing state.

[0070] One end of the transmission belt 53 is connected to the output end of the motor 4, and the other end is connected to a set of crushing rollers 51.

[0071] When it is necessary to crush geological and mineral samples, the sample is first poured into the feed port at the top of the feed housing 2. After the sample enters the feed housing 2, the crushing roller 51 in the crushing mechanism 5 starts to rotate under the drive of the motor 4 and the drive belt 53. The adjacent crushing rollers 51 rotate in coordination through the meshing of gear 52 to crush the sample for the first time.

[0072] As one embodiment of the present invention, please refer to Figure 1 , Figures 3 to 8 The crushing mechanism 26 includes:

[0073] The crushing roller 61 is located inside and connected to the discharge housing 3, and the crushing roller 61 is connected to the output end of the motor 4;

[0074] The rotating component 62 is connected at one end to the output end of the motor 4 and at the other end to the discharge housing 3, and is used to drive the discharge housing 3 to rotate.

[0075] The material throwing component 63 is connected at one end to the arc-shaped shell 1 and at the other end to the discharge shell 3, and is used to throw the sample.

[0076] After the initial crushing, the sample falls into the discharge housing 3. Driven by the motor 4, the crushing roller 61 rotates at high speed, striking and impacting the sample entering the discharge housing 3 for secondary crushing. The motor 4 drives the rotating component 62 to rotate, which in turn drives the discharge housing 3 to rotate in the opposite direction to the crushing roller 61. The discharge housing 3 drives the throwing component 63 to move, which throws the sample up, making the sample evenly dispersed in the discharge housing 3, avoiding sample accumulation, and ensuring that the sample falls from the discharge hole. At the same time, the throwing component 63 throws the sample up, causing the crushing roller 61 to strike, impact, and crush the sample.

[0077] As one embodiment of the present invention, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 6 The rotating assembly 62 includes:

[0078] Gear 2, 621, is connected to the output terminal of motor 4;

[0079] Gear 3, 622, meshes with gear 2, 621;

[0080] Rotate the lever 623, one end of which is rotatably connected to gear 622, and the other end is connected to the arc-shaped housing 1;

[0081] Gear ring 624 meshes with gear three 622;

[0082] The fixed bending rod 625 is connected at one end to the toothed ring 624 and at the other end to the discharge housing 3.

[0083] Motor 4 drives gear 2 621 to rotate, gear 2 621 drives gear 3 622 to rotate, gear 3 622 drives gear ring 624 to rotate, gear ring 624 drives fixed bending rod 625 to rotate, fixed bending rod 625 drives discharge shell 3 to rotate, and the direction of rotation of discharge shell 3 is opposite to the direction of rotation of crushing roller 61. The rotation of discharge shell 3 causes the sample to continuously tumble and move inside discharge shell 3, making full contact with crushing roller 61, thereby improving the effect and uniformity of secondary crushing.

[0084] As one embodiment of the present invention, please refer to Figures 3 to 5 , Figure 7 and Figure 8 The throwing assembly 63 includes:

[0085] A fixing rod 631 is connected to the arc-shaped housing 1. The fixing rod 631 is provided in several groups and is arranged in a circumferential manner with equal spacing.

[0086] The rotating rod 632 is connected to the discharge housing 3. The rotating rod 632 is provided in several groups and is arranged in a circumferential manner with equal spacing.

[0087] The throwing plate 633 is rotatably connected to the rotating rod 632 in the middle, and the throwing plate 633 is in the shape of a folded plate.

[0088] The spiral spring 634 is connected at one end to the rotating rod 632 and at the other end to the throwing plate 633.

[0089] The discharge housing 3 drives the rotating rod 632 to revolve around the central axis of the discharge housing 3. The rotating rod 632 drives the throwing plate 633 to rotate synchronously. The throwing plate 633 scoops up the sample. When the throwing plate 633 rotates to contact and impact the fixed rod 631, it causes the throwing plate 633 to flip around the rotating rod 632 and scatter the sample. The spiral spring 634 ensures that the throwing plate 633 can return to its original position.

[0090] As one embodiment of the present invention, please refer to Figures 1 to 6 The voltage drop recovery component 72 includes:

[0091] The inclined block 721 abuts against the fixed folding rod 625 located at the bottom, and the inclined block 721 has inclined sides on both sides;

[0092] Connecting frame plate 722 is connected to inclined block 721;

[0093] The telescopic rod 723 is connected to the connecting frame plate 722 at its bottom end and to the arc-shaped shell 1 at its top end;

[0094] Elastic element 724 is connected to the connecting frame plate 722 at its bottom end and to the arc-shaped shell 1 at its top end;

[0095] The fixed abutment ring 725 is connected to the pressure buffer assembly 73.

[0096] During the revolution of the fixed bending rod 625, different fixed bending rods 625 intermittently abut against the inclined block 721. With the cooperation of the elastic element 724, the inclined block 721 continuously moves up and down in a straight line. The inclined block 721 drives the triangular pressure plate 71 to reciprocate longitudinally through the pressure buffer assembly 73. During the downward movement of the triangular pressure plate 71, it presses the sample entering the feed housing 2, ensuring that the crushing roller 51 crushes the sample, while preventing the sample from bouncing upward during the initial crushing process. During the upward movement of the triangular pressure plate 71, it pushes the sample inside the feed housing 2 upward, preventing the sample from getting stuck inside the feed housing 2. The elastic element 724 can be a spring, sheet metal, etc.

