Further, different from the symmetrical arrangement form of the conventional hopper 1, in the present embodiment, as shown in fig. 5 and fig. 6, the streamline curved section 121 on the left side and the streamline curved section 121 on the right side are arranged in a vertically staggered manner, for example, the top end of the left concave curved rod section is located above the top end of the right concave curved rod section (preferably, the lengths of the streamline curved sections 121 on both sides are designed to be the same, and the top end of the left convex curved rod section is located above the top end of the right convex curved rod section); based on this structure, guarantee that top-down has long enough streamlined cell wall in holding the silo, when not increasing and hold the silo height, can improve the smooth and easy nature of iron borer unloading fully, simultaneously, this kind of structural design also can transmit the gravity load of iron borer 3 for the work or material rest 11 of storing up borer hopper 1 effectively, avoid storing up the material pressure in brazing filler metal hopper 1 too big and lead to iron borer 3 to block down and be difficult for dredging the operation after hindering with iron borer 3 card on the one hand, on the other hand, can avoid iron borer feeding agencies 2 of below to bear great material pressure and influence its life.
As shown in fig. 5 and 6, the discharging channel of the discharging section is preferably a vertical channel, for example, a rectangular channel, and the guiding direction/height direction of the channel is parallel to the vertical direction; the width through designing the unloading passageway is less than the twice of iron borer diameter, can guarantee that 3 roots of iron borers are gone to one by one the unloading, and the further preferred width that is slightly greater than the diameter of iron borer 3 of this unloading passageway to guarantee that iron borer 3 smoothly goes down as the prerequisite, can avoid iron borer 3 to appear the phenomenon of blocking in the unloading section.
The above-mentioned brazing filler metal feeding unit is further optimized, as shown in fig. 1, fig. 2, fig. 5 and fig. 6, the brazing filler metal reclaiming mechanism 2 includes a plurality of material taking trays 21 sequentially arranged along the length direction of the material receiving groove and a rotary driving structure 22 for driving each material taking tray 21 to rotate between the material taking position and the material discharging position, the axis of the material taking tray 21 is parallel to the length direction of the material receiving groove, and a material taking groove 211 is formed on the material taking tray 21; and the material taking position is in butt joint with the outlet end of the blanking channel by the material bearing groove. In an alternative embodiment, as shown in fig. 1 and 2, the number of take-off trays 21 is the same as the number of single-sided side blanking brackets 13. In one embodiment, the depth of the material taking groove 211 is the same as the diameter of the iron rod 3, and ideally, when the material taking disc 21 is at the material taking position, a single iron rod 3 falls into the material taking groove 211, and the top end of the iron rod 3 is flush with the top end of the material taking disc 21 and the bottom end of the blanking section, but a small error is also within an allowable range, for example, the top end of the iron rod 3 slightly protrudes out of the top end of the material taking disc 21.
It can be understood that the above-mentioned material-taking groove 211 is opened on the rim/circumferential outer wall of the material-taking disc 21; drive the charging tray 21 through above-mentioned rotary drive structure 22 and rotate, when the charging tray 211 docks with the unloading passageway, the charging tray 21 acquires an iron borer 3, and when rotary drive structure 22 drove the charging tray 21 further rotation, the charging tray 211 was kept away from the unloading passageway, and other dish edges of charging tray 21 can shutoff unloading passageway to the unloading of other iron borers 3 has been stopped.
Of course, the above-mentioned structure of arranging a plurality of material taking trays 21 is not limited, and for example, it is also possible to use an integral roller (the axis of the roller is parallel to the length direction of the material receiving groove, and the length of the roller can be the same as or similar to the length of the material receiving groove). The method of rotationally discharging the material taking tray 21 by the rotational driving mechanism 22 is not limited, and it is also possible to push out the iron rod 3 in the material taking groove 211 by a push rod or the like, for example.
Preferably, the material taking plates 21 rotate synchronously, so that the material taking grooves 211 can be positioned at the material taking position at the same time to take materials normally, and the damage to the iron rod 3, the material taking plates 21 and the like is avoided; for example, the take-up trays 21 are connected by couplings 23. The above-mentioned rotary driving structure 22 may adopt a conventional rotary driving device such as a motor, and the detailed structure thereof is omitted here.
In order to further optimize the above embodiment, the two discharging positions are respectively arranged at two sides of the material taking position, and the rotary driving structure 22 can drive each material taking plate 21 to rotate bidirectionally, that is, each material taking plate 21 can rotate clockwise and can also rotate anticlockwise, so that the obtained iron rod 3 can be discharged to one of the discharging positions. Obviously, the design can supply the iron rod 3 to the two taphole drilling machines, can better adapt to the production requirement of multi-taphole process conditions, and reduces the number of iron rod supply units, thereby reducing the occupied space of stokehole equipment. When the rotary driving structure 22 is driven by a motor, the motor capable of rotating forward and backward is adopted; other rotary drives may be designed accordingly, which is not illustrated here.
In order to further optimize the above embodiment, as shown in fig. 5 and fig. 6, each of the material taking trays 21 is respectively provided with a guide shell 24 extending from the material taking position to the material discharging position, the guide shell 24 is fixed on the brazing filler metal hopper 1 (for example, mounted on the material rack 11), the guide shell 24 is sleeved on the periphery of the corresponding material taking tray 21, and the width of an arc-shaped channel defined between the two is smaller than the radius of the brazing filler metal 3. It will be appreciated that the inner wall of the guide housing 24 is an arc-shaped inner wall, and thus can form an arc-shaped channel with the take-up tray 21. The effect of above-mentioned direction shell 24 lies in preventing that iron borer 3 from getting the silo 211 in roll-off, guarantees to get the material dish 21 and gets the material back from getting the material level, can transport the iron borer 3 that acquires to the position of unloading that corresponds. When the groove depth of the material taking groove 211 of the material taking disc 21 is not less than the diameter of the iron rod, the closer the guide shell 24 is to the material taking disc 21, the better; when the groove depth of the material taking groove 211 is smaller than the diameter of the iron rod, the closer the distance between the guide shell 24 and the material taking disc 21 (i.e. the width of the arc-shaped channel) is, the better the difference between the diameter of the iron rod and the groove depth of the material taking groove 211 is. The guide shell 24 can be a cylindrical shell 24, and the avoidance design can be carried out at the material taking position and the material discharging position.
Further optimizing the above embodiment, as shown in fig. 1, fig. 2, fig. 5 and fig. 6, the discharging position is provided with the discharging guide 25, and the discharging guide 25 extends from the discharging position to the direction far away from the material taking tray 21, so that the drill rod replacing unit can conveniently take the drill rod, and the collision and interference between the drill rod replacing unit and the material taking tray 21 and the like are avoided. When there are two discharge positions, there are two discharge guides 25. In one embodiment, the discharging guide 25 is an L-shaped guide rod, which is mounted on the brazing filler metal hopper 1 (e.g., on the frame 11) or on the iron brazing filler metal reclaiming mechanism 2 (e.g., on the base 26 of the material taking tray 21, the material taking tray 21 can be mounted on the base 26 through a bearing 27 with a seat), and the turning part of the L-shaped guide rod forms a V-shaped groove, which can stably support the iron brazing filler metal 3.

The scheme is particularly suitable for the scheme that the brazing filler metal storage hopper 1/the material bearing groove adopts a frame structure; and when the drill rod storage hopper 1/the material bearing groove does not adopt a frame structure, a window can be correspondingly arranged on the material bearing groove to allow the anti-blocking push plate 41 to move.
