The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0023] like Figure 1 As shown, the utility model provides a rock sample crushing device for geological exploration, including a box body 1, three hydraulic cylinders 2 are arranged on the bottom end of the box body 1, and the three hydraulic cylinders 2 are arranged around a collecting basin 9. A crushing table 3 is fixedly installed on the top of the output shaft of the hydraulic cylinder 2, and the crushing table 3 can be pushed up and down by the hydraulic cylinder 2. A crushing hole is opened at the center of the crushing table 3, and a plurality of first protrusions 4 are fixedly installed on the hole wall of the crushing hole. A mounting plate 5 is fixedly installed on the upper part of the box body 1, and a crushing motor 6 is fixedly installed on the mounting plate 5. A crushing roller 7 is fixedly installed at the end of the output shaft of the crushing motor 6, and the crushing roller 7 is located in the crushing hole. The crushing roller 7 and the crushing hole are both set to be larger at the top and smaller at the bottom, and the gap between the crushing roller 7 and the crushing hole is also set to be larger at the top and smaller at the bottom. The rock sample falls downward after being squeezed, and then continues to be squeezed for further crushing.

[0024] A feeding port is provided at the side end of the box body 1, and a feeding door 8 is abutted in the feeding port.

[0025] Rock samples can be added into the box 1 through the feeding door 8. The rock samples enter between the crushing roller 7 and the crushing hole, are rubbed and squeezed by the crushing roller 7, and are thus crushed. They then descend along between the crushing roller 7 and the crushing hole, and continue to be rubbed and squeezed by the crushing roller 7 until the rock sample powder is discharged from the bottom of the crushing hole and enters the collecting basin 9.

[0026] In this embodiment, the lower side end of the box body 1 is hinged with an outlet door, and a collecting basin 9 is arranged on the bottom end of the box body 1, and a filter screen is movably arranged in the collecting basin 9. After the rock sample powder enters the collecting basin 9, it is screened by the filter screen, and the qualified powder falls into the bottom end of the collecting basin 9, and the unqualified rock sample fragments remain on the filter screen.

[0027] In this embodiment, a plurality of second protrusions 10 are fixedly mounted on the side wall of the crushing roller 7 to enhance the crushing effect. The first protrusion 4 cooperates with the second protrusion 10 to achieve a better crushing effect.

[0028] In this embodiment, a heat sink 11 is provided on the top of the box body 1 to facilitate heat dissipation of the crushing motor 6. A handle is fixedly mounted on the heat sink 11 to facilitate carrying.

[0029] In this embodiment, a slide groove is provided at the outer end of the crushing table 3, and a slider is fixedly installed on the inner wall of the box body 1. The slider is slidably installed in the slide groove. The crushing table 3 is limited by the cooperation of the slider and the slide groove, which does not affect the up and down movement of the crushing table 3 and prevents the crushing table 3 from rotating.
