[0045] The central axis support column 400 is constructed as follows Figures 3 to 6 As shown, see Figure 3 , including a central connecting body 100 and a plurality of supporting plates 401 arranged around the central connecting body 100, wherein the supporting plates 401 are rectangular plate-shaped structures, each of the supporting plates 401 is respectively provided with a male buckle 402 and a female buckle 403, and the adjacent supporting plates 401 are connected via the male buckle 402 and the female buckle 403.

[0046] See Figure 5 and 6 The central connector 100 includes a support plate 101 and a tensile plate 106. The support plate 101 is a regular polygonal plate-shaped structure. A plurality of through grooves 103 are provided through the two end surfaces of the support plate 101. The plurality of support plates 101 are arranged in parallel. The at least one tensile plate 106 connects the plurality of support plates 101 through the through grooves 103. The support plate 401 is arranged around the side of the support plate 101. By arranging the central connector 100 in the middle of the surrounding support plate 401, the central connector 100 can play a good supporting role on the support plate 401, which is beneficial to improving the overall structural strength of the support plate 401 and ensuring the tensile resistance of the support plate 401. Among them, by arranging the through grooves 103 in the support plate 101, the tensile plate 106 can be arranged in the through grooves 103 of the plurality of support plates 101. The tensile plate 106 can connect the plurality of support plates 101 to strengthen their structure, which is beneficial to the overall structural strength of the central axis support column 400.

[0047] See Figure 4The male buckle 402 includes two male plates 404 arranged in parallel, and the female buckle 403 includes two female plates 405 arranged in parallel. The male plates 404 and the female plates 405 are both rectangular plate-shaped structures. The male plates 404 and the female plates 405 are respectively arranged on both sides of the support plate 401. The side of each male plate 404 away from the support plate 401 is provided with an outer hook 406, and the outer hook 406 is convexly arranged away from the other male plate 404. The side of each female plate 405 away from the support plate 401 is provided with an inner hook 407. The inner hook 407 is set inwardly away from the other mother plate 405, and the two support plates 401 are clamped together by the concave inner hook 407 and the convex outer hook 406. By setting the male buckle 402 and the female buckle 403 so that the outer hook 406 of the male plate 404 is clamped with the inner hook 407 of the mother plate 405, it is beneficial to clamp the adjacent support plates 401, so that the connection between the support plates 401 is more stable, and it is helpful to better connect the support member or support rod spirally arranged on the outer surface of the central axis support column 400 to the support plate 401 through bolts.

[0048] The support plate 401 has an arc surface 411 on one side facing outward, the highest point of the arc surface 411 is located in the middle, and the lowest point of the arc surface 411 is connected to other support plates 401. By providing the arc surface 411 on the side facing outward of the support plate 401, the outer contour of the surrounding support plate 401 is closer to the cylindrical side, which helps to better connect the support member or support rod spirally arranged on the outer surface of the central axis support column 400 to the support plate 401 through bolts.

[0049] The support plate 401 is provided with a slide groove 408 on one side facing outwards, a slider 409 is slidably arranged in the slide groove 408, the slide groove 408 and the slider 409 are both convex in shape, a plurality of through holes 204 are provided in the slide groove 408, and a through hole 204 is also provided on the slider 409, a threaded hole is provided on the side of the support plate 101, the support plate 401 and the slider 409 are fixedly connected to the side of the support plate 101 by bolts, and each slider 409 is also provided with a threaded hole, A slide groove 408 is provided on the side, a slider 409 is slidably set in the slide groove 408, and a plurality of threaded holes are provided in the slide groove 408, so that the slider 409 can be set in the slide groove 408 by bolts to form a spiral ascending shape, and threaded holes are provided on the slider 409, so that it can serve as a fixing basis for the support member or the support rod, and the position of the support member or the support rod of the screw conveyor can be accurately determined by the position of the threaded holes in the slide groove 408. Compared with directly drilling holes and grooves on the arc surface 205, the position is more precise, the adjustability is stronger, and it is also convenient for replacement and repair.

