Technical Field
[0001] The utility model relates to the technical field of rock crushing tests, and specifically relates to a mine geological rock sampling and crushing test device. Background Technique
[0002] A mine geological rock sampling and crushing test device is a device specifically designed to test the performance of rock samples during the crushing process. Such a device usually includes one or more crushers that can apply a strong force to crush the rock samples and simulate the actual conditions in mine exploitation or crushing operations. The crusher places the rock samples into the device and crushes them into smaller particles through mechanical action. The test device may also be equipped with a screening system to classify the crushed rock particles by size for convenient subsequent analysis. In addition, the device may have data recording and monitoring functions to accurately measure parameters such as crushing force and particle size distribution, so as to evaluate the physical properties and crushing characteristics of the rock. These data are of great significance for designing effective mine exploitation plans and evaluating the quality of ore;
[0003] After retrieval, the Chinese patent with the publication number CN211026523U discloses an ore sample crushing device for geological and mineral exploration. It is recorded in this patent that the ore sample enters the coarse crushing chamber through the feeding bin. Through the rotation of the crushing rollers, the ore sample is initially crushed in the coarse crushing chamber and enters the fine crushing chamber through the feeding channel; when the driving motor is turned on, the upper crushing rod and the lower crushing rod rotate, and the ore sample is further crushed in the fine crushing chamber. After crushing, it falls into the rolling chamber; the crushed particles fall along the screw rod cover, and the sliding rod drives the grinding wheel to make a reciprocating motion along with the forward and reverse rotation of the screw rod and drives the grinding wheel to rotate, so as to roll the particles after fine crushing into fine particles; the rotation of the lower crushing rod drives the spring to rotate, and the ball fixed at the lower end of the spring periodically knocks on the screw rod cover to shake off the ore particles remaining on the screw rod cover; after rolling is completed, the discharge plate is pulled out through the handle, so that the ore particles fall into the aggregate box. After collection is completed, the aggregate box is pulled out and the aggregate box is pushed to the testing room for sampling and testing.
[0004] In this solution, after the rock is crushed, it is directly sent to the testing room for testing. During the crushing process, since some rock particles are not thoroughly crushed during the crushing of the rock and are larger than other rock particles, and this device requires manual screening for re-crushing, which increases the labor intensity. At the same time, rock particles of different sizes will affect the experimental data during testing, resulting in different experimental data. To solve this technical problem, the utility model proposes a mine geological rock sampling and crushing test device. Content of the Utility Model

[0014] (III) Beneficial Effects
[0015] The utility model provides a mine geological rock sampling and crushing test device, which has the following beneficial effects:
[0016] (1) The crushed rocks fall on the sieve mesh. The driving of the motor makes the rotating shaft rotate, thus driving the cam to rotate. The rotation of the cam drives the baffle to move back and forth, and then drives the slider to slide in the chute. The movement of the slider makes the sieve mesh move back and forth in the conveying box. The movement of the sieve mesh combined with the vibration frequency of the spring improves the efficiency of the screening process. The vibration of the sieve mesh helps to screen out smaller rock particles, which flow out through the feeding hopper. When the electric push rod 1 starts, it pushes the pushing plate forward. The pushing plate pushes the larger rocks off the sieve mesh through the limiting action of the positioning rod 1, making them fall on the conveyor belt. The conveyor belt then transports these larger rocks to the designated position. This system effectively solves the problems of screening and classification after rock crushing. Through precise screening and classification, the working efficiency and the accuracy of rock data are improved, enabling geological engineers to obtain detailed information about the properties of rocks.
[0017] (2) The motor drives the rotating shaft to rotate. This movement is transmitted to the rotating rod through the pulley and belt, and then drives the crushing roller to rotate. The crushing roller crushes the rock material through relative movement in the crushing box. The electric push rod 2 and the positioning rod 2 are used in cooperation to adjust the pre-crushing plate to the appropriate position when needed. The baffle helps to guide the material into the crushing area or remove larger material blocks. The whole system effectively solves the problems of rock crushing and pre-treatment, ensures the uniform crushing of the material, simplifies the operation process, and improves the crushing efficiency and the reliability of the equipment.

Specific implementation mode
[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.
[0025] Please refer to Figures 1-5 , the present invention provides a technical solution:
[0026] Embodiment 1: A sampling and crushing test device for mine geological rocks includes a conveying box 2. A motor 3 is fixedly connected to the top of the conveying box 2. The output end of the motor 3 is fixedly connected to a rotating shaft 4, and the other end of the rotating shaft 4 is fixedly connected to a cam 5. A screen 7 is arranged inside the conveying box 2. Sliders 8 are fixedly connected to both sides of the screen 7. Chutes 6 are opened on both sides of the conveying box 2, and the sliders 8 are slidably connected in the chutes 6. A baffle 9 is fixedly connected to the top of one slider 8, and at the same time, the cam 5 corresponds to the baffle 9. Three springs 10 are fixedly connected to one side wall of the screen 7, and the other ends of the springs 10 are fixedly connected to the inner wall of the conveying box 2. An electric push rod I 11 is fixedly connected to the outer side wall of the conveying box 2. The output end of the electric push rod I 11 is fixedly connected to a pushing plate 12, and the pushing plate 12 is slidably connected to the top of the screen 7. A conveyor belt 15 is arranged inside the conveying box 2. A feeding hopper 14 is fixedly connected to the bottom of the conveying box 2. A pair of positioning rods I 13 are fixedly connected to the outer side wall of the pushing plate 12, and the positioning rods I 13 penetrate through the conveying box 2 and extend to the outside of the conveying box 2.
