DETAILED DESCRIPTION

[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0027] See also Figures 1 to 6 A device for automatically screening soil geochemical samples comprises a housing 1, a screening mechanism 2, and a drive mechanism 3. Two screening mechanisms 2 are mounted within the housing 1, one above the other. Two drive mechanisms 3 are mounted within the housing 1, one below the other. Two outlets 4 are located on the left side of the housing 1, corresponding to the two screening mechanisms 2.

[0028] The drive mechanism 3 includes a motor housing 301, which is fixedly connected to the right side of the housing 1. A motor 302 is fixedly connected to the interior of the motor housing 301. A T-shaped fixing plate 303 is fixedly connected to the right inner wall of the housing 1. The output end of the motor 302 is fixedly connected to a rotating rod 304. The left end of the rotating rod 304 passes through the right side of the housing 1 and extends into the interior of the T-shaped fixing plate 303. A circular disc 305 is fixedly connected to the left end of the rotating rod 304, and the rotating rod 304 is offset from the center of the circular disc 305. A connecting block 306 is provided inside the T-shaped fixing plate 303. A connecting rod 307 is fixedly connected to the right side of the connecting block 306. A roller 308 is rotatably connected to the right end of the connecting rod 307. Roller 308 is rotatably connected to the inner wall of disk 305. A driving slide 309 is fixedly connected to the upper surface of connecting block 306. The upper end of driving slide 309 slides through the inner top wall of T-shaped fixing plate 303 and extends above T-shaped fixing plate 303. Return spring 1 310 is sleeved on the outer surface of driving slide 309 and is located between T-shaped fixing plate 303 and connecting block 306. A limit slide 312 is fixedly connected to the inner top wall of T-shaped fixing plate 303. A limit plate 311 is fixedly connected to the side of connecting block 306, and limit plate 311 is slidably connected to the surface of limit slide 312.

[0029] The two screening mechanisms 2 are configured to achieve multi-stage screening of soil samples. The operation of the drive mechanism 3 is controlled by an external control switch, which can cause the screening mechanism 2 to vibrate continuously. When the external control switch activates the motor 302, the rotating rod 304 connected to its output end rotates accordingly. Since the rotating rod 304 deviates from the center of the disc 305, the rotation of the rotating rod 304 causes the disc 305 to undergo eccentric motion. This is then converted into reciprocating linear motion of the connecting block 306 through the rolling contact between the roller 308 and the disc 305, in conjunction with the limit plate 311 and the limit slide 312. With the cooperation of the return spring 1 310, this drives the drive slide 309 on the connecting block 306 to continuously slide up and down within the T-shaped fixed plate 303. The cooperation between the limit plate 311 and the limit slide 312 ensures that the drive slide 309 maintains a certain degree of stability during the rising and falling processes.

[0030] The screening mechanism 2 includes a mounting plate 201, which is positioned within the housing 1. A rotating shaft 202 is mounted on the left end of the mounting plate 201, which is rotatably connected to the surface of the outlet 4 via the rotating shaft 202. A U-shaped fixing plate 203 is fixedly connected to the right inner wall of the housing 1, and the right end of the mounting plate 201 is positioned within the U-shaped fixing plate 203. Multiple return springs 204 are fixedly connected to the upper surface of the mounting plate 201, located within the U-shaped fixing plate 203. The upper ends of the multiple return springs 204 are fixedly connected to the inner top wall of the U-shaped fixing plate 203. A screen 205 is mounted on the surface of the mounting plate 201. A T-shaped fixing plate 303 is positioned below the U-shaped fixing plate 203, and the upper end of the driving slide 309 is in contact with the bottom surface of the mounting plate 201.

[0031] The upper end of the drive slide 309 engages the bottom surface of the mounting plate 201. As the drive slide 309 reciprocates, it pushes the mounting plate 201 to oscillate slightly around the rotation axis 202 within the U-shaped fixing plate 203, causing the screen 205 on the mounting plate 201 to vibrate. The soil sample is gradually separated by the vibrations on the screen 205. The screens 205 in the two screening mechanisms 2 have different densities, allowing soil particles of different sizes to be screened out on their respective screens 205.

[0032] Two discharge frames 5 are fixedly attached to the left side of the box 1, corresponding to the two outlets 4. With the cooperation of the outlets 4 and the discharge frames 5, soil samples of different particle sizes are discharged through their respective outlets 4, and the discharge frames 5 serve as guides to facilitate soil sample collection. A feed hopper 6 is mounted on the top surface of the box 1, and an observation window 7 is provided on the front of the box 1. The feed hopper 6 facilitates the pouring of soil samples into the interior of the box 1, and the observation window 7 allows the interior of the box 1 to be observed.

[0033] A collection frame 8 is provided inside the housing 1. This frame is located at the bottom of the housing 1. Slideways 9 are provided on the left and right inner walls of the housing 1. Slide bars 10 are connected to the left and right sides of the collection frame 8. The two slide bars 10 slide into the interiors of the two slide bars 9, respectively. A handle 11 is fixedly connected to the front of the collection frame 8. The collection frame 8 is used to collect even the smallest soil samples that escape from the screening mechanism 2, ensuring that all soil samples are effectively collected. By pulling the handle 11, the collection frame 8 can be quickly pulled out with the cooperation of the slide bars 9 and slide bars 10.

[0034] The bottom surface of the box body 1 is fixedly connected with four support legs 12, which are respectively distributed in a rectangular shape on the bottom surface of the box body 1. The support legs 12 provide stable support for the entire device, so that the device can maintain a stable working state during operation.

[0035] Working principle: When the device is in use, the motor 302 is started by an external control switch, and the disc 305 is driven to rotate eccentrically through the rotating rod 304. Under the cooperation of the T-shaped fixed plate 303, roller 308, connecting rod 307, connecting block 306, return spring 1 310, limit plate 311 and limit slide bar 312, the driving slide bar 309 is driven to slide back and forth up and down, and then, through the cooperation of return spring 204, the mounting plate 201 is pushed to swing continuously and slightly around the rotating shaft 202 in the U-shaped fixed plate 203, thereby driving the screen 205 to shake, and then the soil sample to be processed is slowly poured from the feed hopper 6 into the box 1. The soil samples of different specifications and densities and different particle sizes of the two screens 205 will be discharged through their respective outlets. The soil samples are collected through the guidance of the discharge frame 5, and the finest soil samples fall into the collection frame 8. By pulling the handle 11, the collection frame 8 can be quickly pulled out under the cooperation of the slide groove 9 and the slide bar 10.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
