[0002] Prefabricated cement piles for construction require the mixing of concrete into the pile mold. This process is called spreading, which has an important impact on the quality of the pile. Traditionally, a spreading vehicle is used to move concrete back and forth to put concrete into the pile mold. However, since concrete is non-solid, it is easy to overflow from the edge of the mold, especially for thick-walled piles. The concrete needs to be piled very high, and it is easy to overflow from the edge of the mold and fall to the ground. Therefore, most pile manufacturers now use a spreading hopper for spreading.

[0003] However, the existing distribution hopper structure is not reasonably designed, the concrete material is slow to be lowered into the cage, and the distribution needs to be repeated many times to complete, resulting in low production efficiency; in addition, the distribution effect is not ideal, the accumulated concrete material is easy to collapse or scatter, and the concrete at the upper end after distribution is loose, which is not conducive to mold closing and increases the difficulty of subsequent production processes.

[0023] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 and Figure 2As shown, the present embodiment provides an embodiment of a material distribution device for pipe pile distribution, comprising a material distribution hopper body 1, wherein a material receiving trough A and a material distribution trough B are sequentially arranged in the material distribution hopper body from top to bottom, wherein the material receiving trough A is open upwardly, and the material distribution trough B is communicated with the material receiving trough A and is open downwardly; wherein a scraper 11 and an extrusion plate 12 are arranged at the end of the material distribution hopper body 1, wherein the scraper 11 is relatively arranged on both sides of the material distribution trough B, and the scraper 11 is arranged outwardly; wherein the extrusion plate 12 is relatively arranged on both sides of the material receiving trough A, wherein the extrusion plate 12 comprises a first extrusion plate 121 and a second extrusion plate 122, wherein the first extrusion plate 121 is open to the material receiving trough A and the material distribution trough B, and the second extrusion plate 122 is connected to the top of the first extrusion plate 121, and the second extrusion plate 122 is open to the material receiving trough A.

[0025] In this embodiment, a receiving trough A and a distributing trough B which are interconnected are sequentially arranged from top to bottom in the distributing hopper body 1, and scrapers 11 located on both sides of the distributing trough B are arranged at both ends of the distributing hopper body 1. The scrapers 11 are arranged to be open outward. Since the concrete material distributed at the bottom will slightly collapse downward due to its own gravity, the distributed concrete material will generally be slightly wider than the distributing trough B. The scrapers 11 of this embodiment can gather and scrape the collapsed concrete material during the movement of the distributing hopper. Furthermore, the trough wall of the distributing trough B (i.e., the distributing hopper body 1 at the distributing trough B, i.e., the distributing pressing plate 1b hereinafter) smoothes the concrete material on the side. The scrapers 11 can prevent the distributing device from further scraping off the distributed material at the bottom during the back-and-forth operation. In addition, this embodiment In the embodiment, extrusion plates 12 located on both sides of the material receiving trough A are further provided at both ends of the distribution hopper body 1. During the operation of the distribution hopper, the concrete material entering the middle of the distribution trough B will be initially compacted by the second extrusion plate 122 and the concrete material above, and the concrete material pressed by the trough wall of the distribution trough B (that is, the distribution hopper body 1 at the distribution trough B, that is, the distribution pressing plate 1b below) will be further scraped, smoothed and compacted on the top concrete material under the action of the first extrusion plate 121. As a result, the concrete material below the distribution hopper body 1 is more compact, and its side and top surfaces are smoother and denser, and are not prone to looseness and collapse. The distribution quality is good and it is more convenient for mold closing operation. Due to the good density of the distribution material, it is equivalent to increasing the single distribution output, and the distribution efficiency is improved.

[0026] Specifically, the material distribution hopper body 1 of this embodiment includes two sets of material distribution plates arranged opposite to each other, and the material distribution plates include a material receiving baffle 1a and a material distribution pressing plate 1b. A material receiving trough A is formed between the material receiving baffles 1a of the two sets of material distribution plates, and a material distribution trough B is formed between the material distribution pressing plates 1b of the two sets of material distribution plates.

[0027] The scraper 11 and the extrusion plate 12 of this embodiment are preferably arranged at both ends of the material distribution hopper body 1. When the material distribution hopper body 1 reciprocates, the uniformity of the pipe pile distribution can be better guaranteed and the surface quality of the pipe pile can be improved.

[0028] The angle between the material distribution plate 1b and the horizontal direction in this embodiment is 55-68 degrees. The material distribution plate 1b set at this angle can ensure that the concrete material is not easy to collapse, and at the same time, can make full use of the space to distribute more materials to avoid excessive stacking.

[0029] In order to facilitate the production of pipe piles of different specifications and sizes, the spacing between the two groups of distribution plates in this embodiment can be adjusted.

[0030] Specifically, the cloth plate is provided with end baffles 13 at both ends of the material receiving slot A, and the end baffle 13 is provided with a first positioning assembly and a second positioning assembly on the side facing away from the material receiving slot A. The first positioning assembly includes a first positioning clamping plate 131 and a first positioning column 132, the first positioning clamping plate 131 is hinged to the end baffle 13, the first positioning column 132 is fixed to the end baffle 13, and the first positioning clamping plate 131 is provided with at least two first clamping grooves adapted to the first positioning column 132. The second positioning assembly is arranged below the first positioning assembly, and the second positioning assembly includes a second positioning column 133 and a second positioning clamping plate 134, the second positioning clamping plate 134 is hinged to the end baffle 13, the second positioning column 133 is fixed to the end baffle 13, and the second positioning clamping plate 134 is provided with at least two second clamping grooves adapted to the second positioning column 133. By engaging the first positioning column 132 with different first slots and engaging the second positioning column 133 with different second slots, the width adjustment of the material receiving slot A and the material distributing slot B can be quickly achieved.

