[0058] Beneficial effects of the present invention:

[0059] 1. This type of steel bar feeding machine for construction projects is equipped with a material leveling component and a grinding component. The driving wheel rotates to drive the rotating sleeve and the grinding sandpaper on its inner wall to grind the outer wall of the steel bar, thereby achieving efficient removal of rust on the surface of the steel bar.

[0060] 2. This type of steel bar feeding machine for construction projects is equipped with a synchronous belt and a chip shaking assembly. During the grinding process, the paddle on the synchronous belt strikes the steel bar through mechanisms such as connecting rods, rotating shafts and striking rods, effectively shaking off the grinding debris adhering to the steel bar. This method of striking and shaking off the chips not only improves the cleanliness of the steel bar surface, but also avoids the influence of the debris on the subsequent anti-rust treatment, ensuring that the anti-rust oil can be evenly applied.

[0061] 3. This type of steel bar feeding machine for construction projects, by setting up a coating wheel and an oiling assembly, realizes uniform coating of anti-rust grease through the rotation of the coating wheel, in coordination with the oil bag, oil suction pipe, oil supply pipe, one-way valve and other components in the oiling assembly. During the rotation of the coating wheel, the anti-rust grease in the oil storage tank can be evenly added to its outer wall, and coated on the surface of the steel bar through contact with the steel bar. This design not only improves the coating efficiency, but also ensures the uniform distribution of the anti-rust grease, thereby enhancing the anti-rust performance of the steel bar and extending its service life.

[0075] like Figures 1 to 8As shown, a steel bar feeding machine for construction engineering comprises a bottom plate 1 and a support plate 2, the support plate 2 is fixedly mounted at a corner of the top surface of the bottom plate 1, a push rail 3 is fixedly mounted on the top surface of the support plate 2, an electric push rod 4 is fixedly mounted on the end of the push rail 3, and also comprises: a fixed plate 5, fixedly mounted on the top surface of the bottom plate 1 and located on the side of the push rail 3 away from the electric push rod 4; two driving wheels 6, rotatably mounted on the side of the fixed plate 5; a driving motor 7, fixedly mounted on the side of the fixed plate 5, and the output end of the driving motor 7 is fixedly connected to one of the two driving wheels 6; a material leveling component, arranged on the top surface of the bottom plate 1, for evenly spreading the steel bars for convenient feeding; a bracket 9, fixedly mounted On the top surface of the bottom plate 1, close to the side of the fixed plate 1 5; a grinding component, arranged on the bracket 9, used for grinding and removing rust from the steel bars; a fixed plate 11, fixedly mounted on the top surface of the bottom plate 1; two smearing wheels 12, rotatably mounted on the side of the fixed plate 11; two sets of oiling components, respectively arranged on the side of the two smearing wheels 12, used for injecting oil into the outer wall of the smearing wheels 12; an oil storage tank 14, fixedly mounted on the top surface of the bottom plate 1; two pulleys 15, respectively arranged at the output end of the drive motor 7 and the side of the smearing wheel 12; a synchronous belt 16, mounted on the two pulleys 15; a chip shaking component, arranged between the bracket 9 and the fixed plate 11, used for shaking off the chips from the grinding of the steel bar surface;

[0076] When in use, the steel bars can be hoisted onto the material-leveling assembly on the base plate 1. Under the action of the material-leveling assembly, the steel bars can be arranged one by one and enter the advancement rail 3. When the electric push rod 4 is turned on, the steel bars in the advancement rail 3 can be pushed between the two driving wheels 6. At this time, the driving motor 7 is turned on to drive the driving wheel 6 to rotate to transport the steel bars, so that the steel bars pass through the grinding assembly, the chip shaking assembly and the two smearing wheels 12 in sequence. When the driving wheel 6 is driven and rotated by the driving motor 7, the material-leveling assembly can be driven. When the steel bars pass through the grinding assembly, the rust on the surface of the steel bars can be polished and removed. When passing through the chip shaking assembly again, the debris generated by the grinding can be shaken off to avoid affecting subsequent use. When the steel bars pass through the two smearing wheels 12, the smearing wheel 12 can rotate with the driving wheel 6 under the cooperation of the pulley 15 and the synchronous belt 16, and during the rotation, the anti-rust grease in the oil storage tank 14 can be added to the smearing wheel 12 through the oiling assembly. The anti-rust grease can be evenly applied to the surface of the steel bars through the rotation of the smearing wheel 12, thereby completing the rust removal during the steel bar feeding process.

