As shown in fig. 1 and 3, the isolation frame 6 includes an isolation sheet 601 mounted on a surface of the separation block 4, a sealing division bar 602 is mounted on a surface of the isolation sheet 601 away from the separation block 4, and a support stop 603 for supporting the pneumatic push rod 5 is mounted on a side surface of the sealing division bar 602.
The isolation frame 6 is arranged to cooperate with the two accommodating holes 301 to work, because the cross section of the pneumatic push rod 5 is of an L-shaped structure, when the sealing parting strip 602 divides the upper part of the partition block 4 into two regions, the more the injected gas is, the higher the pressure is, and then the pneumatic push rod 5 can realize the purpose of downward sliding (at this time, the pulling spring 501 can be stretched), and because the side surface of one end of the pneumatic push rod 5, which is far away from the inclined push rod 7, is provided with the pulling spring 501, and one end of the pulling spring 501, which is far away from the pneumatic push rod 5, is connected with the inner wall of the end part of the hollow cavity 302, the pulling spring 501 can play a role after the pressure is reduced, the pneumatic push rod 5 is pulled to ascend, and after the pulling spring 501 is reset, the inclined block 8 can be vertical, so that the soil sample in the survey main sleeve.
As shown in fig. 1 and 4, the one end side wall of the main survey sleeve 3 close to the fixed mount 1 is connected with a position-clamping column 303 for limiting the position of the pneumatic push rod 5 through a thread, the one end side wall of the main survey sleeve 3 far from the fixed mount 1 is sleeved with a spiral strip 304, the surface of the spiral strip 304 is provided with a fixed plate 305, and the fixed plate 305 is provided with a plurality of sweeping columns 306 with linearly increasing heights.
In order to avoid the slope piece 8 can sweep into survey main cover 3 big granule's stone thereby plug up accommodation hole 301, so realize through helical strip 304, during its concrete operation, in case survey main cover 3 and bore underground, then helical strip 304 can stir out soil and make the dynamics of driling into of surveying main cover 3 stronger, change into the soil layer, simultaneously when helical strip 304 with periodic motion, the accessible is swept post 306 and is pushed away or smash the stone of surveying big granule around the main cover 3, avoid the stone to block the condition emergence of cavity 302.
As shown in fig. 1, 2 and 3, the cross section of the hollow cavity 302 is of a quadrilateral structure, and the one end of the hollow cavity 302 far away from the fixing frame 1 is provided with a separation mechanism 10 separating two accommodating holes 301, the separation mechanism 10 comprises a cross section frustum-shaped structure and an auxiliary drill cover 1001 connected with the other end of the survey main sleeve 3, an auxiliary spiral strip 1002 is sleeved on the side wall of the auxiliary drill cover 1001, a separation sheet 1003 is connected to the central position in the auxiliary drill cover 1001, and a push-out sheet 1004 connected with the surface of the separation block 4 and used for pushing out the soil sample stored in the hollow cavity 302 is installed at one end of the separation sheet 1003 far away from the auxiliary drill cover 1001.
The hollow cavity 302 can isolate the two receiving holes 301, so that the soil entering from the two receiving holes 301 cannot mix (if a soil sample of the same soil layer is collected, the isolating mechanism 10 may not be unfolded, and the unfolded isolating mechanism 10 is taken as an example for explanation), the soil is immediately blocked by the blocking piece 1003 after entering the hollow cavity 302 along the inclined block 8, so that the soil cannot mix easily, and then the soil enters the auxiliary drill cover 1001 (the side wall of the auxiliary drill cover 1001 is sleeved with the auxiliary spiral strip 1002, which has the same function as the spiral strip 304), and after the survey main sleeve 3 is taken out, the blocking piece can pull out the soil with the push-out piece 1004 by pulling the auxiliary drill cover 1001, so that the situation that the soil is blocked in the survey main sleeve 3 cannot occur.
The blocking sheet 1003 comprises a fixed card 1005 and a connecting column 1006, the end portions of the fixed card 1005 and the connecting column 1006 are mounted on the surface of the push-out sheet 1004, a sliding clamping groove 1007 is formed in the fixed card 1005, movable cards 1008 are connected to the surfaces of the two sides of the fixed card 1005, the connecting column 1006 is connected with the two end side walls, close to the fixed card 1005, of the movable cards 1008 respectively, and the connecting column 1006 is located in the sliding clamping groove 1007.
