Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, specifically to an iron powder production conveying equipment. Background Technology

[0002] Iron powder is a fine granular substance made of pure iron, mainly composed of two categories: reduced iron powder and atomized iron powder. It is mainly used as a metallurgical raw material, chemical catalyst, powder metallurgy product, and food fortifier. In the production and processing of iron powder, it is necessary to continuously transport the iron powder for various processing steps, so reliable conveying equipment is required.

[0003] In actual production, the feed inlet of iron powder processing equipment is mostly installed on the upper part of the equipment. As the output per unit time increases, the size of the equipment also increases, making the feed inlet even higher. The iron powder raw material used for processing needs to be transported from low to high, and the discharge port of the conveying device needs to be able to accurately connect with the feed inlet at the higher part of the target equipment. Existing conveying equipment used for iron powder production is not convenient for effectively adjusting the position and orientation of the discharge port, resulting in the inability to effectively connect with the feed inlet of the target equipment. Therefore, we propose an iron powder production conveying device. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide an iron powder production and conveying equipment. This equipment features a reliable coil conveying unit capable of lifting and conveying iron powder filled in the filling trough to the feed inlet at a higher position on the target equipment. It also has a reliable discharge adjustment unit, with fixed supports that limit and fix the tail of the lifting pipe. The vertical tilt angle of the lifting pipe can be adjusted by adjusting the extension and horizontal position of the split support columns. When the bottom retractable frame is retracted into the trough, the equipment achieves positional fixation through the friction between the frame body and the ground. When the frame body is pushed downwards, four rolling steel balls contact the ground, allowing the equipment to move and adjust its position. It can also be turned horizontally. Combined with the adjustment of the vertical angle of the lifting pipe, this ensures precise docking between the discharge port of this equipment and the feed inlet of an external docking device, effectively solving the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an iron powder production and conveying equipment, comprising a frame body, a feeding adjustment unit, and a coil conveying unit;

[0006] The main frame is a horizontally arranged cuboid structure with a filling groove on the right side inside.

[0007] Material feeding adjustment unit: includes a lifting pipe, fixed support block, connecting shaft, movable seat, split support column and hydraulic cylinder 1. An inclined lifting pipe is installed on the upper part of the frame body. The lower right end of the lifting pipe extends into the filling groove. The outer side of the lifting pipe is fixedly connected to two sets of connecting shafts, each set of connecting shafts includes two horizontal shafts, left and right. The outer end of the lower set of connecting shafts is rotatably connected to the inside of the fixed support block. The left and right fixed support blocks are fixedly connected to the upper middle part of the frame body on the right side. The outer end of the upper set of connecting shafts is rotatably connected to the inside of the split support column. The split support column consists of two columns, upper and lower. A hydraulic cylinder 1 is embedded in the lower column. The telescopic end of the hydraulic cylinder 1 is fixedly connected to the inside of the upper column with its extension end facing upward. The lower end of the split support column is fixedly connected to the upper end of the movable seat. The movable seat is a T-shaped structure and is slidably connected in a groove opened on the left side of the upper end of the frame body.

[0008] Roll conveying unit: installed inside the lifting pipe and at the upper angle.

[0009] The filling tank is used to hold the iron powder material to be conveyed. The lifting pipe uses an internally installed conveying device to transport the iron powder to a higher position, so that the iron powder can be fed into the higher feed port of the subsequent processing equipment. The connecting shaft is used to realize the rotatable connection between the lifting pipe and the two side supports. The fixed support block and the split support are used to support the tail and the upper side of the lifting pipe, respectively. The fixed support block can also limit and fix the tail of the lifting pipe. By limiting and fixing the tail of the lifting pipe, it is easy to adjust the tilt angle of the lifting pipe. The hydraulic cylinder controls the height adjustment of the split support, thereby adjusting the tilt angle of the lifting pipe. When adjusting the height, the movable seat can drive the split support to make a corresponding displacement, so as to adjust the position of the support structure according to the tilt change of the lifting pipe.

