[0002] Soil erosion is one of the major environmental problems facing the world today, and it has had a profound impact on agriculture, forestry, water conservancy and the ecological environment. The sand content in the soil is one of the important indicators for measuring the degree of soil erosion. Therefore, accurate and timely monitoring of the sand content in the soil is of vital importance for assessing the status of soil erosion and formulating prevention and control measures.

[0003] A search revealed that Chinese patent CN218726335U discloses a device for monitoring the sand content in foundation pit pumping water. By setting up an inlet valve and a drain valve, and connecting the inlet pipe and the drain, the device can be used for convenient testing.

[0004] The aforementioned sand content monitoring device uses a method of sampling, then adding water and stirring to separate the sand. The sand content is monitored by comparing the weight of the filtered sand with the weight of the original sample. The design flaw is that the shell is fixed and inconvenient to remove and carry. This requires the collected sample to be carried to the laboratory, weighed, and then placed inside the shell. The water pipe structure also makes it inconvenient to move the entire sand content monitoring device. In addition, the rotation speed of the sample inside the sand separation cylinder is slow, resulting in low sand separation efficiency. Utility Model Content

An arc-shaped clamping plate for clamping the sand separation cylinder is provided on the inner side of the vertical rod. A limiting rod is fixedly connected to the outer wall of the arc-shaped clamping plate in the horizontal direction. One end of the limiting rod extends to the outside of the vertical rod, and a first screw is horizontally connected to the outer wall of the arc-shaped clamping plate below the limiting rod. A first handwheel is fixedly connected to the first screw extending to the outside of the vertical rod.

[0009] As a further improvement to the technical solution of this utility model, the inner wall of the arc-shaped clamp is bonded with a rubber pad, and the outer wall of the arc-shaped clamp is provided with a bearing seat at the end position of the first screw.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model places the sand separation cylinder inside the placement cylinder and uses two clamping components to clamp and fix the sand separation cylinder. During operation, rotating the first handwheel drives the first screw to rotate.

[0027] Working principle: This utility model designs a sand content monitoring device for soil erosion, the specific structure of which is shown in the attached instruction manual. Figure 1-5As shown, in this technical solution, the soil or mud at the location to be tested is weighed and loaded into the sand separation cylinder 8. Then, after the sand separation cylinder 8 is installed inside the placement cylinder 7, water is injected into the sand separation cylinder 8 so that the water level is not lower than 2 / 3 of the sand separation cylinder 8. The sand separation cylinder 8 is clamped and fixed using two clamping components. During operation, rotating the first handwheel 12 drives the first screw 11 to rotate. The arc-shaped clamping plate 10 is guided and limited by the limiting rod 13 to maintain horizontal movement until it clamps the sand separation cylinder 8, so that the sand separation cylinder 8 and the placement cylinder 7 are kept in a stable state. By setting the stirring shaft 19, the second motor 20, and the lifting plate 18, and by setting the lifting drive mechanism, during use, rotating the second handwheel 24 drives the second screw 23 to rotate. The L-shaped plate 17 is limited by the column 16 to maintain verticality. The upward stable movement drives the lifting plate 18 to rise and fall vertically. Then, the lifting plate 18 is lowered, driving the stirring shaft 19 to fall into the sand separation cylinder 8. At this time, the first motor 4 and the second motor 20 are started, with the same driving direction. The first motor 4 drives the placement cylinder 7 and the sand separation cylinder 8 to maintain high-speed rotation, and the second motor 20 controls the stirring shaft 19 to continue rotating, thereby improving the rotation efficiency of the sample inside the sand separation cylinder 8, so that the mud and sand inside are separated. The sand at the separation point is retained on the filter screen 801. After the separation is completed, the sand separation cylinder 8 is taken out, the drain port 802 is opened to drain the mud and water at the bottom, and then the sand on the filter screen 801 is removed, dried, and weighed. By comparing the weight of the mud or soil in the unseparated state, the sand content of the mud or mud at the test location can be monitored.
