Description

Technical Field

[0001] The utility model relates to the technical field of screw drill tools, in particular to a fully open rotary punch screw drill tool. Background Art

[0002] The rotary percussion drill is designed to improve rock breaking efficiency. The spiral shape allows it to be easily rotated into the ground and can easily break through the rock when passing through it.

[0003] According to the existing technology, the drill tool will enter the ground when drilling, but the situation in the ground is relatively complicated, with gravel and other debris, which will have a certain impact on the drill tool during drilling. These impacts may cause the drill bit to deviate, and then cause the deviated drill bit to drive the drive shaft to deviate, thereby causing hard friction between the drive shaft and the outer wall of the drill tool, which will not only reduce the working efficiency of the drill tool, but also reduce the service life of the drill tool. In addition, when drilling, impurities in the ground will impact the sealing part of the drill tool. Ordinary sealing rings only use their own strength to block it, but this cannot be used for a long time. When the sealing ring is broken, soil enters the drill tool, which will cause friction inside the drill tool. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0005] To this end, the technical solution adopted by the utility model is: a fully open rotary percussion screw drill, comprising a shell, a fixing ring is fixedly connected to the inside of the shell, a driving shaft is rotatably connected to the inner wall of the fixing ring, one end of the driving shaft is fixedly connected to the connecting shaft, one end of the connecting shaft is fixedly connected to a stabilizing collar, one end of the stabilizing collar is fixedly connected to a fixing rod, a soft rope is fixedly connected to the outer wall of the fixing rod, one end of the soft rope is fixedly connected to a counterweight, a moving plate is slidably connected to the outer wall of the counterweight, one end of the moving plate is symmetrically fixedly connected to the moving rod, and one end of the moving rod is fixedly connected to a friction block;

[0006] One end of the connecting shaft is fixedly connected with a sealing ring, the interior of the sealing ring is hollow, the inner wall of the sealing ring is fixedly connected with a limit frame, the interior of the limit frame is slidably connected with a rolling ball, and an extrusion block is arranged on one side of the rolling ball.

[0007] Preferably, a spring is fixedly connected to one side of the movable plate, and one end of the spring is fixedly connected to the inner wall of the stabilizing ring.

[0008] Preferably, one end of the connecting shaft is fixedly connected to a spiral rod, one end of the spiral rod is fixedly connected to a rotating rod, and one end of the rotating rod is fixedly connected to a rotating head.

[0009] Preferably, one end of the shell is fixedly connected to a containing bucket.

[0010] Preferably, a connecting block is fixedly connected to the top of the shell.

[0011] Preferably, the number of the stabilizing rings is two, the number of the fixing rods corresponds to the number of the stabilizing rings, and the outer wall of the soft rope is symmetrically arranged on the outer wall of the fixing rod.

[0012] Preferably, the limiting frame is annular and fixedly connected to the inner wall of the sealing ring, and two rolling balls are arranged in each limiting frame.

[0013] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0014] 1. The utility model is provided with a stabilizing ring, and when the connecting shaft rotates, the centrifugal force can be used to drive the fixed rod to rotate. The counterweight block connected to the soft rope on the fixed rod will move under the drive of the centrifugal force, thereby pushing the movable plate to move. The movable plate drives the friction block on the movable rod to support the inner wall of the outer shell, which can play a stabilizing role. If it deviates after encountering an impact, it can automatically calibrate and return to its original position, which can prevent the equipment from deviating during operation and failing to work normally, thereby ensuring the service life of the equipment.

[0015] 2. A sealing ring is provided in the utility model. When the sealing ring is driven by the connecting shaft to rotate, it will drive the rolling ball in the limit frame to move. When the rolling ball moves, it can push the extrusion block to move. When the extrusion block moves, it can squeeze the edge of the sealing ring, thereby stretching the sealing ring to increase the strength of the sealing ring, and further filling the gap between the sealing ring and the outer shell, thereby reducing the occurrence of leakage and ensuring that impurities such as soil will not enter the interior of the equipment.

[0023] A fully open rotary screw drilling tool provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.

[0024] Combination Figure 1-4 As shown, the utility model provides a fully open rotary punch screw drill, comprising a shell 1, a fixing ring 2 is fixedly connected inside the shell 1, a driving shaft 3 is rotatably connected to the inner wall of the fixing ring 2, one end of the driving shaft 3 is fixedly connected to a connecting shaft 4, one end of the connecting shaft 4 is fixedly connected to a stabilizing collar 5, one end of the stabilizing collar 5 is fixedly connected to a fixing rod 12, an outer wall of the fixing rod 12 is fixedly connected to a soft rope 13, one end of the soft rope 13 is fixedly connected to a counterweight 14, an outer wall of the counterweight 14 is slidably connected to a moving plate 15, one end of the moving plate 15 is symmetrically fixedly connected to a moving rod 16, and one end of the moving rod 16 is fixedly connected to a friction block 17;

[0026] In the first embodiment, when the rotation of the driving shaft 3 drives the stabilizing ring 5 on the connecting shaft 4 to rotate, the centrifugal force can be used to make the soft rope 13 on the fixed rod 12 drive the counterweight 14 to lift, and when it is lifted, it will push the moving rod 16 on the moving plate 15 to move, and when the moving rod 16 moves, it will drive the friction block 17 to slide against the inner wall of the outer shell 1, so that the driving shaft 3 and the connecting shaft 4 can maintain stable rotation during the rotation process, and the internal transmission shaft will not be deflected due to the deviation caused by the drill bit encountering rocks or collision, affecting normal operation, and the spring 18 can be used to calibrate and reset after being hit, which not only plays a protective role, but also ensures that the equipment has buffering capacity and extends the service life of the equipment.

When moving, the extrusion block 21 is pushed by its own gravity. The movement of the extrusion block 21 will squeeze the side wall of the sealing ring 6, thereby stretching the sealing ring 6. The strength of the sealing ring 6 can be increased during the stretching. While increasing the strength, the elastic force of the tightened sealing ring 6 will also increase, so it can resist the impact of gravel and soil, and during the stretching process, the gap between the sealing ring 6 and the outer shell 1 can be reduced again, thereby avoiding the infiltration of liquid and ensuring the normal operation of the equipment.
