Detailed Implementation

[0019] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 , Figure 2 , Figure 3 This utility model provides a technical solution: a mineral exploration sample crushing device, including a frame 1, a feed inlet 2, a crushing integrated device 3, a conveying device 4, a main drive device 5, a transmission device 6, and a reciprocating drive device 7. The feed inlet 2 is provided on the top surface of the frame 1, and the mineral exploration sample enters the device from the feed inlet 2.

[0021] The integrated crushing device 3 is disposed on the bottom surface of the feed inlet 2. The crusher housing 33 of the integrated crushing device 3 is detachably connected to the bottom surface of the feed inlet 2. Two crushing rollers 31 are rotatably connected inside the crusher housing 33 for crushing the sample. The integrated crushing device 3 also includes two sleeve rollers 32. The sleeve rollers 32 are rotatably connected inside the transmission device 6 and are sleeved on the end of the crushing roller 31 away from the reciprocating drive device 7. The sleeve rollers 32 are connected to the end of the crushing roller 31 away from the reciprocating drive device 7 by an elastic element, which can play a role in buffering and resetting.

[0022] The inner cavity sidewall of the sleeve roller 32 is provided with a positioning groove, and one end of the crushing roller 31 is provided with a positioning protrusion. The positioning protrusion of the crushing roller 31 is slidably connected to the positioning groove of the sleeve roller 32. This design is similar to a spline connection, so that the sleeve roller 32 and the crushing roller 31 rotate synchronously.

[0023] It should be noted that the crushing roller 31 is made of iron material.

[0024] The conveying device 4 is disposed on the bottom surface of the crushing integrated device 3. The conveying housing 41 of the conveying device 4 is connected to the bottom surface of the crushing integrated device 3. The auger 42 is rotatably connected inside the conveying housing 41. The bottom surface of the conveying housing 41 is provided with the discharge port 43. The crushed sample is conveyed to the discharge port 43 through the auger 42 and discharged.

[0025] The frame 1 is also equipped with the main drive device 5. The drive end of the main drive device 5 is connected to one end of the auger 42 of the conveying device 4, providing power for the rotation of the auger 42. The other end of the auger 42 of the conveying device 4 is connected to the sleeve roller 32 of the crushing integrated device 3 through the transmission device 6. The transmission housing 61 of the transmission device 6 is disposed on the side wall of the frame 1. The first pulley set 62 and the second pulley set 63 are both disposed in the transmission housing 61. One end of the first pulley set 62 is connected to the auger 42, and the other end of the first pulley set 62 is connected to one of the sleeve rollers 32. The two sleeve rollers 32 are connected through the second pulley set 63, so that the rotation of the auger 42 drives the sleeve roller 32 to rotate, thereby driving the crushing roller 31 to rotate.

[0026] The frame 1 is equipped with the reciprocating drive device 7. The drive end of the actuating roller motor 71 of the reciprocating drive device 7 is connected to the actuating roller 72. A plurality of actuating arc plates 721 and a plurality of magnets 722 are evenly arranged on the circumferential side wall of the actuating roller 72. A magnet 722 is arranged between two actuating arc plates 721. The actuating roller motor 71 drives the actuating roller 72 to rotate. The actuating arc plates 721 and the magnets 722 cooperate to make the crushing roller 31 reciprocate, thereby improving the crushing effect.

[0027] like Figure 1 As shown, the actuating roller 72 in Figure 1 The middle edge rotates counterclockwise, and the actuating arc plate 721 actuates the crushing roller 31 to move towards Figure 1 When the actuating arc plate 721 moves to the left, and the restoring force of the elastic element at the left end of the crushing roller 31 disengages from the right end of the crushing roller 31, the crushing roller 31 is pushed to the right by the restoring force of the elastic element at the left end of the crushing roller 31. At this time, combined with the attraction force of the magnet 722 on the crushing roller 31, the crushing roller 31 is further moved to the right, increasing the reciprocating movement distance of the crushing roller 31.

