Detailed implementation mode

[0024] Embodiment 1

[0025] As Figures 1 to 4 shown, a spiral conveying device proposed by the present invention includes a conveying box, an intelligent monitoring device 2, a material leveling mechanism, and an angle adjustment mechanism; a spiral feeding rod 3 is rotatably connected inside the conveying box, and the spiral feeding rod 3 is driven to rotate by a driving mechanism installed outside the conveying box. One end of the top of the conveying box close to the driving mechanism is provided with a feeding pipe 102; the intelligent monitoring device 2 is arranged on the conveying box, and multiple groups of cameras in the intelligent monitoring device 2 are evenly distributed at the top end inside the conveying box; the material leveling mechanism is arranged inside the conveying box and above the spiral feeding rod 3; multiple groups of angle adjustment mechanisms are provided. The angle adjustment mechanism is detachably installed on the material leveling mechanism through bolts and corresponds to the flow guiding plate 503. The angle adjustment mechanism is composed of a driving component and a rubber seat 608 installed on the driving component. The rubber seat 608 is driven by the driving component to approach or move away from the flow guiding plate 503 for adjustment, and the rubber seat 608 abuts against the flow guiding plate 503.

[0026] The material leveling mechanism includes a connecting shaft 501, a rotating seat 502, and a flow guiding plate 503; multiple groups of connecting shafts 501 are adjustably arranged in the conveying box; the rotating seat 502 is rotatably connected to the connecting shaft 501 through a bearing, and two groups of rotating seats 502 are provided; the flow guiding plate 503 is connected to the bottom ends of the two groups of rotating seats 502 through bolts, and the bottom end of the flow guiding plate 503 is arranged close to the spiral blade in the spiral feeding rod 3.

[0027] Furthermore, a connecting pipe 103 is installed at the top of the conveying box, and the output end of the connecting pipe 103 is connected to an external dust suction mechanism for absorbing the dust generated during the conveying inside the conveying box and reducing pollution.

[0028] Further, the conveying box is composed of a box body 1 and a cover body 101. One end of the cover body 101 is hinged to the box body 1 through a hinge, and the other end of the cover body 101 is detachably connected to the box body 1 through a fastening bolt. The intelligent monitoring device 2, the feeding pipe 102 and the connecting pipe 103 are all arranged on the cover body 101. The arrangement of the cover body 101 and the box body 1 facilitates regular maintenance and cleaning of the inside of the conveying box, providing convenience for use.

[0029] Further, a plurality of groups of diversion grooves are formed in the diversion plate 503. The diversion grooves are radially distributed, and the groove depth gradually decreases from the center to the outside. The diversion grooves are used to guide the material conveyance.

[0030] Further, the driving assembly includes an installation box 6, a third threaded rod 603, a moving pipe 605, a limiting seat 601 and a rubber seat 608; the installation box 6 is installed on one of the installation seats 4 in the material leveling mechanism through bolts; the third threaded rod 603 is rotatably connected to the installation box 6, and one end of the third threaded rod 603 extends into the installation box 6 and is installed with a set of bevel gears 604. Another set of bevel gears 604 is rotatably connected to the installation box 6 through a stepping motor drive. The two sets of bevel gears 604 are meshed and connected; the moving pipe 605 is threadedly sleeved on the outer peripheral surface of the third threaded rod 603, and a sliding plate 602 is installed at the bottom end of the moving pipe 605; the limiting seat 601 is installed on the installation box 6, and the sliding plate 602 slidably penetrates through the limiting seat 601; the rubber seat 608 is installed at the other end of the moving pipe 605.

[0031] Furthermore, an elastic member 607 is arranged in the inner cavity of the moving pipe 605. The other end of the elastic member 607 is connected with a sliding rod 606. The sliding rod 606 is slidably connected to the inner cavity of the moving pipe 605, and the other end of the sliding rod 606 is connected with the rubber seat 608. Through the adaptive adjustment of the elastic member 607, it is convenient to reduce the impact force between the diversion plate 503 and the rubber seat 608, and it is convenient for the diversion plate 503 to adapt to the material particles.

