Description

Technical Field

[0001] This disclosure relates to the field of pole manufacturing technology, specifically to a pole feeding machine material distribution structure and a pole feeding machine. Background Technology

[0002] Electric poles are mostly formed by centrifugal molding of steel reinforcement frames and concrete molds. The molds are generally divided into upper molds and lower molds. In the process of use, concrete is usually poured into the lower mold first, and then the upper mold and the lower mold are closed. Finally, the concrete is centrifugally molded in the mold.

[0003] In the pole manufacturing process, existing feeding machine structures often experience concrete clumping during the feeding process, leading to blockages and poor concrete flow. Furthermore, traditional feeding structures struggle to achieve uniform concrete distribution, resulting in varying concrete densities in different parts of the pole during molding, which severely impacts the pole's processing quality and structural strength. Utility Model Content

[0004] The purpose of this disclosure is to provide a material distribution structure for a power pole feeding machine. This structure can prevent caking during the feeding process, ensure the smooth flow of concrete, and achieve uniform material distribution, which is beneficial to improving the processing quality and production efficiency of power poles.

[0005] To achieve the above objectives, this disclosure provides a material feeding structure for a power pole feeding machine, including a spiral material feeding assembly. The spiral material feeding assembly includes a shell with an open top, and a main spiral shaft and a secondary spiral shaft located within the shell. The secondary spiral shaft is provided on both sides of the main spiral shaft. The main spiral shaft and the secondary spiral shaft are respectively connected to corresponding driving components for transmission. The rotation direction of the secondary spiral shaft is opposite to that of the main spiral shaft, and the diameter of the secondary spiral shaft is smaller than that of the main spiral shaft. The main spiral shaft is provided with a first spiral blade, and the secondary spiral shaft is provided with a second spiral blade. The pitch of the first spiral blade is greater than the pitch of the second spiral blade.

[0006] Optionally, one end of the main screw shaft is the feed end and the other end is the discharge end. The pitch of the first screw blade on the main screw shaft and the pitch of the second screw blade on the auxiliary screw shaft are both variable pitch, and both are configured such that the pitch at the feed end is greater than the pitch at the discharge end.

[0007] Optionally, the shell is provided with a material hopper near the discharge end. The material hopper includes a first part and a second part. The first part is arranged vertically and its top is connected to the shell. The bottom of the first part is provided with a second part, wherein the second part is constructed as a funnel-shaped structure.

[0008] Optionally, the material feeding structure of the pole feeding machine also includes a material blocking assembly. The second part is provided with material blocking assemblies on both opposite sides. The material blocking assembly includes a material blocking plate, which extends along the axial direction of the lower mold of the pole, and the two material blocking plates are used to block the corresponding sides above the lower mold of the pole.

[0009] Optionally, the baffle assembly also includes an adjustment mechanism, with the baffle plate slidably disposed in the second part. The adjustment mechanism is connected to the baffle plate in a transmission manner so that the baffle plate can move closer to or further away from the lower die of the pole in the radial direction.

[0010] Optionally, a groove is provided parallel to the inclined surface of the second part, the groove extends from the top to the bottom of the second part, and a slider is provided on the baffle plate that slides in cooperation with the groove; the adjusting mechanism includes a lead screw, which is rotatably disposed in the groove, and the lead screw is threadedly connected to the slider.

[0011] Optionally, the baffle assembly also includes a movable plate. Both the baffle plate and the movable plate are constructed in an arc shape, and the movable plate has an arc-shaped through hole. The movable plate is fitted onto the bottom of the baffle plate through the arc-shaped through hole. The bottom surface of the movable plate is in movable contact with the upper surface of the lower die of the electric pole. The lower part of the baffle plate is threaded with a limit post to restrict the movement of the movable plate in the vertical direction.

[0012] Optionally, the baffle assembly also includes an elastic element, a stepped surface is formed between the bottom and top of the baffle plate, the elastic element is sleeved on the bottom of the baffle plate, and the elastic element abuts against the movable plate and the stepped surface.

[0013] Based on the above technical solutions, this disclosure also provides a pole feeding machine, including a frame, a feeding hopper mounted on the frame, and a pole feeding machine material distribution structure. The bottom of the frame is provided with multiple wheels, and the pole feeding machine material distribution structure is located below the feeding hopper.

[0014] Through the above technical solution, the material feeding structure of the pole feeding machine disclosed herein is equipped with a spiral feeding assembly. Since the spiral feeding assembly includes a main spiral shaft and a secondary spiral shaft with opposite rotation directions, and the pitch of the first spiral blade on the main spiral shaft is greater than the pitch of the second spiral blade on the secondary spiral shaft, the main spiral shaft can quickly transport concrete material to the feeding area, while the secondary spiral shaft can reverse comb and stir the material, so that the material is fully mixed and dispersed during the conveying process, effectively avoiding material accumulation and clumping, while avoiding blockage of the feeding machine, ensuring the smoothness of concrete material feeding, achieving uniform material distribution, and improving the processing quality and production efficiency of the pole.

