[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0021] The present application discloses a portable electric compactor. Figure 1 and Figure 2 The present invention comprises a housing 1, with a sampling tube 2 for holding a soil sample mounted on top of the housing 1. A mounting bracket 3 is detachably connected to one side of the sampling tube 2 at the top of the housing 1. A mounting plate 4 is detachably connected to the mounting bracket 3 above the sampling tube 2. A compacting hammer 5 for compacting the soil sample in the sampling tube 2 is vertically slidably mounted on the mounting plate 4. A first driving member 6 for driving the compacting hammer 5 is mounted on the mounting plate 4. A storage slot 11 for storing the mounting bracket 3 and the mounting plate 4 is provided on one side of the housing 1, and a mounting door 7 is mounted at the opening of the storage slot 11.

[0022] In the embodiment of the present application, the first driving member 6 can be used to drive the compacting hammer 5 to move vertically back and forth to compact the soil sample in the sampling tube 2. After the test is completed, the mounting plate 4 and the mounting frame 3 can be removed and placed in the storage slot 11. Then, the mounting door 7 can be locked and the electric compactor can be packed for the staff to carry. In order to facilitate the staff to grab the box 1, a handle 40 is also welded to one side of the box 1. In this way, some parts of the electric compactor of the present application can be detachably stored in the box 1, and the staff can carry the box 1 with them, which is convenient to operate and improves the test efficiency.

[0023] Specifically, the first driving member 6 comprises an electric push rod 61, which is vertically bolted to the mounting plate 4 and faces the sampling tube 2 below. A compacting hammer 5 is bolted to the movable end of the electric push rod 61. The electric push rod 61 drives the compacting hammer 5 to move back and forth vertically to compact the soil sample within the sampling tube 2. After the test is completed, the bolts on the electric push rod 61 and the compacting hammer 5 are removed, and the electric push rod 61 and the compacting hammer 5 can be placed into the storage tank 11.

[0024] Reference Figure 3 and Figure 4 A connector 8 is installed between the mounting frame 3 and the mounting plate 4. The connector 8 includes a latch 81. The mounting plate 4 is mounted horizontally on the top of the mounting frame 3. A first positioning hole 31 having a size matching that of the latch 81 is vertically defined on the top of the mounting frame 3. The mounting plate 4 has a through hole 41 in communication with the first positioning hole 31. The latch 81 is vertically inserted into the through hole 41 and the first positioning hole 31. The portion of the latch 81 located within the first positioning hole 31 has a groove 811 defined on the outer wall. A guide hole 32 in communication with the first positioning hole 31 is horizontally defined on one side of the mounting frame 3. A slide post 82 is slidably connected to the guide hole 32 for inserting into the groove 811. A second driving member is mounted on the mounting frame 3 for driving the slide post 82 to slide closer to the groove 811.

[0025] In this embodiment, mounting bracket 3 is vertically mounted on top of housing 1. Mounting plate 4 is then placed horizontally on top of mounting bracket 3. Pin 81 is vertically inserted into through-hole 41 and first positioning hole 31. A second actuator then drives slide post 82 to slide into groove 811 of pin 81. Once the test is complete, slide post 82 is driven out of groove 811 by the second actuator, and mounting plate 4 can be removed by pulling out pin 81. This ensures a secure connection between mounting plate 4 and mounting bracket 3 while facilitating quick and efficient installation and removal.

[0026] Specifically, the second driving member includes a spring 9, and the slide post 82 includes a push block 821 whose outer diameter matches the groove 811, and a slide rod 822 whose outer diameter matches the guide hole 32. A first mounting groove 33 with an inner diameter matching the push block 821 is defined on the inner wall of the first positioning hole 31 along the depth direction of the guide hole 32. The spring 9 is sleeved on the slide rod 822 and located within the first mounting groove 33. The ends of the spring 9 abut against the push block 821 and the inner bottom wall of the first mounting groove 33, respectively.

[0027] In the embodiment of the present application, a worker manually pulls out the slide bar 822 to insert the latch 81 into the first positioning hole 31 and the through hole 41. Subsequently, the slide bar 822 is released, and the spring 9, through its elastic force, drives the push block 821 to slide and insert into the groove 811 of the latch 81. This prevents the latch 81 from vibrating and falling out of the first positioning hole 31 and the through hole 41 when the hammer 5 compacts the soil sample in the sampling tube 2.