[0028] In this invention, the main drive device 5 includes a motor and a pulley transmission structure. The motor drive end is connected to one of the pulleys, and the other pulley is connected to the auger 42. The first pulley group 62 and the second pulley group 63 are also pulley transmission structures. The pulley transmission in this invention achieves power transmission through the friction between the driving pulley, the driven pulley, and the belt. Its core principle can be broken down into the following steps:

[0029] When the drive pulley rotates, its surface contacts the belt, generating static friction. This frictional force is in the opposite direction to the rotation of the drive pulley, creating a resistance torque, but simultaneously driving the belt to move synchronously with the drive pulley. For example, in a car engine, the crankshaft pulley acts as the drive pulley, driving the air conditioning compressor pulley to rotate through friction.

[0030] The belt moves under the drive of the driving pulley, and static friction is generated again when it comes into contact with the driven pulley. This frictional force is in the same direction as the rotation of the driven pulley, forming a torque that drives the driven pulley to rotate. By adjusting the diameter ratio of the driving and driven pulleys, the rotational speed can be precisely adjusted. For example, in textile machinery, combinations of pulleys with different diameters convert the high-speed rotation of the motor into the low-speed, high-torque output required for yarn production.

[0031] The belt exhibits two states during transmission:

[0032] Upper belt tension: When the frictional forces of the driving pulley and the driven pulley are in opposite directions, the upper belt is under tension and is in a taut state, ensuring the continuity of power transmission.

[0033] The lower belt is slack: At this time, the lower belt only serves a supporting function, reducing friction loss and improving transmission efficiency.

[0034] This design enables belt pulley drives to maintain stability during long-distance power transmission, such as in mining machinery and conveyors.

[0035] Belt drive systems can transmit power over long distances, such as several meters or even tens of meters, between two shafts. This characteristic makes them widely used in mining machinery, conveyors, and other applications requiring long-distance power distribution. For example, in open-pit coal mines, belt drive systems can transmit power from a crusher to a conveyor belt several kilometers away.

[0036] Belt drives consist of a driving pulley, a driven pulley, a belt, and a tensioning device. They are compact and easy to manufacture. Their material costs, such as cast iron and aluminum alloys, as well as processing costs, are lower than those of gear drives, making them suitable for large-scale industrial applications. In agricultural machinery, belt drives are the preferred power output solution for tractors due to their low cost and ease of maintenance.

[0037] When the load exceeds the rated power of the belt drive system, the belt will slip in the pulley grooves, preventing damage to the equipment due to overload. This characteristic is especially important in applications requiring frequent start-stop operations, such as packaging machinery and mixers. For example, in food packaging machines, belt drives prevent motor burnout caused by material jamming.

[0038] The elasticity of belts can absorb vibrations and shocks during transmission, reducing noise and improving transmission smoothness. In textile machinery, belt drives can reduce the risk of yarn breakage; in air conditioning compressors, their low-noise characteristics can enhance the user experience.

[0039] It should be noted that the two pulleys of the second pulley group 63 must be of the same specification to avoid interference and jamming caused by the different rotation speeds of the two rollers 32 driving the crushing roller 31.

[0040] Working principle:

[0041] Mineral exploration samples are fed into the feed inlet 2 and enter the crushing integrated device 3. The actuating roller motor 71 of the reciprocating drive device 7 drives the actuating roller 72 to rotate. The actuating arc plate 721 and the magnet 722 work together to make the crushing roller 31 reciprocate, crushing the sample and simultaneously shaking the material in the conveyor housing 41 to prevent blockage. At the same time, the main drive device 5 drives the auger 42 to rotate, and the auger 42 drives the crushing roller 31 to rotate through the transmission device 6. The crushed sample is conveyed by the auger 42 of the conveying device 4 and discharged from the discharge port 43, completing the entire crushing process.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.

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.
