Inside the device body 1, there is a crushing component 3 capable of crushing the sample. Inside the device body 1, there is a screening component 4 capable of vibrating up and down to screen the crushed sample. On the inner wall of the device body 1, there is a limiting component 5 capable of limiting the screening component 4. On one side of the surface of the device body 1, there is a power component 2 capable of promoting the up and down vibration of the screening component 4 and the operation of the crushing component 3. Driving the crushing component 3 to work through the power component 2 can crush the soil sample so that the soil particles and soil lumps in the sample can be removed. And after the sample is crushed, it will enter the screening component 4, and then the power component 2 drives the screening component 4 to vibrate so as to achieve the effect of screening the soil sample. Finally, the screened sample is discharged through the discharging pipe 7 for detection, thus avoiding the problem that the unevenness of the sample after crushing affects the detection result.

[0025] As Figure 2 and Figure 4 shown, the crushing component 3 includes a crushing box 301. The four sides of the surface of the crushing box 301 are fixedly connected to the inner wall of the device body 1. The top surface of the crushing box 301 is provided with a feeding port 302, and the feeding port 302 is communicated with the feeding pipe 6. The bottom surface of the crushing box 301 is provided with a discharging port 305. The crushing component 3 further includes two rolling wheels 303 capable of crushing the sample. One ends of the two rolling wheels 303 are respectively rotatably connected to one side of the inner wall of the crushing box 301. The other ends of the two rolling wheels 303 respectively penetrate through one side of the inner wall of the crushing box 301 and extend to one side of the surface of the device body 1. One ends of the two rolling wheels 303 extending to one side of the surface of the device body 1 are fixedly connected with transmission gears 304. The opposite sides of the two transmission gears 304 are meshed with each other, so that the two rolling wheels 303 can rotate in different directions to crush the sample.

[0026] As Figure 2 and Figure 5 shown, the limiting component 5 includes two limiting grooves 501 respectively opened on the opposite sides of the inner wall of the device body 1. The inner walls of the two limiting grooves 501 are both slidably connected with limiting blocks 502.

The opposite sides of the surface of the screening frame 401 are respectively fixedly connected to the opposite sides of two limit blocks 502. The bottom surface of the screening frame 401 is fixedly connected with a screening mesh 403. The screening mesh 403 can screen the sample to improve the particle size uniformity of the crushed sample. At the center of the bottom surface of the screening frame 401, two baffles 402 are fixedly connected. The two baffles 402 can prevent the sample from falling on the bi-directional reciprocating lead screw 405 during screening and affect the normal operation of the bi-directional reciprocating lead screw 405. The opposite sides of the two baffles 402 are jointly fixedly connected with a control board 404. The screening assembly 4 further includes a bi-directional reciprocating lead screw 405 and a guide rod 408 fixedly connected to the opposite side of the inner wall of the device body 1. One end of the bi-directional reciprocating lead screw 405 is rotatably connected to one side of the inner wall of the device body 1, and the other end of the bi-directional reciprocating lead screw 405 penetrates through one side of the inner wall of the device body 1 and extends to the surface side of the device body 1. Two moving blocks 406 are threadedly connected to the rod wall of the bi-directional reciprocating lead screw 405. Both of the two moving blocks 406 are sleeved on the rod wall of the guide rod 408 and the inner walls of the two moving blocks 406 are slidably connected to the rod wall of the guide rod 408. The top surfaces of the two moving blocks 406 are rotatably connected with pulleys 407. The pulleys 407 cooperate with the control board 404 so as to achieve the effect that the screening frame 401 can vibrate as the moving blocks 406 move.

[0028] As Figure 1 and Figure 2 shown in the figure, the power assembly 2 includes a mounting plate 201. One side of the mounting plate 201 is fixedly connected to one side of the surface of the device body 1. The top surface of the mounting plate 201 is fixedly connected with a motor 202.

A transmission belt 204 is jointly meshed and connected to the surfaces of the second synchronous gear 205 and the first synchronous gear 203.

[0029] As Figure 2 shown in the figure, the bottom surface of the device body 1 is inclined and inclined towards the discharge pipe 7, which is convenient for taking out the screened sample.

[0030] As Figure 2 and Figure 5 shown in the figure, the bottom surface of the control board 404 is wavy, so that it can drive the screening frame 401 to vibrate as the two moving blocks 406 move. The top surface of the control board 404 is flush with the top surface of the screening mesh 403.

[0031] Working principle of the utility model: When the device is in use, first connect the motor 202 to an external power supply, and then place the soil sample to be crushed from the feeding pipe 6 so that the soil sample enters the inside of the crushing box 301. Then, through the cooperation of the first synchronous gear 203, the second synchronous gear 205 and the transmission belt 204, the motor 202 can drive one of the transmission gears 304 to rotate, and then the other transmission gear 304 also rotates, so that the two rolling wheels 303 can rotate in different directions to crush the soil sample.

[0032] When the soil sample is crushed, it will enter the inside of the screening frame 401 through the feeding port 305 at the bottom of the crushing box 301. Then, the double-direction reciprocating screw rod 405 rotates through the rotation of the first synchronous gear 203. Then, with the rotation of the double-direction reciprocating screw rod 405, the two moving blocks 406 move rapidly back and forth on the double-direction reciprocating screw rod 405, and while the two moving blocks 406 are reciprocating, they can drive the screening frame 401 and the sample in the screening frame 401 to move up and down by cooperating with the control board 404, so as to screen the soil sample through the screening mesh 403. Then, the screened soil sample is discharged through the discharge pipe 7 to obtain a soil sample with uniform particle size. Finally, after the screening work is completed, open the box door 8 to clean the remaining sample in the screening frame 401. The original text highlights the innovative structure and does not elaborate too much on the prior art.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
