Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of concrete preparation, and in particular to a steel fiber directional delivery device. Background Art

[0002] During the concrete preparation process, in order to improve the strength of concrete, steel fibers need to be added to the concrete and distributed evenly in the concrete.

[0003] The Chinese patent with the publication number CN218614755U discloses a steel fiber delivery device for the preparation of high-strength steel fiber concrete. In order to solve the problem of uniform distribution of steel fibers in concrete, the steel fibers are rotated and lifted by a drum with a gap on the surface and a material-beating rod inside. When the steel fibers are lifted to a certain height, they will fall and be broken up by the material-beating rod. The broken steel fibers will pass through the gap on the surface of the drum and fall onto the conveyor belt below the drum, and be transported to the concrete for uniform mixing. Although this steel fiber delivery device can avoid the problem of uneven mixing with concrete caused by concentrated stacking of steel fibers, since the device is when the steel fibers are rotated and lifted to a high place, the steel fibers fall onto the conveyor belt through the gap on the lower side of the drum under the action of gravity, and finally enter the mixing device through the conveyor belt. Since there are always steel fibers on the inner ring of the drum, it is difficult to ensure that the steel fibers accurately pass through the gap on the lower side of the drum during the falling process, and there is a defect that the delivery efficiency is not guaranteed.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] First, those skilled in the art should understand that these implementations are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0032] Secondly, it should be noted that in the description of the present application, terms such as "up", "down", "left", "right", "front", "back", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is merely for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present application.

[0033] In order to solve the above technical problems, Figure 1-4 The embodiment of the present application provides a steel fiber directional delivery device, including a drum 100, multiple groups of bearing members 200, multiple clamping members 300 and a conveyor belt 400; the drum 100 includes an inner drum 110 and an outer drum 120, and multiple installation cavities 140 are formed between the inner drum 110 and the outer drum 120, and the multiple installation cavities 140 are distributed in a ring-shaped interval around the central axis of the drum 100; the multiple groups of bearing members 200 are respectively installed in the multiple installation cavities 140, and the opening direction of the bearing members 200 is toward the central axis of the drum 100, which is used to carry the steel fibers located inside the inner drum 110; the multiple clamping members 300 are respectively inserted into the multiple installation cavities 140, and are engaged with the outer surfaces of the multiple groups of bearing members 200, so as to limit the bearing members 200; the conveyor belt 400 passes through the inner ring of the drum 100, and is used to receive the steel fibers dropped from the bearing members 200.

[0034] A group of carriers 200 refers to a plurality of carriers 200 spaced apart and distributed along the central axis of the drum 100 , and a plurality of carriers 200 constitute a group. In addition, the meanings of “group” in this embodiment are the same.

[0035] The above-mentioned steel fiber directional delivery device, when in use, dumps the steel fibers into the inner cylinder 110. Since multiple groups of carriers 200 are installed in the installation cavity 140, and the openings of the carriers 200 face the central axis of the drum 100, some of the steel fibers will fall into the carriers 200 during the rotation of the drum 100. When the drum 100 rotates, the steel fibers that have not fallen into the carriers 200 will slide back to the lowest position in the drum 100. The steel fibers that have entered the carriers 200 will slide from the carriers 200 to the conveyor belt 400 when the drum 100 rotates to a certain angle, and will be transported by the conveyor belt 400 to the mixing equipment for mixing with concrete. The steel fiber directional delivery device can always keep the amount of steel fibers delivered within a certain range during the delivery of the steel fibers, and will not cause the steel fibers to be stuck in the drum 100.

[0036] In a specific embodiment, a plurality of partitions 130 are disposed between the inner cylinder 110 and the outer cylinder 120 . The plurality of partitions 130 are distributed in an annular pattern around the central axis of the drum 100 , and an installation cavity 140 is formed between two adjacent partitions 130 and the inner cylinder 110 and the outer cylinder 120 .

