The driven unit gear set stereographic map of drilling rod dish of the present invention and stopple coupon dish as shown in Figure 9, corer dish rotating shaft 13, drilling rod dish rotating shaft 6, drilling rod disk drive shaft 19 and each freedom of corer disk drive shaft 20 a pair independently bearing arrangement are fixed on and change on bar gear case, changing bar gear case is fixed on gear box support 14, and gear box support 14 is connected with the housing of sampling thief.Drilling rod disk drive shaft 19 is enclosed within corer disk drive shaft 20, and both with one heart and do not contact.Drilling rod dish rotating shaft 6 is enclosed within corer dish rotating shaft 13, and both also with one heart and do not contact.Therefore four axles can freely rotate mutually without interfering with each other.Drilling rod disk drive shaft 19 is connected with drilling rod dish rotating shaft 6 by drilling rod dish drive gear set 22, drives drilling rod dish rotating shaft 6 to rotate.Corer disk drive shaft 20 is connected with corer dish rotating shaft 13 by corer dish drive gear set 21, drives corer dish rotating shaft 13 to rotate.By said structure, the rotation of drilling rod dish 3 and corer dish 7 can be relatively independent, do not interfere with each other.
Drilling rod dish of the present invention and corer dish driven unit joint stereographic map, comprise spring 17, crossover sub 18, drilling rod motion driving shaft 16 as shown in Figure 10.
Drilling rod dish drive sub stereographic map of the present invention as shown in figure 11, after the top yi word pattern joint of drilling rod motion driving shaft 16 docks with drilling rod rotary disk driving shaft 19 bottom, drilling rod motion driving shaft 16 rotates can be with drilling rod rotary disk driving shaft 19 to rotate.Have two blocks at the bottom outlet inner ring of drilling rod rotary disk driving shaft 19, these two stop location are symmetrical also can be coordinated with drilling rod motion driving shaft 16 yi word pattern joint, is also symmetrical at circumferential position, and therefore no matter yi word pattern joint rotates forward reversion can coordinate with block.The tip designs of yi word pattern joint is fillet, and the bottom of block is also designed to fillet.When yi word pattern joint docks with drilling rod rotary disk driving shaft 19, drilling rod rotary disk driving shaft 19 is static, and drilling rod motion driving shaft 16 rotates and rises.When yi word pattern joint docks with drilling rod rotary disk driving shaft 19, if yi word pattern joint does not have overlapping with the xsect of block, then yi word pattern joint directly enters the bottom outlet of drilling rod rotary disk driving shaft 19, drilling rod motion driving shaft 16 rotate≤scope of 120 ° in, yi word pattern joint will be blocked by block, drilling rod motion driving shaft 16 drives drilling rod rotary disk driving shaft 19 jointly to rotate, and is realized the rotation of drilling rod dish 3 by gear set transmission.If yi word pattern joint has overlapping with the xsect of block, due to the rotation that fillet and the drilling rod motion driving shaft 16 of yi word pattern joint and block contact site continue, yi word pattern joint can not block and make drilling rod motion driving shaft 16 increase by block, yi word pattern joint can slide in the bottom outlet of drilling rod rotary disk driving shaft 19 gradually along with rotation is risen, and continues rotary actuation drilling rod rotary disk driving shaft 19.And, when drilling rod motion driving shaft 16 prepares stacks rotary disk driving shaft 19, the locking of drilling rod dish 3 is removed, can rotate freely, the now rotation of drilling rod dish 3 reduces resistance during docking, can ensure no matter yi word pattern joint fillet is that relative direction or equidirectional contact with the fillet of block, can slip over smoothly, make yi word pattern joint enter bottom outlet.
Institute of the present invention corer dish drive sub stereographic map as shown in figure 12, the principle that drilling rod motion driving shaft 16 drives corer disk drive shaft 20 to rotate is similar to driving the principle of drilling rod disk drive shaft 19, and difference is the docking being changed into three joints by the docking of above-mentioned two joints.Drilling rod motion driving shaft 16 penetrates crossover sub 18 endoporus and drives crossover sub 18 to rotate, and crossover sub 18 enters in corer disk drive shaft 20 bottom outlet and drives corer disk drive shaft 20 to rotate.Crossover sub 18 can move axially within the specific limits along the drilling rod driving shaft 16 that moves, transition connects 18 when being installed on drilling rod motion driving shaft, spring 17 bottom and drilling rod motion driving shaft 16 are fixed, top and crossover sub 18 bottom surface are fixed, spring 17 is in compressive state, the bottom surface of crossover sub 18 endoporus is spacing by the block of drilling rod motion driving shaft 16, and crossover sub 18 can not be deviate from, and crossover sub 18 relatively drilling rod motion driving shaft 16 is in the extreme higher position in range of movement.The block of now drilling rod motion driving shaft 16 can contact cooperation with the block of crossover sub 18 endoporus when both relatively rotate, and makes drilling rod motion driving shaft 16 that crossover sub 18 can be driven to rotate, thus can drive corer disk drive shaft 20 and rotate.When crossover sub 18 is by downward pressure, crossover sub 18 overcomes spring 17 elastic force and moves downward, the block of now drilling rod motion driving shaft 16 can not contact when both relatively rotate with the block of crossover sub 18 endoporus, and namely the rotation of drilling rod motion driving shaft 16 can not drive the rotation of crossover sub 18.By controlling the position of crossover sub 18, can reach the object driving drilling rod dish 3 and corer dish 7 respectively, both guarantees do not have the interference in motion.As previously mentioned, the rotation of drilling rod dish 3 and the rotation of corer dish 7 also need drilling rod electric rotating machine and drilling rod translation motor to drive, perform when driving and need the upwards translation of leading screw rotary actuation gear case entirety, drive drilling rod motion driving shaft 16 upwards translation realizes the docking of joint, thus transmitting torque.When only needing rotary coring pipe dish 7, the upwards translation of leading screw rotary actuation gear case.Now drilling rod motion driving shaft 16 drives corer disk drive shaft 20 to rotate by crossover sub 18, but the yi word pattern joint of drilling rod motion driving shaft 16 does not also insert in the bottom outlet of drilling rod disk drive shaft 19 when this position, so drilling rod disk drive shaft 19 can not be driven to rotate.When only needing rotary drill rod dish 3, the upwards translation of leading screw rotary actuation gear case.Because corer disk drive shaft 20 is axially fixing, therefore, along with gear case moves upward, the end face of corer disk drive shaft 20 bottom outlet is pressed in the end face of crossover sub 18, overcome spring 17 elastic force by crossover sub 18 to pressing down, until the yi word pattern joint of drilling rod motion driving shaft 16 enters in the bottom outlet of drilling rod disk drive shaft 19, drilling rod disk drive shaft 19 can be driven to rotate.Now in the axial direction, the block of drilling rod motion driving shaft 16 is positioned at the top of crossover sub 18 endoporus block, both each other arbitrarily rotation also can not contact transmitting torque, drilling rod disk drive shaft 19 can only be driven when therefore drilling rod motion driving shaft 16 rotates, corer disk drive shaft 20 can not be driven.In sum, the setting of crossover sub 18, makes the rotation that drilling rod dish 3 and corer dish 7 can be separate, does not interfere with each other.
Therefore the present invention have can realize the sampling of multicore many bar, can multiple repairing weld and sampling quantity large, change bar change core accurately flexibly, only can reclaim the advantage that the sample gathered reduces return capsule weight.
Above-described embodiment, the just one of the present invention's more preferably embodiment, the usual change that those skilled in the art carries out within the scope of technical solution of the present invention and replacing all should be included in protection scope of the present invention.