[0097] In this embodiment, the upward elastic force provided by the elastic element 724 is greater than the weight of the sample, ensuring that the triangular pressure plate 71 can rebound upward under the pressure of the sample.

[0098] As one embodiment of the present invention, please refer to Figures 1 to 6 The pressure buffer assembly 73 includes:

[0099] The bottom end of the folding tube 731 is connected to the connecting frame plate 722;

[0100] The sliding folding rod 732 is slidably connected to the folding cylinder 731, and its top end is connected to the triangular pressure plate 71. The sliding folding rod 732 is connected to the fixed abutment ring 725.

[0101] The elastic element 733 is connected at its bottom end to the folding cylinder 731 and at its top end to the bottom end of the sliding folding rod 732.

[0102] During the pressing process of the triangular pressure plate 71, the elastic element 733 acts as a buffer, making the pressing process more stable and avoiding excessive compression damage to the sample. At the same time, it can automatically adjust the pressing force according to the hardness of the sample and the feed rate to ensure the stability of the crushing effect. The elastic element 733 can be a spring, sheet metal, etc.

[0103] As one embodiment of the present invention, please refer to Figures 1 to 4 The collection mechanism 8 includes:

[0104] The limiting folding plate 81 is connected to the bottom of the arc shell 1 and is symmetrically located on both sides of the discharge hole 1;

[0105] Positioning block 83 is connected to one side of limiting folding plate 81;

[0106] The collection frame 82 is slidably engaged with the limiting folding plate 81, and its rear side abuts against the positioning block 83. The collection frame 82 is located at the bottom of the discharge hole.

[0107] The collection frame 82 is inserted into the limiting folding plate 81, and the positioning block 83 positions the collection frame 82, which facilitates the installation and disassembly of the collection frame 82, and also facilitates the collection, transfer and subsequent processing of the fragmented sample.

[0108] The working principle of this invention is as follows: When it is necessary to crush geological mineral samples, the sample is first poured into the feed port at the top of the feed housing 2. After the sample enters the feed housing 2, under the drive of the motor 4 and the drive of the transmission belt 53, the crushing roller 51 in the crushing mechanism 5 starts to rotate. The adjacent crushing rollers 51 achieve mutual rotation through the meshing of gear 52 to perform the initial crushing of the sample.

[0109] The crushed sample falls downwards into the discharge housing 3. Driven by the motor 4, the crushing roller 61 rotates at high speed, striking and impacting the sample entering the discharge housing 3 for secondary crushing. Simultaneously, the motor 4 drives gear two 621 to rotate, which in turn drives gear three 622, which in turn drives gear ring 624. Gear ring 624 then drives fixed bending rod 625 to rotate, which in turn drives the discharge housing 3 to rotate in the opposite direction to the crushing roller 61. The rotation causes the sample to continuously tumble and move within the discharge housing 3. The discharge housing 3 drives the rotating rod 632 to revolve around the central axis of the discharge housing 3. The rotating rod 632 drives the throwing plate 633 to rotate synchronously. The throwing plate 633 scoops up the sample. When the throwing plate 633 rotates to contact and impact the fixed rod 631, it causes the throwing plate 633 to tumble around the rotating rod 632, scattering the sample and ensuring full contact with the crushing roller 61, thereby improving the effect and uniformity of secondary crushing. The crushed sample falls from the discharge hole 1 into the collection frame 82 for collection.

[0110] The discharge shell 3 rotates continuously, causing the sample after the initial crushing to fall intermittently into the discharge shell 3, thus avoiding excessive sample from affecting the crushing effect;

[0111] During the revolution of the fixed bending rod 625, different fixed bending rods 625 intermittently abut against the inclined block 721. With the cooperation of the elastic element 724, the inclined block 721 continuously moves up and down in a straight line. The inclined block 721 drives the triangular pressure plate 71 to move longitudinally and reciprocally through the pressure buffer assembly 73. During the downward movement of the triangular pressure plate 71, it presses the sample entering the feed housing 2 to ensure that the crushing roller 51 crushes the sample and prevents the sample from bouncing upward during the initial crushing process. The elastic element 733 plays a buffering role, making the pressing process more stable and avoiding excessive compression damage to the sample. At the same time, it can automatically adjust the pressing force according to the hardness of the sample and the feed amount to ensure the stability of the crushing effect. During the upward movement of the triangular pressure plate 71, the triangular pressure plate 71 pushes the sample inside the feed housing 2 upward to prevent the sample from being blocked inside the feed housing 2.

[0112] As the triangular pressure plate 71 moves downward, the distance between the triangular pressure plate 71 and the two sides of the feed housing 2 gradually decreases. As the triangular pressure plate 71 moves upward, the distance between the triangular pressure plate 71 and the two sides of the feed housing 2 gradually increases, ensuring that the crushing roller 51 crushes the sample multiple times in small quantities.

[0113] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0114] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