[0077] like Figure 1 , Figure 2 , Figure 3As shown, the material distribution assembly includes: a transmission shaft 81, fixedly mounted on the side of a driving wheel 6 connected to the driving motor 7; a mounting plate 82, fixedly mounted on the top surface of the bottom plate 1; a linkage wheel 83, rotatably mounted on the side of the mounting plate 82, and the end of the transmission shaft 81 is fixedly connected to the side of the linkage wheel 83; a plurality of protrusions 84, distributed in an annular array and fixedly mounted on the outer wall of the linkage wheel 83; four spring support rods 85, fixedly mounted on the top surface of the bottom plate 1; a blanking plate 86, fixedly mounted on the telescopic ends of the four spring support rods 85, a limiting frame 88 is arranged on the top surface of the blanking plate 86, and one end of the blanking plate 86 is connected to the advancing rail 3; a reinforcing rib 87, fixedly mounted on the bottom surface of the blanking plate 86, and the reinforcing rib 87 is L-shaped, and the reinforcing rib 87 is adapted to the protrusion 84;

[0078] After the steel bars are hoisted onto the blanking plate 86, the driving motor 7 is turned on to drive the driving wheel 6 to rotate. When the driving wheel 6 rotates, it can synchronously drive the transmission shaft 81 and the interlocking wheel 83 to rotate. When the interlocking wheel 83 rotates, the convex block 84 thereon can reciprocate the reinforcing rib 87, so that the reinforcing rib 87 drives the blanking plate 86 to reciprocate in the vertical direction through the spring support rod 85, thereby vibrating the blanking plate 86, so that the steel bars on the blanking plate 86 can be evenly arranged in the limit frame 88 on the blanking plate 86 under the action of vibration, and can enter the propulsion rail 3 to achieve propulsion.

[0079] like Figure 4 As shown, the grinding assembly includes: a rotating sleeve 101, which is rotatably mounted on the top of the bracket 9, and the rotating sleeve 101 is coaxially arranged with the advancing rail 3; a grinding sandpaper 102, which is arranged on the inner wall of the rotating sleeve 101; a driven bevel gear 103, which is fixedly sleeved on one end of the rotating sleeve 101; a support rod 104, which is fixedly mounted on the top surface of the bottom plate 1; a driving bevel gear 105, which is rotatably mounted on the top of the support rod 104, and the driving bevel gear 105 is meshed with the driven bevel gear 103, and the driving bevel gear 105 is connected to the driving wheel 6 through the driven wheel and the synchronous belt transmission;

[0080] When the driving wheel 6 rotates, the driving bevel gear 105 can be driven to rotate through the driven wheel and the synchronous belt. The driving bevel gear 105 is meshed with the driven bevel gear 103, and then the driven bevel gear 103 and the rotating sleeve 101 can be driven to rotate. When the rotating sleeve 101 rotates, the outer wall of the steel bar can be polished through the grinding sandpaper 102 on the inner wall to achieve the purpose of rust removal.

