[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-Figure 5 As shown, the utility model provides a rock sample crushing device for geological exploration, including a crushing box 1, the upper surface of the crushing box 1 is fixed and connected to a feed hopper 2, the inner wall of the crushing box 1 is rotatably connected to two crushing rollers 3, the outer wall of the crushing box 1 is fixedly connected to a motor 4, the output end of the motor 4 is fixedly connected to the crushing roller 3, the inner wall of the crushing box 1 is fixedly connected to a guide plate 5, the inner wall of the crushing box 1 is provided with a screening structure 6, and the inner wall of the crushing box 1 is provided with a buffer structure 7.

[0032] The specific configuration and function of the screening structure 6 and the buffer structure 7 will be described in detail below.

[0033] like Figure 3 and Figure 4 As shown, the screening structure 6 includes two rotating shafts 601, which are rotatably connected to the crushing box 1, and the arc surface of the rotating shaft 601 is fixedly connected to the screening plate 602, one end of the rotating shaft 601 is fixedly connected to the gear 603, the outer wall of the crushing box 1 is fixedly connected to the first electric push rod 604, the output end of the first electric push rod 604 is fixedly connected to the strip plate 605, the surface of the strip plate 605 is fixedly connected to the rack 606, the rack 606 is meshed with the gear 603, and the crushing box 1 is fixedly connected to the second electric push rod 607, the output end of the second electric push rod 607 is fixedly connected to the extrusion plate 608, the extrusion plate 608 is slidably connected to the crushing box 1, and the surface of the extrusion plate 608 is fixedly connected to a plurality of thorns 611, and the second electric push rod 607 is opened, and the extension of the output end of the second electric push rod 607 will drive the extrusion plate 608 to move along The crushing box 1 slides, and the sliding of the extrusion plate 608 will drive the spur 611 to move. When the spur 611 contacts the rock sample, the rock sample will be crushed, so that the rock sample is processed into a size that is convenient for the crushing roller 3 to crush. The outer wall of the crushing box 1 is fixedly connected with a fixed plate 609, and the fixed plate 609 is slidably connected to the strip plate 605. The fixed plate 609 has the function of limiting the sliding path of the strip plate 605. The surface of the fixed plate 609 is fixedly connected with a stopper 610, and the stopper 610 is slidably connected to the strip plate 605. When the strip plate 605 contacts the stopper 610, the stopper 610 will prevent the strip plate 605 from continuing to slide, thereby preventing the screening plate 602 from continuing to rotate, thereby ensuring that the two screening plates 602 can stably rotate to a horizontal state and contact each other, so as to facilitate the subsequent screening of the rock samples.

[0034] like Figure 5As shown, the buffer structure 7 includes a plurality of support rods 71, which are rotatably connected to the crushing box 1, and circular plates 73 are fixedly connected to both ends of the support rod 71. The arc surface of the support rod 71 is fixedly connected to a receiving plate 72. The arc surface of the support rod 71 is sleeved with two torsion springs 74, and the two ends of the torsion spring 74 are respectively fixedly connected to the crushing box 1 and the circular plate 73. A rubber pad 76 is fixedly connected to the surface of the receiving plate 72. The rubber pad 76 can buffer the rock sample and reduce the collision force between the rock sample and the receiving plate 72. A protective cover 75 is fixedly connected to the surface of the circular plate 73, and one end of the protective cover 75 is against the outer wall of the crushing box 1. The torsion spring 74 is located in the protective cover 75. By setting the protective cover 75, the torsion spring 74 can be shielded and protected.

[0035] The overall working principle is that when the rock sample is crushed during the geological survey, the rock sample is poured into the feed hopper 2, and the rock sample will slide downward and hit the rubber pad 76 on the surface of the receiving plate 72. The rubber pad 76 can cushion the rock sample and reduce the collision force between the rock sample and the receiving plate 72. The receiving plate 72 will rotate after being subjected to the force, and the rotation of the receiving plate 72 will drive the support rod 71 to rotate, and the rotation of the support rod 71 will drive the circular plate 73 to rotate. The rotation of the circular plate 73 will twist the torsion spring 74, and the torsion spring 74 will cushion the circular plate 73, thereby cushioning the receiving plate 72, and then delaying the falling speed of the rock sample, reducing The collision force between the low rock sample and the screening plate 602 is reduced. During this process, the protective cover 75 will follow the circular plate 73 to move along the surface of the crushing box 1. The friction between the protective cover 75 and the crushing box 1 can damp the torsion force of the torsion spring 74, thereby preventing the receiving plate 72 from reciprocating due to the torsion force of the torsion spring 74. At the same time, the protective cover 75 can also shield and protect the torsion spring 74. When the rock sample falls onto the surface of the screening plate 602, the screening plate 602 will screen the rock sample, and the larger rock sample will remain on the upper surface of the screening plate 602. Then, the second electric push rod 607 is turned on, and the output of the second electric push rod 607 is The extension of the output end will drive the extrusion plate 608 to slide along the crushing box 1, and the sliding of the extrusion plate 608 will drive the spur 611 to move. When the spur 611 contacts the rock sample, it will crush the rock sample, so that the rock sample is processed into a size that is convenient for the crushing roller 3 to crush. Then, the output end of the first electric push rod 604 is controlled to extend, and the strip plate 605 will slide downward along the surface of the fixed plate 609. The fixed plate 609 has the function of limiting the sliding path of the strip plate 605. The rack 606 slides with the strip plate 605 to drive the gear 603 to rotate. The rotation of the gear 603 will drive the rotating shaft 601 to rotate, and the rotating shaft 601 will drive the screening plate 60 2 slides downward and rests on the surface of the guide plate 5. At this time, the rock sample with the right size to be crushed will slide between the two crushing rollers 3. The output end of the motor 4 rotates to drive the crushing rollers 3 to crush the rock sample. Then, the output end of the first electric push rod 604 is controlled to shrink. At this time, the strip plate 605 slides upward and the screening plate 602 rotates upward. When the strip plate 605 contacts the stopper 610, the stopper 610 prevents the strip plate 605 from continuing to slide, thereby preventing the screening plate 602 from continuing to rotate, thereby ensuring that the two screening plates 602 can stably rotate to a horizontal state and contact each other, which is convenient for the subsequent screening of the rock samples.

[0036] 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.