[0050] See Figure 5The side surfaces of the support plate 101 are respectively provided with a rectangular groove 102 extending to the two end surfaces, and the rectangular groove 102 is provided at the threaded hole on the side surface of the support plate 101. By providing the rectangular groove 102 on the side surface of the support plate 101 with the threaded hole, it is helpful to reduce the contact area between the side surface of the support plate 101 and the plate on the central axis support column 400 (when the planes of the two plates are in contact, the larger the contact area, the higher the required plane processing flatness, otherwise it is easy to be uneven), thereby improving the connection tightness between the side surface of the support plate 101 and the plate on the central axis support column 400.

[0051] It also includes a sleeve 410. The sleeve 410 is arranged on the outside of the plurality of support plates 401. The sleeve 410 is fixedly connected to the outside of the support plate 401 by bolts. By arranging the sleeve 410 outside the surrounding support plate 401, the sleeve 410 is fixedly connected to the outside of the support plate 401 by bolts. Since the support plate 401 is mainly subjected to outward pulling force, the setting of the sleeve 410 greatly enhances the tensile strength.

[0052] The support plates 401 are provided with eight pieces, and the arc surfaces 411 of the eight support plates 401 are pieced together to form a side surface close to a cylinder. By surrounding the eight support plates 401, a nearly circular shape can be effectively formed, which is conducive to the support rods or support members of the screw conveyor being arranged in a spiral ascending form on the outside of the support plates 401. Assuming that there are fewer support plates 401, the outer sides of the surrounding support plates 401 are not close to a circle, and it is difficult to set a spiral conveyor belt 2 and its support members.

[0053] The support plate 101 is also provided with reinforcing ribs 105 . By providing the reinforcing ribs 105 on the support plate 101 , the structural strength of the support plate 101 is improved, which is beneficial to improving the overall tensile strength of the central axis support column 400 .

[0054] The bottom of the tensile plate 106 is fixedly connected to the support base 1 of the screw conveyor. By fixing the bottom of the tensile plate 106 to the support base 1 of the screw conveyor, the structural strength of the central axis support column 400 is improved as a whole.

[0055] The supporting member 500 is constructed as follows Figure 7 and Figure 8As shown, it includes a supporting plate 501 and an arc plate 503. The outer wall of the central axis support column 400 of the screw conveyor is spirally provided with a plurality of horizontally arranged supporting plates 501 from bottom to top. The arc plate 503 is an arc plate 503-shaped structure. Each arc plate 503 is respectively mounted on the supporting plate 501. The arc plates 503 are connected end to end to form a spiral track. An upper notch 504 and a lower notch 505 are respectively opened at both ends of the arc plate 503. The upper notch 504 and the lower notch 505 of the two adjacent arc plates 503 are spliced. The arc plates 503 where the upper notch 504 and the lower notch 505 are located are respectively provided with mounting holes. The supporting plate 501 is provided with corresponding threaded holes. The arc plates 503 It is connected to the supporting plate 501 through bolts and mounting holes, and upper notches 504 and lower notches 505 that can be matched and connected are respectively provided at the head and tail ends of the arc plate 503, so that multiple arc plates 503 can cooperate with each other to form a spiral track. The spiral angle of the spiral track is specifically reflected in the height difference at both ends of the arc plate 503. The upper notch 504 and the lower notch 505 of the arc plate 503 are fixed to the supporting plate 501 by bolts, so that the arc plate 503 can be better fixed, and the arc plate 503 can be fixed at the same height, which is beneficial to the transmission of the conveyor belt 2, reduces wear and tear, and is easy to disassemble and replace.

[0056] The supporting member 500 also includes a fixing plate 502 which is vertically and fixedly arranged at one end of the supporting plate 501. One end of the supporting plate 501 is fixedly connected to the fixing plate 502. A through hole 204 is opened on the fixing plate 502. The fixing plate 502 is fixedly connected to the outer wall of the central axis support column 400 of the screw conveyor by bolts. By arranging the fixing plate 502 at one end of the supporting plate 501 and opening the through hole 204 on the fixing plate 502, the fixing plate 502 can be fixedly connected to the central axis support column 400 by bolts. Each fixing plate 502 is fixedly connected to the central axis support column 400 by at least two bolts, which is beneficial to the stability of the fixing plate 502 and the supporting plate 501 fixedly connected to the fixing plate 502, thereby facilitating the transmission stability of the conveyor belt 2.

