Detailed Description
The present invention is further illustrated by the following specific examples, which are intended to be illustrative, not limiting and are not intended to limit the scope of the invention.
The utility model provides a prevent sample drill bit mechanism that runs off technique side with plastic function of fetching earth, as shown in fig. 1-4, provide a prevent sample drill bit mechanism that runs off with plastic function of fetching earth, including drilling rod 1, the inner chamber bottom of drilling rod 1 is provided with drilling rod circular fixture block 2, the top of drilling rod circular fixture block 2 is run through and has been seted up half fan-shaped groove 3, the inner chamber of drilling rod 1 is provided with screw thread thief rod 4, the inner chamber bottom of screw thread thief rod 4 is provided with first circular fixture block 5, the top of first circular fixture block 5 is run through and has been seted up first fan-shaped groove 6, the inner chamber of screw thread thief rod 4 is provided with round bar 7, the circular fixture block 8 of second has been cup jointed to the bottom of round bar 7, the top of the circular fixture block 8 of second is run through and has been seted up second fan-shaped groove 9, the top of screw thread thief rod 4 is provided with hand (hold) 10.
Wherein, the bottom of drilling rod 1 is provided with drill bit 11, and drill bit 11 is hollow.
In this embodiment, the drill bit 11 is hollow so that the drill bit 11 is installed at the bottom of the drill rod 1, and the soil enters the soil through the drill bit 11 and the drill rod 1, and the soil enters the interior of the threaded sampling rod 4 through the half-sector-shaped groove 3 on the drill rod circular fixture block 2 at the bottom of the drill rod 1 and the first sector-shaped groove 6 on the first circular fixture block 5 at the bottom of the threaded sampling rod 4, so as to perform geological survey on the soil in the threaded sampling rod 4.
Wherein, the drill rod 1 and the thread sampling rod 4 are both hollow.
In this embodiment, set up drilling rod 1 and screw thread thief rod 4 into the cavity form, screw thread thief rod 4 passes through the screw thread and installs the inner chamber at drilling rod 1, again through drill bit 11 drive drilling rod 1 and screw thread thief rod 4 enter into soil in, soil enters into the inner chamber of screw thread thief rod 4 and surveys the geology through soil.
Wherein, the thread sampling rod 4 is installed in the inner cavity of the drill rod 1 through threaded connection.
In this embodiment, because screw thread thief rod 4 need install the inner chamber at drilling rod 1, conveniently take out or install screw thread thief rod 4 from the inner chamber of drilling rod 1 through threaded connection's mode, survey geological through the soil in the screw thread thief rod 4.
Wherein, the external diameter of first circular fixture block 5 is greater than the external diameter of second circular fixture block 8, and the outer wall of second circular fixture block 8 is laminated with the inner wall of screw thread thief rod 4 mutually.
In this embodiment, because first circular fixture block 5 is installed in the bottom of screw thread thief rod 4, the inner chamber at screw thread thief rod 4 is installed through rotating in the bottom of round bar 7 to the circular fixture block 8 of second, is greater than the external diameter of second circular fixture block 8 with the external diameter of first circular fixture block 5 then. Because round bar 7 drives the circular fixture block 8 of second and rotates, when the soil of 4 inner chambers of screw thread thief rod needs from carrying out the geological survey time measuring, rotate the position that does not set up second fan-shaped groove 9 on the circular fixture block 8 of second through round bar 7 and fill up first fan-shaped groove 6 on the circular fixture block 5, can prevent like this to have soil to drop when taking out the soil of 4 inner chambers of screw thread thief rod from drilling rod 1 with screw thread thief rod 4 through rotating hand (hold) 10 and carrying out the geological survey, thereby guarantee the integrality of soil in the screw thread thief rod 4 and improve user's detection efficiency and accuracy.
Wherein, welding spots 12 are welded on the outer walls of the drill rod 1 and the drill bit 11.
In this embodiment, all weld welding spot 12 through on the outer wall with drilling rod 1 and drill bit 11 to there has been the space between drilling rod 1 and drill bit 11, has reduced the probability that the sand locked when taking out drilling rod 1 in the sand, reduced the friction area and reduced frictional resistance.
The working principle is as follows: when the user need take a sample and survey geology, can install this device on a certain machinery earlier, round bar 7 with the 4 inner chambers of screw thread thief rod rotates, can drive second sector groove 9 on the circular fixture block 8 of second and first sector groove 6 on the circular fixture block 5 of first circle to communicate with each other simultaneously, at this moment, drill rod 1 is crept into in the soil through drill bit 11, soil can be through half sector groove 3 on the drill rod circular fixture block 2 of drill rod 1 inner chamber bottom and the first sector groove 6 on the first circular fixture block 5 of screw thread thief rod 4 inner chamber bottom and second sector groove 9 on the circular fixture block 8 of second enter into screw thread thief rod 4, soil when needing to take out in the screw thread thief rod 4 carries out geology survey time, round bar 7 in the rotation screw thread thief rod 4 drives the circular fixture block 8 to rotate, the part that does not open second sector groove 9 on the circular fixture block 8 can first circular fixture block 5 first sector groove 6, through the equal welded solder joint 12 on drill rod 1 and drill bit 11, thereby taken out the drill rod 1 and 11 between the drill rod, at this moment, the internal friction probability of taking out of the drill rod can reduce the drill rod 4 internal friction sample and guarantee that the drill rod 4 internal friction sample the drill bit and the soil friction, thereby the drill bit can reduce the drill rod 4 internal friction and the soil sample the efficiency.
Although the embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that: various substitutions, changes and modifications are possible without departing from the spirit and scope of the invention and the appended claims, and therefore the scope of the invention is not limited to the embodiments disclosed.
