It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model embodiment provides a soil impurity removal device for soil testing, such as... Figures 1-5 As shown, the system includes a soil cleaning box 1. A motor 2 is bolted to one outer wall of the soil cleaning box 1. A rotating drum 3 is bolted to one output end of the motor 2. A sweeping plate 4 is welded to the inner wall of the rotating drum 3. An air nozzle 5 is bolted to the inner wall of the soil cleaning box 1 on the side away from the motor 2. A high-pressure air pump 6 is bolted to the top of the soil cleaning box 1. A connecting pipe 7 is bolted between the output end of the high-pressure air pump 6 and the air nozzle 5. The bottom of the air nozzle 5 fits snugly against the outer wall of the rotating drum 3. Both the air nozzle 5 and the high-pressure air pump 6 are connected to the connecting pipe 7. A soil collecting cover 8 is welded to one inner wall of the soil cleaning box 1 near the inner side of the rotating drum 3. A soil discharging cover 9 is welded to one side of the soil collecting cover 8. The cross-sections of the soil collecting cover 8 and the soil discharging cover 9 are shown. All are isosceles trapezoids, and the outer wall of the soil collection hood 8 is provided with sieve holes. The soil discharge hood 9 passes through the soil impurity removal box 1, and the outer wall of the soil discharge hood 9 away from the soil collection hood 8 is hinged with a door 10. The inner wall of the soil impurity removal box 1 is fixedly connected to an inclined guide plate 11 by bolts near the lower part of the soil collection hood 8. The outer wall of the soil impurity removal box 1 away from the motor 1 2 is fixedly connected to a motor 2 12 by bolts. The output end of the motor 2 12 is fixedly connected to a rotating rod 13. The outer wall of the rotating rod 13 is welded with an impact plate 14. The outer wall of the soil impurity removal box 1 is hinged to a box door 15 and a cylinder door 16 near the lower part of the motor 1 2. The box door 15 is located below the cylinder door 16. The outer walls of the soil impurity removal box 1 and the rotating cylinder 3 are both provided with through slots near the cylinder door 16.

[0023] It needs to be explained that, due to the fact that some soils contain more moisture, the moist soil is easy to block the filter screen during the impurity removal process, thereby causing the problem of poor impurity removal effect. Some soil impurity removal devices will dry the soil by heating. Since the soil detection project also detects the organic matter content of the soil, using the heating method is easy to cause significant damage to the organic matter, thereby causing the problem of inaccurate detection results. In the embodiment, the high-speed airflow is blown towards the rotating drum 3, which can blow out the moist soil blocked in the screen holes on the drum 3, realize screen hole cleaning of the drum 3, not only ensure the smoothness of the screen holes to avoid blockage, but also realize the collection of moist soil, without using the heating method to dry the soil, thereby avoiding damage to the soil organic matter and ensuring the accuracy of the soil organic matter detection results. The soil falling under the impact plate 14 is scattered by the impact force, which facilitates the separation of soil and sand and leaves, thereby facilitating subsequent rapid impurity removal operation.

[0024] Specifically, in the embodiment, the scheme mainly includes the drum 3, the air jet nozzle 5, the soil collecting cover 8, the inclined guide plate 11 and the rotating rod 13. When impurities are removed before soil detection, the drum door 16 is opened, the drum 3 is exposed, and the soil that has not been removed is poured into the inside of the drum 3. At this time, the control motor one 2 drives the drum 3 to rotate through the output end on one side thereof. The sweep plate 4 on the inner side wall of the drum 3 moves axially and circumferentially. The sweep plate 4 sweeps the soil. The smaller soil particles pass through the screen holes on the drum 3 and fall to the bottom inside the soil impurity removal box 1. Part of the moist soil is blocked in the screen holes on the drum 3. The sweep plate 4 sweeps the unfiltered soil upwards. When the sweep plate 4 is inclined, the unfiltered soil on the sweep plate 4 flows onto the inclined guide plate 11. Under the inclined guidance of the inclined guide plate 11, the unfiltered soil falls above the rotating rod 13. The control motor two 12 drives the rotating rod 13 to rotate at high speed through the output end on one side thereof. The impact plate 14 on the rotating rod 13 moves synchronously at high speed. The impact plate 14 impacts the falling soil and scatters the caked soil by the impact force, which facilitates the separation of soil and sand and leaves. When the blocked screen holes on the drum 3 move to the position directly below the air jet nozzle 5, the high-pressure air pump 6 sprays high-speed airflow towards the screen holes on the drum 3 through the air jet nozzle 5. The moist soil blocked in the screen holes is blown out by the airflow, which ensures the smoothness of the screen holes. The moist soil blown out is collected by the soil collecting cover 8. After the soil impurity removal is completed, the cover door 10, the box door 15 and the drum door 16 are opened. The soil inside the soil collecting cover 8 and the soil impurity removal box 1 is scraped out by using a tool, and the small stones and leaves in the drum 3 are taken out.

[0025] As shown in the further preferred embodiment of the utility model, Figure 3 The drum 3 is a hollow cylindrical structure with one side open, and screen holes are formed on the outer side wall of the drum 3.

[0026] In the embodiment, the open design of the rotating drum 3 on one side can make the rotating drum 3 not interfere with the soil collecting cover 8, the inclined guide plate 11 and the rotating rod 13 when rotating, ensure smooth rotation of the rotating drum 3, and realize the filtration of small stones and leaves in the soil through the sieve holes.

[0027] As shown in the further preferred embodiment of the utility model, Figure 3 and Figure 5 The angle between the inclined guide plate 11 and the horizontal plane is 45 degrees, and one side end of the inclined guide plate 11 is located above the side of the rotating rod 13.

[0028] In the embodiment, the 45-degree inclined guide plate 11 can make the unfiltered soil fall above the rotating rod 13.
