[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0024] In the drawings, the same reference numerals all refer to the same components.

[0025] Example 1

[0026] like Figures 1-4 As shown, the utility model provides a soil sample pretreatment device, including a receiving component 1 and a crushing component 2, the receiving component 1 includes a receiving bin 11, and support plates 12 are fixedly arranged on the left and right sides of the inner wall of the receiving bin 11, a spring 13 is welded to the top of the support plate 12, a pad 14 is fixedly arranged on the top of the spring 13, a threaded rod 15 is welded to the top of the pad 14, and a ram's horn nut 16 is connected to the external thread of the threaded rod 15.

[0027] The crushing assembly 2 includes a crushing barrel 21, and a docking assembly 22 is fixedly arranged on the outside of the crushing barrel 21. The docking assembly 22 includes a docking ring 221 fixedly arranged on the outside of the crushing barrel 21. A through hole 222 for inserting the threaded rod 15 is opened inside the docking ring 221. The outer diameter of the ram's horn nut 16 is larger than the diameter of the through hole 222, and the ram's horn nut 16 is located above the through hole 222. A sleeve 223 is bonded to the outside of the docking ring 221. The sleeve 223 is for being sleeved on the outside of the receiving bin 11 to prevent the soil powder in the receiving bin 11 from floating out. The sleeve 223 adopts an elastic rubber sleeve.

[0028] A sealing door 23 is provided on the top of the pulverizing barrel 21, which can be opened and closed. A first filter plate 24, a second filter plate 25 and a pulverizing motor 26 are arranged in intervals from top to bottom inside the pulverizing barrel 21. A positioning rod 261 fixedly connected to the inner wall of the pulverizing barrel 21 is fixedly provided on the outside of the pulverizing motor 26. A first filter hole is provided on the first filter plate 24, and a second filter hole is provided on the second filter plate 25. The inner diameter of the first filter hole is larger than the inner diameter of the second filter hole. A rotating rod 27 is fixedly provided on the output end of the pulverizing motor 26, which passes through the second filter plate 25 and the first filter plate 24 in sequence and extends to the top of the first filter plate 24. A breaking piece 28 and a cutting knife 29 made of tungsten-cobalt alloy are welded to the outside of the rotating rod 27. The cutting knife 29 is located between the first filter plate 24 and the second filter plate 25, and the breaking piece 28 is located above the first filter plate 24.

[0029] It should be noted that the individual soil samples obtained by sampling do not need to be completely crushed and screened out. Turning on the equipment for five minutes is sufficient to obtain a powdered sample sufficient for testing. After each use of the equipment, the receiving component 1 and the crushing component 2 are separated by twisting off the clevis nut 16, and then the receiving component 1 and the crushing component 2 are rinsed separately.

[0030] In addition, the crushing member 28 includes a U-shaped seat 281 and a swing rod 282. The U-shaped seat 281 is fixedly arranged on the outside of the rotating rod 27, and the swing rod 282 is hinged on the U-shaped seat 281. After the rotating rod 27 is driven by the crushing motor 26 to start rotating, the swing rod 282 hammers and crushes the dry soil sample in the crushing cylinder 21.

[0031] In summary, the utility model sets a crushing component 2, puts the dry soil sample into the crushing cylinder 21, and the crushing piece 28 crushes the soil sample. The stones and some plant roots that cannot be crushed are left on the first filter plate 24, and the soil sample with smaller particles enters the bottom of the first filter plate 24. The cutting knife 29 cuts and crushes the fallen fine soil blocks, and the soil sample with qualified fineness falls from the second filter plate 25 into the receiving component 1. In this way, there is no need to manually select debris such as stones and plant roots in the soil sample, which greatly saves the time of the staff. By setting the receiving component 1, when performing crushing and screening, the crushing component 2 is set on the receiving component 1. After the crushing motor 26 on the crushing component 2 is turned on, the crushing component 2 starts to shake, and the spring 13 stretches, twists and shakes accordingly. The soil on the first filter plate 24 and the second filter plate 25 can be screened faster, with a partial vibrating screen effect.

[0032] 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, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
