Description

Technical Field

[0001] This invention relates to the field of construction equipment processing technology, specifically to a double-discharge material silo and its layout and manufacturing method. Background Technology

[0002] Batching silos are a common equipment structure in engineering practice. They have a large inlet at the top, a small outlet at the bottom, and a conical or near-conical irregular shape in the middle. The outer walls of these batching silos are mostly made of steel plates. However, because of their irregular shape and large diameter and height, the layout is difficult and the accuracy is not high during manufacturing. This can easily lead to the centerline of the finished product not meeting the design and usage requirements. Summary of the Invention

[0003] This invention is made to solve the above-mentioned technical problems. Its purpose is to provide a double-outlet batching bin and its layout and manufacturing method, which can accurately lay out the bin wall of the double-outlet batching bin, making it convenient to process and manufacture the double-outlet batching bin.

[0004] To achieve the above objectives, in a first aspect, the present invention provides a double-outlet feeding bin, comprising: a bin body, which is a cylindrical structure with openings at both ends; two hoppers, symmetrically arranged at the lower end of the bin body, the upper end of which is a semicircle with the same diameter as the bin body, the lower end of which is a circle, the side walls of the two hoppers facing each other being isosceles triangles, and the side walls of the two hoppers facing away from each other being arc-shaped side walls.

[0005] To achieve the above objectives, in a second aspect, the present invention provides a layout method for creating a layout diagram of the double-outlet batching silo as described above, comprising the following steps:

[0006] S11. Draw the unfolded diagram of the warehouse body, denoted as the first lofting diagram, with a length L1 = 2πr1 and a width W1 = h1, where h1 is the height of the warehouse body and r1 is the radius of the warehouse body;

[0007] S12. Draw the isosceles triangular sidewall of the hopper, denoted as the second lofting diagram. The base length L2 = 2r1 and the height of the second lofting diagram are... Where d1 is the distance between the lower end faces of the two hoppers, and h2 is the height of the hopper;

[0008] S13. In 3D modeling software, draw a semicircular ring and a circular ring that are parallel to each other vertically. The distance between the projections of the centers of the semicircular rings and the circular rings onto the horizontal plane is... The vertical distance between the semicircular ring and the circular ring is h2, where r2 is the radius of the lower port of the hopper. n first connection points are equidistantly arranged on the semicircular ring, and n first connection points are equidistantly arranged on the side of the circular ring closest to the semicircular ring, and these first connection points are sequentially connected to form n first connection lines. 2m second connection points are equidistantly arranged on the other side of the circular ring, and the m second connection points on the left and right sides are respectively connected to the two endpoints of the semicircular ring to form 2m second connection lines. A plate is fabricated between the semicircular ring, the circular ring, the first connection lines, and the second connection lines, and unfolded onto a plane, which is the unfolded view of the arc-shaped sidewall of the hopper, denoted as the third layout view.

[0009] To achieve the above objectives, in a third aspect, the present invention provides a method for manufacturing a double-discharge-port batching silo, which employs the layout method described above and includes the following steps:

[0010] S21. Make a rectangular flat plate according to the first layout drawing, and roll it into a cylindrical silo body;

[0011] S22. Construct two isosceles triangular plates according to the second layout drawing;

[0012] S23. Make two irregularly shaped flat plates according to the third layout drawing, and roll them into structures with a semi-circular top and a circular bottom. Then, weld their two sides to the two sides of the isosceles triangular flat plate to form two hoppers. Then, symmetrically weld the tops of the two hoppers to the bottom of the silo body.

[0013] Based on the above description and practice, it is clear that the double-outlet batching hopper of this invention can evenly discharge materials from two outlets respectively, and the opposing sidewalls of the two hoppers are inclined isosceles triangles. Compared with conical hoppers, the two hoppers have a larger space between them, which facilitates construction operations. The layout method of this invention divides the batching hopper into three parts for layout: the hopper wall, the arc-shaped sidewall of the hopper, and the triangular sidewall of the hopper. The layout process is then completed through positioning and unfolding to form the layout diagram of each part. Finally, the manufacturing method of the double-outlet batching hopper of this invention, using the above-mentioned layout diagram, can accurately dispense materials and complete the construction of the double-outlet batching hopper.

[0025] This embodiment discloses a dual-discharge feed silo, its layout method, and its manufacturing method. Figure 1 The three-dimensional structure of the dual-outlet feeding hopper is shown. Figure 2 The front structure of the dual-outlet batching hopper is shown. Figure 3 It shows Figure 2 The structure of section AA in the middle, Figure 4 It shows Figure 2 The structure of the middle BB section, Figure 5 The three-dimensional structure of the hopper in the dual-outlet feeding bin is shown. Figure 6 The planar unfolded structure of the hopper in the dual-outlet feeding bin is shown.

[0026] Please refer to Figures 1 to 6 The dual-outlet batching silo consists of a silo body 1 and two hoppers 2, arranged from top to bottom. The silo body 1 is a cylindrical structure open at both ends, with the upper end being the inlet and the lower end being the outlet, connected to the two hoppers 2, allowing material to be discharged separately through each hopper. The two hoppers 2 are symmetrically positioned at the lower end of the silo body 1, with their upper ends being semi-circular and having the same diameter as the silo body 1, and their lower ends being circular. The facing sidewalls of the two hoppers 2 are isosceles triangles, while the opposing sidewalls are arc-shaped. This type of batching silo structure allows material to be discharged evenly from both outlets. Furthermore, the inclined isosceles triangles of the facing sidewalls of the two hoppers 2 provide a larger space between them compared to conical hoppers 2, facilitating construction operations.