[0010] Furthermore, the coil conveying unit includes a mounting cover, a shaft mounting block, a central rotating shaft, a feeding frame, and a motor. A semi-cylindrical mounting cover is fixedly connected to the upper inclined end of the lifting pipe. A motor is installed on the inner side of the upper inclined end of the mounting cover. The tail housing of the motor is fixedly connected to the upper inclined end of the mounting cover by bolts. A shaft mounting block is fixedly connected to the lower side of the mounting cover and the lower inclined end of the lifting pipe. The central rotating shaft is rotatably connected between the two shaft mounting blocks and coincides with the central axis of the lifting pipe. A spiral feeding frame is fixedly connected to the outer side of the central rotating shaft. A notch is opened in the upper half of the lower inclined end of the lifting pipe. The output shaft of the motor is fixedly connected to the upper inclined end of the central rotating shaft through a coupling. The shaft mounting block is used for mounting the central rotating shaft. When the central rotating shaft rotates, it can drive the feeding frame to rotate, encircle the iron powder filled in the filling groove, and convey it upward along the lifting pipe. The notch at the lower end of the lifting pipe facilitates the spiral feeding frame to encircle the iron powder. The mounting cover is used for mounting the motor. The motor provides the power required for the rotation of the central rotating shaft and the feeding frame. The mounting cover is installed on the upper side of the upper end of the lifting pipe, thereby avoiding affecting the material discharge at the upper end of the lifting pipe.

[0011] Furthermore, the material feeding adjustment unit also includes a second hydraulic cylinder, a limiting slide rod, and mounting blocks. The second hydraulic cylinder is embedded in a groove on the upper left side of the main frame body. The second hydraulic cylinder is fixed to the inner front wall of the groove, with its extension end facing rearward and fixedly connected to the section of the movable seat that extends into the slot. Two sets of mounting blocks are installed on the upper end of the main frame body, with a limiting slide rod fixedly connected between the two mounting blocks in each set. The two limiting slide rods pass through the left and right ends of the T-shaped movable seat and maintain a slidable connection with it. The second hydraulic cylinder is used to press against the movable seat to ensure the position of the movable seat and the upper split support column is fixed. The second hydraulic cylinder can also actively adjust the position of the movable seat, thereby adjusting the inclination angle of the lifting pipe. The mounting blocks are used to install the limiting slide rod, which guides the movable seat and limits its movement, preventing it from detaching from the groove.

[0012] Furthermore, the feeding adjustment unit also includes a retractable base frame, a cross-shaped locking block, and rolling steel balls. An H-shaped mounting groove is provided at the lower end of the main frame body, inside which a similarly H-shaped retractable base frame is installed. A hydraulic cylinder three is embedded in the center of the main frame body, with its extension end facing downwards and a cross-shaped locking block fixedly connected to its end. The cross-shaped locking block is inserted into and locked in place at the center of the retractable base frame. A rolling steel ball is rotatably connected to each of the four corners of the lower end of the retractable base frame. When the retractable base frame retracts into the mounting groove, the main frame body can sit directly on the ground, thus utilizing greater friction to ensure the overall stability of the equipment. When the hydraulic cylinder three pushes the retractable base frame out of the bottom mounting groove, the four rolling steel balls contact the ground, at which point the equipment can be moved for easy position adjustment and horizontal turning. Combined with the adjustment of the vertical angle of the lifting pipe, this allows for precise docking of the feeding port of this equipment with the feeding port of an external docking device.

[0013] Furthermore, the feeding adjustment unit also includes a diagonal connecting rod and a hand grip. Two diagonal connecting rods are fixedly connected to the right side of the main frame, and a transverse hand grip is fixedly connected between the upper diagonal ends of the two diagonal connecting rods. The diagonal connecting rods are used for mounting the hand grip, which allows the user to easily push the equipment or adjust its direction.

[0014] Furthermore, the coil conveying unit also includes a retaining ring. An Ω-shaped retaining ring is installed on the outside of the motor, and the retaining ring is clamped to the outside of the motor. Both ends of the retaining ring are fixedly connected to the mounting cover by bolts. The retaining ring is used to reinforce the motor, thereby ensuring its long-term stable operation.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This iron powder production and conveying equipment has the following advantages:

[0016] 1. It has a reliable material discharge adjustment unit. The fixed support block has a limiting and fixing effect on the tail of the lifting pipe. By adjusting the extension and horizontal position of the split support column, the vertical tilt angle of the lifting pipe can be adjusted. When the bottom retractable frame is retracted into the groove, the equipment achieves position fixation through the friction between the frame body and the ground. When the frame body is pushed down, the four rolling steel balls contact the ground. At this time, the equipment can move, which is convenient for position adjustment and horizontal turning. With the adjustment of the vertical angle of the lifting pipe, the discharge port of this equipment can be accurately connected with the feed port of the external docking equipment.