[0081] like Figure 5 , Figure 6As shown, the oiling assembly includes: a fixed shell 131, which is fixedly mounted on the top surface of the bottom plate 1 through the top plate and is located at the end position of the smear wheel 12; a driving rod 132, which is fixedly mounted on the side of the smear wheel 12, and the end of the driving rod 132 passes through the fixed shell 131; a driving block 133, which is fixedly sleeved on the end of the driving rod 132 located on the inner side of the fixed shell 131; an extrusion block 134, which is arranged on the inner wall of the fixed shell 131, and the side opposite to the driving block 133 and the extrusion block 134 is arranged as a corresponding inclined surface; two guide grooves 135, which are symmetrically opened on the inner wall of the fixed shell 131; two guide blocks 136, which are symmetrically fixedly mounted on the outer wall of the extrusion block 134 , and the guide block 136 is slidably connected with the guide groove 135; the oil capsule 137 is arranged on the inner side of the fixed shell 131, and the two ends of the oil capsule 137 are respectively fixedly connected with the inner wall of the fixed shell 131 and the side of the extrusion block 134; the oil suction pipe 138 is arranged between the oil capsule 137 and the oil storage tank 14, and the two ends of the oil suction pipe 138 are respectively connected with the oil capsule 137 and the oil storage tank 14; the oil supply pipe 139 is arranged at the symmetrical position of the oil capsule 137 and the oil suction pipe 138, and the end of the oil supply pipe 139 away from the oil capsule 137 extends to the outer wall of the coating wheel 12, and the inner walls of the oil suction pipe 138 and the oil supply pipe 139 are installed with one-way valves with opposite flow directions;

[0082] When the smear wheel 12 rotates, it can synchronously drive the driving rod 132 to rotate. When the driving rod 132 rotates, it can drive the driving block 133 to rotate. The side opposite to the driving block 133 and the extrusion block 134 is set to a corresponding inclined surface. Therefore, when the driving block 133 rotates, under the action of the inclined surface, the extrusion block 134 can slide back and forth on the inner wall of the fixed shell 131 through the guide groove 135 and the guide block 136, thereby squeezing and stretching the oil bag 137. Since the oil suction pipe 138 and the oil supply pipe 139 are equipped with a one-way valve with opposite flow directions, when the oil bag 137 is stretched, the anti-rust oil in the oil storage tank 14 can be drawn into the oil bag 137 through the oil suction pipe 138, and when the oil bag 137 is squeezed, the internal anti-rust oil can be added to the outer wall of the smear wheel 12 through the oil supply pipe 139. When the steel bar passes through the two smear wheels 12, the two smear wheels 12 rotate to evenly apply the anti-rust oil to the outer wall of the steel bar, ensuring that the steel bar is more durable when used after the unloading is completed.

[0083] like Figure 7 , Figure 8As shown, the chip shaking assembly includes: a connecting frame 171, fixedly mounted on the top surface of the bottom plate 1 between the bracket 9 and the fixing plate 11; a rotating shaft 172, rotatably mounted on the top of the connecting frame 171; a plurality of striking rods 173, distributed in a linear array and fixedly sleeved on the outer wall of the rotating shaft 172; a torsion spring 174, sleeved on the end of the rotating shaft 172; a plurality of striking heads 175, respectively fixedly mounted on the top ends of the plurality of striking rods 173; a plurality of connecting rods 176, respectively fixedly mounted on the bottom ends of the plurality of striking rods 173; a plurality of paddles 177, distributed at equal intervals and fixedly mounted on the outer wall of the synchronous belt 16, and the paddles 177 are inclined and correspond to the connecting rods 176;

[0084] When the driving wheel 6 drives the coating wheel 12 to rotate through the pulley 15 and the synchronous belt 16, it can synchronously drive the paddle 177 on the synchronous belt 16 to move. The paddle 177 is in an inclined state and is evenly spaced. When the paddle 177 moves and contacts the connecting rod 176, it can drive the connecting rod 176, the rotating shaft 172 and the striking rod 173 to rotate under the action of the inclination. When the gap between the connecting rod 176 and the two paddles 177 is separated from the paddles 177, the rotating shaft 172, the striking rod 173 and the striking head 175 can be reversed under the action of the torsion spring 174, thereby achieving the striking of the steel bars, so that the grinding debris adhering to the steel bars can be shaken off, so as to facilitate the subsequent application of the anti-rust oil.

