The two ends of the connecting block 201 are provided with rotating slots that are adapted to the U-shaped frame 101. One end of each of the two U-shaped frames 101 is rotatably connected to the inside of the rotating slot. The inner side wall of the mounting slot is movably connected to a limiting plate 202. A spring 203 is connected between one side of the limiting plate 202 and the inner side wall of the mounting slot to provide a reset force so that the limiting plate 202 remains in a locked state when there is no external force. Multiple locking blocks 204 are fixedly connected to the other side of the limiting plate 202. The two work together to realize the rotation positioning of the U-shaped frame and fix the unfolded or folded state of the filter 1. Multiple locking slots adapted to the locking blocks 204 are provided on the inner side wall of the rotating slot. A button 205, an operation interface, is fixedly connected to the other side of the limiting plate 202 for the user to control the triggering of the folding function. The mixing assembly 3 includes a first mixing rod 301, a second mixing rod 302, and a third mixing rod 303 arranged sequentially from bottom to top. The bottom of the first mixing rod 301 is provided with a cross-shaped mixing head 305, which is a component that directly contacts the rock sample and breaks up the lumpy rock sample by rotation. The bottom of the first mixing rod 301, the second mixing rod 302, and the third mixing rod 303 are all equipped with threaded rods 304 to realize detachable connection between each mixing rod and with the cross-shaped mixing head 305. The top of the first mixing rod 301, the second mixing rod 302, and the cross-shaped mixing head 305 are all provided with threaded grooves that are adapted to the threaded rods 304. A collection box 4 is provided at the bottom of the filter screen 1. An anti-slip pad is fixedly connected to the bottom of the collection box 4. The collection box 4 at the bottom of the filter screen 1 can directly receive the rock sample particles after screening, avoid sample loss caused by rock sample spillage, and improve sample utilization. The top of the filter screen 1 is equipped with a protective plate 5, and two connecting brackets 6 are installed on the top of the protective plate 5. The protective plate 5 on the top of the filter screen 1 can prevent rock sample particles from splashing out due to stirring or vibration during the screening process, and at the same time prevent splashed particles from causing accidental injury to the operators. Two connecting frames 6 are mounted on opposite sides with a crossbar. A mounting sleeve 7 is mounted at the center of the crossbar. A limiting ring 8 is fitted on the surface of the second stirring rod 302. The mounting sleeve 7 is compatible with the limiting ring 8. The limiting ring 8 can limit and guide the rotation of the stirring rod, ensuring that the stirring rod rotates stably within a fixed trajectory, thereby improving the stirring and screening efficiency. The top of the third stirring rod 303 is equipped with a connecting rod 9 compatible with a handheld electric drill interface. The connecting rod 9 is hexagonal in shape. The connecting rod 9 allows the stirring assembly 3 to be operated manually or connected to a handheld electric drill for electric stirring, thereby improving the applicability and work efficiency of the equipment. Positioning blocks 10 are fixedly connected to the top of the collection box 4 and the bottom of the protective plate 5. Positioning slots that match the positioning blocks 10 are opened at the top and bottom of the U-shaped frame 101. The positioning blocks 10 can play a positioning role when installing the collection box 4 and the protective plate 5, ensuring that each component is quickly and accurately assembled into place, and improving the equipment assembly efficiency.

[0018] In this invention, the working steps of the device are as follows: First step: When it is necessary to fold the filter screen 1, press the button 205 on both sides of the U-shaped frame 101. The button 205 drives the limiting plate 202 to move into the mounting groove, compressing the spring 203. When the limiting plate 202 moves, the locking block 204 on its surface disengages from the locking groove on the inner side wall of the connecting block 201, releasing the rotation restriction on the U-shaped frame 101. At this time, the two U-shaped frames 101 can be rotated around the rotating groove of the connecting block 201 to realize the folding action of the filter screen 1. After folding in place, release the button 205. The spring 203 resets and pushes the limiting plate 202, so that the locking block 204 is re-locked into the corresponding locking groove, completing the positioning and fixing after folding. The second step: The mixing assembly 3 consists of a first mixing rod 301, a second mixing rod 302, and a third mixing rod 303. The components are connected by the engagement of a threaded rod 304 and a threaded groove. During disassembly, the connection between the first mixing rod 301 and the second mixing rod 302 is rotated to separate the threaded groove at the top of the first mixing rod 301 from the threaded rod 304 at the bottom of the second mixing rod 302. Similarly, the connection between the second mixing rod 302 and the third mixing rod 303 is rotated to separate them. The cross-shaped mixing head 305 is disassembled in the same way as the first mixing rod 301. By rotating it, the threaded groove at the top of the cross-shaped mixing head 305 is separated from the threaded rod 304 at the bottom of the first mixing rod 301. After disassembly, the components can be stored separately, significantly reducing the storage volume and making it easy to carry in the field.