[0027] Specifically, the radius of the hopper 1 is r1, the radius of the lower end of the hopper 2 is r2, and the distance between the lower end faces of the two hoppers 2 is d1. With this structure, the center lines of the two hoppers 2 are relatively close to the center of the upper port. This allows for a larger distance between the two hoppers 2 while still achieving a better material discharge effect and reducing the likelihood of material blockage.

[0028] Furthermore, in this embodiment, the radius of the silo 1 is r1 = 360cm, the radius of the lower port of the hopper 2 is r2 = 75cm, and the distance between the lower ports of the two hoppers 2 is d1 = 150cm, which can meet the material preparation needs of most construction sites.

[0029] For this type of batching silo structure, accurate layout, especially of the silo wall, is difficult to achieve during the design and manufacturing process. Therefore, this embodiment also discloses a layout method for accurately creating the layout diagram of the aforementioned double-outlet batching silo. In this layout method, the batching silo is divided into three parts for layout: the silo wall of the silo body 1, the arc-shaped side wall of the hopper 2, and the triangular side wall of the hopper 2. Accordingly, the layout method mainly includes the following three steps:

[0030] Step S11: First, draw the unfolded view of the warehouse body 1, and denot it as the first lofting view.

[0031] Specifically, since the silo 1 is a cylindrical structure, it unfolds into a rectangular structure. Therefore, drawing a rectangle with length L1 and width W1 is the first lofting diagram of the silo 1. Wherein, length L1 = 2πr1, width W1 = h1, h1 is the height of the silo 1, and r1 is the radius of the silo 1.

[0032] Step S12: Draw the shape of the isosceles triangular sidewall of hopper 2, and record it as the second layout drawing.

[0033] The isosceles triangle has a base length of L2 and a height of h3, where the length L2 is the same as the diameter of the silo 1, i.e., L2 = 2r1.

[0034] high Where d1 is the distance between the lower ends of the two hoppers 2, which can be set according to actual needs, and h2 is the height of the hopper 2.

[0035] Step S13: Draw the unfolded shape of the arc-shaped sidewall of hopper 2, and denot it as the third layout drawing.

[0036] First, in the 3D modeling software, draw a semi-circular ring and a circular ring that are parallel to each other, corresponding to the upper and lower ports of hopper 2, respectively. The distance between the projections of the centers of the semi-circular rings and the circular rings onto the horizontal plane is specified. The vertical distance between the semicircular ring and the circular ring is h2, where r2 is the radius of the lower port of hopper 2. This 3D model can be created using software such as BIM, SolidWorks, ProE, or Creo. This step allows for the positioning of the upper and lower ports of hopper 2.

[0037] Next, n first connection points are equidistantly set on the semicircular ring, and n first connection points are also equidistantly set on the side of the ring closest to the semicircular ring. These first connection points are then connected sequentially from top to bottom to form n first connection lines 3. See details... Figure 5 Each of the first connecting lines 3 forms a closed frame with the upper and lower semicircular rings and circular rings, and n plates can be created using software.

[0038] Then, two second connection points are equidistantly arranged at 2m intervals on the other side of the ring. These m second connection points on both the left and right sides are then connected to the endpoints of the semicircular ring on that side, forming 2m second connection lines 4. (See details...) Figure 5 Each of the second connecting lines 4 forms a closed frame with the upper and lower semicircular rings and circular rings, and 2m plates can be created using software.

[0039] Finally, the software sequentially unfolds each plate into a plane, which is the unfolded shape of the arc-shaped sidewall of hopper 2. See details. Figure 6 .

[0040] In step S13, n≥8 and m≥4. The larger the values ​​of these two values, the higher the accuracy of the layout. In this embodiment, n=10 and m=5, resulting in the following layout: Figure 6 The lofting diagram shown.

[0041] The three layout drawings described above can be dimensioned according to actual needs to facilitate subsequent material preparation by the operators. Using this method, the layout drawings for the double-outlet material feeding silo can be accurately produced, enabling precise material preparation by the operators.

[0042] In this embodiment, a method for manufacturing a double-discharge-port batching silo is also disclosed, which adopts the above-mentioned layout method and specifically includes the following steps:

[0043] Step S21: According to the first layout drawing, cut and cut the raw steel plate to make a rectangular flat plate, and roll it into a cylindrical silo body 1.

[0044] Step S22: According to the second layout drawing, cut and cut two isosceles triangular flat plates from the original steel plate.

[0045] Step S23: According to the third layout drawing, cut two irregularly shaped flat plates from the raw steel plate and roll them into a structure with a semi-circular upper end and a circular lower end. Then, weld the two sides of the flat plates to the two sides of the isosceles triangular flat plates to form two hoppers 2. Then, symmetrically weld the upper ends of the two hoppers 2 to the lower end of the silo body 1. At this time, the lower end of the silo body 1 is completely connected to the two hoppers 2.

[0046] Finally, the base edges of the two isosceles triangular plates can be welded together to ensure that the material in the silo 1 can only be discharged through the two hoppers 2.

[0047] The double-outlet batching bin produced by this method has a center line of both the bin body 1 and the two hoppers 2 that are vertical lines, which can meet the design and usage requirements.

[0048] The invention is not limited to the details of the exemplary embodiments described above, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