[0037] Specifically, the partition 130 is disposed along the radial direction of the inner cylinder 110 and the outer cylinder 120 to support the inner cylinder 110 and the outer cylinder 120 .

[0038] In a specific embodiment, a plurality of groups of first positioning openings 111 are provided on the surface of the inner cylinder 110, and the plurality of groups of first positioning openings 111 are distributed in a ring-shaped manner around the central axis of the inner cylinder 110; a plurality of groups of second positioning openings 121 are provided on the surface of the outer cylinder 120, and the plurality of groups of second positioning openings 121 are distributed in a ring-shaped manner around the central axis of the outer cylinder 120, and the width of the second positioning openings 121 is greater than the width of the first positioning openings 111.

[0039] Specifically, since the width of the second positioning opening 121 is greater than the width of the first positioning opening 111 , the opening width of the bearing member 200 is greater than the bottom width, making it easier to carry the steel fiber and facilitate the steel fiber to detach from the bearing member 200 .

[0040] In a specific embodiment, the carrier 200 includes two side panels, two connecting plates 220, two curved plates 230 and a folding plate 240; the two side panels are arranged opposite to each other, the two connecting plates 220 are located in the upper half of the two side panels, and are respectively connected to the two side panels to form an opening of the carrier 200; the folding plate 240 is located in the lower half of the two side panels, and the two ends of the folding plate 240 are respectively connected to the two side panels, and the two curved plates 230 are respectively located between the other two ends of the two connecting plates 220 and the folding plate 240, and are connected to the connecting plates 220 and the folding plates 240.

[0041] Specifically, when the carrier 200 is installed in the installation cavity 140, the upper parts of the two side panels and the two connecting plates 220 are attached to the first positioning opening 111, and the lower parts of the two side panels and the folding plate 240 are attached to the second positioning opening 121. At this time, the clamp 300 is inserted into the installation cavity 140, and the edge of the clamp 300 is clamped on the arc plate 230, thereby completing the clamping and fixing of the carrier 200. By means of clamping and fixing, when the carrier 200 is used for a long time and is severely worn or damaged, it can be quickly replaced.

[0042] In a specific implementation, the arc opening of the arc plate 230 faces a direction away from the interior of the carrier 200 .

[0043] Specifically, the arc plate 230 is recessed into the interior of the carrier 200, so that when the steel fiber falls into the carrier 200, there is still a gap at the inner edge of the carrier 200, thereby preventing too much steel fiber from being blocked inside the carrier 200 and affecting the free fall of the steel fiber.

[0044] In a specific embodiment, the carrier 200 also includes a positioning frame 210, the lower surface of the positioning frame 210 is connected to the top ends of the two side plates and the top ends of the two connecting plates 220, and the lower surface of the positioning frame 210 is in contact with the inner surface of the inner tube 110; the outer edge of the upper surface of the positioning frame 210 is bent toward the lower surface of the positioning frame 210 and connected to the outer edge of the lower surface of the positioning frame 210.

[0045] Specifically, since the positioning frame 210 protrudes from the inner surface of the inner cylinder 110, the steel fibers that have not fallen into the supporting member 200 will remain on the inner surface of the inner cylinder 110, and when the drum 100 rotates to a certain angle, they will slide to the bottom of the drum 100 and randomly fall into each supporting member 200.

[0046] In a specific embodiment, the card member 300 includes a connecting head 310 and two card plates 320. The surfaces of the two card plates 320 are located in the same curved surface range, and there is a gap between the two card plates 320 for snap-fitting with the partition 130. The connecting head 310 is located at one end of the two card plates 320 and is connected to the two card plates 320.

[0047] Specifically, the gap between the two clamping plates 320 is used to clamp the partition 130, so that the clamping member 300 can only move along the radial direction of the drum 100. When the clamping plate 320 is clamped in the arc plate 230, the position of the clamping member 300 is fixed, and the carrier 200 can be clamped and fixed, which is convenient for disassembly and assembly.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