[0032] In this embodiment, according to the positions of the spiral blades in the spiral feeding rod 3, multiple groups of connecting shafts 501 are adjusted to appropriate positions relative to the box body 1, such that the bottom end of the deflector plate 503 is located between two adjacent spiral blades in the spiral feeding rod 3, and the deflector plate 503 is arranged close to the spiral blade at the input end. Then, an appropriate number of mounting boxes 6 are installed on the mounting seat 4 through bolts, such that the rubber seats 608 on the mounting boxes 6 correspond to the deflector plate 503. The material is poured into the box body 1 through the feed pipe 102. The spiral feeding rod 3 is driven to rotate by the driving mechanism to convey the material towards the output end of the box body 1. At the same time, each group of cameras in the intelligent monitoring device 2 takes pictures and monitors the material in the box body 1, and the monitoring information is transmitted to the controller. The controller starts the stepping motor to drive the bevel gear 604 to rotate the third threaded rod 603. Under the guiding action of the limit seat 601 and the sliding plate 602, the moving pipe 605 moves away from or close to the third threaded rod 603, thereby driving the rubber seat 608 to abut against the deflector plate 503, causing the deflector plate 503 to rotate along the connecting shaft 501. Thus, the deflector plate 503 rotates away from or close to the spiral blade on the spiral feeding rod 3 for adjustment. The rotation angle range of the deflector plate 503 is set between 0 degrees and 45 degrees. According to the monitoring situation of the cameras in the intelligent monitoring device 2, when the material particles conveyed by the spiral blade on the spiral feeding rod 3 are relatively large, the driving assembly is used to drive the rubber seat 608 to push the deflector plate 503 to rotate upward along the connecting shaft 501, increasing the angle between the deflector plate 503 and the spiral blade, widening the material channel, and facilitating the conveyance of large-particle materials. When the material particles conveyed by the spiral blade on the spiral feeding rod 3 are relatively small, the driving assembly is used to drive the rubber seat 608 away from the deflector plate 503, and the deflector plate 503 rotates downward along the connecting shaft 501 under its own gravity, reducing the angle between the deflector plate 503 and the spiral blade, enhancing the deflector concentration, and facilitating the conveyance of small-particle materials. Thus, dynamic adjustment is achieved, and the conveying uniformity of materials with different particle sizes is improved.

[0033] Embodiment Two

[0034] As Figures 1 to 3 and Figure 5As shown in the figure, a screw conveyor device proposed by the present invention, compared with the first embodiment, the inner wall of the box body 1 in the conveying box is provided with an adjusting mechanism for adjusting the positions of multiple connecting shafts 501 on the box body 1. The adjusting mechanism includes a mounting seat 4, a mounting groove 401 and a second threaded rod 404. There are two sets of mounting seats 4. On one set of mounting seats 4, two sets of first threaded rods 402 are symmetrically threadedly connected. The first threaded rods 402 are rotatably connected to the inner wall of the box body 1. On the other set of mounting seats 4, two sets of guide rods are symmetrically slidably connected. The guide rods are mounted on the side wall of the box body 1. Two nuts are threadedly connected to the outer peripheral surface of the first threaded rod 402. One set of nuts abuts against the top end of the mounting seat 4, and the other set of nuts abuts against the bottom end of the mounting seat 4, which is used to limit and support the mounting seat 4, reduce the load on the first threaded rod 402 and extend the service life. The mounting groove 401 is arranged on the mounting seat 4. Multiple sliding seats 5 are slidably connected inside the mounting groove 401. Two sets of corresponding sliding seats 5 in the two sets of mounting seats 4 are both connected to a set of connecting shafts 501. A plurality of screw holes 403 are uniformly arranged on one set of mounting seats 4. The screw holes 403 communicate with the corresponding mounting grooves 401. The second threaded rod 404 is threadedly connected to the screw holes 403, and the bottom end of the second threaded rod 404 extends into the mounting groove 401 and is inserted into the jack on the sliding seat 5. A C-shaped rubber block abuts against the outer peripheral surface of the second threaded rod 404. The C-shaped rubber block abuts against the top end of the mounting seat 4, which is used to limit the second threaded rod 404 and improve the stability of the second threaded rod 404 to prevent it from rotating without external force adjustment.

[0035] Furthermore, a plurality of support seats are installed on the inner wall of the box body 1 by bolts. The first threaded rod 402 is rotatably connected to the support seat through a bearing. The guide rod is installed on the support seat. A guide strip is installed on the side wall of the mounting seat 4. A guide groove 104 is arranged on the inner wall of the box body 1. The guide strip is slidably connected to the guide groove 104. The top end of the guide groove 104 is open. When the bolts between the support seat and the box body 1 are removed, the mounting seat 4 can be slid upward along the guide groove 104 and taken out, and then the material leveling mechanism can be taken out, which is convenient for disassembly and maintenance.

[0036] In this embodiment, rotate the first threaded rod 402 to make the mounting seat 4 slide upward along the guide groove 104 and the box body 1 to an appropriate position, and rotate the second threaded rod 404 to move it away from the jack on the sliding seat 5. Then, the two groups of sliding seats 5 on the connecting shaft 501 can slide to appropriate positions along their respective corresponding mounting grooves 401. Adjust an appropriate number of connecting shafts 501 between the two groups of mounting seats 4 to the mounting positions according to the needs of material conveying. Thread the second threaded rod 404 into the corresponding threaded hole 403 and insert it into the jack on the sliding seat 5, thereby completing the installation of the connecting shaft 501. Then, connect the deflector 503 to the rotating seat 502 on the corresponding connecting shaft 501. Next, rotate the first threaded rod 402 to make the mounting seat 4 move downward along the box body 1 until the bottom end of the deflector 503 is located between two adjacent spiral blades in the spiral feeding rod 3, and the deflector 503 is arranged close to the spiral blade at the input end. At this time, the adjustment of the material leveling mechanism can be completed.
