Description

Technical Field

[0001] This utility model belongs to the technical field of soil sampling equipment, specifically relating to an environmental engineering soil sampling device. Background Technology

[0002] When conducting soil sampling in environmental engineering, soil samplers are often used. Soil samplers can truly meet the requirements of full-layer, equal-volume, and convenient soil sampling, solving the problem of accurately collecting soil samples that is difficult to achieve in soil and fertilizer work such as soil testing and fertilizer recommendation, and soil monitoring.

[0003] Existing soil samplers are mostly composed of a sampling tube, an outer cylinder, a bulldozer, and a handle. When collecting soil samples, the sampling tube needs to be manually inserted into the soil using the handle. When collecting samples from the soil surface, the sampling tube can be extracted by manually pressing. However, when collecting samples from deeper soil, multiple manual pressings are often required, which increases the labor intensity of the staff and places a heavy burden on them. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides an environmental engineering soil sampling device, which effectively solves the problem of high labor intensity for workers when sampling deep soil with existing soil sampling devices.

[0006] Furthermore, a force-bearing block is fixedly connected to the bulldozer rod, and a bulldozer groove corresponding to the force-bearing block is provided on the outer cylinder.

[0007] Furthermore, the end of the bulldozing trench away from the sampling pipe is connected to a second connecting trench that is connected to the adjusting trench.

[0008] Furthermore, a lower handle is fixedly connected to the bulldozer rod, and the outer cylinder is provided with a movable groove corresponding to the lower handle, and a lower anti-slip sleeve is provided on the lower handle.

[0009] Furthermore, an upper handle is fixed to the end of the outer cylinder away from the sampling tube, and an upper anti-slip sleeve is provided on the upper handle.

[0010] Furthermore, the sampling tube is provided with a sampling port.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In use, this utility model, through the setting of foot pedal, outer cylinder, sampling tube, upper handle, etc., makes it convenient for workers to apply force to the outer cylinder during sampling, improving the convenience of workers. In addition, through the setting of adjustment groove, first connecting groove, and connecting groove, the height of the sleeve and foot pedal can be adjusted according to the situation when collecting soil, so that the height of the foot pedal is easy for workers to step on, facilitating multiple samplings and effectively reducing the labor intensity of workers.

[0019] An environmental engineering soil sampling device, such as Figure 1-5 As shown, it includes a sampling tube 1 with a sampling port 2; an outer cylinder 6 is fixedly connected to the sampling tube 1, a bulldozer rod 16 is slidably connected to the outer cylinder 6, and a bulldozer block 17 is fixedly connected to the bulldozer rod 16 inside the sampling tube 1; an upper handle 11 is fixedly connected to the end of the outer cylinder 6 away from the sampling tube 1, and an upper anti-slip sleeve 10 is provided on the upper handle 11.

[0020] During soil collection, the sampling tube 1 is inserted into the soil through the outer cylinder 6. By applying downward force to the foot pedal 3, the foot pedal 3, through the cooperation of the lower pressure block 18 and the connecting groove 8, drives the outer cylinder 6 to move downward. The outer cylinder 6 drives the sampling tube 1 downward, so that the soil enters the sampling tube 1 through the sampling port 2. The outer cylinder 6 is then lifted upward to complete the soil collection.

[0021] Furthermore, a sleeve 4 is fitted onto the outer cylinder 6, and a foot pedal 3 is fixedly connected to the sleeve 4; an adjustment groove 12 is provided on the outer cylinder 6, and a plurality of first connecting grooves 7 connected to the adjustment groove 12 are provided on the outer cylinder 6 along the axial direction; a connecting groove 8 is connected to the first connecting groove 7, and a pressing block 18 that cooperates with the connecting groove 8 is fixedly connected to the inner wall of the sleeve 4.

[0022] By adjusting the settings of the adjusting groove 12, the first connecting groove 7, and the connecting groove 8, the height of the sleeve 4 and the foot pedal 3 can be adjusted as needed during soil collection, making the foot pedal 3 easier for workers to step on and improving the convenience of this application; specifically, as follows... Figure 1 As shown, at this time, the lower pressure block 18 is in a state of engagement with the connecting groove 8, causing the foot pedal 3 and sleeve 4 to move upward. The sleeve 4 drives the lower pressure block 18 to move into the first connecting groove 7. By rotating the sleeve 4 through the foot pedal 3, the lower pressure block 18 is rotated through the first connecting groove 7 into the adjusting groove 12. By moving the sleeve 4 and the lower pressure block 18 up and down to the corresponding position of the first connecting groove 7 through the foot pedal 3, the sleeve 4 is rotated, causing the lower pressure block 18 to rotate through the first connecting groove 7 into the connecting groove 8. By pressing down the sleeve 4 through the foot pedal 3, the lower pressure block 18 is connected to the connecting groove 8, thereby realizing the adjustment of the height of the foot pedal 3.

[0023] Furthermore, a force-bearing block 15 is fixedly connected to the bulldozer rod 16, and a bulldozer groove 14 corresponding to the force-bearing block 15 is provided on the outer cylinder 6; the end of the bulldozer groove 14 away from the sampling tube 1 is connected to a second connecting groove 13 connected to the adjusting groove 12; a lower handle 9 is fixedly connected to the bulldozer rod 16, and an movable groove corresponding to the lower handle 9 is provided on the outer cylinder 6, and a lower anti-slip sleeve 5 is provided on the lower handle 9.

[0024] After soil collection is completed, the foot pedal 3 is adjusted so that the pressure block 18 on the sleeve 4 enters the movable groove through the adjustment groove 12 and the second connecting groove 13 and contacts the force block 15. By applying a downward force to the foot pedal 3, the foot pedal 3 drives the force block 15 to move downward along the movable groove through the sleeve 4 and the pressure block 18. The force block 15 drives the bulldozer rod 16 to move downward. The bulldozer rod 16 drives the soil in the sampling tube 1 to be pushed out through the sampling port 2 through the bulldozer block 17, thus realizing the soil collection work.