[0018] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0019] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" refer to "inner" and "outer" relative to the contour of the corresponding component, and "top" and "bottom" refer to "top" and "bottom" along the height direction in the usage state of this disclosure. Furthermore, the terms "first," "second," etc., used in this disclosure are for distinguishing one element from another and do not have sequential or importance implications. In the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements. The above definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0020] According to exemplary embodiments of this disclosure, reference is made to Figures 1 to 3As shown, a material feeding structure for a power pole feeder is provided, including a spiral material feeding assembly 1. The spiral material feeding assembly 1 includes a housing 11 with an opening 10 at the top, and a main spiral shaft 12 and a secondary spiral shaft 13 located inside the housing 11. The secondary spiral shaft 13 is provided on both sides of the main spiral shaft 12. The main spiral shaft 12 and the secondary spiral shaft 13 are respectively connected to corresponding driving components for transmission. The rotation direction of the secondary spiral shaft 13 is opposite to that of the main spiral shaft 12, and the diameter of the secondary spiral shaft 13 is smaller than that of the main spiral shaft 12. The main spiral shaft 12 is provided with a first spiral blade 121, and the secondary spiral shaft 13 is provided with a second spiral blade 131. The pitch of the first spiral blade 121 is greater than the pitch of the second spiral blade 131.

[0021] In this disclosure, the driving component can be an electric motor or a hydraulic motor, as long as it can drive the main helical shaft 12 and the secondary helical shaft 13 to rotate. This disclosure does not impose any specific restrictions on this.

[0022] Through the above technical solution, in the material distribution structure of the pole feeding machine disclosed herein, a spiral material distribution assembly 1 is provided. Since the spiral material distribution assembly 1 includes a main spiral shaft 12 and a secondary spiral shaft 13 with opposite rotation directions, and the pitch of the first spiral blade 121 on the main spiral shaft 12 is greater than the pitch of the second spiral blade 131 on the secondary spiral shaft 13, the main spiral shaft 12 can quickly transport concrete material to the material distribution area, while the secondary spiral shaft 13 can reverse combing and stirring of the material, so that the material is fully mixed and dispersed during the transportation process, effectively avoiding material accumulation and clumping, while avoiding blockage of the feeding machine, ensuring the smoothness of concrete material feeding, achieving uniform material distribution, and improving the processing quality and production efficiency of the pole.

[0023] In this disclosure, the housing 11 can be constructed as a cylindrical housing, with an opening 10 extending along the axial direction of the housing 11, and the length of the opening 10 being greater than the lengths of the main helical shaft 12 and the secondary helical shaft 13, so that the main helical shaft 12 and the secondary helical shaft 13 can be installed inside the housing 11 through the opening 10.

[0024] According to exemplary embodiments of this disclosure, reference is made to Figure 1 As shown, one end of the main screw shaft 12 is the feed end, and the other end is the discharge end. The pitch of the first spiral blade 121 on the main screw shaft 12 and the pitch of the second spiral blade 131 on the auxiliary screw shaft 13 are both variable pitch, and both are configured such that the pitch at the feed end is greater than the pitch at the discharge end. The variable pitch design enables the rapid conveying of large amounts of concrete at the feed end, while slowing down the conveying speed at the discharge end to ensure stable and uniform material output, further improving the uniformity of material distribution and avoiding local accumulation or insufficient material distribution.

[0025] According to exemplary embodiments of this disclosure, reference is made to Figure 1 and Figure 2 As shown, a concrete placement hopper 2 is provided near the discharge end of the housing 11. The concrete placement hopper 2 includes a first part 21 and a second part 22. The first part 21 is arranged vertically, and its top is connected to the housing 11. The second part 22 is located at the bottom of the first part 21. The second part 22 has a funnel-shaped structure. The vertical arrangement of the first part 21 facilitates the rapid arrival of concrete in the second part 22. The funnel-shaped second part 22 guides the concrete to fall smoothly, allowing the concrete to be delivered more concentratedly to the lower formwork 4 of the pole, thus improving the accuracy and efficiency of concrete placement.

[0026] According to exemplary embodiments of this disclosure, reference is made to Figure 1 and Figure 2 As shown, the material feeding structure of the pole feeding machine may also include a baffle assembly 3. Baffle assemblies 3 are provided on both opposite sides of the second part 22. Each baffle assembly 3 includes a baffle plate 31, which extends axially along the lower formwork 4 of the pole. The two baffle plates 31 are respectively used to block the corresponding sides above the lower formwork 4. The baffle plates 31 prevent concrete from overflowing from the sides of the lower formwork 4 during the feeding process, ensuring accurate concrete feeding within the lower formwork 4 and avoiding waste and pollution.

[0027] According to exemplary embodiments of this disclosure, reference is made to Figure 2 As shown, the baffle assembly 3 may also include an adjustment mechanism. The baffle plate 31 is slidably disposed on the second part 22. The adjustment mechanism is connected to the baffle plate 31 in a transmission manner, so that the baffle plate 31 can move closer to or further away from the lower mold 4 of the pole in the radial direction. The position of the baffle plate 31 can be flexibly adjusted according to the width of the lower mold 4 of different specifications of poles by means of the adjustment mechanism, thereby improving the versatility and adaptability of the fabric structure.