[0031] Since the first positioning assembly and the second positioning assembly are provided on the end baffle 13 in this embodiment, the material distribution hopper body 1 can still maintain good stability after the size is adjusted, avoiding large shaking during the material distribution process, affecting the dimensional stability of the material receiving trough A and the material distribution trough B, and further affecting the material distribution effect.

[0032] To ensure that the widths of the material receiving trough A and the material distributing trough B can be adjusted smoothly, the first positioning clamp 131 and the second positioning clamp 134 of this embodiment are both set at a distance of more than 7 cm from the end baffle 13 to prevent the first positioning clamp 131 and the second positioning clamp 134 from being easily touched by the concrete material, resulting in the first positioning clamp 131 and the second positioning clamp 134 being fixed as the concrete material solidifies, affecting normal use.

[0033] In order to increase the speed of concrete material being put down the cage and further improve the material distribution efficiency, in this embodiment, when the pipe diameter of the produced pipe pile is ≤400mm, the top width of the material distribution trough B is adjusted to ≥130mm; when the pipe diameter of the produced pipe pile is >400mm, the top width of the material distribution trough B is adjusted to ≥180mm. The settings of the first clamping groove and the second clamping groove should meet the above width adjustment dimensions.

[0034] In order to facilitate the smooth operation of the material distribution hopper body 1 above the pipe pile mold, the material distribution device of this embodiment further includes a longitudinal slide bar 2 and a transverse slide bar 3. The end baffle 13 is provided with a transverse slide cylinder 135, and the transverse slide cylinder 135 is provided with a positioning bolt 136. The transverse slide bar 3 passes through the transverse slide cylinder 135, and the outer wall of the transverse slide bar 3 abuts against the end of the positioning bolt 136. The two ends of the transverse slide bar 3 are provided with longitudinal slide cylinders 31, and the longitudinal slide bar 2 is inserted into the longitudinal slide cylinder 31. By connecting the longitudinal slide bar 2 with the driving mechanism, the material distribution hopper body 1 can be made to run smoothly.

[0035] In order to further increase the speed of concrete material being lowered into the cage, a vibration motor 4 is provided on the outer wall of the distribution hopper body 1 in this embodiment. By adjusting the amplitude and vibration frequency through the frequency converter, the distribution efficiency of concrete material with poor fluidity and the distribution efficiency of the pile head (densified area) can be improved.

[0036] In this embodiment, a reinforcing rib 14 is arranged outside the material receiving trough A and the material distributing trough B, and the reinforcing rib 14 is fixed to the material receiving baffle 1a and the material distributing pressing plate 1b. The reinforcing rib 14 further ensures the structural and dimensional stability of the material distributing hopper body 1.

[0037] To ensure smooth material discharge, the extruded plate 12 of the present embodiment further includes a top baffle 123 and an inner baffle 124, wherein the first extruded plate 121, the second extruded plate 122 and the top baffle 123 are respectively connected to the inner baffle 124, and the first extruded plate 121, the second extruded plate 122, the top baffle 123 and the material receiving baffle 1a are sequentially enclosed and form a closed chamber with the inner baffle 124 and the end baffle 13. This can prevent the concrete material from being stuck between the first extruded plate 121, the second extruded plate 122 and the material receiving baffle 1a, causing material waste and increasing the difficulty of cleaning.

[0038] In summary, the implementation of the present invention has the following beneficial effects:

[0039] 1. The scraper 11 opened outward can gather and scrape the collapsed concrete materials during the movement of the material placing hopper, so as to prevent the material placing plate 1b from further scraping off the materials placed at the bottom;

[0040] 2. The second extrusion plate 122 in the extrusion plate 12 and the concrete material above can initially compact the concrete material entering the middle of the distribution trough B during the movement of the distribution hopper. The first extrusion plate 121 can further scrape, smooth and compact the top of the concrete material pressed by the distribution pressing plate 1b. As a result, the concrete material below the distribution hopper body 1 is more compact, and its side and top surfaces are smoother and denser, and are not prone to looseness or collapse, and the distribution quality is good.

[0041] 3. Due to the good density of the fabric, the output of a single fabric is increased, and the fabric efficiency is improved;

[0042] 4. The width of the receiving trough A and the distributing trough B can be conveniently adjusted through the first positioning assembly and the second positioning assembly, and can adapt to the production of pipe piles of various specifications and sizes;

[0043] 5. The adjusted material distribution hopper body 1 has good structural stability and is not easy to shake during the material distribution process, which will affect the material distribution effect;

[0044] 6. The first positioning card plate 131 and the second positioning card plate 134 are set at a distance of more than 7 cm from the end baffle 13, which is conducive to preventing the first positioning card plate 131 and the second positioning card plate 134 from being contaminated by concrete materials and affecting normal use.

[0045] 7. The setting of the vibration motor 4 can help improve the distribution efficiency of concrete materials with poor fluidity.

[0046] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
