[0021] The operation method and working principle of the geology surveying rock-soil sampling device are as follows:
[0022] 1. Pre-adjustment of the sampling device.
[0023] As Figure 1 shown, the pulley hook 12 hooks the first fixing ring 2, the motor device is started to drive the rope wheel 10 to release the rope, with the release of the traction rope 3, the sliding sleeve 13 moves downward along the sampling cylinder 4, thereby adjusting the pedal 1 to a lower height for easy pedaling; after the motor device stops running, the rope wheel 10 is locked by the self-locking function, at this time, both ends of the traction rope 3 are in a fixed state, so that the sliding sleeve 13 cannot move downward along the sampling cylinder 4.
[0024] 2. Sampling operation.
[0025] As shown in Figure 1 , Figure 3 , Figure 5 , the tip of the sampling cylinder 4 is placed on the sampling point, the hand-held handle 8 keeps the sampling cylinder 4 vertical, and the foot pedals 1 drive the sampling cylinder 4 to insert into the rock soil; when the lower side of the pedal 1 contacts with the ground, the motor device is started to drive the rope wheel 10 to reel the rope, and with the recovery of the traction rope 3, the pulley hook 12 will drive the sliding sleeve 13 to move upward along the sampling cylinder 4, so that the pedal 1 is adjusted to the height convenient for stepping again, and the sampling cylinder 4 is continuously driven downward by stepping the pedal 1; the sampling cylinder 4 is gradually driven downward by the above-mentioned method until the required sampling depth is reached; during the above-mentioned operation process, the piston 17 cannot move downward due to the contact with the rock soil inside the sampling cylinder 4, so that the height of the handle 8 is constant and always convenient for hand-holding; since the height of the pedal 1 is adjustable, the body weight of the sampling personnel can be fully utilized to drive the sampling cylinder 4 to move downward, and the depth range of the rock soil sampling is significantly improved.
[0026] 3. Sample removal.
[0027] As shown in Figure 3 , Figure 5 , after the sampling cylinder 4 is taken out of the rock soil, if the sampling is shallow, the push rod 7 can be manually driven to move, and the piston 17 is used to drive the sample to move out of the tip of the sampling cylinder 4; if the sampling is deep, it is difficult for the human to drive the push rod 7 to move, at this time, the pulley hook 12 can be taken off from the first fixed ring 2, hooked to the second fixed ring 9, and the motor device is started to drive the rope wheel 10 to reel the rope, and with the recovery of the traction rope 3, the pulley hook 12 will drive the push rod 7 and the piston 17 to move in the direction of the tip of the sampling cylinder 4, and drive the sample to move out of the sampling cylinder 4.
[0028] In the embodiment, the motor device is used to provide driving and locking functions for the rope wheel 10, and needs to have functions of forward rotation, reverse rotation and parking self-locking, and motor products with the above-mentioned functions are common in the prior art, which can be flexibly selected according to actual needs; based on the above-mentioned use of the motor device, and the traction rope 3 and the pulley hook 12 work in the mode of a force-saving pulley, the output power requirement of the motor device of the utility model is relatively low, and a small power motor type can meet the power requirement; in actual use, the motor device does not need to run for a long time, and the power consumption is relatively small, so a small capacity power supply can meet the actual needs; based on the above, when the utility model is implemented, a small motor device and a power supply can be selected to ensure that the local geological survey rock soil sampling device has good portability and flexibility.
[0029] In the embodiment, the sampling cylinder 4 and the push rod 7 are made of metal material to ensure strength and durability; the traction rope 3 should have high strength, and can be selected from high-strength rope products such as steel wire rope, synthetic fiber rope, aramid fiber rope, ultra-high molecular weight polyethylene rope and composite material rope; the pulley hook 12 is a commonly used lifting accessory in the prior art, which is usually composed of one or more pulleys and a hook body, and can be selected according to the specific size of the traction rope 3, the first fixed ring 2 and the second fixed ring 9.
[0030] As shown in Figure 1 , Figure 2 , in the embodiment, the upper end of the sampling cylinder 4 is sleeved with a sleeve 5, and the rope wheel 10 and the rotating head 6 are rotationally fixed to the side of the sleeve 5, so as to improve the easy implementation of the utility model; further, the sleeve 5 has a top 16 at the upper end, the top 16 is located above the sampling cylinder 4, the top 16 is provided with a central hole 15, and the push rod 7 passes through the central hole 15 and is in sliding fit with the central hole 15, so that the sleeve 5, the sampling cylinder 4 and the push rod 7 are easy to assemble and have high cooperation stability.