[0028] Specifically, a sampling slot 12 having a size adapted to the outer diameter of the sampling tube 2 is provided on the top of the housing 1, and the sampling tube 2 is inserted into the sampling slot 12. A positioning member for limiting the sampling tube 2 from vertically sliding out of the sampling slot 12 is installed on the top of the housing 1, and the positioning member includes at least two baffles 10 and a plurality of first positioning bolts 102. The two baffles 10 are arranged on both sides of the sampling slot 12 in a radially symmetrical sliding manner along the sampling slot 12. The baffles 10 are provided with at least two parallel strip holes 101 along their own sliding direction. A plurality of first threaded holes corresponding one to one with the strip holes 101 are provided on the top of the housing 1. The first positioning bolts 102 correspond one to one and are threadedly connected to the first threaded holes after passing through the strip holes 101.

[0029] In this embodiment, the sampling cartridge 2 is positioned and inserted into the sampling slot 12. The baffles 10 on both sides are slid together to abut the outer wall of the sampling cartridge 2. The baffles 10 are then secured to the top of the housing 1 using the first positioning bolts 102. This allows the sampling cartridge 2 to be removed and placed in the storage slot 11 after use. The baffles 10 on both sides abutting the outer wall of the sampling cartridge 2 improve the stability of the sampling cartridge 2 within the sampling slot 12.

[0030] Furthermore, a second mounting slot 13 for inserting the mounting bracket 3 is provided on one side of the sampling tube 2 at the top of the housing 1. A stopper 20 is installed on the housing 1 to prevent the mounting bracket 3 from sliding out of the second mounting slot 13. The stopper 20 includes a second positioning bolt 201. A second positioning hole 14 communicating with the second mounting slot 13 is provided horizontally on the side wall of the housing 1. The mounting bracket 3 is provided with a second threaded hole 34 communicating with the second positioning hole 14. The second positioning bolt 201 passes through the second positioning hole 14 and is threadedly connected to the second threaded hole 34. The mounting bracket 3 is fixed to the housing 1 by the second positioning bolt 201, which not only ensures the stability of the mounting bracket 3 on the housing 1 but also allows the mounting bracket 3 to be removed and placed in the storage slot 11.

[0031] Furthermore, a support member for connecting to the box body 1 is mounted on the end of the mounting plate 4 away from the mounting bracket 3. The support member includes a telescopic rod 30, one end of which is rotatably connected to the end of the mounting plate 4 away from the mounting bracket 3. A retaining groove 15 is vertically formed on the top of the box body 1 to accommodate the other end of the telescopic rod 30.

[0032] In the embodiment of the present application, after the mounting plate 4 is installed on the top of the mounting frame 3 through the connecting member 8, the telescopic rod 30 is rotated and aligned with the limiting groove 15 below. The telescopic rod 30 is then extended and inserted into the limiting groove 15, and can cooperate with the mounting frame 3 to support the mounting plate 4, thereby further improving the stability of the mounting plate 4 on the box body 1.

[0033] Specifically, the telescopic rod 30 comprises a mounting tube 301 and a screw 302. One end of the screw 302 is pivotally mounted on the end of the mounting plate 4 away from the mounting bracket 3 via a rotating shaft. The mounting tube 301 is threadedly connected to the outer wall of the screw 302. The inner diameter of the retaining groove 15 is the same as the outer diameter of the mounting tube 301. When the telescopic rod 300 is rotated to directly above the retaining groove 15, a worker manually rotates the mounting tube 301, causing it to slide vertically into the retaining groove 15.

[0034] The implementation principle of a portable electric compactor in the embodiment of the present application is as follows: the compacting hammer 5 can be driven to move vertically back and forth by the first driving member 6 to compact the soil sample in the sampling tube 2. After the test is completed, the mounting plate 4 and the mounting frame 3 can be removed and placed in the storage slot 11. Then, the mounting door 7 can be locked to pack the electric compactor for the staff to carry. A handle 40 is also welded to one side of the box body 1. In this way, some parts of the electric compactor of the present application can be detachably stored inside the box body 1, and the staff can carry the box body 1 with them, which is convenient to operate and improves the test efficiency.
