[0017] Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] As Figures 1-3 shown, a field automatic screening device for soil geochemical measurement samples includes a box body 1. A filter hopper 2 is arranged on the upper side inside the box body 1. A first filter plate 3 is embedded in the middle part of the filter hopper 2. A first driving member 4 is installed on the top of the box body 1. The driving end of the first driving member 4 penetrates through the inner wall of the top of the box body 1 and is connected to a vertically arranged rotating plate 5. A feeding hopper 6 is arranged on one side of the box body 1. Two upper and lower discharge ports are opened on the other side of the box body 1. A second filter plate 23 and a third filter plate 7 are obliquely arranged at intervals up and down inside the box body 1.

[0019] Both sides of the bottom of the second filter plate 23 and the third filter plate 7 are connected to the inner wall of the box body 1 through vertical springs respectively. One end of the second filter plate 23 penetrates through the upper discharge port, and one end of the third filter plate 7 penetrates through the lower discharge port. A collecting assembly is connected to the other side of the box body 1 by screws. The bottom of the second filter plate 23 is placed on the first cam 22, and the bottom of the third filter plate 7 is placed on the second cam 8. The first cam 22 and the second cam 8 are respectively rotationally connected to the inner walls of the front and rear sides of the box body 1 through rotating shafts.

[0020] A second driving member 9 is installed at the front end of the box body 1. The second driving member 9 is connected to the two rotating shafts through a synchronous pulley and a synchronous belt. A first collecting tank 10 is arranged at the lower side inside the box body 1.

[0021] The collecting assembly includes a collecting bin 11. The collecting bin 11 is detachably installed on one side of the discharge port of the box body 1 by screws. Two second collecting tanks 12 and a third collecting tank 21 are arranged horizontally side by side on the lower side of the collecting bin 11. The third collecting tank 21 near the discharge port corresponds to the lower discharge port, and the second collecting tank 12 far from the discharge port corresponds to the upper discharge port. A guide plate 13 is arranged at the top of the third collecting tank 21 near the discharge port, which is used to separate the materials coming out of the two discharge ports and guide them into the second collecting tank 12 and the third collecting tank 21 respectively.

[0022] A first opening and closing door 17 is arranged at the front end of the first collecting tank 10, and fourth opening and closing doors 20 are arranged at the front ends of the filter hoppers 2. A second opening and closing door 18 is arranged at the front end of the second collecting tank 12, and a third opening and closing door 19 is arranged at the front end of the third collecting tank 21.

[0023] In the field, after the operator finishes collecting soil geochemical measurement samples, the samples can be put into the interior of the box body 1 through the feeding hopper 6. At the same time, the collecting bin 11 is connected to the box body 1 by screws. Subsequently, the samples are preliminarily filtered by the first filter plate 3 in the middle of the filtering hopper 2. Since there may be impurities such as branches and leaves in the samples, it is easy to cause blockage of the first filter plate 3. At this time, the first driving member 4 is controlled to drive the rotating plate 5 to rotate. Since the material enters laterally, the rotating plate 5 can flatten the material accumulated on the first filter plate 3 during rotation, thereby preventing blockage of the first filter plate 3.

[0024] Subsequently, the second driving member 9 is controlled to operate. The second driving member 9 can drive the first cam 22 and the second cam 8 to rotate simultaneously through the cooperation of synchronous wheels, synchronous belts and rotating shafts. The first cam 22 and the second cam 8 cooperate with springs to vibrate the second filter plate 23 and the third filter plate 7 inside the box body 1 and perform efficient screening operations on the samples. At this time, the larger particle samples will be discharged through the upper discharge port along with the vibration of the second filter plate 23, the medium particle samples will be discharged through the lower discharge port along with the vibration of the third filter plate 7, and the finer particle samples will enter the first collection tank 10 inside the lower side of the box body 1. The combined driving structure of cams, synchronous wheels and synchronous belts is used to realize the simultaneous vibration of the second filter plate 23 and the third filter plate 7, which has a lower cost compared to separately equipped with two vibration motors.

[0025] The guide plate 13 inside the collecting bin 11 separates the upper and lower discharge ports of the box body 1. Furthermore, the larger particles screened out by the second filter plate 23 on the upper side will be discharged through the upper discharge port, enter the second collection tank 12 through the inside of the collecting bin 11, and the medium particles screened out by the third filter plate 7 on the lower side will enter the third collection tank 21 through the inside of the collecting bin 11.

[0026] After the screening is completed, the first opening and closing door 17 at the front end of the first collection tank 10, the second opening and closing door 18 at the front end of the second collection tank 12, and the third opening and closing door 19 at the front end of the third collection tank 21 can be opened. Among them, the second opening and closing door 18 is used to take large materials, the third opening and closing door 19 is used to take medium materials, and the first opening and closing door 17 is used to take fine materials, so as to realize the separate collection of samples with different particle sizes after screening; since there are impurities in the samples that cannot be filtered, the fourth opening and closing door 20 at the front end of the filtering hopper 2 can be opened and the impurities can be taken out.

[0027] A support frame 14 is arranged outside the first driving member 4, which can protect the first driving member 4. A handle 15 is rotatably connected to the upper side of the support frame 14 and can provide support for the handle 15 at the same time. The operator can conveniently move the box body 1 through the handle 15, which is convenient for the operator to carry.

[0028] There are two sealing plates 16 rotatably connected inside the feeding hopper 6. The lower side of the sealing plate 16 is connected to the inner wall of the feeding hopper 6 through a spring. The sealing plate 16 cooperates with the spring to keep the feeding hopper 6 sealed, thereby preventing dust from flying during the sample screening process and affecting the health of surrounding operators. When samples are put into the feeding hopper 6, the two sealing plates 16 will separate under the gravity of the samples to achieve smooth feeding.

[0029] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
