[0048] The cross beam 804 is fixedly connected with an elongation rod 701 of the elongation mechanism 7. The elongation rod 701 is vertically arranged and is of a hollow structure. It is slidably connected with a lower ramming rod 605 through a hydraulic telescopic rod 604. The hydraulic telescopic rod 604 is driven by the hydraulic pump 603.

[0051] When the utility model is actually used: When constructing with the quick backfilling device for the probing hole, the operator uses the operation handle control mechanism 9 to drive the gear 202 to rotate, driving the crawler 201 to move, so that the device moves forward and backward. Place the material discharging port of the device above the probing hole, connect the filling material supply system in the material discharging box 501 to the device and turn on the power supply. Then, turn on the switch of the automatic material discharging mechanism 5 on the handle control mechanism 9. Then, through the automatic material discharging mechanism 5 and the aggregate mechanism 4, the sand and gravel fall to the bottom of the material discharging funnel 401 through the horizontal transportation unit, and the filled sand and gravel material slides into the probing hole along the bottom pipeline to complete the quick backfilling. When backfilled to a certain height, turn on the switch of the motor 705 of the elongation mechanism 7 to adjust the telescopic length. The worm rotates to drive the screw rod 702 to rotate. Since the screw rod 702 is axially limited to the tamping head 601 slidingly connected below it, the tamping head 601 can be driven to rotate. During the rotation process, due to the threaded connection with the tamping rod, the up and down displacement of the tamping head 601 can be realized, so that the tamping head 601 can hammer the backfilling material in the backfilled probing hole. The screw rod 702 is designed with an external thread, and components can be added to the top of the screw rod 702 during later improvement; turn on the switch of the hydraulic hammering and tamping mechanism 6, and the hydraulic pump 603 drives the hydraulic telescopic rod 604 to work, so that the tamping rod 605 drives the tamping head 601 threadedly connected to it to perform up and down hammering and tamping. As the bottom backfilling material is tamped and compacted to fill the hole, the material squeezes the hydraulic hammering and tamping mechanism 6 and the elongation mechanism 7 upward, and the elongation rod 701 and the fixedly connected rising rod 802 rise and break through the upward limit of the ratchet wheel. The ratchet wheel 801 of the rising rod 802 will automatically move upward along the rack 106 until the probing hole is backfilled. Move the device to another probing hole, turn on the switch of the locking mechanism of the ratchet wheel 801, and manually disengage the pawl 805 from the ratchet wheel 801, and the rising rod 802 and the elongation rod 701 can be released to fall.