[0028] According to exemplary embodiments of this disclosure, reference is made to Figure 2 As shown, a parallel groove 221 can be formed on the inclined surface of the second part 22. The groove 221 extends from the top to the bottom of the second part 22. A slider 32 is provided on the baffle plate 31 to slide in cooperation with the groove 221. The adjustment mechanism includes a lead screw 33, which is rotatably disposed in the groove 221 and threadedly connected to the slider 32. With the above arrangement, the two lead screws 33 can be rotated to make the two baffle plates 31 slide along the groove 221, that is, to make the baffle plates 31 move along the inclined surface of the second part 22, so as to adjust the distance between the two baffle plates 31, thereby adapting to the width of the lower mold 4 of different specifications of electric poles. The operation is simple, stable and highly accurate, and can reliably realize the position adjustment of the baffle plates 31.

[0029] According to exemplary embodiments of this disclosure, reference is made to Figure 2 and Figure 3As shown, the baffle assembly 3 may further include a movable plate 34. Both the baffle plate 31 and the movable plate 34 are constructed with an arc-shaped structure, and the movable plate 34 has an arc-shaped through hole. The movable plate 34 is fitted onto the bottom of the baffle plate 31 through the arc-shaped through hole. The bottom surface of the movable plate 34 movably abuts against the upper surface of the lower die 4 of the pole. The lower part of the baffle plate 31 is threadedly connected to a limit post 35 to restrict the movement of the movable plate 34 in the vertical direction. The movable plate 34 can closely fit the upper surface of the lower die 4 of the pole, further enhancing the baffle effect. At the same time, the limit post 35 ensures that the movable plate 34 moves in a suitable position, preventing the movable plate 34 from detaching from the baffle plate 31 or moving excessively.

[0030] According to exemplary embodiments of this disclosure, reference is made to Figure 2 and Figure 3 As shown, the baffle assembly 3 may further include an elastic element 36. A stepped surface 310 is formed between the bottom and top of the baffle plate 31. The elastic element 36 is sleeved on the bottom of the baffle plate 31 and abuts against the movable plate 34 and the stepped surface 310. The elastic element 36 can be configured as a spring. The elastic element 36 enables the movable plate 34 to better adapt to the unevenness of the upper surface of the lower die 4 of the pole, ensuring that the movable plate 34 and the upper surface of the lower die 4 of the pole are always in close contact, thereby improving the reliability of the baffle.

[0031] In this disclosure, the length of the baffle plate 31 in the axial direction of the lower die 4 of the pole can be consistent with the length of the material hopper 2 in the axial direction of the lower die 4 of the pole, so as to fully cover the material feeding area and improve the material blocking effect.

[0032] Based on the above technical solutions, this disclosure also provides a pole feeding machine, including a frame 5, a feeding hopper 6 mounted on the frame 5, and a material distribution structure. The frame 5 has multiple wheels 7 at its bottom, and the material distribution structure is positioned below the feeding hopper 6. In the above technical solutions, the wheels 7 allow the pole feeding machine to move easily within the production site, improving feeding efficiency. The feeding hopper 6 stores concrete and, in conjunction with the material distribution structure, enables continuous feeding and distribution of concrete. The pole feeding machine of this disclosure possesses all the beneficial effects of the aforementioned material distribution structure, which will not be elaborated upon here.

[0033] Reference Figures 1 to 3 The usage method of the pole feeding machine disclosed herein is detailed below: First, the pole feeding machine is moved to the location of the lower mold 4 of the pole to be fed by the walking wheels 7; Next, according to the specifications of the lower mold 4 of the pole, the lead screw 33 is rotated, and the lead screw 33 drives the baffle plate 31 to slide in the slide groove 221. The position of the baffle plate 31 in the radial direction of the lower mold 4 of the pole is adjusted so that the baffle plate 31 is adapted to the side of the lower mold 4 of the pole. At the same time, under the action of the elastic element 36, the movable plate 34 is in close contact with the upper surface of the lower mold 4 of the pole. Next, concrete is injected into the feeding hopper 6. The concrete enters the housing 11 of the spiral feeding assembly 1 through the feeding hopper 6. The concrete enters the housing 11 from the feeding end. The corresponding driving component is activated to rotate the main spiral shaft 12 and the auxiliary spiral shaft 13. The first spiral blade 121 on the main spiral shaft 12 and the second spiral blade 131 on the auxiliary spiral shaft 13 mix and transport the concrete with different pitches and rotation directions. During the transport process, the lumps of concrete are broken up and the concrete is fully mixed. The concrete is transported to the feeding hopper 2 through the spiral feeding assembly 1. Under the guidance of the second part 22, the concrete falls smoothly into the lower formwork 4 of the pole, completing the feeding. After the fabric is laid, the upper and lower molds of the utility pole can be joined together, and then centrifugal molding can be performed to complete the production of the utility pole.
