[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0014] Referring to Figures (1-3), a portable rock crushing device for geological survey includes a crushing barrel 1, a crushing chamber 12 is opened inside the crushing barrel 1, and a top cover 2 is installed at the top opening, the top cover 2 is penetrated by a slide rod 21 and is slidably connected to the slide rod 21, one end of the slide rod 21 is connected to a crushing block 22, and the other end is connected to a top block 23, the crushing block 22 is slidably set in the crushing barrel 1, a conical crushing cone 11 is provided at the bottom of the crushing barrel 1, a pair of mounting plates 4 are provided on the outside of the crushing barrel 1, and a handle 3 is installed between the two mounting plates 4.

[0015] The mounting plate 4 has mounting holes 41, and the handle 3 has openings 31 at the ends and in the middle. These holes 41 and 31 allow for the insertion of fixing bolts 5, which are threaded with fixing nuts 51. The top cover 2 is threadedly connected to the crushing drum 1. One end of the handle 3 is provided with a grip for a person to grasp.

[0016] When using the device, remove the fixing bolt 5, place the end of the handle 3 with the opening 31 between the mounting plates 4, then pass the fixing bolt 5 through the opening 31 and the mounting hole 41, screw on the fixing nut 51, fix the handle 3 to the mounting plate 4, use the crushing cone 11 to knock on the rock formation, knock off some rock blocks, put the rock blocks into the crushing chamber 12, and screw on the top cover 2 at the opening.
