The lifting drive unit 3 is connected to the top of the grab frame 4 through a steel wire rope, and a hydraulic unit for rotating the two bucket petals 5 is provided inside the grab frame 4.

[0026] Specific implementation: During the movement, the sliding block 607 will drive the rectangular plate 801 to squeeze the airbag 802, and transport the internal gas of the airbag 802 to the inner cavity opened inside the rectangular seat 704 through the air pipe 803, and then transport it to the rectangular cavity opened inside the third cone block 705 through the through hole, thereby increasing the gas-liquid pressure on one side of the rectangular piston, so that the rectangular piston drives the fourth cone block to move toward the outside of the third cone block 705. With the cooperation force of the fourth cone block, the squeezing state between the third cone block 705 and the roller 706 is improved, so as to assist in increasing the crushing pressure of the crushing block 710 on the soil block during the closing process of the two bucket petals 5, thereby further improving the use effect of the device, wherein a sensor and an air supply pipe are arranged inside the airbag 802.

[0027] Working principle: When in use, the crawler-type mobile vehicle 1 is first used to move the entire device to a suitable position outside to be taken soil. After that, the lifting drive unit 3 is used through the steel wire rope and cooperates with the gravity of the grab frame 4 and the bucket petals 5 to make the grab frame 4 and the bucket petals 5 enter the interior of the soil layer to be taken in a vertical state. After that, the hydraulic unit inside the grab frame 4 will drive the bucket petals 5 to rotate and close to store the taken soil between the two bucket petals 5. Then, the hanger 2, the lifting drive unit 3, the grab frame 4 and the bucket petals 5 are rotated to transport the taken soil to a suitable position outside. The driving parts, power transmission system and operating system involved are publicly known technical fields to those skilled in the art, so they are not described in detail in this application. When the two bucket lobes 5 rotate relative to each other to remove the soil inside the soil layer, the bucket lobes 5 will drive the second rectangular frame 602, the rotating shaft 605 and the second gear 604 to rotate around the hinge shaft 9 through the first rectangular frame 601. During this process, under the action of the first gear 603, the second gear 604 will drive the rotating shaft 605 and the first synchronous belt 701 to rotate. The linkage effect between the first synchronous belt 701, the synchronous transmission belt and the second synchronous belt 702 is used to transmit power to the second synchronous belt 702, so that the second synchronous belt 702 drives the reciprocating screw 703 to rotate. Then, the linkage effect between the reciprocating screw 703 and the screw seat is used to transmit power to the screw seat, so that the screw seat drives the multiple third cone blocks 705 to move toward the roller 706 through the rectangular seat 704, so that the roller 706 drives the fixed rod 707 and the crushing block 710 to move toward the outside of the first rectangular frame 601, so as to pre-crush the large soil blocks between the two bucket lobes 5. At the same time, the second gear 604 will drive the sliding block 607, the limiting slider 608 and the first cone block 609 to move in the direction of the second cone block 610 through the rack 606. When the two bucket petals 5 are about to complete the closing work, the rectangular seat 704 and the third cone block 705 will be reset to allow the crushing block 710 to enter the first rectangular frame 601 to prevent the closing effect between the two bucket petals 5 from being affected. During this process, the second gear 604 will continue to drive the rack 606 to move slightly. At this time, the first cone block 609 will squeeze the second cone block 610, so that the second cone block 610 drives the sliding plate 613 and the wear-resistant sealing gasket to move relative to each other through the connecting block 612, so as to automatically ensure the sealing and closing state between the two bucket petals 5. During the movement, the sliding block 607 will drive the rectangular plate 801 to squeeze the airbag 802, and transport the internal gas of the airbag 802 to the inner cavity opened inside the rectangular seat 704 through the air pipe 803, and then transport it to the rectangular cavity opened inside the third cone block 705 through the through hole, thereby increasing the gas-liquid pressure on one side of the rectangular piston, so that the rectangular piston drives the fourth cone block to move toward the outside of the third cone block 705. With the cooperation force of the fourth cone block, the squeezing state between the third cone block 705 and the roller 706 is improved, so as to assist in increasing the crushing pressure of the crushing block 710 on the soil block during the closing process of the two bucket petals 5.
