However, when the short steel fibers fall horizontally onto the mesh screen, they are difficult to pass through the holes, and even with vibration, it takes time to randomly adjust, resulting in blockage and affecting the feeding speed of the short steel fibers. Summary of the Utility Model

[0021] In the description of the present utility model, it should also be noted that unless otherwise clearly specified and defined, if the terms "set", "installed", "connected", and "linked" are used, they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0022] The following will Figures 1 to 4 describe the present utility model in detail.

[0023] A feeding device for mixing steel fiber concrete includes a main body 1. A feeding hopper 101 is provided at the top of the main body 1. A vibrating screen 2 is provided inside the main body 1 near the top. Sliding inclined surfaces 201 are provided on both sides of the vibrating screen 2. A displacement groove 2011 is provided at the top of the sliding inclined surface 201. A deflection rod 202 is connected to the top of the sliding inclined surface 201 through the displacement groove 2011. An expansion component is provided at the top of the deflection rod 202. The expansion component swings and displaces along the displacement groove 2011. Both sides of the vibrating screen 2 are inclined and extended by the sliding inclined surfaces 201.

[0024] First, short steel fibers are poured into the main body 1 through the feeding hopper 101 to fully stir and mix them with cement and other mixtures, so that the short steel fibers are randomly distributed in the cement. When the short steel fibers fall into the main body 1 and are mixed with the cement, they will first pass through the uniform sieving of the vibrating screen 2, so that the short steel fibers can be evenly distributed and fall into the cement for stirring, avoiding the entanglement of the short steel fibers in lumps and making it inconvenient to fully stir and mix.

[0025] When the short steel fibers fall onto the vibrating screen 2 for screening and falling, the short steel fibers will slide along the sliding inclined surfaces 201 on both sides of the vibrating screen 2. During the sliding process, they will fall through the holes above. Through the sliding along the sliding inclined surfaces 201, the short steel fibers falling on the vibrating screen 2 will not accumulate together and will be evenly screened and fallen through the sliding of the inclined surface, making the screening and falling more uniform.

[0026] Further, two deflection rods 202 are provided in a group and are inclined in a "V" shape. The deflection rod 202 further includes a pulley 2021. The pulley 2021 is connected to one side of the deflection rod 202. One side of the pulley 2021 protrudes from the opposite side of the two deflection rods 202. The expansion assembly includes a deflection shaft 2022 and a limiting block 2023. The deflection shaft 2022 is connected to one end of the deflection rod 202. The limiting block 2023 is connected to the end of the deflection shaft 2022 away from the deflection rod 202. The deflection rod 202 is connected to the displacement groove 2011 through the deflection shaft 2022 at one end. Tooth marks meshing with the rack on the top inner wall of the displacement groove 2011 are provided on the side wall of the deflection rod 202. The limiting block 2023 is a direction block matching the displacement groove 2011. One end of the deflection shaft 2022 is connected to the groove of the torsion spring on one side of the limiting block 2023 through a protruding round shaft.

[0027] At the same time, when the short steel fibers slide down along the sliding inclined plane 201, they will pass through the deflection rod 202. By contacting the inclined deflection rod 202, the laterally sliding short steel fibers can be deflected by a certain angle along the inclined plane of the deflection rod 202 for sliding, so that they slide vertically and can better fall through the holes. At the same time, a pulley 2021 is provided protruding from the opposite side of the deflection rod 202. The rolling of the pulley 2021 reduces the friction of the short steel fibers during sliding, enables them to slide more smoothly, and better deflects the short steel fibers.

[0028] Finally, if the short steel fibers do not deflect in time when laterally sliding between the two deflection rods 202 and cause blockage, they will intercept the subsequent short steel fibers, resulting in an increase in weight and extrusion. As a result, they will exert a certain pressure on the two side deflection rods 202, causing the deflection rod 202 to deflect through the deflection shaft 2022 at one end, thereby expanding the distance between the two deflection rods 202 to allow the short steel fibers to slide down. At the same time, when the deflection shaft 2022 rotates, due to meshing with the rack on the top inner wall of the displacement groove 2011, the deflection shaft 2022 will displace along the displacement groove 2011, so that the overall distance between the two deflection rods 202 will also increase to allow the blocked short steel fibers to slide. At the same time, the deflection shaft 2022 will be connected with a limiting block 2023 in the displacement groove 2011. Due to the direction setting of the limiting block 2023, it cannot be driven to rotate and will only displace along with the deflection shaft 2022. Then, through the torsion spring connection between the limiting block 2023 and the deflection shaft 2022, the deflection shaft 2022 can perform a reset rotation and displacement.

[0029] The following is the specific implementation process of the present utility model. First, short steel fibers are poured into the main body 1 through the feeding hopper 101 to fully stir and mix them with cement and other mixtures, so that the short steel fibers are randomly distributed in the cement. When the short steel fibers fall into the main body 1 and are mixed with the cement, they will first pass through the uniform sieving of the vibrating screen 2, so that the short steel fibers can be evenly distributed and fall into the cement for stirring, avoiding the short steel fibers from agglomerating and entangling together, which is inconvenient for full stirring and mixing. When the short steel fibers fall onto the vibrating screen 2 for screening and falling, the short steel fibers will slide along the sliding slopes 201 on both sides of the vibrating screen 2. During the sliding process, they will fall through the holes above. Through the sliding along the sliding slopes 201, the short steel fibers falling on the vibrating screen 2 will not accumulate together, but will be evenly screened down through the sliding of the slopes, making the screening and falling more uniform. At the same time, when the short steel fibers slide along the sliding slopes 201, they will pass through the deflecting rods 202. By contacting the inclined deflecting rods 202, the horizontally sliding short steel fibers can be deflected by an angle along the slopes of the deflecting rods 202 and slide vertically, so that they can better fall through the holes. At the same time, on the opposite side of the deflecting rod 202, there is a protruding part provided with a pulley 2021. By the rolling of the pulley 2021, the friction of the short steel fibers during sliding can be reduced, enabling them to slide more smoothly and better deflect the short steel fibers. Finally, if the short steel fibers do not deflect in time when horizontally sliding between the two deflecting rods 202 and cause blockage, due to intercepting the subsequent short steel fibers, the weight will increase and cause extrusion, so that a certain pressure will be exerted on the two deflecting rods 202 on both sides, causing the deflecting rods 202 to deflect through the pivot shafts 2022 at one end, thereby expanding the distance between the two deflecting rods 202 to allow the short steel fibers to slide down. At the same time, when the pivot shafts 2022 rotate, due to the meshing with the rack at the top inner wall of the displacement groove 2011, the pivot shafts 2022 will displace along the displacement groove 2011, so that the overall distance between the two deflecting rods 202 will also expand to allow the blocked short steel fibers to slide. At the same time, the pivot shafts 2022 are connected with limiting blocks 2023 in the displacement grooves 2011. Due to the direction setting of the limiting blocks 2023, they cannot be driven to rotate, but only follow the pivot shafts 2022 to displace. Then, through the torsion spring connection between the limiting blocks 2023 and the pivot shafts 2022, the pivot shafts 2022 can be reset and rotated and displaced.

For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
