In the above embodiment, before sampling, the components are assembled, first, the electric push rod 8 is screwed into the fixed plate 3, and the bottom of the electric push rod 8 is hinged to the T-shaped connecting block 94 on the telescopic leg 9, then the sliding inner rod 92 is pulled out from the rotary outer rod 91, and the sliding inner rod 92 is limited by the limiting bolt, at this time, the electric push rod 8 is started, the electric push rod 8 is extended to drive the telescopic leg 9 to rotate integrally at the bottom of the fixed plate 3, so that the roller connected to the sliding inner rod 92 of the telescopic leg 9 is supported on the ground, so as to keep the outer ring 1 stable, then the engine 4 and the drill rod 10 are inserted into the inner ring 2 from above the inner ring 2 until the engine 4 presses the top surface of the bottom ring 5, at this time, the upper press plate 73 is rotated to rotate the upper press the engine 4, and the upper press plate 73 corresponds to the notch 41 on the top surface of the engine 4, then the upper press plate 73 is manually, the rotary rod 63 is rotated by the rotary rod 63, when the rotary ring 61 is rotated, the outer gear 62 rotates to drive the rotary screw 71, and the buffer screw 74 rotates to observe the deformation of the telescopic screw 74, and the telescopic screw 71 located above the telescopic screw 72, at this time, the telescopic screw 71 is rotated, and the telescopic spring 71 is positioned above the telescopic spring 71, and the telescopic spring 71 is pressed.
When sampling begins, the engine 4 is started, the engine 4 drives the drill rod 10 to work, when the drill rod 10 begins to drill downwards into the ground, the electric push rod 8 is started to contract, the electric push rod 8 contracts to drive the telescopic supporting legs 9 to rotate, the telescopic supporting legs 9 expand outwards, the supporting outer ring 1, the mounting inner ring 2 and the engine 4 are adjusted to move downwards, and the drill rod 10 is matched to work.
Further, since the engine 4 is usually accompanied by a large shake during the drilling process, the gear transmission mode of the present invention can drive the rotation of the upper compressing member 7 by means of the rotating rod 63, which makes it easier to fasten and dismount, but when the engine shakes a lot, the engine is undesirably rotated, although the buffer spring 74 can prevent the rotation to some extent, the best effect cannot be achieved, and if the engine falls off, a serious safety accident may be caused.
To this end, as shown in fig. 10, in the preferred embodiment of the present invention, each of the notches 41 is provided with a symmetry axis 42 passing through the center of a circular arc, an extension line of the symmetry axis 42 of at least one notch 41 does not pass through the center 44 of the top surface of the engine 4, and an extension line of the symmetry axis 42 of at least one notch 41 passes through the center 44, and as exemplified in fig. 10, extension lines of the symmetry axes 42 of two notches 41 do not pass through the center 44.
Thus, the forces during rotation are mainly concentrated on one or two of the notches 41 and do not act on three notches 41 simultaneously, or it can be understood that the forces acting on the non-eccentric notches 41 are smaller with respect to the forces of the eccentric notches 41, so that the engine is not simultaneously forced off uniformly. And the second included angle 43 of the extension lines of the symmetry axes 42 of the two notches 41 which do not pass through the circle center 44 is less than 120 degrees, and the two notches 41 are far away from each other, so that the acting force is concentrated on the notch 41 with the increased eccentricity, and the effect of preventing the engine from being separated is further improved.
In order to reduce the acting force of the eccentric notch 41, the intersection point 45 is defined between the symmetry axis 42 of the notch 41 and the top circle of the engine, the first included angle between the intersection point of two adjacent notches 41 and the circle center 44 is 120 degrees, the included angle between the connecting line from the intersection point 45 to the circle center 44 and the symmetry axis 42 is a third included angle 47, the larger the third included angle 47 is, the stronger the elastic force of the buffer spring 74 on the upper pressure plate 73 corresponding to the third included angle is, so that the buffer spring 74 with stronger elastic force is matched to reduce the rotating force, and the separation of the engine 4 caused by rotation is avoided.
In addition, in order to further buffer the corresponding rotating force in one or two eccentric slots 41, the present invention further provides that the upper pressure plate 73 and the telescopic screw 72 can rotate mutually at a rotation angle smaller than 15 degrees, the rotation angle is set so that the rotating force can be buffered, the rotation between the upper pressure plate 73 and the telescopic screw 72 is not greatly influenced, the insertion of the telescopic screw 72 onto the rotating screw 71 is not influenced, and the rotation angle is preferably 4 degrees or more and 10 degrees or less, so as to balance the reduction of the rotation and the easy insertion.
To sum up, in the preferred embodiment of the present invention, the extension line of the symmetry axis 42 of at least one notch 41 does not pass through the center 44 of the top surface of the engine, and the extension line of the symmetry axis 42 of at least one notch 41 passes through the center 44, so that the pressure on the notch 41 during the operation of the engine and during abnormal shaking does not concentrate uniformly on the top of the engine, and the intersection angle between the extension lines of the two symmetry axes 42 that do not pass through the center 44 is less than 120 degrees, which is optimal when the angle is less than 110 degrees, so that the acting force acting on the top surface can be reduced to a certain extent, thereby preventing the shaking of the engine during the operation of the engine from causing looseness, and simultaneously, the upper pressure plate and the expansion screw can rotate with each other at a rotation angle less than 15 degrees, the optimal rotation angle is more than 4 degrees and less than 10 degrees, so that the unexpected rotation force is mainly concentrated on one or two upper pressure plates during the rotation, thereby preventing the simultaneous action on the three upper pressure plates from causing the simultaneous looseness of the engine to cause the shaking of the engine and even falling off, further, and further, the action of the buffer spring 74 is matched, so that the rotation force is transmitted to the spring buffer, and the spring is further, for better buffer, thereby preventing the elastic force from increasing more.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
