The conveying mechanism 201 is provided with a conveying assembly 2011 conveyed along the transverse direction, the steel chisel seat 202 is detachably arranged on the conveying assembly 2011, and the steel chisel seat 202 is provided with a plurality of fixing structures capable of fixing the bottom end of the steel chisel 6 at intervals along the longitudinal direction; the correcting mechanism 203 is arranged right above the conveying mechanism 201, and the correcting mechanism 203 is provided with correcting structures which correspond to the fixing structures one by one and are used for avoiding the bending deformation of the steel rods 6 on the steel rod seat 202.

At the cutter, before the sleeve interlude work, fix drill rod 6 on drill rod seat 202 earlier, make drill rod 6 carry along with transport assembly 2011, when drill rod 6 carries to the station of interlude, transport assembly 2011 stop operation, make drill rod 6 stop on the station of interlude, the rethread cutter snatchs unit 4 and carries out the cutter and alternate work, be about to cutter and sleeve alternate on drill rod 6 one by one, the cutter on drill rod 6, the sleeve alternates and starts transport assembly 2011 after filling, carry out the work of interlude of next batch drill rod 6. However, during the tool insertion process, the drill rod 6 is generally soft and flexible, so that the top end of the drill rod 6 and the expected insertion point of the tool grasping unit 4 often have a large difference. Therefore, in this embodiment, by additionally arranging the correction mechanism 203 on the conveying mechanism 201, since the correction mechanism 203 is provided with the correction structure corresponding to the drill steel 6 in a one-to-one manner, the bending deformation of the drill steel 6 on the drill steel seat 202 can be effectively avoided, so that the top end of the drill steel 6 can correspond to the position of the cutter grabbing unit 4, the cutter insertion work of the cutter grabbing unit 4 can be completed without increasing the strength of the drill steel 6, and the cutter insertion efficiency is effectively improved while the cost is saved.

In this embodiment, the correction structure includes a first correction groove 2031, a second correction groove 2032, and a third correction groove 2033 located on the same vertical plane; the first correction groove 2031 and the third correction groove 2033 are both lateral grooves, the first correction groove 2031 is located at the conveying upstream of the conveying assembly 2011 and near the conveying assembly 2011, and the third correction groove 2033 is located at the conveying downstream of the conveying assembly 2011 and far away from the conveying assembly 2011; the second correction groove 2032 is an oblique groove, and one end of the second correction groove 2032 is connected to the upstream end of the first correction groove 2031, and the other end is connected to the downstream end of the third correction groove 2033, that is, the first correction groove 2031, the second correction groove 2032, and the third correction groove 2033 together form a Z-shaped groove.

In the tool inserting process, an inserting station is provided in the middle of the third correction groove 2033 or at a position near the downstream end. Since the bottom end of the drill rod 6 is fixedly connected to the drill rod seat 202, the bending deformation amplitude of the drill rod 6 is gradually increased from bottom to top, that is, the drill rod 6 closer to the lower part is deformed less, and therefore, the first correcting groove 2031 is selected to be arranged at a position close to the conveying assembly 2011, so that the drill rod 6 can smoothly enter the correcting structure. After the drill steel 6 enters the correcting structure, because the second correcting groove 2032 is an inclined groove, the drill steel 6 is gradually straightened along with the rise of the height of the second correcting groove 2032 in the conveying process, and finally stops at the middle part of the third correcting groove 2033 or the position close to the downstream end, so that the correcting work is completed.

when the steel chisel 6 moves to the inserting station along with the conveying unit 2, the conveying unit 2 stops running, and at the moment, although the curvature of the steel chisel 6 is preliminarily corrected by the correcting mechanism, a certain difference still exists between the top end of the steel chisel 6 and the expected inserting point position of the cutter grabbing unit 4; then, the first board 502 is driven to slide towards the inside of the base 501, and the second board 503 is driven to slide towards the outside of the base 501, so that the sectional area of the positioning hole 504 is maximized; then the whole drill rod positioning unit 5 is driven to descend, so that the top end of the drill rod 6 passes through the positioning hole 504 and then is positioned above the positioning hole 504, and at the moment, the drill rod 6 is in an unclamped state; then, the first plate 502 is driven to slide towards the outside of the base 501, and the second plate 503 is driven to slide towards the inside of the base 501, so as to reduce the sectional area of the positioning hole 504, so that the drill rod 6 is clamped by the opening 5021 and the two V-shaped grooves on the through hole 5031, and the drill rod 6 can be aligned with the tool catching unit 4, i.e. the subsequent tool inserting operation can be performed.

When the tool grabbing unit 4 clamps a tool and is inserted into the drill steel 6 through the top end of the drill steel 6, the tool or the sleeve falls on the first plate 502 or the second plate 503 and cannot fall continuously, so that after one tool or sleeve is inserted, the first plate 502 is driven to slide towards the inside of the base 501, and the second plate 503 is driven to slide towards the outside of the base 501, so that the sectional area of the positioning hole 504 is maximized, and the tool falls; then, the first plate 502 is driven to slide in the direction of the outside of the base 501, the second plate 503 is driven to slide in the direction of the inside of the base 501, and the next tool or sleeve is inserted after the drill rod 6 is clamped. After the drill steel 6 is fully inserted with the tool and the sleeve in the repeated reciprocating mode, the sectional area of the positioning hole 504 is controlled to be the largest, the drill steel positioning unit 5 is driven to ascend integrally, the drill steel 6 is separated from the positioning hole 504, workers can take away the drill steel 6 conveniently or the drill steel 6 is conveyed away by a driving belt, and then the next batch of drill steel 6 is inserted.

In the embodiment, the first plate body 502 and the second plate body 503 which can move back and forth in the transverse direction are arranged on the base 501, and the opening 5021 on the first plate body 502 and the through hole 5031 on the second plate body 503 enclose the positioning hole 504, when the drill rod 6 performs the cutter insertion work, the drill rod 6 penetrates into the positioning hole 504, because the first plate body 502 and the second plate body 503 can move back and forth in the transverse direction, when the first plate body 502 and the second plate body 503 move in opposite directions, the drill rod 6 can be clamped and fixed in the process of changing the sectional area of the positioning hole 504, so that the drill rod 6 can be aligned with the cutter grabbing unit 4, the cutter insertion work of the cutter grabbing unit 4 can be completed without increasing the strength of the drill rod 6, and the cutter insertion efficiency is effectively improved while the cost is saved.