[0027] The crushed rocks will fall on the sieve 7. At the same time, the operation of the motor 3 causes the cam 5 to start rotating, thereby pushing the baffle 9 to move back and forth. This movement makes the slider 8 slide back and forth in the chute 6, and then drives the sieve 7 to move back and forth inside the conveying box 2 to complete the screening of the rocks. During the movement of the sieve 7, it cooperates with the elastic vibration of the spring 10 to enhance the vibration frequency of the sieve, thereby improving the screening efficiency. Through the screening of the sieve, the smaller rock particles will fall and flow out along the discharge hopper 14, while the larger rocks need to be further processed. The electric push rod 11 will start and push the pushing plate 12 forward. The pushing plate 12, through the limiting action of the positioning rod 13, pushes the larger rocks off the sieve 7 and makes them fall onto the conveyor belt 15. The conveyor belt 15 will convey these larger rocks out. This system ensures the effective separation of rock particles through an accurate screening and classification process. By this method, geological engineers can collect important data on rock hardness, strength, and fragmentation characteristics, thereby improving the processing efficiency and data accuracy.
[0028] Embodiment 2: The difference between this embodiment and Embodiment 1 is that a crushing box 1 is provided at the top of the conveying box 2. Inside the crushing box 1, a pair of rotating rods 18 are rotatably connected. At the same time, belt pulleys 16 are fixedly connected to the outer walls of both the pair of rotating rods 18 and the outer wall of the rotating shaft 4. The three belt pulleys 16 are connected by a belt 17. Crushing rollers 19 are fixedly connected to the outer walls of both sides of the rotating rods 18, and the crushing rollers 19 are rotatably connected inside the crushing box 1. At the same time, an inclined plate 26 is fixedly connected inside the crushing box 1. A housing 20 is fixedly connected to the top of the crushing box 1. An electric push rod 22 is fixedly connected to the top of the housing 20. The output end of the electric push rod 22 is fixedly connected to a pre-crushing plate 24, and the pre-crushing plate 24 is slidably connected inside the housing 20. A pair of positioning rods 23 are fixedly connected to the top of the pre-crushing plate 24, and the positioning rods 23 penetrate through the housing 20 and extend to the outside of the housing 20. A switch door 25 is provided on one side of the housing 20. A sliding plate 21 is slidably connected to the bottom of the housing 20.
[0029] The operator opens the switch door 25, places the rock to be processed on the slide plate 21 inside the housing 20, and starts the second electric push rod 22. The function of this push rod is to push the pre-crushing plate 24 downward, and at the same time, accurately position the rock through the second positioning rod 23. During the downward movement of the pre-crushing plate 24, it will initially crush the rock and break it into smaller chunks. After the pre-crushing is completed, the operator pulls out the slide plate 21, causing the rock to fall from the slide plate into the crushing box 1, and then starts the motor 3 at the top of the conveying box 2. The motor 3 drives the pulley 16 to rotate by rotating the rotating shaft 4. The rotation of the pulley 16 transmits power through the belt 17 to drive the rotating rods 18 on both sides to rotate. The movement of the rotating rods 18 drives the crushing rollers 19 to rotate at high speed. The crushing rollers 19 further crush the rock during rotation until the rock is completely crushed into fine particles. The cooperation of this series of components ensures the effective pre-treatment and crushing of the rock. The design and coordinated cooperation of the overall system optimize the rock crushing process and improve the convenience and effect of processing.
[0030] Working principle: When the staff needs to conduct a rock crushing experiment, first open the switch door 25 and place the rock on the slide plate 21 inside the housing 20. Then start the second electric push rod 22. Under the action of the second electric push rod 22, it drives the pre-crushing plate 24 to move downward, and at the same time, cooperates with the second positioning rod 23 for positioning. The rock is pre-treated into small pieces through the pre-crushing plate 24. Then pull out the slide plate 21, and the rock falls into the crushing box 1. At this time, start the motor 3 at the top of the conveying box 2. Under the action of the motor 3, it drives the rotating shaft 4 and the pulley 16 to rotate. When the pulley 16 rotates, it drives the other two rotating rods 18 to rotate through the belt 17. When the rotating rods 18 rotate, they will drive the crushing rollers 19 to rotate. The rock is completely crushed through the crushing rollers 19. Through their cooperation, the effect of rock pre-treatment is achieved, avoiding the problem of inconvenient crushing of large rocks. The crushed rock falls on the screen 7. At the same time, the rotation of the motor 3 will drive the cam 5 to rotate, which will then push the baffle 9 to move back and forth. When the baffle 9 moves, it will drive the slider 8 to move in the chute 6. The movement of the slider 8 will drive the screen 7 to move back and forth in the conveying box 2, thereby screening the rock. When the screen 7 moves, it cooperates with the elasticity of the spring 10 to strengthen the vibration frequency of the screen 7 and improve the screening effect. Smaller rocks will fall through the screen 7 and be discharged along the feeding hopper 14. Larger rocks are pushed forward by starting the first electric push rod 11. Under the action of the first electric push rod 11, the pushing plate 12 is pushed forward. The pushing plate 12 is limited by the first positioning rod 13, so as to push the larger rocks off the screen 7 and fall on the conveyor belt 15 and be conveyed away through the conveyor belt 15. Through their cooperation, the crushed rock particles are separated and classified. Through these tests, geological engineers can obtain information about rock hardness, strength, fragmentation characteristics, etc., improving work efficiency.
