Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of soil layer measurement, and in particular relates to a soil layer thickness measuring device. Background Art
[0002] A soil layer is a layer of soil that is roughly parallel to the ground in a soil profile. Each soil layer differs from the soil layers above and below it in color, structure, type and quantity of organisms, reflecting the differences in biological characteristics of each soil layer. Soil layer thickness measurement is a type of land surveying and mapping work. When measuring soil layer thickness, it is necessary to sample and measure the soil. When sampling, the existing sampling device needs to insert the sampling device into the soil, and then take out the soil sample, so that the thickness of the soil layer can be measured through the soil sample. However, when sampling, the soil in contact with the sampling device will be displaced by the sampling device, which will cause the boundaries between soil layers in the soil sample to be blurred, which will affect the accuracy of soil layer measurement.

[0017] See also Figure 1-Figure 5 The utility model provides the following technical solution: it includes an outer cylinder 1, which is characterized in that: a hollow groove 11 is opened on the side wall of the outer cylinder 1, and two connecting plates 2 are slidably connected to the inner side of the hollow groove 11, and a soil sample collecting groove 3 for collecting soil samples is slidably connected to the inner side of the two connecting plates 2, and the bottom of the soil sample collecting groove 3 is an oblique angle, and a movable push rod 4 for pushing the soil sample collecting groove 3 is movably connected to the inner side of the outer cylinder 1, and the bottom of the movable push rod 4 is conical.
[0018] In this embodiment: it includes an outer cylinder 1, which is relatively long and has a thin side wall, so that the outer cylinder 1 can be easily inserted into the soil. An empty groove 11 is provided on the side wall of the outer cylinder 1. Two connecting plates 2 are slidably connected to the inner side of the empty groove 11. The two connecting plates 2 are positioned opposite to each other and there is a gap between the two connecting plates 2. When the outer cylinder 1 is inserted into the soil, the connecting plates 2 will enter the soil along with the outer cylinder 1. A soil sample collecting groove 3 for collecting soil samples is slidably connected to the inner side of the two connecting plates 2. The shape of the soil sample collecting groove 3 is relatively flat, and the soil sample collecting groove 3 is slidably connected between the two connecting plates 2. The bottom of the soil sample collecting groove 3 is an oblique angle, and the rear side of the soil sample collecting groove 3 is an arc. Since the bottom of the soil sample collecting trough 3 is at an oblique angle, when the outer cylinder 1 enters the soil, the soil sample collecting trough 3 will also be inserted into the soil. The inner side of the outer cylinder 1 is movably connected with a movable push rod 4 for pushing the soil sample collecting trough 3, and the bottom of the movable push rod 4 is conical. When the outer cylinder 1 and the soil sample collecting trough 3 sink, the soil sample collecting trough 3 is located on the inner side of the outer cylinder 1, thereby preventing the disturbed soil from entering the soil sample collecting trough 3 during the sinking process. By placing the tip of the movable push rod 4 on the inner side of the outer cylinder 1 and the end of the movable push rod 4 on the rear side of the soil sample collecting trough 3, and then pressing the movable push rod 4 downward, the movable push rod 4 enters the outer cylinder 1 The movable push rod 4 can push the soil sample collecting groove 3 to the outside of the outer cylinder 1, so that the soil sample collecting groove 3 can collect the soil layer at a certain distance from the outer cylinder 1 in a horizontal direction, which is beneficial to ensure the integrity of the soil layer and avoid the situation where the position of the soil layers is changed due to the influence of the sampling device on the soil sample taken out, which affects the measurement of the soil layer thickness, and is beneficial to improve the measurement accuracy. The soil sample collecting groove 3 can collect the soil layer in a horizontal direction through the push of the movable push rod 4, so that the soil sample collecting groove 3 can collect the soil sample at a certain distance from the insertion position of the outer cylinder 1, thereby reducing the influence of the movement of the outer cylinder 1 on the soil sample. When in use, first The outer cylinder 1 is inserted into the soil, and the connecting plate 2 and the soil sample collecting groove 3 are also inserted into the soil, and the tops of the outer cylinder 1 and the soil sample collecting groove 3 are higher than the ground level. Then the tip of the movable push rod 4 is placed on the inner side of the outer cylinder 1, and the end of the movable push rod 4 is located on the rear side of the soil sample collecting groove 3. Then the movable push rod 4 is pressed downward to make the movable push rod 4 enter the inner side of the outer cylinder 1, so that the movable push rod 4 can push the soil sample collecting groove 3 to the outside of the outer cylinder 1, so that the soil sample collecting groove 3 can collect the soil layer at a certain distance from the outer cylinder 1 in a horizontal direction. Finally, the outer cylinder 1 and the soil sample collecting groove 3 are pulled out upward, so that the soil layer thickness of the soil sample inside the soil sample collecting groove 3 can be measured.
[0019] Two connecting grooves 111 are provided on the inner side of the empty groove 11, and a connecting block 21 is provided on one side of each of the two connecting plates 2. The connecting block 21 is slidably connected to the inner side of the connecting groove 111; the connecting block 21 is connected to the connecting groove 111, so that the connecting plate 2 and the outer cylinder 1 can be connected, and the connecting plate 2 can be connected to the outer cylinder 1 by sliding the connecting block 21 upward from the bottom of the connecting groove 111.
[0020] The connecting plate 2 has the same length as the outer cylinder 1, and a plurality of second connecting grooves 22 are provided on the side of the connecting plate 2 away from the outer cylinder 1; the connecting block 1 21 is parallel to the connecting plate 2 and the outer cylinder 1, and the second connecting grooves 22 are horizontal.
[0021] A plurality of connecting blocks 31 are provided on the outer side of the soil sample collecting trough 3, and the connecting blocks 31 are slidably connected to the inner side of the connecting groove 22; through the connection between the connecting blocks 31 and the connecting groove 22, the soil sample collecting trough 3 can slide horizontally, so that the soil can be sampled horizontally.
[0022] A control block 41 is provided on the top of the movable push rod 4, and the movable push rod 4 matches the size of the outer cylinder 1; the diameter of the control block 41 is larger than the diameter of the outer cylinder 1, thereby preventing the movable push rod 4 from completely entering the interior of the outer cylinder 1 and being unable to be pulled out upwards. Since the movable push rod 4 matches the size of the outer cylinder 1, when the movable push rod 4 enters the interior of the outer cylinder 1, the soil sample collecting trough 3 can be pushed out a longer distance.
[0023] The working principle and use process of the utility model are as follows: when in use, the outer cylinder 1 is first inserted into the soil, and the connecting plate 2 and the soil sample collecting groove 3 are also inserted into the soil, and the tops of the outer cylinder 1 and the soil sample collecting groove 3 are higher than the height of the ground, and then the tip of the movable push rod 4 is placed on the inner side of the outer cylinder 1, and the end of the movable push rod 4 is located on the rear side of the soil sample collecting groove 3, and then the movable push rod 4 is pressed downward to make the movable push rod 4 enter the inner side of the outer cylinder 1, so that the movable push rod 4 can push the soil sample collecting groove 3 to the outside of the outer cylinder 1, so that the soil sample collecting groove 3 can collect the soil layer at a certain distance from the outer cylinder 1 in a horizontal direction, and finally the outer cylinder 1 and the soil sample collecting groove 3 are pulled out upward, so that the soil layer thickness of the soil sample inside the soil sample collecting groove 3 can be measured.
