[0002] In the process of geological and mineral exploration, it is necessary to collect ore from the mining area for testing in order to determine the content of minerals in the ore. Before testing the ore, a crushing device is needed to crush the ore into the required size to avoid the ore being too large and affecting the testing.

[0003] The above-mentioned and prior art technologies have the following defects: after the ore is crushed, some larger particles are likely to exist in the ore sample.

[0029] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0031] like Figure 1-5 As shown, the utility model provides a sample crushing device for geological and mineral exploration, including a crushing box 1, the upper surface of the crushing box 1 is fixed and connected with a feed pipe 2, the inner wall of the crushing box 1 is slidably connected with a collecting box 3, the outer wall of the crushing box 1 is fixedly connected with a motor 4, the output end of the motor 4 is fixedly connected with a first gear 5, the inner wall of the crushing box 1 is rotatably connected with a first crushing roller 6, one end of the first crushing roller 6 is fixedly connected with a second gear 7, the first gear 5 is meshed with the second gear 7, the inner wall of the crushing box 1 is rotatably connected with a second crushing roller 10, one end of the second crushing roller 10 is fixedly connected with a third gear 11, the third gear 11 is meshed with the second gear 7, the inner wall of the crushing box 1 is fixedly connected with a material guide plate 12, the inner wall of the crushing box 1 is provided with a screening structure 8, and the surface of the crushing box 1 is provided with a material blocking structure 9.

[0032] The specific arrangement and function of the screening structure 8 and the material retaining structure 9 will be described in detail below.

[0033] like Figure 2 and Figure 3 As shown, the screening structure 8 includes a screen 81, which is fixedly connected to the crushing box 1, and the screen 81 is located below the first crushing roller 6 and the second crushing roller 10. Two telescopic plates 82 are fixedly connected to the bottom inner wall of the crushing box 1, and a blanking plate 83 is fixedly connected to the upper end of the telescopic plate 82. The blanking plate 83 is slidably connected to the screen 81. A rotating shaft 84 is rotatably connected in the crushing box 1, and the rotating shaft 84 is located below the blanking plate 83. A cam 86 is fixedly connected to the circular arc surface of the rotating shaft 84. A belt 85 is sleeved on the surface of the rotating shaft 84 and the third gear 11. When the third gear 11 rotates, the belt 85 drives the rotating shaft 84 to rotate. The rotation of shaft 84 will drive the cam 86 to rotate. During this process, the unloading plate 83 is first lifted up, and then the unloading plate 83 falls down quickly, so that the ore particles on the surface of the unloading plate 83 are shaken, and the sliding speed of the ore particles is accelerated. The arc surface of the rotating shaft 84 is fixedly connected with two rubber sleeves 87. When the unloading plate 83 slides downward, it will contact the rubber sleeves 87. The rubber sleeves 87 can reduce the collision force between the unloading plate 83 and the rotating shaft 84 to prevent the unloading plate 83 and the rotating shaft 84 from being damaged. The inner wall of the cam 86 is rotatably connected with two wheels 88, and the wheels 88 can reduce the friction between the cam 86 and the unloading plate 83.

[0034] like Figure 4 and Figure 5As shown, the material blocking structure 9 includes a baffle 91, which is slidably connected to the crushing box 1, a sliding frame 92 is fixedly connected to the surface of the baffle 91, a clamping plate 93 is fixedly connected to the upper surface of the crushing box 1, the clamping plate 93 is slidably connected to the sliding frame 92, and a screw rod 94 is rotatably connected to the surface of the sliding frame 92, and the arc surface of the screw rod 94 is threadedly connected to a limit plate 95, and the limit plate 95 is slidably connected to the clamping plate 93, one side of the clamping plate 93 is a serrated structure, and the serrated structure on the surface of the clamping plate 93 can increase the friction between the limit plate 95 and the clamping plate 93, and a scale groove 96 is opened on the surface of the baffle 91. During the adjustment process, the scale groove 96 can facilitate the experimenter to grasp the distance between the baffle 91 and the material guide plate 12.

[0035] The overall working principle is that when the ore sample needs to be crushed, the ore sample is poured into the feed pipe 2, and then the motor 4 is started. The rotation of the output end of the motor 4 will drive the first gear 5 to rotate, the first gear 5 will drive the second gear 7 to rotate, and the second gear 7 will drive the third gear 11 to rotate. At this time, the first crushing roller 6 and the second crushing roller 10 will rotate in opposite directions. When the ore sample slides between the first crushing roller 6 and the second crushing roller 10 along the surface of the guide plate 12, the first crushing roller 6 and the second crushing roller 10 will crush the ore sample, and the crushed ore particles will fall on the screen 81, and the screen 81 will screen the ore particles. At this time, the ore particles with qualified volume will fall into the collecting box 3, and the ore particles with larger volume will be along the screen. The surface of 81 slides onto the blanking plate 83. When the third gear 11 rotates, the belt 85 drives the rotating shaft 84 to rotate. The rotation of the rotating shaft 84 drives the cam 86 to rotate. During this process, the cam 86 cooperates with the rotating wheel 88 to lift the blanking plate 83 first, and then the rotating wheel 88 disengages from the blanking plate 83, and the blanking plate 83 falls rapidly, thereby shaking the ore particles on the surface of the blanking plate 83, accelerating the sliding speed of the ore particles, and preventing the ore particles from accumulating on the blanking plate 83. The rotating wheel 88 can reduce the friction between the cam 86 and the blanking plate 83. When the blanking plate 83 slides downward, it will contact the rubber sleeve 87. The rubber sleeve 87 can reduce the collision force between the blanking plate 83 and the rotating shaft 84, and prevent the blanking plate 83 and the rotating shaft 84 from being damaged.

[0036] When it is necessary to control the weight of the ore sample that slides between the first crushing roller 6 and the second crushing roller 10, the baffle 91 is slid along the crushing box 1. When the baffle 91 slides upward, the distance between the baffle 91 and the guide plate 12 becomes larger, and the weight of the ore sample becomes larger. When the baffle 91 slides downward, the distance between the baffle 91 and the guide plate 12 becomes smaller, and the weight of the ore sample becomes smaller. Therefore, the weight of the ore sample can be adjusted according to the crushing speed of the first crushing roller 6 and the second crushing roller 10 to avoid the ore sample being too heavy and accumulating on the first crushing roller 6 and the second crushing roller 10, affecting the first crushing roller 6 and the second crushing roller 10. The crushing roller 6 and the second crushing roller 10 can work normally, and it can also avoid that the crushing efficiency is reduced due to the small amount of ore samples. During the adjustment process, the scale groove 96 can facilitate the experimenter to grasp the distance between the baffle 91 and the guide plate 12. After the adjustment is completed, the screw rod 94 is rotated, and the screw rod 94 will drive the limit plate 95 to move with the help of the thread. When the limit plate 95 is against one side of the serrated structure of the splint 93, the limit plate 95 reaches the position of the limit screw rod 94, thereby limiting the position of the baffle 91. The serrated structure on the surface of the splint 93 can increase the friction between the limit plate 95 and the splint 93.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