[0085] The technical solution provided by the present invention can be used to hoist the steel bars to the material-leveling assembly on the bottom plate 1. Under the action of the material-leveling assembly, the steel bars can be arranged one by one and enter the advancing rail 3. When the electric push rod 4 is turned on, the steel bars in the advancing rail 3 can be pushed between the two driving wheels 6. At this time, the driving motor 7 is turned on to drive the driving wheel 6 to rotate to transport the steel bars, so that the steel bars pass through the grinding assembly, the chip-shaking assembly and the two smearing wheels 12 in turn. When the driving wheel 6 is driven by the driving motor 7 to rotate, the material-leveling assembly can be driven, and when the steel bars pass through the grinding assembly, the surface of the steel bars The rust can be removed by grinding, and when passing through the chip shaking assembly, the debris generated by grinding can be shaken off to avoid affecting the subsequent use. Then, when the steel bar passes through the two coating wheels 12, the coating wheel 12 can rotate with the driving wheel 6 under the cooperation of the pulley 15 and the synchronous belt 16, and the anti-rust grease in the oil storage tank 14 can be added to the coating wheel 12 during the rotation process through the oiling assembly. The anti-rust grease can be evenly applied to the surface of the steel bar through the rotation of the coating wheel 12, and the rust removal in the steel bar feeding process can be completed. Then the steel bar can be cut and other treatments are completed.

[0086] Specifically, after the steel bar is hoisted onto the blanking plate 86, the driving motor 7 is turned on to drive the driving wheel 6 to rotate. When the driving wheel 6 rotates, it can synchronously drive the transmission shaft 81 and the linkage wheel 83 to rotate. When the linkage wheel 83 rotates, the convex block 84 thereon can reciprocate the reinforcing rib 87, so that the reinforcing rib 87 drives the blanking plate 86 to reciprocate in the vertical direction through the spring support rod 85, thereby achieving vibration of the blanking plate 86, so that the steel bars on the blanking plate 86 can be evenly arranged in the limit frame 88 on the blanking plate 86 under the action of vibration, and can enter the propulsion rail 3 to achieve propulsion; when the driving wheel 6 rotates, it can drive the driving bevel gear 105 to rotate through the driven wheel and the synchronous belt, and the driving bevel gear 105 is meshed with the driven bevel gear 103, and then the driven bevel gear 103 and the rotating sleeve 101 can be driven to rotate. When the rotating sleeve 101 rotates, the outer wall of the steel bar can be polished through the grinding sandpaper 102 on the inner wall to achieve the purpose of rust removal;

[0087] When the driving wheel 6 drives the coating wheel 12 to rotate through the pulley 15 and the synchronous belt 16, it can synchronously drive the paddle 177 on the synchronous belt 16 to move. The paddle 177 is in an inclined state and is evenly spaced. When the paddle 177 moves and contacts the connecting rod 176, it can drive the connecting rod 176, the rotating shaft 172 and the striking rod 173 to rotate under the action of the inclination. When the gap between the connecting rod 176 and the two paddles 177 is separated from the paddles 177, the rotating shaft 172, the striking rod 173 and the striking head 175 can be reversed under the action of the torsion spring 174, thereby achieving the striking of the steel bar, so that the grinding debris adhered to the steel bar can be shaken off, so as to facilitate the subsequent application of the anti-rust oil agent; when the coating wheel 12 rotates, it can synchronously drive the driving rod 132 to rotate, and when the driving rod 132 rotates, it can drive the driving block 133 to rotate. The driving block 133 rotates, and the side surfaces opposite to the extrusion block 134 are set to corresponding inclined planes. Therefore, when the driving block 133 rotates, the extrusion block 134 can slide back and forth on the inner wall of the fixed shell 131 through the guide groove 135 and the guide block 136 under the action of the inclined plane, thereby squeezing and stretching the oil bag 137. Since the oil suction pipe 138 and the oil supply pipe 139 are equipped with one-way valves with opposite flow directions, the anti-rust oil in the oil storage tank 14 can be drawn into the oil bag 137 through the oil suction pipe 138 when the oil bag 137 is stretched, and the anti-rust oil inside can be added to the outer wall of the coating wheel 12 through the oil supply pipe 139 when the oil bag 137 is squeezed. When the steel bar passes through the two coating wheels 12, the two coating wheels 12 rotate to evenly coat the anti-rust oil on the outer wall of the steel bar, ensuring that the steel bar is more durable when used after unloading.
