[0062] like Figure 1 , Figure 5 As shown, in an optional embodiment of the present invention, the storage box 6 has several ventilation holes 61 on its side wall.

[0063] In this embodiment, several ventilation holes 61 are provided on the side wall of the storage box 6 to balance the atmospheric pressure inside and outside the storage box 6, thereby avoiding the problem that the demolding cover 4 is difficult to open due to the inconsistent air pressure inside and outside when it descends to the lowest point.

[0064] like Figures 1-5 As shown, in an optional embodiment of the present invention, the inner diameter of the bearing ring 2 is equal to the inner diameter of the ring cutter.

[0065] In this embodiment, the inner diameter of the bearing ring 2 is equal to the inner diameter of the ring cutter to ensure that the undisturbed soil sample extruded by the demolding protrusion 41 is not obstructed by the top surface of the bearing ring 2, thereby further improving the working efficiency of the device.

[0066] The present invention provides a ring cutter demolding aid, the specific operation process of which is as follows:

[0067] The supporting base plate 1 is set up, and the storage box 6 is connected to the bottom of the supporting base plate 1. The ring cutter to be demolded is installed with its blade facing downward in the first through hole 11. Multiple ring cutters can be set up at the same time according to actual needs. The blade of the ring cutter is set in the buffer washer 21 above the bearing ring 2. The guide rail column 3 is threaded at the four corners of the upper surface of the supporting base plate 1, and the return spring 5 is respectively fitted on the outside of the guide rail column 3. Finally, the second through hole 42 is passed through the guide rail column 3 to complete the assembly of the demolding cover plate 4, wherein the demolding protrusion 41 faces downward. A downward pressure is applied to the top surface of the demolding cover plate 4, and the undisturbed soil sample in the ring cutter is squeezed out through the demolding protrusion 41, thus completing the batch processing of undisturbed soil samples from the ring cutter demolding operation.

[0068] The present invention solves the technical problem of demolding undisturbed soil samples from the ring cutter by simultaneously applying force and squeezing the corresponding ring cutter soil sample with several demolding protrusions 41.

[0069] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