[0017] 2. It has a reliable coil conveying unit. The lower right end of the lifting pipe extends into the interior of the filling trough. The notch at the lower angle of the lifting pipe facilitates the spiral feeder to coil up the iron powder. The motor drives the central rotating shaft and the feeder to rotate, thereby coiling up the iron powder filled in the filling trough and conveying it upward along the lifting pipe. The mounting cover is installed on the upper side of the upper angle of the lifting pipe, so as to avoid affecting the material discharge at the upper angle of the lifting pipe.

[0018] 3. This equipment has a reliable coil conveying unit, which can lift and convey the iron powder filled in the filling tank to the feed inlet at the higher position of the target equipment. It also has a reliable discharge adjustment unit. The fixed support block has a limiting and fixing effect on the tail of the lifting pipe. By adjusting the extension and horizontal position of the split support column, the vertical tilt angle of the lifting pipe can be adjusted. When the bottom retractable frame is retracted into the tank, the equipment is fixed in position by the friction between the frame body and the ground. When the frame body is pushed down, the four rolling steel balls contact the ground. At this time, the equipment can move, which is convenient for position adjustment and horizontal turning. With the adjustment of the vertical angle of the lifting pipe, the discharge port of this equipment can be accurately connected with the feed inlet of the external docking equipment.

When the middle rotating shaft 43 rotates, it can drive the feeding frame 44 to rotate, coil up the iron powder filled in the filling trough 2, and convey it upward along the lifting pipe 31. The notch at the lower end of the lifting pipe 31 can facilitate the spiral feeding frame 44 to coil up the iron powder; the mounting cover 41 is used for the installation of the motor 45. The motor 45 is used to provide the power required for the rotation of the middle rotating shaft 43 and the feeding frame 44. The mounting cover 41 is installed on the upper side of the upper end of the lifting pipe 31, so as to avoid affecting the discharge of the upper end of the lifting pipe 31; the retaining ring 46 is used to reinforce the motor 45, thereby ensuring that it can work stably for a long time. This equipment also features a reliable coil conveying unit 4, supporting equipment displacement adjustment and flexible orientation of the discharge port, facilitating docking with the feed inlet of the target equipment. The filling trough 2 holds the iron powder to be conveyed, and the lifting pipe 31 uses internally installed conveying equipment to transport the iron powder to a higher position, allowing it to enter the higher feed inlet of the subsequent processing equipment. The connecting shaft 33 enables the rotatable connection between the lifting pipe 31 and the two side supports. The fixed support block 32 and the split support column 35 are respectively used to support the tail of the lifting pipe 31.

By limiting and fixing the tail of the lifting pipe 31, it is convenient to adjust the tilt angle of the lifting pipe 31; the hydraulic cylinder 36 controls the height adjustment of the split support column 35, thereby adjusting the tilt angle of the lifting pipe 31; and when adjusting the height, the movable seat 34 can drive the split support column 35 to make corresponding displacement, so as to adjust the position of the support structure according to the tilt change of the lifting pipe 31; the hydraulic cylinder 37 is used for The movable seat 34 is tightened to ensure that the positions of the movable seat 34 and the upper split support column 35 are fixed. The position of the movable seat 34 can be actively adjusted by the hydraulic cylinder 37, thereby adjusting the tilt angle of the lifting pipe 31. The mounting block 39 is used for the installation of the limiting slide bar 38. The limiting slide bar 38 can guide the movable seat 34 and limit the movable seat 34 to prevent it from falling out of the slide groove. When the retractable base frame 312 is retracted into the mounting groove, it allows the main body of the frame 1 to sit directly on the ground. The surface utilizes greater friction to ensure the overall stability of the equipment. The inclined connecting rod 310 is used for the installation of the hand grip rod 311, which allows the user to easily push the equipment or adjust the equipment for steering.