[0057] Each arc-shaped plate 503 is supported by at least three supporting plates 501 below. By arranging the arc-shaped plate 503 to at least span across three supporting plates 501, the stability of each arc-shaped plate 503 being supported is improved, wherein the arc-shaped plate 503 is provided with an upper notch 504 and a through hole 204 at a lower notch 505. At least one through hole 204 is evenly spaced on the arc-shaped plate 503 between the upper notch 504 and the lower notch 505 for connecting the supporting plates 501, so that the supporting plates 501 can provide a relatively stable supporting effect on the arc-shaped plate 503.

[0058] At least two spiral tracks are concentrically arranged. By concentrically arranging at least two spiral tracks, the supporting area of ​​the conveyor belt 2 can be increased, which is beneficial to improving the supporting stability of the conveyor belt 2.

[0059] The material of the arc plate 503 is one of metal or polyurethane rubber. By setting the material of the arc plate 503 to one of metal or polyurethane rubber, the metal material is durable and stable, and the polyurethane rubber has a certain degree of softness while having good stability, which is beneficial to reducing the vibration and rigid damage of the conveyor belt 2.

[0060] When multiple support plates 501 are spliced ​​together, the multiple support plates 501 form a nearly spiral shape, and the upper notch 504 and the lower notch 505 of the support plate 501 are seamlessly connected or have a small gap. The gap in the accompanying drawings is a visual gap provided to facilitate viewing of related features.

[0061] The highly automated split screw conveyor further comprises a horizontal conveying section 300, which is constituted as follows: Fig. 9 and Fig.10 As shown, a horizontal conveying section 300 is respectively arranged between the spiral track and the active roller 3 and the driven roller 4, the supporting side plates 301 are arranged in parallel and use the supporting base 1 or the central axis support column 400 as a fixed basis, the horizontal conveying section 300 includes supporting side plates 301, supporting pallets 302, horizontal tracks 303 and limiting components 700, two supporting side plates 301 are arranged in parallel between the driving roller and the spiral section track, a plurality of supporting pallets 302 are horizontally erected between the two supporting side plates 301, a horizontal track 303 is arranged on the supporting pallet 302, a conveyor belt 2 is arranged on the supporting track, the horizontal track 303 is connected to the spiral track of the spiral section, by erecting the supporting pallet 302 between the two supporting side plates 301, a horizontal track 303 is arranged on the supporting pallet 302, the horizontal track 303 is arranged between the spiral track of the screw conveyor and the driving roller, and the horizontal track 303 provides better support for the conveyor belt 2. The supporting side plates 301 are arranged in parallel and use the supporting base 1 or the central axis supporting column 400 as a fixed foundation.

[0062] See Fig.10The limiting assembly 700 includes a limiting platform 701, a limiting motor 702, a driving pulley 703, a synchronous belt 704, a guide pulley 705, a forward pulley 706 and a reverse pulley 707. The limiting platform 701 is rotatably provided with a driving pulley 703, a guide pulley 705, a forward pulley 706 and a reverse pulley 707. The limiting motor 702 drives the driving pulley 703 to rotate. The driving pulley 703 drives the guide pulley 705 and the forward pulley 706 to rotate through the synchronous belt 704. The guide pulley 705 is meshed with the reverse pulley 707. The forward pulley 706 and the reverse pulley 707 are respectively fixedly connected with a rotating rod 708 in the vertical direction at the axis. The upper end of each rotating rod 708 is connected with a swing rod 709 in the horizontal direction. By setting the limiting component 700, the goods on the conveyor belt 2 can be limited, the contact between the conveyor belt 2 and the baffle can be reduced, the damage to the goods can be reduced, and the stability of the goods transportation can be improved. Among them, the rotating rod 708 and the swing rod 709 are driven by driving the forward pulley 706 and the reverse pulley 707 to realize the synchronous reverse rotation of the swing rod 709, so that the swing rod 709 can be set on both sides above the conveyor belt 2 to better guide the goods.

[0063] A plurality of limiting wheels 710 are arranged at equal intervals on the two swing arms 709. By arranging a plurality of limiting wheels 710 at equal intervals on the two swing arms 709, the swing arms 709 can be guided by the limiting wheels 710 during the process of guiding the goods on the conveyor belt 2, thereby converting the sliding friction into rolling friction, thereby reducing the friction damage caused by the relative slippage between the goods.
